Abstract
The utility model relates to a self-closing valve for a bicycle tyre, comprising a valve inside, a locking nut (6) and a valve seat (7). The self-closing valve for a bicycle tyre is mainly characterized in that the valve inside mainly comprises a valve body (1), a valve rod (2) which can be moved axially in the valve body (1), an outside sealing ring which is sheathed at the outside layer of the valve body (1), and an inside sealing circular plate (4) which is installed on the valve rod (2). A locking lug boss (5) is arranged on the valve body (1), and the guiding hole of the valve rod is arranged in a passage in the valve body. The valve body (1) is connected with the valve seat (7) by the locking nut (6). The self-closing valve for a bicycle tyre has the advantages of simple structure, reliable seal, long service life, low cost, strong adaptability, etc.
Description
The utility model belongs to a kind of Component of bicycle, is specifically related to the improvement of bicycle tyre valve mouth.
Existing bicycle valve cock mostly adds the close gas of rubber tube by the metallic conduit with air vent, and rubber tube is worked under the expansion situation, and air pressure is high more, and it is easy more to leak gas.And the rubber tube of this valve inside easily tired, follow the string or break, can't avoid natural leak.
The purpose of this utility model is to overcome shortcoming of the prior art, and a kind of close gas and good reliability are provided, long service life, suitable self-closing bicycle valve cock simple in structure.
The technical solution of the utility model and concrete structure accompanying drawings enumeration are as follows:
Fig. 1 is a positive view of the present utility model.
Fig. 2 is that the A of Fig. 1 is to view.
As shown in Figure 1, the utility model comprises valve inside, lock nut (6), valve seating (7), described valve inside mainly by valve body (1), can be in valve body (1) axially movable valve rod (2), be placed in the outer field exterior seal ring of valve body (1) (3) and the interior sealing plectane (4) that is loaded on the valve rod (2) forms, be provided with locking boss (5) on the described valve body (1), be provided with the stem guiding hole on its internal channel, valve body (1) is connected with valve seating (7) by locking nut (6). In order to prevent that dust from entering in the valve body, can add a cover dust cap (8) at the air inlet end of valve body (1). In addition, have bleeder port (9) in the outlet side of valve body (1). Operation principle of the present utility model is as follows: when need during to tyre inflating, compressed air enters the internal channel of valve body (1) through the air inlet end of valve body (1), interior sealing plectane (4) is washed open, and air enters in the tire through pilot hole, valve body gas outlet end, valve seating (7). Fill Gas is complete, and the pressure air in the tire acts on the interior sealing plectane (4), promotes valve rod (2) to the air inlet end motion, until interior sealing plectane (4) seals pilot hole. Air pressure in the tire is more big, and the sealing effectiveness of interior sealing plectane (4) is more remarkable.
The utlity model has the advantages such as simple in structure, that sealing is reliable, durable, the air storage time is long, cost is low, applicability is strong, it both can make bicycle inflating valve, also can make the valve cock of the tire of motorcycle, tricycle.
