Description

Technical Field

[0001] The utility model relates to a skeleton structure of a projector bracket. Background Art

[0002] A projector, also known as a projection machine, is a device that can project images or videos onto a screen and is widely used in homes, offices, schools, and entertainment venues. According to different usage methods, it can be divided into desktop projectors, portable projectors, floor-standing projectors, reflective projectors, transmissive projectors, etc.

[0003] Among them, portable projectors are widely loved because of their small size and convenient portability. Existing portable projectors are usually supported by a bracket and placed on a tabletop or other surfaces for use. The projector and the bracket can be rotated to adjust the up and down projection angles of the lens, but the bracket itself cannot be rotated left and right. When adjusting the left and right directions, the bracket needs to be manually moved, and the angle adjustment in the left and right directions is inconvenient. For example, CN202321819752.1, a projector with a high-stability bracket structure, or CN202320349889.9, a projector. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a skeleton structure of a projector bracket, which is convenient to connect with a projector device and convenient for the projector device installed thereon to rotate left and right.

[0005] The technical solution of the utility model lies in: a skeleton structure of a projector bracket, including a support bottom plate, a rotating seat plate is rotatably connected to the support bottom plate, vertical support arm plates are respectively fixed to both sides of the rotating seat plate, and mounting shaft holes for connecting with the side part of the projector are horizontally arranged at the upper ends of the support arm plates.

[0006] Further, the diameter of the rotating seat plate is larger than the diameter of the support bottom plate, and a plurality of anti-slip pads are arranged at intervals on the bottom surface of the support bottom plate.

[0007] Further, a plurality of fixing columns for connecting with the outer shell are arranged at intervals along the circumferential direction on the upper side surface of the rotating seat plate, and threaded holes are vertically arranged at the upper ends of the fixing columns.

[0008] Further, a first bolt hole is arranged from bottom to top between adjacent two fixing columns on the rotating seat plate, and a circle of second bolt holes is arranged at intervals inside the countersunk bolt hole.

[0009] Further, a connecting plate for connecting with the rotating seat plate is arranged at the lower end of the support arm plate, and a countersunk bolt that is screwed with the connecting plate is vertically penetrated through the rotating seat plate from bottom to top.

[0010] Further, the support arm plate is made of sheet metal and has flanges on both sides, and a plurality of bolt holes are arranged at intervals along the vertical direction on the support arm plate.

[0011] Further, threaded holes are arranged at intervals around the mounting shaft hole at the upper part of the support arm plate on one side, and positioning slot holes are arranged on the upper, lower sides of the mounting shaft hole at the upper part of the support arm plate on the other side.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] 1. The skeleton structure of the projector bracket is simple and compact, which is convenient for installation and connection with the projector device. The rotation connection between the rotation seat plate and the support bottom plate facilitates the left - right rotation of the projector device installed thereon to adjust the projection orientation.

[0014] 2. The support bottom plate, rotation seat plate and support arm plate of the projector bracket skeleton are all metal plate parts, and the support arm plates are symmetrically arranged on both sides of the rotation seat plate, which helps to ensure the overall stability when the projector is placed on the table.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] To make the above - mentioned features and advantages of the utility model more understandable, the following specific embodiments are given in conjunction with the accompanying drawings for detailed description, but the utility model is not limited thereto.

[0020] Reference Figures 1 to 3

[0021] A projector bracket skeleton structure includes a support bottom plate 10. A rotary seat plate 20 is rotatably connected to the support bottom plate. Vertically upward support arm plates 30 are respectively fixed to two sides of the rotary seat plate. Mounting shaft holes 31 for connecting to the side of the projector are horizontally arranged at the upper ends of the support arm plates, so that the projector can rotate between the two support arm plates.

[0022] In this embodiment, a vertical rotating shaft 11 rotatably connected to the support bottom plate is fixed in the middle of the rotary seat plate; a positioning notch 21 is arranged at the front part of the rotary seat plate to prevent installation errors when installing components such as the outer shell.

[0023] In this embodiment, the diameter of the rotary seat plate is larger than that of the support bottom plate to block the support bottom plate and improve aesthetics; four anti-slip pads 12 are arranged at intervals on the bottom surface of the support bottom plate so that the support bottom plate can better support on the desktop.

[0024] In this embodiment, a plurality of fixing columns 22 for connecting to the outer shell are arranged at intervals along the circumferential direction on the upper side surface of the rotary seat plate. Threaded holes are vertically arranged at the upper ends of the fixing columns to better connect with components such as the outer shell.

[0025] In this embodiment, first bolt holes 23 are arranged from bottom to top between adjacent fixing columns on the rotary seat plate, and a circle of second bolt holes 24 are arranged at intervals inside the countersunk bolt holes.

[0026] In this embodiment, in order to better install the support arm plate on the rotary seat plate, a connecting plate 37 connected to the rotary seat plate is arranged at the lower end of the support arm plate, and a countersunk bolt 32 that is screwed to the connecting plate is vertically penetrated through the rotary seat plate from bottom to top.

[0027] In this embodiment, the connecting plate is integrally formed with the support arm plate body through an arc portion. The support arm plate is made of sheet metal and flanging 33 is arranged on the side to improve the strength of the support arm plate. A plurality of bolt holes 34 are arranged at intervals vertically on the support arm plate, and then screws are passed through the bolt holes to connect with the outer shell parts.

[0028] In this embodiment, in order to better install the rotating shaft part connected to the projector device, threaded holes 35 are arranged at intervals around the mounting shaft hole at the upper part of one side of the support arm plate; positioning slot holes 36 are arranged on the upper and lower sides of the mounting shaft hole at the upper part of the support arm plate on the other side to install and position the hollow rotating shaft part and facilitate the passing of wires and the like.
