Fastener 342 is kept away from slider 34 one end and is handle portion 3422, and handle portion 3422 locates outside slider 34, and fixedly connected with extension spring 343, and the extension spring is kept away from fastener 342 one end fixed connection on slider 34. A block 3421 is disposed at the middle of one surface of the clip 342 close to the slider 34, an elastic clip 34211 is disposed at one end of the block 3421 away from the clip 342, and the clip 34211 is spherical and disposed in the groove 341. When the clip member 342 is rotated, the clip body 34211 can move up and down in the groove 341. The fixing member 33 is provided with a slot 332 adapted to the engaging member 34211 in the longitudinal direction, and the engaging member 34211 can enter the slot 332 when the handle 3422 rotates in a direction away from the sliding member 34. Because the card body 34211 is spherical for behind the card body 34211 entering draw-in groove 332, when the card body 34211 does not receive the external force that makes the card body 34211 leave draw-in groove 332, draw-in groove 332 can restrict the card body 34211 and leave, realizes fastener 342 and draw-in groove 332 joint, thereby realizes slider 34 and mounting 33 joint.

Referring to fig. 2, in order to reduce noise generated when the chain 32 rotates, a fixing piece 6 is fitted around the rotating shaft of the sprocket 31. The rotating shaft of the chain wheel 31 is provided with a nut 311 which is in threaded connection with the rotating shaft, one end of the fixing piece 6 is sleeved between the chain wheel 31 and the nut 311, the other end of the fixing piece is provided with a limiting groove 61, and the limiting groove 61 is clamped on the vertical rail 12. The nut 311 is screwed, and the chain wheel 31 and the nut 311 clamp the fixing piece 6, so that the chain wheel 31 is fixed on the sliding rail 1, the gear is kept in the forward direction, and noise generated when the chain 32 rotates is effectively reduced.

Referring to fig. 5, three noise dampers 7 are provided on the slide rail 1, and the noise dampers 7 are provided on the vertical rail 12. The noise reduction piece 7 comprises an insertion part 71, a bolt 72 is arranged on the noise reduction piece 7, and the middle part of the insertion part 71 is inserted into the vertical rail 12 and then fixed on the vertical rail 12 through the bolt 72. The two side surfaces of the insertion part 71 are vertically connected with bristles 73, extend to the area formed between the transverse rail 11 and the vertical rail 12 and are abutted against the chain 32. The chain 32 can sway in the rotating process, and the bristles 73 can support the chain 32 by arranging the bristles 73, so that the sway of the chain 32 is reduced. As shown in fig. 3, an L-shaped supporting block 35 is disposed in the middle of one side of the fixing member 33 opposite to the fixing portion 331, and one side of the supporting block 35 is connected to the fixing member 33 and the other side is bent away from the fixing member 33. The chain 32 is located between the support block 35 and the vertical rail 12 to prevent the chain 32 from sagging as it rotates. Under the effect of noise reduction part 7 and supporting shoe 35, make chain 32 can obtain the support at the rotation in-process, reduce chain 32 and rock to alleviate chain 32 and sprocket 31 interlock not tightly, lead to the situation that the noise increases.

Referring to fig. 1 and 2, in case of power failure, the motor 21 cannot be activated, so that the garage door 9 cannot be automatically opened or closed by the driving of the motor 21, and a user can manually open or close the garage door 9 by separating the sliding member 34 from the fixing member 33. Since the garage door motor is installed on the ceiling, in order to facilitate the user to rotate the latch 342 when power is off, as shown in fig. 4, a pull rope 8 is provided on the handle portion 3422. The user simply pulls the pull cord 8 to rotate the handle portion 3422 away from the sliding member 34, thereby separating the sliding member 34 from the fixed member 33 and lifting the garage door 9.

The implementation principle of the embodiment is as follows: the motor 21 is activated, the motor 21 drives the sprocket 31 to rotate, the sprocket 31 rotates to rotate the chain 32, the chain 32 rotates to slide the fixing member 33, so as to slide the sliding member 34, and further to move the connecting rod 5, and further to move the garage door 9, so as to raise or lower the garage door 9, thereby opening or closing the garage door 9.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
