Abstract
The utility model relates to a door bolt which comprises a bolt base. The utility model is characterized in that a sliding door bolt component is arranged in the bolt base, and a pushing mechanism which can push the sliding door bolt component to slide in the bolt base is arranged below the sliding door bolt component and comprises a longitudinal pushing bar and a transverse pushing block which is fixed to the bolt base by a pin shaft and can rotate around the pin shaft. One side of the transverse pushing block extended with a pushing bar extends outside the bolt base, and the other end of the pushing bar is movably connected with the longitudinal pushing bar with the other end provided with a roller which is in contact with the bottom of a slide block. The door bolt has simple structure, labor saving when the door is locked, convenient operation, safety, theft prevention and convenient installation. The transverse pushing bar can be rotated by means of the force of closing the door to make the bolt post plugged in a bolt post hole of the door frame automatically after the door is closed.
Description
[technical field]
The utility model relates to a kind of keeper.
[background technology]
At present, generally the pushing formula double door of Shi Yonging is to load onto keeper on the Yishanmen therein, its when closing the door or open the door all must with on the hand push or the hitching post of leaving behind can realize.So in use just brought certain trouble.Close and forget upward bolt behind the door sometimes, in case forget upward bolt, door just is easy to be opened, and does not at this moment just have antitheft effect; Simultaneously, have certain clearance between the two fan doors, the thief also adopts some means that keeper is opened easily.Also have the complex manufacturing of some keepers, operation is many, and cost of production is higher, complex structure.
[summary of the invention]
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of easy to use, and theftproof performance is good, the keeper that cost of production is low.
The purpose of this utility model is achieved in that
A kind of keeper, comprise the bolt seat, it is characterized in that in the bolt seat, being equipped with the sliding door bolt assembly, be equipped with in the bottom of sliding door bolt assembly and can promote the pushing mechanism that the sliding door bolt assembly slides in the bolt seat, pushing mechanism includes vertical catch bar and horizontal pushing block, laterally pushing block is fixed on the bolt seat by bearing pin, and horizontal pushing block can be rotated around bearing pin; Laterally stretch out outside the bolt seat on one side of pushing block, laterally is being extended with catch bar on the pushing block, the other end of catch bar and vertically catch bar flexible connection, and vertically the other end of catch bar is provided with roller, and roller contacts with the bottom of slide block.
Aforesaid a kind of keeper is characterized in that the sliding door bolt assembly by keeper, slide block, and back-moving spring is formed, and keeper is connected with slide block, and back-moving spring is contained on the keeper, and the one end is stuck on the slide block, and the other end is stuck on the bolt seat.
Aforesaid a kind of keeper is characterized in that described keeper comprises the jackshaft that is connected with slide plate, is with stage clip on jackshaft, is with the bolt cover on the other end of jackshaft.
Aforesaid a kind of keeper is characterized in that the centre of bolt seat is provided with chute, and the sliding door bolt assembly is contained in the chute.
The beneficial effects of the utility model are: simple in structure, laborsaving during the bolt door, handiness at closing time, reaches by the just rotatable horizontal catch bar of the power of the door that will close and to close behind the door that hitching post can be inserted in the hitching post hole of doorframe automatically; And the utility model safe antitheft, easy for installation.

[specific embodiment]
A kind of keeper comprises bolt seat 1, and sliding door bolt assembly 2 is housed in bolt seat 1, is equipped with in the bottom of sliding door bolt assembly 2 and can promotes the pushing mechanism 3 that sliding door bolt assembly 2 slides in the bolt seat.
The centre of bolt seat 1 is provided with chute 4, is provided with hitching post fixing hole 5 in the upper end of chute 4, and the bottom is provided with pushing mechanism installing hole 6, and sliding door bolt assembly 2 is contained in the chute 4, and pushing mechanism 3 is contained in the pushing mechanism installing hole 6.
Sliding door bolt assembly 2 is by keeper 7, slide block 8, and back-moving spring 9 is formed, and keeper 7 is connected with slide block 8, and keeper 7 pierces into hitching post fixing hole 5, and back-moving spring 9 is contained on the keeper 7, and the one end is stuck on the slide block 8, and the other end is stuck on the bolt seat 1.In the time of in sliding door bolt assembly 2 is contained in chute 4, because slide block 8 can be pushed mechanism 3 and promote, keeper 7 can be stretched out inject in the bore trepanning be contained on the doorframe, or under the effect of back-moving spring 9, withdraw, thereby make Automatic door bolt the bolt door and the two states of bolt door not occur.
Described pushing mechanism 3 promotes the slip of slide block 8 in chute 4 in the bottom of slide block 8 by it.Pushing mechanism 3 includes vertical catch bar 10 and horizontal pushing block 11.Laterally pushing block 11 is fixed on the bolt seat 1 by bearing pin 12, and horizontal pushing block 11 can be rotated around bearing pin 12; Laterally stretch out outside the bolt seat 1 on one side 13 of pushing block 11, laterally be extended with catch bar 14 on the pushing block 11, the other end of catch bar 14 and vertically catch bar 10 flexible connections, vertically the other end of catch bar 10 is provided with roller 15, roller 15 can roll in chute 4, and contacts with the bottom of slide block 8.The lower end of catch bar 11 also is provided with a limit shaft 16 at column base, and when slide block 8 resetted under the effect of back-moving spring 9, limit shaft 16 can withstand on the rear end of catch bar 11, makes vertical catch bar 10 and catch bar 14 keep forming " people " shape.When external force promotes one side 13 of horizontal catch bar 11, laterally catch bar 11 rotates around bearing pin 12, promoting vertical pushing block 10 by catch bar 14 moves to the upper end of chute 4, and roller 15 promotion slide blocks 8 are moved to the upper end of chute 4, also just make vertical catch bar 10 and catch bar 14 in a straight line, thereby sliding door bolt assembly 2 is played a role.
Described keeper 7 comprises the jackshaft 20 that is connected with slide plate 8, is with stage clip 21 on jackshaft 20, is with bolt cover 22 on the other end of jackshaft 20.
