[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] This utility model provides a technical solution: such as Figures 1 to 4 As shown, in this embodiment, the snap-fit ​​modular braking unit includes a frequency converter housing 1. A connecting plate 2 is bolted to the inner wall of the frequency converter housing 1. A vertical plate 3 is vertically slidably mounted on the surface of the connecting plate 2, and a horizontal plate 4 is horizontally slidably mounted on the surface of the vertical plate 3. Positioning clamps 5 are slidably mounted on both sides of the surface of the horizontal plate 4. A positioning groove 6 is formed inside the top of the positioning clamp 5. A braking unit body 7 is mounted on the surface of the positioning clamp 5. The braking unit body 7 is disposed inside the two positioning grooves 6 of the two positioning clamps 5, controlling the braking... The unit body 7 is installed inside the positioning slots 6 of the two positioning clamps 5 to realize the installation of the braking unit body 7. When the braking unit body 7 needs to be repaired and removed, the two positioning clamps 5 can be pushed away to move it, and the braking unit body 7 located between the two positioning clamps 5 can be removed. The installation and disassembly of the braking unit body 7 are convenient. After the braking unit body 7 is installed, the vertical plate 3 can be controlled to move vertically according to the installation position. At the same time, the horizontal plate 4 can be controlled to move horizontally, and the position of the braking unit body 7 installed on the horizontal plate 4 can be adjusted to increase the installation range of the braking unit body 7.

[0017] like Figures 1 to 4 As shown, limit rods 8 are fixedly installed on both sides of the surface of the horizontal plate 4, and limit holes 9 are opened at both ends of the positioning clamping plate 5. The limit rods 8 are slidably connected to the limit holes 9. A first return spring 10 is sleeved on the outer side of the end of the limit rod 8. One end of the first return spring 10 is fixedly connected to one end of the limit rod 8, and the other end of the first return spring 10 is fixedly connected to the outer side of the positioning clamping plate 5. A pressing slope 11 is opened at one corner of the top of the positioning clamping plate 5, and the braking unit body 7 is set to press and contact the pressing slope 11.

[0018] The control brake unit body 7 presses the pressing inclined surface 11 at one corner of the top of the positioning clamp 5, which will drive the positioning clamp 5 to move along the trajectory of the limit rod 8. The two positioning clamps 5 will move away from each other. At this time, the first return spring 10 is in a compressed state, which moves the brake unit body 7 between the two positioning clamps 5 and into contact with the surface of the horizontal plate 4. This is used to align the brake unit body 7 with the positioning slot 6. The push of the positioning clamps 5 by the first return spring 10 will drive the two positioning clamps 5 to move closer to each other. The brake unit body 7 will be stuck inside the positioning slot 6, thus realizing the installation of the brake unit body 7.

[0019] like Figures 1 to 4 As shown, a first guide rod 12 is fixedly installed on both sides of the surface of the connecting plate 2, a first guide hole 13 is opened at both ends of the vertical plate 3, the first guide hole 13 is slidably connected to the first guide rod 12, a second guide rod 14 is fixedly installed on both ends of the surface of the vertical plate 3, and a second guide hole 15 is opened at both ends of the horizontal plate 4, the second guide hole 15 is slidably connected to the second guide rod 14.

[0020] The vertical plate 3 can be controlled to move vertically along the trajectory of the first guide rod 12 according to the installation position. At the same time, the horizontal plate 4 can be controlled to move horizontally along the second guide rod 14, and the position of the braking unit body 7 installed on the horizontal plate 4 can be adjusted.

[0021] like Figures 1 to 4 As shown, a sliding hole 16 is provided in the middle of one end of the horizontal plate 4. A positioning rod 17 is slidably installed inside the sliding hole 16. A second return spring 18 is sleeved on the outer side of the end of the positioning rod 17. One end of the second return spring 18 is fixedly connected to one end of the positioning rod 17, and the other end of the second return spring 18 is fixedly connected to the surface of the horizontal plate 4. Positioning holes 19 are provided at equal intervals on the surface of the connecting plate 2. The end of the positioning rod 17 is slidably inserted into the positioning hole 19.

[0022] By pulling the end of the positioning rod 17 by the second return spring 18, the bottom end of the positioning rod 17 can be inserted into the positioning hole 19 at the designated position, thereby fixing the position of the braking unit body 7.

[0023] like Figures 1 to 4 As shown, the end of the positioning rod 17 away from the second return spring 18 has a chamfer 20.

[0024] The chamfer 20 design makes it easy for the bottom end of the positioning rod 17 to be inserted into the positioning hole 19.

[0025] This utility model provides a snap-fit ​​modular braking unit, the specific working principle of which is as follows: When the device is in use, the control brake unit body 7 presses the pressing inclined surface 11 at one corner of the top of the positioning clamp 5, which will drive the positioning clamp 5 to move along the trajectory of the limit rod 8. The two positioning clamps 5 will move away from each other. At this time, the first return spring 10 is in a compressed state, which moves the brake unit body 7 between the two positioning clamps 5 and into contact with the surface of the horizontal plate 4. This is used to align the brake unit body 7 with the positioning slot 6. The push of the positioning clamps 5 by the first return spring 10 will drive the two positioning clamps 5 to move closer to each other. The brake unit body 7 will be stuck in the positioning slot 6, thus realizing the installation of the brake unit body 7. When the brake unit body 7 needs to be repaired and removed, the two positioning clamps 5 will be pushed away from each other, and the brake unit body 7 located between the two positioning clamps 5 can be removed. The installation and disassembly of the brake unit body 7 are convenient. After the brake unit body 7 is installed, the vertical plate 3 can be controlled to move vertically along the trajectory of the first guide rod 12 according to the installation position. At the same time, the horizontal plate 4 can be controlled to move horizontally along the second guide rod 14. The position of the brake unit body 7 installed on the horizontal plate 4 can be adjusted. Meanwhile, the bottom end of the positioning rod 17 can be inserted into the positioning hole 19 at the designated position by the pull of the second return spring 18, which can fix the position of the brake unit body 7.
