DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0023] like Figure 1 and Figure 2 As shown, a part lifting device for automobile teaching includes a hydraulic cylinder 1. The hydraulic cylinder 1 is a prior art. The output end of the hydraulic cylinder 1 can lift the parts when it is extended or retracted. The front end of the output end of the hydraulic cylinder 1 is rotatably installed with a mounting bracket 11. The design of the rotatable connection between the output end of the hydraulic cylinder 1 and the mounting bracket 11 enables the device to rotate the lifted parts when in use. A first mounting plate 12 is fixed to the front end of the mounting bracket 11. A plurality of mounting components 2 are arranged at the front end of the first mounting plate 12, wherein the first mounting plate 12 is used for the installation of the mounting component 2, and since the first mounting plate 12 is circular in design, it is convenient to flip the parts.

[0024] like Figure 3 and Figure 4As shown, the mounting assembly 2 includes a first mounting hole 21 opened at the front end of the first mounting plate 12, and two support rings 22 are fixed on the inner surface of the first mounting hole 21, and a rotating tube 23 is rotatably mounted between the two support rings 22, wherein the two support rings 22 are used for the installation of the rotating tube 23, and the design of the two support rings 22 leaves a gap between the rotating tube 23 and the first mounting hole 21, and the gap is used to facilitate the mutual friction between the arc-shaped limit block 28 and the inner wall of the first mounting hole 21, so that the rotating tube 23 is fixed relative to the first mounting hole 21, and an adjusting button 24 is also rotatably mounted on the rear end of the rotating tube 23, and due to the friction between the rotating tube 23 and the adjusting button 24, the rotating tube 23 can drive the adjusting button 24 to rotate when it rotates, and the rotating tube 23 can also rotate relative to the adjusting button 24, and an extension rod 25 located in the rotating tube 23 is fixed to the front end of the adjusting button 24, and the adjusting button 24 is fixedly connected with the extension rod 25, so that the extension rod 25 can rotate relative to the rotating tube 23 when the adjusting button 24 rotates.

[0025] In addition, a transmission gear 26 is fixed to the outer surface of the extension rod 25, so that when the extension rod 25 rotates, it can drive the transmission gear 26 to rotate, so that the transmission gear 26 can rotate relative to the rotating tube 23, and two transmission racks 27 meshing with the transmission gear 26 are also slidably installed on the inner surface of the rotating tube 23. The transmission racks 27 are meshed with the transmission gear 26, so that when the transmission gear 26 rotates, the two transmission racks 27 can move in opposite directions. The two transmission racks 27 both penetrate the rotating tube 23, and arc-shaped limit blocks 28 are fixed at the left and right ends of the transmission racks 27. When the two transmission racks 27 move in opposite directions, the arc-shaped limit blocks 28 can be squeezed toward the first mounting hole 21, so that the rotating tube 23 is fixed relative to the first mounting hole 21, and a fixing component 3 is also provided at the end of the rotating tube 23 away from the first mounting plate 12.

[0026] When the device is in use, the parts to be lifted are first placed at the front end of the first mounting plate 12, and then the fixing component 3 is rotated to facilitate the placement of the parts. After the fixing component 3 fixes the parts, the transmission gear 26 is driven to rotate by rotating the adjusting knob 24. When the transmission gear 26 rotates, it engages with the two transmission racks 27, so that the two transmission racks 27 move in opposite directions, further making the arc-shaped limit block 28 and the inner wall of the first mounting hole 21 squeeze each other, so that the rotating tube 23 is fixed relative to the first mounting hole 21, and further making the fixing component 3 fixedly connected relative to the first mounting plate 12, so as to facilitate the lifting of the parts. At the same time, due to the design that the fixing component 3 can rotate relative to the first mounting plate 12, multiple fixing components 3 can fix different parts, so as to facilitate the lifting of the device.

[0027] like Figure 5 and Figure 6 As shown, the fixing assembly 3 includes a second mounting plate 31 fixedly connected to the rotating tube 23, so that the second mounting plate 31 can rotate when the rotating tube 23 rotates relative to the first mounting plate 12. When the rotating tube 23 is fixed relative to the first mounting plate 12, the second mounting plate 31 is fixed relative to the first mounting plate 12. A second mounting hole 32 is also provided at one end of the second mounting plate 31. The second mounting hole 32 is located on the side of the second mounting plate 31 away from the dot, so that the position of the second mounting hole 32 can be changed when the second mounting plate 31 rotates. At the same time, through the mutual cooperation between multiple second mounting plates 31, the distance between multiple limit rods 34 required to be used can be adjusted, so that the device can be suitable for different parts. Two first limit grooves 33 are symmetrically provided on the inner wall of the second mounting hole 32, and the limit rod 34 is movably installed on the inner surface of the second mounting hole 32. When the device is in use, the limit rod 34 is inserted into the second mounting hole 32.

[0028] Furthermore, two first limit blocks 35 adapted to the first limit grooves 33 are fixed to the outer surface of the limit rod 34, and a second limit groove 36 adapted to the first limit block 35 is also provided at one end of the second mounting plate 31. When the limit rod 34 is inserted into the second mounting hole 32, the first limit block 35 is first inserted into the first limit groove 33, and then the limit rod 34 is rotated so that the two first limit blocks 35 are completely located in the second limit groove 36, thereby preventing the limit rod 34 from moving forward and backward. An external thread is also provided on the side of the outer surface of the limit rod 34 away from the rotating tube 23, wherein the external thread is used for the installation of a nut. A threaded hole is also provided on the end of the limit rod 34 away from the rotating tube 23, wherein the threaded hole is used for installing a screw. The design of the external thread and the threaded hole allows the device to be suitable for the installation of different parts when in use.

[0029] Furthermore, in order to facilitate the installation of the nut and the screw, the limiting rod 34 is prevented from rotating when the nut or the screw is installed on the limiting rod 34, thereby affecting the installation of the nut and the screw. Figure 6 As shown, two second limit blocks 37 are symmetrically installed on the inner surface of the second limit groove 36, wherein the second limit block 37 is used to limit the first limit block 35 to prevent the limit rod 34 from rotating when installing or removing nuts and screws on the limit rod 34, thereby affecting the normal operation of the device.

[0030] The specific implementation of this embodiment is as follows: when the device is in use, the second mounting plate 31 to be used is first rotated, and then the adjusting button 24 is rotated. The adjusting button 24 causes the transmission gear 26 to rotate relative to the rotating tube 23 through the extension rod 25. When the transmission gear 26 rotates, it meshes with the transmission rack 27, so that the two transmission racks 27 move in opposite directions, further causing the arc-shaped limit block 28 and the first mounting hole 21 to squeeze each other, so that the rotating tube 23 is fixedly connected relative to the first mounting plate 12, and then the limit rod 34 is inserted into the second mounting hole 32 after adjustment, and then the limit rod 34 is rotated so that the first limit block 35 does not overlap with the first limit groove 33, so as to prevent the limit rod 34 from moving forward or rightward when the device is in use. At the same time, due to the design of the second limit block 37 limiting the first limit block 35, it can also prevent the limit rod 34 from rotating when installing or removing the nut or screw, thereby affecting the installation of the nut and the screw.

[0031] The parts to be lifted are mounted on the outer surfaces of multiple limit rods 34, which fix the parts. At the same time, the design of multiple limit rods 34 makes it possible for the direction displayed by the device when lifting the parts to be the same as the direction in which the parts are installed (that is, the trainees can clearly observe the general shape of the parts), which is convenient for observation and maintenance, and the parts are fixed by nuts or screws.

[0032] It should be noted that the specific installation method, circuit connection method and control method of the hydraulic cylinder 1, the adjusting button 24, etc. in the present invention are all conventional designs and will not be elaborated in detail in the present invention.
