Technical Field

[0001] This utility model relates to the field of lifting platform technology, specifically a lifting platform for a multifunctional work frame. Background Technology

[0002] Currently, a lifting mechanism needs to be installed at the bottom of the multi-functional work rack to adjust its height and adapt to different working environments.

[0003] CN211354307U discloses an electric multi-purpose lifting mechanism. When a multi-functional work frame is installed on this structure, bolts are used to fix the multi-functional work frame to the lifting platform for adjusting the height of the multi-functional work frame. However, using bolts to fix and disassemble the work frame requires the use of a wrench or other specialized tools. In addition, multiple bolts need to be installed for the stability of the work frame. As a result, the operation of loading, unloading and disassembling multiple bolts involves many steps and is time-consuming, leading to the problem of cumbersome loading and unloading of the work frame. Therefore, those skilled in the art have proposed a lifting seat for a multi-functional work frame. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a lifting seat for a multifunctional work frame, which solves the problems mentioned above.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a lifting seat for a multi-functional work frame, comprising: a multi-functional work frame;

[0026] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.

[0027] like Figure 1-8 As shown, the lifting seat of a multi-functional work frame disclosed herein may include: a multi-functional work frame 11, a fixing mechanism, and a lifting mechanism;

[0028] like Figure 1-4 As shown, the fixing mechanism includes a fixing base 1, a slot 2, a cavity 3, a limiting plate 4, an extension rod 5, a spring 6, a pull ring 7, a plug 8, a clip 9, and a slot 10.

[0029] Two slots 2 are formed on the upper surface of the fixed base 1. Each cavity 3 is formed inside the fixed base 1 and is located on one side of the corresponding slot 2. Each limiting plate 4 is slidably set in the corresponding cavity 3. Each set of two extension rods 5 is installed on the side of the corresponding limiting plate 4. Each pull ring 7 is installed at the end of the corresponding set of extension rods 5 extending to the outside of the fixed base 1. Each spring 6 is sleeved on the corresponding extension rod 5. Each plug 8 is installed on the other side of the corresponding limiting plate 4 and extends to the nearest slot 2. Two clips 9 are installed at the center of the lower surface of the multi-functional work frame 11 and are adapted to the two slots 2. Each slot 10 is formed on the side of the corresponding clip 9 and is adapted to the plug 8.

[0030] When installing the multi-functional work frame 11, simply pull the two pull rings 7 to move the two limit plates 4 away from each other. Each moving limit plate 4 compresses the spring 6, causing the plug-in 8 to move out of the slot 2 and into the cavity 3. Then, insert the two clips 9 of the multi-functional work frame 11 into the two slots 2. When fully inserted, the slot 10 on each clip 9 is aligned with the two plug-ins 8. After that, release the two pull rings 7 to allow all the springs 6 to rebound and move the two limit plates 4 back to their original positions, thereby causing each plug-in 8 to insert into the aligned slot 10 and fix the multi-functional work frame 11 on the fixed base 1. When disassembling the multi-functional work frame 11, simply pull the two pull rings 7 and use the above operation to move the two plug-ins 8 out of the slot 10 and into the cavity 3 to release the fixation of the clips 9. Then, the multi-functional work frame 11 can be removed from the device. The operation is simple and does not require professional tools, making it convenient for users to install and remove the multi-functional work frame 11.

[0031] like Figure 1-4 As shown, the lifting mechanism includes a tool placement plate 12, a support foot 13, a first square tube 14, a second square tube 15, an adjustment hole 16, an adjustment groove 19, a rectangular groove 20, a Z-shaped clamping plate 21, a torsion spring 22, a third square tube 23, a fixing hole 24, and a pin 25.

[0032] The tool placement tray 12 is positioned directly below the fixed base 1. Four support feet 13 are installed at the four corners of the tool placement tray 12. A first square tube 14 is installed on the upper end of the support feet 13. A second square tube 15 is slidably disposed inside the first square tube 14 and adapted to it. Multiple adjustment slots 19 are evenly distributed on the side of the second square tube 15. A rectangular slot 20 is formed on the side of the first square tube 14 and aligned with one adjustment slot 19. A Z-shaped clamping plate 21 is rotatably mounted on the side of the first square tube 14 and positioned within the rectangular slot 20. Below, the upper part of the Z-shaped plate 21 passes through the rectangular groove 20 and is inserted into the aligned adjustment groove 19. The torsion spring 22 is set on the rotating shaft that rotatably connects the Z-shaped plate 21 and the rectangular groove 20. The third square tube 23 is slidably set inside the second square tube 15 and is adapted to it. Multiple adjustment holes 16 are evenly opened on the other side of the second square tube 15. The fixing hole 24 is opened on the side of the third square tube 23 and is close to the lower end and aligned with an adjustment hole 16. The pin 25 is set between the fixing hole 24 and the adjustment hole 16 aligned with it.

[0033] When adjusting the height of the multi-functional work frame 11, press the bottom of the Z-shaped clamp 21 towards the first square tube 14 to make the Z-shaped clamp 21 deflect around the rotation point. While squeezing the torsion spring 22, the upper part of the Z-shaped clamp 21 moves out of the adjustment groove 19, thus releasing the fixation on the second square tube 15. Then, pull up the third square tube 23 to raise the multi-functional work frame 11. After reaching the predetermined height, fine-tune the second square tube 15 so that the rectangular groove 20 aligns with the nearest adjustment groove 19. Then, release the Z-shaped clamp 21, allowing the torsion spring 22 to rebound and cause the upper part of the Z-shaped clamp 21 to re-engage through the rectangular groove 20 and align. Inside the groove 19, the second square tube 15 is fixed. When the upper part of the Z-shaped clamping plate 21 is inserted into the adjustment groove 19 at the bottom of the second square tube 15, and the multi-functional work frame 11 needs to be raised, the pin 25 is pulled out to release the fixation between the third square tube 23 and the second square tube 15. Then, the third square tube 23 is pulled up to continue to drive the multi-functional work frame 11 to rise until the predetermined height is reached. Then, the third square tube 23 is finely adjusted so that the fixing hole 24 is aligned with the nearest adjustment hole 16. Then, the pin 25 is inserted between the fixing hole 24 and the aligned adjustment hole 16 to fix the third square tube 23. The operation is completed.
