Description

Foot-operated quick lifting movable castor Technical Field The utility model relates to the technical field of casters, in particular to a pedal quick lifting mobile caster. Background At present, the quick lifting mobile castor is mainly used for realizing convenient movement and height adjustment of objects, and the core structure of the quick lifting mobile castor generally comprises a lifting pipe base, a lifting pipe in sliding connection and a castor assembly. The caster needs to meet the functional requirements of quick lifting, stable locking and smooth falling back so as to adapt to the operation requirements of adjusting the height of the object in different application scenes. The existing lifting movable casters are short in lifting distance, inconvenient to put down after lifting, and the buckle plate needs to be pulled forcefully, so that aiming at the current situation, the quick lifting movable casters stepped on by feet are urgently needed to be developed, and the defects in the current practical application are overcome. Disclosure of utility model The utility model aims to provide a foot-operated quick lifting movable castor for solving the problems in the background technology. In order to achieve the above purpose, the present utility model provides the following technical solutions: The utility model provides a quick lifting removes truckle is stepped on to foot, includes lifting pipe base and lifting tubule, the lifting tubule cartridge in the lifting pipe base and with lifting pipe base sliding connection, still include: the lifting pedal is rotationally connected with the lifting pipe base through a bolt A; One end of the rotary driving seat is hinged with the lifting pedal through a bolt C, and the other end of the rotary driving seat is hinged with the lifting small pipe through a bolt D; The falling pedal is rotationally connected with the lifting pipe base through the bolt A; the lifting pipe base is provided with a lifting groove, and the lifting pedal is provided with a limiting groove; The falling pedal is fixedly provided with a bolt B which is inserted into the limit groove and can slide along the limit groove; The bolt D is inserted into the lifting groove and can slide along the lifting groove. As a further scheme of the utility model, the bottom of the lifting pipe base is connected with casters, and the top of the lifting small pipe is fixedly connected with an object connecting seat. As a further scheme of the utility model, a plurality of adjusting holes are longitudinally formed in the pipe wall of the lifting small pipe, and the bolt D is inserted into one of the adjusting holes. As a further scheme of the utility model, the falling pedal is arranged on the inner side of the lifting pedal, and the falling pedal can push the bolt B to slide in the limiting groove when rotating. As a further scheme of the utility model, the lifting pedal and the falling pedal share the bolt A as a rotation center shaft. As a further scheme of the utility model, the object connecting seat and the lifting small pipe are fixedly connected into a whole through welding. As a further scheme of the utility model, the casters are fixedly connected to the bottom of the lifting tube base through screws. As a further proposal of the utility model, the adjusting holes are longitudinally arranged on the pipe wall of the lifting small pipe. Compared with the prior art, the utility model has the beneficial effects that: 1. the operation convenience is improved, namely the functions of one-key lifting and one-key falling are realized through a double-pedal design (a lifting pedal and a falling pedal), and a user can finish height adjustment and unlocking only by stepping on the pedal, so that the operation is time-saving and labor-saving; 2. The self-locking stability is enhanced, namely a negative angle mechanical structure is formed after lifting, so that the object connecting seat can be stably locked under high load, and accidental falling is avoided; 3. The height is flexible and adjustable, a plurality of groups of adjusting holes are longitudinally formed in the lifting small pipe, and the fixed positions of the adjusting bolts D can be adapted to the demands of objects with different heights, so that the application scene is expanded; 4. the lifting pipe base is fixed with the caster screw, the object connecting seat is welded with the lifting small pipe into a whole, and the integral structural strength is improved; 5. the falling mechanism is optimized, namely the falling pedal pushes the bolt B to slide along the limit groove, the linkage rotation driving seat releases the negative angle locking, and the falling can be smoothly carried out depending on the dead weight of the object without additional force application; 6. and the motion track is precisely controlled, namely the vertical motion of the lifting groove guide bolt D is performed, the limiting groove constrains the sliding path
