[0034] As Figures 2 to 10 shown, the maintenance window structure of the communication device includes a housing 10, a hinge mechanism 20 and a maintenance window cover 30, asFigure 2 As shown in the figure, inside the housing 10, there is a space for accommodating electronic devices and a window for the maintenance of internal electronic devices; the hinge mechanism 20 includes a hinge base 21 fixedly connected to the housing 10 and a rotating shaft 22 rotatably connected inside the hinge base 21; specifically, please refer to Figure 3 , in the embodiment of the present invention, the hinge base 21 is fixed to the housing 10 by screws. One end of the rotating shaft 22 is rotatably connected inside the hinge base 21, and the other end penetrates into the maintenance window cover 30. And in the embodiment of the present invention, the rotating shaft 22 does not rotate relative to the maintenance window cover 30; the maintenance window cover 30 is adaptively arranged with the window of the housing 10, and one end of the maintenance window cover 30 is fixedly connected to the rotating shaft 22; wherein, the hinge base 21 is also provided with a damping adjustment mechanism 40 for adjusting the rotation damping of the rotating shaft 22. It should be noted here that there are various ways to adjust the rotation damping of the rotating shaft 22. For example, a friction plate can be installed on the rotating shaft 22, and the damping can be adjusted by adjusting the friction force between the friction plate and the rotating shaft 22; or a small hydraulic damper can be installed at the hinge part of the rotating shaft 22 to generate resistance through the flow of liquid; or a torsion spring can be installed on the rotating shaft 22, and the damping can be provided by adjusting the torsional force of the spring and other ways to achieve.

[0035] During the specific installation, first install the rotating shaft 22 on the maintenance window cover 30, then penetrate the other end of the rotating shaft 22 into the hinge base 21, and finally fix the hinge base 21 on the housing 10. By adjusting the damping of the rotating shaft 22, the maintenance window can be hovered at any angle when it is opened.

[0036] In the above embodiment, through the rotational connection between the rotating shaft 22 and the hinge base 21 in the hinge mechanism 20, and the fixed connection between the maintenance window cover 30 and the rotating shaft 22, the opening and closing of the maintenance window cover 30 relative to the housing 10 are realized. And through the setting of the damping adjustment mechanism 40 on the hinge base 21, the rotation damping of the rotating shaft 22 can be adjusted, and then the maintenance window cover 30 can be opened to any angle. Since the rotation damping of the rotating shaft 22 is adjustable, compared with the prior art, the reliability of the use of the maintenance window cover 30 is improved.

[0037] On the basis of the above embodiment, in some embodiments of the present invention, the specific structural form of the damping adjustment mechanism 40 is as shown in Figure 5 and Figure 6 , the damping adjustment mechanism 40 includes a slotted hole 41 provided on the hinge base 21 and an adjusting member 42 for adjusting the slot spacing of the slotted hole 41. The rotating shaft 22 is rotatably connected in the hole of the slotted hole 41. Here, the slotted hole 41 refers to a hole opened on the hinge base 21 for the rotating shaft 22 to insert and rotate relatively, as shown in Figure 5 and Figure 6As shown in the figure, one side of the hole is slotted. By adjusting the gap of the slot, the resistance during the rotation of the rotating shaft 22 can be adjusted, and thus the rotational damping of the rotating shaft 22 is adjusted. In the embodiment of the present invention, the adjusting member 42 is a screw. The stud of the screw penetrates through the slot body of the slotted hole 41, and the screw is screwed onto the hinge seat 21 to adjust the size of the slot body. During specific maintenance, after the maintenance personnel open the maintenance window cover 30, since the slotted hole 41 presses against the rotating shaft 22, a damping force that prevents the maintenance window cover 30 from closing again is generated, that is, a damping force, so as to realize the retention of the maintenance window cover 30 at any angle.

[0038] In some embodiments of the present invention, the specific structure of the rotating shaft 22 is as Figure 7 shown in the figure. The rotating shaft 22 includes a cylinder 22a and a square body 22b. The cylinder 22a is connected to the hinge seat 21, and the square body 22b is connected to the maintenance window cover 30. It should be noted here that the square body 22b in the embodiment of the present invention refers to a prism structure with a rectangular cross-section. By setting one end of the rotating shaft 22 inserted into the plate of the maintenance window cover 30 to be a non-cylindrical structure, the synchronous rotation of the maintenance window cover 30 and the rotating shaft 22 can be realized; specifically as Figure 8 and Figure 9 shown in the figure. The maintenance window cover 30 has a convex block 31 arranged away from the end at the hinge end. Both sides of the convex block 31 have grooves 31a for inserting the square body 22b. It should be noted here that in the embodiment of the present invention, the cross-section of the groove 31a fits the square body 22b at least on two opposite sides, specifically as Figure 9 shown in the figure, Figure 9 the upper and lower sides of the groove 31a in the figure are stop edges. By the fitting of the stop edges with the two side walls of the square body 22b, the relative rotation of the rotating shaft 22 with respect to the maintenance window cover 30 can be avoided.

[0039] Please continue to refer to Figure 9 , in some embodiments of the present invention, in order to reduce the precision of the hinge mechanism 20 and increase the tolerance redundancy of the fit between the maintenance window cover 30 and the housing 10, the width of the groove 31a in the embodiment of the present invention is adapted to the thickness of the square body 22b, and the length of the groove 31a is greater than the width of the square body 22b. Through the setting of this structural form, the rotating shaft 22 can move slightly along the stop edge. Through the setting of this structural form, the above requirements are met, and at the same time, the cost of part processing is reduced, the defective rate during the processing is reduced, and the sealing risk caused by processing errors can also be reduced.

[0040] In some embodiments of the present invention, in order to prevent rainwater and dust from entering the housing 10, as Figure 10As shown, there is also a sealing strip 50 on the surfaces of the maintenance window cover 30 and the housing 10 facing each other. The sealing strip 50 is provided on the maintenance window cover 30 and / or the housing 10. It should be noted here that in some embodiments of the present invention, the sealing strip 50 can be provided on the lower surface of the maintenance window cover 30, or on the upper surface of the window of the housing 10, as Figure 10 shown, it can also be provided on the periphery of the emergence hole of the housing 10; the fixing of the sealing strip 50 can be achieved by glue bonding or bonding with other substances, or by snap fasteners or other structural forms to fix the sealing strip 50.

[0041] In the embodiments of the present invention, as Figure 8 shown, there is also a non-removable connecting member 60 on the end of the maintenance window cover 30 far from its hinge. The non-removable connecting member 60 is screwed to the housing 10. Here, the non-removable connecting member 60 is a non-removable screw, that is, in the embodiments of the present invention, there is a part without threads on the screw, and the screw cannot be detached from the maintenance window cover 30 by turning the screw. By this way, the convenience of opening and locking the maintenance window cover 30 can be improved. The non-removable screw is connected to the housing 10 through a threaded hole.

[0042] In some embodiments of the present invention, in order to improve the installation compactness of the hinge seat 21, as Figure 10 shown, the housing 10 also has an installation groove for installing the hinge seat 21. The width of the convex block 31 is smaller than the body width of the maintenance window cover 30 and is located between the two hinge seats 21. Through the setting of this structural form, the overall installation size of the hinge seat 21 is more compact, and in combination with the structural form of the convex block 31 and the groove 31a, a temporary locking state can also be achieved, that is, when the movable maintenance window cover 30 is moved so that the rotating shaft 22 is at the innermost part of the groove 31a, at this time, the front end of the convex block 31 abuts against the housing 10 when opened, so that the maintenance window cover 30 cannot be opened, and when the maintenance window cover 30 is pulled so that the rotating shaft 22 is at the outermost side, the abutment between the convex block 31 and the housing 10 is eliminated, and thus the maintenance window cover 30 can be opened at any angle.

[0043] Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention.
