Description

Technical Field

[0001] The invention relates to the technical field of toilet water tank drain valves, and in particular to a water level regulating mechanism with a self-locking function. Background Art

[0002] The drainage volume of the internal cavity of the existing water tank drain valve is generally adjusted by controlling the size of the opening on the control valve body. The device usually opens a drainage hole on one side of the drainage cavity of the drain valve, and multiple clamping teeth are arranged on both sides of the drainage hole. A card is also designed, and two cantilevered elastic arms are arranged on the card. The card is installed in the drainage hole, and the elastic arms of the card are buckled in the clamping teeth on both sides of the drainage hole. When the water level and water volume inside the drain valve need to be adjusted, a certain force is applied to the card to force the elastic arms of the card to undergo elastic deformation, so that the card and the clamping teeth on both sides of the drainage hole are out of the buckling state, so that the card can produce a position change on the drainage hole. At this time, the size of the drainage hole blocked by the card also changes. The water in the drainage valve cavity changes due to the change in the size of the drainage hole, and the speed and time of the descent of the water also change, thereby affecting the speed and time of the descent of the float in the cavity, and finally causing the water volume discharged by the drain valve to change. However, there are the following shortcomings in actual use: First, the fit between the elastic arm of the card and the clamping teeth of the drainage hole cannot be too tight, otherwise it is difficult to push and adjust the relative position of the card and the drainage hole; nor can it be too loose, otherwise the card is easy to loosen and the relative position of the card and the drainage hole cannot be locked and adjusted. Since the drain valve generally needs to be adjusted to a specific height before being delivered to the user; during transportation or under the action of external force, the position of the water level adjustment card and the drain hole may accidentally slide, causing the pre-set position to change and the drainage volume to change accordingly. Too much drainage will cause waste, and too little drainage will affect the flushing effect of the toilet. Summary of the invention

DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and the best embodiments.

[0028] As shown in the figure, the present invention comprises a partition 1, an adjustment card 2 arranged on one side of the partition 1, and an adjustment lock 3, wherein the adjustment card 2 is slidably connected to the partition 1 in the longitudinal direction, and in this example, a hand-held surface is provided at the lower part of the outer surface of the adjustment card 2 for the convenience of the user to push and adjust, and the adjustment lock 3 is elastically connected to the partition 1 through an elastic member, and the adjustment lock 3 is clamped with the adjustment card 2 by the restoring force of the elastic member. The present invention has a scientific and reasonable structural design, convenient operation, and stable performance. When the adjustment lock 3 is not acted upon by an external force, it is in a locked state with the adjustment card 2, so that the adjustment card 2 is always in a set position and cannot slide away from the locking of the adjustment lock 3, thereby avoiding the "displacement" of the adjustment card 2 during non-human use, work, and transportation, and ensuring that the water volume of the drain valve does not change.

[0029] According to the above embodiment, preferably, the partition 1 includes a vertical plate 1.3, a drainage hole 1.1 is provided on the vertical plate 1.3, a card slot 1.2 is provided on the vertical plate 1.3 above the drainage hole 1.1, the adjustment card 2 is a U-shaped structure, the adjustment card 2 includes an integrally formed adjustment plate and an elastic arm 2.1, a plurality of slide buckles 2.2 are provided along the longitudinal direction on the inner wall of the adjustment plate, and the adjustment plate is subjected to the restoring force of the elastic arm 2.1 so that the slide buckles 2.2 are located in the card slot 1.2. In this example, the elastic member includes two oppositely arranged spring pieces 3.1, one end of the spring piece 3.1 is fixedly connected to the adjustment lock 3, and the other end of the elastic piece abuts against the two sides of the fixing hole of the vertical plate 1.3. The adjustment card 2 is provided with a plurality of latch teeth 2.3 along the longitudinal direction, and the adjustment lock 3 includes a plurality of locking teeth 3.2 that are adapted to the shape of the latch teeth 2.3, and the locking teeth 3.2 of the adjustment lock 3 are engaged in the latch teeth 2.3 of the adjustment card 2 by the restoring force of the elastic member.

[0030] According to the above embodiment, preferably, a fixing hole is provided on the vertical plate 1.3, and the adjustment lock 3 includes two oppositely arranged buckles 3.3, and the adjustment lock 3 is clamped with the vertical plate 1.3 at the position of the fixing hole through the buckles 3.3. In this example, the two buckles 3.3 of the adjustment lock 3 are clamped with the vertical plate 1.3 of the partition 1 to prevent the adjustment lock 3 from being separated from the fixing hole 1.4 of the partition 1.

[0031] The working principle of this patent is as follows: when there is no external force applied to the adjustment lock 3, or the applied force cannot completely disengage the locking teeth 3.2 of the adjustment lock 3 from the locking teeth 2.3 of the adjustment card 2, the adjustment card 2 is always in a locked state with the adjustment lock 3, that is, the adjustment card 2 cannot slide on the partition 1, and the adjustment card 2 and the drainage hole 1.1 of the partition 1 are in a fixed position. At this time, the position change of the adjustment card 2 caused by transportation can be effectively avoided, thereby avoiding changes in the drainage volume of the drain valve.

[0032] When the water volume needs to be adjusted, an external force toward the inside of the partition is first applied to the adjustment lock 3, so that the adjustment lock 3 moves inward under the action of the external force. During the inward movement of the adjustment lock 3, the two spring pieces 3.1 of the adjustment lock 3 are elastically deformed to accumulate elastic potential energy. During the inward movement of the adjustment lock 3, the locking tooth 3.2 begins to move away from the locking tooth 2.3 of the adjustment card 2. When the adjustment lock 3 moves to the set position under the action of the external force, the locking tooth 3.2 completely disengages from the locking tooth 2.3 of the adjustment card 2, that is, the adjustment lock 3 and the adjustment card 2 are in a yielding state.

[0033] Keep the external force on the adjustment lock 3 unchanged, and apply a downward / upward external force on the adjustment card 2 to adjust the size of the drainage hole area, thereby changing the drainage volume. During the sliding of the adjustment card 2, the slider 2.2 on the adjustment card 2 moves away from the elastic arm 2.1, that is, the elastic arm 2.1 of the adjustment card 2 undergoes elastic deformation. When the slider 2.2 of the adjustment card 2 slides to the top of the card slot 1.2 of the partition 1, the slider 2.2 and the card slot 1.2 are in a non-contact state. Under the elastic deformation of the elastic arm 2.1, the slider 2.2 of the adjustment card 2 moves into the card slot 1.2. Continue to apply downward / upward external force on the adjustment card 2, so that the slider 2.2 of the adjustment card 2 repeatedly slides out and snaps in from the card slot 1.2 of the partition 1. The jerking feeling produced by this sliding out and snapping in can enable the operator to clearly feel the change in the adjustment position.

[0034] When the adjustment card 2 is adjusted to the desired position, the external force applied to the adjustment card 2 and the adjustment lock 3 is stopped. Since the adjustment card 2 loses the downward / upward external force, the adjustment card 2 stops at a fixed position. Since the spring piece 3.1 of the adjustment lock 3 gathers a certain elastic potential energy under the action of the external force, elastic deformation is generated. At this time, the external force applied to the adjustment lock 3 is removed, and the spring piece 3.1 of the adjustment lock 3 begins to restore the deformation, so that the adjustment lock 3 moves outward, driving the locking tooth 3.2 on the adjustment lock 3 to move toward the locking tooth 2.3 of the adjustment card 2. When the spring piece 3.1 of the adjustment lock 3 is completely restored to the initial state, the locking tooth 3.2 has completely entered the locking tooth 2.3 of the adjustment card 2, that is, the adjustment card 2 and the adjustment lock 3 are in a locked state.

[0035] If the outside world only applies external force to the adjustment card 2, since the adjustment lock 3 is in the absence of external force, the locking teeth of the adjustment lock 3 will then lock the locking teeth 2.2 of the adjustment card 2, and the adjustment lock 3 itself is fixed on the partition 1, so that the relative positions of the adjustment card 2 and the partition 1 cannot change, thereby avoiding the adjustment card from "moving" during non-human use, work and transportation.

[0036] According to the above embodiment, preferably, the vertical cross-section of the card slot 1.2 and the slider 2.2 is a trapezoidal structure, and the card slot 1.2 and the slider 2.2 both include mutually adapted matching inclined surfaces, and in this example, the angle between the matching inclined surface and the vertical surface is greater than 90 degrees. Since the card slot of the partition 1 is designed as a slope greater than 90 degrees, the slider 2.2 of the adjustment card 2 slides along the slope of the card slot 1.2 of the partition 1 under the action of external force.

[0037] According to the above embodiment, preferably, the partition 1 is outer-connected with an upper frame 4, the upper frame 4 is provided with an adjustment opening relative to the position of the adjustment card 2, and the upper frame 4 is provided with a locking opening relative to the position of the adjustment lock 3. The outer end of the adjustment lock 3 extends outward through the locking opening, and the distance between the outer end of the adjustment lock 3 and the outer surface of the upper frame 4 is less than the depth of the latch teeth 2.3. If the adjustment lock 3 moves inward only due to the extrusion between objects, since the distance between the outer end of the adjustment lock and the outer surface of the upper frame is less than the depth of the latch teeth, that is, the protruding height of the adjustment lock 3 on the upper frame 4 is less than the locking teeth 3.2 of the adjustment lock 3 can be completely separated from the latch teeth 2.3 of the adjustment card 2, so that due to the protection of the upper frame 4, the adjustment lock cannot continue to move inward, and at this time, the locking teeth of the adjustment lock are still in a state of engagement with the latch teeth of the adjustment card, avoiding the adjustment lock 3 and the adjustment card 2 from being unlocked, thereby effectively preventing the adjustment card and the drainage hole from accidentally sliding during transportation or under the action of external forces.

[0038] The structural design of the present invention is scientific and reasonable, the operation is convenient, and the performance is stable. When the adjustment lock 3 is not acted upon by external force, it is in a locked state with the adjustment card 2, so that the adjustment card 2 is always in a set position and cannot slide out of the lock of the adjustment lock 3, thereby avoiding the adjustment card 2 from "running out of position" during non-human use, work, and transportation, and ensuring that the water volume of the drain valve does not change.

[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
