The micro-motion driving structure of the existing micro-motion switch is complex, the minimum size of the micro-motion switch is limited, and the reliability and the service life of the micro-motion switch are influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the not enough of prior art, provide a utilize the lever to trigger and the micro-gap switch structure that resets, its compact structure, easily realization, product are small.
One technical scheme for achieving the above purpose is as follows: a microswitch structure triggered and reset by utilizing a lever comprises a microswitch seat, a trigger button arranged on the microswitch seat and a trigger structure controlled by the trigger button, and is characterized by also comprising an inclined rod, a trigger rod, a limiting leading-out rod and a tension spring;
the inclined rod is arranged in the microswitch seat and is of an L-shaped structure, the end part of the short edge of the inclined rod is abutted against the bottom of the trigger button, and the inclined rod can rotate around the end part of the long edge of the inclined rod when the trigger button is pressed;
the short edge of the diagonal rod is sleeved with the trigger rod, the end part of the trigger rod is provided with a contact, when the trigger button bounces, the contact touches the first position of the trigger structure, and when the trigger button is pressed, the diagonal rod drives the trigger rod to rotate, so that the contact touches the second position of the trigger structure;
the trigger rod is hung with the tension spring, when the contact touches the first position of the trigger structure, the tension spring contracts, and when the contact touches the second position of the trigger structure, the tension spring stretches;
the limiting leading-out rod is fixed in the microswitch seat and led out outwards, the hanging section and the extension section are extended, the tension spring is hung on the hanging section, and the end part of the long edge of the inclined rod is abutted against the turning point of the hanging section and the extension section.
Furthermore, the trigger button is arranged in a microswitch groove formed in the side wall of the microswitch seat, and the microswitch groove extends towards the inside of the microswitch seat to limit the displacement of the short rod of the inclined rod.
The utility model discloses an utilize micro-gap switch structure that lever triggered and reset, the mechanical structure who has adopted the down tube to drive the trigger bar carries out micro-gap switch's trigger control to carry out reset control through the extension spring, mechanical structure is simple and easy and firm, has reduced whole switch's volume greatly, has improved the practicality and the application scope of product.
Drawings
Fig. 1 is a schematic structural view of a microswitch structure triggered and reset by a lever according to the present invention when a trigger button is bounced;
fig. 2 is a schematic structural view of the microswitch structure triggered and reset by the lever according to the present invention when the trigger button is pressed.
Detailed Description
In order to better understand the technical solution of the present invention, the following detailed description is made by specific embodiments:
referring to fig. 1, the utility model discloses a micro-gap switch structure that utilizes lever to trigger and reset, including micro-gap switch seat, set up trigger button 2 on micro-gap switch seat, accept trigger button 2 to carry out trigger structure 1, down tube 6, trigger bar 5, spacing pole 3 and the extension spring 4 of drawing forth.
The side surface of the micro switch seat is provided with a trigger button groove, and the trigger button 2 is movably inserted in the trigger button groove. The trigger button groove extends towards the inner side of the micro switch seat to form a limit structure. The down tube 6 is arranged in the micro switch seat and is of an L-shaped structure, the end part of the short edge of the down tube is abutted against the bottom of the trigger button 2, and the displacement of the short edge is limited by the limiting structure. The short edge of the diagonal rod 6 is sleeved with a trigger rod 5, and the end part of the trigger rod 5 is provided with a contact. The trigger structure 1 is arranged on the side surface of the microswitch seat and led out outwards, and is divided into a first contact and a second contact. The trigger lever 5 is driven by the diagonal lever 6 to swing, so that the contact contacts with the first contact or the second contact respectively. The limit leading-out rod 3 is fixed in the microswitch seat and led out outwards, and comprises a hanging section 31 and an extension section 32. The tension spring 4 is hung between the hanging section 31 and the trigger rod 5. The end of the long side of the diagonal member 6 abuts on the inflection point formed by the hitching section 31 and the extending section 32, thereby restricting the movement of the diagonal member 6.
Referring to fig. 1 and 2, when the trigger button 2 is popped up, the inclined rod 6 drives the trigger rod 5, so that the contact of the trigger rod 5 is naturally contacted with the first contact of the trigger structure 1. When the trigger button 2 is pressed, the inclined rod 6 rotates around the end part of the long edge of the inclined rod to drive the trigger rod 5 to tilt and swing, so that the contact of the inclined rod is contacted with the second contact of the trigger structure 1 to form switch signal transmission. The tension spring 4 is in a stretched state at this time. When the trigger button 2 is not pressed, the tension spring 6 contracts, so that the microswitch is driven to reset.
It will be appreciated by those skilled in the art that the above embodiments are only for illustrating the present invention and are not to be used as limitations of the present invention, and that changes and modifications to the above described embodiments will fall within the scope of the claims of the present invention as long as they are within the spirit and scope of the present invention.
