Description

Technical Field

[0001] The utility model relates to a detection fixture, in particular to a communication camera detection fixture, and belongs to the technical field of communication equipment maintenance. Background Art

[0002] Communication cameras are a kind of modern monitoring equipment, which are widely used in various occasions, including homes, shopping malls, schools, roads and other public areas. Their main function is to collect images and video information in real time and transmit them to the designated monitoring center or user terminal through the communication network to achieve remote observation, recording and playback. Communication cameras are generally composed of lenses, sensors, digital processing units, communication modules and other parts. The diameter of the camera lens will directly affect the imaging effect and aperture size of the camera. Communication camera detection usually refers to the process of checking and evaluating the working status, image quality, safety performance, etc. of the camera. Therefore, when testing the communication camera lens, the lens needs to be clamped;

[0026] In one embodiment, guide grooves 13 are provided on the inner walls on both sides of the first rectangular hole 4, and guide blocks 12 are fixedly installed on both sides of the clamping plate 2. The outer side of the guide block 12 is in movably contact with the inner wall of the guide groove 13. The guide block 12 cooperates with the guide groove 13 to achieve guidance of the clamping plate 2 when it moves.

[0027] In one embodiment, a connecting rod 602 is rotatably mounted on the top of the inner wall of the groove 101, and the bottom end of the connecting rod 602 extends to the bottom of the placement seat 1. A handle 601 is fixedly mounted on the bottom end of the connecting rod 602. A first bevel gear 603 is fixedly sleeved on the outer side of the connecting rod 602. Three internal threaded cylinders 605 are rotatably mounted on the top of the inner wall of the placement seat 1. The internal threads of the internal threaded cylinders 605 are connected to threaded rods 606. The ends of the three threaded rods 606 that are far away from each other are fixedly connected to the sides of the three clamping plates 2 that are close to each other. The three internal threaded cylinders 605 are mutually A second bevel gear 604 is fixedly installed at the end close to it. The three second bevel gears 604 cooperate with the first bevel gear 603. By rotating the handle 601, the connecting rod 602 is driven to rotate, and the connecting rod 602 drives the first bevel gear 603 to rotate. The rotating first bevel gear 603 drives the three second bevel gears 604 that cooperate with it to rotate. The rotation of the three second bevel gears 604 also drives the three internal threaded tubes 605 to rotate, so that the three threaded rods 606 drive the three clamping plates 2 to move inward or outward, thereby clamping the camera.

[0028] In one embodiment, a first bearing 7 is fixedly installed on the top of the inner wall of the groove 101 , and the inner wall of the first bearing 7 is fixedly connected to the outer side of the connecting rod 602 . The connecting rod 602 is rotatably installed on the top of the inner wall of the groove 101 through the setting of the first bearing 7 .

[0029] In one embodiment, a through hole 11 is formed on the upper surface of the first bevel gear 603 , and the inner wall of the through hole 11 is fixedly connected to the outer side of the connecting rod 602 . The through hole 11 allows the first bevel gear 603 to be fixedly sleeved on the outer side of the connecting rod 602 .

[0030] In one embodiment, three rectangular plates 8 are fixedly installed on the top of the inner wall of the groove 101, and a circular hole 9 is opened on one side of the three rectangular plates 8. A second bearing 10 is fixedly installed inside the circular hole 9. The inner wall of the second bearing 10 is fixedly connected to the outer side of the internal threaded tube 605. The internal threaded tube 605 is rotatably installed on the top of the inner wall of the groove 101 through the provision of the second bearing 10.

[0031] When the utility model is in operation: the camera to be tested is placed on the upper surface of the placement seat 1, and the handle 601 is rotated clockwise, so that the handle 601 drives the connecting rod 602 to rotate, and the rotating connecting rod 602 drives the first bevel gear 603 to rotate. Since the first bevel gear 603 cooperates with the three second bevel gears 604, the first bevel gear 603 rotates and drives the three second bevel gears 604 to rotate at the same time, and the rotating second bevel gear 604 drives the internal threaded cylinder 605 to rotate. Since the internal threaded cylinder 605 and the threaded rod 606 are threadedly matched, the three internal threaded cylinders 605 rotate and drive the three threaded rods 606 to move in a direction close to each other. At the same time, the three threaded rods 606 drive the three clamping plates 2 to move in the opposite direction close to the camera until the inner sides of the three protective cushions 3 contact the outer sides of the camera to clamp the camera, so that the three clamping plates 2 can be moved inward at the same time to clamp cameras of different diameters by rotating the handle 601, thereby improving the stability of the camera and expanding the scope of application of the clamp.

[0032] After the detection is completed, the handle 601 is rotated counterclockwise so that the handle 601 drives the connecting rod 602 to rotate, the connecting rod 602 drives the first bevel gear 603 to rotate, the rotating first bevel gear 603 drives the three second bevel gears 604 to rotate, the three second bevel gears 604 drive the three internal threaded cylinders 605 to rotate, and the three internal threaded cylinders 605 rotate while driving the three threaded rods 606 to move away from each other, so that the three threaded rods 606 drive the three clamping plates 2 to move away from each other, and the camera can be released from the top of the placement seat 1.

[0033] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
