Description

Technical fields:

[0002] This utility model relates to a connection plate structure that facilitates the installation of a projector power adapter. Background technology:

[0004] As an important component of modern display devices, projectors are widely used in home theaters, business meetings, education, and engineering. To facilitate installation and adjustment, projectors are typically mounted on cantilever beams, as in patent number 201110211520.3, invention title: Projector Positioning Device. This device allows for adjustment of the projector's three coordinates. However, since projectors require connection to components such as power adapters, the power adapters are currently often haphazardly placed beside the projector. This can lead to unstable connections between the power adapter and the projector's power socket, resulting in power outages. Furthermore, haphazardly placed projectors can negatively impact aesthetics and occupy space below the projector. Summary of the Invention:

[0006] In view of the problems existing in the prior art, the purpose of this utility model is to propose a connection plate structure that facilitates the installation of projector power adapters. This connection plate structure facilitates the reasonable installation and placement of power adapters and ensures the stability of power connection.

[0007] This utility model is implemented using the following solution.

[0008] This utility model relates to a connecting plate structure for facilitating the installation of a projector power adapter. The structure is characterized by comprising a connecting plate with a lower surface for mounting the projector housing and an upper surface for mounting the free end of a cantilever beam. The upper surface of the connecting plate has an extension portion, and the upper surface of the extension portion is provided with a first limiting plate and a second limiting plate arranged parallel to each other. The first limiting plate is provided with a spring sheet arching towards the second limiting plate, and the power adapter of the projector is mounted between the spring sheet and the second limiting plate.

[0009] Preferably, the aforementioned extension and the first limiting plate and the second limiting plate on the extension plate are integral sheet metal parts with the connecting plate.

[0010] Preferably, the spring sheet is an elastic metal sheet with lugs on both sides. The two lugs are positioned in two through holes on the first limiting plate. The distance between the through holes is less than the distance between the two lugs, so that the spring sheet arches towards the second limiting plate. The arching of the spring sheet and the second limiting plate limit the width direction of the power adapter.

[0011] Preferably, the upper edge of the second limiting plate is provided with a curved portion toward the first limiting plate, and the lower surface of the curved portion and the upper surface of the extension portion limit the thickness direction of the power adapter.

[0012] Preferably, the protruding end of the extension is provided with an upper protrusion to restrict the movement of the power adapter in the length direction, and the position of the extension relative to the upper protrusion is open.

[0013] Preferably, the front and rear sides of the connecting plate are respectively provided with a front piece and a rear piece, and the front piece and the rear piece are provided with a strip groove, and a screw is inserted into the strip groove to be threadedly connected to the screw hole on the free end of the cantilever beam.

[0014] Preferably, the connecting plate has through holes, and screws pass through the through holes to make threaded connections with the threaded holes on the projector housing.

[0015] This utility model features a connecting plate structure that facilitates the installation of a projector power adapter. It uses a first limiting plate and a second limiting plate that are arranged in parallel and spaced apart. The first limiting plate has a spring sheet that arches towards the second limiting plate, which allows the projector power adapter to be limited between the spring sheet and the second limiting plate. This serves to limit the installation of the projector power adapter and avoids the drawbacks caused by the projector power adapter being arbitrarily hung vertically. Attached image description:

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] This utility model relates to a connecting plate structure for easy installation of a projector power adapter. The connecting plate 3 has a lower surface for mounting the projector housing 1 and an upper surface for mounting the free end of the cantilever beam 2. The upper surface of the connecting plate 3 has an extension 4. The upper surface of the extension 4 is provided with a first limiting plate 5 and a second limiting plate 6 arranged in parallel at intervals. The extension 4 and the first limiting plate 5 and the second limiting plate 6 on the extension plate are integral sheet metal parts with the connecting plate 3. Of course, other machined parts can also be used, but using an integral sheet metal part results in lower processing costs and higher structural stability.

[0024] The first limiting plate 5 is provided with a spring sheet 7 that arches towards the second limiting plate 6. The power adapter 8 of the projector is installed between the spring sheet 7 and the second limiting plate 6. Specifically, the spring sheet is an elastic metal sheet with a rectangular main body and two lugs 71. The spring sheet can bend when subjected to force and return to its original state after the external force is removed. Its material can be spring steel, stainless steel, etc. The two lugs are limited in two through holes 51 on the first limiting plate 5. The distance between the through holes is less than the distance between the two lugs, so that the spring sheet arches towards the second limiting plate. The arching of the spring sheet and the second limiting plate limit the width direction of the power adapter. The distance between the arched end of the spring sheet and the second limiting plate is slightly less than the width of the power adapter, so that the spring sheet has a certain pressure in the direction of the second limiting plate, ensuring the stability of the power adapter installed between the first limiting plate 5 and the second limiting plate 6.

[0025] To ensure a more stable and reliable installation, the upper edge of the second limiting plate 6 is provided with a curved portion 61 facing the first limiting plate. The lower surface of the curved portion 61 and the upper surface of the extension limit the thickness direction of the power adapter. The end of the extension 4 is provided with an upper protrusion 41 to restrict the movement of the power adapter in the length direction. The position of the extension relative to the upper protrusion is open. When installing the power adapter, the power adapter can be pushed from the open position towards the upper protrusion 41. After being pushed into place, the power adapter is installed and fixed. Since the width direction of the power adapter is limited by the spring plate 7 and the second limiting plate 6, and the thickness direction of the power adapter is limited by the lower surface of the curved portion 61 and the upper surface of the extension, the power adapter is installed stably and reliably on the connecting plate 3, and is easy and quick to install and remove.

[0026] The front and rear sides of the connecting plate 3 are respectively provided with a front piece 31 and a rear piece 32. Both the front piece and the rear piece are provided with a strip groove 33. By inserting screws into the strip grooves to connect with the screw holes 21 on the free end of the cantilever beam 2, the connecting plate 3 and the cantilever beam 2 are fixed.

[0027] The connecting plate 3 has a through hole 34, and a screw is passed through the through hole 34 to make a threaded connection with the threaded hole on the projector housing 1.

[0028] This utility model features a connecting plate structure that facilitates the installation of a projector power adapter. It uses a first limiting plate and a second limiting plate that are arranged in parallel and spaced apart. The first limiting plate has a spring sheet that arches towards the second limiting plate, which allows the projector power adapter to be limited between the spring sheet and the second limiting plate. This serves to limit the installation of the projector power adapter and avoids the drawbacks caused by the projector power adapter being arbitrarily hung vertically.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
