background technology:
Operation trolley is a kind of portable medical apparatus and instruments, and patient or other equipment can be pushed to another one point from a point by it.In order to better shift patient, these medical operation go-carts are all provided with universal wheel, but mostly the roller portion of these deflecting rollers is hard material, it compares rub resistance, but the noise produced is also larger, and be all Hard link between these universal wheels and go-cart support, therefore, produce and a bit shake on the patient or equipment that all can be reflected to above go-cart; Although have the universal wheel of shock-proof effect at present on the market, the complicated structure on this universal wheel, and mostly shock-proof spring is oblique, the active force of generation is not remarkable for bradyseism effect yet.But at hospital internal, the environment more needed peace and quiet due to the patient that seeks medical advice is nursed one's health, therefore, these Operation trolley with roller or other Mobile medical equipment are just difficult to the effect meeting quiet shock-absorbing.
summary of the invention:
Technical problem to be solved by this invention is, provide a kind of can reduce noise and have flexible bradyseism effect Operation trolley vibration-proof silent wheel.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of Operation trolley vibration-proof silent wheel, comprise roller, bearing block and location-plate, described roller is connected with bearing block by axle, described location-plate is connected with bearing block by support column, described roller is made up of thrust bearing and the flexible cushion rubber being wrapped in thrust bearing outside, and described axle is connected with the bearing block outside roller through the centre bore of thrust bearing, described support column is made up of sleeve and sleeving connecting rod, described sleeve is fixedly connected with bearing block, its open top, inside is provided with circular cylindrical cavity, described sleeving connecting rod is fixedly connected with location-plate, the rectangular structure of its end face, shock-proof spring is provided with in the cavity of described sleeve, the top of described shock-proof spring is provided with pressing plate, the end face of described pressing plate is provided with the recess coordinated with sleeving connecting rod end face, steering block is provided with above it, the centre of described steering block is provided with the rectangular opening rubbed with sleeving connecting rod side slip, arranged outside has steering bearing interconnective with sleeve inner cavity.
As preferably, the opening of described sleeve is provided with seal cover, and the center of described seal cover is provided with the through hole for interspersed sleeving connecting rod.
As preferably, described seal cover with between sleeve for being threaded.
As preferably, the diameter of described pressing plate is more than or equal to the end face diameter of shock-proof spring and is less than the intracavity diameter of sleeve.
Compared with prior art, usefulness of the present invention is: this Operation trolley vibration-proof silent wheel construction is fairly simple, shock-proof spring can be changed according to bradyseism coefficient, and shock-proof spring is vertical arrangement, and the vibrations that therefore pair roller position produces can be good at scattering, the patient on Operation trolley or equipment is made to produce vibrations, keep stable, meanwhile, roller is made by flexible cushion rubber, reduce the friction on itself and ground, reduce noise.
