Detailed Description

In order to more clearly illustrate the technical solution of the present invention, the following detailed description is made with reference to the accompanying drawings:

as shown in the figure; the invention relates to an automatic telescopic caster wheel for a medical X-ray machine, which comprises a caster wheel 1, wherein the caster wheel 1 is fixedly arranged at the lower side of a guide sloping block 2 through a bolt, a fixed block 4 is arranged at the upper side of the guide sloping block 2,

and a guide wheel 3 is fixedly arranged between the guide inclined block 2 and the fixed block 4 and on the guide inclined block 2 through bolts.

Further, a spring-fixing sleeve 5 is arranged on the upper side of the fixing block 4, and the spring-fixing sleeve 5 is screwed into the fixing block 4 through threads;

a spring I6 is sleeved on the spring I fixing sleeve 5, and a spring I fixing rod 7 is arranged inside the spring I6 and on one side of the spring I fixing sleeve 5;

a second spring fixing sleeve 11 is further arranged on the other side of the first spring fixing sleeve 5 on the fixing block 4, a second spring 10 is sleeved on the second spring fixing sleeve 11, and a second spring fixing rod 9 is arranged inside the second spring 10 and on one side of the second spring fixing sleeve 11.

Further, a push plate 8 is fixedly arranged between the first spring fixing rod 7 and the second spring fixing rod 9.

Further, a push plate hole is formed in the fixed block 4, and the lower end of the push plate 8 penetrates through the formed push plate hole and is fixedly arranged on the outer wall of one side of the guide inclined block 2 through a screw 12.

Further, the aperture of the push plate hole is larger than the diameter of the push plate 8.

Furthermore, the outer surfaces of the guide inclined block 2 and the fixed block 4 are triangular, and the directions of the guide inclined block and the fixed block are opposite.

Specifically, the structure comprises a caster 1, a guide inclined block 2, a guide wheel 3, a fixed block 4, a first spring fixing sleeve 5, a first spring 6, a first spring fixing rod 7, a push plate 8, a second spring fixing rod 9, a second spring 10, a second spring fixing sleeve 11, a screw 12 and the like;

the caster wheel 1 is fixedly connected to the inclined guide block 2 (arranged at the lower end of the inclined guide block 2) through bolts, and the guide wheel 3 is fixedly connected to the inclined guide block 2 through bolts and has the function of ensuring that the guide wheel 3 rolls smoothly;

screwing a first spring fixing sleeve 5 into the upper side of the fixing block 4 through threads, sleeving a first spring 6 on the first spring fixing sleeve 5, and installing a first spring fixing rod 7 in the first spring 6; a second spring fixing sleeve 11 is fixedly arranged on the upper side of the fixing block 4 at the other side of the fixing block, a second spring 10 is sleeved on the second spring fixing sleeve 11, and a second spring fixing rod 9 is further arranged in the second spring 10;
