Description

Technical Field

[0001] This utility model relates to the field of bicycle seat technology, and in particular to a bicycle seat that is easy to disassemble. Background Technology

[0002] Bicycle saddles are a common bicycle accessory. Typically, different styles, models, or structures of bicycle saddles are designed to meet the needs of users, taking into account their different usage habits, the characteristics of the bicycle, or the user's own body shape.

[0003] Currently, bicycle saddles are usually fixed by clamps or bolts when being replaced or adjusted. However, the saddle is usually connected to the seatpost as a whole, which makes it difficult to disassemble the saddle from the seatpost. This results in poor practicality and the inability to adjust the horizontal angle of the saddle after installation. Consequently, the saddle cannot be connected and adjusted according to the user's needs, resulting in poor flexibility. Utility Model Content

[0004] This invention provides a bicycle seat that is easy to disassemble, solving the problems in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bicycle seat that is easy to disassemble includes a mounting base and a seat plate fixedly connected to the surface of the mounting base. The bottom end of the mounting base is fixedly connected to a post, and a connecting tube is inserted into the bottom of the post. A seat tube is rotatably connected to the bottom of the connecting tube.

[0007] Two limiting rods are inserted through the inside of the connecting cylinder. A return spring is sleeved on the outside of the limiting rod and is located on the outer wall of the connecting cylinder. A pull block is fixedly connected to the outer end of the return spring and is fixedly connected to the outer end of the limiting rod.

[0008] The end of the limiting rod away from the pull block is a wedge-shaped part, and an insert post is attached to the outside of the wedge-shaped part;

[0009] The middle outer wall of the insertion post is provided with an annular groove that can accommodate the insertion of the limiting rod. The annular groove has a "U" shaped structure, and the bottom outer wall of the insertion post is provided with a wedge-shaped end that fits with the wedge-shaped part.

[0010] Using the above structure, the mounting base is inserted into the connecting cylinder through the bottom post. A wedge-shaped end is provided at the bottom of the post. The wedge-shaped end, in contact with the wedge-shaped portion of the limiting rod, causes the post to press against the wedge-shaped portions on both sides, thus causing the limiting rod to press the return spring outwards. Simultaneously, a U-shaped annular groove is provided on the outer wall of the post. When the annular groove moves to one side, the limiting rod limits its position, allowing the limiting rod to install the post inside the connecting cylinder through the annular groove. This enables the mounting base to quickly install the seat cushion above the connecting cylinder. To adjust the horizontal angle of the seat cushion, the operating part rotates the worm gear. The rotation of the worm gear above the seat tube causes the worm wheel to rotate, which in turn rotates the connecting cylinder horizontally above the seat tube. This causes the connecting cylinder to rotate the entire seat cushion, allowing for flexible adjustment and removal of the seat cushion.

[0011] The insert has an "I" shaped structure, and the central axis of the insert coincides with the central axis of the connecting cylinder.

[0012] By adopting the above structure, the "I"-shaped structure of the insert post allows for stable insertion inside the connecting cylinder and stable positioning outside the limiting rod. This ensures the insertion and installation effect of the insert post driving the mounting base above the connecting cylinder, facilitates stable installation of the mounting base driving the seat plate, and is simple to operate and easy to install.

[0013] The top of the connecting cylinder has two grooves corresponding to the two limiting rods, and the two grooves are symmetrically arranged about the central axis of the connecting cylinder.

[0014] The inner wall of each groove is movably fitted with a positioning block, and the positioning block is fixedly connected to the outer wall of the top end of the insertion post.

[0015] By adopting the above structure, the groove and positioning block allow the mounting base to accurately insert the plug into the connecting cylinder through the positioning connection of the groove and positioning block. This achieves the stability and convenience of the installation of the plug and the connecting cylinder. Moreover, the groove and positioning block increase the contact area between the plug and the connecting cylinder, which helps to increase the installation firmness between the plug and the connecting cylinder.

[0016] A worm gear is fixedly connected to the outer wall of the connecting cylinder, and a worm is meshed with the outer wall of the worm gear. The worm is rotatably connected to the top of the seat tube, and an operating part is fixedly connected to the outer end of the worm.

[0017] With the above structure, the worm gear and worm are meshed together. The worm rotates at the top of the seat post, allowing the user to rotate it above the seat post via the operating mechanism. This facilitates precise rotation of the worm gear driven by the worm. The worm gear, fixed to the bottom outer wall of the connecting cylinder, allows the connecting cylinder above the seat post to adjust the saddle's horizontal angle. This allows the saddle to meet different user needs, improving the flexibility of the bicycle saddle. Compared to existing single height adjustment, this achieves precise multi-axis position adjustment. Furthermore, the worm gear and worm wheel drive ensures the accuracy and stability of the connecting cylinder's rotation, guaranteeing the saddle's rotation quality and effect.

[0018] The top end of the seat tube is fixedly connected to a "T"-shaped part, and the "T"-shaped part is rotatably connected to the inner wall of the connecting cylinder.

[0019] With the above structure, the "T" shaped part enables stable rotation between the seat post and the connecting cylinder, facilitating stable rotation of the connecting cylinder above the seat post. This ensures the connection between the seat post and the connecting cylinder and helps extend the overall service life of the bicycle saddle.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0021] In this invention, the mounting base uses a positioning block and a groove to stably insert the plug into the inside of the connecting cylinder. Under the action of the limiting rod and the annular groove, the mounting base ensures the installation effect of the seat plate above the connecting cylinder. Moreover, the setting of the return spring and the pull block facilitates the user's disassembly, assembly, and maintenance of the seat plate, greatly improving the flexibility of bicycle seat use. Furthermore, the worm gear drives the horizontal adjustment of the connecting cylinder above the seat tube, ensuring the rotation quality and effect of the seat plate, and achieving precise adjustment of the horizontal position of the seat plate.

[0029] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1-5 A removable bicycle seat includes a mounting base 1 and a seat plate 2 fixedly connected to the surface of the mounting base 1. A post 3 is fixedly connected to the bottom end of the mounting base 1, and a connecting cylinder 4 is inserted into the bottom of the post 3. The post 3 has an "I"-shaped structure, and its central axis coincides with the central axis of the connecting cylinder 4. The "I"-shaped structure of the post 3 allows for stable insertion inside the connecting cylinder 4. Specifically, two limiting rods 8 are inserted through the connecting cylinder 4, providing stable positioning on the outside of the limiting rods 8. This ensures the insertion and installation effect of the post 3 driving the mounting base 1 above the connecting cylinder 4, facilitating stable installation of the seat plate 2 by the mounting base 1. The design is simple to operate and easy to install. Furthermore, to achieve the desired insertion position... The precise insertion of the connecting cylinder 4 is achieved by having two grooves 11 corresponding to the two limiting rods 8 at the top of the connecting cylinder 4. The two grooves 11 are symmetrically arranged about the central axis of the connecting cylinder 4. At the same time, a positioning block 12 is movably inserted into the inner wall of each groove 11, and the positioning block 12 is fixedly connected to the outer wall of the top of the insertion post 3. Through the arrangement of the grooves 11 and the positioning blocks 12, the mounting base 1 can precisely insert the insertion post 3 into the connecting cylinder 4 through the positioning connection of the grooves 11 and the positioning blocks 12, thus achieving the installation stability and convenience of the insertion post 3 and the connecting cylinder 4. Moreover, the arrangement of the grooves 11 and the positioning blocks 12 increases the contact area between the insertion post 3 and the connecting cylinder 4, which helps to increase the installation firmness between the insertion post 3 and the connecting cylinder 4.

[0031] To achieve stable insertion and limiting of the plug 3 and the connecting cylinder 4, a return spring 9 is sleeved on the outside of the limiting rod 8, and the return spring 9 is located on the outer wall of the connecting cylinder 4. A pull block 10 is fixedly connected to the outer end of the return spring 9, and the pull block 10 is fixedly connected to the outer end of the limiting rod 8. The end of the limiting rod 8 away from the pull block 10 is a wedge-shaped part, and the plug 3 is attached to the outside of the wedge-shaped part. At the same time, an annular groove is opened on the outer wall of the middle part of the plug 3 to accommodate the insertion of the limiting rod 8. The annular groove has a "U" shape structure, and a wedge-shaped end is opened on the outer wall of the bottom end of the plug 3 to fit with the wedge-shaped part. By opening the "U"-shaped annular groove on the outer wall of the plug 3, the limiting rod 8 will limit the position of the annular groove when it moves to one side, so that the limiting rod 8 installs the plug 3 inside the connecting cylinder 4 through the annular groove, ensuring the insertion stability of the plug 3 inside the connecting cylinder 4.

[0032] Furthermore, a seat tube 5 is rotatably connected to the lower part of the connecting cylinder 4. Specifically, a "T"-shaped part is fixedly connected to the top end of the seat tube 5, and the "T"-shaped part is rotatably connected to the inner wall of the connecting cylinder 4. Under the action of the "T"-shaped part, the seat tube 5 and the connecting cylinder 4 can rotate stably, facilitating the stable rotation of the connecting cylinder 4 above the seat tube 5. This ensures the connection effect between the seat tube 5 and the connecting cylinder 4, and helps to extend the overall service life of the bicycle saddle. At the same time, in order to realize the rotation drive of the connecting cylinder 4 on the surface of the seat tube 5, a worm gear 6 is fixedly connected to the outer wall of the connecting cylinder 4. A worm 7 is meshed with the outer wall of the worm gear 6. The worm 7 is rotatably connected to the top end of the seat tube 5, and an operating device is fixedly connected to the outer end of the worm 7. The operating mechanism, through this configuration, connects the worm gear 6 and the worm 7. With the worm 7 rotating at the top of the seat tube 5, the user can rotate the worm 7 above the seat tube 5 via the operating mechanism. This facilitates precise rotation of the worm gear 6 by the worm 7. The worm gear 6 is fixed to the bottom outer wall of the connecting cylinder 4, allowing the connecting cylinder 4 above the seat tube 5 to adjust the horizontal angle of the saddle 2. This allows the saddle 2 to meet different user needs, improving the flexibility of the bicycle saddle. Furthermore, the meshing drive of the worm 7 and worm gear 6 ensures the precision and stability of the rotation of the connecting cylinder 4 driven by the worm 7, guaranteeing the rotation quality and effect of the saddle 2.

[0033] Working principle: During operation, the seat post 5 is installed to the bicycle frame, ensuring the stability of the seat post 5 position. The mounting base 1 is inserted into the connecting cylinder 4 via the bottom insert post 3 through the positioning block 12 and groove 11. A wedge-shaped end is provided at the bottom of the insert post 3. The wedge-shaped end, in contact with the wedge-shaped portion of the limiting rod 8, causes the insert post 3 to press against the wedge-shaped portions on both sides from above. This causes the limiting rod 8 to press the return spring 9 outward. Simultaneously, a U-shaped annular groove is provided on the outer wall of the insert post 3. When the annular groove moves to one side, it is limited by the limiting rod 8. This allows the limiting rod 8 to install the insert post 3 inside the connecting cylinder 4 through the annular groove, achieving rapid installation of the mounting base 1 and the seat pad 2 above the connecting cylinder 4. This process is designed to facilitate the installation of the seat pad. The horizontal angle of the seat plate 2 is adjusted by rotating the worm gear 7 through the operating part. Under the rotation of the worm gear 7 above the seat tube 5, the worm gear 7 drives the worm wheel 6 to rotate, which in turn drives the internal connecting cylinder 4 to rotate horizontally above the seat tube 5. This causes the connecting cylinder 4 to rotate the entire seat plate 2 above, thus achieving flexible adjustment of the seat plate 2. When disassembling the seat plate 2, the pull block 10 drives the limiting rod 8 to move outward, which stretches the return spring 9. This prevents the limiting rod 8 from being limited by the annular groove, making it easier for the insert 3 to be pulled out from inside the connecting cylinder 4. This facilitates quick disassembly of the seat plate 2 by the user, making it easier to maintain and replace the seat, and improving the flexibility of the bicycle seat. This completes the working principle of the bicycle seat.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
