Description

Technical Field

[0001] This utility model relates to the field of illuminated sign accessories technology, specifically an assembler for the back panel of an illuminated sign. Background Technology

[0002] Illuminated letters are a type of advertising signage that uses LED lights as the light source. Common types include: exposed illuminated letters: made by punching holes in the surface of sheet metal, stainless steel, aluminum, etc., and installing individual waterproof LED light strings.

[0003] Resin illuminated letters: Composed of two parts, the letter shell and the light source. The outer shell is made of liquid polymer resin material and cast in one piece, or with metal edging and resin surface. The light source is an ultra-high brightness semiconductor light-emitting diode (LED). Various varieties such as fully illuminated letters, ordinary illuminated letters, and flat multi-color illuminated letters can be produced.

[0004] Acrylic illuminated letters: consist of three parts: an acrylic panel, an illuminated letter box, and an illuminated letter light source. The letter panel is shaped by a CNC engraving machine based on a computer-input graphic on an acrylic sheet.

[0005] Vacuum-formed illuminated letters: They consist of three parts: an acrylic vacuum-formed panel, an illuminated letter box, and an illuminated letter light source. The letter panel is made by vacuum forming an acrylic sheet with a raised and recessed surface at high temperature.

[0006] Backlit illuminated letters: Based on metal letters, an luminous module is installed inside the metal shell of the sign to illuminate the background wall. The back of the shell can be sealed with transparent acrylic or supported by screw columns to the wall, so as to achieve the effect of complementing the background wall.

[0007] When assembling acrylic illuminated signs, the acrylic panel is installed inside the illuminated sign box from the rear end. The front end of the illuminated sign box has a folded edge that limits the acrylic panel. Then, the acrylic panel and the inner edge of the illuminated sign box are glued together. Next, the back panel of the illuminated sign light source is installed inside the rear end of the illuminated sign box. In this process, a metal fastener similar to a tilted "S" is usually used to hang on the rear edge of the illuminated sign box. Then, the back panel of the illuminated sign light source is pressed into the inner side of the illuminated sign box. The metal fastener can support the back panel of the illuminated sign light source. Finally, screws or adhesive are used to reinforce and fix the back panel of the illuminated sign light source to the illuminated sign box.

[0008] With this installation method, the metal fasteners protrude from the outside of the illuminated sign box (and when using screws for fixing, the screws also protrude from the outside of the illuminated sign box), which affects the appearance of the illuminated sign box. To avoid this situation, an illuminated sign back panel assembly clip is provided. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-5In this embodiment of the utility model, a back panel assembly clip for a light-up letter includes an assembly clip 2 installed on the rear edge of the housing 102. The assembly clip 2 includes a limiting unit and an unfastening unit.

[0033] The limiting unit is used to provide limiting support for the installation of the light source backplate 103 inside the housing 102;

[0034] The release unit is used to release the support of the limiting unit on the light source back plate 103, thereby realizing the overall removal operation of the assembly clip 2;

[0035] The limiting unit includes a vertical plate 201, a rotating groove 202, a vertical groove 203, a limiting slide groove 204, a support plate 206, a pull plate 207, a limiting block 208, and a 7-shaped clamping plate 209;

[0036] The rotating groove 202 is opened at the bottom of the vertical plate 201, the vertical groove 203 is opened at one end of the vertical plate 201 and passes through the upper and lower ends of the vertical plate 201, and the limiting groove 204 is symmetrically opened on both sides of the inner wall of the vertical groove 203.

[0037] The support plate 206 is rotatably connected to the inner side of the rotating groove 202. The limiting blocks 208 are symmetrically fixed to the bottom of both sides of the pull plate 207. The pull plate 207 is distributed inside the rotating groove 202 and is vertically slidably connected to the limiting slide groove 204 through the limiting blocks 208. The bottom of the pull plate 207 is attached to the upper surface of the support plate 206 to limit the vertical distribution state of the support plate 206 and the vertical plate 201.

[0038] The 7-shaped card plate 209 is fixed to the top of the pull plate 207 at the end away from the vertical plate 201. The vertical plate 201 and the pull plate 207 are hung on the edge of the housing 102 by the 7-shaped card plate 209. The support plate 206 is used to provide support for the back plate 103 of the light source.

[0039] The limit release unit includes a 7-shaped pull plate 210 and a connection point 211;

[0040] Connection points 211 are symmetrically fixed on both sides of the 7-shaped buckle plate 210. The 7-shaped buckle plate 210 is fixed to the top of the inner side of the rotating groove 202 through connection points 211, and the bottom of the vertical part of the 7-shaped buckle plate 210 is in contact with the top of the pull plate 207.

[0041] The 7-shaped buckle plate 210 is used to limit the upward movement of the pull plate 207. The connection point 211 is broken by moving the 7-shaped buckle plate 210 to release the upward movement limit of the pull plate 207.

[0042] In this embodiment, the operation steps for installing the illuminated letter component 1 using this assembly card 2 are as follows:

[0043] First, insert the illuminated letter panel 101 into the box 102 through the rear opening of the box 102. Then, fix the contact position between the illuminated letter panel 101 and the box 102 with glue.

[0044] Next, the assembly card 2 is fitted onto the rear edge of the box 102 using the 7-shaped card plate 209. Its support plate 206 is distributed inside the box 102. Then, multiple assembly cards 2 are installed sequentially along the trajectory of the box 102. (It should be noted that the shapes of the illuminated letter panel 101, box 102, and light source back plate 103 are customized according to customer needs. The front end of the light source back plate 103 is equipped with an LED light board. The power connection wire of the LED light board passes through the light source back plate 103. This is the conventional structure of the existing illuminated letter 1, which is not shown in the figure.)

[0045] Next, the light source back plate 103 is installed inside the housing 102. At this time, multiple support plates 206 support the light source back plate 103, so that the light source back plate 103 and the illuminated letter panel 101 maintain a certain height distance. Then, the light source back plate 103 is glued and fixed to the contact position of the housing 102 with glue (it should be noted that the position of the assembly clip 2 should be avoided when applying glue).

[0046] After the glue solidifies, manually turn the type 7 pull plate 210 upwards to flip it up. The connection point 211 will be twisted and broken under force, thus removing the type 7 pull plate 210. In this way, the pull plate 207 loses its limit and can be manually pulled upwards. As the pull plate 207 moves upwards, it releases the limit on the support plate 206. At the same time, the upward movement of the pull plate 207 causes the support plate 206 to be squeezed against the light source back plate 103. Under this squeezing force, the support plate 206 flips downwards. Finally, the support plate 206 and the pull plate 207 are in a vertical state. Then, continue to pull upwards to move the assembly clip 2 upwards and detach it from the box 102.

[0047] The assembly card 2 can be easily removed by the above operation. After the assembly card 2 is removed, glue can be applied to the original installation position of the assembly card 2.

[0048] Please refer to this carefully. Figures 3-5 A through-hole slot 205 is provided at the position where the vertical plate 201 contacts the 7-shaped buckle plate 210, and a buckle slot is provided on the pull plate 207 above the 7-shaped card plate 209.

[0049] In this embodiment: the through-hole slot 205 and the snap-pull groove facilitate the later contact with the pull-out 207 and the upward pull operation.

[0050] Please refer to this carefully. Figures 4-5The limiting groove 204 extends to the bottom of the vertical plate 201, the thickness of the limiting block 208 matches the inner thickness of the limiting groove 204, and the thickness of the pull plate 207 matches the inner thickness of the vertical groove 203.

[0051] Rotary groove 202 has rotating holes formed on both sides of its inner wall for the support plate 206 to rotate and connect.

[0052] In this embodiment, the upper and lower structures facilitate the assembly and connection of the pull plate 207, the support plate 206 and the vertical plate 201. At the same time, the limiting block 208 and the limiting groove 204 cooperate to limit and guide the upward movement of the pull plate 207.

[0053] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
