Abstract

The utility model relates to a lock, particularly a chain lock which discloses a round tube chain lock. A lock core is arranged on one side of a lock body; the other side of the lock body is connected with a chain link of a chain; the middle part of the lock body is provided with a lock head hole; a lock buckle is arranged in the lock body, is fixedly connected with the lock core, and can rotate along with the lock core; the shape of the lock head hole is matched with that of the chain link. Thereby, the utility model has the characteristics that people don't need to design and manufacture a lock head, and the lock can be locked tightly by that the chain link of the chain is directly inserted in the lock body; thus the utility model has the advantages of simple structure and cost saving.

Description

A kind of pipe chain lock

Technical field

The utility model relates to a kind of lockset, especially relates to a kind of chain lock.

Background technology

The common structure of chain lock roughly has lock body, lock core, composition such as tapered end and chain, " Strong chain lock " patent No. if any people's design is 97244871.3, by inner core, overcoat, key, tapered end and chain are formed, the two ends of chain link to each other with inner core and overcoat respectively, the end that inner core has the tapered end perforation is inserted in the corresponding jack of overcoat, and the tapered end perforation is in the interior tapered end jack middle part of overcoat and concentric with the tapered end jack, the tapered end bottom that the tapered end jack is inserted in perforation through tapered end, pin stretches out in the space in the pin baffle plate outside, and the tapered end boss enters in the outer groove that puts.The utility model design relatively in the past is to exist reasonable in designly, simple in structure, is easy to processing, and safety performance is good, promotional value is arranged, but in this structure, the process of locking is the overcoat that is inserted into lock body by tapered end, requisite these parts of tapered end that need.Same other increased the complexity of structure much about all needing tapered end and lock body matching design and manufacturing in the design of chain lock.

Summary of the invention

The utility model solution prior art is existing all will to design the tapered end that matches with lock body when the design chain lock, baroque technical problem, provide a kind of the needs to design tapered end in addition, and directly be that chain link by chain directly is inserted into the pipe chain lock that lock body just can be locked.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of pipe chain lock, be provided with lock core in one side of lock body, opposite side is connected with the chain link of chain, the middle part of lock body is provided with the tapered end hole, be provided with snap close fixedly connected with lock core and that can rotate with lock core in lock body, the shape of described tapered end hole and chain link is complementary.

As preferably, described snap close be shaped as the circular of one section opening, the position of opening is located near near the tapered end hole, the middle part of annulus is connected with lock core.

As preferably, the middle part of the annulus of described circular snap close is fixed on the groove of lock core by stator.

Described tapered end hole be shaped as flat flute profile.

Therefore, the utlity model has does not need design and makes tapered end, and the chain link that has by chain directly is inserted into the characteristics that lock body just can be locked, and with regard to simple greatly structure, provides cost savings.

Description of drawings

Fig. 1 is the schematic perspective view of the utility model embodiment 1.

Fig. 2 is inserted into the assembly structure figure of lock body rear catch and lock core for chain link among the embodiment 1.

Fig. 3 is the perspective view of snap close among the embodiment 1.

The specific embodiment

Below by embodiment, and, the technical solution of the utility model is described in further detail in conjunction with the accompanying drawings 1 to accompanying drawing 3.

Embodiment 1, a kind of pipe chain lock, be provided with lock core 5 in one side of lock body 3, the schematic diagram of lock core 5 has only drawn in accompanying drawing 2, promptly only replace with a rectangle, opposite side is connected with the chain link 1 of chain, the middle part of lock body 3 is provided with tapered end hole 8, described tapered end hole 8 be shaped as flat flute profile, be complementary with the shape of chain link 1, be exactly that chain link 1 can just be inserted in the tapered end hole 8, in lock body 3, be provided with snap close 2 fixedly connected with lock core 5 and that can rotate with lock core 5, circular (referring to the accompanying drawing 3) that be shaped as one section opening of described snap close 2, the position of opening is located near near the tapered end hole 8, and the middle part of annulus is welded with stator 7, also is provided with an installing rack 9 that groove is arranged in stator 7 other sides, stator and installing rack also are welded to connect, installing rack 9 is enclosed within on the lock core 2, also is provided with snap ring 6 simultaneously on lock core 2, installing rack 9 landings that prevent are got off.

When needing the lock article, chain link 1 is inserted in the tapered end hole, by screw key 4, allows chain link 1 enter in the lock body 3, screw key 4 again, drive lock core 5 and snap close synchronously, and snap close just can be locked in connection in the lock body after having rotated certain angle.
