Description

Technical Field

[0001] This utility model relates to a lamp structure with a quick-change lamp head, belonging to the field of lamp technology. Background Technology

[0002] Existing optical instruments typically use flexible spotlights for illumination. A flexible spotlight generally consists of a metal flexible tube, a lamp head and a lamp holder at both ends of the metal flexible tube. The metal flexible tube and the lamp holder are detachable structures, but the flexible tube is connected to the lamp head as a whole, making it difficult to replace when the lamp head burns out or malfunctions. At the same time, it brings inconvenience to packaging and transportation.

[0003] Therefore, the research objective of this utility model is to provide a lamp structure that allows for quick lamp head replacement. Utility Model Content

[0004] To address the shortcomings of the aforementioned technologies, this utility model provides a lamp fixture structure with a quick-change lamp head. The lamp head can be easily detached from the metal flexible tube and easily reattached to the metal flexible tube, thus facilitating lamp head replacement, packaging, and transportation.

[0005] To solve the problems of the existing technology, the technical solution adopted by this utility model is as follows:

[0006] A lamp holder structure with quick-change lamp head includes a flexible metal tube and a lamp head. One end of the flexible metal tube is fixedly connected to a pipe connector, and the other end of the pipe connector is threadedly connected to a socket. The socket is a hollow structure with a nut fitted on its outer side. One end of the lamp head is fixedly connected to a first threaded connector, which is also a hollow structure with a plug matching the socket at its inner bottom. After the socket is inserted into the first threaded connector, it is electrically connected to the plug. The nut is tightened onto the first threaded connector to achieve a fixed connection between the flexible metal tube and the lamp head.

[0007] Furthermore, a lamp source assembly is provided on the inner side of the end of the lamp head away from the first threaded connector. The lamp source assembly is electrically connected to the plug. A lamp cover is connected to the end of the lamp head away from the first threaded connector. A lens matching the lamp source assembly is provided on the inner side of the lamp cover.

[0008] Furthermore, the lens is configured as a single-layer lens or a multi-layer lens; the diameter of the lamp cover at the end near the lamp head is larger than the diameter at the other end.

[0009] Furthermore, a positive and negative connector is fixedly connected to one end of the socket near the pipe joint, and a nut stop is fixedly provided on the outside, with the nut located between the nut stop and the lamp holder.

[0010] Furthermore, a second threaded connector is fixed to the end of the metal flexible tube away from the lamp holder.

[0011] The beneficial effects of this utility model are: through the cooperation of the first threaded connector and the nut, the lamp holder can be easily removed from the metal hose and can be easily reinstalled on the metal hose, which brings convenience to the replacement, packaging and transportation of the lamp holder.

Detailed Implementation

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the following description is provided in conjunction with the appendix. Figure 1-8 Further analysis of this utility model is then conducted.

[0022] like Figure 1-8As shown, a lamp holder structure with quick-change lamp head includes a metal flexible tube 1 and a lamp head 2. One end of the metal flexible tube 1 is fixedly connected to a pipe connector 3, and the other end of the pipe connector 3 is threadedly connected to a socket 4. The socket 4 is a hollow structure with a nut 5 fitted on its outer side. One end of the lamp head 2 is fixedly connected to a first threaded connector 6. The first threaded connector 6 is a hollow structure with a plug 7 matching the socket 4 at its inner bottom. After the socket 4 is inserted into the first threaded connector 6, it is electrically connected to the plug 7. The nut 5 is tightened on the first threaded connector 6 to achieve a fixed connection between the metal flexible tube 1 and the lamp head 2.

[0023] In this embodiment, preferably, a lamp source assembly 8 is provided on the inner side of the end of the lamp head 2 away from the first threaded connector 6. The lamp source assembly 8 is electrically connected to the plug 7 via a wire. A lamp cover 9 is connected to the end of the lamp head 2 away from the first threaded connector 6. A lens 10 matching the lamp source assembly 8 is provided on the inner side of the lamp cover 9.

[0024] In this embodiment, preferably, the lens 10 is configured as a single-layer lens or a multi-layer lens; the diameter of the lamp cover 9 at one end near the lamp head 2 is larger than the diameter of the other end.

[0025] In this embodiment, preferably, a positive and negative electrode connector 11 is fixedly connected to one end of the socket 4 near the pipe connector. The positive and negative electrode connector 11 is electrically connected to the battery or power connector in the lamp holder through the wire in the metal flexible tube 1 to supply power to the lamp source assembly 8. A nut stop 12 is fixedly provided on the outside, and the nut 5 is located between the nut stop 12 and the lamp holder 2.
