Description

Technical Field

[0001] This utility model relates to the field of handlebar grips, specifically to pull-out silicone rubber handlebar grips. Background Technology

[0002] Handlebar grips, as a key gripping component of vehicle handlebars, are widely used in vehicle control, including but not limited to bicycles, electric bikes, and motorcycles. Their technical aspect involves the intersection of materials science and ergonomics, requiring simultaneous performance requirements such as anti-slip properties, shock absorption, weather resistance, and long-term reliability. Silicone rubber, due to its excellent elasticity, resistance to high and low temperatures, and biocompatibility, has become the preferred material for handlebar grips.

[0003] Existing handlebar grips typically use a slip-on structure, securing them to the handlebar surface by wrapping or binding. The basic structure includes a silicone rubber body layer and a textured surface for improved grip. Some products incorporate reinforcing fibers or employ a two-color injection molding process to enhance structural strength. When using them, users must gradually push the grips into place from the end of the handlebar, allowing them to be secured through elastic deformation. Some models require auxiliary tools for proper positioning.

[0004] However, existing silicone rubber handlebar grips have significant drawbacks during installation. Due to the high elasticity and low surface friction coefficient of silicone rubber, traditional fitting methods require a large axial thrust to achieve the fit, and local twisting and jamming are prone to occur during the fitting process, resulting in low installation efficiency. Especially when there are limiting structures at the end of the handlebar (such as reducing diameter sections or threaded ends), conventional push-in installation can easily cause tearing of the inner wall of the handlebar grip or damage to the surface coating of the handlebar. In addition, the lack of guiding and positioning structures in the existing fitting methods makes it difficult to ensure quick positioning and connection between the handlebar grip and the handlebar, requiring repeated adjustments to achieve the ideal installation state, further reducing the ease of installation. Utility Model Content

[0005] The purpose of this invention is to address the above-mentioned deficiencies by providing a pull-out silicone rubber handlebar cover, thereby solving the technical problem in the background art of how to make the handlebar cover and handlebars easily connected and installed, so as to improve the installation efficiency of the handlebar cover.

[0006] The objective of this utility model is achieved through the following means:

[0007] A pull-out silicone rubber handlebar grip includes an elastic sleeve and a pull-out core rope. The pull-out core rope has interlocking buckle structures on both sides, extending along the length of the core rope. This allows the core rope to spirally encircle and form an axially extending support tube. The support tube has a through hole inside, and the elastic sleeve has a through-hole. The elastic sleeve is fitted onto the support tube through the through-hole, allowing the support tube to provide expansion support to the elastic sleeve's through-hole. One end of the support tube has a pull-out section, which extends through the through-hole to the other end of the support tube.

[0008] Furthermore, as described above, the outer surface of the elastic sleeve is provided with anti-slip textures. The anti-slip textures are arranged axially on the outer surface of the elastic sleeve. The anti-slip textures can be any one type of point, line, or surface, or any combination of two or three types.

[0009] By setting anti-slip textures along the axial direction on the outer surface of the elastic sleeve, and using different types or combinations of anti-slip textures such as dots, lines, or surfaces, the friction between the hand and the handlebar grip can be effectively increased, preventing the hand from slipping due to sweat during riding, thus improving riding safety and control. At the same time, it also helps to improve the problem of easy slippage during installation caused by the low surface friction coefficient of traditional handlebar grips, and assists the installation process to a certain extent.

[0010] Further as described above, the buckle structure includes a first buckle portion with an inward opening and a second buckle portion with an outward opening. The inner side of the first buckle portion is formed with a first buckle groove and a first buckle protrusion, and the outer side of the second buckle portion is formed with a second buckle groove for mating and fastening the first buckle protrusion and a second buckle protrusion for mating and fastening the first buckle groove.

[0011] This specific snap-fit ​​structure design allows the first and second snap-fit ​​parts to precisely match and engage as the pull-out core rope spirals and forms the support tube, providing a stable and reliable connection structure for the support tube and ensuring its structural integrity. This snap-fit ​​structure also enables the pull-out core rope to quickly and accurately form the support tube during installation and positioning, thus enhancing the support for the silicone elastic sleeve.

[0012] Furthermore, as described above, the interior of the first and second snap-fit ​​grooves is formed with tapered slopes.

[0013] The tapered slope design inside the first and second snap-fit ​​grooves guides and positions the snap-fit ​​structure during mating and engagement, making it easier and more accurate for the first and second snap-fit ​​protrusions to enter their corresponding grooves, further improving installation convenience and precision. Simultaneously, the tapered slope increases the stability of the connection after engagement, preventing loosening or detachment during use and resolving the issue of weak connections caused by localized twisting or jamming in traditional installation methods.

[0014] Furthermore, as described above, the pull-out core rope is continuously spirally wound to pair the first and second buckle parts, and then heat-sealed to form a hollow support tube.

[0015] The pull-out core rope is continuously spirally wound and heat-sealed to form a hollow support tube, giving the support tube good strength and stability, and providing reliable expansion support for the elastic sleeve. During installation, the structural characteristics of the support tube can avoid the local twisting and jamming problems caused by the high elasticity of silicone rubber in traditional sleeve methods, making the installation process smoother and improving installation efficiency.

[0016] The beneficial effects of this utility model are as follows: The pull-out core rope has interlocking buckle structures on both sides, extending along the length edge of the pull-out core rope. This allows the pull-out core rope to spirally form a support tube, which provides expansion support to the socket of the elastic sleeve. The through hole of the support tube is then connected to the handlebar sleeve. The pull-out part extends outward through the through hole to the outside of the handlebar. By pulling the pull-out part, the support tube is removed from the socket, allowing the elastic sleeve to wrap around the outside of the handlebar under elastic reset. This improves the ease and smoothness of installation, thereby increasing installation efficiency. It changes the traditional method of relying on axial thrust for connection, avoiding the problem that a large axial thrust is required to achieve connection due to the high elasticity and low surface friction coefficient of silicone rubber. This reduces installation difficulty, allowing the handlebar sleeve and handlebar to be quickly connected and installed, further improving installation convenience. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0026] To make the technical problem to be solved, the technical solution and the beneficial effects of this utility model clearer, the following describes the solution in further detail with reference to the accompanying drawings and embodiments.

[0027] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this scheme and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0028] In this embodiment, refer to Figures 1-5 The pull-out silicone rubber handlebar grip, specifically implemented therein, includes an elastic sleeve 100 and a pull-out core rope. The pull-out core rope has buckle structures on both sides that can be paired and fastened together. These buckle structures extend along the length of the pull-out core rope, allowing it to spirally encircle and form an axially extending support tube 200. The support tube 200 has a through hole 201 inside, and the elastic sleeve 100 has a through-hole 101 inside. The elastic sleeve 100 is paired and fitted onto the support tube 200 through the 101, allowing the support tube 200 to provide expansion support force to the 101 of the elastic sleeve 100. One end of the support tube 200 has a pull-out portion 202, which extends through the through hole 201 to the other end of the support tube 200.

[0029] The support tube 200 provides a stable expansion support force to the elastic sleeve 100, making the elastic sleeve 100 more evenly stressed during the sleeve connection process. This effectively reduces the local twisting and jamming that are prone to occur during the sleeve connection process. At the same time, the support expansion of the elastic sleeve 100 facilitates the quick positioning and connection of the elastic sleeve 100 with the handlebar, providing guidance and positioning for quick sleeve connection and installation.

[0030] The outer surface of the elastic sleeve is provided with anti-slip texture 102. The anti-slip texture is arranged along the axial direction on the outer surface of the elastic sleeve 100. The anti-slip texture 102 can be any one type of point, line, or surface, or any combination of two types or three types.

[0031] By setting anti-slip textures 102 along the axial direction on the outer surface of the elastic sleeve, and the anti-slip textures 102 adopt different forms or combinations such as dots, lines or surfaces, the friction between the hand and the handlebar grip can be effectively increased, avoiding slippage of the hand due to sweating during riding, thus improving riding safety and control. At the same time, it also helps to improve the problem of easy slippage during installation caused by the low surface friction coefficient of traditional handlebar grips, and assists the installation process to a certain extent.

[0032] Alternatively, in some embodiments, the resilient sleeve 100 is made of silicone rubber or rubber.

[0033] Specifically, refer to Figure 1 and Figure 5 In some embodiments, the anti-slip texture 102 of the elastic sleeve 100 is composed of raised anti-slip lines, which are arranged in a crisscross pattern on the outer surface of the elastic sleeve 100.

[0034] Specifically, in some embodiments, the anti-slip texture 102 of the elastic sleeve 100 is composed of raised anti-slip bumps, which are arranged on the outer surface of the elastic sleeve 100, and raised limiting portions are formed at both ends of the elastic sleeve 100.

[0035] The buckle structure includes a first buckle portion 203 with an inward opening and a second buckle portion 204 with an outward opening. The inner side of the first buckle portion 203 has a first buckle groove 205 and a first buckle protrusion 206. The outer side of the second buckle portion 204 has a second buckle groove 207 for mating and fastening the first buckle protrusion 206 and a second buckle protrusion 208 for mating and fastening the first buckle groove 205.

[0036] This specific snap-fit ​​structure design allows the first snap-fit ​​part 203 and the second snap-fit ​​part 204 to precisely match and engage when the pull-out core rope spirals around to form the support tube 200, providing a stable and reliable connection structure for the support tube 200 and ensuring its structural integrity. This snap-fit ​​structure also enables the pull-out core rope to quickly and accurately form the support tube 200 during installation and positioning, thereby enhancing support for the silicone elastic sleeve 100.

[0037] The first snap-fit ​​groove 205 and the second snap-fit ​​groove 207 have tapered slopes inside. This tapered slope design guides and positions the snap-fit ​​structure during the mating and engaging process, making it easier and more accurate for the first snap-fit ​​protrusion 206 and the second snap-fit ​​protrusion 208 to enter their corresponding grooves, further improving installation convenience and precision. Simultaneously, the tapered slope increases the stability of the connection after snap-fit ​​engagement, preventing loosening or detachment during use and solving the problem of weak connections caused by localized twisting or jamming in traditional installation methods.

[0038] The pull-out core rope continuously spirals around the first snap-fit ​​part 203 and the second snap-fit ​​part 204, and then heat-seales to form a hollow support tube 200. The continuous spiral winding and heat-sealing of the pull-out core rope to form the hollow support tube 200 gives it good strength and stability, providing reliable expansion support for the elastic sleeve 100. During installation, the structural characteristics of the support tube 200 avoid the local twisting and jamming problems caused by the high elasticity of silicone rubber in traditional sleeve methods, making the installation process smoother and improving installation efficiency.

[0039] The specific operating principle in this embodiment is as follows:

[0040] A buckle structure that can be paired and fastened is provided on both sides of the pull-out core rope, so that the first buckle part 203 with the opening facing inward and the second buckle part 204 with the opening facing outward extend along the length edge of the pull-out core rope, so that the pull-out core rope is paired with the first snap-fit ​​groove and the second snap-fit ​​protrusion by spiraling around it, and the second snap-fit ​​groove is paired with the first snap-fit ​​protrusion. A support tube 200 is formed by hot air welding the inside of the through hole 201. The elastic sleeve 100 is pre-fitted and installed on the support tube 200 through the sleeve hole 101, so that the support tube 200 can provide expansion support force to the sleeve hole 101 of the elastic sleeve 100.

[0041] The elastic sleeve 100 is fitted onto the support tube 200 through the fitting hole 101, so that the through hole 201 of the support tube 200 is fitted with the handlebar sleeve. The pull-out part 202 extends outward from the handlebar through the through hole 201. By pulling out the pull-out part 202, the support tube 200 is pulled out from the fitting hole 101, so that the first snap part 203 and the second snap part 204 are separated to form a pull-out core rope. Under elastic reset, the elastic sleeve 100 can be wrapped around the outside of the handlebar through the fitting hole, which improves the convenience and smoothness of installation, thereby improving the installation efficiency. It changes the traditional method of fitting by axial thrust, avoiding the problem that a large axial thrust is required to achieve fitting due to the high elasticity and low surface friction coefficient of silicone rubber material. It reduces the installation difficulty and allows the handlebar sleeve to be quickly fitted and installed, further improving the convenience of installation.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
