Description

Technical Field

[0001] This utility model relates to the field of integrator technology, and in particular to an integrator with dual redundant outputs. Background Technology

[0002] A dual-redundant output integrator is an integrator with two independent output channels, which is widely used in key fields such as aerospace, high-end industrial automation control and precision power monitoring.

[0003] When using some integrators, the precise adjustment of the integrator sensitivity value mainly relies on the knob. However, most dual-redundant output integrators on the market lack an effective anti-accidental touch mechanism for the knob in terms of sensitivity adjustment. For example, when operators walk around the workshop or maintain equipment, they may accidentally touch the knob and change the sensitivity value, which will disrupt the stability of the production process. Furthermore, some existing anti-accidental touch designs simply increase the resistance of the knob rotation, but this not only fails to fundamentally eliminate accidental touch, but also increases the difficulty of operation for operators when adjusting the sensitivity value. Operators need to exert more force to turn the knob, which can easily lead to fatigue during long-term operation, resulting in decreased adjustment accuracy and reduced work efficiency. Moreover, in the face of unexpected strong impacts or pressure, this type of design is difficult to effectively prevent the knob from being accidentally turned, and cannot guarantee the accuracy and stability of the integrator sensitivity adjustment. Utility Model Content

[0004] The purpose of this invention is to provide an integrator with dual redundant outputs, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A dual-redundant output integrator includes a protective housing. Multiple external power ports are fixedly installed on the front side of the protective housing. Connection ports are fixedly installed on the middle of both sides of the protective housing. The external power ports and connection ports are electrically connected to a main control board inside the protective housing via connecting cables. A top cover is fixedly installed on the protective housing. A sensitivity adjustment knob is fixedly installed in the middle of the top cover. The sensitivity adjustment knob includes a knob base, on which a knob cap is movably installed. Multiple embedding slots are formed on the outer side of the knob cap. A push button is fixedly connected to the top of each embedding slot. A mounting slot is formed inside the push button, and two semi-circular push rods are movably installed within the mounting slot.

[0007] As a further preferred embodiment of this utility model, a fixing ring is fixedly installed on the knob seat, a limiting ring is fixedly installed on the outer side of the fixing ring, a plurality of limiting grooves are opened on the inner side of the fixing ring, and the knob seat located on the inner side of the fixing ring is also provided with a shaft hole. The knob seat is fixedly installed on the top cover. The knob seat is installed on the top cover, and the fixing ring on the knob seat can provide conditions for the rotation installation of the knob cap, while the opening of the limiting groove can provide conditions for the limiting of the knob cap.

[0008] As a further preferred embodiment of this utility model, a spline groove is provided at the top of the mounting groove, and a mounting through groove is provided on the inner side of the mounting groove near the embedding groove. One end of the mounting through groove is connected to the mounting groove, and the other end is connected to the embedding groove. The knob cap is rotatably mounted on the fixing ring and the limiting ring through the rotating groove on the inner side of the mounting groove. After the knob cap is rotatably mounted on the knob seat, the rotation adjustment of the spline shaft can be achieved by the insertion of the spline groove and the spline shaft, thereby adjusting the sensitivity value of the integrator.

[0009] As a further preferred embodiment of this utility model, limit blocks are fixedly installed in the middle of the two semicircular push rods respectively, and a top plate is fixedly installed on the semicircular push rod near the limit block. An insert plate is fixedly installed on the top plate, and the combination structure of the top plate and the insert plate is an inverted L shape.

[0010] As a further preferred embodiment of this utility model, both ends of the two semicircular push rods are connected to connecting shafts. The connecting shaft between the two semicircular push rods is also fitted with a compression spring. One end of the insert plate passes through the corresponding mounting slot and extends into the embedding slot. One side of the limiting block is inserted into the corresponding limiting slot. With the cooperation of the two sets of connecting shafts and compression springs, the limiting blocks on one side of the two semicircular push rods can be respectively engaged in the corresponding limiting slots. This can limit the rotation of the knob cap in conjunction with the top plate and the insert plate. That is, when unlocking the knob cap rotation limit, it is necessary to simultaneously operate the two buttons to displace the two semicircular push rods, thereby achieving the function of preventing accidental activation of the knob cap.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] In this invention, a fixing ring and a limiting ring are provided on the knob base, and multiple limiting grooves are opened on the inner side of the limiting ring. This allows the knob cap to be rotated and installed on the fixing ring and the limiting ring. The rotation of the knob cap is limited by the two sets of semi-circular push rods, connecting shaft, compression spring, top plate, and insert plate provided on the inner side, so that the knob cap has an anti-accidental touch function. When unlocking the knob cap rotation limit, two embedded grooves need to be pressed simultaneously to control the two semi-circular push rods to move synchronously, so that the limiting block on one side of the semi-circular push rod disengages from the corresponding limiting groove, thereby improving the anti-accidental touch effect of the knob cap.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figures 1-4 As shown, the present invention provides a dual-redundant output integrator, including a protective shell 1. Multiple external power ports 2 are fixedly installed on the front side of the protective shell 1. Connection ports 3 are fixedly installed on the middle of both sides of the protective shell 1. The external power ports 2 and connection ports 3 are electrically connected to the main control board inside the protective shell 1 through connecting wires. A top cover 4 is fixedly installed on the protective shell 1. A sensitivity adjustment knob 5 is fixedly installed on the middle of the top cover 4. The sensitivity adjustment knob 5 includes a knob base 6. A knob cap 7 is movably installed on the knob base 6. Multiple embedding slots 8 are opened on the outer side of the knob cap 7. A push button 9 is fixedly connected to the top of the embedding slot 8. A mounting slot 14 is opened in the push button 9. Two semi-circular push rods 10 are movably installed in the mounting slot 14.

[0020] like Figures 2-4As shown, a fixing ring 11 is fixedly installed on the knob seat 6, and a limiting ring 12 is fixedly installed on the outer side of the fixing ring 11. Multiple limiting grooves 13 are opened on the inner side of the fixing ring 11, and the knob seat 6 located inside the fixing ring 11 also has a shaft hole. The knob seat 6 is fixedly installed on the top cover 4. The fixing ring 11 on the knob seat 6 provides conditions for the rotational installation of the knob cap 7, while the limiting grooves 13 provide conditions for the limiting of the knob cap 7. The mounting groove 1... A spline groove 15 is provided at the top of the mounting groove 14. A mounting through groove 16 is provided on the inner side of the mounting groove 14 near the embedded groove 8. One end of the mounting through groove 16 is connected to the mounting groove 14, and the other end is connected to the embedded groove 8. The knob cap 7 is rotatably mounted on the fixing ring 11 and the limiting ring 12 through the rotating groove on the inner side of the mounting groove 14. After the knob cap 7 is rotatably mounted on the knob seat 6, the rotation of the spline shaft 22 can be adjusted by inserting the spline groove 15 into the spline shaft 22, thereby adjusting the sensitivity value of the integrator. Limiting blocks 21 are fixedly installed in the middle of the two semicircular push rods 10. A top plate 19 is fixedly installed on the semicircular push rod 10 near the limiting block 21. An insert plate 20 is fixedly installed on the top plate 19. The combination structure of the top plate 19 and the insert plate 20 is inverted L-shaped. A connecting shaft 17 is inserted and connected to both ends of the two semicircular push rods 10. A compression spring 18 is also fitted on the connecting shaft 17 located between the two semicircular push rods 10. One end of the insert plate 20 passes through the corresponding mounting slot 16 and extends into the embedded slot 8. One side of the limiting block 21 is inserted into the corresponding limiting groove 13. With the help of two sets of connecting shafts 17 and compression springs 18, the two semi-circular push rods 10 can make the limiting blocks 21 on one side of the two semi-circular push rods 10 respectively engage in the corresponding limiting grooves 13. This can work with the top plate 19 and the insert plate 20 to limit the rotation of the knob cap 7. That is, when unlocking the knob cap 7 to rotate to the limit, the two pressing buttons 9 need to be operated simultaneously to displace the two semi-circular push rods 10, thereby achieving the function of preventing accidental touch of the knob cap 7.

[0021] It should be noted that this utility model is an integrator with dual redundant output. When it is necessary to control the rotation of the spline shaft 22 by rotating the knob cap 7, thereby adjusting the integrator sensitivity value from 1A to over 100KA, simply pinch the two pressing buttons 9 with two fingers of one hand and press them into the corresponding embedded slots 8. This will cause the upper ends of the two pressing buttons 9 to deform at the connection points with the embedded slots 8, thereby causing the lower ends of the two embedded slots 8 to press and move the corresponding insert plates 20 to one side. Then, the insert plates 20 drive the semi-circular push rods 10 to one side through the top plate 19. As a result, the two semi-circular push rods 10 move synchronously relative to each other and pass through the shaft holes at both ends of their respective connecting shafts 17. Furthermore, the two ends of the two semi-circular push rods 10 also respectively connect the corresponding connecting shafts 17. When the compression spring 18 on shaft 17 is compressed, the two semi-circular push rods 10 will be horizontally displaced, and the limiting block 21 on one side will disengage from the corresponding limiting groove 13. At this time, the knob cap 7 can be rotated, which will cause the spline shaft 22 to rotate to cooperate with the electrical components on the main control board inside the protective shell 1 to adjust the sensitivity. After the adjustment is completed, the two fingers are released, which will reset the two buttons 9. When the insert plate 20 is no longer under the pressure of the button 9, the two compression springs 18 will extend and rebound, pushing the two semi-circular push rods 10 to one side respectively, so that the limiting block 21 on one side of the two semi-circular push rods 10 will be re-engaged into the corresponding limiting groove 13. This will cooperate with the semi-circular push rods 10, the top plate 19, and the insert plate 20 to limit the axial movement of the knob cap 7.
