Embodiment Construction
[0014] Such as figure 1 From the schematic diagram shown, it can be known that the travel switch quick action mechanism of the present invention includes a link 1, an operating head 4 and a guide sleeve.
[0015] The guide sleeve is set on the outside of the control head 4 and the connecting rod 1. The guide sleeve is composed of the guide sleeve main body 2 and the guide sleeve upper cover 3. The guide sleeve main body 2 is set on the outer end of the link rod 1. The guide sleeve upper cover is set At the outer end of the control head 4.
[0016] Depend on figure 2 and image 3 As shown in the schematic diagram, it can be seen that the control head 4 is flexibly connected with the link 1, and one end of the control head 4 has a cavity for the end of the link 1 to extend into. A return spring is provided, and the link can be quickly bounced under the action of the return spring. There is a pair of stroke rods 7 on the outer wall of the link 1 close to the control head 4, a...

The invention relates to a travel switch quick-acting mechanism. The travel switch quick-acting mechanism comprises a link rod, a control head and a guide sleeve, wherein the guide sleeve is arranged at the outer sides of the control head and the link rod in a sheathing manner, the guide sleeve is composed of a guide sleeve main body and an upper cover of the guide sleeve, the guide sleeve main body is arranged at the outer end of the link rod in the sheathing manner, and the upper cover of the guide sleeve is arranged at the outer end of the control head in the sheathing manner; the control head is movably connected with the link rod, one end of the control head is provided with a cavity into which the end tip of the link rod penetrates, a reset spring is also arranged between the link rod and the control head, the link rod can rapidly bound downwards under the action of the reset spring, a pair of travel rods is arranged on the outer wall of the link rod, close to one side of the control head, a control head sliding block is arranged on the outer wall of the link rod in the sheathing manner, two ends of the control head sliding block are provided with cavities A in which the travel rods can move, and the outer side of the guide sleeve main body is also provided with a cavity B in which the travel rods can move. The travel switch quick-acting mechanism has the advantage that after the control head is pressed with a certain length, the link rod can bound downwards rapidly.
Description
technical field [0001] The invention relates to a travel switch, in particular to a travel switch quick action mechanism. Background technique [0002] Travel switch, a kind of position switch (also known as limit switch), is a commonly used small current master electrical appliance. Use the collision of the moving parts of the production machinery to make the contact move to realize the connection or break of the control circuit to achieve a certain control purpose. Usually, this type of switch is used to limit the position or stroke of the mechanical movement, so that the moving machinery will automatically stop, reverse movement, variable speed movement or automatic reciprocating movement according to a certain position or stroke. [0003] At present, the action of the link rod of the travel switch in use in the market is: when the control head is pressed down, the link rod will gradually descend as the control head is pressed down. However, in such an action proce...
