Description

Technical Field

[0001] This utility model relates to the field of water level controller technology, specifically a water level controller. Background Technology

[0002] A water level controller is an automated device used to automatically monitor, adjust, and control water level. Its core function is to sense changes in water level and trigger preset switching actions to maintain the water level within a set range, or to meet specific needs such as water replenishment, drainage, overflow prevention, and dry burning prevention. It is widely used in industrial production, agricultural irrigation, domestic water supply, sewage treatment, and other scenarios.

[0003] The existing water level controller is installed by using a backplate to engage with the electrical guide rail. For ease of installation, the backplate is set in two sets: one set of fixed backplates and the other set of movable backplates. However, during disassembly, the movable backplates are easily blocked by the electrical guide rail, making it difficult for operators to apply force to them, resulting in disassembly difficulties. Moreover, when installed in a vibrating environment, the movable backplates are easily affected by vibration and may shift, reducing the tightness of the engagement with the electrical guide rail and causing the water level controller to be insecurely installed.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 7 This utility model provides a technical solution: a water level controller, including a water level controller body 1, a fixing block 5 disposed on the water level controller body 1, and two L-shaped protrusions 2 symmetrically disposed on the rear side of the water level controller body 1. A buckle 3 is slidably installed between the two L-shaped protrusions 2. A movable block 4 is provided at the top of the buckle 3. The movable block 4 and the fixing block 5 are on the same horizontal plane. The movable block 4 and the fixing block 5 cooperate to engage with the electrical guide rail, thereby installing the water level controller body 1 on the electrical guide rail. A square groove 19 is provided through the L-shaped protrusion 2. A pressing rod 6 is slidably connected inside the square groove 19. When it is necessary to disassemble the water level controller body 1 from the electrical guide rail, simply push the pressing rod 6 inward. The pressing rod 6 enters the empty groove 15 and presses the inclined surface 13, making... When the latch 3 moves downward, it drives the movable latch 4 downward, allowing the water level controller body 1 to be disassembled. When installed in a vibrating environment, the screw 16 can be rotated so that one end of the screw 16 enters the through hole 14. At this time, the latch 3 is fixed by the pressing rod 6, preventing the movable latch 4 from moving under vibration and ensuring that the water level controller body 1 is securely installed. The pressing rod 6 has a screw 16 connected to its internal thread. The end of the screw 16 near the latch 3 is smooth and has no thread. The side near the head has an external thread, which connects to the pressing rod 6. The latch 3 has slots 15 on both the left and right sides at the bottom. The inner wall of the slot 15 has an inclined surface 13 that matches the pressing rod 6. The latch 3 has a through hole 14 that communicates with the slot 15.

[0021] Among them, the end of the pressing rod 6 near the buckle 3 is provided with a limiting block 12. The limiting block 12 is used to limit the pressing rod 6 and prevent the pressing rod 6 from separating from the L-shaped protrusion 2. Both the L-shaped protrusion 2 and the buckle 3 are provided with a relief groove 11 that cooperates with the limiting block 12. The relief groove 11 is used to avoid the limiting block 12.

[0022] The water level controller body 1 has a fixed column 8 integrally formed on the rear side. The buckle 3 has an elastic arm 9 inside. One side of the elastic arm 9 abuts against the fixed column 8. When the buckle 3 moves downward under the action of external force, the elastic arm 9 will deform under the obstruction of the fixed column 8. When the buckle 3 is no longer subjected to external force, the elastic arm 9 will reset its deformation, thereby causing the buckle 3 to reset its movement.

[0023] The L-shaped protrusion 2 and the water level controller body 1 together form a sliding groove 17. The top of the L-shaped protrusion 2 is provided with sliders 10 that are slidably connected to the sliding groove 17. The sliders 10 can slide in the sliding groove 17 to prevent the buckle 3 from moving back and forth, which would cause the buckle 3 to separate from the water level controller body 1.

[0024] The buckle 3 is provided with a vertical block 7, and the rear side of the water level controller body 1 is provided with a stop block 18 for blocking the vertical block 7. The stop block 18 blocks the vertical block 7 to prevent the buckle 3 from moving too high and separating from the water level controller body 1.

[0025] Specifically, when installing the water level controller body 1, first, secure the fixing block 5 to the rear of the electrical guide rail. Then, press the water level controller body 1 close to the electrical guide rail. The electrical guide rail will press the movable block 4 downwards, causing it to move. The movable block 4 causes the latch 3 to move downwards, which in turn moves the elastic arm 9 downwards. The elastic arm 9 is deformed by the fixing post 8. When the water level controller body 1 is pressed against the electrical guide rail and the movable block 4 moves to the rear of the electrical guide rail, the elastic arm 9 will return to its original deformation, causing the latch 3 to return to its original position and move upwards. The latch 3 then moves the movable block 4 upwards, securing it to the rear of the electrical guide rail. The movable block 4 and the fixing block 5 work together to fix the water level controller body 1 onto the electrical guide rail, thus completing the installation. If installed in an area prone to vibration... In a vibrating environment, screw 16 can be rotated so that one end of screw 16 enters through hole 14 to lock buckle 3, preventing movable block 4 from moving under vibration and ensuring that the water level controller body 1 is firmly installed. If installed in an environment that will not be subject to vibration, screw 16 does not need to be rotated to facilitate subsequent disassembly. When it is necessary to disassemble the water level controller body 1, screw 16 is turned so that screw 16 is disengaged from through hole 14 and empty groove 15 and completely separated from buckle 3, releasing the lock on buckle 3. Then push pressing rod 6 inward. Pressing rod 6 enters empty groove 15 and presses inclined surface 13, causing buckle 3 to move downward. Buckle 3 drives movable block 4 to move downward, and movable block 4 separates from electrical guide rail. Then the water level controller body 1 can be disassembled.
