Description

Technical Field

[0001] The present invention relates to a connection structure of a controller, and particularly to a connection structure of a voltage regulator control box. Background Art

[0002] Intelligent voltage regulators are all equipped with control boxes on their bodies, and the control boxes are generally fixed on one side of the voltage regulator. Since small voltage regulators are installed at a relatively high position, often on utility poles, and the fixed control boxes have many inconveniences in use, a connection structure that can move the control box is needed to meet the needs of transportation, installation, operation, and maintenance. Summary of the Invention

[0003] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a connection structure of a voltage regulator control box, so that the voltage regulator and the control box can be conveniently and quickly switched to different connection states.

[0004] To solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A connection structure of a voltage regulator control box includes that the voltage regulator body is connected to the control box through a connection structure. The connection structure is that a lower support angle steel and an upper support angle steel are hinged through a rotating shaft with a longitudinally arranged installation groove plate. The rotating shaft is arranged on one side of the installation groove plate, and the upper support angle steel is provided with a locking device, which is connected to a limiting device arranged at the upper end of the installation groove plate through an adjusting device.

[0006] The locking device includes a first pin shaft fixedly arranged on the upper support angle steel, and a clamping groove with an opening structure is arranged at one end far from the rotating shaft.

[0007] The adjusting device includes a pull plate provided with a first pin hole and a second pin hole. The pull plate is hinged to the upper support angle steel by sleeving the first pin shaft through the first pin hole or the second pin hole, and a second pin shaft is fixedly arranged at the corresponding end of the pull plate and the clamping groove.

[0008] The diameters of the pin heads of the first pin shaft and the second pin shaft are larger than the diameters of the pin shafts.

[0009] The diameters of the first pin hole and the second pin hole are greater than or equal to the diameter of the pin head of the first pin shaft, and the opening width of the clamping groove is greater than or equal to the diameter of the first pin shaft.

[0010] A communicating slot hole is arranged between the first pin hole and the second pin hole, and the width of the slot hole is smaller than the diameters of the first pin hole and the second pin hole, and greater than or equal to the diameter of the pin shaft of the first pin shaft.

[0011] The limiting device includes a moving hole arranged at the upper end of the installation groove plate, and a limiting hole is arranged at one end of the moving hole close to the rotating shaft.

[0012] The width of the moving hole is smaller than the diameter of the pin head of the second pin shaft, and greater than or equal to the diameter of the pin shaft of the second pin shaft.

[0013] The diameter of the limiting hole is greater than or equal to the diameter of the pin head of the second pin shaft.

[0014] Bolting holes are provided through corresponding positions at the lower end of the mounting groove plate and the lower support angle steel.

[0015] The beneficial effects of the present invention: By adjusting the position of the pull rod, with the cooperation of the pin shaft, pin hole, card slot, slot hole and moving hole, the functions of locking and limiting are realized. The operation is simple and convenient to use, and it can meet the needs of both transportation, installation, operation and maintenance. Description of the Drawings

Detailed Embodiments Embodiment 1

[0022] As Figure 1 shown, the lower support angle steel 2 and the upper support angle steel 3 are welded to the pressure regulator body 1. The rotating shaft 8 provided on one side of the mounting groove plate 7 is longitudinally arranged between the lower support angle steel 2 and the upper support angle steel 3 to form a hinge. The mounting groove plate 7 rotates around the rotating shaft 8, and the control box 9 is installed on the mounting groove plate 7. Bolting holes are provided through corresponding positions at the lower end of the mounting groove plate 7 and the lower support angle steel 2. During transportation, they are fixedly connected with bolts 10 and nuts 11, and the bolts 10 and nuts 11 are removed after the pressure regulator is installed in place. Embodiment 2

[0023] As Figure 3 , Figure 4As shown, when the control box is transported and installed, when the second pin hole 13 on the pull plate 5 is inserted into the pin head of the first pin shaft 4, the second pin shaft 6 fixed by the pull plate 5 is stuck in the slot 14, the mounting slot plate 7 is locked, and the mounting slot plate 7 and the control box 9 installed thereon cannot rotate; when unlocking, lift and move the pull plate 5, so that the pin shaft body of the first pin shaft 4 moves through the slot hole into the first pin hole 12, lower the pull plate 5, so that the first pin hole 12 is inserted into the fixed section of the first pin shaft 4, the second pin shaft 6 fixed by the pull plate 5 exits the slot 14, the mounting slot plate 7 is unlocked, and the mounting slot plate 7 and the control box 9 installed thereon can rotate. Example 3

[0024] like Figure 5 As shown, when the control box is operated or maintained, the mounting slot plate 7 and the control box 9 mounted thereon rotate around the rotating shaft 8, and the pull plate 5 rotates with the first pin shaft 4 as the axis, while the pin shaft body of the second pin shaft 6 fixed to the pull plate 5 slides in the movable hole 15; when the control box 9 reaches the operation or maintenance position, the pin shaft head of the second pin shaft 6 falls into the limiting hole 16, which plays a role in limiting the rotation of the control box 9; multiple limiting holes 16 can be processed according to the needs of the operation or maintenance position; when the second pin shaft 6 is lifted so that its pin shaft head is out of the limiting hole 16, the control box 9 can rotate.

[0025] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
