Description

Protective gewel hasp for door

The utility model relates to a kind of Protective gewel hasp for door, is applicable to the protective device that limiting door is opened, and belongs to a burglary-resisting installation technical field.

At present, the needs along with the raising of living standards of the people and production, business activity require more and more higher to the door of household and office space, the decoration of window.And the complexity of social security requires door, window all to possess anti-theft feature.The antitheft requirement that two aspects are arranged of people's opposite house, window: require its theftproof performance good on the one hand, require to have decorative effect on the other hand.In the actual life, people use theftproof lock or common Theftproof bolt usually.The anti-theft effect of theftproof lock is better, but has complex structure, cost height, manufacturing and difficult shortcoming is installed; Though common enamel latch can play certain protective action, exist theftproof performance poor, ornamental poor, use inconvenient shortcoming.

The purpose of this utility model is for a kind of Protective gewel hasp for door is provided, and this Protective gewel hasp for door is simple in structure, has antitheft simultaneously and decorative effect.

The purpose of this utility model can reach by taking following measure: Protective gewel hasp for door, its design feature is: be made of rubber, movable clasp, Button Block, movable controller, Button Block can be fixed on the doorframe, one side of movable clasp by mobility controls be connected with Button Block, another side is fixedlyed connected with rubber and can with the overlapping edges of door, movable controller can be controlled movable button and be hooked in closure or openness in the 0 °～45 degree, and rubber is arranged on the crotch end of movable clasp.

The purpose of this utility model also can reach by taking following measure:

Movable controller is made of two springs and two bolt pins, one end of described spring is fixed on the Button Block, the other end contacts with bolt pin is movable, bolt pin couples together movable clasp, Button Block that to make movable clasp be the rotation that fulcrum is made certain angle with two bolt pins, and the junction of bolt pin and Button Block stays certain space that movable clasp can be moved within the specific limits.

Compared with prior art, the utlity model has following outstanding effect:

1. be fixed on the doorframe owing to Button Block, the moving fulcrum of spring and bolt pin formation activity clasp, generally movable clasp can not rotate along described fulcrum, only stirring movable clasp just can make movable clasp not have fulcrum to rotate, be movable clasp can only forward open, can not reverse opening, thrust is much all can not be from opening door, therefore outdoors, the utlity model has stronger crashproof, protecting against shock ability, anti-theft effect is good.

2. because movable clasp relies on rubber will withstand fastening when closed, therefore, can strengthen contacting of clasp and door-plate on the one hand, can effectively protect door-plate not to be damaged on the other hand.

3. simple in structure, manufacturing and easy to use, with low cost, good looking appearance.

Below in conjunction with accompanying drawing the utility model is described in detail:

Fig. 1 is a structural front view of the present utility model.

Fig. 2 is the A-A cut-away view of Fig. 1.

Fig. 3 is a structure vertical view of the present utility model.

Fig. 1, Fig. 2 and Fig. 3 constitute embodiment 1 of the present utility model.As can be seen from Figure 1, present embodiment is made of rubber 1, movable clasp 2, Button Block 3, movable controller 4.As can be seen from Figure 2, movable controller 4 is made of two springs 5 and two bolt pins 6, one end of described spring 5 is fixed on the Button Block 3, the other end and bolt pin 6 movable contacts, bolt pin 6 couples together movable clasp 2, Button Block 3 that to make movable clasp 2 be the rotation that fulcrum is made certain angle with two bolt pins 6, bolt pin 6 stays certain space that movable clasp 2 is struck within the specific limits with the junction of Button Block 3, causes movable clasp 2 energy closure or openness.

The operating principle of present embodiment is:

From Fig. 1; Fig. 2; Fig. 3 as can be known; Button Block 3 is provided with the Long Circle hole; the diameter of this boring ratio bolt pin is big slightly; move when making things convenient for bolt pin 6 to make the Protective fastener closure or openness; with screw described Button Block 3 is fixed on the doorframe; one side of movable clasp 2 is by bolt pin 6; spring 5 is connected with Button Block 3; another side is by the overlapping edges of rubber 1 with door; bolt pin 6 and the effect formation moving fulcrum of Button Block 3 through spring 5; make movable clasp 2 closure or openness in 0 °～45 degree; rubber 1 is arranged on the crotch end of movable clasp 2; rely on rubber 1 will withstand fastening during activity clasp 2 closures; therefore; can strengthen on the one hand contacting of clasp and door-plate, can effectively protect door-plate not to be damaged on the other hand.Because Button Block is fixed on the doorframe, the moving fulcrum of spring and bolt pin formation activity clasp, generally movable clasp can not rotate along described fulcrum, only stirring movable clasp certain distance just can make movable clasp not have fulcrum to rotate, be movable clasp can only forward open, can not reverse opening, thrust is much all can not be from opening door outdoors.
