DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] The following will be combined with Figure 1 - Figure 2 to provide a detailed description of a mechanical vibration switch according to an embodiment of the present utility model.

[0026] Embodiment:

[0027] A mechanical vibration switch provided by an embodiment of the present utility model is referred to Figures 1 to 2As shown in the figure, it includes a mechanical vibration switch body 1. A reset button assembly 2 is provided on the housing of the mechanical vibration switch body 1. The reset button assembly 2 includes a reset rod 3, a protection cylinder 4, and a button cover 5. The reset rod 3 is hermetically and slidably connected to the housing of the mechanical vibration switch body 1. The protection cylinder 4 is fixedly installed on the housing of the mechanical vibration switch body 1 by bolts. The button cover 5 is sleeved with the protection cylinder 4. A retaining ring 6 is fixedly installed at the lower part of the reset rod 3. A return spring 7 is sleeved on the outer part of the upper part of the reset rod 3. A limiting column 8 is fixedly connected to the fixed end of the reset rod 3. The limiting column 8 is adaptively and movably connected to the inner cavity of the protection cylinder 4. In this structure, when a person presses the button cover 5, the button cover 5 will push the limiting column 8 downward, and the limiting column 8 will push the reset rod 3 to squeeze the elastic sheet inside the mechanical vibration switch body 1, so that the elastic sheet returns to its original position, so that the mechanical vibration switch body 1 is reset. Then, the pressure on the button cover 5 is released. At this time, under the elastic force of the return spring 7, the reset rod 3 can return to its original position, which is convenient for the next pressing and resetting;

[0028] In the above structure, the button cover 5 and the protection cylinder 4 form a protection device for the return spring 7, so as to avoid dust accumulation in the area of the return spring 7 in a harsh environment, which may cause the return spring 7 to not be pressed down. At the same time, it can also prevent dust accumulation at the connection between the housing of the mechanical vibration switch body 1 and the reset rod 3, which affects the smooth sliding of the reset rod 3, thereby improving the applicability of the reset button assembly 2 in a harsh environment and the use stability of the reset button assembly 2.

[0029] It should be noted that: the above mechanical vibration switch body 1 is an existing device, and its internal structure includes a housing, an elastic sheet, a micro switch, a measuring rod, a positioning part, etc. The specific internal structure has been disclosed. For details, reference can be made to Patent CN212907546U. And this application does not improve the specific internal structure of the mechanical vibration switch body 1, so it will not be introduced in detail here.

[0030] Reference Figures 1 to 2 As shown in the figure, an external thread 13 is provided on the outer wall of the upper part of the protection cylinder 4, and an internal thread 14 adapted to the external thread 13 is provided on the inner wall of the lower part of the button cover 5. A convex column 9 is fixedly connected to the top end of the limiting column 8. A baffle 10 is fixedly installed at the top end of the convex column 9 by bolts. A partition 11 is constructed inside the button cover 5. A through hole 12 is opened at the center of the partition 11. The convex column 9 passes through the through hole 12. In this structure, after the return spring 7 drives the reset rod 3 to return to its original position, a person rotates the button cover 5 to thread the internal thread 14 on the button cover 5 with the external thread 13 on the protection cylinder 4, so as to lock the relative positions of the protection cylinder 4 and the button cover 5. Thus, during non-use, it can prevent a person from accidentally touching it, and at the same time prevent the reset rod 3 from shaking due to vibration, so as to ensure the stability of the reset button assembly 2;

[0031] Among them, when rotating the button cover 5, the baffle 10 on the convex column 9 and the retaining ring 6 of the reset rod 3 can be used to limit the maximum upward rotation position of the button cover 5, so as to avoid the button cover 5 detaching from the protection cylinder 4.

[0032] Reference Figures 1 to 2 As shown, the button cover 5 has a T-shaped structure that is wider at the top and narrower at the bottom.

[0033] Reference Figures 1 to 2 As shown, two opposite guide grooves 15 are provided on the inner wall of the casing 4. Two opposite guide bars 16 are formed on the outer wall of the lower part of the limit post 8. The guide bars 16 are slidably connected to the guide grooves 15 in a matching manner. The structure of the guide grooves 15 and the guide bars 16 positions the relative positions of the limit post 8 and the casing 4, and this avoids driving the limit post 8 to rotate when the button cover 5 is rotated.

[0034] Reference Figures 1 to 2 As shown, the baffle 10 has a circular structure, and the diameter of the baffle 10 is larger than the diameter of the through hole 12.

[0035] Reference Figures 1 to 2 As shown, an internal thread hole 20 is provided at the top of the button cover 5. The diameter of the internal thread hole 20 is larger than the diameter of the baffle 10. With this structure, personnel can install the baffle 10 inside the button cover 5 and it is convenient to disassemble the baffle 10, thus facilitating the disassembly and assembly of the button cover 5 and the limit post 8.

[0036] Reference Figures 1 to 2 As shown, a T-shaped cap 17 is threadedly connected to the internal thread hole 20. With this structure, the T-shaped cap 17 can seal the internal thread hole 20, thus preventing foreign objects from entering the inside of the button cover 5.

[0037] Reference Figures 1 to 2 As shown, a hexagonal groove 18 is provided at the top of the T-shaped cap 17. With this structure, the hexagonal groove 18 is used to facilitate the rotation of the T-shaped cap 17 by a hexagonal wrench.

[0038] Reference Figures 1 to 2 As shown, anti-slip ridges 19 are provided around the outer wall of the upper part of the button cover 5. With this structure, the anti-slip ridges 19 are used to prevent the button cover 5 from sliding as much as possible when it is rotated, ensuring stable rotation.

[0039] The implementation principle of a mechanical vibration switch according to an embodiment of the present application is as follows: When in use, personnel press the button cover 5, the button cover 5 will push the limit post 8 downward, and the limit post 8 will push the reset rod 3 to squeeze the elastic piece inside the mechanical vibration switch body 1, so that the elastic piece returns to its original position, thus resetting the mechanical vibration switch body 1. Then, the pressure on the button cover 5 is released. At this time, under the elastic force of the return spring 7, the reset rod 3 can return to its original position, facilitating the next press and reset.

[0040] During the use of the mechanical vibration switch body 1, the button cover 5 and the protective cylinder 4 form a protection device for the return spring 7, thereby preventing dust accumulation in the area of the return spring 7 in a harsh environment, which may cause the return spring 7 to be unable to be pressed down. At the same time, it can also prevent dust accumulation at the connection between the housing of the mechanical vibration switch body 1 and the reset rod 3, which may affect the smooth sliding of the reset rod 3, thereby improving the applicability of the reset button assembly 2 in a harsh environment and enhancing the use stability of the reset button assembly 2.

[0041] After the return spring 7 drives the reset rod 3 to return to its position, the user rotates the button cover 5 to thread the internal thread 14 on the button cover 5 with the external thread 13 of the protective cylinder 4, thereby locking the relative positions of the protective cylinder 4 and the button cover 5. During non-use, this can prevent accidental touch by personnel and also prevent the reset rod 3 from shaking due to vibration, thus ensuring the stability of the reset button assembly 2.

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. However, such modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
