[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. It should be understood that the preferred embodiments described herein are only for illustration and explanation of the present utility model and are not intended to limit the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The components of the embodiments of the present utility model described and shown in the accompanying drawings can be arranged and designed in various different configurations. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model. In the embodiments, the components of the embodiments of the present application described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of the present application.

[0022] See Figures 1 to 6 As shown, a waterproofing device for an exposed point light source sign includes a base 1 and a fixing frame 2. Support legs are provided on the bottom surface of the base 1, and the sign 3 is located above the base 1. The base 1 has a cavity inside, and a rolled-up waterproof membrane 4 is placed inside the cavity. An opening is provided on the upper surface of the base 1, and the end of the waterproof membrane 4 can extend out from the opening on the upper surface of the base 1. Then, the waterproof membrane 4 is covered on the light-emitting surface of the sign 3, and the fixing frame 2 is installed on the sign 3. At this time, the waterproof membrane 4 is positioned, and the waterproof membrane 4 plays a waterproofing role, preventing rainwater and other substances from seeping into the sign 3.

[0023] A boss 5 is fixed on the upper surface of the base 1. The boss 5 is connected to a seat plate 6, which is fixed on the upper surface of the boss 5. The sign is installed on the seat plate 6. At this time, there is a closed gap between the seat plate 6 and the base 1. A rotating shaft 7 is provided in the cavity of the base 1. The two ends of the rotating shaft 7 are connected to the side surfaces of the cavity, so that the rotating shaft 7 can rotate. One end of the waterproof membrane 4 is connected to the rotating shaft 7 and wrapped around the rotating shaft 7. The other end of the waterproof membrane 4 extends outward from the opening. The width of the extended waterproof membrane 4 is greater than the width of the light-emitting surface of the leaky light source sign, and the length of the waterproof membrane is also greater than the length of the light-emitting surface. That is, the waterproof membrane 4 can cover the light-emitting surface. The waterproof membrane 4 is made of a transparent and soft material, so that the light of the leaky light source sign can shine outward through the waterproof membrane 4.

[0024] In order to ensure that the waterproof membrane 4 can tightly wrap the light-emitting surface of the leaking light source sign, the fixing frame 2 can move towards the sign 3 and eventually fit onto the sign. The fixing frame 2 is connected to the base 1 by two slide rails 8. A slide seat 9 is fixed on the fixing frame 2. A rail groove is provided on the bottom surface of the slide seat 9. The slide rail fits into the rail groove, allowing the slide seat to move along the slide rail towards the sign. Finally, the bottom of the fixing frame 2 and the slide seat 9 are both located within the closed interval. At this time, the fixing frame 2 fits onto the connecting body composed of the sign 3 and the base plate 6. A cover plate 10 is provided on the bottom surface of the slide seat. The cover plate 10 is located between the two slide rails 8. When the fixing frame 2 fits onto the connecting body composed of the sign 3 and the base plate 6, the cover plate 10 seals the opening on the base 1, thereby preventing rainwater from entering the cavity of the base.

[0025] The fixed frame 2 can be in the shape of a square or a ring. The shape of the fixed frame 2 is set according to the shape of the connection between the leak light source sign and the base plate. After the fixed frame 2 is connected to the connecting body composed of the sign 3 and the base plate 6, the inner wall of the fixed frame 2 is tightly fitted with the outer side of the connecting body. That is, the fixed frame 2 covers the sign and the base plate. At this time, the waterproof membrane 4 is located between the fixed frame 2 and the connecting body, which plays a role in fixing the waterproof membrane.

[0026] In addition, to make the waterproof membrane 4 adhere more tightly to the connector, a sealing strip 11 is installed at the contact position between the fixing frame 2 and the connector. The sealing strip 11 has a right-angled triangle cross section and an adhesion eave 12 is connected to the strip. The adhesion eave 12 is long and has a round hole. The fixing frame 2 has a threaded through hole. The bolt 13 can be passed through the round hole on the adhesion eave 12 and screwed into the threaded through hole on the fixing frame 2. As the bolt 13 is gradually tightened, the gap between the adhesion eave 12 and the fixing frame 2 gradually decreases, so that the sealing strip 11 gradually extends into the gap between the fixing frame 2 and the connector, and finally forms a seal. At this time, a closed space is formed between the waterproof membrane 4 and the connector, and the fixing frame and the connector form a relatively stable connection.

[0027] In addition, to further improve the coverage of the waterproof membrane 4 with the leaking light source sign, a vacuum pump 14 is installed in the cavity of the waterproof base. The bottom of the vacuum pump 14 is installed on the inner wall of the waterproof base, and there is a certain gap between the vacuum pump 14 and the waterproof membrane 4. A horizontal through-hole is provided on the base plate. When the waterproof membrane covers the light-emitting surface, the vacuum pump is connected to the suction pipe 15, and the other end of the suction pipe is connected to the air hole. A locking valve is provided on the suction pipe 15. When the vacuum pump 14 works, it extracts the air between the waterproof membrane 4 and the leaking light source sign, so that a vacuum state is formed, and the waterproof membrane will be completely adhered to the leaking light source sign.

[0028] An isolation frame located within a sealed space is provided on the seat plate 6. The isolation frame consists of a long strip and a support rod. The long strip is parallel to the side of the seat plate 6, and the support rod is located between the long strip and the seat plate. At this time, the long strip is located on the extension line of the air hole. When the sealed space is evacuated through the air hole, the gas in the sealed space flows through the space between the long strip and the seat plate and then enters the air hole.

[0029] When the waterproof membrane 4 protects the sign, because the material of the waterproof membrane is relatively soft, in extreme weather conditions such as hail or strong winds, the stones and other debris blown by hail or strong winds will scratch the waterproof membrane. This application installs a protective net on the fixed frame 2. The protective net is located on the outside of the waterproof membrane. The protective net is made of hard transparent material, such as plastic or resin. That is, the protective surface is both light-transmitting and has a certain degree of hardness.

[0030] As a further improvement of this utility model, when the sign is a cuboid, two vertically extending grooves are provided on the fixed frame. The two grooves are parallel and both are vertical. The fixed frame is connected to a flat frame 16 through the two grooves. The flat frame 16 is fitted onto the fixed frame 2. A protrusion is provided on the inner side wall of the flat frame 16. The protrusion is located in the groove, and the flat frame 16 can move vertically. A linear groove is provided on the flat frame 16. An adhesive strip can be installed in the linear groove. When the waterproof membrane 4 is pulled outward, the upper end of the waterproof membrane 4 covers the linear groove of the flat frame 16, and then the adhesive strip is inserted into the linear groove. At this time, the flat frame 16 is connected to the waterproof membrane 4. Then the flat frame 16 is slid upward to pull out the waterproof membrane 4. In this process, only one end of the flat frame 16 needs to be applied upward. When the flat frame moves to the upper end of the groove, the flat frame is located above the sign.

[0031] In practical applications, not only can the air in the sealed space be extracted by the vacuum pump 14, but the vacuum pump can also be replaced by an air pump to input gas into the sealed space. This will create a certain gap between the protective film and the light-emitting surface, which can prevent hail from directly hitting the light-emitting surface when encountering weather such as hail. Since the waterproof film has a certain degree of flexibility, it is not easily damaged. However, it should be noted that sealant should be applied to the contact area between the waterproof film and the connector.

[0032] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to an electrical connection; they can refer to a hydraulic connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be primarily defined by the scope of the claims.
