Description

Technical Field

[0001] This utility model relates to the field of expandable handlebar technology, and in particular to an expandable handlebar for road bikes and a road bike. Background Technology

[0002] A road bike is a type of bicycle designed specifically for riding on public roads. Road bikes have handlebar plugs at the ends of the handlebars to seal the openings at the handlebar ends. Current handlebar plugs have fixed sizes and cannot fit all handlebar sizes. While some handlebar plugs offer some expansion, the expansion angle is small, limiting their usability. Utility Model Content

[0003] The main objective of this invention is to provide a road bike expander plug that can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] The road bike expandable handlebar plug includes a top cover, an expansion tube, a base, and fasteners. The top cover has a first through hole in the middle, and the expansion tube has a second through hole in the middle. The bottom of the side wall of the expansion tube has several opening slots facing upwards. The base is a frustum structure with a smaller top and a larger bottom. The side of the base has a locking block. The base extends from bottom to top into the bottom of the expansion tube, and the locking block is engaged in the opening slots. The fasteners pass through the first through hole and the second through hole in sequence and are spirally connected to the base. As the fasteners rotate clockwise and counterclockwise, the side wall of the base expands the expansion tube or the expansion tube automatically retracts due to its own elasticity.

[0006] In a preferred embodiment of this invention, the fastener has a threaded section at the bottom, and the base has a third through hole in the middle. The third through hole contains a nut integrally formed with the base (the base is made of plastic or the like, and the nut is a metal part; the base and the nut are integrally injection molded). The threaded section is spirally connected to the nut.

[0007] In this invention, the fastener can be a bolt.

[0008] In a preferred embodiment of this invention, the upper part of the top cover has an inverted conical surface centered on the first through hole, and the top of the fastener has an inverted conical body that fits into the inverted conical surface. This fitting arrangement of the inverted conical body and the inverted conical surface makes tightening / loosening the fastener easier.

[0009] In a preferred embodiment of this invention, the fastener has a tightening / loosening hole on its top. The tightening / loosening hole facilitates tightening / loosening with tools.

[0010] In a preferred embodiment of this invention, the lower part of the top cover is provided with several positioning blocks, and the top of the expansion tube is provided with several positioning grooves, with the positioning blocks engaging and positioning with the positioning grooves.

[0011] In a preferred embodiment of this invention, the outer surface of the expansion tube is provided with a threaded strip to enhance friction.

[0012] In a preferred embodiment of this invention, the top cover and the expansion tube are integrally formed.

[0013] A road bike, including the aforementioned road bike expander, wherein the road bike expander is disposed on the handlebars of the frame body.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In use, the expansion plug for road bikes is inserted from bottom to top into the bottom of the expansion tube, and the locking block is inserted into the opening groove. Then, the fastener passes through the top cover and the expansion tube in sequence and is threadedly connected and fixed to the bottom support. As the fastener rotates forward and backward, the expansion tube is opened by the inclined design of the side wall of the bottom support due to its own elasticity, or the expansion tube automatically closes due to its own elasticity. Moreover, this design allows the expansion tube to open at a larger angle. Attached Figure Description

[0024] Example

[0025] like Figures 1-7 As shown, a road bike expandable handlebar plug includes a top cover 1, an expansion tube 2, a base 3, and fasteners 4. The top cover 1 has a first through hole 11 in the middle, and the expansion tube 2 has a second through hole in the middle. The bottom of the side wall of the expansion tube 2 has several opening slots 21 facing upwards. The base 3 has a frustum structure with a smaller top and a larger bottom. The side of the base 3 has a locking block 32. The base 3 extends from bottom to top into the bottom of the expansion tube 2, and the locking block 32 is engaged in the opening slots 21. The fasteners 4 pass through the first through hole 11 and the second through hole in sequence and are spirally connected to the base 3. As the fasteners 4 rotate clockwise and counterclockwise, the side wall of the base 3 expands the expansion tube 2 or the expansion tube 2 automatically retracts due to its own elasticity (the expansion tube 2 is made of plastic).

[0026] In a preferred embodiment of this utility model, the fastener 4 has a threaded section 41 at the bottom, the base 3 has a third through hole 31 in the middle, and a nut 5 integrally formed with the base 3 is provided in the third through hole 31 (the base 3 is made of plastic or the like, the nut 5 is a metal part, and the base 3 and the nut 5 are integrally injection molded), and the threaded section 41 is spirally connected to the nut 5.

[0027] In this utility model, the fastener 4 can be a bolt.

[0028] In a preferred embodiment of this invention, the upper part of the top cover 1 is provided with an inverted conical surface 12 centered on the first through hole 11, and the top of the fastener 4 is provided with an inverted cone 42, which is adapted to the inverted conical surface 12. The use of the matching arrangement of the inverted cone 42 and the inverted conical surface 12 makes it easier to tighten / loosen the fastener 4.

[0029] In a preferred embodiment of this invention, the fastener 4 has a tightening / loosening hole 43 on its top. The tightening / loosening hole 43 facilitates tightening / loosening with tools.

[0030] In a preferred embodiment of this invention, the lower part of the top cover 1 is provided with several positioning blocks 13, and the top of the expansion tube 2 is provided with several positioning grooves 23, and the positioning blocks 13 are engaged with the positioning grooves 23 for positioning.

[0031] In a preferred embodiment of this invention, the outer surface of the expansion tube 2 is provided with a threaded strip 22 to enhance friction.

[0032] In a preferred embodiment of this invention, the top cover 1 and the expansion tube 2 are integrally formed.

[0033] A road bike, including the aforementioned road bike expander, wherein the road bike expander is disposed on the handlebars of the frame body.

[0034] In use, the expansion plug for road bikes is inserted from bottom to top into the bottom of the expansion tube, and the locking block is inserted into the opening groove. Then, the fastener passes through the top cover and the expansion tube in sequence and is threadedly connected and fixed to the bottom support. As the fastener rotates forward and backward, the expansion tube is opened by the inclined design of the side wall of the bottom support due to its own elasticity, or the expansion tube automatically closes due to its own elasticity. Moreover, this design allows the expansion tube to open at a larger angle.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model.
