Description

Technical Field

[0001] The utility model relates to the technical field of casters, in particular to a high-load transport cart caster. Background Art

[0002] Casters include movable casters and fixed casters. Movable casters, also called universal wheels, have a structure that allows 360-degree rotation; fixed casters, also called fixed casters, have no rotating structure and cannot turn. Generally, two fixed wheels and two universal wheels are set on a trolley, which are used together to facilitate the movement of the trolley.

[0003] When the trolley is in use, its weight is completely applied to the casters. When the cargo placed on the trolley is heavy, the casters will be subjected to greater force, which may easily lead to deformation and damage of the casters, thus affecting the normal use of the trolley. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a high-load transport cart caster, which can improve the load-bearing capacity of the caster, and the caster bracket is not easy to deform, which can extend the service life of the caster.

[0009] On the basis of the above scheme and as a preferred scheme of the above scheme: the chassis is provided with an assembly hole, and the chassis is fixedly connected to the mounting bracket or the chassis and the mounting bracket are rotatably connected via a bearing.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. There are double mounting positions on the mounting bracket, which can be used to install two sets of casters to share the pressure borne by a single caster, which can effectively improve the overall load-bearing capacity; double-layer support plates are set on both sides of the mounting bracket, and reinforcing ribs are set at the junction of the support plate and the top plate, which can effectively prevent the mounting bracket from deformation and ensure that the casters are suitable for high-load transport carts.

[0012] 2. Each set of caster brackets is equipped with a shock-absorbing assembly, which includes a shock-absorbing plate and a shock-absorbing spring. The caster is installed at the front end of the caster bracket, and the shock-absorbing spring acts on the rear end of the caster bracket. The two form a seesaw structure, and the shock is absorbed through the swinging motion of the caster bracket to prevent the caster from being damaged due to vibration when working on uneven ground.

DETAILED DESCRIPTION

[0018] In the description of the present invention, it should be noted that directional words, such as the terms "center", "lateral (X)", "longitudinal (Y)", "vertical (Z)", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of narrating the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific protection scope of the present invention.

[0019] In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features. Therefore, the definition of "first" and "second" features can explicitly or implicitly include one or more of the features. In the description of the utility model, the meaning of "several" and "a number" is two or more, unless otherwise clearly and specifically defined.

[0020] See the attached drawings. The high-load transport cart caster described in this embodiment includes a chassis 1 and a mounting bracket 2. The chassis 1 is provided with a mounting hole 11, and can be mounted under the bottom plate of the cart by fasteners. If it is a fixed caster, the chassis 1 is fixedly connected to the mounting bracket 2. If it is a movable caster, the chassis 1 is rotatably connected to the mounting bracket 2 through a bearing.

[0021] The mounting bracket 2 includes a horizontally arranged top plate 21 and a vertically arranged support plate 22 and a partition plate 23. The support plate 22 has four pieces, which are arranged in two groups on both sides of the top plate 21. The partition plate 23 has two pieces, which are located between the two groups of support plates 22 and vertically connected to the top plate 21. In order to prevent the support plate 22 and the partition plate 23 from being deformed by force, reinforcing ribs 24 are provided at the connection between the support plate 22, the partition plate 23 and the top plate 21.

[0022] The support plate 22 and the partition plate 23 form a mounting position, that is, two mounting positions arranged side by side are provided on the mounting bracket 2. A set of caster assemblies 3 are installed in each mounting position, which can share the pressure borne by a single caster and effectively improve the overall bearing capacity of the caster.

[0023] The caster assembly 3 includes two caster brackets 31 and a caster 32. The caster bracket 31 is a sheet-shaped folded line structure. The middle bending portion of the caster bracket 31 is rotatably mounted on a rotation shaft 25 that penetrates the support plate 22 and the partition plate 23. The caster bracket 31 can swing around the rotation shaft 25. The caster 32 is rotatably mounted between the ends of the two caster brackets 31. The top ends of the two caster brackets 31 are equipped with a shock absorbing assembly 4.

[0024] The shock absorbing assembly 4 includes a shock absorbing plate 41 and a shock absorbing spring 42. The shock absorbing plate 41 is rotatably installed between the top ends of the two caster brackets 31, and a spring mounting column 43 is provided on the shock absorbing plate 41; a limit plate 26 is rotatably installed between the partition plate 23 and the support plate 22, and a through hole is provided on the limit plate 26 for the spring mounting column 43 to pass through. The shock absorbing spring 42 is sleeved on the spring mounting column 43, and both ends of the shock absorbing spring are respectively against the end of the spring mounting column 43 and the limit plate 26.

[0025] The shock absorbing spring is in a compressed state, which can give the top of the shock absorbing bracket a force close to the limit plate, or give the caster a downward force, so that the caster can move close to the ground. When moving to an uneven ground, the caster is affected by the ground and exerts force on the front end of the caster bracket, and the shock absorbing spring acts on the rear end of the caster bracket, and the two form a seesaw structure, and the shock is absorbed by the swinging movement of the caster bracket, and the shock absorbing plate rotates with the caster bracket, and the limit plate rotates with the support plate and the partition plate, which can avoid interference with the shock absorption work.

[0026] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
