Description

Technical Field

[0001] This utility model relates to the field of handwheels, specifically a handwheel assembly. Background Technology

[0002] Top-mounted handwheels are commonly used actuators for regulating valves. Under current technology, the handle of a top-mounted handwheel is a single integrated unit, which is very inconvenient for transportation and therefore needs to be improved. Utility Model Content

[0003] The purpose of this utility model is to provide a handwheel assembly to solve the problems mentioned in the background art, which has the advantages of convenient assembly and transportation.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a handwheel assembly, including a turntable, a concave plate integrally connected to one side of the turntable, a handle rotatably connected to the concave plate, a circular plate integrally connected to the middle of the turntable, a circular groove passing through the circular plate, a rotating shaft installed inside the circular groove, a first pin groove communicating with the circular groove and located on one side of the circular groove, a second pin groove on one side of the rotating shaft, and a pin inserted into both the first and second pin grooves passing through the turntable.

[0005] By adopting the above technical solution, during assembly, the rotating shaft is placed on one side of the turntable, and then the pins are inserted into the first pin slot and the second pin slot in sequence. At this time, under the action of the pins, the rotating shaft will rotate with the turntable. When the turntable needs to rotate, pull the handle until the handle is set perpendicular to the turntable. Then, use the handle to drive the turntable to rotate, thereby driving the pin to rotate and thus driving the rotating shaft to rotate.

[0006] As a further embodiment of this utility model: the rotating shaft is sleeved with a square frame, the outer side of the rotating shaft is sleeved with a sleeve shaft, the rotating shaft is provided with a slot for one end of the square frame to be inserted, and the inner side of the sleeve shaft is provided with a square groove for accommodating the square frame.

[0007] By adopting the above technical solution, the square frame is placed in the square groove, and one end of the square frame is inserted into the groove in the rotating shaft. The rotation of the rotating shaft will drive the square frame to rotate, which in turn drives the sleeve shaft to rotate, thus playing the role of rotation transmission.

[0008] As a further improvement of this utility model, a sealing ring is provided on the inner side of the sleeve shaft and fitted onto the outer side of the rotating shaft.

[0009] By adopting the above technical solution, the sealing ring increases the sealing performance between the sleeve and the rotating shaft.

[0010] As a further embodiment of this utility model: a circular hole is provided in the middle of the rotating shaft, a pin is engaged with the rotating shaft through the circular hole, an indicator plate is provided on the end face of the rotating shaft, and the indicator plate is fixedly connected to the rotating shaft through the pin.

[0011] By adopting the above technical solution, the indicator disc is placed on the end face of the rotating shaft, and then the pin is engaged with the rotating shaft through the round hole to install the indicator disc.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] During assembly, place the shaft on one side of the turntable, and then insert the pins into the first and second pin slots in sequence. At this time, the shaft will rotate with the turntable under the action of the pins. When the turntable needs to rotate, pull the handle until the handle is perpendicular to the turntable. Then use the handle to drive the turntable to rotate, thereby driving the pin to rotate and in turn driving the shaft to rotate. Attached Figure Description
