[0032] Example:

[0033] See also Figure 1-4 A safety emergency stop box for large tire equipment includes a safety emergency stop box 1 and a key 7. An emergency stop device 2 is installed inside the safety emergency stop box 1. The front end of the safety emergency stop box 1 is connected to a sealing door panel 3 by a hinge. A storage slot 4 is provided at the top side end of the safety emergency stop box 1. A locking member 5 is installed inside the storage slot 4. A limiting hole 6 corresponding to the storage slot 4 is provided at the outer end of the sealing door panel 3.

[0034] During use of this solution, in order to avoid the phenomenon that other personnel turn on the power again after the existing personnel cut off the power of the entire equipment during maintenance or repair of large tire equipment, in this embodiment, the personnel can press the emergency stop device 2 every time they maintain or repair the equipment, so that all parts of the equipment cannot be operated. After the maintenance personnel have completed the maintenance, they can turn on the emergency stop to power on the equipment. Then the personnel rotates the sealing door panel 3 to make it fit with the side of the safety emergency stop box 1, and then inserts the key 7 into the interior of the locking member 5 and rotates it, thereby driving the locking member 5 to enter the interior of the limiting hole 6, so that the safety emergency stop box 1 and the sealing door panel 3 are limited. Finally, the personnel takes out the key 7 and takes it away, so that other personnel cannot open the sealing door panel 3 to perform corresponding operations on the emergency stop device 2 without the key 7, thereby protecting the safety of the maintenance personnel at work and avoiding other personnel's misoperation.

[0035] See also Figure 1-2 The receiving groove 1 4 is convex columnar and the inner wall of the outer side is provided with a thread.

[0036] More specifically, the locking member 5 includes a limiting column 51 threadedly connected between the inner walls of the receiving groove 14, the rear end of the limiting column 51 is fixedly connected to the limiting ring 52, and the front end of the limiting column 51 is provided with an irregularly shaped limiting groove 1 53.

[0037] During use, the limiting post 51 is located inside the receiving groove 4, and under the corresponding thread, when the key 7 is inserted into the limiting groove 53 and rotated, it can move outward. When the limiting ring 52 contacts the extreme end of the receiving groove 4, the limiting post 51 is located between the inner walls of the limiting hole 6.

[0038] See also Figure 1-2 and Figure 4 The left and right sides of the limit column 51 are both provided with a second receiving groove 54, and the inner walls of the second receiving groove 54 are slidably connected with a magnetic column 55, and the magnetic poles of the magnetic columns 55 on the left and right sides are both set as positive poles.

[0039] More specifically, two limiting grooves 61 are provided on the left and right side walls of the limiting hole 6 .

[0040] More specifically, the key 7 includes a connecting rod 71, a front end of which is fixedly connected to a corresponding locking block 72, a rear end of which is fixedly connected to a handle 73, and an outer end of the handle 73 is provided with a through hole 74;

[0041] Negatively-set magnetic blocks 75 are embedded and installed on both the left and right sides of the locking block 72 , and a magnetic insulating plate 76 is embedded and installed on the central end of the locking block 72 .

[0042] When the lock 51 is in the closed position, the locking block 72 is pressed against the locking lever 74 and the locking lever 76 is pressed against the locking lever 74. When the lock 51 is in the closed position, the locking block 72 is pressed against the locking lever 74 and the locking lever 76 is pressed against the locking lever 74. When the lock 51 is in the closed position, the locking block 72 is pressed against the locking lever 74 and the locking lever 76 is pressed against the locking lever 74.

[0043] In this embodiment, due to the special irregular shape of the key, it is difficult for other people to open the safety emergency stop box 1 except for those who have the key, thereby preventing other people from accidentally touching the emergency stop device 2 during maintenance, causing the dangerous phenomenon of equipment startup, and greatly ensuring the safety of maintenance personnel;

[0044] Among them, in this embodiment, the setting of the magnetic insulating plate 76 can block the repulsion of the magnetic blocks 75 on both sides, avoid magnetic conflict during use, and ensure stability during use; and with the setting of the through hole 74, the person can hang the key as a whole on the side of the person by the action of the pull rope, which is not easy to be lost.

[0045] See also Figure 3 The outer end of one side of the locking member 5 is engraved with a mark 8, and the top center end of the sealing door panel 3 is engraved with a mark 2 9.

[0046] During use of this solution, by setting corresponding markers 1 8 and 2 9, the personnel can rotate the marker 1 8 on the upper side of the locking piece 5 to the corresponding marker 2 9 at the top center end of the sealing door panel 3. At this time, the magnetic columns 55 on both sides of the limiting column 51 can be engaged into the limiting groove 2 61 to complete the limiting, thereby ensuring the tightness of the safety emergency stop box 1 and the sealing door panel 3 after closing.
