Technical Field

[0001] This utility model relates to the field of tire valve cap technology, and in particular to a bicycle tire valve cap with positioning function. Background Technology

[0002] A bicycle tire valve cap is used to cover the inner tube of a bicycle tire to prevent dust, dirt, and moisture from entering the valve, thereby avoiding damage to the valve core or affecting the seal during inflation.

[0003] Chinese Patent Publication No. CN2535256Y, published on 20030212, discloses a tire valve safety cap, which consists of an outer casing and a valve cap. Since it is composed of an outer casing and a valve cap with anti-detachment teeth, a driving block and a driven block are respectively provided inside the outer casing and the valve cap. Therefore, when the two are combined, the driving block and the driven block are engaged. When the outer casing is rotated clockwise, the driving block inside the outer casing drives the driven block inside the valve cap to lock the cap on the tire valve.

[0004] The existing bicycle tire valve caps mentioned above are mostly simple cover structures that are attached to the valve on the tire by screwing. In actual implementation, the functionality of the valve cap can be further expanded. Therefore, there is an urgent need to propose a bicycle tire valve cap with a positioning function to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a bicycle tire valve cap with positioning function in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A bicycle tire valve cap with positioning function includes a valve cap tube and a positioning device. A top seat is fixedly connected to the top of the valve cap tube, and an internal thread is formed on the inner surface of the valve cap tube. A top sleeve is fixedly connected to the top of the top seat. The top sleeve and the valve cap tube form a placement cavity for placing the positioning device.

[0008] Preferably, the outer side of the cap tube is provided with a protrusion and a fixing part for fixing the protrusion to the bicycle wheel hub. A connecting sleeve is rotatably connected to the outer wall of the protrusion. A crossbar and an elastic part for maintaining the position of the crossbar are integrated on the top of the connecting sleeve. The bottom of the crossbar abuts against the top of the top sleeve.

[0009] Preferably, the outer wall of the horizontal bar is engaged with the top of the top sleeve via a slot.

[0010] Preferably, the fixing part includes a coupling seat fixedly connected to the protrusion, and the bottom of the coupling seat is provided with an adhesive layer.

[0011] Preferably, the elastic part includes a slide bar that is slidably connected to the inner surface of the top of the connecting sleeve, the top of the slide bar being fixedly connected to the bottom of the crossbar, and a spring being fixedly connected between the bottom of the slide bar and the inner surface of the connecting sleeve.

[0012] Preferably, a protrusion is fixedly connected to the bottom of the slide bar, and the outer wall of the protrusion is slidably connected to the inner wall of the connecting sleeve through a vertically arranged slide groove.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. In this application, the locator is placed on the top seat, and the top sleeve is fitted onto the top of the locator, so that the top sleeve is fixed to the top seat. Then, the valve cap is screwed onto the outer wall of the valve on the tire, thereby realizing the combination of the valve cap and the bicycle tire valve. By adding a locator, the functionality of the valve cap is expanded, allowing the owner to determine the position of the bicycle according to the locator, improving the safety performance of the bicycle, and thus improving the use effect of the bicycle tire valve cap.

[0015] 2. In this application, the protrusion is fixed to the bicycle wheel hub with adhesive. During the assembly and disassembly of the valve cap, the crossbar is placed horizontally on the outside of the valve cap. After the valve cap is tightened, the crossbar is pulled to make the slide bar slide into the connecting sleeve, and the spring is stretched. Then, the crossbar drives the fixing sleeve to deflect until the crossbar is mounted on the top of the top sleeve. The crossbar is released, and the spring pulls the slide bar and the crossbar. The crossbar engages with the top of the top sleeve through the slot. The crossbar provides vertical constraint force to the valve cap, effectively preventing the spiral connection between the valve cap and the valve from loosening, thereby improving the stability of the bicycle tire valve cap with positioning function.

[0023] Please refer to Figures 1-4. This utility model provides a technical solution:

[0024] A bicycle tire valve cap with positioning function includes a valve cap tube 2 and a positioner 10. A top seat 9 is fixedly connected to the top of the valve cap tube 2, and an internal thread is provided on the inner surface wall of the valve cap tube 2. A top sleeve 1 is fixedly connected to the top of the top seat 9. The top sleeve 1 and the valve cap tube 2 form a placement cavity for placing the positioner 10.

[0025] Positioner 10 is placed on top seat 9, and top sleeve 1 is fitted onto top of positioner 10, fixing top sleeve 1 to top seat 9. Then, valve cap 2 is screwed onto the outer wall of valve on tire, thus combining valve cap with bicycle tire valve. By adding positioner 10, the functionality of valve cap is expanded, allowing the owner to determine the position of bicycle based on positioner 10, improving bicycle safety and thus enhancing the effectiveness of bicycle tire valve cap.

[0026] It should be noted that the locator 10 used here is an Air Tag, which is already fully disclosed in the existing technology, and its specific working mechanism will not be described in detail here.

[0027] Specifically, such as Figure 2 and Figure 4As shown, the outer side of the mouthpiece 2 is provided with a protrusion 6 and a fixing part for fixing the protrusion 6 to the bicycle wheel hub. A connecting sleeve 7 is rotatably connected to the outer wall of the protrusion 6. The top of the connecting sleeve 7 integrates a crossbar 3 and an elastic part for maintaining the position of the crossbar 3. The bottom of the crossbar 3 abuts against the top of the top sleeve 1. The connecting seat 5 is fixed to the bicycle wheel hub by adhesive. During the assembly and disassembly of the mouthpiece 2, the crossbar 3 will be placed horizontally on the outside of the mouthpiece 2. After the mouthpiece 2 is tightened, the crossbar 3 is pulled to make the slider 8 slide with the connecting sleeve 7. The spring 12 is stretched. Then, the connecting sleeve 7 is deflected by the crossbar 3 until the crossbar 3 is placed on the top of the top sleeve 1. The crossbar 3 is released, and the spring 12 pulls the slider 8 and the crossbar 3. The crossbar 3 is engaged with the top of the top sleeve 1 through the slot 4. The crossbar 3 is used to fix the mouthpiece 2. Providing vertical constraint effectively prevents the spiral connection between the valve cap 2 and the valve from loosening, thereby improving the stability of the bicycle tire valve cap with positioning function.

[0028] Specifically, such as Figure 2 and Figure 3 As shown, the outer wall of the horizontal bar 3 engages with the top of the top sleeve 1 via the slot 4, thereby ensuring the stability of the connection between the horizontal bar 3 and the top sleeve 1. The fixing part includes a connecting seat 5 fixedly connected to the protrusion 6, and an adhesive layer is provided at the bottom of the connecting seat 5 to fix the connecting seat 5 to the bicycle wheel hub. The elastic part includes a slide bar 8 slidably connected to the inner wall of the top of the connecting sleeve 7. The top of the slide bar 8 is fixedly connected to the bottom of the horizontal bar 3, and a spring 12 is fixedly connected between the bottom of the slide bar 8 and the inner wall of the connecting sleeve 7 to maintain the vertical stability of the horizontal bar 3 and provide the horizontal bar 3 with the characteristic of vertical movement. A protrusion 11 is fixedly connected to the bottom of the slide bar 8. The outer wall of the protrusion 11 is slidably connected to the inner wall of the connecting sleeve 7 via a vertically set sliding groove, thereby preventing the slide bar 8 from completely detaching from the connecting sleeve 7.

[0029] Working principle: The locator 10 is placed on the top seat 9, and the top sleeve 1 is fitted onto the top of the locator 10, fixing the top sleeve 1 to the top seat 9. Then, the valve cap 2 is screwed onto the outer wall of the tire valve, thus connecting the valve cap to the bicycle tire valve. The addition of the locator 10 expands the functionality of the valve cap, allowing the rider to determine the bicycle's position, improving bicycle safety and the overall effectiveness of the bicycle tire valve cap. The connecting seat 5 is fixed to the bicycle rim with adhesive. During the installation and removal of the valve cap 2, the crossbar 3 lies horizontally on the outside of the valve cap 2. After tightening the valve cap 2, pulling the crossbar 3 causes the slide bar 8 to slide against the connecting sleeve 7, stretching the spring 12. The crossbar 3 then drives the connecting sleeve 7 to deflect until the crossbar 3 is positioned on top of the top sleeve 1. Releasing the crossbar 3 releases the spring 12. Pull the slider 8 and the horizontal bar 3 together. The horizontal bar 3 engages with the top of the top sleeve 1 through the slot 4. The horizontal bar 3 provides a vertical constraint force to the valve cap 2, effectively preventing the spiral connection between the valve cap 2 and the valve from loosening, thereby improving the stability of the bicycle tire valve cap with positioning function.
