[0022] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0023] The built-in waterproof structure of the embodiment of the utility model is described in detail below with reference to the accompanying drawings. Example

[0024] For easier understanding, see Figures 1 to 5 An embodiment of a built-in waterproof structure provided by the utility model comprises an external pressure ring 1, a waterproof ring 2, an internal pressure nut 3, a waterproof plug 4 and an internal pressure ring 5, wherein the waterproof ring 2, the internal pressure nut 3 and the internal pressure ring 5 are sequentially installed on the outer wall of the external pressure ring 1, the waterproof plug 4 is located on the inner wall of the external pressure ring 1, and the internal pressure ring 5 abuts against one end of the waterproof plug 4, and the waterproof structure composed of the external pressure ring 1, the waterproof ring 2, the internal pressure nut 3, the waterproof plug 4 and the internal pressure ring 5 is installed on the lamp body 6 of the outdoor waterproof lamp.

[0025] The waterproof plug 4 is made of a highly elastic material and deforms when supported by the inner pressure ring 5 , so that the waterproof plug 4 is tightly filled in the inner wall of the outer pressure ring 1 .

[0026] The waterproof ring 2 is sleeved on the outer wall of the outer pressure ring 1 by interference fit, and the waterproof ring 2 is supported on one end of the lamp body 6 on which the side wall of the outer pressure ring 1 is installed;

[0027] In addition, one end of the internal pressure nut 3 is supported on the other end of the lamp body 6 to ensure the sealing and stability of the entire structure.

[0028] It should be noted that the built-in waterproof structure is suitable for the lamp body 6 of outdoor waterproof lamps. The waterproof ring 2 is sleeved on the outer wall of the external pressure ring 1 by interference fit, and supported on one end of the lamp body 6 on which the external pressure ring 1 is installed. Next, the internal pressure nut 3 is tightened onto the standard thread on the outer wall of the external pressure ring 1 until one end of the internal pressure nut 3 is supported on the other end of the lamp body 6, thereby ensuring the sealing and stability of the entire structure. Afterwards, the waterproof plug 4 is placed on the inner wall of the external pressure ring 1. The waterproof plug 4 is made of a highly elastic material to ensure that the waterproof plug 4 can be deformed when subjected to force, thereby tightly filling the inner wall of the external pressure ring 1.

[0029] In some embodiments, the end of the outer pressure ring 1 that contacts the waterproof plug 4 is a conical or arc-shaped surface.

[0030] It should be noted that in order to further enhance the sealing effect, the end of the outer pressure ring 1 that contacts the waterproof plug 4 is formed into a conical or arc-shaped surface. When the inner pressure ring 5 is installed in place and contacts one end of the waterproof plug 4, the waterproof plug 4 will be deformed, thereby fitting more closely to the inner wall of the outer pressure ring 1 to achieve good waterproof performance.

[0031] In some embodiments, the outer wall of the outer pressure ring 1 is provided with a standard thread, and the standard thread matches the inner wall thread of the inner pressure nut 3 and the inner pressure ring 5 to form a tight mechanical connection.

[0032] It should be noted that the standard thread matches the inner wall thread of the inner pressure nut 3 and the inner pressure ring 5, thereby forming a tight mechanical connection, which not only facilitates assembly but also strengthens the integrity of the structure.

[0033] Working principle: The waterproof ring 2 is installed on the outer wall of the outer pressure ring 1 through interference fit and supported on one end of the lamp body 6. The function of the waterproof ring 2 is to form a sealing barrier between the outer pressure ring 1 and the lamp body 6. The internal pressure nut 3 is tightened on the standard thread of the outer pressure ring 1 and supported on the other end of the lamp body 6 to ensure a tight connection between the outer pressure ring 1 and the lamp body 6, further enhancing the overall sealing.

[0034] The waterproof plug 4 is made of highly elastic material and is placed on the inner wall of the outer pressure ring 1. When the inner pressure ring 5 is installed in place and contacts the waterproof plug 4, since the end of the outer pressure ring 1 that contacts the waterproof plug 4 is designed to be a conical or arc-shaped surface, the waterproof plug 4 is subjected to the pressure from the inner pressure ring 5 and deforms.

[0035] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
