[0024] Embodiment:

[0025] Refer to Figures 1-6, an embodiment of the present utility model provides an electric curtain, which includes an electric track 1 with a slider 4, a connecting rod 7, and a curtain cloth 5. A plurality of hanging rings 6 are fixedly connected to the top of the curtain cloth 5. The number of the hanging rings 6 is 5 - 10. The hanging rings 6 are sleeved on the connecting rod 7. The connecting rod 7 is slidably installed below the electric track 1. It further includes: a first wedge block 201, fixedly connected to the top of one of the hanging rings 6. The first wedge block 201 and the hanging ring 6 it is connected to are fixedly connected by screws; an installation groove 202 is opened at the bottom of the slider 4. The first wedge block 201 is inserted into the inner wall of the installation groove 202. Among them, a driving part for driving the first wedge block 201 to move out of the installation groove 202 is provided on the slider 4. By controlling the slider 4 to slide on the electric track 1, the movement of the curtain cloth 5 is controlled.

[0026] Specifically, by driving the first wedge block 201 to move out of the installation groove 202 at the bottom of the slider 4, the descending first wedge block 201 drives the connecting rod 7 to slide down, and the hanging ring 6 can be removed from the connecting rod 7 to disassemble the curtain cloth 5. During installation, just operate in the reverse direction, which is convenient for replacing the curtain cloth 5 by oneself, saves time, and reduces the replacement cost.

[0027] The driving part includes a limiting groove 203 opened on the first wedge block 201. A connecting rod 207 is slidably installed on the slider 4. One end of the connecting rod 207 away from the slider 4 is fixedly connected with a protrusion 208. The other end of the connecting rod 207 is fixedly connected with a second wedge block 205. Among them, the second wedge block 205 is inserted into the inner wall of the limiting groove 203. A chute 204 is opened inside the second wedge block 205. The second wedge block 205 is slidably connected to the inner wall of the chute 204.

[0028] Specifically, pull the protrusion 208 outwards. The protrusion 208 drives the second wedge block 205 to slide into the chute 204 and move out of the limiting groove 203 through the connecting rod 207, so as to release the limit on the first wedge block 201. The first wedge block 201 falls from the installation groove 202 under the action of gravity.

[0029] A spring 206 is fixedly connected between the inner wall of the second wedge block 205 and the chute 204. The inclined surface of the second wedge block 205 faces the inclined surface of the first wedge block 201.

[0030] Specifically, during installation, insert the first wedge block 201 into the installation groove 202. The first wedge block 201 pushes the second wedge block 205 to slide into the chute 204 and compress the spring 206. After the first wedge block 201 is completely inserted, the spring 206 resets so that the second wedge block 205 is inserted into the limiting groove 203.

[0031] Two symmetrically arranged baffles 8 are fixedly connected to the bottom of the electric track 1. Sliding grooves 9 are formed on the opposite surfaces of the two baffles 8. The connecting rod 7 is slidably installed in the sliding grooves 9. Through holes 10 are formed in the baffles 8. The diameter of the through holes 10 is larger than the diameter of the hanging rings 6. Channels 11 are formed at the bottoms of the baffles 8. The channels 11 communicate with the through holes 10. The width of the channels 11 is larger than the width of the curtain cloth 5, and the width of the channels 11 is smaller than the diameter of the connecting rod 7. By providing the sliding grooves 9, when the first wedge-shaped block 201 drops, it will drive the connecting rod 7 to drop along the sliding grooves 9, and ensure that during normal use, the connecting rod 7 will not move towards the two ends of the baffle 8.

[0032] Specifically, after the first wedge-shaped block 201 drives the connecting rod 7 to descend, the connecting rod 7 falls into the through hole 10. Since the width of the channel 11 is smaller than the diameter of the connecting rod 7, the connecting rod 7 will not fall off the baffle 8. Then, when the curtain cloth 5 is pulled, the hanging rings 6 and the curtain cloth 5 will respectively move out from the through hole 10 and the channel 11.

[0033] A housing 301 is arranged above the electric track 1. A motor 302 is fixedly connected to the outer wall of the housing 301. The output end of the motor 302 is fixedly connected to a bidirectional lead screw 303. The bidirectional lead screw 303 is rotatably connected to the housing 301 through a bearing. Among them, two symmetrically arranged sliding blocks 304 are threadedly connected to the bidirectional lead screw 303. The sliding blocks 304 are slidably connected to the inner wall of the housing 301. A support rod 305 is rotatably connected between the sliding blocks 304 and the electric track 1. A limiting rod 306 is fixedly connected to the bottom of the housing 301. The electric track 1 and the baffle 8 are both slidably connected to the limiting rod 306. The motor 302 is electrically connected to an external power source.

[0034] Specifically, when the motor 302 is started, the output end of the motor 302 drives the bidirectional lead screw 303 to rotate, causing the sliding blocks 304 to slide horizontally along the housing 301 and drive the support rod 305 to rotate. The support rod 305 drives the electric track 1 to slide longitudinally along the limiting rod 306, so as to adjust the height of the curtain cloth 5. When replacing the curtain cloth 5, it can be lowered, eliminating the need to climb heights, which is more convenient and safer.

[0035] The above is only a preferred specific embodiment 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 and the inventive concept of the present invention, makes equivalent replacements or changes, and all should be covered within the protection scope of the present invention.
