A kind of headTechnical field
This utility model is related to a kind of head, the head of espespecially a kind of rotatable adjustment camera angle.
Background technology
Existing head is divided into be fixed and electronic two kinds, and fixing head is adapted to monitor for the little situation of scope, is fixingThe adjustable level of video camera and the angle of pitching after video camera is installed on head, as long as locking after reaching best operating attitudeDetermine guiding mechanism just permissible.But this kind of fixing head operates cumbersome when adjustment, loses time.
Utility model content
The purpose of this utility model is to provide a kind of head, and this head low cost is reasonable in design, and easy for installation, operation is justVictory, is suitable for providing a supporting role under various adverse circumstances.
This utility model solves its technical problem and be employed technical scheme comprise that：
A kind of head, including supporting table, base and alignment pin, about described supporting table bottom surface, two ends are provided with perpendicular to supportPlatform and with supporting table integrally formed support, support is had circular arc through hole and the axis hole one being overlapped with the circular arc through hole center of circle；InstituteState two ends about base to be provided with perpendicular to base and the integrally formed locating rack with base, base is provided with fixing hole, locating rackOn have position two location holes corresponding with circular arc through hole two ends and axis hole one and axis hole two respectively；Supporting table and base lead toCrossing bolt connection axis hole one makes both can be dynamically connected with axis hole two；Described alignment pin end surface is provided with screw thread, top and bottomIt is fixed with fixture block, the diameter with diameter greater than location hole of described fixture block；Alignment pin passes through location hole and circular arc through hole, connects and supportsPlatform and base.
Preferably, the width of described circular arc through hole is equal to the diameter of location hole.
Preferably, base is provided with fixing hole.
Preferably, described supporting table and base are made up of aluminium alloy, compare other materials, aluminium alloy is lighter, protectiveCan be more preferably.
Compared to the prior art this utility model, has advantages below and effect：Low cost, reasonable in design, easy for installation,Simple operation, is suitable for providing a supporting role under various adverse circumstances.

Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings and by embodiment, and following examples are rightOf the present utility model explain and this utility model is not limited to following examples.
As shown in Figure 1-Figure 3, this utility model includes supporting table 1, base 2 and alignment pin 3.Two about supporting table 1 bottom surfaceEnd is provided with perpendicular to supporting table 1 and the integrally formed support 11 with supporting table 1, and support 11 has circular arc through hole 12 and and circular arcThe axis hole 1 that through hole 12 center of circle overlaps.Base 2 is provided with fixing hole 21, and base 2 can be fixed on specific bit by fixing hole 21Put.
Base 2 about two ends are provided with perpendicular to base and the integrally formed locating rack 22 with base, and locating rack 22 hasPosition two location holes 23 corresponding with circular arc through hole 12 two ends and axis hole 1 and axis hole 2 24 respectively.Supporting table 1 and bottomSeat 2 is bolted axis hole 1 makes both can be dynamically connected with axis hole 2 24, and supporting table 1 can be lifted with axis hole 1 for axle centerPlay left end or right-hand member.
Alignment pin 3 end surface is provided with screw thread, and top and bottom are fixed with fixture block 31, fixture block 31 with diameter greater than location hole23 diameter.Alignment pin 3 passes through location hole 23 and circular arc through hole 12, connects supporting table 1 and base 2.Alignment pin 3 is arranged on supportBetween platform 1 and base 2, after supporting table 1 is adjusted to specified location, alignment pin 3 can be screwed into location hole 23, make both relatively solidFixed.
In this utility model, the width of circular arc through hole 12 is equal to the diameter of location hole, passes through circular arc through hole using alignment pin12 and location hole 23 so that supporting table 1 and base 2 is relatively fixed.Supporting table 1 and base 2 are made up of aluminium alloy, compare other materials,Aluminium alloy is lighter, and barrier propterty is more preferable.
Embodiment.
Camera head is fixed in supporting table 1.When camera head needs horizontal plane work, do not adjust head, such asShown in Fig. 4.When camera head needs to adjust lower angle on camera lens, two alignment pins 3 are back-outed from location hole 23, alignment pinThe fixture block 31 of 3 rear ends is stuck in inside location hole 23.Now, supporting table 1 can be adjusted.Supporting table 1 can be with axis hole 1Lift one end for axle center, as shown in Figure 5.After the completion of adjustment, then alignment pin 3 is screwed into location hole, completes to fix.
Above content described in this specification is only to this utility model example explanation.This utility modelPerson of ordinary skill in the field can make various modifications or supplement or adopt class to described specific embodimentAs mode substitute, the content without departing from this utility model description or surmount model defined in the claimsEnclose, protection domain of the present utility model all should be belonged to.
