Description

Technical Field

[0001] This utility model relates to the field of electronic testing technology, and in particular to a quick-release radio frequency anti-interference test probe clamping mechanism. Background Technology

[0002] With the continuous development of industrial testing technology, higher requirements have been placed on the precise positioning and stable clamping of test probes in fields such as material performance testing and non-destructive testing. From ensuring that the probe is in close contact with the test surface during manual ultrasonic testing to maintaining a specific position and angle of the probe during eddy current testing.

[0003] The test probe clamping mechanism mainly consists of a base, a positioning component, and a clamping component. The base provides support, the positioning component ensures that the probe is accurately positioned, and the clamping component achieves stable clamping through mechanical or hydraulic devices. During operation, the probe is first placed into the positioning slot, and after adjusting the position, the clamping component applies pressure to firmly fix the probe and meet the testing requirements.

[0004] With the continuous miniaturization and integration of electronic devices, radio frequency interference testing places higher demands on the adaptability and operational efficiency of test probes. However, existing interference test probe clamping mechanisms generally suffer from fixed structures and cumbersome disassembly and assembly, making it difficult to quickly switch between different specifications of test probes. This not only affects testing efficiency but also limits the expansion of testing scenarios. To address these issues, a quick-release radio frequency interference test probe clamping mechanism is proposed. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a quick-release RF anti-interference test probe clamping mechanism, which aims to improve the problem of the lack of a quick-release structure for the test head in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A quick-release RF anti-interference test probe clamping mechanism includes a housing and a detection head. The housing has a clamping assembly inside and a fixed box is fixedly connected to the outside of the housing. The fixed box has two sliding blocks inside and two limiting plates fixedly connected to the outside of the two moving blocks. Telescopic columns are fixedly connected to the opposite sides of the two moving blocks, and springs are sleeved on the outside of the two telescopic columns.

[0008] As a further description of the above technical solution:

[0009] The outer side of the fixing box is provided with a sliding groove, and the outer side of the limiting plate is slidably connected to the inside of the sliding groove;

Two transmission rods are rotatably connected to the upper and lower ends of the push block. A sliding block is rotatably connected to the opposite side of each of the two transmission rods. A clamping plate is fixedly connected to the rear end of the sliding block. A limiting post is fixedly connected to the inside of the housing.

[0016] As a further description of the above technical solution:

[0017] The sliding block has a sliding groove on its outside, and the limiting post is slidably connected to the inside of the sliding groove.

[0018] As a further description of the above technical solution:

[0019] The driving end of the cylinder is fixedly connected to the front end of the push block, and the two sliding blocks are slidably connected to the inside of the housing.

[0020] As a further description of the above technical solution:

[0021] A rubber pad is fixedly connected to the outside of the clamping plate, and the adjacent side of the two limiting plates is in contact with the outside of the detection head.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, when detecting objects in different directions, the operator takes out the detection head, and the limiting plate opens under force, making it easy to take out. When installing a new detection head, it is inserted between the limiting plates, and the limiting plate drives the moving block to slide, making room for the detection head to slide in.

[0031] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 and Figure 4This utility model provides an embodiment of a quick-release RF anti-interference test probe clamping mechanism, including a housing 1 and a detection head 15. The housing 1 is equipped with a clamping assembly inside. The housing 1 serves as the main frame of the entire clamping mechanism, protecting the internal components and providing a mounting base, thus providing stable structural support for subsequent operations. A fixing box 10 is fixedly connected to the outside of the housing 1. Two moving blocks 11 are slidably connected inside the fixing box 10. The sliding of the moving blocks 11 within the fixing box 10 is a key action component for realizing the quick release of the detection head 15. The moving blocks 11 can move accordingly according to the installation and disassembly requirements of the detection head 15. A limiting plate 12 is fixedly connected to the outside of both moving blocks 11. The limiting plate 12 is mainly used to limit and fix the position of the detection head 15, ensuring that the detection head 15 remains stable during the testing process and does not easily shake or shift.

[0033] Telescopic columns 13 are fixedly connected to the opposite sides of the two movable blocks 11. The telescopic columns 13 can provide a certain degree of expansion and contraction buffer when the movable blocks 11 move, and also help limit the movement direction of the movable blocks 11 to make them more stable. Springs 14 are sleeved on the outside of the two telescopic columns 13. The springs 14 are key components that provide elastic force. The springs 14 play the role of pushing and resetting the movable blocks 11 during the installation and removal of the detection head 15. The outside of the fixed box 10 is provided with a sliding groove. The outside of the limiting plate 12 is slidably connected to the inside of the sliding groove. The sliding groove provides a track for the sliding of the limiting plate 12, so that the limiting plate 12 can slide along the fixed groove. The movement path ensures the stability and reliability of the structure. One end of the spring 14 is fixedly connected to the inside of the fixed box 10, and the other end of the spring 14 is fixedly connected to the top of the moving block 11. This connection method allows the spring 14 to effectively apply force to the moving block 11. The top of the telescopic column 13 is fixedly connected to the inside of the fixed box 10, which further ensures the stability of the telescopic column 13 and its supporting role for the moving block 11. The outer side of the limiting plate 12 is arc-shaped. The arc-shaped design can better fit the outer contour of the detection head 15, increase the contact area with the detection head 15, and thus improve the fixing effect of the detection head 15.

[0034] Reference Figures 1 to 3The clamping assembly includes a push block 3, which is an important component for transmitting power. The push block 3 moves under the drive of the cylinder 9, thereby driving the subsequent components to move. The push block 3 is externally slidably connected to the inside of the housing 1. Sliding inside the housing 1 ensures that the push block 3 moves in a fixed direction and avoids deviation. The front end of the housing 1 is fixedly connected to the cylinder 9, which serves as the power source for the entire clamping assembly and provides a stable and controllable driving force to drive the movement of the push block 3. The upper and lower ends of the push block 3 are rotatably connected to two transmission rods 5. The transmission rods 5 play the role of transmitting and converting power, converting the linear motion of the push block 3 into the lateral sliding of the sliding block 2. The two transmission rods 5 are rotatably connected to the opposite sides of each other. The sliding block 2 slides inside the housing 1 under the drive of the transmission rods 5 and is the direct action component for clamping the cable. The rear end of the sliding block 2 is fixedly connected to a clamping plate 7, which is used to directly contact and clamp the cable and is a key structure for fixing the cable.

[0035] A limiting post 6 is fixedly connected inside the housing 1. The limiting post 6 precisely limits the sliding direction and distance of the sliding block 2, ensuring that the clamping plate 7 can accurately clamp the cable. A sliding groove 4 is opened on the outside of the sliding block 2. The external of the limiting post 6 is slidably connected to the inside of the sliding groove 4. The sliding groove 4 and the limiting post 6 cooperate with each other to further ensure the accuracy of the sliding trajectory of the sliding block 2. The driving end of the cylinder 9 is fixedly connected to the front end of the push block 3. This connection method can ensure that the driving force of the cylinder 9 is effectively transmitted to the push block 3. The external of the two sliding blocks 2 is slidably connected to the inside of the housing 1. The sliding inside the housing 1 allows the sliding blocks 2 to move stably. A rubber pad 8 is fixedly connected to the outside of the clamping plate 7. The rubber pad 8 increases the friction between the clamping plate 7 and the cable, and also provides a certain degree of protection for the cable to avoid damage during clamping. The adjacent side of the two limiting plates 12 contacts the outside of the detection head 15. Through this contact, the detection head 15 is fixed and positioned.

[0036] Working principle: When the processing personnel need to test the electronic equipment, they place the housing 1 on the cable of the device to be tested, and then start the cylinder 9. The cylinder 9 will drive the push block 3 to move inside the housing 1, so that the two transmission rods 5 pull the sliding block 2 to slide inside the housing 1. When the sliding block 2 slides, the limiting post 6 will limit the sliding direction and distance of the sliding block 2 until the clamping plate 7 and the rubber pad 8 clamp and fix the cable. At this time, it can be ensured that the detection head 15 has stable contact with the cable, ensuring stable testing.

[0037] When it is necessary to detect objects in different directions, the operator can replace different detection heads 15 and remove the detection head 15 from inside the two limiting plates 12. At this time, the two limiting plates 12 will be subjected to force and open to both sides until the detection head 15 is successfully removed. When a new detection head 15 needs to be installed, the outside of the detection head 15 is inserted back into the adjacent side of the two limiting plates 12. The two limiting plates 12 will drive the moving block 11 to slide in opposite directions in the fixing box 10, thereby allowing the detection head 15 to slide in normally. When the detection head 15 slides to the center position inside the two limiting plates 12, the two springs 14 will continuously push the moving block 11 to slide, thereby restricting the position of the detection head 15 by the two limiting plates 12, thus achieving the installation effect. By quickly installing and removing the detection head 15, the detection efficiency is improved, and it can adapt to detection heads 15 of different sizes, thereby increasing the detection range.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
