Description

Technical Field

[0001] The utility model relates to the technical field of projectors, in particular to a projector for sculpture production. Background Art

[0002] The projector for sculpture production is a professional equipment designed to meet the needs of accurate projection and magnified images in the sculpture production process. It plays an important role in the sculpture production process, especially in realizing complex design and accurate projection. When used, it can accurately project the designed pattern, image or three-dimensional model onto the sculpture material, helping the sculptor to quickly and accurately complete the preliminary modeling of the sculpture. At the same time, the projector can also be used in mold design and architectural design to achieve rapid image magnification and projection and improve work efficiency.

[0003] When using existing sculpture production projectors, it is not convenient to adjust the projection height conveniently, because different sculptures have different heights, so the projected images have different sizes, which requires the projector to be placed at different heights. After the projector height is adjusted, in order to ensure the accuracy of subsequent carving work, it is necessary to ensure that the projector has good stability. The higher the projector is placed, the worse its stability is, and corresponding treatment measures are required. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1-Figure 3 As shown, the embodiment of the utility model provides a projector for sculpture production, comprising:

[0022] A base 1 and a projector body 2, a height adjustment component, the height adjustment component includes a shell 3 fixedly connected to the upper surface of the base 1, a stabilizing threaded rod 4 is rotatably connected to the inner bottom surface of the shell 3 through a bearing, an adjusting threaded rod 5 is fixedly connected to the top of the stabilizing threaded rod 4, a No. 1 nut 6 is threadedly connected to the adjusting threaded rod 5, a limiting slide groove 7 is provided on the side wall of the shell 3, a limiting rod 8 is slidably connected in the limiting slide groove 7, a side end of the limiting rod 8 is fixedly connected to the side wall of the No. 1 nut 6, a side end of the limiting rod 8 is fixedly connected to a bearing plate 9, the projector body 2 is fixedly connected to the side wall of the bearing plate 9, the adjusting threaded rod 5 is rotatably connected to the upper surface of the shell 3 through a bearing, a knob is fixedly connected to the top of the adjusting threaded rod 5, which is convenient for users to adjust, and the side walls of the limiting rod 8 are all in contact with the inner side walls of the limiting slide groove 7 to ensure the stability of the height adjustment component when in use;

[0023] A stabilizing component includes a plurality of cross grooves 10 equidistantly arranged on the upper surface of the base 1, a cross support rod 11 is slidably connected in each of the plurality of cross grooves 10, a plurality of through grooves 12 are equidistantly arranged on the side wall of the shell 3, a No. 2 nut 13 is threadedly connected to the stabilizing threaded rod 4, a plurality of connecting rods 14 are hinged equidistantly on the side wall of the No. 2 nut 13, the bottom ends of the plurality of connecting rods 14 are respectively hinged to the upper surfaces of the plurality of cross support rods 11, the bottom surfaces of the plurality of cross support rods 11 are all in the same plane as the bottom surface of the base 1, the plurality of connecting rods 14 are respectively located in the plurality of through grooves 12, the thread directions of the stabilizing threaded rod 4 and the adjusting threaded rod 5 are opposite, and the pitch of the adjusting threaded rod 5 is three times the pitch of the stabilizing threaded rod 4, so that the height adjustment component and the stabilizing component can cooperate with each other.

[0024] The detailed working process of the utility model is as follows:

[0025] When the height of the projector body 2 needs to be adjusted during use, the adjusting threaded rod 5 is rotated by the knob. When the adjusting threaded rod 5 is rotated, the No. 1 nut 6 is threadedly engaged with the adjusting threaded rod 5 under the restriction of the limiting slide groove 7 and the limiting rod 8, and then moves up and down along the adjusting threaded rod 5, thereby driving the projector body 2 to move up and down through the limiting rod 8 and the bearing plate 9, so as to achieve the corresponding adjustment of the height of the projector body 2, thereby improving the convenience and practicality of the projector when in use;

[0026] When the height of the projector body 2 is adjusted, when the adjusting threaded rod 5 rotates, the stabilizing threaded rod 4 is driven to rotate, and then under the restriction of multiple connecting rods 14, the No. 2 nut 13 will be threadedly engaged with the stabilizing threaded rod 4, so that it will move up and down along the stabilizing threaded rod 4. The thread direction of the stabilizing threaded rod 4 is opposite to the thread direction of the adjusting threaded rod 5. Therefore, the No. 1 nut 6 and the No. 2 nut 13 will move towards each other. When the height of the projector body 2 becomes higher, the No. 2 nut 13 moves downward, so that the multiple connecting rods 14 swing, and then the multiple cross support rods 11 slide out from the multiple cross slide grooves 10 respectively. The higher the height of the projector body 2, the longer the length of the multiple cross support rods 11 sliding out, thereby increasing the ground contact area of ​​the equipment and improving the stability of the equipment. In addition, while gradually increasing the stability according to the adjusted height of the projector body 2, it can also save floor space. Only when the projector body 2 is raised, the stabilizing component will operate, which improves the practicality of the equipment and ensures the subsequent engraving accuracy.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
