Description
Technical field
The utility model relates to a kind of manual charger, particularly relates to a kind of switch valve structure of bidirectional inflating hand-pulled inflator.
Background technique
Current hand-pulled inflator (being also gas-filled pump) kind is quite a lot of, there is the hand-pulled inflator of unidirectional inflation, with the hand-pulled inflator of bidirectional inflating, no matter which kind of hand-pulled inflator, all comprise the body with a tubular, be assembled with a piston operated by connecting rod in the body, all sides of piston are provided with Sealing, and the handle be provided with in connecting rod top for user's handling, extend a gas tube in body lower end or upper end.The hand-pulled inflator of unidirectional inflation, moves up and down in a round trip at piston, and be merely able to have single stroke to provide aeration, utilization efficiency is lower.The hand-pulled inflator of bidirectional inflating can push away at handle, draw in two-way travel and all carry out inflation action, and improves utilization efficiency.
Unidirectional inflation or bidirectional inflating can be selected for making the hand-pulled inflator of bidirectional inflating, it generally covers upper the exhaust port having and be communicated with upper gas chamber and the external world, exhaust port place arranges pluggable plug, during bidirectional inflating, blocked by plug, upper gas chamber and extraneous blocking-up, during unidirectional inflation, extract plug, upper gas chamber is communicated with the external world.For preventing plug from losing, connected between plug and stack shell by rope, this makes inflator profile unsightly, and plug plug repeatedly can cause plug poorly sealed and leak gas.For preventing leaking gas between plug and exhaust port, combine relatively tightr between plug and exhaust port, therefore plug plug compare effort.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of switch valve structure without the need to switching valve being extracted the bidirectional inflating hand-pulled inflator that just can carry out handover operation for above-mentioned prior art present situation, and it has the advantage that convenient, the laborsaving and switching valve of handover operation is not easily lost.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of switch valve structure of bidirectional inflating hand-pulled inflator, comprise stack shell and be located at the upper cover on stack shell top, in stack shell, be provided with the piston inner space of stack shell being separated into upper gas chamber and lower chamber; It is characterized in that: on described, cover the exhaust port having and be communicated with upper gas chamber and the external world, rotate in exhaust port and be provided with manual switchover valve to have in manual switchover valve to be communicated with upper gas chamber and extraneous switching channel; Under manual switchover valve turns to an angle state, switching channel is communicated with upper gas chamber and the external world; Under manual switchover valve turns to another angle state, switching channel blocks upper gas chamber and is communicated with extraneous.
For preventing gas leakage, between above-mentioned manual switchover valve periphery and exhaust port inwall, be provided with seal ring.
The inner sidewall of above-mentioned exhaust port has ventilation mouth, and the switching channel of described manual switchover valve is a blind hole, the inner perisporium of switching channel has the inner communicated with switching channel and exports; Turn to inner outlet with under ventilation mouth relative status at manual switchover valve, switching channel is communicated with upper gas chamber and the external world; Turn to inner outlet with under the complete misaligned state of ventilation mouth at manual switchover valve, switching channel blocks upper gas chamber and is communicated with extraneous.Determine that inner outlet is relative with ventilation mouth or misplace by rotation manual switching valve, whether realize the conducting in upper gas chamber and the external world, mode of operation simple possible.
There is outside above-mentioned manual switchover valve the spanner portion exposing outside upper cover, the outside of upper cover have side convex keep off the stopper of joining with spanner portion; Under the side contact condition that spanner portion turns to stopper, switching channel is communicated with upper gas chamber and the external world; Rotate backward to under the opposite side contact condition of stopper in spanner portion, switching channel blocks being communicated with of upper gas chamber and the external world.The setting in spanner portion, be convenient to manipulation switching valve and rotate switching, the rotation angle Constrained effect arranged switching valve of stopper, is joined by the gear of stopper to spanner portion simultaneously, points out us to be switched to specific works mode bit, operate more humane.
Above-mentioned manual switchover valve has the cylindrical portion exposing upper cover, described spanner portion is located in this cylindrical portion, cylindrical portion periphery has one section of curve bath, the upper-end surface of described stopper has raise up and between left and right every setting in limited part, this limited part inserts in curve bath; Under the side inwall of curve bath and the limited part conflict state of side, switching channel is communicated with upper gas chamber and the external world; Under the opposite side inwall of curve bath and the limited part conflict state of opposite side, switching channel blocks upper gas chamber and is communicated with extraneous.By coordinating of limited part and curve bath, realize the rotary spacing to manual switching valve.
Compared with prior art, the utility model has the advantage of: this switch valve structure only need rotate switching valve, just the switching of unidirectional inflation and bidirectional inflating can be realized, without the need to switching valve is extracted, easy to operate, switching valve is not easily lost, structure is more succinct, and in addition, the sealing effect of switching valve and exhaust port also can not reduce because repeatedly switching.

Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
As shown in figures 1-4, be a preferred embodiment of the present utility model.
A switch valve structure for bidirectional inflating hand-pulled inflator, comprising stack shell 1 and is located at the upper cover 2 on stack shell 1 top and the base 3 of bottom, for removably connecting between upper cover 2 and stack shell 1, can be threaded, and also can connect by buckle.The piston 4 inner space of stack shell 1 being separated into upper gas chamber 11 and lower chamber 12 is provided with in stack shell 1; Upper cover 2 central authorities are equipped with linkage tube 7, and the upper end of linkage tube 7 is connected with handle 8, and the lower end of linkage tube 7 is connected with piston 4, as the hand-pulled inflator of bidirectional inflating, are also provided with interior pipe 9 in linkage tube 7.
Upper cover 2 has and is communicated with upper gas chamber 11 and extraneous exhaust port 21, the inner sidewall of exhaust port 21 has ventilation mouth 211, rotates and is provided with manual switchover valve 5, be provided with seal ring 6 between manual switchover valve 5 periphery and exhaust port 21 inwall in exhaust port 21.Have in manual switchover valve 5 to be communicated with upper gas chamber 11 and extraneous switching channel 51, switching channel 51 is a blind hole, the inner perisporium of switching channel 51 has the inner communicated with switching channel 51 and exports 511.
