[0017] In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-4 A quick-connect device without plugs / plugs includes a chassis body 1 and an adjustment plate 4. A circuit board body 6 and a quick-connect water channel 7 are fixedly and through-mounted on the outer side of the adjustment plate 4. The circuit board body 6 uses the circuit board and the connector wires on the circuit board to replace the pins on the traditional plugs / plugs to achieve quick circuit connection. The quick-connect water channel 7 enables quick installation and removal of water pipes. A quick-connect frame 2 is fixedly connected to the inner wall of the chassis body 1. A first opening groove 3 is provided on the inner side of the quick-connect frame 2. The adjustment plate 4 is slidably disposed on the inner wall of the quick-connect frame 2 and is connected to the first opening groove 3. The adjustment plate 4 and the quick-connect frame 2 together form a connection cavity 5. The connection of the circuit and the water channel is completed in this connection cavity. A second opening groove 9 is provided through-mounted on the outer side of the chassis body 1 and communicates with the connection cavity 5. A matching sealing cover 10 is snapped onto the second opening groove 9.

[0021] The quick-connect frame 2 has a connecting lug 201 fixedly welded to its outer side. The connecting lug 201 is fixedly connected to the chassis body 1 by fasteners, facilitating the assembly of the quick-connect frame 2 and allowing for disassembly during subsequent maintenance. The adjusting plate 4 slides in contact with the inner wall of the quick-connect frame 2. An adjusting screw 8 is threaded through the inner wall of the adjusting plate 4 near the bottom. The adjusting screw 8 also threaded through the quick-connect frame 2. When adjusting the size of the connecting cavity 5, the adjusting screw 8 is rotated. After the adjusting screw 8 threaded through the quick-connect frame 2, it drives the adjusting plate 4 to slide within the quick-connect frame 2, thereby adjusting the size of the connecting cavity 5. The main body 1 is fixedly connected to a fixed buckle 11 and a fixed arc-shaped rail 12 in sequence on the inner wall of the second opening groove 9. The outer side of the sealing cover 10 is fixedly connected to a movable arc-shaped rail 14 and a movable buckle 15. The movable arc-shaped rail 14 is limited and slidably engaged with the fixed buckle 11 on the inner wall of the second opening groove 9, and the movable buckle 15 is limited and slidably engaged with the fixed arc-shaped rail 12 on the inner wall of the second opening groove 9. A stop rib 13 is also fixedly provided on the inner surface of the fixed arc-shaped rail 12, abutting against the movable buckle 15. The movable buckle 15 is used to limit the front-to-back movement of the sealing cover 10, while the fixed buckle 11 is used for front-to-back limiting and preventing the sealing cover 10 from rotating axially. The stop rib 13 is used to indicate and limit the rotation endpoint. The movable arc-shaped rail 14 and the fixed buckle 11 cooperate to prevent the sealing cover 10 from rotating axially.

[0022] Based on the above structural design, during use, the size of the connecting cavity 5 can be adjusted by rotating the adjusting screw 8 to slide the adjusting plate 4 within the quick-connect frame 2. The sealing cover 10 can also be mated to the second opening slot 9 on the outside of the chassis body 1. The movable arc-shaped rail 14 and movable buckle 15 on the inner wall of the sealing cover 10 are mated and engaged in the gap between the fixed buckle 11 and the fixed arc-shaped rail 12. Then, rotating the sealing cover 10 causes the movable arc-shaped rail 14 to engage with the fixed buckle 11, and the movable buckle 15 to engage with the fixed arc-shaped rail 12, completing the installation of the sealing cover 10. The installation is then lifted into place by the stop rib 13.

[0023] It should be added that the contact surfaces of the movable arc rail 14 and the fixed buckle 11, as well as the contact surfaces of the movable buckle 15 and the fixed arc rail 12, are all equipped with sealing gaskets. The sealing gaskets can increase the sealing of the connection and also increase the friction, thus playing an auxiliary role in stabilizing and preventing slippage.

[0024] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.

[0025] In the description of this utility model, it should be understood that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the 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 referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
