Description

Technical Field

[0001] This utility model belongs to the field of transformer rectifier installation technology, and in particular relates to a transformer rectifier that is easy to install and disassemble. Background Technology

[0002] There are now transformer-rectifier integrated devices that integrate the functions of a transformer and a rectifier into one unit. Internally, they achieve alternating current transformation and rectification through a reasonable circuit layout and connection.

[0003] Since rectifiers are typically installed in the cabinet using multiple mounting screws, this adds considerable inconvenience to maintenance and disassembly. Installers need to remove each screw one by one, maintain or replace the old one, and then reinstall it in the cabinet, which increases the difficulty of the installation process. To address this, we have developed a transformer rectifier that is easy to disassemble and reassemble, solving the problems existing in the current technology. Summary of the Invention

[0004] The purpose of this utility model is to provide a transformer rectifier that is easy to disassemble and assemble, thereby reducing the difficulty of operation for installers and solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A transformer rectifier that is easy to disassemble and assemble includes a rectifier body disposed at the top of the inner cavity of a cabinet. A support plate is fixedly connected to the top of the inner cavity of the cabinet. The top of the support plate is slidably connected to the bottom of the rectifier body. A guide seat is slidably connected to the surface of a guide rail. The top of the guide seat is fixedly connected to the bottom of the rectifier body. A threaded limiting rod is slidably passed through the inner surface of the guide seat. A limiting cylinder is fixedly connected to the back of the inner cavity of the cabinet at a position corresponding to the threaded limiting rod. A guide block is fixedly connected to the surface of the threaded limiting rod. A guide groove is opened in the inner cavity of the limiting cylinder. An annular groove is opened on the inner surface of the limiting cylinder at a position communicating with the guide groove. The outer surface of the guide block can be slidably connected to the inner surfaces of the guide groove and the annular groove. A spring is fixedly connected to the back of the inner cavity of the limiting cylinder. A limiting plate is fixedly connected to the side of the spring away from the back of the inner cavity of the limiting cylinder. The threaded limiting rod and the limiting plate are tightly fitted together.

[0006] Preferably, a fastening nut is threaded onto the surface of the threaded limiting rod and extends through the outer side of the guide seat. When the fastening nut is engaged between the threaded limiting rod and the limiting cylinder, it is tightly fitted to one end face of the guide seat.

[0007] Preferably, an arc-shaped block is fixedly connected to the end face of the threaded limiting rod near the limiting cylinder, and an arc-shaped surface that fits and conforms to the arc-shaped block is formed on the inner surface of the limiting plate.

[0008] Preferably, a limiting post is fixedly connected to both the back side of the inner cavity of the limiting cylinder and the axis of the limiting plate, and the limiting post is sleeved on the inner surface of the spring.

[0009] Preferably, the guide groove and the annular groove are designed to be connected to each other at a 90-degree angle, and the guide groove extends through one end face of the limiting cylinder.

[0010] The beneficial effects of this utility model are:

[0011] 1. In this utility model, the guide seat slides on the outer surface of the guide rail. After the rectifier body is pushed to the appropriate position, the threaded limiting rod is inserted into the corresponding limiting cylinder. The threaded limiting rod is slidably connected to the inner surface of the guide groove through the guide block, and the end face of the threaded limiting rod presses the end face of the limiting plate, and is compressed and limited by the spring. When the guide block slides to the end of the guide groove, the threaded limiting rod is rotated counterclockwise, so that the guide block slides into the corresponding annular groove, so that the threaded limiting rod is locked on the inner surface of the limiting cylinder, thereby limiting and fixing the position of the rectifier body. When it needs to be removed, simply rotate the threaded limiting rod clockwise, so that the guide block rotates to the inner surface of the guide groove, and the threaded limiting rod pops out by the elasticity of the spring. By setting the above structure, the purpose of convenient disassembly and assembly can be achieved, reducing the difficulty of operation for installers.

[0012] 2. This utility model prevents the threaded limit rod from rotating by setting a fastening nut to fasten the thread on the outer surface of the threaded limit rod, thus limiting the position of the threaded limit rod;

[0013] 3. By setting the surface of the arc-shaped block to fit tightly against the arc-shaped surface, this utility model can facilitate the rotation of the end face of the threaded limit rod and reduce the resistance to the rotation of the threaded limit rod.

[0014] 4. This utility model provides a limiting post on the inner surface of the spring, which can limit and support the position of the spring and prevent the spring from tilting too much. Attached Figure Description

[0022] In the following description, embodiments of the easily disassembled transformer rectifier of the present invention will be described with reference to the accompanying drawings. Example 1:

[0023] Figure 1-4This invention illustrates an embodiment of a transformer rectifier for easy assembly and disassembly, comprising a rectifier body 5 disposed at the top of the inner cavity of a cabinet 1. A support plate 2 is fixedly connected to the top of the inner cavity of the cabinet 1, and the top of the support plate 2 is slidably connected to the bottom of the rectifier body 5. A guide seat 4 is slidably connected to the surface of a guide rail 3, and the top of the guide seat 4 is fixedly connected to the bottom of the rectifier body 5. A threaded limiting rod 6 slides through the inner surface of the guide seat 4, and a fastening nut 13 is threadedly connected to the surface of the threaded limiting rod 6 and through the outer side of the guide seat 4. When the fastening nut 13 is engaged between the threaded limiting rod 6 and the limiting cylinder 7, it is tightly fitted to one end face of the guide seat 4. The fastening nut 13 is installed on the outer surface of the threaded limit rod 6 to prevent rotation of the threaded limit rod 6 and limit its position. An arc-shaped block is fixedly connected to the end face of the threaded limit rod 6 near the limit cylinder 7. The inner surface of the limit plate 12 has an arc-shaped surface that fits and conforms to the arc-shaped block. By ensuring that the surface of the arc-shaped block fits tightly against the arc-shaped surface, the end face of the threaded limit rod 6 can rotate easily, reducing the resistance to rotation. The limit cylinder 7 is fixedly connected to the back of the inner cavity of the cabinet 1 at a position corresponding to the threaded limit rod 6. A guide block 8 is fixedly connected to the surface of the threaded limit rod 6. The inner cavity of the limit cylinder 7 is open A guide groove 9 is provided, and an annular groove 10 is formed on the inner surface of the limiting cylinder 7 at a position communicating with the guide groove 9. The outer surface of the guide block 8 can slide with the inner surfaces of the guide groove 9 and the annular groove 10. A spring 11 is fixedly connected to the back of the inner cavity of the limiting cylinder 7. A limiting plate 12 is fixedly connected to the side of the spring 11 away from the back of the inner cavity of the limiting cylinder 7. The threaded limiting rod 6 is tightly fitted with the limiting plate 12, and the guide seat 4 is slid on the outer surface of the guide rail 3. When the rectifier body 5 is pushed to an appropriate position, the threaded limiting rod 6 is inserted into the corresponding limiting cylinder 7. The threaded limiting rod 6 is slidably connected to the inner surface of the guide groove 9 through the guide block 8 and the threaded limiting rod 6 is slidably connected to the inner surface of the guide groove 9 through the guide block 8. The end face of the positioning rod 6 presses against the end face of the limiting plate 12 and is compressed and limited by the spring 11. When the guide block 8 slides to the end of the guide groove 9, the threaded limiting rod 6 is rotated counterclockwise, so that the guide block 8 slides into the corresponding annular groove 10, thereby making the threaded limiting rod 6 engage with the inner surface of the limiting cylinder 7, thus limiting and fixing the position of the rectifier body 5. When it needs to be removed, simply rotate the threaded limiting rod 6 clockwise, so that the guide block 8 rotates to the inner surface of the guide groove 9, and the threaded limiting rod 6 pops out due to the elasticity of the spring 11. By setting the above structure, the purpose of convenient disassembly and assembly can be achieved, reducing the difficulty of operation for installers. Example 2:

[0024] Figure 1-4This invention illustrates an embodiment of a transformer rectifier that is easy to assemble and disassemble. It includes a rectifier body 5 disposed at the top of the inner cavity of a cabinet 1. A support plate 2 is fixedly connected to the top of the inner cavity of the cabinet 1, and the top of the support plate 2 is slidably connected to the bottom of the rectifier body 5. A guide seat 4 is slidably connected to the surface of a guide rail 3, and the top of the guide seat 4 is fixedly connected to the bottom of the rectifier body 5. A threaded limiting rod 6 is slidably passed through the inner surface of the guide seat 4. A limiting cylinder 7 is fixedly connected to the back of the inner cavity of the cabinet 1 at a position corresponding to the threaded limiting rod 6. A guide block 8 is fixedly connected to the surface of the threaded limiting rod 6. A guide groove 9 is formed in the inner cavity of the limiting cylinder 7, and a ring is formed on the inner surface of the limiting cylinder 7 at a position communicating with the guide groove 9. The groove 10, guide groove 9 and annular groove 10 are designed to be interconnected at a 90-degree angle. The guide groove 9 passes through one end face of the limiting cylinder 7. The outer surface of the guide block 8 can be slidably connected to the inner surface of the guide groove 9 and the annular groove 10. A spring 11 is fixedly connected to the back of the inner cavity of the limiting cylinder 7. A limiting plate 12 is fixedly connected to the side of the spring 11 away from the back of the inner cavity of the limiting cylinder 7. A limiting post is fixedly connected to the back of the inner cavity of the limiting cylinder 7 and the axis of the limiting plate 12. The limiting post is sleeved on the inner surface of the spring 11. By setting the limiting post sleeved on the inner surface of the spring 11, the position of the spring 11 can be limited and supported to prevent the spring 11 from tilting too much. The threaded limiting rod 6 is tightly fitted with the limiting plate 12.

[0025] Working principle: When using this invention, the user slides the guide seat 4 onto the outer surface of the guide rail 3. After the rectifier body 5 is pushed to the appropriate position, the threaded limiting rod 6 is inserted into the corresponding limiting cylinder 7. The threaded limiting rod 6 is slidably connected to the inner surface of the guide groove 9 via the guide block 8, and the end face of the threaded limiting rod 6 presses against the end face of the limiting plate 12, and is compressed and limited by the spring 11. When the guide block 8 slides to the end of the guide groove 9, the threaded limiting rod 6 is rotated counterclockwise, thereby causing the guide block 8 to slide into the corresponding annular groove 10. This allows the threaded limiting rod 6 to engage with the inner surface of the limiting cylinder 7, thereby limiting and fixing the position of the rectifier body 5. By tightening the threaded nut 13 onto the outer surface of the threaded limiting rod 6, rotation of the threaded limiting rod 6 can be prevented, thus limiting its position. When removal is required, simply rotate the threaded limiting rod 6 clockwise, causing the guide block 8 to rotate to the inner surface of the guide groove 9. Then, through the elasticity of the spring 11, the threaded limiting rod 6 pops out, achieving convenient disassembly and assembly and reducing the difficulty of operation for installers.
