Description

Technical Field

[0001] This utility model belongs to the field of filter testing technology, and in particular relates to a filter testing device. Background Technology

[0002] A filter is a filtering circuit composed of capacitors, inductors, and resistors. A filter can effectively filter out specific frequencies or frequencies outside of a power supply line to obtain a power signal of a specific frequency, or eliminate a power signal of a specific frequency.

[0003] When testing filters, they need to be clamped and fixed on the test platform to prevent them from moving during the test and affecting the test results. However, existing testing equipment often clamps the filters with excessive force, which can damage the filter surface or even deform and damage the filter housing.

[0004] To address these issues, we provide a filter testing device. Utility Model Content

[0005] The purpose of this invention is to provide a filter testing device that uses a buffer spring on the rear side to buffer the force generated when clamping the filter, thereby avoiding excessive clamping force and solving the problem of filter surface damage caused by excessive clamping force.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a filter testing device, including a fixing component, including a base, a vertical plate fixed to the rear side of the base, a driving component fixed to the vertical plate, and a T-shaped groove opened on the base.

[0008] The clamping component includes a power assembly disposed inside the base, a buffer assembly disposed on top of the power assembly, a bearing assembly disposed inside the buffer assembly, and a contact assembly disposed inside the bearing assembly.

[0009] The present invention is further configured such that the power assembly includes a T-shaped block sliding inside the T-slot, an L-shaped plate fixed to the top of the T-shaped block, fixing blocks fixed to both sides of the top of the base, a bidirectional threaded rod disposed inside the fixing block, and a handle fixed to the end of the bidirectional threaded rod.

[0010] The present invention is further configured such that the buffer assembly includes a clamping block fixed to the top of the L-shaped plate, large sliding grooves opened on both sides inside the clamping block, a guide rod fixed inside the sliding groove, a reset spring sleeved outside the guide rod, and a buffer spring disposed inside the clamping block.

[0011] The present invention is further configured such that the bearing component includes a slider sleeved on the outer wall of the guide rod, a movable plate disposed on the opposite side of the slider, and a receiving space opened inside the movable plate.

[0012] The present invention is further configured such that the contact assembly includes an airbag disposed inside the accommodating space, a contact block disposed on the side wall of the airbag, and a flexible plate fixed to the end of the contact block.

[0013] The present invention is further configured such that the inner wall of the fixing block is rotatably connected to the outer wall of the bidirectional threaded rod, and the outer wall of the bidirectional threaded rod is threadedly connected to the inner wall of the L-shaped plate.

[0014] The present invention is further configured such that the inner wall of the slider is slidably connected to the outer wall of the guide rod, and the end of the slider is fixedly connected to the end of the return spring.

[0015] The present invention is further configured to include a buffer component, which includes a connecting plate fixed to the end of the driving member, a moving rod sleeved on the inner wall of the connecting plate, a test piece fixed to the end of the moving rod, a stop plate fixed to the other end of the moving rod, and a connecting spring disposed between the connecting plate and the stop plate.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model uses a rotating handle to drive a bidirectional threaded rod to rotate. As the bidirectional threaded rod rotates, it drives the L-shaped plate to move, thereby clamping the filter. In addition, when the filter comes into contact with the flexible plate, it will compress the buffer spring, generating a force to buffer the impact force generated by clamping the filter and prevent excessive clamping force from damaging the filter.

[0018] 2. This utility model provides a movable rod at the top of the test piece and uses a connecting spring sleeved on the outer wall of the movable rod to buffer the impact force generated when the test piece moves downward, thereby reducing the impact of the test piece on the filter and preventing damage to the filter.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1, please refer to Figure 1-4 The present invention is a filter testing device, including a fixing component 100, including a base 101, a vertical plate 102 fixed to the rear side of the base 101, a driving component 103 fixed on the vertical plate 102, and a T-slot 104 opened on the base 101.

[0030] The clamping component 200, the power component 201 disposed inside the base 101, the buffer component 202 disposed on the top of the power component 201, the bearing component 203 disposed inside the buffer component 202, and the contact component 204 disposed inside the bearing component 203.

[0031] Specifically, the power assembly 201 includes a T-shaped block 201a that slides inside the T-slot 104, an L-shaped plate 201b fixed to the top of the T-shaped block 201a, fixing blocks 201c fixed to both sides of the top of the base 101, a bidirectional threaded rod 201d disposed inside the fixing block 201c, and a handle 201e fixed to the end of the bidirectional threaded rod 201d. The buffer assembly 202 includes a clamping block 202a fixed to the top of the L-shaped plate 201b, a sliding groove 202b with large openings on both sides inside the clamping block 202a, a guide rod 202c fixed inside the sliding groove 202b, a return spring 202d sleeved outside the guide rod 202c, and a buffer spring 202e disposed inside the clamping block 202a.

[0032] Furthermore, the bearing assembly 203 includes a slider 203a sleeved on the outer wall of the guide rod 202c, a movable plate 203b disposed on the opposite side of the slider 203a, and a receiving space 203c opened inside the movable plate 203b. The contact assembly 204 includes an airbag 204a disposed inside the receiving space 203c, a contact block 204b disposed on the side wall of the airbag 204a, and a flexible plate 204c fixed to the end of the contact block 204b. The inner wall of the fixed block 201c is rotatably connected to the outer wall of the bidirectional threaded rod 201d. The outer wall of the bidirectional threaded rod 201d is threadedly connected to the inner wall of the L-shaped plate 201b. The inner wall of the slider 203a is slidably connected to the outer wall of the guide rod 202c. The end of the slider 203a is fixedly connected to the end of the return spring 202d.

[0033] The operation process of this embodiment is as follows: First, rotate the handle 201e. As the handle 201e rotates, the L-shaped plate 201b will move relative to it. As the L-shaped plate 201b moves, the clamping block 202a will move, thereby clamping the filter. In addition, during the process of the clamping block 202a contacting the filter, the clamping block 202a will compress the buffer spring 202e. At this time, the buffer spring 202e will generate a reaction force to buffer the impact force generated by clamping the filter, preventing the filter from being damaged by excessive clamping force. In addition, during the process of clamping the filter, the flexible plate 204c will first contact the filter to achieve soft contact between the flexible plate 204c and the filter. Furthermore, when the flexible plate 204c is squeezed by the filter, the airbag 204a is squeezed, and the gas inside it slowly flows out, further buffering the filter and preventing damage to the filter.

[0034] Example 2, please refer to Figure 1 and Figure 5 Based on Embodiment 1, it also includes a buffer component 300, which includes a connecting plate 301 fixed to the end of the driving component 103, a moving rod 302 sleeved on the inner wall of the connecting plate 301, a test piece 305 fixed to the end of the moving rod 302, a stop plate 303 fixed to the other end of the moving rod 302, and a connecting spring 304 disposed between the connecting plate 301 and the stop plate 303.

[0035] The operation process of this embodiment is as follows: First, the driving component 103 is activated to move the test component 305 downward to test the filter. In addition, when the test component 305 contacts the filter, the test component 305 will push up the moving rod 302. At this time, the connecting spring 304 is compressed, generating a force that is opposite to the direction of the pressure of the test component 305 testing the filter, thereby buffering the pressure and preventing the filter from being damaged.
