[0002] Existing chain lights, such as Patent Document No. CN116538477A (hereinafter referred to as Document 1), disclose a magnetic chain light that can be spliced and assembled, and its use method. This utilizes a magnetic splicing and rotating structure to achieve both the splicing and angle adjustment of the lamp units. However, the solution in Document 1 is complex in its waterproofing structure, typically requiring multiple components (such as a back cover, silicone ring, wires, and waterproof connectors) to achieve waterproofing. This complex waterproofing structure results in cumbersome assembly, high material costs, low production efficiency, and inconvenience during maintenance and repair.

[0003] Therefore, in view of the problems of complex waterproof structure, low assembly efficiency and inconvenient maintenance in the existing technology such as Document 1, the industry urgently needs a chain light body and chain light that simplifies the waterproof structure, improves assembly efficiency, reduces production costs, and facilitates subsequent maintenance and replacement. Utility Model Content

[0004] The purpose of the present invention is to provide a lamp body for a chain lamp and a chain lamp to address the deficiencies in the prior art, aiming to simplify the waterproof structure, improve assembly efficiency, reduce production costs, and facilitate subsequent maintenance and replacement.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions: A lamp body for a chain lamp, comprising:

[0006] The main body is provided with a circuit board and a terminal block electrically connected to the circuit board;

[0007] a raised portion, formed integrally with the main body, with one end away from the main body being open;

[0008] a waterproof seal disposed within the raised portion; and

[0009] The waterproof wire mounting block is integrally injection molded with a terminal block, which is pluggable into the terminal block. The waterproof wire mounting block is tightly fitted or threaded into the raised portion and sealed to the opening via the waterproof seal. Specifically, the light is emitted in a direction from the main body away from the raised portion.

[0010] As a further solution of the present invention: the side wall of the main body is provided with an air hole and a breathing valve which is encapsulated in the air hole and is waterproof and breathable.

[0011] As a further solution of the present invention, the breathing valve adopts a one-way breathable membrane structure, and the waterproof seal is a waterproof silicone pad. Specifically, the waterproof silicone pad has an opening in the middle, allowing the pins of the terminal to pass through the waterproof silicone pad and be inserted into the terminal block.

[0012] As a further solution of the present invention: a cross section of the lamp body is a "convex"-shaped structure, and the bottom and top of the "convex"-shaped structure correspond to the main body and the raised portion respectively.

[0013] As a further solution of the present invention: a limit platform is provided inside the raised portion and is placed by the waterproof seal. A mounting platform is also provided which extends toward the main body and is placed and installed by the circuit board. A accommodating space is formed between the mounting platform and the limit platform and is filled with the wiring seat.

[0014] As a further solution of the present invention: both outer walls of the main body and one side of the air vent are adjacent to each other and are provided with arc surface structures.

[0015] As a further solution of the present invention: wire threading openings are respectively provided on both sides of the raised portion, and two wire bodies are led out of the wiring terminal. One end of the two wire bodies is away from the wiring terminal and extends from a side wall of the waterproof wire mounting block and passes through one wire threading opening, and the other end of the two wire bodies is away from the wiring terminal and extends from the other side wall of the waterproof wire mounting block and passes through the other wire threading opening.

[0016] The present invention also provides another technical solution: a chain light, comprising at least two lamp bodies for chain lights as described in any one of the above items, wherein the main body of the lamp body is provided with connecting surfaces distributed on both sides of the protrusion on one side of the protrusion;

[0017] The chain light further comprises a connecting member, one end of which is hinged to a connecting surface of the lamp body, and the other end of which is hinged to a connecting surface of the other lamp body.

[0018] As a further solution of the present invention: the connecting member is a connecting piece structure, and each lamp body can be rotated at least 90 degrees relative to the connecting member, so that any two adjacent lamp bodies can be aligned, close together and folded.

[0019] Working principle: The external power supply is connected to the terminal blocks of the waterproof wire mounting block through the wire body. The terminal blocks can be plugged into the terminal block to achieve electrical connection with the circuit board. The circuit board distributes electrical energy to the LED lamp beads, driving them to emit light. The waterproof wire mounting block fits tightly with the raised part, and the waterproof seal is used to effectively seal the opening to prevent moisture and dust from entering. The opening design of the waterproof silicone pad allows the pins of the terminal blocks to pass through without affecting the sealing performance. A breathing valve is provided in the air vent on the side wall of the main body, and a one-way breathable membrane structure is adopted to allow internal hot air to be discharged and prevent external liquid water from entering. The outer wall design of the arc surface structure increases the heat dissipation area and improves the heat dissipation effect. Through the hinged design of the connector, the angle between the lamp bodies can be flexibly adjusted to adapt to different installation environments. When transportation or storage is required, the lamp body can be rotated and folded to reduce space occupation.

[0020] Beneficial effects of the utility model:

[0021] Improve production efficiency and reduce costs. The number of parts is reduced, the assembly process is simplified, and the complicated wire bonding process is avoided, which improves production efficiency and reduces material and labor costs.

[0023] Ensure waterproof performance. The close fit between the waterproof wire installation block and the raised part, as well as the effective sealing of the waterproof seal, ensure the waterproof performance of the product and meet the use requirements in outdoor environments.

[0024] The chain light body provided by this utility model successfully solves the technical problems in the prior art by simplifying the waterproof structure and optimizing the connection method, and has significant practical value and market competitiveness.

[0025] 1. The waterproof cable mounting block and terminal blocks are integrally injection-molded, and the terminal blocks are pluggable into the terminal block. This design reduces the number of parts, eliminates the traditional wire soldering process, simplifies the assembly process, and improves production efficiency. The pluggable design facilitates connection and removal of the waterproof cable mounting block and terminal block, facilitating future maintenance and replacement.

[0054] To this end, the embodiments of the present application provide a lamp body for a chain lamp and a chain lamp, which aim to simplify the waterproof structure, improve assembly efficiency, reduce production costs, and facilitate subsequent maintenance and replacement.

[0055] A lamp body for a chain lamp, comprising:

[0056] The main body 1 is provided with a circuit board 11 and a terminal block 12 electrically connected to the circuit board 11;

[0057] The raised portion 2 is integrally formed with the main portion 1 and has an open end away from the main portion 1;
