Occupy the situation of base space so that product can adapt to the design needs of more multi-state.
Further, the support for rotary disc includes two support elements being arranged side by side, and the top surface of each support element is respectively equipped with
Two claws.
Two support elements respectively set the design of two claws to provide better adaptability.For three claws,
Four claws can realize that claw is not directed to the limitation of turntable still to realize the limiting to turntable in the case of the turntable center of circle, because
This can carry out the shape of flexible adjustment claw, position and size according to the needs of child restrainnt system inner components, more
Add flexibly.The Redundancy Design of four claws can also effectively improve the stability of child restrainnt system, and turntable constraint failure is avoided to bring
Security risk.
Further, the support element is the plate of vertically-arranged, and support element base carries flanging, which fits with pedestal
And it is bolted；The claw is located at the apical margin of place support element.
The support element of plate is readily produced, the yield that can effectively reduce that increased production cost, while the claw for passing through top surface
It can easily be provided for turntable compared to horizontally tilted different gradients, greatly reduce design, the difficulty of production is user
The use feeling of more diversification is provided.
Further, two claws on same support element are oppositely arranged, the apical margin of each claw and place support element it
Between form card slot, the edge of the turntable is stretched into and is limited in each card slot.
The difficulty of assembling while installation strength is ensured, can be reduced by the edge mate of card slot and turntable, to zero
The error requirements of component are low, can reduce production cost.And simple structure can be used on different types of product, carried
High adaptability.
Further, the apical margin of the support element is equipped with the folding ear of support turntable bottom surface.
The contact area of support element and turntable can be effectively reduced so as to reduce frictional force by rolling over ear support turntable.Pass through
The abrasion of turntable and support element can easily be protected by changing the parameters such as the thickness of folding ear, hardness, so as to extend life of product, be carried
Rise stability.
Further, it is equipped between two support elements and strengthens connector.
The intensity of support element can be effectively improved by strengthening connector, so as to improve the stability of turntable, avoid children about
Beam system constrains the situation of failure in traffic accident.
Further, the periphery strengthened connector and be in turntable, has and turntable profile in the region of neighbouring turntable
Adaptable curved edge.
The reinforcement connector of curved edge can be strengthened not influencing in the case of parts as far as possible to increase in pedestal
The area of connector, so as to provide more stable stiffening effect.
Further, the pedestal is equipped with the rotary locking mechanism with turntable phase separation.
Rotary locking mechanism can avoid child restrainnt system arbitrarily rotated in traffic accident and caused by secondary injury.
When rotary locking mechanism is completed to lock, the child restrainnt system of the disclosure is capable of providing similar with mill run be stably connected with
Effect, when user needs rotation, the child restrainnt system of the disclosure can easily realize rotation, promote user's use feeling
By.
Further, the rotary locking mechanism includes：
The drawing handle being slidably mounted on pedestal；
Lock pin on the drawing handle；
The elastic drive part for acting between drawing handle and pedestal, drawing handle being driven to enter locking bit；
The opposite sides of the drawing handle is equipped with the pilot hole of bar shaped, and the pedestal is equipped with and is respectively protruding into each pilot hole
Interior lead.
The relative position relation of pedestal and turntable is locked by lock pin, is locked so as to fulfill rotation, effect easy to operate is good.
Further, the lock pin is two, and the same side of two lock pins is connected with each other the structure that takes the shape of the letter U, the bottom of U-shaped
It is fixedly mounted in drawing handle.
The lock pin of U-shaped is capable of providing the locking intensity of bigger compared to single lock pin, so as to avoid the situation of accidental unlocking.
Further, the pedestal is equipped with limiting briquetting, limits and is back and forth transported equipped with guiding lock pin between briquetting and pedestal
Dynamic limit channels.
Limiting briquetting can limit the motion path of lock pin, and help claw spacing rotating disk together, be installed above turntable
There is the seat that volume is larger and need to take children, can be generated at turntable by leverage when movement tendency occurs for seat
Larger stress, the limit function that the lock pin limited by limiting briquetting can help claw to undertake turntable, elongated component service life.
Further, pitch regulation frame is fixed on the turntable, the chair angle is adjustable to be mounted on pitch regulation
On frame.
The cooperation rotation of pitch regulation frame can greatly improve the degree of freedom of user, and user is facilitated to use this in different scenes
Disclosed child restrainnt system.
Further, it is equipped with to coordinate with the lock pin on the turntable and/or pitch regulation frame and be rotated with locating turntable
The locked groove of angle.
It can set locked groove that can increase the intensity of locking on pitch regulation frame, avoid accidental unlocking, improve safety
Energy.
Further, the locked groove is distributed as at least two groups in the circumferential, and every group there are two corresponding wherein one locks respectively
Pin.
" in circumferential direction " is referred in the circumferential direction of " turntable and/or pitch regulation frame ", can equipped with multigroup be advantageous in that
Seat is locked in different location, can improve the adaptability of child restrainnt system, improves user's operation experience.
The utility model has the following advantages：
