A marquee lamp holder

Abstract

The invention particularly relates to a horse-racing lamp holder, belonging to the technical field of lighting equipment or decorative lamp, comprising a lamp holder and a locking wire cover. The inner cavity of the lamp holder is a lamp bulb accommodating cavity. The end face of the lamp holder is provided with a clamping wire groove, and the port of the lamp bulb accommodating cavity is providedwith a built-in waterproof ring structure, which is combined with the inner wall of the port to form a waterproof cover after lamp bulb installation. The bottom of the bulb accommodating cavity is provided with a copper sheet structure which is directly inserted and prevents from falling off; A positive and negative pole isolation waterproof structure is arranged on the wire clamping groove, anda plurality of water-proof cavities can be formed by locking and fitting the wire locking cover. The built-in waterproof ring is not easy to fall off and forms a sealed protective cover after being combined with the light bulb, which has outstanding waterproof performance; The clamping groove separates the positive electrode seat and the negative electrode seat in two regions, and each region is provided with multiple sealing protection to form a plurality of independent isolation chambers to form isolation protection for the positive electrode seat and the negative electrode seat; Copper sheet adopts flat type, can save copper material, reduce production cost, and through the shrapnel lock, do not fall off, installation is convenient and quick.

Description

technical field [0001] The invention belongs to the technical field of lighting equipment or decorative lamps, in particular to a marquee lamp holder. Background technique [0002] The existing marquee is one of the outdoor lights, which is mainly composed of a power cord of a certain length and a plurality of waterproof lamp holders arranged on the power cord and electrically connected to the power cord, wherein the waterproof lamp holders are spaced set on the power line. In the specific use process, a light bulb can be connected to each waterproof lamp holder, and the power cord can be hung at the place where lighting is required, so as to achieve the effect of lighting and decoration in a large area around the area. [0003] The authorized announcement number is CN201045488Y, which discloses a waterproof marquee lamp. The bottom of the lamp housing 2 is provided with a wire groove 22. The inner concave surface 221 of the wire groove 22 matches the shape of the wire. Th...

Problems solved by technology

In this solution, the waterproof treatment of the power cord is poor, and the bulb is installed in the form of a rubber ring outsourcing, which cannot prevent rainwater from leaking

[0005] The authorized announcement number is CN105006720B, which discloses a waterproof lamp holder for outdoor light strings. In this document, the waterproof treatment of the light bulb installation is also adopted. The waterproof ring is set on the outer peripheral surface of the waterproof lamp holder. This method exists The waterproof ring is not firmly fixed, and the opening of the exposed waterproof ring is upward, and the rainwater is easy to collect on the edge of the opening, and may penetrate into the lamp holder along the inner wall of the waterproof ring, causing a short circuit

[0006] To sum up, in the three published documents, there are defects in the waterproof treatment of the connection of the power cord; the conductive medium in the lamp holder uses copper pillars, which wastes resources, and the structure is likely to cause poor contact; the waterproof treatment of the bulb installation adopts an external Waterproof ring, easy to fall off, poor waterproof
