DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example 1

[0019] See also Figures 1 to 3 , which is the first embodiment of the utility model, and this embodiment provides a technical solution: a detection fixture that is easy to position, including a fixture substrate 1 and a detection slot 11 opened on the top of the fixture substrate 1, a product 2 to be detected is placed in the detection slot 11, and the top of the fixture substrate 1 is evenly provided with four positioning structures relative to the surroundings of the detection slot 11. The positioning structure includes a cylindrical movable seat 31 movably mounted on the top of the fixture substrate 1, and a pressing plate 33 is rotatably mounted on the top of the cylindrical movable seat 31. One end of the pressing plate 33 The bottom of the pressure plate 33 is fixed to the top of the detection groove 11, and a bottom block 34 is fixed to the bottom of one end of the pressure plate 33, a pressure block 35 is fixed to the bottom surface of the bottom block 34, and a pressure pad 36 that fits tightly with the product to be detected 2 is installed on the bottom surface of the pressure block 35. While ensuring the stability of the clamping and positioning, the pressure pad 36 will not cause damage to the product to be detected. The positioning structure also includes an inner groove 39 opened inside the fixture substrate 1, and a spring 310 and an inner slide plate 311 are arranged in the inner groove 39. The bottom end of the cylindrical movable seat 31 passes through the inner groove 39. The inner slide plate 311 is fixedly connected to the inner slide plate 311. Under the pushing action of the spring 310, the cylindrical movable seat 31 continuously applies a downward pulling force to the pressure plate 33 to ensure that the pressure pad 36 stably presses and positions the product 2 to be tested. After the test of the product 2 to be tested is completed in the later stage, the pressure plate 33 can be lifted, so that the cylindrical movable seat 31 pulls up the inner slide plate 311 and compresses the spring 310, so that the pressure pad 36 can be smoothly lifted out of the test slot 11, and then the pressure plate 33 is rotated so that the pressure block 35 and the pressure pad 36 are both lifted out of the test slot 11. By rotating and moving the top of the detection groove 11, it will no longer cause any positioning and obstruction to the product 2 to be detected. At this time, the product 2 to be detected can be taken and placed. After the product 2 to be detected is placed in the detection groove 11 in the early stage, it is only necessary to lift and rotate the pressure plate 33 so that the pressure pad 36 is on the top of the product 2 to be detected, and then release the pressure plate 33, so that the spring 310 pushes the inner slide plate 311 back, so that the pressure plate 33 moves downward with the bottom block 34, and finally the pressure block 35 and the pressure pad 36 press the product 2 to be detected into position.

[0020] Among them, a circular hole 13 corresponding to the cylindrical movable seat 31 is opened on the inner wall of the top end of the inner groove 39, and the circular hole 13 is communicated with the top surface of the fixture substrate 1 to facilitate the smooth penetration of the cylindrical movable seat 31 and subsequent lifting and lowering activities.

[0021] The bottom end of the spring 310 is in close contact with the inner slide plate 311 , and the top end of the spring 310 is against the top inner wall of the inner groove 39 , so that the spring 310 is stably installed.

[0022] A T-shaped shaft block 32 is fixed on the top surface of the cylindrical movable seat 31 , and the pressing plate 33 is rotatably sleeved on the T-shaped shaft block 32 , so that the pressing plate 33 can smoothly rotate on the top of the cylindrical movable seat 31 .

[0023] Among them, the top surface of the fixture substrate 1 is symmetrically provided with two rectangular limit grooves 12 on both sides of the cylindrical movable seat 31, and the position of the rectangular limit groove 12 corresponds to the pressure pad 36, so that after the operator lifts the pressure plate 33, the pressure plate 33 can be continuously lifted up, causing the pressure pad 36 to move out of the detection groove 11. At this time, the pressure plate 33 can be rotated around the T-shaped shaft block 32 until the pressure pad 36 is rotated to the top of the rectangular limit groove 12. At this time, the pressure plate 33 is released, and the pressure pad 36 can be stuck in the rectangular limit groove 12, thereby realizing auxiliary positioning of the pressure plate 33 and the pressure pad 36, which is convenient for the operator to take and place the product 2 to be tested.

[0024] Example 2

[0025] See also Figures 1 to 4 , which is the second embodiment of the utility model, is based on the previous embodiment, and the difference is that the pressure pad 36 can be conveniently disassembled, assembled and replaced by the provided insert block 37 and the triangular clamp block 38.

[0026] Specifically, two plug blocks 37 are symmetrically arranged on the top surface of the pressure pad 36, and the plug blocks 37 and the pressure pad 36 are an integrated structure. The surface of the pressure block 35 is symmetrically provided with two sockets 351 corresponding to the plug blocks 37, and the top of the plug block 37 passes through the socket 351 to the top of the pressure block 35, and an integrated triangular clamping block 38 is arranged on the top surface of the plug block 37. The plug block 37, the pressure pad 36 and the triangular clamping block 38 are all made of rubber material, and the triangular clamping block 38 is clamped on the top surface of the pressure block 35 to achieve stable installation of the pressure pad 36. If the pressure pad 36 is to be removed and replaced later, it is only necessary to pull down the pressure pad 36 with force, so that the plug block 37 and the triangular clamping block 38 are squeezed and elastically deformed, and finally pulled out from the bottom end of the socket 351, and the pressure pad 36 can be successfully removed from the bottom of the pressure block 35.

[0027] A deformation cavity 371 is provided inside the top of the insert block 37 , and the position of the deformation cavity 371 corresponds to the triangular clamping block 38 , so that the triangular clamping block 38 has sufficient deformation space when being squeezed.

[0028] Although the embodiments of the present invention have been shown and described (see the above detailed description for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
