Description

Technical Field

[0001] The utility model relates to the technical field of lighting equipment, in particular to a hinge structure of a lamp. Background Art

[0002] Existing high-power lamps are often very heavy and require the cover to be opened for wiring during installation. At this time, if a hinge structure is designed in the wiring cavity of the lamp, it will greatly facilitate the installation.

[0003] At present, the hinges of lamps are closed, which act as a connecting shaft when the cover of the lamp is opened. However, when installing the lamp with a hanging rod, the cover needs to be installed on the hanging rod first, so the cover needs to be removed first. At this time, the closed hinge needs to be opened quickly, but after installing the cover, it is difficult to align the hinge installation hole and then insert the hinge shaft because of the heavy weight of the lamp. The lamp body cannot be hung on the upper cover quickly, and it often requires two people to work together, and it takes a long time.

[0004] Another common type is the open type, which solves the problem of quick suspension of the boom type installation, but when installed as a conventional U-shaped bracket, it cannot realize the function of the rotating shaft. After opening the cover, the cover and the lamp body are separated, and the placement of the cover needs to be considered. At the same time, when closing the cover, the fixing bolt holes of the cover and the lamp body cannot be quickly aligned. There is a lack of a composite hinge structure that solves the problems of the above two installation scenarios at the same time. Utility Model Content

[0034] Specifically, it includes a fixed hinge 1 and a movable hinge 2, with a rotating shaft 3 disposed between the fixed hinge 1 and the movable hinge 2; the upper end of the fixed hinge 1 is provided with a snap-fit ​​member 25, and the snap-fit ​​member 25 is fixedly connected to the lamp upper cover 20. The bottom end of the support assembly 11 is fixedly connected to the lamp body 10 of the lamp.

[0035] The fixed hinge 1 includes a support assembly 11 and a first fixed shaft 12 and a second fixed shaft 13 transversely arranged on the support assembly 11, and the movable hinge 2 includes a movable shaft 21 and a first rotating hook 22 and a second rotating hook 23 arranged on both sides of the movable shaft 21; the first rotating hook 22 is hooked to the first fixed shaft 12, the second rotating hook 23 is hooked to the second fixed shaft 13, and the rotating shaft 3 passes through the first fixed shaft 12, the second fixed shaft 13 and the movable shaft 21 for rotational connection. The rotating shaft 3 includes a first rotating shaft 31 and a second rotating shaft 32 which are threadedly connected; the lower end of the first rotating shaft 31 is provided with an internal thread, and the second rotating shaft 32 is provided with an external thread.

[0036] Preferably, a supporting cross bar 14 is provided between the first fixed shaft 12 and the second fixed shaft 13, and the movable shaft 21 is attached to the supporting cross bar 14. An angle limiting member 24 is provided outside the movable shaft 21 to clamp and limit the supporting cross bar 14.

[0037] Preferably, the first fixed shaft 12, the second fixed shaft 13 and the movable shaft 21 are all provided with through holes, and the through holes in the first fixed shaft 12, the second fixed shaft 13 and the movable shaft 21 are connected when the fixed hinge 1 and the movable hinge 2 are installed and connected.

[0038] Preferably, the support assembly 11 includes a first support leg 11-1 disposed at both ends of the first fixed shaft 12 to support and fix the first fixed shaft 12, and a second support leg 11-2 disposed at both ends of the second fixed shaft 13 to support and fix the second fixed shaft 13. The first support leg 11-1 and the second support leg 11-2 are triangular support plates.

[0039] Preferably, the rotating shaft 3 adopts a stainless steel parent-child pin shaft. The parent-child pin structure is convenient for quick disassembly and assembly, and the stainless steel material ensures strength and corrosion resistance.

[0040] Reference Figure 4 , 5 , is a schematic diagram of the structure of the hinge structure of the utility model used in a U-shaped bracket lamp, the first rotating hook 22 is hooked and connected with the first fixed axis 12, the second rotating hook 23 is hooked and connected with the second fixed axis 13, and the moving axis 21 is attached to the supporting cross bar 14; the rotating axis 3 adopts a parent-child pin; the first rotating axis 31 passes through the first fixed axis 12, the second fixed axis 13 and the moving axis 21 for rotational connection, and the second rotating axis 32 is locked and connected with the first rotating axis 31. When installing the U-shaped bracket lamp, it is only necessary to flip the upper cover 20 of the lamp upward to realize the function of the rotating axis. After opening the cover, the angle limiting member 24 clamps against the supporting cross bar 14 to prevent the upper cover from moving. The upper cover 20 and the lamp body 10 are connected together and do not need to be separated. There is no need to consider the placement of the cover. At the same time, it is convenient and quick to close the cover, which solves the problem that the open hinge connection needs to align the fixing bolt holes of the cover and the lamp body and the placement of the cover; in terms of overall shape and structural design, the appearance impact of the U-shaped bracket of the floodlight when in use is greatly weakened.

[0041] Reference Figure 6-9 , is a schematic diagram of the structure of the hinge structure of the utility model used in a boom-type lamp. When installing the boom-type lamp, first remove the upper cover 20, and then install the upper cover 20 on the installation carrier; hang the fixed hinge 1 on the lamp body 10 on the movable hinge 2 of the upper cover 20, and then pass the first rotating shaft 31 through the first fixed shaft 12, the second fixed shaft 13 and the movable shaft 21, and lock it with the second rotating shaft 32, and then connect the wires in the lamp body 10. After completion, close the cavity and lock the cover bolts. At this time, one person completes the installation of the lamp. Originally, two people were needed, one to hold the lamp and the other to connect the wires; it greatly saves manpower and time. It solves the problem that the closed hinge needs to be opened quickly, and it is difficult to align the weight of the lamp with the hinge mounting hole and then put on the hinge shaft.

[0042] The utility model is a composite hinge structure that solves the hinge pain points of lamps in two common installation scenarios (hanging rod installation and U-shaped bracket installation). It has both the rotating shaft function of the closed hinge and the quick suspension function of the open hinge as an installation carrier. At the same time, the hinge shaft can be quickly disassembled.

[0043] The fixed hinge 1 of the utility model is connected to the lamp body and acts as a hook; the movable hinge 2 is connected to the upper cover of the lamp as a hanging carrier of the lamp body during installation; the rotating shaft 3 plays the role of positioning the rotating shaft when closing the cover, so that the threaded holes of the cover and the lamp body can be quickly aligned. When the U-shaped bracket is installed, the rotating shaft 3 is required to close the cover; when the suspension rod is installed, the upper cover 20 of the lamp needs to be disassembled and installed first, so the rotating shaft needs to be designed as a structure that can be quickly disassembled; the parent-child nail structure of the rotating shaft 3 is particularly suitable for quick disassembly and assembly.

[0044] The hinge structure of the lamp of the present invention can realize the fast installation of the lamp, and facilitate the inspection and maintenance. When the current high-power lamps are installed in a boom-type manner, the upper cover is rarely designed to be a hanging body, so it is very inconvenient to connect the wires when installing the lamp; and when the lamp is used as a high-power floodlight, it needs to be installed with a U-shaped bracket, which has a greater impact on the shape. The composite structure of the hinge of the present invention can design a part of the hinge structure on the upper cover of the lamp boom-type installation connection, so that when installing, the lamp body can be hung on the upper cover, and then the wiring can be carried out, so that the installation of the lamp can be completed by one person; at the same time, the rotating shaft also realizes the function of fixing the rotating shaft when the U-shaped bracket is installed and the placement of the cover after opening the cover; in addition, in terms of the shape and structure design, the appearance impact of the U-shaped bracket of the floodlight when in use is greatly weakened.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it; although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace part or all of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
