[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0016] Please see Figure 1-3 This utility model provides a prefabricated assembly frame that is easy to disassemble and has a precisely adjustable height. It includes several sets of frame components. Each frame component includes a first upright 1, a second upright 2, and a support base 3. The top of the first upright 1 is provided with a groove 10 that matches the second upright 2. The bottom of the second upright 2 is located inside the groove 10, and the second upright 2 is slidably connected to the groove 10. The support base 3 is installed on the top of the second upright 2. Short internal threaded sleeves 5 are welded to the outer walls of the four sides of the first upright 1. An assembly component is provided between every two adjacent sets of frame components. Each assembly component includes a long internal threaded sleeve 4 and two threaded shafts 11. The threaded shafts 11 are adapted to the long internal threaded sleeve 4. The two threaded shafts 11 are located on both sides inside the long internal threaded sleeve 4, and the threaded shafts 11 are threadedly connected to the long internal threaded sleeve 4. One end of the threaded shaft 11 outside the long internal threaded sleeve 4 is inside the short internal threaded sleeve 5, and the threaded shaft 11 is adapted to the short internal threaded sleeve 5. In this technical solution, by placing the long internal threaded sleeve 4 between two adjacent uprights 1, and then rotating the threaded shaft 11 so that one end is screwed into the corresponding short internal threaded sleeve 5, the connection between the two uprights 1 can be completed. This gives the jig a convenient disassembly and assembly function, and makes it easy to adjust the assembly distance of each jig component, making it flexible and convenient to use.

[0017] In some technical solutions, such as Figure 1 , Figure 3 and Figure 5 As shown, the bottom of the second upright 2 is provided with a threaded hole 13. A lead screw 12 matching the threaded hole 13 is rotatably installed inside the slide groove 10. The upper end of the lead screw 12 is inside the threaded hole 13, and the thread helix angle of the lead screw 12 is less than the equivalent friction angle. A bevel gear 21 is sleeved and fixedly installed on the lower part of the lead screw 12. A control box 6 is fixedly connected to the front side of the first upright 1. A large spur gear 24 and a small spur gear 25 are provided inside the control box 6. The large spur gear 24 and the small spur gear 25 are meshed and connected. A rotating shaft 23 is fixedly installed on the front side of the small spur gear 25. The front end of the rotating shaft 23 passes through the front side of the control box 6 and is rotatably installed with the control box 6. A handwheel 7 is fixedly installed on the front end of the rotating shaft 23. A transmission shaft 22 passes through and is fixedly installed in the middle of the large spur gear 24. The transmission shaft 22 is rotatably installed with the control box 6. A bevel gear 20 is fixedly installed at one end of the transmission shaft 22 inside the slide groove 10. The bevel gear 20 is meshed and connected with the bevel gear 21.

[0018] In use, the handwheel 7 rotates the shaft 23, which drives the transmission shaft 22 to rotate at a reduced speed through the small spur gear 25 and the large spur gear 24. This, in turn, drives the bevel gear 20 to rotate at a reduced speed. The bevel gear 20 and the bevel gear 21 drive the lead screw 12 to rotate. The lead screw 12 and the threaded hole 13 can then drive the upright 2 to move vertically along the slide groove 10, which can both adjust the height of the support base 3 and increase the accuracy of the height adjustment of the support base 3.

[0019] In some technical solutions, such as Figure 1 and Figure 4 As shown, the four outer walls of the upper part of the upright 2 are all fixedly connected with connecting ears 16, and bolts 17 are threaded through and connected to the connecting ears 16. The bottom of the support base 3 is fixedly connected with four mounting internal thread sleeves 18 that match the bolts 17, and the upper end of the bolts 17 is inside the mounting internal thread sleeves 18.

[0020] In use, the upper end of the bolt 17 can be unscrewed from the inside of the internal threaded sleeve 18 to disconnect the connection between the support base 3 and the upright 2, making it convenient to install and disassemble the support base 3 and thus easy to replace different support bases 3.

[0021] In some technical solutions, such as Figure 3As shown, a positioning hole 14 is provided in the middle of the top of the upright 2, and a positioning shaft 15 that matches the positioning hole 14 is fixedly connected in the middle of the bottom of the support base 3. The positioning shaft 15 is located inside the positioning hole 14.

[0022] In use, the positioning effect of the positioning shaft 15 and the positioning hole 14 increases the accuracy of the installation of the support base 3.

[0023] In some technical solutions, such as Figure 4 As shown, the top of the support base 3 has several grooves 19.

[0024] When in use, the top of the support base 3 is made more slip-resistant by multiple grooves 19.

[0025] In some technical solutions, such as Figure 1 As shown, a base 8 is welded to the bottom of the upright 1, and mounting holes 9 are provided at the four corners of the base 8.

[0026] When in use, the mounting holes 9 on the base 8 make it easy to fix the jig assembly to the ground.

[0027] Working principle: During installation, the long internal threaded sleeve 4 is placed between two adjacent uprights 1, and then the threaded shaft 11 is rotated so that one end is screwed into the corresponding short internal threaded sleeve 5, completing the connection between the two uprights 1. The support base 3 is placed on top of the upright 2, so that the positioning shaft 15 enters the positioning hole 14, and then the bolt 17 is rotated so that its upper end enters the installation internal threaded sleeve 18, completing the installation of the support base 3. This completes the assembly of the jig components. During use, the handwheel 7 is used to rotate the rotating shaft 23. The rotating shaft 23 drives the transmission shaft 22 to rotate at a reduced speed through the small spur gear 25 and the large spur gear 24, thereby driving the bevel gear 20 to rotate at a reduced speed. The bevel gear 20 and the bevel gear 21 drive the lead screw 12 to rotate. The lead screw 12 and the threaded hole 13 can then drive the upright 2 to move vertically along the slide groove 10, which can both adjust the height of the support base 3 and increase the accuracy of the height adjustment of the support base 3.

[0028] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
