The small cart is generally formed by mounting wheels at the bottom of a cabinet body and mounting a pushing handle at the front end of the cabinet body, and can realize the nursing of the hospital cart or the changing and washing of articles in hotels and the like.

The support and the connected mode of the wheel of most small handcart on the market at present adopt and span at the bottom of the cabinet body of the handcart and install a diaphragm, then weld or twist screwed connection the wheel at the lower extreme of iron plate, two problems must be brought about to this kind of connected mode, one is the installation of diaphragm and the cabinet body bottom of the handcart and the installation of wheel and diaphragm, an installation mode has been increased here, and it is inevitable to increase the risk of becoming flexible to have crossed a connection, the second is that this kind of installation mode causes the holding power direction of wheel not on four support columns of handcart easily, and the location experience of installer is examined very much to the installation position of wheel, if positioning deviation, then cause the handcart holding power inhomogeneous easily, then take place certain position fracture of handcart bottom easily for a long time.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects in the prior art, the utility model aims to provide a wheel connecting and supporting mechanism of a trolley, which aims to solve the problems in the background art.

In order to achieve the purpose, the utility model is realized by the following technical scheme: the utility model provides a shallow wheel is connected and supporting mechanism, includes the connection supporting mechanism body, the connection supporting mechanism body includes support column, threaded rod, support and gyro wheel, threaded hole is seted up to the bottom of support column, the bearing is installed on the top of support, the top of bearing is connected with the threaded rod, the bottom cover of threaded rod is equipped with the nut, the gyro wheel is installed to the bottom of support.

As a preferred embodiment of the present invention, a frame is provided at the top end of the support column.

In a preferred embodiment of the utility model, the bracket is connected with the supporting column through a threaded rod and a threaded hole which are matched.

As a preferred embodiment of the present invention, the center points of the threaded hole, the threaded rod and the bearing are all on the same vertical axis.

As a preferred embodiment of the present invention, the bottom end of the bracket is provided with an inclined angle.

The utility model has the beneficial effects that: the connection and support mechanism for the cart wheels comprises a connection and support mechanism body, wherein the connection and support mechanism body comprises a support column, a threaded rod, a nut, a bearing, a support, a roller, a threaded hole and a frame.

1. This shallow wheel is connected and supporting mechanism can install the threaded rod is screwed up to the bottom of the support column of predetermineeing, and the installation location is accurate swift more.

2. This shallow wheel is connected and supporting mechanism has saved this structure of installation of diaphragm, has reduced not hard up chance, uses more firmly.

Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further described with the specific embodiments.

Referring to fig. 1 to 4, the present invention provides a technical solution: the utility model provides a shallow wheel is connected and supporting mechanism, includes the connection supporting mechanism body, the connection supporting mechanism body includes support column 1, threaded rod 2, support 5 and gyro wheel 6, threaded hole 7 is seted up to the bottom of support column 1, bearing 4 is installed on the top of support 5, the top of bearing 4 is connected with threaded rod 2, the bottom cover of threaded rod 2 is equipped with nut 3, gyro wheel 6 is installed to the bottom of support 5.

As a preferred embodiment of the present invention, the supporting column 1 is installed at a position preset at four corners of the bottom of the cart, so as to avoid deviation during installation and positioning, thereby reducing stability.

In a preferred embodiment of the utility model, the bracket 5 is connected with the support column 1 through the matching of the threaded rod 2 and the threaded hole 7.

In a preferred embodiment of the present invention, the center points of the threaded hole 7, the threaded rod 2, and the bearing 4 are all on the same vertical axis, thereby preventing the inclination and the skew.

In a preferred embodiment of the present invention, the bottom end of the bracket 5 is provided with an inclined angle to facilitate the rotation of the bracket 5 and the roller 6 through the bearing 4.

The working principle is as follows: the wheel connecting and supporting mechanism of the trolley mainly comprises supporting columns 1, threaded rods 2, a bracket 5 and idler wheels 6, wherein the supporting and connecting mode of the wheels of most small trolleys on the market at present adopts that a transverse plate is installed at the bottom of a trolley cabinet body in a spanning mode, then the wheels are welded or screwed at the lower end of the transverse plate to be connected, the transverse plate for connection is removed by the device, the idler wheels 6 are directly installed below four supporting columns 1 preset at four corners of the bottom of the trolley through the bracket 5 and the threaded rods 2, the threaded rods 2 are directly screwed in threaded holes 7 through directly tapping in threaded holes 7 at the lower parts of the four supporting columns 1, so that the threaded rods 2 are perpendicular to the trolley and the ground, the trouble in positioning the idler wheels 6 is avoided, in addition, the structure for connecting the transverse plate is omitted, the loosening opportunity is reduced, and during movement, the four idler wheels 6 play a role of stable supporting, make every gyro wheel 6 all can turn to through the bearing 4 of every threaded rod 2 bottom, the nut 3 at bearing 4 top is used for fixing threaded rod 2, prevents not hard up and fixes four support columns 1 through the frame 8 on top, guarantees stability.

While there have been shown and described what are at present considered the fundamental principles and essential features of the utility model and its advantages, it will be apparent to those skilled in the art that the utility model is not limited to the details of the foregoing exemplary embodiments, but is capable of other specific forms without departing from the spirit or essential characteristics thereof.
