Description

Technical Field

[0001] This application relates to the field of transformer technology, and more particularly to a control transformer structure. Background Technology

[0002] A control transformer is a small, dry-type transformer commonly used as a power source for local lighting, signal lights, or indicator lights, and as a power source for control circuits in electrical equipment. The control transformer terminal cover is the part of the transformer used to connect wires. Its main component is a metal plate encased in insulating plastic, with holes at both ends for inserting wires, and it is secured or released with screws. The terminal cover design allows for convenient and quick connection of wires to electrical equipment, while ensuring reliable contact and sufficient current carrying capacity.

[0003] In the existing technology, the terminal covers of transformers are directly exposed to the outside of the equipment. During the transportation of transformers, the terminal covers lack effective protection, making them susceptible to deformation and cracking due to collisions during loading and unloading. Therefore, an improvement is now made to the structure of a control transformer. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a control transformer structure that overcomes these deficiencies. The aim is to solve the problem that the terminal covers of existing transformers are directly exposed to the outside of the equipment, and that the terminal covers are easily deformed and cracked due to collisions during loading and unloading.

[0005] To achieve the above objectives, this application provides the following technical solution: a control transformer structure, including a mounting frame, a transformer body fixedly mounted inside the mounting frame, a terminal cover electrically connected to the transformer body fixedly mounted on the upper surface of the mounting frame, a protective cover hinged to one side of the upper surface of the mounting frame, a connecting block fixedly connected to the outer wall of the protective cover away from the hinge, a fixed seat fixedly mounted on the other side of the upper surface of the mounting frame, a placement groove for inserting the connecting block opened on the top of the fixed seat, a sliding groove opened inside the fixed seat, sliding blocks symmetrically arranged on both sides of the placement groove inside the sliding groove, a return spring fixedly connected between the two sliding blocks, a fixed rod fixedly connected to the outer wall of the two sliding blocks near the connecting block, and the other end of the fixed rod slidably inserted into the interior of the connecting block, and an adjusting block fixedly connected to the side wall of the sliding block.

[0006] By adopting the above technical solution, the protective cover installed by the hinge can be opened and closed to cover the terminal cover, forming a physical barrier to directly avoid collision damage during transportation. After the connecting block is inserted into the placement slot of the fixing seat, the sliding blocks on both sides push the fixing rod into the interior of the connecting block under the action of the return spring, realizing automatic locking. The displacement of the sliding block can be manually controlled by the adjusting block to adjust the position of the fixing rod, so that the fixing rod can be pulled out from the interior of the connecting block, releasing the locking of the connecting block, allowing the protective cover to be opened, and providing convenience for the wiring work of the terminal cover.

[0007] As a preferred technical solution of this application, the two outer walls of the connecting block are symmetrically provided with limiting holes, and the end of the fixing rod away from the sliding block is slidably inserted into the inside of the limiting hole, and the outer diameter of the fixing rod is adapted to the inner diameter of the limiting hole.

[0008] By adopting the above technical solution, when the fixing rod is inserted into the limiting hole, the displacement of the connecting block is forcibly constrained by the tight fit between the hole wall and the rod body, so that the protective cover cannot shift or shake laterally after it is closed, and the locking position of the protective cover and the mounting bracket is completely fixed.

[0009] As a preferred technical solution of this application, the outer wall of the fixed seat is provided with an adjustment groove through the outer side of the sliding groove, and the adjustment block slides inside the adjustment groove.

[0010] By adopting the above technical solution, the adjusting block is exposed to the outside of the fixed seat through the adjusting groove, so that the operator can directly control the displacement of the internal sliding block through the external adjusting block. The existence of the adjusting groove can limit the movement path of the adjusting block and prevent the return spring from being damaged due to excessive stretching.

[0011] As a preferred technical solution of this application, the protective cover is shaped like an n and completely covers the several terminal covers inside it.

[0012] By adopting the above technical solution, the terminal cover is completely wrapped with a protective cover, effectively resisting impacts from above and the side, and providing safety protection for the terminal cover.

[0013] As a preferred technical solution of this application, the inner wall of the protective cover is fixedly connected with a number of reinforcing ribs evenly distributed along its length, and the reinforcing ribs are metal components.

[0014] By adopting the above technical solution, the structural strength of the protective cover is enhanced by setting reinforcing ribs, thereby improving the protective capability of the cover.

[0015] As a preferred technical solution of this application, the mounting frame consists of a U-shaped frame and a cover plate, and the cover plate is fixedly installed on the top of the U-shaped frame by fixing screws. Mounting blocks are fixedly connected to the outer walls on both sides of the U-shaped frame near the bottom, and mounting holes are opened through the upper surface of the mounting blocks.

[0016] By adopting the above technical solution, the U-shaped frame provides the main support frame, and the cover plate covers the top with fixing screws to form a detachable encapsulation structure, which facilitates quick disassembly and assembly of the transformer body inside. The mounting hole penetrates the upper surface of the mounting block and provides a bolt anchoring interface, so that the mounting frame can be installed on the base of the designated equipment.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] In this invention, the protective cover, installed via a hinge, can be opened and closed to cover the terminal cover, forming a physical barrier to directly prevent collision damage during transportation. After the connecting block is inserted into the placement slot of the fixing seat, the sliding blocks on both sides push the fixing rod into the interior of the connecting block under the action of the return spring, achieving automatic locking. The displacement of the sliding block can be manually controlled by the adjusting block to adjust the position of the fixing rod, allowing the fixing rod to be pulled out from the interior of the connecting block, releasing the locking of the connecting block, and allowing the protective cover to be opened, thus facilitating the wiring work of the terminal cover.

[0026] 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.

[0027] like Figure 1 - Figure 4 As shown, this embodiment provides a control transformer structure, including a mounting frame 1. A transformer body 2 is fixedly mounted inside the mounting frame 1. A terminal cover 3 electrically connected to the transformer body 2 is fixedly mounted on the upper surface of the mounting frame 1. A protective cover 5 is hinged to one side of the upper surface of the mounting frame 1 via a hinge 4. A connecting block 6 is fixedly connected to the outer wall of the protective cover 5 away from the hinge 4. A fixing seat 8 is fixedly mounted on the other side of the upper surface of the mounting frame 1. The top of the fixing seat 8 has a placement groove 9 for inserting the connecting block 6. A sliding groove 10 is formed inside the fixing seat 8. Sliding blocks 12 are symmetrically arranged on both sides of the placement groove 9 inside the sliding groove 10. A return spring 13 is fixedly connected between the two sliding blocks 12. The outer wall of the two sliding blocks 12 near the connecting block 6 is... A fixing rod 11 is fixedly connected to the wall, and the other end of the fixing rod 11 is slidably inserted into the interior of the connecting block 6. An adjusting block 14 is fixedly connected to the side wall of the sliding block 12. In use, the protective cover 5 installed by the hinge 4 can be opened and closed to cover the terminal cover 3, forming a physical barrier to directly avoid collision damage during transportation. After the connecting block 6 is inserted into the placement slot 9 of the fixing seat 8, the sliding blocks 12 on both sides push the fixing rod 11 into the interior of the connecting block 6 under the action of the return spring 13, realizing automatic locking. The displacement of the sliding block 12 can be manually controlled by the adjusting block 14 to adjust the position of the fixing rod 11, so that the fixing rod 11 can be pulled out from the interior of the connecting block 6, releasing the locking of the connecting block 6, so that the protective cover 5 can be opened, providing convenience for the wiring work of the terminal cover 3.

[0028] In this embodiment, as Figure 2 and 3As shown, limit holes 7 are symmetrically opened on both outer walls of the connecting block 6. The end of the fixing rod 11 away from the sliding block 12 is slidably inserted into the inside of the limit hole 7, and the outer diameter of the fixing rod 11 is matched with the inner diameter of the limit hole 7. When in use, when the fixing rod 11 is inserted into the limit hole 7, the displacement of the connecting block 6 is forcibly constrained by the tight fit between the hole wall and the rod body, so that the protective cover 5 cannot be laterally offset or shake after closing, ensuring that the locking position of the protective cover 5 and the mounting bracket 1 is completely fixed.

[0029] In this embodiment, as Figure 2 and 3 As shown, an adjustment groove 15 is provided through the outer wall of the fixed base 8 on the outside of the sliding groove 10. The adjustment block 14 slides inside the adjustment groove 15. In use, the adjustment block 14 is exposed to the outside of the fixed base 8 through the adjustment groove 15, so that the operator can directly control the displacement of the internal sliding block 12 through the external adjustment block 14. The existence of the adjustment groove 15 can limit the movement path of the adjustment block 14 and prevent the return spring 13 from being damaged due to excessive stretching.

[0030] In this embodiment, as Figure 1 As shown, the protective cover 5 is shaped like an n and completely covers several terminal covers 3 inside it. In use, the protective cover 5 completely wraps around the terminal covers 3, effectively resisting impacts from above and the sides and providing safety protection for the terminal covers 3.

[0031] In this embodiment, as Figure 2 As shown, the inner wall of the protective cover 5 is fixedly connected with several reinforcing ribs 16 evenly distributed along its length. The reinforcing ribs 16 are metal components. In use, the reinforcing ribs 16 are used to strengthen the structural strength of the protective cover 5 and improve its protective ability.

[0032] In this embodiment, as Figure 4 As shown, the mounting bracket 1 consists of a U-shaped frame 101 and a cover plate 102. The cover plate 102 is fixedly installed on the top of the U-shaped frame 101 by fixing screws 103. Mounting blocks 104 are fixedly connected to the outer walls on both sides of the U-shaped frame 101 near the bottom. Mounting holes 105 are provided through the upper surface of the mounting blocks 104. In use, the U-shaped frame 101 provides the main support frame, and the cover plate 102 covers the top by fixing screws 103, forming a detachable encapsulation structure, which facilitates quick disassembly and assembly of the transformer body 2 inside. The mounting holes 105 penetrate the upper surface of the mounting blocks 104, providing bolt anchoring interfaces, so that the mounting bracket 1 can be installed on the designated equipment base.

[0033] The working principle of this utility model is as follows: When using the control transformer structure of this application, the protective cover 5 is first hinged and installed on the top of the mounting frame 1 via the hinge 4. Then, the protective cover 5 is fixed. During the fixing process, the operator can manually control the sliding block 12 by pulling the adjusting block 14, so that the fixing rod 11 is completely retracted into the fixing seat 8. At this time, the protective cover 5 is rotated so that the connecting block 6 is inserted into the placement groove 9. Then, the adjusting block 14 is released, and the sliding blocks 12 on both sides will push the fixing rod 11 into the connecting block 6 under the action of the return spring 13, so as to achieve automatic locking. After the protective cover 5 is closed, it cannot be laterally offset or shaken, ensuring that the locking position of the protective cover 5 and the mounting frame 1 is completely fixed. At this time, the protective cover 5 will completely wrap the terminal cover 3, forming a physical barrier, effectively resisting the impact from above and the side, and ensuring that the terminal cover 3 will not be damaged by collision during transportation.
