Description

Technical Field

[0001] The utility model relates to the technical field of switch cabinets, in particular to a low-voltage complete switch cabinet which is convenient to maintain. Background Art

[0002] The main function of the switchgear is to open and close, control and protect electrical equipment in the process of power generation, transmission, distribution and power conversion in the power system. The components in the switchgear mainly include circuit breakers, disconnectors, load switches, operating mechanisms, mutual inductors and various protective devices. There are many ways to classify switchgear. According to the voltage level, it can be divided into high-voltage switchgear and low-voltage switchgear. It is mainly suitable for various occasions such as power plants, substations, petrochemicals, metallurgy and steel rolling, light industry and textiles, factories and mines, residential areas, high-rise buildings, etc.

[0003] For example, the patent with announcement number CN214100355U discloses a low-voltage switch cabinet that is easy to maintain, including a cabinet body, a cabinet door is installed on the side wall of the cabinet body, and a controller is fixed to the top inner end of the cabinet body, both sides of the cabinet body are provided with card slots, and the interior of the cabinet body is connected to a mounting plate near the bottom of the card slot, both ends of the mounting plate are provided with slide grooves, and a slide bar matching the slide groove is fixed on the side of the inner wall of the cabinet body near the mounting plate, side panels are installed inside the card slots, pull handles are fixed at both ends of the outer sides of the side panels, and limiting holes are provided at the ends of the side panels.

[0004] Through the above arrangement, the utility model described in the prior art can pull the side panels out of the slots by cooperating with the fixing knobs, limiting holes, pull handles, and side panels, thereby exposing both sides of the mounting plate. This makes it easier for workers to perform maintenance from both sides of the mounting plate, which is simple and convenient to operate, expands the maintenance space, reduces the difficulty coefficient, and greatly improves work efficiency. However, the low-voltage switchgear for easy maintenance of the prior art solution has the following defects during operation:

[0005] When the above device is in use, when it is necessary to pull the mounting plate outward to repair the electronic components inside the switch cabinet, the motors are started at the same time, and the gears are used to drive the racks to pull the mounting plate outward. The provision of multiple motors increases the manufacturing cost of the device, and the device does not have a function of limiting the mounting plate. When the mounting plate is pulled out for repair, the staff slightly pushes the mounting plate, and the mounting plate will be retracted into the interior of the cabinet, which is not conducive to the smooth progress of the repair work. Utility Model Content

[0006] The utility model aims to provide a low-voltage complete switch cabinet which is easy to maintain, and is mainly used to solve the technical problem in the prior art that the mounting plate has no position limiting function.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0008] A low-voltage complete switch cabinet that is easy to maintain includes a cabinet body and a protective door. The inner side wall of the cabinet body is symmetrically provided with a slide groove, and the inner side wall of the slide groove is slidably connected to a pull-out plate. The inner side wall of the cabinet body is located on the top of the pull-out plate and is fixedly connected to a fixed plate. The bottom of the fixed plate is slidably connected to the top of the pull-out plate. The inner side wall of the cabinet body is symmetrically slidably connected to a fixed block, and a limiting component is provided on the top of the fixed block. The bottom of the pull-out plate is symmetrically fixedly connected to a second mounting seat, and the inner side wall of the second mounting seat is rotatably connected to a support assembly.

[0009] The working principle and beneficial effects of this utility model:

[0010] 1. Working principle: When the device needs to be repaired, it is only necessary to adjust the limit assembly first. The pull-out plate is not restricted. At this time, the pull-out plate can be pulled outward to slide outward along the inner wall of the slide groove, thereby moving the electronic components that need to be repaired to the outside of the cabinet. In the process of pulling the pull-out plate outward, the support assembly works, and then the pull-out plate is supported by the support assembly.

[0011] 2.Beneficial effects:

[0012] The existing technology can pull the side panels out of the slots by setting up fixed knobs, limiting holes, pull handles and side panels, thereby exposing both sides of the mounting panel, making it easier for staff to perform maintenance from both sides of the mounting panel. However, the existing technology has the technical problem of not having a limiting function for the mounting panel. The present solution can quickly limit the pull-out panel by setting a limiting component, thereby preventing the pull-out panel from re-entering the cabinet due to external thrust when repairing electronic components inside the cabinet. The support component is set up, so that when the pull-out panel is pulled out, the support component can support the pull-out panel, thereby increasing the technical problem of the stability of the device.

[0013] When the cam is fully pulled out, the adjusting rod is released and the adjusting rod is automatically engaged with the inner part of another limiting hole under the action of stretching the first spring, thereby realizing the lowering operation of the pull-out plate and preventing the pull-out plate from automatically retracting into the inner part of the cabinet during maintenance.

[0014] Preferably: the top of the adjusting rod is rotatably connected to a card block, and a rectangular groove is opened on the inner wall of the cabinet, and the height of the rectangular groove is slightly greater than the height of the card block. When the adjusting rod is pulled upward, the adjusting rod disengages from the limit hole, and the card block is rotated ninety degrees at this time, and the end of the card block is stuck into the inside of the rectangular groove, and then the pull-out plate is pulled to prevent the adjusting rod from resetting under the action of the stretched first spring during the process of pulling the pull-out plate.

[0015] Preferably: the side wall of the pull-out plate is rotatably connected with a plurality of balls, and the plurality of balls are rollingly connected with the inner wall of the slide groove. The arrangement of the plurality of balls reduces the friction between the pull-out plate and the slide groove, making it easier to pull the pull-out plate outward.

[0016] Preferably: the support assembly includes a sleeve rod rotatably connected to the inner wall of the second mounting seat, the outer wall of the sleeve rod is slidably connected to the sleeve, the outer wall of the sleeve end is rotatably connected to the first mounting seat, and the bottom of the first mounting seat is fixedly connected to the top of the fixed plate. In the process of pulling the pull-out plate outward, the second mounting seat drives the sleeve rod to slide outward along the inner wall of the sleeve, and as the pull-out plate is pulled outward, the end of the sleeve rotates between the first mounting seat. When the pull-out plate is fully pulled out, the pull-out plate is supported by the cooperation between the sleeve and the sleeve rod, thereby increasing the technical problem of the stability of the device.

[0017] Preferably: a pull rod passes through and is slidably connected to the side wall of the sleeve, and a second spring is sleeved on the outer side wall of the pull rod, one end of the second spring is fixedly connected to the end of the pull rod, and the other end of the second spring is fixedly connected to the outer side wall of the sleeve. When the sleeve rod moves upward along the inner side wall of the sleeve, the end of the pull rod slides with the outer side wall of the sleeve. As the sleeve rod moves upward along the inner side wall of the sleeve, when the pull rod is no longer in contact with the sleeve rod, the pull rod automatically enters the interior of the sleeve under the action of the stretched second spring, thereby preventing the sleeve rod from retracting into the interior of the sleeve during maintenance of the cabinet.

[0018] Preferably, the length of the sleeve is much greater than the telescopic length of the sleeve rod, so as to prevent the sleeve rod from being separated from the sleeve. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figure 1-5As shown, a low-voltage complete switch cabinet that is easy to maintain includes a cabinet body 1 and a protective door 2. The inner wall of the cabinet body 1 is symmetrically provided with a slide groove 7. The inner wall of the slide groove 7 is slidably connected to a pull-out plate 3. The inner wall of the cabinet body 1 is located on the top of the pull-out plate 3 and is fixedly connected to a fixed plate 10. The bottom of the fixed plate 10 is slidably connected to the top of the pull-out plate 3. The inner wall of the cabinet body 1 is symmetrically slidably connected to a fixed block 14. A limit assembly is provided on the top of the fixed block 14. The limit assembly includes an adjustment rod that passes through and is fixedly connected to the top of the fixed block 14. 6. A plurality of limiting holes 15 are provided on the top of the pull-out plate 3, and the limiting holes 15 are adapted to the adjusting rod 6. The outer wall of the adjusting rod 6 is provided with a first spring 12. The top of the first spring 12 is fixedly connected to the bottom of the fixing block 14. The bottom of the first spring 12 is fixedly connected to the top of the fixing plate 10. When it is necessary to repair the electronic components inside the cabinet 1, the adjusting rod 6 is first pulled upward, and the fixing block 14 is slid upward along the inner wall of the cabinet 1 through the adjusting rod 6. In this process, the first spring 12 is stretched, and the first spring 12 is stretched. As the adjusting rod 6 moves upward, the adjusting rod 6 will disengage from the limiting hole 15. At this time, the block 13 is rotated ninety degrees, and the end of the block 13 is stuck into the inside of the rectangular groove 5. Then, the pull-out plate 3 is pulled to slide outward along the inner wall of the slide groove 7. The bottom of the pull-out plate 3 is symmetrically fixedly connected to the second mounting seat 18. The inner side wall of the second mounting seat 18 is rotatably connected to the support assembly. The support assembly includes a sleeve rod 8 rotatably connected to the inner side wall of the second mounting seat 18, and the outer side wall of the sleeve rod 8 is slidably connected to the sleeve 4. The outer side wall of the end of the sleeve 4 is rotatably connected to the first mounting seat 9, and the bottom of the first mounting seat 9 is fixedly connected to the top of the fixed plate 10. In the process of pulling the pull-out plate 3 outward, the second mounting seat 18 drives the sleeve rod 8 to slide outward along the inner side wall of the sleeve 4. As the pull-out plate 3 is pulled outward, the end of the sleeve 4 rotates with the first mounting seat 9. When the pull-out plate 3 is fully pulled out, the pull-out plate 3 is supported by the cooperation between the sleeve 4 and the sleeve rod 8, thereby increasing the technical problem of the stability of the device.

[0027] From the above, it can be seen that the specific implementation of the present utility model is as follows:

[0028] When it is necessary to repair the electronic components inside the cabinet 1, first pull the adjusting rod 6 upwards, and the adjusting rod 6 will make the fixing block 14 slide upwards along the inner wall of the cabinet 1. During this process, the first spring 12 is stretched, and as the adjusting rod 6 moves upward, the adjusting rod 6 will disengage from the limiting hole 15. At this time, the block 13 is rotated ninety degrees, and the end of the block 13 is stuck in the inside of the rectangular groove 5, and then the pull-out plate 3 is pulled again to make the pull-out plate 3 slide outward along the inner wall of the slide groove 7. In the process of pulling the pull-out plate 3 outwards, the second mounting seat 18 drives the sleeve rod 8 to slide outwards along the inner wall of the sleeve 4. As the pull-out plate 3 is pulled outwards, the end of the sleeve 8 rotates between the first mounting seat 9. When the pull-out plate 3 is fully pulled out, the sleeve 4 and the sleeve rod 8 cooperate to pull the pull-out plate 3 out. The pull plate 3 plays a supporting role, thereby increasing the technical problem of the stability of the device. When the sleeve rod 8 moves upward along the inner wall of the sleeve 4, the end of the pull rod 11 slides with the outer wall of the sleeve rod 4. As the sleeve rod 8 moves upward along the inner wall of the sleeve 4, when the pull rod 11 is no longer in contact with the sleeve rod 8, the pull rod 11 automatically enters the interior of the sleeve 4 under the action of the stretched second spring 17, thereby preventing the sleeve rod 8 from retracting into the interior of the sleeve 4 during the maintenance of the cabinet 1. Finally, the block 13 is rotated in the opposite direction to disengage the block 13 from the rectangular groove 5. Under the action of the stretched first spring 12, the adjusting rod 6 automatically snaps into the inside of another limiting hole 15, thereby realizing the lowering operation of the pull plate 3 and preventing the pull plate 3 from automatically retracting into the interior of the cabinet 1 during the maintenance process.

[0029] The above is only an embodiment of the present invention, and the commonly known specific structures and characteristics of the scheme are not described in detail here. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, and these should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection claimed by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
