Abstract
Description
Technical Field
[0001] This utility model relates to the field of bathroom product technology, and more specifically, to a height-adjustable drain valve. Background Technology
[0002] Currently, drain valves on the market are divided into two categories: height-adjustable and height-non-adjustable. Adjusting the drain valve height via an adjustable frame is a common design. Existing drain valves typically use adjustable hooks to directly fix the adjustable frame. However, this direct fixation has the following problems: if the hook engagement is too loose, while adjustment is easy, it can cause the adjusted height to shift during use; if the hook engagement is too tight, while it won't shift during use, it will make adjustment difficult, resulting in a poor user experience.
[0003] In view of this, the inventors of this application have invented a height-adjustable drain valve. Utility Model Content
[0004] The purpose of this utility model is to provide a height-adjustable drain valve that is simple in structure, reasonable in design, easy to adjust, and will not shift.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a height-adjustable drain valve, comprising:
[0006] Valve body;
[0007] A fixing frame is fixed to the valve body, and the fixing frame includes a hook.
[0008] An adjustment frame, the adjustment frame including a plurality of longitudinally arranged locking teeth, the locking teeth being adapted to engage with the locking hook;
[0009] The latch, in conjunction with the fixed frame and the adjusting frame, engages and locks the locking teeth and hooks.
[0010] Furthermore, the fixed frame is provided with an elastic limiting part. The elastic limiting part has the hook on one side and a locking groove that cooperates with the buckle on the other side. When the buckle is located in the locking groove and corresponds to the hook, the elastic limiting part is fixed and the hook engages with the tooth to lock. When the buckle does not correspond to the hook or the buckle is disengaged from the locking groove, the elastic limiting part is pressed on one side of the locking groove, and the hook can disengage from the tooth.
[0011] Furthermore, the elastic limiting portion extends outward and is provided with a pressing portion.
[0012] Furthermore, the fixed frame is provided with a locking groove, and the latch slides in cooperation with the locking groove. When the latch slides to the first position of the locking groove, the hook can disengage from the tooth. When the latch slides to the second position of the locking groove, the hook engages with the tooth and locks.
[0013] Furthermore, the locking groove is arranged longitudinally, the second position is located above the first position, and the inner wall of the locking groove is provided with a limiting rib. When the latch slides to the second position, the latch and the limiting rib cooperate to limit the movement.
[0014] Furthermore, the latch is provided with a sliding groove that engages with the fixed frame, and the latch slides with the fixed frame through the sliding groove.
[0015] Furthermore, the adjusting frame is provided with a longitudinally extending connecting part, the locking teeth are provided on the connecting part, the fixing frame is provided with an installation guide groove that cooperates with the connecting part, and the locking hook is provided on the side wall of the installation guide groove.
[0016] Furthermore, there are two connecting parts, respectively located on both sides of the adjustment frame, and there are two mounting guide grooves and two corresponding latches.
[0017] Furthermore, the fixing frame is adapted to be mounted on the top of the valve body, the fixing frame is provided with fixing holes, and the valve body is provided with buckles that cooperate with the fixing holes for fixing.
[0018] By adopting the above technical solution, this utility model has the following advantages compared with the prior art:
[0019] This utility model features a height-adjustable drain valve. By adding a locking buckle to lock the hook and the tooth, the adjustment frame is fixed. In this way, the hook and the tooth can engage relatively loosely, which facilitates adjustment and prevents displacement during use. The overall structure is simple and ingeniously designed.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0035] It should be noted that in this utility model, the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element of this utility model must have a specific orientation, and therefore should not be construed as a limitation of this utility model. Example
[0036] Cooperate Figures 1 to 6 As shown, this utility model discloses a height-adjustable drain valve, which is used for draining toilet tanks. The height of the drain valve can be adjusted to adapt to different sizes of tanks. At the same time, the height adjustment structure of the drain valve can be locked to avoid difficulty in adjustment or displacement during use.
[0037] Cooperate Figures 1 to 6 As shown, a height-adjustable drain valve includes:
[0038] Valve body 10;
[0039] A fixing frame 20 is fixed to the valve body 10, and the fixing frame 20 includes a hook 211;
[0040] An adjustment frame 30 includes a plurality of longitudinally arranged locking teeth 32, which can be adapted to engage with the hook 211.
[0041] The latch 40 cooperates with the fixed frame 20 and the adjusting frame 30 to lock the locking teeth 32 and the hooks 211.
[0042] Cooperate Figures 1 to 2 As shown, the fixing frame 20 is fixed to the valve body 10 and is used to cooperate with the adjusting frame 30. Specifically, the fixing frame 20 is adapted to be placed on the top of the valve body 10. The fixing frame 20 is provided with a fixing hole 22, and the valve body 10 is provided with a buckle 11 that cooperates with the fixing hole 22 for fixing. The fixing frame 20 is fitted from the top to the outer periphery of the top of the valve body 10. Because the surface of the valve body 10 has curved and flat surfaces, and with the fixing hole 22 and the buckle 11 engaging for fixing, the fixing frame 20 is firmly fixed to the top of the valve body 10.
[0043] The adjusting frame 30 works in conjunction with the fixed frame 20 to adjust the overall height of the drain valve. Specifically, the height of the drain valve is adjusted by engaging the locking teeth 32 and hooks 211 at different longitudinal positions on the adjusting frame 30. The locking buckle 40 is used to engage and lock the hooks 211 and locking teeth 32. In this way, the engagement between the hooks 211 and locking teeth 32 can be designed to be less tight, making it easy to adjust. At the same time, after the position is adjusted, locking it with the locking buckle 40 can prevent it from shifting during use and ensure that it can be used normally.
[0044] Cooperate Figures 3 to 6 As shown, the fixed frame 20 is provided with an elastic limiting part 21. The elastic limiting part 21 has a hook 211 on one side and a locking groove 23 that cooperates with the buckle 40 on the other side. When the buckle 40 is located in the locking groove 23 and corresponds to the hook 211, the elastic limiting part 21 is fixed and the hook 211 engages with the tooth 32 to lock. When the buckle 40 does not correspond to the hook 211 or the buckle 40 disengages from the locking groove 23, the elastic limiting part 21 is pressed towards the side of the locking groove 23, and the hook 211 can disengage from the tooth 32.
[0045] The elastic limiting part 21 can swing slightly to both sides. When the latch 40 is not locked, press the elastic limiting part 21 and swing it towards the locking groove 23. The hook 211 on the other side of the elastic limiting part 21 will disengage or almost disengage from the tooth 32. At this time, the adjusting frame 30 can be adjusted up and down to a suitable position. Release the pressure on the elastic limiting part 21, and the elastic limiting part 21 will return to its original position. The hook 211 will engage with the tooth 32 at this time (this engagement is relatively loose). Then use the latch 40 to lock the hook 211 and the tooth 32 to prevent displacement. The locking mechanism of the latch 40 involves placing the latch 40 within the locking groove 23, corresponding to the position of the hook 211. This prevents the elastic limiting part 21 (the position of the hook 211) from swinging to the side of the locking groove 23, keeping it engaged with the tooth 32, thus locking the hook 211 and the tooth 32. Moving the latch 40 to another position or directly pulling the latch 40 out of the locking groove 23 allows the hook 211 to swing to the side of the locking groove 23, thereby disengaging or substantially disengaging the hook 211 from the tooth 32, thus allowing the position of the adjusting frame 30 to be adjusted.
[0046] In this embodiment, in order to facilitate pressing the elastic limiting part 21, the elastic limiting part 21 is provided with a pressing part 212 extending outward.
[0047] The locking groove 23 is designed as follows: The fixed frame 20 is provided with a locking groove 23, and the latch 40 slides in cooperation with the locking groove 23. When the latch 40 slides to the first position of the locking groove 23, the hook 211 can disengage from the tooth 32. When the latch 40 slides to the second position of the locking groove 23, the hook 211 engages with the tooth 32 and locks. When the latch 40 slides to the first position of the locking groove 23, the hook 211 disengages from the tooth 32, and the position of the adjusting frame 30 can be adjusted. When the latch 40 slides to the second position of the locking groove 23, the latch 40 and the hook 211 correspond, and the hook 211 cannot swing to one side of the locking groove 23. The hook 211 is limited by the latch 40 and engaged with the tooth 32 and locked.
[0048] Specifically, the locking groove 23 is arranged longitudinally, with the second position located above the first position. A limiting rib 24 is provided on the inner wall of the locking groove 23. When the latch 40 slides to the second position, the latch 40 engages with the limiting rib 24. The latch 40 moves upward along the locking groove 23, passing the limiting rib 24 to reach the second position. The latch 40 locks the hook 211 and the tooth 32. The limiting rib 24 engages with the latch 40, preventing the latch 40 from sliding downward from the second position and avoiding locking failure.
[0049] The latch 40 is provided with a sliding groove 41 that engages with the fixed frame 20, and the latch 40 slides with the fixed frame 20 through the sliding groove 41. The latch 40 is connected to the fixed frame 20 through the sliding groove 41 to prevent the latch 40 from disengaging from the fixed frame 20.
[0050] Cooperate Figures 5 to 6 As shown, the adjustment frame 30 and the fixed frame 20 cooperate as follows: The adjustment frame 30 is provided with a longitudinally extending connecting part 31, and the locking teeth 32 are provided on the connecting part 31. The fixed frame 20 is provided with an installation guide groove 25 that cooperates with the connecting part 31, and the hooks 211 are provided on the side wall of the installation guide groove 25. The adjustment frame 30 is connected to the fixed frame section through the connecting part 31. The design of the installation guide groove 25 makes the adjustment frame 30 more stable to install and easier to adjust. The locking teeth 32 are provided on the inner side of the connecting part 31, and the elastic limiting part 21 forms part of the installation guide groove 25. The hooks 211 and locking teeth 32 are designed to correspond to each other so that the two can be engaged. Furthermore, there are two connecting parts 31, respectively provided on both sides of the adjustment frame 30, and there are two installation guide grooves 25 and two locking buckles 40. The connecting parts 31, locking buckles 40, and elastic limiting parts 21 are all symmetrically arranged, making the entire frame structure more stable and easier to adjust.
[0051] When the height of the drain valve needs to be adjusted, slide the locking mechanism to the first position, press the elastic limiting parts 21 on both sides of the pressing part 212 to swing them inward (to the side of the locking groove 23), so that the hooks 211 on both sides are disengaged or basically disengaged from the teeth 32. Pull the adjusting frame 30 up and down to the desired position, then release the pressing of the elastic limiting part 21. The elastic limiting part 21 will reset and make the hooks 211 engage with the teeth 32. Finally, slide the lock 40 to the second position to lock the hooks 211 and the teeth 32. The adjusting frame 30 is fixed to prevent it from shifting during use.
[0052] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
