Description

Technical Field

[0001] This utility model relates to the field of low-voltage switchgear technology, and in particular to an anti-static low-voltage switchgear. Background Technology

[0002] Low-voltage switchgear, also known as control cabinet, is a set of switchgear, measuring instruments, protective electrical appliances and auxiliary equipment assembled in a closed or semi-closed metal cabinet or panel according to electrical wiring requirements. During normal operation, the circuit can be connected or disconnected by manual or automatic switches. In case of fault or abnormal operation, the circuit can be cut off or an alarm can be triggered by protective electrical appliances, and prompts or signals can be issued for deviations from normal operating conditions.

[0003] Traditional low-voltage switchgear involves assembling and fixing various electrical components onto an internal mounting plate, then connecting these components and threading cables through the plate to connect to external equipment. However, in practice, it has been found that the mounting positions of the internal mounting plates in typical low-voltage switchgear are fixed. This makes it difficult to fully utilize the internal space during component assembly, reducing the internal space utilization rate of the low-voltage switchgear. Consequently, this affects subsequent maintenance and repair, and diminishes the effectiveness and functionality of the low-voltage switchgear. Utility Model Content

[0004] This utility model addresses the problem that the assembly position of the placement plate inside a typical low-voltage switchgear is fixed, which makes it difficult to fully utilize the internal space of the switchgear during the assembly of electrical components, reducing the internal space utilization rate of the low-voltage switchgear, thus affecting subsequent maintenance and repair, and reducing the performance and functionality of the low-voltage switchgear. Therefore, an anti-static low-voltage switchgear is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A low-voltage cabinet for static electricity, comprising a cabinet body, a cabinet door hinged to the surface of the cabinet body, heat dissipation holes on both sides of the surface of the cabinet body, an adjustment device provided on the inner wall of the cabinet body, the adjustment device comprising two limiting rods, the two limiting rods being fixedly connected to the inner wall of the cabinet body, a plurality of evenly distributed placement plates being slidably connected to one side of the surfaces of the two limiting rods engaging with each other, an adjustment plate being fixedly connected to the inner wall of the cabinet body, a plurality of evenly distributed adjustment holes being opened on the surface of the adjustment plate, a screw being fixedly connected to the surface of each of the placement plates, a fixing rod being slidably connected through the arc surface of the screw, the fixing rod being inserted into the inner wall of the adjustment hole, the fixing rod being inserted into the inner wall of one side surface of the placement plate, and a nut being threadedly connected to the arc surface of the screw.

[0006] The effects achieved by the above components are: when the low-voltage cabinet body is in use, the internal space can be used more rationally, improving the space utilization rate, thereby better installing and fixing electrical components, and improving the use effect and functionality of the low-voltage cabinet body.

[0007] Preferably, an operating block is fixedly connected to the surface of the nut, and the surface of the operating block is provided with a plurality of anti-slip protrusions.

[0008] The effect achieved by the above components is that the operation block makes the nut more convenient and quick to use, thereby better fixing the position of the fixing rod and improving the ease of use of the nut.

[0009] Preferably, a spring is fixedly connected to one side surface of the fixing rod, and the other end of the spring is fixedly connected to the surface of the placement plate.

[0010] The effect achieved by the above components is that, through the setting of the spring, when the position adjustment nut is turned on the placement plate, the fixing rod can be quickly disengaged from the placement plate and the adjustment hole under the action of the spring force, thereby improving the efficiency of adjustment.

[0011] Preferably, a stabilizing rod is slidably connected through the surface of the fixing rod, and the stabilizing rod is fixedly connected to the surface of the placement plate.

[0012] The effect achieved by the above components is that, by setting up the stabilizing rod, the fixing rod can be kept stable during the sliding and pulling process, and is not easy to shake, so as to be inserted into the adjustment hole more accurately to fix the placement plate.

[0013] Preferably, a stop block is fixedly connected to the side surface of the screw away from the placement plate, and the specifications and dimensions of the stop block are adapted to the nut.

[0014] The effect achieved by the above components is that, by setting the stop, the nut can rotate stably on the screw, and it is not easy for the nut to loosen and fall off due to excessive rotation, which would affect the position adjustment and fixation of the placement plate.

[0015] Preferably, anti-static devices are provided on both sides of the surface of the low-voltage cabinet body at the location of the heat dissipation holes. The anti-static device includes a rotating shaft, which is fixedly connected to the surface of the low-voltage cabinet body. A connecting block is rotatably connected to the arc surface of the rotating shaft. A protective net is fixedly connected to one side surface of the connecting block. A bolt is inserted through one side surface of the protective net and is threadedly connected to the surface of the low-voltage cabinet body.

[0016] The effects achieved by the above components are as follows: when the low-voltage cabinet body is in use, it is less likely for excessive dust and impurities to enter the interior of the low-voltage cabinet body through the heat dissipation holes, reducing dust accumulation, thereby better protecting the internal circuit boards and other equipment, reducing the possibility of static electricity generation, and improving the safety of the low-voltage cabinet body in use.

[0017] Preferably, a reinforcing ring, which is a rubber ring, is fitted onto the arc surface of the bolt.

[0018] The effect achieved by the above-mentioned components is that, by setting up the reinforcing ring, the bolts are more stably and securely fitted when assembled on the protective net, thereby making the assembly of the protective net more stable and firm, and improving the stability of the protective net.

[0019] Preferably, a protective ring is fixedly connected to the surface of the protective net on the side closest to the low-voltage cabinet body.

[0020] The effect achieved by the above components is that, by adding a protective ring, the protective mesh is less likely to have gaps when it comes into contact with the surface of the low-voltage cabinet body, thus making it more difficult for dust to enter the interior of the low-voltage cabinet body and improving the effectiveness of the anti-static device.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] When in use, the low-voltage switchgear allows for more efficient use of internal space, improving space utilization and enabling better installation and fixation of electrical components, thus enhancing the effectiveness and functionality of the low-voltage switchgear.

Several evenly distributed placement plates 42 are slidably connected to one side of the surfaces of the two limiting rods 41 that are engaged with each other. An adjustment plate 43 is fixedly connected to the inner wall of the low-voltage cabinet body 1. Several evenly distributed adjustment holes 44 are opened on the surface of the adjustment plate 43. Screws 45 are fixedly connected to the surfaces of the placement plates 42 respectively. A fixing rod 46 is slidably connected through the arc surface of the screw 45. The fixing rod 46 is inserted into the inner wall of the adjustment hole 44 and into the inner wall of one side surface of the placement plate 42. A nut 47 is threaded onto the arc surface of the screw 45. When each… After the electrical components are assembled on the placement plates 42 inside the low-voltage cabinet body 1, the placement plates 42 are slid to slide inside the low-voltage cabinet body 1 until the spacing between adjacent placement plates 42 is appropriate. Then, the nut 47 on the screw 45 is rotated. Through the rotation of the nut 47, the fixing rod 46 slides on the screw 45 until the fixing rod 46 is inserted into the adjustment hole 44 on the surface of the adjustment plate 43, so that the fixing rod 46 is inserted into the surface of one side of the placement plate 42, ensuring that the position of the placement plate 42 is fixed. At this time, when the low-voltage cabinet body 1 is in use, the internal space can be used more rationally, improving the space utilization rate, thereby better installing and fixing electrical components, and improving the use effect and functionality of the low-voltage cabinet body 1.

[0030] Reference Figure 1 and Figure 2 as well as Figure 3As shown in the figure, this embodiment discloses that an operating block 48 is fixedly connected to the surface of the nut 47. The surface of the operating block 48 is provided with several anti-slip protrusions. The operation block 48 makes the nut 47 more convenient and quick to use, thereby better fixing the position of the fixing rod 46 and improving the ease of use of the nut 47. A spring 49 is fixedly connected to one side of the surface of the fixing rod 46, and the other end of the spring 49 is fixedly connected to the surface of the placement plate 42. The spring 49 allows the fixing rod 46 to quickly disengage from the placement plate 42 and the adjustment hole 44 under the elastic force of the spring 49 when the nut 47 is rotated to adjust the position of the placement plate 42, thereby improving the efficiency of adjustment.

[0031] Reference Figure 1 and Figure 2 as well as Figure 3 As shown, this embodiment discloses a stabilizing rod 410 that is slidably connected through the surface of the fixing rod 46. The stabilizing rod 410 is fixedly connected to the surface of the placement plate 42. By setting the stabilizing rod 410, the fixing rod 46 can be kept stable during the sliding and pulling process, and is not easy to shake. This allows it to be inserted into the adjustment hole 44 more accurately to fix the placement plate 42. A stop block 411 is fixedly connected to the side of the screw 45 away from the placement plate 42. The size of the stop block 411 is adapted to the nut 47. By setting the stop block 411, the nut 47 can rotate stably on the screw 45, and is not easy to loosen and fall off due to excessive rotation, which would affect the position adjustment and fixation of the placement plate 42.

[0032] Reference Figure 1 and Figure 4 As shown, this embodiment discloses an anti-static device 5 including a rotating shaft 51, which is fixedly connected to the surface of the low-voltage cabinet body 1. A connecting block 52 is rotatably connected to the arc surface of the rotating shaft 51. A protective net 53 is fixedly connected to one side surface of the connecting block 52. A bolt 54 is inserted through one side surface of the protective net 53 and threadedly connected to the surface of the low-voltage cabinet body 1. When adding protection to the low-voltage cabinet body 1, the protective net 53 is first rotated, causing the connecting block 52 fixedly connected to the protective net 53 to rotate on the arc surface of the rotating shaft 51 until the protection is applied. The mesh 53 contacts the surface of the low-voltage cabinet body 1, and the protective mesh 53 covers the surface of the heat dissipation hole 3. Then, the bolt 54 passes through the surface of the protective mesh 53, so that the bolt 54 is threadedly connected to the surface of the low-voltage cabinet body 1, ensuring the stable position of the protective mesh 53. At this time, when the low-voltage cabinet body 1 is in use, it is not easy for too much dust and impurities to enter the interior of the low-voltage cabinet body 1 from the heat dissipation hole 3, reducing the accumulation of dust, thereby better protecting the internal circuit boards and other equipment, reducing the possibility of static electricity generation, and improving the safety of the low-voltage cabinet body 1 in use.

[0033] Reference Figure 1 and Figure 4As shown in the figure, this embodiment discloses that a reinforcing ring 56 is fitted on the arc surface of the bolt 54. The reinforcing ring 56 is a rubber ring. By setting the reinforcing ring 56, the bolt 54 is more stably and closely fitted when assembled on the protective net 53, thereby making the assembly of the protective net 53 more stable and firm, and improving the stability of the protective net 53. A protective ring 55 is fixedly connected to the side surface of the protective net 53 near the low-voltage cabinet body 1. By setting the protective ring 55, it is not easy for gaps to be generated when the protective net 53 comes into contact with the surface of the low-voltage cabinet body 1, so that dust is less likely to enter the interior of the low-voltage cabinet body 1, thus improving the effectiveness of the anti-static device 5.

[0034] Working principle: After various electrical components are assembled on the placement plates 42 inside the low-voltage cabinet body 1, the placement plates 42 are slid to slide inside the low-voltage cabinet body 1 until the spacing between adjacent placement plates 42 is appropriate. Then, the operating block 48 on the surface of the nut 47 is rotated, causing the nut 47 on the screw 45 to rotate. Through the rotation of the nut 47, the fixing rod 46 slides on the screw 45 until the fixing rod 46 is inserted into the adjusting hole 44 on the surface of the adjusting plate 43, so that the fixing rod 46 is inserted into the surface of one side of the placement plate 42, ensuring that the position of the placement plate 42 is fixed. At this time, when the low-voltage cabinet body 1 is in use, the internal space can be used more rationally, improving the space utilization rate, thereby better installing and fixing electrical components, and improving the use effect and functionality of the low-voltage cabinet body 1.

[0035] When adding protection to the low-voltage cabinet body 1, first rotate the protective net 53 so that the connecting block 52 fixedly connected to the protective net 53 rotates on the arc surface of the rotating shaft 51 until the protective net 53 contacts the surface of the low-voltage cabinet body 1 and the protective net 53 covers the surface of the heat dissipation hole 3. Then, insert the bolt 54 through the surface of the protective net 53 so that the bolt 54 is threadedly connected to the surface of the low-voltage cabinet body 1, ensuring that the position of the protective net 53 is stable. At this time, when the low-voltage cabinet body 1 is in use, it is not easy for too much dust and impurities to enter the interior of the low-voltage cabinet body 1 from the heat dissipation hole 3, reducing the accumulation of dust, thereby better protecting the internal circuit boards and other equipment, reducing the possibility of static electricity generation, and improving the safety of the low-voltage cabinet body 1 in use.
