Description

Corner connecting device for connecting frame

The new type is related to articles used in door frames or window frames, especially a corner joint device for connecting frames.

Press, the frame A such as door frame or window frame will be joined at the corner by a corner device. Common corner devices such as angle iron B as shown in Figure 1 or L-shaped connector made of aluminum alloy in Figure 2 Angle device C.

The cross bars and straight bars of the door frame or window frame are assembled through the above structure; however, the conventional structure has the following problems:

1. For the angle iron B in Figure 1, the structure of the angle iron B is formed by stamping an iron sheet. It can be understood that the forming size is difficult to control, and the thickness of the angle iron B is relatively thin, the overall structure strength is low, and it is easy to deform and break. .

2. Taking the L-shaped angle joint device C in Fig. 2 as an example, when the L-shaped angle joint device C is bent inward due to force during assembly, the shear stress generated will break toward the direct position due to insufficient toughness.

How to improve the lack of customary structure is a problem that the relevant industry actively solves.

The main purpose of the present invention is to provide a corner joint device for connecting the frame, which is characterized by reducing the weight of the corner joint device and can achieve the effect of lightweight frame.

The intersection of the horizontal support rod and the straight support rod is provided with a through circular slot hole. The circular slot hole increases the toughness of the horizontal support rod and the straight support rod. When the rod and the straight support rod are bent inward, it is not easy to deform or break; and the horizontal support rod and the straight support rod are provided with a plurality of hollow grooves to reduce the overall weight.

In the embodiment of the present invention, the frictional contact surfaces have a wavy appearance.

In the embodiment of the present invention, the frictional contact surfaces have a sawtooth appearance.

In the embodiment of the present invention, the hollow grooves have a trapezoidal appearance.

Through the above description, the features and effects of the present invention are briefly described as follows:

1. The new type solves the lack of structural strength and precision of conventional angle irons, and greatly reduces the structural weight through circular slot holes and hollow grooves.

2. The new type solves the lack of excessive weight and insufficient toughness of the L-shaped angle joint device, and avoids deformation or even fracture due to force.

3. The new structure reduces unnecessary weight of the frame, and does not affect the function and strength of the structure.

As shown in Figures 3 to 6, the corner joint device of the new type of connecting frame includes: a body 100, the cross section of the body 100 is approximately a 90-degree L-shaped rigid structure, and the body 100 includes a horizontal strut 10 With the straight support rod 20, the outer edges of the horizontal support rod 10 and the straight support rod 20 respectively have a friction contact surface 11, 21, as shown in Figs. 3 and 4, the aforementioned friction contact surfaces 11, 21 have a sawtooth shape. In appearance, the frictional contact surfaces 11, 21 can increase the contact area of the contact frame A; in addition to the zigzag shape as shown in Figs. 3 and 4, a wavy shape can also be selected.

As shown in Figures 3 and 4, the intersection of the horizontal support rod 10 and the straight support rod 20 is provided with a penetrating circular slot hole 30. The circular slot hole 30 increases the gap between the horizontal support rod 10 and the straight support rod 20. Toughness, when the horizontal strut 10 and the straight strut 20 are bent inward, they are not easily deformed or broken.

As shown in Figures 3 to 6, the horizontal support rod 10 and the straight support rod 20 are provided with a plurality of hollow grooves 12, 22 to reduce the overall weight. As shown in Figures 3 to 6, the aforementioned hollow grooves 12, 22 are formed The appearance of a triangle can also take on a trapezoidal shape as shown in Figure 7.

According to the design concepts shown in Figs. 3 to 6, the present invention can be implemented in the following modes:

As shown in FIG. 8, the main body 200 is composed of a transverse support rod 10 and a straight support rod 20; the outer edges of the transverse support rod 10 and the straight support rod 20 respectively have a serrated friction contact surface 11, 21 The junction of the aforementioned horizontal support rod 10 and the straight support rod 20 has two symmetrical trapezoidal grooves 30A, and the function of the aforementioned trapezoidal groove 30A is the same as that of the circular slot hole 30 of FIGS. 3 to 6, allowing the horizontal support The rod 10 and the straight rod 20 are not easily deformed or broken; the same above-mentioned horizontal rod 10 and the straight rod 20 are also provided with a plurality of hollow grooves 12 and 22, which can also achieve the effect of reducing weight.

Based on the above description, the features of the present invention are: 1. After assembly, the friction contact surfaces 11 and 21 can contact the frame A to achieve a good stopping effect; 2. The assembly method is basically the same as that of a general angle joint device or an angle iron. It is not complicated; 3. When the horizontal support rod 10 or the straight support rod 20 of the main body 100 is bent inward through the circular slot hole 30, it is not easy to deform or break; 4. The hollow grooves 12, 22 reduce the overall weight .

In summary, the new structure has never been seen in books or publicly used, and it is in compliance with the requirements of a new patent application. I sincerely ask Jun Bureau to approve the patent as soon as possible. I really pray.

If you need to clarify, the above are the technical principles immediately used in the implementation of the new model. If the changes made in accordance with the concept of the new model do not exceed the spirit covered by the specification and drawings, All should be within the scope of this new model, and should be combined with Chen Ming.
