Description

Improved steel core rubber wheel

Technical Field

The utility model relates to a steel core rubber wheel, specific improved generation steel core rubber wheel that can realize direction locking that says so.

Background

The steel core rubber wheel is widely used in various industries, the structure of the existing steel core rubber wheel is simple, the wheel is free at any time, and although the requirement on the moving flexibility is met when the wheel moves, when the steel core rubber wheel is used, such as a goods shelf and equipment, the steel core rubber wheel often moves in a long straight line or in an arc shape, at the moment, the moving efficiency of the fixed wheel is higher than that of the non-fixed wheel, particularly, when the wheel moves, the wheel is easy to incline at an angle if the ground is uneven, and at the moment, the direction needs to be corrected and adjusted under the action of external force, so that the wheel is labor-consuming.

In summary, there is a need in the industry for an improved steel core rubber wheel that can be universally and flexibly moved and can be angularly fixed when needed.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the not enough that prior art exists, provide an improved generation steel core rubber wheel that possesses steel core rubber wheel fixed function.

In order to achieve the above object, the utility model adopts the following technical scheme: an improved steel core rubber wheel comprises a bottom plate, a rotary table, a support, a locking device and a wheel body, wherein the bottom plate is hinged on the rotary table and can rotate around the rotary table; a plurality of positioning holes are distributed on the bottom plate along the ring shape; the bracket is fixedly connected with the turntable; the wheel body is arranged on the bracket through a rotating shaft, and the locking device is arranged on the turntable and is in alignment fit with the positioning hole on the bottom plate; the locking device comprises a shell, an electromagnetic assembly, a reset spring and a bolt, wherein the bolt is sleeved with the reset spring and then is installed in the shell; the lower part of bolt is connected the cooperation with the electromagnetism subassembly, and when the electromagnetism subassembly circular telegram electrified magnetism, the bolt was inhaled perpendicular rebound by magnetism, inserts in the locating hole, makes between bottom plate and carousel radially keep fixed, when the magnetism is inhaled and is disappeared, receives reset spring and self gravity combined action, and the bolt is down, gets back to initial position, makes steel core rubber wheel resume the degree of freedom.

Furthermore, a storage battery is arranged in the shell, a control key is arranged outside the shell, and the working state of the electromagnetic assembly can be controlled through the control key.

Further, the outer edge of the wheel body is made of rubber.

The utility model discloses simple structure, reasonable in design can realize through above-mentioned structure that quick wheel direction is fixed, satisfies the motion of fixed circuits such as long straight line, major diameter line, labour saving and time saving.

Detailed Description

For the convenience of further understanding, the present invention will be further described by referring to the embodiments shown in the drawings.

Example (b):

as shown in fig. 1 and 2, the utility model comprises a bottom plate 1, a turntable 2, a bracket 3, a locking device 4 and a wheel body 5, wherein the bottom plate 1 is hinged on the turntable 2 and can rotate around the turntable 2; a plurality of positioning holes 6 are distributed on the bottom plate 1 in an annular manner; the bracket 3 is fixedly connected with the turntable 1; the wheel body 5 is arranged on the bracket 3 through a rotating shaft, and the locking device 4 is arranged on the turntable and is in contraposition fit with the positioning hole 6 on the bottom plate 1; the locking device 4 comprises a shell, an electromagnetic assembly, a reset spring and a bolt, the bolt is sleeved with the reset spring and then is installed in the shell, a retainer for keeping the bolt to move vertically is further arranged in the shell, and an opening for extending the bolt is formed in the upper end of the shell; the lower part and the electromagnetic component of bolt are connected the cooperation, and when the electromagnetism subassembly circular telegram was magnetized, the bolt was inhaled perpendicular rebound by magnetism, inserts in locating hole 6, makes between bottom plate 1 and carousel 2 radially keep fixed, when the magnetism was inhaled and is disappeared, receives reset spring and self gravity combined action, and the bolt is down, gets back to initial position, makes the steel core rubber wheel resume the degree of freedom.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are used merely for convenience of description and for simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention. Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.
