[0013] Preferably, the auxiliary contraction assembly includes a first pulling member connected to the conical cylinder. One end of the first pulling member away from the conical cylinder passes through the annular outer shell and is connected to the movable rod, and the movable rod and the main rod are inserted into each other.

[0014] Preferably, the movable rod includes a rod body slidably connected to the main rod and an inserting rod slidably connected inside the rod body. A sliding groove for the inserting rod to slide is formed on the rod body, a second elastic element is arranged between the inner wall of the sliding groove and the inserting rod, a jack matching with the inserting rod is formed on the main rod, a first inclined surface is formed on one side of the end of the inserting rod, and one end of the first pulling member away from the conical cylinder passes through the annular outer shell and the rod body and is connected to the inserting rod.

[0015] Preferably, the auxiliary contraction assembly further includes a second pulling member connected to the conical cylinder. One end of the second pulling member away from the conical cylinder passes through the annular outer shell and is connected to the main rod. The first pulling member and the second pulling member have the same structure, and both include a pneumatic elastic telescopic member and a rope body connected to the pneumatic elastic telescopic member. The pneumatic elastic telescopic members of the first pulling member and the second pulling member are both connected to the conical cylinder.

[0016] Preferably, a movable hole for the rope body to pass through is formed in the annular outer shell. A sealing plug is arranged at the port of the movable hole of the annular outer shell. A cavity is arranged in the sealing plug. Multiple folds are arranged on the inner side wall of the sealing plug. The pneumatic elastic telescopic member includes a tube body connected to the conical cylinder, a piston slidably connected in the tube body, a third elastic element arranged between the piston and the inner wall of the tube body, and a telescopic rod arranged on the piston and connected to the rope body.

[0017] Preferably, the positioning assembly includes a positioning groove formed on the conical cylinder, a positioning rod slidably connected in the positioning groove, and a fourth elastic element arranged between the inner wall of the positioning groove and the positioning rod. A positioning hole matching with the positioning rod is formed on the inner side wall of the annular outer shell, and a second inclined surface is formed on the lower side of the end of the positioning rod.

[0018] An LED spotlight using an LED spotlight face cover includes a spotlight body. The spotlight body is threadedly connected to a pedestal, and the spotlight body is movably abutted against the top plane of the pedestal.

[0019] The present invention also discloses a using method of an LED spotlight, including the following steps:

[0020] S1: When the LED downlight is in use, thread the downlight body onto the pedestal. The downlight body and the downlight face cover are integrated. At this time, the positioning rod is placed on the lower side of the panel. Then, pass the downlight body through the LED downlight hole groove reserved in the indoor ceiling until the spring clip enters the interior of the indoor ceiling.

[0021] S2: Subsequently, the staff manually toggles the positioning rod, and the positioning rod contracts into the positioning groove. There is no longer any restriction between the conical cylinder and the annular shell. The conical cylinder moves upward under the pull of the elastic telescopic tube. The conical cylinder contracts into the annular shell until the positioning rod aligns with the positioning hole. The positioning rod is pushed into the positioning hole by the elastic force of the fourth elastic element to position the conical cylinder and the annular shell.

[0022] S3: After the conical cylinder moves upward, the first pulling member and the second pulling member are no longer stressed. The main rod first rotates back to its original position under the action of the torsion spring. The rod body slides outside the main rod under the pull of the first elastic element. Finally, the reset swing rod drives the abutting rod to abut against the inner wall of the ceiling, fixing the downlight body to the indoor ceiling through the downlight face cover.

[0023] S4: When the LED downlight needs to be disassembled, the staff places two fingers in the annular groove of the conical cylinder and uses other fingers to push up the panel. Then, the fingers press down the conical cylinder, and the conical cylinder moves downward relative to the annular shell, stretching the elastic telescopic tube.

[0024] S5: When the conical cylinder moves downward, both the first pulling member and the second pulling member are stressed. The pneumatic elastic telescopic members of the first pulling member and the second pulling member are both stretched. The pneumatic elastic telescopic members extract the air in the sealed plug cavity, and the sealed plug no longer expands, creating a gap between the rope body and the sealed plug, facilitating the subsequent smooth pulling of the rope body.

[0025] S6: As the rope body of the first pulling member starts to be stressed, the rope body of the first pulling member exerts a pulling force on the plug rod, and the plug rod slides into the chute. There is no longer any restriction between the rod body and the main rod. As the rope body of the first pulling member continues to be pulled, the rod body slides relative to the main rod, and the length of the swing rod shortens and gradually moves away from the inner wall of the ceiling.

[0026] As the rope body of the second pulling member starts to be stressed, the rope body of the second pulling member pulls the main rod, and the main rod is stressed and approaches the outer wall of the annular shell.

[0027] S7: As the conical cylinder moves towards the outside of the annular shell, the positioning rod is no longer abutted against the inner wall of the annular shell. The positioning rod moves out of the positioning groove under the elastic force of the fourth elastic element and abuts against the bottom wall of the panel to limit the position of the conical cylinder and the annular shell. At this time, the staff can smoothly pick up the LED downlight falling from the ceiling hole groove.

[0028] Compared with the prior art, the present invention provides an LED spotlight face cover, an LED spotlight using the face cover, and a method for using the same, having the following beneficial effects:

[0029] 1. For the LED spotlight face cover, the LED spotlight using the face cover, and the method for using the same, the auxiliary contraction component is used to assist in contracting the spring clip, so that the LED spotlight can be quickly disassembled and assembled from the reserved hole in the ceiling, thereby reducing the time and difficulty consumed by people when disassembling the spotlight, increasing the convenience of the device, and avoiding the pressure caused between the spring clip and the ceiling when the spring clip is pulled down, eliminating improper damage and ensuring the integrity of the interior decoration.

[0030] 2. For the LED spotlight face cover, the LED spotlight using the face cover, and the method for using the same, the insertion rod is provided to position the main rod and the rod body, avoiding the relative sliding between the main rod and the rod body when the spring clip positions the LED spotlight, resulting in poor positioning effect of the spring clip. When the LED spotlight needs to be disassembled, the auxiliary contraction component pulls the insertion rod, so that the insertion rod contracts in the rod body, facilitating the automatic contraction of the swinging rod, thereby realizing the quick disassembly of the LED spotlight.

[0031] 3. For the LED spotlight face cover, the LED spotlight using the face cover, and the method for using the same, while the auxiliary contraction component pulls the rod body, the main rod is moved closer to the annular housing, avoiding the rod body contacting the annular housing as the rod body contracts without changing the direction of the main rod, which affects the contraction work of the rod body, thereby facilitating the smooth contraction of the rod body.

[0032] 4. For the LED spotlight face cover, the LED spotlight using the face cover, and the method for using the same, by providing a pneumatic telescopic elastic member, when the pneumatic elastic telescopic member is not stretched, the sealing plug expands and abuts against the rope body for sealing, avoiding external dust or water vapor from entering through the gap between the rope body and the annular housing, thereby ensuring the service life of the LED spotlight.

[0053] Specifically, when the LED spotlight is in use, the spotlight body 16 is threadedly connected to the pedestal 3, the spotlight body 16 and the spotlight face cover are combined into one body, the auxiliary contraction assembly contracts the spring clips 6, and then the spotlight body 16 is passed through the LED spotlight hole groove reserved in the indoor ceiling until the spring clips 6 enter the interior of the indoor ceiling, the restriction of the auxiliary contraction assembly on the spring clips 6 is released, the spring clips 6 are abutted against the inner wall of the ceiling, so that the spotlight body 16 is fixed on the indoor ceiling through the spotlight face cover; when the LED spotlight needs to be disassembled, two fingers of the staff are placed in the annular groove 401 of the conical cylinder 4 and the panel 2 is pushed up by other fingers, and then the conical cylinder 4 is pressed down by the fingers, the conical cylinder 4 moves downward relative to the annular housing 1, the elastic telescopic tube 5 is stretched, and the spring clips 6 are assisted to contract through the auxiliary contraction assembly, so that the LED spotlight can be quickly disassembled and assembled from the reserved hole in the ceiling, thereby reducing the time and difficulty consumed by people when disassembling the spotlight, increasing the convenience of the device, and avoiding the pressure caused between the spring clips 6 and the ceiling when the spring clips 6 are pulled down, eliminating improper damage and ensuring the integrity of the indoor decoration.

[0054] Example 2: Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9, An LED spotlight face cover. Based on Embodiment 1, further, the spring clip 6 includes a support plate 601 fixedly arranged on the outer wall of the annular housing 1, a rotating rod 602 rotatably connected to the support plate 601, a torsion spring 603 sleeved on the rotating rod 602, a swing rod 604 fixedly connected to the end of the rotating rod 602, and an abutting rod 605 connected to the end of the swing rod 604 far from the rotating rod 602. The two ends of the torsion spring 603 are respectively connected to the support plate 601 and the swing rod 604.

[0055] Further, the swing rod 604 includes a main rod 6041 fixedly connected to the rotating rod 602 and a movable rod 6042 slidably connected to the outside of the main rod 6041. A guiding strip 6043 is fixedly arranged on the movable rod 6042, a guiding groove 6044 for the guiding strip 6043 to slide is formed on the main rod 6041, and a first elastic element 606 is arranged between the main rod 6041 and the abutting rod 605. The first elastic element 606 is a spring.

[0056] Further, the auxiliary contraction assembly includes a first pulling member 7 connected to the conical cylinder 4. One end of the first pulling member 7 far from the conical cylinder 4 passes through the annular housing 1 and is connected to the movable rod 6042, and the movable rod 6042 and the main rod 6041 are inserted into each other.

[0057] Further, the movable rod 6042 includes a rod body 8 slidably connected to the main rod 6041 and an insertion rod 801 slidably connected inside the rod body 8. A sliding groove 802 for the insertion rod 801 to slide is formed on the rod body 8, a second elastic element 803 is arranged between the inner wall of the sliding groove 802 and the insertion rod 801. The second elastic element 803 is a spring. A jack 9 matching with the insertion rod 801 is formed on the main rod 6041. A first inclined surface is formed on one side of the end of the insertion rod 801. One end of the first pulling member 7 far from the conical cylinder 4 passes through the annular housing 1 and the rod body 8 and is connected to the insertion rod 801.

[0058] Specifically, when the LED spotlight needs to be disassembled, the staff places two fingers in the annular groove 401 of the conical cylinder 4 and uses other fingers to push up the panel 2, and then presses down the conical cylinder 4 with the fingers. The conical cylinder 4 moves downward relative to the annular housing 1, and the elastic telescopic tube 5 is stretched. When the conical cylinder 4 moves downward, the first pulling member 7 is stressed. As the rope body 12 of the first pulling member 7 starts to be stressed, the rope body 12 of the first pulling member 7 applies a pulling force to the insertion rod 801, and the insertion rod 801 slides into the sliding groove 802. There is no longer a restriction between the rod body 8 and the main rod 6041. As the rope body 12 of the first pulling member 7 continues to be pulled, the rod body 8 slides relative to the main rod 6041, the length of the swing rod 604 shortens and gradually moves away from the inner wall of the ceiling, facilitating the swing rod 604 to drive the abutting rod 605 to automatically contract, thereby realizing the rapid disassembly of the LED spotlight, avoiding the pressing between the spring clip 6 and the ceiling when it is pulled down, eliminating improper damage, and ensuring the integrity of the interior decoration.

[0059] Embodiment 3: Refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 , an LED spot lamp face cover. On the basis of Embodiment 2, further, the auxiliary contraction assembly further includes a second pulling member 10 connected to the conical cylinder 4. One end of the second pulling member 10 away from the conical cylinder 4 passes through the annular housing 1 and is connected to the main rod 6041. The first pulling member 7 and the second pulling member 10 have the same structure, and both include a pneumatic elastic telescopic member 11 and a rope body 12 connected to the pneumatic elastic telescopic member 11. The pneumatic elastic telescopic members 11 of the first pulling member 7 and the second pulling member 10 are both connected to the conical cylinder 4.

[0060] Further, when the conical cylinder 4 moves downward, the second pulling member 10 is stressed. As the rope body 12 of the second pulling member 10 starts to be stressed, the rope body 12 of the second pulling member 10 pulls the main rod 6041, and the main rod 6041 is stressed and approaches the outer wall of the annular housing 1, avoiding that when the direction of the main rod 6041 remains unchanged, as the rod body 8 contracts, the rod body 8 abuts against the annular housing 1, affecting the contraction work of the rod body 8, so as to facilitate the smooth contraction of the rod body 8.

[0061] Embodiment 4: Refer to Figure 1 , Figure 2 , Figure 10 and Figure 11 , an LED spot lamp face cover. On the basis of Embodiment 3, further, an activity channel for the rope body 12 to pass through is opened in the annular housing 1. A sealing plug 13 is arranged at the port of the activity channel of the annular housing 1. A cavity 131 is arranged in the sealing plug 13. A plurality of layers of folds 132 are arranged on the inner side wall of the sealing plug 13. The pneumatic elastic telescopic member 11 includes a pipe body 111 connected to the conical cylinder 4, a piston 112 slidably connected in the pipe body 111, a third elastic element 113 arranged between the piston 112 and the inner wall of the pipe body 111, and a telescopic rod 114 arranged on the piston 112 and connected to the rope body 12. The third elastic element 113 is a spring. A gas guide pipe is communicated between the rod chamber of the pipe body 111 and the cavity 131 of the sealing plug 13.

[0062] Specifically, when the conical cylinder 4 moves downward, both the first pulling member 7 and the second pulling member 10 are stressed, and the pneumatic elastic telescopic members 11 of the first pulling member 7 and the second pulling member 10 are stretched. The pneumatic elastic telescopic members 11 extract the air in the cavity 131 of the sealing plug 13, and the sealing plug 13 no longer expands, creating a gap between the rope body 12 and the sealing plug 13, facilitating the subsequent smooth pulling of the rope body 12. After the LED spotlight is installed, when the pneumatic elastic telescopic member 11 is not stretched, the sealing plug 13 expands and abuts and seals the rope body 12. The arrangement of the multi-layered folds 132 can further improve the sealing effect between the sealing plug 13 and the rope body 12, preventing external dust from entering through the gap where the rope body 12 is connected to the annular housing 1, thereby ensuring the service life of the LED spotlight.

[0063] Embodiment 5: Refer to Figure 3 、 Figure 4 and Figure 5 , an LED spotlight face cover. On the basis of Embodiment 4, further, the positioning assembly includes a positioning groove 14 opened on the conical cylinder 4, a positioning rod 141 slidably connected in the positioning groove 14, and a fourth elastic element 142 provided between the inner wall of the positioning groove 14 and the positioning rod 141. A positioning hole 15 matching the positioning rod 141 is opened on the inner side wall of the annular housing 1, and a second inclined surface is opened on the lower side of the end of the positioning rod 141.

[0064] Specifically, during the installation of the LED spotlight, the positioning rod 141 is inserted into the positioning hole 15 to achieve the positioning installation of the annular housing 1 and the conical cylinder 4. It should be noted that the elastic stiffness of the fourth elastic element 142 is greater than the spring stiffness coefficient in the elastic telescopic tube 5. When the LED spotlight is removed, as the conical cylinder 4 moves outward from the annular housing 1, the positioning rod 141 is no longer abutted by the inner wall of the annular housing 1. The positioning rod 141 moves out of the positioning groove 14 under the pushing force of the fourth elastic element 142, and the positioning rod 141 abuts against the bottom wall of the panel 2 to limit the positions of the conical cylinder 4 and the annular housing 1, facilitating the staff to smoothly pick up the LED spotlight falling from the ceiling hole slot.

[0065] The present invention also discloses a usage method of an LED spotlight, including the following steps:

[0066] S1: When the LED spotlight is in use, thread the spotlight body 16 onto the pedestal 3, and the spotlight body 16 and the spotlight face cover are combined into one. At this time, the positioning rod 141 is placed below the panel 2, and then pass the spotlight body 16 through the LED spotlight hole slot reserved in the indoor ceiling until the spring clip 6 enters the indoor ceiling.

[0067] S2: Subsequently, the staff manually toggles the positioning rod 141, and the positioning rod 141 contracts into the positioning groove 14. The conical cylinder 4 is no longer restricted between the annular outer shell 1. The conical cylinder 4 moves upward under the pulling of the elastic telescopic tube 5. The conical cylinder 4 contracts into the annular outer shell 1 until the positioning rod 141 aligns with the positioning hole 15. The positioning rod 141 is inserted into the positioning hole 15 under the elastic push of the fourth elastic element 142 to position the conical cylinder 4 and the annular outer shell 1;

[0068] S3: After the conical cylinder 4 moves upward, the first pulling member 7 and the second pulling member 10 are no longer stressed. The main rod 6041 first resets and rotates under the action of the torsion spring 603. The rod body 8 slides outside the main rod 6041 under the pulling of the first elastic element 606. Finally, the reset swing rod 604 drives the abutting rod 605 to abut against the inner wall of the ceiling, so that the spotlight body 16 is fixed on the indoor ceiling through the spotlight face cover;

[0069] S4: When the LED spotlight needs to be disassembled, the staff places two fingers in the annular groove 401 of the conical cylinder 4 and uses other fingers to push up the panel 2. Then the fingers press down the conical cylinder 4, and the conical cylinder 4 moves downward relative to the annular outer shell 1, and the elastic telescopic tube 5 is stretched;

[0070] S5: When the conical cylinder 4 moves downward, both the first pulling member 7 and the second pulling member 10 are stressed. The pneumatic elastic telescopic members 11 of the first pulling member 7 and the second pulling member 10 are both stretched. The pneumatic elastic telescopic member 11 extracts the air in the cavity 131 of the sealing plug 13. The sealing plug 13 no longer expands, creating a gap between the rope body 12 and the sealing plug 13, facilitating the subsequent smooth pulling of the rope body 12;

[0071] S6: As the rope body 12 of the first pulling member 7 starts to be stressed, the rope body 12 of the first pulling member 7 exerts a pulling force on the plug rod 801. The plug rod 801 slides into the chute 802. The rod body 8 is no longer restricted between the main rod 6041. As the rope body 12 of the first pulling member 7 continues to be pulled, the rod body 8 slides relative to the main rod 6041, and the length of the swing rod 604 shortens and gradually moves away from the inner wall of the ceiling;

[0072] As the rope body 12 of the second pulling member 10 starts to be stressed, the rope body 12 of the second pulling member 10 pulls the main rod 6041, and the main rod 6041 is stressed and approaches the outer side wall of the annular outer shell 1;

[0073] S7: As the conical cylinder 4 moves outward relative to the annular outer shell 1, the positioning rod 141 is no longer abutted against the inner wall of the annular outer shell 1. The positioning rod 141 moves out of the positioning groove 14 under the elastic push of the fourth elastic element 142. The positioning rod 141 abuts against the bottom wall of the panel 2 to limit the positions of the conical cylinder 4 and the annular outer shell 1. At this time, the staff can smoothly pick up the LED spotlight falling from the ceiling hole groove.

[0074] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, making equivalent replacements or changes, shall be covered by the protection scope of the present invention.

10. A method for using the LED spot lamp according to claim 9, characterized in that, It includes the following steps: S1: When the LED spotlight is in use, thread the spotlight body (16) onto the pedestal (3). The spotlight body (16) and the spotlight face cover are combined into one. At this time, the positioning rod (141) is placed under the panel (2). Then, pass the spotlight body (16) through the LED spotlight hole groove reserved in the indoor ceiling until the spring clip (6) enters the indoor ceiling; S2: Then, the staff manually toggles the positioning rod (141). The positioning rod (141) contracts into the positioning groove (14). The restriction between the conical cylinder (4) and the annular housing (1) no longer exists. The conical cylinder (4) moves upward under the pulling of the elastic telescopic tube (5). The conical cylinder (4) contracts into the annular housing (1) until the positioning rod (141) is aligned with the positioning hole (15). The positioning rod (141) is inserted into the positioning hole (15) under the elastic push of the fourth elastic element (142) to position the conical cylinder (4) and the annular housing (1); S3: After the first pulling member (7) and the second pulling member (10) are no longer stressed when the conical cylinder (4) moves upward, the main rod (6041) takes the lead in resetting and rotating under the action of the torsion spring (603). The rod body (8) slides outside the main rod (6041) under the pulling of the first elastic element (606). Finally, the reset swing rod (604) drives the abutting rod (605) to abut against the inner wall of the ceiling, so that the spotlight body (16) is fixed on the indoor ceiling through the spotlight face cover; S4: When the LED spotlight needs to be disassembled, the staff place two fingers in the annular groove (401) of the conical cylinder (4) and push up the panel (2) with other fingers. Then, the fingers press down the conical cylinder (4), and the conical cylinder (4) moves downward relative to the annular housing (1), and the elastic telescopic tube (5) is stretched; S5: When the conical cylinder (4) moves downward, both the first pulling member (7) and the second pulling member (10) are stressed, and the pneumatic elastic telescopic members (11) of the first pulling member (7) and the second pulling member (10) are both stretched. The pneumatic elastic telescopic member (11) extracts the air in the cavity (131) of the sealing plug (13), and the sealing plug (13) no longer expands, creating a gap between the rope body (12) and the sealing plug (13), facilitating the subsequent smooth pulling of the rope body (12); S6: As the rope body (12) of the first pulling member (7) starts to be stressed, the rope body (12) of the first pulling member (7) exerts a pulling force on the plug rod (801), and the plug rod (801) slides into the chute (802). There is no longer a restriction between the rod body (8) and the main rod (6041). As the rope body (12) of the first pulling member (7) is continuously pulled, the rod body (8) slides relative to the main rod (6041), and the length of the swing rod (604) shortens and gradually moves away from the inner wall of the ceiling; As the rope body (12) of the second pulling member (10) starts to be stressed, the rope body (12) of the second pulling member (10) pulls the main rod (6041), and the main rod (6041) is stressed and approaches the outer wall of the annular housing (1); S7: As the conical cylinder (4) moves outward to the annular housing (1), the positioning rod (141) is no longer abutted against the inner wall of the annular housing (1). The positioning rod (141) moves out of the positioning groove (14) under the elastic push of the fourth elastic element (142), and the positioning rod (141) abuts against the bottom wall of the panel (2) to limit the position of the conical cylinder (4) and the annular housing (1). At this time, the staff can smoothly receive the LED spotlight falling from the ceiling hole slot.
