Abstract
Claims
1. A detachable counterweight device, the device comprising a device housing and a counterweight disposed within the housing, characterised in that: The shell is formed by four side frames connected to each other. Multiple load-bearing frames are set inside the shell. Support columns and counterweights are installed on the load-bearing frames. The support columns are located in the middle and protrude above to connect the umbrella pole body. The counterweights are located around the support columns and are provided with cover plates. The cover plates are fixed to the side frames by fasteners and have through holes in the middle from which the support columns protrude.
2. The detachable counterweight device of claim 1, wherein: The inner sidewall of the frame is provided with multiple horizontal and vertical reinforcing ribs, and the left and right sides are provided with 45-degree arc-shaped mounting edges. The adjacent mounting edges are spliced together to form a 90° corner. The outer side of the spliced corner is an arc or right angle structure. The mounting edges on the left and right sides are installed together by connectors or mortise and tenon structures, and a connecting groove is provided at the connection or on each sidewall of the frame for installing the load-bearing frame.
3. The detachable counterweight device of claim 2, wherein: The load-bearing frame consists of two sections arranged in an X or cross structure. A support column is fixed in the middle of the X or cross structure with bolts. A protective cover is installed around the support column. At least one counterweight is placed around the protective cover. A cover plate is installed on top of the counterweight.
4. The detachable counterweight device of claim 3, wherein: Two counterweights are provided, which are installed on the left and right sides of the protective cover respectively. A notch is opened in the middle for placing the protective cover. Two symmetrical cover plates are opened above the protective cover and the counterweights respectively. A notch is also opened in the middle of the cover plates for placing the support column.
5. The detachable counterweight device of claim 4, wherein: The support column consists of a bottom turntable, a support rod, a decorative cover, and a rotating cover. The bottom of the support rod has a base plate, which is the same size as the turntable and is fixed to the turntable with bolts. A decorative cover is fitted onto the support rod and is fixed to the notch between two cover plates with bolts, serving as a fixed connector at the joint of the two cover plates. A large through hole is provided in the middle of the decorative cover to facilitate the rotation of the support rod within the large through hole. The rotating cover is fitted onto the support rod and covers the decorative cover. The turntable also has a limit device.
6. The detachable counterweight device of claim 5, wherein: The limiting device is a limiting foot pedal. A toothed groove is formed on the base plate. A limiting head with rebound is installed at the bottom of the limiting foot pedal. When the limiting foot pedal is stepped on backward, the limiting head leaves the toothed groove. The rotating support column drives the turntable to rotate in a circle. When the limiting head is inserted into the toothed groove, the turntable restricts movement and fixes it. The limiting foot pedal also extends out of the cover plate through the through hole arranged on the cover plate, and a foot pedal surface is provided at the end.
7. The detachable counterweight device of claim 6, wherein: The support columns are arranged at an angle or vertically, and are hollow inside to accommodate the umbrella pole body.
