Technical Field

[0001] The utility model belongs to the technical field of downlights and relates to a rotating structure of a downlight. Background Art

[0002] Downlights are commonly used lighting fixtures in lighting devices. They are very popular because they are easy to use and energy-saving. In actual use, especially when used in exhibitions and other places, it is usually necessary to adjust the irradiation angle of the downlight.

[0003] Therefore, the existing downlight, such as the Chinese patent application [Authorization Announcement No.: CN210979538U] discloses a light source rotation structure, including a face ring, a rotating ring and a fixed cylinder, the rotating ring is coaxially rotatably arranged in the face ring, the face ring is provided with a limiter for limiting the axial freedom of the rotating ring, the fixed cylinder is swingably arranged in the rotating ring, the fixed cylinder is used to fix the light source, the swing axis of the fixed cylinder is perpendicular to the axial direction of the rotating ring, the fixed cylinder realizes axial rotation around the face ring with the help of the rotation cooperation between the rotating ring and the face ring, and at the same time, the fixed cylinder realizes swinging around the axial direction perpendicular to the axial direction of the rotating ring with the help of the swing axis of the rotating ring.

[0004] The above structure rotates the entire rotating ring so that the fixed tube and the rotating ring rotate along the surface ring. During the rotation process, the swing shaft needs to be rotated synchronously, which causes the swing shaft to shake during rotation, affecting the accuracy of subsequent swing adjustment and reducing the accuracy of the downlight angle adjustment. Utility Model Content

[0005] The purpose of the utility model is to solve the above problems in the existing technology and propose a rotating structure of a downlight. The technical problem to be solved by the utility model is: how to solve the problem of poor adjustment accuracy and stability of the existing downlights.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A rotation structure of a downlight, the downlight comprises a lamp body and a fixing seat, the lamp body comprises a connecting shell and a lighting component located in the connecting shell, and the characteristic is that the lighting component can rotate circumferentially along the connecting shell, the connecting shell is outerly provided with an annular fixing shell, the fixing shell is tightly fitted with a hinge shaft, the hinge shaft can rotate circumferentially under the action of external force, the hinge shaft is fixedly connected to the connecting shell, the fixing shell has a positioning ring protruding radially outward, the fixing seat comprises an annular supporting ring, the positioning ring is placed on the supporting ring, and the fixing seat is connected with a positioning component for axially positioning the positioning ring on the supporting ring.

[0008] Working principle: During installation, first fix the fixing seat on the external wall or other fixed base. The fixing seat has an annular support ring, and a fixing shell is arranged inside the fixing seat. The positioning ring on the fixing shell is placed on the support ring, and the positioning ring and the support ring are axially positioned by the positioning piece. When the lighting component needs to be rotated circumferentially, the lighting component can be directly pushed to rotate circumferentially along the connecting shell. When the lighting component needs to be swung, the lighting component and the connecting shell can be directly driven to rotate the hinge shaft synchronously. At this time, the hinge shaft can rotate along the hinge point, and because the fixing shell and the hinge shaft are tightly fitted, the external Under the action of force, the hinge shaft will rotate synchronously with the connecting shell relative to the fixed shell. In the absence of external force, the positioning is achieved through the friction between the hinge shaft and the fixed shell, so that the connecting shell will not swing circumferentially with the fixed shell when adjusting the circumferential angle, thereby improving the stability and accuracy of the adjustment. When connected, it is connected to the fixed seat through the fixed shell, and the fixed shell and the fixed seat will not rotate circumferentially. During the circumferential rotation, only the lighting component rotates, making the adjustment more convenient and having less impact on the connection between the lamp body and the fixed seat, further improving the stability of the connection between the lamp body and the fixed seat.

[0009] The lighting component is a lighting lamp or a lighting panel, etc.

[0010] In the above-mentioned rotating structure of the downlight, the fixing seat has mounting columns arranged one-to-one corresponding to the positioning members, and the positioning members are positioning plates, which include a connecting portion arranged horizontally and placed on the mounting columns and a limiting portion arranged vertically and pressed on the positioning ring, and the positioning plate is fixedly connected to the corresponding mounting columns by fasteners.

[0011] By providing a mounting column, the connecting portion of the positioning plate can be stably pressed onto the mounting column by fasteners. At this time, the limiting portion also presses the positioning ring onto the supporting ring as the connecting portion is positioned, thereby achieving axial positioning of the positioning ring and the supporting ring and improving the stability of the installation of the fixing seat and the fixing shell.

[0012] In the above-mentioned rotating structure of the downlight, the lower end of the limiting portion is bent toward the direction of the lighting component to form a limiting stop edge, and the lower end of the limiting stop edge is close to the positioning ring.

[0013] The setting of the limit stop edge increases the contact area between the limit part and the positioning ring, making the positioning of the limit part on the positioning ring more stable.

[0014] In the above-mentioned rotating structure of the downlight, there are three positioning plates, which are evenly distributed along the circumference of the fixing seat, and there are two hinge shafts, which are symmetrically arranged along the axis of the fixing shell, and one of the positioning plates is arranged radially opposite to one of the hinge shafts along the radial direction of the fixing shell.

[0015] The arrangement of this structure makes the distribution of the positioning plate and the hinge axis more reasonable, further improves the stability of the positioning of the fixed shell and the fixed seat, and ensures that the fixed shell will not be displaced during rotation, thereby improving the stability of adjustment.

[0016] In the above-mentioned rotating structure of the downlight, the fixed shell is recessed radially inward to form a hinge portion, the inner side of the hinge portion abuts against the outer side of the connecting shell, and the end of the hinge shaft is threadedly connected to the connecting shell.

[0017] The arrangement of the hinged portion makes the connection between the fixed shell and the connecting shell more stable, avoids radial movement of the fixed shell and the connecting shell during rotation, and does not affect the connection between the fixed shell and the fixing seat.

[0018] In the above-mentioned rotation structure of the downlight, the connecting shell has at least one travel limit plate bent inwardly, and an adjustment groove corresponding to the travel limit plate is circumferentially opened on the lighting component. The travel limit plate is embedded in the corresponding adjustment groove, and the lighting component and the travel limit plate can move relative to each other in the circumferential direction.

[0019] The setting of the travel limit plate enables the lighting component to stably rotate along the circumference of the connecting shell, thereby ensuring the stability of the adjustment.

[0020] In the above-mentioned rotating structure of the downlight, the travel limit plate is arranged to be inclined upward and inward from bottom to top, and the upper end of the travel limit plate abuts against the groove top of the adjusting slide groove.

[0021] The arrangement of this structure enables the travel limit plate to not only have a travel limit function, but also to provide an upward supporting force for the lighting component, thereby making the connection between the lighting component and the connecting shell more stable.

[0022] In the above-mentioned rotating structure of the downlight, the positioning member is a plurality of bolts, and the positioning ring and the supporting ring are fixedly connected by bolts.

[0023] The fixing shell and the fixing seat are fixed by using common parts, which improves the stability of the installation.

[0024] Compared with the prior art, the utility model has the following advantages: when the lighting component needs to be rotated circumferentially, the lighting component can be directly pushed to rotate circumferentially along the connecting shell; when the lighting component needs to be swung, the lighting component and the connecting shell can be directly and synchronously driven to rotate the hinge shaft. At this time, the hinge shaft can rotate along the hinge point, and because the fixed shell and the hinge shaft are tightly fitted, the hinge shaft will rotate synchronously with the connecting shell relative to the fixed shell under the action of external force. In the absence of external force, positioning is achieved through the friction between the hinge shaft and the fixed shell, so that the connecting shell will not swing circumferentially with the fixed shell when adjusting the circumferential angle, making the adjustment more convenient, with less impact on the connection between the lamp body and the fixed seat, and further improving the stability of the connection between the lamp body and the fixed seat.
