[0002] In the prior art, for example, a utility model with application number 202121366588.4 discloses a mounting bracket for a frequency converter. In order to solve the troublesome problem of having to re-set the fixing position when replacing frequency converters of different sizes, the frequency converter is installed and fixed by using the elastic force of a spring to control the first limit plate to squeeze and position the front end of the frequency converter during installation, which makes it easy to install and disassemble the frequency converter.

[0003] Similar to the above application, there are still some shortcomings:

[0004] Due to the different widths of different inverters, although the limit plate can be used to apply pressure to the front end of the inverter to fit the inverter to the rear plate during positioning, it is impossible to squeeze and limit the left and right sides of the inverter, resulting in low installation stability. In addition, the structure of the device is complex, and production and use are inconvenient;

DETAILED DESCRIPTION

[0024] In order to make the technical solution of the utility model more clear and specific to those skilled in the art, the utility model is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the utility model are not limited thereto.

[0025] like Figure 1-Figure 4 As shown, the present embodiment provides a mounting frame for a high-stability frequency converter, comprising a base plate 1, a side plate 2 being vertically provided at one end of the top of the base plate 1, limit rods 3 being symmetrically provided at the top and bottom of the side plate 2 close to the base plate 1, a U-shaped plate 4 being rotatably installed between the two groups of limit rods 3 at the top and bottom of the side plate 2, a sleeve 5 being fixed at the end of the U-shaped plate 4, the sleeve 5 being sleeved on the limit rod 3, a torsion spring 6 being provided at the end of the limit rod 3, the limit rod 3 passing through the middle of the torsion spring 6, one end of the torsion spring 6 being respectively installed on the U-shaped plate 4, the other end of the torsion spring 6 being fixed on the side plate 2, a first elastic band 7 being obliquely provided at the inner corners of the two groups of U-shaped plates 4, and a reinforcement mechanism being provided between the two groups of U-shaped plates 4.

[0026] The overall working principle is as follows: before installing the inverter, the position of the base plate 1 is fixed first. In the initial state, the torsion spring 6 applies elastic force to the U-shaped plate 4. The middle positions of the two groups of U-shaped plates 4 are overlapped and stuck in the middle of the side plate 2. When installing the inverter, the U-shaped plates 4 on both sides are unfolded outward, and then the inverter is placed on the top of the base plate 1. At the same time, the bottom end of the inverter is also located inside the bottom U-shaped plate 4. Then the U-shaped plate 4 is loosened and pressed against the front end of the inverter under the elastic force of the torsion spring 6, so that the inverter is tightly fitted to the side plate 2. At the same time, the first elastic band 7 is also pressed against both sides of the front end of the inverter to stabilize the position of the inverter. In addition, the two groups of U-shaped plates 4 are connected by a reinforcement mechanism to ensure the pressing effect of the U-shaped plate 4 on the front end surface of the inverter.

[0027] In this embodiment, the ends of the U-shaped plate 4 are provided with a slot that matches the end of the torsion spring 6, and a limiting ring that matches the torsion spring 6 is fixed on the side plate 2, and the end of the torsion spring 6 is inserted into the interior of the limiting ring.

[0028] Local working principle: During the installation of the torsion spring 6, it is first inserted horizontally into the limiting rod 3. At this time, one end of the torsion spring 6 is inserted into the inside of the limiting ring, and then the other end of the torsion spring 6 is compressed and stuck in the inside of the slot to stabilize the position of the torsion spring 6. After installation, the torsion spring 6 has a certain elastic force on the U-shaped plate 4.

[0029] In this embodiment, a rubber pad is provided on the top of the bottom plate 1, and a frosted layer is provided on the top of the rubber pad.

[0030] Local working principle: After the inverter is placed on the top of the rubber pad, there is greater friction between the inverter and the rubber pad, and the stability is higher.

[0031] In this embodiment, the middle of the U-shaped plate 4 is arc-shaped toward one side of the side plate 2 .

[0032] Partial working principle: After the U-shaped plate 4 is pressed against the front end of the inverter, the arcs on the U-shaped plate 4 are clamped on both sides of the front end of the inverter to stabilize the position of the inverter.

[0033] In this embodiment, the reinforcement mechanism includes a second elastic band 13, a hook 14 and a hanging ring 15. The second elastic band 13 is fixed to one end of the U-shaped plate 4. The bottom end of the second elastic band 13 is fixed with a hook 14. The hanging ring 15 is fixed to the other end of the U-shaped plate 4. The positions of the hooks 14 and the hanging rings 15 on the two groups of U-shaped plates 4 correspond to each other.

[0034] Partial working principle: When reinforcing the U-shaped plate 4 , the second elastic belt 13 is pulled to hook the hook 14 onto the hanging ring 15 , and the second elastic belt 13 applies tension to the U-shaped plate 4 to ensure the stability of the U-shaped plate 4 .

[0035] In this embodiment, the side panel 2 includes a lower side panel 8, an upper side panel 9, a sliding rod 10 and a screw 11. The lower side panel 8 is fixed to the top of the base panel 1, and an upper side panel 9 is provided on the top of the lower side panel 8. A sliding rod 10 is slidably provided between the lower side panel 8 and the upper side panel 9, and a screw 11 is threadedly installed between the lower side panel 8 and the upper side panel 9.

[0036] Local working principle: During use, due to the different heights of the frequency converters, in order to adapt to different frequency converters, the screw 11 is rotated to control the lower side plate 8 and the upper side plate 9 to move toward or away from each other. When the lower side plate 8 and the upper side plate 9 move toward each other, the height of the device is lowered to adapt to shorter frequency converters. When the lower side plate 8 and the upper side plate 9 move in opposite directions, the height of the device is increased to adapt to taller frequency converters.

[0037] In this embodiment, an adjusting block 12 is disposed at the middle position of the screw rod 11 , and anti-slip grooves are formed on the outer sides of the adjusting block 12 .

[0038] Partial working principle: When the screw rod 11 is rotationally adjusted, the rotation of the adjusting block 12 is manually controlled, which is easy to operate.

[0039] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
