Description

Technical Field

[0001] The utility model relates to the technical field of cultural and tourism product display, and specifically, to a guide wheel fine-tuning device applied to a channel steel as a guide rail foundation. Background Technique

[0002] Cultural and tourism products are generally local special products. In some tourist attractions, display machines are usually set up, and the display machines usually have a lifting function of vertically moving along a fixed path.

[0003] When implementing a lifting guiding method in the prior art, the display machine is installed on a placement plate, channel steel wheels are installed on both sides of the placement plate, and the channel steel wheels are installed on the basic frame of the channel steel guide rail. The channel steel wheels are directly embedded inside the channel steel to achieve the guiding function. One or two channel steel wheels are arranged in each channel steel to achieve the sliding function. However, due to the tolerances of the wheels themselves and the dimensions of the channel steel, there will actually be a relatively large gap within the sliding range and there is no angle adjustment function. In view of this, we propose a guide wheel fine-tuning device applied to a channel steel as a guide rail foundation. Content of the Utility Model

[0004] The purpose of the utility model is to provide a guide wheel fine-tuning device applied to a channel steel as a guide rail foundation to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, one of the purposes of the utility model is to provide a guide wheel fine-tuning device applied to a channel steel as a guide rail foundation, including a bottom plate. Symmetrically and fixedly connected to the upper surface of the bottom plate are channel steel guide rails. A placement plate is arranged between the two channel steel guide rails. Symmetrically and fixedly connected to both ends of the placement plate are shells. On one side of the shell close to the channel steel guide rail, there are four guide wheel bodies. The side wall of the guide wheel body is in contact with the inner wall of the channel steel guide rail. A fine-tuning mechanism is arranged between the four guide wheel bodies and the shell. The fine-tuning mechanism is used to adjust the position of the guide wheel body on one side of the shell.

[0006] As a further improvement of this technical solution, the fine-tuning mechanism includes a force-bearing arm rotatably connected to the inner wall of the shell. A universal ball seat is arranged inside the force-bearing arm. A universal ball nut is slidably connected to the inner wall of the universal ball seat. One end of the universal ball nut is fixedly connected to a matching screw. The matching screw is threadedly connected to the side wall of the shell. The guide wheel body is rotatably connected to one side of the force-bearing arm.

[0007] As a further improvement of this technical solution, the guide wheel body is a frustum-shaped structure placed laterally, and the diameter of the guide wheel body on the side close to the placement plate is larger than the diameter of the side far from the placement plate.

[0008] As a further improvement of the technical solution, the four universal ball nuts are respectively located at positions close to the four corners inside the housing, and the guide wheel body on the force arm and the universal ball nut are at the same height.

[0009] As a further improvement of the technical solution, one end of the mating screw away from the universal ball nut extends to the outside of the housing and is fixedly connected with an external hexagonal block. The force arm is of an L-shaped structure, and a reinforcing rib is fixedly connected between the vertical section and the horizontal section of the force arm.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] The guide wheel fine-tuning device applied to the channel steel rail as the guide rail foundation can make the part of the mating screw inside the housing extend or shorten by rotating the mating screw, and then make the universal ball nut drive the force arm to rotate limitedly, fine-tuning the position of the guide wheel, reducing the gap between the guide wheel and the inner wall of the channel steel rail, improving the stability when the placing plate ascends and descends. After the bionic machine is installed on the upper surface of the placing plate, the bionic machine can be accurately positioned within the specified space to meet the accurate installation requirements.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment 1

[0021] Please refer to Figures 1 - 5 As shown, this embodiment provides a guide wheel fine-tuning device applied to a channel steel rail foundation. It includes a bottom plate. On the upper surface of the bottom plate, channel steel rails 1 are symmetrically and fixedly connected. A placement plate is arranged between the two channel steel rails 1. At both ends of the placement plate, shells 2 are symmetrically and fixedly connected. On one side of the shell 2 close to the channel steel rail 1, there are four guide wheel bodies 4. The side wall of the guide wheel body 4 is in contact with the inner wall of the channel steel rail 1. A fine-tuning mechanism 3 is arranged between the four guide wheel bodies 4 and the shell 2. The fine-tuning mechanism 3 is used to adjust the position of the guide wheel body 4 on one side of the shell 2. By adjusting the position of the guide wheel body 4, the circumferential side walls of the eight guide wheel bodies 4 are respectively in close contact with the inner side walls of the two channel steel rails 1, realizing the guiding function, enabling the placement plate to only move vertically up and down between the two channel steel rails 1, and at the same time eliminating the large gap between the guide wheel body 4 and the channel steel rail 1 caused by the tolerance of the guide wheel body 4 and the dimensional error of the channel steel rail 1, so that the placement plate can be accurately positioned between the two channel steel rails 1.

[0022] In order to fine-tune the position of the guide wheel body 4 on one side of the shell 2, the structure of the fine-tuning mechanism 3 is refined as follows. The fine-tuning mechanism 3 includes a force-bearing arm 31 rotatably connected to the inner wall of the shell 2. A universal ball seat is opened inside the force-bearing arm 31. A universal ball nut 32 is slidably connected to the inner wall of the universal ball seat. One end of the universal ball nut 32 is fixedly connected with a matching screw 33. The matching screw 33 is threadedly connected to the side wall of the shell 2. The guide wheel body 4 is rotatably connected to one side of the force-bearing arm 31. When the matching screw 33 is rotated, through the threaded connection between the matching screw 33 and the shell 2, the part of the matching screw 33 inside the shell 2 extends or shortens. The matching screw 33 that expands and contracts inside the shell 2 drives the universal ball nut 32 to move synchronously. Then, the universal ball nut 32 drives the force-bearing arm 31 to rotate. During the rotation of the force-bearing arm 31, the universal ball nut 32 rotates synchronously inside the universal ball seat. The rotating force-bearing arm 31 drives the guide wheel body 4 to move, thereby adjusting the position of the guide wheel body 4 on one side of the shell 2, making all four guide wheel bodies 4 in close contact with the inner wall of the channel steel rail 1, reducing the gap between the circumferential side wall of the guide wheel body 4 and the inner wall of the channel steel rail 1, and improving the stability of the placement plate during vertical movement.

[0023] In order to adjust the position of the guide wheel body 4 so that after the guide wheel body 4 is in close contact with the inner wall of the channel steel guide rail 1, the horizontal movement of the placement plate in the direction close to or away from the channel steel guide rail 1 is restricted. The guide wheel body 4 is a frustum-shaped structure placed laterally, and the diameter of the side of the guide wheel body 4 close to the placement plate is larger than the diameter of the side away from the placement plate. When the placement plate moves horizontally in the direction close to or away from the channel steel guide rail 1, the inner wall of the channel steel guide rail 1 restricts the guide wheel body 4 from penetrating into the channel steel guide rail 1, thereby restricting the horizontal movement of the placement plate and the guide wheel body 4.

[0024] The four universal ball nuts 32 are respectively located at positions close to the four corners inside the housing 2. The guide wheel body 4 on the force arm 31 and the universal ball nut 32 are at the same height, so that the distance between the four guide wheel bodies 4 on one side of the housing 2 is as large as possible. After the four guide wheel bodies 4 are inserted into the channel steel guide rail 1, the occupied space of the guide wheel body 4 in the channel steel guide rail 1 is increased, and the ability of the placement plate to resist the impact force in the horizontal direction is improved. By setting the universal ball nut 32 at the same height as the guide wheel body 4 and using the lever principle, the position of the guide wheel body 4 can be adjusted more labor-savingly by adjusting the position of the universal ball nut 32.

[0025] One end of the mating screw 33 away from the universal ball nut 32 extends to the outside of the housing 2 and is fixedly connected with an external hexagonal block, which is convenient for the user to use a hand-held tool to twist the mating screw 33. The force arm 31 is an L-shaped structure, and a reinforcing rib is fixedly connected between the vertical section and the horizontal section of the force arm 31. The universal ball nut 32 is arranged on the horizontal section of the force arm 31. The L-shaped force arm 31 can reduce the volume of the force arm 31 while meeting the setting requirements of the universal ball nut 32, achieving weight reduction, reducing the force required to rotate the force arm 31, and the setting of the reinforcing rib enhances the structural strength of the force arm 31.

[0026] In summary, the working principle of this solution is as follows: In actual application, refer to Figure 5, A, B, C, and D respectively correspond to four mating screws 33. When the mating screws 33 are rotated, due to the threaded connection between the mating screws 33 and the housing 2, the part of the mating screws 33 inside the housing 2 extends or contracts. The telescopic mating screws 33 inside the housing 2 drive the universal ball nut 32 to move synchronously. Furthermore, the force arm 31 is driven to rotate limitedly through the universal ball nut 32. When the A and C mating screws 33 are turned, the force arms 31 corresponding to A and C respectively drive the two guide wheel bodies 4 to rotate, increasing the distance between the two guide wheel bodies 4 at the same height. Similarly, turning the B and D mating screws 33 can also increase the distance between the two guide wheel bodies 4 at the same height, enabling the two guide wheel bodies 4 at the same height to come into contact with the inner wall of the channel steel guide rail 1. When the A and D mating screws 33 are turned, the force arms 31 corresponding to A and D respectively drive the two guide wheel bodies 4 to rotate, enabling the four guide wheel bodies 4 to achieve fine adjustment of the angle in the clockwise and counterclockwise directions. Similarly, when the B and C mating screws 33 are turned, the four guide wheel bodies 4 can also achieve fine adjustment of the angle in the clockwise and counterclockwise directions, enabling the two diagonal guide wheel bodies 4 to come into contact with the inner wall of the channel steel guide rail 1. According to the size of the gap position between the guide wheel body 4 and the inner wall of the channel steel guide rail 1 during actual use, the position of the guide wheel body 4 is adjusted so that the eight guide wheel bodies 4 respectively come into contact with the inner walls of the two channel steel guide rails 1, improving the stability when the placement plate moves vertically. After the bionic machine is installed on the upper surface of the placement plate, the bionic machine can be accurately positioned within the specified space, meeting the requirements of precise installation.
