DETAILED DESCRIPTION

[0022] 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.

[0023] The utility model provides a clamping mechanism for circuit board maintenance, comprising a base 1, a rotating mechanism 2 for clamping and rotating is arranged on the top of the base 1, a pushing mechanism 3 for elastic clamping is arranged on the top of the base 1, an auxiliary mechanism 4 for adapting to the rotating mechanism 2 is arranged at the other end of the top of the base 1, and the rotating mechanism 2 comprises a first support plate 21, and the first support plate 21 is slidably connected to the top of the base 1;

[0024] The upper part of one side of the first support plate 21 is rotatably connected with the first connecting rod 22, one end of the first connecting rod 22 is fixedly installed with the first clamp 23, the other end of the first connecting rod 22 is fixedly installed with a turntable 24, the upper part of one side of the turntable 24 is threadedly connected with a screw rod 25, one end of the screw rod 25 is fixedly installed with a support plate 26, which has the effect of clamping and fixing the circuit board while achieving a flipping effect, so that maintenance work can be carried out after flipping to the required angle.

[0025] A circular groove 27 is formed on one side of the first support plate 21 , and the abutment plate 26 is located inside the circular groove 27 . The circular groove 27 is used to limit the abutment plate 26 so that the abutment plate 26 is stabilized inside the circular groove 27 .

[0026] When the circuit board is located between the second clamp 43 and the first clamp 23 and is pushed and clamped by elastic force, the rotation operation can be realized;

[0027] The turntable 24 is directly rotated, and the first clamp 23 is driven to rotate together by the turntable 24 through the first connecting rod 22, and the first clamp 23 indirectly drives the second clamp 43 to rotate through the elastically clamped circuit board. Since the second clamp 43 is rotatably connected with the second support plate 41, the circuit board can be turned over to adjust the inspection angle.

[0028] Once adjusted to the desired position, the locking operation can be performed:

[0029] Directly rotate the screw rod 25, and utilize the threaded connection between the screw rod 25 and the turntable 24 to push the abutment plate 26 to move inside the ring groove 27 until the abutment plate 26 is pressed against the inner wall of the ring groove 27, and the pressing surface of the abutment plate 26 is provided with anti-slip grooves to improve the pressing effect. At this time, the locking work after the flip angle adjustment can be completed to avoid the occurrence of free rotation.

[0030] like Figure 1 As shown, the auxiliary mechanism 4 includes a second support plate 41, which is fixedly mounted on one end of the top of the base 1, and one side of the second support plate 41 is rotatably connected to a second connecting rod 42, and one end of the second connecting rod 42 is fixedly mounted with a second clamp 43. The second support plate 41 can support the second connecting rod 42 and the second clamp 43 for rotation, and the second support plate 41 cooperates with the first clamp 23 to complete the auxiliary clamping operation of the circuit board.

[0031] Preferably, the pushing mechanism 3 includes a sliding component, a supporting component and an elastic component, the sliding component is arranged on both sides of the top of the base 1, the supporting component is arranged on the top of the base 1, and the elastic component is arranged on one side of the supporting component.

[0032] like Figure 2 As shown, the sliding assembly includes a slide groove 31, which is respectively opened on both sides of the top of the base 1. The inside of the slide groove 31 is slidably connected with a slider 32. The top of the slider 32 is fixed to the bottom end of the first support plate 21 to realize sliding limiting work.

[0033] like Figure 2 As shown, the support assembly includes a connecting block 33 and an adapting groove 34. The connecting block 33 is fixedly installed at the bottom end of the first support plate 21, and the adapting groove 34 is opened at the top of the base 1. The connecting block 33 is located inside the adapting groove 34 to assist in supporting the connection.

[0034] like Figure 2 As shown, the elastic component includes a pull rod 35 and a spring 36. The pull rod 35 and the spring 36 are both fixedly mounted on one side of the connecting block 33. The spring 36 is located on the outside of the pull rod 35. One end of the pull rod 35 slides through one end of the base 1 to facilitate the clamping operation of the circuit board after elastic pushing.

[0035] When clamping:

[0036] First, pull the pull rod 35 outward, and use the pull rod 35 to drive the connecting block 33 to slide inside the adapter groove 34, and simultaneously squeeze the spring 36. At the same time, the connecting block 33 pulls the first support plate 21 to move together until the distance between the second clamp 43 and the first clamp 23 increases, and at the same time, the slider 32 slides inside the slide groove 31, and it is beneficial to achieve the limiting function. After that, the circuit board is placed between the second clamp 43 and the first clamp 23, and then the pulling force is slowly released. The spring 36 pushes according to the elasticity to cause the first support plate 21 to drive the first clamp 23 to move and cooperate with the fixed second clamp 43 to clamp and fix the circuit board.
