[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1 In this embodiment, a waterproof sealing structure of a light guide tube LED lamp holder is used to improve the sealing effect between the lamp holder body 1 and the light guide tube 2.

[0029] Specifically, it includes a lamp holder body 1, a light guide tube 2 and a sealing component 3; the lamp holder body 1 and the light guide tube 2 are connected via the sealing component 3, so as to achieve a sealing effect between the lamp holder body 1 and the light guide tube 2; a connection port for inserting the light guide tube 2 is opened inside the lamp holder body 1, so as to make the light guide tube 2 and the lamp holder body 1 electrically connected.

[0030] During actual use, the lamp holder body 1 and the light guide tube 2 are connected by the sealing component 3 to ensure a stable connection between the lamp holder body 1 and the light guide tube 2, while improving the sealing effect between the light guide tube 2 and the lamp holder body 1.

[0031] During actual setting, the sealing component 3 effectively connects the lamp holder body 1 and the light guide tube 2, ensuring the sealing effect therebetween, preventing the interior of the lamp from being affected by external moisture, dust, etc., thereby extending the service life of the lamp. Moreover, the sealing component 3 not only achieves the sealing effect, but also plays a connecting role, ensuring a firm connection between the lamp holder body 1 and the light guide tube 2, reducing the possibility of failure and damage caused by looseness. In addition, a connection port for inserting the light guide tube 2 is opened inside the lamp holder body 1, thereby achieving an electrical connection between the light guide tube 2 and the lamp holder body 1, thereby ensuring the normal operation of the lamp.

[0032] It can be understood that the design of connecting the sealing component 3 makes it easier to disassemble and replace the components inside the lamp, improving the convenience of maintenance. In addition, the connection method of the sealing component 3 improves the safety of the lamp and reduces safety hazards such as leakage and short circuit.

[0033] See also Figure 2-3 In order to facilitate the connection between the light guide tube 2 and the lamp holder body 1 and increase the sealing effect between the two, the sealing assembly 3 in this embodiment includes a rubber pad 301, a locking piece 302, a sleeve 303 and a plurality of barbed pieces 304; the rubber pad 301 is sleeved on the outside of the light guide tube 2, and the rubber pad 301 is attached to the inner wall of the connecting port, and the locking piece 302 is sleeved on the outside of the light guide tube 2 and is attached to the rubber pad 301.

[0034] The locking member 302 includes an outer ring 3021 and an inner ring 3022, and the outer ring 3021 and the inner ring 3022 are integrally formed. The sleeve 303 is sleeved on the outside of the light guide tube 2, and a plurality of barbs 304 are distributed in a ring-shaped arrangement on the inner side of the sleeve 303, and one end of the barbs 304 away from the sleeve 303 is attached to the outside of the light guide tube 2; a first protrusion 305 is provided on the outer peripheral surface of the sleeve 303, and corresponding to the first protrusion 305, a groove for the first protrusion 305 to be embedded is opened inside the connecting port.

[0035] In actual use, the rubber pad 301, the locking piece 302 and the sleeve 303 are sequentially installed into the connection port inside the lamp holder body 1, and then the light guide tube 2 is sequentially inserted from the inside of the sleeve 303, the locking piece 302 and the rubber pad 301, so that one end of the light guide tube 2 is connected to the lamp holder body 1, and the sleeve 303 is pressed down so that the first protrusion 305 on the outer side of the sleeve 303 extends into the groove inside the connection port, and at the same time, the inner ring 302 on the locking piece 302 is used to lock the light guide tube 2. 022, that is, when the sleeve 303 moves toward the lamp holder body 1, the barb piece 304 fits with the inner side of the inner ring 3022, and at the same time, the abutment of the inner ring 3022 makes one end of the barb piece 304 move toward the direction of the light guide tube 2. When the first protrusion 305 on the outer side of the sleeve 303 is embedded in the corresponding groove, at this time, several barbs 304 are all fitted on the outer side of the light guide tube 2, which can effectively fix the light guide tube 2 inside the connecting port.

[0036] It should be noted that the sleeve 303 pushes the locking member 302 back during the movement, and the rubber pad 301 is compressed by the locking member 302 , and the rubber pad 301 has a certain elasticity.

[0037] Furthermore, in order to ensure that the barb piece 304 can effectively clamp the light guide tube 2 inside the sleeve 303 after contacting the outer peripheral surface of the light guide tube 2, the barb piece 304 in this embodiment is preferably inclined toward the lamp holder body 1 at one end away from the sleeve 303.

[0038] In actual configuration, when the barbed piece 304 contacts the light guide tube 2 , the three are arranged in a Z-shape, which can effectively improve the stability of the connection between the three.

[0039] Furthermore, in order to ensure the stability of the rubber pad 301 , the outer ring 3021 and the sleeve 303 after installation, the outer diameters of the rubber pad 301 , the outer ring 3021 and the sleeve 303 in this embodiment are all adapted to the inner diameter of the connection port.

[0040] In addition, when the sleeve 303 moves toward the locking member 302, the distance between the two relative barbs 304 can be effectively reduced, so that the barbs 304 can effectively fit with the outer periphery of the light guide 2. The inner side of the inner ring 3022 in this embodiment and one end close to the barbs 304 are arranged in an inclined surface.

[0041] During actual use, the sleeve 303 moves toward the locking piece 302, and the barb 304 contacts the inclined surface on the inner side of the inner ring 3022, that is, during the extension of the sleeve 303, the inner ring 3022 pushes one end of the barb 304 to move toward the direction of the light guide tube 2, so that the barb 304 effectively fits the outer side of the light guide tube 2, and when the first protrusion 305 on the outer side of the sleeve 303 extends to the corresponding groove, the sleeve 303 is fixed in the connecting port inside the lamp holder body 1, and the light guide tube 2 is fixed inside the sleeve 303.

[0042] It should be noted that the barb piece 304 is an elastic metal piece, and a certain distance is reserved between the sleeve 303 and the light guide tube 2 so that a certain rebound gap is reserved between the barb piece 304 and the sleeve 303 .

[0043] In actual configuration, using an elastic metal sheet as the barb sheet 304 can provide sufficient elasticity and flexibility to adapt to light guide tubes 2 of different sizes and shapes, thereby ensuring the stability and durability of the snap-in effect.

[0044] In detail, in order to ensure that during the extension process of the sleeve 303, one end of the barb piece 304 pushed inward by the inner ring 3022 moves toward the direction of the light guide tube 2, the inner ring 3022 in this embodiment is attached to the inner wall of the sleeve 303, and one end of the inner ring 3022 extends to the rebound gap between the barb piece 304 and the sleeve 303.

[0045] In addition, in order to facilitate the removal of the light guide tube 2 and the lamp holder body 1, the sealing assembly 3 in this example also includes a loosening structure, which is arranged inside the sleeve 303, and the loosening structure includes a loosening cap 306 and a second protrusion 307; one end of the loosening cap 306 extends to the inside of the sleeve 303, and the second protrusion 307 is integrally formed on the outside of the loosening cap 306, and corresponding to the second protrusion 307, a second groove for the second protrusion 307 to be embedded is opened on the inner wall of the sleeve 303.

[0046] In addition, in order to facilitate the release cap 306 to effectively push one end of the barb piece 304 when moving, one end of the release cap 306 in this embodiment is fitted between the light guide tube 2 and the inner wall of the sleeve 303, and one end of the release cap 306 is located on the side of the barb piece 304 away from the locking piece 302.

[0047] During actual use, by pressing the release cap 306, one end of the release cap 306 extends to between the barb piece 304 and the light guide tube 2, and at the same time, the end of the barb piece 304 that is in contact with the light guide tube 2 is lifted up to leave a certain gap between the barb piece 304 and the light guide tube 2. At this time, the light guide tube 2 can be pulled out from the inside of the sleeve 303.

[0048] It should be noted that when the release cap 306 is pressed, the second protrusion 307 will move out from the inside of the second groove, and in the process of movement, it will push one end of the barb piece 304 and the locking piece 302 to move a short distance, and at the same time compress the rubber pad 301. When the light guide 2 is moved out from the inside of the sleeve 303, the release cap 306 is released. At this time, the rubber pad 301 and the barb piece 304 will rebound and push the release cap 306 at the same time, so that the second protrusion 307 on the release cap 306 is embedded in the second groove again.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
