[0033] In one embodiment of the present invention, Figures 1 to 5 As shown, a rotating support assembly that is easy to install is provided, including: a support tube 100, a fixing component 200 and a locking component 300, wherein the fixing component 200 is detachably connected to the end of the support tube 100; the locking component 300 is arranged at the end of the support tube 100 away from the fixing component 200; wherein the locking component 300 includes a telescopic edge rod 310, a fixing joint 320 and an adjusting knob 330, the fixing joint 320 is rotatably connected to the opening position of the support tube 100, the telescopic edge rod 310 is slidably connected to the fixing joint 320, and the adjusting knob 330 is sleeved on the telescopic edge rod 310, the adjusting knob 330 is detachably connected to the fixing joint 320 and can lock the telescopic edge rod 310 at a preset position of the fixing joint 320, the telescopic edge rod 310 is adapted to the inner hole shape of the support tube 100, and when the telescopic edge rod 310 rotates, the telescopic edge rod 310 rotates synchronously with the support tube 100.

[0034] Another embodiment of the present invention provides a study table, comprising the aforementioned conveniently installed rotating support assembly.

[0035] Specifically, the rotating support assembly is independent of the table legs during the packaging and transportation process, which enables convenient packaging and transportation. When assembly is required, the user first detachably installs the fixing component 200 on the end of the support tube 100, and then installs it on one of the table legs through the integrally connected support tube 100 and the fixing component 200; then the telescopic edge rod 310 is inserted into the inner hole of the support tube 100, and the adjusting knob 330 is installed on the fixing joint 320, and the telescopic edge rod 310 is driven to move to the preset position. Finally, the adjusting knob 330 is rotated to lock the position of the telescopic edge rod 310 to complete the installation. Compared with the prior art in which the two ends of the rotating shaft are designed as screws or threaded joints The structure is convenient for consumers to install, but during the process of consumers assembling the threaded or screw structure, due to the lack of professional installation tools by consumers, the installation effect is poor, resulting in an unstable structure of the study table and a decline in the market reputation of the product. The embodiment of the utility model provides a rotating support assembly and a study table that are easy to install.

The number of the abutment blocks 322 is multiple groups, and the multiple groups of abutment blocks 322 are spaced apart at the end openings of the connecting sleeve 321. The connecting sleeve 321 is fixedly arranged at the end of the support tube 100. A locking groove 323 is formed between the abutment blocks 322 and is concentric with the connecting sleeve 321. The inner ring of the connecting sleeve 321 and the locking groove 323 allow the telescopic edge rod 310 to pass through the sliding The adjusting knob 330 is detachably connected to the connecting sleeve 321 and can drive the end of the abutting block 322 toward the inner side of the locking groove 323, so that the end of the abutting block 322 abuts against the fixed edge rod 220; in this embodiment, the abutting block 322 and the connecting sleeve 321 are integrally formed by injection molding, and the plastic material has a certain elastic deformation recovery function. After the diameter adjusting knob 330 is driven, the abutting block 322 is deformed toward the inner side of the locking groove 323, and then abuts against the edge rod to achieve locking.

[0041] like Figures 1 to 5 As shown, in another embodiment of the present invention, the connecting sleeve 321 includes a first connecting ring 324 and a second connecting ring 325. The first connecting ring 324 is provided at the end of the support tube 100 away from the fixing component 200, and the second connecting ring 325 is provided at the end of the first connecting ring 324 away from the support tube 100.

The abutment block 322 is provided at the end of the second connecting ring 325 away from the first connecting ring 324. The adjusting knob 330 is provided with a thread groove adapted to the external thread. The use of a threaded structure is conducive to preventing the adjusting knob 330 from being reversely driven by the abutment block 322, thereby improving the locking effect.

[0042] like Figures 1 to 5As shown, in another embodiment of the present invention, the adjustment knob 330 is configured as a sleeve-shaped structure, the thread groove is formed on the inner ring of the adjustment knob 330, and a raised ring is provided at the end of the inner ring of the adjustment knob 330. The cross-section of the abutment block 322 is configured as a right-angled triangle structure, and the end of the abutment block 322 closest to the raised ring is a narrow end. When the adjustment knob 330 rotates along the thread groove, the inner wall of the raised ring abuts the narrow end of the abutment block 322 and drives the abutment block 322 toward the locking groove 323. The telescopic ridge rod 310 is a hexagonal ridge rod, and the inner hole of the support tube 100 is a hexagonal hole that matches the shape of the telescopic ridge rod 310. The inclined surface of the abutment block 322 is disposed away from the locking groove 323.
