Description

Technical Field

[0001] The utility model relates to the technical field of lamps, and more specifically to a double-layer waterproof Christmas lamp. Background Art

[0002] Christmas lights, also known as Christmas lights, are traditional lamps used to decorate indoor and outdoor environments during the Western Christmas season. They not only add to the festive atmosphere, but also carry rich cultural and religious symbolic meanings.

[0003] In the prior art, the structure of Christmas lights includes a lamp housing, a lamp holder connected to a power source is installed on the lamp housing, an inner bulb is installed on the lamp holder, and an outer bulb is installed on the lamp housing to wrap the inner bulb. Usually, waterproof treatment is done between the outer bulb and the outer housing. However, under the external force of some uncontrolled silicon, the lamp housing is deformed, resulting in damage to the waterproof structure, and its waterproof performance is greatly reduced. Or the outer bulb is broken due to external force, which will cause water to enter the lamp housing from the outside. Since the inner bulb has no waterproof function, it will cause a short circuit in the circuit, making the entire Christmas light scrapped, which is also unsafe. Utility Model Content

[0007] Waterproof ring, installed at the bottom of the card slot;

[0008] The inner bulb is mounted on the top of the lamp holder and is threadedly connected to the threaded hole;

[0009] The waterproof cover is installed on the bulb, and an annular card plate is installed at the bottom to fit with the card slot. After the inner bulb is screwed into the threaded hole, the bottom of the card plate is tightly pressed against the waterproof ring.

[0010] Preferably, a cover is mounted on the waterproof cover and is sleeved on the top of the lamp holder.

[0011] Preferably, the cover is spaced outside the outer circle of the card plate, and a sleeve cavity is provided inside the cover to fit with the top of the lamp holder.

[0012] Preferably, the portion of the lamp holder that cooperates with the sleeve cavity is a mounting portion, the mounting portion is cylindrical, and the sleeve cavity is also cylindrical.

[0013] Preferably, an annular reinforcement ring is sleeved on the bottom of the slot, and the reinforcement ring is tightly matched with the waterproof ring.

[0014] Preferably, the inner wall of the sleeve cavity is smooth or provided with threads.

[0015] Preferably, the waterproof ring is made of elastic material.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] When the inner bulb is installed by screwing, the card plate on the waterproof cover is embedded in the card slot and fits tightly with the waterproof ring. The structure is simple and the installation is convenient, and the waterproof treatment between the inner bulb and the lamp holder is realized. In this way, when the first layer of waterproofing between the outer bulb and the shell is damaged, the second layer of waterproofing structure between the waterproof cover and the lamp holder can block water from entering the inner bulb, prevent the short circuit of the entire circuit, and ensure product safety.

[0023] 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.

[0024] refer to Figure 1-3A double-layer waterproof Christmas light comprises a shell 1, an outer bulb 2 is mounted on the top of the shell 1, a waterproof structure is arranged between the outer bulb 2 and the shell 1, and further comprises: a lamp holder 3 is mounted inside the shell 1, a threaded hole for connecting a circuit and an annular groove 32 coaxially arranged with the threaded hole are opened on the top, and the inner diameter of the groove 32 is larger than the inner diameter of the threaded hole; a waterproof ring 4 is mounted on the bottom of the groove 32; an inner bulb 5 is mounted on the top of the lamp holder 3 and is threadedly connected with the threaded hole; a waterproof cover 6 is mounted on the bulb, and an annular clamping plate 61 embedded with the clamping plate 32 is mounted on the bottom, and after the inner bulb 5 is screwed into the threaded hole, the bottom of the clamping plate 61 is sealed and pressed tightly against the waterproof ring 4.

[0025] It can be understood that the waterproof structure set between the outer bulb 2 and the outer shell 1 is a prior art, and will not be described in detail here. This is the first layer of waterproof structure. The inner bulb 5 is connected to the lamp holder 3 by threads, and needs to be rotated during installation, so the clamping plate 61 and the clamping slot 32 are both set in a ring shape, so that when the inner bulb 5 drives the clamping plate 61 to rotate in the clamping slot 32, the threaded rotation installation of the inner bulb 5 is not affected. The installation of the inner bulb 5 is a downward movement process, and the clamping plate 61 moves downward and then abuts against the waterproof ring 4, completing the sealing installation and forming the second layer of waterproof structure. The waterproof ring 4 is made of elastic material, such as: silicone, nitrile rubber, chloroprene rubber, fluororubber, etc. With this arrangement, even if the first layer of waterproof structure between the outer bulb 2 and the outer shell 1 is damaged, the second waterproof structure between the inner bulb 5 and the lamp holder 3 can serve as a waterproof barrier to ensure the safety of the circuit.

[0026] In some embodiments, the waterproof cover 6 is provided with a cover 62 which is sleeved on the top of the lamp holder 3. Furthermore, the cover 62 is arranged at intervals outside the outer circle of the card plate 61, and a sleeve cavity 621 which is sleeved with the top of the lamp holder 3 is provided inside the cover 62. It can be understood that the card plate 61 is located inside the sleeve cavity 621 of the cover 62, and the cover 62 can surround the card plate 61 and the card slot 32. The inner wall of the sleeve cavity 621 can be smooth and slidably sleeved on the top of the lamp holder 3. Threaded connection can also be used inside the sleeve cavity 621 and the outer wall of the lamp holder 3 to further improve the waterproof performance. Furthermore, the part of the lamp holder 3 that cooperates with the sleeve cavity 621 is the mounting portion 31, the mounting portion 31 is cylindrical, and the sleeve cavity 621 is also cylindrical. Similarly, this structure is also for the threaded rotation installation of the inner bulb 5.

[0027] In some embodiments, the bottom of the card slot 32 is provided with an annular reinforcement ring 7, and the reinforcement ring 7 is closely matched with the waterproof ring 4. It can be understood that the card slot 32 is generally made of hard plastic, and the waterproof ring 4 is a soft material, and the rigidity and softness are not well complementary. Here, the reinforcement ring 7 is made of soft material, such as silicone, rubber, etc. The combination of two layers of soft materials can complement each other, improve the overall waterproof continuity and reliability, and reduce the risk of leakage caused by the performance limitations of a single material.

[0028] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
