Fig. 1 and Fig. 2 are referred to, the utility model provides a kind of technical scheme：A kind of child safety seat support base, including
Base 1, base is placed on automotive seat, then child safety seat is installed on base, and child safety seat is fixed
Into equipment, realize that the support of child safety seat is fixed, fixed strip 2 is arranged with rear side of the base, fixed strip is used for
Equipment and automotive seat are fixed, prevent from producing movement, the lower surface of the base when vehicle runs brake or produces shock
Front end is arranged with rotating casing 3, and the inner surface of the rotating casing is provided with internal thread, and the lower thread of the rotating casing connects
Fix bar 4 is connected to, the upper outside wall of the fix bar is provided with the external screw thread 5 used with screw-internal thread fit, and rotating casing is with consolidating
It is used cooperatively between fixed pole, left rotation and right rotation rotating casing, is driven, changes between external screw thread in internal thread and fix bar on rotating casing
Fix bar is become from the extension elongation in rotation, so as to change the overall height of equipment, to adapt to different vehicle different height
Seat, the bottom of the fix bar is provided with support base 6, and support base contacts with the bottom surface of vehicle, and cooperation is placed on automotive seat
On base so as to supporting whole equipment, vehicle equipment when brake can hit is not moved, the fixation
Bar is provided with pedal 7, and pedal is placed for the foot of children, children is not felt in ride-on vehicles because leg is hanging
To discomfort, the development of child leg bone is also beneficial to, is provided between the lower surface of the pedal and the upper surface of support base
Telescopic system, telescopic system can change the position that pedal is relatively fixed bar, so as to adjust the height of pedal, to adapt to not
With the children of leg length, the telescopic system includes the support bar 801 for being located at support base upper surface, and the top of the support bar is coaxial
Provided with piston rod 802, coordinate between support bar and piston rod, by changing the degree of exposing of piston rod relative support bar, realize
The height regulation of telescopic system, the piston rod inner is provided with nitrogen chamber 803, filled with high pressure nitrogen, the nitrogen in nitrogen chamber
Ventilation passage 804 is communicated between the bottom and top of room, ventilation passage is by by above and below the separated nitrogen chamber of piston rod two
Part connects, and the crown center of the piston rod, which runs through, is provided with adjusting rod 805, and adjusting rod extends into the interior of nitrogen chamber
The lower surface of portion, the upper surface of adjusting rod and pedal is connected, and adjusting rod is used to control at the top of nitrogen chamber to be opened with passage of taking a breath
Close, when adjusting rod is depressed, connected at the top of nitrogen chamber between ventilation passage, can be with circulated gases, when adjusting rod is lifted, nitrogen
Plenum roof and take a breath passage connection be closed, can not circulated gases, be uniformly provided between the adjusting rod and piston rod slow
Rush spring 806, buffer spring makes adjusting rod be lifted in its natural state, to pedal apply pressure when, buffer spring just by
Pressure, adjusting rod is also with pushing, and pressure is smaller or during no pressure, buffer spring keeps nature to make adjusting rod keep lifting
State, piston rod 807 is provided with the bottom center of the support bar, and piston rod extends into the inside of nitrogen chamber, piston
Connecting rod is fixed on the bottom surface of support bar, by nitrogen chamber be divided into up and down two parts, and between do not circulate.
Specifically, the lower surface of the support base is provided with pad 9, and pad enables the fitting automobile that support base is changed
Bottom surface, make support base and fix bar it is stable support equipment, avoid automobile and be moved when braking or being hit.
Specifically, the pedal is provided with groove 10, and groove is easy to what children were more bonded pin is positioned over into pedal
On, children is kept correct sitting posture.
Specifically, the lateral wall bottom of the piston rod is provided with rubber bumper 808, and rubber bumper is enclosed on piston rod
Outside, play a part of buffer deceleration when piston rod declines, avoid because piston rod because being declined suddenly by excessive pressure,
The high pressure nitrogen of inside is caused to explode.
Specifically, the bottom of the piston rod is provided with buffer gasket 809, when piston rod is raised to highest position, delays
Rush packing ring and play a part of limitation protection.
Operation principle：Base is placed on the seat of automobile, fixed strip and automobile are fixed, left rotation and right rotation turning set
Pipe, it is driven in internal thread and fix bar between external screw thread on rotating casing, changes fix bar from the extension elongation in rotation, from
And the overall height of equipment is changed, to adapt to the seat of different vehicle different height, base is bonded the bottom surface of automobile, completes to set
Standby installation, safety seat is installed on support base, and children are seated in safety seat, and foot is put on pedal, to pin
Pedal applies certain pressure, buffer spring compression, and adjusting rod position declines, and connects between the top of nitrogen chamber and ventilation passage
It is logical, it can be continued in nitrogen chamber by the separated gas of two parts up and down of piston rod through passage flow of taking a breath, pedal to piston
Bar force pushes piston rod, declines the position of pedal, if the strength applied is smaller, adjusting rod is pushed, but is not enough to
When pushing piston rod, because two-part gas connection atmospheric pressure value is identical up and down, but the upper surface face of piston rod in nitrogen chamber
To accumulate and be more than lower surface area, the force area of nitrogen is big under same pressure state, and active force is also just big, so piston rod rises,
After the position adjustments of pedal are good, the position of adjusting rod rises, and the connection between the top of nitrogen chamber and ventilation passage is closed
Close, piston rod no longer moves, and buffer spring realizes supporting role to children foot, pair it is achieved thereby that pedal height regulation
To adapt to the children of different leg length.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out with a variety of changes in the case where not departing from principle of the present utility model and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
