Description

A kind of locker

Technical field

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

Background technology

The patent No. is 200610051803 to disclose a kind of typhoon protection freight container rapid locking device, 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, the 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

The problem that exists for solving prior art 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 are flexibly connected, and upper hook or lower hook can move up and down, and the movable upper end with the upper hook junction on lower hook is provided 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 section, and described lateral pin section and axle cross cap are connected together, and lateral pin section is rotated centered by axle and moves.

Optionally, described upper hook is comprised of hook portion and ring portion, and described lower hook is comprised 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 easily processing of each parts;

Lightweight, 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 again one-handed performance 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 a further understanding of the present invention, consists of the application's a part, does not consist of to improper restriction 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 the present embodiment provides, comprise upper hook 1, lower hook 2, upper hook 1 is used for hooking the lower corner fittings of upper strata empty van, lower hook 2 is used for hooking the upper corner fittings of lower floor's empty van, upper hook 1 and lower hook 2 are flexibly connected, so that upper hook and lower hook are convenient when inserting corner fittings, in the present embodiment, upper hook 1 is comprised of hook portion 101 and ring portion 102, lower hook 2 is comprised 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;

Movable upper end with the upper hook junction on lower hook 2 is provided with swivel pin 4, and swivel pin 4 is rotatable and mobile.When needing locking, rotate swivel pin 4, so that swivel pin intersects with upper hook, lower hook namely can't be movable like this, realizes the purpose of locking; When needing release, rotate swivel pin, make swivel pin 4 vertical, until do not hinder 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 such as the mode in the present embodiment, staight shank 202 parts that swivel pin 4 are connected to lower hook 2 by axle 3 in the present embodiment, swivel pin 4 comprises mobile division 401 and lateral pin section 402, lateral pin section 402 is connected together with axle 3 cross caps, lateral pin section 402 is rotated and moves centered by axle 3, 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 irremovable.

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

First 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 upper hook 1 the lower corner fittings of upper strata empty van, lower hook is hooked the upper corner fittings of lower floor's empty van;

When swivel pin 4 rotates swivel pin from the ring portion 102 of upper hook after out, make the swivel pin oblique cutting on the ring portion of upper hook, upper hook 1 and lower hook 2 are irremovable, and lower hook and upper hook form and surround, pin the up and down corner fittings of two freight containers, so that top freight container can not move outward.

For so that swivel pin more securely with the locking of upper hook and lower hook, and for so that the rotation of swivel pin 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 like this inclined-plane has one along oblique prone power, the locking that guarantees it is more firm, and swivel pin rotates flexibly.

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