[0031] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0032] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0034] In order to solve the problem in the prior art that workers need to remove the observation window cover when observing the OT line on the flywheel, which increases the labor intensity of the workers, the present application provides a window cover assembly and a flywheel housing having the same.

[0035] like Figures 1 to 6As shown, the window cover assembly is used to be installed on the observation window of the flywheel housing body, and the window cover assembly includes a frame 20, a cover plate 30 and a buckle assembly 40. Among them, the frame 20 has a first through hole 21 corresponding to the observation window, and the cover plate 30 is rotatably arranged on the frame 20. The cover plate 30 has a shielding state of shielding the first through hole 21 and an observable state of avoiding at least a part of the first through hole 21. When the cover plate 30 is in the shielding state, the cover plate 30 is connected to the frame 20 through the buckle assembly 40.

[0036] By applying the technical solution of this embodiment, in the initial state, the cover plate 30 blocks the first through hole 21 and is in a blocking state, thereby preventing impurities and foreign objects such as dust from entering the observation window through the first through hole 21, so as to fully protect the observation window; when the staff needs to observe the OT lines on the flywheel, they only need to operate the cover plate 30 to rotate from the blocking state to the observable state of avoiding at least part of the first through hole 21. At this time, the first through hole 21 is arranged opposite to the observation window, and the staff can observe the OT lines in the observation window through the first through hole 21. After the staff has completed the observation of the OT lines, they can operate the cover plate 30 to slide to the blocking state.

[0037] Compared with the prior art that requires the observation window cover to be removed as a whole, the window cover assembly in this embodiment is installed as a whole on the flywheel housing body. The staff only needs to operate the cover 30 to rotate to observe or cover the observation window without removing the cover 30, thereby making it easier and more convenient for the staff to operate the cover 30. This solves the problem in the prior art that the staff needs to remove the observation window cover when observing the OT line on the flywheel, which increases the labor intensity of the staff and reduces the labor intensity of the staff.

[0038] In this embodiment, the window cover assembly is directly welded to the flywheel housing body in the form of an assembly rather than an independent component, thereby reducing the number of parts and the corresponding management costs and installation procedures.

[0039] like Figures 1 to 6 As shown, the snap-fit ​​assembly 40 includes a first snap-fit ​​portion 41 and a second snap-fit ​​portion 42. The first snap-fit ​​portion 41 is arranged on the frame 20, and the second snap-fit ​​portion 42 is arranged on the cover plate 30. One of the first snap-fit ​​portion 41 and the second snap-fit ​​portion 42 is a recess, and the other of the first snap-fit ​​portion 41 and the second snap-fit ​​portion 42 is an elastic snap-fit ​​portion, which can be extended into the recess and limitedly matched with the recess to realize the connection between the cover plate 30 and the frame 20. In this way, the above arrangement makes the structure of the snap-fit ​​assembly 40 simpler, easier to process and realize, and reduces the processing cost and difficulty of the snap-fit ​​assembly 40; on the other hand, it makes the structural selection of the snap-fit ​​assembly 40 more flexible to meet different usage requirements and working conditions, and also improves the processing flexibility of the snap-fit ​​assembly 40.

[0040] Specifically, in the initial state, the elastic buckle part extends into the recess and cooperates with the recess to fix the cover plate 30 on the frame 20. At this time, the cover plate 30 can cover the observation window to prevent dust and other impurities from entering the observation window. When the staff needs to observe the OT engraved line on the flywheel, the cover plate 30 is rotated to make the elastic buckle part elastically deform and escape from the recess until the cover plate 30 is rotated to avoid at least part of the first through hole 21. At this time, the observation window is exposed to the outside for the staff to observe, thereby reducing the difficulty of operation for the staff.

[0041] In this embodiment, the frame 20 is quadrilateral, and when the cover plate 30 is in the shielding state, the pivot axis of the cover plate 30 and the buckle assembly 40 are arranged at intervals along the diagonal line of the frame 20 and are respectively located on both sides of the first through hole 21. In this way, when the cover plate 30 is in the shielding state, the above arrangement improves the connection stability between the cover plate 30 and the frame 20, and prevents the two from being separated from each other and affecting the shielding reliability of the window cover assembly on the observation window. At the same time, the above arrangement makes the structure of the frame 20 simpler, easier to process and realize, and reduces the processing cost and difficulty of the frame 20.

[0042] Optionally, the recess is a second through hole, and the elastic buckle portion includes a connecting section 411 and an elastic arm section 412. Among them, one end of the connecting section 411 is connected to the frame 20 or the cover plate 30. The other section of the connecting section 411 is connected to the elastic arm section 412, and at least part of the elastic arm section 412 can extend into the second through hole and cooperate with the second through hole to achieve the limited cooperation between the elastic buckle portion and the recess. In this way, the above arrangement not only ensures that the elastic buckle portion can undergo elastic deformation, but also makes the structure of the elastic buckle portion simpler, easy to process and realize, thereby reducing the processing cost and difficulty of the buckle assembly 40. At the same time, the above arrangement makes the structure of the recess simpler, easy to process and realize.

[0043] In this embodiment, the frame 20 has a second through hole, one end of the connecting section 411 is connected to the frame 20, and the other end of the connecting section 411 is connected to the elastic arm section 412. In this way, in the initial state, the elastic arm section 412 extends into the second through hole and cooperates with the second through hole to fix the cover plate 30 on the frame 20 to cover the observation window; when the staff rotates the cover plate 30, the cover plate 30 pushes the elastic arm section 412 to undergo elastic deformation and escape from the second through hole, thereby ensuring that the cover plate 30 can be rotated to avoid the observation window.

[0044] like Figure 5As shown, the connecting section 411 includes a first plate section 4111 and a second plate section 4112 connected to each other, the first plate section 4111 and the second plate section 4112 are arranged at a first angle, one end of the first plate section 4111 away from the second plate section 4112 is connected to the frame 20 or the cover plate 30, and one end of the second plate section 4112 away from the first plate section 4111 is connected to the elastic arm section 412. Optionally, the first angle is 90°. In this way, the above arrangement makes the structure of the connecting section 411 simpler, easier to process and realize, and reduces the processing cost and difficulty of the connecting section 411.

[0045] like Figure 5 As shown, the elastic arm segment 412 includes a third plate segment 4121 and a fourth plate segment 4122, the third plate segment 4121 is connected to the second plate segment 4112, and the fourth plate segment 4122 is connected to the third plate segment 4121 and is arranged at a second angle to the third plate segment 4121. The third plate segment 4121 is arranged at a third angle to the second plate segment 4112, the third plate segment 4121 and the first plate segment 4111 are located on the same side of the second plate segment 4112, and the second plate segment 4112 and the fourth plate segment 4122 are located on both sides of the third plate segment 4121 respectively; the plate surface of the third plate segment 4121 facing the first plate segment 4111 is used for limiting and stopping with the hole wall of the second through hole. In this way, the above arrangement makes the structure of the elastic arm segment 412 simpler, easier to process and realize, and reduces the processing cost and difficulty of the elastic buckle portion.

[0046] In this embodiment, the elastic buckling portion is an integrally formed structure.

[0047] Optionally, at least part of the hole wall of the second through hole is an inclined surface, and when the elastic arm segment 412 slides into or out of the second through hole, the inclined surface is used to guide the elastic arm segment 412. In this way, when the staff operates the cover plate 30 to rotate relative to the frame 20, the inclined surface can guide the elastic arm segment 412, thereby ensuring that the elastic arm segment 412 can escape from the second through hole or facilitate the elastic arm segment 412 to slide into the second through hole, reducing the difficulty of operation for the staff.

[0048] like Figure 1 , Figure 2 , Figure 4 as well as Figure 6 As shown, the window cover assembly further includes a stopper structure 50, which is disposed on the cover plate 30, and the second buckle portion 42 is located between the stopper structure 50 and the pivot axis of the cover plate 30, and the stopper structure 50 is used to limit and stop the first buckle portion 41. The height of the stopper structure 50 is higher than the height of the first buckle portion 41. In this way, when the staff operates the cover plate 30 to rotate, the above-mentioned setting of the stopper structure 50 can prevent the cover plate 30 from avoiding the first through hole 21 due to excessive rotation, thereby ensuring that the cover plate 30 rotates within a preset range.

[0049] Specifically, the stop structure 50 includes a fifth plate segment, a sixth plate segment, a seventh plate segment and an eighth plate segment that are bent in sequence, the fifth plate segment is connected to the frame 20, the seventh plate segment is arranged opposite to the fifth plate segment, the eighth plate segment and the sixth plate segment are respectively located on both sides of the seventh plate segment, and the eighth plate segment is fitted to the frame 20. The height of the eighth plate segment is higher than the height of the elastic buckle portion.

[0050] like Figure 6 As shown, the frame 20 has a mounting hole, the cover plate 30 has a third through hole, and the window cover assembly further includes a connecting column 60. The connecting column 60 is inserted into the mounting hole and the third through hole, and the cover plate 30 is pivotally connected to the frame 20 via the connecting column 60. In this way, the above arrangement ensures that the cover plate 30 can rotate relative to the frame 20, thereby improving the rotation stability and rotation reliability of the cover plate 30; on the other hand, it makes the disassembly and assembly of the cover plate 30 and the frame 20 easier and simpler, thereby reducing the overall processing cost and processing difficulty of the window cover assembly.

[0051] The present application also provides a flywheel housing, comprising a flywheel housing body and a window cover assembly arranged on the flywheel housing body, wherein the window cover assembly is the above-mentioned window cover assembly.

[0052] Specifically, the frame 20 of the window cover assembly is welded to the flywheel housing body.

[0053] From the above description, it can be seen that the above embodiments of the utility model achieve the following technical effects:

[0054] The window cover assembly includes a frame, a cover plate and a snap-fit ​​assembly, and the frame has a first through hole corresponding to the observation window. The cover plate is rotatably arranged on the frame, and the cover plate has a blocking state of blocking the first through hole and an observable state of avoiding at least part of the first through hole. When the cover plate is in the blocking state, the cover plate is connected to the frame through the snap-fit ​​assembly. In this way, in the initial state, the cover plate blocks the first through hole and is in a blocking state, thereby preventing impurities and foreign objects such as dust from entering the observation window through the first through hole, so as to fully protect the observation window; when the staff needs to observe the OT lines on the flywheel, it is only necessary to operate the cover plate to rotate from the blocking state to the observable state of avoiding at least part of the first through hole. At this time, the first through hole is arranged opposite to the observation window, and the staff can observe the OT lines located in the observation window through the first through hole. After the staff completes the observation of the OT lines, operate the cover plate to slide to the blocking state.

[0055] Compared with the prior art that requires the observation window cover to be removed as a whole, the window cover assembly in the present application is installed as a whole on the flywheel housing body. The staff only needs to operate the cover to rotate to observe or cover the observation window without removing the cover, which makes it easier and simpler for the staff to operate the cover. This solves the problem in the prior art that the staff needs to remove the observation window cover when observing the OT line on the flywheel, which increases the labor intensity of the staff and reduces the labor intensity of the staff.
