[0002] Sofa is a kind of furniture, mainly used in homes or public places for people to sit or lie down and rest. The main function of the sofa is for people to sit or lie down, for rest, meeting guests or entertainment. It provides a comfortable seat for people to relax in their daily lives. There are many styles and types of sofas, including single sofas, double sofas, three-seater sofas, corner sofas, L-shaped sofas, etc. They can be selected and matched according to the space size and needs of the home or public place, and the sofa feet need to be used to support the installation of the sofa.
[0003] Patent document CN216364428U discloses a sofa leg with casters, which discloses that "it includes a supporting column, rollers are rotatably installed on the left and right sides of the notch, support rings are sleeved on the upper and lower sides of the supporting column, and the support ring can move up and down along the supporting column to support or detach from the ground. A locking device and a transmission device are also provided on the supporting column. First, two rollers are spaced apart at the lower end of the supporting column, and the rollers can be used to facilitate the movement of the sofa, thereby improving the convenience of operation and bringing convenience to the movement of the sofa; in addition, when the supporting ring moves, the transmission device is driven, and the locking device is driven by the transmission device to work, thereby locking the two rollers. At this time, by locking the rollers and supporting the support ring with the ground, the damage to the sofa legs caused by the rollers bearing gravity is avoided, which is beneficial to the protection of the sofa legs."
[0004] However, the sofa leg with casters in the above-mentioned public document mainly considers locking the roller and supporting the support ring with the ground, thereby avoiding the damage of the sofa leg caused by the roller bearing gravity, which is beneficial to the protection of the sofa leg. However, it is not convenient to adjust the angle of the sofa. Because the existing sofa legs cannot conveniently adjust the angle of the sofa, when the angle of the sofa needs to be adjusted again, the sofa needs to be rotated as a whole, which increases the difficulty of adjustment.
[0005] In view of this, it is necessary to develop an automatic twist lock mechanism, so that the angle of the sofa can be adjusted conveniently. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of the utility model are:
[0016] 1. The utility model is convenient for adjusting the angle of the sofa by installing an automatic rotary lock mechanism. The existing sofa legs cannot conveniently adjust the angle of the sofa, and when the angle of the sofa needs to be adjusted again, the sofa needs to be rotated as a whole, which increases the difficulty of adjustment. Therefore, it is necessary to improve this. First, the battery is installed in the battery slot, and the circuit box is supported by the electric push rod to push the power. Then, the control button is pressed to make the electric push rod work and drive the jacking block to be removed from the storage slot. Then, the jacking block is used to support the sofa leg body, so that the other three groups of ordinary sofa legs are in a suspended state, and only one sofa leg body needs to be installed on a sofa. At this time, the sofa is rotated because the other three groups of ordinary sofa legs are in a suspended state. At this time, the sofa is relatively easy to rotate. When rotating, the adjusting stud moves in the adjusting screw groove, so the angle of the sofa is adjusted, and the adjusting stud and the adjusting screw groove lock the angle of the sofa well. After the adjustment is completed, the jacking block is retracted into the storage slot, thereby facilitating the adjustment of the angle of the sofa, saving time and effort.
[0017] 2. The utility model improves the anti-skid ability of the sofa foot body by installing an anti-skid mechanism. The anti-skid performance of the bottom of the existing sofa foot body is not good, which makes the sofa position move easily by manual pushing, so it is necessary to improve this. First, the anti-skid plate is moved to the bottom of the sofa foot body, and then the mounting column is moved into the mounting groove, and then the hemispherical block is squeezed with the inner wall of the mounting groove, the spring is compressed, and the slider moves on the sliding column. When the hemispherical block moves to the outside of the hemispherical groove, the spring resets the hemispherical block to the hemispherical groove, and then the position of the anti-skid plate is fixed. The anti-skid plate is used to improve the anti-skid property of the sofa foot body. At the same time, the anti-skid plate is easy to replace, making later maintenance more convenient.
