Description

TECHNICAL FIELD

[0001] The technical scheme relates to the technical field of circulating pumps, and particularly relates to a control box turning structure and a circulating pump. BACKGROUND

[0002] A circulating pump is a mechanical device used for transporting or circulating fluid. The working principle of the circulating pump is that a motor or other type of prime mover drives the rotation of an impeller in the pump body, thereby generating centrifugal force to suck liquid from the inlet of the pump and push it to the outlet, forming a continuous fluid circulation.

[0003] For example, Chinese Patent CN102182694A discloses a circulating pump comprising a circulating pump body and a control mechanism. The circulating pump body is composed of a brushless DC motor, an impeller, a pump body, and a motor shell. The control mechanism is a sensorless frequency converter controller group. The sensorless frequency converter controller is connected to the brushless DC motor. The shaft of the brushless DC motor is connected to the impeller, which is arranged in the pump body. The pump body is provided with a water inlet and a water outlet. The brushless DC motor is arranged in the motor shell and can be used for household floor heating water circulation, solar water heating circulation, boiler water heating circulation, and various liquid circulation.

[0004] The inlet and outlet directions of the pump body of the existing circulating pump are fixed. After the control box is installed on the side wall or end of the circulating pump body, the orientation of the operation unit on the control box is fixed, which is easily constrained by the installation environment. When wall-mounted, if the water inlet is on the left end and the water outlet is on the right end, the control screen faces outward and can be easily operated. If the water inlet is on the right end and the water outlet is on the left end, the control screen faces outward, the operation unit faces the wall, and it is not easy to observe and operate, which is inconvenient to use and needs to be improved. SUMMARY

[0005] The technical scheme is provided to improve the problem that the installation of the circulating pump is constrained by the environment, resulting in inconvenient operation of the control box, and provides a control box turning structure and a circulating pump.

[0008] A clamping structure is arranged between the control box and the mounting seat. The clamping structure comprises clamping portions and clamping portions. When the control box rotates relative to the mounting seat, at least one clamping portion is fitted relative to the clamping portion to position the control box.

[0009] Through the technical scheme, when the circulating pump steering structure is normally used, the clamping portion is arranged on one of the control box and the mounting seat, and the clamping portion is arranged on the other one, a sufficient force is applied to drive the control box to rotate through the steering assembly, the clamping portion is deformed under the force and is separated from the clamping portion, with the rotation of the control box, at least one clamping portion is embedded with the clamping portion on the corresponding path in the rotation direction, until the control box is positioned at the required position, so that the control box is freely adjusted within a certain range, the control panel of the control box is turned to a suitable direction relative to the pump body through the rotation of the control box, thereby improving the flexibility of use and the operation is more convenient.

[0010] Preferably, the steering assembly comprises a mounting block arranged on the control box, a rotating piece fixed to the mounting block, and a rotating table portion arranged on the mounting seat.

[0011] The rotating piece is embedded with the rotating table portion, and the rotating piece can rotate axially relative to the rotating table portion.

[0012] The rotating table portion is provided with a mounting hole, and the rotating piece has a limiting ring at the lower end of the mounting hole, the limiting ring protrudes from the rotating piece, so that the limiting ring is limited to pass through the mounting hole.

[0014] Preferably, the rotating table portion is formed with a rotating groove corresponding to the internal region, the limiting ring rotates in the rotating groove, and the limiting ring has a limiting portion.

[0016] When the rotating piece rotates, the abutting surface one and the abutting surface two can abut against the opposite end surfaces of the limiting block, respectively, to limit the rotating piece from continuing to rotate.

[0017] Through the technical scheme, the rotating groove shape and size of the rotating table part matches the limiting ring of the rotating part, so that the limiting ring can rotate smoothly in the rotating groove, the two abutting surfaces abut against the limiting blocks protruding from the inner wall of the rotating groove when the rotating part rotates to a certain position, so as to limit continuous rotation, when the rotating part drives the limiting ring to rotate in the first direction, the first abutting surface will first contact one end surface of the limiting block to prevent the rotating part from continuously rotating in the direction, and similarly, when the control box rotates in the opposite direction, the second abutting surface will contact the other end surface of the limiting block to prevent rotation, thereby avoiding the problem of line entanglement due to excessive rotation, and facilitating maintenance and adjustment.

[0018] Preferably, the control box is provided with a mounting groove one, and the mounting block is mounted in the mounting groove one.
