Abstract

A baby carriage is composed of two plastic sleeves with engaging holes at equal intervals and with a U-shaped rigid corner frame, two locating covers at both sides of said rigid corner frame, and two fastening tenon slots for connecting another tenon plate with same structure to said corner frame.

Description

The utility model relates to a baby carriage.

Generally, baby carriages are commonly used, which are roughly divided into two types: wooden and aluminum tube frames. The railings are placed in each hole to complete the assembly; however, in the production process, the drilling position must be calculated first before the wooden railings can be erected. If the drilling technology is slightly deviated, the assembly and combination will not be possible as scheduled, which will not only increase the difficulty of the work , and even each hole will be different in size due to whether the cutting angle of the drill bit is completely vertical or skewed, which will eventually cause the wooden railings to be worn to loosen and shake easily; the most important thing is that the material is made of The introduction from other places will increase the production cost. For the production of iron materials, although the materials can be easily obtained, the drilling process is also very difficult, and even the spot welding method must be used to prevent the reinforced fence from loosening and shaking; this will increase the production process, and it is not effective. It can effectively solve the deviation generated when drilling.

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

The purpose of this utility model is achieved by providing a baby carriage, which can be tenon-jointed on both sides of the plastic sleeve, and is formed with integrally formed joint holes with equal distances and diameters. The joint holes are divided into two parts: The flat bottom-sealed hole and the hollow protruding column hole are arranged at intervals. Positioning covers are provided at both ends of the square rigid corner frame, and there are embedded tenon grooves and clamping points, which match the tenon grooves and tenon grooves set in the tenon piece. The clamping grooves are assembled and combined to form standardized joint holes with the same spacing, and the holes are used to penetrate the hurdles to form the main body of the frame.

The baby carriage of the utility model adopts materials that are relatively easy to obtain and can be integrally processed and formed, and has good bearing capacity, simple manufacture, convenient assembly, no shaking and loosening, strong stability and good practicability.

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

Fig. 1 is the three-dimensional exploded view of the baby carriage of the present invention;

Fig. 2 is a cross-sectional view of the baby carriage of the present invention;

Fig. 3 is a schematic diagram of an embodiment of the baby carriage of the present invention.

At first, referring to Fig. 1, the stroller body of the present utility model is respectively provided with:

Several plastic socket posts 1, which are strips of appropriate length in the shape of a "convex", are integrally formed with elliptical joint holes 11 arranged at equal intervals and equal in size and diameter on the upper surface, wherein the joint holes 11 It is divided into a flat bottom cover hole 111 and a hollow protruding post hole 112 arranged at intervals from each other. On the side sections of both sides, there are embedded buckles 12 and mortise grooves 13 or flat surfaces 14 that act as tenon joints. A square rigid angle frame 2, cooperates plastics socket post 1 molding to also be a " convex " word shape, constitutes a slideway angle frame by the strip edge 21 that protrudes inwardly on the top face. At the side ends of the corner frame 2, a positioning cover 3 that is connected to the plane at right angles is also made. The outermost surface of the positioning cover 3 has a T-shaped embedded tenon and groove 31, and a sticking point is protruded on both sides of the bottom. 311, a through hole 32 is pierced in the middle to pass through the screw 3A for positioning. The tenon piece 4, which acts at right angles to the transfer plane with the positioning cover 3, is designed as a T-shaped slot 41, and a locking groove 411 is recessed on both sides of its bottom to be fixed on another square rigid angle frame. 1' on.

Furthermore, the plane 14 provided on both sides of the plastic sleeve 1 and the embedded buckle 12 or tongue and groove 13 are embedded and connected to an appropriate length, and then placed in the U-shaped rigid corner frame 2 and restricted by the strip edge 21, on both sides. The plane section 14 of the plastic socket column 1 is fitted with a positioning cover 3, which is fixed by a screw 3A; the tenon sheet 4 for the transfer can also be locked on the end edge of another U-shaped rigid angle frame 2', so that It consists of the embedded tenon groove 31 of the positioning cover 3 and the clamping point 311 at the bottom, which are embedded in the embedded groove 41 of the tenon piece 4, and the clamping groove 411 is combined to form a plane frame; in this way, the plastic connecting column 1 is provided with a large-scale equidistant and equal-diameter joint hole 11, and the hurdles 5 are pierced one by one. The flat bottom cover hole 111 and the hollow protruding post hole 112, the hollow protruding post can strengthen the combination with the hurdle 5 to make it more firm. In this way, a plane frame is repeatedly assembled on the top of the hurdle 5 to complete a complete The body of the stroller (as shown in Figure 3). This assembly production procedure not only effectively eliminates the drilling process and shortens the assembly time, but also can be assembled smoothly because of the uniform and uniform joint holes formed in one piece, and the U-shaped rigid angle frame 2 can be used to strengthen the plastic socket post 1 weight bearing. At the same time, the elliptical engaging hole 11 cooperates with the matched rail 5, which can prevent the hand of the stroller from being twisted unintentionally and cause the rail to loosen and shake.

Claims (1)

A baby stroller, characterized in that it can be tenon-jointed on both sides of the plastic connecting post, and is formed with integrally formed joint holes with equal distances and equal diameters. The joint holes are divided into flat bottom-sealed holes and hollow protrusion holes. They are arranged at intervals from each other; positioning covers are provided at both ends of the rectangular rigid angle frame, and there are embedded tenon grooves and clamping points, which match the tenon grooves and clamping grooves set in the tenon piece; the assembly combination has a standardized The holes are joined at the same spacing, and the holes are used to pass through the rails to form the main body of the frame.
