Description

Technical Field

[0001] This utility model relates to a wear-resistant bag with detachable wheels. Background Technology

[0002] Patent CN211075405U discloses a detachable bag wheel. This bag wheel is installed and fixed to the bottom of the bag via a quick-release plug. However, this type of bag has the following disadvantages: the bag itself is made of vacuum forming material, which is not reliable enough. Once the connection part on the bag used to connect the roller is damaged, even if the roller is detachable, it is difficult to avoid the scrapping of the entire bag. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a wear-resistant bag with detachable wheels. The bottom is equipped with a detachable protective plate, and the rollers are installed and fixed on the protective plate. The rollers are also detachable, which can prevent the entire bag from being scrapped due to damage to the connection of the rollers on the bag.

[0004] The technical solution of this utility model is: a wear-resistant bag with detachable wheels, including a bag, a protective plate set at the bottom of the bag, and four sets of rollers fixed on the protective plate; The bottom surface of the guard plate is provided with a positioning platform at each of the four corners. The top of the wheel frame of the four sets of rollers is provided with a positioning groove corresponding to the positioning platform. Each wheel frame is fastened on the corresponding positioning platform. The outer periphery of the positioning platform and the wheel frame are also provided with multiple corresponding first screw holes. Multiple first bolts are screwed into the top surface of the guard plate to fix the wheel frame and the guard plate together. The protective plate has process grooves on its four sides, a first fixing hole in the middle of the protective plate, and multiple second fixing holes at the four corners of the protective plate. Process holes are also provided on the protective plate on both sides of the first fixing hole. The protective plate is fixed to the bottom of the bag by multiple second bolts.

[0005] Specifically, the protective plate is a one-piece molded aluminum alloy structure.

[0006] Furthermore, the bottom of the bag is provided with a fixing groove for a corresponding protective plate, the protective plate is fixed in the fixing groove, and the bottom surface of the protective plate is flush with the bottom surface of the bag.

[0007] Furthermore, the first screw hole on the protective plate is a countersunk hole.

[0008] Specifically, each set of rollers consists of double rows of rollers.

[0009] Specifically, the wheel frame is a swivel wheel frame.

[0010] Specifically, the bag is a trolley bag.

[0011] The beneficial effects of this utility model are as follows: In this utility model, the positioning platform facilitates the installation and fixation of the wheel frame and improves the reliability of the connection between the wheel frame and the protective plate; the wheel frame is a detachable structure, and when a set of rollers is severely worn, the entire set of rollers can be replaced by disassembling the wheel frame; the main purpose of setting up each process groove and process hole is to reduce the weight of the protective plate and save the raw materials for manufacturing the protective plate. The protective plate is fixed to the bottom of the bag, which on the one hand provides protection for the bottom of the bag and greatly improves the strength and reliability of the bottom of the bag; on the other hand, each set of rollers is fixed to the protective plate, and since the protective plate is more robust than the vacuum-formed bag, it can effectively improve the reliability of the connection between each set of rollers; and the protective plate is also a replaceable structure, which on the one hand facilitates the disassembly and assembly of each set of rollers, and on the other hand can prevent the entire bag from being scrapped due to damage to the connection between the wheel frame on the bag.

[0014] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0015] Combination Figure 1-3 As shown, a wear-resistant bag with detachable wheels includes a bag 1, a protective plate 2 set at the bottom of the bag 1, and four sets of rollers 3 fixed on the protective plate 2. The bottom surface of the guard plate 2 is provided with a positioning platform 4 at each of the four corners. The top of the wheel frame of the four sets of rollers 3 is provided with a positioning groove corresponding to the positioning platform 4. Each wheel frame is fastened on the corresponding positioning platform 4. The outer periphery of the positioning platform 4 and the wheel frame are also provided with multiple corresponding first screw holes 5. Multiple first bolts are screwed on the top surface of the guard plate 2 to fix the wheel frame and the guard plate 2 together. In the above structure, the positioning platform 4 facilitates the installation and fixation of the wheel frame and improves the reliability of the connection between the wheel frame and the guard plate 2; the wheel frame is a detachable structure, and when a set of rollers 3 is severely worn, the entire set of rollers 3 can be replaced by disassembling the wheel frame; The protective plate 2 has process grooves 8 on its four sides, a first fixing hole 6 in the middle of the protective plate 2, and multiple second fixing holes 7 at the four corners of the protective plate 2. Process holes 9 are also provided on the protective plate 2 on both sides of the first fixing hole 6. The protective plate 2 is fixed to the bottom of the bag 1 by multiple second bolts. In the above structure, the main purpose of setting each process groove 8 and process hole 9 is to reduce the weight of the protective plate 2 and save the raw materials for manufacturing the protective plate 2. The protective plate 2 is fixed to the bottom of the bag 1, which on the one hand can provide protection for the bottom of the bag 1 and greatly improve the strength and reliability of the bottom of the bag 1. On the other hand, each set of rollers 3 is fixed on the protective plate 2. Since the protective plate 2 is more robust than the vacuum-formed bag 1, it can effectively improve the reliability of the connection of each set of rollers 3. Moreover, the protective plate 2 is also a replaceable structure, which facilitates the disassembly and assembly of each set of rollers 3 and also avoids the scrapping of the entire bag 1 due to damage to the wheel frame connection on the bag 1.

[0016] In another embodiment, the protective plate 2 is a one-piece aluminum alloy structure, which has the advantages of being lightweight, strong, and corrosion resistant.

[0017] In another embodiment, such as Figure 3 As shown, the bottom of the bag 1 is provided with a fixing groove corresponding to the protective plate 2. The protective plate 2 is fixed in the fixing groove, and the bottom surface of the protective plate 2 is flush with the bottom surface of the bag 1 to avoid the protruding protective plate 2 affecting the overall appearance of the bag 1.

[0018] In another embodiment, the first screw hole 5 on the guard plate 2 is a countersunk hole to avoid the protruding cap end of the first bolt affecting the assembly of the guard plate 2.

[0019] In another embodiment, combined Figure 1 and Figure 3 As shown, each group of rollers 3 consists of double-row rollers.

[0020] In another embodiment, the wheel frame is a swivel wheel frame.

[0021] In another embodiment, such as Figure 3 As shown, the bag 1 is a trolley bag 1.
