Abstract
The utility model relates to a theft proof chain which comprises a fixed base, a chain connecting device and a connecting base. The utility model is characterized in that the T shape inserting heat of the heave of the connecting device is sleeved with the spring and a blocking ring; and the side of the sliding groove which is close to the hole is provided with a baffle block. The utility model can solve the art problem that the separating of connecting device of the sliding groove of the connecting base caused by the round surging of the chain.
Description
Technical field:
The utility model is about the door and window part, particularly about a kind of door chain.
Background technology:
For preventing that the worthless fellow in the society from visiting to plunder, various antitheft construction equipments arise at the historic moment, and select for use for the user.Door chain is exactly an a kind of antitheft apparatus wherein commonly used.Though existing door chain profile is different, structure is the same.Its chain one end is fixed in the holder that is arranged on the doorframe, and the other end then is provided with a connector.This connector has a T-shaped scarf joint that protrudes.The relevant position is provided with the Connection Block of a band chute on door in addition, is provided with the hole that enters greater than the chute width at this chute end place.During use, with the scarf joint of connector aim at enter the hole and insert after, half-twist can embed the venturi portion of scarf joint in the chute and move again.The aperture that the length of chain just can limiting door like this, prevent that the outsider from thrusting oneself in, but there is a potential hidden danger in existing this door chain, promptly when door during by pushing and shoving with sudden force back and forth, chain is beated vibration, move and rotate thereby drive connector, therefore make most probably connector automatically from the chute end enter the hole, lost the effect swarmed into of preventing.And pushing and shoving with sudden force back and forth of door can not take place when the outsider is refused unavoidably.In addition, holder and Connection Block are the entity foundry goods, and be many with material, weight is big.
Summary of the invention:
The purpose of this utility model is to provide a kind of door chain, to solve the technical problem that its connector is beated because of chain vibrates back and forth and deviate from the chute by Connection Block that causes.Secondly for solving its many with material, that weight is big problem.
The technical scheme that the utility model solves the problems of the technologies described above is as follows:
A kind of door chain comprises holder, chain, connector and Connection Block, it is characterized in that: be equipped with spring and back-up ring on the thin neck of the T shape scarf joint that this connector protrudes; The chute side that this Connection Block inner chamber closely enters the place, hole is provided with block.
Above-mentioned door chain is characterized in that: the periphery of described back-up ring is provided with the vertically extending pad of a circle.
Above-mentioned door chain is characterized in that: this holder and Connection Block are the hollow and thin-walled body.
Advantage of the present utility model is as follows:
1, has only the application of force that connector is pressed to Connection Block,, the head of T shape scarf joint is inserted the inner chamber of Connection Block deeply, just can make its head cross the block of Connection Block inner chamber chute side by back-up ring compression spring.And this pressure can only directly apply, and chain vibrates back and forth, and to beat be to produce this pressure.So the utility model has been eliminated the passive chain hidden danger of taking off that door chain exists up hill and dale.
2, spring closely links connector with Connection Block, and it is moved in chute reposefully, increases the service life.
3, change holder and Connection Block into the hollow and thin-walled part, both weight reductions, economize on material, and be convenient to make, reduce cost.

The specific embodiment:
See also shown in Figure 1ly, the utility model includes holder 3, chain 8, connector 10 and Connection Block 16.Holder 3 is hollow and thin-walled bodies, is respectively arranged with screw hole 5 and connecting hole 2 on its antetheca.These holder 3 mat hold-down screws 6 are arranged in screw hole 5 and are fixed on the doorframe.One end of chain 8 is articulated in the U-lag at coupling bar 7 tops with pin 9; And these coupling bar 7 bottoms are articulated on the connecting hole 2 of holder 3 with screw 1.Connector 10 is arranged on the other end of chain 8.This connector 10 comprises connector 11 and T shape scarf joint 14.The other end of chain 8 is hinged in the U-lag of connector 11 with pin 9.Scarf joint 14 is spirally connected with connector 11, is arranged with back-up ring 13 and spring 12 on its thin neck.These spring 12 two ends are resisted against respectively on the corresponding end-faces of connector 11 and back-up ring 13, and back-up ring 13 is pressed to scarf joint 14 enlarged heads.Scarf joint 14 can substitute with screw.Connection Block 16 also is a hollow and thin-walled part, is respectively arranged with screw hole 5 on its end face and has the chute 15 that enters hole 17.These Connection Block 16 usefulness hold-down screws 6 pass on the relevant position that screw hole 5 is fixed on a back side, and the side that Connection Block 16 inner chambers closely enter hole 17 place's chutes 15 is provided with block 18 (see figure 3)s.During use, the scarf joint aligning of connector 10 is entered hole 17, firmly push connector 11, because back-up ring 13 is resisted against Connection Block 16 surfaces, so spring 12 with connector 11 to Connection Block 16 near compressing, scarf joint 14 enlarged heads that are fixed on the connector 11 enter connector 16 inner chambers, be in until this head below the baseplane of block 18 (as shown in Figure 3), can make it cross block 18 along Connection Block 16 end face translation connectors 10, let go at last, under spring 12 elastic force, connector 11 drives scarf joint 14 and promotes, and is resisted against on Connection Block 16 internal chamber walls until scarf joint 14 enlarged heads, forms assembled state as shown in Figure 2.This moment, connector 10 can slidably reciprocate along chute 15, but hindered by block 18, can not slide to and enter 17 places, hole, unless in addition connector 11 is pressed.For protection spring 12 exempts from damage, the periphery of back-up ring 13 can be provided with the vertically extending pad 19 of a circle.
On holder 2, also can be provided with and comprise the releasing hole 4 that enters hole and chute.When need not be antitheft, connector 10 can be withdrawn from Connection Block 16, embed the chute part (see figure 4)s of removing in the holes 4 and connector 10 inserted, chain 8 all is suspended on the holder 2 like this, does not have any relation with door, a unlatching that no longer hinders.
