Description

Technical Field

[0001] This utility model relates to a rotating snap-on ceiling light. Background Technology

[0002] Rotary snap-fit ​​ceiling lights are a commonly used ceiling light installation technology. For example, Chinese Utility Model Patent CN 211011060 U discloses a ceiling light mounting plate and a ceiling light, including a ceiling plate and a light body connected to the ceiling plate. The ceiling plate and the light body are connected by a rotary snap-fit ​​structure. The rotary snap-fit ​​structure includes a circular connecting ring at the front end of the ceiling plate and an arc-shaped groove structure on the outer wall of the circular connecting ring. One end of the horizontal arc-shaped groove on the arc-shaped groove structure is open, and the width of the arc-shaped groove gradually decreases from the open end to the closed end. The second snap-fit ​​structure includes a groove on the back of the light body that matches the circular connecting ring. A protrusion that matches the arc-shaped groove is provided on the inner wall of the groove. The circular connecting ring is inserted into the groove, and by rotation, the protrusion engages with the corresponding arc-shaped groove, thus achieving the connection and fixation between the light body and the ceiling plate.

[0003] The existing technology discloses a rotating buckle that enables quick installation of ceiling lights; however, the safety of this rotating buckle structure needs to be improved. Utility Model Content

[0004] The purpose of this utility model is to provide a rotating snap-on ceiling light, including a lamp body with an internal LED light source module and a mounting plate for fixed installation on the ceiling. The top of the lamp body has a recessed cavity for accommodating the mounting plate. A rotating snap is provided between the lamp body and the mounting plate to suspend the lamp body on the mounting plate. The rotating snap locks when the lamp body rotates relative to the mounting plate in a first direction and unlocks when it rotates in a second direction, wherein the first direction and the second direction are opposite. The rotating snap includes an arc-shaped groove on the edge of the mounting plate and a protrusion on the side wall of the recessed cavity. There are multiple arc-shaped grooves, each protruding along the diameter direction of the mounting plate. The number of protrusions is equal to the number of arc-shaped grooves. Each protrusion extends circumferentially around the axis of the lamp body in an arc shape. Each protrusion is inserted into one arc-shaped groove. The first end of each protrusion has an axial channel extending along the axis of the lamp body for the arc-shaped groove to enter and exit the protrusion. The end of each protrusion has a locking structure to prevent the lamp body from rotating in the second direction.

[0021] The following description, in conjunction with the accompanying drawings, further illustrates the proposed solution.

[0022] like Figures 1 to 9A rotating snap-on ceiling light, as shown, includes a lamp body 10 with an internal LED light source module (not shown) and a mounting plate 20 for fixed installation on the ceiling. The top of the lamp body 10 has a recessed cavity 101 for accommodating the mounting plate 20. In this embodiment, both the mounting plate 20 and the recessed cavity 101 of the lamp body are circular. A rotating snap-on fastener is provided between the lamp body 10 and the mounting plate 20 to suspend the lamp body 10 on the mounting plate 20. The rotating snap-on fastener locks when the lamp body 10 rotates relative to the mounting plate 20 in a first direction and unlocks when rotated in a second direction. The rotating buckle, with one direction opposite to the second, includes an arc-shaped groove 201 on the edge of the mounting plate 20 and protruding buckles 102 on the side wall of the recess 101. There are multiple arc-shaped grooves 201; in this embodiment, three are shown in the figure. All arc-shaped grooves 201 are evenly spaced circumferentially around the axis of the mounting plate 20. The number of protruding buckles 102 is equal to the number of arc-shaped grooves 201. All protruding buckles 102 are evenly spaced circumferentially around the axis of the lamp body. After the lamp body 10 is installed on the mounting plate 20, the axis of the lamp body 10 coincides with the axis of the mounting plate 20.

[0023] Each arc-shaped slot 201 is fitted with a protruding buckle 102. Each protruding buckle 102 enters an arc-shaped slot 201 when the lamp body 10 rotates in the first direction. In this embodiment, the structure of the arc-shaped slot 201 and the structure of the protruding buckle 102 can be referred to the prior art mentioned in the background art.

[0024] Each protruding buckle 102 is provided with a locking structure that prevents the lamp body 10 from rotating in the second direction after the protruding buckle 102 enters the arc-shaped slot 201. This technical solution can prevent the lamp body from accidentally falling off through the locking structure, thereby improving safety and reliability.

[0025] The locking structure includes a protrusion 104 on the buckle 102 and a recess 202 in the arc-shaped groove 201. The protrusion 104 sinks into the recess 202 after the buckle 102 enters the arc-shaped groove 201.

[0026] The locking structure disclosed in this technical solution is simple and easy to implement. It utilizes the bulge to sink into the recess, so that when the lamp body is rotated in the second direction, a sufficient rotational force needs to be applied to the lamp body to make the bulge move out of the recess, thereby achieving the purpose of preventing the lamp body from rotating in the second direction.

[0027] In this embodiment, in addition to the matching structure of the protrusion and the recess, the locking structure can also be a damping mechanism that generates a certain damping force between the lamp body and the mounting plate. Such a damping structure can be achieved using existing technology, and will not be described in detail here.

[0028] The bottom of the cavity 101 is provided with multiple conductive pins 30 that are electrically connected to the LED light source module inside the lamp body 10. Each conductive pin 30 includes a pin shank 301 and a pin tip 302. The diameter of the pin tip 302 is larger than the diameter of the pin shank 301. All conductive pins 30 are evenly spaced around the axis of the lamp body 10. In this embodiment, Figure 2 The number of conductive needles shown is 3;

[0029] The hanging plate 20 is provided with multiple hanging grooves 203. All hanging grooves 203 are evenly distributed around the axis of the hanging plate 20. Each hanging groove 203 extends around the axis of the hanging plate 20 in an arc shape. The number of hanging grooves 203 is equal to the number of conductive needles 30. The groove width D of each hanging groove is greater than or equal to the diameter of the needle bar 301 but less than the diameter of the needle head 302. The first end of each hanging groove 203 is provided with a groove end 204 with a diameter greater than the diameter of the needle head 302 so that the needle head can pass through the groove.

[0030] Each hanging slot 203 is used to suspend a conductive needle 30. The needle tip 302 passes through the slot end 204 and then rotates with the lamp body 10 in a first direction so that the needle tip rotates to the tail end of the hanging slot 203. Figure 9 The direction indicated by the arrow is the first direction;

[0031] Each hanging slot 203 has a conductive sheet 40 at its tail end that is electrically connected to a power supply (not shown in the figure). The conductive sheet 40 contacts the needle 302 that has rotated to the tail end of the hanging slot and conducts electricity.

[0032] This technical solution allows the conductive pin to be suspended in the mounting slot of the mounting plate, working together with the rotating buckle to suspend the lamp body, providing stability and reliability for the lamp body and ensuring safety. Furthermore, the lamp body achieves conductivity through contact between the conductive pin and the conductive sheet, reducing manual wiring and simplifying installation.

[0033] Each conductive sheet 40 is an elastic sheet, and each conductive sheet 40 has a receiving space 401 for accommodating the needle 302 and an opening 402 that communicates with the receiving space 401 and allows the needle 302 to enter and exit the receiving space 401. The width L of the opening is smaller than the diameter of the needle 302.

[0034] This technical solution, by designing the width of the opening to be smaller than the diameter of the needle, prevents the needle from leaving the receiving space after it enters the receiving space of the conductive sheet, thus preventing the lamp body from rotating in the second direction, further avoiding accidental detachment of the lamp body, and improving safety and reliability.

[0035] When installing the lamp body, a certain rotational force needs to be applied to the lamp body to rotate it in the first direction so that the needle tip can be forced into the receiving space after expanding the opening of the conductive sheet.

[0036] The hanging plate 20 is also provided with a protective cover 50 that covers all the hanging slots 203, conductive sheets 40 and conductive pins 30.

[0037] This technical solution protects the conductive sheet and conductive needle by setting up a protective cover, which can prevent dust and insects.

[0038] The edge of the protective cover 50 is provided with a wire connector 60. The inner end of the wire connector 60 is electrically connected to the conductive sheet 40 inside the protective cover 50 through a wire (not shown in the figure). The outer end of the wire connector 60 extends out of the protective cover 50 for electrical connection with the power supply wire.

[0039] This technical solution facilitates manual connection of the power supply by setting up wire connectors. In this embodiment, the power supply can be, for example, mains power.

[0040] The bottom of the cavity 101 is also provided with a central protrusion 103, and the axis of the central protrusion 103 coincides with the axis of the lamp body 10.

[0041] The mounting plate 20 is also provided with a positioning hole 205 for the central protrusion 103 to be inserted, and the axis of the positioning hole 205 coincides with the axis of the mounting plate 20.

[0042] When installing the lamp body, insert the central protrusion 103 of the lamp body into the positioning hole 205 to position the lamp body and the mounting plate. The cooperation between the central protrusion 103 and the positioning hole 205 facilitates the installation of the lamp body.
