Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-4 As shown, this utility model is a height-adjustable steel structure support frame, including a telescopic support assembly 1, a restraining hinge assembly 2 installed in the middle of the bottom of the telescopic support assembly 1, a clamping ring assembly 4 fixedly installed on the top of the telescopic support assembly 1, a movable fixing assembly 3 fixedly installed on the bottom of the telescopic support assembly 1, and a convenient switch assembly 5 rotatably installed on one side of the clamping ring assembly 4.

[0027] The convenient switch assembly 5 includes a limit seat 501, which is fixedly installed inside the rotating groove 4031. A limit screw 502 is rotatably installed in the middle of the limit seat 501. A pull ring 505 is fixedly installed on the top of the limit screw 502. A limit plate 503 is installed in the middle of the limit screw 502. A fastening nut 504 is correspondingly provided on the top of the limit plate 503.

[0028] By installing the convenient switch assembly 5 on the device, the device can be easily locked and deployed during steel pipe installation, ensuring ease of use.

[0029] The telescopic support assembly 1 includes pneumatic telescopic outer rods 101, and telescopic inner rods 102 are installed inside the three pneumatic telescopic outer rods 101. A connecting shaft 103 is fixedly installed on the top of the telescopic inner rods 102. The telescopic support assembly 1 is composed of pneumatic telescopic outer rods 101 and telescopic inner rods 102. By inflating and deflating the pneumatic telescopic outer rods 101, the telescopic inner rods 102 can be driven to extend and retract within the pneumatic telescopic outer rods 101, thereby realizing the adjustment of the overall height of the tripod.

[0030] The restraining hinge assembly 2 includes connecting hinges 201. Three connecting hinges 201 are respectively limited and installed on the bottom inner side of the pneumatic telescopic outer rod 101. The other end of the connecting hinge 201 is connected to a restraining rod 202. A tension spring 203 is fixedly installed in the middle of the restraining rod 202. The other end of the restraining rod 202 is connected to one side of the central circular plate 205 through a limiting ring 204. The restraining hinge assembly 2 plays an auxiliary stabilizing role. The connecting hinges 201 are installed on the bottom inner side of the pneumatic telescopic outer rod 101. The tension spring 203 is set in the middle of the restraining rod 202 connected to the other end of the connecting hinge 201. When the height of the tripod changes, the tension spring 203 applies a restraining force to the pneumatic telescopic outer rod 101 through the restraining rod 202 to maintain the stability of the tripod.

[0031] The movable fixing assembly 3 includes a mounting base plate 301, which is fixedly installed at the bottom of three pneumatic telescopic outer rods 101. A rotating clamping plate 302 is rotatably mounted on one side of the bottom of the mounting base plate 301, while a threaded lifting rod 304 is threadedly mounted on the other side. A fixing suction cup 305 is fixedly mounted at the bottom of the threaded lifting rod 304. A moving wheel 303 is fixedly mounted on the inner side of the rotating clamping plate 302. In the movable fixing assembly 3, the mounting base plate 301 serves as the basic load-bearing component, installed at the bottom of the three pneumatic telescopic outer rods 101. The moving wheel 303, fixedly mounted on the inner side of the rotating clamping plate 302, allows the tripod to move easily on the ground. When the tripod needs to be fixed, rotating the threaded lifting rod 304 lowers the fixing suction cup 305 at its bottom, using atmospheric pressure to firmly adhere the fixing suction cup 305 to the ground, achieving stable fixing of the tripod.

[0032] The clamping ring assembly 4 includes a mounting top plate 401, which is fixedly mounted on the top of three connecting shafts 103. A limiting clamp 402 is fixedly mounted at the bottom center of the mounting top plate 401, and a limiting support plate 403 is fixedly mounted on the top of the mounting top plate 401. A limiting shaft 404 is fixedly mounted on one side of the top of the limiting support plate 403. A merging half-ring 405 is rotatably mounted on the top of the limiting shaft 404. The limiting clamp 402 and the central circular plate 205 mutually limit each other. The clamping ring assembly 4 is used to clamp items. The mounting top plate 401 is fixed on the top of the three connecting shafts 103, and the merging half-ring 405 is rotatably mounted on the limiting shaft 404 on the top of the limiting support plate 403. Items can be placed between the merging half-ring 405 and the limiting support plate 403.

[0033] The outer side of the limiting plate 403 is provided with a rotating groove 4031, and the corresponding side of the combined semi-ring 405 is also provided with a movable cavity.

[0034] In the movable fixing assembly 3 of this device, the mounting base 301 serves as the basic load-bearing component and is installed at the bottom of the three pneumatic telescopic outer rods 101. The movable wheels 303, which are limited and installed on the inner side of the rotating clamp 302, allow the tripod to move easily on the ground. When it is necessary to fix the tripod, rotating the threaded lifting rod 304 causes the fixing suction cup 305 at its bottom to descend, using atmospheric pressure to firmly adhere the fixing suction cup 305 to the ground, thus achieving a stable fixation of the tripod.

[0035] The telescopic support assembly 1 consists of a pneumatic telescopic outer rod 101 and a telescopic inner rod 102. By inflating or deflating the pneumatic telescopic outer rod 101, the telescopic inner rod 102 can be driven to extend or retract within the pneumatic telescopic outer rod 101, thereby adjusting the overall height of the tripod. Simultaneously, the restraining hinge assembly 2 provides auxiliary stability. A connecting hinge 201 is installed on the inner bottom of the pneumatic telescopic outer rod 101, and a tension spring 203 is installed in the middle of the restraining rod 202 connected to the other end of the connecting hinge 201. When the tripod height changes, the tension spring 203 applies a restraining force to the pneumatic telescopic outer rod 101 through the restraining rod 202, maintaining the stability of the tripod.

[0036] The clamping ring assembly 4 is used to clamp items. The mounting top plate 401 is fixed to the top of the three connecting rotating shafts 103. The limiting rotating shaft 404 on the top of the limiting tray 403 rotates to install the merging half ring 405, allowing items to be placed between the merging half ring 405 and the limiting tray 403. The limiting seat 501 in the convenient switch assembly 5 is fixed in the rotating groove 4031. Rotating the limiting screw 502 can drive the limiting plate 503 to move. The limiting plate 503 is fixed by the fastening nut 504, thereby tightening the merging half ring 405 and firmly clamping and fixing the items.

[0037] In the workflow, the movable wheels 303 of the movable fixing assembly 3 are placed on the ground, and the tripod is moved to the desired position using the wheels 303. At this time, the fixing suction cup 305 on the threaded lifting rod 304 is in a raised state and not in contact with the ground. Rotating the threaded lifting rod 304 causes the fixing suction cup 305 to gradually descend until it is in close contact with the ground. Continuing to rotate the threaded lifting rod 304, the air inside the fixing suction cup 305 is squeezed out, and atmospheric pressure is used to adhere it to the ground, completing the fixation of the tripod.

[0038] Based on actual usage needs, the height of the telescopic bracket assembly 1 is adjusted. Air is inflated into the pneumatic telescopic outer rod 101, causing the telescopic inner rod 102 to extend upwards under air pressure, increasing the height of the tripod. Air is then released, causing the telescopic inner rod 102 to retract under its own weight and the force spring 203, lowering the tripod height. During height adjustment, the force spring 203 of the restraining hinge assembly 2, through the restraining rod 202 and connecting hinge 201, maintains restraint on the pneumatic telescopic outer rod 101, ensuring tripod stability. The item to be clamped is placed on the limiting plate 403, and the merging half-ring 405 is rotated to close with the limiting plate 403, enclosing the item. The limiting screw 502 of the convenient switch assembly 5 is rotated, causing the limiting plate 503 to move, pressing the merging half-ring 405 onto the item. Finally, the limiting plate 503 is fixed using the fastening nut 504, completing the clamping and fixing of the item.
