Description

Technical Field

[0001] The utility model relates to the technical field of film and television virtual engine shooting, in particular to a modular detachable steel bracket. Background Art

[0002] The existing product is an accessory used for the coordinate position and real-time movement control of specific objects during filming with virtual engines. The spatial tetrahedron formed by four positioning balls as endpoints is identified and marked due to its unique shape, and the steel bracket is identified as a specific object in the corresponding image during imaging. Usually, a one-piece steel bracket is used. The single positioning ball arrangement scheme cannot simultaneously provide positioning work for multiple objects in the imaging. It is also expensive, inconvenient to store, and easy to be damaged and deformed. The specific defects are: (1) the cost of mold production, materials, packaging, transportation, and maintenance is high; (2) the one-piece steel bracket only meets a single positioning ball arrangement scheme; (3) the four support rods of the one-piece steel bracket are prone to displacement and deformation after long-term use.

DETAILED DESCRIPTION

[0021] The present invention is further described in detail below in conjunction with the accompanying drawings, wherein the same parts are represented by the same figure numerals. It should be noted that the words "front", "rear", "left", "right", "up" and "down", "bottom" and "top" used in the following description refer to the directions in the drawings, and the words "inside" and "outside" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Design concept: By creating a new structural form that separates the base and support rod of the traditional integrated steel body bracket, and providing a variety of internal thread positions of the steel body base and support rod lengths, different arrangements of the positioning balls fixed on the top of the support rod can be realized. While greatly reducing the mold size and cost, it can also unlock the simultaneous operation of up to eight positioning objects during the same shooting time.

[0024] Example 1:

[0025] like Figure 1 and Figure 2 As shown, the technical solution provided by the utility model is a modular detachable steel body bracket, including a support rod and a positioning ball, and further, including a bracket base 09. The support rod and the bracket base 09 are both made of steel, and the four corner sides of the bracket base 09 are 32 mm in length; one end of the support rod can be detachably mounted on the bracket base 09, and the other end can be detachably mounted with a positioning ball. There are four groups of support rods and their positioning balls, including a first bracket 05, a second bracket 06, a third bracket 07, a fourth bracket 08, a first positioning ball 01, a second positioning ball 02, a third positioning ball 03 and a fourth positioning ball 04; a spatial tetrahedron is formed with the four positioning balls as endpoints.

[0026] The four corners of the bracket base 09 of this embodiment are respectively provided with base internal thread holes for installing support rods, including the first steel body base internal thread 15, the second steel body base internal thread 16, the third steel body base internal thread 17 and the fourth steel body base internal thread 18. The four base internal thread holes and their support rods are all facing one side; in order to provide a variety of forms, this product has several bracket bases 09, and the directions of the base internal thread holes on each bracket base 09 are different, and the angles of each positioning ball can be selected; at the same time, there can be more than four support rods, and the lengths of each support rod are different. The length of the support rod is 40mm-110mm, and the distances between different positioning balls can be selected.

[0027] In this embodiment, the bracket base 09 is provided with an external through-hole thread 19 in the middle for connecting to external devices such as a screen and a trigger.

[0028] The support rods of this embodiment are provided with support rod external threads including a first support rod external thread 11 , a second support rod external thread 12 , a third support rod external thread 13 and a fourth support rod external thread 14 , and the matching positioning balls are provided with positioning ball internal threads 10 .

[0029] How this product works:

[0030] During installation, the external thread of the support rod at the top is structurally connected with the internal thread 10 of the four positioning balls. Similarly, the external thread at the bottom of the support rod is structurally connected with the internal thread holes of each base to achieve complete assembly of the steel body bracket.

[0031] like Figure 3 As shown, eight different possibilities can be generated by adjusting the position of the threaded hole in the base. The eight positioning balls form a tetrahedron shape with the endpoints to meet the needs of different virtual shooting.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
