Description

Technical Field

[0001] This application relates to the field of distribution cabinets, and in particular to a distribution cabinet with anti-misinsertion function. Background Art

[0002] A distribution cabinet is a device that distributes the connected main line to each using device. There are various forms of distribution cabinets. One of them is to set several drawers, and different circuits are set in each drawer. Generally, plugs are set on the drawers to connect with the sockets in the distribution cabinet. In order to reduce the misinsertion of the drawers into the wrong positions on the distribution cabinet, corresponding anti-misinsertion devices are set to ensure that the drawers are inserted into the corresponding positions in the distribution cabinet.

[0003] Some existing distribution cabinets will set slides, and sliders that move in the slides are set on the drawers. The shapes of each drawer are inconsistent, so that only when each drawer is inserted into the correct position in the corresponding distribution cabinet, the corresponding slider can enter the slide, enabling the drawer to be installed smoothly. For example, the patent with the publication number CN209497130U and the name of a low-voltage drawer cabinet with anti-misinsertion function.

[0004] Regarding the above related technologies, the areas of the sliders are different in size. When the slider with a smaller area corresponds to the slide with a larger area, the slider can still move smoothly in the slide. At this time, there is still a greater possibility that the drawer is inserted into the wrong position on the distribution cabinet. Summary of the Invention

[0005] In order to reduce the possibility of the drawer being inserted into the wrong position on the distribution cabinet, this application provides a distribution cabinet with anti-misinsertion function.

[0006] The distribution cabinet with anti-misinsertion function provided by this application adopts the following technical solutions.

[0007] A distribution cabinet with anti-misinsertion function includes a cabinet body for connecting the main line, and several drawers inserted into the cabinet body and whose internal circuits can be electrically connected to the main line in the cabinet body. One end of the drawer inserted into the cabinet body is provided with a main wedge block. A buffer block is arranged in the cabinet body. A secondary wedge block that can abut against the main wedge block and is forced to retract into the cabinet body is slidably connected to the buffer block. A pushing spring for forcing the main wedge block to extend out of the buffer block is arranged in the buffer block. The buffer block is provided with a limiting and disengaging block that can abut against the secondary wedge block. A positioning groove for inserting the main wedge block is formed in the cabinet body. The side of the drawer provided with the main wedge block can abut against the secondary wedge block to prompt the wrong installation of the drawer.

[0008] By adopting the above technical solution, when the drawer is inserted into the corresponding cabinet body, the main wedge block will abut against the secondary wedge block, causing the secondary wedge block to retract into the cabinet body so that the secondary wedge block will no longer block the proper insertion of the drawer. When the drawer is not inserted into the correct position, the secondary wedge block will abut against the drawer or the main wedge block will abut against the corresponding inner wall of the cabinet body, making it impossible for the drawer to be inserted in place, thus prompting the operator that the installation position of the drawer is incorrect and making it less likely for the installation position of the drawer to be wrong.

[0009] Optionally, the main wedge block is slidably connected to the drawer. A wedge spring for forcing the main wedge block to extend out of the drawer is provided inside the drawer. The main wedge block is provided with an anti - detachment block that can abut against the inside of the drawer. The elastic modulus of the wedge spring is greater than that of the pushing spring.

[0010] By adopting the above technical solution, when the drawer is installed incorrectly and there is no alignment slot in the corresponding cabinet body for a part of the main wedge block to be inserted, the main wedge block will directly abut against the inner wall of the cabinet body and the wedge spring will be compressed, making it difficult for the main wedge block, the cabinet body, and the drawer to be subjected to a large impact. After the operator no longer applies force to the drawer, the wedge spring will push the main wedge block out, causing the drawer to be pushed out of the cabinet body by a part, so as to prompt the operator that the installation position of the corresponding drawer is incorrect.

[0011] Optionally, the buffer block is slidably connected to the cabinet body. A buffer spring for forcing the buffer block to move in the opposite direction to the insertion of the drawer into the cabinet body is provided inside the cabinet body. The elastic modulus of the buffer spring is greater than that of the pushing spring.

[0012] By adopting the above technical solution, when the drawer is inserted into the wrong position and the drawer abuts against the secondary wedge block, the buffer block will be driven to move at this time, causing the buffer spring to be compressed accordingly, making it difficult for a large impact to occur between the drawer and the secondary wedge block.

[0013] Optionally, the alignment slot communicates with the position in the cabinet body where the buffer block moves, and the buffer block can enter the alignment slot.

[0014] By adopting the above technical solution, the buffer block can completely enter the alignment slot, making it difficult for the buffer block or the secondary wedge block to impact the inner wall of the cabinet body.

[0015] Optionally, several cleaning pieces are slidably connected inside the cabinet body. Each cleaning piece fits against the inner bottom surface of the cabinet body at the position where a drawer is inserted. A piece driving device for driving the cleaning pieces to move is provided inside the cabinet body.

[0016] By adopting the above technical solution, before the drawer is inserted into the cabinet body, the cleaning piece moves first to clean the inside of the cabinet body, so that it is not easy for some sundries to exist between the bottom surface of the drawer and the inside of the cabinet body. When the drawer is inserted, the drawer is not easy to be stuck, and when the drawer is inserted into the wrong position, it can smoothly pop out a part.

[0017] Optionally, the cleaning piece is provided with a negative pressure block, and the air inlet of the negative pressure block is inclined and faces the surface of the inner wall of the cabinet body where the cleaning piece fits.

[0018] By adopting the above technical solution, the negative pressure block removes some dust or sundries with less adhesion in the cabinet body, making the inside of the cabinet body have better cleanliness.

[0019] Optionally, the piece driving device includes a lead screw block slidably connected to the cabinet body and fixedly connected to the upper part of the cleaning piece, a driving lead screw threadedly connected to the lead screw block and rotatably connected to the cabinet body, and a rotation mechanism arranged inside the cabinet body and capable of synchronously rotating all the driving lead screws.

[0020] By adopting the above technical solution, the rotation of the driving lead screw makes the lead screw block move stably, and the lead screw block is connected to the upper part of the cleaning piece, so that it is not easy for sundries to enter the position where the driving lead screw is arranged in the cabinet body.

[0021] Optionally, the rotation mechanism includes several worm gears rotatably connected to the cabinet body, worm wheels rotatably connected to the cabinet body and meshing with each worm gear one by one, a main gear coaxially and fixedly connected to the worm wheel, a lead screw gear coaxially and fixedly connected to the driving lead screw, middle gears rotatably connected to one of the slave wedges corresponding to each drawer and capable of meshing with the corresponding main gear and lead screw gear, gear rods arranged on the slave wedges corresponding to each middle gear and for the middle gears to be rotatably connected, and a worm motor arranged on the cabinet body and driving the worm gear to rotate. All the worm gears are coaxially and fixedly connected.

[0022] By adopting the above technical solution, when the drawer is removed from the cabinet body, the slave wedge moves so that the middle gear meshes with the main gear and the lead screw gear, enabling the corresponding cleaning piece to move. For the drawers that are not pulled out, due to the main wedge or forcing the slave wedge to retract into the cabinet body, there is a gap between the middle gear, the main gear, and the lead screw gear, so that the corresponding cleaning piece does not move. When one worm motor works, only the cleaning pieces in the cabinet bodies where the drawers are pulled out will move accordingly.

[0023] Optionally, an insertion groove for the cleaning piece and the negative pressure block to enter is formed in the cabinet body.

[0024] By adopting the above technical solution, one end inner wall of the drawer in the cabinet body can abut against the inner wall of the cabinet body, so that the drawer is not easy to abut against the cleaning piece or the negative pressure block, and the cleaning piece and the negative pressure block are not easy to bear a large external force.

[0025] Optionally, the cleaning piece is inclined, and the air inlet of the negative pressure block faces the side where the cleaning piece fits against the inner side of the cabinet body.

[0026] By adopting the above technical solutions, before the cleaning piece moves to clean the inside of the cabinet body, the negative pressure block can first clean the inside of the cabinet body, and some sundries scraped off by the cleaning piece can also be just sucked away by the negative pressure block, making the cleanliness of the inside of the cabinet body higher.

[0027] In summary, the present application includes at least one of the following beneficial effects:

[0028] 1. When the drawer is not inserted into the correct position, the follower wedge will abut against the drawer or the main wedge will abut against the corresponding inner wall of the cabinet body, making it impossible for the drawer to be inserted in place, so as to prompt the operator that the installation position of the drawer is incorrect, and it is more difficult for the installation position of the drawer to be incorrect;

[0029] 2. It is not easy for some sundries to exist between the bottom surface of the drawer and the inside of the cabinet body, so that when the drawer is inserted, the drawer is not easy to be stuck. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0037] The following further elaborates on this application with reference to the accompanying drawings.

[0038] An embodiment of this application discloses a distribution cabinet that prevents misinsertion. Refer to Figure 1 and Figure 2 , which includes a cabinet body 1 placed on the ground. A plurality of drawer grooves 33 are opened in a vertical side of the cabinet body 1 along the vertical direction. A drawer 2 is provided in each drawer groove 33. A corresponding circuit is arranged in each drawer 2. A corresponding plug is arranged on the vertical side at one end of each drawer 2 in the cabinet body 1. A corresponding socket is arranged on the inner wall of the drawer groove 33. After the drawer 2 is inserted in place, the plug of the drawer 2 is correspondingly inserted into the socket of the drawer groove 33. The drawer 2 can be horizontally moved out of the drawer groove 33, and the drawer 2 can be locked with the cabinet body 1.

[0039] Refer to Figure 3 , several main wedge blocks 3 are provided at one end of the drawer 2 in the drawer groove 33. The number of main wedge blocks 3 of each drawer 2 is inconsistent. The length direction of the main wedge block 3 is the same as the direction in which the drawer 2 is inserted into the drawer groove 33.

[0040] Refer to Figure 2 and Figure 4 , several buffer blocks 34 are provided in each drawer groove 33. The number of buffer blocks 34 in each drawer groove 33 is the same as the number of main wedge blocks 3 of the corresponding drawer 2. A secondary wedge block 5 that can abut against the corresponding main wedge block 3 is slidably connected in each buffer block 34. The moving direction of the secondary wedge block 5 and the length direction of the main wedge block 3 are in the same horizontal plane. The moving direction of the secondary wedge block 5 is perpendicular to the length direction of the main wedge block 3. The side surface of the secondary wedge block 5 that abuts against the main wedge block 3 is inclined, so that the main wedge block 3 can force the secondary wedge block 5 to retract into the buffer block 34.

[0041] Refer to Figure 5 and Figure 6, a pushing spring 51 that forces the follower wedge 5 to protrude from the buffer block 34 is provided inside the buffer block 34. End blocks 35 are integrally formed on both opposite sides of the end of the follower wedge 5 located in the buffer block 34. The end blocks 35 are slidably connected to the inner wall of the buffer block 34. A limited detachment block 52 is fixedly connected to the inner wall of the opening at one end of the buffer block 34 where the follower wedge 5 extends into. The end blocks 35 can abut against the limited detachment block 52, making it difficult for the follower wedge 5 to completely disengage from the buffer block 34.

[0042] Referring to Figure 4 , several alignment slots 53 are provided on the vertical inner wall of the drawer slot 33 facing the main wedge 3. Each alignment slot 53 allows a main wedge 3 to be inserted along the direction in which the drawer 2 is inserted into the drawer slot 33.

[0043] If the drawer 2 is inserted into the wrong drawer slot 33, two situations will occur. One is that the number of main wedges 3 is greater than the number of follower wedges 5. At this time, the number of alignment slots 53 is less than the number of main wedges 3, so that some main wedges 3 cannot be inserted into the alignment slots 53, making it impossible to install the drawer 2 in place. The other situation is that the number of main wedges 3 is less than the number of follower wedges 5. At this time, some of the follower wedges 5 cannot be retracted into the buffer block 34, so that the vertical end face of the drawer 2 provided with the main wedge 3 will abut against the follower wedge 5 that has not been retracted into the buffer block 34, and the side surface of the drawer 2 in contact with the follower wedge 5 is parallel, that is, the drawer 2 will not abut against the inclined surface of the follower wedge 5, making it impossible for the drawer 2 to force the follower wedge 5 to retract into the buffer block 34, so that the drawer 2 cannot be installed in place at this time.

[0044] Referring to Figure 3 , the main wedge 3 is slidably connected to the drawer 2 along its own length direction. A wedge spring 54 that forces the main wedge 3 to protrude from the drawer 2 is fixedly connected between the drawer 2 and the main wedge 3. When the drawer 2 is inserted into the wrong position and the number of main wedges 3 is greater than the number of follower wedges 5, the main wedge 3 will retract into the drawer 2. When the drawer 2 is no longer under the action of the operator, the wedge spring 54 elongates to push the drawer 2 out of the drawer slot 33 by a part to remind the operator that the drawer 2 is installed incorrectly. At the same time, the elastic modulus of the wedge spring 54 is greater than that of the pushing spring 51, so that when the main wedge 3 abuts against the follower wedge 5, it is not easy for the main wedge 3 to retract into the drawer 2 so that the follower wedge 5 can smoothly retract into the buffer block 34 at this time. An inner block 36 is integrally formed on one side of one end of the main wedge 3 located in the drawer 2. The inner block 36 is slidably connected to the inside of the drawer 2. An anti-detachment block 55 is fixedly connected to the inner wall of the opening of the drawer 2 for the main wedge 3 to slide. The inner block 36 can abut against the anti-detachment block 55, making it difficult for the main wedge 3 to disengage from the drawer 2. Since the main wedge 3 is slidably connected to the drawer 2, a small part of the periphery of the vertical side surface of the drawer 2 provided with the main wedge 3 will come into contact with the inclined surface of the follower wedge 5, forcing the follower wedge 5 to completely retract into the buffer block 34.

[0045] Referring toFigure 4 The drawer slot 33 is provided with a block sliding slot 37 vertically opened on the vertical inner wall perpendicular to the moving direction of the wedge block 5. The length direction of the block sliding slot 37 is consistent with the direction in which the drawer 2 is inserted into the drawer slot 33. The buffer block 34 is slidably connected to the block sliding slot 37 along the length direction of the block sliding slot 37. A slide rail can be arranged in the block sliding slot 37 for the stable movement of the buffer block 34. A buffer spring 56 is fixedly connected between the inside of the block sliding slot 37 and the buffer block 34. The buffer spring 56 forces the buffer block 34 to move towards the opening of the drawer slot 33. The alignment slot 53 communicates with the block sliding slot 37 so that the buffer block 34 can enter the alignment slot 53, and the side of the drawer 2 provided with the main wedge block 3 can abut against the inner wall of the drawer slot 33 where the alignment slot 53 is opened. When the drawer 2 is inserted at the wrong position and the number of main wedge blocks 3 is less than the number of secondary wedge blocks 5, the drawer 2 abuts against the secondary wedge blocks 5 so that the secondary wedge blocks 5 and the buffer block 34 move synchronously, causing the buffer spring 56 to be compressed. When the drawer 2 is no longer under the action of the operator, the buffer spring 56 elongates, pushing the drawer 2 out of the drawer slot 33 by a part. The elastic modulus of the buffer spring 56 is greater than that of the pushing spring 51, so that the buffer spring 56 is not easily compressed when the main wedge block 3 abuts against the secondary wedge block 5.

[0046] Refer to Figure 2 and Figure 4 As shown in and, on the vertical inner wall of each drawer slot 33 along the moving direction of the buffer block 34, a sheet sliding slot 38 is opened. The sheet sliding slot 38 penetrates to the opening of the drawer slot 33. A cleaning sheet 58 is slidably connected to the sheet sliding slot 38 along its own length direction. The cleaning sheet 58 is inclined and its bottom abuts against the bottom inner wall of the drawer slot 33. A negative pressure block 41 is fixedly connected to the upper part of the cleaning sheet 58. The negative pressure block 41 communicates with the air inlet of a vacuum pump arranged in the cabinet 1, so that the opening of the negative pressure block 41 can suck in dust, impurities, etc. on the inner bottom surface of the drawer slot 33. The opening of the negative pressure block 41 is inclined and faces the side where the cleaning sheet 58 contacts the inner bottom surface of the drawer slot 33. The opening of the negative pressure block 41 is located on the side of the cleaning sheet 58 facing the opening of the drawer slot 33. When the cleaning sheet 58 starts to move towards the side of the opening of the drawer slot 33, the negative pressure block 41 first sucks away some dust and impurities, and then the cleaning sheet 58 removes some impurities that may be adsorbed on the inner bottom surface of the drawer slot 33, so as to improve the cleanliness of the inner bottom surface of the drawer slot 33 and reduce the possibility of the drawer 2 being stuck when inserted into the drawer slot 33. At the same time, a moving-in slot 32 is opened on the vertical inner wall of the drawer slot 33 where the alignment slot 53 is opened. The moving-in slot 32 communicates with the sheet sliding slot 38, and the cleaning sheet 58 and the negative pressure block 41 can enter the moving-in slot 32 as a whole.

[0047] Refer to Figure 4, a lead screw groove 39 is formed on the upper surface of the piece chute 38 along its length direction. A piece driving device 59 for driving the cleaning piece 58 to move is arranged in the cabinet body 1. The piece driving device 59 includes a driving lead screw 43 rotatably connected to the inner wall of the lead screw groove 39. The driving lead screw 43 passes through and is threadedly connected with a lead screw block 42. The lead screw block 42 is slidably connected in the lead screw groove 39 along the length direction of the lead screw groove 39. The lead screw block 42 is fixedly connected to the upper surface of one end of the cleaning piece 58 located in the piece chute 38. A synchronous rotation mechanism 44 capable of synchronously rotating all the driving lead screws 43 is arranged inside the cabinet body 1.

[0048] Refer to Figure 5 , the synchronous rotation mechanism 44 includes a lead screw gear 48 coaxially and fixedly connected to the driving lead screw 43. One end face of each follower wedge block 5 on the same side of each drawer slot 33 is fixedly connected to a gear rod 21. The gear rod 21 passes through the end face of the buffer block 34 far from the follower wedge block 5. The gear rod 21 can be slidably connected to the buffer block 34 along the moving direction of the follower wedge block 5 in the buffer block 34. At the same time, the gear rod 21 can be slidably connected to the inside of the cabinet body 1 along the length direction of the block chute 37. One end of the gear rod 21 far from the follower wedge block 5 is rotatably connected to an intermediate gear 49 capable of meshing with the lead screw gear 48. Several main gears 47 are rotatably connected to the inside of the cabinet body 1. Each main gear 47 is located directly above a corresponding lead screw gear 48. The intermediate gear 49 and the follower wedge block 5 are located on both sides of the main gear 47 and the lead screw gear 48. Each main gear 47 is coaxially and fixedly connected to a worm gear 46. Each worm gear 46 is engaged with a worm 45 rotatably connected to the inside of the cabinet body 1. All the worms 45 are coaxially and fixedly connected to each other. A worm motor 31 is fixedly connected to the upper part of the cabinet body 1. The output shaft of the worm motor 31 is coaxially and fixedly connected to the worm 45.

[0049] The follower wedge block 5 corresponding to the drawer slot 33 without the drawer 2 is extended out of the buffer block 34, so that the intermediate gear 49 can be engaged with the main gear 47 and the lead screw gear 48. At this time, when the worm motor 31 is connected to an external power supply, the corresponding driving lead screw 43 can be rotated, so that the corresponding cleaning piece 58 moves. At this time, in the drawer slot 33 with the drawer 2 inside, since the follower wedge block 5 is retracted into the buffer block 34, there is a gap between the intermediate gear 49, the lead screw gear 48 and the main gear 47. At this time, the rotation of the main gear 47 cannot drive the rotation of the lead screw gear 48, so that the cleaning piece 58 in the drawer slot 33 with the drawer 2 will not move.

[0050] The implementation principle of a power distribution cabinet with anti-misinsertion in the embodiment of the present application is that only when the number of main wedge blocks 3 on the drawer 2 corresponds to the number of follower wedge blocks 5 in the drawer slot 33 and can be abutted against each other one by one, the drawer 2 will not pop out a part after being inserted in place, so as to clarify that the drawer 2 is in the correct drawer slot 33 at this time. Then, the drawer 2 and the inner wall of the corresponding drawer slot 33 can be locked.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present application shall be covered within the protection scope of the present application.
