Abstract

The utility model discloses a baby carriage rear leg joint stabilizing mechanism and is mainly applicable to a connection position of a handlebar pipe and a rear leg pipe of a baby carriage. The baby carriage rear leg joint stabilizing mechanism comprises the handlebar pipe, a rear leg pipe connection member, the rear leg pipe and a rear leg joint, wherein the rear leg connection member is hinged to the rear leg joint through a hinge fulcrum. The baby carriage rear leg joint stabilizing mechanism is characterized in that an arc hole using the hinge fulcrum as a circle center is added to the rear leg connection member, and a connection rivet which penetrates the rear leg joint to be assembled in the arc hole is added to the rear leg joint. By means of the arc hole and the connection rivet matched with the arc hole, use stability between the rear leg connection member and the rear leg joint is greatly improved, and the hinge fulcrum does not bear large support pressure while bearing rotation, so that connection and rotation are more reliable.

Description

Perambulator rear foot joint stabilizing mechanism

Technical field

The utility model relates to the stable connection mechanism between a kind of product adjacent component, specifically refers to perambulator rear foot joint stabilizing mechanism.

Background technology

At present; in perambulator, use or folding carrying for the ease of the expansion of whole perambulator; conventionally can between the handle pipe of perambulator and rear foot tube, articulated structure be set; by rear foot tube end relative to the rotating of handle pipe, the expansion that can realize between handle pipe and rear foot tube is used or closes up folding.But, comparatively traditional articulated structure is all that rear foot attaching parts is installed in handle pipe between the two, at rear foot tube end, rear foot joint is installed, then between rear foot attaching parts and rear foot joint, arrange hinged to be articulated and connected, this hinged in perambulator use procedure not only as the connection of rotating parts between rear foot attaching parts and rear foot joint, also be the stabilizing means supporting as between rear foot attaching parts and rear foot joint, it bears very large pressure when launching or be folding in the relative rear foot of rear foot attaching parts joint, often easily cause the loosening or impaired of the hinged point in this place, thereby affect stability in use.

Summary of the invention

Technical problem to be solved in the utility model is to overcome the defect of prior art and the perambulator rear foot joint that a kind of connection of rotating is reliable, stability in use is good stabilizing mechanism is provided.

Technical matters of the present utility model is achieved through the following technical solutions:

A kind of perambulator rear foot joint stabilizing mechanism, comprise handle pipe and rear foot tube, rear foot attaching parts is installed in described handle pipe, described rear foot tube end is provided with rear foot joint, between described rear foot attaching parts and rear foot joint, being provided with hinged point is articulated and connected, on described rear foot attaching parts, be also provided with the arcuate socket taking hinged point as the center of circle, described rear foot joint is provided with through rear foot joint and is fitted in the connection rivet in described arcuate socket.

Described rear foot attaching parts one side is provided with the connecting strap of fan shape, and described hinged point and arcuate socket are all arranged on this connecting strap; Described end, rear foot joint is provided with two parallel outward extending connecting panels, and described connecting strap is inlaid between two connecting panels.

Described hinged point is to be equipped with hinge hole on rear foot attaching parts and rear foot joint, is connected with hinged rivet in this hinge hole.

Compared with prior art, the utility model is mainly between the rear foot attaching parts that is articulated and connected in formation and rear foot joint, to have additional to be arranged on the arcuate socket on rear foot attaching parts and taking hinged point as the center of circle and to be arranged on rear foot joint and through rear foot joint to be fitted in the connection rivet in arcuate socket, by being set, mutually equipped arcuate socket and connection rivet can improve the stability in use between rear foot attaching parts and rear foot joint, and it is hinged in bearing rotation, no longer bear larger abutment pressure, therefore make connection of rotating more reliable.

Detailed description of the invention

To elaborate again to the utility model embodiment by above-mentioned accompanying drawing below.

As shown in Fig. 1 ~ Fig. 5,1. handle pipe, 2. rear foot attaching parts, 21. arcuate sockets, 22. connecting straps, 3. rear foot tube, 4. rear foot joint, 41. connecting panels, 5. hinged point, 51. hinged rivets, 52. hinge holes, 6. connection rivet.

Perambulator rear foot joint stabilizing mechanism, is mainly used in handle pipe 1 and rear foot tube 3 connections of perambulator.

Described handle pipe 1 and rear foot tube 3 are the circular tube structure that light-weight metal is made, and in handle pipe 1, are installed with rear foot attaching parts 2 through rivet, and rear foot tube 3 ends are installed with rear foot joint 4 through rivet; Described rear foot attaching parts 2 and rear foot joint 4 are Plastic Parts.

Described rear foot attaching parts 2 one sides are provided with the connecting strap 22 that disjunctor extends, it is the fan shape of 90 ° that the profile of this connecting strap is angle, a straight flange of this fan shape connecting strap 22 is close to and is connected on rear foot attaching parts 2, and another straight flange and handle pipe 1 are just in time vertical positional relationship; On described connecting strap 22, be also provided with a hinge hole 52 and the arcuate socket taking hinge hole as the center of circle 21, adjacent two the straight flange intersections that are arranged on connecting strap 22 of this hinge hole 52, the adjacent setting of arc-shaped side of this arcuate socket 21 and connecting strap 22.

Described 4 ends, rear foot joint are provided with two parallel outward extending connecting panels 41, are embedded with the connecting strap 22 of rear foot attaching parts 2 between two connecting panels.Simultaneously, on two connecting panels 41, be also provided with hinge hole 52, and form hinged point 5 through the hinge hole 52 on two connecting panels 41 and connecting strap 22 successively by a hinged rivet 51, be that rear foot joint 4 is done hinged rotation by hinged point 5 relative to rear foot attaching parts 2, thereby form deployed condition or close up state; On two connecting panels 41, be also provided with one and be contained in the connection rivet 6 in arcuate socket 21 through connecting plate matched, when forming between rear foot joint 4 and rear foot attaching parts 2 after rotation, can slide along arcuate socket 21 by the connection rivet 6 that connecting panel 41 drives, therefore can better improve the stability in use between rear foot attaching parts 2 and rear foot joint 4.

The above is only preferred embodiments of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
