[0025] The push rod 5 includes an upper push rod 51 and a lower push rod 52, the upper push rod 51 and the lower push rod 52 are provided with a boss 53, the end of the upper push rod 51 and the end of the lower push rod 52 are provided with reverse buckles, the lower push rod 52 is provided with a lock latch mounting hole, a mechanical lock latch 9 and a lock latch spring 10 are assembled in the lock latch mounting hole; the push rod 5 is assembled in the emergency stop shell 3, the reverse buckle of the end of the upper push rod 51 is buckled and mounted with the groove 103 of the inner cap wall 101 of the emergency stop cap, the groove 103 has a downward movement stroke of 2-5 mm; the reverse buckle of the lower push rod 52 is buckled and mounted with the arc-shaped protrusion 34 of the inner wall of the lower shell end 32 of the emergency stop shell 3; the center of the push rod 5 is hollow and has an arc-shaped surface, the light emitting element of the light emitting module assembly 8 is located in the hollow center of the push rod 5.

[0026] The center spring 4 is assembled on the upper push rod 51, the upper end of the center spring 4 abuts against the inner cap wall 101 of the emergency stop cap 1, and the lower end of the center spring 4 is limited by the boss 53.

[0027] As one of the improvement schemes, the lock latch mounting hole and the corresponding mechanical lock latch 9 and lock latch spring 10 in the lower push rod 52 are provided with multiple pairs and are uniformly distributed on the lower push rod 52.

[0028] The assembly process is briefly described as follows:

[0029] First, the mechanical lock latch 9 and the lock latch spring 10 are assembled in the hole of the push rod 5, and are assembled in the emergency stop shell 3 together with the push rod 5, the center spring 4 is sleeved on the push rod 5, then the pull type high protection belt lamp emergency stop button knob head is assembled by buckling the reverse buckle mechanism of the push rod 5, finally, the waterproof pad 6 and the thread ring 7 are assembled, thus the assembly of the entire pull type high protection belt lamp emergency stop button knob head is completed, then the knob head is assembled on the light emitting module assembly 8, the light emitting module assembly 8 is assembled and connected with the buckle mechanism on the emergency stop shell 3 through the rotation buckle mechanism, thus the assembly of the entire pull type high protection belt lamp emergency stop button switch is completed.

[0030] Working principle:

[0031] By pressing the pull and stop cap 1, the push rod 5 is driven to move downward, the center spring 4 is compressed, and under the action of the elastic force, the push rod 5 carries the mechanical latch 9 to move downward, so that the mechanical latch 9 is extruded into the hole of the push rod 5 by the boss on the stop shell 3, and after the mechanical latch 9 passes the boss structure inside the stop shell 3, the mechanical latch 9 is extruded by the boss on the stop shell 3, so that the overall mechanism cannot be reset; manually pulling the pull and stop cap 1, the mechanical latch 9 slides through the boss of the stop shell 3, and is reset under the action of the pulling force.

[0032] In the structure of the utility model, the mechanical latch 9 is a machined stainless steel part, the surface is smooth, and the front end face is a circular arc structure, so that the sliding is more smooth when being stressed, and the stainless steel material is durable;

[0033] The center of the push rod 5 is an arc surface structure, so that the lamp beads in the light emitting module assembly 8 pass through the hole, the light emitted by the lamp beads in the light emitting module assembly 8 is diffusely reflected and then passes through the semi-transparent pull and stop cap, so that the light is emitted, and the more intuitive warning effect is achieved;

[0034] In the initial state diagram, the pull and stop cap 1 is pressed downward by about 2mm, the push rod 5 does not move downward, so the contact module does not act, thereby the safety protection and the anti-miscontact function are achieved;

[0035] The waterproof ring 2 has a unique "V" type structure, the V-shaped opening is installed downward in the waterproof ring installation groove, can effectively block water from entering the switch, when water flows from the pull and stop cap 1 and the stop shell 3, the assembled waterproof ring 2 is opened, so that water enters the switch inside is hindered, and the high protection effect is achieved.

[0036] The above only describes the preferred embodiments of the utility model, and does not limit the patent range of the utility model, and any equivalent structural transformation, direct or indirect application of the utility model specification content or other related product technical field is also included in the patent protection range of the utility model.
