Description

A kind of Automatic door bolt

[technical field]

The utility model relates to a kind of keeper, refers in particular to the Automatic door bolt that is contained between the two fan doors.

[background technology]

The patent No. is a kind of keeper of 200520000403.2, and it loads onto this keeper therein on the Yishanmen when installing and using, load onto the keeper push pedal on other Yishanmen.At closing time, by the keeper push pedal the horizontal pushing block that makes after the effect on the keeper is rotated, laterally pushing block promotes the sliding door bolt assembly by vertical catch bar again and slides and realized the purpose of bolt door afterwards.The keeper of this structure is when opening the door, after promoting horizontal pushing block and making it to expose the bolt seat and reset, the sliding door bolt assembly falls down automatically under action of reset spring and realizes opening the door, because in use, the latching that the sliding door bolt assembly often takes place is stuck in the doorframe, at this moment the sliding door bolt assembly just can't fall down under action of reset spring and open the door, so the functional performance of the keeper of this structure is relatively poor, is necessary to improve.

[utility model content]

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of rational in infrastructure, Automatic door bolt that the switch door is smooth and easy and safe and reliable is provided.

In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposals:

A kind of Automatic door bolt, it includes keeper push pedal and the bolt seat that is installed in respectively on the two fan doors, the sliding door bolt assembly is housed in the chute of this bolt seat, the pushing mechanism that can this promotion sliding door bolt assembly slides in this bolt seat is housed in the bottom of this sliding door bolt assembly, this pushing mechanism includes vertical catch bar and horizontal pushing block, and this horizontal pushing block is fixed on this bolt seat by bearing pin and can rotates around this bearing pin; Stretch out from the bolt seat on one side of this horizontal pushing block, and another side is provided with connecting rod, the other end of this connecting rod and vertically catch bar flexible connection, and it is characterized in that: the other end at this vertical catch bar is provided with the grab that can promote and draw this sliding door bolt assembly.

Aforesaid a kind of Automatic door bolt is characterized in that: described sliding door bolt assembly includes latch, slide block, back-moving spring and spring block, and wherein this latch one end is connected with slide block with spring block successively, and the other end exposes from the sliding eye of bolt seat; After this back-moving spring was sleeved on this latch, the one end kept off on this spring block, and the other end keeps off in the chute inwall of this bolt seat; Grab on described vertical catch bar can just be hooked in the hook groove of this slide block.

Aforesaid a kind of Automatic door bolt is characterized in that: described latch includes jackshaft and is socketed in the bolt cover of this jackshaft one end, and the other end of this jackshaft is connected with slide block with spring block successively; On the reeve end of this bolt cover, be provided with arc angling; On this jackshaft, be with stage clip.

Aforesaid a kind of Automatic door bolt is characterized in that: described keeper push pedal is that " [" type should " side of [" type keeper push pedal be to be used to promote the action plate that this horizontal pushing block rotates, and opposite side is the fixed head that is installed on other Yishanmen.

Compared with prior art, 1), the utlity model has following advantage: because when promoting horizontal pushing block and exposing the bolt seat and reset, grab by vertical pushing block can spur the sliding door bolt assembly and fall down and open the door, the latch that the sliding door bolt assembly can not take place is stuck in the doorframe and the phenomenon that can't fall down, so it is of the present utility model rational in infrastructure, safe and reliable; 2), the insertion end of bolt cover is that arc angling exposes the back playing the effect that guiding is inserted doorframe at closing time from the keeper sliding eye, like this at closing time, can successfully be inserted in the doorframe, make close the door more smooth and easy; 3), be half opening " push pedal of [" type keeper is increased by force intensity, can stand from the bigger active force of horizontal pushing block, thereby improve application life of the present utility model.

[specific embodiment]

The utility model is a kind of Automatic door bolt, it includes keeper push pedal 1 and the bolt seat 2 that is installed in respectively on the two fan doors, in the chute 21 of this bolt seat 2, sliding door bolt assembly 3 is housed, the pushing mechanism 4 that can this promotion sliding door bolt assembly 3 slides in this bolt seat 2 is housed in the bottom of this sliding door bolt assembly 3, this pushing mechanism 4 includes vertical catch bar 41 and horizontal pushing block 42, and this horizontal pushing block 42 is fixed on this bolt seat 2 by bearing pin 5 and can rotates around this bearing pin 5; Stretch out from bolt seat 2 on one side of this horizontal pushing block 42, another side is provided with connecting rod 421, the other end of this connecting rod 421 flexibly connects with vertical catch bar 41, is provided with the grab 411 that can promote and draw this sliding door bolt assembly 3 at the other end of this vertical catch bar 41.At closing time, wherein the keeper push pedal 1 on the Yishanmen acts on the also rotation of use on this horizontal pushing block 42, laterally pushing block 42 makes vertical catch bar 41 promote 3 slips of sliding door bolt assembly by the connecting rod on it 421, when the top of sliding door bolt assembly 3 is inserted in the doorframe, finish the process of closing the door.Promote horizontal pushing block 42 expose the bolt seat reset open the door in, grab by vertical catch bar can spur the sliding door bolt assembly and fall down and open the door, the latch that the sliding door bolt assembly can not take place is stuck in the doorframe and the phenomenon that can't fall down, so it is of the present utility model rational in infrastructure, safe and reliable.
