Abstract

The invention discloses a sweeper side brush handle connecting structure which comprises a motor, an elastic bolt and a side brush handle. An output shaft end of the motor is inserted in a shaft sleeve of the side brush handle, the output shaft end of the motor is connected with the shaft sleeve of the side brush handle through a key, a groove is arranged on the outer wall of the shaft sleeve, a pin hole perpendicular to the shaft sleeve and taking the key as the center is drilled in the groove, and correspondingly, same pin holes are arranged at the output shaft end of the motor and on the key respectively. The elastic bolt is a clamp with a bent opening, a straight rod end is longer than a bent end before mounting, and the straight rod end and the bent end lean against each other abreast. The motor output shaft end matched with the key is matched with the shaft sleeve and aligned with the pin holes, and the elastic bolt is held by hands to enable the straight rod end to transversely penetrate through the pin holes and enable the bent end to elastically expand along the groove on the outer wall of the shaft sleeve until elastic clamping is realized. The sweeper side brush handle connecting structure is free of special tools during mounting and demounting, simple and convenient to operate, easy to replace the side brush handle, free of stopping at a special table position to realize operations and quite convenient for operating personnel to replace the side brush handle timely and nearby.

Description

Sweeper limit brush handle syndeton

Technical field

The present invention relates to a kind of mechanical connecting structure, specifically, the present invention relates to a kind of sweeper limit brush handle syndeton.

Background technology

The limit brush handle is a kind of conical sleeve shape brush, and the limit brush handle that is installed in the sweeper two bottom sides is mainly used in cleaning the edge, roadside.Because the limit brush handle that rotates in the process of sweeping the floor directly contacts with ground, bristle has normal wearing and tearing, and changing the limit brush handle that lost efficacy is one of General Maintenance maintenance task.The limit brush handle is connected with the output shaft end of necessary electromotor and usually adopts screw radially to lock syndeton in the prior art.This syndeton is simple, easy to manufacture, can satisfy driving limit brush handle and rotate the requirement of sweeping the floor.But the limit brush handle that is positioned at the sweeper bottom is overhead nearer, and the operating space is narrow, and adding dismounting or holding screw is installed needs corresponding special tool, needs to carry out in the private station position so change failed limit brush handle.Although can accomplish effective replacing on the private station position, it is poor to change promptness, and unloading process is long, and work efficiency is poor.

Summary of the invention

The present invention is mainly for the deficiencies in the prior art, propose a kind of simple in structure, connect reliable, dismantle easily sweeper limit brush handle syndeton.

The present invention is achieved through the following technical solutions technical goal.

Sweeper limit brush handle syndeton, it comprises motor, resilient pin and limit brush handle.Described motor output shaft end inserts in the axle sleeve of limit brush handle, and both connect by key.Described axle sleeve is provided with flange, and ring smaller diameter end outer wall is provided with groove, in groove centered by key vertical axle sleeve outer wall drilling pin-and-hole, the motor output shaft end and the key that match also are shaped with identical pin-and-hole.Its improvements are: described resilient pin is opening bending folder member, the straight-bar end that leans on mutually side by side before not installing is than the long 5mm～10mm of curved end, the curved end head is the outward opening shape, rearmounted one section waveform circular arc, resilient pin consists of pin connected construction with the pin-and-hole that the straight-bar end laterally runs through on axle sleeve, motor output shaft end and the key, curved end direct-axis cover unit with grooves in outer wall elastic dilatation in the plug-in mounting process is until the waveform arc section of evagination and groove fit consist of the resilient clamp structure.

In the said structure, the waveform circular arc radius of curvature of resilient pin curved end evagination equals half of axle sleeve unit with grooves in outer wall base diameter.Be bent into ring tab shape on the resilient pin straight-bar end, draw ring incurvature radius 8mm～10mm.

The present invention compared with prior art has following good effect:

1, pin connected construction is simple, and dismounting does not need special tool, and is swift to operate;

2, it is accurate that resilient pin is installed rear screens, reliable transmission.

The specific embodiment

The invention will be further described with reference to the accompanying drawings for the below.

Sweeper limit brush handle syndeton, it comprises motor 1,resilient pin 2 and limit brush handle 3.Described motor 1 output shaft end inserts in the axle sleeve 3.1 oflimit brush handle 3, and both connect by key 1.1.Described axle sleeve 3.1 is provided with flange, and ring smaller diameter end outer wall is provided with groove 3.2, in groove 3.2 centered by key 1.1 vertical axle sleeve 3.1 outer wall drilling pin-and-holes, motor 1 output shaft end and the key 1.1 that match also are shaped with identical pin-and-hole.Describedresilient pin 2 is opening bending folder member, and the straight-bar end that leans on mutually side by side before not installing is longer than curved end, the long 5mm of present embodiment.Resilient pin 2 curved end heads are the outward opening shape, rearmounted one section waveform circular arc, and the radius of curvature of this circular arc equals half of axle sleeve 3.1 unit with grooves in outer walls 3.2 base diameters, and present embodiment is 12.5mm.Resilient pin 2 consists of pin connected construction with the pin-and-hole that the straight-bar end laterally runs through on axle sleeve 3.1, motor 1 output shaft end and the key 1.1.The curved end direct-axis overlaps 3.1 unit with grooves in outer walls, 3.2 elastic dilatations in the plug-in mounting process, consists of the resilient clamp structure until the waveform arc section of evagination cooperates with groove 3.2.For the ease of dismountingresilient pin 2, be bent into ring tab shape on the straight-bar end afterbody, draw ring incurvature radius is 8mm, this size is enough to hold into finger and stretches into pulling, extractsresilient pin 2, can unload followingbrush handle 3 and change.The present invention does not all need special tool in the installation and removal process, easy and simple to handle, and thebrush handle 3 of more changing sides is easy, do not need to stop the private station position and just can realize operation, greatly the handled easilypersonnel brush handle 3 of more changing sides as required because thelimit brush handle 3 of wearing and tearing is in time changed, is guaranteed the highway section cleaning quality.
