Assemblies, when the pulley 8 protrudes from the inner cavity of the door body 2, and the bottom end of the pulley 8 touches the upper surface of the guide rail 4, the operator can move the door body 2, and when the pulley 8 fully extends into the inner cavity of the door body 2, At this time, the end of the door body 2 with the pulley 8 moved down, so that the bottom surface of the door body 2 is in a horizontal state, and the bottom surface of the door body 2 is in contact with the elastic rubber pad 7, and the elastic rubber pad 7 has a good shock absorption effect. Make the pulley 8 stretch into the inner cavity, the door body 2 moves down, and the lower surface of the door body 2 contacts with the elastic rubber pad 7, so as to reduce the impact of the door body 2 on the bottom plate 3.

Referring to Fig. 1 and Fig. 2, the drive assembly includes a worm gear 12 and a worm 11 meshingly connected, the inner cavity of the door body 2 is connected with a rotating shaft 13 along the horizontal direction, the worm gear 12 is fixedly sleeved on the rotating shaft 13, and at the same time, it is connected with the worm gear The worm 11 engaged with 12 is rotatably carried in the inner cavity of the door body 2, and is vertically arranged. At the same time, the rotating shaft 13 is also fixedly connected with the installation part 14 for installing the pulley 8. The installation part 14 is coaxially arranged with the worm wheel 12, so that the worm The rotation of 11 drives the worm wheel 12 to rotate, and then the rotation of the rotating shaft 13 drives the pulley 8 to swing, so that the position of the pulley 8 is changed conveniently and quickly, so that the pulley 8 can extend into or out of the inner cavity of the door body 2, thereby realizing the movement of the door body 2 and fixed; at the same time, using the self-locking property of the worm gear 12 and the worm 11, that is, only the worm gear 11 can drive the worm gear 12 to move, and the worm gear 12 cannot drive the worm gear 11 to move, so that the pulley 8 will not be dislodged due to the effect of gravity after the position is adjusted. To decline, reached the effect of positioning pulley 8.

Simultaneously, the wheel center of the pulley 8 is rotatably connected with a connecting shaft, the connecting shaft is arranged horizontally, and the two ends of the connecting shaft are fixedly connected with the installation part 14 respectively by bolts, and the detachable pulley 8 is realized by means of bolted connection, which improves The service life of the door body 2 as a whole; at the same time, as a relatively conventional connection method, the bolt connection has a simple structure and a firm connection.

Referring to Figure 1 and Figure 2, in order to better adjust the position of the pulley 8 conveniently, the door body 2 is connected with a handle 6 rotating along the horizontal plane, and one end of the handle 6 extending into the inner cavity of the door body 2 is integrally formed with a rotating shaft 9, which rotates A pair of bevel gears 10 meshing with each other is installed between the shaft 9 and the worm 11. The pair of bevel gears 10 are arranged coaxially with the rotating shaft 9 and the worm 11 respectively. The pair of bevel gears 10 change the transmission direction of the power so that the operator can Carrying out the rotation operation of the handle 6 in the horizontal direction will make the operation more convenient.

In addition, the door body 2 is equipped with a connecting rod 15, a cross bar 17, a slider 16, a first limit block 18 and a second limit block 19, and the first limit block 18 and the second limit block 19 are all welded on the door. On the same inner side wall of the body 2, the elongated cross bar 17 is fixedly connected between the first limiting block 18 and the second limiting block 19, the slider 16 slides on the cross bar 17, and one end of the connecting rod 15 It is rotatably connected with the mounting part 14 , and the other end is rotatably connected with the slider 16 .

When the slider 16 slides and abuts against the first stopper 18, the pulley 8 protrudes from the inner cavity of the door body 2 and the bottom end of the pulley 8 touches against the upper surface of the guide rail 4. At this time, the operator can move the door body 2; when the slider 16 slides and abuts against the second limit block 19, the pulley 8 fully extends into the inner cavity of the door body 2, and at this time, the end of the door body 2 equipped with the pulley 8 moves down, so that the door The bottom surface of the body 2 is in a horizontal state, the lower surface of the door body 2 abuts against the elastic rubber pad 7, and the door body 2 is fixed. Using the collision between the slider 16 and the two limit blocks, it is convenient and quick to judge whether the pulley 8 is fully inserted into the inner cavity of the door body 2 or whether the bottom end of the pulley 8 is in contact with the upper surface of the guide rail 4, without visually observing the pulley 8.
