Description

Technical Field

[0001] The present invention relates to the field of lamps, and particularly to a quick-connector lamp. Background Art

[0002] With the development of the economy and the progress of society, energy conservation has become an inevitable and social consensus. Various electrical appliances are increasingly developing towards the characteristics of energy saving, convenient use, space saving, safe and efficient, and multi-functional in one machine. The conventional wiring method uses wire connection with a terminal block, which is inconvenient to operate during installation and maintenance. Summary of the Invention

[0003] To solve the above technical problems, the present invention provides a quick-connector lamp. By means of a threaded sleeve, the expansion tube is inwardly contracted and extruded, and the wire harness located inside will be fixedly locked. The overall structure is more concise and more convenient for fixed installation and maintenance.

[0004] The technical solution adopted by the present invention to solve its technical problems is: a quick-connector lamp, including a lamp housing and a connector;

[0005] A transparent plate is provided at the front port of the lamp housing. A grounding metal column is provided on the side wall of the lamp housing, which extends from the outside of the lamp housing to the inside. A threaded hole is axially provided at the inner end of the grounding metal column. A spring is sleeved outside the grounding metal column. A bolt is fitted in the threaded hole. The two ends of the spring respectively abut against the cap portion of the bolt and the inner wall of the lamp housing;

[0006] The connector is of a cylindrical structure. The front end of the cylindrical structure is butt-connected and communicated with the inside of the lamp housing. A quick connector is provided at the rear end of the cylindrical structure; the quick connector includes a connecting pipe, an inner connecting pipe, an expansion pipe, a pressing ring and a threaded sleeve. The front end of the connecting pipe is threadedly fitted inside the rear end of the cylindrical structure. The inner connecting pipe is sleeved inside the connecting pipe. A pushing platform is provided on the periphery of the expansion pipe. The front end of the expansion pipe is sleeved inside the rear end of the inner connecting pipe. The outer wall of the rear end of the expansion pipe is set as a conical surface. The pressing ring is sleeved outside the conical surface. An end platform is provided on the inner wall of the front end of the threaded sleeve. The front end of the threaded sleeve is threadedly fitted with the rear end of the connecting pipe. The end platform abuts against the pressing ring.

[0007] The grounding metal column of this solution is provided with a spring, which can maintain a pre-tightening state of contacting with the lamp housing through the spring. At the same time, the connector of this placement is provided with a quick connector. The wire harness is located inside the cylindrical structure. Through the connecting pipe at the rear end of the cylindrical structure, the threaded sleeve is threadedly fitted with the rear end of the connecting pipe. By rotating the thread, the pressing ring and the expansion pipe are pushed forward. Since the rear end of the expansion pipe is a conical surface, when the pressing ring is pushed forward, the expansion pipe will be inwardly contracted and extruded, and the wire harness located inside will be fixedly locked. The overall structure is more concise and more convenient for fixed installation.

[0008] Preferably, the inner wall of the connecting pipe includes a tapered hole that is thinner at the front end and thicker at the rear end, and the outer wall of the inner connecting pipe is provided with an outer tapered wall adapted to the tapered hole. By providing the tapered hole and the outer tapered wall, the inner connecting pipe is also contracted and pressed inward to provide locking for the wire harness.

[0009] Preferably, the front port of the lamp housing is externally threaded and fitted with a heat dissipation cylinder cover. The outer wall of the heat dissipation cylinder cover is provided with heat dissipation fins. The front end of the heat dissipation cylinder cover is provided with an inwardly extending pressing platform, and the pressing platform presses and fixes the transparent plate to the front port of the lamp housing. By providing the heat dissipation fins on the heat dissipation cylinder cover, its heat dissipation effect can be improved.

[0010] Preferably, a sealing ring is provided between the outer wall of the heat dissipation cylinder cover and the lamp housing. This can improve its sealing effect to cope with harsh environments such as outdoors.

[0011] Preferably, the outer ends of the heat dissipation fins are interconnected by an annular ring. Using the annular ring can improve the strength of the heat dissipation fins and at the same time form a protection for the periphery of the heat dissipation fins to avoid interference with the external environment.

[0012] Preferably, a plurality of reinforcing plates are provided between the lamp housing and the connecting head. By providing the reinforcing plates, the connection strength between the lamp housing and the connecting head can be improved, and at the same time, the reinforcing plates can provide a heat dissipation effect.

[0013] Preferably, a reflective layer is provided in the inner cavity of the lamp housing. The reflective layer can refract the light out.

[0014] Preferably, the inner cavity of the lamp housing includes a cylindrical section at the front section and a conical section at the rear section. The conical section can provide a light condensing effect.

[0015] Preferably, the transparent plate is made of glass material. The glass material has a higher light transmission effect.

[0016] Advantages of the present invention:

[0017] By rotating the thread, the pressing ring expansion tube is pushed forward. Since the rear end of the expansion tube is a conical surface, when the pressing ring is pushed forward, the expansion tube will be contracted and extruded inward, and the wire harness located inside will be fixed and locked. The overall structure is more concise and more convenient for fixed installation. Description of the Drawings
