Abstract

The utility model discloses a locking structure from lock -switch, its technical scheme main points are locking structure from lock -switch, the button that slides and be connected including the casing, with the casing, be equipped with the elastic component that supplies the button to reset between casing and button, be equipped with the hook spring on the casing, the button is equipped with the recess for catching hold of the spring position with a hook, be equipped with the peach core that supplies hook spring lock in the recess, the peach core closes the face including the spigot surface that supplies the laminating of hook spring to slide, the hook that supplies hook spring hook to close, and the spigot surface slant sets up, hook spring bottom is including the bending segment of anticlockwise buckling. In the use, press the button and from reset state to the auto -lock state, catch hold of the spring with a hook and progressively slide along the spigot surface to the bending segment is anticlockwise buckled and is had the elastic potential energy that drives top rotate clockwise, and the elastic potential enabled its automatic hook that turns over and closes the face when operation button left the hook and closes, had avoided the card phenomenon at the peach core, had promoted smooth degree.

Description

A kind of latch-up structure of self-lock switch

Technical field

The utility model relates to a kind of switch, and more particularly, it relates to a kind of latch-up structure of self-lock switch.

Background technology

Self-lock switch is a kind of common push-button switch.At shift knob on time for the first time, switch connection also keeps, i.e. self-locking, and in shift knob second time on time, switch disconnects, and Simultaneous Switching button ejects.

At present, self-lock switch disclosed on market, often self-locking structure is complicated, easily affects by individual part, and self-locking structure is unstable, is not easy to automatically lock, and easily produces card.

Utility model content

For the deficiency that prior art exists, the purpose of this utility model is to provide that a kind of structure is simple, the latch-up structure of the self-lock switch of stability and high efficiency, operation smoothness.

For achieving the above object, the utility model provides following technical scheme: a kind of latch-up structure of self-lock switch, the button comprise housing, being connected with housing slippage, the elastic component resetted for button is provided with between described housing and button, described housing is provided with spring hook, described button is provided with groove relative to spring hook position, is provided with the peach core fastened for spring hook in described groove; Described peach core comprises the spigot surface for spring hook laminating slippage, and what hook together for spring hook hooks together face, the oblique setting of spigot surface; The bending segment of bending is counterclockwise comprised bottom described spring hook.

The utility model is set to further: be provided with spacing block set in described groove.

The utility model is set to further: be provided with above spigot surface in described groove and prevent back projection.

The utility model is set to further: described housing is provided with inspection hole relative to spring hook position.

Compared with prior art, the utility model has the advantage of: in use, push button from reset mode to self-locking state, spring hook is along spigot surface progressively slippage, and bending segment bends the elastic potential energy having and drive top to rotate clockwise counterclockwise, operation push-button leaves elastic potential energy when hooking together face makes it automatically turn over the face of hooking together, and avoids the Caton phenomenon at peach core, improves fluency.

Embodiment

Referring to figs. 1 through Fig. 5, the utility model embodiment is described further.

A kind of latch-up structure of self-lock switch, comprise housing 1, the button 2 be connected with housing 1 slippage, the elastic component resetted for button 2 is provided with between housing 1 and button 2, elastic component can be preferably spring 3, housing 1 is provided with spring hook 4, button 2 is provided with groove 5 relative to spring hook 4 position, it is movable therein that spring hook 4 buckles into groove 5, the peach core 6 fastened for spring hook 4 is provided with in groove 5, peach core 6 comprises to fit the spigot surface 61 of slippage for spring hook 4, pushing button 2 from the process resetting to self-locking, spring hook 4 is advanced along spigot surface 61 slippage, the oblique setting of spigot surface 61 provides a concrete glide direction, so direct of travel of spring hook 4 i.e. oblique, peach core 6 also comprises the face that hooks together 62 hooked together for spring hook 4, when self-locking state, spring hook 4 namely with hook together that face 62 hooks together.

As shown in Figure 4, comprise the bending segment 41 of counterclockwise bending bottom spring hook 4, conflicting with housing 1 inwall of bending segment 41, has certain elastic potential energy, and the top of bending segment 41 that the opposition of this elastic potential energy makes keeps the trend that rotates clockwise; This is pushing button in 2 processes from reset mode to self-locking state, avoid bending segment 41 to be stuck in peach core 6 and can not to swing, when leaving the face 62 of hooking together, elastic potential energy makes its automatic retracted, achieves higher fluency and stability, avoid Caton phenomenon during self-locking, improve use feel.

Preferably, be provided with spacing block set 51 in groove 5, when reset mode, spring hook 4 and groove 5 inwall are fitted, and its spacing block set 51 prevents spring hook 4 from surprisingly skidding off, and ensure that stability and the useful life of its structure.

Preferably, be provided with above spigot surface 61 in groove 5 and prevent back projection 52, prevent back that projection 52 and buckle projection define the course of a spring hook 4, in this course, prevent back that projection 52 serves the effect preventing spring hook 4 toward rollback, improve useful life.

Preferably, housing 1 is provided with inspection hole 11 relative to spring hook 4 position, the situation of inner spring hook 4 can be observed by inspection hole 11 in time, when spring hook 4 occurs that unexpected card pauses stuck, spring hook 4 can also be stirred by inspection hole 11, carry out suitable adjustment, improve maintenance efficiency.

The above is only preferred implementation of the present utility model, protection range of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
