Utility model content

In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of test of video camera hinge dresses It sets, have the advantages that easy to operate, high-efficient and staff is required low to have.

To achieve the above object, the utility model provides following technical solution:

A kind of experimental rig of video camera hinge, including workbench, workbench offer hollow installation cavity, workbench Top surface offer link slot, link slot extends along the length direction of workbench and communicates with installation cavity, and bench top opens up There are several the first clamping grooves for connecting block cooperation with first, the first clamping groove communicates with link slot and along the extending direction of link slot point Cloth is provided with the positioning component for deviateing the first clamping groove for limiting first company's block on workbench, is rotatably connected in installation cavity Several and one-to-one second mounting blocks of the first clamping groove, the second mounting blocks offer the second clamping for connecting block cooperation with second Slot is provided with the driving assembly for driving each second mounting blocks to rotate synchronously along height of table direction in installation cavity.

By adopting the above technical scheme, when needing to detect video camera hinge, the first of each video camera hinge is connected Block is caught in the first clamping groove, and second company's block is caught in corresponding second clamping groove, and wherein connector and bull stick pass through link slot, lead to Component of overdriving drives each second mounting blocks synchronous reciprocating rotation, and the axis weight of the pivot center of the second mounting blocks and bull stick It closes, to realize that second company's block removes video camera after predetermined amount along the axis reciprocating rotation of bull stick relative to first company's block Hinge, checks whether the video camera hinge damages, and has the advantages that easy to operate, and common staff also can be carried out operation, To reduce the requirement to staff；By the way that several first clamping grooves and the second mounting blocks are arranged, synchronous detection is realized Multiple video camera hinges, improve work efficiency.

Further, the first clamping groove is along the center line and link slot of workbench length direction along workbench length direction Center line is overlapped.

By adopting the above technical scheme, it passes through link slot from the center of the first clamping groove, bull stick is made to pass through link slot, and the The both ends of one company's block are uniformly distributed in the two sides of link slot, to make first company's block uniform force, improve video camera hinge peace The stability of dress.

Further, driving assembly includes cylinder, rack gear and several gears, and gear is set with the second mounting blocks one-to-one correspondence It sets, gear is fixed on the bottom surface of the second mounting blocks, and Gear axis is arranged along the short transverse of workbench；Rack gear and workbench slide It connects and synchronization is engaged with each gear；Cylinder is fixed on the worktable and fixes with telescopic shaft and rack gear.

By adopting the above technical scheme, when needing to be measured experiment, cylinder is driven, drives the telescopic shaft of cylinder along work The length direction of platform moves back and forth, so that the length direction with carry-over bar along workbench moves back and forth, then each tooth of synchronous drive Wheel and the rotation of the second mounting blocks synchronous reciprocating realize that second connects block relative to first company's block reciprocating rotation.

Further, positioning component includes cover board, the Ruo Ganshe for being rotationally connected on workbench and being used to close link slot It is placed in cover board inner wall and abuts bar when the closure is closed with the abutting bar of the first clamping groove location cooperation and be caught in the first clamping First in slot, which connects block, abuts.

By adopting the above technical scheme, before being measured test, rotating plate makes cover closure installation cavity, supports simultaneously Extension bar is abutted with first company's block, so that second connects block during rotation, is reduced first and is connected the probability that block is detached from the first clamping groove.

Further, the one end for abutting bar passes through cover board, abuts and is threaded with two nuts on bar, and cover board is located at two spiral shells Between mother.

By adopting the above technical scheme, it by the way that two nuts are arranged, to realize to the height adjustment for abutting bar, conveniently adapts to each The depth of first clamping groove improves whole stability.

Further, it abuts bar and is fixed with elastomer block far from one end of cover board, and elastomer block and be caught in the first clamping groove First connect block interference fit.

By adopting the above technical scheme, by the way that elastomer block is arranged, elastomer block connects block interference fit with first, to reduce to the One connects the friction injury of block.

Further, it is provided with handle on cover board, several bearing blocks are provided on handle.

By adopting the above technical scheme, by the way that handle is arranged, consequently facilitating cover board rotation is driven, by the way that bearing block is arranged, from And when cover closure installation cavity, cover board, which is limited, under the action of load-bearing plate shakes.

Further, handle is rotationally connected on cover board, and the groove with bearing block cooperation is fixed on workbench.

By adopting the above technical scheme, by the way that groove is arranged, consequently facilitating placing bearing block.

Compared with prior art, the utility model has the advantages that:

(1) first company's block of several video camera hinges is caught in the first clamping groove, second company's block is caught in corresponding second clamping In slot, drives each second to connect block by driving assembly and connect block along the axis reciprocating rotation of shaft, in predetermined amount relative to second Afterwards, remove video camera hinge, check whether the video camera hinge damages, have the advantages that it is easy to operate, and reduce to work people The requirement of member；

(2) it by cover closure installation cavity, while abutting bar and being abutted with first company's block, so that second connects block in rotation process In, it reduces first and connects the probability that block is detached from the first clamping groove.
