Description

Technical Field

[0001] The invention relates to the technical field of distribution boxes, in particular to a distribution box which is convenient for inspection and maintenance. Background Art

[0002] The distribution box plays a core role in the distribution of electric energy, including the main distribution box and the distribution box. Usually, the main distribution box and the distribution box are collectively referred to as the distribution box. In accordance with the requirements of electrical wiring, the distribution box assembles switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen. When in operation, it can effectively transmit the power of the power grid to various power terminals to meet different power needs. In addition, the distribution box also serves as a power collection and distribution center, rationally distributing the input power signal to the equipment that needs electricity, thereby achieving efficient distribution of energy. In order to ensure safety, the distribution box is also equipped with protective devices such as fuses, air switches and leakage protectors, which can be cut off in time when the current is abnormal to protect personal and equipment safety. The distribution box has the characteristics of small size, easy installation, special technical performance, fixed position, unique configuration function, no site restrictions, relatively common application, stable and reliable operation, high space utilization, small footprint and environmental protection effect.

[0003] At present, in conventional distribution boxes, the wires are directly connected to the distribution box equipment through screws. If the wires are replaced too frequently or the equipment is located in a dusty environment, it is very easy for the wiring terminals on the equipment to have poor contact due to dust, residues, and oxidation of the contact surface. The most common solution is to clean the contact surface, but most of the existing equipment and each wire are fixed separately by screws, which is very inconvenient to disassemble, resulting in inconvenient inspection and maintenance. Summary of the invention

[0016] The present invention has the following beneficial effects:

[0017] 1. In the distribution box which is convenient for inspection and maintenance, the wiring base fixed in the distribution box body can be located at the upper and lower sides of the air switch, and the base wiring groove fixed on the wiring base can be used to install the input wire and the output wire. When the hollow conductive sleeve fixed on the wiring base cooperates with the conductive rod on the movable seat, the conductive rod can slide in the hollow conductive sleeve when adjusting the position of the movable seat. When wiring, it is convenient to directly insert the conductive rod into the equipment wiring groove to connect the circuit, which greatly reduces the number of screws used and improves the convenience of disassembly and assembly. When inspecting and maintaining, the movable seat is close to the wiring base, which can cause the conductive rod to separate from the equipment wiring groove, and can directly and quickly disconnect the circuits of all air switches, greatly improving the safety performance in the subsequent maintenance process, and can conveniently clean the equipment wiring groove, which does not affect the replacement of the air switch and makes the cleaning and maintenance of the air switch more convenient. The two sets of clamping mechanisms set on the distribution box body can limit the adjustment position of the two adjustment plates, and when the circuit is connected, it can limit the position of the end of the conductive rod inserted into the equipment wiring groove.

[0018] 2. In the distribution box which is convenient for inspection and maintenance, when the circuit is connected, by adjusting the position of the movable seat, the movable seat can drive one end of the conductive rod and the two abutment blocks fixed at the end of the conductive rod to be inserted into the wiring slot of the equipment simultaneously. The movable seat can be limited by clamping the adjusting plate on the conical clamping block of the clamping mechanism. The threaded rod can be driven to rotate on the strip seat by the knob provided in the clamping mechanism, so that the conical clamping block drives the adjusting plate to move horizontally in the movable seat, so as to drive the rack in the first cavity to move horizontally. The gear fixed on the conductive rod meshes with the rack. When the locking cam is in place, the two springs are engaged and the locking cams are engaged, and when the locking cams are in place, the locking cams are engaged, and the locking cams are engaged, the locking cams are engaged, and the locking cams are engaged.

[0019] 3. In the distribution box which is convenient for inspection and maintenance, the sliding bracket is conveniently connected through a plurality of sliding grooves arranged on the wiring base. The sealing cover fixed on the sliding bracket can seal the opening of the base wiring slot during operation. At the same time, with the cooperation of the wire clamping groove opened on the sealing cover, the wires connected in the base wiring slot can be closely fitted to reduce the gap, so as to prevent dust from entering the base wiring slot during the use of the distribution box, thereby improving the dustproof effect and ensuring the stability of the circuit connection;

[0020] The sealing cover can be automatically opened and closed by utilizing the linkage between the wiring base and the movable seat. In the maintenance state, when the movable seat moves toward the wiring base, the movable seat conflicts with the interference frame during the movement, thereby driving the interference frame to move vertically in the second cavity in the wiring base, thereby achieving the purpose of conflicting with the second interference wedge fixed at one end of the interference frame. After the second interference wedge is interfered with, it drives the interference frame to move. The plurality of interference strips fixed on the interference frame can achieve the purpose of conflicting with the first interference wedge fixed on the sliding bracket during the movement, prompting the two sliding brackets to move away from each other, so that the two sealing covers arranged at the openings of the base wiring slot can be opened, which is convenient for adjusting the wires. When the movable seat is away from the wiring base, the sealing cover is closed to achieve a sealing effect to prevent dust from entering during the working process.

Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0031] For example, see Figures 1 to 8 A distribution box convenient for inspection and maintenance comprises a distribution box body 1, a wiring base 5 is fixed on both upper and lower sides of the distribution box body 1, a base wiring groove 6 for fixing a wire is arranged on the wiring base 5, a hollow conductive sleeve 7 is fixed on the wiring base 5, and the hollow conductive sleeve 7 is electrically connected to the base wiring groove 6;

[0033] A fixing seat 11 is fixed on both sides of the wiring base 5 , and a first threaded hole 12 is formed on the fixing seat 11 .

[0034] A clamping slot 14 is formed on the adjusting plate 10 , and the clamping mechanism comprises a conical clamping block 15 , which is matched with the clamping slot 14 .

[0035] When wiring, refer to Figure 1-Figure 6 , connect the input wire and the output wire to the base wiring groove 6 of the two wiring bases 5 respectively, install the air switch 3 on the slide rail 2 fixed on the distribution box 1, and the conductive rod 9 on the movable seat 8 can slide in the hollow conductive sleeve 7 of the wiring base 5 to form a retractable and adjustable conductive rod 9. Through the position of the movable seat 8, it is convenient to insert the conductive rod 9 into the equipment wiring groove 4 for circuit connection. The two sets of clamping mechanisms set on the distribution box 1 can limit the adjustment position of the two adjustment plates 10. When the circuit is connected, the position of the end of the conductive rod 9 inserted into the equipment wiring groove 4 can be accurately controlled. In the subsequent maintenance process of the air switch 3, when the conductive rod 9 is separated from the equipment wiring groove 4, all circuits of the air switch 3 can be directly disconnected, and the equipment wiring groove 4 can be conveniently cleaned, which does not affect the replacement of the air switch 3 and makes the cleaning and maintenance of the air switch 3 more convenient.

[0036] Through the fixing base 11 and the first threaded hole 12 opened on the fixing base 11, the wiring base 5 can be conveniently fixed in the distribution box 1 by using screws.

[0037] Through the card slot 14 opened on the adjustment plate 10, the adjustment plate 10 can be engaged with the conical card block 15 of the engagement mechanism during the downward movement of the movable seat 8. While limiting the movable seat 8, it is also convenient for the engagement mechanism to drive the adjustment plate 10 to move horizontally and smoothly during operation.

[0038] Embodiment 2: This embodiment is an improvement made on the basis of Embodiment 1. For details, please refer to Figures 1 to 8A first cavity 16 is provided in the movable seat 8, and a gear 17 and a rack 18 are respectively provided in the first cavity 16. The gear 17 is fixed on the conductive rod 9, and the rack 18 is fixedly connected to the adjusting plate 10. The gear 17 and the rack 18 are meshed with each other. A first spring 19 is provided in the first cavity 16, and the two ends of the first spring 19 are respectively connected to the movable seat 8 and the adjusting plate 10.

[0039] The locking mechanism also includes a strip seat 101, which is fixed on the distribution box 1, and a threaded rod 102 is rotatably connected to the strip seat 101, and the threaded rod 102 is threadedly connected to the conical block 15, and a knob 103 is fixed to one end of the threaded rod 102, and a second spring 104 is sleeved on the threaded rod 102, and the two ends of the second spring 104 are respectively against the knob 103 and the strip seat 101.

[0040] Two wedge-shaped conductive sheets 20 are arranged in the equipment wiring slot 4 , a third spring 21 is connected between the wedge-shaped conductive sheets 20 and the equipment wiring slot 4 , and two abutment blocks 22 are fixed to the end of the conductive rod 9 .

[0041] Two L-shaped blocks 23 are fixed at the opening of the equipment wiring slot 4 , and one side of the wedge-shaped conductive sheet 20 abuts against the L-shaped block 23 .

[0042] In the prior art, the conductive rod 9 can be inserted into the equipment wiring slot 4 of the air switch 3, but the simple insertion effect is not good and the conductive contact effect is poor. Figure 1-Figure 6 When the circuit is connected, by adjusting the position of the movable seat 8, the movable seat 8 can drive the conductive rod 9 and the two abutment blocks 22 fixed at the ends of the conductive rod 9 to be inserted into the equipment wiring slot 4. At the same time, the adjusting plate 10 is clamped on the conical clamping block 15 of the clamping mechanism to limit the movable seat 8. The knob 103 set in the clamping mechanism can drive the threaded rod 102 to rotate on the strip seat 101, so that the conical clamping block 15 drives the adjusting plate 10 to move horizontally in the movable seat 8. The first spring 19 accumulates force, which can achieve the purpose of driving the rack 18 in the first cavity 16 to move horizontally, and the conductive rod 9 can drive the two abutment blocks 22 to rotate in the equipment wiring slot 4, so that the abutment blocks 22 and the two wedge-shaped conductive sheets 20 are in conflict. The third spring 21 accumulates force, and the elastic force of the third spring 21 makes the wedge-shaped conductive sheet 20 and the conductive rod 9 come into close contact, thereby improving the contact effect and the stability of the conductive rod 9 in the equipment wiring slot 4, so that the circuit is relatively stable when flowing.

[0043] By setting the second spring 104, its own elastic force can act on the knob 103 and the strip seat 101 during the operation to firmly press them together, thereby preventing the knob 103 from loosening after the operation is completed, thereby affecting the contact effect between the contact block 22 and the two wedge-shaped conductive sheets 20.

[0044] The two L-shaped blocks 23 fixed at the opening of the equipment wiring slot 4 can prevent dust from entering one side of the equipment wiring slot 4 and affecting the movement of the wedge-shaped conductive sheet 20. On the other hand, they can limit the position of the wedge-shaped conductive sheet 20 to prevent the two wedge-shaped conductive sheets 20 from approaching each other and affecting the resistance block 22 from entering the equipment wiring slot 4.

[0045] Embodiment 3: This embodiment is an improvement made on the basis of Embodiment 1. For details, please refer to Figures 1 to 8 A second cavity 24 is provided on the wiring base 5, and a plurality of slide grooves 25 are provided on the wiring base 5, a sliding bracket 26 is slidably connected to the slide groove 25, and the sliding bracket 26 is elastically connected to the wiring base 5 through a fourth spring 27, and two sealing covers 28 are provided at the opening of the base wiring groove 6, and the sealing cover 28 is fixedly connected to the sliding bracket 26, and a wire clamping groove 29 is provided on the sealing cover 28.

[0046] An abutment frame 30 is disposed in the second cavity 24 . The abutment frame 30 is elastically connected to the wiring base 5 via a fifth spring 31 . A plurality of abutment bars 32 are fixed on the abutment frame 30 . A first abutment wedge 33 is fixed on the sliding bracket 26 .

[0047] A resisting rod 34 is slidably connected to the wiring base 5 , a sixth spring 35 is connected between the resisting rod 34 and the wiring base 5 , a second resisting wedge 13 is fixed to one end of the resisting frame 30 , and one end of the resisting rod 34 resists the second resisting wedge 13 .

[0048] In the prior art, the base wiring slot 6 of the wiring base 5 is open. If the working environment of the distribution box 1 is relatively bad, for example, there is a lot of dust in the environment, dust will enter the base wiring slot 6, thereby affecting the fixing effect and contact effect of the wire. Figure 2-Figure 7 , through the plurality of slide grooves 25 provided on the wiring base 5, the sliding bracket 26 can be connected, and through the cooperation of the fourth spring 27, the sealing cover 28 fixed on the sliding bracket 26 can achieve the effect of sealing the opening of the base wiring slot 6, and at the same time, the wire clamping groove 29 provided on the sealing cover 28 can be closely fitted to the wire connected in the base wiring slot 6, which can prevent dust from entering the base wiring slot 6 during the use of the distribution box 1, improve the dustproof effect, and ensure the stability of the circuit connection;

[0049] In the maintenance state, the knob 103 rotates in the other direction, prompting the threaded rod 102 to drive the conical block 15 to reset, and the conical block 15 drives the adjustment plate 10 to move horizontally to reset, so that the rack 18 drives the gear 17 to rotate, prompting the conductive rod 9 to rotate and reset, and at the same time, the two abutment blocks 22 fixed on the conductive rod 9 contact and abut against the wedge-shaped conductive sheet 20 after rotation, and by pushing the movable seat 8 to move vertically, the conductive rod 9 is separated from the equipment wiring slot 4, so as to directly disconnect the circuits of all air switches 3, and at the same time, the movable seat 8 abuts against the abutment frame 30 during the movement, thereby driving the abutment frame 30 to move in the second wiring base 5. The sixth spring 35 connected between the contact rod 34 and the wiring base 5 accumulates force. After the second contact wedge 13 is interfered with, it drives the contact frame 30 to move. At the same time, the fifth spring 31 accumulates force. The plurality of contact strips 32 fixed on the contact frame 30 can interfere with the first contact wedge 33 fixed on the sliding bracket 26 during the movement, so that the two sliding brackets 26 move away from each other. The fourth spring 27 accumulates force, so that the two sealing covers 28 arranged at the opening of the base wiring slot 6 can be opened, which is convenient for adjusting the wires.

[0050] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0051] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
