Description

Technical Field

[0001] This utility model relates to the technical field of bulb lamps, specifically to a waterproof structure for a bulb lamp holder. Background Technology

[0002] A bulb lamp is a new type of energy-saving lighting fixture that replaces traditional incandescent bulbs. A bulb consists of seven parts. The top part is a glass cover that is clipped onto a base. The base has a hole that connects to a heat sink, which in turn connects to a heat dissipation unit. The lamp holder connects to the driver and the internal LED chip. The lamp holder is the electronic component that fixes the bulb's position and connects the lamp contacts to the power supply. For many bulb lamps used outdoors or in humid environments, the lamp holder structure needs to have a certain degree of waterproofing.

[0003] A waterproof bulb holder structure disclosed in Chinese Patent Publication No. CN222168888U includes a bulb holder base and a bulb holder connector. The bulb holder base on the outer side of the bulb holder connector has several fixing holes at equal intervals. A limiting plate is fixed to one end of the bulb holder connector away from the bulb holder base. A fixing sleeve is threaded onto the bulb holder connector between the limiting plate and the bulb holder base. A sealing cover is fixed to the outer surface of the fixing sleeve.

[0004] In the above solution, by screwing the bulb lamp into the bulb lamp holder tube and then screwing the sealing cover into contact with the upper surface of the bulb lamp, the bulb lamp holder tube and the bulb lamp interface are sealed. This results in the following disadvantage: the threaded connection between the fixing sleeve and the bulb lamp holder tube lacks waterproof treatment, which allows water to seep in along the thread gaps, resulting in poor waterproofing. Utility Model Content

[0005] The purpose of this invention is to provide a waterproof structure for a bulb lamp holder, in order to solve the problem that the threaded connection between the fixing sleeve and the bulb lamp holder tube lacks waterproof treatment, which allows water to seep in along the thread gaps and results in poor waterproofing.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a waterproof structure for a bulb lamp holder, comprising a bulb lamp holder connector, the bulb lamp holder connector being fixed to the bottom surface of a bulb lamp holder base, the outer wall of the bulb lamp holder connector being provided with an external thread, a limit ring being fixed to the outer wall of the bulb lamp holder connector, a sleeve being rotatably provided on the outer wall of the bulb lamp holder connector, the inner wall of the sleeve being provided with an internal thread, the internal thread being threadedly connected to the external thread, a sealing cover being fixed to the outer wall of the sleeve, a pressure ring being slidably fitted on the outer wall of the bulb lamp holder connector, a sealing gasket being fixed to the bottom surface of the pressure ring, two snap-fit ​​holes being opened at the top of the sleeve, and two elastic snap-fit ​​blocks being fixed to the bottom surface of the pressure ring, the two elastic snap-fit ​​blocks being detachably snapped into the two snap-fit ​​holes respectively.

[0007] Preferably, a sealing ring is fixed at the bottom end of the sleeve.

[0008] Preferably, the outer wall of the bulb lamp holder connector is provided with sliding grooves on the left and right sides, and the inner wall of the pressure ring is fixed with sliders on the left and right sides, and the two sliders are respectively slidably arranged in the two sliding grooves.

[0009] Preferably, the outer wall of the sleeve is detachably fitted with two arc-shaped clamps, and the bottom surface of each of the two arc-shaped clamps is fixed with a waterproof cover.

[0010] Preferably, the right side of the arc-shaped clamp on the left side has two mounting slots, the top surface of the arc-shaped clamp on the left side has two fixing holes, and the left side of the arc-shaped clamp on the right side has two mounting blocks. The two mounting blocks are detachably installed in the two mounting slots, and the top surface of each of the two mounting blocks has a fixing slot. Insertion shafts are slidably inserted into the two fixing slots, and the two insertion shafts are slidably inserted into the two fixing holes. Springs are fixed between the bottom ends of the two insertion shafts and the two fixing slots.

[0011] Preferably, the inner walls of both of the arc-shaped clamps are fixed with sealing gaskets.

[0012] Compared with existing technologies, the waterproof structure of a bulb holder that adopts the above technical solution has the following beneficial effects: 1. In use, through the synergistic action of the bulb lamp holder connector, bulb lamp holder base, external thread, limit ring, sleeve, internal thread, sealing cover, pressure ring, sealing gasket, snap-fit ​​hole and elastic snap-fit ​​block, the sealing of the bulb lamp holder connector and the bulb lamp interface is achieved, and water can be prevented from seeping in from the thread gap, which further improves the waterproof effect. Second, during use, this tight fit allows the sleeve to be more securely screwed onto the bulb lamp holder connector. Simultaneously, it works in conjunction with the sealing gasket to form multiple lines of defense. The sealing ring effectively prevents moisture from seeping in from the contact surface between the sleeve and the limiting ring, further enhancing the reliability of the entire waterproof structure. The slider moves within the groove, limiting the pressure ring and ensuring that the elastic snap-fit ​​block can be accurately and detachably snapped into the snap-fit ​​hole without frequent adjustments, improving installation efficiency and accuracy. The waterproof cover prevents rainwater from directly hitting the bulb lamp holder base and bulb lamp holder connector, providing a better waterproofing effect. Third, this design facilitates disassembly and assembly by staff, making maintenance and replacement easy without the need for additional tools, thus improving usability. The sealing gasket fills the tiny gaps between the curved clamp and the sleeve, effectively preventing moisture from seeping in through these gaps, further enhancing the overall waterproof performance of the structure.

[0018] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0019] like Figures 1-3As shown, a waterproof structure for a bulb lamp holder includes a bulb lamp holder connector 1, which is fixed to the bottom surface of a bulb lamp holder base 2. The outer wall of the bulb lamp holder connector 1 is provided with an external thread 3. A limit ring 4 is fixed to the outer wall of the bulb lamp holder connector 1. A sleeve 5 is rotatably provided on the outer wall of the bulb lamp holder connector 1. The inner wall of the sleeve 5 is provided with an internal thread 6, which is threadedly connected to the external thread 3. A sealing cover 7 is fixed to the outer wall of the sleeve 5. A pressure ring 8 is slidably fitted on the outer wall of the bulb lamp holder connector 1. A sealing gasket 9 is fixed to the bottom surface of the pressure ring 8. Two snap-fit ​​holes 10 are opened at the top of the sleeve 5. Two elastic snap-fit ​​blocks 11 are fixed to the bottom surface of the pressure ring 8. The two elastic snap-fit ​​blocks 11 are detachably snapped into the two snap-fit ​​holes 10.

[0020] During use, the operator first precisely and securely screws the bulb into the bulb holder connector 1 and fixes it in place. Then, the sleeve 5 is rotated. Because the internal thread 6 on the inner wall of the sleeve 5 is tightly threaded to the external thread 3 on the outer wall of the bulb holder connector 1, the sleeve 5 drives the sealing cover 7 fixed on the outer wall to rotate and move downwards synchronously during rotation. When the sealing cover 7 moves down to tightly abut against the outer surface of the bulb, the bottom surface of the sleeve 5 just abuts against the top surface of the limiting ring 4. At this time, a preliminary seal is formed between the bulb holder connector 1 and the bulb interface, effectively preventing moisture from entering. This design not only prevents the bulb holder body from getting damp and rusting, but also extends the service life of the bulb holder body.

[0021] Next, the staff slides the pressure ring 8 down along the outer wall of the bulb lamp holder connector 1. During the sliding process, the two elastic snap-fit ​​blocks 11 on the bottom surface of the pressure ring 8 will be detachably snapped into the two snap-fit ​​holes 10 opened at the top of the sleeve 5, thereby firmly connecting and fixing the pressure ring 8 to the sleeve 5. At this time, the sealing gasket 9 fixed on the bottom surface of the pressure ring 8 will be squeezed, and its inner wall will be tightly pressed against the outer wall of the bulb lamp holder connector 1, further preventing water from seeping in along the thread gap, achieving a double seal at the bulb lamp holder connector 1 and the bulb lamp interface, and improving the waterproof effect.

[0022] Through the coordinated action of bulb lamp holder connector 1, bulb lamp holder base 2, external thread 3, limiting ring 4, sleeve 5, internal thread 6, sealing cover 7, pressure ring 8, sealing gasket 9, snap-fit ​​hole 10 and elastic snap-fit ​​block 11, the bulb lamp holder connector 1 and the bulb lamp interface are sealed, and water is prevented from seeping in through the thread gap, which further improves the waterproof effect.

[0023] like Figures 1-3 As shown, a sealing ring 12 is fixed at the bottom end of the sleeve 5.

[0024] During use, when the staff connects the sleeve 5 to the bulb lamp holder connector 1 by thread, the sealing ring 12 fixed at the bottom of the sleeve 5 will tightly abut against the top surface of the limiting ring 4. This tight abutment allows the sleeve 5 to be screwed more securely onto the bulb lamp holder connector 1. At the same time, it works in conjunction with the sealing gasket 9 to form multiple sealing defenses. The sealing ring 12 can effectively prevent moisture from seeping in from the contact surface between the sleeve 5 and the limiting ring 4, further enhancing the reliability of the entire waterproof structure.

[0025] like Figures 1-4 As shown, the outer wall of the bulb lamp holder connector 1 has grooves 13 on both the left and right sides. The inner wall of the pressure ring 8 has sliders 14 fixed on both the left and right sides. The two sliders 14 are slidably set in the two grooves 13 respectively. The outer wall of the sleeve 5 has two arc-shaped clamps 15 detachably installed. The bottom surface of the two arc-shaped clamps 15 is fixed with a waterproof cover 16.

[0026] During use, when the operator slides the pressure ring 8 onto the outer wall of the bulb holder connector 1, the slider 14 slides within the groove 13, limiting the pressure ring 8 and ensuring that the elastic snap-fit ​​block 11 can be accurately and detachably snapped into the snap-fit ​​hole 10 without frequent adjustments, thus improving installation efficiency and accuracy. When the bulb holder base 2 and bulb holder connector 1 are used in a relatively open outdoor environment, the two arc-shaped clamps 15 and two waterproof covers 16 are assembled onto the sleeve 5. The waterproof covers 16 prevent rainwater from directly hitting the bulb holder base 2 and bulb holder connector 1, providing better waterproofing. They also prevent damage to the bulb from falling debris, offering better protection for the bulb. The combined design of the arc-shaped clamps 15 and waterproof covers 16 provides effective protection for the bulb holder when used outdoors.

[0027] like Figure 1 , Figure 2 and Figure 4 As shown, the right side of the left arc-shaped clamping plate 15 has two mounting slots 17, the top surface of the left arc-shaped clamping plate 15 has two fixing holes 18, and the left side of the right arc-shaped clamping plate 15 has two mounting blocks 19 fixed. The two mounting blocks 19 are detachably installed in the two mounting slots 17. The top surface of each mounting block 19 has a fixing slot 20. Insertion shafts 21 are slidably inserted into the two fixing slots 20. The two insertion shafts 21 are slidably inserted into the two fixing holes 18. Springs 22 are fixed between the bottom end of each insertion shaft 21 and the two fixing slots 20. Sealing gaskets 23 are fixed to the inner walls of both arc-shaped clamping plates 15.

[0028] In this device, when assembly is required, the operator first presses the two insert shafts 21 into the fixed groove 20. At this time, the spring 22 is in a compressed state. Then, the two arc-shaped clamps 15 are installed on the outer wall of the sleeve 5 and pressed tightly together. The mounting block 19 fixed on the left side of the right arc-shaped clamp 15 is accurately inserted into the mounting groove 17 opened on the right side of the left arc-shaped clamp 15. When the mounting block 19 is fully inserted, the compressed spring 22 releases its elastic potential energy, automatically resetting the insert shafts 21 and allowing them to slide into the fixed hole 18, thus completing the assembly of the two arc-shaped clamps 15 and the two waterproof covers 16. Conversely, when disassembly is required, the insert shafts 21 are simply pressed to disengage them from the fixed hole 18, allowing the two arc-shaped clamps 15 to be separated. This design facilitates disassembly and assembly operations, makes maintenance or replacement convenient, and requires no additional tools, thus improving ease of use. When the two arc-shaped clamps 15 are installed on the sleeve 5, the sealing gasket 23 fixed on the inner wall of the arc-shaped clamps 15 will fit tightly against the outer wall of the sleeve 5. The sealing gasket 23 can fill the tiny gaps between the arc-shaped clamps 15 and the sleeve 5, effectively preventing moisture from seeping in from these gaps, and further enhancing the waterproof performance of the entire structure.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
