[0082] The following description, in conjunction with the accompanying drawings of the preferred embodiments of the present invention, is intended to enable those skilled in the art to implement the invention based on the statements herein.

[0083] First, please refer to the following: Figures 1 to 12 As shown, the bicycle tube end cap of this utility model includes: a receiving sleeve 20, a cap assembly 30, a screw locking member 40, and a bolt 50.

[0084] The receiving sleeve 20 is a cylindrical body with an internal receiving space 21. The bottom end has a central through hole 22 communicating with the receiving space 21, and the top end has an open opening 23 communicating with the receiving space 21. The outer peripheral wall of the open opening 23 has an annular flange 24, and the inner peripheral wall has a snap-fit ​​groove 25. The upper end face of the annular flange 24 has a first engaging groove 241 near the edge, and the lower end face of the annular flange 24 has a second engaging groove 242 near the edge.

[0085] The cap assembly 30 includes a cap body 31. One side of the cap body 31 has two symmetrically arranged, outward-facing sliding grooves 311, and a cap edge 312 at its periphery. A baffle 313 is provided between the two sliding grooves 311. A positioning protrusion 314 is provided on each side between the two sliding grooves 311. A movable member 32 slides within each of the two sliding grooves 311. The two movable members 32 are elastically pushed outward by a pushing means. A sheet 321 extends from each other on both movable members 32. The sheets 321 of the two movable members 32 are mutually... The components are staggered, with a first hook 322 formed on the side of the end of the piece 321, and a second hook 323 formed on the side of the end of the piece 321 facing the cover 31. The first hook 322 is blocked by the positioning protrusion 314, and the second hook 323 is blocked by the baffle 313, thus limiting the outward movement of the two movable components 32. A locking block 324 protrudes from the opposite ends of the first hook 322 and the second hook 323 on the piece 321, which is then closed onto the receiving sleeve 20 by the sealing assembly 30. The opening 23 is provided. The cover edge 312 of the cover body 31 engages with the first engaging groove 241 of the receiving sleeve 20. The two movable parts 32 are elastically pushed outward by a pushing means, so that the locking blocks 324 of the two movable parts 32 engage with the locking grooves 25 of the receiving sleeve 20, achieving a positioning effect. One of the two movable parts 32 is provided with a positioning part 325. In this embodiment, the positioning protrusion 314 is provided with a first guide part 3141. The baffle 313 is provided with a positioning part 325 on each side of the end away from the cover body 31. The second guide part 3131, the first hook part 322 is provided with a third guide part 3221 corresponding to the first guide part 3141, and the second hook part 323 is provided with a fourth guide part 3231 corresponding to the second guide part 3131, so as to facilitate the simple assembly of the two movable parts 32 and the cover body 31. The locking block 324 is provided with a guide slope 3241 on each side. The pushing means is that a spring 60 is provided between the two movable parts 32 and the baffle 313 respectively, so as to elastically push the two movable parts 32 outward.

[0086] The screw-locking component 40 has a screw hole 41 at its center and outwardly extending pawl plates 42 around its periphery.

[0087] The bolt 50 has a through hole 51 at its center, and a swivel groove 52 is provided at the upper end of the through hole 51.

[0088] More specifically, in this embodiment, the two movable parts 32 are respectively provided with a first hook 322 and a second hook 323. The first hook 322 is blocked by the positioning protrusion 314, and the second hook 323 is blocked by the baffle 313, thus forming an outward movement limit for the two movable parts 32. Therefore, the stability and strength of the combination between the two movable parts 32 and the cover 31 are increased. In addition, the two movable parts 32 can be individually configured with a first hook 322. A spring 60 is provided between the two movable parts 32 in conjunction with the pushing means. The spring 60 elastically pushes the two movable parts 32 outward. The first hook 322 is blocked by the positioning protrusion 314, thus forming an outward movement limit for the two movable parts 32. Since it is not necessary to provide a second hook 323 and a baffle 313, the thickness of the cover assembly 30 can be reduced.

[0089] In actual use, the screw-locking component 40 is housed inside the bicycle tube (front fork stem 80), and the pawl 42 is used to lock and position it against the inner wall of the front fork stem 80. A bicycle handlebar 90 is connected to the upper end of the front fork stem 80. The receiving sleeve 20 is fitted inside the front fork stem 80 and positioned above the screw-locking component 40. The bolt 50 passes through the central through hole 22 of the receiving sleeve 20 and engages with the screw hole 41 of the screw-locking component 40, so that the second engaging groove 242 of the receiving sleeve 20 engages with the top of the front fork stem 80. The receiving sleeve 20 and the front fork stem 80 are firmly connected. Then, press the outer side of the two movable parts 32 with your fingers. The two movable parts 32 are displaced and squeeze the spring 60, which is guided by the guide slope 3241 of the locking block 324. The cap assembly 30 is directly and simply covered onto the opening 23 of the receiving sleeve 20. When the fingers are released, the two movable parts 32 are pushed outward by the spring 60. The locking blocks 324 of the two movable parts 32 are inserted into the locking groove 25 of the receiving sleeve 20 and locked in place. The positioning part 325 of one of the two movable parts 32 is inserted into the clamp 91 of the bicycle handlebar 90, which restricts the cap assembly 30 and prevents it from rotating. The cap assembly 30 is then closed onto the opening 23 of the receiving sleeve 20.

[0090] When you want to remove the cap assembly 30, as follows Figures 13 to 15 As shown, pressing the outer side of the two movable parts 32 with a finger causes the two movable parts 32 to displace and squeeze the spring 60. With the guide slope 3241 of the locking block 324 as a guide, the locking block 324 can be pulled out of the latching groove 25 of the receiving sleeve 20. When the finger is released, the two movable parts 32 are pushed outward by the spring 60, and the locking block 324 of the two movable parts 32 returns to its original position, thereby forming a quick assembly and disassembly of the cap assembly 30 and the receiving sleeve 20.

[0091] Furthermore, it is possible to Figure 16 As shown, the accommodating sleeve 20 provides a accommodating space 21 for storing the bicycle tools 100 (tool set), and can be used as follows: Figure 17As shown, the accommodating space 21 of the accommodating sleeve 20 is matched with the through hole 51 of the bolt 50 for the bicycle tool 100 (hex wrench) to be inserted and stored, so as to facilitate carrying and taking out for use on the bicycle.

[0092] Furthermore, please refer to the following: Figures 18 to 29 As shown, the bicycle tube end cap of this utility model includes: a stem 10, a receiving sleeve 20, a cap assembly 30, a screw lock 40, and a bolt 50.

[0093] The faucet 10 has a vertical riser hole 11 at its rear end and a horizontal crossbar hole 12 at its front end.

[0095] The cover assembly 30 includes a cover body 31, which corresponds in shape to the closing part 14 and can be opened or closed without tools. This allows for the operative opening or closing of the riser hole 11 and the receiving chamber 13. The cover body 31 has two symmetrically arranged outward-facing sliding grooves 311 on one side and a cover edge 312 at its periphery. Each of the two sliding grooves 311 has a baffle 313 formed inside its inner side. Each baffle 313 has a positioning protrusion 314 on both sides. A movable member 32 slides within each of the two sliding grooves 311 and is pushed outward by a pushing mechanism. With the two movable parts 32 extending towards each other, a single piece 321 is provided. A first hook 322 is formed on the side of the end of the single piece 321, and a second hook 323 is formed on the side of the end of the single piece 321 facing the cover 31. The first hook 322 is blocked by the positioning protrusion 314, and the second hook 323 is blocked by the baffle 313, thus limiting the outward movement of the two movable parts 32. In addition, a locking block 324 is protruding from the opposite end of the first hook 322 and the second hook 323 on the single piece 321, which is then closed onto the faucet by the sealing assembly 30. The cover 14 of the faucet 10 closes the accommodating chamber 13 and the opening 23 of the accommodating sleeve 20. The cover edge 312 of the cover body 31 engages with the cover 14 of the faucet 10. The two movable parts 32 elastically push outward, so that the locking blocks 324 of the two movable parts 32 engage with the locking part 131 of the faucet 10 and the locking groove 25 of the accommodating sleeve 20, achieving a positioning effect. One of the two movable parts 32 is provided with a positioning part 325. In this embodiment, the positioning protrusion 314 is provided with a first guide part 3141, and the baffle 313... A second guide portion 3131 is provided at one end away from the cover 31. The first hook portion 322 is provided with a third guide portion 3221 corresponding to the first guide portion 3141. The second hook portion 323 is provided with a fourth guide portion 3231 corresponding to the second guide portion 3131, so as to facilitate the simple assembly of the two movable parts 32 with the cover 31. A guide slope 3241 is provided on each side of the locking block 324. The pushing means is that a spring 60 is provided between the two movable parts 32 and the baffle 313 respectively, which elastically pushes the two movable parts 32 outward.

[0096] The screw-locking component 40 has a screw hole 41 at its center and outwardly extending pawl plates 42 around its periphery.

[0097] The bolt 50 has a through hole 51 at its center, and a swivel groove 52 is provided at the upper end of the through hole 51.

[0098] More specifically, in this embodiment, the two movable parts 32 are respectively provided with a first hook 322 and a second hook 323. The first hook 322 is blocked by the positioning protrusion 314, and the second hook 323 is blocked by the baffle 313, thus forming an outward movement limit for the two movable parts 32. Therefore, the stability and strength of the combination between the two movable parts 32 and the cover 31 are increased. In addition, the two movable parts 32 can be configured with the first hook 322 independently. The first hook 322 is blocked by the positioning protrusion 314, thus forming an outward movement limit for the two movable parts 32. Since the second hook 323 and the baffle 313 do not need to be provided, the thickness of the cover assembly 30 can be reduced.

[0099] In actual use, the screw-locking component 40 is housed inside the bicycle's stem (front fork stem 80), and the pawl 42 is used to engage with the inner wall of the front fork stem 80 for positioning. The upper end of the front fork stem 80 is inserted into the stem hole 11 of the handlebar 10 for connection. The crossbar hole 12 of the handlebar 10 clamps and fixes the handlebar 70. The receiving sleeve 20 is fitted inside the front fork stem 80 and positioned above the screw-locking component 40. The bolt 50 passes through the central through hole 22 of the receiving sleeve 20 and engages with the screw hole 41 of the screw-locking component 40, so that the second engaging groove 242 of the receiving sleeve 20 engages with the top of the front fork stem 80, and the receiving sleeve 20 and the front fork stem 80 are firmly connected. Then, press the outer side of the two movable parts 32 with your fingers to... The two movable parts 32 displace and compress the spring 60, which is guided by the guide slope 3241 of the locking block 324, so that the cap assembly 30 is directly and simply covered onto the capping part 14 of the faucet 10. When the fingers release the two movable parts 32, the spring 60 pushes the two movable parts 32 outward, and the locking blocks 324 of the two movable parts 32 are inserted into the locking part 131 of the faucet 10 and locked in place with the locking groove 25 of the receiving sleeve 20. The positioning part 325 of one of the two movable parts 32 is locked into the clamping mouth 111 of the faucet 10, restricting the cap assembly 30 so that it cannot rotate, thus completing the process of covering the capping part 14 of the faucet 10 with the cap assembly 30, sealing the receiving chamber 13 and the opening 23 of the receiving sleeve 20.

[0100] When removing the cap assembly 30, press the outer sides of the two movable parts 32 with your fingers. This causes the two movable parts 32 to shift and compress the spring 60. The guide slope 3241 of the locking block 324 guides the spring 60, allowing it to be pulled out of the locking part 131 of the faucet 10 and the latching groove 25 of the receiving sleeve 20. Releasing the fingers from the two movable parts 32 causes the spring 60 to push them outwards, returning the locking blocks 324 of the two movable parts 32 to their original positions. This allows for quick assembly and disassembly of the cap assembly 30 and the receiving sleeve 20.

[0101] Furthermore, it is possible to Figure 30As shown, the accommodating chamber 13 of the faucet 10 and the accommodating space 21 of the accommodating sleeve 20 are used to house and store the bicycle tool 100. The accommodating space 21 of the accommodating sleeve 20 is used to fit the through hole 51 of the bolt 50 for inserting and storing the bicycle tool 100, so as to facilitate carrying and taking it out for use.

[0102] The following beneficial effects can be obtained from the structure of the above specific embodiments:

[0103] The bicycle tube end cap of this utility model provides convenient storage space for bicycle tools 100 and parts, making it easy to carry and take out for use. The cap assembly 30 is designed to snap onto the open opening 23 of the accommodating sleeve 20 or the capping part 14 of the handlebar 10, eliminating the need for tools to open or close, thus achieving convenient and quick disassembly and assembly, as well as effective dust and water protection.

[0104] The above are merely illustrative embodiments of this utility model and are not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model.
