[0050] Example 1

[0051] The utility model discloses a drainage driving mechanism of a hidden water tank. The driving mechanism is used for driving a drainage valve in the hidden water tank to open and drain water.

[0052] Cooperate Figures 1 to 5 As shown, a drainage drive mechanism of a hidden water tank comprises:

[0053] Control element 10,

[0054] The bracket 30 is disposed in the hidden water tank 60, and the bracket 30 has a first mounting portion 31 and a second mounting portion 32;

[0055] A lifting assembly 40, wherein the lifting assembly 40 is disposed on the bracket 30 and connected to a valve core of a drain valve 61;

[0056] The linkage assembly 50 is connected to the control member 10, and the linkage assembly 50 includes a connecting rope 53 installed on the first mounting portion 31 or a push rod 55 installed on the second mounting portion 32. The control member 10 drives the linkage assembly 50 to drive the lifting assembly 40 through the connecting rope 53 or the push rod 55, so that the lifting assembly 40 pulls up the valve core of the drain valve 61 to drain the water.

[0057] The hidden water tank 60 has a receiving cavity, and the receiving cavity has a drain valve 61. The drain driving mechanism is arranged in the receiving cavity of the hidden water tank 60, and is used to drive the drain valve 61 to open and drain water. In the drain driving mechanism, the control member 10 is used to control the movement of the linkage assembly 50, and the bracket 30 is installed with a lifting assembly 40, and the lifting assembly 40 is connected to the drain valve 61, and can lift the valve core of the drain valve 61 to make the drain valve 61 drain water. The control member 10 drives the connecting rope 53 or the push rod 55 of the linkage assembly 50 to move, thereby driving the lifting assembly 40 to move, and lift the valve core of the drain valve 61 to make the drain valve 61 drain water.

[0058] Among them, the first mounting part 31 and the second mounting part 32 are simultaneously provided on the bracket 30, and the connecting rope 53 and the push rod 55 are installed respectively. The bracket 30 of the drainage drive mechanism can be optionally equipped with the connecting rope 53, and the drainage valve 61 is finally drained by the driving action of the connecting rope 53; or the bracket 30 can be optionally equipped with the push rod 55, and the drainage valve 61 is finally drained by the pushing of the push rod 55. If a bracket 30 can flexibly select different structures to realize the drainage drive, it has universality and flexible use.

[0059] The lifting assembly 40 includes a first linkage part that is linked with the connecting rope 53 and a second linkage part that is linked with the push rod 55. Furthermore, the first linkage part and the second linkage part are provided on the lifting assembly 40 at the same time. When the connecting rope 53 or the push rod 55 is assembled on the corresponding bracket 30, the lifting assembly 40 has a structure (the first linkage part and the second linkage part) that is linked with the connecting rope 53 or the push rod 55. The lifting assembly 40 is also universal and flexible to use.

[0060] The design of the lifting assembly 40 is as follows: the lifting assembly 40 includes a drainage rocker arm 41 and a drainage lifting rod 42. The drainage rocker arm 41 is rotatably disposed on the bracket 30, and the drainage rocker arm 41 is connected to the linkage assembly 50. The drainage lifting rod 42 is rotatably connected to the drainage rocker arm 41 and is connected to the valve core of the drainage valve 61. The first linkage part and the second linkage part are both disposed on the drainage rocker arm 41.

[0061] The top of the drain swing rod 41 is rotatably connected to the bracket 30, and the middle part is provided with a first linkage part and a second linkage part, and the bottom end is rotatably connected to the drain lifting rod 42. The top of the drain lifting rod 42 is rotatably connected to the drain swing rod 41, and the bottom end is connected to the valve core of the drain valve 61. The connecting rope 53 of the linkage assembly 50 drives the bottom end of the drain swing rod 41 to swing upward through the first linkage part or the push rod 55 through the second linkage part, thereby driving the drain lifting rod 42 to pull up the valve core of the drain valve 61, and the drain valve 61 is opened to drain water.

[0062] The drain valve 61 includes the functions of full drain and half drain. Correspondingly, the lifting assembly 40, the linkage assembly 50, the pressure rod 20 and the control member 10 are respectively provided with two groups, which are used to drive the drain valve 61 to open the half drain function and the full drain function respectively. The two sets of mechanisms are independent of each other and do not interfere with each other. When the two sets of lifting assemblies 40 are correspondingly mounted on the bracket 30, a latch 43 is fixed between the two sets of lifting assemblies 40, so that the two sets of lifting assemblies 40 are fixed on the bracket 30. The latch 43 is removed, and the lifting assembly 40 can be removed from the bracket 30, which is convenient for disassembly and assembly.

[0063] The control member 10 is a drainage button disposed on the panel 62 of the hidden water tank 60. Pressing the drainage button drives the connecting rope 53 or the push rod 55 of the linkage assembly 50 to drive the lifting assembly 40 to be linked.

[0064] In this embodiment, the linkage assembly 50 is designed with a connecting rope 53. Specifically, the linkage assembly 50 includes a pressure rod 20, a pressure rod box 51, a swing rod 52 and the connecting rope 53. The swing rod 52 is swingably arranged in the pressure rod box 51. One end of the pressure rod 20 is connected to the control member 10, and the other end extends into the pressure rod box 51 and is connected to the swing rod 52. One end of the connecting rope 53 is connected to the swing rod 52, and the other end is connected to the lifting assembly 40. The control member 10 drives the pressure rod 20 to move and drive the swing rod 52 to swing, and then pulls the connecting rope 53 to drive the lifting assembly 40 to pull up the valve core of the drain valve 61.

[0065] One end of the pressure rod 20 is connected to the drainage button, and the other end is abutted against an elastic reset member 21. The control member 10 (pressing the drainage button) drives the pressure rod 20 to move along its axial direction, thereby driving the swing rod 52 to swing. The swing of the swing rod 52 pulls the connecting rope 53, thereby driving the lifting assembly 40 to pull up the valve core of the drainage valve 61, so that the drainage valve 61 drains water; after the pressure of pressing the drainage button is removed, the elastic reset member 21 drives the pressure rod 20 and the button to reset (the pressure rod 20 resets in the opposite direction along the axial direction), driving the swing rod 52 to swing in the opposite direction, and the tension of the swing rod 52 on the connecting rope 53 is relaxed. The valve core of the drainage valve 61 and the lifting assembly 40 naturally fall and reset under the action of weight, and the drainage valve 61 is closed and no longer drains water. At the same time, the connecting rope 53 is also pulled back to the original position (the connecting rope 53 is always in a tensioned state), wherein the elastic reset member 21 is a compression spring.

[0066] The pressure rod box 51 is detachably connected to the back of the water tank panel 62. The pressure rod box 51 is assembled by an upper cover 511 and a lower cover 512 and locked by screws. The pressure rod 20 is installed in the pressure rod box 51, one end of which extends out of the pressure rod box 51 and is connected to the back of the drainage button on the panel 62, and the other end is abutted against the elastic reset member 21 and located in the pressure rod box 51. One end of the elastic reset member 21 abuts against the pressure rod 20, and the other end abuts against the pressure rod box 51.

[0067] The swing rod 52 is swingably installed in the pressure rod box 51, that is, the swing rod 52 can swing relative to the pressure rod box 51. The swing rod 52 is connected to the pressure rod 20. When the control part 10 drives the pressure rod 20 to move axially, the pressure rod 20 drives the swing rod 52 to swing relative to the pressure rod box 51. The swing of the swing rod 52 then pulls the connecting rope 53.

[0068] In this embodiment, the specific connection structure of the swing rod 52 is as follows: the middle part of the swing rod 52 is rotatably connected to the pressure rod box 51, one end of the swing rod 52 is rotatably connected to the middle part of the pressure rod 20, and the other end is connected to the connecting rope 53. When the pressure rod 20 moves axially, the end of the swing rod 52 connected to it moves accordingly, thereby driving the other end connected to the connecting rope 53 to swing in the opposite direction, thereby pulling the connecting rope 53.

[0069] Cooperate Figures 2 to 5 As shown, the linkage assembly 50 includes a guide tube 532, the connecting rope 53 movably passes through the guide tube 532, the bracket 30 is provided with a fixing buckle 311 which is buckled therewith, the fixing buckle 311 and the bracket 30 are enclosed to form the first mounting portion 31 in the shape of a hole, one end of the guide tube 532 is fixed in the first mounting portion 31, and the connecting rope 53 passes through the guide tube 532 and the first mounting portion 31 to be connected to the lifting assembly 40.

[0070] The guide tube 532 is a hard tube, which plays a guiding and limiting role for the connecting rope 53. One end of the guide tube 532 is connected and fixed to the pressure rod box 51, and the other end is connected and fixed to the bracket 30. Specifically, one end of the guide tube 532 is locked and fixed between the upper cover 511 and the lower cover 512 of the pressure rod box 51, and the other end is installed and fixed in the first mounting portion 31 of the bracket 30. The structure of the first mounting portion 31 is as follows: the bracket 30 is provided with a connecting buckle 312, and a fixing buckle 311 that is detachably fixed to the connecting buckle 312, and the fixing buckle 311 and the connecting buckle 312 are enclosed to form a fixing hole, which is the first mounting portion 31. Furthermore, the first mounting portion 31 and the pressure rod box 51 are adapted to the outer wall of the guide tube 532 through a concave-convex structure, so that the guide tube 532 is further ensured to be firmly installed. The connecting rope 53 is a steel wire rope, which passes through both ends of the guide tube 532 and can move inside the guide tube 532. Both ends of the connecting rope 53 pass through both ends of the guide tube 532 and are respectively connected to the lifting component 40 and the swing rod 52.

[0071] A limit block 531 is respectively provided at both ends of the connecting rope 53. The first linkage part is a limit slot 44 that cooperates with the connecting rope 53. The connecting rope 53 is limitedly cooperated with the limit slot 44 through the limit block 531. The limit slot 44 has a slit for the connecting rope 53 to be inserted. The connecting rope 53 is movably engaged in the limit slot 44 through the slit. The limit block 531 is engaged outside the limit slot 44. The cooperation of the limit slot 44 and the limit block 531 prevents the connecting rope 53 from accidentally detaching from the lifting assembly 40. The connecting rope 53 has the same connection and cooperation structure with the swing rod 52 and the lifting assembly 40, which will not be described in detail.

[0072] Example 2

[0073] Cooperate Figure 6 to Figure 7 As shown, the linkage assembly 50 of this embodiment adopts the design of a connecting rope 53, and the main difference between it and Example 1 is that the connection structure of the swing rod 52 is different. In this embodiment, the specific connection structure of the swing rod 52 is as follows: the linkage assembly 50 includes a rotating disk 54, the inner wall of the rotating disk 54 is spirally matched with the outer wall of the pressure rod 20, and the swing rod 52 is arranged along the radial direction of the rotating disk 54, one end of the swing rod 52 is connected to the rotating disk 54, and the other end is connected to the connecting rope 53.

[0074] The rotating disk 54 is movably sleeved on the outer periphery of the pressure rod 20, and the inner wall of the rotating disk 54 is spirally matched with the outer wall of the pressure rod 20, that is, the inner wall of the rotating disk 54 and the outer wall of the pressure rod 20 cooperate with each other through the spiral guide strip 541 and the spiral groove that cooperate with each other. In this way, when the pressure rod 20 moves axially, the rotating disk 54 is driven to spirally move relative to the pressure rod 20 along the axis of the pressure rod 20, and the swing rod 52 is arranged along the radial direction of the rotating disk 54, one end of which is connected to the outer wall of the rotating disk 54, and the other end is connected to the connecting rope 53. When the rotating disk 54 spirally moves, it drives the swing rod 52 to spirally move accordingly, thereby pulling the connecting rope 53.

[0075] Example 3

[0076] Cooperate Figures 8 to 11 As shown, this embodiment is an embodiment in which the bracket 30 is equipped with a push rod 55 to drive the lifting component 40 and the drain valve 61 to drain water. Compared with the embodiment 1, the main difference is the structure of the linkage component 50.

[0077] In this embodiment, the second mounting portion 32 of the bracket 30 is an axle tube 321 provided on the bracket 30, and the linkage assembly 50 includes a pressure rod 20 and a push rod 55. One end of the pressure rod 20 is connected to the control member 10, and the other end is connected to the push rod 55. The push rod 55 is installed in the axle tube 321. The side wall of the push rod 55 is provided with a push block 551. The second linkage portion is an arc-shaped driving portion 45 that abuts against the push block 551. The control member 10 drives the pressure rod 20 to move, drives the push block 551 to move, and drives the lifting assembly 40 through the arc-shaped driving portion 45 to pull up the valve core of the drain valve 61.

[0078] The structure of the bracket 30 and the lifting assembly 40 is consistent with the structure in Example 1. The control part 10 is a drainage button. One end of the pressure rod 20 is connected to the back of the drainage button, and the other end is embedded in the push rod 55. Pressing the drainage button drives the pressure rod 20 and the push rod 55 to move axially.

[0079] One end of the push rod 55 is sleeved on the end of the pressure rod 20, and the other end is installed in the shaft tube 321 of the bracket 30 through an elastic reset member 21. The elastic reset member 21 is a compression spring, one end of the compression spring is against the push rod 55, and the other end is against the inner wall of the shaft tube 321. When the drainage button is pressed to drive the pressure rod 20 and the push rod 55 to move axially, the elastic reset member 21 is compressed. After the pressure of the drainage button is removed, the push rod 55 and the pressure rod 20 move in the opposite direction and reset under the action of the elastic reset member 21.

[0080] A push block 551 is provided on the side wall of the push rod 55, and the drain rocker arm 41 is provided with an arc-shaped driving portion 45 (second linkage portion) abutting against the push block 551. When the push block 551 moves axially with the push rod 55, the drain rocker arm 41 is driven to swing through the arc-shaped driving portion 45, thereby pulling up the drain lifting rod 42 and the valve core of the drain valve 61, so that the drain valve 61 drains water.

[0081] The side wall of the shaft tube 321 is provided with a strip through hole 33, and the push block 551 on the side wall of the push rod 55 passes through the strip through hole 33 and abuts against the arc-shaped driving part 45. At the same time, the strip through hole 33 also plays a guiding and limiting role, making the axial movement of the push rod 55 and the pressure rod 20 more stable.

[0082] The drainage drive mechanism of the hidden water tank of the utility model has a bracket 30 with a first mounting portion 31 and a second mounting portion 32 reserved therefor, and a lifting component 40 is provided with a first driving portion and a second driving portion. Different assembly structures can be flexibly selected according to needs, and the use is flexible and universal. In addition, the design of the entire drainage drive mechanism is reasonable, compact, simple and effective, and convenient to disassemble and assemble.

[0083] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
