Description

Technical Field

[0001] The utility model relates to a sensor with a protection function, in particular to a sensor with a protection function applied to the technical field of sensors. Background Art

[0002] A pressure sensor is one of the most commonly used sensors in industrial practice. It is widely used in various industrial automatic control environments, involving many industries such as water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military, petrochemical, oil wells, electric power, ships, machine tools, pipelines, etc.

[0003] The specification of Chinese Patent CN220542298U discloses a pressure sensor, including an outer housing; a sensor body is provided at the bottom of the outer housing; a plurality of fixing blocks are fixedly connected to the side wall of the outer housing; the plurality of fixing blocks are evenly distributed on the side wall of the outer housing; during use, the fixing column is inserted into the side wall of the sliding groove, and after the fixing column is completely inserted into the side wall of the sliding groove, the inserting block is pushed into the side wall of the slot to make it stuck. When it is necessary to disassemble the sensor body, hold the pull rod and pull it, and then the sensor body can be disassembled. In this process, it reduces that the existing sensor body and the outer housing are connected by threads, which may cause rust or slipping of the threads during long-term use, resulting in difficulty in disassembling the sensor body. At this time, by inserting the inserting block into the side wall of the slot, the convenience of disassembling and installing the sensor body is improved.

[0004] Currently, the outside of the pressure sensor lacks a corresponding protection mechanism. When it is impacted, it is easy to cause the sensor to deform or even be damaged, affecting the normal use of the sensor and resulting in insufficient practicality. Summary of the Utility Model

[0005] Aiming at the above-mentioned prior art, the technical problem to be solved by the present utility model is that the outside of the pressure sensor lacks a corresponding protection mechanism. When it is impacted, it is easy to cause the sensor to deform or even be damaged, affecting the normal use of the sensor and resulting in insufficient practicality.

[0006] To solve the above problems, the present utility model provides a sensor with a protection function, including a sensor body. A sleeve is sleeved on the surface of the sensor body. An inner layer cover is detachably connected to the outside of the sleeve. Inner grooves are symmetrically drilled on the side wall of the sleeve. Compression springs are fixedly connected in the inner grooves. One end of the compression spring close to the groove opening is fixedly connected with a buckle. Limiting holes corresponding to the inner grooves are drilled on the side wall of the inner layer cover, and the buckle is engaged with the limiting holes. A plurality of shock-absorbing springs are annularly and equidistantly installed on the outer wall of the inner layer cover. Four outer layer covers are annularly and equidistantly sleeved outside the shock-absorbing springs, and the inner wall of the outer layer cover is connected to the shock-absorbing springs.

[0007] In the above-mentioned sensor, when an impact occurs in an emergency, the sensor body can be effectively buffered and protected multiple times.

[0008] As a further improvement of this application, a plurality of card slots are equidistantly drilled in the outer wall in a circular shape, and telescopic rods are fixedly connected in the card slots.

[0009] As a further improvement of this application, one end of the shock-absorbing spring close to the card slot is fixedly connected with a threaded shaft, and the threaded shaft is sleeved outside the telescopic rod and engaged with the card slot.

[0010] As a further improvement of this application, one end of the shock-absorbing spring away from the threaded shaft is fixedly connected with a block with a groove, and a handle is fixedly connected to one end of the block away from the shock-absorbing spring.

[0011] As another improvement of this application, screw holes corresponding to the card slots are drilled on the side walls of the outer layer cover, and the block is threadedly connected with the screw holes and engaged with the telescopic rod.

[0012] As a supplement to another improvement of this application, the thickness of the block is equal to the inner wall thickness of the screw hole, and there is a gap between adjacent outer layer covers.

[0013] As a supplement to another improvement of this application, the side wall thickness of the card sleeve is more than twice the thickness of the rear wall of the side wall of the inner layer cover.

[0014] In summary, this solution can achieve: when the sensor body encounters an impact in an emergency during use, when installing the sensor body, the card sleeve can be sleeved on the sensor body and fixed in advance, and then press the two buckles at the same time to retract them into the inner groove. At this time, the inner layer cover is sleeved on the surface and the position is adjusted by sliding. When the buckle coincides with the limit hole, it will automatically spring into the limit hole and be engaged and fixed through the compression spring, so as to install the inner layer cover and the outer layer cover. At this time, in case of impact, the outermost outer layer cover can be used to protect it, and the pressure generated by the outer layer cover during the impact can be used to buffer and shock-absorb the sensor body inside through the shock-absorbing spring. And there is a gap between adjacent outer layer covers, so that the outer layer covers will not collide with each other when the shock-absorbing spring and the telescopic rod expand and contract. After the initial protection of the outer layer cover, the inner layer cover can be used for secondary protection again, providing double protection for the sensor body in case of damage under a large impact, avoiding its being damaged by the impact, and effectively achieving the effect of multiple buffer protections for the sensor body when an impact occurs in an emergency.

[0024] The following will make a detailed description of the two embodiments of this application with reference to the accompanying drawings.

[0025] The first embodiment:

[0026] Figures 1-5 Show a sensor with a protection function, including a sensor body 1. A ferrule 6 is sleeved on the surface of the sensor body 1. An inner cover 2 is detachably connected to the outside of the ferrule 6. Inner grooves 9 are symmetrically drilled on the side wall of the ferrule 6. A compression spring 10 is fixedly connected in the inner groove 9. One end of the compression spring 10 close to the notch is fixedly connected with a snap 8. Limit holes 7 corresponding to the inner grooves 9 are drilled on the side wall of the inner cover 2, and the snap 8 is engaged with the limit holes 7. A plurality of shock-absorbing springs 3 are annularly and equidistantly installed on the outer wall of the inner cover 2. Four outer covers 4 are annularly and equidistantly sleeved outside the shock-absorbing springs 3, and the inner wall of the outer cover 4 is connected to the shock-absorbing springs 3. The thickness of the side wall of the ferrule 6 is more than twice the thickness of the rear wall of the side wall of the inner cover 2. A plurality of card slots 5 are annularly and equidistantly drilled on the outer wall, and a telescopic rod 15 is fixedly connected in the card slots 5.

[0027] This solution can achieve the following: When the sensor body 1 encounters a sudden impact during use, the ferrule 6 can be sleeved on the sensor body 1 and fixed in advance during the installation of the sensor body 1. Then, by pressing two buckles 8 simultaneously, they can be retracted into the inner groove 9. At this time, the inner layer cover 2 is sleeved on the surface and its position is adjusted by sliding. When the buckle 8 coincides with the limit hole 7, it will automatically spring into the limit hole 7 by the compression spring 10 for clamping and fixing, so as to install the inner layer cover 2 and the outer layer cover 4. At this time, in case of impact, the outermost outer layer cover 4 can protect it. And the pressure generated by the outer layer cover 4 during the impact can be buffered by the shock-absorbing spring 3 for the sensor body 1 inside it. There is a gap between two adjacent outer layer covers 4, so that the outer layer covers 4 will not collide with each other when the shock-absorbing spring 3 and the telescopic rod 15 perform telescopic activities. After the preliminary protection of the outer layer cover 4, the inner layer cover 2 can be used for secondary protection again, providing double protection for the sensor body to prevent it from being damaged by the impact, effectively achieving the effect of multiple buffer protections for the sensor body 1 in case of impact in case of sudden situations.

[0028] The second implementation mode:

[0029] Figures 2-3 and Figure 7 It is shown that one end of the shock-absorbing spring 3 close to the clamping groove 5 is fixedly connected with a threaded shaft 14, and the threaded shaft 14 is sleeved outside the telescopic rod 15 and is engaged with the clamping groove 5. One end of the shock-absorbing spring 3 far from the threaded shaft 14 is fixedly connected with a block 13 with a groove. One end of the block 13 far from the shock-absorbing spring 3 is fixedly connected with a handle 11. Threaded holes 12 corresponding to the clamping grooves 5 are drilled on the side walls of the outer layer cover 4, and the block 13 is threadedly connected with the threaded holes 12, and the block 13 is engaged with the telescopic rod 15. The thickness of the block 13 is equal to the inner wall thickness of the threaded hole 12, and there is a gap between two adjacent outer layer covers 4.

[0030] This solution can achieve the following: If the outer layer cover 4 on the outside is damaged due to long-term use, the handle 11 can be held to twist the block 13 and take it out of the threaded hole 12. Then, the outer layer cover 4 can be taken off. And since the outer layer cover 4 is formed by a combination of multiple parts, it can be selectively removed and replaced according to the damaged part. The new outer layer cover 4 is clamped on the shock-absorbing spring 3 and then fixedly connected by threading the block 13 with the threaded hole 12, so that the groove is engaged with the convex block, thereby fixing the outer layer cover 4, effectively achieving the effect of convenient disassembly and replacement of the outer layer cover 4.

[0031] Combined with the current actual requirements, the above implementation modes adopted in this application, the scope of protection is not limited to this. Within the knowledge scope of those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of this utility model.
