Description

Technical Field

[0001] The utility model relates to the technical field of mutual inductors, in particular to a fixing base of a mutual inductor. Background Art

[0002] Instrument transformers are widely used in power systems, mainly for accurate measurement and conversion of voltage and current, as well as to provide support for the monitoring and protection functions of the system. In order to ensure the stability and reliability of the instrument transformer, the design and installation of the fixed base are particularly important. This base not only provides physical support for the instrument transformer to ensure its stability during operation, but also plays a certain role in vibration reduction and noise reduction.

[0003] At present, the base of the transformer is generally fixed by screw connection. The advantage of this method is that it can ensure the fixation and safety of the transformer under various environmental conditions. However, the screw connection method also has some inconveniences. First, the installation process is relatively cumbersome and requires precise operation to ensure the firmness and reliability of the connection. In addition, when the transformer needs to be replaced or maintained, the removal of the screw connection is also inconvenient, which may prolong the maintenance time and increase the maintenance cost.

[0004] In addition, the screw connection may have thread slippage problems during long-term use, which not only affects the fixing stability of the transformer, but may also cause additional troubles for maintenance personnel during installation or replacement.

[0005] Therefore, those skilled in the art have proposed a fixing base for a mutual inductor. Utility Model Content

[0012] The push rod is fixedly connected to one side of the corresponding sliding plate and one end thereof extends to the outside of the base, the pressing plate is fixedly connected to the outside of the corresponding push rod, and the locking rod is fixedly connected to one side of the sliding plate.

[0013] Through the above technical means, by pressing the pressing plate, the pressing plate is squeezed and then drives the sliding plate to move through the push rod.

[0014] As a preferred embodiment, a sliding groove is opened on one side of the base, an adjustment groove is opened inside the connecting plate, one end of the locking rod passes through the sliding groove and extends to the outside of the adjustment groove, and the locking rod is set to an L-shaped structure.

[0015] Through the above technical means, when the sliding plate moves, it will drive the locking rod to move, so that the two locking rods are close to each other, and then the locking rods can be separated from the adjustment groove and the sliding groove.

[0016] As a preferred embodiment, the clamping mechanism further includes a fixing groove, a sliding block and an inserting rod;

[0017] The fixing grooves are equidistantly arranged above the base and located outside the transformer body, and the sliding blocks are respectively slidably connected inside the corresponding fixing grooves.

[0018] Through the above technical means, the slider is movably connected in the fixed groove, and different types of connecting plates can be adapted by adjusting the position of the slider.

[0019] As a preferred implementation, the slider and the locking rod are both provided with through holes, and the insertion rod is slidably connected between two corresponding through holes.

[0020] Through the above technical means, two insertion rods are inserted into the through holes, so that the slider and the locking rod can be limited, so that the slider cannot be separated from the fixing groove, and the locking rod cannot move, thereby achieving the limiting effect.

[0021] As a preferred embodiment, the sliding block is configured as a cross structure, and a sealing plate is provided at one end thereof.

[0022] Through the above technical means and the above settings, the slider can be limited to prevent it from slipping.

[0023] Compared with the prior art, the advantages and positive effects of the utility model are:

[0024] The utility model can quickly connect the base and the connecting plate by setting a clamping mechanism. After the base is limited, the entire base is fixed by an insertion rod, so that the base cannot shake and the slider cannot fall off. The advantage of this arrangement is that it can avoid the tedious steps of screw connection and avoid the problem of slipping threads and misaligned holes. It is not only easy to install, but also can be quickly disassembled, which is more convenient in actual use. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The clamping mechanism includes a slot body 4, a sliding plate 5, a damper 6 and a spring 7;

[0035] The grooves 4 are symmetrically arranged inside the base 2, the sliding plates 5 are slidably connected inside the corresponding grooves 4, the dampers 6 are connected between the corresponding sliding plates 5 and the grooves 4, and the springs 7 are sleeved on the outside of the dampers 6 and located between the sliding plates 5 and the grooves 4;

[0036] In summary, when the sliding plate 5 moves, it will drive the damper 6 to be compressed. During the compression process, the damper 6 will also squeeze the spring 7, and the spring 7 provides rebound power for the sliding plate 5.

[0037] like Figure 1-Figure 4 As shown, the clamping mechanism further includes a push rod 8, a push plate 9 and a locking rod 10;

[0038] The push rod 8 is fixedly connected to one side of the corresponding sliding plate 5 and one end thereof extends to the outside of the base 2, the pressing plate 9 is fixedly connected to the outside of the corresponding push rod 8, and the locking rod 10 is fixedly connected to one side of the sliding plate 5;

[0039] In summary: by pressing the pressing plate 9 , the pressing plate 9 is squeezed and the sliding plate 5 is driven to move through the push rod 8 .

[0040] like Figure 1-Figure 4 As shown, a sliding groove 11 is provided on one side of the base 2, an adjusting groove 12 is provided inside the connecting plate 1, one end of the locking rod 10 passes through the sliding groove 11 and extends to the outside of the adjusting groove 12, and the locking rod 10 is set to an L-shaped structure;

[0041] In summary, when the sliding plate 5 moves, it will drive the locking rods 10 to move, so that the two locking rods 10 are close to each other, and then the locking rods 10 can be separated from the adjusting groove 12 and the sliding groove 11.

[0042] like Figure 1-Figure 4 As shown, the clamping mechanism further includes a fixing groove 13, a slider 14 and an insertion rod 15;

[0043] The fixing grooves 13 are equidistantly arranged above the base 2 and located outside the transformer body 3, and the sliders 14 are slidably connected to the inside of the corresponding fixing grooves 13;

[0044] In summary: the slider 14 is movably connected in the fixing groove 13 , and different types of connecting plates 1 can be adapted by adjusting the position of the slider 14 .

At the same time, when installing, the pressing plate 9 is released, and the locking rod 10 is reset under the elastic force of the spring 7, so that the base 2 is limited by the locking rod 10. After that, the two plug rods 15 are inserted into the through holes, so that the slider 14 and the locking rod 10 can be limited, so that the slider 14 cannot be separated from the fixing groove 13, and the locking rod 10 cannot move. The limiting effect can be achieved, so that the entire device is fixed.
