The self-locking device is characterized by comprising a locking sheet and a locking column, wherein the locking sheet is arranged on a leaf; the locking column is arranged on the other leaf; the locking sheet is provided with a limiting groove and a limiting bolt which is arranged in the limiting groove; a fixed end of the locking sheet is provided with a rotating shaft; a free end of the locking sheet is provided with a bent hook; the bent hook at the free end of the locking sheet is an acute-angle bent hook; and the outer surface of the bent hook is a smooth inclined surface. The self-locking device has the advantages of simple structure, reliable locking action, easiness for manual starting and capabilities of finishing self-locking device action after closing of the safety door, preventing accidental opening due to error action, improving the safety of the safety door and guaranteeing the safety for production, and also be applied at other places where mechanical self-locking is required.
Description
Technical field:
The utility model relates to a kind of self-locking device of safety door, and it belongs to a kind of mechanical self-locking device.
Background technology:
The related door of the utility model is to be used for lathe or safety door mechanically.Therefore this type door, does not use the door lock of common implication, but adopts easy locking device owing in use need often to open.But existing locking device can be because lathe or machining vibration or people be maloperation; Cause the unexpected unlatching of protective door; The iron filings or the cooling fluid that might cause processing fly out, and unexpected unlatching of safety door also might cause effect to be lost efficacy, and might cause personal injury.
Summary of the invention:
The purpose of the utility model is to provide a kind of safety door of realizing to close the back and pin automatically, prevents the self-locking device of the unexpected safety door of opening.
A kind of self-locking device of safety door is characterized in that it comprises the locking plate 1 that is arranged on the Yishanmen and is arranged on the lock 2 on other Yishanmen; On described locking plate 1, be provided with stopper slot 4 with place stopper slot limited bolt 3 arranged; Fixed end at described locking plate 1 is provided with a rotating shaft 5, free end band one crotch of said locking plate.
Free end band one crotch of said locking plate is the acute angle crotch, and the external surface of its crotch is a smooth inclined-plane.
Free end band one crotch of said locking plate is the right angle crotch, and the external surface of its crotch is a smooth inclined-plane.
The utility model is simple in structure, and the locking reliable in action is manually opened easy, can accomplish complete door and close up back self-locking device action, and can prevent the unexpected unlatching of misoperation, and the safety that has improved safety door has also ensured the safety of producing.The utility model also can be applied in other other need the occasion of mechanical self-latching.

Fig. 4 be the utility model the user mode structural representation three
The specific embodiment:
Below in conjunction with accompanying drawing 1, Fig. 2, Fig. 3 and Fig. 4, the utility model is further explained:
In the present embodiment, the utility model comprises two parts, is arranged on the locking plate 1 on the Yishanmen and is arranged on the lock 2 on other Yishanmen with part; The utility model is to use the safety door on mechanical device, and this type safety door all has two door leafs.The locking plate of the utility model is arranged on the Yishanmen, and lock 2 is arranged on other Yishanmen.For safety door can be realized automatic blocking when closing, on described locking plate 1, be provided with a stopper slot 4 with place stopper slot limited bolt 3 arranged; Fixed end at described locking plate 1 is provided with a rotating shaft 5, free end band one crotch of said locking plate.In order to make the locking fluent movements of locking plate, free end band one crotch of said locking plate is the acute angle crotch, and the external surface of its crotch is a smooth inclined-plane 12.
Related safety door is parallel door in the prior art in the utility model; Promptly two parallel installations of door leaf when mounted, have stopper slot 4 on the locking plate 1; Locking plate 1 is fixed on the door leaf 6 through rotating shaft 5; And can rotate along rotating shaft 5, limited bolt 3 being housed on the door leaf 6 passing stopper slot 4, the scope that makes locking plate 1 rotate receives the restriction of limited bolt 3 and stopper slot 4.
The automatic blocking process of the utility model has been described like Fig. 2, Fig. 3 and Fig. 4; When door leaf 6 and door leaf 61 close up; Locking plate 1 inclined-plane 12 can 5 rotate rise around the shaft with lock 2 collisions, locking plate 1, after door closes up; Locking plate 1 fastens lock 2 realization self-lockings because action of gravity falls, and can prevent that the maloperation of door from opening.When needs were opened protective door, external force was lifted locking plate and is got final product.Limited bolt 3 and stopper slot 4 when locking state not, the tram that can keep locking plate, excessively upset and can't realize self-locking of locking plates rotation takes place to locking plate 1 in 2 collisions with lock in the time of can preventing that door from closing up simultaneously.
In the present embodiment, free end band one crotch of said locking plate is the right angle crotch, and the external surface of its crotch is a smooth inclined-plane.
Other part and the embodiment 1 of present embodiment are identical.
