Abstract
Description
Technical Field
[0001] This invention belongs to the field of transformer technology, and particularly relates to a toroidal transformer. Background Technology
[0002] With the rapid development of society and the economy, toroidal transformers have become a very common type of transformer in people's daily lives. Toroidal transformers are a major type of electronic transformer and are widely used in household appliances and other technically demanding electronic equipment. Their main uses are as power transformers and isolation transformers. Toroidal transformers have a complete series available abroad and are widely used in computers, medical equipment, telecommunications, instruments, and lighting, among other fields.
[0003] However, in the existing technology, the installation of toroidal transformers is mostly not very effective in fixing them. If vibration or shaking occurs, the stability of the toroidal transformer cannot be guaranteed, which can easily affect its stable operation. Although some equipment can fix the toroidal transformer stably, disassembly is very inconvenient and not conducive to subsequent maintenance. Summary of the Invention
[0004] In view of this, the technical problem to be solved by the present invention is to provide a toroidal transformer that is easy to disassemble while ensuring stable fixation.
[0005] A toroidal transformer includes a fixed base, a fixed ring placed on the fixed base, a transformer body fixedly connected to the fixed ring, the lower side of the transformer body being able to contact the fixed base, an upper plate being able to be inserted into the fixed base, a mating block being slidably connected to the upper plate, a first compression spring being fixedly connected between the mating block and the upper plate, the lower side of the mating block being an inclined surface with a gradually increasing slope from left to right, a transmission arc surface being provided on the fixed base, the lower side of the mating block being able to contact the transmission arc surface, an arc-shaped mating groove being provided on the fixed base, the mating block being able to be inserted into the arc-shaped mating groove, and the upper plate being able to contact the upper side of the transformer body.
[0006] It also includes a rectangular protrusion fixed to the fixing ring, and a rectangular groove is provided on the fixing seat so that the rectangular protrusion can be inserted into the rectangular groove.
[0007] It also includes two auxiliary pressure parts connected to the fixed base. The same fixed round rod can be inserted into the two auxiliary pressure parts. Two round holes are opened on the upper plate, and the fixed round rod can be inserted into the two round holes.
[0008] Both auxiliary pressure parts are slidably connected to the fixed base, and a second compression spring is fixed between each auxiliary pressure part and the fixed base. Both auxiliary pressure parts can contact the upper plate. Attached Figure Description

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 9 As shown:
[0020] A toroidal transformer includes a fixed base 101, a fixed ring 201 placed on the fixed base 101, a transformer body 204 fixedly connected to the fixed ring 201, the lower side of the transformer body 204 being able to contact the fixed base 101, an upper plate 401 being able to be inserted into the fixed base 101, a mating block 501 slidably connected to the upper plate 401, a first compression spring being fixedly connected between the mating block 501 and the upper plate 401, the lower side of the mating block 501 being a slope that gradually increases from left to right, a transmission arc surface 103 provided on the fixed base 101, the lower side of the mating block 501 being able to contact the transmission arc surface 103, an arc-shaped mating groove 102 provided on the fixed base 101, the mating block 501 being able to be inserted into the arc-shaped mating groove 102, the upper plate 401 being able to contact the upper side of the transformer body 204, and the mating block 501 being able to move left and right along the upper plate 401.
[0021] When using this equipment, fix the mounting base 101 at the location where the transformer will be placed, and then place the fixing ring 201 on the mounting base 101, thereby forming a connection between the fixing ring 201 and the mounting base 101. Figure 1 As shown in the diagram, the upper plate 401 is then gradually inserted into the fixing base 101, thereby forming a connection between the upper plate 401 and the fixing base 101. Figure 9 As shown, during the insertion of the upper plate 401, the mating block 501 gradually contacts the transmission arc surface 103. Since the lower side of the mating block 501 is inclined and the transmission arc surface 103 can push the mating block 501, the mating block 501 gradually overcomes the elastic force of the first compression spring and retracts into the upper plate 401. When the mating block 501 continues to move downwards and gradually moves to the position coinciding with the arc-shaped mating groove 102, the mating block 501 will be automatically inserted into the arc-shaped mating groove 102 by the elastic force of the first compression spring. At this time, the upper plate 401 will be exactly positioned above the transformer body 204. The engagement of the slot 102 and the mating block 501 prevents the upper plate 401 from being pulled upward from the fixed seat 101. This allows the upper plate 401 and the fixed seat 101 to work together to securely clamp and fix the transformer body 204, thus preventing the transformer body 204 from being affected by vibration during operation and thus affecting its working stability. At the same time, the upper plate 401 and the fixed seat 101 can work together to squeeze and fix the coils on the transformer body 204, thereby preventing the coils from loosening after long-term use and further ensuring working stability.
[0022] When it is necessary to remove the transformer body 204 from its fixed position for maintenance, the upper plate 401 can be rotated clockwise on the fixed base 101. Figure 1 It is known that the space inside the arc-shaped mating groove 102 gradually decreases in the clockwise direction. As the upper plate 401 rotates, the space inside the arc-shaped mating groove 102 gradually presses the mating block 501 to slide on the upper plate 401, causing the mating block 501 to gradually retract into the upper plate 401 until the mating block 501 is completely removed from the arc-shaped mating groove 102. That is, the mating block 501 is in the state of being completely retracted into the upper plate 401, and the restrictive effect of the arc-shaped mating groove 102 on the mating block 501 can be removed. At this time, the upper plate 401 can be operated to slide upward and pull the upper plate 401 out of the fixed seat 101, thereby removing the fixing effect on the transformer body 204. The transformer body 204 can then be quickly disassembled for maintenance. Thus, this equipment can provide a simple disassembly method for the transformer body 204 while ensuring stable fixation.
[0023] like Figure 3 , Figure 6 and Figure 9 As shown:
[0024] It also includes a rectangular protrusion 205 fixed to the fixing ring 201, and a rectangular groove 105 is provided on the fixing seat 101, so that the rectangular protrusion 205 can be inserted into the rectangular groove 105.
[0025] When placing the fixing ring 201 on the fixing seat 101, the rectangular protrusion 205 is inserted into the rectangular groove 105, so that the fixing ring 201 and the fixing seat 101 are placed together in a non-rotatable position. This ensures that when the upper plate 401 is rotated and the fixing effect on the fixing ring 201 is removed, the fixing ring 201 will not rotate synchronously with the upper plate 401, thus ensuring the normal operation of rotating the upper plate 401.
[0026] like Figure 3 , Figure 4 and Figure 9 As shown:
[0027] It also includes two auxiliary pressing parts 301 connected to the fixed base 101. The same fixed round rod 302 can be inserted into the two auxiliary pressing parts 301. Two round holes are opened on the upper plate 401, and the fixed round rod 302 can be inserted into the two round holes.
[0028] During the installation of this equipment, after placing the upper plate 401 on the fixing ring 201 and inserting the mating block 501 into the arc-shaped mating groove 102, the fixing rod 302 can be passed through the two auxiliary pressing parts 301 and the round holes on the two fixing rods 302, thereby forming the fixing rod 302. Figure 9 As shown in the figure, the upper plate 401 is fixed by the fixed round rod 302, so that the upper plate 401 cannot be rotated at will, thus ensuring the stable fixing effect of the upper plate 401 and the fixed seat 101 on the transformer body 204 for a long time. When it is necessary to rotate the upper plate 401 to disassemble the transformer body 204, the fixed round rod 302 can be pulled out to carry out the subsequent disassembly work, thus further ensuring the convenience of disassembly work.
[0029] like Figure 3 , Figure 4 and Figure 9 As shown:
[0030] Both auxiliary pressure parts 301 are slidably connected to the fixed base 101, and a second pressure spring is fixed between each auxiliary pressure part 301 and the fixed base 101. Both auxiliary pressure parts 301 can contact the upper plate 401.
[0031] After the installation of the upper plate 401 is completed, the two auxiliary pressure parts 301 are respectively subjected to the elastic force of the two second compression springs and thus tightly press against both sides of the upper plate 401, thereby further increasing the fixing effect of the upper plate 401. This ensures that even if wear occurs between the fixing rod 302 and the two round holes on the upper plate 401 due to increased use time, resulting in the inability to guarantee the fixing effect of the fixing rod 302 on the upper plate 401, or if the fixing rod 302 breaks during use, or if the operator forgets to insert the fixing rod 302, the upper plate 401 can still be fixed to a certain extent by the increased clamping force of the two auxiliary pressure parts 301. This ensures that the upper plate 401 still has a certain characteristic of maintaining its own stability, thereby guaranteeing a stable fixing effect.
[0032] like Figure 2 and Figure 4 As shown:
[0033] It also includes a rubber strip 402 fixed to the lower side of the upper plate 401, and an annular groove 202 is provided on the fixing ring 201.
[0034] When installing the upper plate 401, the rubber strip 402 can be inserted into the annular groove 202, so that the rubber strip 402 can provide a larger rotational friction force for the upper plate 401, thereby further increasing the external force required to rotate the upper plate 401, and further enabling the upper plate 401 to be stably inserted into the fixing seat 101, ensuring a stable fixing effect.
[0035] like Figure 1 , Figure 2 , Figure 4 and Figure 7 As shown:
[0036] It also includes a vertical roller 403 that is slidably connected to the upper plate 401. A limiting groove 203 is provided on the fixing ring 201, and a third compression spring is fixed between the vertical roller 403 and the upper plate 401.
[0037] When placing the upper plate 401, the vertical roller 403 on the upper plate 401 slides to the right against the elastic force of the third compression spring. This causes the vertical roller 403 to be inserted into the shorter arc-shaped section of the limiting groove 203 after the upper plate 401 is placed. Consequently, when disassembling the transformer body 204, the upper plate 401 cannot be rotated clockwise directly; the operator must first rotate the upper plate 401 counterclockwise by a certain angle, so that the vertical roller 403 follows the upper plate 401 and moves synchronously within the shorter arc-shaped section of the limiting groove 203. The vertical roller 403 moves within the arc shape on the side until it reaches the intersection of the longer and shorter arc shapes on the limiting groove 203. At this point, the elastic force of the third compression spring will cause the vertical roller 403 to press against the front of the limiting groove 203. Then, the upper plate 401 is rotated clockwise, so that the limiting groove 203 gradually enters the area of the longer arc shape on the limiting groove 203, thereby removing the restriction on the rotation direction of the upper plate 401 and providing sufficient stroke for the clockwise rotation of the upper plate 401, so that the subsequent disassembly work can be carried out normally.
[0038] This structure further ensures the stable fixation of the transformer body 204, further reducing the possibility of accidental removal of the upper plate 401, and enabling only personnel who know how to remove the fixation to quickly disassemble the transformer body 204, thus providing convenience for actual use.
[0039] like Figure 4 and Figure 9 As shown:
[0040] The vertical roller 403 penetrates the upper plate 401.
[0041] The through-hole design of the vertical roller 403 allows the operator to manually push the vertical roller 403 from the top of the upper plate 401 during the installation of the upper plate 401. This pushes the vertical roller 403 against the elastic force of the third compression spring to a position where it can be inserted into the arc shape on the shorter side, thus ensuring the smooth progress of subsequent installation work.
[0042] like Figure 1 , Figure 4 and Figure 9 As shown:
[0043] Both the mounting base 101 and the upper plate 401 are made of stainless steel.
[0044] The stainless steel material ensures that the surface of the fixed base 101 and the upper plate 401 will not rust due to the continuous use over time, thus not affecting the service life of the equipment.
[0045] like Figure 9 As shown:
[0046] The auxiliary pressure part 301 is wrapped with a rubber layer.
[0047] The rubber layer can further increase the external force required to rotate the upper plate 401, thereby further improving the auxiliary fixing effect of the upper plate 401.
[0048] like Figure 1 As shown:
[0049] The fixed base 101 has multiple threaded holes.
[0050] The mounting base 101 can be fixed by screwing bolts into multiple threaded holes, thereby fixing the mounting base 101 at the position of the transformer to be installed, thus facilitating subsequent installation work.
