Description

A kind of children trolley separate type seat retrieving structure

Technical field

The utility model is related to infant articles technical fields, and in particular to a kind of baby child's hand push facilitating folding and expansion Bassinet structure.

Background technology

With the improvement of living standards, tool of the perambulator at babies' indispensability, infant is put onboard by being grown up The nurse action of big people can not only be significantly facilitated by push walking, moreover it is possible to keep baby itself more comfortable, while also more Safety.However, baby stroller at present on the market is typically more complicated, it is largely not foldable, stores up and carry all It is inconvenient.To solve the above-mentioned problems, someone devises foldable baby carriage, however, previous perambulator needs manually mostly Individually pull（Or it pushes）Each component such as handle pipe, front foot pipe, rear foot tube, mounting pipe folds to realize, and this manual operation Mode is more time-consuming, and operation is cumbersome, and is difficult to singlehanded completion operation, can be made to the weaker user of some manipulative abilities At inconvenience, especially it is detrimental to old man and women uses.In addition, traditional perambulator is all seat is made of one structure with vehicle frame, Cannot be arranged in pairs or groups use respectively, once seat or vehicle frame are impaired, it is possible to lead to whole scrap.

Utility model content

The technical problem to be solved by the present invention is to provide a kind of structure more reasonable design, expansion operation and folding operations More convenient, labour-saving children trolley separate type seat retrieving structure, and the separate type seat can individually be removed from vehicle frame with Other vehicle frames are used cooperatively.

In order to solve the above technical problems, the utility model adopts the following technical solution：A kind of children trolley separate type seat Retrieving structure includes seat tubes, seat upper tube and seat down tube, it is characterised in that：The lower end of seat upper tube is connected with pass The upper end of section, seat down tube is connected with hypozygal, and seat upper tube is connected with each other shape with seat down tube by upper joint and hypozygal At rotatable folding structure；The front end of seat tubes connect to form rotary structure by shaft with seat down tube, in seat tubes Portion position is connect by pivot pin with the lower end of seat connection sheet, and the upper end of seat connection sheet and the lower part of upper joint connect into and can turn Dynamic structure；Joint spring and joint gear are equipped between upper joint and hypozygal, joint spring, which compresses joint gear, makes joint Gear mutually engages to form fixed structure with upper joint and hypozygal；Joint gear is connected with the rope that returns the vehicle to the garage and knock off, and the rope that returns the vehicle to the garage and knock off is connected with It returns the vehicle to the garage and knock off block, so that joint gear is detached from upper joint or hypozygal and is formed the rotatable knot that returns the vehicle to the garage and knock off by block tension of the returning the vehicle to the garage and knock off rope that returns the vehicle to the garage and knock off Structure；Seat collapses under folded state, and seat down tube is mutually posted by together with seat upper tube, and seat tubes are posted by seat down tube Bottom surface.

Further, there is the fixing axle for installing joint gear, joint spring and joint gear in the hypozygal It is sheathed in the fixing axle, and joint spring is pressed in hypozygal by joint gear；Under the extruding of joint spring, joint tooth Simultaneously by upper joint, the tooth of joint gear engages to form upper joint under simultaneously with the tooth socket in upper joint and hypozygal wheel The fixed structure in joint.

Further, in the joint gear be equipped with for return the vehicle to the garage and knock off rope across rope pass through hole, return the vehicle to the garage and knock off rope passed through from the rope Hole passes through joint gear and takes up on joint gear, and front end and the hypozygal of the rope that returns the vehicle to the garage and knock off are connected and fixed.

Further, the front end of the rope that returns the vehicle to the garage and knock off has a columned rope gland, and the rope that returns the vehicle to the garage and knock off passes through the rope gland It is stuck in hypozygal and forms a fixed connection structure with hypozygal, can realize Fast Installation and dismounting.

Further, the block of returning the vehicle to the garage and knock off is in the seat down tube, and the rope that returns the vehicle to the garage and knock off penetrates and return the vehicle to the garage and knock off from seat down tube block Connection is so convenient for returning the vehicle to the garage and knock off from the bottom up.

Further, a rope card division is equipped in upper joint, rope card division is stretched out towards hypozygal side, will return the vehicle to the garage and knock off rope downward Joint direction is ejected to the position flushed with joint spring end, in this way can be successfully convenient for returning the vehicle to the garage and knock off rope after block of returning the vehicle to the garage and knock off is cocked Joint gear is pressed into hypozygal.

When seat unfolded state, joint gear 3 is caught in the tooth of upper joint 4 and hypozygal 1 simultaneously under the effect of joint spring 2 In slot so that lower articular is in fastening state.When returning the vehicle to the garage and knock off, block 8 of returning the vehicle to the garage and knock off up is pulled, drives 7 movement of rope of returning the vehicle to the garage and knock off.It returns the vehicle to the garage and knock off The rope gland of rope 7 is fixed on motionless in the tooth socket of hypozygal, and can joint gear 3 ShiShimonoseki be pressed onto when the rope that returns the vehicle to the garage and knock off is straightened In the gear grooved of section 1, joint gear 3 is detached from the tooth socket of upper joint 4, and lower articular fastening state disappears.It pulls to return the vehicle to the garage and knock off in holding and pull The state of block 8 up pushes away seat down tube 9, and seat skeleton drives seat iron plate 5 and seat tubes 6 to fold by four-bar linkage structure, directly It reclines completely to seat down tube and seat upper tube.When seat is unfolded, by the reverse operating for the process of returning the vehicle to the garage and knock off, will finally return the vehicle to the garage and knock off block It putting down, joint gear is pressed back under the action of joint spring while engaging with the tooth socket of the tooth socket of upper joint and hypozygal, Form fixed structure.

The utility model is pulled by seat down tube, the rope that returns the vehicle to the garage and knock off, hypozygal, upper joint, joint gear, joint spring and returning the vehicle to the garage and knock off The mutual cooperation of the components such as block acts, and by returning the vehicle to the garage and knock off, block tenses joint spring, so that joint gear is detached from upper joint and engages, real Existing seat down tube all can be to realize to fold or be unfolded by ganged movement with rotary folding, other components, without manually Individually operated, easy to operate, time saving and energy saving, operation can be completed in one hand, is very beneficial for old man and women uses, fold folding State lower volume is small easy to carry.In addition, using the seat structure of separate type, in vehicle frame or impaired seat, replacement can be passed through Wherein one realizes its functional rehabilitation, more saves cost.
