[0003] The commonly used sensor is a vibration sensor, and the function of the vibration sensor is mainly to receive mechanical quantities and convert them into proportional electrical quantities. However, the existing vibration sensor has the risk of obvious bending of the vibration plate when subjected to strong impact. It is easy to accidentally fall to the ground or similar places during transportation or installation, or to be subjected to excessive impact, causing the internal structure to separate, so that the vibration sensor cannot work normally. SUMMARY

[0029] The specific embodiments of the present application are described below in combination with the drawings.

[0030] Embodiment 1:

[0032] The vibration pickup 12 is provided with a first sliding groove and a second sliding groove, the first sliding groove is located between the two second sliding grooves, and the diameter of the first sliding groove is smaller than that of the second sliding groove;

[0033] Elastic rubbers 14 are arranged on the upper and lower sides of the vibration pickup 12, a pressing plate 31 is arranged above the elastic rubber 14 above the vibration pickup 12, a pressing rod 34 is fixedly connected to the pressing plate 31, a pressing mechanism is fixedly connected to the top of the cover 1, and the pressing mechanism is connected with the pressing rod 34.

[0034] The pressing mechanism is used for controlling the downward movement of the pressing plate 31 to extrude the elastic rubber 14, and the pressing mechanism is used for controlling the upward movement of the pressing plate 31 to release the elastic rubber 14;

[0035] The pressing mechanism includes a first auxiliary ladder 15, the first auxiliary ladder 15 is fixedly connected with the cover 1, a fixed tube 36 is fixedly connected inside the first auxiliary ladder 15, auxiliary grooves 35 are formed in the inner walls on the left and right sides of the inner cavity of the fixed tube 36, a screw rod 30 is fixedly connected to the top inner wall of the inner cavity of the fixed tube 36, a second bevel gear 29 is fixedly connected to the screw rod 30, a threaded plate 32 is threadedly connected to the screw rod 30, the threaded plate 32 is slidingly connected with the fixed tube 36, a plurality of connecting rods 33 are fixedly connected to the bottom of the threaded plate 32, the connecting rods 33 are fixedly connected with the pressing rod 34, a rotating rod 3 is arranged through the first auxiliary ladder 15, the rotating rod 3 extends into the fixed tube 36, a first bevel gear 28 is fixedly connected to one end of the rotating rod 3 inside the fixed tube 36, and the first bevel gear 28 and the second bevel gear 29 are engaged;

[0036] When the vibration sensor needs to be used, the rotating rod 3 can be rotated to drive the first bevel gear 28 to rotate, the first bevel gear 28 drives the screw rod 30 to rotate through the second bevel gear 29, the screw rod 30 drives the threaded plate 32 to move downward, the threaded plate 32 drives the pressing rod 34 to move downward through the connecting rods 33, the pressing rod 34 drives the pressing plate 31 to move downward, and the pressing plate 31 moving downward will compress the elastic rubber 14 inside the cover 1. Since the elastic rubber 14 will not provide elasticity after being compressed, the vibration pickup 12, the vibration plates 11, the counterweight column 10 and the piezoelectric bodies 8 will be stably stored inside the cover 1, so as not to affect the normal use thereof;

[0037] When the vibration sensor is not in use, to prevent it from being accidentally dropped or subjected to excessive impact during transportation or installation, which could cause internal structural separation, the rotating rod 3 can be rotated in the reverse direction, causing the pressure rod 34 to move upward. The pressure rod 34 then moves the pressure plate 31 upward, effectively releasing the elastic rubber 14. Because the elastic rubber 14 is elastic, when the vibration sensor is impacted, the internal components such as the counterweight column 10, piezoelectric element 8, and vibrating plate 11 will only fluctuate slightly with the elastic rubber 14, minimizing damage to these components and providing excellent protection.

[0038] Example 2:

[0039] like Figures 1-9 As shown, while all other parts are the same as in Embodiment 1, the difference between this embodiment and Embodiment 1 is that: a telescopic mechanism is fixedly connected to the top of the pressing mechanism, and a bending rod 4 is fixedly connected inside the telescopic mechanism;

[0040] The telescopic mechanism is used to control the distance between the bending rod 4 and the outer cover 1;

[0041] The telescopic mechanism includes a first connecting sleeve 2, which is fixedly connected to a first auxiliary ladder 15.

[0043] The diameter of the cavity at the tail of the first connecting sleeve 2 is smaller than the maximum diameter of the position of the second connecting sleeve 16, so that the second connecting sleeve 16 can be limited, and the second connecting sleeves 16 of different specifications are designed according to this standard;

[0044] The conventional vibration sensor does not have a fixed handle for the user to hold during use, and more often directly uses the connecting wire 13 to directly pull the vibration sensor to move, so that the vibration sensor will randomly shake, increase the probability of damage, and is not conducive to being directly and accurately fixed at a certain point for placement and use.

[0045] The first connecting sleeve 2 and the plurality of second connecting sleeves 16 are arranged to replace the connecting wire 13 and serve as fixed hand poles, when use is needed, the second connecting sleeve 16 can be pulled, and the first limiting groove 17 is formed in the second connecting sleeve 16, when the second connecting sleeve 16 is pulled to the appropriate position, the auxiliary plate 37 can be pressed, the auxiliary plate 37 drives the push rod 47 to move downward, the push rod 47 drives the second limiting head 42 to move downward, the second limiting head 42 moves downward and is clamped with the first limiting groove 17 on the second connecting sleeve, good positioning effect is achieved, and the push rod 47 moves downward and drives the limiting tube 20 and the first limiting head 18 to move downward, the first limiting head 18 is clamped with the second limiting groove 46 under the action of the first spring 21, the second limiting head 42 is positioned, the second connecting sleeve 16 is effectively positioned, and the user is convenient to use.

[0051] When it is needed to use, the sealing plug 27 can be taken off first, and then the protection tube 6 is pressed to extrude the second spring 22, so that the rotating column 24 and the connecting line 13 are exposed, so that the connecting line 13 can be released by rotating the rotating column 24 for use;

[0052] And in normal use, the protection tube 6 and the bending rod 4 can be used as a handle to hold, further facilitating the use of the vibration sensor.
