Description

Technical Field

[0001] The utility model relates to a self-locking device, in particular to a self-locking device which is convenient for installing a ceiling lamp. Background Art

[0002] Ceiling lamps are a common type of lamps, which are mainly connected by adsorption or embedding into the roof ceiling. There are two main methods for installing ceiling lamps on the market: one is to first fix the mounting base of the ceiling lamp on the ceiling, and then connect the lamp body to the lamp holder through bolts or buckle structures; the bolt connection method makes the operation cumbersome, and the buckle structure method is because the ceiling lamp fits the ceiling, the operating space is small during installation, and the user can hardly see the exact position of the buckle, which makes it impossible to achieve convenient installation, and the lamp body is also difficult to disassemble, which is time-consuming and laborious. Another installation method is to use threaded connection, that is, first fix the mounting base of the ceiling lamp on the ceiling, and then connect the lamp body to the lamp holder through threads. This method is relatively simple to install and disassemble, but it is impossible to judge whether the lamp body is rotated in place during actual installation. If the thread is rotated too tightly, it will be very laborious to disassemble later. If the thread is rotated too loosely, the lamp body is prone to loosening or even falling. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model proposes a self-locking device which is convenient for installing a ceiling lamp, facilitates quick positioning and judgment of the ceiling lamp and the lamp holder when installing the ceiling lamp, and can enhance the connection strength between the ceiling lamp and the lamp holder.

[0004] To realize the above technical scheme, the utility model provides a self-locking device for facilitating the installation of ceiling lamps, comprising: an upper cover, a bottom cover and a self-locking clip, wherein the self-locking clip is installed between the upper cover and the bottom cover, the upper cover comprises an upper cover body, a clip positioning and mounting groove is reserved on the front side surface of the upper cover body, a clip slide groove is arranged on the top surface of the upper cover body, and a spring fitting groove is arranged on the top surface of the upper cover body on one side of the clip slide groove; the self-locking clip comprises a clip body, a transverse spring mounting hole is arranged on the rear side surface of the clip body, an elastic pressing column is arranged on the front side surface of the clip body, a transverse spring is installed in the transverse spring mounting hole, and the transverse spring The front end is abutted against the rear end of the elastic pressing column, and the rear end of the transverse spring is abutted against the inner wall of the rear side surface of the upper cover body. The side surface of the buckle body is provided with two upper and lower spring sheets arranged in parallel with each other, and the longitudinal spring is installed between the upper and lower spring sheets. The top surface of the upper spring sheet is provided with a positioning protrusion protruding upward, and the top surface of the buckle body is provided with an oblique wedge block. The front end of the buckle body is installed in the buckle positioning and mounting groove reserved on the upper cover body, and the elastic pressing column protrudes forward, the positioning protrusion provided on the upper spring sheet is located in the spring sheet fitting groove provided on the top surface of the upper cover body, and the oblique wedge block provided on the top surface of the buckle body is located in the buckle slide groove provided on the top surface of the upper cover body.

[0005] In the above technical scheme, during actual installation, the lamp holder of the ceiling lamp is installed on the ceiling, and the self-locking device is installed on the lamp holder. When the lamp body of the ceiling lamp is installed, it is only necessary to insert the positioning fastener provided on the lamp body into the fastener slide groove provided on the self-locking device, and then rotate it. The positioning fastener contacts the oblique wedge block during the rotation, and then pushes the transverse spring backward to retract through the oblique wedge block, so that the fastener body moves backward. When the positioning fastener slides over the oblique wedge block, a "click" sound will be heard, and the transverse spring pushes the fastener body to reset, and the positioning fastener is fastened in the fastener slide groove through the oblique wedge block. At this time, it is proved that the lamp body has been rotated into place, thereby realizing rapid positioning judgment when the lamp body and the lamp holder are installed, and the connection strength between the ceiling lamp and the lamp holder can be enhanced. When the lamp body needs to be disassembled, just press the elastic pressing column to make the fastener body retreat backwards to overcome the elastic force of the transverse spring, and the oblique wedge block retreats with the fastener body to expose the moving channel of the positioning fastener, and then rotate the lamp body in the opposite direction to achieve the separation between the lamp body and the lamp holder. The operation is very convenient.

[0006] Preferably, a rubber plug is installed at the position where the rear end of the transverse spring butts against the inner wall of the rear side of the upper cover body to improve the stability of the docking between the transverse spring and the upper cover body.

[0007] Preferably, a longitudinal spring positioning column is provided on the lower spring sheet, the bottom of the longitudinal spring is sleeved on the longitudinal spring positioning column, and the top of the longitudinal spring is against the bottom surface of the upper spring sheet to improve the stability of the longitudinal spring during installation.

[0008] Preferably, the bottom cover includes a bottom cover body, on which a lower screw hole and a positioning column are provided. After the bottom cover body is docked with the upper cover body, it is positioned by the positioning column, and the lower screw hole is aligned with the upper screw hole provided on the upper cover body and then fixed by screws to achieve quick docking between the bottom cover and the upper cover.

[0009] Preferably, the upper cover, the bottom cover and the self-locking buckle are all formed by integral plastic injection molding.

[0010] The utility model provides a self-locking device for facilitating the installation of a ceiling lamp, which has the following beneficial effects: the self-locking device for facilitating the installation of a ceiling lamp has a reasonable design, a simple structure, a compact size, and is easy to install, which greatly facilitates the rapid positioning judgment when the ceiling lamp and the lamp holder are installed, and can enhance the connection strength between the ceiling lamp and the lamp holder. In actual installation, the lamp holder of the ceiling lamp is installed on the ceiling, and the self-locking device is installed on the lamp holder. When the lamp body of the ceiling lamp is installed, it is only necessary to insert the positioning fastener provided on the lamp body into the fastener slide groove provided on the self-locking device, and then rotate it. The positioning fastener contacts the oblique wedge block during the rotation process, and then the oblique wedge block pushes the transverse spring to shrink backward, so that the fastener body moves backward. When the positioning fastener slides over the oblique wedge block, a "click" sound can be heard, and the transverse spring pushes the fastener body to reset, and the positioning fastener is fastened in the fastener slide groove through the oblique wedge block. At this time, it is proved that the lamp body has been rotated into place, thereby realizing the rapid positioning judgment when the lamp body and the lamp holder are installed, and the connection strength between the ceiling lamp and the lamp holder can be enhanced. When the lamp body needs to be disassembled, just press the elastic pressing column to make the fastener body retreat backwards to overcome the elastic force of the transverse spring, and the oblique wedge block retreats with the fastener body to expose the moving channel of the positioning fastener, and then rotate the lamp body in the opposite direction to achieve the separation between the lamp body and the lamp holder. The operation is very convenient. BRIEF DESCRIPTION OF THE DRAWINGS
