Description

Technical Field

[0001] The utility model relates to the field of inflating a lifting airbag inflating device, in particular to a lifting airbag inflating device with adjustable air output volume. Background Art

[0002] At present, airbags are used in industry and households for leveling and moving objects. Its structure is that an elastomeric hand-squeezing ball is connected to the airbag through a tube. When the hand squeezes or presses the hand-squeezing ball, the ball deforms, and then the gas in the hand-squeezing ball is pushed into the airbag bag, and the airbag bag will bulge. When the airbag is placed between two objects, the airbag will do work on the two objects due to its bulging, so as to achieve the work of lifting or pushing. The one-way valve in the air release valve of the elastomeric hand-squeezing ball is realized by cutting a small notch in the rubber. Since dust in the air will pad up the notch, the valve cannot be closed tightly, resulting in air leakage from the airbag and slow air leakage. Moreover, the air leakage is more obvious at lower air pressures. Since this type of elastomeric hand-squeezing ball is squeezed inward by hand, it cannot output high pressure, similar to the principle that an egg cannot be crushed when held in the hand. Therefore, a lifting airbag inflating device is proposed, which is pressurized by stepping on it, the air release valve is sealed by a spring pressing against a gasket, and the rubber ball seals the air inlet by gravity, and the inflation volume can be adjusted. Content of the Utility Model

[0003] The purpose of the utility model is to solve the deficiencies existing in the prior art, and to propose a lifting airbag inflating device which is pressurized by stepping on it, the air release valve is sealed by a spring pressing against a gasket, and the rubber ball seals the air inlet by gravity, and the inflation volume can be adjusted. By stepping on the pressure pedal, the weight of a person is converted into pressure, so as to output a very high air pressure. Inside the air release valve, a spring presses against the gasket, and the rubber ball seals the air inlet by gravity, realizing airtightness without air leakage at both low and high pressures.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Referring to Figures 1-3 , an embodiment provided by the present invention is as follows:

[0029] A lifting airbag inflation device with adjustable air output includes a bottom plate 1. The rear end of the upper surface of the bottom plate 1 is fixedly connected with a piston housing 2. Two guide rods 3 are arranged at the upper end of the piston housing 2. Pressing pedals 4 are fixedly connected to the upper surfaces of the guide rods 3. A pressing piston 19 is fixedly connected to the lower surfaces of the guide rods 3. The front end of the upper surface of the bottom plate 1 is fixedly connected with a pressing valve body 8. An air nozzle 7 is fixedly connected to the front end of the outer wall of the pressing valve body 8;

[0030] An air release button 6 is arranged at the upper end inside the pressing valve body 8. The inner bottom surface of the pressing valve body 8 is fixedly connected with a ventilation seat 10. A ventilation groove 15 is opened on the upper surface of the ventilation seat 10. A circulation groove 13 is opened inside the bottom plate 1. Two gas holes 14 are opened at the rear end of the inner top surface of the circulation groove 13. A rubber ball 12 is arranged inside the ventilation groove 15. An installation groove 17 is arranged at the upper end of the ventilation groove 15. A pressing spring 16 is arranged at the upper end of the installation groove 17. Pressing return springs 20 are arranged at the lower ends of the guide rods 3;

[0031] The air output of the lifting airbag inflation device can be adjusted by operating the air release button 6 so as to meet the load-bearing requirements under different needs.

[0032] An air intake groove 11 is opened at the front end of the inner top surface of the circulation groove 13. The circulation groove 13 and the pressing valve body 8 are connected through the air intake groove 11. By opening the air intake groove 11 at the front end of the inner top surface of the circulation groove 13, the circulation groove 13 and the pressing valve body 8 are connected through the air intake groove 11, so that gas can enter the inside of the pressing valve body 8 better. Further, the center of the upper surface of the air release button 6 penetrates through the pressing valve body 8 to the upper end of the pressing valve body 8. An anti-slip pad 18 is fixedly connected to the lower surface of the bottom plate 1. By the center of the upper surface of the air release button 6 penetrating through the pressing valve body 8 to the upper end of the pressing valve body 8, the pressing depth can be effectively controlled. Then, by fixedly connecting the anti-slip pad 18 to the lower surface of the bottom plate 1, the sliding of the bottom plate 1 during work is avoided. A sealing pad 9 is arranged at the edge of the upper surface of the air release button 6. By arranging the sealing pad 9 at the edge of the upper surface of the air release button 6, the sealing performance between the air release button 6 and the pressing valve body 8 can be effectively improved.

[0033] The upper surface of the pressure pedal 4 is provided with anti-slip lines 5. By providing the anti-slip lines 5 on the upper surface of the pressure pedal 4, the anti-slip performance of the pressure pedal 4 can be effectively improved. The upper surface of the pressing spring 16 is fixedly connected to the lower surface of the air release button 6. By fixedly connecting the upper surface of the pressing spring 16 to the lower surface of the air release button 6, the position of the pressing spring 16 can be better fixed. The air nozzle 7 is connected to the pressing valve body 8 in a through manner. By connecting the air nozzle 7 to the pressing valve body 8 in a through manner, the gas can flow better.

[0034] Working principle: When in use, the air tube of the airbag is connected to the air nozzle 7, and then by pressing the pressure pedal 4, the gas is pressed into the flow groove 13, and then the rubber ball 12 is squeezed by the gas. When the driving force of the gas exceeds the self-gravity of the rubber ball 12, the rubber ball 12 rises. When the rubber ball 12 rises, the gaps around it gradually become larger, so that the gas enters the inside of the pressing valve body 8 and then enters the air tube of the airbag through the air nozzle 7, so as to lift or push an object. When the pressure pedal 4 is no longer pressed, the rubber ball 12 seals the ventilation groove 15 by the action of gravity and the elastic force of the pressing spring 16 to prevent the gas from returning. When the work is completed or the height of the airbag needs to be adjusted, by pressing the air release button 6, the air release button 6 descends. When descending, a gap appears between the air release button 6 and the pressing valve body 8. At this time, the high-pressure gas in the airbag enters the pressing valve body 8 through the air nozzle 7 and is discharged through the gap between the air release button 6 and the pressing valve body 8. When the air release button 6 is no longer pressed, the gas in the airbag stops discharging, so that the exhaust volume of the lifting airbag inflation device is changed by the pressing force of the air release button 6.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
