Abstract

The utility model relates to a hook with a locking structure, comprising a hook and a locking structure. A lock hole in the shape of a step is arranged on the hook (1) adjacent to a hook tip position, and the lock hole is used for placing the locking structure which is composed of a lock draw rod (2), a lock draw cap (8), and a spring (5). The lock draw rod (2) is tightly inserted into the inner hole of the lock draw cap (8), and the lock draw rod (2) and the lock draw cap (8) are connected into an integral body. The spring (5) is sheathed on the lock draw rod (2), and is positioned between the lock draw cap (8) and the hook (1). A position limiting pin (4) is arranged on the lock draw rod (2). The position limiting pin (4) can slide inside the groove opening (3) of a lock hole positioned on one end of a hook back. The hook with a locking structure not only has the advantage of an open type hook, but also is provided with a closed ring body. The hook with a locking structure is safe and reliable.

Description

The hook of fixed structure with lock

The utility model relates to a kind of suspension structures, and relates more specifically to a kind of hook of fixed structure with lock.

In background technique, traditional hook is opening often, though hook or extremely convenient when taking off also very easily causes because of coming off unexpectedly, and produces unsafe factor.The hook that has seals though be provided with reed at the opening of hook, changes to open wide to closed, and is safer, and when hanging or break off relations, all needing to pin reed with hand makes troubles, and in addition if be not intended to run into external force, then may cause the unexpected defective that breaks off relations equally.

Primary and foremost purpose of the present utility model is to design a kind of closed type, and is difficult for because of unexpected factor opening, avoids causing the lockable hook of unhook phenomenon.Another purpose of the present utility model, be to design a kind of locking bar can be limited, thereby form the same lockable of similar open type hook.

The utility model is realized by following design: near the bill place, establish one and be step-like lockhole on hook, with the locking device that is used for settling to draw cap and spring to be formed by lock pull bar, lock.Described lock pull bar and lock draw cap to fuse, and spring then is enclosed within on the lock pull bar, and place lock to draw between cap and the hook.Lock pull bar and lock draw the disjunctor of cap down the effect of spring and lock drawhead spacing, stretch to the bill of hook, and touch mutually with bill and constitute a closed circle, thereby realize sealing and reach safe and reliable purpose.Can be again on the lock pull bar, establish a position limit pin in addition, when pulling lock pull bar and lock draw the disjunctor of cap, and be close to the back of hook, stop lock pull bar and lock to draw the disjunctor of cap by position limit pin,

In a single day effect of the present utility model is clearly, behind the hook that adopts fixed structure with lock described in the utility model, because of the hook sealing, just is difficult for breaking off relations so tangle the back, safe and reliable; Be located at the position limit pin of locking on the pull bar when utilization, then need not to press with hand always, just can make the utility model like the same with the hook that opens wide, hook or unhook are all very comfortable and convenient.In a word, behind employing the utility model, can realize the described expected effect of this specification.

Below in conjunction with accompanying drawing embodiment of the present utility model is described, thereby make CONSTRUCTED SPECIFICATION of the present utility model, characteristics, purpose and advantage clearer and more definite.

Fig. 1 is the utility model embodiment's a structural representation.

Fig. 2 is the structural representation of present embodiment lock pull bar.

Fig. 3 is the structural representation that the present embodiment lock draws cap.

Fig. 4 is the schematic representation of present embodiment opening state.

Among the figure: 1-hook 2-lock pull bar 3-notch 4-position limit pin 5-spring 6-mounting hole 7-mounting hole 8-lock draws cap 9-endoporus 10-guide section.

The utility model embodiment's structure now is described in conjunction with the accompanying drawings:

As shown in Figure 1, present embodiment is described to be a kind of hook that is used for the fixed structure with lock of key-ring, comprise the hook and locking structure form.Be provided with mounting hole 6 and 7 below hook 1, wherein mounting hole 6 generally is used to install link, to hang chain; Mounting hole 7 then is used to encapsulate hanging head, so that hang key-ring on demand.On described hook 1,, then establish one and be step-like lockhole, for settling by the locking structure that comprises that lock pull bar 2, lock draw cap 8, spring 5 to be formed near the bill place.Lock pull bar 2 in the described locking structure is tightly to be plugged in lock to draw in the endoporus 9 of cap 8, and makes lock pull bar 2 and lock draw cap 8 linkage that fuses.Spring 5 then is enclosed within on the lock pull bar 2, and draws between cap 8 and the hook 1 at lock.Spring 5 is made its elastic force force lock pull bar 2 and lock to draw the disjunctor of cap 8 to point to bill, and forms a closed ring body with hook 1 because of linking up with stopping of stepped shaft lockhole step on 1, thereby realizes being difficult for the effect that breaks off relations.When the head of pulling lock pull bar 2, then to lock pull bar 2 and draw the disjunctor of cap 8 in the stepped shaft lockhole, to slide with lock, hook 1 opens wide, can be for linking up with or breaking off relations.Present embodiment can be used for the occasion of various application hooks.

In order to reach the head that need not to hold lock pull bar 2 with hand, can make hook 1 be in opening-wide state, can be in an end place of back at described lockhole, set up a notch 3, on lock pull bar 2, then be provided with position limit pin 4, and can in notch 3, slide.At this moment, the head of pulling lock pull bar 2, position limit pin 4 is slided along notch 3, and after it skids off notch 3, slightly rotate the head of locking pull bar 2, allow position limit pin 4 depart from notch 3, and be subjected to linking up with 1 stop, make lock pull bar 2 and lock draw the disjunctor of cap 8 under the effect of elastic force, not reset, link up with 1 purpose that will be in opening-wide state and realize being scheduled to.

In view of will lock pull bar 2 be inserted in the lock draw in the endoporus 9 of cap 8, in the stepped shaft lockhole, carry out under the sightless state, in order to ensure carrying out smoothly of assembling work, end at described lock pull bar 2, if diameter is less than the guide section 10 of endoporus 9, so that lock pull bar 2 successfully be inserted in the endoporus 9, and a lock pull bar 2 can be drawn cap 8 to join together with lock.
