Abstract

The utility model relates to a joint lock which comprises a lock head, a lock tongue which can be locked with the lock head, and a lock chain, wherein, two ends of the lock chain are respectively connected with the lock head and the lock tongue. When the lock head and the lock tongue are locked, the lock head, the lock tongue and the lock chain form a locking closed state. Steel cables in the lock chain are enclosed by a plurality of lock chain sleeve shells which are mutually connected in series. The joint lock has the advantages of mould cost saving, simple structure and low cost. In addition, the lock chain can be freely bent.

Description

Joint lock

The utility model relates to a kind of Joint lock, the improvement of chain structure in especially a kind of Joint lock.

In traditional Joint lock, as Fig. 1, the public chain sheath body that the chain sheath body is protruded out by a plurality of two ends end to end reaches end to end, and the recessed fundamental chain sheath body in two ends alternately is serially connected, the two ends of public chain sheath body 2 have the insertion section 210 of being protruded by outer radial axle center convergent, the two ends of fundamental chain sheath body 1 have by outer radial inner axes convergent to the recessed receiving portion 110 of housing, when the insertion section 210 of public chain sheath body 2 alternately is connected in series with the receiving portion 110 of a plurality of fundamental chain sheath bodies 1, the public affairs of serial connection, fundamental chain sheath body center promptly forms path and passes through by cable wire, it is cable wire 4 enters public chain sheath body 2 by the insertion section 210 of public chain sheath body 2 cavity, enter the insertion section 210 of the other end of public chain sheath body 2 again, receiving portion 110 by the fundamental chain sheath body, enter the cavity of fundamental chain sheath body again, carry out so repeatedly.

Make traditional Joint lock and need make public chain sheath body and two kinds of chain sheath bodies of fundamental chain sheath body respectively, need to make two kinds of moulds, to make public chain sheath body and fundamental chain sheath body respectively so that encase cable wire fully.So just make structure complicated, thereby also increased manufacturing cost.

The purpose of this utility model is to propose a kind of improved Joint lock, and its chain only adopts a kind of chain sheath body, makes designs simplification, and manufacturing cost reduces, and still keeps the free bend character of Joint lock simultaneously.

The utility model is achieved in that a kind of Joint lock, comprise tapered end, dead bolt that can be sealed with tapered end, two ends connect tapered end and dead bolt respectively, when tapered end and dead bolt are sealed and chain form the chain of sealed closed state, it is characterized in that: form chain by cable wire and a plurality of chain sheath body, cable wire in the chain is surrounded by a plurality of continuous chain sheath bodies 3, it is male end that the two ends of described chain sheath body 3 are an end, the other end is the pattern of female end, and to form last chain sheath body be male end insertion section 310, and back one chain sheath body is the chain sheath body connected mode of female end receiving portion 320.Chain sheath body male end is served as reasons outer and interior insertion section 310 of protruding to the axle center convergent, and female end is that ecto-entad is to the axle center convergent and to the receiving portion 320 of housing indent, a plurality of chain sheath bodies agree with serial connection by the male and female end and are enclosed in the cable wire outside together.

The utility model has reduced the mould fabricating cost, and is simple in structure, and manufacturing cost reduces, and still kept the free bend character of Joint lock.

Fig. 1 is the three-dimensional exploded view of public Joint lock.

Fig. 2 is the three-dimensional exploded view of the utility model Joint lock.

Now further narrate structure of the present utility model in conjunction with the accompanying drawings.

Referring to Fig. 2: the utility model comprises tapered end, dead bolt, chain that can be sealed with tapered end.Rising of chain, terminal point links aforesaid tapered end and dead bolt respectively, when tapered end and dead bolt are sealed, form sealed closed state with chain, cable wire in the chain is to surround by single kind of chain sheath body is continuous, and the two ends of each chain sheath body 3 are a public mother pattern, be that male end is served as reasons outer and interior insertion section 310 of protruding to the axle center convergent, female end is served as reasons outer and interior to the axle center convergent and the receiving portion 320 of housing indent, when the male end of continuous plural chain sheath body is agreed with serial connection with female end, promptly forming hollow passage allows cable wire pass through, cable wire two termination tapered end and dead bolts make it form the closed state of sealed sealing and energy free bend.

Claims

1, a kind of Joint lock, comprise tapered end, dead bolt that can be sealed with tapered end, two ends connect tapered end and dead bolt respectively, when tapered end and dead bolt are sealed and chain form the chain of sealed closed state, it is characterized in that: form chain by cable wire and a plurality of chain sheath body, cable wire in the chain is surrounded by a plurality of continuous chain sheath bodies (3), it is male end that the two ends of described chain sheath body (3) are an end, the other end is the pattern of female end, and to form last chain sheath body be male end insertion section (310), and back one chain sheath body is the chain sheath body connected mode of female end receiving portion (320).

2, by the described Joint lock of claim 1, it is characterized in that: chain sheath body male end is served as reasons outer and interior insertion section (310) of protruding to the axle center convergent, female end is that ecto-entad is to the axle center convergent and to the receiving portion (320) of housing indent, a plurality of chain sheath bodies agree with serial connection by the male and female end and are enclosed in the cable wire outside together.
