Description

Technical Field

[0001] This utility model relates to the field of distribution box manufacturing, and in particular to a distribution box that is easy to maintain. Background Technology

[0002] According to the patent document with announcement number CN221928941U, the side plate is fixed inside the support column by fixing the mounting plate with the meter device to the fixed column. Then, the side plate is fixed inside the support column by the continuous action of the connecting block, pin, and first spring, thereby completing the sealing of both sides of the distribution box. Then, the sliding rod is inserted into the railing, and the sliding rod is locked by pressing the button upward to make the limit plate move up along the guide rod synchronously. This fixes the rainproof top above the railing.

[0003] The patent document describes a method for assembling a distribution box using four pillars to form the frame. Side panels are then inserted into both sides of the frame, and a rainproof roof is fixed to the top to complete the assembly process. This assembly process is relatively cumbersome. Furthermore, the first two pillars, located at the front of the distribution box and within the maintenance personnel's work area, pose a risk of bumping or knocking when replacing electrical components. Additionally, the side panels need to be removed and reinstalled during maintenance, which is inconvenient and hinders quick installation. Utility Model Content

[0004] The purpose of this utility model is to provide a power distribution box that is easy to maintain in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A power distribution box that is easy to maintain includes a support mechanism, protective mechanisms on both sides of the support mechanism, and a locking mechanism on the front of the support mechanism.

[0007] The support mechanism includes a quilt frame, a top frame fixed to the upper end of the quilt frame, and a bottom frame fixed to the lower end of the quilt frame. The top frame, quilt frame, and bottom frame form a C-shaped frame, and an mounting bracket is fixed to the front side of the quilt frame.

[0008] The protective mechanism includes side panels, with side strips on the front of the side panels and the rear of the side panels hinged to the side of the frame. Each side strip has two through-holes.

[0009] The locking mechanism includes a locking frame, the lower end of which is hinged to the front end of the base frame. Two locking hooks are slidably connected at the rear end of the locking frame at the position of the side strip, and a push spring is fixed at the lower end of each locking hook. A connecting rod is fixed between the two locking hooks on the same side of the locking frame.

[0010] Preferably, a T-shaped groove is provided at the rear end of the locking frame at the position of the locking hook, and the two T-shaped grooves on the same side of the locking frame are connected by a through hole.

[0011] Preferably, each locking hook has a T-shaped slider fixed at its front end for sliding within a T-shaped groove, and the connecting rod is slidably connected within the perforation.

[0012] Preferably, a door panel is hinged to the front side of the locking frame, and a door lock is fixed to the door panel at a position away from the door hinge.

[0013] Preferably, the rear side of the locking frame is detachably connected to two pull ropes, and the other ends of the two pull ropes are fixed to the two sides of the top of the base frame.

[0032] The present invention will be further described below with reference to the accompanying drawings:

[0033] like Figures 1-11As shown, a power distribution box that is easy to maintain includes a support mechanism 1, protective mechanisms 2 on both sides of the support mechanism 1, and a locking mechanism 3 on the front side of the support mechanism 1.

[0034] In this embodiment: the support mechanism 1 includes a frame 12, a top frame 11 is fixed to the upper end of the frame 12, and a bottom frame 13 is fixed to the lower end of the frame 12. The top frame 11, the frame 12 and the bottom frame 13 form a C-shaped frame. A mounting frame 14 is fixed to the front side of the frame 12. The frame 12 is used to support the mounting frame 14. At the same time, the mounting frame 14 is used to install the corresponding electricity meter device. The top frame 11 and the bottom frame 13 are used to enclose the top and bottom of the entire distribution box.

[0035] In this embodiment: the protective mechanism 2 includes a side plate 21, a side strip 22 on the front side of the side plate 21, and the rear end of the side plate 21 is hinged to the side of the frame 12. Each side strip 22 has two through-holes 23. A square hole for heat dissipation and ventilation is provided on the upper side of the side plate 21. A cooling fan 24 is fixed on the inner side of the side plate 21 at the square hole position, and a grid plate is fixed on the outer side of the side plate 21 at the square hole position. A filter screen is provided in the grid plate on the outer side of the side plate 21. The side plates 21 on both sides of the frame 12 are used to seal the two sides of the entire distribution box. At the same time, the cooling fan 24 is used to ventilate the entire distribution box, thereby reducing the temperature inside the distribution box. In addition, when it is necessary to repair the internal meter components of the distribution box, the side strip 22 is released from the lock by flipping the locking mechanism 3. Then, the side plate 21 is flipped outward to open the two sides of the entire distribution box, thereby expanding the operating space when maintaining the distribution box.

[0036] In this embodiment: the locking mechanism 3 includes a locking frame 31, the lower end of which is hinged to the front end of the base frame 13. Two locking hooks 32 are slidably connected at the rear end of the locking frame 31 at the position of the side strip 22, and a push spring 34 is fixed to the lower end of each locking hook 32. A connecting rod 33 is fixed between the two locking hooks 32 on the same side of the locking frame 31. T-shaped grooves 35 are formed at the rear end of the locking frame 31 at the position of the locking hooks 32, and the two T-shaped grooves 35 on the same side of the locking frame 31 are connected by a through hole. The front end of each locking hook 32 is fixed with a T-shaped slider for sliding within the T-shaped groove 35. The connecting rod 33 is slidably connected within the through hole. A door panel 4 is hinged to the front side of the locking frame 31. A door lock 5 is fixed to the door panel 4 away from the door hinge. Two pull ropes 6 are detachably connected to the rear side of the locking frame 31, and the other ends of the two pull ropes 6 are fixed to the two sides of the top of the base frame 13. Sealing gaskets are provided at the contact points between the side plate 21 and the top frame 11, the back frame 12, and the base frame 13, as well as at the top and bottom of the rear end of the locking frame 31. When installation or maintenance is required, sealing gaskets are provided. When protecting the electrical meter components inside the distribution box, release the door lock 5 and open the door panel 4. Then press the lock hooks 32 on both sides of the rear end of the locking frame 31, causing the lock hooks 32 to slide downwards along the T-shaped slide groove 35. At the same time, the connecting rod 33 drives the lock hooks 32 on the lower side of the locking frame 31 to move downwards synchronously with the lock hooks 32 on the upper side. At this time, the push spring 34 inside the T-shaped slide groove 35 will be compressed, and the rear end of the lock hook 32 moves downwards along the lock opening 23. Then, flip the locking frame 31 forward so that the rear end of the lock hook 32 is completely out of the lock opening. 23. With the front side retracted, the side strip 22 disengages from the latch of the locking hook 32 and can be flipped outward to open the side plate 21. As the locking frame 31 flips forward to a horizontal position, the two pull ropes 6 on the top sides of the base frame 13 pull the rear side of the locking frame 31, thereby keeping the locking frame 31 in a horizontal position. This makes it convenient for maintenance personnel to place tools or electrical components that need maintenance. Alternatively, the front end of the pull rope 6 can be detached from the locking frame 31, allowing the locking frame 31 to hang down completely, thus allowing it to be closer to the distribution box for easier operation.

[0037] Working principle: When the distribution box is in use, the frame 12 is used to support the mounting frame 14, and the corresponding electricity meter device is installed through the mounting frame 14. The top frame 11 and the bottom frame 13 are used to enclose the top and bottom of the entire distribution box. Then, the side plates 21 on both sides of the frame 12 are used to enclose the two sides of the entire distribution box. At the same time, the cooling fan 24 can ventilate the entire distribution box to reduce the temperature inside the distribution box.

[0038] When it is necessary to install or maintain the electrical meter components in the distribution box, release the door lock 5 and open the door panel 4. Then press down on the locking hooks 32 on both sides of the rear end of the locking frame 31, so that the locking hooks 32 slide down along the T-shaped slide 35. At the same time, the connecting rod 33 drives the locking hooks 32 located on the lower side of the locking frame 31 to move down synchronously with the locking hooks 32 on the upper side. At this time, the push spring 34 inside the T-shaped slide 35 will be compressed. At the same time, the rear end of the locking hook 32 moves down along the lock opening 23. Then, flip the locking frame 31 forward so that the rear end of the locking hook 32 completely exits from the front side of the lock opening 23. At this time, the side strip 22 disengages from the locking hook 32 and can be flipped outward to open the side panel 21. Then, the entire distribution box can be opened on both sides, thereby expanding the operating space when maintaining the distribution box.

[0039] Once the locking frame 31 is flipped forward to a horizontal position, the two pull ropes 6 on both sides of the top of the base frame 13 pull the rear side of the locking frame 31, thereby keeping the locking frame 31 in a horizontal position. This makes it convenient for maintenance personnel to place tools or electrical components that need to be maintained. Alternatively, the front end of the pull rope 6 can be detached from the locking frame 31, allowing the locking frame 31 to hang down completely, thus allowing it to be closer to the distribution box for easier operation.

[0040] In addition, after the maintenance of the distribution box is completed, flip the two side panels 21 forward so that they overlap with the side of the frame 12, and then flip the locking frame 31 upward. At this time, the four locking hooks 32 at the rear end of the locking frame 31 will be inserted into the locking holes 23 of the two side strips 22. At this time, the locking holes 23 of the side strips 22 are locked with the locking hooks 32. At the same time, the upper end of the locking frame 31 abuts against the front side of the top frame 11. Then, the C-shaped frame, the two side panels 21 and the locking frame 31 form a stable electrical box frame. Then, the door panel 4 can be closed and the door lock 5 can be locked. Then, the sealing gaskets on the side panels 21 and the locking frame 31 are used to seal the gaps in the entire distribution box to prevent insects from entering the distribution box.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
