AI Technical Summary
In outdoor environments, existing lamp holders are prone to short-circuit due to rainwater entering the lamp holder cavity, resulting in insufficient waterproofness.
A waterproof lamp holder is designed. By setting a connecting wall on the inner side of the lower lamp cover and an internal thread on the inner wall of the upper lamp cover, multiple sealing is performed using thread fit and waterproof rubber gasket, combined with the sealing treatment of the wire, a multiple waterproof seal structure is formed.
It effectively prevents water from flowing from the closing of the upper lampshade and the lower lampshade, improves the waterproofness of the lamp holder and prevents the occurrence of short circuits.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of lamp accessories, and particularly relates to a waterproof lamp socket. Background Art
[0002] The existing lamp socket, as Figure 2 shown, generally includes a base electrically connected to a bulb, the base is electrically connected with a wire, a lower lampshade is arranged above the base, the lower lampshade is detachably provided with an upper lampshade, and the lower lampshade and the upper lampshade are closed to form a bulb accommodation cavity. In an outdoor environment, if it rains, rainwater will flow along the upper lampshade to the joint where the upper lampshade and the lower lampshade are closed, and then enter the bulb accommodation cavity, resulting in water ingress into the bulb accommodation cavity and short circuit of the bulb. Content of the Utility Model
[0003] The technical problem to be solved by the utility model is aimed at the deficiencies of the above-mentioned prior art,
[0004] and provides a waterproof lamp socket to improve the waterproof property and prevent water from flowing in from the joint where the upper lampshade and the lower lampshade are closed.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A waterproof lamp socket includes a base, the base is provided with a bulb socket electrically connected to a bulb, the bulb socket is electrically connected with a wire extending outside the base, a cylindrical lower lampshade is arranged above the base around the bulb socket, the lower lampshade is detachably provided with a semi-elliptical upper lampshade, and the lower lampshade and the upper lampshade are closed to form an accommodation cavity for accommodating the bulb and the bulb socket. The feature is that: an inner connecting wall is arranged around the opening on the inner side above the lower lampshade, an external thread is arranged on the outer end face of the connecting wall, an internal thread is arranged on the inner wall below the opening of the upper lampshade, the internal thread is in threaded fit with the external thread, and a first waterproof rubber gasket is fixedly arranged along the lower opening of the upper lampshade.
[0006] A further setting of the utility model is that: a limiting ring is arranged around the inner wall of the lower opening of the upper lampshade, a second waterproof rubber pad is arranged at one end of the limiting ring facing the lower lampshade, and when the upper lampshade and the lower lampshade are closed until the first waterproof rubber gasket abuts against the upper opening of the lower lampshade, the second waterproof rubber pad abuts against one end of the upper connecting wall.
[0007] A further setting of the utility model is that: the wire is sealed at the place where the wire extends out of the base.
[0008] A further setting of the utility model is that: the wire is sealed between the wire extending to the base and the base through waterproof glue.
[0009] The utility model with the above characteristics: The first waterproof rubber pad plays the role of the first waterproof seal, the connecting wall plays the role of the second waterproof seal, and there is a height difference formed at the junction of the upper lamp cover and the lower lamp cover above the connecting wall, so that the water flowing to the junction of the openings of the upper lamp cover and the lower lamp cover cannot penetrate into the accommodation cavity. The second waterproof rubber gasket plays the role of the third waterproof seal. The wire extending out of the base is sealed with waterproof sealant. The waterproof sealant can fill the gap according to the shape of the wire, achieving a better sealing effect. Multiple seals make the accommodation cavity completely sealed and water-proof, avoiding short circuits caused by water ingress.
[0010] The beneficial effects of the utility model are: improving waterproof performance and preventing water from flowing in at the junction of the upper lamp cover and the lower lamp cover.
[0011] The following further details the utility model in conjunction with the drawings and embodiments. Description of the Drawings
[0012] Figure 1 It is a schematic cross-sectional view of an embodiment of the utility model.
[0013] Figure 2 It is an exploded view of an existing lamp base in the background art of the utility model. Specific Embodiments
[0014] As Figure 1 shown, a waterproof lamp base includes a base 1. The base 1 is provided with a lamp socket 2 electrically connected to a bulb. The lamp socket 2 is electrically connected to a wire 3 extending outside the base. A cylindrical lower lamp cover 4 is provided around the lamp socket 2 above the base 1. The lower lamp cover 4 is detachably provided with a semi-elliptical upper lamp cover 5. The lower lamp cover 4 and the upper lamp cover 5 are closed to form an accommodation cavity 6 for accommodating the bulb and the lamp socket 2. An inner connecting wall 7 is provided around the opening on the inner side above the lower lamp cover 4. The outer end face of the connecting wall 7 is provided with an external thread. The inner wall below the upper lamp cover 5 is provided with an internal thread at the opening. The internal thread is in threaded cooperation with the external thread. The upper lamp cover 5 is fixedly provided with a first waterproof rubber gasket 8 along the lower opening. A limiting ring 9 is provided around the inner wall of the lower opening of the upper lamp cover 5. A second waterproof rubber pad 10 is provided at one end of the limiting ring 9 facing the lower lamp cover 4. When the upper lamp cover 5 and the lower lamp cover 4 are closed until the first waterproof rubber gasket 8 abuts against the upper opening of the lower lamp cover 4, the second waterproof rubber pad 10 abuts against one end above the connecting wall 7. The wire 11 is sealed with waterproof glue at the place where the wire 11 extends out of the base 1.
[0015] The first waterproof rubber gasket 8 serves as the first waterproof seal, and the connecting wall 7 serves as the second waterproof seal. There is a height difference formed at the junction of the upper lamp cover 5 and the lower lamp cover 4 above the connecting wall 7, so that the water flowing to the junction of the openings of the upper lamp cover 5 and the lower lamp cover 4 cannot penetrate into the accommodation cavity 6. The second waterproof rubber gasket 10 serves as the third waterproof seal. The wire 3 extending out of the base 1 is sealed with waterproof sealant. The waterproof sealant can fill the gap according to the shape of the wire 3, achieving a better sealing effect. With multiple seals, the accommodation cavity 6 is completely sealed and isolated from water, avoiding short circuits caused by water ingress.
