[0002] With the development of society and technology, equipment in various fields has been greatly improved. A rectifier is a rectifying device, which is a device that converts AC into DC. It has two main functions: first, to convert AC into DC and supply it to the load or inverter after filtering; second, to provide charging voltage to the battery. In order to facilitate the installation of daily staff, it is generally necessary to adopt a corresponding installation and fixing structure, which greatly improves the installation efficiency.

[0003] After searching, the publication number CN218733924U, application date 2022.10.25 discloses a mounting and fixing structure of a transformer rectifier, including a connecting piece, a rectifier is arranged at the bottom of the connecting piece, two sets of reinforcing plates are welded on the left and right sides of the rectifier, and a bearing plate is mounted on the outer surface of the connecting piece, and a sealing block is symmetrically welded on the upper surface of the bearing plate. The mounting and fixing structure of the transformer rectifier is inserted into the interior of the rectifier through the plug-in plate, so that the first protective cover and the second protective cover can be more stably sleeved on the rectifier, so that the installation of the rectifier is stable, and the rectifier can be protected at the same time, which improves the use effect of the rectifier.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0034] See also Figures 1 to 4 The utility model is an installation and fixing structure of a transformer rectifier, comprising a left protective shell 1 and a right protective shell 2 installed on one side thereof, the inner sides of the front and rear end surfaces of the right protective shell 2 are fixedly connected with a right reinforcing plate 201, and a limiting component 3 is arranged at the center position of the upper surface of the right reinforcing plate 201; the limiting component 3 comprises a fixing frame 301 and an upper magnetic ring 3011 embedded and installed at the top end thereof, and a limiting plate 302 is arranged directly above the fixing frame 301.

[0035] Specifically, the inner sides of the front and rear end surfaces of the left protective shell 1 are fixedly connected with the left reinforcing plate 101, the rectifier body 103 is installed inside the left protective shell 1 and the right protective shell 2, the top of the rectifier body 103 is provided with a sealing structure 102, a through hole is opened at the center of the upper surface of the left reinforcing plate 101, a fixing plate 3012 is fixedly connected at the center of the inner wall of the fixing frame 301, a pull ring 3021 is fixedly connected at the center of the top of the limiting plate 302, and a connecting ring 3021 is fixedly connected at the center of the bottom of the limiting plate 302. The movable rod 303 and the bottom end of the connecting rod 303 pass through the through hole at the top center position of the fixed frame 301 and are connected to the movable plate 304. A lower magnetic ring 3041 is embedded in the outer side of the upper surface of the movable plate 304. A connecting rod 305 is fixedly connected to the bottom center position of the movable plate 304. The other end of the connecting rod 305 passes through the through hole at the center position of the upper surface of the fixed plate 3012 and is connected to the insertion rod 307. A spring 306 is sleeved on the outer side of the outer wall of the connecting rod 305, and the spring 306 is located between the fixed plate 3012 and the insertion rod 307.

[0036] Furthermore, the left protective shell 1, the right protective shell 2, the left reinforcing plate 101, the right reinforcing plate 201 and the sealing structure 102 are all prior arts, so they are not elaborated here. The limit plate 302 and the movable plate 304 are connected by the connecting rod 303, which plays a role of connecting transmission. Under the action of the connecting rod 305, the movable plate 304 and the insertion rod 307 are connected, which plays a role of connecting transmission. The elastic performance of the spring 306 can drive the insertion rod 307 to move, and the insertion rod 307 can be fixed at the top under the magnetic attraction of the upper magnetic ring 3011 and the lower magnetic ring 3041.

[0037] The operation process of this embodiment is as follows: first, the rectifier body 103 is placed inside the left protective shell 1 and the right protective shell 2, and then the pull ring 3021 is pulled upward, and the pull ring 3021 is forced to drive the limit plate 302 to move, and the inner wall of the limit plate 302 is connected to the movable plate 304 through the connecting rod 303. Therefore, when the limit plate 302 moves, the movable plate 304 is driven to move under the action of the connecting rod 303, wherein the bottom of the movable plate 304 is connected to the plug rod 307 through the connecting rod 305, so when the movable plate 304 moves, the plug rod 307 is driven to move upward under the action of the connecting rod 305, and The spring 306 is squeezed. At this time, the movable plate 304 is attracted to the inner top of the fixed frame 301 by the magnetic attraction of the upper magnetic ring 3011 and the lower magnetic ring 3041. Then the left reinforcing plate 101 is clamped at the bottom of the right reinforcing plate 201, and then the force on the pull ring 3021 is stopped. At this time, the insertion rod 307 is rebounded to the initial position under the elastic performance of the spring 306, and is inserted into the through hole on the surface of the left reinforcing plate 101, which plays a role of limiting. The same is true during disassembly, which makes it convenient for the staff to quickly disassemble and assemble the left protective shell 1 and the right protective shell 2, saving time and effort and improving work efficiency. Specific embodiment 2

[0039] See also Figure 2 , 5 6. Based on the specific embodiment 1, what is different from the first embodiment is that: a heat dissipation component 4 is provided, and the heat dissipation component 4 includes a heat dissipation frame 401 and a heat absorbing plate 402 installed on the top thereof, and a heat sink 4021 is provided at the bottom of the heat absorbing plate 402, which solves the existing problem that the internal temperature of the rectifier increases when it is working, thereby affecting the normal use and service life of the equipment.

[0040] Specifically, the bottom of the outer walls on both sides of the heat dissipation frame 401 are provided with a mounting frame 403 , the inner side of the mounting frame 403 is installed with a motor 404 , and the output shaft of the motor 404 is installed with a fan blade 4041 .

[0041] Furthermore, the heat absorbing plate 402 can absorb the heat generated by the rectifier body 103 during operation, and dissipate the heat to the multiple heat sinks 4021 . The operation of the motor 404 can drive the fan blades 4041 to rotate, thereby achieving the purpose of discharging the heat in the heat absorbing plate 402 and the heat sink 4021 .

[0042] The operation process of this embodiment is as follows: after the rectifier body 103 is installed inside the left protective shell 1 and the right protective shell 2 and used, the heat generated during the operation of the rectifier body 103 will be absorbed by the heat absorption plate 402 located at the bottom thereof, and dissipated to the multiple heat sinks 4021 at the bottom thereof, and then the motors 404 on both sides are started, and the output shaft of the motor 404 rotates to drive the fan blades 4041 to rotate, thereby forming an air duct in one direction and dissipating the heat on the heat sink 4021, thereby playing a role in heat dissipation, with high heat dissipation efficiency and good effect.
