Description
Technical field
The utility model relates to door lock technical field, more specifically to a kind of automatic locking protective device of unblanking by opal of preventing.
Background technology
As shown in Figure 1, after general people shut the door after you, people indoor by the rotary door handgrip A1 body A3 that knocks at the door, have at present that a kind of to utilize manipulator A2 to stretch into indoor from the opal A31 of door body A3, allow hook portion hook before manipulator A2 door handgrip A1 or pressing door handgrip A1 just can open a broken chamber less than one minute and enter to carry out stealthy activity.In order to prevent that robber from unblanking by opal, the hand that must design a mechanism cannot be opened the device of door lock.
Summary of the invention
The purpose of this utility model is exactly the deficiency for prior art, and a kind of protective device of unblanking by opal of preventing is provided, and it can prevent that robber from opening door lock by manipulator, plays antitheft function.
Technology solution of the present utility model is as follows:
Prevent the protective device of unblanking by opal, comprise door lock housing and door locking handle, on door lock housing, form slotted hole, traveller sleeve is in this slotted hole, on collar, form sorting hole and locking hole, between sorting hole and locking hole, form transition cylindrical void, two ends of transition cylindrical void communicate with sorting hole and locking hole respectively;
Two ends of collar are fixed on door lock housing, and sorting hole, locking hole and transition cylindrical void are facing to slotted hole, and traveller is placed in sorting hole, locking hole and transition cylindrical void;
Stay is fixed in the rotating shaft of door locking handle, forms the breach of U font on stay, and breach is facing to traveller.
On described door lock housing, be fixed with the first bolt and the second bolt, on two ends of collar, form respectively left lasso and right lasso, left lasso and right lasso difference sleeve are on the first bolt and the second bolt, nut is screwed onto on the first bolt and the second bolt and is pressing two ends of collar, on traveller, be bolted with nut, nut is placed in the inner side of door lock housing, forms cap portion on traveller, and cap is deployed in the outside of door lock housing.
On described stay, form arcuation cylindrical void, the second bolt is placed in this arcuation cylindrical void.
The beneficial effects of the utility model are:
It can prevent that robber from opening door lock by manipulator, plays antitheft function.

detailed description of the invention:
Embodiment: see shown in Fig. 2 to 7, prevent the protective device of unblanking by opal, comprise door lock housing 1 and door locking handle 2, on door lock housing 1, form slotted hole 1a, traveller 3 sleeves are in this slotted hole 1a, on collar 4, form sorting hole 41 and locking hole 42, between sorting hole 41 and locking hole 42, form transition cylindrical void 43, two ends of transition cylindrical void 43 communicate with sorting hole 41 and locking hole 42 respectively;
Two ends of collar 4 are fixed on door lock housing 1, and sorting hole 41, locking hole 42 and transition cylindrical void 43 are facing to slotted hole 1a, and traveller 3 is placed in sorting hole 41, locking hole 42 and transition cylindrical void 43;
Stay 5 is fixed in the rotating shaft 21 of door locking handle 2, forms the breach 51 of U font on stay 5, and breach 51 is facing to traveller 3.
On described door lock housing 1, be fixed with the first bolt 6 and the second bolt 7, on two ends of collar 4, form respectively left lasso 44 and right lasso 45, left lasso 44 and right lasso 45 difference sleeves are on the first bolt 6 and the second bolt 7, nut is screwed onto on the first bolt 6 and the second bolt 7 and is pressing two ends of collar 4, on traveller 3, be bolted with nut, nut is placed in the inner side of door lock housing 1, forms cap portion 31 on traveller 3, and cap is deployed in the outside of door lock housing 1.
On described stay 5, form arcuation cylindrical void 52, the second bolts 7 and be placed in this arcuation cylindrical void 52.
Operating principle: as shown in Figure 6, traveller 3 is to be generally arranged in sorting hole 41, and now traveller 3 separates with breach 51, and door locking handle 2 can rotate together with stay 5, now utilizes the manipulator can be by door-lock opening.
As shown in Figure 7, upwards push traveller 3, traveller 3 slips over transition cylindrical void 43 and enters in locking hole 42 and traveller 3 snaps in breach 51, stay 5 and door locking handle 2 all cannot rotate, now utilize manipulator cannot promote indoor door locking handle 2, so just played the effect that prevents from utilizing by opal manipulator opening door lock.
If want to get back to Fig. 6 state from Fig. 7 state, push traveller 3 downwards, traveller slides in sorting hole 41 along slotted hole 1a and transition cylindrical void 43.
