Technical Field
[0001] The utility model relates to the technical field of a switch cabinet which is convenient for maintenance and replacement, in particular to a low-voltage switch cabinet which is convenient for replacement. Background Art
[0002] The low-voltage switchgear is mainly used for switching control and protection of power transmission. There are many types of switchgear on the market. The most common one is the upright swing door cabinet structure, and there are also many pull-out cabinet structures. The pull-out cabinet structure has components installed in the drawer, so the components can be inspected by pulling out the drawer when needed.
[0003] According to the publication number "CN218161468U" of "A low-voltage withdrawable switch cabinet that is easy to replace and combine between boxes", it describes that "low-voltage switch cabinets are used in power plants and chemical, textile and other industries to transmit, distribute and convert electricity. There are pull-out and door-type low-voltage switch cabinets. Pull-out low-voltage switch cabinets often need to change the combination of boxes during use, so they have higher applicability." At the same time, it proposes that "although the existing pull-out switch cabinets can quickly change the combination of boxes, the combination is not stable enough, the cabinets are easy to fall off, and the internal pull-out cabinets do not have a fixed movement trajectory during use and are easy to get stuck during movement, so there are certain safety hazards."
[0004] The above technical solution "is provided with a connecting mechanism, since a first telescopic column is provided inside one end of the horizontal plate, a first spring is provided on the surface of the first telescopic column, and clamping blocks are fixedly connected to the two ends of the first telescopic column respectively, two clamping seats are symmetrically provided on both sides of the top of the first cabinet, a groove is provided inside the clamping seat, two telescopic shells are symmetrically provided inside the groove, a second telescopic column is provided inside the telescopic shell, a second spring is provided on the surface of the second telescopic column, and a hemispherical block is provided on the top of the second telescopic column, wherein when the horizontal plate enters the groove, as the horizontal plate is advanced, the clamping block squeezes the hemispherical block, and the clamping block is compressed under the action of the first telescopic column and the first spring, and the hemispherical block can Under the action of the second telescopic column and the second spring, the clamping block is compressed. As the cross plate is continuously pushed forward, after the clamping block is no longer in contact with the hemispherical block, the clamping block and the hemispherical block return to their original lengths. This can form sufficient resistance to ensure the stability of the combination between the boxes, and the cabinets are not easy to fall off during use. Then, through the setting of the movable mechanism, since two fixed blocks are symmetrically arranged on both sides of the pull-out cabinet, the opposite sides of the two fixed blocks are fixedly connected with a slider, the fixed block is slidably connected to the corresponding first slide groove, and the slider is slidably connected to the corresponding second slide groove. When the pull-out cabinet is in use, both sides of the pull-out cabinet are restricted by the slide groove at the same time, the movement trajectory is limited, and it is not easy to be stuck during movement, thereby improving the safety of the device.
[0005] Now the pull-out type focuses on the replacement between drawer boxes, but each drawer box contains different components. These components may need regular maintenance and replacement, but due to the depth of the drawer box, the replacement of components is not convenient. Because the drawer is in a horizontal state after being pulled out, the staff needs to raise their arms, and because of the depth of the drawer, they need to put their arms in for replacement, which can easily cause fatigue to the staff for a long time and affect the accuracy of maintenance. For this reason, a low-voltage switch cabinet that is easy to replace is designed. Utility Model Content

[0014] The utility model will be further described below in conjunction with the accompanying drawings.
[0015] Please refer to Figure 1-3 The utility model discloses a low-voltage switch cabinet which is easy to replace, comprising a box body 1, drawers 3 are detachably installed on the opposite side walls of the box body 1 through fixedly installed tracks 2, a drawer 3 is set between every two tracks 2, a positioning plate 6 is fixedly connected to the bottom side wall of each track 2, a follower plate 10 is rotatably connected to the bottom of the drawer 3 through a torsion spring, and the follower plate 10 corresponds to the positioning plate 6, a bottom side wall of the drawer 3 close to one end of the track 2 is provided with a bottom groove 11, a corner of one side of the bottom of the bottom groove 11 is rotatably connected to one end of the follower plate 10 through a torsion spring, and one end of the follower plate 10 away from the bottom groove 11 contacts the side wall of one end of the positioning plate 6, and an inner groove 7 is provided inside the drawer 3.
[0016] The drawer 3 is pulled out from the box body 1, and one end of the pulled out drawer 3 falls and tilts under the influence of gravity, so that the drawer 3 which was originally in a horizontal state is adjusted to a tilted state, thereby reducing the height of the drawer 3. To prevent the drawer 3 from escaping from the track 2 due to the tilt, a positioning plate 6 and a follower plate 10 are respectively provided at the bottom of the track 2 and the drawer 3. When the drawer 3 tilts and rotates, the follower plate 10 will be driven to move synchronously, so that one end of the follower plate 10 will contact and fit with one end of the positioning plate 6. The supporting force provided by the positioning plate 6 ensures the stability of the tilting of the drawer 3. To ensure the smooth movement of the drawer 3, after the device replacement is completed, the follower plate 10 is compressed into the bottom groove 11, and then the drawer 3 is pushed into the box body 1.
[0017] By lowering the state of the drawer 3 through the above-mentioned technical solution, the drawer 3 in the inclined state will not only be reduced in height, but also the internal state and devices of the drawer 3 can be better displayed to the staff due to the inclination, thereby improving the staff's replacement and maintenance of the devices.
[0018] Through holes 8 are evenly formed on the side wall of the drawer 3 at one end close to the track 2 , and side panels 9 are fixedly connected to the side walls of the drawer 3 at both sides away from each other and opposite to the track 2 .
[0019] Passing the wires through the through hole 8 can enable them to be stably connected to the devices installed in the inner groove 7. The side panels 9 provided can improve the stability of the connection between the drawer 3 and the track 2, ensuring that the drawer 3 can slide smoothly in the horizontal direction on the track 2.
[0020] A slide groove 4 is provided in the middle of the side wall opposite to the drawer 3, and a slide column 12 is slidably connected in the slide groove 4. The slide column 12 is fixedly connected to the side wall of one end of the drawer 3 through one end thereof. A mounting plate 5 is fixedly connected to one edge of the top side of the track 2, a through hole 8 is provided through the side wall at one end of the top of the track 2, a connecting groove 13 is provided through the side wall at one end of the track 2 close to the drawer 3, and the side panel 9 is telescopically and movably inserted in the connecting groove 13.
[0021] When the drawer 3 needs to be removed from the track 2, the drawer 3 is completely pulled out, and then the drawer 3 is lifted upward to move the slide post 12 out of the through hole 8, so that the drawer 3 is completely removed from the track 2. Because the connecting groove 13 is set up to ensure that the side panel 9 can move smoothly in the slide groove 4, the slide post 12 can ensure that the drawer 3 is still stably connected to the track 2 after the side panel 9 is completely pulled out from the slide groove 4, and the completely pulled out side panel 9 will not affect the rotation and tilting of the drawer 3. When the drawer 3 needs to remain in a horizontal state after being pulled out, the side panel 9 does not need to be completely pulled out.
