Description

Technical Field

[0001] This utility model relates to the field of bicycle tires, specifically a convenient inflatable bicycle tire. Background Technology

[0002] A bicycle tire is a component mounted on the bicycle rim that directly contacts the ground. It mainly consists of an outer tire, an inner tube, and a valve. The inner tube is a ring-shaped, inflatable rubber tube. Its primary function is to provide the tire with elasticity and support through inflation, allowing the bicycle to ride smoothly on various road surfaces. When inflated, the inner tube fits tightly against the inner wall of the outer tire, providing support and cushioning vibrations. Currently, bicycle tires often require removing the threaded valve cap and connecting the end of an air pump to the valve for inflation, a relatively complex process. Therefore, a more conveniently inflatable bicycle tire is needed.

[0003] Existing bicycle tires are inconvenient to quickly remove the valve cap during use, which affects the efficiency of inflating the tires. Furthermore, the sealing performance of the valve caps on current bicycle tires is not good. Therefore, there is an urgent need for a bicycle tire that is easy to inflate. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a convenient inflatable bicycle tire to solve the problems of inconvenient quick removal of the valve cap and poor sealing performance at the valve in existing bicycle tires.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a convenient inflatable bicycle tire, including a bicycle inner tube, a valve stem fixedly connected to the outer wall of the inner tube, a slot provided inside the valve stem, a groove provided on the inner side wall of the slot, a cap installed on the outer wall of the valve stem, an insert fixedly connected to the inner wall of the cap, and a protrusion fixedly connected to one side of the insert.

[0006] A baffle is fixedly connected inside the valve stem, a sealing groove is formed inside the baffle, a sliding groove is formed inside the valve stem, a slider is movably connected inside the sliding groove, a return spring is fixedly connected to the bottom of the slider, a sealing plug is fixedly connected to the outer wall of the slider, and a sealing ring is fixedly connected to the top of the sealing plug.

[0007] Preferably, the valve stem forms a sliding structure with the insert block via a slot, and the insert block is symmetrically arranged with respect to the central axis of the cap.

[0008] Preferably, the protrusion is engaged with the valve stem via a slot, and the protrusion is elastically configured.

[0009] Preferably, the slider and the valve stem form a sliding structure through a groove, and the slider is symmetrically arranged with respect to the central axis of the sealing plug.

[0010] Preferably, the sealing ring is engaged with the baffle through a sealing groove, and the sealing ring and the sealing groove are compatible.

[0011] Preferably, the diameter of the sealing plug is smaller than that of the baffle, and the sealing plug is aligned with the central axis of the valve stem.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, through the setting of valve nozzle, slot, groove, cap, insert block and protrusion, allows the groove to squeeze the protrusion by pulling the cap, causing the protrusion to deform and release the limiting of the insert block, driving the insert block to slide along the slot, so that the cap can be removed from the valve nozzle, thereby facilitating the inflation of bicycle inner tubes.

[0014] 2. This utility model, through the setting of a sealing groove, a sliding groove, a slider, a return spring, a sealing plug, and a sealing ring, allows the slider to slide along the sliding groove under the action of the return spring and internal air pressure by disassembling the air clamp, thereby driving the sealing plug to return to its original position and allowing the sealing ring to engage and lock into the sealing groove, thus improving the sealing performance of the valve.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0022] The embodiments of this utility model will be described below based on its overall structure.

[0023] Please see Figure 1-5 A convenient inflatable bicycle tire includes a bicycle inner tube 1. A valve 2 is fixedly connected to the outer wall of the inner tube 1. A slot 3 is provided inside the valve 2. A groove 4 is provided on the inner side wall of the slot 3. A cap 5 is installed on the outer wall of the valve 2. An insert 6 is fixedly connected to the inner wall of the cap 5. A protrusion 7 is fixedly connected to one side of the insert 6. The valve 2 and the insert 6 form a sliding structure through the slot 3. The insert 6 is symmetrically arranged about the central axis of the cap 5. The protrusion 7 is engaged with the valve 2 through the groove 4. The protrusion 7 is elastic and can be easily removed from the cap 5, thereby facilitating the inflation of the bicycle tire.

[0024] Please see Figure 1-5 A convenient inflatable bicycle tire is provided. A baffle 8 is fixedly connected inside the valve 2. A sealing groove 9 is opened inside the baffle 8. A sliding groove 10 is opened inside the valve 2. A slider 11 is movably connected inside the sliding groove 10. A return spring 12 is fixedly connected to the bottom of the slider 11. A sealing plug 13 is fixedly connected to the outer wall of the slider 11. A sealing ring 14 is fixedly connected to the top of the sealing plug 13. The slider 11 and the valve 2 form a sliding structure through the sliding groove 10. The slider 11 is symmetrically arranged with the central axis of the sealing plug 13. The sealing ring 14 is engaged with the baffle 8 through the sealing groove 9. The sealing ring 14 is adapted to the sealing groove 9. The diameter of the sealing plug 13 is smaller than that of the baffle 8. The sealing plug 13 is aligned with the central axis of the valve 2, which can improve the sealing performance of the valve 2.

[0025] Working principle: During use, pulling the cap 5 causes the slot 4 to press against the protrusion 7, causing the protrusion 7 to deform and release the limiting position on the insert 6. This causes the insert 6 to slide along the slot 3, allowing the cap 5 to be removed from the valve 2. By clamping the air clamp at one end of the air pump onto the outer wall of the valve 2, the push rod inside the air clamp can press against the sealing plug 13, causing the sealing plug 13 to move. This moves the slider 11 along the slide groove 10, causing the sealing ring 14 to move out of the sealing groove 9. When the air pump starts pumping air... When the air is pumped, it can enter the valve 2 through the gap between the baffle 8 and the sealing plug 13 and flow into the inner tube 1 of the bicycle. After the air is pumped, the air clamp is removed. Under the action of the return spring 12 and the internal air pressure, the slider 11 can slide along the slide groove 10, which drives the sealing plug 13 to return to its original position. This allows the sealing ring 14 to engage with the sealing groove 9 and seal the valve 2. This completes the use of the device. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
