These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0042] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0043] Embodiment 1

[0044] Reference Figure 1 As shown, the present embodiment provides a method for preparing an integrated elbow base, comprising the following steps:

[0045] A1, provide a Figure 4 The straight circular tube 100 of equal diameter shown in the figure has a first tube section near its first end and a second tube section near its second end, and the first tube section and the second tube section are respectively reduced to obtain a tapered tube 200 with an outer diameter gradually reduced from the middle to both ends, as shown in FIG. Figure 5 As shown, the first pipe section 11 and the second pipe section 12 are both turned into tapered pipe sections;

[0046] Specifically, in this embodiment, the use of a tube shrinking machine for tube shrinking has the following advantages: the wall thickness is uniform in the straight tube state (as shown in FIG6(a)). After the tube shrinking process, in order to maintain the principle of conservation of mass, the reduced tube will form material accumulation, so that the wall thickness of the reduced tube will become thicker. As shown in FIG6(b), taking the first tube segment 11 as an example, the thickness of the tube wall of the first tube segment 11 gradually increases in the direction toward its outer end 111, which invisibly increases the strength of the tube. In addition, not only the material becomes thicker, but the length will also be appropriately lengthened. Therefore, when making a support base that requires strength, thinner materials can be used to achieve stronger strength requirements, and shorter materials can be used to achieve longer material requirements. Material costs can be greatly saved.

[0047] Further preferably, as shown in Fig. 9(a), Fig. 9(b) and Fig. 9(c), the tube shrinking machine comprises a main body 1 and a tube shrinking mold 2 which can rotate in the main body 1, the tube shrinking mold 2 is formed by splicing a plurality of (four in this embodiment) arc-shaped sheets 3, the tube shrinking mold 1 has an inner cavity 4 with a certain taper, and the tube shrinking machine can drive the tube shrinking mold 2 to rotate. During operation, the tube shrinking machine is started, the tube shrinking mold 2 rotates, and then the first tube segment or the second tube segment of the equal-diameter straight circular tube 100 is inserted into the inner cavity 4 of the tube shrinking mold 2, and the rotation of the tube shrinking mold 2 realizes the tube shrinking operation of the equal-diameter straight circular tube 100 to obtain a tapered tube 200.

[0048] A2, bend the middle part of the tapered tube 200 so that the first tube section 11 and the second tube section 12 form an angle with each other, thereby obtaining a tapered bent tube 10, as shown in FIG8(a).

[0049] Specifically, in this step, the bending method is the stamping bending in the prior art.

[0050] The first tube section 11 and the second tube section 12 are at an angle to each other, respectively forming two tube pins of the TV base.

[0051] A3, provide a connector 20, and assemble the connector 20 at the middle position of the tapered elbow 10, such as Figure 3 shown.

[0053] The connector 20 is fixedly inserted into the plug hole 101 through the plug post 21. It has the advantages of simple assembly structure and easy operation. Of course, it is not limited to this in other embodiments.

[0054] A4, foot pads 30 are respectively provided at the outer ends of the first pipe section 11 and the second pipe section 12 to obtain Figure 1 Finished product shown.

[0056] Furthermore, in this embodiment, the outer ends of the first pipe section 11 and the second pipe section 12 are also beveled to form an inclined end surface 13, and the two inclined end surfaces 13 are located on the same plane. This is to increase the support area of ​​the ground. Specifically, the bevel step is between step A1 and step A2, that is, Figure 5 Based on the bevel cutting, the Figure 7 The structure shown in FIG8(a) is then subjected to the bending step of step A2 to obtain the structure shown in FIG8(a). Of course, in other embodiments, the beveling step can also be performed between step A2 and step A4. If it is performed between step A2 and step A4, the beveling operation is more convenient and the error caused by the bending is eliminated.

[0057] Of course, in other embodiments, the outer ends of the first tube section 11 and the second tube section 12 may not be beveled, as long as the bottom of the foot pad 30 is set to an inclined bottom surface.

[0059] Specifically, the wall thickness of the first pipe section 11 and the second pipe section 12 gradually increases in the direction toward the outer end, and are prepared by the above-mentioned pipe shrinking machine, which can effectively enhance the supporting strength.

[0060] Specifically, the connector 20 is a plastic connector, a metal connector, a plastic-coated metal connector, etc., which can be selected according to actual needs.

[0061] Specifically, the connection structure of the connector 20 and the elbow 10 is as follows: the connector 20 is provided with a plug-in column 21, a plug-in hole 101 is provided in the middle of the tapered elbow 10, and the connector 20 is fixedly inserted in the plug-in hole 101 through the plug-in column 21. It has the advantages of simple connection structure and easy assembly. Of course, in other embodiments, the connection structure of the connector 20 and the elbow 10 is not limited to this, and can also be fixed by bolts, etc.

[0062] Specifically, the outer ends of the first pipe section 11 and the second pipe section 12 are also beveled to form an inclined end surface 13, and the inclined end surfaces 13 of the first pipe section 11 and the second pipe section 12 are located on the same plane to increase the supporting area of ​​the ground.

[0063] Specifically, the foot pad 30 is integrally formed on the outer ends of the first pipe section 11 and the second pipe section 12 by injection molding, which is easy to prepare and has good uniformity.

[0064] This solution adopts an integrated tube body, that is, the two tube legs used for support are bent from a tube body, which saves the steps of sequential assembly and simplifies the process flow; it also avoids the defect that the bottoms of the two tube legs are not in the same plane during the assembly process and cannot contact the support surface well; the assembly efficiency is high and the qualified rate is high. At the same time, the first tube segment 11 and the second tube segment 12 as the tube legs have a certain taper, so that the product has a greatly improved visual aesthetic effect without affecting the support strength, making the product more competitive.
