A lock head is fixed on the body, and a lock clip is fixed on the button cover of the button, and the lock clip is sleeved on the lock head.

[0007] Furthermore, a light-emitting diode is installed inside the button cover of the button.

[0008] Furthermore, a telescopic sleeve is provided at the connection between the button shaft and the base of the button.

[0009] (III) Beneficial Effects

[0010] Compared with the prior art, this utility model has the following advantages:

[0011] This utility model discloses a mine emergency stop interlock button device. When a conveyor belt malfunctions and needs to be stopped, pressing the main unit's emergency stop interlock button will illuminate the indicator light on the main unit, signaling an interlock signal, and the conveyor belt will stop operating. Manually resetting the emergency stop interlock button will extinguish the indicator light and release the interlock signal.

[0012] When a conveyor belt malfunctions and needs to be stopped, press the emergency stop interlock button on the public address system. The indicator light on the button will illuminate, signaling an interlock and stopping the conveyor belt. Manually resetting the emergency stop interlock button will extinguish the indicator light and release the interlock signal. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] like Figure 1 and Figure 2 The diagram shows a mine emergency stop interlocking button device, comprising a switch base 1, a fixed base body 2 on the switch base 1, a button 3 mounted on the base body 2, and the button shaft of the button 3 passing through the base body 2 and extending out of the switch base 1. A tapered sleeve 31 is provided at the tail end of the button shaft of the button 3. A micro switch 11 is provided on the switch base 1 at the position corresponding to the tapered sleeve 31, and the button shaft of the button 3 extends out of the switch base 1 and contacts the micro switch 11. A groove 21 is provided inside the base body 2, and a steel ball 23 is connected to the groove 21 by a spring 22. The tail end of the spring 22 is connected to a set screw 24, and the set screw 24 is threaded into the groove 21. The steel ball 23 contacts and cooperates with the button shaft of the button 3. A lock head 25 is fixed on the base body 2, and a lock clip 32 is fixed on the button cover of the button 3, and the lock clip 32 is sleeved on the lock head 25.

[0018] In a preferred embodiment, a light-emitting diode 33 is disposed inside the button cover of button 3.

[0019] In a preferred embodiment, a telescopic sleeve 34 is provided at the connection between the button shaft of the button 3 and the base 2.

[0020] The present invention provides a mine emergency stop interlocking button device that improves upon the shortcomings of traditional emergency stop interlocking devices, which are characterized by complex structure, difficult manufacturing, poor stability, and inconvenient operation and maintenance.

[0021] The base 2 is a one-piece machined part, and the inner hole of the base 2 and the button shaft are freely movable with a clearance fit. Adjusting the depth of the set screw 24 inside the base 1 changes the spring force, ensuring that the force between the steel ball 23 and the groove of the button shaft is moderate and the positioning is accurate and reliable. The tapered sleeve 21 fixed at the tail of the button shaft triggers the micro switch 11 fixed on the switch base 1 of the base 2, sending an emergency stop lock signal. The button shaft slot moves the lock card 32 to expose the lock hole on the lock head 25, allowing manual locking to avoid accidental operation. The button 3 is hollow and has a built-in light-emitting diode 33 with glue protection. When the button is pressed, the diode emits light as a warning. The button cover is interference-fitted with the button shaft to prevent foreign objects from entering. One end of the telescopic sleeve 34 is installed on the slot of the base 2, and the other end is installed on the slot of the button shaft to prevent foreign objects from entering. At the same time, an oil O-ring is installed between the button shaft and the inner diameter of the base to further ensure the button's sealing. This emergency stop lock button lock device has a simple structure, reliable function, strong sealing, and strong warning effect.

[0022] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention. The technical content for which protection is sought in the present invention has been fully described in the claims.
