Detailed Description
The invention will be described in further detail below with reference to specific embodiments and drawings. Here, the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Referring to fig. 1 to 6, a limit protection structure for a push switch with a lamp is shown.
The lighted push switch 1 has a switch base 10. Pressing the switch base 10 downward can implement the on or off function of the lighted push switch 1.
The limiting protection structure mainly comprises a fixed bottom plate 2, a hinge assembly 3, a hollowed-out top cover 4, a limiting assembly 5, a vertical screw 6, a self-locking nut 7, a compression spring piece 8 and the like.
The fixed base plate 2 surrounds the periphery of the switch lamp cap 10. The fixed bottom plate 2 is fixedly connected with the starting lamp cap 2. The fixed base plate 2 is formed with a receiving groove 20 disposed behind the switch lamp head 10. The receiving recess 20 has an upward opening and a forward opening. The fixed base plate 2 is formed with a base plate through hole.
The hinge assembly 3 is disposed above the fixed base plate 2. The hinge assembly 3 has a hinge seat 31 and a hinge shaft 32 on the hinge seat 31. A seat through hole corresponding to the bottom plate through hole is formed on the hinge seat 31. The seat bore and the base plate bore have a common vertical axis.
The vertical screw 6 sequentially penetrates through the bottom plate through hole and the seat through hole downwards. The self-locking nut 7 is arranged below the fixed bottom plate 2. And a compression spring sheet 8 is arranged between the self-locking nut 7 and the fixed bottom plate 2.
The hollow top cover 4 is arranged above the fixed bottom plate 2. The hollow top cover 4 has a top cover top wall 41 and a top cover connecting portion 42. The top cover coupling portion 42 is formed at a rear edge of the top cover top wall 41. The top cover connecting portion 42 surrounds the periphery of the hinge shaft 32, so that the hollow top cover 4 can be turned backwards around the hinge shaft 32.
A limiting groove 100 is formed on the rear surface of the switching base 10. The stopper groove 100 has a rearward opening. The rearward opening of the position-limiting groove 100 is opposite to the forward opening of the accommodating groove 20.
The limiting assembly 5 is accommodated in the accommodating groove 20. The limiting component 5 is provided with a limiting shifting piece 51 and a movable sleeve 52. The movable sleeve 52 is disposed above (or below) the limit paddle 51. The movable sleeve 52 surrounds the periphery of the vertical screw 6. The limit shifting piece 51 is fixedly connected with the movable sleeve 52. The limit shifting piece 51 horizontally rotates around the vertical screw 6 through the movable sleeve 52 to move into or out of the limit groove 100. When the position-limiting shifting piece 51 moves into the position-limiting groove 100, the switch lamp head 10 cannot move up or down due to the position-limiting shifting piece 51, that is, the state of the press switch with the lamp is kept unchanged.
Preferably, the limiting assembly 5 further has a return torsion spring 53. The return torsion spring 53 is arranged below (or above) the limit shifting piece 51. The reset torsion spring 53 surrounds the periphery of the vertical screw 6. The return torsion spring 53 has a fixed end and a movable end. The movable end of the reset torsion spring 53 is fixedly connected with the limit shifting piece 51. The reset torsion spring 53 provides a forward elastic force to the limit shifting piece 51, so that the limit shifting piece 51 is always moved into the limit groove 100 under the condition that no external force acts on the limit shifting piece 51.
Preferably, the top cover connecting portion 42 is formed with a first spherical surface hole and a second spherical surface hole. The bottom plate spherical hole, the first spherical hole and the second spherical hole are located on the same vertical plane. When the hollow top cover 4 is in a horizontal state, the steel ball 9 is contained in the bottom plate spherical hole and the first spherical hole together, wherein one part of the steel ball 9 is in the bottom plate spherical hole, and the other part of the steel ball is in the first spherical hole. The steel ball 9 has a certain elasticity. Opening the hollowed top cover 4, a part of the steel ball 9 remains in the bottom plate spherical hole, while another part of the steel ball is displaced from the first spherical hole into the second spherical hole.
The foregoing merely represents embodiments of the present invention, which are described in some detail and detail, and therefore should not be construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
