Detailed Description of the Embodiment

[0023] The following further describes the present application in detail with reference to the drawings.

[0024] The embodiment of the present application discloses an efficient and fast-switching EPS power supply.

[0025] Refer to Figure 1 , Figure 2 , the efficient and fast-switching EPS power supply includes a cabinet body 1 and a control box 2 installed in the cabinet body 1. A horizontally arranged placement rack 3 is fixedly installed in the cabinet body 1. A horizontally placed bidirectional lead screw 30 is rotatably arranged at the bottom of the placement rack 3. The length direction of the bidirectional lead screw 30 extends along the width direction of the cabinet body 1. Opposite external threads are symmetrically arranged at both ends of the bidirectional lead screw 30. Sliding racks 4 are symmetrically arranged at both ends of the bidirectional lead screw 30. The bottom of the sliding rack 4 is threadedly connected to the outside of the bidirectional lead screw 30. The two sliding racks 4 are slidably arranged on the placement rack 3 along the length direction of the bidirectional lead screw 30. The top of the sliding rack 4 extends upward to the front and rear sides of the placement rack 3. By rotating the bidirectional lead screw 3, the two sliding racks 4 will slide synchronously in the direction of approaching or separating from each other.

[0026] As Figure 2 , Figure 3As shown, a plurality of mounting grooves 42 are provided on the sliding frame 4 above the placement rack 3. The mounting grooves 42 are symmetrically arranged on the opposite outer side walls of the sliding frame 4, and the mounting grooves 42 on the same side of the sliding frame 4 are arranged at intervals in the height direction of the sliding frame 4. A clamping plate 40 for clamping and fixing the left and right sides of the control box 2 is detachably mounted on the sliding frame 4 through the mounting grooves 42. The front and rear sides of the clamping plate 40 are respectively inserted into the respective opposite mounting grooves 42 from top to bottom. The clamping plate 40 is fixedly mounted on the placement rack 3.

[0027] As Figure 3 , Figure 4 shown, a pin member 44 is movably inserted through the sliding frame 4 in the horizontal direction. A plurality of pin holes 400 for allowing the respective opposite pin members 44 to pass through the clamping plate 40 are provided through the clamping plate 40. The pin holes 400 on the same side of the clamping plate 40 are arranged at intervals in sequence along the direction in which the clamping plate 40 is inserted into the mounting groove 42. A return spring 45 sleeved outside the pin member 44 is provided on the sliding frame 4. The return spring 45 is located inside the sliding frame 4 and expands and contracts along the moving direction of the pin member 44 on the sliding frame 4. One end of the return spring 45 abuts against the pin member 44, and the other end of the return spring 45 abuts against the inner side wall of the sliding frame 4. In the natural state, the return spring 45 is used to push the pin member 44 to be inserted tightly into the opposite pin hole 400. Through the mutual insertion and cooperation of the pin member 44 and the pin hole 400, the clamping plate 40 can be locked on the sliding frame 4.

[0028] When installing the clamping plate 40, first insert the clamping plate 40 into the respective opposite mounting grooves 42 from top to bottom, and finally insert the pin member 44 into the pin hole 400. Through the mutual insertion and cooperation of the pin member 44 and the pin hole 400, the clamping plate 40 can be smoothly installed and fixed on the sliding frame 4, and the installation process is very convenient and fast.

[0029] As Figure 2 , Figure 3 shown, the control box 2 is placed on the placement rack 3, and the two clamping plates 40 are used to clamp and fix the control box 2 on the placement rack 3. A plug-in member 401 is also fixedly installed on the sliding frame 4, and the clamping plates 40 are respectively located above and below the plug-in member 401. A partition plate 41 is horizontally installed between the two sliding frames 4 at the same height. A plurality of plug holes 410 for allowing the respective opposite plug-in members 401 to be inserted into the partition plate 41 are provided through the partition plate 41. The plug holes 410 on the same side of the partition plate 41 are arranged at intervals in sequence along the sliding direction of the sliding frame 4. The plug-in member 401 is inserted into the opposite plug hole 410 from bottom to top, and the partition plate 41 is fixedly installed above the plug-in member 401.

[0030] As Figure 2 , Figure 3As shown, two pressing plates 43 are fixedly installed on the outer side wall of the top of the clamping plate 40 located on the top layer. The pressing plates 43 are symmetrically arranged on the front and rear sides of the clamping plate 40. The pressing plates 43 are in contact with the outer side wall of the top of the control box 2 placed on the partition plate 41. The partition plate 41 can be used for the control boxes 2 to be stacked in sequence along the height direction of the cabinet body 1, further optimizing the layout of the placement rack 3 and expanding the installable area of the placement rack 3. In addition, under the limitation of the pressing plates 43, the limiting and fixing effect on the top control box 2 can be further improved, enabling the top control box 2 to be installed on the partition plate 41 more stably and firmly.

[0031] As Figure 2 , Figure 3 shown, two limiting frames 46 are integrally formed on the upper surface of the partition plate 41. The limiting frames 46 are symmetrically arranged on the left and right sides of the control box 2. Under the limitation of the two-sided limiting frames 46, it can effectively prevent the situation that the control box 2 accidentally falls from the left and right sides of the placement rack 3 when the control box 2 is installed.

[0032] The implementation principle is as follows: When the specification size of the control box 2 to be installed changes, by rotating the bidirectional lead screw 30, the two sliding frames 4 are driven to move towards each other or away from each other until the distance between the two sliding frames 4 is adjusted to match the specification of the control box 2, and then the control box 2 is placed on the placement rack 3. Then, by rotating the bidirectional lead screw 30 again until the two clamping plates 40 clamp and fix the control box 2. At this time, the control box 2 can be successfully fixed and installed on the placement rack 3 under the clamping and fixing of the two clamping plates 40. The entire adjustment process is convenient and fast, greatly improving the installation efficiency.

[0033] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
