The utility model has the advantages that the structure is simple and reasonable, whole beautiful appearance of the door is not damaged, the function of built-in pin can be played, and the utility model is crashworthy and pickproof, so the anti-theft performance of the door is enhanced.
Description
The utility model relates to a kind of mechanism, particularly a kind of door leaf built-in pin mechanism.
Existing security door is generally all strengthened theftproof performance on door lock one side of door leaf, often ignored the theftproof performance of door leaf chain one side, often gives bad person's opportunity.
It is a kind of simple and reasonable that the purpose of this utility model is to provide, and can play crashproof pick-proof effect, the door leaf built-in pin mechanism of the anti-theft feature of reinforced door.
The purpose of this utility model can reach by following measure: the utility model comprises tip bolt, axle, shelves post, pin bolt frame piece, and pin bolt frame piece is fixed on the doorframe, and axle and shelves post are fixed on the pin bolt frame piece, and the activity of tip bolt is loaded on the axle.
The purpose of this utility model can also reach by following measure: have emptiness avoiding hole on the doorframe, tip bolt can stretch out in outside the doorframe by emptiness avoiding hole.Tip bolt is provided with manhole, and passes through the manhole movable set on axle.Pin bolt frame piece is welded on the doorframe.
Fig. 1 is in the structural representation of collapsed state for the utility model;
Fig. 2 is in the structural representation of the state of stretching out for the utility model;
Structural representation when Fig. 3 is used for the utility model and door leaf.
The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):
With reference to Fig. 1～Fig. 3, the utility model is made up of tip bolt 1, axle 2, shelves post 3, pin bolt frame piece 4.Pin bolt frame piece 4 is welded on the doorframe 5; Axle 2 and shelves post 3 are located on the pin bolt frame piece 4, become a fixed body; Tip bolt 1 is provided with manhole, and passes through the manhole movable set on axle 2, can rotate around axle 2; 1 position-limiting action of shelves 3 pairs of tip bolts of post.Have emptiness avoiding hole 5-1 on the doorframe 5, tip bolt 1 can stretch out or returns from emptiness avoiding hole 5-1.
Close in front of the door, tip bolt 1 is rotated show, promptly a distal process of tip bolt 1 goes out outside the doorframe 5; Close behind the door, tip bolt 1 plays dark tip effect, can crashproof pick-proof, strengthened the theftproof performance of door.After opening the door, tip bolt 1 is swung in, promptly tip bolt 1 is hidden in the doorframe 5, projection is not arranged, keep overall appearance from visually seeing doorframe.
The utility model has following advantage compared to existing technology: simple and reasonable, both can Play dark tip effect, crashproof pick-proof, the theftproof performance of reinforced door, can not destroy again the door integral body Attractive in appearance; Being fit to various antitheft doors uses.
