Abstract

The utility model relates to a backrest regulating mechanism for children's carriages, which comprises a casing and a cover plate, wherein the casing is fixed with the cover plate; an inner cavity of the casing is provided with a locking block of which both sides are processed with teeth; the locking block can displace from left to right; the tooth side of the locking block and the inner wall of the casing are formed into an inclined installation clearance of a mesh belt; both sides of the inclined installation clearance are symmetric; a long round hole of the locking block is provided with a press key with the combination of an inclined plane; the press key can push the displacement of the locking block; a spring which can make the locking block reset is arranged between the locking block and the casing. The locking block can be displaced through operating the press key so as to change the variation of the installation clearance of the mesh belt. Thus, the mesh belt is engaged or loosened. When the mesh belt is loosened, the utility model can freely carry out slide regulation along the mesh belt. The utility model has the advantages of novel design and structure, simple structure and convenient operation. Besides, the utility model can realize the stepless regulation of a backrest from 110DEG to 170DEG and meet the requirement of state conversion from a sitting posture to a sleeping posture for a child.

Description

Bassinet Back Modulating Mechanism

Technical field

The utility model relates to Bassinet Back Modulating Mechanism, especially realizes the backrest adjustment mechanism of adjusting by ribbon.

Background technology

Along with growth in the living standard, perambulator is as the high consumption of Modern Family, very universal, though be the only-child, mostly family all wants to purchase perambulator and is the own more comfortable growth environment of children's creation, and backrest adjustment is exactly to be transformed into the prone position state promptly from 110 °～170 ° angular adjustment needs and design-calculated in order to satisfy child by sitting posture.The backrest adjustment of prior art is such: be provided with intermediate rod in the backrest back, the intermediate rod middle part connects top rod, two ends and the adjustment piece interlock of being fixed in the band saw dentation on both sides, seat, and compress by spring force, when needing to regulate backrest angle, pull top rod, overcome spring force and make the two ends of intermediate rod enter another adjacent occlusal position from an occlusal position simultaneously, the backrest inclination angle is regulated, the defective of this structure has: 1. structure more complicated, resistance is big during operation, inconvenience; 2. have only 3～4 owing to adjust the gear of piece, adjusting angle also is limited in 3～4 grades; Body weight pressure when 3. intermediate rod is sat by child to crouch is very easy to cause distortion asymmetric, causes the intermediate rod two ends to reach desirable occlusal position simultaneously and can not regulate.

Summary of the invention

Technical problem to be solved in the utility model is to overcome the defective of prior art and a kind of simple in structure, easy to operate, Bassinet Back Modulating Mechanism that backrest is regulated arbitrarily in 110 ° to 170 ° scopes is provided.

Technical matters of the present utility model is finished by following technical solution.

A kind of Bassinet Back Modulating Mechanism, it is characterized in that this regulating mechanism comprises housing fastened to each other and cover plate, but the housing inner chamber is provided with the locking block that both sides are processed with the left and right displacement of tooth, locking block tooth limit and inner walls form bilateral symmetry bevelled ribbon assemblage gap, be provided with the inclined-plane in the slotted hole of locking block in conjunction with the button that can promote the locking block displacement, also be provided with the spring that locking block is resetted between locking block and the housing.

Be respectively equipped with chimeric groove and protruding button the mutually on the both sides faying face of described housing and cover plate.

Described cover plate inboard is provided with the guide-localization post that matches with the activity of button endoporus.

The small end of described housing and cover plate is provided with the protecting sleeve with ribbon perforation that coincide with its shape.

Compared with prior art, the utility model makes the locking block displacement by operating buttons, and form the ribbon assemblage gap and change, or interlock or loosen, can on ribbon, any slippage regulate arbitrarily when loosening, it is novel, and is simple in structure, easy to operate, can realize step-less adjustment between 110 °～170 ° on the backrest, not influenced by gear, satisfy any state exchange needs of child from the sitting posture to the prone position, avoided the deformation of member and cause can't regulate drawback.

Description of drawings

Fig. 1 is the utility model sectional structure scheme drawing.

Fig. 2 removes upward view behind cover plate and the protecting sleeve for Fig. 1.

Fig. 3 is the shape assumption diagram that the utility model and ribbon are installed one.

The specific embodiment

Below in conjunction with above-mentioned accompanying drawing embodiment the utility model is described further again.

Referring to Fig. 1-3, Bassinet Back Modulating Mechanism is used for the backrest inclination angle to be regulated, be connected on the ribbon 16 of Back of perambulator back, ribbon does not seal two ends and fixes with the push rod of perambulator both sides respectively, the regulating mechanism that connects ribbon is positioned at the backrest back and is convenient to adult's operation, regulate the back and conflict on the backrest back, osed top two ends ribbon is not built-in by the cladding of perambulator decorative cover cloth.It comprises housing fastened to each other 3 and cover plate 5, and the erection column 15 of housing inner chamber and mount pad 12 is respectively equipped with mutual chimeric groove 10 and the protruding (not shown) of buckleing simultaneously as the screw retention place that is connected cover plate 5 on the faying face of the both sides of housing and cover plate.The cover plate inboard also is provided with guide-localization post 8.

Housing 3 inner chambers are provided with locking block 7, these locking block both sides are processed with serrated teeth, are provided with the inclined-plane in the Long Circle hole, middle part 14 in conjunction with the button 2 that can promote the locking block displacement, and the button middle part is a blind hole, match with 8 activities of cover plate guide-localization post, make button when pressing, have good guidance quality.Be provided with spring 4 between locking block and the housing, this spring one end seat is in locking block side blind hole 6, other end seat is in the open slot 13 of mount pad 12, locking block 7 toothed edges and housing 3 inwalls form bilateral symmetry bevelled ribbon 16 assemblage gaps 11, spring has acted on jacking force all the time to locking block, this application force resets locking block, thereby make and inner walls between gap smaller, ribbon is by fastening, ribbon after the fastening just can't be regulated the angle of inclination of backrest, as wants to change the backrest inclination angle, and for example the baby becomes prone position by sitting posture, pass through operation push-button, the button that is pressed because of with the inclined-plane marriage relation of locking block, overcome spring force and make locking block be pushed to the right (Fig. 1), this moment, locking block became greatly with the inner walls gap, ribbon is triped can regulate slippage, this is adjusted in and is step-less adjustment in 110 °～170 ° scopes of predetermined angular, and after waiting to loosen button, locking block resets under action of the spring, make the ribbon gap smaller, locking block is the fastening ribbon again.

Housing 3 of the present utility model is provided with the protecting sleeve 1 with ribbon perforation 9 that coincide with its shape with the small end of cover plate 5, in order to avoid ribbon drawing crack housing.
