Description

Technical Field

[0001] This utility model relates to the field of frequency converter technology, and more specifically, to a frequency converter mounting structure and a frequency converter. Background Technology

[0002] The invention of frequency converters stemmed from the need for stepless speed regulation in AC motors. With the emergence of components such as thyristors, electrostatic induction transistors, and high-voltage insulated-gate bipolar thyristors, electrical technology has undergone rapid changes, and frequency converter speed control technology has developed accordingly. In particular, pulse-width modulation (PWM) variable frequency speed control technology has propelled frequency converters to new heights. However, with the continuous expansion of power electronics technology applications, frequency converters have gradually penetrated into various industrial sectors. Therefore, the market demands higher performance from frequency converters, and the number of frequency converter manufacturers is increasing. Improving product competitiveness has become a crucial development direction for enterprises. Currently, frequency converters often require screws to be fixed to the installation site for use.

[0003] Currently, when frequency converters are installed inside the cabinet with bolts, their positions are fixed and cannot be adjusted. If other components or wiring need to be installed inside the cabinet, the inability to move the frequency converter can easily hinder these operations. Utility Model Content

[0004] The purpose of this utility model is to address the problem that the existing inverter installation structure cannot adjust the installation position of the inverter, which hinders the installation of other components and the wiring layout.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0006] A frequency converter mounting structure includes a mounting rail and a movable base slidably disposed on the top and bottom of the mounting rail, and further includes:

[0007] The installation mechanism includes a crank rod disposed on the top of the movable seat, a pressure plate disposed at one end of the crank rod located outside the movable seat, a limiting post disposed at the bottom of the pressure plate, a support plate disposed on the surface of the mounting rail, and several limiting sleeves disposed on the surface of the support plate and cooperating with the limiting post.

[0008] A pressing assembly is disposed at the end of the crank located inside the moving seat, for driving the crank to move vertically.

[0009] As a preferred technical solution of this application, the movable seat has a first chamber and a second chamber that are interconnected inside. The first chamber and the second chamber are provided with a transmission medium. The extrusion assembly includes a first pressure plate that is slidably disposed on the inner wall of the first chamber, a second pressure plate that is slidably disposed on the inner wall of the second chamber, a pressure column disposed on the top of the first pressure plate and extending outward through the top of the movable seat, and a finger pressure plate disposed on the top of the pressure column. The end of the crank rod located inside the movable seat is connected to the top of the second pressure plate.

[0010] As a preferred technical solution of this application, the vertical section of the crank rod located inside the moving seat is fitted with a compression spring.

[0011] As a preferred technical solution of this application, the top and bottom of the mounting rail are provided with sliding grooves, and the inner wall of the movable seat is provided with a number of balls that cooperate with the sliding grooves.

[0012] As a preferred technical solution of this application, the bottom of the limiting post is provided with a plug with a cone-shaped structure.

[0013] As a preferred technical solution of this application, protective pads are provided at both ends of the mounting rail.

[0014] As a preferred technical solution of this application, the two ends of the mounting rail are also provided with positioning plates, and bolts are threadedly connected to the surface of the positioning plates.

[0015] This application also discloses a frequency converter, including the frequency converter mounting structure described in any of the above claims, and a frequency converter body disposed between two movable seats.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. By using the positioning plate and bolts, the mounting rail can be fixed to the inner wall of the cabinet. Then, by using the compression component, when the position of the frequency converter needs to be adjusted, simply press the pressure plate with your finger to move the first pressure plate downward. At this time, the medium inside the moving seat can drive the second pressure plate upward, which in turn drives several limit posts to move upward and disengage from the limit sleeve. At this time, the sliding moving seat can adjust the position of the frequency converter. Finally, release the pressure plate, and the transmission medium drives the first and second pressure plates to reset, which can drive the limit posts to move downward and insert into the limit sleeve to fix the moving seat and the frequency converter. This solves the problem in the existing technology that the installation position of the frequency converter cannot be adjusted, which makes it inconvenient for personnel to install other components and arrange wiring inside the cabinet.

[0018] 2. When the sliding seat is in motion, the ball bearings set on the inner wall of the sliding seat can roll in the groove on the mounting rail, which can reduce the friction between the sliding seat and the mounting rail, making it easier for the sliding seat to slide stably on the mounting rail without jamming, thus further facilitating the adjustment of the inverter's installation position.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0027] like Figure 1 , Figure 2 and Figure 3As shown, this embodiment proposes a frequency converter installation structure, including an installation rail 1 and a movable seat 2 slidably disposed on the top and bottom of the installation rail 1, and also includes an installation mechanism 3 and a pressing assembly 4: The installation mechanism 3 includes a crank 301 disposed on the top of the movable seat 2, a pressure plate 302 disposed on one end of the crank 301 located outside the movable seat 2, a limiting post 303 disposed on the bottom of the pressure plate 302, a support plate 304 disposed on the surface of the installation rail 1, and a plurality of limiting sleeves 305 disposed on the surface of the support plate 304 and cooperating with the limiting post 303. The pressing assembly 4 is disposed on the end of the crank 301 located inside the movable seat 2, and is used to drive the crank 301 to move vertically. The two ends of the installation rail 1 are also provided with positioning plates 6, and bolts 601 are threadedly connected to the surface of the positioning plates 6.

[0028] When the inverter needs to be installed, the mounting rail 1 can be fixed to the inner wall of the cabinet by using the bolts 601 on the positioning plate 6 and the threaded holes on the inner wall of the cabinet. The inverter will also be fixed inside the cabinet along with the mounting rail 1. When the position of the inverter needs to be adjusted, the crank rod 301 inside the moving base 2 can be moved vertically upward by the set pressing component 4. At this time, the crank rod 301 will drive several limit posts 303 to move upward and disengage from the limit sleeve 305 through the pressure plate 302. In this way, the personnel can slide the inverter back and forth on the mounting rail 1 as needed to adjust the installation position of the inverter. This makes it easy for personnel to install other components and lay out the wiring without being obstructed by the inverter. After the inverter is moved to the appropriate position, the set pressing component 4 can drive the crank rod 301 to move downward and reset, thereby driving the limit posts 303 to move downward and insert into the limit sleeve 305, thus completing the re-fixation of the moving base 2 and the inverter.

[0029] The bottom of the limiting post 303 is provided with a plug 3031 with a cone-shaped structure; when the limiting post 303 moves downward to reset, the cone-shaped plug 3031 makes it easier for the limiting post 303 to be inserted more stably into the limiting sleeve 305 to complete the limiting operation of the moving seat 2 and the frequency converter.

[0030] like Figure 4 and Figure 5As shown, the movable seat 2 further comprises a first chamber 201 and a second chamber 202 that are interconnected. The first chamber 201 and the second chamber 202 contain a transmission medium. The extrusion assembly 4 includes a first pressure plate 401 that is slidably disposed on the inner wall of the first chamber 201, a second pressure plate 404 that is slidably disposed on the inner wall of the second chamber 202, a pressure column 402 that is disposed on the top of the first pressure plate 401 and extends outward through the top of the movable seat 2, and a finger pressure plate 403 that is disposed on the top of the pressure column 402. The end of the crank rod 301 located inside the movable seat 2 is connected to the top of the second pressure plate 404. A compression spring 5 is sleeved on the vertical section of the crank rod 301 located inside the movable seat 2.

[0031] When the inverter needs to be moved, the operator presses the acupressure plate 403 to move the first pressure plate 401 at the bottom of the pressure column 402 upward, squeezing the transmission medium inside the first chamber 201. After being compressed, the transmission medium is forced into the second chamber 202, and squeezes the second pressure plate 404 upward, pushing the crank 301 up, thereby causing the limit column 303 to move upward and disengage from the limit sleeve 305. Moreover, when the second pressure plate 404 moves upward, it also causes the compression spring 5 to compress. After the position of the moving seat 2 and the inverter is adjusted, the operator releases the acupressure plate 403. At this time, the transmission medium flows back, and with the rebound reset of the compression spring 5, the second pressure plate 404 can be moved downward and reset, making it easy for the limit column 303 to re-insert into the limit sleeve 305. It should be noted that the transmission medium can be water or hydraulic oil or other liquids.

[0032] like Figure 2 and Figure 3 As shown, in a preferred embodiment, based on the above method, the top and bottom of the mounting rail 1 are provided with sliding grooves 101, and the inner wall of the movable seat 2 is rotatably provided with a number of balls 203 that cooperate with the sliding grooves 101.

[0033] When the sliding seat 2 is slidable, the ball bearings 203 on the inner side of the sliding seat 2 will roll in the groove 101 on the mounting rail 1, which can reduce the friction between the sliding seat 2 and the mounting rail 1, so that the sliding seat 2 can slide more stably on the mounting rail 1 without jamming.

[0034] In addition, protective pads 7 are provided at both ends of the mounting rail 1; when the frequency converter is slid back and forth, when the frequency converter is slid to the edge of the mounting rail 1, the protective pads 7 can block the frequency converter and prevent it from colliding with the inner wall of the cabinet or other components and being damaged.

[0035] like Figure 1 and Figure 2As shown, as a preferred embodiment, based on the above method, this application further discloses a frequency converter, including the frequency converter mounting structure mentioned in any of the above embodiments, and also including a frequency converter body 8, which is disposed between two movable seats 2; by connecting the frequency converter body 8 to the mounting rail 1, not only can the frequency converter body 8 be installed and fixed, but the installation position of the frequency converter body 8 can also be adjusted.

[0036] The working principle of this utility model is as follows: When the inverter needs to be installed, the mounting rail 1 can be fixed to the inner wall of the cabinet by using the bolts 601 on the positioning plate 6 and the threaded holes on the inner wall of the cabinet. The inverter will also be fixed inside the cabinet along with the mounting rail 1. When the position of the inverter needs to be adjusted, the operator presses the pressure plate 403 to move the first pressure plate 401 at the bottom of the pressure column 402 upward to squeeze the transmission medium inside the first chamber 201. After being compressed, the transmission medium will be forced into the second chamber 202, and the second pressure plate 404 will be squeezed upward to move the crank rod 30. 1. Lifting up causes the limit post 303 to move upward and disengage from the limit sleeve 305. This allows personnel to slide the inverter back and forth on the mounting rail 1 as needed, adjusting the inverter's installation position. This ensures that personnel are not obstructed when installing other components or laying out wiring. In addition, when sliding the movable seat 2, the ball bearings 203 on the inner side of the movable seat 2 will roll in the groove 101 on the mounting rail 1, thus reducing the friction between the movable seat 2 and the mounting rail 1. This allows the movable seat 2 to slide more stably on the mounting rail 1 without jamming.

[0037] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
