[0085] The brake block is provided with a second driving groove 404 for the transverse slide bar 31 to pass through, and the door body is provided with a driving module 221 located between the handle and the longitudinal slide bar.

[0086] In this embodiment, the second driving groove 34 is formed on the transverse sliding rod 31 and is longitudinally penetrated and allows the driving protrusion 32 to move.

[0087] In this embodiment: the transverse sliding bar 31 includes:

[0106] refer to Figure 1-5 , the principle of this embodiment is:

[0107] The principle of this embodiment is that when the handle rotates, the sector block is driven to rotate and the card block leaves the card slot. Then, the drive slide shaft is controlled to move by the third return spring and the columnar drive part moves to the right (by Figure 2For example), the longitudinal slide bar is then controlled to rise by the first return spring, which then drives the inclined protrusion to rise, and the transverse slide bar is controlled to move left by the second return spring, thereby making the driving protrusion move. When the driving protrusion leaves the second driving groove, the brake block is controlled to rise by the third return spring and separated from the door frame, thereby realizing the sliding of the door body.

[0108] During braking, the handle rotates and causes the sector block to rotate, so that the card block enters the card slot to fix the sector block. The columnar driving part is controlled to move by the sector block and drives the transverse sliding bar to move through the longitudinal sliding bar, so that the driving protrusion enters the second driving slot and causes the braking body to descend. When the braking body contacts the door frame, the braking of the door body is completed.

[0109] Embodiment 2 is different from Embodiment 1 in that:

[0110] like Figure 6-8 As shown, in this embodiment: the pulley structure includes:

[0111] The slide 60 is fixedly connected to the door body;

[0113] The electromagnetic structure is installed between the first pulley 61 and the second pulley 62, and can control the first pulley 61 and the second pulley 62 to move closer to or farther from each other;

[0114] The guide rails are composed of a first guide rail 61a and a second guide rail 62a which are spaced apart and correspond to the first pulley 61 or the second pulley 62, and a brake groove 63 for the brake body to move is formed between the first guide rail 61a and the second guide rail 62a.

[0115] In this embodiment: the electromagnetic structure includes:

[0116] The housing 70 is fixedly connected to the slide 60 and has an electromagnet 71 installed therein;

[0117] Electromagnetic chambers 72 are formed on both sides of the housing 70;

[0118] The support shaft 73 is connected to the bottom of the electromagnetic cavity 72 through the fourth return spring 74, and one end of the support shaft 73 passes through the electromagnetic cavity 72;

[0119] One end of the support shaft 73 is connected to the first pulley 61 or the second pulley 62 via a rotating shaft 74 .

[0120] In this embodiment: a cleaning structure is provided on the side of the brake body away from the door body, and the cleaning structure includes:

[0121] The limiting rod 80 is fixedly connected to the bottom of the brake body and extends laterally, and is located between the first pulley 61 and the second pulley 62;

[0122] A dust suction chamber 81 is formed on the limiting rod 80;

[0123] The dust suction port 82 is provided on the limiting rod 80 and communicates with the dust suction chamber 81;

[0129] refer to Figure 6-8 The principle of this embodiment is that when braking, the brake body descends and makes the limit rod abut against the bottom of the brake groove to complete the braking. When cleaning the pulley, first control the electromagnet to energize, and attract the first pulley and the second pulley to approach the shell and above the cleaning wheel, and use the dust suction pump to connect with the air pump interface. When vacuuming, impurities enter from the dust suction port and pass through the impeller, and then are discharged through the dust suction chamber. When the airflow passes through the impeller, it drives the impeller to rotate and drives the cleaning wheel to rotate. The cleaning brush on the cleaning wheel is used to brush the pulley to complete the cleaning.

[0130] When the door moves, the electromagnet is de-energized, the pulley is controlled by the fourth return spring to contact the guide rail again, the limit rod is controlled to rise by the brake body, and is located between the first pulley and the second pulley. When the door moves, the guide rail is cleaned through the dust suction port. At the same time, the limit rod between the first pulley and the second pulley can also prevent the pulley from separating from the guide rail, thereby ensuring smooth movement of the door.

[0131] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
