Description

Technical Field

[0001] The utility model relates to the field of luminous characters, in particular to a waterproof LED luminous character structure. Background Art

[0002] Luminous characters are fonts that can produce a bright effect at night or in dim environments. They are widely used in outdoor advertising, displays, celebrations and other fields to increase product visibility and attract consumers' attention.

[0003] A light source is arranged on the installation plane according to the shape of the luminous characters, and then the cover of the luminous characters is fixed by bolts to realize the installation of the luminous characters. However, moisture can easily penetrate into the gap between the cover and the installation plane, and the light source is prone to failure, affecting normal operation. This phenomenon often occurs on outdoor billboards. The purpose of the utility model is to propose a luminous character structure to solve the above problem. Utility Model Content

[0004] The utility model aims to provide a waterproof LED luminous character structure to solve the problems mentioned in the background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: including a cover shell, a base and an elastic sealing strip, the cover shell is provided with inclined bending pieces on both sides of the bottom end, the cover shell can be sleeved on the base, the bottom surface of the base is provided with a mounting hole for accommodating the light source, and water retaining pieces are provided on both sides of the top end of the base, the water retaining pieces can cooperate with the inner side of the cover shell, and the elastic sealing strips are arranged in pairs and are respectively arranged on both sides of the bottom surface of the base.

[0006] To optimize the above technical solution, further measures are taken: it also includes a bending part, the water retaining plate is connected to the top of the base through the bending part, the bending part is curved and the thickness of the bending part is less than the thickness of the base, and the purpose of setting the bending part is to improve the flexibility of the water retaining plate.

[0007] As a further improvement of the utility model, a toothed limit strip is provided on the side of the water retaining plate, and the toothed limit strip is distributed one up and one down on the outside of the water retaining plate. The toothed limit strip can cooperate with the inner side of the cover shell. The toothed limit strip can limit the cover shell to prevent the cover shell from falling off the base.

[0008] As a further improvement of the utility model, the water retaining plate is concavely formed with strip-shaped grooves between the toothed limit strips, and the strip-shaped grooves are filled with moisture-absorbing cotton strips. The purpose of providing the moisture-absorbing cotton strips is to absorb the infiltrated water vapor to prevent the water vapor from affecting the normal operation of the light source.

[0009] Preferably, the cross-section of the elastic sealing strip is a hollow trapezoid. Such a structure helps the elastic sealing strip to deform. When the operator fixes the base on a plane, the easier it is for the elastic sealing strip to deform, the easier it is for the elastic sealing strip to engage with the plane, which helps to improve the water-blocking and waterproof performance of the elastic sealing strip.

[0010] As a further improvement of the utility model, a magnetic sheet is embedded in the water baffle, and the magnetic sheet and the water baffle are parallel to each other. When the operator needs to remove the cover, he uses a magnet with opposite magnetic properties to the magnetic sheet to move closer to the water baffle. Since the magnet sheet with opposite magnetic properties will drive the water baffle away from the magnet, the operator can easily remove the cover.

[0011] Preferably, the cross-section of the toothed limiting strip is triangular, which is convenient for installation and can limit the cover shell to prevent the cover shell from separating from the base.

[0012] From the above description of the structure of the utility model, it can be seen that compared with the prior art, the utility model has the following advantages:

[0013] The utility model provides a waterproof LED luminous character structure, which utilizes components such as a bending piece, a water retaining piece, a toothed limit strip and an elastic sealing strip to cooperate with each other, and can effectively block water vapor to prevent water vapor from entering the luminous character and causing damage to the light source. At the same time, the luminous character is composed of a detachable cover shell and a base, which will not hinder the maintenance and repair of the luminous character.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example

[0021] See also Figure 1-3 The utility model provides a waterproof LED luminous character structure, including a cover shell 1, a base 2, an elastic sealing strip 3 and a bent portion 4. The cover shell 1 is provided with inclined bending pieces 101 on both sides of the bottom end. The cover shell 1 can be sleeved on the base 2. The bottom surface of the base 2 is provided with a mounting hole 201 for accommodating a light source. Water retaining pieces 202 are provided on both sides of the top of the base 2. The water retaining pieces 202 can cooperate with the inner side of the cover shell 1. The water retaining piece 202 is connected to the top of the base 2 through the bent portion 4. A magnetic piece 206 is embedded in the water retaining piece 202. The magnetic piece 206 and the water retaining piece 202 are mutually connected. Parallel, a toothed limit strip 203 with a triangular cross-section is provided on the side of the water retaining piece 202, and the toothed limit strips 203 are distributed one up and one down on the outside of the water retaining piece 202, and the toothed limit strips 203 can cooperate with the inner side of the cover shell 1, and the water retaining piece 202 is concave between the toothed limit strips 203 to form a strip-shaped groove 204, and the strip-shaped groove 204 is filled with a moisture-absorbing cotton strip 205, the curved portion 4 is curved and the thickness of the curved portion 4 is less than the thickness of the base 2, and the elastic sealing strips 3 are arranged in pairs and are respectively arranged on both sides of the bottom surface of the base 2, and the cross-section of the elastic sealing strips 3 is a hollow trapezoidal shape.

[0022] The moisture-absorbing cotton strip 205 refers to a cotton strip used to absorb moisture and water. In specific implementation, technicians can choose artificial cotton or natural cotton according to actual needs. Its purpose is to absorb moisture that penetrates into the gap between the cover shell 1 and the base 2 to avoid malfunction of the light source after getting wet.

[0023] The bending piece 101 refers to a sheet-like component that can be bent and is made of elastic material, and the elastic sealing strip 3 refers to a strip-like component made of elastic material that performs a sealing function. The specific elastic material used is not a necessary technical feature and the specific composition is not the content that the applicant wants to protect. Therefore, the elastic material will not be further explained. It is worth mentioning that the bending piece 101 is inclined relative to the plane where the luminous characters are located and the hardness of the bending piece 101 is greater than the hardness of the elastic sealing strip 3.

[0024] Working principle: The operator aligns the mounting hole 201 with the light source, and then presses the base 2 on the mounting plane to deform the elastic sealing strip 3, and uses bolts or nails to pass through the base 2 to fix the base 2 to the mounting plane. At this time, the light source is located in the mounting hole 201, and the elastic sealing strip 3 is squeezed and deformed and tightly meshed with the mounting plane to effectively block water vapor and prevent water vapor from passing through the bottom of the base 2 and contacting the light source. Since the bending piece 101 is inclined, when the base 2 is fixed to the mounting plane, the bending piece 101 will press against the base 2 circumference to block the entry of water vapor.

[0025] Subsequently, the operator installs the cover shell 1 on the base 2. During the process, the bending portion 4 bends so that the toothed limit strip 203 cooperates with the inner side of the cover shell 1. The cross-section of the toothed limit strip 203 is triangular, which is easy to enter but difficult to exit. After the cover shell 1 is installed on the base 2, the toothed limit strip 203 can clamp the cover shell 1 to prevent the cover shell 1 from separating from the base 2. At the same time, the double toothed limit strip 203 can play a waterproof role and block water vapor. The moisture-absorbing cotton strip 205 can absorb water vapor that penetrates into the gap between the cover shell 1 and the base 2, further ensuring that the inside of the luminous characters is dry.

[0026] When the operator needs to remove the cover 1 to maintain the inside of the luminous characters, the operator can use a magnet block that has mutual magnetism with the magnet sheet 206 to approach the location of the water retaining plate 202. At this time, the water retaining plate 202 will drive the toothed limit strip 203 away from the inside of the cover 1 due to the magnetic repulsion. The toothed limit strip 203 no longer limits the cover 1, and the operator can easily remove the cover 1 from the base 2.

[0027] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
