Abstract
The utility model discloses a locking device for a supporting pipe. The locking device for the supporting pipe comprises an upper cover plate, a lower cover plate, a threaded rod and a pressing block, wherein the lower cover plate is fixed on a fixed face of the supporting pipe, a threaded rod locating hole is formed in the lower cover plate, one end of the threaded rod is arranged inside the threaded rod locating hole, a threaded rod through hole is formed in the upper cover plate, the threaded rod penetrates through the threaded rod through hole, an internal thread hole is formed in the pressing block, and the other end of the threaded rod is screwed into the internal thread hole. When the locking device for the supporting pipe is used, the distance between the upper cover plate and the lower cover plate can be adjusted by screwing or loosening the pressing block, and thus conversion between locking and unlocking of the supporting pipe clamped between the upper cover plate and the lower cover plate can be achieved. Due to the fact that an eccentric structure is omitted, the problem that the eccentric size is difficult to control is solved. Meanwhile, a threaded connection mode can be unlocked only when correct operation is carried out, and thus potential safety hazards of automatic unlocking of an eccentric locking device are eliminated. The utility model further provides a folding table.
