Description

Technical Field

[0001] This utility model belongs to the field of signboard technology, specifically, it relates to a splicing type outdoor LED illuminated signboard. Background Technology

[0002] LED illuminated signs are illuminated signage products made using light-emitting diodes (LEDs) as the light source. With their diverse colors, uniform and bright lighting effects, high energy efficiency, and ease of installation and use, they have become popular and rapidly adopted by advertising clients. LED illuminated signs generally consist of a panel, a housing, and LED light sources. Based on different lighting effects, they can be categorized into several types, including LED exposed light illuminated signs, LED vacuum-formed illuminated signs, LED lightbox illuminated signs, LED backlit signs, and LED resin illuminated signs.

[0003] Although LED illuminated signs have been widely used in the advertising signage field, existing LED illuminated signs have a significant drawback: the characters on the illuminated signs are fixed and cannot be flexibly changed as needed. When faced with scenarios such as updates to advertising content or adjustments to shop signs, these fixed-character illuminated signs often require a complete replacement of the signs, leading to increased costs and low efficiency. Utility Model Content

[0004] In order to solve the problems existing in the prior art, this utility model aims to provide a splicing type outdoor LED illuminated signboard to achieve flexible replacement of characters.

[0005] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0006] An outdoor LED illuminated signboard with interlocking panels includes a housing with a through front and rear end. A character panel is provided at the front end of the housing, and an LED light source panel is provided at the rear end of the housing. A light-transmitting panel is provided inside the housing between the character panel and the LED light source panel. Locking holes are provided on the character panel and the LED light source panel, and a movable pin mechanism is inserted through the locking holes. Locking mechanisms adapted to the pin mechanisms are provided at the upper and lower ends of the housing, respectively. The character panel and the LED light source panel are detachably locked to the housing through the cooperation of the pin mechanisms and the locking mechanisms.

[0007] Furthermore, a hollow cavity is formed at the upper and lower ends of the shell, and the locking mechanism is fixed to the bottom surface of the hollow cavity.

[0008] Furthermore, a cover plate is provided at the opening of each of the hollow chambers.

[0009] Furthermore, both the character board and the LED light source board are embedded within the housing, and neither the front end face of the character board nor the rear end face of the LED light source board protrudes from the housing.

[0010] Furthermore, the locking hole is provided with internal threads.

[0011] Furthermore, the pin mechanism includes a pin, a first spring and a slider that can slide thereon are sleeved on the outer surface of the pin; and a fixing block is connected to the front end of the pin.

[0012] Furthermore, the pin is a stepped shaft, which consists of a first stepped segment, a second stepped segment, a third stepped segment, and a fourth stepped segment with successively decreasing outer diameters, and the outer surface of the fourth stepped segment is provided with external threads.

[0013] Furthermore, the left and right halves of the slider retract inward.

[0014] Furthermore, the outer surface of the fixing block is an arc surface; the fixing block has an avoidance groove that matches the right half of the slider.

[0015] Furthermore, the locking mechanism includes a base with a concave cross-section, a pair of opposing latches that can slide within the base at its upper end, and a second spring located within the base at the rear end of the latches.

[0016] The beneficial effects of this utility model are as follows: Through the cooperation of the pin mechanism and the locking mechanism, this utility model enables the character plate and the LED light source plate to be independently disassembled and installed on the housing by pressing.

If the specific posture changes, the directional indicator will also change accordingly.

[0029] See Figure 1-3As shown, a splicing type outdoor LED illuminated signboard includes a housing 1 with its front and rear ends connected. A character plate 2 is provided at the front end of the housing 1, and an LED light source plate 3 is provided at the rear end of the housing 1. A light-transmitting plate 4 is provided inside the housing 1 between the character plate 2 and the LED light source plate 3. Locking holes 23 are respectively provided on the character plate 2 and the LED light source plate 3, and a pin mechanism 5 that can move inward and outward passes through the locking holes 23. A hollow cavity 11 is formed at the upper and lower ends of the housing 1, and a locking mechanism 6 adapted to the pin mechanism 5 is respectively provided on the bottom surface of the hollow cavity 11. During installation, the character plate 2 and the LED light source plate 3 are detachably locked to the housing 1 through the cooperation of the pin mechanism 5 and the locking mechanism 6.

[0030] Further, see Figure 1 and Figure 3 As shown, in this embodiment, a cover plate 7 is provided at the opening of the hollow chamber 11, and the cover plate 7 is detachably locked at the opening of the hollow chamber 11.

[0031] Further, see Figure 3 As shown, in this embodiment, both the character plate 2 and the LED light source plate 3 are embedded in the housing 1, and neither the front end face of the character plate 2 nor the rear end face of the LED light source plate 3 protrudes from the housing 1. When it is necessary to remove the character plate 2 and the LED light source plate 3, an internal thread is provided in the locking hole 23 to facilitate the removal of the character plate 2 and the LED light source plate 3 from the housing 1. When removing them, the front end of the screw or bolt is screwed into the locking hole 23 and pulled outward.

[0032] Further, see Figure 4-7 As shown, in this embodiment, the pin mechanism 5 includes a pin 51, which is a stepped shaft composed of a first stepped segment 511, a second stepped segment 512, a third stepped segment 513, and a fourth stepped segment 514 with successively decreasing outer diameters. The outer surface of the fourth stepped segment 514 is provided with external threads. A first spring 52 is sleeved on the outer surface of the second stepped segment 512. A slider 53 that can slide on the third stepped segment 513 is sleeved on it. A fixing block 54 is threadedly connected to the front end of the fourth stepped segment 514. During installation, the pin 51 passes through the locking hole 23. At this time, the first spring 52 is located between the bottom surface of the locking hole 23 and the first stepped segment 511.

[0033] See also Figure 4-7As shown, in this embodiment, the left and right halves of the slider 53 contract inward, and the contraction angles of the left and right halves are the same; the outer surface of the fixing block 54 is an arc surface, and the fixing block 54 has an avoidance groove 541 that is adapted to the right half of the slider 53; when the slider 53 slides up and down along the third step 513, the right half of the slider 53 can sink into the avoidance groove 541.

[0034] Further details can be found by referring to [link / reference]. Figure 4-7 As shown, in this embodiment, the locking mechanism 6 includes a base 61 with a concave cross-section. A pair of opposing locking tongues 62 are provided on the upper end of the base 61 and can slide within it. A second spring 63 is provided in the base 61 at the rear end of the locking tongues 62. Under the action of no external force, the second spring 63 has a tendency to drive the pair of locking tongues 62 to move closer together.

[0035] The working principle of this utility model is as follows:

[0036] In use, after embedding the character plate 2 with the corresponding characters into the housing 1 as needed, refer to... Figure 4 As shown, the pin mechanism 5 is inserted into the locking hole 23, and the pin 51 is pressed inward. At this time, as the pin 51 is pressed into the locking hole 23, the fixing block 54 squeezes a pair of locking tongues 62 to slide into the base 61. After the fixing block 54 completely passes the pair of locking tongues 62, the pair of locking tongues 62, under the rebound force of the second spring 63, drive the locking tongues 62 to move outward and directly reset, making a "click" sound. At this point, the pressing of the pin 51 is stopped, and the pin 51 moves outward under the rebound force of the first spring 52 until the upper end face of the fixing block 54 abuts against the locking tongues 62, thus achieving locking. Figure 5 As shown.

[0037] When the character plate 2 needs to be replaced, first press the pin 51 into the locking hole 23 until it is fully depressed. During this pressing process, a pair of locking tongues 62 first abut against the slider 53 and drive the slider 53 to slide on the third step 513 until the upper end of the slider 53 abuts against the stepped surface between the second step 512 and the third step 513. Then, the slider 53 pushes the pair of locking tongues 62 into the base 61. After the right half of the slider 53 passes the pair of locking tongues 62, the pair of locking tongues 62 are driven to move outward and reset under the rebound force of the second spring 63. It should be noted that, in the design, it is necessary to ensure that when the pin 51 is pressed to the lowest point, the stepped surface between the second step 512 and the third step 513 does not contact the pair of locking tongues 62. Figure 6As shown; then release the pressure on the pin 51. At this time, as the pin 51 moves outward under the rebound force of the first spring 52, a pair of locking tongues 62 push against the left half of the slider 53, driving the slider 53 to slide along the third step 513 until the right half of the slider 53 sinks into the relief groove 541 in the fixed block 54. The slider 53 then presses the pair of locking tongues 62 to slide into the base 61. After passing the left half of the slider 53, the locking tongues 62 slide outward along the outer surface of the fixed block 54 towards the base 61, thus unlocking the device. Figure 7 As shown; after unlocking, screw the screw or bolt into the locking hole 23, then pull it out to remove the character plate 2 and replace it with the required character plate 2.

[0038] Finally, it should be noted that the installation and removal of the LED light source board 3 are the same as those of the character board 2, and will not be repeated here.

[0039] 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, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
