The utility model content

Technical problem to be solved in the utility model provides a kind of angle lock construction of accurate positioning, can be stable as required be in locking or unlocking condition.

In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is:

A kind of freight container orientation angle lock construction is provided, it comprises lock body, lock core, the handle that is connected with this lock core and can make described lock core be stabilized in the retainer spring of locking or lockset position of coupler, described lock core is rotating to be located in this lock body, and have locking between this lock core and the lock body and two cooperation positions of unblanking, this retainer spring is connected with described handle.

Adopt after such structure, because retainer spring can make lock core be stabilized in locking or lockset position of coupler by its elastic force, this just can realize accurately that pinning is fixed and unblanked to standard container.Compared with prior art, effectively avoided the lock core crossover position that mediates, prevented that also the angle lock changes the position because of vibrations in the vehicle operating process, reduced that case falls or box hour angle lock is not unblanked and pull up the danger of trailer.

This angle lock construction preferably resolves freight container traffic special vehicle angle lock position, can effectively avoid in the operational process angle lock to depart from lock position because of vibrations, can open up the good commercial pattern, has certain economic benefits.

Description of drawings

Fig. 1 is the structural representation of the preferred embodiment that provides of the utility model;

Fig. 2 is the working state schematic representation of the preferred embodiment that provides of the utility model, and wherein, Fig. 2 A is the unlocking condition scheme drawing, and Fig. 2 B is the lockup state scheme drawing.

The specific embodiment

In order to make technical problem to be solved in the utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

One preferred embodiment of this angle lock construction shown in Fig. 1 to 2, it comprises lock core 3, lock body 4 and retainer spring 2, described lock core 3 rotating being located in this lock body 4, and have locking between this lock core 3 and the lock body 4 and unblank two cooperation positions, one handle 1 is set on lock core 3, can drives lock core 3 rotations by turning handle and make the angle lock be in locking or unlocking condition.Described retainer spring 2 one ends are connected with this handle 1, the other end then can with wait to load on the frame vehicle of freight container, and can make described lock core 3 be stabilized in locking or lockset position of coupler.

Further, a salient 11 can also be set on described handle 1, the end with described retainer spring 2 is connected with the salient 11 of this handle 1 again; This retainer spring 2 should select to have the retainer spring 2 of suitable pulling force as required.

Because retainer spring 2 can make lock core 3 be stabilized in locking or lockset position of coupler by its elastic force, this just can realize accurately that pinning is fixed and unblanked to standard container.Compared with prior art, effectively avoided lock core 3 crossover position that mediates, prevented that also the angle lock changes the position because of vibrations in the vehicle operating process, reduced that case falls or box hour angle lock is not unblanked and pull up the danger of trailer.This angle lock construction preferably resolves freight container traffic special vehicle angle lock position, can effectively avoid in the operational process angle lock to depart from lock position because of vibrations, can open up the good commercial pattern, has certain economic benefits.

As a preferred specific embodiment, the lock piece that in described lock body 4, also is provided with the locking spring and can be promoted by this locking spring, described lock core 3 is provided with the groove that is complementary with described lock piece.Like this, when described spring promotion lock piece entered in this groove, described lock core 3 was in lockup state with lock body 4; When lock piece left groove, described lock core 3 was in lockup state with lock body 4.Further, described lock piece is preferentially selected steel ball for use; Described groove can be provided with four, is evenly distributed on the circumference in described lock core 3 cross sections, and corresponding, described lock piece and locking spring also have four, can further improve the locating effect between lock core 3 lock bodies 4 like this.
