Those who are familiar with the technology can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the present invention. , not all examples. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

As shown in FIG. 1 , the present invention provides a fixed connection structure for a power cabinet, which specifically includes a mounting seat 1 installed on a wall. The mounting seat 1 is provided with a sliding seat 2 that slides up and down, and the sliding seat 2 is provided with Two sets of symmetrically distributed bracket mechanisms 3 for holding up the power cabinet;

The top of the sliding seat 2 is provided with two sets of symmetrically distributed hinge frames 4, and the inner end of the hinge frame 4 is connected with the sliding seat 2 through the tension spring 5 provided at the bottom, and the outer end of the hinge frame 4 is provided with a side surface for squeezing the power cabinet. The sliding seat 2 slides down through the tension spring 5 to drive the outer ends of the two sets of hinged frames 4 to be clamped inward, while the two sets of hinged frames 4 clamp the power cabinet through the two sets of side pressure wheel mechanisms 6 .

This embodiment has the following beneficial effects:

(1) The power cabinet is held up by the mounting base 1 installed on the wall, so that the power cabinet does not need to have screw holes inside to be fixedly installed on the wall, thereby improving the sealing performance in the power cabinet and simplifying installation or disassembly Steps of the power cabinet;

(2) By setting the side pressing wheel mechanism 6 that grips the power cabinet with the bracket descending, the test power cabinet will be automatically snapped after being placed, and the power cabinet will be subject to increased weight as the components are installed in the power cabinet. The greater the clamping force of the side pressing wheel mechanism 6, the lower the probability of the power cabinet falling.

As shown in FIG. 1 to FIG. 3 , the bracket mechanism 3 includes a connecting frame 301 fixedly connected with the sliding seat 2 , and the bottom end of the connecting frame 301 is movably installed with a box corner bracket 302 for holding up the bottom corner of the power cabinet, and the box The corner bracket 302 is provided with a box fixing mechanism 303 for fixing by pressing the side of the power cabinet.

The box fixing mechanism 303 includes a base plate 3031 vertically installed on the outer end of the box angle bracket 302. The center position of the base plate 3031 is connected with a horizontally distributed screw rod 3032 through a thread, and the inner end of the screw rod 3032 is connected with a screw for pressing the side of the power cabinet. Skid plate 3033.

The horizontal part of the connecting frame 301 is provided with a horizontally distributed rack 304, the horizontal part of the connecting frame 301 and the rack 304 pass through the box angle bracket 302 and are slidably connected with it. The gear bolts 3021 meshed with the bars 304 and the fixing bolts 3022 for pressing and fixing the connecting frame 301 .

A rotating shaft 401 is rotatably connected to the central position of the hinged frame 4 , and the two sets of hinged frames 4 are installed at the top corners of both ends of the mounting base 1 through the rotating shaft 401 .

The outer end portion of the hinge frame 4 is provided with card slots 402 distributed along the hinge frame 4 , and the card grooves 402 are movably connected with engaging bolts 403 for pressing the hinge frame 4 and installing the side pressing wheel mechanism 6 .

The side pressing wheel mechanism 6 includes a wheel mounting frame 601 that is rotatably connected to one end of the hinge frame 4, and the two ends of the wheel mounting frame 601 are respectively connected to a transmission wheel 602 in rotation. And the two transmission wheels 602 increase friction with the power cabinet through the anti-skid belt 603 .

The lateral extension distance of the two sets of hinge frames 4 is greater than that of the connecting frame 301 , and the spacing between the two sets of side pressing wheel mechanisms 6 is always greater than the spacing between the two sets of box fixing mechanisms 303 .

The backs of the box-corner bracket 302 and the wheel mounting bracket 601 are both provided with stay bolts 7 supported on the wall surface, and the length of the stay bolts 7 can be adjusted through threads.

Both sides of the sliding seat 2 are provided with sliding rails 201 to cooperate with the inner wall of the mounting seat 1 to slide up and down, and the bottom end of the sliding seat 2 is provided with a spring 202 for pressing and supporting the sliding seat 2 with the mounting seat 1 .

When in use, the back of the power cabinet to be tested is attached to the mounting base 1 and placed on the two corner brackets 302. When the operator gradually loosens the power cabinet, the weight of the power cabinet is supported by the two corner brackets 302. And the two box angle brackets 302 drive the sliding seat 2 to move down along the slide rails 201 on both sides through the two connecting frames 301. As the sliding seat 2 moves down, the spring 202 at the bottom end is compressed and the two sets of tension springs 5 at the top end are compressed. Being elongated, at this time, the two sets of tension springs 5 provide the inner downward pulling force to the two sets of hinge frames 4, thereby driving the side pressure wheel mechanisms 6 at the outer ends of the two sets of hinge frames 4 to move obliquely upward, and the two transmission wheels 602 will prevent anti-slip. Belt 603 is squeezed on the side of the power cabinet.

When the operator completely loosens the power cabinet, the weight of the power cabinet is completely borne by the bracket mechanism 3, so the bracket mechanism 3 will further drive the sliding seat 2 to move down, thereby driving the two sets of side pressing wheel mechanisms 6 to continue to tilt Moving upward, since the wheel mounting frame 601 is rotatably connected with the hinge frame 4, the two transmission wheels 602 of the side pressing wheel mechanism 6 can always tightly squeeze the side of the power cabinet, so that the placed power cabinet can be installed on the wall through the device , and with the installation of equipment in the power cabinet, the heavier the power cabinet, the less likely it will fall.

After confirming that the power cabinet will not fall, tighten the screws 3032 on the two sets of base plates 3031 so that the anti-skid plates 3033 at the inner ends of the screws 3032 are pressed against the side of the power cabinet, and finally put the corner bracket 302 and the wheel mounting bracket 601 behind The support rod bolts 7 are long enough to be in contact with the wall, which enhances the stability of the power cabinet after placement, further enhances the anti-drop effect of the power cabinet, and prevents the operator from shaking violently when installing equipment in the power cabinet.

After the current power cabinet test is completed, by loosening the two sets of screws 3032, the two sides of the power cabinet are no longer squeezed by the anti-skid plates 3033. At this time, the operator lifts the power cabinet a little so that the sliding seat 2 is in the spring. Under the action of 202, it is lifted a little. As the sliding seat 2 is lifted, the pulling force of the two sets of tension springs 5 to the hinge frame 4 is weakened. At this time, the side pressing wheel mechanism 6 will release the two sides of the power cabinet, so that the operator can Remove the power cabinet directly to facilitate the replacement of the next power cabinet for testing.

Although the present invention has been described in detail above with general description and specific embodiments, some modifications or improvements can be made on the basis of the present invention, which will be obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present invention fall within the scope of the claimed protection of the present invention.
