Description

A kind of locker

Technical field

The present invention relates to a kind of locker, especially a kind of locker that is used for the freight container typhoon protection.

Background technology

The patent No. is 200610051803 to disclose the quick locker of a kind of typhoon protection freight container, by top collude, with the bottom of tooth bar collude, 18 parts such as gear, ratchet, little axle, locking pin, fork handle, plastic handles, spring, spring cotter form, its middle gear, ratchet, little axle, locking pin all need fine limit work, defectives such as complex structure, part are many so the freight container typhoon protection locker of prior art exists, Heavy Weight, the operation of inconvenient operating personal.

Summary of the invention

For solving the problem that prior art exists, the invention provides a kind of simple in structure, easy to operate locker.

The present invention is achieved in that

A kind of locker comprises upper hook, lower hook, and described upper hook and lower hook flexibly connect, and upper hook or lower hook can move up and down, and the upper end with the upper hook junction on lower hook is movably set with swivel pin, and swivel pin is rotatable and mobile.

Optionally, described swivel pin is connected on the lower hook by axle, and described axle is fixedly connected on the lower hook, and described swivel pin comprises mobile division and lateral pin portion, and a described lateral pin portion and an axle cross cap are connected together, and lateral pin portion is that the center is rotated and moves with the axle.

Optionally, described upper hook is made up of hook portion and ring portion, and described lower hook is made up of hook portion and staight shank two parts, and described staight shank partly penetrates the ring portion of upper hook, and can move up and down in the ring portion of upper hook.

Optionally, the ring portion upper surface of upper hook is an inclined-plane.

Locker provided by the invention has the following advantages:

Simple in structure, parts are few, and locker and the also processing easily of each parts;

In light weight, existing freight container typhoon protection locker deadweight has 2kg, and locker deadweight provided by the invention is about 1.1kg;

Simple to operate, step is few, respectively upper hook and lower hook is inserted in the hole of container angle, mentions lower hook by swivel pin, rotates swivel pin and itself and upper hook upper surface are intersected and is shelved on the upper hook upper surface, just can realize the purpose of locking;

Safety is because locker makes things convenient for one-handed performance again from heavy and light, so operator's another hand can be used for the safety guard-safeguard of self.

Description of drawings

Accompanying drawing described herein is used to provide further understanding of the present invention, constitutes the application's a part, does not constitute to improper qualification of the present invention, in the accompanying drawings:

The structural representation of the locker that Fig. 1 provides for the embodiment of the invention;

Fig. 2 is the structural representation of another angle of locker.

The specific embodiment

Describe the present invention in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the present invention in this illustrative examples of the present invention and explanation, but not as a limitation of the invention.

As shown in Figure 1, 2, the typhoon protection locker that is used for freight container that present embodiment provides, comprise upper hook 1, lower hook 2, upper hook 1 is used to hook the following corner fittings of upper strata empty van, lower hook 2 is used to hook the last corner fittings of lower floor's empty van, upper hook 1 and lower hook 2 flexibly connect, it is convenient to make when upper hook and lower hook are inserted corner fittings, in the present embodiment, upper hook 1 is made up of hook portion 101 and ring portion 102, lower hook 2 is made up of hook portion 201 and staight shank 202 two parts, and staight shank part 202 penetrates the ring portion 102 of upper hook, and can move up and down in the ring portion 102 of upper hook;

Upper end with the upper hook junction on lower hook 2 is movably set with swivel pin 4, and swivel pin 4 is rotatable and mobile.When needing locking, rotate swivel pin 4, make swivel pin and upper hook intersect, lower hook promptly can't be movable like this, realizes the purpose of locking; When needing release, rotate swivel pin, make swivel pin 4 vertical, up to not hindering moving up and down of lower hook 2, vertical swivel pin 4 and the staight shank of lower hook part move down in the ring portion of upper hook, can realize the purpose of release.

Wherein, swivel pin 4 has multiple with the movable connection method of lower hook 2, for example swivel pin can adopt concaveconvex structure to be movably arranged on the lower hook, also can be as the mode in the present embodiment, in the present embodiment staight shank 202 parts that swivel pin 4 are connected lower hook 2 by axle 3, swivel pin 4 comprises mobile division 401 and lateral pin portion 402, lateral pin portion 402 is connected together with axle 3 cross caps, lateral pin portion 402 is that the center is rotated and moves with axle 2, when swivel pin 4 turns to vertical state, can not stop moving up and down of upper hook or lower hook, when the upper surface of swivel pin and upper hook 1 intersects, upper hook or lower hook are locked, and be not removable.

The working process of the locker that present embodiment provides is:

Earlier swivel pin 4 is turned to vertical state, this moment swivel pin 4 in staight shank part 202 inside of lower hook, removable upper hook 1 or lower hook 2 are hooked the following corner fittings of upper strata empty van with upper hook 1, lower hook is hooked the last corner fittings of lower floor's empty van;

After coming out from the ring portion 102 of upper hook, swivel pin 4 rotates swivel pin, make the swivel pin oblique cutting on the ring portion of upper hook, upper hook 1 and lower hook 2 are not removable, and lower hook and upper hook form and surround, pin the corner fittings up and down of two freight containers, the freight container above making can not move outward.

In order to make swivel pin more securely with upper hook and lower hook locking, and for make swivel pin rotation more nimbly and freely, ring portion 102 upper surfaces of upper hook can be designed to the inclined-plane in the present embodiment, the swivel pin that is shelved on the inclined-plane like this has a power downward along the inclined-plane, the locking that guarantees it is more firm, and swivel pin rotates flexibly.

More than the technical scheme that the embodiment of the invention provided is described in detail, used specific case herein the principle and the embodiment of the embodiment of the invention are set forth, the explanation of above embodiment only is applicable to the principle that helps to understand the embodiment of the invention; Simultaneously, for one of ordinary skill in the art, according to the embodiment of the invention, the part that on the specific embodiment and field of application, all can change, in sum, this description should not be construed as limitation of the present invention.
