DETAILED DESCRIPTION

[0026] The embodiments of the utility model are further explained below in combination with the drawings.

[0027] As Figures 1 to 12 shown: integrated rotary drawing with lamp emergency stop button, emergency stop head 20 is connected with the first reset sleeve buckle 21 of torsion reset sleeve 20 through emergency stop head buckle 11, the second reset sleeve buckle 22 of torsion reset sleeve 20 is movably connected with lock bolt 30 through first lock bolt buckle 31, lock bolt 30 is limited through second lock bolt buckle 33 and shell clamping groove 51 with shell 50, lock bolt assembly 30-70-80 is installed in shell 50, torsion spring 60 is arranged between torsion reset sleeve 20 and lock bolt 30, the lower end of emergency stop knob's shell 50 is provided with contact seat assembly.

[0028] Lock bolt assembly 30-70-80 is composed by installing lock pin 70 and lock pin spring 80 in lock bolt hole 32, and lock bolt hole 32 is symmetrically arranged on both sides of lock bolt 30. Shell 50 is provided with spiral shell boss 23, and lock bolt 30 is movably arranged between shell boss initial position 52 and shell boss locking position 53. Waterproof ring installation groove is arranged in the inside of shell 50, and waterproof ring 40 is located in waterproof ring installation groove and forms sealed connection with lock bolt 30.

[0029] The contact seat assembly is assembled in the contact seat 140 by the push rod 90, the contact 100, the movable contact bridge 110, the contact spring 120, and the static contact plate 170. The movable contact bridge 110 is installed on the push rod 90 through the push rod buckle 91, and the contact spring 120 in the contact seat 140 pushes the movable contact bridge 110 and the contact 100 to close through the elastic force.

[0030] The lamp holder 130 is connected to the contact seat assembly through the contact ring 150, and the lamp insert 160 and the lamp shell are installed in the lamp holder.

[0031] The lock bolt 30 has a space, and the lamp holder 130 is located in the space. The emergency stop head 10 is provided with a visible window. The visible window is used for visualizing the on-off state of the emergency stop button. The light in the internal lamp holder of the emergency stop button emits light, and the light can be seen through the visible window.

[0032] The safety travel action of the emergency stop button is implemented as follows: the lock bolt assembly 30-70-80 is installed in the shell 50. The lock pin 70 is fixed in the initial position 52 of the shell boss under the pressure provided by the lock pin spring 80. The emergency stop head 10 is pressed, and the torsion reset sleeve 20 is compressed under the action of the force, and the torsion spring 60 stores the force value. In this section of the stroke, the lock bolt assembly 30-70-80 is kept in the initial position without change under the force provided by the contact spring 80.

[0033] The ejection action of the emergency stop button is implemented as follows: when the emergency stop head 10 is continuously pressed, the torsion reset sleeve 20 continuously presses the torsion spring 60 and stores the pressure. When the force value stored by the torsion spring 60 is greater than the force value of the lock pin spring 80, the lock bolt assembly 30-70-80 is instantly ejected and reaches the locking position 53 of the shell boss, and the contact is disconnected.

[0034] The pull reset action of the emergency stop button is implemented as follows: the emergency stop head 10 is pulled, and the lock bolt assembly 30-70-80 moves upward under the driving of the buckle mechanism of the emergency stop head 10 and the torsion reset sleeve 20 and the torsion reset sleeve 20 and the lock bolt 30. The lock pin 70 is pulled out of the locking position 53 of the shell boss, continues to move upward, reaches the initial position 52 of the shell boss, and completes the pull reset.

[0035] The rotation reset action of the emergency stop button is implemented as follows: the emergency stop head 10 is rotated clockwise, and the emergency stop head boss 12 moves upward along the shell boss 23 under the driving of the clockwise force. Because the lock bolt 30 and the shell 50 are limited in rotation by the lock bolt buckle 33 and the shell buckle slot 51, only upward movement is allowed. With the upward movement of the lock bolt assembly 30-70-80, the lock pin 70 is pulled out of the locking position 53 of the shell boss, continues to move upward, reaches the initial position 52 of the shell boss, and completes the rotation reset.

[0036] The above merely describes preferred embodiments of the present application, and is not intended to limit the patent scope of the present application, and any equivalent structural transformation or direct or indirect application of the technical field of other related products using the content of the present application specification is also included in the patent protection scope of the present application.
