[0002] Metal buckles are widely used in a variety of applications, including luggage, clothing, footwear, and leather goods, as connecting, securing, or decorative components. They are often found on handles, shoulder straps, and side straps of bags, providing connection, securing, and decorative features. For example, in outdoor products like mountaineering and travel bags, metal square buckles are often used to connect the straps to the backpack body, ensuring stability and durability.

[0003] Existing products use metal buckles for sleeves. During use, the sleeves vibrate and make noise, affecting the user experience. Furthermore, due to the shaking of the sleeves, the sleeves are prone to wear and tear due to friction with the metal buckle over long-term use. This not only causes scratches and paint peeling, but also reduces the lifespan of the metal buckle. Therefore, how to provide a connecting ring and luggage that reduces noise generation by reducing sleeve shaking and reduces contact wear between the sleeves and the metal buckle during use, thereby extending the service life, is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of the utility model is to provide a connecting ring and a bag, which solves the technical problem that existing products using metal ring buckles with sleeves will shake and make noise during use, affecting the user experience. In addition, due to the shaking of the sleeve, the sleeve is easily worn by friction with the metal ring buckle, which reduces the service life of the metal ring buckle.

DETAILED DESCRIPTION

[0026] The following will be combined with the 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.

[0027] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0028] The utility model provides a connecting ring and a bag, wherein the elastic force of the elastic member 12 limits the movement of the connecting roller 20. If the connecting roller 20 rotates, it will be subjected to a large friction force, which can reduce the shaking of the connecting roller 20 and reduce noise generation.

[0029] Please refer to Figures 1 to 5 The connecting ring provided by the utility model includes a connecting ring body 10 and a connecting roller 20; bosses 11 are provided at both ends of the connecting ring body 10, and the bosses 11 are provided with grooves 1121. An elastic member 12 is sleeved on the grooves 1121, and a mounting column 13 is provided between the two bosses 11. The two ends of the mounting column 13 are respectively connected to the two bosses 11, and the connecting ring body 10 and the mounting column 13 form an annular structure; the connecting roller 20 is sleeved on the mounting column 13. When the connecting roller 20 is sleeved on the mounting column 13, the elastic member 12 enters the connecting roller 20, and the elastic member 12 is pressed against the connecting roller 20 under the action of elastic force to limit the movement of the connecting roller 20.

[0030] The connecting ring body 10 and the mounting post 13 form an annular structure. When in use, the connecting roller 20 is sleeved on the mounting post 13, and the bosses 11 at both ends of the connecting ring partially extend into the interior of the connecting roller 20, so that the elastic member 12 enters the connecting roller 20. The elastic member 12 is squeezed under the action of the boss 11 and the inner wall of the connecting roller 20, so that the elastic member 12 is pressed against the connecting roller 20 under the action of elastic force to limit the movement of the connecting roller 20. If the connecting roller 20 rotates, it will be subjected to a greater friction force, that is, there is a damping feeling when the connecting roller 20 rotates, which can reduce the shaking of the connecting roller 20 and reduce noise generation. At the same time, it reduces the contact wear between the connecting roller 20 and the connecting ring body 10 during use, thereby improving the service life.

[0031] In this embodiment, the connecting ring body 10 is roughly U-shaped, and the connecting ring body 10 and the mounting post 13 roughly form a rectangular structure. However, the shape and structure of the connecting ring body 10 are not limited to this. The connecting ring body 10 can also be arc-shaped, in which case the connecting ring body 10 and the mounting post 13 roughly form a semicircular structure. The bending portion of the connecting ring body 10 has a smooth transition, that is, the bending portion of the connecting ring body 10 has rounded corners. Such a setting can enhance durability and safety. The rounded corner treatment can reduce stress concentration and increase the strength and durability of the connecting ring body 10. Secondly, it can reduce wear and collision during use, installation, disassembly and transportation, reducing maintenance and replacement costs. Thirdly, the rounded corner treatment can make the appearance of the connecting ring body 10 smoother and more comfortable, which can improve the aesthetics.

[0032] In addition, the two ends of the mounting column 13 are detachably connected to the two bosses 11, for example, the two ends of the mounting column 13 are respectively clamped with the two bosses 11. Specifically, the boss 11 can be provided with a clamping hole, and the clamping hole is adapted to the mounting column 13. The two ends of the mounting column 13 are respectively connected to the boss 11 through the clamping holes on the two bosses 11, which is convenient for installation. However, the detachable connection method between the mounting column 13 and the two bosses 11 is not limited to this.

[0033] Please refer to Figures 1 to 5The connecting roller 20 is provided with a through hole 21 along the axial direction. The through hole 21 is located in the center of the connecting roller 20. When the connecting roller 20 is sleeved on the mounting post 13, the elastic member 12 enters the through hole 21 and abuts against the inner wall of the connecting roller 20. When in use, the connecting roller 20 is sleeved on the mounting post 13. The bosses 11 at both ends of the connecting ring extend into the interior of the connecting roller 20 through the two through holes 21. The elastic members 12 of the two bosses 11 enter the interior of the connecting roller 20 through the through holes 21. The elastic members 12 are squeezed by the bosses 11 and the inner wall of the connecting roller 20. As a result, the elastic member 12 abuts against the inner wall of the connecting roller 20 under the action of the elastic force. The movement of the connecting roller 20 is restricted. If the connecting roller 20 rotates, it will be subjected to greater friction. This can reduce the shaking of the connecting roller 20 and reduce noise generation. At the same time, it reduces the contact wear between the connecting roller 20 and the connecting ring body 10 during use, thereby improving the service life.

[0034] Please refer to Figures 1 to 6 , limiting flanges 22 are provided at both ends of the connecting roller 20. The limiting flanges 22 are used to prevent the connecting belt 30 from directly contacting the connecting ring body 10. The limiting flanges 22 are located at both ends of the connecting roller 20. When the connecting ring is in use, the connecting belt 30 is wound around the connecting roller 20, and the connecting belt 30 is located between the two limiting flanges 22. The two limiting flanges 22 limit the displacement of the connecting belt 30 along the axial direction of the connecting roller 20, preventing the connecting belt 30 from contacting the connecting ring body 10 and preventing friction between the connecting belt 30 and the connecting ring body 10. Since the connecting ring body 10 is generally a metal part, this configuration prevents paint peeling caused by long-term friction between the metal part and the connecting belt 30, and avoids corrosion of the metal part.

[0035] Please refer to Figures 1 to 5 The limiting flange 22 is annular. With this configuration, the annular limiting flange 22 can fully block the contact between the connecting belt 30 and the connecting ring body 10, effectively avoiding friction between the connecting belt 30 and the connecting ring body 10.

[0036] Please refer to Figures 1 to 5 The boss 11 includes a connecting portion 111 and a limiting portion 112. The connecting portion 111 is fixed to the connecting ring body 10. The limiting portion 112 is connected to the connecting portion 111. The groove 1121 is provided in the limiting portion 112. The groove 1121 is located at the connection between the limiting portion 112 and the connecting portion 111.

[0037] Please refer to Figures 1 to 5The connecting portion 111 is in the shape of a truncated cone, and the size of the side where the connecting portion 111 is connected to the connecting ring body 10 is larger than the size of the other side of the connecting portion 111, that is, the size of the connecting portion 111 gradually decreases from the side close to the connecting ring body 10 to the side close to the limiting portion 112. The limiting portion 112 is roughly cylindrical, and the size of the limiting portion 112 is the same as the size of the side of the connecting portion 111 close to the limiting portion 112.

[0038] With this arrangement, when the connecting roller 20 is mounted on the mounting post 13, the bosses 11 at both ends of the connecting ring can easily extend into the interior of the connecting roller 20 through the two through-holes 21, and the elastic members 12 of the two bosses 11 can easily pass through the through-holes 21 and into the interior of the connecting roller 20. After the connecting roller 20 is installed in place, the two ends of the connecting roller 20 respectively abut against the two ends of the connecting ring body 10, thereby limiting the movement of the connecting roller 20 in the axial direction. Combined with the elastic member 12 restraining the connecting roller 20 under the action of the elastic force, it can effectively reduce the shaking of the connecting roller 20, reduce noise generation, and improve the user experience.

[0039] Preferably, the elastic member 12 is an elastic rubber ring, which is sleeved through its center hole into the groove 1121 of the boss 11. The connecting portions 111 and the limiting portions 112 on either side of the groove 1121 limit the elastic rubber ring. After the connecting roller 20 is sleeved onto the mounting post 13, the elastic rubber ring is squeezed by the boss 11 and the inner wall of the connecting roller 20. The elastic force of the elastic rubber ring abuts against the inner wall of the connecting roller 20, thereby restricting the movement of the connecting roller 20. If the connecting roller 20 rotates, it will be subject to greater friction, which can reduce the shaking of the connecting roller 20 and reduce noise generation.

[0040] Please refer to Figures 1 to 5 The groove 1121 is an annular groove, which is used to cooperate with the elastic rubber ring. With this arrangement, the inner wall of the connecting roller 20 contacts the elastic rubber ring evenly. When the elastic rubber ring is squeezed, the inner wall of the connecting roller 20 is evenly stressed. Under the joint action of the two elastic rubber rings inside the connecting roller 20, the shaking of the connecting roller 20 is effectively reduced.

[0041] The mounting post 13 is detachably connected to both ends of the connecting ring body 10. When assembling the connecting ring, first remove the mounting post 13 from the bosses 11 at both ends of the connecting ring body 10, and then install the two elastic rubber rings in the grooves 1121 of the two bosses 11 respectively. The connecting roller 20 is sleeved on the outside of the mounting post 13 through the through hole 21, and the bosses 11 at both ends of the connecting ring extend into the interior of the connecting roller 20 through the two through holes 21. The two elastic rubber rings enter the interior of the connecting roller 20 through the through holes 21. The elastic rubber rings are squeezed under the action of the boss 11 and the inner wall of the connecting roller 20, so that the elastic rubber rings are held against the inner wall of the connecting roller 20 under the action of elastic force, and the movement of the connecting roller 20 is restricted. If the connecting roller 20 rotates, it will be subjected to greater friction, which can reduce the shaking of the connecting roller 20 and reduce noise generation. At the same time, it reduces the contact wear between the connecting roller 20 and the connecting ring body 10 during use, thereby improving service life.

[0042] Please refer to Figure 6 When the connecting ring provided by the embodiment of the present invention is used, the two connecting belts 30 are respectively connected to the connecting ring body 10 and the connecting roller 20. Under the restriction of the two limiting flanges 22 at both ends of the connecting roller 20, the connecting belt 30 will not contact the connecting ring body 10, thereby blocking the friction between the connecting belt 30 and the connecting ring body 10. This arrangement avoids the paint peeling caused by long-term friction between the connecting ring body 10 and the connecting belt 30, and avoids corrosion of the connecting ring body 10.

[0043] In addition to the connecting rings disclosed in the above embodiments, the present invention also provides a bag including the connecting rings. The structures of the other parts of the bag can refer to the existing technology and will not be described in detail herein. The bag can produce the same technical effects as the connecting rings.

[0044] Optionally, the connecting ring body 10 can be processed by cold working method, which is suitable for metal rods with smaller diameter and weaker strength. The specific steps include:

[0045] 1. Prepare equipment: Use equipment such as pipe bending machines and plate shearing machines, and select different equipment for processing according to needs.

[0046] 2. Clamp the metal rod: Clamp the metal rod into the pipe bender and adjust the bending angle.

[0047] 3. Multiple bending: For iron bars that need to be bent multiple times, the metal bar can be rotated appropriately after each bending to achieve the desired bending angle.

[0048] When bending perpendicular to the straight direction of the metal rod is required, the metal rod can be tilted 45 degrees before bending.

[0049] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0050] This article uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the present invention.
