The connecting member 4 can automatically reset from the unlocked position to the locked position, so that the connecting member 4 and the rotating shaft 31 are inserted and matched along the axial direction of the rotating shaft 31. When the cover plate assembly 1 of this embodiment is installed, the rotating shaft 31 can abut against the limiting member 5 to move the limiting member 5 from the limiting position to the yielding position to yield to the connecting member 4, and the connecting member 4 can automatically reset from the unlocked position to the locked position. Therefore, the cover plate assembly 1 of this embodiment can be quickly installed on the bracket 2 without operating any components, which is very convenient to use.

[0042] Please refer to Figures 1 to 6 As shown, in this embodiment, a first elastic member 7 is further included. When the rotating shaft 31 is separated from the limiting member 5, the first elastic member 7 abuts between the limiting member 5 and the cover plate assembly 1. The limiting member 5 can automatically reset from the yielding position to the limiting position under the action of the first elastic member 7, so that when the connecting member 4 moves to the unlocked position and the limiting member 5 is separated from the rotating shaft 31 (i.e., the rotating shaft 31 releases the abutment against the limiting member 5), the limiting member 5 can automatically reset to the limiting position to limit the connecting member 4 in the unlocked position.

[0043] Please refer to Figures 1 to 7 As shown, in this embodiment, a limiting portion 41 is provided on the connecting member 4, and an abutting portion 51 and a yielding notch 52 are provided on the limiting member 5. When the limiting member 5 is in the limiting position, the limiting member 5 abuts against the limiting portion 41 to limit the connecting member 4 in the unlocked position. When the limiting member 5 is in the yielding position, the limiting member 5 is disengaged from the limiting portion 41, and at the same time, the yielding notch 52 yields to the limiting portion 41 so that the connecting member 4 can reset from the unlocked position to the locked position.

The driving member 9 drives the connecting member 4 to move from the locking position to the unlocking position through the transmission member 10. The second elastic member 8 is abutted between the connecting member 4 and the cover plate assembly 1. The connecting member 4 can automatically reset from the unlocking position to the locking position under the action of the second elastic member 8. During the process of the connecting member 4 automatically resetting from the unlocking position to the locking position, it can drive the driving member 9 to reset through the transmission member 10.

[0046] Please refer to Figures 1 to 6 As shown in the figure, in this embodiment, the transmission member 10 is a gear rotatably arranged on the cover plate assembly 1. The limiting member 5, the driving member 9 and the connecting member 4 are all slidably arranged on the cover plate assembly 1, and the driving member 9 and the connecting member 4 are distributed on both sides of the gear. The driving member 9 is provided with a first tooth portion 91 that can mesh with one side of the gear, and the connecting member 4 is provided with a second tooth portion 42 that can mesh with the other side of the gear. Thus, the driving member 9 can drive the connecting member 4 to move in the opposite direction through the gear. When the driving member 9 is pressed, the driving member 9 drives the connecting member 4 to move from the locking position to the unlocking position through the transmission member 10. Specifically, in this embodiment, the transmission member 10 is rotatably arranged on the fixed seat 6, the limiting member 5, the driving member 9 and the connecting member 4 are all slidably arranged on the fixed seat 6. The first elastic member 7 and the second elastic member 8 are both springs. The first elastic member 7 is abutted between the limiting member 5 and the fixed seat 6. The connecting member 4 is provided with a guide post 44, and the second elastic member 8 is sleeved on the guide post 44 and abutted between the connecting member 4 and the fixed seat 6.

[0047] Please refer to Figures 1 to 6 As shown in the figure, in this embodiment, the connecting member 4 is provided with a slot 43, and one end of the rotating shaft 31 is in plug-in fit with the slot 43. Of course, in other embodiments, it can also be that the rotating shaft is provided with a slot, and the connecting member is provided with a convex portion, and the convex portion is in plug-in fit with the slot, which can also achieve the purpose of the present invention.

[0048] In this embodiment, the cover plate assembly 1 is a seat ring. The bracket 2 is provided with a damper 3, the rotating shaft 31 is the rotating shaft of the damper 3, and the connecting member 4 and the rotating shaft 3 cannot rotate relative to each other. In other embodiments, when the bracket 2 is not provided with a damper 3, the connecting member 4 and the rotating shaft 3 can also be rotatably connected together.

[0049] The working principle of this embodiment is briefly described as follows:

[0050] As shown in Figure 1 and Figure 2As shown, under normal conditions, the connecting member 4 is in the locked position, the rotating shaft 31 abuts against the limiting member 5 and the limiting member 5 is in the yielding position, the first elastic member 7 is compressed, the connecting member 4 and the rotating shaft 31 are inserted and matched along the axial direction of the rotating shaft 31 to connect the cover plate assembly 1 and the bracket 2 together, and the connecting member 4 is rotatably connected to the bracket 2 through the rotating shaft 31, so that the cover plate assembly 1 is rotatably connected to the bracket 2 through the rotating shaft 31;

[0051] When it is necessary to remove the cover plate assembly 1 from the bracket 2 for cleaning, as Figure 3 shown, press the driving member 9, the driving member 9 drives the connecting member 4 to move from the locked position to the unlocked position through the transmission member 10, the connecting member 4 is separated from the rotating shaft 31, so that the cover plate assembly 1 is separated from the bracket 2, and at this time the second elastic member 8 is compressed; as Figure 4 shown, then lift the cover plate assembly 1 upward (while still pressing the driving member 9), the limiting member 5 is separated from the rotating shaft 31, and the limiting member 5 automatically resets from the yielding position to the limiting position under the action of the first elastic member 7, and the pressing force acting on the driving member 9 is withdrawn, so as to limit the connecting member 4 in the unlocked position and prepare for the next installation of the cover plate assembly 1;

[0052] After the cleaning of the cover plate assembly 1 is completed, as Figure 3 shown, place the cover plate assembly 1 above the bracket 2 and make the rotating shaft 31 abut against the limiting member 5 so that the limiting member 5 moves from the limiting position to the yielding position, and the limiting member 5 yields to the connecting member 4, and the first elastic member 7 is compressed. At this time, as Figure 1 and Figure 2 shown, the connecting member 4 automatically resets from the unlocked position to the locked position under the action of the second elastic member 8, the connecting member 4 and the rotating shaft 31 are inserted and matched along the axial direction of the rotating shaft 31 to connect the cover plate assembly 1 and the bracket 2 together, and the connecting member 4 is rotatably connected to the bracket 2 through the rotating shaft 31, so as to quickly reinstall the cover plate assembly 1 on the bracket 2. During the process of the connecting member 4 automatically resetting from the unlocked position to the locked position, the driving member 9 is also driven to reset through the transmission member 10.

[0053] In other embodiments, the rotating shaft can also be arranged on the cover plate assembly, the connecting member and the limiting member are movably arranged on the bracket. Correspondingly, the connecting member can slide between the locked position and the unlocked position relative to the bracket, the limiting member can slide or rotate between the limiting position and the yielding position relative to the bracket, the driving member and the transmission member are both movably arranged on the bracket, the fixing seat is arranged on the bracket, the damper is arranged on the cover plate assembly, the first elastic member abuts between the limiting member and the bracket, and the second elastic member abuts between the connecting member and the bracket.

[0054] In other embodiments, the first elastic member is not provided, and the limiting member automatically returns to the limiting position from the yielding position only under its own gravity, or the limiting member can automatically return to the limiting position from the yielding position under the action of magnetic attraction; alternatively, the limiting member can automatically return to the limiting position from the yielding position under the combined action of the first elastic member, its own gravity, and magnetic attraction, and the automatic reset of the limiting member can also be achieved.

[0055] In other embodiments, the second elastic member can also be disposed between the driving member and the cover plate assembly. The driving member can be reset under the action of the second elastic member, and during the reset process, the driving member can drive the connecting member to automatically return to the locking position from the unlocking position through the transmission member; or the second elastic member is a torsion spring, which is disposed between the transmission member and the cover plate assembly. The transmission member can be reset under the action of the second elastic member, and during the reset process, the transmission member can drive the connecting member to automatically return to the locking position from the unlocking position and drive the driving member to reset.

[0056] In other embodiments, the cover plate assembly is an upper cover, or the cover plate assembly includes an upper cover and a seat ring.

[0057] As can be seen from the above description of the present invention, compared with the prior art, for a quick-release cover plate of the present invention, when the connecting member is in the locking position, the connecting member is inserted and matched with the rotating shaft along the axial direction of the rotating shaft to rotatably connect the cover plate assembly and the bracket together; when the connecting member is in the unlocking position, the connecting member is separated from the rotating shaft, so that the cover plate assembly is separated from the bracket, enabling the cover plate assembly of the present invention to be easily disassembled and assembled. Moreover, the overall structure of the present invention is simple, time-saving and labor-saving during assembly, and can reduce costs.
