[0003] The unmanned board game room will monitor and manage the status of the equipment and environmental conditions in the room in real time. For example, the chairs in the unmanned board game room are just ordinary chairs placed in the room. If someone enters the room, they can use them even without paying.

[0004] To address this issue, a chair recycling device has been proposed that can automatically recycle and place chairs, and can only be used after payment is made. Utility Model Content

[0005] The purpose of this invention is to provide an automatic chair retrieval device. This invention can automatically retrieve chairs using a lifting device and a telescopic device, saving labor.

[0006] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0007] To address the technical problems mentioned in the background section above, some embodiments of this application provide an automatic chair recycling device, including:

[0008] support;

[0009] The connecting platform slides up and down on the bracket;

[0010] The lifting assembly is mounted on the support frame and located below the connecting platform;

[0011] The telescopic assembly is located on the connecting platform, around the perimeter of the connecting platform;

[0012] The lifting component is located on the connecting platform;

[0013] The limit assembly, which has multiple units, is mounted on the bracket and located around the connecting platform;

[0014] The telescopic group includes:

[0015] The first driving component is mounted on the bracket;

[0016] The first lead screw is connected to the first driving component;

[0017] The connector is located on the first lead screw and is fixedly connected to the chair.

[0018] The lifting component has a long, narrow lifting section that inserts into the bottom of the chair.

[0019] Furthermore, the connecting component is a horizontal coupling.

[0020] Furthermore, the lifting assembly includes:

[0021] The second driving component is mounted on the bracket and located below the bracket;

[0022] The second lead screw is rotatably mounted on the bracket and is connected to the second drive component for transmission.

[0023] The ball bearing slider is mounted on the second lead screw;

[0024] The ball bearing slider is fixedly connected to the connecting platform.

[0025] Furthermore, bearing blocks are provided at both the upper and lower ends of the second lead screw, which are rotatably connected to the second lead screw; the bearing blocks are fixed on the bracket.

[0026] Furthermore, the limit group includes:

[0027] The upper fixing block is mounted on the bracket;

[0028] The lower fixing block is mounted on the bracket;

[0029] The guide shaft is fixed at both ends to the upper and lower fixing blocks, respectively.

[0037] Compared with the prior art, the present invention has the following beneficial effects:

[0038] 1. The extension mechanism moves the chair closer to the support, allowing it to move above the lifting section. The lifting mechanism is then activated to move the lifting section upwards, retracting the chair. This automated, quick, and convenient chair retraction, combined with a detection system installed in the board game room, ensures that the chair is retracted under the table before payment and is moved out from under the table after payment.

[0039] 2. By using a horizontal coupling as the connecting component, the rotation of the first lead screw is canceled out, so that the first lead screw can only drive the chair to move horizontally without rotating.

[0040] 3. By having the guide slider slide up and down on the guide shaft, the shaking of the connecting platform is reduced, and the stability of the chair is increased when it moves up and down. Attached Figure Description

[0061] Reference Figure 1-4 An automatic chair retrieval device can be installed under a table. The device includes: a support 101, a connecting platform 102, a lifting assembly 103, a telescopic assembly 104, a lifting component 105, and a limiting assembly 106. The connecting platform 102 is slidably mounted on the support 101. The lifting assembly 103 is mounted on the support 101, driving the connecting platform 102 to move up and down. The telescopic assembly 104 is mounted on the connecting platform 102 and located around its perimeter. The lifting component 105 is fixed to the telescopic assembly 104 and has a long, narrow lifting section 105a that is horizontally positioned and inserted under the chair. Multiple limiting assemblies 106 are mounted on the support 101 and located around the connecting platform 102.

[0062] Casters 107 are installed under the chair to reduce friction between the chair and the ground during movement.

[0063] The lifting member 105 also includes a connecting part 105b, which is fixed on the connecting platform 102. The connecting part 105b is vertically arranged and forms an L-shape with the horizontally arranged lifting part 105a.

[0064] When the chair is retrieved, the telescopic assembly 104 is activated, moving the chair above the lifting section 105a. Then, the lifting assembly 103 is activated, moving the connecting platform 102 upward. The connecting platform 102 moves the lifting component 105 upward, lifting the chair and retrieving it. Only after payment is made will the lifting assembly 103 and the telescopic assembly 104 be activated to move the chair out and place it for the user to sit on. If payment is not made, the chair is retracted under the table and the user cannot sit on it.

[0065] The telescopic assembly 104 includes: a first drive member 104a, a first lead screw 104b, and a connector 104c; the first drive member 104a is a through-type stepper motor, fixed on the connecting platform 102; the first lead screw 104b passes through the first drive member 104a, and one end of the first lead screw 104b is connected to the chair through the connector 104c; the connector 104c is a horizontal coupling, fixed on the side wall of the chair, and the connector cancels out the rotation of the first lead screw 104b, so that the rotation of the first lead screw 104b cannot be transferred to the chair, but can only drive the chair to move horizontally.

[0066] After the first drive unit 104a is started, it drives the first lead screw 104b to rotate. The rotation of the first lead screw 104b will drive the chair to move closer to the support 101. When the chair is close to the support 101, the chair will move above the lifting part 105a. Then, in conjunction with the lifting assembly 103, the chair will move up and retract.

[0067] The lifting assembly 103 includes: a second driving member 103a, a second lead screw 103b, a ball bearing slider 103c, and a bearing block 103d; the second driving member 103a is fixed on the bracket 101 and located directly below the bracket 101; the second lead screw 103b is connected to the second driving member 103a so that the second driving member 103a drives the second lead screw 103b to rotate; the ball bearing slider 103c is sleeved on the second lead screw 103b and is fixed on the connecting platform 102; there are two bearing blocks 103d, which are fixed on the bracket 101 and located at the upper and lower ends of the second lead screw 103b, respectively rotatably connected to the upper and lower ends of the second lead screw 103b.

[0068] When the chair is retracted, the first lead screw 104b rotates, causing the chair to move above the lifting part 105a. Then, the second drive unit 103a is activated, causing the second lead screw 103b to rotate. The rotation of the second lead screw 103b will cause the ball slider 103c to move upward, causing the connecting table 102 to move upward synchronously, and then causing the lifting part 105 to lift the chair and retract it.

[0069] The limiting assembly 106 includes: an upper fixing block 106a, a lower fixing block 106b, a guide shaft 106c, and a guide slider 106d; the upper fixing block 106a is fixed on the bracket 101 and located above the bracket 101; the lower fixing block 106b is fixed on the bracket 101 and located below the bracket 101; the guide shaft 106c is vertically disposed between the upper fixing block 106a and the lower fixing block 106b, and its upper and lower ends are respectively connected to the upper fixing block 106a and the lower fixing block 106b; the guide slider 106d is slidably disposed on the guide shaft 106c, and the guide slider 106d is fixedly connected to the connecting platform 102.

[0070] When the second drive unit 103a is activated to drive the connecting platform 102 to move up and down, in order to increase the stability of the connecting platform 102 when it moves up and down, guide shafts 106c and guide sliders 106d are set around the connecting platform 102 to limit the shaking of the connecting platform 102 during the lifting and lowering process, thereby improving the stability when retrieving the chair.
