Abstract
A kind of double-chain linkage, it is characterized in that being provided with the identical and gear (15) of transmission of intermeshing of two number of teeth moduluses in bottom plate shell (1) with shell (7), key way (16) is formed between each gear (15) and catch (14) and axle (5), be fixed with straight pin (3) between gear (15) and catch (14), the end of chain (8) is enclosed within straight pin (3) by chain link (13); Knob (6) is connected in the end sleeve of an axle (5).Two joints retainer is fixedly connected with, and two joints can be made to insert the jack of slot board simultaneously or take out simultaneously, use middle flexibility fine.When not needing to connect, only need turning knob chain and joint can be regained, to ensure 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 connecting fast and departing from fast.
Description
Technical field
The present invention relates to a kind of chain linkage as bolt structure that two objects can be connected.
Background technology
Existing keeper is divided into two parts, part with chain and plug is generally be fixed on doorframe, part with jack is then fixed on door leaf and (also can oppositely installs), is to complete by inserting jack with the plug that chain connects to flexibly connect or be separated.The chain length of this keeper is fixed, and can not change, strength deficiency, more not flexible.When not connecting, the plug be connected with chain hangs from above on doorframe, can collide doorframe and send the sound, also can affect the application life of lacquer painting during switch gate.
Summary of the invention
Object of the present invention is exactly the deficiency existed 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:
In bottom plate shell with shell, be provided with that two moduluses are identical with the number of teeth, the gear of transmission of intermeshing, form key way between each gear and catch and axle, be fixed with straight pin between gear and catch, the end of chain is enclosed within straight pin by chain link; Be connected to knob in the end sleeve of a major axis, 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 bottom plate shell and shell have the axle bush of back shaft.
The end that said shaft extension goes out shell side is square toes and is socketed with the square hole on knob.
The plug be connected with two chains is fixed on a retainer simultaneously, and two jacks on two plugs and corresponding slot board mount simultaneously or depart from.
Plug is spun by self screw rod and nut.
The good effect that the present invention produces is:
Owing to have employed the structure of chain, bonding strength was doubled than originally, particularly the mutually despun design of Double-gear engagement, and add the effect of upper knob, make chain stretch out simultaneously or regain simultaneously, synchronism is good.Two plugs retainer is fixedly connected with, and two plugs can be made to insert the jack of slot board simultaneously or take out simultaneously, use middle flexibility fine.When not needing to connect, only need take out plug, chain and plug can be regained, to ensure the overall appearance of this device by turning knob.This device both can be arranged on door leaf and doorframe, also can be arranged in other two moving objects to realize connecting fast and departing from fast.

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.
Detailed description of the invention
Below with reference to accompanying drawing, detailed description is made to embodiments of the invention.
See Fig. 1, Fig. 2, the present invention has a bottom plate shell 1 and shell 7, the two snapping is integrated, and is provided with two covers by the gear 15 of axle 5,4 cross-under and catch 14 in bottom plate shell 1 and shell 7, 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 is socketed in (see 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, transmission of intermeshing.Said axle 5,4 is that 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 is socketed with nut 10, and plug 9 is spun by self screw thread and nut 10, is connected with a retainer 11 between two plugs 9.
See Fig. 4, the plug 9 slot board 12 having jack 16, two chain 8 end completely corresponding with two plugs 9 can be articulated in jack 16 or simultaneously simultaneously and take out from jack 16 under the effect of retainer 11.
When needing two objects to connect, hand-held retainer 11 is only needed to be articulated in by plug 9 in jack 16.If do not needed to connect, with hand retainer 11 upwards being lifted equally and plug 9 can be made to take out from jack 16, completing disengaging action.
Claims (6)
