Description

Technical Field

[0001] This invention relates to the field of power equipment, and in particular to a power box for power engineering. Background Technology

[0002] Electrical boxes are primarily used for distributing electrical energy. They serve as a control center for the rational allocation of power across power lines and provide a direct view of the operating status of power supply circuits. Commonly found in outdoor public spaces, electrical boxes typically house numerous electrical devices, such as meters and switches. These devices connect to the outside via cables. To facilitate this connection, existing electrical boxes often have cable routing holes. However, the number of electrical devices and cables used varies within the box. Sometimes, a cable can be connected to the outside through just one cable routing hole, leaving the other unused. This can result in a large opening in the unused cable routing hole, or a large opening with a small total cable diameter. Consequently, dust can easily enter the electrical box through the unused cable routing hole or the remaining opening, leading to dust accumulation and affecting the operation of the electrical equipment.

Detailed Implementation

[0013] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0014] A power box for power engineering includes a box body 1, a base 2 is provided at the middle of the bottom of the box body 1, a bottom plate 3 is provided at the bottom of the base 2, a circular mounting hole 4 is provided on the bottom wall of the box body 1 on the outer side of the base 2, a line-in mechanism 5 is provided on the bottom plate 3 extending into the mounting hole 4, and an anti-theft mechanism 6 is provided inside the box body 1 and is movably connected to the line-in mechanism 5. The cable inlet mechanism 5 includes a fixed base 51 located on top of the base plate 3. A movable cavity 52 is provided within the fixed base 51. A top plate 53 and a support plate 54 are arranged sequentially from top to bottom within the movable cavity 52. ​​A spring 155 is provided at the bottom of the support plate 54. A vertical tube 56 extending into a corresponding mounting hole 4 is provided at the top of the top plate 53. Several slots 57 are radially arranged on the top surface of the side wall of the vertical tube 56. A locking block 58 embedded in one set of slots 57 is provided at the top surface of the side wall of the mounting hole 4. The vertical tube 56 has an inlet pipe 59 radially arranged on its outer wall, which communicates with its interior. The vertical tube 56 has a circular tube 510 that seals the opening of the inlet pipe 59 inside. The top of the side wall of the circular tube 510 has an inlet port 511 corresponding to the opening of the inlet pipe 59. The circular tube 510 below the inlet port 511 has a filling seat 512 inside. The bottom of the filling seat 512 has a groove 513. The groove 513 has a telescopic rod 514 and a spring II 515 connected to the top plate 53 inside.

[0015] The anti-theft mechanism 6 includes a ring of grooves 61 surrounding the inner wall of the vertical tube 56. A positioning groove 62 corresponding to a slot 57 is axially provided on the inner wall of the vertical tube 56 at the bottom of the groove 61. The top of the positioning groove 62 communicates with the bottom of the groove 61. A boss 63 is provided at the bottom of the housing 1. A T-shaped slide rod 64 is slidably mounted on the boss 63. A spring III 65 is sleeved on the slide rod 64 on the back of the boss 63. An L-shaped rod 66 extending into the vertical tube 56 is provided at the end of the slide rod 64. The end of the L-shaped rod 66 extends into one of the positioning grooves 62. The grooves 61 and positioning grooves 62 are located on the inner wall of the vertical tube 56 between the slot 57 and the round tube 510. The number of positioning grooves 62 is equal to the number of slots 57. The diameter of the horizontal end of the L-shaped rod 66 is adapted to the opening width of the positioning groove 62.

[0016] The filling seat 512 is integrally formed with the round tube 510. The size of the round tube 510 is adapted to the inner diameter of the vertical tube 56. A one-way air inlet pipe 7 is provided at the bottom of the side wall of the round tube 510 below the filling seat 512, located above the fixed seat 51. A one-way air outlet pipe 8 is provided at the top of the groove 513, extending to the top of the filling seat 512.

[0017] like Figure 2 As shown, the fixing seat 51 has a rectangular structure, and the top of the base plate 3 is provided with a rectangular fixing groove 9 to accommodate the bottom end of the fixing seat 51.

[0018] like Figure 2 As shown, the top of the fixed base 51 is provided with a circular hole that communicates with the movable cavity 52 and is adapted to the size of the vertical tube 56. The vertical tube 56 passes through the circular hole and is fixedly connected to the top plate 53. The bottom end surface of the top plate 53 is provided with several receiving grooves with a cross section of an arc. The receiving grooves are provided with ball bearings 10 that extend to the outside and abut against the top surface of the support plate 54.

[0019] During installation, the vertical tube 56 is pressed downwards to compress the spring I55 via the top plate 53 and the support plate 54, causing it to contract within the movable cavity 52. ​​This changes the height of the top of the vertical tube 56. Next, the fixing seat 51 is placed into the fixing groove 9 for horizontal fixation. At this point, the vertical tube 56 is aligned with the mounting hole 4. After releasing the vertical tube 56, the spring I55's extension force pushes the support plate 54 and the top plate 53 to insert the top of the vertical tube 56 into the mounting hole 4. During this process, the vertical tube 56 is rotated for fine-tuning so that one set of slots 57 aligns with the locking block 58. Finally, one set of slots 57 at the top of the vertical tube 56 is engaged with the locking block 58. The locking block 58 then holds the top of the vertical tube 56 in place, and the fixing groove 9 engages. The fixed base 51 is used to prevent the cable inlet mechanism 5 from moving up, down, or horizontally. At the same time, the locking block 58 locks the slot 57 to prevent the vertical tube 56 from rotating and affecting the orientation of the cable inlet tube 59. Before installing the vertical tube 56, the L-shaped rod 66 needs to be pulled and the sliding rod 64 needs to slide in the sliding hole on the boss 63. At the same time, the vertical end of the sliding rod 64 compresses the spring III 65, thereby changing the position of the L-shaped rod 66 so that it is located directly above the opening of the vertical tube 56 to prevent it from affecting the installation of the vertical tube 56. After the vertical tube 56 is installed, the L-shaped rod 66 is released. Under the push of the spring III 65, the horizontal end of the L-shaped rod 66 will finally be embedded in one of the positioning slots 62.

[0020] like Figure 3 The extended spring II 515 and telescopic rod 514 can pull the filling seat 512 and the round tube 510, thereby limiting the upward movement of the round tube 510. At the same time, the upward-moving round tube 510 will offset the inlet port 511 from the opening of the inlet pipe 59, thereby sealing the opening of the inlet pipe 59. So when the inlet pipe 59 is in an idle state, no foreign objects will enter the round tube 510 through the inlet pipe 59 and the inlet port 511 and eventually flow into the box 1.

[0021] When it is necessary to introduce a wire into the housing 1 through the inlet pipe 59, the round pipe 510 is pressed downwards and the spring II 515 and the telescopic rod 514 are compressed, causing the inlet port 511 to move down and connect with the opening of the inlet pipe 59. At this time, the wire can be introduced into the housing 1 and connected to the equipment through the inlet pipe 59, the inlet port 511, the opening of the round pipe 510 and the opening of the vertical pipe 56. At the same time, when the amount of wire introduced is small, after the round pipe 510 is released, it is driven to move upwards by the stretching force of the spring II 515, which in turn drives the inlet port 511 and the wire passing through the inlet port 511 to move upwards, so as to lock the wire in the upper half of the opening of the inlet pipe 59, thereby changing the size of the connection opening between the inlet port 511 and the inlet pipe 59, so as to prevent foreign objects from entering the round pipe 510 through the inlet port 511 and eventually flowing into the housing 1. During the above process, when the circular tube 510 and the filling seat 512 move upward in the vertical tube 56, they act as a piston, thereby drawing external gas into the vertical tube 56 below the filling seat 512 through the one-way air inlet pipe 7 for storage. When the circular tube 510 and the filling seat 512 are squeezed downward, the gas in the vertical tube 56 below the filling seat 512 is squeezed out through the groove 513 and the one-way air outlet pipe 8 to the circular tube 510 and the vertical tube 56 above the filling seat 512, so as to play a gas cleaning role on the inside of the two.

[0022] When the orientation of the inlet pipe 59 needs to be adjusted, simply press the vertical pipe 56 downwards to compress the spring 155 via the top plate 53 and the support plate 54. This causes the vertical pipe 56 to move the slot 57 downwards and separate from the block 58. Simultaneously, the positioning groove 62 at the top of the vertical pipe 56 slides downwards on the L-shaped rod 66, eventually causing the slide groove 61 to slide to the horizontal end of the L-shaped rod 66. At this point, the orientation of the inlet pipe 59 can be changed by rotating the vertical pipe 56, causing the ball bearing 10 on the top plate 53 to rotate on the support plate 54. The slide groove 61 on the vertical pipe 56 slides on the horizontal end of the L-shaped rod 66. This allows the orientation of the inlet pipe 59 to be changed to meet production requirements. After the orientation of tube 59 is adjusted and a slot 57 on vertical tube 56 is aligned with a block 58, vertical tube 56 is released. Driven by the stretching force of spring I55, vertical tube 56 moves upward and causes one set of slots 57 to engage with block 58. Since the positioning slots 62 and slots 57 are set one-to-one, when one set of slots 57 is aligned with block 58, the horizontal end of L-shaped rod 66 in slide groove 61 also corresponds to one set of positioning slots 62. Therefore, the upward-moving vertical tube 56 can cause one set of positioning slots 62 to engage with the horizontal end of L-shaped rod 66, thus ensuring that the anti-theft mechanism 6 does not affect the rotation of vertical tube 56 and inlet tube 59.

[0023] When an outsider operates the inlet mechanism 5, if they press down on the vertical tube 56 to change its height and pull it out from the mounting hole 4, the L-shaped rod 66 hooks onto the top wall of the slide groove 61 to prevent the top of the vertical tube 56 from being pulled out from the mounting hole 4. During this process, the mounting hole 4 abuts against the top of the vertical tube 56, and the fixing groove 9 fixes the fixing seat 51. At this time, the inlet mechanism 5 cannot be removed smoothly. Only when a professional worker opens the power box with a key and operates the anti-theft mechanism 6, allowing the L-shaped rod 66 to be pulled out from the positioning groove 62 or the slide groove 61, can people move the vertical tube 56 down and pull it out from the mounting hole 4, thereby removing the inlet mechanism 5. In this way, the inlet mechanism 5 achieves the purpose of anti-theft. At the same time, the movable connection between the inlet mechanism 5 and the box 1 also facilitates its disassembly for replacement or maintenance.

[0024] The present invention has been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
