Description

Technical Field

[0001] This utility model belongs to the field of LED aging technology, and in particular relates to an aging fixing bracket for LED display modules. Background Technology

[0002] Existing LED indoor and outdoor conventional display module products all have aging grooves on the upper and lower sides of the bottom shell, and the aging fixing bracket is a unified whole. The lower side of the bracket has protrusions to support the aging grooves of the bottom shell, and the upper side of the bracket has clips and springs to fix the upper side of the bottom shell, etc., to ensure that the module will not fall off after it is fixed.

[0003] With the development of LED displays, various unconventional products have emerged (standard external dimensions 320*160mm, unconventional dimensions 80*160, 250*250, 150*330mm, etc.). Different process routes also result in various scenarios, such as simple lamp board aging without locking the bottom shell: ① no aging grooves on the side of the bottom shell, ② bottom shell with two beveled sides, ③ bottom shell with four beveled sides, ④ bottom shell with unconventional dimensions, ⑤ only lamp board aging, etc. Unconventional products cannot be fixed for module aging using conventional aging brackets. To improve this deficiency, this application aims to develop a tilted, fixed aging bracket to accommodate the aging of all the above-mentioned modules. Utility Model Content

[0004] This invention provides an aging support for LED display modules, which can effectively solve the above-mentioned problems.

[0005] This utility model is implemented as follows:

[0006] An aging fixture for an LED display module includes a base frame, a mounting frame, a support frame, and an aging rack. The base frame is a rectangular frame, and the lower ends of the mounting frame and the support frame are respectively connected to the front and rear sides of the base frame. The support frame has several horizontal and vertical bars that are vertically intersecting, and the lower ends of the vertical bars are fixedly connected to the base frame. The mounting frame has several inclined bars, the lower ends of which are connected to the base frame and the upper ends of which are connected to the support frame. The inclined surfaces of the inclined bars are provided with screw holes at intervals. The aging rack has a back plate, side plates, a mounting plate, and a bottom plate. The side plates are vertically arranged on both sides of the back plate, and the mounting plates are vertically arranged on the outer sides of the side plates. The mounting plates are provided with mounting holes, and the bottom plate is located on the lower side of the back plate. The aging rack is fixed to the screw holes of the inclined bars by bolts and screw holes through the mounting holes of the mounting plates.

[0007] As a further improvement, the back plate is a perforated plate, and the upper side of the perforated plate is provided with a comb-shaped backing plate.

[0008] As a further improvement, the side plate is a right-angled triangle, the back plate is connected to the hypotenuse of the right-angled triangle, and the mounting plate is connected to one right-angled side of the right-angled triangle.

[0009] As a further improvement, the upper end of the back plate is provided with a rearwardly bent support plate, and the support plate is provided with a second mounting hole, which is connected to the screw hole on the corresponding inclined rod by a bolt.

[0010] As a further improvement, the mounting hole is a strip-shaped hole.

[0011] As a further improvement, the back plate is provided with clearance grooves corresponding to the mounting holes.

[0012] As a further improvement, the lower end of the tilting rod is hinged to the base frame, the upper end of the tilting rod is provided with a first sleeve rod, the upper end of the vertical rod of the support frame is provided with a second sleeve rod, the upper end of the second sleeve rod is fixedly connected to the horizontal rod, the first sleeve rod is hinged to the second sleeve rod or the horizontal rod, the first sleeve rod and the second sleeve rod are respectively sleeved to the tilting rod and the vertical rod, the first sleeve rod and the second sleeve rod are respectively provided with locking holes at intervals, and the tilting rod and the vertical rod are respectively provided with limiting holes on the sides corresponding to the locking holes.

[0013] As a further improvement, the backplate has a tilt angle of 60°-75°.

[0014] As a further improvement, the front side of the aging rack is provided with an insulating, elastic, or heat-resistant tape layer.

[0015] As a further improvement, the lower end of the base frame is equipped with casters.

[0016] The beneficial effects of this utility model are as follows: This aging support frame, employing an inclined design for both the mounting frame and the aging frame, allows the module to be aged simply by resting its back and sides against the back and bottom plates of the aging frame. It eliminates the need for an aging groove in the bottom shell and the spring clips and protrusions of conventional frames to hold the aging groove in the bottom shell in place; the module's stability is ensured by its own weight. It can achieve aging of both standard and various non-standard modules. When interference occurs between the module and the aging frame, the distance between the upper and lower aging frames can be adjusted, and the modules can be secured with locking bolts. Alternatively, one aging frame can be directly removed to avoid interference, enabling aging of different sizes. Furthermore, the mounting frame angle can be adjusted to change the module's angle, allowing for observation of module illumination and ink color consistency during aging. This product has a simple structure, is easy to operate, has low production costs, and a wide range of applications, which is conducive to its widespread adoption. Attached Figure Description

[0029] Reference Figure 1-6 As shown, an aging support frame for an LED display module includes a base frame 1, a mounting frame 2, a support frame 3, and an aging frame 4. The base frame 1 is a rectangular frame, and the lower ends of the mounting frame 2 and the support frame 3 are respectively connected to the front and rear sides of the base frame 1. The support frame 3 is provided with a plurality of horizontal bars 31 and vertical bars 32 vertically intersectingly connected, and the lower ends of the vertical bars 32 are fixedly connected to the base frame 1. The mounting frame 2 is provided with a plurality of inclined bars 21, the lower ends of which are connected to the base frame 1 and the upper ends of which are connected to the support frame 3. The inclined surface of the inclined rod 21 is provided with screw holes 22 at intervals; the aging rack 4 is provided with a back plate 41, side plates 42, mounting plate 43 and bottom plate 44. The side plates 42 are vertically arranged on both sides of the back plate 41, and the mounting plate 43 is vertically arranged on the outer side of the side plates 42. The mounting plate 43 is provided with mounting holes 431. The bottom plate 44 is located on the lower side of the back plate 41. The aging rack 4 is connected and fixed to the screw holes 22 of the inclined rod 21 by bolts (not shown) through the mounting holes 431 of the mounting plate 43.

[0030] This application adopts a double-tilted structure design of tilting rod 21 and tilting back plate 41. On the one hand, it reduces the tilting angle of tilting rod 21, increases the number of aging racks 4 installed and reduces the width of base frame 1; on the other hand, it ensures that the module 5 maintains a certain tilting angle after placement, and can be stably placed on aging rack 4 without other structural assistance.

[0031] The aging rack 4 can adjust the installation spacing between each layer according to the size of the module 5.

[0032] Furthermore, the back plate 41 is a perforated plate, and the upper side of the perforated plate is provided with a comb-shaped back plate 411.

[0033] The perforated plate reduces material costs, and the comb-shaped back plate 411 supports the module 5, which can reduce the shading area of ​​the module 5 and facilitate heat dissipation.

[0034] Furthermore, the side plate 42 is a right-angled triangle, the back plate 41 is connected to the hypotenuse of the right-angled triangle, and the mounting plate 43 is connected to one right-angled side of the right-angled triangle.

[0035] This structural design ensures that the back panel 41 has a certain tilt angle, which facilitates installation and ensures structural stability.

[0036] Furthermore, the upper end of the back plate 41 is provided with a rearwardly bent support plate 45, and the support plate 45 is provided with a second mounting hole 451. The second mounting hole 451 is connected to the screw hole 22 on the corresponding inclined rod 21 by bolts.

[0037] When the aging rack 4 is long, an inclined rod 21 needs to be added to the back of the aging rack 4 to support it and ensure the support force on the module 5. The rod is fixed to the inclined rod 21 by bolts through the second mounting hole 451.

[0038] Furthermore, the mounting hole 431 is a strip-shaped hole, and the back plate 41 is provided with a clearance groove 412 corresponding to the mounting hole 431.

[0039] The slotted holes facilitate adjustment of the spacing between adjacent aging racks 4.

[0040] Furthermore, the lower end of the inclined rod 21 is hinged to the base frame 1, and the upper end of the inclined rod 21 is provided with a first sleeve rod 211. The upper end of the vertical rod 32 of the support frame 3 is provided with a second sleeve rod 321. The upper end of the second sleeve rod 321 is fixedly connected to the horizontal rod 31. The first sleeve rod 211 and the second sleeve rod 321 are respectively sleeved with the inclined rod 21 and the vertical rod 32. The first sleeve rod 211 and the second sleeve rod 321 are respectively provided with locking holes 212 at intervals. The inclined rod 21 and the vertical rod 32 are respectively provided with limiting holes 213 on the side corresponding to the locking holes 212. The first sleeve rod 211 is movably connected to the second sleeve rod 321 or the horizontal rod 31. The movable connection is that the first sleeve rod 211 and the second sleeve rod 321 or the horizontal rod 31 are fixedly connected to each other with locking screws 214, or the movable connection is that the first sleeve rod 211 and the second sleeve rod 321 or the horizontal rod 31 are provided with a hinge (not shown).

[0041] By adjusting the lengths of the first set of rods 211 and the second set of rods 321 inserted into the tilt rod 21 and the vertical rod 32, the tilt angle of the tilt rod 21 can be adjusted, thereby achieving the adjustment of the angle of the aging frame 4 fixed on the tilt rod 21.

[0042] Furthermore, the tilt angle of the back plate 41 is 60°-75°.

[0043] During aging, it is necessary to observe the lighting status of module 5 and the consistency of ink color, etc. Depending on the product model and the dot pitch of the display screen, the appropriate observation angle is different, so the angle of the aging rack 4 needs to be adjusted.

[0044] Furthermore, the front side of the aging rack 4 is provided with an insulating, elastic, or heat-resistant tape layer.

[0045] Apply insulating, flexible, or heat-resistant tape to prevent short circuits between the ICs on the back of the PCBA and the frame when the LED board ages. This also acts as a shock absorber and prevents heat conduction from the module 5 onto the frame during aging. The insulating, flexible, or heat-resistant tape layer can possess one or more of these functions.

[0046] Furthermore, the lower end of the base frame 1 is provided with casters 11.

[0047] Easy-to-move aging support frame.

[0048] The design features of the LED display module aging support bracket in this application are as follows:

[0049] ① Make an inclined aging rack 4 with an inclination of 60-75° to ensure that the module 5 will not fall after it is placed on it;

[0050] ② The bottom of the base frame 1 is equipped with wheels, which can be rotated to adjust the position of the frame for easy use;

[0051] ③ The metal surfaces of the side and back of the aging rack 4 and the fixed module 5 are covered with insulating, elastic or heat-resistant tape to prevent short circuits between the IC on the back of the PCBA and the rack when only the lamp board is aging. Anti-collision parts are also provided to prevent the high temperature of the module 5 during aging from conducting heat to the rack.

[0052] ④ When aging module 5, simply place the back and sides of module 5 against the surface of aging rack 4. There is no need for an aging groove in the bottom shell, nor is there a need for the spring clips and protrusions of a conventional rack to hold the aging groove in the bottom shell. Of course, conventional module 5 can also be aged.

[0053] ⑤ It can age the above 5 types of modules 5 and the normal module 5. When module 5 interferes, adjust the vertical distance of the aging rack 4 and fix it with the locking screws.

[0054] ⑥ When module 5 is large, one aging rack 4 can be removed directly to avoid interference;

[0055] ⑦ The front-tilted mounting bracket 2 has a mechanism for adjusting the angle by rotation, and works in conjunction with the telescopic column for screw-on fixation.

[0056] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
