Description

Bicycle faucet

This creation is related to bicycle components; in particular, it refers to a bicycle faucet.

In modern society, bicycles have become a leisure transportation tool that modern people are accustomed to. People can choose suitable models according to their personal needs and the applicable environment, or they can purchase components and assemble them by themselves. Due to the different body types of riders, a bicycle with adjustable handlebar height came into being. The bicycle frame of the aforementioned model includes a front fork shaft tube passing through a head tube, and a faucet is sleeved on the front fork shaft tube passing through the head tube, and the faucet is connected with a handle for holding.

The above-mentioned known structure achieves the purpose of adjusting the height of the handle by fixing the faucet to a predetermined position of the front fork shaft tube. However, the faucet is easily enlarged gradually as it is tightened and fixed to the front fork shaft tube. The faucet has a slight axial displacement relative to the front fork shaft tube due to the pressing force of the faucet, which causes a slight gap between the bottom edge of the faucet and the upper bead set sleeved on the top edge of the head tube, which results in riding Security concerns. For example, when riding a bicycle and encountering bumpy roads and causing up and down vibrations, relative sliding between the faucet and the front fork axle tube is likely to occur, which increases the instability of the bicycle structure.

In view of this, the purpose of this creation is to provide a bicycle faucet with good stability.

In order to achieve the above purpose, this creation provides a bicycle faucet, which includes a body and a tension ring. The body has a first coupling portion and a second coupling portion; the first coupling portion is used to connect the handle; the second coupling portion is used to connect the front fork shaft tube and has a first sleeve hole; the first The sleeve hole is used to connect the front fork shaft tube and has a first hole section and a second hole section; the first hole section is connected to the second hole section; the aperture of the second hole section faces away from the first hole The direction of the segment gradually expands. The tightening ring has a second set of holes, and its outer periphery has an annular inclined wall section; the tightening ring has a top edge and a bottom edge that deviate from each other; the outer diameter of the annular inclined wall section corresponds to the first The two holes gradually expand from close to the top edge and away from the bottom edge. Thereby, when the body and the tightening ring are sleeved on the front fork shaft tube, the annular inclined wall section of the tightening ring abuts the second hole section, and an external force is applied to reduce the first set of holes The second hole section presses the annular inclined wall section, and forces the pressing ring to move along the expanding direction of the outer diameter of the annular inclined wall section.

The effect of this creation is that when the external force is applied to reduce the aperture of the first set of holes, and the second hole section presses the annular inclined wall section, the compression ring is forced to be along the outer diameter of the annular inclined wall section. When moving in the expansion direction, the bottom edge of the tightening ring will abut the upper edge of the upper bead headset to avoid a gap between the bicycle faucet and the upper bead headset.

In order to explain the creation more clearly, the preferred embodiments are described in detail below in conjunction with the drawings. Please refer to FIG. 1, which is a bicycle including a bicycle faucet 100 according to a preferred embodiment of the invention. The bicycle includes a frame 200, a front fork and a handle 300. The front end of the frame 200 has a head tube 201. The front fork has a front fork shaft tube 400 that passes through the lower bead headset 203 and then the head tube 201, and then an upper bead headset 202 is sleeved on the front. After the fork shaft tube 400, the bicycle faucet 100 is sleeved on the front fork shaft tube 400, and then the handle 300 is connected to the faucet 100. The purpose of the above-mentioned upper bead headset 202 and lower bead headset 203 is to prevent dust and impurities from entering the head tube 201 to ensure that the front fork axle tube 400 can rotate smoothly relative to the head tube 201 of the frame 200.

As shown in FIGS. 2 and 3, the bicycle faucet 100 of this embodiment includes a body 10 and a tension ring 20. Wherein, the main body 10 has a first joining portion 11, a second joining portion 12, two protruding portions 13, a first slit 14, and a tightening means 15. The first coupling portion 11 is connected to the second coupling portion 12 in a rotatable manner, and one end of the first coupling portion 11 has a pair of pivot ears 112, and the other end has a through hole 11a. The handle 300 is inserted through the through hole 11 a, and the pair of pivot ears 112 is pivotally connected to one end of the second joining portion 12.

More specifically, the bicycle faucet 100 further includes a fork pin assembly 16, and each of the pivot ears 112 of the first coupling portion 11 has a through hole 112 a; the second coupling portion 12 has a through hole 12 a. The fork pin assembly 16 includes a bolt 162, a first abutting member 164 and a second abutting member 166. The first abutting member 164 has a through hole 164a, a part of the first abutting member 164 is in the through hole 112a of a pivot ear 112 and the through hole 12a of the second joint 12, and the other part abuts against the pivot ear 112 of the through hole 112a periphery. The second abutting member 166 has a screw hole 166a and a positioning block 166b, and the outer side of the pivot lug 112 corresponding to the second abutting member 166 has a positioning groove 112b, and a part of the second abutting member 166 is in another Of the through hole 112a of a hinge 112 and the through hole 12a of the second joint portion 12, the other part abuts against the periphery of the through hole 112a of the hinge 112, and the positioning block 166b of the second abutting member 166 is engaged with The through hole 112a is restricted in the positioning groove 112b. Furthermore, the bolt 162 sequentially passes through the through hole 164a of the first abutting member 164, the through hole 112a of one of the pair of pivot ears 112, the through hole 12a of the second joint 12, and the pair of pivot ears 112. The through hole 112 a of the other one is finally locked in the screw hole 166 a of the second abutting member 166. The aforementioned corresponding design of the positioning block 166b and the positioning groove 112b cleverly locks the bolt 162 into the screw hole 166b of the second abutting member 166 without driving the second abutting member 166 to rotate. After the bolt 162 is tightened, the first abutment member 164 and the second abutment member 166 will respectively force the periphery of the through hole 112a of each of the pivot ears 112, so that the two pivot ears 112 are pressed against the second joint 12 , The positional relationship of the first coupling portion 11 relative to the second coupling portion 12 can be fixed. However, the bicycle faucet and the handle do not have to be combined with each other in the aforementioned manner. In other embodiments, the first joint part and the second joint part may be an integral pipe in a curved tube or a straight tube. Therefore, the first joint part There is no need to provide the pair of pivot ears and the fork pin assembly, the first joint portion directly defines a through hole, and the handle is directly inserted into the through hole to be combined with the bicycle faucet.

As shown in FIGS. 4 to 6, the second coupling portion 12 has a first sleeve hole 122, and the bicycle faucet 100 is connected to the front fork shaft tube 400 in such a way that the first sleeve hole 122 is sleeved on the front fork shaft tube 400. The shaft tube 400 is connected. The first set of holes 122 has a first hole section 122a and a second hole section 122b. The second hole section 122b is connected to the first hole section 122a, and the aperture of the second hole section 122b gradually expands away from the first hole section 122a.

The two protruding portions 13 are formed on the outer peripheral surface of the second coupling portion 12 of the main body 10 along the axial direction. The two protruding portions 13 are arranged adjacent to each other and a concave portion 17 is formed between them.

The first groove 14 is formed along the axial direction of the second coupling portion 12 of the main body 10. The first cut groove 14 communicates with the outside of the body 10 and the first sleeve hole 122. The first groove 14 cuts through the two raised portions 13 and the concave portion 17, so that the two raised portions 13 and the concave portion 17 respectively form half sides on both sides of the first groove 14. The first groove 14 has a first width W1. When the tightening means 15 generates an external force F to act on the body 10, the first width W1 (refer to FIG. 6) is reduced to a second width W2 (refer to FIG. 7) ), thereby reducing the aperture of the first set of holes 122.

The tightening means 15 includes at least one pair of perforations and at least one forcing member. The at least one pair of perforations includes a first pair of perforations 151 and a second pair of perforations 152, wherein the first pair of perforations 151 is located in one of the raised portions 13, and one of the first pair of perforations 151 is located in the first section On one side of the trench 14, the other of the first pair of through holes 151 is located on the other side of the first section groove 14; the second pair of through holes 152 is located on the other raised portion 13, and one of the second pair of through holes 152 is located It is located on one side of the first groove 14, and the other hole of the second pair of holes 152 is located on the other side of the first groove 14.

The at least one forcing member includes a first forcing member 153 and a second forcing member 154, wherein the first forcing member 153 passes through the first pair of perforations 151, and the second forcing member 154 passes through the second pair of perforations 152. As shown in FIG. 5, the first forcing member 153 has a head 153a and a body 153b connected to the head 153a. The body 153b passes through the two perforations of the first pair of perforations 151, and the head 153a abuts against One of the perforated edges. The second forcing member 154 has a head 154a and a body 154b connected to the head 154a. The body 154b passes through the two through holes of the second pair of through holes 152, and the head 154a abuts against the periphery of one of the through holes. More specifically, one of the pairs of perforations in this embodiment is a flat hole with a smooth wall, the other of the pairs of perforations is a screw hole, and each of the forcing members is a bolt. The body 153b of the first forcing member 153 has a threaded section 153c; the threaded section 153c of the first forcing member 153 will lock with the screw holes 151b of the first pair of through holes 151 after passing through the flat holes 151a of the first pair of through holes 151 Solid connection. Similarly, after passing through the flat holes 152a of the second pair of through holes 152, the threaded section 154c of the second forcing member 154 will be locked to the screw holes 152b of the second pair of through holes 152. However, in other embodiments, the perforations may all be flat holes, and the forcing member matched by each pair of perforations has a bolt and a nut; the body of the bolt will pass through a pair of perforated two flat holes, The threaded section of the bolt is combined with the internal threaded section of the nut. In addition, in order to avoid the first forcing member 153 that is locked in the pair of perforations first, the peripheries of the second pair of perforations 152 may be slightly deformed through the peripheries of the first pair of perforations 151, causing the axis of the second pair of perforations 152 to deviate. In turn, the second forcing member 154 is not conducive to being locked in the second pair of perforations 152. The arrangement of the recess 17 helps to appropriately reduce the structural strength between the two protruding portions 13, so that the first pair of perforations 151 and the second When the two pairs of perforations 152 are locked, they will not interact with each other. The first set of holes 122 can be segmented to reduce the aperture, making the assembly process easier.

It is supplemented that the bicycle faucet in other embodiments can use a bolt with a pair of perforations as a tightening means. In this case, the faucet body does not need to be provided with a recess. Or in other embodiments, the bicycle faucet may use a tightening ring as a tightening means, and the tightening ring is directly sleeved and tightened on the second joint, which can force the bicycle faucet to tighten the front fork of the bicycle. The purpose of the shaft tube, therefore, the faucet body does not need to be perforated.

The clamping ring 20 has a second sleeve hole 22, an annular inclined wall section 24 and a second slit 26. The second set of holes 22 is used to connect the front fork shaft tube 400. The annular inclined wall section 24 is located on the outer circumference of the tightening ring 20. Wherein, the compression ring 20 has a top edge 20a and a bottom edge 20b that deviate from each other, and the outer diameter of the annular inclined wall section 24 corresponds to the second hole section 122b from close to the top edge 20a and away from the bottom edge 20b gradually expanded. The second slit 26 of the tension ring 20 penetrates the outside of the tension ring 20 and the second sleeve hole 22 in the axial direction.

Therefore, referring to FIGS. 6 and 7, the tightening ring 20 and the body 10 are sleeved on the front fork shaft tube 400 in sequence, and the annular inclined wall section 24 of the tightening ring 20 abuts against the body 10 The second hole section 122b. We first pass the body 153b of the first forcing member 153 through the flat holes 151a of the first pair of perforations 151, and then lock it into the screw holes 151b of the first pair of perforations 151; then, the body 154b of the second forcing member 154 Pass through the flat holes 152a of the second pair of through holes 152 and lock into the screw holes 152b of the second pair of through holes 152. Wherein, when the threaded section 153c of the first forcing member 153 is gradually locked into the first pair of through holes 151, the head 153a of the first forcing member 153 will gradually approach the flat hole 151a, and finally the head 153a presses the flat hole 151a The head 153a of the first forcing member 153 and the threaded section 153c of the body 153b apply an external force F to the body 10 so that the first width W1 of the first groove 14 is gradually reduced to the second width W2. The aperture of the set of holes 122 is reduced. The second forcing member 154 also uses the aforementioned method together with the first forcing member 153 to reduce the first width W1 of the first groove 14 to the second width W2. The second hole section 122b of the first set of holes 122 presses the annular inclined wall section 24 of the clamping ring 20, forcing the clamping ring 20 to move along the expanding direction of the outer diameter of the annular inclined wall section 24, which is also That is, move toward the upper bead headset 202, so that the bottom edge 20b of the tightening ring 20 abuts against the top edge of the upper bead headset 202. It is added that, in other embodiments, if the bicycle faucet 100 is applied to a bicycle type with a gasket provided on the top of the bead headset, the bottom edge of the clamping ring is the top edge of the contact gasket.

In summary, compared to the conventional bicycle faucet without the tightening ring, the bicycle faucet of this creation can firmly resist the top edge of the beaded headset, and there is no need to worry about the bicycle faucet being relative to the front of the bicycle when it is shaken. The slip of the fork shaft tube prevents bicycle riders from having safety concerns.

In addition, it is worth mentioning that, as shown in FIG. 8, a right side cross-sectional view of the bicycle faucet 100 coupled to the front fork axle tube 400 is shown. It can be seen from FIG. 8 that the first joint portion 11 of the bicycle faucet 100 has at least one first wire hole 11b, and the second joint portion 12 has at least one second wire hole 12b for passing a wire body, such as a brake Line body such as line or shift line. For example, in this embodiment, the number of first wire holes 11b is two, and the number of second wire holes 12b is one. The brake wire can be hidden in the front fork shaft tube 400 and passed through the front fork shaft tube 400. The inside of the tube enters the second joint 12 of the bicycle faucet 100, then passes through the second thread hole 12b, and then passes through one of the first thread holes 11b into the tube body of the first joint 11, and finally from the other The first wire hole 11b passes through and connects to the brake member located on the handle 300. The aforementioned routing method can prevent the wire segment from being pulled and maintain the beautiful appearance of the bicycle. It is added that the number of wire holes can be changed according to demand and is not limited to the aforementioned content.

The above descriptions are only the preferred and feasible embodiments of this creation. Any equivalent changes made in the application of this creation specification and the scope of patent application should be included in the patent scope of this creation.
