[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4, An adjustable-length building support pole, comprising a support assembly and an adjustment assembly. The support assembly includes a base 1, a support tube 2, and a lifting tube 3. The base 1 is provided with the support tube 2. Guide grooves are provided on the front and rear sides of the support tube 2. Guide blocks 4 slidably connected to the guide grooves are provided on the front and rear sides of the lifting tube 3. The adjustment assembly includes a protective cover 5, a worm gear 6, a worm 7, a handle 8, and a screw rod 9. The protective cover 5 is arranged in a U-shape on the base 1. The worm 7 and two groups of worm gears 6 are arranged inside the protective cover 5. The worm 7 meshes with the two groups of worm gears 6. The handle 8 penetrates through the protective cover 5 and is connected to the worm 7. The screw rods 9 are provided in two groups and are respectively threadedly connected to the corresponding guide blocks 4. The screw rods 9 penetrate through the protective cover 5 and are connected to the centers of the worm gears 6.

[0024] The base 1 serves as the foundation of the entire building support pole. It can be fixed to the ground or other support structures through the mounting holes at the four corners, ensuring that the support pole will not move or tilt during use. The base 1 provides a stable support platform for the upper support tube 2 and lifting tube 3. The support tube 2 is fixed on the base 1, and the guide grooves provided on its front and rear sides provide tracks for the movement of the lifting tube 3. The guide blocks 4 on the front and rear sides of the lifting tube 3 are slidably connected to the guide grooves of the support tube 2, enabling the lifting tube 3 to move up and down only along the direction of the guide grooves, ensuring the linearity and stability of the lifting process. The operator drives the worm 7, which penetrates through the protective cover 5 and is connected to the handle 8, to rotate by turning the friction lines 11 on the handle 8. The worm 7 meshes with the two groups of worm gears 6 inside the protective cover 5. When the worm 7 rotates, it drives the worm gears 6 to rotate. Due to the self-locking property of the transmission between the worm 7 and the worm gears 6, that is, only the worm 7 can drive the worm gears 6 to rotate, and the worm gears 6 cannot drive the worm 7 to rotate, this enables the support pole to remain stable after being adjusted to the required length and will not change its length automatically due to external loads. The two screw rods 9 are respectively threadedly connected to the corresponding guide blocks 4, and the screw rods 9 penetrate through the protective cover 5 and are connected to the centers of the worm gears 6. When the worm gears 6 rotate, they drive the screw rods 9 to rotate. Since the guide blocks 4 are slidably connected to the guide grooves on the support tube 2 and the auxiliary frame 10 on the protective cover 5, restricting the rotational movement of the guide blocks 4, the rotation of the screw rods 9 is converted into a linear movement of the guide blocks 4.

[0025] In this embodiment, an auxiliary frame 10 is further provided on the protective cover 5. The guide block 4 is slidably connected to the auxiliary frame 10, and the screw rod 9 is rotatably connected to the top wall of the auxiliary frame 10. The auxiliary frame 10 provided on the protective cover 5 is slidably connected to the guide block 4, providing additional support and guidance for the screw rod 9. During the movement of the lifting pipe 3, the auxiliary frame 10 can limit the movement direction of the guide block 4, preventing the guide block 4 from being distorted or deformed, and ensuring that the threaded connection between the screw rod 9 and the guide block 4 always remains stable. A reinforcing rib 12 is provided on the base 1 and is connected to the side wall of the auxiliary frame 10 and the protective cover 5. The reinforcing rib 12 provided on the base 1 connects the side wall of the auxiliary frame 10 and the protective cover 5, capable of dispersing and transmitting the force borne by the support rod during use. When the support rod is subjected to an external load, the reinforcing rib 12 can transmit the force to a wider area, reducing local stress concentration and improving the overall strength and stability of the device.

[0026] During actual use, friction lines 11 are provided on the handle 8 to ensure the stability of the drive of the handle 8.

[0027] In this embodiment, a cleaning hole is provided on one side of the support pipe 2 away from the protective cover 5, and a dust-proof cap 13 is provided above the lifting pipe 3 to prevent impurities from entering the lifting pipe 3 and the support pipe 2 from accumulating. The dust-proof cap is detachably connected to the lifting pipe 3, facilitating the assembly of other devices.
