[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1
[0026] Please see Figure 1 - Figure 7 This utility model provides the following technical solution: a lightweight bicycle handlebar stopper, including an expansion locking ring 1. The expansion locking ring 1 has an overall structure similar to a thin-walled tube, and can be made into different sizes according to the inner diameter of the bicycle handlebar tube. It can be made of metal materials such as titanium alloy. The outer surface of the expansion locking ring 1 is used to compress and fasten the bicycle handlebar tape. By adjusting the product specifications and dimensions, it can be designed with different sizes of working contact surfaces to ensure reliable performance. The expansion locking ring 1 adopts a bent shape and is composed of an expansion area 11 and a pressing part 12. The pressing part 12 can provide a fitting fulcrum and locking limit for the locking plate 2. The thickness of the expansion locking ring 1 is uneven. The expansion zone 11 and the clamping part 12 are centrally located with a smaller thickness and better elasticity, while the ends are thicker and stronger. This design fully utilizes the toughness of the metal material and provides a larger radial centrifugal clamping force. The clamping part 12 in the expansion locking ring 1 has a limiting groove 121 for installing the locking plate 2. The surface roughness of the inner and outer surfaces of the expansion locking ring 1 can be adjusted as needed, and the appearance can also be designed and processed as required. The expansion locking ring 1 is designed with weight reduction holes to achieve a lightweight design. The hollowed-out position can accommodate the rebound filling of the bicycle handlebar tape to provide greater adhesion and ensure a firm and reliable installation.
[0027] The locking plate 2 is a nearly circular sheet, and its thickness can be installed within the limiting groove 121 of the expansion locking ring 1. The locking plate 2 can be made of metal materials such as titanium alloy, and can also be designed in different sizes and specifications as needed. The locking plate 2 is thicker on the outside and thinner in the middle to ensure that its strength meets the locking requirements, while achieving the requirements of lightweight. The entire locking plate 2 can be designed with weight reduction holes, and two pressing ports 21 and releasing ports with different radii are formed on the outside. The locking plate 2 can form two states with the expansion locking ring 1 by rotation.
[0028] In the first state, the release port 22 is located in the pressing port 21, and the expansion locking ring 1 is in its normal state. In the second state, the pressing port 21 is located in the pressing port 21, and the pressing port 21 pushes the pressing part 12 outward, thereby pushing the expansion area 11 outward to expand inside the bicycle handlebar.
[0029] Specifically, a ramp 23 is formed at the front end of the clamping port 21 near the direction of locking rotation, and a stop 24 is formed at the end of the clamping port 21 away from the ramp 23. When the locking plate 2 is in the second state in the expansion locking ring 1, the ramp 23 and the stop 24 are in a protruding state at both ends of the clamping part 12, which can prevent loosening. The ramp 23 and the stop 24 form a locking force on the clamping port 21. This locking force can ensure that the handlebars do not loosen when the bicycle is vibrating or bumping.
[0030] Specifically, the radius of the clamping port 21 is larger than that of the release port 22. The larger radius of the clamping port 21 can firmly support the expansion locking ring 1 outward to stably provide the tightening force and prevent the expansion self-locking ring from rebounding and loosening. The smaller radius of the release port 22 is slightly larger than the inner diameter of the clamping part 12, and can be installed into the limiting groove 121 by appropriate compression.
[0031] Specifically, it also includes adapter 3, which can be made of metal or other materials and has the strength to meet the requirements for plug installation or removal. The adapter 3 has a positioning plate 31 in the middle, multiple extended insert plates 32 at one end, and a wrench socket 33 at the other end for use with other tools, making it convenient for operators to install and remove.
[0032] Specifically, multiple insert plates 32 are arranged in a circular pattern, and the locking plate 2 has a slot 25 for inserting the insert plate 32 through from one side. After insertion, the rotation locking operation can be completed.
[0033] Specifically, a hollow through hole 26 is provided at the center of the locking piece 2, which ensures structural strength while reducing weight. Example 2
[0034] Please see Figure 8 In this embodiment, a decorative panel 27 is simply provided in the through hole 26. The decorative panel 27 can be customized in shape, pattern, etc. to meet diverse needs.
[0035] The working principle and usage process of this utility model: Lightweight bicycle handlebar plugs can be made into different specifications as needed. Before use, the operator needs to select the appropriate specification of handlebar plug according to the diameter of the internal cavity tube of the bicycle handlebar and the thickness of the handlebar tape material. The expansion locking ring 1 is deformed by appropriate squeezing so that the expansion locking ring 1 can be assembled with the locking plate 2. At this time, the release port 22 is located in the limiting groove 121 of the pressing part 12. Since the diameter of the release port 22 is small, it cannot squeeze the expansion locking ring 1. The handlebar plug assembly is completed and ready for installation and use.
[0036] During installation, the operator needs to leave an appropriate length at the end of the handlebar tape, fold it back and insert it into the internal cavity of the bicycle handlebar. Then, use the expansion lock ring 1 to press the end of the handlebar tape into the handlebar. The axis of the expansion lock ring 1 should be parallel to the axis of the end of the handlebar. The outer surface of the expansion lock ring 1 should be in full contact with the handlebar tape. The insertion depth should ensure that the handlebar tape is securely fastened and the handlebar plug is installed firmly.
[0037] After inserting the plug into the appropriate position, insert the plate 32 on the adapter 3 into the slot 25, and rotate the locking plate 2 using the adapter 3 and a wrench. Figure 4 The locking plate 2 shown needs to be rotated counterclockwise. When rotating, the inclined platform 23 will squeeze the pressing part 12 outward, and at the same time, the pressing part 12 will drive the expansion area 11 to squeeze outward. By rotating, the pressing port 21 is placed in the pressing part 12. At this time, the two ends of the pressing part 12 are positioned by the inclined platform 23 and the stop block 24 to prevent loosening. Since the diameter of the pressing port 21 is larger than that of the release port 22, the expansion locking ring 1 is expanded and squeezed to complete the locking.
[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
