The present application claims the priority of the Chinese patent application filed on Jun. 21, 2017, the number of which is incorporated herein by reference. In this article.

Technical field

The present invention relates to a container, and in particular to a movable unit such as a super display unit.

Background technique

As a light container, the Super Display Unit (RDU) is used for shopping mall display of retail products, simple storage and picking and transportation of some dried fruits and vegetables. The general length and width of these boxes are 800mm*600mm, and the height is generally not More than 1000mm. A considerable portion of these RDUs have wheels, and the wheel has a wheel diameter of 3 inches and 4 inches. The RDU with wheels can be moved quickly in a local area, which facilitates the handling of the cabinet. Some malls or storage units have both RDUs and RDUs without wheels, and they use pick-up forklifts to carry these boxes—whether they are wheelless or wheeled RDUs.

In general, a forklift with a fixed tines has a minimum outer width of about 540 mm. When the RDU has wheels, this width will interfere with the wheel area. When the box requires forklift handling When the wheel body is generally in a braking state, when the forklift forks enter, there is a risk of the wheel body being damaged, as shown in FIG. 2 .

As shown in FIG. 1 , the commercial super display unit (RDU) has a base 2 and a side panel 3 , and the side panel 3 is connected to the base 2 . A small door 4 is provided on one or more of the side panels 3. A forklift fork groove 21 is provided in the middle of the base 2. The forklift tines 21 are used for the fork teeth 5 of the forklift to pass through, as shown in Figures 2-3. At present, the length and width dimensions of most commercial super display units are usually about 800mm*600mm. The fork fork groove has a width of not less than 540 mm.

A set of wheels 1 is mounted on the base 2 on each side of the forklift tines 21 of the forklift. The wheels 1 may all be universal wheels, or one of the wheels may be a normal roller, and the other wheel may be a universal wheel. Here, two sets of universal wheels will be described as an example.

As shown in FIG. 4, the universal wheel 1 is composed of a mounting base 11, a bracket 12, a steering positioning disk 14 (also referred to as a universal brake pad), a steering brake member 13, and a wheel body 15. The mounting base 11, the bracket 12, the steering locating disc 14 (also referred to as a universal brake pad), and the steering brake member 13 constitute a steering mechanism. The steering locating disc 14 is relatively fixed to the mounting base 11, and the steering brake member 13 is relatively rotatably fixed to the bracket 12. The bracket 12 is rotatable relative to the mounting base 11. Here, in addition to the steering locating disc 14 and the steering brake member 12, the mounting base 11 and bracket 12 and associated structures and the like can employ any suitable structure known or to be developed in the art.

The steering locating disc 14 and the steering brake member 12 may have various forms as long as a positioning structure is provided on the steering locating disc 14, and a limiting structure is provided on the steering brake member 12, and after the bracket 12 is rotated by a predetermined angle, the positioning structure And the limit structure can cooperate to achieve the braking state.

5-6 are schematic views showing the structure of the steering locating disc 14 and the steering brake member 12 according to the first embodiment of the present invention. As shown in FIGS. 5-6, the steering locating disc 14 is a disc-shaped member, and its outer edge is provided with two diametrically

opposed positioning grooves

141 and 142 at 12 o'clock and 6 o'clock in the direction indicated by the steering locating disc 14. .

One end of the steering brake member 13 is rotatably coupled to the bracket 12. The other end of the steering brake member 13 has a positioning projection 131. The positioning protrusion 131 can protrude into the positioning groove 141 or the positioning groove 142 of the steering positioning disk 14 when the universal wheel 1 is in the locked state. Thus, the steering function of the universal wheel 1 is locked when the wheel body 15 is rotated only to the two angular directions. Therefore, when the universal wheel 1 is in the locked state in time, the fork teeth of the forklift 3 can also be allowed to enter the foot space of the RDU without damaging the universal wheel 1.

It should be understood that, in this embodiment, the positioning groove on the steering positioning plate 14 can also be changed into a positioning protrusion, and the positioning protrusion of the steering brake member 13 can be correspondingly changed into a positioning groove, and the steering brake effect can also be achieved. .

7-8 are views showing the structure of the steering locating disc 14 and the steering brake member 12 according to the second embodiment of the present invention. As shown in Figures 5-6, the steering locating disc 14 is a disc-shaped member which is composed of two segments having the same center and different diameters. The faces 149 and 150 formed by the intersection of the two segments are the positioning structures. Preferably, as shown in FIG. 5-6, the two sector segments have the same central angle, that is, the two segments are semicircular.

One end of the steering brake member 13 is rotatably coupled to the bracket 12. The other end of the steering brake member 13 has a positioning projection 131. The positioning projection 131 can project into the smaller diameter segment of the steering locating disc 14 when the universal wheel 1 is in the locked state. Thus, the steering function of the universal wheel 1 is locked when the wheel body 15 is only rotated to this

face

149 or 150. Therefore, when the universal wheel 1 is in the locked state in time, the fork teeth of the forklift 3 can also be allowed to enter the foot space of the RDU without damaging the universal wheel 1.

9-10 are schematic views showing the structure of a steering locating disc 14 and a steering brake member 12 according to a third embodiment of the present invention. The difference between the embodiment and the embodiment shown in FIG. 5-6 is that the steering positioning plate 14 has a plurality of positioning grooves 144 148 148 which are evenly distributed on the opposite sides of the wheel body 15 to avoid the fork teeth of the forklift 3. The rest are the same and will not be described in detail here.

When preparing to carry the commercial super display unit of the present invention, by means of the above-described universal brake structure, even if the universal wheel 1 is locked, it can be allowed to rotate to the vertical angle of the wheel body shown in FIG. This space of the universal wheel 1 avoiding allows the forks of the forklift 3 to enter without damaging the universal wheel 1. Specifically, when the fork teeth of the forklift 3 enter the casing, the fork teeth will interfere with and collide with one of the universal wheels 1 , and although the universal wheel 1 is in the braking state, the wheels cannot roll, but they still have a local angle. The ability to turn so that the wheel body can be rotated a certain angle under the push of the tines and avoid a space to allow the tines to enter.

It should be noted that other configurations of the universal wheel of the present application, such as the roller locking mechanism, may employ any suitable mechanism as present and will not be described in detail herein.

In addition, it should be understood that the technical solution of the present application can also be applied to other movable units such as a tray, a cardboard box, and the like, which have a base and a forklift fork groove and are mounted with a universal wheel. These movable units typically have a length to width dimension of about 800 mm * 600 mm, and the width of the forklift tines on the forklift is typically not less than 540 mm.

The preferred embodiments of the present invention have been described in detail hereinabove, but it is understood that the aspects of the embodiments can be modified, and the various aspects, features, and concepts of the various patents, applications, and publications can be used to provide additional embodiments.

These and other changes can be made to the embodiments in light of the above detailed description. In general, the terms used in the claims are not to be construed as limited to the specific embodiments disclosed in the description and the claims. range.
