[0002] The inverted fast rolling door has the characteristics of fast lifting, safety, reliability and beauty. It is generally used in slaughterhouse assembly lines, automobile manufacturing assembly lines, etc. It can ensure a good production environment and minimize air convection.

[0003] The existing inverted rolling shutter doors still have the following problems during use: the ordinary fast rolling shutter doors on the market have a horizontal door head restriction on the top, which makes it impossible for the lifting assembly line device to pass normally. At this time, the inverted rolling shutter doors cannot meet the use requirements and may also cause obstacles, affecting production and life.

[0004] Therefore, it is necessary to invent a kind of inverted fast rolling door to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide an inverted fast rolling shutter door to solve the problem raised in the above background technology that the ordinary fast rolling shutter doors on the market are unable to pass normally due to the horizontal door head restriction at the top, and the inverted rolling shutter door at this time cannot meet the use requirements and may also cause obstacles, affecting production and life.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: an inverted fast rolling shutter door, comprising a storage box, a cavity one is reserved inside the storage box, and the cavity one is connected to the groove reserved at the top of the storage box, the outer wall of the storage box is fixedly connected to a motor, and the output shaft of the motor is transmission-connected to a driving shaft, and a rolling shutter piece is wrapped around the outer wall of the driving shaft, and the rolling shutter piece passes through the groove to facilitate the winding and unwinding of the rolling shutter piece, the top of the rolling shutter piece is fixedly connected to a top rod, and side blocks are fixedly connected to the top two sides of the storage box, and a cavity two is reserved inside the side blocks, and also includes:

[0007] The reverse pulling assembly has a lifting rope fixedly connected to the end of the push rod, and the lifting rope is transmission-connected to the fixed pulley and the movable pulley, and the other end of the lifting rope is fixedly connected to the second inner wall of the cavity, and the lower end of the movable pulley is fixedly connected to a counterweight.

[0008] Preferably, bristles are fixedly connected to the inner walls on both sides of the groove, and the bristles on each side are in contact with the surface of the rolling shutter piece. The bristles fill the gap between the rolling shutter piece and the groove to prevent impurities from entering the cavity through the groove and affecting the subsequent retraction and extension of the rolling shutter piece.

[0009] Preferably, the end of the driving shaft is rotatably connected to an inner wall of the cavity via a bearing, thereby ensuring the stability of the rolling and unwinding movement of the rolling shutter sheet driven by the driving shaft.

[0010] Preferably, the suspension rope is passed through the outer ring of the fixed pulley and the movable pulley in an "S" shape, and the length of the suspension rope remains unchanged, and the stable movement of the suspension rope is ensured by the fixed pulley and the movable pulley.

[0012] Preferably, the weight of the counterweight block is heavier than the total weight of the rolling shutter piece, and the counterweight block slides up and down in contact with the inner wall of cavity two. When the rolling shutter piece is rolled up, the counterweight block is in a high position and in a pulled-down state. When the fast rolling shutter door needs to be closed, the motor is started to rotate in the opposite direction. Since the counterweight block is always in a pulled-down state, the rolling shutter piece will be pulled upward to achieve the effect of closing the door.

[0013] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0014] The utility model drives the driving shaft to rotate by starting the motor, thereby facilitating the winding and unwinding of the rolling shutter piece. At the same time, when the rolling shutter piece is wound up, the top rod moves downward to drive the movement of the hanging rope. At this time, the counterweight block connected to the bottom of the movable pulley housing will rise upward according to the proportion of the winding of the rolling shutter piece. Similarly, when the rolling shutter piece is unrolled, the counterweight block is always in a pulled-down state. At this time, the rolling shutter piece will be pulled up, and the counterweight block will drop downward at the same time, thereby achieving the effect of fast door closing. There is no lintel and door head above the door opening of the fast rolling shutter door. After opening, there is no obstacle above, which is convenient for the hanging assembly line to pass.

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model provides Figure 1-6 The inverted fast rolling shutter door shown includes a storage box 1, a cavity 2 is reserved inside the storage box 1, and the cavity 2 is connected to the groove 3 reserved at the top of the storage box 1, the outer wall of the storage box 1 is fixedly connected to a motor 6, and the output shaft of the motor 6 is drivingly connected to a drive shaft 7, and a rolling shutter piece 8 is wrapped around the outer wall of the drive shaft 7, and the rolling shutter piece 8 passes through the groove 3 to facilitate the winding and unwinding of the rolling shutter piece 8, and the top of the rolling shutter piece 8 is fixedly connected to a push rod 9, and the two sides of the top of the storage box 1 are fixedly connected to side blocks 4, and a cavity 2 5 is reserved inside the side blocks 4, and also includes:

[0026] The back-pulling assembly 10 has a lifting rope 101 fixedly connected to the end of the top rod 9, and the lifting rope 101 is transmission-connected to a fixed pulley 102 and a movable pulley 103, and the other end of the lifting rope 101 is fixedly connected to the inner wall of the cavity 2 5, and a counterweight 104 is fixedly connected to the lower end of the movable pulley 103.

[0027] Brushes are fixedly connected to the inner walls on both sides of the groove 3, and the bristles on each side are in contact with the surface of the rolling shutter piece 8. The bristles fill the gap between the rolling shutter piece 8 and the groove 3 to prevent impurities from entering the cavity 2 through the groove 3 and affecting the subsequent retraction and extension of the rolling shutter piece 8.

[0028] The end of the driving shaft 7 is rotatably connected to the inner wall of the cavity 2 through a bearing, thereby ensuring the stability of the rolling and unwinding movement of the rolling shutter piece 8 driven by the driving shaft 7.

[0029] The suspension rope 101 passes through the outer rings of the fixed pulley 102 and the movable pulley 103 in an "S" shape, and the length of the suspension rope 101 remains unchanged. The fixed pulley 102 and the movable pulley 103 ensure stable movement of the suspension rope 101.

[0030] The fixed pulley 102 and the movable pulley 103 are both located inside the cavity 2 5, and the fixed pulley 102 is fixedly connected to the top wall of the cavity 2 5, and the fixed pulley 102 is arranged in parallel with the movable pulley 103, and the movable pulley 103 is always located at the lower position of the fixed pulley 102. The suspension rope 101 ensures the stability of its own operation through the fixed pulley 102 and the movable pulley 103, and at the same time facilitates the lifting and lowering movement of the counterweight block 104 through the movable pulley 103.

[0031] The weight of the counterweight 104 is heavier than the total weight of the rolling shutter piece 8, so it is convenient for the counterweight 104 to drive the rolling shutter piece 8 to move, and the counterweight 104 slides up and down in contact with the inner wall of the cavity 2 5 to ensure the stability of the movement of the counterweight 104 and the movable pulley 103. When the rolling shutter piece 8 is rolled up, the counterweight 104 is in a high position and in a pull-down state. When the fast rolling shutter door needs to be closed, the starter motor 6 rotates in the opposite direction. Since the counterweight 104 is always in a pull-down state, the rolling shutter piece 8 will be pulled upward to achieve the effect of closing the door.

[0032] Working principle: when using an inverted fast rolling shutter door, first start the motor 6 to drive the drive shaft 7 connected to the output shaft of the motor 6 to rotate, so as to facilitate the winding and unwinding of the rolling shutter piece 8. The motor 6 drives the drive shaft 7 to rotate to wind up the rolling shutter piece 8. At this time, the top rod 9 of the rolling shutter piece 8 moves downward to drive the suspension rope 101 fixedly connected to the top rod 9 to move, and the movable pulley 103 starts to rise. At this time, the counterweight block 104 will rise upward in sync with the inner wall of the cavity 2 5 according to the proportion of the rolling shutter piece 8 being retracted. At this time, the fast rolling shutter door is opened, the rear motor 6 stops rotating, the motor 6 is braked and locked, and the counterweight block 104 is always in a pulled-down state (see Figure 2 and 4 ), at this time, the hoisting assembly line can pass normally from above the fast rolling door;

[0033] The motor 6 rotates in the opposite direction, and the brake lock is opened. Similarly, since the counterweight block 104 is always in the pulled-down state, the shutter piece 8 will be pulled up at this time, and the counterweight block 104 will fall down in contact with the inner wall of the cavity 2 5 at the same time. After the fast rolling shutter door is closed in place, the brake lock of the motor 6 is locked, thereby achieving the effect of fast door closing (refer to Figure 1 , 5 and 6), the fast rolling shutter door has no lintel and door head above the door opening, and there is no obstacle above after opening (see Figure 2 ), which is convenient for the hanging assembly line to pass through, and is specially designed for the hanging assembly line;

[0034] At the same time, when the rolling shutter piece 8 is rolled up into the storage box 1, the outer surface of the rolling shutter piece 8 passes through the bristles fixedly connected to the inner wall of the groove 3. The bristles clean the surface of the rolling shutter piece 8 appropriately to prevent impurities from entering the cavity 2 inside the storage box 1 as the rolling shutter piece 8 moves and affecting the subsequent use of the rolling shutter piece 8, thereby extending the service life of the entire rolling shutter piece 8.

[0035] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
