Description
Technical Field
The utility model relates to a lock theftproof technical field specifically is a novel anti-theft chain.
Background
The existing anti-theft chain is mostly arranged at a place which is not far away from the door edge on the back of a door through a chain buckle, one end of a sliding chain is fixed on a door frame, and the other end of the sliding chain is a movable clamping rod which can be inserted into the chain buckle on the back of the door to be locked. The thief can easily remove the safety lock function of the anti-theft chain by using the characteristic that the clamping rod can freely slide in the sliding groove and using the adhesive tape, the rubber band and the like, so as to steal. In the prior art, solutions such as improving the product quality and adding complex anti-theft programs are mostly adopted for solving the problems, so that the production cost is increased, the production steps are increased, and time and labor are wasted.
Disclosure of Invention
The utility model aims to solve the technical problem that overcome the above-mentioned not enough that exists among the prior art, and provide a structural design reasonable, simple easy-to-use, and can effectual problem that the leak brought more than solving.
The utility model provides a technical scheme that above-mentioned technical problem took is: the novel anti-theft chain comprises a chain buckle and a sliding chain, wherein one end of the sliding chain is fixed on a fixing plate, and the other end of the sliding chain is connected with a clamping rod. The middle part of the clamping rod is a cylindrical connecting rod, one end of the clamping rod is a baffle, and the other end of the clamping rod is a spherical cap. The chain link is a hollow cuboid without a bottom surface, four corners of the upper bottom surface are provided with mounting holes, a limiting hole is formed in the middle of the cuboid, a sliding groove is formed in the sliding groove, and the limiting hole is covered and pressed by the elastic sheet from the inside. The fixed plate is provided with a limiting hole, a sliding groove and a mounting hole.
Compared with the prior art, the utility model, following obvious advantage has: the anti-theft chain has the advantages of reasonable structural design, simplicity, easiness in manufacturing and easiness in use, not only keeps a plurality of advantages of the anti-theft chain, but also strengthens the anti-theft function of the anti-theft chain.

Detailed Description
The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The novel anti-theft chain comprises a chain buckle 1 and a sliding chain 2, wherein one end of the sliding chain 2 is fixed on a fixing plate 4, and the other end of the sliding chain is connected with a clamping rod 3. The middle part of the clamping rod 3 is provided with a cylindrical connecting rod 6, one end of the clamping rod is provided with a baffle 5, and the other end of the clamping rod is provided with a spherical cap 7. The chain buckle 1 is a hollow cuboid without a bottom surface, four corners of the upper bottom surface are provided with mounting holes 11, a limiting hole 8 is arranged in the middle, a sliding groove 9 is formed in the middle, and the limiting hole 8 is covered and pressed by an elastic sheet 10 from the inside. The fixed plate 4 is provided with a limiting hole 12, a sliding groove 13 and a mounting hole 11.
The chain buckle 1 is arranged at a position which is not far away from the door edge behind the door, and the fixing plate 4 at one end of the sliding chain 2 is fixed on the door frame. The rectangular four side surfaces of the chain buckle 1 ensure a certain distance between the upper bottom surface and the door plate, so as to be beneficial to the elastic deformation space of the elastic sheet 10 and the sliding of the clamping rod 3 in the sliding groove 9. The slide chain 2 is composed of a metal chain, and canvas materials are wrapped outside the slide chain. The cooperation of spout 9, spacing hole 8 and kelly 3 has guaranteed that the baffle 5 of kelly 3 can only be put into from spacing hole 8 to the baffle 5 and the spherical cap 7 of kelly 3 can slide and can't deviate from with its restriction in spout 9. The elastic sheet 10 is riveted inside the chain buckle 1 and closely attached to the limiting hole 8, and the riveting point is between the limiting hole 8 and the top mounting hole 11, so that the elastic sheet can be pressed down from the limiting hole 8 to be elastically deformed.
When the door is used, the door is in a closed state, the clamping rod 3 at one end of the slide chain 2 is positioned in the sliding groove 9 on the chain buckle 1, and at the moment, even if the door is opened, a gap of about 4 cm is formed. At this time, the clamping rod 3 is pulled upwards, and the clamping rod 3 slides for a section and can be clamped by the elastic sheet 10 and can not slide to the position of the limiting hole 8 and can not be separated from the sliding groove 9. Therefore, the defect that a thief can steal the door by means of tools such as adhesive tapes, rubber bands and the like through the sliding of the clamping rod 3 in the sliding groove 9 and the separation from the limiting hole 8 is well overcome.
When the clamping device is not used, the clamping rod 3 can be lifted upwards, and the elastic sheet 10 is pressed down through the limiting hole 8 by fingers to be opened for a certain angle, so that the clamping rod 3 can smoothly slide out of the limiting hole 8. Then the clamping rod 3 can be put in from the limiting hole 12 and can slide into the sliding chute 13 to accommodate the clamping rod 3 and the sliding chain 2, thus avoiding the occurrence of free suspension and reciprocating swing of the sliding chain 2 when the anti-theft chain is not used.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
