[0002] The container VPSA (pressure swing adsorption) device is a device for separating and purifying gases, and is commonly used in industrial production. When the device needs to be moved to a different location or delivered to a customer, a forklift is often used to complete this task. Specifically, first insert the forklift into the fork slot at the bottom of the container, lift the device, and ensure that it is firmly fixed on the forklift, then move the container VPSA device to the truck and secure it by using a safety belt and rope. However, after the existing container VPSA (pressure swing adsorption) device is transferred to the truck, the bottom of the existing container VPSA (pressure swing adsorption) device is in contact with the flatbed of the truck over a large area, and the container VPSA (pressure swing adsorption) device has a certain weight. In order to adjust the position of the container VPSA (pressure swing adsorption) device on the truck, it is carried out by a forklift during the transfer process, and the forklift has limited directions for adjusting the container VPSA (pressure swing adsorption) device, which is not convenient to use.

[0015] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0016] The utility model provides a compact portable container VPSA device, comprising a box body 1, and an oxygen production device 2 arranged inside the box body 1, a socket 101 is arranged on the side of the lower part of the box body 1, at least two groups of damping rods 3 are distributed on the bottom plate of the box body 1, and a locking roller 4 is fixedly connected to the end of the damping rod 3, and a long strip 5 is arranged at the connection between the locking roller 4 and the damping rod 3, and the long strip 5 extends along the length direction of the box body 1 to connect with the damping rod 3 at the other end, and a distance is arranged between the long strip 5 and the bottom plate. The container VPSA device cooperates with a forklift and a truck to realize movement, and the fork arm of the forklift is inserted into the socket 101 and is located between the long strip 5 and the bottom plate. In the initial state, the distance between the long strip 5 and the socket 101 is less than the thickness of the fork arm, and is then restricted by the upper surface of the socket 101. As the fork arm is extended, the lower surface of the fork arm fits the long strip 5 and pushes the long strip 5 down at the same time, and then the long strip 5 is lowered to pull the damping rod 3, and the locking roller 4 is lowered and protrudes from the bottom of the box body 1. When the forklift lifts the box 1, when the forklift places the box 1 on the flatbed behind the truck, the box 1 is pushed, and then the box 1 can be moved on the flatbed through the locking roller 4 to adjust the placement of the box 1. The locking roller 4 has a locking device. When the box 1 moves to the predetermined position, the locking roller 4 is locked, the forklift moves out, and the box 1 automatically and slowly sinks under the coordinated action of the damping rod 3. The damping rod 3 can be selected as model: HTMD-1083, and the damping coefficient is selected or customized according to the load capacity of the box 1. In addition, when the box 1 needs to be fixed in a specific position for use, the locking roller 4 is retracted into the box 1, and then the bottom of the box 1 is in direct contact with the ground, which can ensure that the box 1 is stably placed.

[0017] The two ends of the damping rod 3 are respectively fixedly connected to the bottom of the box 1 and the long strip 5, and the two ends of the damping rod 3 are provided with locking blocks 6. The damping rod 3 is sleeved with a telescopic spring 7, and the two ends of the telescopic spring 7 are fixedly connected to the locking blocks 6. The oxygen generator 2 is placed inside the box 1, and the overall mass is relatively large. According to the sinking speed of the box 1 after the transfer, the stiffness of the appropriate telescopic spring 7 and the damping coefficient of the damping rod 3 are selected, so that when the box 1 sinks, the box 1 compresses the telescopic spring 7, and the compression force of the telescopic spring 7 is partially converted into the supporting force for the box 1, and the supporting force provided by the telescopic spring 7 is less than the damping force of the damping rod 3, so that the damping rod 3 provides a damping effect, and the two work together to make the box 1 sink slowly.

[0018] The long strip 5 is embedded with multiple groups of balls 8 along the length direction. The balls 8 protrude from the upper surface of the long strip 5. When the fork arm of the forklift is inserted into the insertion hole 101, the lower surface of the fork arm is always in contact with the balls 8, which reduces the friction resistance between the fork arm and the long strip 5 when the fork arm is inserted and when the box body 1 is adjusted on the flatbed truck. The locking roller 4 preferably adopts a universal wheel with a universal function. The insertion hole 101 is long and the length is greater than the width of the fork arm. The fork arm is located in the same insertion hole 101, so as to facilitate the multi-directional displacement of the box body 1.

[0019] The width of the forklift's fork arm determines the maximum width of the container that can be accommodated. If the width of the container exceeds the width of the forklift's fork arm, the forklift will not be able to load it onto the truck. The bottom of the box body 1 is provided with a double layer, and the socket 101 is bent inward to form a contact plate 9, and a predetermined distance is provided between the contact plate 9 and the long strip 5. The damping rod 3 is located in the middle of the box body 1 and close to the edge of the box body 1. The top of the damping rod 3 is fixedly connected to the contact plate 9.

[0020] The contact plates 9 extend horizontally from the box 1 to the inside, and the fork arm is inserted from one end of the jack 101 to contact the contact plate 9 at the other end. The ends of the two contact plates 9 are provided with a certain spacing, which reduces the contact area relative to the contact with the bottom plate of the box 1, and can ensure that the forklift can stably lift the box 1. The damping rod 3 is combined with the locking roller 4, and there are four groups, which are evenly distributed at the bottom edge of the box 1. The locking roller 4 is in contact with the ground to ensure the stability of the box 1.

[0021] Working principle: The forklift aligns the fork arm with the socket 101, and gradually extends the fork arm into the contact plate 9. The lower surface of the fork arm gradually pushes the long plate 5 down until the locking roller 4 drops and contacts the ground, and the fork arm is fully inserted. The forklift is driven to move the box 1 to the top of the truck, and the locking roller 4 contacts the flatbed truck. When the position of the box needs to be adjusted, the box 1 can be directly pushed to move, and the locking roller 4 is convenient for adjusting the position of the box 1. The locking roller 4 is locked, and the forklift drives the fork arm to gradually disengage from the socket 101, and the locking roller 4 gradually retracts into the bottom of the box 1. When the fork arm is completely disengaged, the locking roller 4 is located inside the box 1, and the box 1 slowly descends under the action of the damping rod 3, and finally falls on the flatbed truck.

[0022] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be interpreted as limiting the present invention itself. Various changes can be made to it in form and detail without departing from the spirit and scope of the present invention defined in the appended claims.
