The utility model discloses can enlarge or reduce and aerify ball size of accomodating the bag according to the user demand, it is convenient nimble, in addition the utility model discloses, the pump prevents the air pump to be breathed in from the rear portion, and set up the check valve that admits air at big jar front end wall, the end housing sucks outward to make the air pump admit air directly in the past, and is very convenient from the practicality.

Description

A kind of ball storage device with aerification function

Technical field

The utility model relates to sports equipment technical field, is specially a kind of ball storage device with aerification function.

Background technology

Sports have improve the health, amusement, education, politics, the function such as economy, sports also contribute to cultivating the brave indomitable personality of people, the quality gone beyond oneself, the will being ready for the challenge and the ability accepted the risk, and contribute to cultivating the competitive spirit of people, team spirit and fair idea. Currently, people more and more focus on sports and physical culture teaching, participate in sports and accept the people of physical culture training more and more.

Thus the class hour shared by physical education journey in school also gets more and more, and the ball game such as basketball, football and vollyball have become one of favorite teaching of student in the present age. Current physical culture impart knowledge to students more and more focus on practical teaching, it is desired to every student has the chance of training and assessment in person; Therefore, physical culture teaching moves towards playground from classroom on a large scale. Owing to there is certain distance in distance physical culture classroom, playground, and, the basketball, football or the vollyball quantity that need in teaching course reach tens of every time. Cannot being got in the ball playground that is transported to by existing ball laying rack, P.E. teacher ball is placed in a big net by large-scale to basketball, football or vollyball etc. usually, lifts to playground by student's help and provides and use to student; When having a class, then during ball withdrawal is netted. This kind of ball carrying and storage device, it may also be useful to very inconvenient, spheroid easily rolls everywhere, is scattering into each corner on playground, affects the sports of playground order and other people; And, that has also increased the weight of academics and students picks up ball burden, seriously affects the mood of attending class of academics and students.

Practical novel content

The technical problem that the utility model solves is to provide a kind of ball storage device with aerification function, to solve in above-mentioned background technology the problem proposed.

The technical problem that the utility model solves realizes by the following technical solutions: a kind of ball storage device with aerification function, comprise: inflation sidewall, inflation base plate, inflation sidewall forms rectangular parallelepiped collecting bag with inflation base plate, inflation sidewall side is provided with aeration aperture, aeration aperture is connected to aerator pump, aerator pump is bonded and fixed on inflation sidewall, described aerator pump comprises the big cylinder of concentric fit, little cylinder and central row tracheae, its medium and small cylinder, as big cylinder piston rod, is integrally fixed with big cylinder piston; Central row tracheae passes big cylinder front bulkhead as little cylinder piston rod, and be integrally fixed with the little piston of hollow and big cylinder front bulkhead, having air inlet check valve on described big cylinder front bulkhead, big cylinder piston leads to little cylinder place air inlet check valve, and little cylinder piston inner ring surface has exhaust check valve.

Described collecting bag is provided with a slide fastener along its lateral circular, along it longitudinally around being provided with two slide fasteners, slide fastener is coated with the covering sheet that can raise.

It is spaced apart 15-30cm between two chain teeth of described slide fastener.

Compared with prior art, the beneficial effects of the utility model are: the utility model according to user demand, can zoom in or out the size inflating ball collecting bag, convenient, flexible, the utility model in addition, and aerator pump stops air pump from rear portion air-breathing; And set up air inlet check valve at big cylinder front bulkhead, and air pump air inlet is directly sucked from nose shell, very convenient from practicality.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is air pump structure schematic diagram of the present utility model.

Embodiment

In order to make actualizing technology means of the present utility model, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, set forth the utility model further.

As shown in Figure 1 and Figure 2, a kind of ball storage device with aerification function, comprise: inflation sidewall 1, inflation base plate 2, inflation sidewall 1 forms rectangular parallelepiped collecting bag with inflation base plate 2, and inflation sidewall 1 side is provided with aeration aperture 11, and aeration aperture 11 is connected to aerator pump 5, aerator pump 5 is bonded and fixed on inflation sidewall 1, described aerator pump 5 comprises the big cylinder 55 of concentric fit, little cylinder 54 and central row tracheae 56, and its medium and small cylinder 54, as big cylinder piston rod, is integrally fixed with big cylinder piston 57; Central row tracheae 56 passes big cylinder front bulkhead as little cylinder piston rod, and be integrally fixed with the little piston 58 of hollow and big cylinder 55 front bulkhead, having air inlet check valve 51 on described big cylinder front bulkhead, big cylinder piston leads to little cylinder place air inlet check valve 52, and little cylinder piston inner ring surface has exhaust check valve 53.

Described collecting bag is provided with a slide fastener 3 along its lateral circular, along it longitudinally around being provided with two slide fasteners 3, slide fastener 3 is coated with the covering sheet 4 that can raise.

It is spaced apart 15-30cm between two chain teeth of described slide fastener 3.

During use, according to circumstances need to select whether to be pulled open by slide fastener 3 or closed, pull open the volume that can increase collecting bag, under closed state, collecting bag is reduced, subtracts small occupied space.

More than show and describe ultimate principle of the present utility model and main characteristic sum advantage of the present utility model. The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model. Claimed scope of the present utility model is defined by appending claims and equivalent thereof.
