Description
Technical Field
[0001] The utility model relates to the technical field of lifting doors, in particular to a lifting door that is convenient for entry and exit. Background Art
[0002] The lifting door is also called the industrial lifting door. It is mainly used in large warehouses, painting workshops, small hangars and other occasions. The lifting door can follow the tracks installed on the ceiling and walls, so that the space can be effectively and reasonably utilized when the door is in operation. The lifting door adopts the bearing operation mode, which overcomes the problem of high noise when the rolling door is in operation. At the same time, small doors and windows can be opened on the lifting door to facilitate people to enter and exit.
[0003] Some existing lifting doors will be equipped with an additional small door for people to exit, and the entire lifting door will only be opened and closed when vehicles enter or exit, which is convenient to operate. In order to avoid the small door being in an open state and colliding with other objects during the lifting process of the entire lifting door, most lifting doors with small doors usually use a sensor to detect whether the small door is in an open state. If the small door is in an open state, the lifting door cannot be opened as a whole. Although this method is safer, the actual operation is cumbersome, and the staff needs to walk to the small door to close the small door, and then walk back to the switch to open the lifting door. Utility Model Content
[0004] Based on this, the purpose of the utility model is to provide a lifting door that is easy to enter and exit, so as to solve the technical problems mentioned in the above background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a lifting door that is easy to enter and exit, comprising a guide rail, a door frame and a small door, a damper is installed on one side of the interior of the door frame, and a relay plate is connected to the top of the damper, a tension spring is connected between the relay plate and the door frame, a pulley is connected to the top of the door frame, a pull plate is connected to the top of the outer surface of the small door, and a pull rope is connected between the pull plate and the relay plate.
[0006] By adopting the above technical solution, when the small door is opened, the pull rope is pulled by the pull plate, and then the pull rope pulls the damper and the tension spring through the relay plate, so that the tension spring is stretched. When no one applies force to the small door, the tension spring loses the external force and drives the relay plate to slide down and reset. After the relay plate moves down, the pull plate is pulled by the pull rope, so that the small door is automatically closed. At the same time, the damper is used for buffering to avoid the impact force caused by closing the door too quickly.
[0007] Furthermore, the relay plate is slidably connected to the door frame.
[0008] By adopting the above technical solution, when the small door is opened, the pull rope is pulled by the pull plate, and then the pull rope pulls the damper and the tension spring through the relay plate. When no one applies force to the small door, the tension spring loses the external force and drives the relay plate to slide down and reset.
[0009] Furthermore, two pulleys are provided, and the two pulleys are vertically distributed.
[0010] By adopting the above technical solution, when the pull rope is pulled, the resistance to the pull rope is reduced by the provision of two pulleys, thereby avoiding wear caused by friction between the pull rope and the door frame.
[0011] Furthermore, the pull rope is in contact with two pulleys.
[0012] By adopting the above technical solution, the pull rope is pulled by the pull plate and guided by the pulley, thereby changing the direction of the force transmitted by the pull rope and reducing the sliding resistance of the pull rope.
[0013] Furthermore, a door panel is connected to the inside of the guide rail, and a door frame is connected to one side of the inside of the door panel, the small door is connected to the middle of the inside of the door frame, a handle is connected to one side of the outer surface of the small door, reinforcing beams are connected to both sides of the door panel and the outer surface of the small door, and small windows are penetrated by the door panel and the outer surface of the small door.
[0014] By adopting the above technical solution, the rotating switch of the small door facilitates the entry and exit of personnel, so there is no need to raise the door panel when the staff enters and exits, thereby reducing energy consumption. When a vehicle needs to enter and exit, the door panel rises to facilitate the passage of the vehicle.
[0015] Furthermore, the door panel is slidably connected to the guide rail, and the small door is rotatably connected to the door frame via a hinge.
[0016] By adopting the above technical solution, when the vehicle needs to drive in or out, the door panel rises upward, and during the process of lifting and lowering the door panel, the door panel is guided by the guide rail.
[0017] Furthermore, a plurality of reinforcing beams are provided, and the plurality of reinforcing beams are distributed in parallel.
[0018] By adopting the above technical solution, the structural strength of the door panel and the small door is increased by setting a plurality of reinforcing beams, thereby reducing the impact of collision and structural weight on the strength of the lifting door.
[0019] Furthermore, there are multiple small windows, and the multiple small windows are equidistantly distributed.
[0020] By adopting the above technical solution and setting up multiple small windows, indoor lighting is increased, and it is convenient for staff to check the outside situation through the small windows indoors.
[0021] Furthermore, a hydraulic cylinder is installed on one side of the guide rail, and an output end of the hydraulic cylinder is connected to a top plate via a piston rod.
[0022] By adopting the above technical solution, the switch state of the small door is monitored through the original sensor circuit. If the small door is always in the open state, it means that the structure that drives the small door to close automatically through the tension spring cannot work normally. Then the hydraulic cylinder is opened by the electric signal. After the hydraulic cylinder is started, it drives the top plate to move toward the small door. Since one side of the top plate is inclined, even if the small door is rotated 180 degrees to fit the door panel, the displacement of the top plate will push the small door to rotate it. Then the reinforcing beam on the small door is pushed by the top plate to apply force to the small door, thereby closing the small door.
[0023] Furthermore, one side of the top plate is sloped.
[0024] By adopting the above technical solution, since one side of the top plate is inclined, even if the small door is rotated 180 degrees to fit the door panel, the displacement of the top plate will push the small door to make it rotate, and then the top plate will push the reinforcing beam on the small door to apply force to the small door, thereby closing the small door.
[0025] In summary, the utility model mainly has the following beneficial effects:
[0026] The utility model is provided with a pull plate, a pulley, a pull rope, a damper, a relay plate and a tension spring. When the small door is opened, the pull rope is pulled by the pull plate, and then the pull rope pulls the damper and the tension spring through the relay plate, so that the tension spring is stretched. When no one applies force to the small door, the tension spring loses the influence of external force and drives the relay plate to slide down and reset. After the relay plate moves down, the pull plate is pulled by the pull rope, so that the small door is automatically closed. At the same time, the damper is used for buffering to avoid the impact force generated by closing the door too quickly. The door can be closed automatically, and the structure is simple and the operation is convenient. BRIEF DESCRIPTION OF THE DRAWINGS

The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0034] The following describes an embodiment of the utility model based on its overall structure.
[0035] Embodiment 1:
[0036] A lifting door that facilitates entry and exit, such as Figure 1-Figure 5 As shown, it includes a guide rail 1, a door frame 7 and a small door 8. A damper 13 is installed on one side of the door frame 7 to prevent the door from closing too quickly and generating impact force. A relay plate 14 is connected to the top of the damper 13. The relay plate 14 is slidably connected to the door frame 7. A tension spring 15 is connected between the relay plate 14 and the door frame 7. The tension spring 15 loses the external force to drive the relay plate 14 to slide down and reset. After the relay plate 14 moves down, the pull plate 10 is pulled by the pull rope 12, so that the small door 8 is automatically closed; two pulleys 11 are connected to the upper part of the door frame 7. The two pulleys 11 are distributed vertically, and a pull plate 10 is connected above the outer surface of the small door 8. A pull rope 12 is connected between the pull plate 10 and the relay plate 14. The pull rope 12 is a steel wire rope. The pull rope 12 contacts the two pulleys 11. When the small door 8 is opened, the pull rope 12 is pulled by the pull plate 10 and guided by the pulley 11 to change the direction of the force transmitted by the pull rope 12 and reduce the sliding resistance of the pull rope 12. Then the pull rope 12 pulls the damper 13 and the tension spring 15 through the relay plate 14, so that the tension spring 15 is stretched under force.
[0037] See also Figure 1-Figure 5 In the above embodiment, a door panel 2 is connected to the inside of the guide rail 1, and the door panel 2 is slidably connected to the guide rail 1 to guide the door panel 2; a door frame 7 is connected to one side of the inside of the door panel 2, and a small door 8 is connected to the middle of the inside of the door frame 7. The small door 8 is rotatably connected to the door frame 7 through a hinge, and a handle 9 is connected to one side of the outer surface of the small door 8 to facilitate pedestrian entry and exit; reinforcing beams 3 are connected to both sides of the outer surfaces of the door panel 2 and the small door 8, and a plurality of reinforcing beams 3 are provided, and the plurality of reinforcing beams 3 are distributed in parallel to increase the structural strength of the lifting door; small windows 6 are penetrated on the outer surfaces of the door panel 2 and the small door 8, and a plurality of small windows 6 are provided, and the plurality of small windows 6 are equidistantly distributed to facilitate indoor staff to view the outside world.
[0038] Embodiment 2:
[0039] On the basis of the above-mentioned embodiment 1, although the door can be closed automatically by setting the pull plate 10, pulley 11, pull rope 12, damper 13, relay plate 14 and tension spring 15, the structure is simple and the operation is convenient; however, if the above-mentioned structure is aged and damaged and cannot automatically close the small door, the staff is still required to manually close the door; now by setting the hydraulic cylinder 4 and the top plate 5, the small door can be automatically closed.
[0040] See also Figure 1 In the above embodiment, a hydraulic cylinder 4 is installed on one side of the guide rail 1, and the output end of the hydraulic cylinder 4 is connected to a top plate 5 through a piston rod. One side of the top plate 5 is in a slope shape. The switch state of the small door 8 is monitored by the original sensor circuit. If the small door 8 is always in an open state, it means that the structure that drives the small door 8 to automatically close by the tension spring 15 cannot work normally. Then, the hydraulic cylinder 4 is opened by the influence of the electric signal. After the hydraulic cylinder 4 is started, it drives the top plate 5 to move toward the direction of the small door 8. Since one side of the top plate 5 is in an inclined surface, even if the small door 8 is rotated 180 degrees to fit the door panel 2, the displacement of the top plate 5 will push the small door 8 to rotate the small door 8, and then the reinforcing beam 3 on the small door 8 is pushed by the top plate 5 to apply force to the small door 8, thereby closing the small door 8.
[0041] The implementation principle of the utility model is as follows: first, the lifting door is an electric lifting door, and the specific operation mode is the existing technology, so the technical solution is not repeated. During the lifting process of the door panel 2, the guide rail 1 guides the door panel 2, and the reinforcing beam 3 increases the strength of the door panel 2;
[0042] When the staff member opens the small door 8, he pulls the pull rope 12 through the pull plate 10 and guides it through the pulley 11 to change the direction of the force transmitted by the pull rope 12 and reduce the resistance of the pull rope 12 to slide. Then, the pull rope 12 pulls the damper 13 and the tension spring 15 through the relay plate 14, so that the tension spring 15 is stretched. When no one applies force to the small door 8, the tension spring 15 loses the external force and drives the relay plate 14 to slide down and reset. After the relay plate 14 moves down, it pulls the pull plate 10 through the pull rope 12, so that the small door 8 is automatically closed. At the same time, the damper 13 is used for buffering to avoid the impact force caused by closing the door too quickly.
[0043] When the structure of the automatic door closing is damaged, the staff can start the hydraulic cylinder 4. After the hydraulic cylinder 4 is started, it drives the top plate 5 to move toward the small door 8. Since one side of the top plate 5 is inclined, even if the small door 8 is rotated 180 degrees to fit the door panel 2, the displacement of the top plate 5 will push the small door 8 to make the small door 8 rotate. Then, the reinforcing beam 3 on the small door 8 is pushed by the top plate 5, thereby applying force to the small door 8, thereby closing the small door 8.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
