Description

Technical Field

[0001] This utility model relates to the field of toilet drain valve technology, and in particular to a quick installation clamp for a grooved automatic toilet drain valve. Background Technology

[0002] The automatic drain valve for grooved toilets is a drainage control device installed at the bottom of the water tank. It usually adopts a float ball or mechanical linkage structure and automatically opens to drain water based on changes in water level or manual triggering. It can quickly reset after flushing to prevent water waste. It is suitable for water tank systems in grooved public toilets and features leak-proof and durable characteristics, which can improve flushing efficiency and reduce maintenance costs.

[0003] Existing toilet drain valves are mainly fixed to the bottom of the water tank by plastic nuts during installation. This single fixing method lacks an auxiliary clamping and positioning structure. Because plastic material is prone to aging and deformation, and is affected by long-term water flow impact and frequent operation, the threads of the nuts are prone to wear and loosening, causing the drain valve to gradually shift or even fall off. This not only affects the flushing effect, but may also cause problems such as water tank leakage, requiring frequent inspection and maintenance.

[0004] Therefore, to address the problem that existing toilet drain valves use plastic nuts to position them against the water tank during installation, lack an auxiliary clamping and positioning structure, and are prone to loosening after long-term use, a grooved automatic toilet drain valve quick installation clamp can be designed. Utility Model Content

[0005] To overcome the problem that existing toilet drain valves use plastic nuts to position them against the water tank during installation, lack an auxiliary clamping and positioning structure, and are prone to loosening after long-term use.

[0006] The technical solution of this utility model is as follows: a quick-installation clamp for a grooved automatic drain valve for latrines, including a water tank and a clamping plate. The drain valve body is installed inside the water tank. A fixing plate is provided at the bottom of the water tank. Multiple circumferentially distributed sliding grooves are opened at the bottom of the fixing plate. A slider is slidably connected inside the sliding groove. A connecting rod is installed at the bottom of the slider. The clamping plate is fixed at the end of the connecting rod. A housing is rotatably connected to the outside of the fixing plate. Multiple circumferentially distributed limiting grooves are opened at the bottom of the housing. The connecting rod is slidably connected to the limiting grooves. An adjustment mechanism is provided at the bottom of the water tank. A positioning mechanism is provided on the adjustment mechanism.

[0007] Preferably, by setting the outer shell, when the outer shell is rotated, the limiting groove on its surface will squeeze the connecting rod, thereby causing the connecting rod to drive the slider to slide inside the sliding groove, thereby achieving concentric adjustment of multiple clamping plates, so that the clamping plates can clamp the pipe of the drain valve body, thereby achieving auxiliary positioning of the drain valve body. This solves the problem that the existing toilet drain valves are positioned with plastic nuts to the water tank during installation, lacking an auxiliary clamping and positioning structure, and are prone to loosening after long-term use.

[0008] Preferably, the adjustment structure includes a telescopic component and a rotating component. The telescopic component is used to drive the positioning mechanism to move left and right, and the rotating component is used to rotate the telescopic component.

[0009] Preferably, the telescopic assembly includes positioning plates and lead screws. Two sets of positioning plates are installed at the bottom of the water tank, and each set of positioning plates is threaded with a lead screw.

[0010] Preferably, the rotating assembly includes a knob and a mating groove; the knob is fixed on the lead screw, and the knob has a mating groove.

[0011] Preferably, the positioning mechanism includes a clamping component and a limiting component, wherein the clamping component is used to limit the rotation of the housing, and the limiting component is used to limit the clamping component.

[0012] Preferably, the clamping assembly includes a connector and a limiting plate; the connector is mounted on the end of the lead screw, and the limiting plate is rotatably connected to the connector.

[0013] Preferably, the limiting component includes a positioning block and a positioning groove; two positioning blocks are installed on the top of the limiting plate, and a positioning groove is opened at the bottom of the water tank corresponding to the position of the positioning block, and the positioning block and the positioning groove are slidably connected.

[0014] The beneficial effects of this utility model are:

[0015] By using clamps to assist in positioning the drain valve body, the overall installation strength and stability of the drain valve body can be significantly improved. This design effectively avoids the risk of displacement of the drain valve body due to vibration or external forces during long-term use, thereby greatly reducing the possibility of loosening and leakage. At the same time, the auxiliary fixing effect of the clamps makes the drain valve body more secure and reliable during operation, extending the service life of the equipment. In addition, this reinforcement method can reduce the frequency of daily maintenance, reduce maintenance costs, bring users a more durable and safer user experience, and ensure the long-term stable operation of the system.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5 This utility model provides an embodiment of a quick-installation clamp for a grooved automatic drain valve for latrines, including a water tank 1 and a clamping plate 7. The drain valve body 2 is installed inside the water tank 1. A fixing plate 3 is provided at the bottom of the water tank 1. Multiple circumferentially distributed sliding grooves 4 are opened at the bottom of the fixing plate 3. A slider 5 is slidably connected inside the sliding grooves 4. A connecting rod 6 is installed at the bottom of the slider 5. The clamping plate 7 is fixed at the end of the connecting rod 6. A housing 8 is rotatably connected to the outside of the fixing plate 3. Multiple circumferentially distributed limiting grooves 9 are opened at the bottom of the housing 8. The connecting rod 6 is slidably connected to the limiting grooves 9. An adjustment mechanism is provided at the bottom of the water tank 1. A positioning mechanism is provided on the adjustment mechanism. By rotating the housing 8, the limiting grooves 9 on its outer wall will generate an interaction force with the connecting rod 6, pushing the connecting rod 6 to move, thereby driving the slider 5 to move linearly along the sliding grooves 4. This achieves synchronous radial adjustment of multiple clamping plates 7. This linkage mechanism enables the clamping plates 7 to accurately clamp the pipe of the drain valve body 2 and complete the auxiliary positioning of the drain valve body 2.

[0024] Please see Figure 1 and Figure 5 In this embodiment, the adjustment structure includes a telescopic component and a rotating component. The telescopic component is used to drive the positioning mechanism to move left and right, and the rotating component is used to rotate the telescopic component. The telescopic component includes a positioning plate 101 and a lead screw 102. Two sets of positioning plates 101 are installed at the bottom of the water tank 1. Each set of positioning plates 101 is threadedly connected to a lead screw 102. By setting the lead screw 102, when rotating the lead screw 102, the lead screw 102 can move left and right along the positioning plate 101. The rotating component includes a knob 103 and a docking groove 104. The knob 103 is fixed on the lead screw 102. The knob 103 has a docking groove 104. By setting the docking groove 104, which is hexagonal, the operator can rotate the knob 103 with a hexagonal screw, thereby driving the lead screw 102 to rotate.

[0025] Please see Figure 1 and Figure 5In this embodiment, the positioning mechanism includes a clamping component and a limiting component. The clamping component is used to limit the rotation of the outer shell 8, and the limiting component is used to limit the clamping component. The clamping component includes a connector 111 and a limiting plate 112. The connector 111 is installed at the end of the lead screw 102, and the limiting plate 112 is rotatably connected to the connector 111. By setting the connector 111 and the limiting plate 112, the lead screw 102 drives the limiting plate 112 to move synchronously when it moves. The limiting component includes a positioning block 113 and a positioning groove 114. Two positioning blocks 113 are installed on the top of the limiting plate 112, and a positioning groove 114 is opened at the bottom of the water tank 1 corresponding to the position of the positioning block 113. The positioning block 113 and the positioning groove 114 are slidably connected. By setting the positioning block 113 and the positioning groove 114, the limiting plate 112 can be kept horizontal under the cooperation of the rotatable connection of the connector 111, and the rotation of the lead screw 102 can be prevented from driving the limiting plate 112 to rotate.

[0026] During operation, rotating the outer casing 8 causes the limiting groove 9 at its bottom to press against the connecting rod 6, forcing the connecting rod 6 to drive the slider 5 to slide radially within the sliding groove 4 of the fixed plate 3. Multiple connecting rods 6 move synchronously, causing all clamping plates 7 to move concentrically to clamp or release the pipe of the drain valve body 2, thus achieving auxiliary positioning. During adjustment, rotating the knob 103 drives the lead screw 102 to move axially on the positioning plate 101. The lead screw 102 drives the end connector 111 and the limiting plate 112 rotatably connected to it to move horizontally. When the limiting plate 112 moves to press against the outside of the outer casing 8, it can restrict the rotation of the outer casing 8, thereby locking the clamping position of the clamping plate 7 and ensuring that the drain valve body 2 is installed securely.

[0027] Through the above steps, when the outer shell 8 rotates, the limiting groove 9 on its outer surface will form a forced motion pair with the connecting rod 6, forcing the connecting rod 6 to move. This displacement is converted into linear motion through the guiding cooperation of the slider 5 and the sliding groove 4, thereby driving the multiple clamping plates 7 arranged in a ring to move radially synchronously. This linkage mechanism enables all clamping plates 7 to adaptively clamp around the drain valve body 2 pipe as the center, ultimately achieving precise positioning and stable support of the drain valve body 2. This solves the problem that existing toilet drain valves use plastic nuts to position them with the water tank 1 during installation, lack auxiliary clamping and positioning structures, and are prone to loosening after long-term use.
