[0030] In actual use of an existing industrial lifting door, when adjusting the height of the lifting door body, the lifting door body has a limited upward and downward movement range within the door opening opened in the wall, and cannot utilize the entire area of ​​the door opening, which may lead to insufficient space utilization and affect the size and quantity of items stored or passing through the door opening. Therefore, this problem is solved by increasing the upward and downward movable range of the lifting door.

[0031] like Figures 1 to 5 The utility model provides a lifting door with adjustable lifting height.

[0032] Specifically, by Figure 1-4 A lifting door with adjustable lifting height is provided, comprising a wall 1, a door panel 3 and a lifting assembly 2, wherein the wall 1 is provided with a door opening, the door panel 3 is located at one side of the door opening and is used for closing the door opening, the lifting assembly 2 is located between the wall 1 and the door panel 3 and is used for controlling the lifting of the door panel 3, the lifting assembly 2 comprises two racks 201 connected to the outer wall of the door panel 3, a fixed plate 202 is provided at one side of the door panel 3, a bidirectional motor 205 is installed on the top of the fixed plate 202, both driving ends of the bidirectional motor 205 are connected to connecting rods 203, and a gear 204 meshing with the rack 201 is installed at one end of the connecting rod 203 away from the bidirectional motor 205.

[0033] In the utility model, when the door panel 3 needs to be raised or lowered, the two connecting rods 203 are driven to rotate simultaneously by the bidirectional motor 205, and the connecting rods 203 drive the gear 204 to rotate, and the rotating gear 204 drives the rack 201 to slide along the outer wall of the wall 1, and the door panel 3 is connected to the rack 201, so that the rack 201 drives the door panel 3 to move up and down together when moving;

[0034] The door opening can be closed conveniently by controlling the lifting of the door panel 3. At the same time, the fixed plate 202, the connecting rod 203, the gear 204 and the bidirectional motor 205 are all located above the door opening. Therefore, when the bottom of the upwardly moving rack 201 reaches the position of the gear 204, the door panel 3 is already completely above the door opening. At this time, the door opening has been fully displayed, so that the entire area of ​​the door opening can be utilized.

[0035] Furthermore, as a specific implementation of the present invention, the present invention provides a lifting door with adjustable lifting height.

[0036] Specifically, Figure 1 and 5 It is shown that a support block 8 is installed at the bottom of the rack 201, two support plates 15 are installed at the bottom of the wall 1, a damper 9 is installed on the top of the support plate 15, a circular partition 10 is installed on the top of the damper 9, and the circular partition 10 corresponds to the support block 8.

[0037] In the present invention, when the door panel 3 falls rapidly, the rack 201 first falls above the circular partition 10 through the support block 8. The rack 201 and the support block 8 will squeeze the circular partition 10 toward the damper 9 due to inertia and gravity. When the damper 9 is squeezed, the damper 9 will absorb the kinetic energy brought by the rack 201 through its internal damping material or mechanism, thereby reducing its falling speed.

[0038] When the door panel 3 and the rack 201 touch the ground after falling, noise will be generated. The damper 9 can buffer the rack 201 and the door panel 3 and reduce the noise at the same time. The contact area between the rack 201 and the damper 9 is increased by the support block 8 and the circular partition 10, so that the rack 201 and the damper 9 are more stable when they contact each other. The rack 201 is shorter than the door panel 3. Therefore, when the support block 8 hits the circular partition 10 and squeezes the damper 9 downward for a certain distance, the door panel 3 can just hit the ground to avoid incomplete closure of the door opening.

[0039] Furthermore, as another specific implementation of the present invention, the present invention provides a lifting door with adjustable lifting height.

[0040] Specifically, Figure 1-5 It is shown that the wall 1 is provided with two slide rails 11 , one side of the rack 201 is connected with a ball bearing 12 adapted to the slide rail 11 , the ball bearing 12 is located inside the slide rail 11 and is slidably connected to the slide rail 11 , and the door panel 3 is located between the two slide rails 11 .

[0041] In the utility model, when the rack 201 moves up and down along the outer wall of the wall 1, the ball 12 slides along the slide rail 11, so that the rack 201 moves more smoothly. At the same time, the sliding of the ball 12 and the slide rail 11 also prevents the rack 201 from directly contacting the wall 1 and causing wear.

[0042] Furthermore, as another specific implementation of the present invention, the present invention provides a lifting door with adjustable lifting height.

[0043] Specifically, Figure 1 It is given that two connecting blocks 6 are installed on the outer wall of the wall 1, and a support rod 7 is connected between the two connecting blocks 6. The door panel 3 and the rack 201 are located between the wall 1 and the support rod 7. The connecting blocks 6 and the support rod 7 are located above the door opening, and the door panel 3 and the rack 201 are not in contact with the support rod 7.

[0044] In the utility model, when the position of the door panel 3 is completely moved to the top of the door opening, in order to prevent the door panel 3 and the rack 201 from falling due to unstable center of gravity, one side of the door panel 3 is protected by the support rod 7 to prevent the door panel 3 from tilting and falling, and the support rod 7 is not in direct contact with the door panel 3 and the rack 201 to prevent the support rod 7 from affecting the movement of the door panel 3 and the rack 201.

[0045] Furthermore, as another specific implementation of the present invention, the present invention provides a lifting door with adjustable lifting height.

[0046] Specifically, Figure 1-3 It is shown that two mounting blocks 13 are installed on the top of the fixed plate 202, the connecting rod 203 is plugged into the mounting blocks 13, a protective frame 14 is installed on the top of the fixed plate 202, the bidirectional motor 205 is located inside the protective frame 14, and the two connecting rods 203 are rotatably connected to the protective frame 14.

[0047] In the utility model, the positions of the two connecting rods 203 are fixed respectively by two mounting blocks 13, so that the connecting rods 203 are stabilized on the top of the fixing plate 202, and at the same time, the connecting rods 203 are plugged into the mounting blocks 13, so that the mounting blocks 13 will not affect the rotation function of the connecting rods 203 while fixing the connecting rods 203, and the protective frame 14 forms a closed space for the bidirectional motor 205 to protect the bidirectional motor 205 from being affected by the external environment and to improve the service life of the bidirectional motor 205.

[0048] Furthermore, as another specific implementation of the present invention, the present invention provides a lifting door with adjustable lifting height.

[0049] Specifically, Figure 1-2It is shown that two connecting plates 5 are installed on the outer wall of the wall 1, and a fixing block 4 is installed on the outer wall of the connecting plate 5. The fixing plate 202 is located between the two fixing blocks 4 and connected to the outer wall of the fixing block 4. A plurality of bolts are threadedly connected between the connecting plate 5 and the wall 1.

[0050] In the utility model, the connecting plate 5 is fixed to the outer wall of the wall 1 by multiple bolts to make the fixing block 4 more stable. The fixing block 4 fixes the two ends of the fixing plate 202, so that the fixing plate 202 is stabilized on one side of the wall 1 and the door panel 3, which is convenient for the fixing plate 202 to fix the mounting block 13 and the bidirectional motor 205. At the same time, the fixing plate 202 does not contact the door panel 3 to avoid affecting the movement of the door panel 3.

[0051] Working principle:

[0052] When the door panel 3 needs to be raised or lowered, the two connecting rods 203 are driven to rotate simultaneously by the bidirectional motor 205, and the connecting rods 203 drive the gear 204 to rotate, and the rotating gear 204 drives the rack 201 to slide along the outer wall of the wall 1, and the door panel 3 is connected to the rack 201, so that the rack 201 drives the door panel 3 to move up and down together when moving;

[0053] The door opening can be closed conveniently by controlling the lifting of the door panel 3. At the same time, the fixed plate 202, the connecting rod 203, the gear 204 and the bidirectional motor 205 are all located above the door opening. Therefore, when the bottom of the upwardly moving rack 201 reaches the position of the gear 204, the door panel 3 is already completely above the door opening. At this time, the door opening has been fully displayed, so that the entire area of ​​the door opening can be utilized.

[0054] When the door panel 3 falls rapidly, the rack 201 first falls above the circular partition 10 through the support block 8. The rack 201 and the support block 8 will squeeze the circular partition 10 toward the damper 9 due to inertia and gravity. When the damper 9 is squeezed, the damper 9 will absorb the kinetic energy brought by the rack 201 through its internal damping material or mechanism, thereby reducing its falling speed.

[0055] When the door panel 3 and the rack 201 touch the ground after falling, noise will be generated. The damper 9 can buffer the rack 201 and the door panel 3 and reduce the noise at the same time. The contact area between the rack 201 and the damper 9 is increased by the support block 8 and the circular partition 10, so that the rack 201 and the damper 9 are more stable when they contact each other. The rack 201 is shorter than the door panel 3. Therefore, when the support block 8 hits the circular partition 10 and squeezes the damper 9 downward for a certain distance, the door panel 3 can just hit the ground to avoid incomplete closure of the door opening.

[0056] The above is only a preferred embodiment of the present invention, and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes using the technical content suggested above without departing from the scope of the technical solution of the present invention.
