A mine anti-miscontact alarm switch

Abstract

This utility model proposes a mine-use anti-accidental-touch alarm switch, including a housing, a button, a first pressing plate, a second pressing plate, a base plate, a first spring, a second spring, a first telescopic sleeve, a second telescopic sleeve, a first conductive element, and a second conductive element. A second pressing element is located below the first pressing element. When the first pressing element is pressed, the first telescopic sleeve is compressed to its shortest length, but not enough to move the second pressing element or to bring the first pressing element into contact with the second pressing element. Therefore, the alarm switch will not be energized, and the alarm will not be activated. The first spring can quickly return the button to its original position. This prevents workers from accidentally pressing the alarm switch button, causing a false alarm. When an alarm is needed, the button must be pressed firmly to its lowest position, causing the second pressing element to move towards the second conductive element. The second telescopic sleeve shortens, bringing the first conductive element into contact with the second conductive element and energizing it, thus activating the alarm.

[0001] This utility model relates to the technical field of mining-related equipment, and in particular to a mining alarm switch to prevent accidental activation. Background Technology

[0002] Coal mining typically involves drilling deep underground to access the mining area for coal collection and transportation. However, underground coal mining areas are usually located in enclosed spaces, making the work inherently dangerous and prone to accidents such as equipment damage or collapses. In case of an accident or danger, it is crucial to press the alarm button immediately to alert everyone to take appropriate action. However, due to the confined space and frequent movement of workers underground, the alarm switch may be accidentally activated, causing a false alarm. Utility Model Content

[0022] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0023] The following describes an embodiment of the mine-use anti-accidental-touch alarm switch with reference to the accompanying drawings.

[0024] like Figure 1 , 3 As shown in the figure, this utility model embodiment proposes a mine-use anti-accidental-touch alarm switch, including: a housing 1, a button 2, a first pressing element, a second pressing element and a conductive element, the housing 1 is a hollow cylindrical structure; the button 2 is located above the housing 1.

[0025] The first pressing element is located inside the outer casing 1. The first pressing element includes a first pressing plate 4, a first spring 6, a second pressing plate 7, and a first telescopic sleeve 5. The first pressing plate 4 is located above the second pressing plate 7. The first pressing plate 4 is connected to the bottom of the button 2. The first pressing plate 4 and the second pressing plate 7 are arranged in parallel. The first telescopic sleeve 5 is connected between the first pressing plate 4 and the second pressing plate 7. The first spring 6 is sleeved on the outer periphery of the first telescopic sleeve 5.

[0026] The second pressing member is located inside the outer casing 1 and below the first pressing member. The second pressing member includes a second spring 9, a base plate 12 and a second telescopic sleeve 10. The base plate 12 is located below the second extrusion plate 7 and is fixedly connected to the bottom of the outer casing 1. The base plate 12 is arranged parallel to the second extrusion plate 7. The second telescopic sleeve 10 is connected between the second extrusion plate 7 and the base plate 12. The second spring 9 is sleeved on the outer periphery of the second telescopic sleeve 10. The first pressing member, the second pressing member and the outer casing 1 are all coated with an insulating layer.

[0027] The conductive element is located inside the outer casing 1. The conductive element is connected to the alarm via a wire. The conductive element includes a first conductive element 8 and a second conductive element 11. The first conductive element 8 is connected to the lower part of the second pressing plate 7, and the second conductive element 11 is connected to the upper part of the base plate 12. The first conductive element 8 and the second conductive element 11 are arranged correspondingly in the vertical direction, and there is a gap between the first conductive element 8 and the second conductive element 11. When the second pressing element moves downward, it drives the first conductive element 8 to move toward the second conductive element 11 and come into contact with the second conductive element 11 to conduct electricity.

[0028] This embodiment of the invention, by setting a first pressing member and a second pressing member, ensures that when the first pressing member is pressed, the first telescopic sleeve 5 is compressed to its shortest length, but not enough to move the second pressing member or to make contact between the first and second pressing members. Therefore, the alarm switch will not be energized, and the alarm will not be activated. Due to the restoring force of the first spring 6, the button 2 can be quickly returned to its original position. This prevents personnel from accidentally pressing the alarm switch button 2, which could lead to a false alarm.

[0029] When an alarm is needed, the button 2 should be pressed down to the bottom, causing the second pressing element to move toward the second conductive element 11. The second telescopic sleeve 10 will shorten, thereby energizing the first conductive element 8 and the second conductive element 11, and activating the alarm.

[0030] When the alarm is not needed, the alarm switch will not be powered on, saving energy.

[0031] In some embodiments, such as Figure 2 , 3 As shown, the second pressing component also includes a third pressing plate 14 and a buffer block 13. The third pressing plate 14 and the buffer block 13 are located below the second pressing plate 7 and are arranged parallel to the second pressing plate 7. The buffer block 13 is connected between the second pressing plate 7 and the third pressing plate 14. The second telescopic sleeve 10 is connected between the third pressing plate 14 and the base plate 12. The first conductive component 8 is connected below the third pressing plate 14. By setting the buffer block 13, an additional layer of protection against accidental touches can be added, further preventing personnel from accidentally touching the alarm switch button 2 and causing the alarm to sound false.

[0032] Furthermore, a press-locking element can be provided between the third pressing plate 14 and the base plate 12, which allows the first conductive element 8 and the second conductive element 11 to maintain contact and energize for a long time, keeping the alarm switch in a continuously open state without requiring constant pressing by personnel. The press-locking element is a conventional structure and will not be described in detail here; the principle of a press-type ballpoint pen can be referenced.

[0033] In some embodiments, such as Figure 2 As shown, the upper end of the first spring 6 is fixedly connected to the lower end of the first extrusion plate 4, the lower end of the first spring 6 is fixedly connected to the upper end of the second extrusion plate 7, the upper end of the second spring 9 is fixedly connected to the lower end of the third extrusion plate 14, and the lower end of the second spring 9 is fixedly connected to the upper end of the base plate 12.

[0034] In some embodiments, such as Figure 2 As shown, the first extrusion plate 4, the second extrusion plate 7, and the third extrusion plate 14 are all disc structures and slide in contact with the inner wall of the outer shell 1.

[0035] In some embodiments, such as Figure 1 , 2As shown, the first conductive element 8 is a conductive rod arranged vertically, and the upper end face of the second conductive element 11 has a slot. The conductive rod is inserted into the slot. Both the first conductive element 8 and the second conductive element 11 are made of metal. By designing the first conductive element 8 and the second conductive element 11 as a plug-in structure, the contact conductive area can be increased, ensuring the response of the alarm.

[0036] In some embodiments, such as Figure 1 , 2 As shown, the first extrusion plate 4 is fixedly connected to the bottom of the button 2 by the connecting post 3, and the outer diameter of the connecting post 3 is smaller than the outer diameter of the first extrusion plate 4.

[0037] In some embodiments, such as Figure 1 , 2 As shown, the first conductive element 8 is located near the edge of the third extrusion plate 14, and there is a space between the first conductive element 8 and the second conductive element 11 and the second spring 9. This is to prevent the second spring 9 from wearing down due to prolonged friction with the first conductive element 8.

[0038] In some embodiments, the buffer block 13 is made of foam.

[0039] The present invention will be further illustrated by specific embodiments below.
