Abstract
Description
Technical Field
[0001] This application relates to the technical field of bicycles, and more specifically, to a quick-mount stem structure and a bicycle. Background Technology
[0002] The stem and seat tube of a bicycle are key connecting components, responsible for firmly connecting the handlebars to the fork of the frame, thereby enabling control of the bicycle's direction.
[0003] The stem and seat tube are usually connected by screws and wedge nuts. Although this connection method is stable, it requires special tools for disassembly and assembly, which not only increases the labor and material costs, but also makes bicycle assembly inconvenient. Utility Model Content
[0004] The purpose of this application is to provide a quick-installation stem structure and bicycle, aiming to solve the defects of inconvenient stem assembly in related technologies.
[0005] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description or may be learned by practice of this application.
[0006] According to a first aspect of this application, a quick-installation stem structure is provided, comprising:
[0007] The stem has a slot on the side wall.
[0008] The vertical tube is configured such that the bottom insertion end of the handle is adapted to be inserted from the top opening of the vertical tube, and the side wall of the vertical tube has a movable channel.
[0009] A locator is assembled onto the vertical tube. The locator includes a sliding sleeve and a movable body. The sliding sleeve is slidably fitted onto the outside of the vertical tube. The movable body is movably disposed within the movable channel. The inner wall of the sliding sleeve is provided with a pressing part. The sliding sleeve has an unlocked position and a locked position in the vertical direction.
[0010] When the sliding sleeve is in the unlocked position, the handlebar is inserted into the vertical tube. When the slot of the handlebar is aligned with the movable body laterally, the sliding sleeve slides vertically from the unlocked position to the locked position. The squeezing part of the sliding sleeve squeezes the movable body to move laterally inward in the movable channel. The movable body part extends into the inner wall of the vertical tube to engage with the slot to form a snap-fit.
[0011] In one exemplary embodiment of this application, the active channel is tapered from the outside in, and the active body is configured as a rolling body.
[0012] In one exemplary embodiment of this application, the squeezing part is configured as a wedge-shaped surface facing the vertical tube, and the wedge-shaped surface gradually tilts towards the vertical tube along the direction from the locked position to the unlocked position.
[0013] In one exemplary embodiment of this application, the outer wall of the vertical tube is fixedly provided with an unlocking limiter and a locking limiter, and the sliding sleeve is slidably disposed between the unlocking limiter and the locking limiter. When the sliding sleeve moves to abut against the unlocking limiter, the sliding sleeve is in the unlocked position; when the sliding sleeve moves to abut against the locking limiter, the sliding sleeve is in the locked position.
[0014] In one exemplary embodiment of this application, the unlocking position is located below the locking position; the positioner further includes a compression spring, which is assembled inside the sliding sleeve. When the sliding sleeve slides from the locking position to the unlocking position, the compression spring compresses and stores energy; when the sliding sleeve slides from the locking position to the unlocking position, the compression spring releases energy and pushes the sliding sleeve to move.
[0015] In one exemplary embodiment of this application, a safety component is further included, disposed on one side of the sliding sleeve, for locking the sliding sleeve in a locked position.
[0016] In one exemplary embodiment of this application, the insurance component includes:
[0017] The mounting bracket is fixed relative to the vertical pipe;
[0018] The connecting plate is rotatably or fixedly connected to the mounting bracket and has a through hole.
[0019] The safety nut is fixedly connected to the sliding sleeve.
[0020] A safety bolt passes through the through hole and is rotatably connected to the connecting plate. After the safety bolt is threadedly connected to the safety sleeve, the connecting plate and the sliding sleeve are fixed relative to each other.
[0021] In one exemplary embodiment of this application, the movable body and the slot can form multiple snap-fit engagements in the circumferential direction of the vertical tube and the handle.
[0022] In one exemplary embodiment of this application, multiple card slots are provided along the length direction of the handle.
[0023] In one exemplary embodiment of this application, the movable body is characterized by having a plurality of such movable bodies spaced apart along the circumferential sidewall of the vertical tube.
[0024] According to a second aspect of this application, a bicycle is provided, including a stem quick-mount structure as described in any one of claims 1-10.
[0025] The exemplary embodiments of this application may have some or all of the following beneficial effects:
[0026] 1. In the stem quick-installation structure provided in the example embodiment of this application, the stem is inserted into the riser tube, and then the stem is smoothly slid along the riser tube until the movable part on the stem is aligned with the slot. At this time, simply move the sliding sleeve to the locking position. During the movement of the sliding sleeve, the pressing part applies a pressing force to the movable part. Under the action of the pressing force, the movable part moves from the outside to the inside of the movable channel, thereby gradually approaching the slot until the two are tightly engaged, forming a stable connection. At this time, part of the movable part is located in the movable channel and part is located in the slot. Therefore, the stem and the riser tube are relatively fixed. Through the above structure, the assembly process of the stem is greatly simplified, no additional tools are needed, providing great convenience to the user, and making the assembly process of the stem easy and quick;
[0027] 2. In the stem quick-installation structure provided in the example embodiment of this application, when the movable body is engaged with the slot, the movable body is positioned inside the movable channel. When the stem needs to be disassembled, the user only needs to slide the sliding sleeve to move the pressing part away from the movable body. During this process, the movable body smoothly moves to the outside of the movable channel using the inclined structure of the movable channel itself. At this time, the movable body can disengage from the slot, thereby allowing the stem to slide freely along the vertical tube. With this structure, the disassembly of the stem no longer requires any additional auxiliary tools, greatly simplifying the disassembly process and making the disassembly and assembly of the stem more efficient and easier.
[0028] 3. In the stem quick-installation structure provided in the example embodiment of this application, during the use of the stem, the compression spring continuously provides upward elastic force to the sliding sleeve, ensuring that the sliding sleeve is in close contact with the locking limit member, thereby allowing the sliding sleeve to be stably in the locked position. When the sliding sleeve is in the locked position, the pressing part can keep the movable body in a locked state with the slot, thereby improving the stability and reliability of the stem during use; when it is necessary to disassemble the stem, the user only needs to pull down the sliding sleeve until the sliding sleeve contacts the unlocking limit member, at which point the movable body can smoothly move to the outside of the movement channel. It is worth mentioning that even when the sliding sleeve is in the unlocked position, the sliding sleeve can still effectively block the movable body, ensuring that the movable body remains stable at the outer end of the movement channel, avoiding the risk of accidental detachment. When the user releases the sliding sleeve, the compression spring quickly releases its stored elastic potential energy, driving the sliding sleeve back to the locked position. Through the above structure, the stem installation and disassembly process is simplified, making the stem installation and disassembly process more efficient and easier.
[0029] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

[0040] like Figure 1 , Figure 2 and Figure 3 As shown in the embodiments of this application, a quick-installation stem structure is provided, comprising:
[0041] The handlebar 1 has a slot 11 on its side wall.
[0042] The vertical tube 2 is configured such that the bottom insertion end of the handle 1 is adapted to be inserted from the top opening of the vertical tube 2, and the side wall of the vertical tube 2 has a movable channel 21 passing through it;
[0043] Positioner 3 is assembled onto the vertical tube 2. Positioner 3 includes a sliding sleeve 31 and a movable body 32. The sliding sleeve 31 can be slidably sleeved on the outside of the vertical tube 2. The movable body 32 is movably disposed in the movable channel 21. The inner wall of the sliding sleeve 31 is provided with a pressing part 311. The sliding sleeve 31 has an unlocked position and a locked position in the vertical direction.
[0044] When the sliding sleeve 31 is in the unlocked position, the handlebar 1 is inserted into the vertical tube 2. When the slot 11 of the handlebar 1 is aligned with the movable body 32 in the horizontal direction, the sliding sleeve 31 slides vertically from the unlocked position to the locked position. The squeezing part 311 of the sliding sleeve 31 squeezes the movable body 32 to move laterally inward in the movable channel 21. The movable body 32 partially extends into the inner wall of the vertical tube 2 to engage with the slot 11 to form a snap-fit.
[0045] When installing the stem 1, the user first inserts it into the riser tube 2, then smoothly slides the stem 1 along the riser tube 2 until the slot 11 on the stem 1 aligns with the movable body 32. At this point, simply moving the sliding sleeve 31 from the unlocked position to the locked position applies a pressing force towards the inside of the riser tube 2 to the movable body 32 through the pressing part 311 on the inner side of the sliding sleeve 31. Under this pressing force, the movable body 32 gradually moves from the outside of the movable channel 21 to the inside of the movable channel 21 until it forms a tight engagement with the slot 11, thus creating a stable connection. At this point, the movable body 32 is partially located within the slot 11 and partially within the movable channel 21. Therefore, the stem 1 and the riser tube 2 are relatively fixed. This structure greatly simplifies the assembly process of the stem 1, eliminating the need for additional tools and providing great convenience for the user, making the assembly process of the stem 1 easier and faster.
[0046] In the embodiments of this application, the locking position of the sliding sleeve 31 is the position when the squeezing part 311 and the movable body 32 are aligned. There are no special restrictions on the specific position and number of unlocking positions. This means that any position where the sliding sleeve 31 is moved to where the squeezing part 311 and the movable body 32 are no longer aligned can be defined as the unlocking position.
[0047] In this embodiment, the movable channel 21 is tapered from the outside in. Specifically, the movable channel 21 forms a wide opening on one side of the outer wall of the vertical tube 2, while narrowing into a constricted opening on the inner wall of the vertical tube 2. This structure causes the bottom wall of the movable channel 21 to have an upwardly sloping structure that gradually slopes from the outside in. The movable body 32 can move freely between the constricted opening and the wide opening, thereby achieving a snap-fit state with the slot 11 and a disengaged state from the slot 11. It is worth noting that the opening size on the constricted side of the movable channel 21 should be smaller than the size of the movable body 32 to prevent the movable body 32 from falling off from the inside of the vertical tube 2.
[0048] Furthermore, to ensure that the movement of the movable body 32 within the movable channel 21 is both smooth and efficient, the movable body 32 is configured as a rolling element, which greatly reduces the frictional resistance during the movement of the movable body 32 and improves the overall mechanical performance. In this embodiment, the rolling element is preferably a ball bearing. Of course, the specific structure of the movable body 32 is not limited to this.
[0049] In this embodiment, the side of the extrusion part 311 facing the vertical tube 2 is set as an inclined surface, and the inclined surface is set to gradually tilt towards the vertical tube 2 in the direction from the locked position to the unlocked position.
[0050] Specifically, two configuration schemes are provided for the inclined surface on the extrusion section 311, as detailed below:
[0051] In the first embodiment, the inclined surface on the pressing part 311 is configured to gradually approach the side wall of the vertical tube 2 from top to bottom. This means that the locking position is above the unlocking position, and when installing and fixing the stem 1, the user needs to slide the sliding sleeve 31 from bottom to top. During this sliding process, the inclined surface will gradually apply a pressing force to the movable body 32, guiding it to move towards the inside of the movable channel 21 until the movable body 32 engages with the slot 11, thereby ensuring a stable connection between the stem 1 and the vertical tube 2.
[0052] In the second embodiment, the opposite structure is used. Specifically, the inclined surface on the pressing part 311 gradually moves away from the side wall of the vertical tube 2 from top to bottom. This means that the unlocking position is above the locking position. Therefore, when it is necessary to install and fix the stem 1, the operation steps should be reversed compared to the first method; the user needs to slide the sliding sleeve 31 from top to bottom. During this process, the inclined surface can also effectively apply pressing force to the movable body 32, gradually pushing the movable body 32 to the position where it engages with the slot 11, thus achieving a firm fixation between the stem 1 and the vertical tube 2.
[0053] When the movable body 32 is simultaneously engaged with both the vertical tube 2 and the slot 11, it should be partially located within the movable channel 21 and partially within the slot 11. When disassembly of the stem 1 is required, the user simply slides the sliding sleeve 31 from the locked position to the unlocked position, and the inclined surface on the pressing part 311 gradually moves away from the movable body 32. During this process, the movable body 32 smoothly leaves the slot 11 using the inclined structure of the movable channel 21 itself. It is worth noting that even when the sliding sleeve 31 is in the unlocked position, it still effectively blocks the movable body 32, ensuring its stability at the outer end of the movable channel 21 and preventing accidental detachment. With this structure, disassembly of the stem 1 requires no additional tools, greatly simplifying the disassembly process and making the assembly and disassembly of the stem 1 more efficient and easier.
[0054] In this embodiment, an unlocking limiter 4 and a locking limiter 5 are fixedly provided on the side wall of the vertical tube 2. The range of motion of the sliding sleeve 31 is limited between the unlocking limiter 4 and the locking limiter 5, ensuring its stability and safety during operation. When the sliding sleeve 31 slides to contact the locking limiter 5, the sliding sleeve 31 is in the locked position, at which time the stem 1 is firmly fixed; while when the sliding sleeve 31 slides to contact the unlocking limiter 4, the sliding sleeve 31 is in the unlocked position, providing convenience for the disassembly of the stem 1.
[0055] In this embodiment, the extrusion part 311 is annular and fixed to the circumferential inner wall of the sliding sleeve 31. In this application, the extrusion part 311 and the sliding sleeve 31 are an integral structure. Of course, this is not limiting. The extrusion part 311 can also be connected and fixed to the sliding sleeve 31 by welding, pasting or other means.
[0056] In this embodiment, a preferred design is one where the inclined surface of the compression part 311 gradually approaches the side wall of the vertical tube 2 from top to bottom. This design means that the locking position should be above the unlocking position. When the stem 1 needs to be fixed, the user should slide the sliding sleeve 31 upwards, and when the stem 1 needs to be disassembled, the sliding sleeve 31 should be slid downwards. Therefore, it can be understood that in this design, the locking limit member 5 should be above the unlocking limit member 4. Specifically, in this application, the locking limit member 5 is set as an upper limit ring, and the unlocking limit member 4 is set as a lower limit ring. Both the upper limit ring and the lower limit ring are sleeved inside the sliding sleeve 31. When the sliding sleeve 31 is in the locked position, the upper top surface of the pressing part 311 abuts against the lower bottom surface of the upper limit ring. The outer wall of the lower limit ring is fixed with a limit block 41. The bottom of the sliding sleeve 31 is provided with a limit groove 312 along its sliding direction. The limit block 41 is located in the limit groove 312. When the sliding sleeve 31 is in the unlocked position, the top wall of the limit groove 312 abuts against the top of the limit block 41.
[0057] Furthermore, a compression spring 33 is provided inside the sliding sleeve 31 to achieve automatic reset of the sliding sleeve 31. This ensures that the sliding sleeve 31 can be stably locked in the locked position when no external force is applied. In this application, the compression spring 33 is located inside the sliding sleeve 31 and sleeved on the outside of the vertical tube 2. Its top is in close contact with the bottom of the pressing part 311, while its bottom is in contact with the top of the unlocking limit member 4.
[0058] When the user applies a downward force to the sliding sleeve 31 to move it to the unlocked position, the movable body 32 can automatically move to the outside of the movable channel 21. At this time, the compression spring 33 is in a compressed state. When the slot 11 is aligned with the movable body 32, the user only needs to remove the force applied to the sliding sleeve 31, and the compression spring 33 can release its elastic potential energy, driving the sliding sleeve 31 to move to the locked position. Thus, the inclined surface of the pressing part 311 pushes the movable body 32 to a state of engagement with the slot 11, thereby fixing the handlebar 1 and the vertical tube 2.
[0059] In this embodiment of the application, the quick-install structure of the stem also includes a safety component 6 disposed on one side of the sliding sleeve 31. The safety component 6 can lock the sliding sleeve 31 in the locked position to prevent the sliding sleeve 31 from sliding accidentally during use, thereby providing safety for the stem 1 during daily use.
[0060] In this embodiment of the application, the insurance component 6 includes:
[0061] Mounting bracket 61 is fixed relative to the vertical tube 2. In this application, mounting bracket 61 is fixedly connected to the side wall of locking limit member 5. Of course, this is not restrictive. Mounting bracket 61 is also allowed to be fixedly connected to unlocking limit member 4 or the side wall of vertical tube 2.
[0062] A connecting plate 62 is disposed on one side of the vertical pipe 2 along the length direction of the vertical pipe 2. The connecting plate 62 can be fixedly connected to the mounting frame 61 or rotatably connected to the mounting frame 61. In this application, the connection method between the connecting plate 62 and the mounting frame 61 is preferably rotatably connected. The connecting plate 62 is provided with a through hole.
[0063] The safety nut 63 is embedded in the side wall of the sliding sleeve 31 and is fixedly connected to the sliding sleeve 31;
[0064] The safety bolt 64 passes through the through hole into the connecting plate 62 and is rotatably connected to the connecting plate 62.
[0065] During the use of the stem 1, the user can rotate the safety bolt 64, causing it to extend from the through hole and threadedly connect with the safety sleeve 63. This fixes the connecting plate 62 and the sliding sleeve 31 relatively, preventing the connecting plate 62 from moving along the length of the vertical tube 2. This locks the sliding sleeve 31 in the locked position, preventing further movement and improving the stability and safety of the stem 1 during use. When the user needs to readjust the sliding sleeve 31, simply rotate the safety bolt 64 again, causing it to retract from the safety sleeve 63 and return to the through hole.
[0066] The specific structure of the safety component 6 is not limited to this. The safety component 6 can also be a safety pin. The sliding sleeve 31 has a pin hole. The safety pin can be directly inserted into the pin hole to fix the connecting plate 62 and the sliding sleeve 31.
[0067] like Figure 3 and Figure 4 As shown in this embodiment, multiple slots 11 are provided along the length of the stem 1. By engaging the movable body 32 into slots 11 at different heights, the stem 1 and the vertical tube 2 can form fixed configurations at different heights. Therefore, this structure achieves the function of adjusting the height of the stem 1.
[0068] In this embodiment, the movable body 32 and the slot 11 can form multiple snap-fit connections in the circumferential direction of the riser 2 and the handlebar 1. Specifically, multiple movable bodies 32 are spaced apart along the circumferential sidewall of the riser 2, and the slot 11 can be configured as a ring-shaped slot 11, which is formed around the circumferential sidewall of the handlebar 1; multiple slots 11 can also be configured, with each slot corresponding to a multiple movable body 32. By providing multiple snap-fit connections between the riser 2 and the handlebar 1, the riser 2 and the handlebar 1 have good stability when fixed, thereby improving the safety of the handlebar 1 during use.
[0069] In this application embodiment, a bicycle is also provided, which includes any of the stem quick-mount structures described above.
[0070] Other embodiments of this application will readily conceive of by those skilled in the art upon consideration of the specification and practice of the embodiments thereof.
