Detailed Description of the Preferred Embodiment
[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0024] Refer to Figures 1 - 3, an embodiment provided by the present utility model: a positioning fixture for a special-shaped security back cover, including a mounting frame 1. A fixture 4 is slidably connected to the inner wall of the top of the mounting frame 1. A security monitoring back cover 5 is clamped to the outer wall of the side of the fixture 4. A positioning mechanism 7 is provided on the fixture 4. By setting the positioning mechanism 7, strain adjustment clamping and positioning are carried out on different special-shaped security back covers. An adjustment mechanism 8 is provided on the positioning mechanism 7. By setting the adjustment mechanism 8, the stacking thickness of the clamping plates 74 is adjusted to be suitable for the auxiliary clamping and fixing of different security back covers. The positioning mechanism 7 includes a positioning groove 71. The positioning groove 71 is opened on the inner wall of one side of the fixture 4. A sliding frame 72 is slidably connected to the inner walls on both sides of the positioning groove 71. A chute 73 is opened on the inner wall of one side of the sliding frame 72. By setting the chute 73, the clamping plate 74 slides smoothly in a telescopic manner. A clamping plate 74 is slidably connected to the inner wall of one side of the chute 73. An arc-shaped tooth 75 is hinged to the inner wall of one side of the clamping plate 74. By setting the arc-shaped tooth 75, when it fits the surface of the special-shaped security back cover, the angle is adjusted adaptively.
[0025] Refer to Figures 2 - 4 , there are two clamping plates 74 in total. The two clamping plates 74 are symmetric with each other. There are several arc-shaped teeth 75. The several arc-shaped teeth 75 are respectively hinged to the inner wall of one side of the clamping plate 74. The fixture 4 is threadedly connected to the bidirectional threaded rod 2. A spring damper 76 is fixedly connected to the inner wall of one side of the clamping plate 74. By setting the spring damper 76, a continuous thrust is generated on the clamping plate 74, so that the clamping plate 74 plays a flexible clamping role, preventing problems such as over-tightening or over-loosening during clamping, which may cause wear and damage to the special-shaped security back cover. One end of the spring damper 76 away from the arc-shaped tooth 75 is fixedly connected to the inner wall of one side of the sliding frame 72. A frosted pad is fixedly connected to the outer wall of one side of the arc-shaped tooth 75. The inner walls on both sides of the mounting frame 1 are rotatably connected to a bidirectional threaded rod 2 through bearings. A driving machine 3 is fixedly connected to the outer wall of one side of the mounting frame 1. By setting the driving machine 3, the bidirectional threaded rod 2 is driven to rotate and start and stop. One end of the bidirectional threaded rod 2 is fixedly connected to the output end of the driving machine 3 through a coupling. A fixing plate 6 is fixedly connected to the outer wall of the top of the mounting frame 1.
[0026] Refer to Figures 3 - 4 , the adjustment mechanism 8 includes a positioning cylinder 81. The positioning cylinder 81 is fixedly connected to the inner wall of one side of the positioning groove 71. A bolt 82 is threadedly connected to the inner wall of the top of the positioning cylinder 81. By setting the bolt 82 to cooperate with the adjustment disc 83, the sliding frame 72 is assembled and disassembled and separated. The top end of the bolt 82 is fixedly connected to an adjustment disc 83. A pressing plate 84 is fixedly connected to the outer wall of the bottom of the adjustment disc 83. By setting the pressing plate 84, the outer wall of one side of the sliding frame 72 is clamped and fixed to prevent the sliding frame 72 from loosening. A silica gel pad is fixedly connected to the outer wall of the side of the adjustment disc 83. The pressing plate 84 is clamped to the outer wall of one side of the sliding frame 72. A wear-resistant pad is fixedly connected to the outer wall of the bottom of the pressing plate 84.
[0027] Working principle: By turning on the drive machine 3, the bidirectional threaded rod 2 rotates. The rotation of the bidirectional threaded rod 2 drives two clamps 4 to close and unfold with each other, causing the clamps 4 to move and drive the sliding frame 72 to move. The movement of the sliding frame 72 drives the clamping plate 74 to move, and the movement of the clamping plate 74 drives the arc-shaped tooth 75 to move. When the arc-shaped tooth 75 fits the surface of the special-shaped security back cover, the clamping angle of the arc-shaped tooth 75 adapts to the change according to the radian. At the same time, when the arc-shaped tooth 75 is clamped and stressed, it causes the clamping plate 74 to move, and the clamping plate 74 moves to squeeze the spring damper 76, so that the arc-shaped tooth 75 flexibly clamps and fixes the special-shaped security back cover, and at the same time buffers the external vibration received by the security monitoring back cover 5. When positioning, installing and clamping different special-shaped security back covers, by stacking multiple sliding frames 72 on the positioning cylinder 81, and then rotating the adjustment disc 83 to make the bolt 82 rotate. The bolt 82 and the positioning cylinder 81 are telescopically adjusted, so that the movement of the adjustment disc 83 drives the abutting plate 84 to move, and the movement of the abutting plate 84 presses and clamps the outer wall of one side of the sliding frame 72 to prevent loosening.
