Description

Lifting table leg locking piece Technical Field The utility model relates to a table leg connecting piece, in particular to a locking piece suitable for lifting a table leg to adjust lifting height. Background The existing lifting table comprises outer legs connected with foot legs and inner legs connected with a table body, wherein the inner legs are sleeved in the outer legs. In order to meet the adjustment requirements of different heights of the lifting table, various locking structures are arranged at the matching ends or in the matching strokes of the outer legs and the inner legs in the prior art, such as common bolt and positioning hole matching, spring pin and positioning hole matching and the like, and intelligent hydraulic lifting rods, mechanical lifting screws and the like can be matched. The existing locking structures can well realize the functions of lifting height adjustment and lifting locking, but for the technical scheme to be proposed, the existing locking structures are relatively high in cost and relatively complex in structure. Disclosure of utility model In order to solve the problems in the prior art, the utility model provides the lifting table leg locking piece which is low in cost and simple in structure. The technical scheme provided by the utility model is as follows: The lifting table leg locking piece comprises an outer leg and an inner leg sleeved in the outer leg, wherein one end of the outer leg is provided with a locking piece for adjusting the lifting height of the inner leg. The locking piece is provided with a central sleeve body for the inner leg to penetrate, one end of the central sleeve body is provided with a shoulder capable of being carried on the top end face of the outer leg, the side wall of the central sleeve body is provided with an opening and closing part along the height direction of the central sleeve body, two sides of the central sleeve body, which are close to the opening and closing part, are respectively provided with corresponding nut petals, a nut is screwed on the two nut petals, and the central sleeve body can be tightened or loosened through the opening and closing part. According to the utility model, the inner leg is fixed in the outer leg through the central sleeve body with the shoulder and the opening and closing part at the end part of the outer leg, and the inner leg can be tightened or loosened in the outer leg through tightening the nut by tightening the nut flap, so that the lifting adjustment is realized. In the technical scheme, the shape of the center sleeve body is matched with the inner leg and is also equivalent to the shape of the outer leg, the center sleeve body is mainly used for holding or releasing the inner leg to carry out height lifting adjustment, the shoulder can be partially arranged on the top end surface of the outer leg, namely, the top end surface of the outer leg can also be fully distributed, the center sleeve body is mainly used for preventing the center sleeve body from sliding down into the outer leg to play a role of fixing the position when the center sleeve body locks the inner leg, and the opening and closing part is a through seam shape and mainly used for reducing the inner diameter of the center sleeve body and tightening the caliber size of the center sleeve body to hold the inner leg. The nut petals are composed of two half nuts with the size of the spacing opening and closing part, and are fixed on the central sleeve body, and when the nuts are locked, the nut petals are shortened in distance, namely the inner diameter of the central sleeve body is tightened. It is conceivable that the opening and closing portion can achieve the above technical effects even though penetrating the center housing. Preferably, the shoulder is distributed on the top end face of the outer leg, so that not only the fixing strength can be improved, but also the attractiveness of the product can be improved. Preferably, the opening and closing part accounts for 60% -100% of the height of the central sleeve body, and can be arranged from the upper part to the lower part of the central sleeve body or from the lower part to the upper part, so that the caliber of the central sleeve body can be reduced, and the tightening function can be realized. In the above technical schemes, the shoulder can also vertically extend downwards along the outer side wall of the outer leg to form the bending part, so that the fixing strength can be improved, and the aesthetic degree of the product can be improved. Furthermore, in order to prevent the central sleeve body from being separated from the outer leg, at least one release hole is formed in the shoulder, and a clamping table is arranged on the inner wall of the bending part in the direction corresponding to the release hole. The clamping table can only lock the central sleeve body at the port of the outer leg through the inverted tooth on the side wall of the outer leg, and when the cen
