Abstract
The utility model discloses an improvement structure of a tyre inflating valve, which consists of an inflating valve body and an inflating valve base arranged at the lower end of the inflating valve body. The inflating valve base is sleeved, stuck and fixed in the air vent seat of an inner tyre. The joint face of the base lower end plane of the inflating valve base and the air vent seat of the inner tyre is provided with the joint face of a circular flange and a groove. Because the joint face of the base lower end plane of the inflating valve base and the air vent seat of the inner tyre is provided with the joint face of the circular flange and the groove additionally; consequently, the joint face of the base of the inflating valve base and the air vent seat of the inner tyre is increased. After the joint face of the circular flange and the groove is sulfurized, the rubber enters and produces reaction bonding. The tensile force of the finished product is increased; a tail hole hardly comes unglued; and the gravitation force and the tensile force are increased.
Description
Technical field
The utility model relates to a kind of tire, particularly relates to a kind of improvement structure of tire valve.
Background technology
As shown in Figure 1, the tire valve of commonly using is made up of Valve tip body 1 ' and the valve base 2 ' that is fixed in Valve tip body 1 ' lower end.Existing valve base 2 ' is the plane, is prone to the uropore place during use and comes unstuck, and the undesirable condition that tire tube valve is directly pulled up from the inner tube of a tyre 3 ' often occurs, and particularly when tire pressure was not enough, the easier tire tube valve that occurs was pulled out phenomenon.
The utility model content
The purpose of this utility model is to provide a kind of improvement structure of tire valve more closely that combines with the inner tube of a tyre.
For achieving the above object, technical solution of the present utility model is:
The utility model is a kind of improvement structure of tire valve, and it is made up of Valve tip body and the valve base that is fixed in the Valve tip body lower end, and valve base is nested with and is pasted and fixed in the pore seat of the inner tube of a tyre; The faying face of the base lower surface of described valve base and inner tube of a tyre pore seat is provided with the faying face of an annular lip and groove.
The base lower surface of described valve base is provided with an annular groove, be provided with an annular lip on inner tube of a tyre pore seat, the annular lip on the described inner tube of a tyre pore seat can be connected in the annular groove of valve base base lower surface and by viscose glue and bond together.
The base lower surface of described valve base is provided with an annular lip, be provided with an annular groove on inner tube of a tyre pore seat, the annular lip of described valve base base lower surface can be connected in the annular groove on the inner tube of a tyre pore seat and by viscose glue and bond together.
Annular groove on the base lower surface of described valve base is a semicircular arc, and the annular lip on inner tube of a tyre pore seat is a semicircular arc.
After adopting such scheme, owing to set up the faying face of an annular lip and groove on the base lower surface of valve base of the present utility model and the faying face of inner tube of a tyre pore seat, thereby increased the faying face of valve base and inner tube of a tyre pore seat, bond area can increase by 10%.It is bonding that the faying face of this annular lip and groove rubber behind over cure enters and produce reaction, increased the pulling force of finished product, makes that uropore is difficult for coming unstuck, and the power that is pulled increases, and the single-piece pulling force can increase more than 15%.In addition, the substance of brass reduces, and has saved raw MAT'L.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is the tire valve cutaway view of commonly using;
Fig. 2 is a cutaway view of the present utility model;
Fig. 3 is the lower surface figure of the utility model valve base.
The specific embodiment
As shown in Figure 2, the utility model is a kind of improvement structure of tire valve, and it is made up of Valve tip body 1 and the valve base 2 that is fixed in Valve tip body 1 lower end.Valve base 2 is nested with and is pasted and fixed in the pore seat 31 of the inner tube of a tyre 3.
The base lower surface 21 of described valve base 2 is provided with an annular groove 22 (as shown in Figure 3), be provided with an annular lip 32 on the inner tube of a tyre 3 pore seats 31, the annular lip 32 on the described inner tube of a tyre 3 pore seats 31 can be connected in the annular groove 22 of valve base 2 base lower surfaces and by viscose glue and bond together.
The utility model also can adopt following structure: the base lower surface in valve base is provided with an annular lip, be provided with an annular groove on inner tube of a tyre pore seat, the annular lip of described valve base base lower surface can be connected in the annular groove on the inner tube of a tyre pore seat and by viscose glue and bond together.
Emphasis of the present invention just is: the faying face of setting up an annular lip and groove on the faying face of the base lower surface of valve base and inner tube of a tyre pore seat.
