Description
Technical field
This utility model relates to the structure of a kind of perambulator, more specifically, it relates to a kind of Pram folding body frame structure for automotive.
Background technology
Rear wheel of baby carriage frame is the parts installing trailing wheel on perambulator, also it is topmost ground supports structure on perambulator, common rear wheel of baby carriage frame typically can not fold, perambulator whole height cannot be reduced, take up room bigger, as take perambulator drive to travel outdoors time, this kind of perambulator is difficult to pack into normal domestic use car, though load may interfere with the loading of other article, storage.nullFor this，Perambulator manufacturer develops vehicle frame foldable baby carriage，The utility model of such as Publication No. CN204895718U discloses the foldable chassis of a kind of perambulator on the 23rd in December in 2015，Including headstock assembly、Vehicle seat、Rear frame component、Bicycle beam and frame state locking mechanism，Described headstock assembly rear end is hinged with bicycle beam front end，Described Rear frame component front end is hinged with bicycle beam rear lower，Described vehicle seat is arranged on top in the middle part of bicycle beam，Described frame state locking mechanism includes securing rod、Spring、Deployed condition locking piece、Folded state locking piece，Described deployed condition locking piece and folded state locking piece are separately mounted to Rear frame component top，Described securing rod top hinged vehicle seat lateral surface，Spring is arranged on vehicle seat lateral surface and securing rod is drawn by spring toward lower left，The expansion lock slots that can block deployed condition locking piece is had in the middle part of described securing rod left side，Securing rod rear end is provided with the foldable locking hook that can block folded state locking piece.This utility model is owing to being improved frame state locking mechanism, and therefore structure is more reasonable, and easily fabricated and installation, and easy to use, it is more rapid convenient to operate.But this foldable chassis relies on the frame state locking mechanism exposed to realize the state after frame state changes to be kept, and parts are more, and this base part is less coordinated with perambulator self structure, affect the outward appearance of perambulator.
Utility model content
The locking piece that the existing more employing of frame for baby cart foldable structure exposes, affect the outward appearance of perambulator, for overcoming this defect, this utility model provides a kind of locking mechanism and preferably integrates with perambulator self assembling structure, keeps the Pram folding body frame structure for automotive that perambulator outward appearance is clean and tidy, coordinate.
The technical solution of the utility model is: a kind of Pram folding body frame structure for automotive, including longeron and the rear wheel frame of U-shaped, rear wheel frame is connected on longeron, rotating junction it is provided with between longeron and rear wheel frame, it is rotatably connected in the middle part of rear wheel frame on this rotating junction, between rear wheel frame and this rotating junction, is provided with rotary locking mechanism.Rear wheel frame can rotate around rotating junction, it is achieved folder function.Rotary locking mechanism can carry out state holding respectively when rear wheel frame is in expansion and folded state.
As preferably, described rotating junction includes fixing partly cuts open cylinder, removable partly cut open cylinder and two rib circles, fix and partly cut open cylinder, the removable cylinder that partly cuts open is all in semi-circular cylindrical, fixing partly cut open cylinder and be fixedly arranged on longeron, two rib snares are located on rear wheel frame, circumferentially arranged with the convex tendon that multiple tracks is parallel on rib circle, fix and partly cut open cylinder, the removable cylinder that partly cuts open is filled the span of a man's arms outside two rib circles, fix and partly cut open cylinder, removable partly cut open cylinder detachably connected one-tenth tubular, the spring catch tubing string of radial projection it is installed with on rear wheel frame, spring catch tubing string height is less than described fin height, spring catch tubing string is between two rib circles, fix and partly cut open cylinder, the removable cylinder that partly cuts open is provided with rib circle axial limit structure.Partly cuing open cylinder, the removable obvolvent partly cuing open cylinder, the cooperation between rib circle, spring catch tubing string, rib circle axial limit structure by fixing, rear wheel frame the most all can be limited, and circumference is the most rotatable.This rotating junction outward appearance rule, multiple functional.
As preferably, described rotary locking mechanism includes that unlocking button, spring catch and liner partly cuts open cylinder, liner partly cuts open cylinder and is located at and fixing partly cuts open cylinder, removable partly cut open between cylinder and rib circle, and with fixing partly cut open cylinder, the removable cylinder that partly cuts open removably connects correspondingly, spring catch is located in described spring catch tubing string, unlock button slip to be arranged on the removable barrel partly cuing open cylinder, the removable cylinder that partly cuts open partly cuts open with liner and is equipped with the perforation that position is corresponding on the barrel of cylinder, unlocks button, spring catch also corresponding with punch position.Along with rear wheel frame rotates, when spring catch arrives punch position, spring catch ejects, and is stuck in liner and partly cuts open the perforation aperture of cylinder, and rear wheel frame is locked out, and stops operating.When pressing unblock button, spring catch is pressed liner and is partly cutd open in cylinder by unblock button, releases locking, and rear wheel frame can be rotated further again.
As preferably, described spring catch tubing string is two, and two spring catch tubing strings are positioned on the same cross section in the middle part of rear wheel frame.The expansion of two the most corresponding rear wheel frames of spring catch tubing string and folded state, the spring catch in two such spring catch tubing string realizes the holding of rear wheel frame deployed condition and folded state the most respectively when ejecting.
As preferably, described rib circle axial limit structure is located at and fixing is partly cutd open cylinder and the removable end plates partly cuing open a two ends with being formed in one, end plates center be provided with rear wheel frame in the middle part of the adaptive semicircle orifice of external diameter.Fixing cylinder and the removable cylinder that partly cuts open of partly cuing open is when linking into an integrated entity, and end plates keep off in rib circle outer end, stop rib circle axially displaced, and then stop rear wheel frame axially displaced.
As preferably, fixing partly cut open cylinder, the removable cambered surface both sides of the edge partly cuing open cylinder are equipped with joint flange, engage flange and be provided with bolt fixing hole.Fixing partly cut open cylinder, the removable joint flange partly cuing open cylinder is affixed, then fastens with bolt, can by fixing partly cuing open cylinder, the removable cylinder that partly cuts open links into an integrated entity.
The beneficial effects of the utility model are:
Realize keeping while frame for baby cart folder function that perambulator outward appearance is clean and tidy, coordinate.Rotational structure and rotary locking mechanism in this utility model preferably combine, and will not be arranged on frame for baby cart by outer open country, thus keep that perambulator outward appearance is clean and tidy, coordinate.
