A kind of Manual inflator

Technical field

The utility model relates to inflator technical field, specially a kind of Manual inflator.

Background technique

Traditional pump-up device is piston inflator provided at present, and piston exterior connection catch bar pushes piston to move reciprocatingly reality It now inflates, but the pump-up device of this pushing mechanism is time-consuming and laborious, inefficiency and inconvenient to carry, and in use It is easy to slip out of the hand and causes security risk.

Utility model content

The purpose of this utility model is to provide a kind of Manual inflators, to solve tradition mentioned above in the background art Inflator is time-consuming and laborious, inefficiency and problem inconvenient to carry.

To achieve the above object, the utility model provides the following technical solutions：A kind of Manual inflator, it is characterised in that： It including L shape pedestal, is fixedly connected on L shape pedestal there are two cylinder and support, cylinder is interior to be equipped with piston, is connected with piston on piston Bar, piston rod one end are fixedly connected on guide pad, and sliding block is equipped in guide pad, and crank is connected on sliding block, and crank one end connects It is connected to connecting rod, connecting rod one end passes through support and is connected with handle；Described cylinder one end is equipped with gas nozzle and check valve.

Preferably, the cylinder is fixedly connected by screw bolt and nut with L shape pedestal.

Preferably, the support is fixedly connected by screw bolt and nut with L shape pedestal.

Preferably, the check valve is made of spring, steel ball and intake cover.

Compared with prior art, the utility model has the beneficial effects that：This kind of Manual inflator solves traditional inflator Time-consuming and laborious, inefficiency and problem inconvenient to carry；Two piston rods, which are connected on the same guide pad, makees counter motion, Another cylinder is deflated when one cylinder charge, another cylinder charge when a cylinder is deflated holds pump-up device Continue and inflated into tire, efficiency is inflated in raising, and time saving and energy saving.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Fig. 1-4 is please referred to, the utility model provides a kind of technical solution：A kind of Manual inflator, including L shape pedestal 1, L It is fixedly connected with nut 14 by bolt 13 there are two cylinder 3 and support 2 on shape pedestal 1, cylinder 3 is interior to be equipped with piston 4, piston 4 On be connected with piston rod 5,5 one end of piston rod is fixedly connected on guide pad 6, and sliding block 7 is equipped in guide pad 6, is connected on sliding block 7 There is crank 8,8 one end of crank is connected with connecting rod 9, and 9 one end of connecting rod passes through support 5 and is connected with handle 10；3 one end of cylinder is equipped with gas nozzle 11 and check valve 12, check valve 12 be made of spring 15, steel ball 16 and intake cover 17.

Working principle：When using the Manual inflator, the article that the connection of gas nozzle 11 is needed to inflate, with hand rotational handle 10, connecting rod 9 drives crank 8 to move, and crank 8 drives sliding block 7 to slide in guide pad 6, and guide pad 6 periodically moves left and right, The piston rod 5 being connected on guide pad 6 is reciprocating in cylinder 3 with piston 4；When space becomes larger in a cylinder 3, produce Raw negative pressure, outside air enters in cylinder 3 from check valve 12, at this point, space becomes smaller in another cylinder 3, pressure increases, due to Cylinder 3 is equipped with check valve 12, and high pressure gas can only be output in the article inflated by gas nozzle 11；When in a cylinder 3 When space becomes smaller, pressure increases, and since cylinder 3 is equipped with check valve 12, high pressure gas can only be output to by gas nozzle 11 and be beaten In the article of gas, at this point, generating negative pressure when space becomes larger in another cylinder 3, outside air enters cylinder 3 from check valve 12 Interior, here it is the working principles of the Manual inflator.

Although the utility model is described in detail with reference to the foregoing embodiments, come for those skilled in the art Say, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic into Row equivalent replacement, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should all It is included within the scope of protection of this utility model.
