Detailed Description
The invention will be described in further detail below with reference to the accompanying drawings of specific embodiments. The description of these embodiments is provided to assist understanding of the present invention, but is not to be construed as limiting the present invention. In addition, the technical features of the embodiments of the present invention described below may be combined with each other as long as they do not collide with each other.
Referring to fig. 1-10, a trigger switch mechanism with energy storage and release is shown.
The pulling switch actuating mechanism consists of a fixed support 1, a rotating contact piece 2, a rotating support 3, a fixed support block 4, a connecting spring 5, a connecting ejector rod 6, a movable contact 7, a binding post 8, a fixed contact 9 and the like.
The stationary support 1 has a stationary shaft 10. The fixed shaft 10 extends in the left-right direction.
The rotary contact piece 2 has a contact piece left side wall 21, a contact piece right side wall 22, and a contact piece intermediate wall 23 between the contact piece left side wall 21 and the contact piece right side wall 22. The contact piece left side wall 21, the contact piece right side wall 22 and the contact piece intermediate wall 23 are integrally formed through sheet metal. The lower ends of the left contact piece side wall 21 and the right contact piece side wall 22 are respectively rotatably connected with the left and right ends of the fixed shaft 10, so that the rotary contact piece 2 can rotate around the fixed shaft 10. A contact left clamping groove 210 and a contact right clamping groove 220 are respectively formed on the top surface of the contact left side wall 21 and the top surface of the contact right side wall 22.
The rotating bracket 3 has a bracket left side wall 31 arranged on the left side of the contact piece left side wall 21, a bracket right side wall 32 arranged on the right side of the contact piece right side wall 22, and a bracket intermediate wall 33 between the bracket left side wall 31 and the bracket right side wall 32. The left side wall 31, the right side wall 32 and the middle wall 33 are formed by sheet metal integrally. The bracket intermediate wall 33 extends from the upper end of the bracket left side wall 31 to the upper end of the bracket right side wall 32. The carrier intermediate wall 33 is arranged above the rotary contact piece 2. The lower ends of the left side wall 31 and the right side wall 32 are respectively rotatably connected with the left and right ends of the fixed shaft 10, and the rotating bracket 3 can rotate around the fixed shaft 10. It can be seen that the rotary contact piece 2 rotates on the same axis as the rotary support 3.
The fixed support block 4 has a support block left side wall 41, a support block right side wall 42, and a support block intermediate wall 43 between the support block left side wall 41 and the support block right side wall 42. The support block left side wall 41 is disposed inside the contact piece left clamping groove 210. The support block right side wall 42 is disposed inside the contact piece right clamping groove 220. Thereby, the fixed support block 4 is fixed to the rotary contact piece 2. The support block intermediate wall 43 is arranged below the bracket intermediate wall 33. Preferably, the fixed supporting block 4 further has a left supporting block limiting protrusion 44 and a right supporting block limiting protrusion 45. The support block left limit projection 44 is formed on the support block intermediate wall 43. The support block left limit protrusion 44 is disposed on the right side of the contact piece left side wall 21 and abuts against the contact piece left side wall 21. The support block right limit projection 45 is formed on the support block intermediate wall 43. The supporting block right limiting protrusion 45 is arranged on the left side of the right side wall 22 of the contact piece and abuts against the left side of the right side wall. The design of the support block left limit protrusion 44 and the support block right limit protrusion 45 can limit the displacement of the fixed support block 4 in the left-right direction, so that the fixed support block 4 is better fixed on the rotary contact piece 2.
The connecting mandril 6 is provided with a first end and a second end which are opposite. The first end of the connecting ejector rod 6 is provided with an ejector rod clamping groove. The bracket intermediate wall 33 is embedded in the ejector rod clamping groove. When the rotating bracket 3 rotates, the bracket intermediate wall 33 and the ejector rod clamping groove only rotate relatively. The second end of the connecting mandril 6 is provided with a mandril guide groove. The support block intermediate wall 43 is arranged inside the ejector pin guide groove. When the rotating bracket 3 rotates, the supporting block intermediate wall 43 and the ejector rod guide groove can generate relative displacement and relative rotation.
The connecting spring 5 is arranged around the outer side of the connecting mandril 6 and between the bracket intermediate wall 33 and the supporting block intermediate wall 43.
The terminal 8 is adjacent to the fixing support 1. The binding post 8 is provided with the stationary contact 9. The stationary contact 9 corresponds to the movable contact 7.
The rotating bracket 3 is rotated counterclockwise, and the connecting spring 5 is in an energy storage state before the connecting spring 5 is in the vertical position. After the connecting spring 5 is in the vertical position, the connecting spring 5 is in an energy release state, and the connecting spring 5 helps the rotary contact piece 2 to rotate clockwise.
The rigidity of the connecting spring 5 is adjustable, and the connecting spring is designed according to the required pulling force. The greater the stiffness, the greater the pulling force.
In other embodiments, the switch actuating mechanism may be plural.
The foregoing has outlined rather broadly the more detailed description of the invention in order that the detailed description thereof herein may be better understood, and in order that the present invention may be better understood. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
