Description

Automatic connecting ring bolt

The utility model belongs to the part technical field that door and window or wing are used, and is a kind of a chain of automatic pinning.

Existing double door or multiple leaf door latch mode need before latching Yishanmen is fixed with latch or the back that latches is fixed with the string bar, use inconvenience, and barrier propterty is relatively poor.

The purpose of this utility model is a kind of a chain of automatic pinning of design, and two-door (or multi-door) be the energy automatic pinning when closing, can the while automatic pinning during with tongue door lock adapted.

The technical scheme that the utility model adopted is, utilizes lever principle, establishes the pressure tongue at an end of shank, establishes plug at the other end, lifts to drive to stretch under the plug after pressing tongue to be touched by first door leaf and inserts another door leaf; First door leaf is opened, and presses tongue to be subjected to stretch out under the effect of torsion spring, and plug lifts, and withdraws from other Yishanmen, the latch voluntarily with the switch of door.

Reach the structural representation that example further specifies a chain of automatic pinning of the utility model in conjunction with the accompanying drawings.

Fig. 1 is the structural representation of a chain of automatic pinning of the utility model;

Fig. 2 is that the A-A of Fig. 1 is to view.

Referring to Fig. 1, Fig. 2, the utility model automatic pinning comprises shell 7, and shank 3 is pressed tongue 5, plug 8, and torsion spring 1 is inserted dead top flat 6, bearing pin 2, fastener hole 4, pearl 9 is bumped in the location.Shank 3 is bearing in the shell 7 by bearing pin 2, and an end of shank 3 is established and pressed tongue 5, establishes plug 8 at the other end, and shell 7 is provided with presses tongue extending port and plug extending port, is pressing tongue shank 3 upsides on one side to be provided with torsion spring 1, is provided with at its downside and inserts dead top flat 6.For the ease of by the location of Yishanmen in addition of pin, on the shell of plug one side, be provided with the location and bump pearl 9.On shell, offer fastener hole 4.

This automatic pinning is installed on the middle upper door frame of two fan crack between a door and its frames by fastener hole 4, and on by other Yishanmen of pin, offers jack.Close earlier by the Yishanmen in addition of pin, locate, this moment, the plug of automatic pinning did not move, when pass Yishanmen (the tongue lock is housed) is lived with another fan door lock, the pressure tongue of Yishanmen compressing automatic pinning lifts in the retraction shell, make and stretch under the plug in the jack that inserts other Yishanmen, two fan doors are automatic mortise lock.When opening the door, push Yishanmen earlier open, press tongue to stretch out under the effect of torsion spring, plug withdraws from the retraction shell automatically from inserting in the hole, and Yishanmen can be opened in addition.

This automatic pinning of the present utility model is suitable for two fan or multiple leaf door mortise locks.Promptly automatic pinning of the peace of the upper door frame in the middle of each crack between a door and its frame is only pacified lock on Yishanmen, can reach a chain of effect of mortise lock automatically, when opening the door, still opens the Yishanmen that peace is locked earlier, and other each fan door can be opened successively.

If only open Yishanmen, other each fan door is not opened, and can reverse and insert dead top flat 6, presses tongue 5 by jack-up, and plug 8 promptly is inserted in the jack forever.

This automatic connecting ring bolt of the present utility model is compared with existing latch mode, has automatic pinning, automatically releases slottingly, or inserts dead function and advantage easy to use.
