Description

Technical Field

[0001] The utility model belongs to the technical field of switches, and in particular relates to a switch bidirectional pressing mechanism. Background Art

[0002] The pressing mechanism of the micro switch is mainly composed of a roller and a spring. When the movement direction of the mechanism contact piece of the micro switch is perpendicular to the movement direction of the switch button head, the roller and the spring are usually riveted together. When the mechanism contact piece pushes the roller, the roller moves toward the switch button head and presses the switch button head to turn on the switch; the spring is responsible for using its own elastic force to drive the roller to reset after the mechanism contact piece leaves, and the roller leaves the switch button head to turn off the switch. Since the spring of the pressing mechanism of the micro switch has a small stiffness, the pressing mechanism of the micro switch using a roller and a spring can only be used when the mechanism contact piece triggers the switch in a single movement direction perpendicular to the switch button head; affected by the characteristics of the spring, when the mechanism contact piece moves in two directions perpendicular to the switch button head, the force of the mechanism contact piece pressing the switch mechanism spring is unstable, resulting in the mechanical contact piece and the switch pressing mechanism spring being stuck, affecting the normal connection of the micro switch. Summary of the invention

[0003] The purpose of the utility model is to overcome the above-mentioned shortcomings and provide a rigid micro switch bidirectional trigger pressing mechanism, which can ensure that when the mechanism trigger moves bidirectionally along the vertical switch button head, the mechanism trigger presses the switch mechanism with stable force, the mechanical trigger and the switch pressing mechanism will not get stuck, and the normal connection of the micro switch will not be affected.

[0004] The purpose of the utility model and the solution of its main technical problems are achieved by adopting the following technical solutions:

[0005] The utility model discloses a bidirectional trigger pressing mechanism of a rigid micro switch, comprising a roller, a mechanism trigger, a mounting plate, a limit pin, a fixing pin and a roller bracket, and is characterized in that: the limit pin and the fixing pin are respectively mounted on the mounting plate, the middle part of the roller bracket is sleeved on the outside of the fixing pin and a nut is screwed on it, one end of the roller bracket contacts the limit pin, and the other end of the roller is mounted, and the upper and lower ends of the roller contact the switch button head and the mechanism trigger respectively.

[0006] The roller can rotate on the bracket.

[0007] The bracket is rotatable around the fixing pin.

[0008] The mechanism triggering member can move left and right at the lower end of the roller.

[0009] The switch button head is installed at the lower end of the switch, and the switch button head can be extended and retracted at the lower end of the switch.

[0010] Compared with the prior art, the utility model has obvious beneficial effects; it can be seen from the above technical scheme that: by installing the limit pin and the fixing pin on the mounting plate respectively, the middle part of the roller bracket is sleeved on the outside of the fixing pin and the nut is screwed on, one end is in contact with the limit pin, and the other end is installed with a roller, and the upper and lower ends of the roller are in contact with the switch button head and the mechanism trigger respectively. The switch is fixed to the mounting plate by screws, and only the button head can move when pressed by the roller; the roller bracket is fixed to the mounting plate by screws, and can rotate around the fixing pin when pushed by the mechanism trigger; the fixing pin is fixed to the mounting plate by screws to provide support for the roller bracket; the limit pin is fixed to the mounting plate by screws, which can limit the position of the roller bracket and provide the roller bracket with an initial correct position; the roller is fixed to the roller bracket by rivets, and the roller can rotate around the rivets, and when the roller is stressed, it can drive the roller bracket to rotate around the fixing pin; the mounting plate is installed at a relatively suitable position relative to the mechanism trigger by screws to ensure that the mechanism trigger can correctly push the roller. The limit pin on the mounting plate can limit the position of the roller bracket to ensure that the roller bracket is in the correct position when the switch is disconnected. When the mechanism trigger moves in both directions along the vertical switch button head, the mechanism trigger presses the switch mechanism with stable force, and the mechanical trigger and the switch pressing mechanism will not get stuck, which will not affect the normal connection of the micro switch.

[0016] The specific implementation methods, structures, features and functions of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0017] The utility model discloses a bidirectional trigger pressing mechanism of a rigid micro switch, comprising a switch button head 2, a switch 1, a roller 3, a mechanism trigger 4, a mounting plate 5, a limit pin 6, a fixing pin 7, and a roller bracket 8, characterized in that: the limit pin 6 and the fixing pin 7 are respectively mounted on the mounting plate 5, the middle part of the roller bracket 8 is sleeved on the outside of the fixing pin 7 and a nut is screwed on it, one end of the roller bracket 8 contacts the limit pin 6, and the other end is inserted into the roller 3 and riveted with a rivet, the upper and lower ends of the roller 3 contact the switch button head 2 and the mechanism trigger 4 respectively, the roller 3 can rotate on the bracket 8, the bracket 8 can rotate around the fixing pin 7, the mechanism trigger 4 can move left and right at the lower end of the roller 3, the switch button head 2 is mounted at the lower end of the switch 1, and the switch button head 2 can be extended and retracted at the lower end of the switch 1.

[0018] When using, see Figure 3-4 , install the mechanism trigger 4 on the slide rail 9, and ensure that the roller 3 is in contact with the switch button head 2 by adjusting the position of the limit pin 6 and the roller bracket 8; adjust the position of the mounting plate 5 to ensure a suitable spacing between the mechanism trigger 4 and the roller 3. Figure 2 When the switch 1 is turned on in the +X axis direction, the mechanism trigger 4 pushes the roller 3 to move upward, and the roller 3 rolls and rotates around the rivet. At the same time, the roller 3 drives the middle part of the roller bracket 8 to rotate around the fixed pin 7. The roller 3 presses the switch button head 2, and the switch button head 2 is connected to the switch 1. When the mechanism trigger 4 completely passes through the roller 3, it is separated from the roller 3. The roller 3 moves downward under the action of gravity, driving the middle part of the roller bracket 8 to rotate around the fixed pin 7, and the switch button head 2 is separated from the roller 3, and the switch 1 is disconnected; when the mechanism trigger 4 is moved along Figure 2 -When the switch 1 is turned on in the X-axis direction, the mechanism trigger 4 pushes the roller 3, and the roller 3 rolls and rotates around the rivet, and at the same time rotates around the fixing pin 7 with the middle of the roller bracket 8. The roller 3 moves upward to press the switch button head 2, and the switch 1 is turned on. When the mechanism trigger 4 completely passes through the roller 3 and disengages, the switch 1 is turned off.

[0019] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
