[0025] See also Figure 1-10 As shown, the utility model relates to a lifting bracket, including a lifting armrest 1, a lifting mechanism 2, a base fixing rod 3 and a base 4, wherein the base fixing rod 3 is installed on the base 4, and a sliding space is provided in the base fixing rod 3 for providing sliding of the lifting mechanism 2, the lifting armrest 1 is connected to one end of the lifting mechanism 2, and the other end of the lifting mechanism 2 is slidably installed in the sliding space, so that the lifting and lowering functions of the lifting mechanism 2 can be controlled by manipulating the lifting armrest 1.

[0026] In order to improve the overall appearance of the lifting bracket, an outer sleeve 5 is nested and installed at the opening of the base fixing rod 3. The outer sleeve 5 covers the lifting mechanism 2 inside, and the lifting mechanism 2 performs lifting movement in the outer sleeve 5.

[0027] Among them, the lifting mechanism 2 includes a lifting guide rail 21, a guide pulley group, a coil spring 23, a coil spring connector 24 and a fixed ring 25. The fixed ring 25 is installed at the sliding space opening of the base fixing rod 3. The coil spring connector 24 includes a fixing part 241 and a connecting part 242. The fixing part 241 is installed on the fixing ring 25, and the connecting part 242 is arranged in the sliding space. The lifting guide rail 21 passes through the fixing ring 25 and is arranged in the sliding space. The guide pulley group cooperates with the lifting guide rail 21 to be slidably installed inside the sliding space. At least one coil spring 23 is provided on the lifting guide rail 21, and the end part 231 of the coil spring 23 is fixedly connected to the connecting part 242.

[0028] Furthermore, in the present embodiment, a pair of pulley grooves 31, guide grooves 32 and coil spring connecting grooves 33 are provided in the sliding space of the base fixing rod 3, and the pulley grooves 31, guide grooves 32 and coil spring connecting grooves 33 are vertically arranged in the sliding space, and at the same time, the pulley grooves 31, guide grooves 32 and coil spring connecting grooves 33 pass through the openings at both ends of the base fixing rod 3.

[0029] Further, in this embodiment, the lifting rail 21 includes a lifting rod 211 and a sliding part 212, the lifting rod 211 is installed above the sliding part 212, and a guide rail 213 is provided on a common side of the lifting rod 211 and the sliding part 212, wherein the cross section of the guide rail 213 matches the shape of the guide groove 32. In this embodiment, guide pulley groups are provided on both sides of the guide rail 213 of the sliding part 212. When the lifting rail 21 is installed inside the base fixing rod 3, the guide rail 213 can be slidably arranged in the guide groove 32, and the guide pulley group can be slidably installed in the pulley groove 31.

[0030] In this embodiment, the lifting rod 211 passes through the fixing ring 25 and is connected to the lifting handrail 1. The lifting rod 211 is provided with limit members 2111 on both sides close to the sliding portion 212. The lifting handrail 1 controls the lifting rod 211 to move up or down. When the limit member 2111 rises to abut against the fixing ring 25, the fixing ring 25 blocks the limit member 2111 from continuing to move upward, thereby limiting the maximum height to which the lifting guide rail 21 can slide, and at the same time preventing the lifting guide rail 21 from directly sliding out of the base fixing rod 3.

[0031] In this embodiment, the guide pulley group includes a plurality of first pulleys 221 and a plurality of second pulleys 222. The first pulleys 221 slide along the bottom of the pulley groove 31, and the second pulleys 222 slide along the side walls of the pulley groove 31, thereby improving the stability of the lifting guide rail 21 when sliding in the base fixing rod 3.

[0032] In this embodiment, the sliding portion 212 of the lifting guide rail 21 is provided with at least one coil spring installation groove 2122, and the coil spring 23 is installed in the coil spring installation groove 2122. Furthermore, in this embodiment, the coil spring 23 includes an end portion 231 and a winding portion 232, and the winding portion 232 is installed in the coil spring installation groove 2122. The end portion 231 is a straight line design, and the end portion 231 is provided with a connecting port 2311. In addition, the connecting portion 242 of the coil spring connector 24 is provided with a coil spring installation port 2421, and the connecting port 2311 can be connected to the coil spring installation port 2421 through a fastener, so that the end portion 231 and the connecting portion 242 are fixedly connected.

[0033] When the lifting rail 21 is installed inside the base fixing rod 3, the fixing portion 241 of the coil spring connector 24 is installed on the fixing ring 25, the connecting portion 242 is arranged in the coil spring connecting groove 33, and the connecting portion 242 is fixedly connected to the end portion 231 of the coil spring 23. When the lifting rail 21 rises or falls, the coil spring 23 is deformed by the movement of the lifting rail 21, and the end portion 231 is fixed by the coil spring connector 24, so that the coil portion 232 will perform telescopic movement due to the tension. During the lifting and lowering process of the lifting rail 21, the restoring force of the coil spring 23 itself will be equal to the force of the load above the lifting rail 21, thereby realizing the function of adjusting the position at will and temporarily locking.

[0034] The utility model relates to a lifting bracket, which fixes the end portion 231 of a coil spring 23 on a coil spring connector 24. During the lifting process of a lifting guide rail 21, a winding portion 232 of the coil spring 23 will perform a telescopic movement due to a pulling force, wherein the restoring force of the coil spring 23 itself is consistent with the negative gravity above the lifting guide rail 21, so that when adjusting the position, the coil spring 23 also has a temporary locking function and can stay at an arbitrary position, so that the user can freely adjust a more suitable viewing height according to their own needs, giving the user a better use and viewing experience.

[0035] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
