Description

Technical Field

[0001] This utility model relates to the field of probe protective sleeves, and in particular to a retractable probe protective sleeve. Background Technology

[0002] A probe is a device or component that can sense specific physical, chemical, or biological quantities and convert them into detectable signals. It is often used as the front-end sensing unit of detection and measurement equipment and is widely used in industrial detection, medical diagnosis, environmental monitoring, security monitoring and other fields. Its core function is to collect the characteristic information of the target object and convert non-electrical signals into electrical signals or other easily transmitted and processed signals for subsequent equipment analysis and judgment.

[0003] Existing probe protective sleeves mainly focus on physical protection to protect the probe. In terms of physical impact and wear prevention, the protective sleeve uses a rigid shell such as stainless steel or hard plastic to form a rigid barrier, combined with elastic buffer layers such as silicone or sponge to absorb impact, and is also coated with wear-resistant coatings such as polytetrafluoroethylene to reduce scratches and wear, thereby avoiding mechanical damage to the probe during installation, use and movement.

[0004] Existing probe protective sleeves mostly adopt an integrated fixed structure or a single-length protective shell design. Their protection range and protection position are all preset and fixed, and they cannot be extended and adjusted according to the actual parts of the probe that need protection. Furthermore, the fixed protective structure can only protect a specific single area, making it difficult to provide precise protection for different length areas of the probe. Therefore, a retractable probe protective sleeve is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a retractable probe protective sleeve, which aims to improve the problems of existing probe protective sleeves that use an integrated fixed structure or a single-length protective shell, making it difficult to adjust the protection range and position according to the actual needs of the probe, achieve precise protection for different length areas of the probe, and adapt to the diverse protection needs of the probe.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a retractable probe protective sleeve, including a probe, the probe's outer wall being provided with a retractable protective mechanism and a disassembly mechanism, the retractable protective mechanism including a retractable protective outer shell, a retractable protective inner shell slidably connected to the inner wall of the retractable protective outer shell, a support ring shell fixedly connected to the left side of the retractable protective inner shell, a rotating ring shell rotatably connected to the inner wall of the support ring shell, an arc-shaped groove being formed on the inner wall of the rotating ring shell, a limiting groove being formed on the inner wall of the support ring shell, a moving block being slidably connected to the inner wall of the limiting groove, the left outer wall of the moving block being slidably connected to the inner wall of the arc-shaped groove, an anti-slip clamping block being fixedly connected to the left side of the moving block, and a limiting toothed ring being fixedly connected to the outer wall of the rotating ring shell.

[0007] As a further description of the above technical solution: The telescopic protective mechanism also includes a limiting rod, both ends of which are fixedly connected to the inner wall of the support ring shell.

[0008] As a further description of the above technical solution: The telescopic protective mechanism also includes a limiting tooth block, the inner wall of which is slidably connected to the outer wall of the limiting rod.

[0009] As a further description of the above technical solution: The telescopic protective mechanism also includes a spring, and the right side of the limiting tooth block is elastically connected to the inner wall of the support ring shell through the spring.

[0010] As a further description of the above technical solution: One end of the spring is fixedly connected to the inner wall of the support ring shell, and the other end of the spring is fixedly connected to the right side of the limiting tooth block.

[0011] As a further description of the above technical solution: The disassembly mechanism includes a threaded connecting sleeve, the outer wall of which is fixedly connected to the inner wall of the telescopic protective shell.

[0012] As a further description of the above technical solution: The disassembly mechanism also includes a threaded connector, the outer wall of which is fixedly connected to the right end of the probe.

[0013] As a further description of the above technical solution: The telescopic protective shell is detachably connected to the probe via a threaded connecting sleeve and a threaded connecting head.

[0014] This utility model has the following beneficial effects: 1. In this utility model, by setting a telescopic protective mechanism, the telescopic protective inner shell can be pulled to slide on the inner wall of the telescopic protective outer shell, and the telescopic adjustment can be made according to the actual position that the probe needs to be protected. This breaks the limitation of the fixed protective structure and can achieve precise protection for different length areas of the probe, adapting to the diverse protection needs of the probe.

[0015] 2. In this utility model, the rotating ring shell is used to squeeze the anti-slip clamping block to hold the outer wall of the probe. Then, the rotating ring shell is locked by the meshing of the limiting tooth block and the limiting tooth ring. The positioning of the telescopic protective inner shell is achieved by using friction. The entire adjustment and locking process is clear and the structure is stable after locking, which can prevent the protective shell from shifting during use and ensure the protective effect.

[0018] 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.

[0019] Reference Figures 1-3This utility model provides an embodiment of a retractable probe protective sleeve, including a probe 1. The outer wall of the probe 1 is provided with a telescopic protective mechanism 2 and a disassembly mechanism 3. The telescopic protective mechanism 2 includes a telescopic protective outer shell 211, which is the main protective structure, providing basic protection and sliding support for a telescopic protective inner shell 212. A telescopic protective inner shell 212 is slidably connected to the inner wall of the telescopic protective outer shell 211, allowing the inner shell 212 to slide along the inner wall of the telescopic protective outer shell 211, thus adjusting the protective length. A support ring shell 213 is fixedly connected to the left side of the telescopic protective inner shell 212. The support ring shell 213 supports components such as a rotating ring shell 214 and a limiting rod 220, providing structural support. A rotating ring shell 214 is rotatably connected to the inner wall of the support ring shell 213, allowing the rotating ring shell 214 to rotate within the support ring shell 213. The rotating ring shell 214 is driven to move by an arc-shaped groove 215, thus driving the moving block 217 to move. An arc-shaped groove 215 is formed on the inner wall of shell 214. The arc-shaped groove 215 is an inclined groove structure. Through sliding cooperation with the moving block 217, it drives the moving block 217 to move along the limiting groove 216. The supporting ring shell 213 has a limiting groove 216 on its inner wall. The limiting groove 216 restricts the movement direction of the moving block 217 to ensure that it slides in a straight line. The moving block 217 is slidably connected to the inner wall of the limiting groove 216. The moving block 217 is used to transmit the pressing force of the arc-shaped groove 215 and drive the anti-slip mechanism. The clamping block 218 moves closer to or further away from the probe 1. The outer left wall of the moving block 217 is slidably connected to the inner wall of the arc groove 215. The left side of the moving block 217 is fixedly connected to the anti-slip clamping block 218. The anti-slip clamping block 218 can fit against the outer wall of the probe 1. The positioning of the telescopic protective inner shell 212 is achieved through friction. The outer wall of the rotating ring shell 214 is fixedly connected to the limiting toothed ring 219. The limiting toothed ring 219 can mesh with the limiting toothed block 221 to achieve rotational limitation of the rotating ring shell 214.

[0020] Reference Figures 4-7 The telescopic protective mechanism 2 also includes a limiting rod 220, which provides guidance for the sliding of the limiting tooth block 221 and restricts its movement trajectory. Both ends of the limiting rod 220 are fixedly connected to the inner wall of the support ring shell 213. The telescopic protective mechanism 2 also includes a limiting tooth block 221, which can slide along the limiting rod 220. The locking and unlocking of the rotating ring shell 214 is achieved by engaging or disengaging with the limiting tooth ring 219. The inner wall of the limiting tooth block 221 is slidably connected to the outer wall of the limiting rod 220. The telescopic protective mechanism 2 also includes a spring 222, which provides a rebound force for the limiting tooth block 221, so that it is normally engaged with the limiting tooth ring 219. The right side of the limiting tooth block 221 is elastically connected to the inner wall of the support ring shell 213 through the spring 222. One end of the spring 222 is fixedly connected to the inner wall of the support ring shell 213, and the other end of the spring 222 is fixedly connected to the right side of the limiting tooth block 221.

[0021] Reference Figure 2The disassembly mechanism 3 includes a threaded connecting sleeve 311, which is used to cooperate with a threaded connecting head 312 to realize the detachable connection between the telescopic protective shell 211 and the probe 1. The outer wall of the threaded connecting sleeve 311 is fixedly connected to the inner wall of the telescopic protective shell 211. The disassembly mechanism 3 also includes a threaded connecting head 312, which is threadedly engaged with the threaded connecting sleeve 311 to provide a connection structure for the disassembly and assembly of the protective shell. The outer wall of the threaded connecting head 312 is fixedly connected to the right end of the probe 1. The telescopic protective shell 211 is detachably connected to the probe 1 through the threaded connecting sleeve 311 and the threaded connecting head 312.

[0022] Working principle: When probe 1 needs protection, the threaded connecting sleeve 311 can be threadedly connected to the threaded connecting head 312 on probe 1, so that the telescopic protective outer shell 211 and the telescopic protective inner shell 212 protect probe 1. Then, the telescopic protective inner shell 212 can be pulled to slide on the inner wall of the telescopic protective outer shell 211, so that the telescopic extension and retraction can be adjusted according to the position of probe 1 that needs protection. After the adjustment is completed, the limiting tooth block 221 can be moved to slide on the outer wall of the limiting rod 220, so that the spring 222 is compressed, thereby disengaging the limiting tooth block 221 from the limiting tooth ring 219. Then, by rotating the ring shell 214, the rotating ring shell 214 is squeezed by the arc groove 215, causing the four moving blocks 217 to slide on the inner wall of the corresponding limiting groove 216. The four moving blocks 217 then drive the four anti-slip clamps 218 to clamp on the outer wall of the probe 1. Then, the limiting tooth block 221 can be released. Under the action of the spring 222, the limiting tooth block 221 re-engages with the limiting tooth ring 219, so that the rotating ring shell 214 can be limited and locked. Thus, under the action of friction, the telescopic protective inner shell 212 can be positioned in a specified position, and then the telescopic adjustment can be made according to the position of the probe 1 that needs to be protected.

[0023] 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.
