Description

A kind of tuyere of good airproof performance

Technical field:

The utility model relates to gas-filled pump accessory technical field, refers in particular to a kind of tuyere of good airproof performance.

Background technique:

Air mattress and other inflatable products are accepted by people gradually because of it is light, attractive in appearance, inexpensive, this inflatable product was to inflate and exit with a kind of valve that is fixed on the inflatable product in the past, but the structure of this valve is not quite reasonable, after the inflatable product inflation, the disappointing loss of gas is very fast, often tonifying Qi again, and this just need install the valve of a tonifying Qi in addition on inflatable product, very inconvenient, material is produced in waste simultaneously.

The model utility content:

The purpose of this utility model is at the deficiencies in the prior art, and provides a kind of tuyere of good airproof performance, the simple science of its structural design, good airproof performance, economical with materials.

For achieving the above object, the utility model adopts following technological scheme, it comprises penetrates seat in the bag, internal core print seat, post core, loam cake, internal core print seat is arranged on to be penetrated in the bag in the seat, the activity of post core is plugged in the internal core print seat, and an end of post core is socketed with spring and has locking cap to fix, and is socketed with seal ring on the post core, the lower end surface of internal core print seat is formed with the annular slope that concaves, and the post core forms by seal ring, annular slope can airtight air valve switch.

Describedly penetrate in the bag periphery that seat is wrapped in core print seat and fix.

The described outside of penetrating in the bag seat is bolted with loam cake, loam cake with penetrate in the bag between also be socketed with packing ring, ring body.

Described post core is provided with fixed groove, is socketed with seal ring in the fixed groove.

The utility model beneficial effect is: the activity of post core is plugged in the internal core print seat, one end of post core is socketed with spring and has locking cap to fix, be socketed with seal ring on the post core, the lower end surface of internal core print seat is formed with the annular slope that concaves, the post core forms by seal ring, annular slope can airtight air valve switch, the simple science of its structural design, good airproof performance, simultaneously, economical with materials.

Description of drawings:

Fig. 1 is a decomposition texture schematic representation of the present utility model;

Fig. 2 is a part accessory decomposition texture schematic representation of the present utility model.

Embodiment:

See shown in Fig. 1,2: the utility model comprises penetrates seat 1, internal core print seat 2, post core 3, loam cake 7 in the bag, internal core print seat 2 is arranged on to be penetrated in the bag in the seat 1,3 activities of post core are plugged in the internal core print seat 2, one end of post core 3 is socketed with spring 8 and has locking cap 9 fixing, be socketed with seal ring 4 on the post core 3, the lower end surface of internal core print seat 2 is formed with the annular slope 21 that concaves, and post core 3 forms by seal ring 4, annular slope 21 can airtight air valve switch.

Described seat 1 periphery that is wrapped in core print seat 2 of penetrating in the bag is fixed.

The described outside of penetrating in the bag seat 1 is bolted with loam cake 7, lid 7 with penetrate in the bag 1 between also be socketed with packing ring 6, ring body 5.

Described post core 3 is provided with fixed groove 31, is socketed with seal ring 4 in the fixed groove 31

Be installed on the airbed, during inflation, open loam cake 7, at this moment inflate with the upper end of air pump butt joint gas port, after charging gas, post core 3 forms closed state by seal ring 4, annular slope 21, during exhaust, make spring 8 compression back column spinner cores 3 by lower prop core 3, make the boss 32 on the post core 3 revolve a draw-in groove 22 rotations 90 degree along the inclined-plane, snap in the draw-in groove 22, make gas port be opening state, gas in the airbed is discharged from post core 3 and the gas port that annular slope 21 forms, and shuts loam cake 4 then.

The above only is preferred embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
