Description

The little valve of eccentric

Technical field

The utility model relates to a kind of valve of inflator, particularly a kind of valve that can use in small space.

Background technique

The little tire of gas-filled type often is arranged on valve concealed inner chamber at present, plenum space is very narrow and small, its plenum space only is 35mm * 35mm, for the ease of little tyre inflation, its valve generally adopts inipple, be connected on the valve of little tire with the screwed union of manual mode, inflate then spiral valve; After inflation finishes, with manual mode the screwed union of spiral valve is unscrewed again and withdraw from; Its deficiency: the one, install and remove loaded down with trivial details, waste time and energy, in small space mounting or dismounting screwed union particularly the difficulty; The 2nd, screwed union also exists a drawback when giving little tyre inflation, after inflation finishes, in dismounting screwed union process, gas in the tire can spill from meet the crack, concerning giant tyre, may influence not quite, concerning little tire, if dismantle slow words, gas in the little tire even meeting light leak do not reach the purpose of inflation; The 3rd, the moving rotation of the clamping armrest of screwed union, the clamping force size is difficult to control, influences the valve reliability during operation.Also be not suitable for the only little valve of the fast folder quick-release about 35mm * 35mm of plenum space in the market.For this reason, many manufacturers and knowledgeable people have carried out improvement and research repeatedly, design many different schemes, but do not have ideal method to solve the problems referred to above so far as yet.

Summary of the invention

For overcoming the above-mentioned disadvantage that existing valve exists, problem to be solved in the utility model provides a kind of simple and reasonable, little valve of use eccentric easy to operate, good reliability.

The technological scheme that its technical problem that solves the utility model adopts, it comprises mouth body, spanner, rubber sleeve, pressure core, spanner is hinged by bearing pin and mouth body, the band of gas is fixedly mounted on the air input joint, described air input joint is connected on the notch of mouth body and with pressing core fixedlys connected, rubber sleeve and pressure core are successively set in the chamber of mouth body, and air input joint communicates with the inner chamber of pressing core.

Stagger α angle and of the described air input joint mouth body center a that offsets to one side, spanner and air input joint, the span of a and b to opposite side skew mouth body center b between 1mm to 3mm, the span at α angle at 10 degree between 30 degree.

For the ease of operating in narrow space, the switching angle of described spanner is between 45 degree are spent to 75.

After adopting said structure, the utility model can be realized inflation to the steamboat tire in the small space about 35mm * 35mm, the clamping of valve is finished in a short period of time with unclamping by wrench, has therefore solved the inflation back and can produce the defective of gas leakage in release process; Because the displacement amount that spanner clamps is constant, the elastic compression power basically identical that rubber sleeve produces, so valve remains unchanged substantially to the clamping force of valve, this has just guaranteed the reliability of valve work; At different air valves such as Mei Zui, English mouth or method mouths, select corresponding pressure cored structure for use, can the little tire of different air valve be inflated; Have simple and compact for structure, characteristics such as use is easy to operate, good reliability.

Embodiment

Shown in Figure 1, specific embodiments for the little valve of a kind of eccentric of the utility model, it comprises mouth body 1, spanner 5, rubber sleeve 2, presses core 3, spanner 5 is hinged by bearing pin 4 and mouth body 1, the band of gas 6 is fixed on the air input joint, described air input joint is connected on the notch of mouth body 1 and with pressing core 3 fixedlys connected, rubber sleeve 2 and press core 3 to be successively set in the chamber of mouth body 1, and air input joint communicates with the inner chamber of pressure core 3.The described air input joint mouth body 1 center a that offsets to one side, stagger α angle and of spanner 5 and air input joint to opposite side skew mouth body 1 center b, the span of a and b is between 1mm to 3mm, and best value is 2mm, to between 30 degree, best angle is 15 degree to the span at α angle at 10 degree.To between 75 degree, best switching angle is 60 degree to the switching angle of described spanner 5 at 45 degree.Like this, the utility model can be realized inflation to the steamboat tire in the small space about 35mm * 35mm; The clamping of valve with unclamp by wrench 5 control, therefore can finish in a short period of time, the inflation back can not produce gas leakage in release process; Because the displacement amount that spanner 5 clamps is constant, the elastic compression power basically identical that rubber sleeve 2 produces, so valve remains unchanged substantially to the clamping force of valve, this has just guaranteed the reliability of valve work.

When the utility model cooperates inflation with U.S. mouth valve, as shown in Figures 2 and 3, press core 3 to select for use the U.S. mouth that is complementary with U.S. mouth valve to press core 3, U.S. mouth presses the center of core 3 that center-pole is arranged, its operating process is as follows: hold on the band of gas 6 and spanner 5 mouth body 1 is stretched into steamboat tyre valve place, the central aperture valve of rubber sleeve 2 also inserts proper depth, downward switching spanner 5, spanner 5 is pressed core 3 extruding rubber sleeves 2 by U.S. mouth, rubber sleeve 2 produces resiliently deformable and clamps valve, U.S. mouth is pressed the center-pole while roof pressure valve inside of core 3, makes valve be communicated with inflation with the steamboat tire.After inflation was finished, switching spanner 5 resetted, and extracted to be inserted in laterostigmatal mouth body 1 and to get final product.

When the utility model cooperates inflation with English mouth or method mouth valve, as shown in Figure 4 and Figure 5, pressure core 3 selects for use the English mouth that is complementary with English mouth or method mouth valve to press core 3, its operating process is as follows: hold on the band of gas 6 and spanner 5 mouth body 1 is stretched into steamboat tyre valve place, the central aperture valve of rubber sleeve 2 also inserts proper depth, downward switching spanner 5, and spanner 5 is pressed core 3 extruding rubber sleeves 2 by U.S. mouth, rubber sleeve 2 produces resiliently deformable and clamps valve, makes valve be communicated with inflation with the steamboat tire.After inflation was finished, switching spanner 5 resetted, and extracted to be inserted in laterostigmatal mouth body 1 and to get final product.
