[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Example 1, as Figures 1-4 As shown, a detachable chair includes a frame 4 and a seat 1. The seat 1 is located on the upper side of the frame 4. The lower part of the frame 4 is provided with four movable gravity wheels 3. The upper side of the frame 4 is provided with an adjustment device 2 for adjusting the height of the seat 1. The adjustment device 2 is provided with two support rods 8 for supporting the seat 1. Each of the two support rods 8 is provided with a fixing mechanism 7. The lower part of the seat 1 is provided with two rectangular plates 6. The two fixing mechanisms 7 fix the seat 1 through the two rectangular plates 6.

[0024] Furthermore, two circular holes are provided on the opposite sides of the two rectangular plates 6;

[0025] Furthermore, the adjustment device 2 includes two telescopic mechanisms 21, which are mounted on the upper part of the fixed frame 4. The two telescopic mechanisms 21 are provided with two crossbars 22 at their close proximity, and the two crossbars 22 are provided with an electric telescopic cylinder 23 for driving on their opposite sides.

[0026] Furthermore, the telescopic mechanism 21 includes two connecting blocks 1 211 and 215. The two connecting blocks 1 211 and 215 are respectively arranged on the opposite sides of the fixed frame 4 and the support rod 8, and the two connecting blocks 1 211 and 215 are staggered. The connecting blocks 1 211 and 215 at the front are both provided with guide rods 214. The two connecting blocks 1 211 are provided with a rotating rod 1 212, and the two connecting blocks 215 are provided with a rotating rod 213.

[0027] Furthermore, rotating rod 1 212 and rotating rod 213 on the same side are connected together, and two guide rods 214 on the same side are connected to the fixed frame 4 and the support rod 8 respectively. The crossbar 22 at the front is set between the two connecting blocks 1 211 at the top, and the crossbar 22 at the rear is set at the bottom of the two support rods 8.

[0028] This device is powered by an external power source.

[0029] Before implementing this device, firstly:

[0030] The movement can be controlled by the electric telescopic cylinder 23, which shortens its output end. The electric telescopic cylinder 23 pulls the horizontal bar 22 connected to its output end backward. At this time, the horizontal bar 22 pulls the two connecting blocks 211 located at the top to slide on the guide rod 214, causing the connecting blocks 211 to move backward along with the front horizontal bar 22. The rotating rod 212, through its rotatable connection with the upper and lower connecting blocks 211, drives the rotating rod 212 as the upper connecting block 211 moves backward. The rotating rod 212 is rotated to a vertical position. When the rotating rod 212 rotates, it is rotatably connected to the rotating rod 213, which will cause the rotating rod 213 to rotate together in the two connecting blocks 215. This causes the rotating rod 212 and the rotating rod 213 to push the support rod 8 upward, thereby adjusting the height of the seat 1. When the height of the seat 1 reaches the required height, the operator closes the electric telescopic cylinder 23, stopping its movement and fixing the seat 1 at the adjusted height.

[0031] In the above, the gravity wheel 3 is a new type of moving component that combines gravity sensing technology with a swivel wheel structure. It mainly controls the wheel's steering, locking, or movement mode by sensing changes in the gravity (or pressure) applied to the wheel, thereby achieving more convenient and precise control of object movement.

[0032] In the above, when the device needs to be disassembled, the staff only needs to pull the two fixing mechanisms 7 to both sides to release the fixing mechanisms 7 from the rectangular plate 6, and then the seat 1 can be removed from the support rod 8. The disassembly method is simple and quick.

[0033] In the above, after the seat 1 is disassembled, the staff can control the output end of the electric telescopic cylinder 23 to move, so that the output end of the electric telescopic cylinder 23 is extended, driving the crossbar 22 to move forward, thereby enabling the rotating rod 1 212 and rotating rod 213 to rotate in a horizontal state, shortening the distance between the fixed frame 4 and the support rod 8, reducing the space occupied by the gravity wheel 3 and the support rod 8, and making the device easy to transport and store.

[0034] In a further embodiment, to achieve the purpose of removing the seat 1 from the support rod 8 via the fixing mechanism 7, see the following... Figure 5 The fixing mechanism 7 includes an arc-shaped plate 72, which is located on a part of the support rod 8 away from the rectangular plate 6. Two locking rods 73 passing through the support rod 8 are provided on the side of the arc-shaped plate 72 near the support rod 8. A pull rod 71 is provided on the side of the arc-shaped plate 72 away from the support rod 8. A sliding rod 75 extending into the support rod 8 is provided on the side of the arc-shaped plate 72 near the support rod 8. A telescopic spring 74 is sleeved on the outer surface of the sliding rod 75.

[0035] Furthermore, the two latches 73 located on one side engage with the circular holes of the rectangular plate 6 on the same side.

[0036] In the above process, when it is necessary to remove the seat 1 from the support rod 8, the staff only needs to pull the lever 71, so that the lever 71 drives the locking lever 73 to slide inside the support rod 8 through the arc plate 72. When the arc plate 72 moves, the locking lever 73 slides out of the circular hole in the rectangular plate 6, canceling the locking of the rectangular plate 6. Then the staff can remove the seat 1 from the support rod 8.

[0037] In the above process, when the seat 1 needs to be placed back on the support rod 8 and the fixing mechanism 7 needs to fix the seat 1, the pull rod 71 needs to be pulled first. The pull rod 71 drives the locking rod 73 to move. When the arc plate 72 moves, it will drive the sliding rod 75 to slide together. At this time, the sliding rod 75 will compress the telescopic spring 74 to generate pressure. Then, the staff will place the seat 1 and the rectangular plate 6 on the support rod 8. Then, the staff will release the pull rod 71. At this time, the telescopic spring 74 will release the pressure and push the sliding rod 75 to move closer to the center. The sliding rod 75 drives the locking rod 73 to move together through the arc plate 72, so that the locking rod 73 can be inserted into the circular hole opened on the rectangular plate 6, thus fixing the seat 1 on the support rod 8.

[0038] It should be noted that the specific installation method, circuit connection method and control method of the electric telescopic cylinder 23 used in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
