Description
Technical Field
[0001] This utility model belongs to the technical field of LED outdoor angled display screen processing equipment, and in particular relates to a universal fixture for the bottom shell of an LED outdoor angled display screen. Background Technology
[0002] Existing LED outdoor right-angle display products require a base shell with angled edges to avoid interference when two displays are spliced at right angles. The module base shell is divided into two-sided angled base shells (where the two opposite short sides of the base shell are angled) and four-sided angled base shells (where all four sides of the base shell are angled). During module production, when assembling and fixing, and applying adhesive, a jig is needed to support the angled parts of the base shell to ensure that the module remains flat and does not tilt when the edges are stressed by fixing or applying adhesive. The applicant previously disclosed CN 220050782 U, a jig structure for an angled base shell, including a jig body with a receiving groove for accommodating and fixing the angled base shell. The two opposite sides of the angled base shell are inclined inwards towards the bottom surface. Two inclined structures are provided on the two opposite sides of the receiving groove; these inclined structures abut against the two inclined sides of the angled base shell to provide support. An inclined structure is provided on each of the two opposite sides of the receiving groove. The inclined structure can cooperate to abut against the two inclined sides of the angled bottom shell to provide support. When the screw machine automatically tightens the screws, the inclined sides of the angled bottom shell are supported by the inclined structure when the chuck presses down, preventing tilting and lifting. This ensures the normal tightening of the screw machine, saves the time and cost of manual tightening, improves efficiency, and reduces costs. CN 222292280U discloses a tray fixture suitable for angled bottom shells, including a tray body. The tray body has a plurality of nut enlarged holes penetrating the front and back. Each nut enlarged hole corresponds to a fixing hole located on the back of the angled bottom shell. The fixing hole is a screw hole for tightening the angled bottom shell to the box body. The front of the tray body also has a plurality of clearance holes for the fixing posts on the back of the angled bottom shell. With the back of the angled bottom shell facing the front of the tray body, mechanical screws are passed through the enlarged holes of the nuts on the back of the tray body and locked into the fixing holes of the angled bottom shell. This connects and fixes the angled bottom shell and the tray fixture as a whole, facilitating subsequent modular assembly of accessories such as the angled bottom shell, PCB board, and face mask. It also prevents the angled bottom shell from tilting or warping at one end, effectively improving production efficiency. However, all of these methods require the use of a tray for installation and have at least one of the following disadvantages:
[0003] ① Two-sided beveled bottom shell: The two beveled sides are supported by a splicing bracket, which is then locked and glued. It needs to be removed after use, which is a cumbersome process.
[0004] ② Four-sided beveled bottom shell: A support bracket and tray are used to support the four beveled sides. The positioning holes of the bottom shell and the positioning pins on the tray are inserted and fixed. Locking and potting are then performed. Locking cannot be done using the normal production procedure. The locking position needs to be readjusted, which is time-consuming and affects the wiring. After the potting and drying, the support bracket needs to be removed, which is a cumbersome process. During aging, magnets are installed using the nut holes on the back of the module, and then the square tube is magnetically attached to fix it. After completion, it can be removed (for standard modules or two-sided beveled modules, the slots on the long side of the module bottom shell can be directly used to install it onto the aging rack without magnetic attachment).
[0005] ③ Fixtures with two beveled bottom shells and fixtures with four beveled bottom shells cannot be used interchangeably;
[0006] ④ Angled and right-angled screens require disassembly of the fixture and can only be shipped as angled modules. Utility Model Content
[0007] This utility model provides a universal fixture for the bottom shell of an outdoor LED angled display screen, which can effectively solve the above-mentioned problems.
[0008] This utility model is implemented as follows:
[0009] A universal fixture for the bottom shell of an outdoor LED angled display screen includes a short side fitting plate. The short side fitting plate has a bottom surface, a right-angle surface, a triangular bevel, and a support column. The bottom surface is perpendicularly connected to the right-angle surface. The triangular bevel connects the bottom surface and the right-angle surface. The triangular bevel abuts against the bevel of the bottom shell. The support column is located on the inner side of the bottom surface of the short side fitting plate and corresponds to the screw hole of the bottom shell.
[0010] A universal fixture for the bottom shell of an outdoor LED angled display screen includes a short side fitting plate, a long side fitting plate, and connecting corner pieces. The short side fitting plate and the long side fitting plate each have a bottom surface, a right-angled surface, a triangular bevel, a support column, and a screw hole column. The bottom surface is perpendicularly connected to the right-angled surface, and the triangular bevel connects the bottom surface and the right-angled surface. The triangular bevel abuts against the angle of the bottom shell. The support column is located inside the bottom surface of the short side fitting plate and corresponds to the screw holes of the bottom shell. The long side fitting plate has connecting bevels at both ends that abut against the triangular bevels of the short side fitting plate. Screw holes are located at both ends of the short side fitting plate and the long side fitting plate. The short side fitting plates and the long side fitting plate are joined together in pairs to form a rectangular fixture. The connecting corner pieces are locked to the screw holes of adjacent short side fitting plates and long side fitting plates by screws.
[0011] As a further improvement, at least one of the support columns is provided with a screw hole for fixing to the bottom shell.
[0012] As a further improvement, triangular reinforcing blocks are provided on the inner sides of the bottom surface and the right-angled surface.
[0013] As a further improvement, a groove is provided on the outer side of the right-angled surface along the length direction.

[0017] As a further improvement, the support columns at both ends of the short side patch plate and the long side patch plate are provided with screw holes.
[0018] As a further improvement, the short-side and long-side reinforcement plates are each provided with grooves. During product aging, the product can be directly installed onto the aging rack using the grooves of the long-side reinforcement plates without magnetic attraction. Alternatively, an aging fixture can be used for aging fixation. The aging fixture is provided with a "U"-shaped frame and magnetic supports. The "U"-shaped frame is inserted into the grooves of the short-side and long-side reinforcement plates, and the magnetic supports are located at both ends of the "U"-shaped frame.
[0019] The beneficial effects of this utility model are as follows: the short-side fitting plate of the fixture can be used alone to fit two opposite short sides of a bottom shell that are angled; or it can be used in conjunction with the long-side fitting plate to form a rectangular fixture by connecting corner pieces, used to fit four sides of a bottom shell that are angled. The fixture of this application does not require a tray, and no manual magnetic fixation is needed during aging; the processing can use the existing standard assembly program without needing to readjust the locking positions, ensuring normal operation of the production line; the screw holes on the bottom surface allow for screw fixation, and it can also be used as a standard assembly for shipment. This fixture has a simple structure, is easy to assemble, and can be directly used for aging and shipping, simplifying the production and assembly process of angled bottom shells, improving production efficiency, reducing production costs, and facilitating the promotion and application of the product.
