Description

A kind of disk centrifuge cover is opened fixing and locking device

One, technical field:

The present invention relates to a kind of disk centrifuge, be specifically related to a kind of disk centrifuge cover and open fixing and locking device.

Two, background technology:

Disk centrifuge is a kind of multi-functional, high efficiency thin layer separation machinery, is widely used in the industries such as rubber, pharmacy, food.Cover covers on body upper, forms separated space together with fuselage, and mask work is carried out in the group of transferring shares rotation in the space of fuselage and cover composition.In process of production, people often need to be to the disk centrifuge examination and maintenance of being uncapped, heavy cover open after due to can't position and lock or position and lock unstable, return voluntarily usually, cause very large potential safety hazard to the personnel that carry out examination and maintenance, sometimes also can damage machine.

Three. summary of the invention:

The object of the present invention is to provide a kind of disk centrifuge cover simple in structure, easy for installation, that position and lock is stable to open fixing and locking device.

For achieving the above object, a kind of disk centrifuge cover of the present invention is opened fixing and locking device, described cover opening locating device comprises cover and fuselage, the cover side is fixed with the hinge bracket I, the fuselage side is fixed with the hinge bracket II, hinge bracket I and hinge bracket II are staggered and are flexibly connected by rotating shaft, are fixed with the pulling ear that a triangle protrudes in the outer end of described hinge bracket I one side, and the outside, upper end of pulling ear is provided with the groove at a right angle; The outside and the pulling ear correspondence position of the hinge bracket II corresponding with pulling ear the same side are respectively equipped with limiting plate and lock, limiting plate is the strip plate, fixedly be located at the inboard of the hinge bracket II outside near fuselage, lock Cheng Chang garden column, the body outside far away of disembarking, the hinge bracket II outside that install by the rotating shaft activity side of lock, pulling ear, limiting plate are corresponding with lock three's position.

Owing to having taked technique scheme, the pulling ear that cover after unlatching protrudes by the triangle that is located at cover lateral hinges support I outer end rotates between the limiting plate and lock of the fuselage lateral hinges support II outside and pulling ear correspondence position, then in the right angle groove that embeds the outside, pulling ear upper end by lock by the pulling ear position and lock between limiting plate and lock, thereby the cover position and lock after opening, making originally need to cooperate the lower examination and maintenance work simplification of uncapping that just can complete two people is that a workman is achievable work, have simple in structure, easy for installation, lock stable advantage.

Four, accompanying drawing explanation:

Fig. 1 is the structural representation that a kind of disk centrifuge cover of the present invention is opened fixing and locking device;

Fig. 2 is that shown in Fig. 1, a kind of disk centrifuge cover is opened the local structure for amplifying schematic diagram in the fixing and locking device opening process;

Fig. 3 is the local structure for amplifying schematic diagram that shown in Fig. 1, a kind of disk centrifuge cover is opened the fixing and locking device lock-out state.

Five, the specific embodiment:

Below in conjunction with embodiment, the present invention is further detailed explanation.

From Fig. 1, Fig. 2 and Fig. 3, a kind of disk centrifuge cover of the present invention is opened fixing and locking device and is comprised cover 1 andfuselage 3, cover 1 side is fixed with hinge bracket I 2,fuselage 3 sides are fixed with hinge bracket II 4, hinge bracket I 2 and hinge bracket II 4 are staggered and overlappingly are flexibly connected by rotating shaft, the hinge bracket II 4 offuselage 3 sides is clipped between the hinge bracket I 2 of cover 1 side, be fixed with the pullingear 5 that a triangle protrudes in the outer end of described hinge bracket I 2 one sides, the outside, upper end of pullingear 5 is provided with the groove at a right angle; The outside and pullingear 5 correspondence positions of the hinge bracket II 4 corresponding with pullingear 5 the same sides are respectively equipped withlimiting plate 6 andlock 7, limitingplate 6 is the strip plate, fixedly be located at the inboard of hinge bracket II 4 outsides nearfuselage 3, lock 7 Cheng Chang garden columns, body 2 outside far away of disembarking, hinge bracket II 4 outsides that install by the rotating shaft activity side oflock 7, the lower end oflock 7 is slightly long, be the state of naturally drooping while not working, should match with the right angle groove in the pullingear 5 upper ends outsides in the upper end oflock 7, pullingear 5, limitingplate 6 are corresponding withlock 7 threes' position.

When disk centrifuge needs examination and maintenance, open cover, the upper end that pullingear 5 is stirredlock 7 with hinge bracket I 2 rotations that are fixedly connected with cover 1, when a limit of the pullingear 5 of protruding when triangle comes to limitingplate 6, lock 7 embeds in the right angle groove in the outside, pulling ear upper end just, pullingear 5 is positioned and is locked between limitingplate 6 andlock 7, because pullingear 5 is fixedly connected with hinge bracket I 2, and hinge bracket I 2 is fixedly connected with cover 1, rotation by position and lock pullingear 5 restriction covers 1, thereby reach the purpose that position and lock is opened rear cover 1.After examination and maintenance finish, lift the slightly long end in outer end oflock 7, an end that makeslock 7 embed pullingear 5 right angle grooves moves down, now pullingear 5 breaks away from the position and lock state, cover 1 is closed in rotation, put downlock 7 the slightly long end oflock 7 is naturally drooped, thereby complete the examination and maintenance work that cover 1---position and lock---is closed cover 1 of opening.

A kind of disk centrifuge cover of the present invention is opened fixing and locking device and has been realized the automatic positioning lock of the cover 1 after opening is determined by the pullingear 5 on the hinge that is located at cover 1 andfuselage 3, limitingplate 6 andlock 7, the return voluntarily of cover 1 after having prevented from opening, reduced the risk of the personnel of examination and maintenance after cover 1 is opened, also reduced the spoilage of mechanical fitting, have advantages of simple in structure, easy for installation, lock stable.
