DETAILED DESCRIPTION

[0018] The utility model is described in detail below in conjunction with the accompanying drawings.

[0019] Specific embodiment 1 of a foldable protective cover for industrial equipment of the utility model:

[0020] like Figure 1-Figure 2 As shown, the foldable protective cover of industrial equipment is a box-type structure as a whole, including a main cover body 8, and door frames are provided on both horizontal sides of the main cover body 8, and folding doors are installed on the door frames, and the folding doors include a fixed revolving door 3, a floating revolving door 4, a hydraulic support rod 2 and a vertical rod 9. The top of the door frame is located on the top surface of the main cover body 8, and the top of the door frame is hinged to the inner end of the fixed revolving door 3, and the outer end of the fixed revolving door 3 is hinged to the inner end of the floating revolving door 4 through an inner hinge 5. The two sides of the outer end of the floating revolving door 4 are rotatably connected with pulleys 1, and the pulleys 1 are matched with the upper and lower guides of the slide grooves provided on both sides of the door frame, and can roll along the slide grooves, and the pulleys 1 constitute guide members.

[0021] The hydraulic support rod 2 is located on the inner side of the fixed revolving door 3, and a vertical rod 9 is vertically fixed on the inner side of the fixed revolving door 3. The two ends of the hydraulic support rod are respectively hinged with the main cover 8 and the vertical rod 9. The hydraulic support rod 2 provides a driving force for the folding door to open / close automatically in the second half of the opening / closing process of the folding door, and a handle 6 is arranged on the outer side of the outer end of the floating revolving door 4 for the convenience of personnel to apply force.

[0022] Combination Figure 3-Figure 5 The force analysis diagram of the folding door explains the opening / closing process of the folding door: the hydraulic support rod force F 合 It is decomposed into the vertical force F1 of the hydraulic support rod and the horizontal force F2 of the hydraulic support rod. When the folding door is closed, the force is as follows: Figure 3 As shown in the figure, the vertical force F1 of the hydraulic support rod and the gravity G of the folding door are both directed downward, so that the folding door remains stably closed; when opening, the operator pulls the handle 6 upward, the pulley of the floating revolving door 4 rolls upward along the slide slot, and the floating revolving door 4 drives the fixed revolving door to rotate upward, and the hydraulic support rod 2 rotates upward while extending, and moves until the vertical force F1 of the hydraulic support rod is directed upward. When the vertical force F1 of the hydraulic support rod is equal to the gravity G of the folding door, the folding door reaches the critical point of movement, that is, it is in the position shown in the figure. Figure 4 The critical state of movement is shown, and then the hydraulic support rod 2 drives the fixed revolving door 3 to rotate upward and drives the folding door to automatically rise, and the extension of the hydraulic support rod reaches the maximum value and is maintained, as shown in FIG. Figure 5As shown in the figure, the entire folding door is completely in the open state. Since the vertical force F1 of the hydraulic support rod is greater than the gravity G of the folding door, the folding door is supported by the hydraulic support rod to remain open. Therefore, as long as the operator provides a pulling force to make the folding door upward / downward in the first half of the opening / closing of the folding door, when the folding door reaches the critical state of movement, the folding door mechanism will be automatically completed by the hydraulic support rod to complete the remaining movements.

[0023] It can be found that the utility model optimizes the opening and closing method and structure of the folding door, utilizes the vertical space to open and close the protective door, and the action is less restricted by the space around the equipment. It is used in conjunction with the hydraulic support rod to provide the opening and closing power. The operation process is convenient, labor-saving, stable and safe. In addition, the fixed revolving door and the floating revolving door both include an aluminum profile frame and an acrylic protective plate 7 installed in the middle of the aluminum profile frame, which not only ensures a certain structural strength, but also takes into account lightweight and aesthetic appearance, saving space and cost.

[0024] In this embodiment, both sides of the main cover body are provided with folding doors. In other embodiments, the folding door may be provided only on one horizontal side, or the top of the door frame may be located at the top end of the side portion of the main cover body.

[0025] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model.
