Description

Adjusting structure of dining chair Technical Field The utility model relates to the technical field of dining chairs, in particular to an adjusting structure of a dining chair. Background The dining chair is a chair for dining in a restaurant or a kitchen, is generally matched with a dining table for use, dining current dining chair legs are supported by being in direct contact with the ground, the dining chair legs need to be slid on the ground when the dining chair needs to be moved, the supporting mode (slidable and non-slidable) of the dining chair cannot be switched and adjusted according to a use scene, and in occasions needing to frequently move the dining chair, such as the dining table, when the dining chair needs to be moved from one position to another, the dining chair needs to be pushed or pulled due to the fact that the friction force between the dining chair legs and the ground is large, so that the dining chair is labor-consuming and time-consuming. Disclosure of Invention The utility model aims to provide an adjusting structure of a dining chair, which solves the problems in the prior art. In order to achieve the purpose, the utility model provides the following technical scheme that the adjusting structure of the dining chair comprises: The middle part of the support tube is provided with a pneumatic rod, and the top of the pneumatic rod is rotatably provided with a seat cushion; The landing leg, the landing leg is provided with a plurality of and equidistance rigid couplings in the outside of stay tube, the bottom rigid coupling of landing leg one end has the stabilizer blade, one side rotation of stabilizer blade is connected with the truckle, one side of stabilizer blade is provided with spacing fixed part for the position of fixed truckle switches stabilizer blade or truckle and ground contact. Preferably, the middle part of the air pressure rod is provided with a lifting rod in a lifting manner, the top of the lifting rod is provided with a supporting seat, and the seat cushion is fixedly connected to the top of the supporting seat. Preferably, limiting plates are fixedly connected to two sides of one end of each supporting leg, a protecting shell is connected to the outer side of each supporting leg in a sliding mode, the protecting shell is of an n-shaped structure, and sliding grooves matched with the limiting plates are formed in the inner wall of the protecting shell. Preferably, the end part of the limiting plate is fixedly connected with a limiting baffle plate for limiting the protecting shell, and a limiting notch matched with the limiting baffle plate is formed in the side edge of the protecting shell. Preferably, the bottom of the support leg is fixedly connected with a rubber pad. Preferably, the spacing fixed part comprises a supporting shaft, one end of the supporting leg is fixedly connected with the supporting shaft, two spacing grooves are formed in one end of the supporting shaft, a spacing ring is rotationally connected to the outer side of the supporting shaft, and the top of the caster is rotationally connected with the spacing ring. Preferably, one end of the supporting shaft is rotatably connected with a threaded rod, the outer side of the threaded rod is in threaded connection with a driving plate, one side of the driving plate is fixedly connected with two limiting inserted bars corresponding to the limiting holes, and the limiting groove is in sliding connection with the limiting inserted bars. Compared with the prior art, the dining chair has the beneficial effects that the casters can be locked at the designated positions stably and reliably through the arrangement of the limiting fixing parts when the casters are required to be fixed, so that the safety problem caused by accidental movement of the casters is prevented, the dining chair can be easily moved when required and stably fixed when not required to be moved through flexible switching of the casters and the supporting legs, the practicability and convenience of the dining chair are improved, the protective shell is attractive in appearance, the casters can be effectively shielded and restrained, noise generated by rotating and swinging of the casters when not required is prevented, the stability of the dining chair is enhanced through the rubber pad fixedly connected to the bottoms of the supporting legs, good anti-skid effect is provided, and potential safety hazards caused by sliding are reduced.
