This technology involves an upper and lower swing arm positioned between an upper support plate and a base plate, with a sealing device between the upper and lower swing arms, a stainless steel sliding plate between the lower swing arm and the base plate, and a pre-embedded steel plate below the base plate. A hinge shaft is located at the center of the upper and lower swing arms. This technology offers advantages such as uniform force distribution, flexible rotation and sliding, easy maintenance, low repair costs, and long service life. However, this technology has the following problems.

[0004] When a ball joint hinge shaft support needs to be rotated during the vertical rotation of a space frame, it is difficult to protect the rotating contact parts during the continuous rotation, which leads to damage to the rotating contact parts of the ball joint hinge shaft support.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] like Figure 1 - Figure 4 The invention relates to a ball joint hinge support suitable for vertical rotation of space frame structures. This ball joint hinge support is equipped with a protective component. The protective component can protect the positions of the inclined support block 7 and the support 1, so that the contact parts between the hinge seat 4 and the support 1 are protected when the hinge seat 4 rotates, thus achieving damage prevention operation and providing a more excellent damage prevention effect. The specific structure of the protective component is as follows.

[0022] Example 1: In this embodiment, as Figure 1 - Figure 3 As shown, a hinge shaft 2 is rotatably mounted on the upper surface of the support 1, and a hinge seat 4 is fixed to the top of the outer wall of the hinge shaft 2. Protective components are provided on both sides of the outer wall of the hinge seat 4. These protective components protect the contact area between the hinge seat 4 and the support 1. The protective components include: a mounting cylinder 5 fixed to the upper surface of the hinge seat 4; a protective corner pad 6 fixed at one corner of the hinge seat 4; a diagonal support block 7 fixed on one side of the hinge seat 4 and above the protective corner pad 6; and a protective inclined pad 8 fixed to the lower surface of the inclined support block 7. Both the protective inclined pad 8 and the protective corner pad 6 are slidably connected to the support 1. The vertical cross-sectional shape of the protective corner pad 6 is arc-shaped, and both the protective inclined pad 8 and the protective corner pad 6 are made of rubber. The vertical cross-sectional shape of the diagonal support block 7 is triangular, and the vertical cross-sectional shape of the protective inclined pad 8 is rectangular.

[0023] In this embodiment, as Figure 2 As shown, the outer wall of the hinge shaft 2 and near both ends are provided with limiting rings 3, both of which are fixedly connected to the support 1. Both the hinge shaft 2 and the hinge seat 4 are rotatably connected to the limiting rings 3, and the two limiting rings 3 are symmetrically arranged about the hinge seat 4. By rotating the hinge seat 4 between the two limiting rings 3, the hinge shaft 2 can perform a rotational hinge operation on the inner wall of the two limiting rings 3, improving the stability of the hinge seat 4 during rotation.

[0024] In this embodiment, as Figure 1As shown, a support plate 9 is fixed to the bottom of the support 1. Mounting holes 10 are provided on the inner wall of the support plate 9, near its four corners. The mounting holes 10 are arranged in a rectangular pattern, and each mounting hole 10 has a circular cross-section. Pre-embedded bolts are inserted into the mounting holes 10 to fix the support plate 9, which supports the support 1 and improves its stability.

[0025] In this embodiment, a non-damaging hinge support for a ball joint in a vertically rotating space frame is used. A support plate 9 is fixed by inserting pre-embedded bolts into the mounting holes 10. The support plate 9 supports the support 1, and the support 1 supports two limiting rings 3. By rotating the mounting cylinder 5, the mounting cylinder 5 drives the hinge seat 4 to rotate. The hinge seat 4 rotates between the two limiting rings 3, and simultaneously drives the hinge shaft 2 to rotate. The hinge shaft 2 can perform a rotational hinge operation on the inner walls of the two limiting rings 3. The hinge seat 4 drives the protective corner pad 6 to rotate, ensuring... The corner protection pad 6 is located at the top corner of the support 1. This allows the corner protection pad 6 to be positioned between the hinge seat 4 and the support 1, providing buffer protection for the contact area between the hinge seat 4 and the support 1. At the same time, the hinge seat 4 drives the inclined support block 7 to rotate, and the inclined support block 7 drives the protective inclined pad 8 to rotate. The protective inclined pad 8 is attached to the inclined side surface of the support 1, thereby providing protection for the position between the inclined support block 7 and the support 1. In this way, the contact area between the hinge seat 4 and the support 1 is protected during the rotation process, achieving damage prevention.

[0026] Example 2: In this embodiment, as Figure 3 - Figure 4 As shown, inclined blocks 11 are fixed on both sides of the support 1 and below the inclined block 7; a support strip 12 is installed on one inclined surface of the inclined block 11, and a support block 13 is installed on the top of the support strip 12. The support block 13 and the inclined block 11 are both fixedly connected to the support strip 12. A pad strip 14 is fixed on the upper inclined surface of the support block 13, and the pad strip 14 is in contact with the hinge seat 4 by compression.

[0027] In this embodiment, the ball node hinge support for vertical rotation of a space frame is applied without damage. The support 1 supports the inclined block 11, the inclined block 11 provides support force to the support bar 12, and the support bar 12 supports the support block 13. The support block 13 supports the pad strip 14, and the pad strip 14 contacts and protects the hinge seat 4. In this way, the support block 13 and the hinge seat 4 are protected by the pad strip 14, which also protects the inclined surface of the hinge seat 4.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
