Abstract
The utility model discloses a tubeless valve of a bicycle. Based on the Presta valve of the existing bicycle, a valve seat is made from rubber material, and a metal sheet is arranged in the valve seat. The mounting fastening force is compressed on a rim through the built-in metal sheet and the rubber layer; and the pressed valve seat generates corresponding deformation according to the rim radian and clings to the rim surface to realize a sealing effect.
Description
Technical field
The utility model relates to the device that a kind of tire charges and discharges gas and can keep pressing in it, and particularly bicycle tubeless wheels charge and discharge gas.
Background technique
Bicycle tubeless wheels are of a great variety at present, and different model rim wheel rim curvature differs greatly, the just normally sealing of special-purpose valve cock that needs installation mouth seat and wheel rim curved surface to be complementary.Existing bicycle tubeless wheels valve cock is not had a versatility have been increased cost of production and has also made troubles to maintenance.
Summary of the invention
[0003] the utility model provides a kind of universal valve cock that is applicable to all kinds of bicycle tubeless wheels.It is the structure that on existing bicycle French valve cock basis, has improved the mouth seat: it is characterized in that contacting the mouth seat of realizing sealing with wheel rim adopts rubber material to process; At the built-in tinsel of rubber mouth seat; Valve cock during through mouth seat and the fastening installation of wheel rim built-in metal sheet and rubber base corresponding deformation takes place according to the rim surface different curve, mouth seat sealing position is closely withheld all the time on the rim wheel rim, realizes sealing.This soft outside but hard inside structure can both reliable sealing on the rim wheel rim of Any shape.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is the utility model sectional drawing.
Fig. 2 is that the utility model is installed in schematic representation on the rim.
Fig. 3 is that the built-in metal sheet is prefabricated into the butterfly schematic representation in the practical implementation.
1 valve cock cylindrical shell among the figure, 2 mouth seats, 3 tinsels, 4 tightening nuts, 5 valve insides, the protruding circle of 6 cylindrical shells, 7 rim wheel rims.
Embodiment
The cylindrical shell 1 of the utility model valve cock, tightening nut 4 and valve inside 5 are identical with standard bicycle French valve cock structure, it is characterized in that on bicycle French valve cock basis, having improved the mouth seat.Existing bicycle tubeless valve cock install the mouth seat usually by metallic material or hard plastic according to prefabricated the forming of rim wheel rim curved surface radian of being installed; This hard mouth seat surface of contact shape can not change with the rim surface radian is different, therefore can only be installed on the specific rim.Mouth seat that the utility model links to each other with valve cock cylindrical shell 12 is processed by rubber, and the rubber better elastic very easily changes and is out of shape along with the rim wheel rim that is in contact with it 7 curved surface radians, can tightly be attached on the surface of contact of different radians.In order to add the sealing reliability between seat 2 and the wheel rim 7 of replying defiantly, at the built-in tinsel 3 of mouth seat 2 rubber.Tightening nut 4 pressure act on the built-in metal sheet 3 through valve cock cylindrical shell 1 and the protruding circle 6 of cylindrical shell, and final the generation and the similar distortion of wheel rim 7 curved surfaces in the stressed back of tinsel 3 guarantees that rubber mouth seat is pressed on the surface of contact of different radians can both realize reliable sealing.
In the practical implementation, can the tinsel precompressed be become butterfly as shown in Figure 3, make it more be prone to produce the deformation trend that adapts to the wheel rim curved surface.The tinsel diameter of bore also links closely less than the protruding circle external diameter of valve cock barrel tip each other.
Claims (3)
1. bicycle tubeless valve cock, it is characterized in that: the mouth seat (2) that links to each other with valve cock cylindrical shell (1) is processed by rubber material.
2. bicycle tubeless valve cock according to claim 1 is characterized in that: the built-in tinsel of valve cock rubber mouth seat (2) (3).
3. bicycle tubeless valve cock according to claim 1 and 2; It is characterized in that: the valve cock barrel tip has protruding circle (6); Tinsel (3) diameter of bore also links closely less than the protruding circle of valve barrel tip (6) external diameter each other, and tinsel (3) is wrapped up by rubber mouth seat (2) fully.
