DETAILED DESCRIPTION

[0020] The specific implementation modes of the present invention are further described in detail below in conjunction with the accompanying drawings.

[0021] Refer to the instruction manual Figure 1-12 A display stand that is easy to adjust in all directions and is retractable, includes a frame 1, a base 2, a lifting structure, a connecting structure and a bearing fixing structure 3, wherein the base 2 is installed under the frame 1, and the frame 1 and the base 2 can be rotatably connected through a rotating shaft arranged on the frame 1, and a corresponding fixed limiting structure is arranged in the base 2, which can be clamped on the plane to be fixed.

[0022] The lifting structure is installed on the frame 1, and the bearing member installed on the bearing fixing structure 3 through the lifting structure can move up and down relative to the frame 1. The lifting structure includes a supporting part 4, a sliding part and a tension adjusting part. The supporting part 4 is installed on the sliding part, and the supporting part 4 is moved up and down through the sliding part. The tension adjusting part is installed inside the frame 1 to adjust the resistance of the sliding part.

[0023] The supporting part 4 includes two fins fixedly connected to the sliding part and a rotating shaft installed between the two fins, and the rotating shaft can realize the rotation of the supporting component fixing structure 3 relative to the frame 1.

[0024] The sliding part includes a guide rail 5, a main body 6 and a roller 7. The main body 6 is installed in the frame 1 to provide a fixed foundation for the fins of the support part 4. There are two guide rails 5. The two guide rails 5 are arranged in parallel on both sides of the main body 6 and are fixedly connected to the frame 1. The roller 7 is rotatably connected to the main body 6 and inserted into the guide rail 5. The moving direction of the main body 6 is limited and guided by the guide rail 5 and the roller 7. The sliding friction between the main body 6 and the guide rail 5 can be converted into rolling friction by the roller 7, thereby reducing the friction between the main body 6 and the guide rail 5.

[0025] The sliding part also includes a friction auxiliary structure arranged on both sides of the main body 6, and the friction auxiliary structure is divided into a rotating block 8 and a track correction block 9, wherein the track correction blocks 9 are two and symmetrically arranged on both sides of the rotating block 8, and the two track correction blocks 9 expand from the side in contact with the rotating block 8 to the direction away from each other. Under the action of the track correction block 9 and the rotating block 8, the friction auxiliary structure is in a bow-tie shape; The rotating block 8 is rotatably connected to the main body 6 via bolts, and there is a gap between the maximum diameter of the track correction block 9 and the inner wall of the guide rail 5. During the up and down movement of the main body 6, since the rotating block 8 is rotatably connected to the main body 6 via bolts, and the hole diameter on the rotating block 8 for accommodating the bolts is slightly larger than the diameter of the bolts, the two are in a clearance fit. Therefore, when the main body 6 is located close to the guide rail 5, the track correction block 9 will tilt under the action of inertia force and its edge will contact the inner wall of the guide rail 5. The clearance fit between the bolts and the accommodating holes on the rotating block 8 can enable the rotating block 8 to swing up and down, thereby reducing the friction during the up and down movement of the main body 6.

[0026] In order to assist the limited sliding of the main body 6, a limit block 10 is fixedly connected to the main body 6. The limit block 10 is located between the two guide rails 5 and contacts the outer edge surface of the guide rail 5. The limit block 10 is limited by the two guide rails 5 so that the main body 6 can move better in the vertical direction.

[0027] The tension adjustment part includes a tension spring 11, a pull rope 12 and a moving block 13. One end of the pull rope 12 is fixedly connected to the moving block 13, and the other end of the pull rope 12 is a free end that passes through one end of the tension spring 11 and is fixedly connected to the main body 6. One end of the tension spring 11 used in conjunction with the pull rope 12 is sleeved on the pull rope 12, and the pull rope 12 can move freely at this end. The other end of the tension spring 11 is fixedly connected to the frame 1. By adjusting the position of the moving block 13, the tension spring 11 can be stretched or relaxed, thereby achieving the purpose of providing different degrees of resistance to the main body 6.

[0028] The moving block 13 is slidably connected to the frame body 1 , and a threaded rod 14 is rotatably connected to the frame body 1 . The threaded rod 14 is slidably connected to the moving block 13 , and the moving block 13 is moved up and down by the rotation of the threaded rod 14 .

[0029] The tension adjustment part also includes a fixed pulley 15 and a tension spring 11 auxiliary component, the fixed pulley 15 is located above the main body 6, the pull rope 12 is wound around the fixed pulley 15 and fixedly connected to the main body 6, wherein the fixed pulley 15 is rotationally connected to the frame 1, and the tension spring 11 auxiliary component is arranged on the side where the tension spring 11 is connected to the pull rope 12, through the tension spring 11 auxiliary component, one end of the tension spring 11 is better fitted on the pull rope 12.

[0030] The connection structure includes a connection rod 16 and a sliding assembly. One end of the connection rod 16 is rotatably connected to the support part 4 and the other end is connected to the carrier fixing structure 3 via the sliding assembly. The telescopic sliding assembly is installed on the connection rod 16 for the carrier fixing structure 3 to slide relative to the frame 1.

[0031] The telescopic sliding assembly includes a bearing rod 17 , a sliding limiter and a sliding groove 18 . The sliding groove 18 is provided on the connecting rod 16 for accommodating the sliding limiter. The sliding limiter is sleeved on the bearing rod 17 for assisting the bearing rod 17 in moving.

[0032] The sliding limit member includes a lower limit frame 19 and an upper limit frame 20. The lower limit frame 19 and the upper limit frame 20 form an I-shape that is mounted on the load-bearing rod 17. The connecting rod 16 is located between the lower limit frame 19 and the upper limit frame 20. The upper limit frame 20 and the lower limit frame 19 are both slidably connected to the slide groove 18 via auxiliary wheels 21.

[0033] The sliding limiter also includes a positioning column 22 and a limiting plate 23. The positioning column 22 is arranged on the load-bearing rod 17 for positioning the limiting plate 23. The limiting plate 23 is inserted into the upper limit frame 20 and contacts the outer edge surface of the auxiliary wheel 21. The limiting plate 23 is also rotatably connected to a bolt inserted into the load-bearing rod 17 and threadedly connected to the load-bearing rod 17.

[0034] In the process of rotating the bolt, the limiting plate 23 can be used to press the auxiliary wheel 21 , and the upper limiting frame 20 can be directly limited and fixed between the lower limiting frame 19 by the pressure applied to the auxiliary wheel 21 .

[0035] The support rod 17 is connected to the support component fixing structure 3 via a universal joint 24 .

[0036] The carrier fixing structure 3 is used to fix the object to be carried. The base 2 and the carrier fixing structure 3 are relatively mature existing technologies and will not be described in detail here.

[0037] When the present invention is used, the installer first installs and fixes the base 2 at a suitable position on the plane. After the installation is completed, the installer plugs the frame 1 into the base 2. Under the action of the rotating shaft on the frame 1, the frame 1 can rotate along the rotating shaft. At this time, the tension spring 11, the fixed pulley 15, the moving block 13, the main body 6, the roller 7 and the friction auxiliary structure have all been installed in the frame 1. The installer fixes the support part 4 on the main body 6, and then fastens the connecting rod 16 with the support part 4. Under the action of the rotating shaft in the support part 4, the connecting rod 16 can rotate relative to the frame 1. Under the action of the telescopic sliding assembly on the connecting rod 16, the bearing member fixing structure 3 can be moved. When it moves to a suitable position, the staff tightens the bolt to limit the position of the bearing rod 17 through the limiting plate 23 to prevent the position of the bearing rod 17 from moving; When the load-bearing member is installed on the load-bearing member fixing structure 3 , the staff adjusts the resistance of the tension spring 11 by rotating the threaded rod 14 , and the load-bearing member can be suspended at different heights by changing the resistance of the tension spring 11 .

[0038] Through the design of the tension spring 11, the pull rope 12 and the moving block 13, the present invention can adjust the height of the bearing member when the bearing members of different weights are installed, and during the movement of the moving block 13, the threaded rod 14 can be directly rotated using a tool, thereby achieving the purpose of adjustment without disassembling the frame 1.

[0039] The present invention limits the moving direction of the main body 6 by using rollers 7 arranged on both sides of the main body 6 and guide rails 5 fixed in the frame 1. During the movement of the main body 6, auxiliary limiting can be performed again by a limit block 10 arranged between the two guide rails 5. The moving direction of the main body 6 is further limited by the setting of the limit block 10 and the guide rail 5.

[0040] The present invention can reduce the number and time of direct contact between the main body 6 and the track during the up and down movement of the main body 6 by adopting rotating blocks 8 arranged on both sides of the main body 6 and track correction blocks 9 arranged on the rotating blocks 8. In addition, the threaded hole connecting the rotating block 8 and the main body 6 is larger than the screw used for rotation limiting. Therefore, during the up and down movement of the main body 6, the rotating block 8 and the track correction block 9 thereon can tilt up and down or swing left and right, so that the plane of the roller 7 or the side of the main body 6 is in direct contact with the guide rail 5 as little as possible, and the curved surface of the roller 7 is in contact with the guide rail 5 as much as possible, so as to reduce the friction during the sliding process.

[0041] The present invention adopts a telescopic sliding component arranged in the connecting structure, and the auxiliary wheel 21 and the slide groove 18 are used to enable the load-bearing rod 17 to be moved better. At the same time, the position of the load-bearing rod 17 can be limited under the action of the positioning column 22 and the limit plate 23, and the load-bearing rod 17 can be fixed when it is in a suitable position.
