There are two track correction blocks symmetrically arranged on both sides of the rotating block. The track correction block is in a shape of expanding from the rotating block to one side. The rotating block is installed on the main body and can deflect left and right and up and down when the main body moves to reduce the friction when the main body slides.

[0008] Preferably, the sliding assistance component includes a guide rail, a roller and a limit block. The main body is located inside the frame and fixedly connected to the support part. The guide rails are arranged on both sides of the main body and fixedly connected to the frame for guiding the main body. The roller is rotatably connected to the main body and inserted into the guide rail to assist the main body in moving up and down. The limit block is fixedly connected to the main body and located between the two guide rails. The limit block contacts the guide rail to assist in guiding the main body.

[0009] Preferably, the rotating block is rotatably mounted on the main body through a bolt. The aperture on the rotating block for accommodating the bolt is larger than the diameter of the bolt. The track correction block is located inside the guide rail and there is a gap between its edge and the inner side wall of the guide rail.

[0010] Preferably, the tension adjustment part includes a tension spring, a pull rope and a moving block. One end of the tension spring is fixedly connected to the frame and is located between the main body and the moving block to provide resistance for the main body. One end of the pull rope is fixedly connected to the main body and the other end is fixedly connected to the moving block. The pull rope passes through the free end of the tension spring and cooperates with the tension spring. The moving block is slidably connected to the frame through a threaded rod threaded thereon.

[0011] Preferably, the tension adjustment part further includes a fixed pulley. The fixed pulley is located above the main body and is rotatably connected to the frame. One end of the pull rope is wound around the fixed pulley and fixedly connected to the main body.

[0012] Preferably, the connection structure includes a connecting rod and a telescopic sliding component. One end of the connecting rod is rotatably connected to the support part and the other end is fixedly connected to the fixed structure of the bearing part through the telescopic sliding component. The telescopic sliding component is installed on the connecting rod for the fixed structure of the bearing part to slide relative to the frame.

[0013] Preferably, the telescopic sliding component includes a bearing rod, a sliding limit piece and a sliding groove. The sliding groove is opened on the connecting rod for accommodating the sliding limit piece. The sliding limit piece is sleeved on the bearing rod to assist the bearing rod in moving.

[0014] Preferably, the sliding limit piece includes a lower limit frame and an upper limit frame. An I-shaped structure sleeved on the bearing rod is formed between the lower limit frame and the upper limit frame.

[0017] The beneficial effects of the present invention are as follows:

[0018] Through the design of the tension spring, the pull rope and the moving block, the present invention can adjust the height of the load-bearing member when load-bearing members of different weights are installed. Moreover, during the movement of the moving block, a tool can be directly used to rotate the threaded rod, so as to achieve the purpose of adjustment without disassembling the frame body.

[0019] The present invention limits the moving direction of the main body by using the rollers arranged on both sides of the main body and the guide rails fixed in the frame body. During the movement of the main body, the auxiliary limit can be carried out again through the limit block arranged between the two guide rails, and the moving direction of the main body is further limited through the arrangement of the limit block and the guide rails.

[0020] Through the use of the rotating blocks arranged on both sides of the main body and the track correction blocks arranged on the rotating blocks, the present invention can reduce the number and time of direct contact between the main body and the track during the up and down movement of the main body. Moreover, the threaded hole connecting the rotating block and the main body is larger than the screw rod for rotational limit. Therefore, during the up and down movement of the main body, the rotating block and the track correction block thereon can tilt up and down or swing left and right, so as to make the plane of the roller or the side of the main body as little in direct contact with the guide rail as possible, and make the curved surface of the roller in contact with the guide rail as much as possible, so as to reduce the friction force during the sliding process.

[0021] The present invention adopts the telescopic sliding assembly arranged in the connecting structure, and through the auxiliary wheel and the chute, the load-bearing rod can move better. At the same time, under the action of the positioning column and the limiting plate, the position of the load-bearing rod can be limited, and it can be fixed when the load-bearing rod is in the appropriate position.

Detailed implementation manners

[0035] The following further elaborates in detail the detailed implementation manners of the present invention in conjunction with the attached drawings.

[0036] Referring to the attached drawings of the specification Figures 1-12 , a display bracket that is convenient for multi-directional adjustment and telescopic, includes a frame body 1, a base 2, a lifting structure, a connection structure, and a carrier fixing structure 3, wherein the base 2 is installed below the frame body 1, and the frame body 1 and the base 2 can be rotatably connected through a rotating shaft provided on the frame body 1, and a corresponding fixed limit structure is provided in the base 2 to be clamped on the plane to be fixed.

[0037] The lifting structure is installed on the frame body 1, and the carrier installed on the carrier fixing structure 3 through the lifting structure can move up and down relative to the frame body 1. The lifting structure includes a support part 4, a sliding part, and a tension adjustment part. The support part 4 is installed on the sliding part, and the support part 4 is moved up and down through the sliding part. The tension adjustment part is installed inside the frame body 1 to adjust the resistance received by the sliding part.

[0038] The support part 4 includes two fins fixedly connected to the sliding part and a rotating shaft installed between the two fins, and the carrier fixing structure 3 can be rotated relative to the frame body 1 through the rotating shaft.

[0039] 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 base for the fins of the support part 4. There are two guide rails 5, which are arranged in parallel on both sides of the main body 6 and 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 movement direction of the main body 6 is limited and guided through the guide rail 5 and the roller 7. Moreover, the sliding friction between the main body 6 and the guide rail 5 can be converted into rolling friction through the roller 7, reducing the friction force between the main body 6 and the guide rail 5.

[0040] The sliding part further includes a friction force assisting structure provided on both sides of the main body 6. The friction force assisting structure is further divided into a rotating block 8 and an orbit correcting block 9. Among them, there are two orbit correcting blocks 9, which are symmetrically arranged on both sides of the rotating block 8. The two orbit correcting blocks 9 expand from the side in contact with the rotating block 8 towards the direction away from each other. Under the action of the orbit correcting block 9 and the rotating block 8, the friction force assisting structure is in a bow shape;

[0041] The rotating block 8 is rotatably connected to the main body 6 through a bolt. There is a gap between the maximum diameter of the orbit correcting block 9 and the inner side 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 through a bolt, and the hole diameter on the rotating block 8 for accommodating the bolt is slightly larger than the diameter of the bolt, and the two are in clearance fit. Therefore, when the main body 6 is close to the guide rail 5, under the action of inertia force, the orbit correcting block 9 will tilt and its edge will contact the inner side wall of the guide rail 5. The clearance fit between the bolt and the accommodating hole on the rotating block 8 can enable the rotating block 8 to swing up and down, thereby reducing the friction force during the up and down movement of the main body 6.

[0042] In order to assist in limiting the sliding of the main body 6, a limiting block 10 is fixedly connected to the main body 6. The limiting block 10 is located between the two guide rails 5 and contacts the outer edge surface of the guide rail 5. The limiting of the limiting block 10 is realized through the two guide rails 5, so that the main body 6 can move better in the vertical direction.

[0043] The tension adjusting 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, which passes through one end of the tension spring 11 and is fixedly connected to the main body 6. The end of the tension spring 11 that cooperates 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, so as to achieve the purpose of providing different degrees of resistance for the main body 6.

[0044] The moving block 13 is slidably connected to the frame body 1. Meanwhile, a threaded rod 14 is rotatably connected to the frame body 1, and the threaded rod 14 is slidably connected to the moving block 13. The up-and-down movement of the moving block 13 is realized by the rotation of the threaded rod 14.

[0045] The tension adjusting part further includes a fixed pulley 15 and a tension spring 11 auxiliary component. The fixed pulley 15 is located above the main body 6. The pulling rope 12 is wound around the fixed pulley 15 and fixedly connected to the main body 6. The fixed pulley 15 is rotatably connected to the frame body 1. The tension spring 11 auxiliary component is arranged on the side where the tension spring 11 is connected to the pulling rope 12, so that one end of the tension spring 11 is better sleeved on the pulling rope 12 through the tension spring 11 auxiliary component.

[0046] The connecting structure includes a connecting rod 16 and a sliding component. One end of the connecting rod 16 is rotatably connected to the supporting part 4, and the other end is connected to the carrier fixing structure 3 through the sliding component. The telescopic sliding component is installed on the connecting rod 16 for the carrier fixing structure 3 to slide relative to the frame body 1.

[0047] The telescopic sliding component includes a bearing rod 17, a sliding limiting part and a sliding groove 18. The sliding groove 18 is opened on the connecting rod 16 for accommodating the sliding limiting part. The sliding limiting part is sleeved on the bearing rod 17 to assist the movement of the bearing rod 17.

[0048] The sliding limiting part includes a lower limiting frame 19 and an upper limiting frame 20. The lower limiting frame 19 and the upper limiting frame 20 form an I-shaped structure sleeved on the bearing rod 17. The connecting rod 16 is located between the lower limiting frame 19 and the upper limiting frame 20. Both the upper limiting frame 20 and the lower limiting frame 19 are slidably connected to the sliding groove 18 through auxiliary wheels 21.

[0049] The sliding limiting part further includes a positioning column 22 and a limiting plate 23. The positioning column 22 is arranged on the bearing rod 17 for positioning the limiting plate 23. The limiting plate 23 is inserted into the upper limiting frame 20 and contacts the outer edge surface of the auxiliary wheel 21. A bolt that is inserted into the bearing rod 17 and threadedly connected to the bearing rod 17 is rotatably connected to the limiting plate 23.

[0050] During the process of rotating the bolt, the purpose of pressing the auxiliary wheel 21 by the limiting plate 23 can be achieved. The limiting and fixing between the upper limiting frame 20 and the lower limiting frame 19 can be directly realized by the pressure applied to the auxiliary wheel 21.

[0051] The bearing rod 17 is connected to the carrier fixing structure 3 through a universal joint 24.

[0052] 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 elaborated here too much.

[0053] When the present invention is in use, the installer first installs and fixes the base 2 at a suitable position on a plane. After the installation is completed, the installer inserts the frame body 1 onto the base 2. Under the action of the rotating shaft on the frame body 1, the frame body 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 are all installed in the frame body 1;

[0054] The installer fixes the support part 4 on the main body 6, and then the installer buckles 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 body 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 worker 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;

[0055] When the workpiece to be carried is installed on the bearing member fixing structure 3, the worker adjusts the resistance of the tension spring 11 by rotating the threaded rod 14, and realizes the hovering of the workpiece to be carried at different heights by changing the resistance of the tension spring 11.

[0056] 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 bearing members of different weights are installed. Moreover, during the movement of the moving block 13, the threaded rod 14 can be directly rotated by using a tool, so as to achieve the purpose of adjustment without disassembling the frame body 1.

[0057] The present invention limits the moving direction of the main body 6 by using the rollers 7 arranged on both sides of the main body 6 and the guide rails 5 fixed in the frame body 1. During the movement of the main body 6, the limiting block 10 arranged between the two guide rails 5 can be used for auxiliary limiting again. The movement direction of the main body 6 is further limited by the arrangement of the limiting block 10 and the guide rails 5.

[0058] 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 using the rotating blocks 8 arranged on both sides of the main body 6 and the track correction blocks 9 arranged on the rotating blocks 8. Moreover, the threaded hole connecting the rotating block 8 and the main body 6 is larger than the screw rod for rotational 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 as to make the plane of the roller 7 or the side of the main body 6 as little in direct contact with the guide rail 5 as possible, and make the curved surface of the roller 7 in contact with the guide rail 5 as much as possible, so as to reduce the friction during the sliding process.

[0059] The present invention uses a telescopic sliding component disposed in the connection structure. Through the auxiliary wheel 21 and the chute 18, the bearing rod 17 can move better. At the same time, under the action of the positioning column 22 and the limiting plate 23, the position of the bearing rod 17 can be limited, and it can be fixed when the bearing rod 17 is in a suitable position.
