Abstract
The utility model discloses a leakproof pump nozzle and belongs to a pump accessory. The conventional pump nozzle can leak the air easily during inflation or pumping. The leakproof pump nozzle comprises a connecting base and a pump needle, and is characterized in that the pump needle is assembled on the connecting base, and an accommodation cavity which is positioned on a flow channel is formed between the pump needle and the connecting base; and a check valve structure is arranged in the accommodation cavity. According to the leakproof pump nozzle, the pump needle is assembled on the connecting base, the accommodation cavity which is positioned on the flow channel is formed between the pump needle and the connecting base, and the check valve structure is arranged in the accommodation cavity, so that the pump nozzle can only ensure that the airflow flows in one direction; and the flow direction of the pump nozzle can be changed by changing the direction of the check valve structure, so that the air leakage during inflation or pumping is prevented, and the pump nozzle is convenient to use.
Description
Technical field
The utility model belongs to the pump accessory, specifically is a kind of leakproof pump mouth.
Background technique
The existing pump mouth inflating, bleed of being used to, its runner all leads directly to, when stop inflation, when bleeding, the object that is inflated, bleeds can use inconvenience from the gas leakage of pump mouth.
The model utility content
The technical problem that the utility model will solve and the technical assignment of proposition are to overcome the existing pump mouth is prone to gas leakage when inflation is perhaps bled defective, and a kind of leakproof pump mouth is provided.
For achieving the above object, the leakproof pump mouth of the utility model comprises connecting base and pump pin, it is characterized in that: said pump pin is assemblied on the connecting base and within the two, forms and is positioned at the receiving cavity on the runner, establishes one-way valve structures in the described receiving cavity.
As the optimization technique means, described one-way valve structures is made up of spool, the sealing valve port that cooperates with spool, and described spool is placed in the receiving cavity, and described sealing valve port is located at an end at the said spool of being positioned at of the said receiving cavity upper reaches.Further, described receiving cavity is built-in with the anti-blocking grid that is positioned at said spool downstream.
As the optimization technique means, described one-way valve structures by the sealing valve port, be located at can digging and can the flap of sealing valve port shutoff be constituted of said sealing valve port downstream one side from the sealing valve port.
As the optimization technique means, described sealing valve port be positioned on the connecting base or the pump pin on.
As the optimization technique means, establish a valve seat in the described receiving cavity, described sealing valve port is positioned on the valve seat.
As the optimization technique means, described pump pin passes through screw fit on connecting base.
As the optimization technique means, described pump pin is bonded on the connecting base.
As the optimization technique means, in the placement hole of described pump pin close-fitting on connecting base.
As the optimization technique means, described one-way valve structures is the one-way ventilating film.
The beneficial effect of the utility model is: be positioned at the receiving cavity on the runner through being assemblied in the pump pin on the connecting base and within the two, forming; In receiving cavity, establish one-way valve structures, make the pump mouth can only air feed flow to a direction and flow, through changing the direction of one-way valve structures; Can change the flow direction of pump mouth; Prevent to leak gas when inflation from perhaps bleeding, raise the efficiency convenient the use.
Description of drawings
Fig. 1 is a kind of pump mouth structure schematic representation that is used to inflate of the utility model;
Fig. 2 is a kind of pump mouth structure schematic representation that is used to bleed of the utility model;
Label declaration among the figure: the 1-connecting base, 2-pump pin, the 3-receiving cavity, the 4-one-way valve structures, the 5-spool, 6-seals valve port, the anti-blocking grid of 7-, 8-placement hole.
Embodiment
Below in conjunction with Figure of description the utility model is further specified.
The leakproof pump mouth of the utility model, like Fig. 1, shown in Figure 2, it comprises connecting base 1 and pump pin 2; Pump pin 2 is assemblied on the connecting base 1 and within the two, forms and is positioned at the receiving cavity 3 on the runner, establishes one-way valve structures 4 in the receiving cavity 3, makes the pump mouth can only air feed flow to a direction flow (flow direction of having expressed air-flow among the figure with arrow); Through changing the direction of one-way valve structures; Can change the flow direction of pump mouth, prevent to leak gas convenient the use when inflation from perhaps bleeding.Connecting base is connected on the air pump during use, and the pump pin inserts the object that needs inflation or bleed.
Concrete; Referring to Fig. 1, Fig. 2; One-way valve structures 4 can be made up of spool 5, the sealing valve port 6 that cooperates with spool; Spool 5 is placed in the receiving cavity 3, and sealing valve port 6 is located at an end that is positioned at the spool upper reaches of receiving cavity: sealing valve port 6 is positioned at connecting base 1 last time (referring to Fig. 1), and the pump mouth is used for inflation; Sealing valve port 6 is positioned at pump pin 2 last times (referring to Fig. 2), and the pump mouth is used to bleed.In addition, also can in receiving cavity, establish a valve seat, the sealing valve port is positioned on the valve seat, can change the purposes of pump mouth through the position of direction and the spool of conversion sealing valve port on valve seat, perhaps bleeds, or inflation.Receiving cavity is built-in with the anti-blocking grid that is positioned at the spool downstream, prevents spool shutoff runner.
In addition, one-way valve structures can be by the sealing valve port, be located at can digging and can the flap of sealing valve port shutoff be constituted of sealing valve port downstream one side from the sealing valve port.At this moment, the sealing valve port also can be positioned on the connecting base or on the pump pin, perhaps in receiving cavity, establishes a valve seat, and the sealing valve port is positioned on the valve seat.One-way valve structures can also be the one-way ventilating film.
Be assemblied in the concrete form on the connecting base as the pump pin, pump pin 2 can be through screw fit on connecting base 2, and perhaps the pump pin is bonded on the connecting base, perhaps in the placement hole of pump pin close-fitting on connecting base.
The pump mouth of the utility model also can be used for filling or extracting liquid, anti-heads.
