Background technology
Existing limit switch, which also has product and props up spacing be blocked in when being hit with metal link rod of action link rod, to be produced
Noise;The moving plate seat being connected with connecting shaft easily loosens, cause also to produce under without service condition disconnection, close it is unstable existing
As;At the external connection at top only under not wiring condition can use protective cover, need to remove protective cover under wiring condition so that compared with
Run into interference source in complicated circuit and make product can not normal work the problems such as.
The presence of above mentioned problem causes existing limit switch normally to work, and mounting process is more multiple
Miscellaneous, cost consumption is also larger.
Utility model content
The purpose of this utility model is to provide the limit switch device that a kind of suitable elevator is used, above-mentioned existing effectively to overcome
There is the deficiency of technology.
To achieve these goals, the technical solution adopted in the utility model is:What a kind of suitable elevator was used spacing opens
Device, including switch box body, rotating shaft, connecting shaft, roller and rotating shaft connecting rod are closed, the switch box body is fixedly mounted on box body installation
On seat, provided with movable contact spring, movable contact spring seat and static contact in its switch enclosure body, rotating shaft is installed in switch enclosure body, in switch enclosure
Wire access holes seat resetting-mechanism is additionally provided with body, its resetting-mechanism is located at rotating shaft;The rotating shaft is fixed by screw
It is connected with movable contact spring seat;Roller is installed on the connecting shaft;One end of the rotating shaft connecting rod is connected with resetting-mechanism, the other end
It is connected by rotating shaft with roller.
It is preferred that, spacing stop is additionally provided with the box body mounting seat, its spacing stop is positioned at the lower section of rotating shaft connecting rod.
Further, the spacing stop is provided with liftable stop head, and it stops that head is located at the lower section of rotating shaft connecting rod.
Further, the roller is made up of rubber, and back-up ring is provided with roller, and its roller passes through back-up ring with rotating shaft connecting rod
It is fastened on connecting shaft.
Further, the top of the wire access holes seat is provided with dust cover.
Using the utility model of the technical program, its advantage is:Limit switch device of the present utility model, due to opening
The setting of movable contact spring in box body, movable contact spring seat and static contact is closed, therefore can make that the stability between part is good, reliability is high;Due to
The setting of wire access holes seat and dust cover, therefore the present apparatus again can not be with dust-proof by external interference;Due to the setting of back-up ring, because
This has saved cost of parts, easy for installation;Due to it is spacing stop and stop head setting, therefore effectively reduce hit send make an uproar
Sound.Limit switch device of the present utility model has not to be influenceed by dust, greasy dirt and environment temperature, and being quick on the draw safety can
Lean on, the advantages of service life is long.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Referring to Fig. 1, limit switch device of the present utility model, including switch box body 10, rotating shaft 20, connecting shaft 30, roller 40
With rotating shaft connecting rod 50, the switch box body 10 is fixedly mounted in box body mounting seat 11, and it, which is switched, is provided with dynamic touch in box body 10
Piece, movable contact spring seat and static contact, rotating shaft 20 is provided with switch box body 10, and wire access holes are additionally provided with switch box body 10
12 resetting-mechanisms 60 of seat, its resetting-mechanism 60 is located at rotating shaft 20;The rotating shaft 20 has been tightly connected with dynamic touch
Bar;Roller 40 is installed on the connecting shaft 30;One end of the rotating shaft connecting rod 50 is connected with resetting-mechanism 60, and the other end leads to
Rotating shaft 20 is crossed to be connected with roller 40.Spacing stop 13 is additionally provided with the box body mounting seat 11, its spacing stop 13 is located at rotating shaft
The lower section of connecting rod 50.The spacing stop 13 stops first 15 provided with liftable, and it stops that first 15 are located at rotating shaft connecting rod
50 lower section.The roller 40 is made up of rubber, and back-up ring 41 is provided with roller 40, and its roller 40 passes through with rotating shaft connecting rod 50
Back-up ring 41 is fastened on connecting shaft 30.The top of the wire access holes seat 12 is provided with dust cover 14.
