DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] like Figure 1 and Figure 2As shown, the present invention provides a technical solution: a parts display stand for automobile teaching, wherein the lower end of the mounting plate 1 is fixedly connected with a plurality of support legs 11, and the lower ends of the plurality of support legs 11 are provided with casters 2, which are convenient for the movement of the display stand. The casters 2 are prior art and can be provided with a brake device so as to fix the casters 2 when necessary to prevent the display stand from rolling at will. A motor 3 is also fixedly connected to the middle part of the lower end of the mounting plate 1, and the output end of the motor 3 is fixedly connected with a connecting tube 4 located in the mounting plate 1, and the outer surface of the connecting tube 4 is fixedly connected with a plurality of mounting rods 41, and a display mechanism 5 is provided at one end of the plurality of mounting rods 41 away from the connecting tube 4, and each display mechanism 5 is used to display a part, and when the motor 3 is working, it will drive the connecting tube 4 to rotate continuously, so that when the connecting tube 4 rotates, it will drive the plurality of display mechanisms 5 to rotate simultaneously through the plurality of mounting rods 41, and the parts to be displayed will rotate with the connecting tube 4 as the axis, and the plurality of mounting rods 41 are provided with mounting grooves at one end away from the connecting tube 4.

[0024] Specifically, Figure 3 As shown, the display mechanism 5 includes a spur gear 52, which is rotatably installed in the corresponding installation groove. The inner surface of the spur gear 52 is fixedly connected with a rotating shaft 51 that passes through the installation rod 41 from top to bottom. The connection relationship between the rotating shaft 51 and the installation rod 41 is a rotating connection. The bottom wall of the inner cavity of the installation disk 1 is provided with an annular groove 12, and the lower end of the rotating shaft 51 is movably installed in the annular groove 12. In addition, an inner gear ring 13 is fixedly connected to the upper part of the inner surface of the installation disk 1, and multiple spur gears 52 are all meshed with the inner gear ring 13. Therefore, when the motor 3 is working and drives the multiple installation rods 41 to rotate, the multiple spur gears 52 will be toggled in the process of contacting with the inner gear ring 13, so that the display mechanism 5 as a whole will rotate around the rotating shaft 51 as the axis while the display parts revolve around the connecting tube 4 as the axis, and the annular groove 12 can provide auxiliary guidance when the rotating shaft 51 revolves.

[0025] Furthermore, two support rods 42 are fixedly connected to the side of the upper end of the mounting rod 41 away from the connecting tube 4, and the upper ends of the two support rods 42 are commonly fixedly connected with a crown gear 53. Therefore, the position between the crown gear 53 and the mounting rod 41 is relatively fixed, while the connection relationship between the rotating shaft 51 and the crown gear 53 is relatively rotating. A horizontal shaft 54 ​​that runs through the rotating shaft 51 is rotatably installed on the upper portion of the outer surface of the rotating shaft 51, and a bevel gear 55 is fixedly connected to one side of the outer surface of the horizontal shaft 54. The bevel gear 55 is adapted to the corresponding crown gear 53. Therefore, when the spur gear 52 rotates with the rotating shaft 51, it will also rotate with the horizontal shaft 54 ​​around the rotating shaft 51 as the axis, and the bevel gear 55 will passively rotate with the horizontal shaft 54 ​​around itself as the axis in the process of passing through the upper surface of the crown gear 53. Both ends of the horizontal shaft 54 ​​are fixedly connected with a first pulley 56, so that the two first pulleys 56 will rotate synchronously with the horizontal shaft 54 ​​when the rotating shaft 51 rotates.

[0026] To rotate the display parts in vertical direction, such as Figure 3 and Figure 4 As shown, a display plate 57 is fixedly connected to the upper end of the rotating shaft 51, and a hollow rod 58 is fixedly connected to the upper end of the display plate 57 corresponding to the position of the two first pulleys 56. A clamping assembly 59 is provided on the upper part of one end of the two hollow rods 58 close to each other. When working, the two clamping assemblies 59 can clamp a displayed spare part together. The second pulley 581 is rotatably installed on the upper part of the inner cavity of the two hollow rods 58. The first pulley 56 and the second pulley 581 on the same side are connected by a belt. Therefore, the two first pulleys 56 and the second pulley 581 will rotate synchronously due to the principle of belt transmission.

[0027] Further, such as Figure 5 The clamping assembly 59 includes a rectangular block 591 rotatably connected to the hollow rod 58. The rectangular block 591 is fixedly connected to the corresponding second pulley 581, so that when the first pulley 56 drives the second pulley 581 to rotate, it will drive the rectangular block 591 to continuously rotate with the second pulley 581 as the axis. The end of the rectangular block 591 away from the hollow rod 58 is provided with two upper and lower arranged slide grooves 592, and the inner surfaces of the two slide grooves 592 are slidably installed with clamping blocks 595. The upper end of the rectangular block 591 is rotatably connected to a rotating rod 593 passing through the two slide grooves 592. The outer surface of the rod 593 is provided with threads in opposite directions at the positions corresponding to the two slide grooves 592, and the upper end of the rotating rod 593 is fixedly connected with a star-shaped handle 594. Therefore, when it is necessary to clamp or loosen parts, the user manually rotates the star handle 594, and can move the two clamping blocks 595 in the direction of approaching or moving away from each other through the two opposite threaded parts on the surface of the rotating rod 593, so as to achieve the purpose of clamping or loosening parts. Therefore, during the continuous rotation of the rectangular block 591, the clamped parts will be continuously rotated in the vertical direction with the second pulley 581 as the axis.

[0028] The working principle of the present invention is as follows: before using the parts display stand for automobile teaching, the user needs to manually rotate the star-shaped handle 594, and move the two clamping blocks 595 toward each other through the two opposite threaded parts on the surface of the rotating rod 593, so as to achieve the purpose of clamping the parts;

[0029] Then, the motor 3 is started. When the motor 3 is working, it will drive the connecting tube 4 to rotate continuously, so that when the connecting tube 4 rotates, it will drive the multiple display mechanisms 5 to rotate simultaneously through the multiple mounting rods 41, so that the displayed parts rotate around the connecting tube 4 as the axis;

[0030] When the motor 3 is working and the multiple mounting rods 41 are rotating, the multiple spur gears 52 will be driven in the process of contacting with the inner gear ring 13, so that the display mechanism 5 as a whole will rotate around the rotating shaft 51 while the display parts revolve around the connecting tube 4 as the axis.

[0031] When the spur gear 52 rotates with the rotating shaft 51, it will also rotate with the horizontal shaft 54 ​​around the rotating shaft 51 as the axis. When the bevel gear 55 passes through the upper surface of the crown gear 53, it will passively rotate with the horizontal shaft 54 ​​around itself, so that the two first pulleys 56 will rotate synchronously with the horizontal shaft 54 ​​when the rotating shaft 51 rotates, and drive the second pulley 581 to rotate through the principle of belt transmission, thereby driving the rectangular block 591 to rotate continuously, and the clamped parts will be displayed by rotating continuously in the vertical direction around the second pulley 581 as the axis.

[0032] To sum up, when the device is working, the displayed parts can revolve around the connecting cylinder 4 as the axis, rotate around the rotating shaft 51 as the axis, and rotate in the vertical direction around the second pulley 581 as the axis. Through the multi-directional rotating parts, all angles of the parts are fully displayed.

[0033] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
