Description

Technical Field

[0001] This utility model relates to the field of conveying equipment, and in particular to casters, conveying machinery and cargo conveying systems. Background Technology

[0002] A swivel wheel is a device that can rotate horizontally 360°. It is widely used in various applications such as handcarts, suitcases, and logistics transportation.

[0003] As shown in the patent document with application publication number CN110834494A, the rollers of a conventional caster wheel are directly connected to the wheel seat via bearings or the like.

[0004] Bullseye slides are devices used to facilitate the movement of goods. As shown in the patent document with authorization announcement number CN219669269U, bullseye slides typically use bullseye bearings to support the goods.

[0005] It is feasible to use casters instead of bullseye bearings in bullseye slides. However, when conventional casters are used on bullseye slides, there will be a large gap between the casters, which can cause goods to get stuck in the gaps, especially for soft-packaged goods. Utility Model Content

[0006] The purpose of this utility model is to solve the above-mentioned problems existing in the prior art and to provide a universal wheel, a conveying device and a cargo conveying system.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] The omnidirectional wheel includes a base, on which a wheel seat is rotatably disposed relative to the base, and a roller is disposed on the wheel seat. The axis of the roller is perpendicular to the axis of rotation around which the wheel seat rotates. A baffle with an outer arc shape is disposed on the wheel seat, and the roller passes through the baffle.

[0009] Preferably, the base includes a base and a connecting plate, and a set of connecting holes are provided on the portion of the connecting plate extending to the outside of the base.

[0010] Preferably, the edge of the baffle is notched, and during the rotation of the wheel seat, the notch on the baffle can be rotated to correspond to the position of the connecting hole in the extension direction of the rotation axis.

[0011] Preferably, the center of a set of the connecting holes is located on a circle concentric with the axis of rotation.

[0012] Preferably, the notches are two in number and are symmetrically distributed on both sides of the roller.

[0013] A conveying device, comprising a base frame and a set of casters mounted on the base frame, characterized in that: the casters include a base, a wheel seat is rotatably mounted on the base, a roller is mounted on the wheel seat, the axis of the roller is perpendicular to the axis of rotation of the wheel seat when it rotates, and a baffle with an outer arc shape is mounted on the wheel seat, through which the roller passes.

[0014] Preferably, the upper cover of the base frame is provided with a circular hole that matches the baffle on each of the wheel seats.

[0015] Preferably, at least one side of the chassis is provided with a passage controller, the passage controller including a control block that can switch between a blocking state and a passage state. In the blocking state, the control block protrudes from the top of the chassis; in the passage state, the control block does not protrude from the top of the chassis.

[0016] Preferably, the upper cover of the base frame has an operation hole for operating the control block to switch states.

[0027] The purpose, advantages, and features of this utility model will be illustrated and explained through the following non-limiting description of preferred embodiments. These embodiments are merely typical examples of applying the technical solutions of this utility model, and all technical solutions formed by equivalent substitutions or equivalent transformations fall within the scope of protection claimed by this utility model.

[0029] Example 1

[0030] The universal wheel B disclosed in this utility model will be described below with reference to the accompanying drawings, as shown in the attached drawings. Figure 1 As shown, it includes a base 100, on which a wheel seat 200 is rotatably disposed relative to the base 100, and a roller 300 is disposed on the wheel seat 200. The axis of the roller 300 is perpendicular to the axis of rotation around which the wheel seat 200 rotates. A baffle 210 with an outer arc shape is disposed on the wheel seat 200, and the roller 300 passes through the baffle 210.

[0031] Details are attached. Figure 1 Appendix Figure 2 As shown, the base 100 includes a base 110 and a connecting plate 120. The shape of the base 110 can be designed as needed. In this embodiment, the base 110 is cylindrical, and the connecting plate 120 is a rectangular plate. The connecting plate 120 has a portion extending outside the base 110, and a set of connecting holes 121 are formed on the portion of the connecting plate 120 extending outside the base 110. The number of connecting holes 121 can be designed as needed, preferably four, and they are distributed in a square on the outer periphery of the base 110. The centers of the four connecting holes 121 are located on a circle concentric with the axis of rotation.

[0032] As attached Figure 2 As shown, the wheel seat 200 is rotatably mounted on the base 110 via a bearing. The baffle 210 is located above the axis of the roller 300. The baffle is provided with a mounting opening 212 for the roller 300 to pass through. The mounting opening extends inward from the edge of the baffle by a certain distance. At the same time, the bottom of the baffle is provided with mounting plates located on both sides of the mounting opening. The roller 300 is mounted between the two mounting plates.

[0033] The edge of the baffle 210 has a notch 211, which is arc-shaped, but can also be other feasible shapes. During the rotation of the wheel seat 200, the notch 211 on the baffle 210 can rotate to correspond to the position of the connecting hole 121 in the extension direction of the rotation axis. At this time, the bolts or screws at the connecting hole 121 can be tightened or loosened directly through the notch 211 of the baffle 210 using tools such as a screwdriver or power screwdriver, thereby realizing the assembly and disassembly of the omnidirectional wheel B.

[0034] Furthermore, to facilitate manual handling of the caster B, there are two notches 211 symmetrically distributed on both sides of the caster 300. When one notch 211 corresponds to a connecting hole 121, the other notch 211 can correspond to the position of another connecting block.

[0035] Example 2

[0036] This embodiment discloses a conveying device, as shown in the attached figure. Figure 3 As shown, it includes a base frame A and a set of casters B mounted on the base frame A. The casters B include a base 100, on which a wheel seat 200 is rotatably mounted. A roller 300 is mounted on the wheel seat 200. The axis of the roller 300 is perpendicular to the axis of rotation around which the wheel seat 200 rotates. A baffle 210 with an arc-shaped outer contour is mounted on the wheel seat 200, and the roller 300 passes through the baffle 210.

[0037] The base frame A includes a frame and multiple rows of mounting rods mounted on the frame. Each row of mounting rods is equipped with a row of casters B. The frame is also equipped with a top cover A3. The top cover A3 has a circular hole A31 that matches the baffle 210 on each caster seat 200. The baffle 210 of each caster B is located in one of the circular holes A31, and the top surface of the baffle 210 is flush with the top surface of the top cover A3, or it can be slightly higher or lower. The baffle 210 can rotate within the circular hole A31, so that the top cover A3 and the baffle 210 can effectively cover the gap between the casters B, minimizing the risk of jamming.

[0038] Furthermore, in practical applications, one or more sides of the conveyor need to be able to control whether the goods can slide and pass through. Correspondingly, see the attached... Figure 3 As shown, a passage controller C is provided on at least one side of the base frame A. The passage controller C includes a control block C1 that can switch between a blocking state and a passage state. In the blocking state, the control block C1 protrudes from the top of the base frame A; in the passage state, the control block C1 does not protrude from the top of the base frame A.

[0039] As attached Figure 4 Appendix Figure 5 As shown, the access controller C includes a fixed base C2, which is fixed to the base frame A. The fixed base C2 includes a bottom connecting plate C21 and vertical plates C22 that are perpendicularly connected to the bottom connecting plate C21 and parallel to each other. A horizontal shaft C23 is provided between the two vertical plates C22. The control block C1 is rotatably and linearly movable relative to the horizontal shaft C23. The control block C1 is a cuboid. Specifically, a strip-shaped hole C11 is formed on the control block C1. The horizontal shaft C23 passes through the strip-shaped hole C11. The extension direction of the strip-shaped hole C11 forms an acute angle with the length direction of the control block C1. When the control block C1 is in an obstructed state, the length direction of the control block C1 extends vertically and the control block C1 is located on the top surface of the bottom connecting plate C21. The strip-shaped hole C11 is located in the lower middle position of the control block C1 and tilts to the upper right. When the control block C1 is in the passage state, the length of the control block C1 extends horizontally, and the control block C1 lies on the bottom connecting plate C21 or the pad on the bottom connecting plate C21. At this time, the strip hole C11 is tilted towards the upper left corner of the control block C1.

[0040] Furthermore, at least one side of the control block C1 has an operating groove C12. The operating groove C12 and the strip hole C11 are located on the same long side of the control block C1. Correspondingly, the vertical plate C22 on the side corresponding to the operating groove C12 is provided with an operating opening C24, which is arc-shaped. When the control block C1 is in the passage state, the operating groove C12 and the operating opening C24 are directly opposite each other, so that the operator's thumb can be used to grip the operating groove C12 through the operating opening C24, thereby facilitating the switching of the state of the control block C1. Of course, the operating groove C12 is not necessary and can be omitted.

[0041] As attached Figure 3As shown, in order to facilitate the operation of the control block C1, an operation hole A32 for operating the control block C1 to switch states is formed on the upper cover of the base frame A. The operation hole A32 includes a rectangular hole corresponding to the operation block and a finger avoidance hole connected to the side of the rectangular hole. The operator's fingers can be inserted into the operation groove C12 through the finger avoidance hole to perform the operation.
