Description
Technical field
The utility model relates to a kind of button, the button that particularly uses on elevator.
Background technology
Referring to accompanying drawing 1,2, in the prior art, the button of control elevator is by keycap 1, overcoat 3 and wiring board combination 6 are formed, be fixed in sleeve spring 2 on the column in the keycap at the openend of keycap, one end of overcoat 3 is buckled on the keycap openend that spring is housed, the other end at overcoat is fixed together with keycap and the overcoat that locking plate 4 and screw 5 will be equipped with spring, wiring board combination 6 with the connection of overcoat 3 by 2 castings φ 2.2 on the coat rivet hot post 18 and wiring board on the hole 7 of two reservations realize: wiring board is made up two preformed holes 7 of 6 and is enclosed within on two rivet hot posts 18 of overcoat.Because the preformed hole in the wiring board combination is the external diameter that is a bit larger tham the rivet hot post, the wiring board combination is fixing not living with overcoat like this.In this state, use the rivet hot machine to push down on the rivet hot post of two overcoats that have been enclosed within preformed hole on the wiring board, the rivet hot post is heated and produces distortion, has formed 2 circular end surface greater than two preformed holes on the wiring board on the top of rivet hot post.The wiring board combination is fixed together by the circular end surface on the strained rivet hot post with overcoat.Because very thin of the circular end surface that temperature distortion forms on this rivet hot post, mechanical strength is lower, and after long-term the use, the circular end surface of two temperature distortions on the rivet hot post is easy to come off, and damages.Cause wiring board to come off, and then produce the elevator operation troubles.
The utility model content
The purpose of this utility model is to remedy the deficiencies in the prior art, provides a kind of wiring board to connect more reliable elevator button.
Elevator button, has keycap, sleeve spring on the end with column of keycap, one end of overcoat is buckled in the openend of the keycap that spring is housed, the other end at overcoat is fixed together with keycap and the overcoat that locking plate and screw will be equipped with flexible member, it is characterized in that: also be provided with the corresponding screw hole in position on the coat with in the wiring board combination, overcoat and wiring board fixed by screw.
Above-mentioned elevator button also is provided with buckle on the outer face of overcoat, this snap fit is passed through in the hole corresponding to snapped-in position in the wiring board combination.
Wiring board combination comprises a wiring board, and welding or be pasted with electronic devices and components on the wiring board comprises luminous tube, diode, and socket.All set of devices on the wiring board install, and just can be called the wiring board combination.
Compared with prior art, the beneficial effects of the utility model are: use two screws that the wiring board combination is fixed together with overcoat, can use for a long time very securely.The buckle that puts outward also can block the wiring board combination with overcoat; wiring board can not come off, but wiring board combination this moment to lean on the connection of screw to eliminate with the apertured existence of meeting between the overcoat; so screw is most important mode, buckle is the protection to screw fixation method.This mode has fundamentally solved the defective that prior art exists; The long-term wiring board obscission of using can not occur again.
