In order to solve the problem that exists among the prior art, the utility model provides a packing box is to opening chamber door locking device can supply many parties to use simultaneously and unblank.

Take the field of express delivery transportation as an example. In the field of express delivery transportation, as express delivery is ensured not to be lost in the transportation process, the express delivery box needs to be locked and transported; the requirement that multiple parts of the same equipment can be locked simultaneously needs to be met due to the transportation requirements among different express points in the same region or among different express points in different regions, and the requirements of simplicity and convenience in operation, low price and good environment applicability are met.

The structure and the application method of the container side-by-side door locking device according to the embodiment of the present invention will be described with reference to the accompanying drawings.

Fig. 1 is a schematic structural view of a container side-by-side door locking device according to an embodiment of the present invention. As shown in fig. 1, the container door locking device for a container that can be used in multiple directions at the same time of the present invention mainly includes a latch structure 1, a rotary table 2, a first latch 11 and a second latch 12. The bolt structure 1 comprises a bolt rod 13 and a limiting block 14; the rotary disc 2 is provided with a pin hole 3 for inserting or removing the latch rod 13. The first pin bolt 11 is arranged on the first box door, the second pin bolt 12, the bolt structure 1 and the turntable 2 are sequentially arranged on the second box door, and the first pin bolt 11, the second pin bolt 12, the bolt structure 1 and the turntable 2 are arranged at the same horizontal height; the limit block 14 is fixed on the latch rod 13 and arranged between the second latch 12 and the rotary disc 2 for limiting the locking device in the open or locked state.

According to another embodiment of the present invention, the turntable 2 can be fixed by the rotating shaft 4 and can rotate around the rotating shaft 4. The rotating shaft 4 is, for example, a nut structure or a rivet structure.

According to the technical scheme of the utility model, the bolt structure can be arbitrary form, and first cotter 11 and second cotter 12 can be one or more. For example: there are 2 first pegs 11 and 2 second pegs 12, or there are 1 first peg 11 and 2 second pegs 12, and so on. The lengths of the first pin 11 and the second pin 12 may be flexibly set as needed. Additionally, the utility model discloses in do not specifically prescribe a limit to the form of tool to lock yet, all have the structure or the device of tool to lock function all can be used to realize the technical scheme of the utility model.

Fig. 2 is a schematic structural diagram of the turntable and the pin holes according to an embodiment of the present invention. As shown in fig. 2, a plurality of pin holes 3 are formed on the side surface of the turntable 2 and are spaced apart from each other on the turntable 2. Each pin hole 3 can be provided with a lock, and the pin hole 3 is sized to receive a latch rod 13. The number of the pin holes 3 can be set according to actual needs. If a plurality of persons need to use the container door locking device for opening the container door in two directions, a plurality of pin holes 3 need to be formed in the side face of the rotary table 2, and at the moment, the rotary table 2 needs to be larger so as to facilitate hole opening and locking. In a specific embodiment of the present invention, the number of the pin holes 3 may be two or three, for example.

When specifically using, need earlier with the utility model discloses a packing box is opened chamber door locking device and is installed. Taking the installation on the cargo container door which is opened in two directions as an example, when the installation is carried out, the first bolt 11 is installed on the first container door, the second bolt 12, the bolt rod 13, the limiting block 14, the rotary table 2 and the like are all installed on the second container door, and the first bolt 11, the second bolt 12, the bolt rod 13, the limiting block 14 and the rotary table 2 are arranged at the same horizontal height.

The method of using the locking device for the box side-by-side opening door of the present invention will be described with reference to fig. 3 and 4.

Fig. 3 is a schematic structural diagram of an open state of the locking device according to an embodiment of the present invention, in which the lock is not shown. When a lock is opened, the corresponding pin hole 3 of the lock is free, the rotating disc 2 is rotated to align the free pin hole 3 with the latch rod 13, then the latch rod 13 is moved and inserted into the free pin hole 3 until the latch rod 13 is completely separated from the first latch 11, and the latch rod 13 is inserted into the second latch 12 and the free pin hole 3, so that the box door locking device is in an open state.

Fig. 4 is a schematic structural diagram of a closed state of the locking device according to an embodiment of the present invention, in which the lock is not shown. As shown in fig. 4, when it is required to close the door locking device of the container side-by-side opening door, first, the latch rod 13 is removed from the pin hole 3 until it is inserted into the first latch 11, at which time, the latch rod 13 is completely separated from the pin hole 3 and inserted into the first latch 11 and the second latch 12 so that the door locking device of the container side-by-side opening door is in a closed state. It will be appreciated by those skilled in the art that when the container side-by-side door locking mechanism is in the closed position, a lock is located in each of the pin holes 3, the latch rod 13 is completely separate from the pin holes 3 and the latch rod 13 must be inserted into the first pin 11 to secure the locking mechanism in the closed position. Under the closing state of the container door locking device, a certain gap is formed between the rotary table 2 and the bolt rod 13, the rotary table 2 can still rotate, but due to the limiting effect of the limiting block 14, the gap is not enough to enable the bolt rod 13 to be completely separated from the first bolt 11, and therefore the container door locking device is ensured to be in the closing state.

In the actual use process, locks are arranged at the pin holes 3 of the rotary disc 2 in advance in multiple parts needing to be locked at the same time, any user uses a key to unlock the own installed lock, the rotary disc 2 is rotated after the locks are taken down, when the pin holes 3 on the rotary disc 2 are aligned with the bolt rods 13, the bolt rods 13 are moved, the bolt rods 13 are inserted into the pin holes 3 and completely withdrawn from the first pin holes 11, and therefore the container box door locking device is unlocked; the container door locking device can be closed by reversely executing the operation process.

According to the utility model discloses technical scheme combines together bolt structure, first cotter and second cotter and the carousel that has the pinhole to install the tool to lock in the pinhole, open locking device through removing bolt pole to pinhole in, and shift out from the pinhole through the bolt pole and close locking device, make this locking device can satisfy the demand of locking simultaneously in many ways, and easy and simple to handle, with low costs, environmental suitability is strong.

It will be appreciated by those skilled in the art that the locking device of the present invention needs to be installed on both sides of the device to be locked. The equipment of waiting to lock refers to the equipment that needs to lock, installs on it the utility model discloses a locking device, wait to lock equipment for example but not limited to: the doors of a freight container, or the doors of a container car, or optionally a door, etc. The locking device can be arranged on both sides of the double door, or on the single door and the corresponding door frame, etc.

The above detailed description does not limit the scope of the present invention. Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions can occur, depending on design requirements and other factors. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
