A drainage adjusting structure of a wall-mounted water tank drainage valve

Abstract

This utility model relates to a drainage adjustment structure for a wall-mounted water tank drain valve. The drain valve body has a pull rod and a valve body base, with the pull rod connected to a valve disc. A bracket is provided at the drain outlet of the valve body base, and a rotatable adjustment frame is fitted into the core hole of the bracket. The adjustment frame is fixedly connected to a rotating rod placed in an opening in the pull rod, with the rotating head located at the opening at the top of the pull rod. The bracket has several diversion strips, and the adjustment frame has flow-blocking strips corresponding to the number of diversion strips. By rotating the rotating rod, the adjustment frame is rotated, causing the flow-blocking strips to overlap or stagger with the diversion strips, thus adjusting the drainage. This design offers the advantages of allowing users to independently adjust the flushing pressure and flushing uniformity, and reducing noise.

Description

Technical Field

[0001] This utility model relates to a drainage adjustment structure for an in-wall water tank drain valve. Background Technology

[0002] Existing wall-mounted water tanks have drain valves that allow for adjustable drainage volume, but the drainage pressure cannot be adjusted. This is especially problematic during flushing, where the drainage flow is concentrated and noisy. Furthermore, due to the concealed installation of wall-mounted water tanks, it is necessary to design a drainage adjustment device for the drain valve. This device should not only address the problems of existing technologies but also be easy to operate. Summary of the Invention

[0003] The purpose of this invention is to address the problems existing in the prior art by providing a drainage adjustment structure for a wall-mounted water tank drain valve that is easy to operate and allows for adjustable and uniform flushing.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A drainage adjustment structure for a wall-mounted water tank drain valve includes a valve body with a pull rod and a valve body base, the pull rod connecting to a valve disc; a bracket is provided at the drain outlet of the valve body base, and a rotatable adjustment frame is fitted into the core hole of the bracket, the adjustment frame being fixedly connected to a rotating rod placed in the opening of the pull rod, the rotating head of the rotating rod being located at the opening at the top of the pull rod; the bracket is provided with several diversion strips, and the adjustment frame is provided with flow-blocking strips corresponding to the number of diversion strips, the adjustment frame being rotated by rotating the rotating rod, causing the flow-blocking strips to overlap or stagger with the diversion strips to adjust the drainage.

[0005] Preferably, the bracket is provided with a locking ring, which has several latches that are connected to the hooks on the valve body base.

[0006] Preferably, the bracket is formed with a limiting shoulder, and the adjusting frame is formed with a limiting baffle. When the limiting baffle contacts the limiting shoulder, the flow-blocking strip of the adjusting frame overlaps with the flow-diverting strip of the bracket.

[0007] Preferably, a slot and a conical head are provided at the connection end between the rotating rod and the adjusting frame. The conical head has a slot. After the adjusting frame is inserted into the slot, the conical head of the rotating rod expands and locks the adjusting frame.

[0008] Furthermore, several diversion strips of the bracket are connected to the locking ring in a claw-like shape.

[0009] Furthermore, the limiting baffle of the adjustment frame and the flow-blocking strip form a claw-shaped structure.

[0010] The beneficial effect of this utility model is that the drain valve of the traditional wall-mounted water tank only controls and adjusts the drainage volume, but does not have the technology to control and adjust the flushing. This utility model uses a bracket and an adjustment frame set at the drain outlet. The adjustment frame is connected to a rotating rod, and the rotating head of the rotating rod is located at the opening at the top of the pull rod, allowing the user to adjust the flushing pressure and flushing uniformity independently, and reducing noise.

[0011] The following embodiments, in conjunction with the accompanying drawings, further illustrate the present invention. Attached Figure Description

[0014] Reference Figures 1 to 8This embodiment is a drainage adjustment structure for a wall-mounted water tank drain valve. The valve body of the drain valve is provided with a pull rod 1 and a valve body base 2, and the pull rod is connected to a valve plate 3. A bracket 5 is provided at the drain port 4 of the valve body base. A rotatable adjustment frame 6 is fitted into the core hole 7 of the bracket. The adjustment frame is fixedly connected to a rotating rod 9 placed in the opening 8 of the pull rod. The rotating head 10 of the rotating rod is located at the opening 11 at the top of the pull rod. The bracket is provided with 3 diversion strips 12, and the adjustment frame is provided with flow-blocking strips 13 corresponding to the number of diversion strips. By rotating the rotating rod, the adjustment frame is rotated so that the flow-blocking strips overlap or stagger with the diversion strips to adjust the drainage.

[0015] The bracket in this embodiment is provided with a locking ring 14, which has three latches 15. The latches are connected to the three hooks 16 on the valve body base. The three diversion strips of the bracket are connected to the locking ring in a claw shape.

[0016] In this embodiment, the bracket is formed with a limiting shoulder 17, and the adjusting frame is formed with a limiting baffle 18. The limiting baffle of the adjusting frame and the flow-blocking strip form a claw-shaped structure. When the limiting baffle and the limiting shoulder are in contact, the flow-blocking strip of the adjusting frame overlaps with the flow-diverting strip of the bracket.

[0017] In the above embodiments, the bracket is installed at the bottom of the valve body base via a snap-fit ​​mechanism. This can be replaced or modified as an equivalent technical solution and inventive concept of this utility model. Alternatively, the bracket can be directly formed or fixedly installed at the drain outlet of the valve body base. Then, the adjusting frame is rotatably mounted on the bracket. A slot 19 and a conical head 20 are provided at the connection end between the rotating rod and the adjusting frame. The conical head has a slot 21. After the adjusting frame is inserted into the slot, the conical head of the rotating rod expands and locks the adjusting frame. Thus, rotating the rotating rod head located at the opening at the top of the pull rod causes the rotating rod and the adjusting frame to rotate together around the axis, causing the flow-blocking strip of the adjusting frame to overlap or stagger with the flow-diverting strip of the bracket, thereby adjusting the flushing pressure and flushing uniformity of the drainage.

[0018] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
