Description

Technical Field

[0001] The utility model relates to the field of luggage cases, in particular to a connecting piece. Background Art

[0002] With the development of the economy, people are paying more and more attention to their spiritual life. Traveling far away with a suitcase is a good choice. Suitcases are an indispensable companion during travel. Choosing the right suitcase can greatly enhance the travel experience.

[0003] A suitcase typically has four universal wheels fixedly mounted on its underside for users to tow. These wheels are typically fixedly connected to the suitcase body via wheel mounts. Existing universal wheels are typically mounted on the outside of the suitcase's outer shell. The weight of the suitcase and its contents is applied to the connection between the outer shell and the universal wheels, which undoubtedly creates excessive shear forces at the connection. Furthermore, to increase volume, the outer shell is typically only a thin layer, so the connection is not very strong and is therefore prone to damage.

[0004] In view of this, in order to overcome the above technical problems, the present invention designs a connecting piece to solve the above technical problems. Utility Model Content

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the devices or components referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention; the terms "first", "second", and "third" are only used for descriptive purposes and should not be understood as indicating or implying relative importance; in addition, unless otherwise expressly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, an indirect connection through an intermediate medium, or it can be internal communication between two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. In response to the problems existing in the prior art, the following solutions are proposed:

[0027] Example 1, as Figure 1-4As shown, four universal wheels are installed at the four corners of the lower end of the box body. The universal wheels are fixed to the box body through the wheel seat 1. A connecting pipe 3 is fixedly installed on the side of the box body. A connection is provided between the connecting pipe 3 and the wheel seat 1 through a transfer seat 2. One end of the transfer seat 2 is a clamping end 21. The transfer seat 2 is clamped to the connecting pipe 3 through the clamping end 21. The other end of the transfer seat 2 is a fitting end 22. The fitting end 22 and the wheel seat 1 fit together. The fitting end 22 is clamped into the gap between the box body and the wheel seat 1. The above steps realize the transfer between the connecting pipe 3 and the wheel seat 1, so that part of the supporting force applied by the wheel seat 1 to the outer shell of the box body is transferred to the connecting pipe 3.

[0028] The connecting tube 3 is the tie rod fixing rod, which connects and secures the tie rod to the housing. The clamping end 21 is embedded in the lower end of the tie rod fixing rod and clamps thereto. The fitting end 22 fits against the arc surface of the wheel seat 1 and is embedded in the groove between the housing and the wheel seat 1 and clamps thereto. The clamping end 21 is provided with a brake pipe groove 211, which is directly opposite the brake hole on the wheel seat 1 and is used to accommodate the outer tube of the brake cable. The clamping end 21 thus achieves the connection between the tie rod fixing rod and the wheel seat 1.

[0029] The connection between the wheel seat 1 of the universal wheel and the box body is changed from the outer shell of the box body to the pull rod fixing rod, and the force-bearing position is changed from the weak outer shell body to the stronger pull rod fixing rod, thereby increasing the strength of the connection between the wheel seat 1 and the box body, avoiding damage to the connection point between the box body and the wheel seat 1 due to the excessive weight of the box body and its contents.

[0030] Example 2, as Figure 1-4 As shown, the clamping end 21 of the adapter 2 is provided with a No. 1 screw hole 212, which is fixedly connected to the tie rod fixing rod by screws, thereby further reinforcing the connection between the clamping end 21 and the tie rod fixing rod. The clamping end 21 of the adapter 2 is provided with a No. 2 screw hole 213, which is directly opposite the connecting screw hole on the wheel seat 1. The No. 2 screw hole 213 and the wheel seat 1 are fixedly connected by screws, thereby further reinforcing the connection between the adapter 2 and the wheel seat 1. At the same time, since the wheel seat 1 itself is provided with a plurality of connecting screw holes for connecting to the box body, it is not necessary to open additional screw holes on the wheel seat 1 to complete the reinforcement with the adapter 2, thereby reducing the production process of the wheel seat 1 and saving the manufacturing cost of the wheel seat 1.

[0031] Example 3, as Figure 5-8As shown, the connecting tube 3 is a decorative strip that is fixedly mounted on the side of the box body and serves to strengthen and decorate the side of the box body. The clamping end 21 of the adapter 2 is provided with a clamping edge. The clamping edge is provided with several layers, and the plurality of layers of clamping edges have side grooves between each other. The clamping edge is clamped with the decorative strip by the clamping edge. As a result, the clamping edge has a certain elastic change, and the clamping edge can better clamp with the decorative strip through elastic deformation. The fitting end 22 of the adapter 2 fits with the wheel seat 1, and the fitting end 22 of the adapter 2 is embedded in the gap between the wheel seat and the box body and clamped.

[0032] The wheel seat 1 is connected to the decorative strip via the adapter 22 , which not only strengthens the connection between the wheel seat 1 and the box, but also beautifies the connection between the decorative strip and the wheel seat 1 .

[0033] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
