Referring specifically to the drawings, the number of supporting blocks 341 may be set to one, two, or more than two. When the supporting block 341 on the back of the caster connecting seat 34 is completely rotated and opened by the caster assembly 3, the supporting block 341 contacts the back of the cart bottom plate 1 to limit the rotation opening angle of the caster assembly 3, so that the stability of the cart structure in the completely rotated and opened state of the caster assembly 3 is improved, and the carrying capacity of the cart is ensured.
The back of the cart bottom plate 1 is provided with a pull rod connecting seat 11 and a buckle 12, the pull rod 4 is rotatably arranged on the pull rod connecting seat 11, and the pull rod 4 is clamped in the buckle 12. The fully-folded trolley is further provided with a pull rod 4 convenient to pull, and the pull rod 4 rotates, folds and stores through a pull rod connecting seat 11 and locks a folding state through buckling with a buckle 12. The pull rod 4 is located folding support subassembly 2 top when accomodating to under buckle 12's support, can not be close to cart bottom plate 1 back further, folding support subassembly 2 is effectively protected, guarantees that folding state's full folding shallow is not fragile folding control mechanism.
The casters 35 are universal casters, so that the cart can be conveniently moved on one hand, and on the other hand, the casters 35 are attached to the cart bottom plate 1 when being stored.
Working principle: the specific folding process of the caster assembly 3 is as follows: the two control rods 23 are manually operated to move towards each other, so that the locking rods 22 connected with the end parts of the control rods 23 are retracted, the end parts of the locking rods 22 are separated from the locking holes 311 on the rotating control rods 31, the locking rods 22 unlock the rotating control rods 31, and the first springs 33 which are stretched and deformed at the moment recover to deform, so that the rotating control rods 31 and the casters 35 at the two ends rotate towards one side of the folding bracket assembly 2 and fold and store, and the casters 35 are attached to the back surface of the bottom plate 1 of the cart without manual folding.
The specific unfolding process of the caster assembly 3 is as follows: with the caster assembly 3 in the folded state, since the end of the lock lever 22 contacts the arc surface of the side wall of the rotation control lever 31 at this time, the rotation control lever 31 is not locked, and the elastic member at the rear end of the lock lever 22 is in a compressed state. Thus, the rotation control lever 31 can be rotated directly by 90 degrees, so that the caster assembly 3 is rotated open. In the process of rotating and opening the rotation control rod 31, one end of the first spring 33 is fixed with the rotation connecting sleeve 211, the position is unchanged, and the other end of the first spring 33 rotates along with the rotation control rod 31 through the spring fixing sleeve 32, so that the first spring 33 is stretched and deformed. When the rotation control rod 31 is completely opened, the locking hole 311 on the rotation control rod 31 is aligned with the locking rod 22, and the locking rod 22 stretches out and is inserted into the locking hole 311 under the action of the elastic force of the elastic element, so that the position of the caster assembly 3 is locked, and the cart can be pushed stably.
The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
