Abstract
The utility model relates to a valve needle, particularly a valve needle for a bicycle tyre. The utility model is composed of a needle mouth, a needle head, an air plug arranged in the needle head amd an air inlet arranged on the wall of the needle head. The inner wall of the needle head is in the shape of a neck bottle, the air plug is cleaved to the inner wall of the needle head, and the shape of the top part of the air plug is tightly matched with the neck part of the needle head. The utility model has the advantages of simple structure, good sealing effect and long service life.
Description
The utility model relates to a kind of plunger, particularly a kind of bicycle tyre plunger.
Existing bicycle tyre with the defective of plunger is: the vent plug of syringe needle inside is cylindrical, and it and syringe needle inwall can not be close to, and the surface of contact size of vent plug top and needle tip, causes sealability relatively poor, produces gas leak phenomenon.Inlet hole on the pinhead wall is less than normal in addition, and air inlet is not smooth.
The purpose of this utility model just is to overcome above-mentioned the deficiencies in the prior art, and a kind of bicycle tyre plunger of good seal performance is provided.
As above design, the technical solution of the utility model are:
A kind of bicycle tyre plunger, by pin mouth, syringe needle, place vent plug in the syringe needle and the inlet hole on the pinhead wall to form, it is characterized in that: the syringe needle inwall is the neck ampuliform, vent plug is close to the syringe needle inwall, and its top shape can with syringe needle neck drive fit.
The neck of described syringe needle can be cone table shape, and placing the vent plug in it is taper type.
The neck of described syringe needle be "
" shape, placing the vent plug in it is " protruding " font.
Described inlet hole can be square hole, also can be rhombus.
The utility model has the advantages that: simple in structure, good sealing effect, long service life.
The utility model will be further described below in conjunction with drawings and Examples.
Fig. 1 is a sectional drawing of the present utility model.
Fig. 2 is the sectional drawing of the another kind of mode of the utility model.
As shown in the figure, a kind of bicycle tyre plunger, by pin mouth 1, syringe needle 2, place the vent plug 3 in the syringe needle and the inlet hole 4 of square hole on the pinhead wall or rhombus to form, the syringe needle inwall is the neck ampuliform, vent plug is close on the syringe needle inwall, and its top 5 can with syringe needle neck 6 drive fits.The syringe needle neck can be cone table shape, and placing the vent plug in it is taper type (as shown in Figure 1).The neck of syringe needle also can be "
Shape, placing the vent plug in it is " protruding " font (as shown in Figure 2).This plunger is after tire is pumped enough air in, and its air pressure inside acts on the vent plug bottom, promotes vent plug and moves upward, and the top of vent plug can be sticked together with the syringe needle inwall tightly, may thereby significantly reduced gas leakage.
Claims (4)
