Description

Technical Field

[0001] This utility model belongs to the field of high-speed door technology, specifically relating to an L-shaped door with an upper-mounted transmission. Background Technology

[0002] L-shaped doors are door mechanisms used in workshops, laboratories, and other similar locations to partition off a localized space for equipment. An L-shaped door includes an L-shaped guide rail mounted on a frame, with a rollable door body fitted onto the guide rail. The door body comprises multiple hinged rigid door panels, with sealing strips locking between adjacent panels. A turbine guide rail is located at one horizontal end of the L-shaped guide rail for rolling the door body. A chain drive mechanism is mounted on the frame. When opening, the chain drive mechanism moves the door body along the L-shaped guide rail, causing it to roll along the turbine guide rail; when closing, the chain drive mechanism moves the door body along the L-shaped guide rail, causing it to retract from the turbine guide rail.

[0003] However, in existing L-shaped doors, the inlet and outlet of the turbine guide rail 3 are located at the bottom and connected to the horizontal end of the L-shaped guide rail. The door body has different bending directions at the bends of the L-shaped column and at the bends of the turbine guide rail, such as... Figure 1 As shown, when the door opens, door 1 bends counterclockwise at the bend of L-shaped guide rail 2 and clockwise at the inlet and outlet of turbine guide rail 3; when closing, door 1 bends counterclockwise at the inlet and outlet of turbine guide rail 3 and clockwise at the bend of L-shaped guide rail 2. This bending in different directions causes the sealing strips between the rigid door panels to bend and deform repeatedly in different directions, easily leading to cracks and damage to the sealing strips.

[0004] Based on this, this application provides an L-shaped door with an upper drive, so that the bending direction of the door body at the bend of the L-shaped guide rail and the bend of the inlet and outlet turbine guide rail is the same, so that the sealing strip will bend and deform in the same direction when passing through these two points, reducing the probability of cracking and damage caused by repeated bending and deformation in different directions.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Example 1: like Figures 2-3 As shown, an L-shaped door with an upper drive includes a frame 4 and a door body 1. The door body 1 includes several rigid door panels that are hinged together, and a sealing strip 5 is snapped between adjacent rigid door panels. The frame 4 is provided with two parallel L-shaped guide rails 2, and the frame 4 at the horizontal end of the L-shaped guide rails 2 is provided with symmetrical turbine guide rails 3. The two sides of the door 1 are fitted into the corresponding L-shaped guide rails 2, and the door 1 can enter or exit the turbine guide rails 3. The inlet and outlet of the turbine guide rail 3 are located at the top, and the horizontal end of the L-shaped guide rail 2 is smoothly connected to the inlet and outlet of the turbine guide rail 3. When opening the door, the door body 1 enters the turbine guide rail 3 in the horizontal direction and then bends downward to roll around. When closing the door, the door body 1 is pulled upward along the turbine guide rail 3 and then exits the turbine guide rail 3 in the horizontal direction. The frame 4 is equipped with a chain drive mechanism for driving the door 1 to move.

[0026] Preferably, the rigid door panel is provided with hinge plates 11 at both ends, and the hinge plates 11 of adjacent rigid door panels are hinged together by hinge shafts 12.

[0027] Preferred, such as Figure 4 As shown, the hinge shaft 12 is coaxially rotatably fitted with a hinge wheel 13 at its end, and the L-shaped guide rail 2 is provided with a guide rail groove 21 that rolls with the hinge wheel 13. The hinge wheels 13 at both ends of the door 1 can roll into or out of the turbine guide rail 3.

[0028] In the top-driven L-shaped door of Embodiment 1, when opening, the door body 1 bends counterclockwise at the bend of the L-shaped guide rail 2 and at the inlet and outlet of the turbine guide rail 3; when closing, the door body 1 bends clockwise at the inlet and outlet of the turbine guide rail 3 and at the bend of the L-shaped guide rail 2. Therefore, in the top-driven L-shaped door of this application, the door body 1 bends in the same direction at the bend of the L-shaped guide rail 2 and at the bend of the turbine guide rail 3, thus causing the sealing strip 5 to bend in the same direction when passing through these two points, reducing the probability of cracking and damage caused by repeated bending deformation in different directions.

[0029] Example 2: Based on Embodiment 1, the chain drive mechanism includes two sets of sprockets respectively set on both sides of the width of the door body 1. The sprocket set includes a main sprocket 61, a driven sprocket 62, and a bending auxiliary wheel mechanism. like Figure 5 As shown, the main sprocket 61 is mounted on the frame 4 at the horizontal end of the L-shaped guide rail 2, the driven sprocket 62 is mounted on the frame 4 at the vertical end of the L-shaped guide rail 2, and the bending auxiliary wheel mechanism is mounted on the frame 4 at the bend of the L-shaped guide rail 2. In the same set of sprockets, the main sprocket 61, the driven sprocket 62, and the bending auxiliary wheel mechanism are connected by a chain 63, which is fixedly connected to the width side of the door body 1. The main sprockets 61 in the two sprocket sets are connected by a drive mechanism.

[0030] Among them, the main sprocket 61 extends from the central axis of the sprocket 62 along the width direction of the door body 1.

[0031] Preferably, the drive mechanism includes a drive motor 6 mounted on the frame 4, and a transmission shaft 64 is coaxially fixedly mounted on the output end of the drive motor 6. The transmission shaft 64 is rotatably coupled to the frame 4. Two main sprockets 61 are coaxially fixed on the drive shaft 64.

[0032] Preferably, the bending auxiliary wheel mechanism includes a first auxiliary sprocket 65 for supporting the lower half of the chain 63 to bend and change direction, and an arc-shaped support plate 66 for supporting the upper half of the chain 63 to bend and change direction. Two auxiliary sprockets 67 are provided on both sides of the arc-shaped support plate 66 in the circumferential direction to support the upper part of the chain 63.

[0033] In Example 2, the drive motor 6 starts, driving the transmission shaft 64 to rotate, thereby realizing the rotation of the main sprocket 61. When the door is opened, the chain 63 drives the door body 1 to move along the L-shaped guide rail 2, causing the door body 1 to wind along the turbine guide rail 3; when the door is closed, the chain 63 drives the door body 1 to move along the L-shaped guide rail 2, causing the door body 1 to exit the turbine guide rail 3.

[0034] Example 3: Based on Example 1 or Example 2, such as Figures 6-8 As shown, the sealing strip 5 includes a sealing body 51 with a W-shaped cross-section. The sealing body 51 has claws 52 on both sides. The rigid door panel has first grooves 14 on both sides that engage with the claws 52.

[0035] Preferably, the end of the claw 52 is provided with a hook 521 that can be engaged into the first slot 14.

[0036] Preferably, the lower side of the sealing body 51 is provided with an auxiliary claw 53, and one side of the rigid door panel is provided with a second slot 15 that engages with the corresponding auxiliary claw 53.

[0037] Preferably, the end of the auxiliary claw 53 is provided with a locking block 531 that can be locked into the second locking slot 15.

[0038] In this application, the sealing strip 5 is made of rubber.

[0039] In Example 3, the sealing body 51 of the sealing strip 5 has a W-shaped structure, which ensures its flexibility and deformation at the bend of the L-shaped guide rail 2 and within the turbine guide rail 3. The auxiliary claw 53 strengthens the connection between the sealing strip 5 and the two rigid door panels, reduces the chance of it falling off, and improves the sealing performance.

[0040] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, they are not intended to limit the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the protection scope of the present utility model.
