Description

Technical Field

[0001] The utility model relates to the technical field of industrial exterior protection, in particular to a lifting door used in industrial exterior protection. Background Art

[0002] At present, for industrial exterior protection lifting doors, workers need to pull the door upwards with force when opening, and need to hold the door with their hands and slowly lower it when closing. For light doors, workers will not feel much effort when opening and closing the door, but when opening and closing heavy doors, workers will feel very strenuous. Therefore, in order to reduce the work intensity of workers, most of the current lifting doors are designed to use an opening and closing mechanism composed of components such as motors or cylinders to drive the door up and down.

[0003] Changing to a motor or cylinder to drive the opening and closing of the lift door can naturally save manpower and reduce the labor intensity of the staff. However, once a power outage or other fault occurs, the lift door cannot be opened and closed automatically. A set of opening and closing mechanisms will make it more difficult to open and close the lift door manually, increasing the difficulty of opening and closing the lift door manually. Utility Model Content

[0004] In view of this, the utility model provides a lifting door used in industrial exterior protection, which uses a plurality of tension springs to offset a portion of the weight of the lifting door body, thereby reducing the labor intensity of manually opening and closing the lifting door.

[0005] To this end, the present application provides the following technical solutions: a lifting door used in industrial exterior protection, comprising a shell for industrial exterior protection, a rear lining plate being installed on one side of the door end of the shell, the rear lining plate blocking the upper half of the door end, and the lower half of the door end being an open doorway; two sliding rails are fixed side by side on the rear lining plate in the vertical direction, a slider is slidably connected to the sliding rail, a door panel is fixedly connected to the slider, a hook plate is fixedly connected to the plate body at the lower part of the door panel, a number of tension springs are hooked in the hook plate, and the other end of the tension spring is connected to the shell at the upper end of the door panel; when the door panel falls, the doorway can be blocked, and when the door panel rises, the doorway can be exposed.

[0006] Furthermore, a handle is provided on the door panel.

[0007] Furthermore, a lock tongue is mounted on the door panel, and a lock buckle matched with the lock tongue is mounted on the shell below the door panel.

[0008] Furthermore, a front guard plate is fixedly mounted on the shell outside the rear lining plate, the upper portion of the front guard plate is a plate-like structure, and a large notch is provided on the lower portion of the front guard plate.

[0009] Furthermore, a plurality of strong magnetic door bumpers are mounted on the shell at the upper end of the lifting door.

[0010] The beneficial effect of the utility model is that the utility model hooks a plurality of tension springs on the door panel of the lifting door. When the door panel moves upward under the pulling of the operator, the tension force of the tension spring offsets most of the weight of the door panel, which facilitates the operator to lift the door panel; when the door panel moves downward under the pulling of the operator, the tension force of the tension spring also offsets most of the weight of the door panel, which plays a role in preventing the door panel from falling quickly. Therefore, the utility model only uses a plurality of tension springs to greatly reduce the labor intensity of the operator, and avoids the embarrassing situation that the door cannot be opened or closed smoothly due to unexpected situations such as power outages when using electric, pneumatic and other opening and closing mechanisms to open and close the door.

[0021] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the utility model. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0022] Example 1.

[0023] The utility model provides a lifting door used in industrial exterior protection, such as Figure 1-6 As shown, it includes a housing 1 for industrial exterior protection, a rear lining plate 11 is installed on one side of the housing door end, the rear lining plate blocks the upper half of the door end, and the lower half of the door end is an open doorway. Four fixing seats 8 are fixed on the rear lining plate. A cylindrical slide rail 7 is installed in each of the two fixing seats in the vertical direction, and two sliders 6 are slidably connected in each slide rail. The door panels 3 of the lifting doors 3-6 are connected to the sliders and can move up and down along the slide rails with the sliders. The specific structure of the lifting door is as follows:

[0024] The invention comprises a door panel, and a slider is fixed at four corners of the door panel. A hook plate 4 is fixedly connected to the plate body at the lower part of the door panel, and a plurality of round holes are arranged side by side on the hook plate, and a tension spring 5 is hooked in the round hole, and the other end of the tension spring is connected to the housing located at the upper end of the door panel.

[0025] like Figure 1 , 2 As shown, a handle 12 and a lock tongue 9 are mounted on the outer side of the door panel, and a lock buckle 13 that can match the lock tongue is mounted on the lower part of the housing.

[0026] When opening, first unlock the lock tongue and the lock catch. The lift door will move upward or have a tendency to move upward under the action of the tension spring. This depends on the comparison between the tension of the spring and the weight of the lift door. When the tension spring is in the maximum tension state, the combined force of the five tension springs is slightly greater than the weight of the lift door. When opening the lift door, the operator can smoothly pull the lift door upward with the help of the tension spring, and the door panel rises to reveal the door; when closing the lift door, the operator does not have to work too hard to resist the tension of the tension spring. When closing, the operator pulls down the lift door, and when the lock tongue is inserted into the lock catch, the lift door is closed, and the door panel blocks the door after it falls.

[0027] Example 2.

[0028] In order to enhance the aesthetics and protect the tension spring, slider, rail and other components, a front guard plate 2 is fixedly installed on the outer protective shell outside the rear lining plate. Figure 1 , 2 As shown in 4, the upper part of the front guard plate is a plate-like structure, and a large notch 2.1 is provided at the lower part. The front guard plate is connected to the frame of the shell through the upper end and the left and right ends, and the lifting door is placed at the notch. When the lifting door is raised, the notch naturally forms a passage for people or materials to pass; when the lifting door falls, the passage is blocked by the door plate.

[0029] Example 3.

[0030] like Figure 3 , 4 As shown, in order to prevent the lifting door from falling when it is open and to place the lifting door at the top when it is open, that is, the height of the door is maximized, four strong magnetic door bumpers 10 are installed on the housing at the upper end of the lifting door. When the lifting door is lifted to the top, it is attracted by the strong magnetic door bumpers. For non-ferrous door panels, an iron plate can be fixed at the position where the door panel contacts the strong magnetic door bumpers.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
