[0019] The embodiments of this utility model are further described below with reference to the accompanying drawings.
[0020] like Figures 1 to 6As shown, an emergency stop switch designed to prevent misoperation includes a toggle head and a contact module 13. The toggle head is mounted on the contact module 13 and includes an emergency stop cap 1, an emergency stop push rod 3, and an emergency stop housing 6. The emergency stop housing 6 has two arc-shaped baffles 15 on its upper part. The emergency stop push rod 3 includes an emergency stop cap mounting position 31 and a ball bearing mounting post 32. The ball bearing mounting post 32 has a first round hole 33, the emergency stop cap mounting position 31 has an external thread 34, and a second round hole 35 at its bottom. The emergency stop housing 6 has a crescent groove 14 inside. A ball bearing 4 is installed in the first round hole 33 through a ball spring 5. The emergency stop push rod 3 is mounted in the emergency stop housing 6 and rotates 45° to be locked in place by a locking post. The ball bearing 4 springs into the crescent groove 14 of the emergency stop housing 6 under the elastic force of the ball spring 5.
[0021] The emergency stop cap 1 has a torsion spring mounting hole at its bottom. A torsion spring is provided between the emergency stop cap 1 and the emergency stop push rod. One end of the torsion spring is installed in the torsion spring mounting hole, and the other end is installed in the second round hole on the emergency stop cap mounting position. The emergency stop cap 1 is fastened to the emergency stop push rod 3 by the internal thread and the external thread on the emergency stop cap mounting position 31.
[0022] The bottom of the emergency stop housing 6 is equipped with a slider 7 and a metal washer 8, which are locked onto the emergency stop housing 6 by self-tapping screws 9.
[0023] The lower part of the emergency stop housing 6 is provided with external threads. A waterproof gasket 10 and an anti-rotation ring 11 are installed on the external threads at the lower part of the emergency stop housing 6, and then the threaded ring 12 is fastened to the external threads.
[0024] Assembly process in brief:
[0025] Insert the ball spring 5 and ball 4 into the first round hole 33 of the emergency stop push rod 3, then insert the torsion spring 2 into the second round hole 35 at the upper end of the emergency stop push rod 3. Finally, rotate this part about 45° and insert it into the emergency stop housing 6. Install the slider 7, metal washer 8 and self-tapping screw 9 on the bottom of the emergency stop housing 6 and lock them in place. Then, fasten the emergency stop color cap 1 to the emergency stop push rod 3 with threads. Finally, install the waterproof pad 10, anti-rotation ring 11 and threaded ring 12 from the bottom of the emergency stop housing 6 in sequence. Finally, install the contact module assembly 13. The assembly of the entire illuminated push button switch is now complete.
[0026] Working principle:
[0027] When the customer needs to disconnect the circuit, pressing the emergency stop cap 1 pushes the emergency stop push rod 3 and slider 7 to trigger the contact module assembly 13 to disconnect the contacts. The ball 4, under the elastic force of the ball spring 5, bounces into the crescent groove of the emergency stop housing 6, forming a self-locking state, thereby stopping the circuit from running. When the equipment needs to be restored, rotating the emergency stop cap 1 clockwise causes the ball 4 to slide out of the crescent groove structure. Under the elastic force of the torsion spring 2, the entire button mechanism resets, the pressure on the contacts disappears, and the contacts reset, restoring the circuit to normal operation.
[0028] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made using the content of the present utility model specification, or direct or indirect applications in the technical fields of other related products, are similarly included within the patent protection scope of the present utility model.
