Description

A kind of novel hook-type lock with locking anti-drop function

Technical field:

The utility model relates to a kind of novel hook-type locks with locking anti-drop function.

Background technique:

It is by hook component and to hook coil component and constitute that hook-type on the market, which latches most popular structure, at present, and when hook joint relies on Hook component therein catches on coil component and realizes hook joint, and the traditional structure of this hook-type lock is the folded over of hook component Hook segment is all linear state, and when this linear folded over hook segment catches on coil component, hook joint is very easy to, but can equally be existed One serious problem, the folded over hook segment of hook component, which can be very easy to be detached from, hooks coil component, causes hook joint to fail, and this Unhook happens that probability is very big, causes the connection of two connecting components unreliable.

Utility model content:

The shortcomings that the purpose of this utility model is to overcome the above-mentioned prior arts provides a kind of with locking anti-drop function Hook-type lock.

The goal of the invention of the utility model can be realized by technical solution below: one kind having locking anti-drop function Novel hook-type lock, include hook component and hook coil component, the gib head of hook component forms by two wires parallel winded, And converge in the folded over hook segment end of hook component, the folded over hook segment two wires of hook component are all protruded to two sides bending respectively There is flaring, while being bent with clamp towards hook component main direction in the middle part of the two wires of folded over hook segment, hook component is caught on Coil component hooks coil component wire rod and sticks into the space between the clamp of hook component and folded over hook segment bottom end.

The rear end of hook article body and the rear end for hooking coil component all form clamping ring.

After the technical program, compared with prior art, the technical program is had the advantage that by utilizing folded over hook Towards the molding card of hook component main bent part in the middle part of the flaring and the folded over hook segment that section two wires are protruded to two sides design Head under the dual buckle status of two kinds of latching structures, ensure that hook component highly reliably live to hook coil component by hook lock, reaches two It will not generate and loosen between component, guarantee reliably to combine between component.

Detailed description of the invention:

Fig. 1 is the separated structure figure of the utility model hook-type lock；

Fig. 2 is the fastening structure figure of the utility model hook-type lock；

Fig. 3 is the fastening sectional structure chart of the utility model hook-type lock；

Fig. 4 is the decomposition sectional structure chart of the utility model hook-type lock.

Specific embodiment:

This technology is described further with reference to the accompanying drawing.

The hook-type lock of the present embodiment includes hook component 1 and hooks coil component 2, and the gib head 11 of hook component 1 is by two Wire rod parallel winded forms, and converges in 111 end of folded over hook segment of hook component 1, the folded over hook segment 111 of hook component 1 Two wires are all protruding with flaring 112, width of the distance between the two sides flaring 112 than hooking coil component 2 to two sides bending respectively More greatly, while clamp 13, clamp 13 are bent with towards 12 direction of hook article body in the middle part of the two wires of folded over hook segment 111 The distance between hook article body 12 is more a little bit smaller than the coil diameter for hooking coil component 2, and hook component 1 catches on coil component 2, It hooks 2 wire rod of coil component to stick into the space 14 between 111 bottom end of clamp 11 and folded over hook segment of hook component 1, hook component master The rear end of body 12 and the rear end for hooking coil component 2 all form clamping ring 3, and the effect of clamping ring 3 is responsible for appendix and is needing to connect Components interior, make hook component 1 and hook coil component 2 be mounted on component.

When hook joint, flaring 112 and clamp 13 in the folded over hook segment 111 of hook component 1 can be forced by hook coil component 2 to be become Shape, finally makes 111 overall deformation of folded over hook segment of hook component 1 and immediately elasticity affranchises state across hooking after coil component 2, To reach prevent from hook component 1 and hook after coil component 2 is locked that disengaging problem occurs.When needing to free, as long as artificially bestowing Certain thrust, the resistance for overcoming flaring 112 and clamp 13 to deform, so that it may so that the folded over hook segment 111 of latch part 1 becomes again Shape, and finally make hook component 1 and hook the disengaging unlock of coil component 2, solve the problems, such as all existing unhook of traditional hook-type lock.

The above descriptions are merely preferred embodiments of the present invention, not makees in any form to the utility model Limitation.Anyone skilled in the art, it is all available in the case where not departing from technical solutions of the utility model ambit The methods and technical content of the disclosure above makes many possible changes and modifications to technical solutions of the utility model, or is revised as The equivalent embodiment of equivalent variations.Therefore all contents without departing from technical solutions of the utility model, the shape according to the utility model Equivalence changes made by shape, construction and principle should all be covered by the protection scope of the utility model.
