Abstract

The utility model relates to an extension device of an inflating valve for a tire, which is used for extension aeration of the inflating valve for the tire of vehicle and comprises a lengthening valve core component (1), an extension tube of the inflating valve (2) and a sealing component (3), wherein, the lengthening valve core component (1) comprises a valve core (1.1) and an extension rod of the valve core (1.2), wherein, the extension rod of the valve core (1.2) is connected with the tail of the valve core (1.1); the extension tube of the inflating valve (2) is a hollow tube, one end of the extension tube of the inflating valve (2) is provided with an internal thread while the other end is provided with the internal thread and an external thread; the lengthening valve core (1) is arranged in the extension tube of the inflating valve (2) and the valve core (1.1) of the lengthening valve core component (1) is arranged at the ends of the internal thread and the external thread in the extension tube of the inflating valve (2); the tail end of the extension rod of the valve core (1.2) is close to the end of the internal thread in the extension tube of the inflating valve (2); the sealing component (3) is embedded between the tail end of the extension rod of the valve core (1.2) and the inner wall of the extension tube of the inflating valve (2). The extension device can aerate the tires at long bowls when the tires are difficult to be directly aerated.

Description

Tyre inflation valve extending apparatus

Technical field

The utility model relates to a kind of valve cock, especially relates to a kind of tyre inflation valve extending apparatus.The tyre valve that is mainly used in various vehicles extends inflation.Belong to the auto parts machinery technical field.

Background technique

Conventional valve cock is installed in the valve hole of tyre rim, is used for inflating in tire, and valve inside is housed in the valve cock.During inflation, the Inflation clamping head of inflator clamped or by on the mouth mouth that is screwed at valve cock, the valve inside in the unseat the valve mouth is inflated simultaneously; Inflation finishes, and unclamps the Inflation clamping head of inflator, the sealing that automatically resets of the valve inside in the valve cock.Because the mouth pipe of conventional valve cock is shorter, when therefore using conventional inflator that tyre valve is inflated, but operating distance is far away, the Inflation clamping head of inflator put in stretch out not too convenient, the mouth mouth of Inflation clamping head and valve cock is difficult to clamping, if directly the tyre valve of routine is inflated, particularly tyre valves such as truck, motor bus, truck are inflated just not too suitable.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of mouth pipe that can prolong tyre valve is provided, so that the tyre inflation valve extending apparatus that various vehicle tyres are inflated at a distance.

The purpose of this utility model is achieved in that a kind of tyre inflation valve extending apparatus, it is characterized in that described device comprises to add long core assembly, valve cock extension tube and Sealing,

The described long core assembly that adds comprises valve inside and valve inside extension rod, and the afterbody of valve inside extension rod and valve inside connects and composes and adds the long core assembly;

Described valve cock extension tube is a hollow tubular structure, one end of valve cock extension tube is shaped on internal thread, be used for the tyre rim hole in valve cock be spirally connected, the other end of valve cock extension tube is shaped on internal and external screw thread, internal thread is convenient to and the external thread bolt connection that adds on the valve inside of long core assembly, and outside thread then is convenient to and being threaded of Inflation clamping head and protective hat.

The described long core assembly that adds is installed in the valve cock extension tube, and make the valve inside that adds the long core assembly place the interior internal and external screw thread end of valve cock extension tube, the tail end of valve inside extension rod places in the valve cock extension tube near female end, set Sealing between the tail end of described valve inside extension rod and the valve cock extension tube inwall, be convenient to the tyre rim hole in valve cock mouth mouth sealing.

Because the utility model tyre inflation valve extending apparatus with the valve cock mouth pipe extend outwards of giant tire, can be realized the tire that inconvenience is directly inflated is inflated at a distance.Therefore go for the remote inflation of various vehicle tyres.

Fig. 2 is the assembly figure that adds the long core assembly of the utility model tyre inflation valve extending apparatus.

Fig. 3 is the valve cock extension tube structural representation of the utility model tyre inflation valve extending apparatus.

Fig. 4 is the plan view of Fig. 3.

Fig. 5 is the application implementation schematic representation of the utility model tyre inflation valve extending apparatus.

Among the figure: add long core assembly 1, valve cock extension tube 2, Sealing 3, valve cock 4.

Embodiment

Referring to Fig. 1, the utility model is a kind of tyre inflation valve extending apparatus, mainly forms by adding long core assembly 1, valve cock extension tube 2 and Sealing 3.

Referring to Fig. 2, the described long core assembly 1 that adds is made up of valve inside 1.1 and valve inside extension rod 1.2.The afterbody riveted joint of valve inside extension rod 1.2 and valve inside 1.1 or direct socket or employing patch to connect and compose and add long core assembly 1;

Referring to Fig. 3 and 4, described valve cock extension tube 2 is a hollow tube, the peripheral hardware hexgonal structure, and an end of valve cock extension tube 2 is shaped on the internal thread with valve cock mouth interface external thread coupling, be called for short the inner, the other end of valve cock extension tube 2 is shaped on the internal and external screw thread that meets the valve cock standard.

Referring to Fig. 1, adding long core assembly 1 is installed in the valve cock extension tube 2, and make the valve inside 1.1 that adds long core assembly 1 place internal and external screw thread end in the valve cock extension tube 2, the tail end of valve inside extension rod 1.2 places close female end in the valve cock extension tube 2, sets Sealing 3 between the tail end of described valve inside extension rod 1.2 and valve cock extension tube 2 inwalls.

Working principle:

During inflation, the inner with the utility model tyre inflation valve extending apparatus is that female end is stretched to tire by the distant place earlier, and the inner of valve cock extension tube 2 and the valve cock 4 in the tyre rim hole are spirally connected, and sees Fig. 5.So just the mouth pipe of valve cock in the tyre rim hole is extended to the outer end of valve cock extension tube 2; The outer end that again Inflation clamping head of special-purpose inflator is directly clamped the valve cock extension tube 2 of tyre inflation valve extending apparatus is the internal and external screw thread end, valve inside in the while unseat the valve mouth extension tube 2, and the tail end of the valve inside extension rod 1.2 in the valve cock extension tube 2 backs down the valve inside in the valve cock in the tyre rim hole simultaneously, inflates; Inflation finishes, and unclamps the Inflation clamping head of inflator, the sealing that automatically resets of the valve insides in valve inside in the tyre rim hole in the valve cock and the valve cock extension tube 2.
