Abstract

The utility model relates to a preventing apparatus for abnormal open of a container door, which is for preventing the robbery accident of the container because of the rivet of a linking rack connected to an operating rod is damaged. The lower side of the linking rack is extended with an anti-opening sheet steel which is longer than the moving distance of the left end of a handle. Thereby, even if the rivet of the linking rack is damaged, as the left end of the handle is blocked in the anti-opening sheet steel of the linking rack, the operating rod can not be rotated.

Description

Preventing apparatus for unnermal open of container door

The utility model relates to a kind of unnormal unlocking prevent mean of container door.Even someone to be purpose with the theft destroyed on the linkage frame (that is: the frame that the throw rod on the closing appliance is connected with the handle that has door locking device) connecting piece, but owing to stoped linkage frame to break away from handle, thereby fail to start throw rod still, container door can not be arbitrarily opened, thereby the generation of stolen incident can be prevented.

Usually, the container door of the usefulness that conveys goods or door locking device that the truck doors covered arranged have a throw rod (7) as shown in Figure 1, and it can be rotated motion as S. A. installing under the guiding of the big or small bearing (1) on the chamber door; One or two at throw rod are fixed with shut-off block (11), and it realizes closing with being installed on support component (12) mutual action on the doorframe (2).On above-mentioned throw rod (7), promptly be closed on the position that parts (11) and support component (12) control fully, be welded with linkage frame (4).On this linkage frame, useful rivet (9) bonded assembly, the handle (10) that can rotate.Above-mentioned throw rod is connected with handle, and the door locking device (5) that is set on the chamber door (3) locks.

The formation of above-mentioned door locking device (5) is shown in Fig. 4 A, be welded on linkage frame (8) on the above-mentioned throw rod (7) go up with rivet connecting root morphology complications, with the handle (10) of forging system or cold rolling manufacturing, it can the guard box door closure when closing chamber door fully; One hook (20) is arranged, and its bottom surface is smooth so that firm with the chamber door bolt, and has " Off " shape groove so that hook handle (10) plane, the steel lining that riveted joint is rotated for door lock (13) on the connecting bore of opposite side; One door lock is arranged, and it can guarantee the face full engagement that is connected with handle; This door lock (13) connects or welding by bolt (15).Get up inserting the rivet involution in the involution hole of above-mentioned hook (20), door lock (13), handle (10), thereby make container door keep the involution state.

In order normally to open this container door, open above-mentioned sealing earlier, extract rivet, with door lock (13) to anticlockwise motion, handle (10) is up pushed away a bit, make it to break away from hook (20) back toward anticlockwise, make the shut-off block (11) that is connected on the throw rod (7) break away from support component (12), open container door (3) at last.

Therefore, do not damaging under the rivet sealing device state of above-mentioned container door, be that purpose is when opening container door with the theft, the following way of main employing: shown in Fig. 4 B, destroy the linkage frame (8) of the above-mentioned throw rod of connection and the rivet (9) on the handle (10) earlier, make handle (10) break away from linkage frame (8), spinning movement bar (7) is opened container door then.

The utility model puts forward in order to eliminate above-mentioned prior art shortcoming, its objective is improvement, existing all shortcomings of the original container door of improvement, and the unnormal unlocking prevent mean of container door is provided.

For reaching this purpose, the utility model is that the linkage frame structure of connecting moves bar is simply transformed, thereby even generation is the damage rivet phenomenon of purpose with the theft, still makes the unlikely disengaging linkage frame of handle, still can not the rotational action bar.

Means of the present utility model are, on the linkage frame with rivet connecting moves bar and handle, are extended with anti-unlatching steel disc at the downside of the rivet hole of above-mentioned linkage frame, and the handle left end move distance when it damages than linkage frame rivet is also long.

Like this, be that purpose has been destroyed the connecting piece on the linkage frame with the theft even the people is arranged, but owing to stoped handle and linkage frame to break away from, thereby still can not the spinning movement bar, container door can not be arbitrarily opened, thereby the thievery generation can be prevented.

With reference to the accompanying drawings, further describe the utility model by description to embodiment.

Fig. 1 is the front elevation of container door;

It is the oblique drawing of the container door handle of unnormal unlocking prevent mean that Fig. 2 is to use the utility model;

Fig. 3 is the front elevation of displayed map 2 states;

Fig. 4 A, B and Fig. 2,3 corresponding are respectively the oblique drawing and the front elevation of original technology.

On linkage frame (8) with rivet (9) connecting moves bar (7) and handle (10), downside at the rivet hole (9 ') of above-mentioned linkage frame (8) is extended with the anti-steel disc (29) of opening, and the move distance of handle (10) left end when it damages than linkage frame rivet (9) is also long.

Unnormal unlocking prevent mean according to the utility model design-calculated container door, as shown in Figure 3, even being purpose with the theft, someone destroys rivet (9), with handle (10) to anticlockwise motion, but because the left end of handle (10) will be subjected to the support of the anti-unlatching steel disc (29) of linkage frame (8) downside, so can not rotational action bar (7), also just can't open container door.

Therefore,, need only simply transform, just can reach the generation of prevention thievery the structure of linkage frame if adopt unnormal unlocking prevent mean of the present utility model.

Claims

1, a kind of container door unnormal unlocking prevent mean, on linkage frame (8) with rivet (9) connecting moves bar (7) and handle (10), it is characterized in that, downside at the rivet hole (9 ') of above-mentioned linkage frame (8) is extended with the anti-steel disc (29) of opening, and handle (10) the left end move distance when it damages than linkage frame rivet is also long.
