[0002] In the light string assembly, each lamp bead and its connecting wire need to be provided with a lamp string sheath outside, which is usually made of insulating rubber or plastic, and can not only play a good positioning and buffering role for the internal lamp bead, but also has the effects of heat insulation, flame retardancy, dust prevention, etc. A Chinese patent with publication number CN203162658U and publication date 2013-08-28 discloses an LED lamp kit, including a light guide sleeve and a lamp holder arranged at the bottom of the light guide sleeve, the sleeve is arranged with white heat dissipation grooves, and the bottom is connected to the conductive column part of the lamp bead through a threaded positioning structure.
[0003] In the above scheme, during the operation of the light string, the heat on the lamp beads can be discharged in time through the heat dissipation grooves, so the lamp beads have good heat dissipation performance. However, it is precisely because the multiple heat dissipation grooves on the sleeve make the sleeve connected inside and outside. When the light string is installed outdoors, low-temperature air, moisture, dust, etc. from the outside can easily enter the sleeve, thereby polluting or corroding the internal lamp beads and circuit components, reducing the overall service life of the light string. Utility Model Content

[0007] In the above technical solution, the adjustable lamp holder can be positioned by setting the positioning sleeve, and the lamp beads are installed on the lamp holder. The positioning sleeve is provided with heat dissipation holes, and when the light string is in working state, heat can be dissipated through the heat dissipation holes, thereby maintaining good heat dissipation performance.

[0030] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.
[0031] Embodiment 1:
[0032] The embodiments of the present application provide an outdoor moisture-proof light string cover, which aims to solve the problem that the light string cover in the prior art is easily invaded by external humid air and dust when used outdoors, causing pollution or erosion to the internal lamp beads and circuit components. It not only has good heat dissipation performance, but also has the advantages of moisture resistance and dust resistance.
[0033] See also Figures 1 to 3The outdoor moisture-proof light string sheath specifically includes a positioning sleeve 1, an isolation bushing 2 and an adjustable lamp holder 5, wherein the positioning sleeve 1 includes a fixing ring 11 and two mounting walls 12 arranged at the lower part of the fixing ring 11, and the mounting wall 12 is in the shape of a bearing. Here, the mounting wall 12 can be integrally connected to the fixing ring, or can be connected to the fixing ring 11 by screws. The two mounting walls 12 are arranged opposite to each other in the circumferential direction and a heat dissipation hole 14 is formed between adjacent mounting walls 12. The adjustable lamp holder 5 is arranged in the inner cavity of the positioning sleeve 1 for positioning the lamp bead. The isolation sleeve 2 can be rotatably sleeved on the outer side of the positioning sleeve 1, and the isolation sleeve 2 includes two opposite partition walls 21, and an arc-shaped connecting strip 23 is arranged between adjacent partition walls 21. When the isolation sleeve 2 rotates relative to the positioning sleeve 1, the partition walls 21 can cover the corresponding heat dissipation holes 14, and a circumferential limiting mechanism can be operably arranged between the isolation sleeve 2 and the positioning sleeve 1 to limit the position of the isolation sleeve 2 when the partition walls 21 cover and detach from the heat dissipation holes 14.
[0034] In this embodiment, when assembling the lamp beads on the light string, the adjustable lamp holder 5 can be first taken out from the positioning sleeve 1, the lamp beads can be installed on the lamp holder, and then the adjustable lamp holder 5 can be inserted into the inner cavity of the positioning sleeve 1 through the tapered hole, and the positioning sleeve 1 can position the adjustable lamp holder 5. The positioning sleeve 1 is provided with heat dissipation holes 14. When the lamp beads are in the heat dissipation state, that is, the light string is in the working state, refer to Figure 2 As shown, heat can be dissipated through the heat dissipation holes 14, thereby maintaining good heat dissipation performance. By setting the isolation bushing 2, when the light string is used outdoors, it is in a non-working state, that is, in a covered state, referring to Figure 1 As shown, the isolating bushing 2 is rotated to cover the partition wall 21 on the heat dissipation hole 14, so as to prevent external humid air or dust particles from entering the inner cavity of the positioning jacket 1 to corrode and damage the lamp beads, thereby extending the service life of the light string.
[0035] It should be noted that the positioning jacket 1 is cylindrical as a whole, and only two mounting walls 12 are provided here. In other embodiments, three or more mounting walls 12 may be provided, and they are arranged at equal angles and evenly distributed along the circumference, and heat dissipation holes 14 are formed between two adjacent mounting walls 12. Correspondingly, the semi-ring support feet 13 are replaced with fan-shaped support feet, and the number of partition walls 21 on the isolation bushing 2 is consistent with the number of heat dissipation holes 14, and the rotation of the isolation bushing 2 can make each partition wall 21 cover the corresponding heat dissipation hole. Although this makes the processing difficulty of the jacket higher, the structural stability is also improved, and the technical purpose of detachably covering the corresponding heat dissipation holes can also be achieved. The technicians can make a choice according to the design requirements.
[0036] refer to Figure 3As shown, in this embodiment, an inner ring 4 is connected to the inner wall of the positioning sleeve 1 through a thread, the inner ring 4 is located at the top of the inner cavity of the positioning sleeve 1, and a rubber support 41 is provided on the inner ring 4. The middle part of the rubber support 41 is hollow and the lampshade part of the lamp bead can pass through the hollow part, so as to support the lampshade part of the lamp bead.
[0037] In this embodiment, the adjustable lamp holder 5 is connected to the positioning sleeve 1 by threads, so that the longitudinal position of the adjustable lamp holder 5 in the inner cavity of the positioning sleeve 1 can be adjusted, so that lamp beads of different heights and sizes within a certain range can be installed in the inner cavity of the positioning sleeve 1, which increases the flexibility and adaptability of the sleeve. Specifically, the adjustable lamp holder 5 includes an integrally connected mounting portion 51 and a lead portion 52, the outer side of the mounting portion 51 is connected to the inner wall of the positioning sleeve 1, and the lead portion 52 has a through hole for the line to pass through. Here, since the adjustable lamp holder 5 can be taken out of the positioning sleeve 1, it is convenient to install the lead bracket of the lamp bead into the inner groove of the mounting portion 51, and at the same time, the line is passed through the lead portion 52 and connected to the lead bracket, making the installation process of the lamp bead more convenient.
[0038] refer to Figures 4 to 5 As shown, in this embodiment, the mounting wall 12 is made of elastic plastic material, and the lower part of each mounting wall 12 has a semi-ring support foot 13, and a tapered hole 134 for guiding the adjustable lamp holder 5 into the inner cavity of the positioning sleeve 1 is formed between the two semi-ring support feet 13. The diameter of the tapered hole 134 gradually shrinks upward in the longitudinal direction, and one end of the tapered hole 134 is connected to the inner cavity of the positioning sleeve 1, and the upper edges of the two semi-ring support feet 13 form an outer ring groove 131 for supporting the isolation bushing 2 to rotate in the circumferential direction. The two semi-ring support feet 13 form a limited position surface 132 on the side opposite to the inner cavity of the positioning sleeve 1 for supporting the mounting portion 51 of the adjustable lamp holder 5.
[0039] When assembling the lamp bead and the sheath, the lamp bead can be first installed on the adjustable lamp holder 5, and the adjustable lamp holder 5 enters into the inner cavity of the positioning sleeve 1 along the tapered hole 134. Since the mounting wall 12 is made of elastic plastic, the aperture of the tapered hole 134 can be set to be slightly smaller than the outer diameter of the lamp holder. When the adjustable lamp holder 5 passes through the tapered hole, the semi-ring support leg 13 and the mounting wall 12 are squeezed to produce a small elastic deformation, so that the diameter of the tapered hole is expanded. This can ensure that the lamp holder is smoothly installed in the positioning sleeve 1, and can also form a certain clamping force on the lower end of the lamp holder, so that the assembled light string structure is more stable and reliable.
[0040] In this embodiment, the circumferential limiting mechanism includes a plurality of positioning notches 133 arranged on the groove wall of the outer ring groove 131, and the connecting strip 23 is provided with an elastic clamping arm 232 that matches the positioning notch 133. Further, a plurality of connecting strips 23 are arranged in the longitudinal direction between adjacent partition walls 21, and the bottom connecting strip 23 and the outer ring groove 131 are at the same height, and the elastic clamping arm 232 is arranged on the side wall of the bottom connecting strip 23, and the elastic clamping arm 232 has two opposite buckle parts, and the buckle part is detachably engaged with the positioning notch 133.
[0041] For the convenience of operation, the connecting strip 23 is provided with an operating protrusion 231 for the operator to apply a rotational operating force to the isolation bushing 2. When the light string is in operation, the operator turns the operating protrusion 231 counterclockwise or clockwise to drive the isolation bushing 2 to rotate, so that the partition wall 21 gradually rotates to cover the adjacent heat dissipation hole, or gradually moves away from the heat dissipation hole and overlaps with the mounting wall 12 of the internal positioning jacket 1.
[0042] In this embodiment, the upper part of the fixing ring 11 is connected to the outer ring cover 3 by threads, and the isolation bushing 2 is positioned longitudinally between the outer ring cover 3 and the outer ring groove 131. More specifically, the fixing ring 11, the mounting wall 12 and the semi-ring support foot 13 are integrally formed and connected.
[0043] In this embodiment, when it is necessary to install one of the lamp beads of the lamp string into the protective sleeve, first remove the outer ring cover 3, separate the isolation bushing 2 from the positioning sleeve 1, take out the adjustable lamp holder 5 from the positioning sleeve 1, and assemble the adjustable lamp holder 5 and the lamp bead first. After completion, squeeze the adjustable lamp holder 5 into the inner cavity of the positioning sleeve 1 along the tapered hole 134, and then move the adjustable lamp holder 5 through the heat dissipation hole to adjust the height of the adjustable lamp holder 5 so that the lampshade part of the upper part of the lamp bead passes through the rubber support 41, and the hard rubber sheet on the rubber support 41 is pressed against the outside of the lampshade, thereby supporting the lamp bead, and then install the isolation bushing 2. After the lower part of the isolation bushing 2 is against the outer ring groove 131, the outer ring cover 3 is connected to the fixing ring 11, and the isolation bushing 2 is positioned between the outer ring cover 3 and the outer ring groove 131.
[0044] In summary, in this embodiment, the positioning jacket 1 is provided with heat dissipation holes 14, and when the lamp beads are in a heat dissipation state, heat can be dissipated through the heat dissipation holes 14, thereby maintaining good heat dissipation performance. By providing the isolation bushing 2, when the light string is used outdoors and is in a non-working state, the isolation bushing 2 can be rotated to cover the partition wall 21 on the heat dissipation hole 14, thereby preventing external humid air or dust particles from entering the inner cavity of the positioning jacket 1, corroding and damaging the lamp beads, thereby extending the service life of the light string.
[0045] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model.
