Description

The switch type multiple-way valve of inflatable objects

Technical field

The utility model relates to a kind of multiple-way valve, particularly a kind of switch type multiple-way valve of inflatable objects.

Background technique

Generally be equipped with various valve bodies on the inflatable objects (for example article such as airbed, the little swimming pool of inflation).

If the inflatable objects of an air chamber is only arranged, then only establish a single gas charging valve.

If the inflatable objects of many air chambers, then one of them air chamber is provided with gas charging valve, is provided with through hole to reach the intercommunication between the air chamber on the barrier film between the air chamber.Like this, single air chamber is difficult to reach the pressure of needs.And, oppress an air chamber and will force the gas of this air chamber to flow to adjacent air chamber by the barrier film through hole, cause each air chamber pressure inequality.In addition, if an air chamber gas leakage is arranged, then entire product is scrapped, and Security is low.

The inflatable objects of another many air chamber is not established through hole between each air chamber, and each air chamber is equipped with gas charging valve.This inflatable objects or will inflate respectively to each air chamber, inflation times is many, uses inconvenient; Perhaps will establish the electric power inflator respectively at each air chamber, inflator is many, raises the cost, and does not have a market competitiveness.

Summary of the invention

The purpose of this utility model provides a kind of switch type multiple-way valve that is used for many air chambers inflatable objects, can realize each air chamber intercommunication or not intercommunication of inflatable objects easily.Once inflation can make each air chamber finish inflation simultaneously.

To achieve the above object, the technical solution of the utility model is as follows:

A kind of switch type multiple-way valve of inflatable objects, comprise that at least two one ends are connected to the breather line that each independent air chamber, the other end all are connected to a valve body inner cavity respectively, at least one can move in described valve body inner cavity and the diaphragm seal of salable each breather line and the switch gear that the driving diaphragm seal moves in the valve body inner cavity.

In preferred version of the present utility model, described valve body comprises loam cake and lower shell body, and loam cake and lower shell body driving fit form a cavity, and the lower end surface of lower shell body is provided with at least two vents, and arbitrary vent can extend into a breather line downwards.

Described diaphragm seal comprises the sealing hard packing and is contained in the sealed bolster that seals between hard packing and the breather line.

Described diaphragm seal is provided with a recess, and the position corresponding to recess on the described lower shell body is provided with a fin, and fin snaps in the recess.

Described switch gear comprises knob and Returnning spring; On be covered with a knob hole, the position corresponding to knob hole on the lower end surface of loam cake is provided with a knob base, the lower end surface of knob base is provided with identical but the inclined-plane recess that direction staggers of two position symmetry, shape; Knob is two up big and down small rank cylinders, the external diameter of the last cylinder of knob is greater than the aperture of knob hole, and the external diameter of lower prop is less than the aperture of knob hole, the lower prop of knob inserts in the knob hole and stretches out the upper-end surface that knob base withstands diaphragm seal, a latch is equipped with in the position of the lower prop inclined surface recess of knob, and the two ends of latch are installed in the inclined-plane recess; Between the lower end surface of diaphragm seal and the lower shell body Returnning spring is housed.

An anti-skid formula handle is equipped with in the upper-end surface of the last cylinder of described knob.

Described knob is provided with one and runs through axial air-filled pore, and the lower end surface of the lower prop of knob is provided with several recess that communicates with air-filled pore; The periphery of diaphragm seal is provided with several recess, and the diaphragm seal middle part can cover vent.

Owing to adopt above-mentioned structure, can select each air chamber intercommunication or not intercommunication easily by the switch type multiple-way valve.Open the switch gear of switch type multiple-way valve, under the situation of each air chamber intercommunication, only need once inflate or inflatable objects only need be installed an inflation motor, can be with the sufficient required gas of each air chamber, and the pressure that inflation is finished between each air chamber of back is equal.The switch of off switch formula multiple-way valve, under the situation of each not intercommunication of air chamber, a certain air chamber can not influence other air chamber when gas leakage takes place, and is safe.No barrier film through hole can be when not oppressing a certain air chamber pass pressure and causes each air chamber pressure inequality to other air chamber.
