Technical Field

[0001] The utility model relates to the technical field of lighting equipment, and in particular to a convenient and detachable die-casting LED lamp housing structure. Background Art

[0002] LED lighting is mainly based on high-power white light LED single lamps. The heart of the LED is a semiconductor chip. One end of the chip is attached to a bracket, one end is the negative pole, and the other end is connected to the positive pole of the power supply, so that the entire chip is encapsulated by epoxy resin.

[0003] For example, in the patent announcement number CN209431342U, “A convenient and detachable LED lamp housing structure”, the bolt blind hole and the lamp housing are die-cast together, the fixing bolt material is made of high-hardness material with triangular-shaped teeth, and the bolt blind hole on the lamp housing is processed with a tap.

[0004] However, in the prior art, the lamp housing is fixed by screws, which are generally directly exposed on the surface of the housing. The screws are easily detached from the housing due to environmental interference, thereby causing the lamp housing to fall apart and affecting the stability of the lamp housing. Utility Model Content

[0005] The purpose of the utility model is to solve the problems existing in the prior art and to propose a convenient and detachable die-casting LED lamp housing structure.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a convenient and detachable die-cast LED lamp shell structure, including an outer shell frame, two pressing plates are arranged above the top of the outer shell frame, a connecting rod is rotatably connected between the pressing plate and the outer wall of the outer shell frame, guide grooves are provided at both ends of the outer shell frame, inner plates are provided at both ends of the outer shell frame, the inner walls of the inner plates are fixedly connected with guide rails, the guide rails are slidably connected to the guide grooves, a bayonet corresponding to the shape of the guide rail is provided on one side of the pressing plate, the inner wall of the inner plate is fixedly connected with a lamp tube interface, and the two ends of the lamp tube are connected to the power supply through the lamp tube interface.

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Example: Figure 1-4 As shown, the utility model provides a convenient and detachable die-cast LED lamp housing structure, including an outer housing frame 5, two pressing plates 1 are arranged above the top of the outer housing frame 5, a connecting rod 3 is rotatably connected between the pressing plate 1 and the outer side wall of the outer housing frame 5, a guide groove 10 is provided at both ends of the outer housing frame 5, an inner side plate 6 is provided at both ends of the outer housing frame 5, the inner side walls of the inner side plates 6 are fixedly connected with guide rails 9, the guide rails 9 are slidably connected with the guide grooves 10, a bayonet 12 corresponding to the shape of the guide rails 9 is provided on one side of the pressing plate 1, a lamp tube interface 8 is fixedly connected to the inner side wall of the inner side plate 6, and both ends of the lamp tube are connected to the power supply through the lamp tube interface 8;

[0024] The outer shell frame 5 is prepared by die-casting, wherein the inner side plates 6 are arranged at both ends of the outer shell frame 5 and connected to the power line, responsible for providing voltage and lighting to both ends of the lamp tube. When installing the lamp tube, the lamp tube is inserted obliquely into one of the lamp tube interfaces 8. When the lamp tube mouth is inserted into the lamp tube interface 8, the other end of the lamp tube is adjusted so that the other end is buckled with the lamp tube interface 8 to achieve the installation of the lamp tube. When disassembling the lamp housing, the inner side plates 6 at both ends are moved upward, and the inner side plates 6 are allowed to slide upward along the track of the guide rail 9, so that the inner side plates 6 are separated from the outer shell frame 5 and the pressing plate 1 at the same time. When the inner side plates 6 are completely separated, the bayonet 12 is no longer controlled by the limit of the guide rail 9, and the pressing plate 1 can be pressed. The pressing plate 1 is detached from the surface of the outer shell frame 5, allowing the screws on the upper surface of the outer shell frame 5 to be completely open, so that it is convenient to unscrew the screws and completely disassemble the lamp housing. When the lamp is to be assembled, first rotate the pressing plate 1 toward the outer shell frame 5 until it is close to the surface of the outer shell frame 5. Since the pressing plate 1 and the outer shell frame 5 are connected by two connecting rods 3 to form a parallelogram connection structure, the surface of the pressing plate 1 is always parallel to the surface of the outer shell frame 5, ensuring that the pressing plate 1 can completely fit the outer shell frame 5. Then, the inner side plate 6 is aligned with the pressing plate 1 and the outer shell frame 5 for insertion, and the pressing plate 1 and the outer shell frame 5 are fixed at the same time by the guide rail 9. At this time, the pressing plate 1 cannot spontaneously detach from the surface of the outer shell frame 5, and the lamp can be quickly assembled.

[0025] like Figure 3 As shown, both ends of the outer shell frame 5 are fixedly connected with outer plates 11, and the side walls of the inner plate 6 are slidably connected to the side walls of the outer plates 11. By arranging the outer plates 11 at both ends of the outer shell frame 5 and supporting the inner plate 6 with the outer plates 11, the inner plate 6 can be more stably inserted into the outer shell frame 5.

[0026] like Figure 1 As shown, the top of the inner plate 6 is fixedly connected with a bending plate 7, and the bending plate 7 is used to lock the bayonet 12, so that when the inner plate 6 is fully inserted into the lamp, the bending plate 7 ensures that the inner plate 6 will not fall off downward from the guide groove 10 and the bayonet 12.

[0027] like Figure 3 As shown, a slot is provided at the center of the top wall of the outer shell frame 5, and a reflective focusing plate 4 is installed inside the slot. The reflective focusing plate 4 is installed on the top surface of the lamp tube. The reflective focusing plate 4 can focus and reflect the lamp tube below, thereby improving the brightness of the lamp tube lighting the space below. At the same time, the reflective focusing plate 4 and the slot are installed in a single-pass direction. When the reflective focusing plate 4 needs to be cleaned, the reflective focusing plate 4 is taken out from above the slot. Therefore, the pressing plate 1 can fix the reflective focusing plate 4. Before removing the reflective focusing plate 4, the lamp needs to be disassembled as a whole to separate the pressing plate 1 from the surface of the outer shell frame 5 to ensure the stability of the overall structure.

[0028] like Figure 1As shown, adjacent sides of the pressing plate 1 are fixedly connected with magnetic plates 2, and the two magnetic plates 2 are connected to each other by magnetic attraction. By arranging the magnetic plates 2 at adjacent sections of the pressing plate 1, when the two pressing plates 1 are separated from the outer shell frame 5, it is ensured that the two pressing plates 1 are suspended above the outer shell frame 5 to prevent the pressing plates 1 from shaking at will.

[0029] like Figure 3 As shown, positioning holes are provided at both ends of the bending plate 7, and the bending plate 7 is connected to the outer shell frame 5 by screws. By providing positioning holes at both ends of the bending plate 7, the inner plate 6 and the outer shell frame 5 can be reinforced with screws after installation, thereby further improving the stability of the lamp structure.

[0030] like Figure 2 As shown, the inner wall of the outer plate 11 is paved with a sponge pad to prevent the inner plate 6 from being scratched due to long-term pressure from the two ends of the lamp tube, thereby extending the service life of the parts.

[0031] The use method and working principle of the device: When disassembling the lamp, move the inner plates 6 at both ends upward, and let the inner plates 6 slide upward along the track of the guide rail 9, so that the inner plates 6 are separated from the outer frame 5 and the pressing plate 1 at the same time. When the inner plates 6 are completely separated, the bayonet 12 is no longer controlled by the limit of the guide rail 9, and the pressing plate 1 is separated from the surface of the outer frame 5, and the reflective focusing plate 4 is taken out from the notch of the outer frame 5;

[0032] Rotate the pressing plate 1 toward the outer shell frame 5 until it is close to the surface of the outer shell frame 5. Since the pressing plate 1 and the outer shell frame 5 are connected by two connecting rods 3 to form a parallelogram connection structure, the surface of the pressing plate 1 is always parallel to the surface of the outer shell frame 5, ensuring that the pressing plate 1 can completely fit the outer shell frame 5. Then align the inner plate 6 with the pressing plate 1 and the outer shell frame 5 for insertion, and use the guide rail 9 to fix the pressing plate 1 and the outer shell frame 5 at the same time.

[0033] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
