Description
Technical field
The present invention relates to a kind of field of switches, more particularly to a kind of safety switch.
Background technology
Switch be it is a kind of make the electric elements of current interruptions or conducting in circuit, and the structure type of existing switch is also
It is varied, it is widely used in the middle of various electrical equipment and equipment.For existing switch, most of its only possesses
Basic break-make control function, and it cut-offs electricity and is required to be operated manually, and this problem brought is when electrical equipment, equipment etc.
When falling or exist strenuous vibration skew, switch now can not disconnect automatically, so the circuit in equipment is still within leading
Understanding and considerate condition, this can also leverage security when electrical equipment, equipment etc. are used.
The content of the invention
The present invention proposes a kind of safety switch, and solving in the prior art can not when equipment is fallen or strenuous vibration offsets
Power-off in time and cause the problem of potential safety hazard.
The technical proposal of the invention is realized in this way：
A kind of safety switch, including housing, the switch body that is contained in the housing and one end are outside the other end in housing
Be exposed to the control-rod outside housing, the switch body is contained in housing, its side have multiple extend housing it is outer and with it is to be controlled
The contact chip of electrical equipment electrical connection, the switch body is additionally provided with an operation button in case inside, and the control-rod is located at the behaviour of switch body
Make the side of button, the control-rod outwardly forms an at least projection in the side wall in housing, the projection is interior with housing
One is connected between wall and orders about the compression spring that control-rod is displaced outwardly, the electrical equipment to be controlled is resisted against control-rod positioned at shell
External end its make the side wall being located in housing simultaneously against operation button to realize electrical equipment to mobile compression spring in housing
It is open-minded.
Preferred scheme is, the switch body is provided with a bar shaped shell fragment, one end of the bar shaped shell fragment be fixed on switch body in
Position below operation button, the other end is the free end extended obliquely in the trend for being gradually distance from operation button, the control
Bar processed is to the free end that bar shaped shell fragment can be compressed when being moved in housing.
Preferred scheme is that the control-rod forms one and is used for against behaviour in the side of the end respective operations button in housing
Make button against inclined-plane, should be the side near operation button by control-rod from inside to outside in gradually tapered against inclined-plane
Inclined-plane.
Preferred scheme is that the control-rod forms one and is used for against bar in the side of the end respective operations button in housing
The free end of shape shell fragment against inclined-plane, should against inclined-plane be by close the bar shaped shell fragment of control-rod side from inside to outside in by
Gradually the inclined-plane for contracting.
Preferred scheme is that the safety switch also includes the indicator lamp electrically connected with contact chip, and the indicator lamp is located at housing
It is interior and its head end is extended hull outside.
Beneficial effects of the present invention are：
Safety switch of the invention by electrical equipment suppress control-rod and connect it, when by vibrations incline or run into it is special
When situation is fallen, thus cancel to control-rod against and control-rod is removed to being moved outside housing in the presence of the compression spring
Compacting of the pin control-rod to operation button, and then the closing of safety switch is realized, the generation of unexpected situation is prevented, improve safety
Property.

Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
As shown in figure 1, the safety switch includes that housing 10, the switch body 20 being contained in the housing 10 and one end are located at shell
The other end exposes to the control-rod 30 outside housing 10 in body 10.
The side of the housing 10 has an opening 11.The switch body 20 is contained in housing 10, and its side is stretched with multiple
Contact chip 21 that is outer to housing 10 and being electrically connected with electrical equipment to be controlled, the switch body 20 is additionally provided with an operation in the inner side of housing 10
Button 22.The switch body 20 is provided with a bar shaped shell fragment 36, one end of the bar shaped shell fragment 36 be fixed on switch body 20 in operation by
The position of the lower section of button 22, the other end is the free end extended obliquely in the trend for being gradually distance from operation button 22.The bar shaped bullet
The free end of piece 36 is higher than operation button.The control-rod 30 is to the free end that bar shaped shell fragment 36 can be compressed when being moved in housing 10
Make the pressing operation button 22 of bar shaped shell fragment 36.
The control-rod 30 is arranged in the side of the operation button 22 in the opening 11 of the housing 10 and positioned at switch body 20.Should
One end of control-rod 30 is located in housing 10 through opening 11, and the other end is exposed to outside housing 10.The control-rod 30 is in housing 10
The side of the operation button 22 of interior end correspondence switch body 20 forms one to be used for against bar shaped shell fragment 36 against inclined-plane 31, should
It is in from inside to outside gradually tapered inclined-plane to be formed by the side of the close operation button 22 of control-rod 30 against inclined-plane 31.The control
Bar 30 outwardly forms an at least projection 35 in the side wall in housing 10.It is connected between the projection 35 and the inwall of housing 10
One orders about the compression spring 33 that control-rod is displaced outwardly.The compression spring 33 by projection 35 bottom along control-rod 30 outboard end
Direction extension is mutually fixed as the inwall of housing 10.
Please refer to Fig. 2, when using, electrical equipment is resisted against on the outboard end for exposing to housing 10 of control-rod 30, make
To being moved in housing 10, against inclined-plane 31, gradually against bar shaped shell fragment 36, pressing operation button 22 connects it to control-rod 30,
So that electrical equipment is powered；When electrical equipment is inclined or run into special circumstances by vibrations falls, so that electrical equipment departs to control-rod
Against control-rod 30 cancels the operation button 22 to switch body 20 in the presence of compression spring 33 to being moved outside housing 10
Compacting automatically power off electrical equipment, so as to prevent the generation of fortuitous event, strengthen security.
During specific implementation, the safety switch can also be electrically connected with an indicator lamp with contact chip 21, and the indicator lamp extends housing
Outside, for showing the break-make of its electric equipment.During specific implementation, the control-rod 30 is to the operation button 22 of switch body
The situation against inclined-plane 31 of the present embodiment is not limited to against structure, bar shaped shell fragment 36 can be also not provided with, only by against inclined-plane
31 compress operation button 22；Also this can not be set against inclined-plane 31, bar shaped shell fragment 36 is only compressed by control-rod 30.
Presently preferred embodiments of the present invention is the foregoing is only, is not intended to limit the invention, it is all in essence of the invention
Within god and principle, any modification, equivalent substitution and improvements made etc. should be included within the scope of the present invention.
