Abstract
The utility model discloses a children's table chair elevating gear, include from the right side to left foot -operated pump, first one -way pneumatic valve, container and the one -way pneumatic valve of second that connects gradually, the container upper end is equipped with the piston, and the piston upper end is connected with the push rod. The device simple structure, with low costs, the security is good, and the maintenance is easy with the replacement, child oneself just can trample the height of adjustment table chair through the foot, and the existing interest of this kind of mode is favorable to the cultivation of child's independence again.
Description
Technical field
The utility model relates to a kind of lowering or hoisting gear, specifically a kind of Children's desks and chairs lowering or hoisting gear.
Background technology
The tables and chairs used in public places are generally fixing.But because the build of child is different, use same tables and chairs, be inappropriate for a lot of child.The height of tables and chairs can not adjust, very inconvenient when making a lot of child learn and have dinner.Although some tables and chairs has liftable mechanism, the bayonet socket of these mechanisms is all leak outside, sometimes encounters because of carelessness, scratch will occur; Some children are more naughty, can stir the switch of elevating mechanism, cause the accident.
Utility model content
The purpose of this utility model is to provide a kind of Children's desks and chairs lowering or hoisting gear, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of Children's desks and chairs lowering or hoisting gear, comprises the pedal inflating pump, the first unidirectional air pressure valve, container and the second unidirectional air pressure valve that connect successively from right to left; Described container upper end is provided with piston, and piston upper end is connected with push rod.
As further program of the utility model: piston adopts rubber to make, and push rod adopts anti abrasive stainless steel material to make.
Compared with prior art, the beneficial effects of the utility model are: this apparatus structure is simple, and cost is low, and security is good, and maintenance and replacement are easily; Child oneself just can trample the height of adjustment tables and chairs by pin, this mode is not only interesting but also be conducive to the cultivation of child's independence.
Accompanying drawing explanation
Fig. 1 is the structural representation of Children's desks and chairs lowering or hoisting gear.
Fig. 2 is the structural representation that Children's desks and chairs lowering or hoisting gear rises.
Fig. 3 is the structural representation that Children's desks and chairs lowering or hoisting gear declines.
Wherein: 1-pedal inflating pump, the unidirectional air pressure valve of 2-first, 3-tracheae, 4-container, 5-piston, 6-push rod, the unidirectional air pressure valve of 7-second.
Detailed description of the invention
Be described in more detail below in conjunction with the technical scheme of detailed description of the invention to this patent.
Refer to Fig. 1-3, a kind of Children's desks and chairs lowering or hoisting gear, comprise the unidirectional air pressure valve 2 of pedal inflating pump 1, first, container 4 and the second unidirectional air pressure valve 7 that connect successively from right to left; Described container 4 upper end is provided with piston 5, and piston 5 upper end is connected with push rod 6.Piston 5 adopts rubber to make, and push rod 6 adopts anti abrasive stainless steel material to make.
Operation principle of the present utility model is: when this device rises, and the power that applies is in pedal inflating pump 1, and in tracheae 3, produce gas, gas backs down the little steel ball in the first unidirectional air pressure valve 2, and gas can continue to pass through, and gas enters in container 4; Gas in container 4 gets more and more, and can produce the effect of power to piston 5, piston 5 drives push rod 6 to move up, thus realizes rising function; When this device declines, the power that applies, in the second unidirectional air pressure valve 7, backs down the little steel ball inside the second unidirectional air pressure valve 7, flows out inside gas from vessel 4, and the air pressure that container is 4 li reduces, and piston 5 drives push rod 6 to move down, thus realizes decline function.This apparatus structure is simple, and cost is low, and security is good, and maintenance and replacement are easily; Child oneself just can trample the height of adjustment tables and chairs by pin, this mode is not only interesting but also be conducive to the cultivation of child's independence.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, can also makes a variety of changes under the prerequisite not departing from this patent aim.
