Detailed Description

The technical scheme of the invention is described in detail below with reference to the accompanying drawings and the detailed description.

As shown in fig. 1-3, the present invention provides, in a preferred embodiment, a stent comprising: the device comprises a first positioning plate 1, a second positioning plate 11, a base 2, a supporting rod 3 with one end fixedly connected with the base 2, and a connecting sheet 4 arranged at the tail end of the supporting rod 3. The center of the base 2 is provided with a first ball joint 21. The first ball joint 21 comprises a screw 211, and the first positioning plate 1 and the second positioning plate 11 are sleeved on the screw 211. The other end of the supporting rod 3 is connected with the connecting sheet 4 through a second spherical joint 31.

Referring to fig. 3, the second positioning plate 11 is disposed below the first positioning plate 1, an opening is disposed between the first positioning plate 1 and the second positioning plate 11, and an internal thread is disposed in the opening to cooperate with the screw 211 of the first ball joint 21. The bracket of the invention has two different installation methods according to the installation environments. The first case is that the wall surface has been pre-provided with threaded openings using expansion screws. When the bracket is installed on a preset hole of a wall surface, the screw 211 is screwed into a preset position of the hole of the wall surface, then the first positioning plate 1 is rotated to a position contacting the wall surface, and the second positioning plate 11 is screwed to abut against the first positioning plate 1. The area of the first positioning plate 1 is preferably larger than that of the second positioning plate 11. At this time, the first positioning plate 1 corresponds to a spacer formed as the second positioning plate 11, and a relatively large area of the first positioning plate 1 can disperse the pressure of the second positioning plate 11 on the mounting surface, thereby preventing the bracket from being swayed laterally. The second case is where the stage or scenery has been provided with trusses of steel construction. When the bracket of the present invention is mounted to the truss, the first positioning plate 1 is first unscrewed and the second positioning plate 11 is held on the screw 211. The open end of the screw 211 is inserted into a preset mounting hole on the truss, and the first positioning plate 1 is sleeved on the screw 211 from the other side of the truss. The first and

second positioning plates

1 and 11 are then screwed together in opposite directions to clamp the truss. When the angle of the bracket is freely adjusted after the arrangement, the first locating plate 1 and the second locating plate 11 can firmly clamp the truss, and the retaining screw 211 is not easy to loose.

The second positioning plate 11 preferably has an outer wall with at least two planes. More preferably, six flats are provided so as to form a nut-like outer surface structure. So designed, when installing, it is convenient to screw the second positioning plate 11 by using a wrench. The second positioning plate 11 is preferably stepped, and the side of the second positioning plate 11 with a larger radius is tightly attached to the lower surface of the first positioning plate 1, and the outer surface of one end with a smaller radius is provided with a hexagonal nut shape.

Referring to fig. 2 to 4, the base 2 has a shape of a disk with a concave middle, and a receiving cavity 213 is provided in the middle of the base 2. The receiving chamber 213 is connected to the base 2 by a connecting rib 214. The connection ribs 214 are arranged non-radially, preferably in a spiral shape extending in the circumferential direction of the receiving chamber 213. So configured, the connecting rib 214 is formed as a through hole with a gradual relative distance from the base 2. The base 2 is preferably rotated by adjusting the mounting angle of the bracket of the present invention. When the bracket mounting angle of the present invention is adjusted by rotating the base 2 with the multi-jaw mounting tool, each jaw of the multi-jaw tool is inserted into the through hole, so that the tool can be caught without slipping off easily. In addition, the non-radially arranged connecting ribs according to the invention, in contrast to radially arranged connecting ribs, also prevent the connecting ribs from being broken off by excessive torque during the adjustment of the angle. If necessary, the tool schematic diagram required for adjusting the screwing is identified through the related sticker, so that the support rod 3 is prevented from loosening and dislocation caused by frequent rotation of the adjustment angle when a worker directly holds the support rod 3.

A first ball joint 21 is provided in the accommodation chamber 213. The upper portion of the accommodation chamber 213 is provided with a cover plate 212, and the cover plate 212 is fixed to the accommodation chamber 213 by bolts, thereby locking the first ball joint 21 in the accommodation chamber 213.

The support rods 3 are fixedly connected to the edge of the base 2, and the base 2 is formed in a shape of a disk with a concave middle, so that the support rods 3 form a predetermined opening angle with each other when being arranged along the edge far from the center of the base 2. In this way, the support rod 3 is formed in a horn-like radial form, so that the contact area between the end of the support rod 3 and the object to be supported can be enlarged. One end of the support rod 3 may be connected to the base 2 in various manners. For example, an internal thread is arranged in a through hole on the base 2, an external thread is arranged at the tail end of the supporting rod 3, and the internal thread of the through hole is in fit connection with the external thread at the tail end of the supporting rod 3. Alternatively, a fixed connection is used, such as a support rod 3 welded to the base 2. Or, an internal thread is arranged in the through hole on the base 2, an external thread is arranged at the tail end of the supporting rod 3, the supporting rod 3 is inserted into the through hole of the base 2, and the open end of the supporting rod 3 is screwed by a bolt.

Referring to fig. 5, the other end of the support rod 3 is provided with a second ball joint 31, and an internal threaded hole is provided in the center of the second ball joint 31. One end of the connecting sheet 4 is fixedly connected with the internal threaded hole of the second spherical joint 31 through a bolt, and the other end is connected with a mounting hole on the surface of the supported object through a bolt. Both ends of the connection piece 4 are formed at a predetermined angle. The connecting piece 4 is preferably L-shaped and is provided with a through hole at each end. The ends of the bracket can be kept horizontal by the combined action of the second ball joint 31 and the connecting piece 4, thus adapting to the mounting surface of the supported object.

Those skilled in the art will appreciate that the material forming the stent of the present invention may be metal, high strength plastic, etc. The techniques for processing the above materials may employ conventional machining or injection molding or 3D printing techniques, and the present invention is not limited thereto.

Referring back to fig. 1, the stand of the present invention can be used for a projector 5 having screw holes on a housing, however, it will be understood by those skilled in the art that the stand of the present invention can also be used for other devices having screw holes on a housing, such as a light-following lamp, stage lamp, etc. The technical advantages of the invention can be utilized to achieve the technical effects of convenient installation and angle adjustment.

The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
