Description

Micro-switch

Technical Field

The utility model belongs to the technical field of the switch, especially, micro-gap switch.

Background

The microswitch is a switch which has a minute contact interval and a quick action mechanism, performs a switching action by a specified stroke and a specified force, is covered by a shell, and has a driving rod outside. The micro switch has a variety of types, generally, a basic type is no auxiliary pressing accessory, different auxiliary pressing accessories can be added according to needs, and the micro switch can be divided into various types such as a button type, a reed roller type, a lever roller type, a short movable arm type, a long movable arm type and the like according to the added different auxiliary pressing switches. Wherein, the arm-moving type micro-gap switch commonly used includes casing and depression bar, depression bar among the prior art adopts the rivet usually, pivot fixed mounting is on the casing, it can make the depression bar fix on the casing to a certain extent really, but because the arm-moving type micro-gap switch uses the back for a long time, receive the back of pushing down many times on its depression bar, depression bar itself produces to warp and leads to its elastic failure, because form fixed mounting between depression bar and the casing and lead to the difficult change of depression bar, consequently just need be with arm-moving type micro-gap switch overall change, and micro-gap switch inner structure homoenergetic normal use in fact, lead to the waste on the resource easily like this.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model provides a microswitch which is convenient to install and convenient to detach and replace.

In order to realize the purpose, the utility model discloses a technical scheme is: the utility model provides a micro-gap switch, includes casing, button and is used for touching the depression bar of pressing the button, be provided with the first seam and the second of inserting that are cross arrangement on the casing and insert the seam, the first one end terminal surface that has the button by the casing extends the setting to the casing in, the second is inserted the seam and is extended the setting to the casing by the terminal surface of casing side, the depression bar is including inserting the inserted sheet of establishing in first inserting the seam, the inserted sheet corresponds second is inserted seam department and is provided with the opening, second insert seam interpolation be equipped with the opening is pegged graft complex joint piece.

Adopt above-mentioned scheme, be crisscross first slotting and second slotting through setting up on the casing, during the installation, at first insert the inserted sheet on the depression bar in the casing along first slotting, and make the opening on the inserted sheet correspond the position at second slotting, then insert the second slotting with the joint piece in order to make the joint piece insert the opening along the second slotting, thereby make and form the cooperation of pegging graft between inserted sheet and the joint piece, the inserted sheet can't deviate from first slot this moment, thereby can make the depression bar can normal use. After long-time use, when the elasticity of the compression bar is failed, the clamping sheet is pulled out from the second insertion seam, so that the insertion sheet can be separated from the first insertion seam, the compression bar with the elasticity failed is replaced by a new compression bar during replacement, then the compression bar is continuously inserted into the first insertion seam and is continuously limited through the clamping sheet, and the replacement work of the compression bar is completed. The utility model discloses easy operation when not only product installation, it is also very convenient at needs change in-process to facilitate the installation, and product simple structure is convenient for process moreover and is implemented.

As a further setting of the utility model, first slotting and second slotting are alternately perpendicular setting.

By adopting the scheme, the first inserting seam and the second inserting seam are conveniently processed, the inserting sheet and the clamping sheet are conveniently processed correspondingly, and the production efficiency is improved.

As a further setting of the utility model, be provided with the joint groove on the joint piece, the joint groove extends to set up outside the second slot, be provided with on the casing with joint groove cooperation joint is with the anti-disengaging mechanism who prevents the joint piece and deviate from.

Adopt above-mentioned scheme, set up the joint groove on the joint piece to and set up the anti-disengaging mechanism who is used for joint groove cooperation joint on the casing and can prevent that the joint piece is unexpected to be deviate from in inserting the seam from the second, can improve the stability of product.

As a further setting of the utility model, the anti-disengaging mechanism including articulated set up on the casing be used for with the joint axle of joint groove cooperation joint.

Adopt above-mentioned scheme, the joint axle can be followed articulated department and rotated to insert the joint inslot with the joint axle, conveniently spacing the joint piece through the cooperation between joint axle and the joint groove, prevent that the joint piece from deviating from the second slot.

As a further setting of the utility model, anti-disengaging mechanism is including sliding the slider that sets up on the casing, the slider corresponds the setting and is in the one end in joint groove, be provided with on the slider be used for with the grafting axle of joint groove cooperation joint.

Adopt above-mentioned scheme, as another kind of embodiment of above-mentioned scheme, the slider slides and sets up on the casing, as long as slide the grafting axle on the slider to the joint inslot when needs carry on spacingly to the joint piece to can prevent that the joint piece from deviating from the second slot, it has simple structure, convenient operation's advantage.

As a further arrangement of the present invention, the joint sheet includes a support plate and an elastic rubber layer coated on the support plate.

By adopting the scheme, the elastic rubber layer is arranged on the clamping sheet, so that the friction force between the clamping sheet and the second insertion seam can be increased through the elasticity of the elastic rubber layer when the clamping sheet is inserted into the second insertion seam, the clamping sheet can be fixed in the second insertion seam to a certain extent, the stability of a product is improved, and the supporting plate can play a role in improving the supporting strength of the clamping sheet.

The present invention will be further described with reference to the accompanying drawings.
