Abstract
The utility model relates to a button switch, which comprises a mounting rack and a switch shell body arranged under and connected with the mounting rack. A button rod and a ratched wheel are sheathed inside the mounting rack. The bottom end of the button rod is provided with an upper gear wheel matched with the ratched wheel, and a button spring is the ratched wheel. A left static contact piece and a right static contact piece are provided inside the switch shell body. The right static contact piece is also provided with an elastic piece extending to the above of the left static contact piece. The lower end of the button spring is against the elastic piece. A limiting mechanism restricting the descending stroke of the ratched wheel is provided inside the switch shell body, and thus the over descending of the ratched wheel and the folding deformation caused by the over pressing of the elastic piece can be avoided.
Description
(1) technical field
The utility model relates to a kind of push-button switch.
(2) background technology
The general structure of existing push-button switch for as the patent No. be 200720151217.8 the described structure of Chinese utility model patent: comprise installing rack and be positioned at connected switch case below the installing rack, be with the button spindle and the ratchet that cooperatively interact in the installing rack, the lower end of button spindle is provided with and cogs, it is adaptive with described ratchet to cog, and is with button spring in the ratchet; Be provided with left static contact and right static contact in the switch case, also be provided with the elasticity shell fragment that extends to left static contact top on the right static contact; The lower end of button spring is against on the elasticity shell fragment.Pressing button bar during use, ratchet is descending thereupon until the ratchet redirect, rotates after the angle engagement again that cogs with button spindle.By button spring the elasticity shell fragment is pressed down, make the elasticity shell fragment contact, realize energising with left static contact.Pressing button bar once more, redirect once more, button spring resets, and elasticity shell fragment and left static contact break away from, and recover reset condition.
The shortcoming that existing this push-button switch also exists is: the position-limit mechanism that is not used in restriction ratchet downward storke, therefore in the process of pushing, cause excessively easily and press down, cause elasticity shell fragment perk distortion, in case elasticity shell fragment perk distortion, then the head of elasticity shell fragment just is difficult to contact with left static contact, causes and can't use.
(3) summary of the invention
In order to overcome the above-mentioned deficiency of existing push-button switch, the utility model provides a kind of push-button switch that can limit the downward storke of ratchet.
The technical scheme in the invention for solving the technical problem is: a kind of push-button switch, comprise installing rack and be positioned at the connected switch case of described installing rack below, be with button spindle and ratchet in the described installing rack, the lower end of described button spindle is provided with and cogs, describedly cog adaptively, be with button spring in the described ratchet with described ratchet; This has left static contact and right static contact in the described switch case, also is provided with the elasticity shell fragment that extends to described left static contact top on the described right static contact; The lower end of described button spring is against on the described elasticity shell fragment; Also be provided with the position-limit mechanism that is used to limit described ratchet downward storke in the described switch case.
Further, described position-limit mechanism is positioned at described ratchet and comes downwards to the redirect engagement place that cogs with button spindle.
Further, described position-limit mechanism comprise the front panel inboard that is positioned at described switch case the prosodetic bit slice, be positioned at the back banking stop of the rear board inboard of described switch case, described prosodetic bit slice and back banking stop are positioned on the same horizontal plane, and described elasticity shell fragment is between described prosodetic bit slice and back banking stop.
The beneficial effects of the utility model are: owing to be provided with the position-limit mechanism that is used to limit the ratchet downward storke in the switch case, so ratchet can be excessively not descending, thereby avoiding causing excessively makes the elasticity shell fragment produce to stick up to pushing of elasticity shell fragment to sell off shape.

Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of switch case of the present utility model.
Fig. 3 is an explosive view of the present utility model.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
With reference to Fig. 1, Fig. 2, a kind of push-button switch, comprise installing rack 1 and be positioned at the connected switch case 2 of described installing rack 1 below, be with button spindle 2 and ratchet 3 in the described installing rack 1, the lower end of described button spindle 8 is provided with and cogs, describedly cog adaptively, be with button spring 4 in the described ratchet 3 with described ratchet 3;
This has left static contact 6 and right static contact 7 in the described switch case 2, also is provided with the elasticity shell fragment 5 that extends to described left static contact 6 tops on the described right static contact 7;
The lower end of described button spring 4 is against on the described elasticity shell fragment 5;
Also be provided with the position-limit mechanism that is used to limit described ratchet downward storke in the described switch case 2.In the present embodiment, described position-limit mechanism is positioned at described ratchet 3 and comes downwards to the redirect engagement place that cogs with button spindle 8, the position-limit mechanism that restriction ratchet downward storke is set at this place is the most reasonable: ratchet 3 has come downwards to the position of completion status conversion, and is descending more meaningless.Position-limit mechanism described in the present embodiment comprise the front panel inboard that is positioned at described switch case 2 prosodetic bit slice 9, be positioned at the back banking stop 10 of the rear board inboard of described switch case 2, described prosodetic bit slice 9 and back banking stop 10 are positioned on the same horizontal plane, and described elasticity shell fragment 5 is between described prosodetic bit slice 9 and back banking stop 10.
Certainly the structure of position-limit mechanism is not limited to present embodiment and describes, and can also be other versions, extends upward as the bottom surface from switch case to stop positioning bar that ratchet is descending etc.Be provided with locating piece in the switch case below the elasticity shell fragment for another example, the height of locating piece is: when the elasticity shell fragment presses down when contacting with left static contact, locating piece just withstands the elasticity shell fragment.The upper surface of switch case itself can be used as position-limit mechanism for another example: the upper surface of switch case is offered and is only allowed that button spring passes through and ratchet unpassable hole.
