Description

Technical Field

[0001] The present invention relates to the technical field of electric meter boxes, and specifically to a connector for an electric meter box and a related electric meter box. Background Technique

[0002] With the continuous development and improvement of the power system, it is widely used in different fields. In order to monitor the power usage situation, the installation quantity of electric energy meters is increasing year by year. At the same time, the electric energy meters will be replaced and repaired within a certain period of time, and there will also be situations where the electric energy meters malfunction during this period.

[0003] The patent document with the publication number of CN117054711A discloses an energy meter connector, which includes a base. A rotating bracket is connected to the base. A conductive member is arranged on the rotating bracket. The conductive member is detachably connected to an electric energy meter. When the rotating bracket rotates, it synchronously drives the conductive member and the electric energy meter to rotate. An opening and closing switch is arranged on the base. When the rotating bracket drives the conductive member to abut against the opening and closing switch, the conductive member is energized with the electric energy meter.

[0004] In the above application document, by rotatably connecting the rotating bracket to the base, the electric energy meter can be installed and disassembled obliquely. However, the limiting effect of its rotating bracket is poor, and the electric energy meter may flip after being installed on the rotating bracket, which is not conducive to the stable use of the electric energy meter. Therefore, it needs to be improved. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a connector for an electric meter box and a related electric meter box, which solves the problems raised in the above background technique.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A connector for an electric meter box and a related electric meter box, including a base, a protection plate is fixedly connected to the front end of the base, and a flipping and plugging mechanism is arranged inside the protection plate; the flipping and plugging mechanism includes a flipping plate and a fixing plate, a flipping seat is fixedly connected to the front end of the flipping plate, a connecting column penetrates and is fixedly connected to the top of the flipping seat, a wire penetrates and is fixedly connected to the bottom of the connecting column, a conductive block penetrates and is fixedly connected to the top of the connecting column, the wire is electrically connected to the conductive block, a rotating shaft is fixedly connected to the side of the flipping seat, the rotating shaft penetrates and is rotatably connected to the protection plate, a slot is opened at the top of the flipping plate, a groove is opened on the inner side wall of the slot, a telescopic spring is arranged inside the groove, an arc-shaped block is elastically connected to the inside of the groove through the telescopic spring, a pull rod is fixedly connected to the end of the arc-shaped block close to the telescopic spring, the fixing plate is fixedly connected to the front end of the flipping plate, a sliding rod is fixedly connected to the top of the fixing plate, a lifting plate is slidably connected to the surface of the sliding rod, a plug post is fixedly connected to the bottom of the lifting plate, a clamping groove is opened on the side of the plug post, a reset spring is sleeved on the surface of the sliding rod, an automatic protection component is arranged inside the connecting column, an automatic locking mechanism is arranged at the rear end of the flipping plate, and a one-way speed reduction mechanism is arranged on the side of the protection plate.

[0007] According to the above technical solution, the automatic protection component includes a slotted opening, the slotted opening is opened at the top of the connecting column, a compression spring is arranged inside the opening slot, a shielding plate is elastically connected to the inside of the opening slot through the compression spring, and the compression spring is in a compressed state under the initial state. When the bottom interface of the electric meter box main body is separated from the connecting column, the compression spring will rebound and drive the shielding plate to bounce upward to shield and protect the conductive block.

[0008] According to the above technical solution, the arc surface of the arc-shaped block faces the top of the slot, the pull rod penetrates and is slidably connected to the flipping plate, and when the arc surface of the arc-shaped block is squeezed, it will move into the groove, and the arc-shaped block can be driven to retract into the groove through the pull rod.

[0009] According to the above technical solution, the opening size of the slot corresponds to the plug post, and the opening size of the clamping groove is equal to the opening size of the groove. When the plug post moves downward, it will insert into the slot.

[0010] According to the above technical solution, the automatic locking mechanism includes a hydraulic chamber, an insertion seat, and an insertion bar. A piston rod A is slidably connected to the inside of one end of the hydraulic chamber. A pressure plate is fixedly connected to the end of the piston rod A away from the hydraulic chamber. A elastic spring is sleeved on the surface of the piston rod A. Piston rods B are slidably connected to the inside of the other two ends of the hydraulic chamber. At the ends of the two piston rods B away from the hydraulic chamber, clamping blocks are fixedly connected. The insertion seat is fixedly connected to the top of the flipping seat. The insertion bar is fixedly connected to the rear end of the electric meter box body. The insertion bar is inserted into the inside of the insertion seat. Locking grooves are formed on both sides of the insertion bar. A speed reduction wheel assembly is arranged on the top of the insertion seat. The speed reduction wheel assembly includes a connecting frame. The connecting frame is fixedly connected to the top of the insertion seat. A runner is rotatably connected to the inside of the connecting frame. An opening groove is formed on the surface of the runner. An elastic cord is arranged inside the opening groove. A resistance plate is elastically connected to the inside of the opening groove through the elastic cord.

[0011] According to the above technical solution, the end of the pressure plate away from the piston rod A is initially in contact with the front end of the flipping plate, and the elastic spring is initially in a compressed state. At the initial state, the ends of the two clamping blocks away from the piston rods B are respectively located in the two locking grooves. The side of the runner is initially in contact with the side of the insertion bar, and the resistance plate is initially completely inside the opening groove. The two clamping blocks are stuck in the two locking grooves, making it impossible for the insertion bar to move upward and leave the insertion seat.

[0012] According to the above technical solution, the one-way speed reduction mechanism includes a driving gear, a rotating rod, a cross bar, a fixed plate, and a limiting rod. The driving gear is fixedly connected to the end of the rotating shaft away from the flipping seat. The rotating rod is fixedly connected to the outside of the protective plate. A driven gear is fixedly connected to the surface of the rotating rod. A rotating block is fixedly connected to the end of the rotating rod away from the protective plate. A speed reduction airbag is fixedly connected to the surface of the rotating block. The cross bar, the fixed plate, and the limiting rod are all fixedly connected to the outside of the protective plate. A rotating plate is rotatably connected to the surface of the cross bar. A spring telescopic rod is fixedly connected to the bottom of the fixed plate. The telescopic end of the spring telescopic rod is fixedly connected to the rotating plate.

[0013] According to the above technical solution, the end of the rotating plate away from the cross bar is arc-shaped, and the end of the rotating plate away from the cross bar is close to the surface of the rotating block. When the rotating block rotates, it will drive the speed reduction airbag to contact the arc-shaped end of the rotating plate.

[0014] According to the above technical solution, the driving gear meshes with the driven gear. The limiting rod is close to the rotating plate. The speed reduction airbag is generally semi-cylindrical. The limiting rod makes the rotating plate only deflect clockwise. When the speed reduction airbag is squeezed with the arc-shaped end of the rotating plate, a large resistance will be generated.

[0015] An electricity meter box includes a main body of the electricity meter box. A display screen is provided at the front end of the main body of the electricity meter box. An interface is opened at the bottom of the main body of the electricity meter box, and a conductive member is arranged inside the interface.

[0016] The present invention provides a connector for an electricity meter box and a related electricity meter box, which have the following beneficial effects: (1) Through the setting of the flipping and plugging mechanism of the present invention, when installing or disassembling the main body of the electricity meter box, the flipping plate can be flipped to drive the flipping seat to flip a certain angle, so as to facilitate the installation and disassembly of the main body of the electricity meter box. After the main body of the electricity meter box is installed, the flipping plate and the flipping seat can be stably limited by the cooperation of components such as the plug post, the slot, and the arc-shaped block, ensuring the stability of the main body of the electricity meter box during operation.

[0017] (2) Through the setting of the automatic locking mechanism of the present invention, when the flipping plate and the flipping seat are in a vertical state, the two sets of clamping blocks will be stuck in the locking groove, making the insertion bar unable to move upward and leave the insertion seat, thereby locking the position of the main body of the electricity meter box. At the same time, during the process of the insertion bar moving downward along the insertion seat, the reduction gear assembly will slow down the insertion bar to prevent it from moving too fast due to gravity and causing impact. When flipping the flipping plate to drive the flipping seat to flip a certain angle for disassembly work, the two sets of clamping blocks will leave the locking groove. At this time, the main body of the electricity meter box can move upward to drive the insertion bar to leave the insertion seat, so as not to affect the disassembly work.

[0018] (3) Through the setting of the one-way speed reduction mechanism of the present invention, when flipping the flipping plate to drive the flipping seat to flip a certain angle for disassembly work, the speed of the flipping plate and the flipping seat when flipping downward will be slowed down through the cooperation of components such as the driving gear, the driven gear, the rotating plate, and the speed reduction airbag, preventing the main body of the electricity meter box from being damaged due to too fast flipping speed. When flipping the flipping plate and the flipping seat upward to restore them, it will not be affected too much. Description of the Drawings

Specific embodiments

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0037] Please refer to Figure 1-11, an embodiment of the present invention is: a connector for an electric meter box, including a base 1, a protective plate 2 is fixedly connected to the front end of the base 1, and a flip plugging mechanism 3 is arranged inside the protective plate 2; the flip plugging mechanism 3 includes a flip plate 31 and a fixing plate 312. A flip seat 32 is fixedly connected to the front end of the flip plate 31. A connecting column 33 penetrates and is fixedly connected to the top of the flip seat 32. A wire 34 penetrates and is fixedly connected to the bottom of the connecting column 33. A conductive block 35 penetrates and is fixedly connected to the top of the connecting column 33. The wire 34 is electrically connected to the conductive block 35. A rotating shaft 36 is fixedly connected to the side of the flip seat 32. The rotating shaft 36 penetrates and is rotatably connected to the protective plate 2. A slot 37 is formed in the top of the flip plate 31. A groove 38 is formed in the inner side wall of the slot 37. A telescopic spring 39 is arranged inside the groove 38. An arc-shaped block 310 is elastically connected inside the groove 38 through the telescopic spring 39. One end of the arc-shaped block 310 close to the telescopic spring 39 is fixedly connected to a pull rod 311. The fixing plate 312 is fixedly connected to the front end of the flip plate 31. A sliding rod 313 is fixedly connected to the top of the fixing plate 312. A lifting plate 314 is slidably connected to the surface of the sliding rod 313. A plug post 315 is fixedly connected to the bottom of the lifting plate 314. A card slot 316 is formed in the side of the plug post 315. A reset spring 317 is sleeved on the surface of the sliding rod 313. The arc surface of the arc-shaped block 310 faces the top of the slot 37. The pull rod 311 penetrates and is slidably connected to the flip plate 31. When the arc surface of the arc-shaped block 310 is squeezed, it will move into the groove 38. The arc-shaped block 310 can be driven to retract into the groove 38 through the pull rod 311. The opening size of the slot 37 corresponds to the plug post 315, and the opening size of the card slot 316 is equal to the opening size of the groove 38. When the plug post 315 moves downward, it will insert into the slot 37. An automatic protection component 8 is arranged inside the connecting column 33. The automatic protection component 8 includes an opening groove 81, which is opened at the top of the connecting column 33. A compression spring 82 is arranged inside the opening groove 81. A shielding plate 83 is elastically connected inside the opening groove 81 through the compression spring 82. The compression spring 82 is in a compressed state in the initial state. When the bottom interface of the electric meter box body 4 is separated from the connecting column 33, the compression spring 82 will rebound and drive the shielding plate 83 to bounce upward to shield and protect the conductive block 35. An automatic locking mechanism 5 is arranged at the rear end of the flip plate 31, and a one-way speed reduction mechanism 6 is arranged on the side of the protective plate 2. The automatic locking mechanism 5 includes a hydraulic chamber 51, an insertion seat 57 and an insertion bar 58. A piston rod A52 is slidably connected to the inner piston at one end of the hydraulic chamber 51. The end of the piston rod A52 away from the hydraulic chamber 51 is fixedly connected to a pressure plate 53. A elastic spring 54 is sleeved on the surface of the piston rod A52. Piston rods B55 are slidably connected to the inner pistons at the other two ends of the hydraulic chamber 51,At one end of the two piston rods B55 away from the hydraulic chamber 51, a clamping block 56 is fixedly connected. The insertion seat 57 is fixedly connected to the top of the turning seat 32. The insertion bar 58 is fixedly connected to the rear end of the main body 4 of the electricity meter box. The insertion bar 58 is inserted into the inside of the insertion seat 57. Locking grooves 59 are formed on both sides of the insertion bar 58. A speed reduction wheel assembly 510 is arranged on the top of the insertion seat 57. The speed reduction wheel assembly 510 includes a connecting frame 5101. The connecting frame 5101 is fixedly connected to the top of the insertion seat 57. A runner 5102 is rotatably connected to the inner side of the connecting frame 5101. An opening groove 5103 is formed on the surface of the runner 5102. An elastic rope 5104 is arranged inside the opening groove 5103. A resistance plate 5105 is elastically connected inside the opening groove 5103 through the elastic rope 5104. One end of the pressing plate 53 away from the piston rod A52 is initially in contact with the front end of the turning plate 31, and the elastic spring 54 is initially in a compressed state. One end of the two clamping blocks 56 away from the piston rod B55 is initially located in the two locking grooves 59 respectively. The side surface of the runner 5102 is initially in contact with the side surface of the insertion bar 58, and the resistance plate 5105 is initially completely inside the opening groove 5103. The two clamping blocks 56 are stuck in the two locking grooves 59, making it impossible for the insertion bar 58 to move upward and leave the insertion seat 57.,

[0038] During use, align the bottom interface of the electricity meter box main body 4 with the connecting post 33 at the top of the flipping seat 32 for insertion, and insert the rear insert bar 58 of the electricity meter box main body 4 from the top of the insertion seat 57. The conductive block 35 will enter the conductive member 9 for electrical connection, and the shielding plate 83 will retract into the opening groove 81 due to extrusion, compressing the compression spring 82. The gravity of the electricity meter box main body 4 will not cause the compression spring 82 to rebound. When the bottom interface of the electricity meter box main body 4 is separated from the connecting post 33, the compression spring 82 will rebound to drive the shielding plate 83 to bounce upward to shield and protect the conductive block 35. Then, flip the flip plate 31 and the flipping seat 32 to the vertical state, press down the lifting plate 314 to drive the insertion post 315 to move downward and insert it into the insertion slot 37, compressing the return spring 317. At first, the arc surface of the arc-shaped block 310 is squeezed by the bottom of the insertion post 315 and retracts into the groove 38, compressing the telescopic spring 39. When the insertion post 315 continues to move downward to drive the card slot 316 to coincide with the groove 38, the telescopic spring 39 will rebound to drive the arc-shaped block 310 to snap into the card slot 316. At this time, the insertion post 315 cannot move upward to leave the card slot 316, and the flip plate 31 and the flipping seat 32 are restricted and no longer flip, so as to ensure the stable use of the electricity meter box main body 4. When it is necessary to disassemble the electricity meter box main body 4, the arc-shaped block 310 can be pulled by pulling the pull rod 311 to leave the card slot 316 and retract into the groove 38. During the process of flipping the flip plate 31 and the flipping seat 32 to the vertical state, the pressing plate 53 will contact the front end of the flip plate 31 and be squeezed to move forward, squeezing the return spring 317. The forward movement of the pressing plate 53 will drive the piston rod A52 to move forward. The forward movement of the piston rod A52 will drive two piston rods B55 to move through the hydraulic pressure in the hydraulic chamber 51, so that two clamping blocks 56 snap into two locking grooves 59. The two clamping blocks 56 are stuck in the two locking grooves 59, making the insert bar 58 unable to move upward to leave the insertion seat 57, thereby locking the position of the electricity meter box main body 4. When the flip plate 31 and the flipping seat 32 are flipped downward, the return spring 317 drives the pressing plate 53 and the piston rod A52 to return. The two piston rods B55 drive the two clamping blocks 56 to leave the two locking grooves 59. At this time, the electricity meter box main body 4 can move upward to drive the insert bar 58 to leave the insertion seat 57. During the process of inserting the rear insert bar 58 of the electricity meter box main body 4 from the top of the insertion seat 57, the insert bar 58 moves downward and contacts the runner 5102 to drive the runner 5102 to rotate. When the moving speed of the insert bar 58 is relatively fast, the rotation speed of the runner 5102 also becomes faster. At this time, the centrifugal force generated by the rapid rotation of the runner 5102 will throw out the resistance plate 5105 to contact the insert bar 58. When the uneven end of the rubber resistance plate 5105 contacts the insert bar 58, it will bring greater resistance to the movement of the insert bar 58, thereby slowing down the downward movement speed of the insert bar 58 and preventing impact caused by excessive speed due to gravity.

[0039] Please refer to Figure 1-11, on the basis of the above embodiments, in another embodiment of the present invention, the one-way speed reduction mechanism 6 includes a driving gear 61, a rotating rod 62, a cross bar 66, a fixed plate 68 and a limiting rod 610. The driving gear 61 is fixedly connected to one end of the rotating shaft 36 away from the flipping seat 32. The rotating rod 62 is fixedly connected to the outside of the protection plate 2. A driven gear 63 is fixedly connected to the surface of the rotating rod 62. One end of the rotating rod 62 away from the protection plate 2 is fixedly connected to a rotating block 64. A speed reduction airbag 65 is fixedly connected to the surface of the rotating block 64. The cross bar 66, the fixed plate 68 and the limiting rod 610 are all fixedly connected to the outside of the protection plate 2. A rotating plate 67 is rotatably connected to the surface of the cross bar 66. A spring telescopic rod 69 is fixedly connected to the bottom of the fixed plate 68. The telescopic end of the spring telescopic rod 69 is fixedly connected to the rotating plate 67. One end of the rotating plate 67 away from the cross bar 66 is arc-shaped, and one end of the rotating plate 67 away from the cross bar 66 is close to the surface of the rotating block 64. When the rotating block 64 rotates, it will drive the speed reduction airbag 65 to contact the arc-shaped end of the rotating plate 67. The driving gear 61 meshes with the driven gear 63. The limiting rod 610 is close to the rotating plate 67. The speed reduction airbag 65 is integrally semi-cylindrical. The limiting rod 610 enables the rotating plate 67 to deflect only clockwise. When the speed reduction airbag 65 is squeezed by the arc-shaped end of the rotating plate 67, a large resistance will be generated.

[0040] An electric meter box includes an electric meter box main body 4. A display screen 7 is arranged at the front end of the electric meter box main body 4. An interface is opened at the bottom of the electric meter box main body 4. A conductive member 9 is arranged inside the interface.

[0041] During use, during the installation or disassembly of the electric meter box main body 4, when the flipping plate 31 and the flipping seat 32 flip downward, the rotating shaft 36 rotates clockwise following the flipping seat 32. The clockwise rotation of the rotating shaft 36 drives the driving gear 61 to rotate clockwise. The clockwise rotation of the driving gear 61 drives the driven gear 63 to rotate counterclockwise, and the rotation angle of the driven gear 63 is relatively large. The counterclockwise rotation of the driven gear 63 drives the rotating block 64 to rotate counterclockwise. The counterclockwise rotation of the rotating block 64 will drive the speed reduction airbag 65 thereon to contact the arc-shaped end of the rotating plate 67. During this process, under the limitation of the limiting rod 610, the rotating plate 67 cannot deflect and will be squeezed by the speed reduction airbag 65 to generate a large resistance, thereby slowing down the speed when the flipping plate 31 and the flipping seat 32 flip downward and preventing damage to the electric meter box main body 4 caused by too fast speed. When the flipping plate 31 and the flipping seat 32 are flipped upward, the speed reduction airbag 65 rotates clockwise following the rotating block 64 and contacts the rotating plate 67. At this time, the rotating plate 67 deflects and will not be squeezed by the speed reduction airbag 65 too much to generate a large resistance.

[0042] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
