Description

Technical Field

[0001] The present application relates to the field of mechanical design and engineering technology, and in particular to a projector rotating bracket. Background Art

[0002] With the continuous development of science and technology, projection technology has become an indispensable part of modern life. As a common display device, projectors are widely used in education, business presentations, entertainment and other fields. In order to improve the flexibility and applicability of projectors, projector swivel brackets, as one of its important accessories, are constantly undergoing technological innovation and design optimization.

[0003] Traditional projector stands need to be fixed in a preset position to determine the horizontal orientation of the projector. The projection height of the projector can only be adjusted by adjusting the vertical angle between the projector and the setting plane. Therefore, traditional projectors can often only achieve fixed-direction projection. In some specific scenarios, users may need to adjust the direction of the projector to adapt to different display needs.

[0004] Therefore, based on the above problems, the prior art needs to be improved. Utility Model Content

[0005] The purpose of this application is to enable the projector bracket to be flexibly set up and installed, and to be able to adjust the projection direction of the projector in the horizontal and vertical directions, thereby improving the flexibility of the projection direction setting.

[0006] The above technical purpose of the present application is achieved through the following technical solutions: a projector rotating bracket, including a base, a first fixing part is provided on the base, a horizontal rotating bracket is rotatably provided on the first fixing part, a second fixing part is provided on the horizontal rotating bracket, a vertical rotating bracket is rotatably provided on the second fixing part, the axis of the first fixing part is perpendicular to the axis of the second fixing part, and a surface cover is provided on the vertical rotating bracket for installing the projector.

[0007] By adopting the above technical solution, the projector can be conveniently set up through the base, and the installation position of the projector can be flexibly adjusted; the design of the base and the fixing parts can provide sufficient stable support for the projector, ensuring that the projector is stable and reliable when installed on the bracket, avoiding shaking or distortion of the projected image due to unstable bracket. Through the combination of the horizontal rotation bracket and the vertical rotation bracket, the bracket realizes multi-directional adjustment of the projector, including horizontal and vertical rotation, so that the user can flexibly adjust the angle and direction of the projector according to specific needs.

[0008] Optionally, the base includes a bottom cover, a shell is provided on the bottom cover, the shell and the bottom cover together form a accommodating cavity, the bottom cover is provided with a groove, and a counterweight is provided in the groove.

[0009] By adopting the above technical solution, the bottom cover and the shell are combined to form a accommodating cavity. This design can provide a more stable support structure, effectively reduce the shaking and instability of the bracket, and ensure the stability of the projector during use. A counterweight block is provided in the groove, and the position and number of the counterweight block can be flexibly adjusted as needed, so that the bracket can maintain balance while carrying the projector, avoiding tilting and shaking caused by unstable center of gravity. The combined design of the bottom cover and the shell is simple and compact, and occupies less space, making the bracket more suitable for placement in different environments, whether it is a desktop, floor or other platform, it can effectively utilize space.

[0010] Optionally, a mounting groove is recessed on the horizontal rotating bracket, and the horizontal rotating bracket is fitted with the first fixing member through the mounting groove, and the horizontal rotating bracket rotates relative to the base through the first fixing member.

[0011] By adopting the above technical solution, through the design of the mounting groove, the horizontal rotation bracket can be tightly connected with the first fixing member to form a stable structure. This connection method can ensure that the bracket will not loosen or fall off during the rotation process, thereby improving the stability and reliability of the bracket. The horizontal rotation bracket can be assembled with the first fixing member through the mounting groove to achieve rotation relative to the base. This design allows the user to easily adjust the angle of the projector in the horizontal direction to adapt to different projection requirements, thereby improving the flexibility and applicability of the bracket. Since the connection method between the horizontal rotation bracket and the first fixing member is simple and reliable, the user can complete the adjustment of the horizontal angle through simple operation, which is convenient to operate and saves time and effort.

[0012] Optionally, a first locking piece is provided on the inner wall of the installation groove, and a plurality of second locking pieces are provided on the first fixing piece along the setting direction of the inner wall of the installation groove, and the first locking piece and the second locking piece are engaged with each other.

[0013] By adopting the above technical solution, the first and second clamping members are provided on the inner wall of the mounting groove, so as to realize the clamping connection between the horizontal rotating bracket and the first fixing member. This clamping design can produce a damping effect. When the user adjusts the angle of the horizontal rotating bracket, the matching clamping between the first and second clamping members will provide an appropriate amount of resistance, making the adjustment more stable and accurate, and avoiding excessive rotation or sudden stop due to inertia. The damping effect can not only smoothly adjust the horizontal angle, but also enhance the stability of the bracket. During the projection process of the projector, the bracket may shake due to ground vibration or other external factors. The damping effect can slow down the shaking speed, making the projected image more stable and improving the viewing experience. The damping effect can reduce the vibration and impact of the bracket, reduce the pressure on the internal parts of the bracket, and reduce the degree of wear of the parts, thereby extending the service life of the bracket, reducing the frequency of maintenance and replacement, and saving maintenance costs.

[0014] Optionally, the shell is provided with a plug hole, and the first fixing member is provided with a latch, and the latch can pass through the plug hole.

[0015] By adopting the above technical solution, a socket is provided on the housing, and a latch is provided on the first fixing member, and the latch can pass through the socket. Through the combination of the latch and the socket, the first fixing member and the base are firmly fixed and accurately positioned. This design can ensure that the bracket will not loosen or fall off during use, thereby improving the stability and reliability of the bracket. The design of the latch and the socket is simple and reliable, and the user can complete the assembly and disassembly of the bracket through simple operations without the need for additional tools or complicated steps. The operation is simple, saving time and effort.

[0016] Optionally, the latch is provided with a slot for the fastener to pass through.

[0017] By adopting the above technical solution, a slot is provided on the latch to ensure accurate positioning of fasteners such as bolts. The fastener can pass through the shell and the first fixing member through the slot to complete the installation of the first fixing member and the base, thereby improving the stability and reliability of the bracket.

[0019] By adopting the above technical solution, the second fixing member is hollowly arranged to form an installation channel, the rotating member passes through the channel, and the installation member rotates relative to the second fixing member through the rotating member. This design allows the installation member of the rotating bracket to move in the channel without protruding from the outside of the bracket, thereby maintaining the overall compactness of the bracket and not increasing the additional occupied space. The installation channel allows the installation member to move therein. The user only needs to insert the installation member into the channel and then fix it in the desired position through the rotating member. The installation process is simple and convenient. This design reduces the need for installation steps and tools, and reduces the difficulty of operation for the user. The installation member rotates relative to the second fixing member through the rotating member, and the user can change the installation angle of the projector by adjusting the position of the installation member in the channel. This design makes it more flexible to adjust the direction and angle of the projector, which can adapt to different projection needs and environments.

[0020] Optionally, a third locking member is provided on the rotating member, and a plurality of fourth locking members are provided at the channel opening of the installation channel along the axis of the installation channel, and the third locking member and the fourth locking member are engaged with each other.

[0021] By adopting the above technical solution, the third and fourth clamping parts are provided on the inner wall of the mounting groove, so as to realize the clamping between the vertical rotating bracket and the second fixing part. This clamping design can produce a damping effect. When the user adjusts the angle of the horizontal rotating bracket, the matching clamping between the third and fourth clamping parts will provide an appropriate amount of resistance, making the adjustment more stable and accurate, and avoiding excessive rotation or sudden stop due to inertia. The damping effect can not only smoothly adjust the horizontal angle, but also enhance the stability of the bracket. During the projection process of the projector, the bracket may shake due to ground vibration or other external factors. The damping effect can slow down the shaking speed, making the projected image more stable and improving the viewing experience. The damping effect can reduce the vibration and impact of the bracket, reduce the pressure on the internal parts of the bracket, and reduce the wear of the parts, thereby extending the service life of the bracket, reducing the frequency of maintenance and replacement, and saving maintenance costs.

[0022] In summary, this application has at least the following beneficial effects:

[0024] 2. The design of the first and second clamping parts on the inner wall of the installation groove realizes the clamping connection between the horizontal rotation bracket and the first fixing part, and this clamping design can produce a damping effect. When the user adjusts the angle of the horizontal rotation bracket, the matching clamping between the first and second clamping parts will provide an appropriate amount of resistance, making the adjustment more stable and precise, and avoiding excessive rotation or sudden stop due to inertia.
