Description

Technical Field

[0001] This utility model belongs to the field of lighting decoration technology, specifically relating to a sealing device for neon light strips. Background Technology

[0002] Neon light strips are flexible lighting products used for decoration or illumination. They combine the visual effects of traditional neon lights with the advantages of modern LED technology. They emit light through a series of LED beads, and achieve uniform light transmission with silicone or PVC sleeves. They can be designed to be single-color, multi-color mixed light, or dynamic effects. Their sealing devices usually include plugs, waterproof sleeves, and water-guiding structures. As the direct actuator for end sealing, the plug is an essential component of the entire device. The plug is generally installed at the end of the LED or neon light strip to seal the light strip port and prevent moisture and dust from entering the internal circuit. One end of the plug is also designed with a wire outlet hole to support the passage of power cables or signal cables, adapting to different wiring needs.

[0003] Most existing neon light strip sealing plugs use pre-made wire outlet holes with only one-sided openings, which can only support unidirectional wire outlets in a specific direction (such as top or bottom). This results in poor adaptability to wiring in different directions. Customizing plugs with different opening directions would lead to a variety of models, making storage and retrieval time-consuming and troublesome. Utility Model Content

[0004] The purpose of this utility model is to provide a neon light strip sealing device. By rotating the hemispherical cover, the position and orientation of the conduit can be changed axially. It can adapt to the actual wiring needs from multiple angles, eliminating the need to specially customize sealing plugs with different opening directions. The unified assembly model makes storage and retrieval more time-saving and convenient.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A neon light strip sealing device includes a hemispherical cover that is detachably and rotatably assembled on one side of a plug. The bottom and sidewalls of the hemispherical cover extend inward to form a conduit, and a sealing post is frictionally fitted into the inner wall of the conduit.

[0007] The plug is a polygonal shell, the diameter of the hemispherical cover is smaller than the side length of the plug, and the axes of the two conduits form a 90° angle.

[0008] One end of the plug is fixedly connected to an internal threaded tube, and the outer wall of the internal threaded tube is threadedly connected to an external threaded tube.

[0009] The inner wall of the end of the external spiral tube is rotatably connected to a rotating shaft tube, one end of which extends to the outside of the external spiral tube and is fixedly connected to the folded part of the hemispherical cover.

[0010] The folded part of the hemispherical cover and the bottom outer wall of the outer spiral tube are both circumferentially fixed with friction blocks, and the two friction blocks are distributed in a vertical mirror image.

[0011] A sealing ring is provided at the junction of the hemispherical cover and the outer spiral tube, and the sealing ring is movably sleeved on the outer wall of the end of the rotating shaft tube.

[0012] The sealing post is designed as a variable-diameter stepped column structure, with its large-diameter end fitting against the outer wall of the hemispherical cover, and its small-diameter end fixedly connected to a friction column. A sealing ring is movably sleeved on the outer wall of the sealing post.

[0013] The technical advantages achieved by this utility model are as follows: the axial orientation of the conduit can be changed by rotating the hemispherical cover, which can adapt to the actual wiring needs from multiple angles. There is no need to specially customize sealing plugs with different opening directions, and the assembly model is standardized, making storage and retrieval more time-saving and convenient.

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figures 1-6 As shown, a neon light strip sealing device includes a hemispherical cover 102 detachably and rotatably assembled on one side of a plug 1. The plug 1 is a polygonal shell. The bottom and sidewalls of the hemispherical cover 102 extend inward to form conduits 107. The axes of the two conduits 107 form a 90° angle. A sealing post 108 is frictionally fitted into the inner wall of the conduit 107. The diameter of the hemispherical cover 102 is smaller than the side length of the plug 1. An inner threaded tube 101 is fixedly connected to one end of the plug 1. An outer threaded tube 104 is threadedly connected to the outer wall of the inner threaded tube 101. A rotating shaft tube 103 is rotatably connected to the inner wall of the end of the outer threaded tube 104. One end of the rotating shaft tube 103... Extending to the outside of the outer spiral tube 104 and fixedly connected to the folded part of the hemispherical cover 102, the folded part of the hemispherical cover 102 and the bottom outer wall of the outer spiral tube 104 are both circumferentially fixedly connected with friction blocks 105. The two friction blocks 105 are vertically mirrored. A sealing ring 106 is provided at the junction of the hemispherical cover 102 and the outer spiral tube 104, and the sealing ring 106 is movably sleeved on the end outer wall of the rotating shaft tube 103. The sealing column 108 is designed as a variable diameter stepped column structure, with its large diameter end fitting against the outer wall of the hemispherical cover 102, and its small diameter end fixedly connected to a friction column 110. A sealing ring 109 is movably sleeved on the outer wall of the sealing column 108.

[0024] According to the above structure, when threading the cable, rotate the outer helix 104 to separate it from the inner helix 101, and pass the cable through the plug 1 and friction block 105 in sequence into the hemispherical cover 102. After pinching the outer helix 104, rotate the hemispherical cover 102. The rotating shaft tube 103 rotates in the annular groove matched in the inner wall of the outer helix 104. The friction block 105 at the bottom of the outer helix 104 rubs against the friction block 105 at the flipped part of the hemispherical cover 102, so that the rotation produces a damping effect, which can prevent the hemispherical cover 102 from rotating randomly without interference.

[0025] Furthermore, a sealing ring 106 is disposed between the flipping part of the hemispherical cover 102 and the rotating shaft tube 103, that is, at the junction of the hemispherical cover 102 and the outer spiral tube 104, to prevent moisture from seeping in through the junction. Two wire tubes 107 are respectively opened at the bottom and side wall of the hemispherical cover 102. The angle of the wire tube 107 on the side wall changes with the rotation of the hemispherical cover 102 to adapt to different routing directions. The orientation of the wire tube 107 at the bottom of the hemispherical cover 102 remains unchanged, which makes up for the orientation defect of the wire tube 107 on the side wall in the vertical direction. Depending on the actual routing direction, the cable is selected to be passed out from the wire tube 107 on the side wall or the wire tube 107 at the bottom. The unused one is sealed by inserting a sealing post 108. Then the outer spiral tube 104 and the inner spiral tube 101 are screwed together and fixed.

[0026] Furthermore, the friction column 110 uses a flexible material (such as rubber, silicone, etc.) to fit into the inner wall of the conduit 107 through friction. When the sealing column 108 is inserted into the conduit 107, its larger diameter end is attached to the outer wall of the hemispherical cover 102 for initial waterproofing and dustproofing. The sealing ring 109 on the outer wall of the sealing column 108 provides secondary protection inside the conduit 107. The diameter of the hemispherical cover 102 is smaller than the side length of the plug 1, which can prevent the light strip from not being able to adhere to the plate when it is installed with the plate because the diameter of the hemispherical cover 102 is too large.

[0027] This utility model can change the axial position and orientation of the conduit 107 by rotating the hemispherical cover 102, which can adapt to the actual wiring needs from multiple angles. It eliminates the need to specially customize sealing plugs 1 with different opening directions, and unifies the assembly model, making storage and retrieval more time-saving and convenient.

[0028] The working principle of this utility model is as follows: When threading the cable, rotate the outer helical tube 104 to separate it from the inner helical tube 101, and pass the cable through the plug 1 and friction block 105 in sequence into the hemispherical cover 102. After pinching the outer helical tube 104, rotate the hemispherical cover 102. The rotating shaft tube 103 rotates in the annular groove matched in the inner wall of the outer helical tube 104. The friction block 105 at the bottom of the outer helical tube 104 rubs against the friction block 105 at the flipped part of the hemispherical cover 102, so that the rotation produces a damping effect, which can prevent the hemispherical cover 102 from rotating randomly without interference.

[0029] Furthermore, a sealing ring 106 is disposed between the flipping part of the hemispherical cover 102 and the rotating shaft tube 103, that is, at the junction of the hemispherical cover 102 and the outer spiral tube 104, to prevent moisture from seeping in through the junction. Two wire tubes 107 are respectively opened at the bottom and side wall of the hemispherical cover 102. The angle of the wire tube 107 on the side wall changes with the rotation of the hemispherical cover 102 to adapt to different routing directions. The orientation of the wire tube 107 at the bottom of the hemispherical cover 102 remains unchanged, which makes up for the orientation defect of the wire tube 107 on the side wall in the vertical direction. Depending on the actual routing direction, the cable is selected to be passed out from the wire tube 107 on the side wall or the wire tube 107 at the bottom. The unused one is sealed by inserting a sealing post 108. Then the outer spiral tube 104 and the inner spiral tube 101 are screwed together and fixed.

[0030] Furthermore, the friction column 110 uses a flexible material (such as rubber, silicone, etc.) to fit into the inner wall of the conduit 107 through friction. When the sealing column 108 is inserted into the conduit 107, its larger diameter end is attached to the outer wall of the hemispherical cover 102 for initial waterproofing and dustproofing. The sealing ring 109 on the outer wall of the sealing column 108 provides secondary protection inside the conduit 107. Since the diameter of the hemispherical cover 102 is smaller than the side length of the plug 1, it can prevent the light strip from not being able to adhere to the plate when it is installed with the plate because the diameter of the hemispherical cover 102 is too large.

[0031] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
