Description

Technical Field

[0001] This utility model belongs to the technical field of three-dimensional human body scanning equipment, specifically relating to a quick-connect structure at the top of the column in a multi-view three-dimensional human body scanner. Background Technology

[0002] Existing 3D human body scanners consist of multiple columns, a frame, and a top plate. The bottoms of the columns are fixedly connected to the horizontal plane, the frame is set between adjacent columns, and the tops of adjacent columns are connected by the top plate. Cameras are installed on the columns or the top of the frame. Multiple cameras scan the model located between the frames to generate a 3D model. The connection between the top plate and the columns is mostly made with screws or bolts, which require tools to tighten. However, the top plate is located high up, and the tightening process requires climbing a ladder to lock it, which is very cumbersome and requires multiple people to cooperate. In view of this, this solution was developed. Utility Model Content

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a quick-connect structure for the top of the column in a multi-view 3D human body scanner, which can manually tighten the connecting column between the top plate and the column.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a quick-connect structure for the top of a column in a multi-view 3D human body scanner, including a column, a top plate, and a connecting column. The upper surface of the column is provided with a threaded hole, and the top plate is provided with a through hole. The through hole and the threaded hole correspond to each other. The connecting column includes a gripping and rotating part, a transition part, a pressing part, and a threaded part. The gripping and rotating part, the transition part, the pressing part, and the threaded part are arranged sequentially from top to bottom. The diameter of the pressing part is larger than the diameter of the threaded part. The threaded part of the connecting column passes through the through hole and is screwed into the threaded hole. The lower surface of the pressing part presses against the upper surface of the top plate.

[0005] Furthermore, the upper surface of the column is provided with four threaded holes arranged in a matrix, with each pair of threaded holes on the same side connecting to a top plate.

[0006] Furthermore, the column is a hollow column, and the bottom of the column has a wire passage groove that passes through two corresponding side walls of the column.

[0007] Furthermore, the column has an installation chamber and a wire passage chamber, which are respectively connected to the installation chamber and the wire passage groove.

[0008] Furthermore, the wire passage chamber and the installation chamber are separated by a wire guide plate, and the wire is provided with multiple wire holes.

[0009] Furthermore, the inner side of the column has multiple camera mounting holes.

[0010] Furthermore, the camera mounting hole is circular or rectangular.

[0011] Furthermore, the column includes a column body and a rear cover plate. An opening is formed on the back of the column body. Limiting connection plates are formed on the two side walls of the mounting chamber near the opening. The rear cover plate is embedded in the opening and is detachably connected to the limiting connection plates.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention improves the connecting column, which includes a gripping and rotating part, a transition part, a pressing part, and a threaded part. When connecting the top plate and the column, simply align the threaded part with the through hole and the threaded hole, then grip and rotate the part until the lower surface of the pressing part tightly presses against the upper surface of the top plate, thereby achieving fixation. Because there is a transition part between the pressing part and the gripping and rotating part, when the pressing part is tightly attached to the top plate, there is a certain distance between the gripping and rotating part and the top plate, ensuring smooth rotation.

[0023] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0024] like Figure 1 As shown, the 3D human scanner consists of multiple uprights 1, multiple base plates, multiple side plates 2, and multiple top plates 3. The base plates are joined end-to-end to form a polygon. The base plates have a V-shaped structure projected horizontally with an included angle of 330°. Multiple fixed posts are formed on the upper surface of the base plates. The number of fixed posts can be set according to actual conditions; for stable insertion, the number of fixed posts should not be less than two. In this embodiment, the number of fixed posts is four, arranged in a matrix. The fixed posts are located at the center of the included angle on the upper surface of the base plates. The bottom of each upright 1 has multiple insertion holes, which are inserted into the fixed posts on the base plates. The top plate 3 is erected between two adjacent uprights 1, and its two ends are connected to the uprights 1. The top plate 3 has an L-shaped cross-section. The side plates 2 are connected to the outward-facing side of adjacent uprights 1. Multiple side plates 2 are spliced ​​together to form a frame. In this embodiment, the number of uprights 1, base plates, side plates 2, and top plates 3 is 12.

[0025] like Figures 1-8 As shown, this embodiment provides a quick-connect structure at the top of the column 1 in a multi-view 3D human body scanner, comprising the column 1, the top plate 3, and the connecting column 4.

[0026] The upper surface of the column 1 is provided with four threaded holes 17 arranged in a matrix. Every two threaded holes 17 on the same side are connected to a top plate 3. The top plate 3 is provided with two through holes 31 on both sides, and the two through holes 31 correspond to the two threaded holes 17 on the same side. The connecting column 4 includes a holding and rotating part 41, a transition part 42, a pressing part 43 and a threaded part 44. The holding and rotating part 41, the transition part 42, the pressing part 43 and the threaded part 44 are arranged in order from top to bottom. The diameter of the pressing part 43 is larger than the diameter of the threaded part 44. The threaded part 44 of the connecting column 4 passes through the through hole 31 and is screwed into the threaded hole 17. The lower surface of the pressing part 43 presses against the upper surface of the top plate 3.

[0027] This solution improves the connecting column 4, which includes a gripping and rotating part 41, a transition part 42, a pressing part 43, and a threaded part 44. When connecting the top plate 3 and the column 1, it is only necessary to align the threaded part 44 with the through hole 31 and the threaded hole 17, and then grip the rotating part 41 until the lower surface of the pressing part 43 presses tightly against the upper surface of the top plate 3, thereby achieving fixation. Since there is a transition part 42 between the pressing part 43 and the gripping and rotating part 41, when the pressing part 43 is tightly attached to the top plate 3, there is a certain distance between the gripping and rotating part 41 and the top plate 3, ensuring smooth rotation.

[0028] The column 1 is a hollow column 1. The bottom of the column 1 has a cable passage groove 15, which passes through two corresponding side walls of the column 1. Specifically, the column 1 has a mounting chamber 14 and a cable passage chamber 16. The cable passage chamber 16 is connected to the mounting chamber 14 and the cable passage groove 15 respectively. The cable passage chamber 16 and the mounting chamber 14 are separated by a wire guide plate 161. Multiple wire holes 162 are provided on the wire. Three camera mounting holes 13 are formed on the inward side of the column 1. The number of camera mounting holes 13 in adjacent columns 1 is different. One has two camera mounting holes 13, and the other has three camera mounting holes 13. The camera mounting holes 13 are circular or rectangular. The uppermost camera mounting hole 13 in the column 1 with three camera mounting holes 13 is rectangular. The camera is placed in the square-shaped camera mounting hole 13 and can be adjusted up and down.

[0029] The column 1 includes a column body 11 and a rear cover plate 12. An opening is formed on the back of the column body 11. Limiting connecting plates are formed on the two side walls of the mounting chamber 14 near the opening. The rear cover plate 12 is embedded in the opening and is detachably connected to the limiting connecting plates. Specifically, the rear cover plate 12 and the limiting connecting plates are connected by screws, which facilitates camera installation and maintenance.

[0030] Preferably, the upper end of the side plate 2 has an inwardly extending plate with a first through hole, and the top plate 3 has a second through hole corresponding to the first through hole. The plate and the top plate 3 are connected by bolts to ensure the stability of the side plate 2 after installation.

[0031] The foregoing has shown and described the basic principles and main features of this invention, as well as its advantages. Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention. Various changes and modifications can be made to this invention without departing from its spirit and scope. All such changes and modifications fall within the scope of this invention as defined by the appended claims and their equivalents.
