Abstract

The utility model relates to a baby cart. Integrally-formed joint holes with equidistance and equal diameters are formed on plastic connection sleeve columns of both sides of the utility model, and each joint hole comprises a smooth bottom closing hole and hollow protruded column holes which are alternately arranged. The sleeve column can be assembled in a U-shaped rigid corner bracket after tenoned into a proper length, and then is positioned by end positioning covers. Inlay-buckle mortises of the positioning cover are tenoned and connected with tenon pieces of another U-shaped rigid corner bracket with the same structure, and threading hurdles in positioning holes form a cart frame body.

Description

Baby cart

The utility model relates to a kind of perambulator.

General perambulator commonly used, it roughly is divided into wooden and aluminum pipe frame two classes, and the production method of wooden car support body is to be drilled with several isometrical, equidistant holes on main car framework, vertically disposed rod hurdle frame is placed through each hole finishes combination; But in manufacturing process, must calculate bore position earlier and just can set up rod hurdle frame, when if drilling technique has deviation slightly, just assembly as scheduled, not only add heavily to the difficulty of the work, even each hole also can whether fully vertical or be offset crooked because of drill bit if processing cutting angle, causes and produce hole size and differ, and the rod hurdle frame that causes at last being worn becomes flexible easily, rocks; Most importantly, material is to be introduced by the other places, and then can increase cost of manufacture.Make for ferrous material, though can easily obtain material, equally very big for the difficulty of boring work programme, even must make unlikely loosening the rocking of reinforcement hurdle frame with the spot welding mode again; Like this, increase production process on the contrary, the deviation that is produced in the time of can not solving boring effectively.

The purpose of this utility model is to provide a kind of perambulator that can overcome above-mentioned shortcoming.

It is to realize like this that order of the present utility model is stated purpose, a kind of perambulator promptly is provided, but being attached at plastics at its both sides joggle connects on the sleeve column, be shaped on one-body molded equidistant, isometrical conjugate foramen, conjugate foramen is divided into smooth back cover hole and saturating empty protruded stigma hole, it is by compartment of terrain setting mutually, be positioned at Qian shape rigidity corner bracket both sides end and be provided with the location lid, and buckle tongue-and-groove, clamping stagnation point arranged, cooperate the tongue-and-groove, the clamping stagnation groove that are provided with in the tenon sheet, assembly constitutes normalized uniform distances conjugate foramen, utilizes the hole to place the hurdle and is configured to main body of vehicle frame.

The material that perambulator of the present utility model adopts and be easy to get, can one machine-shaping, its bearing capacity is good, makes simple and easyly, assembling is convenient, can not rock to get loose, stability by force, practicality is good.

Below in conjunction with accompanying drawing, embodiment of the present utility model is described, wherein:

Fig. 1 is the three-dimensional exploded view of the utility model perambulator;

Fig. 2 for the utility model perambulator but close cutaway view;

Fig. 3 is the embodiment scheme drawing of the utility model perambulator.

At first, see also Fig. 1, perambulator car body of the present utility model is respectively equipped with:

Several plastics connect sleeve column 1, it is for being the suitable length bars of " protruding " font, its upper surface leaves that an equidistant compartment of terrain is arranged and the isometrical ellipticity conjugate foramen 11 of size and one-body molded, wherein conjugate foramen 11 is divided into smooth back cover hole 111 and saturating empty protruded stigma hole 112 apart from one another by the ground setting, on the two avris fragment position, be shaped on the buckle 12 and tongue-and-groove 13 or plane 14 bodies of joggle effect.One Qian shape rigidity corner bracket 2 cooperates plastics to connect sleeve column 1 moulding and also is one " protruding " word shape, by inside prominent bar edge 21 is constituted a slideway corner bracket on the end face.At corner bracket 2 limit ends, other is shaped on the location lid 3 of the flat square effect of transferring together, and the buckle tongue-and-groove 31 that 3 outmost surface have T-shaped shape cover in the location, and each prominently establishes a clamping stagnation point 311 in the both sides at the end, is installed with a through hole 32 in the centre, locatees to wear screw 3A.And cover the 3 tenon sheets 4 that play switching flat square effect with the location, then be designed to T shape caulking groove 41, and both sides respectively is arranged with a clamping stagnation groove 411 bottom it, be fixed on another Qian shape rigidity corner bracket 1 ' on.

Have again, plastics are connect plane 14 that sleeve column 1 both sides are provided with and buckle 12 or tongue-and-groove 13 set and be attached to the suitable length size, put into U-shaped rigidity corner bracket 2 again and be subjected to 21 restrictions of bar edge, the plastics in both sides connect the planar section 14 of sleeve column 1, each encapsulation one location covers 3, and it is fixed by screw 3A; But the tenon sheet 4 of switching usefulness also locking makes its clamping stagnation point 311 that cover 3 buckle tongue-and-groove 31 and bottom thereof by the location overlap the caulking groove 41, the clamping stagnation groove 411 that are embedded in tenon sheet 4 and mutually combines and become a plane framework in another U-shaped rigidity corner bracket 2 ' ora terminalis; So; connect by plastics more equidistant, the isometrical conjugate foramen of a scale 11 is set on the sleeve column 1; wear hurdle frame 5 one by one, as shown in Figure 2, because hurdle frame 5 is arranged in the conjugate foramen 11; and conjugate foramen 11 is divided into smooth back cover hole 111 and the saturating empty protruded stigma hole 112 that is provided with at interval; saturating empty protruded stigma can be strengthened the combination with hurdle frame 5, makes it more firm, so; on hurdle frame 5 tops, repeat to assemble the framework on a plane, finish a complete perambulator car body (as shown in Figure 3).This assembly production program is not only removed the manufacturing procedure of boring effectively from, shortens the assembly time, again because its to have a unified uniform distances conjugate foramen one-body molded, can assemble smoothly, but and utilize U-shaped rigidity corner bracket 2 reinforced plastics to connect the weight bearing of sleeve column 1.Simultaneously, cooperate with the hurdle frame 5 that matches, can prevent perambulator hand reversing and cause the hurdle frame to become flexible swag phenomenon unintentionally by oval-shaped conjugate foramen 11.

Claims

A kind of perambulator is characterized in that, but it be connected plastics at the both sides joggle and connect on the sleeve column, be shaped on integrally formed equidistant, isometrical conjugate foramen, conjugate foramen is divided into smooth back cover hole and saturating empty protruded stigma hole, it is by apart from one another by the ground setting; The location that is provided with that is positioned at Qian shape rigidity corner bracket both sides end is covered, and buckle tongue-and-groove, clamping stagnation point are arranged, and cooperates the tongue-and-groove, the clamping stagnation groove that are provided with in the tenon sheet; Assembly has normalized uniform distances conjugate foramen, utilizes the hole to place the hurdle and is configured to main body of vehicle frame.
