Description

Technical Field

[0001] The utility model belongs to the technical field of distribution boxes, and specifically relates to a distribution box that is convenient for maintenance. Background Technique

[0002] A distribution box is an electrical equipment used in the power transmission and distribution system, which has the characteristics of small volume, simple installation, special technical performance, fixed position, unique configuration function, not restricted by the site, wide application, stable and reliable operation, high space utilization rate, less floor area and environmental protection effect.

[0003] The distribution box includes a box body and a box door movably installed on the box body. After the box door is flipped open, the electricity meter in the box body can be read or repaired and detected. When the box door is not locked, it is easily affected by external forces and opens and closes randomly, resulting in the continuous exposure of the internal components of the box body to the outside world, and it is easy to be accidentally touched by others, causing danger. To avoid this situation, the operator needs to lock the box door before leaving the distribution box every time, and unlock the box door when it is necessary to open the distribution box again.

[0004] It can be seen that for the existing distribution box, when the operator repairs it, when the repair work cannot be completed at one time, it is necessary to unlock and lock the box door multiple times, which is rather inconvenient. It is necessary to design a distribution box that can overcome this problem. Content of the Utility Model

[0005] For the existing distribution box, it lacks a structure that can temporarily fix the box door and is convenient for releasing the fixation, resulting in that once the operator leaves the distribution box, it is necessary to use a key to lock and unlock the box door, which reduces the efficiency of the repair work. To solve this problem, the following utility model is proposed:

[0006] A distribution box that is convenient for maintenance, including a box body and a box door movably arranged on the box body. A backboard and a side plate are fixedly connected to the box body. A shaft seat and a rotating plate are arranged on the outer side of the side plate. A connecting shaft rotatably installed on the shaft seat is arranged on the rotating plate. An elastic mechanism is fixedly arranged on each side of the connecting shaft. A retractable pressing head is elastically connected in the elastic mechanism. The pressing head abuts against the side plate. A clamping head is also arranged on the rotating plate, which, when the box door is closed, clamps against the outer side of the box door to prevent the box door from flipping outwards. After pressing the rotating plate to make the pressing head in the elastic mechanism close to the backboard contract, the clamping head rotates outwards together with the rotating plate, and the box door can flip outwards. After releasing the rotating plate, the rotating plate resets.

[0007] Further, each elastic mechanism includes a plurality of mounting seats fixedly installed on the rotating plate in a vertical arrangement. An installation groove is provided in the mounting seat, and a cover plate that blocks the opening of the installation groove is fixedly installed on the mounting seat. One end of the pressing head is elastically installed in the installation groove, and the other end penetrates through the cover plate and contacts the side plate.

[0008] Further, the cover plate is provided with insertion blocks that are fitted and inserted into the installation groove. A plurality of fixing cylinders are provided in the installation groove, and the insertion blocks are provided with fixing columns that are fixedly inserted into the fixing cylinders one by one to fixedly connect the cover plate and the mounting seat.

[0009] Further, an annular groove is provided in each of the pressing head and the installation groove, and a spring that elastically connects the pressing head and the mounting seat is inserted between the annular grooves.

[0010] Further, the rotating plate is provided with mounting holes, and the mounting seats are fitted and inserted into the mounting holes. First fixing plates that are attached to one side of the rotating plate are provided on the upper and lower sides of the cover plate, and second fixing plates that are attached to the other side of the rotating plate are provided on the upper and lower sides of the mounting seat. The first fixing plates and the second fixing plates are fixedly connected to the rotating plate.

[0011] Further, a fixing hole is provided on each of the upper and lower sides of each mounting hole. A fixing rod that penetrates the fixing hole and the second fixing plate is provided on the first fixing plate, and a fixing head that blocks the outside of the second fixing plate is threadedly connected to the end of the fixing rod.

[0012] Further, the guiding inclined surface is driven by the contact of the box door to drive the engaging head to rotate outward. After the box door is completely closed, the engaging head resets and engages on the outside of the box door. The setting of the guiding inclined surface enables the operator not to press the rotating plate when closing the box door.

[0013] Further, a pulling plate that extends vertically outward is provided on the rotating plate. After pulling the pulling plate, the rotating plate is driven to rotate to one side. The pulling plate facilitates the operator to rotate the rotating plate.

[0014] The present utility model provides a distribution box that is convenient for maintenance. A rotating plate is movably installed on the box body. Elastic mechanisms that are elastically in contact with the box body are provided on both sides of the rotating plate. The box door is fixed by engaging the rotating plate with the box door, so that when the operator needs to temporarily leave during the maintenance process of the distribution box, there is no need to lock the box door, which is relatively convenient.

For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0028] In this application, the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "front", "rear", "top", "bottom", "inner", "outer", "middle", "vertical", "horizontal", "lateral", "longitudinal", etc. is based on the orientation or positional relationship shown in the drawings. These terms are mainly used to better describe the present utility model and its embodiments, and are not used to limit that the indicated devices, elements or components must have a specific orientation, or be constructed and operated in a specific orientation.

[0029] In addition to being used to represent the orientation or positional relationship, some of the above terms may also be used to represent other meanings. For example, the term "upper" may also be used to represent a certain attachment relationship or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in the present utility model can be understood according to specific circumstances.

[0030] As Figures 1-4 shown, it is a preferred embodiment of the present utility model, a distribution box convenient for maintenance, including a box body 1 and a box door 2 movably installed on the box body 1 through a hinge 22. A door lock 21 capable of locking it is provided on the box door 2. Only when the door lock 21 is in the unlocked state can the box door 2 be flipped open. After that, the electricity meter in the box body 1 can be read or repaired and detected. Each of the two side parts of the box body 1 is provided with a side plate 11. A back plate 12 is fixedly arranged between the two side plates 11. An axle seat 13 and a rotating plate 3 are provided on the outer side of the side plate 11 close to the closing side of the box door 2. A connecting plate 36 is arranged on the inner side of the rotating plate 3 to cooperate with the upper and lower sides of the axle seat 13. Through holes vertically penetrating are provided on the connecting plate 36 and the axle seat 13. A connecting shaft 23 is movably arranged in the through holes to rotatably mount the rotating plate 3 on the side plate 11. Elastic mechanisms 4 are fixedly arranged on both sides of the connecting shaft 23. As Figure 6 and Figure 7 shown, a retractable pressing head 43 is elastically connected in the elastic mechanism 4. The pressing head 43 also abuts against the side plate 11. The left side of the rotating plate 3 is the head part, and a clamping head 31 is provided on the head part. A guiding inclined surface 32 is provided on the outer side of the clamping head 31.

[0031] After the box door 2 is completely closed, the engaging head 31 is engaged with the outside of the box door 2 to prevent the box door 2 from being turned outward under the influence of external force in the unlocked state. By pressing the tail part on the right side of the rotating plate 3, that is, the part of the rotating plate 3 close to the back plate 12, the elastic mechanism 4 closer to the back plate 12 will move towards the side plate 11. At the same time, the pressing head 43 in the elastic mechanism 4 elastically contracts inward. The head of the rotating plate 3 drives the engaging head 31 to rotate outward and releases the engagement with the box door 2. At this time, the box door 2 can be freely turned outward and opened. During the process of closing the box door 2, after the side of the box door 2 touches the guiding inclined surface 32, it will automatically press against the engaging head 31 to rotate outward without the operator pressing the tail part of the rotating plate 3. When the box door 2 is completely closed, the engaging head 31 and the rotating plate 3 return to the initial position and are re-engaged with the outside of the box door 2. Then, the box door 2 can be locked or kept in the unlocked state according to actual needs. The elastic mechanism 4 close to the box door 2 prevents the rotating plate 3 from rotating excessively during the rotation and reset process.

[0032] When the box door 2 is engaged by the engaging head 31, it will not be turned outward under the influence of external force, avoiding accidental contact with the inside of the box body 1, which is relatively safe. Moreover, whether opening or closing the box door 2, only the rotating plate 3 needs to be rotated, which is relatively convenient and efficient. In addition, during the maintenance process, when the external force on the box door 2 is small, it will not be able to close due to the blocking of the engaging head 31 to prevent the box door 2 from being completely closed during the operator's maintenance process, reducing interference with the operator's maintenance process.

[0033] The specific structure of the elastic mechanism 4 will be further described in detail below. As Figure 5 shown, three vertically arranged mounting holes 34 penetrating the rotating plate 3 are provided on both sides of the connecting shaft 23. Mounting seats 41 are inserted and fitted in the mounting holes 34. Each mounting seat 41 is provided with a mounting groove 42 with an opening facing the side plate 11. A cover plate 5 that blocks the opening of the mounting groove 42 is fixedly installed on the outside of the mounting seat 41. One end of the pressing head 43 is elastically installed in the mounting groove 42, and the other end penetrates the cover plate 5 and contacts the side plate 11. After the rotating plate 3 rotates to one side, the pressing head 43 of the elastic mechanism 4 close to that side elastically moves into the mounting groove 42.

[0034] As Figures 6-8 shown, an insertion block 51 is provided on the cover plate 5 and is inserted and fitted into the mounting groove 42. A plurality of fixing cylinders 46 are provided in the mounting groove 42. Fixing columns 52 that are fixedly inserted into the fixing cylinders 46 one by one are provided on the insertion block 51 to fixedly connect the cover plate 5 and the mounting seat 41. An annular groove 45 is provided on each of the pressing head 43 and the mounting groove 42, and a spring 44 that elastically connects the pressing head 43 and the mounting seat 41 is inserted between the annular grooves 45.

[0035] Further, a fixing hole 35 penetrating through the rotating plate 3 is provided on each of the upper and lower sides of each mounting hole 34. A first fixing plate 55 fitting against the inner side of the rotating plate 3 is provided on each of the upper and lower sides of the cover plate 5. A second fixing plate 47 fitting against the outer side of the rotating plate 3 is provided on each of the upper and lower sides of the mounting seat 41. A fixing rod 53 horizontally penetrating through the fixing hole 35 and the second fixing plate 47 is provided on the first fixing plate 55. A fixing head 54 is threadedly connected to the end of the fixing rod 53. The fixing head 54 fits against and blocks the outer side of the second fixing plate 47 to prevent the cover plate 5 and the mounting seat 41 from separating from each other.

[0036] A pulling plate 33 extending vertically outward is further provided on the rotating plate 3. After pulling the pulling plate 33, the rotating plate 3 can be driven to rotate to one side, so as to facilitate the operator to quickly operate the rotating plate 3.

[0037] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
