Description

Single hole is used valve more

Technical field

The utility model relates to a kind of valve of inflator, the general valve that particularly a kind of Mei Zui, English mouth or method mouth can both use.

Background technique

At present, Mei Zui, English mouth or method mouth can general its attachment hole of valve be diplopore, realize respectively Mei Zui, English mouth or method mouth are inflated by the attachment hole of different structure; The single hole valve that can have certain versatility simultaneously is disassembling and replacing type Mei Zui and the dual-purpose valve of English mouth, and its feature is that rubber sleeve is applicable to U.S. mouth with pressure core one end that matches, and the other end is applicable to the English mouth, and seals with blind nut; During use, if need to give the valve inflation of another kind of mode, the blind nut of need outwarding winding with rubber sleeve, press the core commutation, screws the conversion that can realize the mode of inflating behind the blind nut; Its shortcoming be change loaded down with trivial details, waste time and energy, tightness requires high, versatility weak effect, and rubber sleeve when changeing, presses greasy dirt on core operator's the hand of can making dirty, it is very inconvenient to change, and concerning the operator who is ignorant of structural principle, also can't change.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 provide a kind of simple and reasonable, use single hole easy to operate, good reliability to use valve more.

The technological scheme that its technical problem that solves the utility model adopts, it comprises the mouth body, rubber sleeve, valve body, press core, decenter clutch, decenter clutch and mouth body are hinged, described rubber sleeve, valve body, press core to be successively set in the mouth body of hollow, decenter clutch is complementary with pressing core, be provided with movable spool in the chamber of valve body, movable spool is provided with spring, spring is arranged on the projection of movable spool and presses between the core, the head of movable spool stretches in the center hole of rubber sleeve, press core to be provided with and the corresponding shrinkage pool of movable spool afterbody, the intake duct on the mouth body communicates with the inner chamber of valve body.

In order to realize respectively on same valve that to Mei Zui and the inflation of English mouth valve described decenter clutch is provided with the different eccentric step of elementary and whole level of two-stage deflection radius, elementary eccentric step is U.S. mouth inflation usefulness, and the eccentric step of level is used for the inflation of English mouth eventually.

From the mouth body and press slit leakage between the core, described pressure core is provided with the seal ring with hollow mouth body inner wall sealing in order to prevent to inflate.

For the ease of inflation, described movable spool is provided with an end and communicates with the inner chamber of valve body, the air flue that the other end communicates with the center hole of rubber sleeve.

After adopting said structure, by the switching decenter clutch on different steps, make and press core to promote valve body, valve body compressing rubber sleeve produces resiliently deformable and clamps valve, and try hard to recommend moving U.S. nozzle valve core by spring and open valve, be implemented on the same valve and can inflate Mei Zui, English mouth or method mouth valve respectively; Have simple and reasonable, characteristics such as use is easy to operate, good reliability.

Embodiment

Shown in Figure 1, use the specific embodiments of valve for a kind of single hole of the utility model more, it comprises mouth body 1, rubber sleeve 2, valve body 3, press core 6, decenter clutch 8, decenter clutch 8 is hinged by bearing pin 9 and mouth body 1, described rubber sleeve 2, valve body 3, press core 6 to be successively set in the mouth body 1 of hollow, decenter clutch 8 is complementary with pressing core 6, be provided with movable spool 4 in the chamber of valve body 3, movable spool 4 is provided with spring 5, spring 5 is arranged on the projection of movable spool 4 and presses between the core 6, the head of movable spool 4 stretches in the center hole of rubber sleeve 2, presses core 6 to be provided with and the corresponding shrinkage pool of movable spool 5 afterbodys, and the intake duct on the mouth body 1 communicates with the inner chamber of valve body 3.Described decenter clutch 8 is provided with two-stage deflection radius different elementary and whole level eccentric step A, B, guarantees to realize respectively on same valve to Mei Zui and the inflation of English mouth valve.Described pressure core 6 is provided with the seal ring 7 with hollow mouth body 1 inner wall sealing, leaks from the slit between mouth body 1 and the pressure core 6 when preventing to inflate.For the ease of inflation, described movable spool 4 is provided with an end and communicates with the inner chamber of valve body 3, the air flue that the other end communicates with the center hole of rubber sleeve 2.

When the utility model cooperates inflation with U.S. mouth valve, as shown in Figures 2 and 3, U.S. mouth valve is inserted in the rubber sleeve 2, switching decenter clutch 8 engages to elementary eccentric step A and with pressing core 6, decenter clutch 8 promotes valve body 4 compressing rubbers cover 2 by pressing core 6, make rubber sleeve 2 produce resiliently deformable and clamp U.S. mouth valve, reach the requirement of sealing, meanwhile, press core 6 pressure springs 5 and movable spool 4, the elastic force of spring 5 requires the active force greater than the valve inside internal valve of opening U.S. mouth, and promotion activity spool 4 is opened the valve inside internal valve of U.S. mouth under the effect of spring 5 elastic force, makes the inflation body be communicated with inflation with the valve inner chamber, after inflation is finished, switching decenter clutch 8 resets, and rubber sleeve 2 resets and unclamps U.S. mouth valve, extracts mouth body 1 and gets final product.

When the utility model cooperates inflation with valves such as English mouth or method mouths, as shown in Figure 4 and Figure 5, English mouth or method mouth valve are inserted in the rubber sleeve 2, switching decenter clutch 8 engages to the whole eccentric step B of level and with pressing core 6, decenter clutch 8 promotes valve body 4 compressing rubbers cover 2 by pressing core 6, makes rubber sleeve 2 produce resiliently deformable and clamps English mouth or method mouth valve, because rubber sleeve is thicker, amount of deformation is big, therefore can reach the requirement of sealing English mouth or method mouth; Meanwhile, movable spool 4 moves after certain displacement owing to be subjected to the relative valve transfixion that stops of English mouth or method mouth valve, presses core 6 pressure springs 5, and the tail end of movable spool 4 stretches in the shrinkage pool of pressing core 6, avoid the interference with valve, thereby make the inflation body be communicated with inflation with the valve inner chamber; After inflation was finished, switching decenter clutch 8 was to start bit, and rubber sleeve 2 resets and unclamps English mouth or method mouth valve, and spring 5 automatically resets, and extracts mouth body 1 and gets final product.
