[0024] 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.

[0025] See also Figure 1 - Figure 5 , the utility model provides a technical solution:

[0026] See also Figure 1 - Figure 5 The LCM module testing device is shown, including a base 1, on which a clamping assembly 2 is installed, the clamping assembly 2 includes a rotating rod 201, and two connecting rods 202 are installed on the circumferential outer wall of the rotating rod 201, one end of the connecting rod 202 away from the rotating rod 201 is rotatably connected to a connecting rod 203, and the other end of the connecting rod 203 is connected to a mounting frame 204, and a clamping plate 205 is fixedly installed on the mounting frame 204.

[0027] When the rotating rod 201 is rotated, the rotating rod 201 will drive the two connecting rods 202 to rotate synchronously, and the connecting rod 202 will drive one end of the connecting rod 203 to move toward the two sides of the base 1. The angle between the connecting rod 202 and the connecting rod 203 gradually decreases. The connecting rod 202 drives the mounting frame 204 and the clamping plate 205 to move toward each other through the connecting rod 203. After the two clamping plates 205 run to the width between them, the LCM module is placed in the mounting groove 11, and then the rotating rod 201 is rotated to further fix and clamp the LCM module, and then a vibration test is performed. When clamping and fixing the LCM module, the clamping plates 205 do not need to be fixed one by one, and the clamping assembly 2 will be more convenient when clamping the LCM module, and the clamping work efficiency will be higher.

[0028] See also Figure 3 Two sliding grooves 12 are provided on the top of the base 1 , and a limit rod 10 is fixedly installed on the inner wall of the sliding groove 12 , and the mounting frame 204 is slidably connected to the outer wall of the limit rod 10 .

[0029] The presence of the limiting rod 10 provides clear guidance and restriction for the mounting frame 204 during the sliding process, thereby preventing the mounting frame 204 from deflecting or shaking during the sliding process, thereby enhancing the stability of the overall structure.

[0030] See also Figure 1-5 A placement plate 3 is fixedly installed on the top of the base 1, and a plurality of installation grooves 11 are opened on the two clamping plates 205.

[0031] The placement plate 3 supports the LCM module, and the mounting groove 11 can prevent the LCM module from moving. The advantages of the mounting groove 11 are its accuracy and stability. Through the precise hole design, the LCM module can be ensured to maintain an accurate position in the vertical direction, and the displacement deviation can be effectively reduced even during vibration. This not only improves the accuracy of the test, but also helps to better observe and record the test situation.

[0032] See also Figure 1-5 The inner wall of the mounting groove 11 is provided with a rubber pad, and the two clamping plates 205 are symmetrically arranged.

[0033] The rubber pad on the inner wall of the mounting groove 11 can effectively reduce the vibration and noise generated by the device during operation. The rubber pad can not only reduce vibration and noise, but also play a buffering and protective role. When the LCM module is impacted or subjected to external force, the rubber pad can reduce the direct effect of the impact force on the device and reduce the risk of damage to the LCM module.

[0034] See also Figure 1-5 The top end of the rotating rod 201 is rotatably connected to the bottom of the placing plate 3 , and the bottom end of the rotating rod 201 is rotatably connected to the inner bottom of the base 1 .

[0035] The design of the rotating rod 201 ensures the stability of the structure while maintaining flexibility. The rotating connection between the rotating rod 201, the placement plate 3 and the base 1 is reasonably designed and manufactured to withstand a certain load and torque, thereby ensuring the stability of the overall structure.

[0036] The base 1 is in a semi-closed state, and the bottom is in a closed state.

[0037] See also Figure 4 A gear 8 is fixedly installed on the outer wall of the rotating rod 201, and the gear 8 is meshed with a rack 7. A slider 6 is fixedly installed on one side of the rack 7. A threaded rod 5 is provided on one side of the base 1, and the slider 6 is threadedly connected to the outer wall of the threaded rod 5.

[0038] The user holds the turning handle 4 and then drives the threaded rod 5 to rotate, and then the slider 6 performs a translational movement on the outer wall of the threaded rod 5. When the slider 6 moves, it will drive the rack 7 to slide on the outer wall of the gear 8. The rack 7 and the gear 8 are meshed with each other. The sliding of the rack 7 will drive the gear 8 and the turning rod 201 to rotate. The mounting frame 204 and the clamping plate 205 move to a certain extent to stop the rotation of the threaded rod 5. If the friction coefficient between the threaded rod 5 and the slider 6 is high, the slider 6 is not easy to slide when the threaded rod 5 is not subjected to the rotational force. The threaded rod 5 and the slider 6 can make it difficult for the clamping plate 205 to loosen when clamping the LCM module, and at the same time, it can be better adjusted according to the size of the LCM module.

[0039] See also Figure 1-4 A turning handle 4 is fixedly installed at one end of the threaded rod 5, and two mounting plates 9 are fixedly installed on one side of the base 1, and the threaded rod 5 is rotatably connected to the mounting plates 9.

[0040] The design of the turning handle 4 allows the operator to easily turn the threaded rod 5 without the use of additional tools or equipment. The threaded rod 5 is rotatably connected to the base 1 through the mounting plate 9. This connection method ensures the stability of the threaded rod 5 during the rotation process. The mounting plate 9 provides a solid support, so that the threaded rod 5 is not easy to shake or deform when subjected to force, thereby ensuring the stability of the overall structure.

[0041] See also Figure 1-4 A guide rod 13 is fixedly mounted on the inner wall of the base 1 , and the rack 7 is slidably connected to the outer wall of the guide rod 13 .

[0042] The existence of the guide rod 13 can ensure the accuracy and stability of the rack 7 during the movement. Due to the guiding effect of the guide rod 13, the rack 7 can slide smoothly along a predetermined track, avoiding problems caused by position deviation or shaking.

[0043] Working principle: When rotating the rotating rod 201, the rotating rod 201 will drive the two connecting rods 202 to rotate synchronously, and the connecting rod 202 will drive one end of the connecting rod 203 to move toward the two sides of the base 1. The angle between the connecting rod 202 and the connecting rod 203 gradually decreases. The connecting rod 202 drives the mounting frame 204 and the clamping plate 205 to move toward each other through the connecting rod 203. After the two clamping plates 205 run to the width between them, the LCM module is placed in the mounting groove 11, and then the rotating rod 201 is rotated to further fix and clamp the LCM module, and then a vibration test is performed. When clamping and fixing the LCM module, the clamping plates 205 do not need to be fixed one by one, and the clamping assembly 2 will be more convenient for clamping the LCM module, and the clamping work efficiency will be higher.

[0044] The user holds the turning handle 4 and then drives the threaded rod 5 to rotate, and then the slider 6 performs a translational movement on the outer wall of the threaded rod 5. When the slider 6 moves, it will drive the rack 7 to slide on the outer wall of the gear 8. The rack 7 and the gear 8 are meshed with each other. The sliding of the rack 7 will drive the gear 8 and the turning rod 201 to rotate. The mounting frame 204 and the clamping plate 205 move to a certain extent to stop the rotation of the threaded rod 5. If the friction coefficient between the threaded rod 5 and the slider 6 is high, the slider 6 is not easy to slide when the threaded rod 5 is not subjected to the rotational force. The threaded rod 5 and the slider 6 can make it difficult for the clamping plate 205 to loosen when clamping the LCM module, and at the same time, it can be better adjusted according to the size of the LCM module.
