[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3This utility model provides a structure for opening the end cover of a heavy-duty housing, including an end cover body 1 and a support plate 2. The long side of the support plate 2 is hinged to a support movable plate 3 via a first connector. The long side of the support movable plate 3 is hinged to a first support moving plate 4 via a second connector. A switch structure is provided between the first support moving plate 4 and the end cover body 1. The switch structure includes a second support moving plate 5 and a fixing sleeve 6. The second support moving plate 5 is vertically fixed to the long side of the first support moving plate 4. The surface of the second support moving plate 5 is provided with a through hole 7. The fixing sleeve 6 is concentrically fixed to one side of the end cover body 1. The second support moving plate 5 is rotatably connected to the surface of the fixing sleeve 6 through the through hole 7. The first connector and the second connector are both set as hinges 8. The hinges 8 are fixedly connected to the connection between the support plate 2 and the support movable plate 3, and between the support movable plate 3 and the first support moving plate 4.

[0021] The end cap body 1 is fixedly provided with a connecting part 10 for installation with the heavy-duty shell. The connecting part 10 is provided with an external thread structure. A reinforcing rib 11 is integrally formed between the end cap body 1 and the connecting part 10. Four protrusions 12 are fixedly provided at equal intervals on the surface of the end cap body 1.

[0022] Please see Figure 1 , 2 3. Since the end cap body 1 is connected to the heavy-duty housing via the connecting part 10 with an external thread structure, the end cap body 1 can be removed from the heavy-duty housing by rotating the end cap body 1 via the protrusion 12. During this process, the end cap body 1 can rotate inside the through hole 7 via the fixing sleeve 6, that is, rotate on the surface of the second bracket moving plate 5. As the connecting part 10 is continuously rotated out of the heavy-duty housing, the fixing sleeve 6 will gradually move linearly along the axis of the through hole 7 inside the through hole 7. Since the fixing sleeve 6 has a certain height, the fixing sleeve... The cylinder 6 will move horizontally on the surface of the second support moving plate 5 until the connecting part 10 is completely separated from the inside of the heavy shell. Then, through the hinge 8 between the support fixed plate 2 and the support moving plate 3, and between the support moving plate 3 and the first support moving plate 4, the support moving plate 3 can be rotated 90° while the support fixed plate 2 remains stationary. The first support moving plate 4 and the second support moving plate 5 drive the end cover body 1 to rotate 180°, so that the end cover body 1 can be removed from the heavy shell and fixed to the wall to prevent the end cover body 1 from falling off.

[0023] It should be noted that since the end cap body 1 has a certain weight, four hinges 8 are provided in this embodiment to support the weight of the end cap body 1 at the same time. At the same time, the volume of the hinges 8 needs to be set large enough within a suitable range to ensure that they can support the weight of the end cap body 1.

[0024] A retaining ring 9 is fixedly connected to the outer edge of the fixed sleeve 6. The outer diameter of the fixed sleeve 6 is the same as the inner diameter of the through hole 7, and the outer diameter of the retaining ring 9 is larger than the outer diameter of the fixed sleeve 6.

[0025] Please see Figure 1 The retaining ring 9 is designed to prevent the fixing sleeve 6 from coming off the inside of the through hole 7, and further ensures that the end cap body 1 can be fixed on the second bracket moving plate 5 after it is opened.

[0026] A limiting structure is provided between the fixed plate 2 of the bracket and the moving plate 4 of the first bracket. The limiting structure includes a groove 13 and a U-shaped connecting rod 14. The two grooves 13 are respectively opened on the top of the fixed plate 2 of the bracket and the moving plate 4 of the first bracket. The two ends of the U-shaped connecting rod 14 are respectively inserted into the two grooves 13.

[0027] Please see Figure 1 and 2 When the end cap body 1 is connected to the heavy-duty shell, the support fixed plate 2, the support movable plate 3, and the first support movable plate 4 are on the same straight line. At this time, the support fixed plate 2, the support movable plate 3, and the first support movable plate 4 can be connected to the inside of the two grooves 13 by the U-shaped connecting rod 14 to form a whole. Before the end cap body 1 is flipped, the U-shaped connecting rod 14 needs to be disengaged from the inside of the groove 13. When the end cap body 1 is flipped 180°, the first support movable plate 4 and the support fixed plate 2 can still move relative to each other. At this time, the end cap body 1 is prone to movement due to external force collision, which may cause safety hazards to the workers or mechanical equipment that are loading or unloading materials. Therefore, when the end cap body 1 is flipped 180°, the two ends of the U-shaped connecting rod 14 need to be re-inserted into the inside of the two grooves 13 to achieve locking between the first support movable plate 4 and the support fixed plate 2.

[0028] It should be noted that the straight-line distance from the center of the two grooves 13 to the center point of the support movable plate 3 is the same. After the grooves 13 on the first support movable plate 4 are rotated 180°, the distance between the centers of the two grooves 13 needs to be the same as the distance between the bottom centers of the U-shaped connecting rod 14 in order to ensure that the U-shaped connecting rod 14 can be connected inside the two grooves 13 before and after the rotation. The end face projections of the grooves 13 and the U-shaped connecting rod 14 are both circular. This is to ensure that the U-shaped connecting rod 14 can enter the grooves 13 at any angle.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
