Abstract
A double-chain-type connection device is characterized in that: a bottom plate casing (1) and a casing (7) are internally provided two intermeshed transmission gears (15) with same tooth number modulus, a chain slot (16) is formed among each gear (15), a blocking plate (14) and a shaft (5), a cylindrical pin (3) is fixed between the gear (15) and the blocking plate (14), the end of a chain (8) sleeves the cylindrical pin (3) by a chain ring (13); the end of one shaft (5) is sheathed with a rotary knob (6). Two joints are fixedly connected by a holder, so that the two joints can be simultaneously inserted into insertion holes of a slot plate or simultaneously taken out, and the use flexibility is good. When connection is not needed, the chains and the joints can be drawn back only by rotating the rotary knob, so that the overall appearance of the device can be ensured. The device can be installed in door leaves and door frames, and can also be installed in other two moving objects in order to achieve quick connection and quick detachment.
Description
Technical field
The present invention relates to a kind of two objects can be connected as the chain linkage of bolt structure.
Background technology
Existing keeper is divided into two parts, part with chain and plug is to be generally fixed on doorframe, with the part of jack, being fixed on door leaf and (also can oppositely installing), is that the plug insertion jack by being connected with chain and completing flexibly connects or separated.The chain length of this keeper is fixed, and can not change strength deficiency, more not flexible.While not connecting, the plug being connected with chain hangs from above on doorframe, can collide doorframe and send the sound during switch gate, also can affect the application life of lacquer painting.
Summary of the invention
Object of the present invention is exactly the deficiency existing for solving prior art, provides a kind of chain to elongate or to retract, the chain linkage that two objects can be connected.
Technical solution of the present invention is:
Bottom plate shell with in shell, be provided with that two moduluses are identical with the number of teeth, the gear of the transmission of intermeshing, between each gear and catch and axle, form key way, between gear and catch, be fixed with straight pin, the end of chain is enclosed within on straight pin by chain link; End at a major axis is socketed with knob, and another minor axis is only arranged in bottom plate shell and shell.
Further technical solution of the present invention is:
The diameter of said catch is less than the tip diameter of gear.
Bottom plate shell and shell snapping are integrated, and have the axle bush of back shaft on bottom plate shell and shell.
The end that said shaft extension goes out shell one side is square toes and is socketed with the square hole on knob.
The plug being connected with two chains is fixed on a retainer simultaneously, and two plugs articulate simultaneously or depart from two jacks on corresponding slot board.
Plug spins by self screw rod and nut.
The good effect that the present invention produces is:
Owing to having adopted the structure of chain, bonding strength was doubled than originally, and particularly the mutually despun design of Double-gear engagement, adds the effect of upper knob, chain is stretched out simultaneously or regain simultaneously, and synchronism is good.Two plugs are fixedly connected with a retainer, can make two plugs insert the jack of slot board simultaneously or take out simultaneously, and in use, flexibility is fine.While not needing to connect, only need to take out plug, turning knob can be regained chain and plug, to guarantee the overall appearance of this device.This device both can be arranged on door leaf and doorframe, also can be arranged in other two moving objects to realize quick connection and to depart from fast.

Fig. 1 is structural representation of the present invention.
Fig. 2 is the right view (broken section) of Fig. 1.
Fig. 3 is the structural representation of gear, catch, axle, straight pin and chain.
Fig. 4 is the structural representation of slot board.
The specific embodiment
Below with reference to accompanying drawing, embodiments of the invention are made to detailed description.
Referring to Fig. 1, Fig. 2, the present invention has a bottom plate shell 1 and shell 7, the two snapping is integrated, and two covers is installed in bottom plate shell 1 and shell 7 by gear 15 and the catch 14 of axle 5,4 cross-under, and the space between each gear 15 and catch and axle 5 forms a key way 17.Between gear 15 and catch 14, be designed with straight pin 3, chain 8 one end are socketed in (referring to Fig. 3) on straight pin 3 by chain link 13.The diameter of said catch 14 is slightly less than the tip diameter of gear 15, and the modulus of two gears 15 is identical with the number of teeth, the transmission of intermeshing.Said axle the 5, the 4th, one is long and the other is short two axles, shell 7 is stretched out in one end of major axis, and its termination is designed to square toes, and inserts in the square hole of knob 6; Another axle is minor axis 4, is only connected in the axle bush 2 between bottom plate shell 1 and shell 7.The other end of two chains 8 passes bottom plate shell 1 and nut 10 sockets, and plug 9 spins by self screw thread and nut 10, is connected with a retainer 11 between two plugs 9.
Referring to Fig. 4, the plug 9 that has jack 16, two chain 8 ends completely corresponding with two plugs 9 on slot board 12 can be articulated in jack 16 or simultaneously simultaneously and take out from jack 16 under the effect of retainer 11.
When two objects need to be connected, only need hand to hold retainer 11 plug 9 is articulated in jack 16.If do not needed to connect, with hand, retainer 11 is upwards lifted and can make plug 9 take out from jack 16 equally, complete and depart from action.
