Description

Technical Field

[0001] This utility model relates to the field of electric actuator technology, and in particular to a quick-connect structure for electric actuators. Background Technology

[0002] An electric actuator is a drive device that provides linear or rotary motion. It uses an electric motor as its power source and receives signals from the control system to achieve precise control of equipment such as valves and dampers. In application, the power output shaft of the electric actuator is typically connected to the power input shaft at the load end using bolt assemblies. This method is not convenient for disassembly and assembly, and if there is any error between the power output shaft and the power input shaft at the load end during connection, the installation position of the electric actuator or the position of the load needs to be adjusted, which is very cumbersome. To better solve this problem, we propose a quick-connect structure for electric actuators. Utility Model Content

A positioning screw is threaded onto the side of the connecting seat. A positioning groove is formed on the side of the power input shaft, and the positioning screw is inserted into the positioning groove.

[0006] Preferably, one end of the power output shaft is provided with a threaded hole, and a stud is threadedly connected to the threaded hole, with an end cap fixed to one end of the stud.

[0007] Preferably, a plurality of sliders are fixed on the inner wall of the connecting seat, and a plurality of sliding grooves are provided on the side of the power output shaft, and the sliders are slidably installed in the sliding grooves.

[0008] Preferably, the side of the connecting seat is provided with a groove, and the head of the positioning screw is located in the groove.

[0009] Preferably, a fixing seat is fixed on the connecting seat, a limiting plate is slidably sleeved inside the fixing seat, a limiting boss is fixed on the limiting plate, a spring is connected between the limiting boss and the fixing seat, a toggle block is fixed on the side of the limiting boss, and the limiting plate covers the groove.

[0010] Preferably, a rubber sleeve is fixedly fitted onto the inner wall of the positioning groove, and the positioning screw is located inside the rubber sleeve.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this utility model, the positioning screw can be inserted into the positioning groove through the threaded transmission between the positioning screw and the connecting seat, thereby quickly realizing the connection between the power output shaft and the power input shaft, thus realizing the transmission of power. The specific transmission process is as follows: the power output shaft drives the connecting seat to rotate synchronously, and the connecting seat drives the power input shaft to rotate synchronously through the positioning screw;

[0013] 2. In this utility model, the extension length of the connecting seat can be adjusted by sliding the slider in the groove, which is convenient to adjust according to the actual connection position of the power output shaft and the power input shaft. It can make up for the gap size error when connecting the power output shaft and the power input shaft. The connection is convenient, stable and quick. The end cap is provided to prevent the slider from sliding out.

[0014] 3. In this utility model, the groove helps to hide the positioning screw and avoid accidental contact.

[0018] 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.

[0019] Reference Figure 1 , Figure 2A quick-connect structure for an electric actuator includes a power output shaft 1 and a power input shaft 2. The power output shaft 1 is the output end of the electric actuator, and the power input shaft 2 is the load end of the electric actuator. A tubular connecting seat 8 is slidably sleeved on the power output shaft 1. A positioning screw 7 is threadedly sleeved on the side of the connecting seat 8. A positioning groove is formed on the side of the power input shaft 2, and the positioning screw 7 is inserted into the positioning groove. Through the threaded transmission between the positioning screw 7 and the connecting seat 8, the positioning screw 7 can be inserted into the positioning groove, thereby quickly connecting the power output shaft 1 and the power input shaft 2, thus realizing the transmission of power. The specific transmission process is as follows: the power output shaft 1 drives the connecting seat 8 to rotate synchronously, connecting... The connecting seat 8 drives the power input shaft 2 to rotate synchronously via the positioning screw 7. One end of the power output shaft 1 has a threaded hole, and a stud 5 is threaded into the threaded hole. One end of the stud 5 is fixed with an end cap 4. Several sliders 9 are fixed on the inner wall of the connecting seat 8. Several grooves 3 are opened on the side of the power output shaft 1. The sliders 9 are slidably installed in the grooves 3. By sliding the sliders 9 in the grooves 3, the extension length of the connecting seat 8 can be adjusted, which is convenient to adjust according to the actual connection position of the power output shaft 1 and the power input shaft 2. It can compensate for the gap dimension error when connecting the power output shaft 1 and the power input shaft 2. The connection is convenient, stable and quick. The end cap 4 is provided to prevent the sliders 9 from sliding out.

[0020] Reference Figure 2 The connecting seat 8 has a groove 15 on its side, and the head of the positioning screw 7 is located in the groove 15. A fixing seat 14 is fixed on the connecting seat 8. A limiting plate 6 is slidably sleeved in the fixing seat 14. A limiting boss 12 is fixed in the limiting plate 6. A spring 13 is connected between the limiting boss 12 and the fixing seat 14. A lever 11 is fixed on the side of the limiting boss 12. The limiting plate 6 covers the groove 15. A rubber sleeve 10 is fixedly sleeved on the inner wall of the positioning groove. The positioning screw 7 is located in the rubber sleeve 10. The groove 15 helps to hide the positioning screw 7 and avoid accidental contact. At the same time, the limiting plate 6 can prevent the positioning screw 7 from loosening and popping out, which would cause the connection to fail. The lever 11 can pull the limiting boss 12, and the limiting boss 12 drives the limiting plate 6 to move synchronously, which can push the limiting plate 6 to move, making it convenient to maintain the positioning screw 7. The rubber sleeve 10 buffers the positioning screw 7 during the start-up process to avoid rigid start-up.

[0021] Working principle: In use, the power output shaft 1 is the output end of the electric actuator, and the power input shaft 2 is the load end of the electric actuator. Through the threaded transmission between the positioning screw 7 and the connecting seat 8, the positioning screw 7 can be inserted into the positioning groove, thus quickly connecting the power output shaft 1 and the power input shaft 2, thereby realizing power transmission. The specific transmission process is as follows: the power output shaft 1 drives the connecting seat 8 to rotate synchronously, and the connecting seat 8 drives the power input shaft 2 to rotate synchronously via the positioning screw 7. The extension length of the connecting seat 8 can be adjusted by the sliding block 9 within the sliding groove 3, facilitating the adjustment according to the actual connection position of the power output shaft 1 and the power input shaft 2. Adjustments can compensate for dimensional errors in the spacing between the power output shaft 1 and the power input shaft 2, ensuring a convenient, stable, and quick connection. The end cap 4 prevents the slider 9 from slipping out. The groove 15 helps to conceal the positioning screw 7, preventing accidental contact. Simultaneously, the limiting plate 6 covers the screw, preventing it from loosening and slipping out, which could lead to connection failure. The limiting boss 12 can be pulled by the lever 11, causing the limiting plate 6 to move synchronously, thus facilitating maintenance of the positioning screw 7. The rubber sleeve 10 cushions the positioning screw 7 during startup, preventing rigid startup.
