Description

Technical Field

[0001] The invention relates to the technical field of electric energy metering boxes, and in particular to an embedded electric energy metering box. Background Art

[0002] A flush mounted energy meter box is a device used to measure and monitor electricity consumption, usually installed in a wall or ceiling to save space and maintain aesthetics. This type of meter box is mainly used in residential, commercial buildings and industrial facilities to accurately record the user's electricity consumption and provide a basis for electricity bill settlement.

[0003] In the patent with the publication number CN213989720U, a low-voltage embedded integrated metering box in the technical field of integrated metering box is disclosed, including a metering box embedded in an outer frame and a smoke sensor. This patent has a reasonable design. By embedding the metering box in the outer frame and pre-installing it in a hole excavated in the wall, the embedded outer frame fixing plate and fixing bolts are adopted to change the height and inclination of the embedded outer frame fixing plate to adapt to the size of different holes, thereby accelerating the installation speed of the metering box and improving the overall work efficiency and effect. Then, the metering box is installed inside the embedded outer frame of the metering box through the fixing block bolts and the fixing block, and the metering box is freely disassembled and installed, which facilitates the replacement and maintenance of the metering box. When leakage occurs through the smoke sensor, the alarm, the controller, and the leakage protection switch, smoke is generated. When the alarm sounds, the controller controls the leakage switch to cut off the power to avoid safety accidents. However, this embedded metering box is still fixed by multiple bolts during installation, which makes it inconvenient to install and disassemble the metering box. Moreover, the outer frame of the metering box is fixed only by the friction between the two fixing plates and the wall, and the installation stability is also poor.

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0038] Example 1

[0039] An embedded electric energy meter box, such as Figure 1-Figure 7 As shown, it includes a frame 1, an electric energy meter 11, a rotating shaft 12, a rotating block 13, a top block 14, a stop block 15, a limiting column 16, a limiting block 17, a connecting block 18, a telescopic block 1801 and a first swing rod 19. The upper and lower sides of the frame 1 are fixedly connected to the electric energy meter 11 which is symmetrically distributed on the left and right sides. The middle part of the frame 1 is rotatably connected to the rotating shaft 12, and the rotating block 13 is fixedly connected to the rear side of the rotating shaft 12. Four pairs of limiting columns 16 distributed equidistantly around the circumference are fixedly connected to the rear side of the frame 1, wherein each pair includes two limiting columns 16, and the two adjacent limiting columns 16 are fixedly connected to the rear side of the frame 1. A top block 14 is slidably connected between the limit columns 16, and the top block 14 is squeezed and matched with the rotating block 13. A stop block 15 is fixedly connected to the end of the top block 14 away from the rotating block 13, and two connecting blocks 18 are fixedly connected to the front side of the stop block 15. A telescopic block 1801 is slidably connected to the outside of the connecting block 18, and the telescopic end of the telescopic block 1801 is fixedly connected to the limit block 17, and the stop block 15 is in contact and matched with the adjacent limit block 17. The rotating block 13 is rotatably connected to four first swing rods 19 distributed equidistantly around the circumference, and the first swing rod 19 is rotatably connected to the adjacent top block 14.

[0040] like Figure 7 As shown, one end of the top block 14 close to the rotating block 13 is circular.

[0041] like Figure 5 and Figure 7 As shown, a side of the stop block 15 away from the top block 14 is provided with sawtooth stripes to increase the friction between the stop block 15 and the wall.

[0042] like Figure 5 and Figure 6 As shown, a slope is provided on the rear side of the limit block 17 .

[0043] When workers need to embed the energy meter box in the wall, they can first open a mounting hole of suitable size on the wall according to the size of the rack 1, and put the rack 1 and the energy meter 11 and other components into the mounting hole, and then they can rotate the shaft 12 clockwise, and drive the rotating block 13 to rotate clockwise, and the clockwise rotation of the rotating block 13 will squeeze the top block 14, so that the top block 14, the stop block 15 and the limit block 17 and other components on the surrounding sides all move away from the rotating block 13 and press against the wall, and the first swing arm 19 rotates immediately, so that the worker only needs to rotate the shaft 12 to make the stop block 15 press against the wall from all sides and support and fix the rack 1, so as to quickly complete the installation of the rack 1 and the energy meter 11, and when the rack 1 and the stop block 15 and other components deviate and slide forward, because the limit block 17 is at this time Under the action of the telescopic block 1801, it is tightly attached to and against the wall, so the limit block 17 and the telescopic block 1801 will remain motionless relative to the wall, and when the stop block 15 slides forward until it contacts and squeezes the limit block 17, the stop block 15 will apply a forward force and a force close to the wall to the limit block 17, thereby increasing the pressure of the limit block 17 on the wall and the friction between the limit block 17 and the wall, thereby effectively preventing the rack 1 from deviating and sliding forward in the wall, thereby improving the installation stability of this electric energy meter box. When the worker needs to remove the rack 1 and other components from the wall, he only needs to rotate the shaft 12 and the rotating block 13 counterclockwise, and drive the surrounding top blocks 14, stop blocks 15 and limit blocks 17 and other components to move in the opposite direction and reset through the first rocker arm 19, so that the rack 1 and the electric energy meter 11 can be quickly disassembled.

[0044] Example 2 On the basis of Example 1, Figure 8 and Fig. 9 As shown, a reinforcement mechanism is also included, which is arranged on the frame 1. The reinforcement mechanism includes a blocking block 2, a screw rod 21, a moving block 22, a guide plate 23, a pull frame 24 and a second swing rod 25. The two blocking blocks 2 are rotatably connected to the left and right sides of the frame 1 respectively. A screw rod 21 is fixedly connected to the middle of the rotating shaft 12. The moving block 22 is slidably connected inside the frame 1. The moving block 22 is threadedly connected to the screw rod 21. The left and right sides of the moving block 22 are fixedly connected to the guide plates 23. The guide plates 23 are slidably connected to the frame 1. The pull frames 24 are slidably connected to the adjacent guide plates 23. The end of the pull frame 24 away from the guide plate 23 is rotatably connected to the second swing rod 25. The second swing rod 25 is rotatably connected to the adjacent blocking block 2.

[0045] like Figure 8 and Fig. 9 As shown, a locking groove is provided in the middle of the pull frame 24 .

[0046] When the worker rotates the shaft 12 clockwise, the screw rod 21 will also rotate clockwise with the shaft 12, thereby driving the moving block 22 and the guide plate 23 to move backward, and the backward movement of the guide plate 23 will drive the pull frames 24 on the left and right sides to slide toward each other, and drive the blocking blocks 2 on the left and right sides to rotate and expand in the direction away from the frame 1 until they are against the walls on the left and right sides through the second swing rod 25, so that the frame 1 can be further fixed with the help of the expanded blocking blocks 2, and the frame 1 can be prevented from deflecting and sliding in the wall, thereby improving the installation stability of this electric energy metering box, and when the worker rotates the shaft 12 and the screw rod 21 counterclockwise, the moving block 22 and the guide plate 23 will move forward and reset under the action of the screw rod 21, thereby driving the pull frames 24 on the left and right sides to slide back and reset, and the pull frames 24 on the left and right sides will slide back and reset, and the second swing rod 25 will respectively drive the blocking blocks 2 on the left and right sides to rotate and reset in the opposite direction.

[0047] like Figure 10-12 As shown, a filling mechanism is also included, which is arranged on the frame 1. The filling mechanism includes a first expansion block 3, an air cylinder 31, an air guide pipe 32, a connecting frame 33 and a locking assembly. The first expansion block 3 is fixed to the front side of the outside of the frame 1, and four air cylinders 31 distributed longitudinally front and back are fixed to the left and right sides of the inside of the frame 1. The first expansion block 3 is fixed to the four air cylinders 31 distributed longitudinally front and back and are connected with the air guide pipe 32. A connecting frame 33 is fixed to the middle part of the pulling frame 24. The connecting frame 33 is slidably connected to the frame 1. The connecting frame 33 is fixed to the piston rods of the adjacent four air cylinders 31 distributed longitudinally front and back, and a locking assembly is provided on the first expansion block 3.

[0048] like Figure 10-12 As shown, the positioning assembly includes a second expansion block 34, a bracket 35 and a relief valve 36. The left and right parts of the rear side of the first expansion block 3 are fixedly connected and connected to the second expansion block 34. The rear side of the second expansion block 34 is fixedly connected to the bracket 35. The bracket 35 is slidably connected to the frame 1, and the bracket 35 is in contact with the pulling frame 24. The left and right sides of the first expansion block 3 are fixedly connected to the relief valve 36.

[0049] When the worker drives the left and right pull racks 24 to move toward each other by rotating the rotating shaft 12 clockwise, the left and right connecting racks 33 and the piston rod in the air cylinder 31 will also move toward each other with the pull rack 24, so that the gas in the air cylinder 31 is injected into the first expansion block 3 and the second expansion block 34 through the air guide pipe 32, and the first expansion block 3 will then expand and fill the gap between the rack 1 and the wall, thereby preventing dust, insects and other debris and moisture from entering and affecting the normal operation of the electric energy meter 11. At this time, since the left and right pull racks 24 move toward each other to the position slot corresponding to the adjacent bracket 35, the second expansion block 34 will also expand and squeeze the bracket 35, so that the bracket 35 moves backward and enters the position of the adjacent pull rack 24 The groove can be used to clamp the pull frame 24, thereby improving the stability and fixing effect of the blocking block 2 in disguise, and improving the installation stability of the electric energy metering box. When the worker needs to rotate the rotating shaft 12 counterclockwise, the air release valve 36 needs to be opened in advance, and the gas in the first expansion block 3 and the second expansion block 34 will be discharged from the air release valve 36, and the first expansion block 3 and the second expansion block 34 will also be deformed and contracted immediately, thereby driving the clamping frames 35 on the left and right sides to move forward and reset and separate from the pull frame 24. At this time, rotating the rotating shaft 12 counterclockwise again will drive the pull frames 24, the connecting frame 33 and the piston rod on the left and right sides to move back and reset, and suck the outside air into the air cylinder 31 through the air guide pipe 32 and the air release valve 36, and finally close the air release valve 36.

[0050] like Fig.13 and Fig.14 As shown, a resisting mechanism is also included, which is arranged on the frame 1. The resisting mechanism includes an elastic card 4, a pull rope 41 and a push block 42. The rear ends of the two elastic cards 4 are respectively fixed to the left and right sides of the lower part of the frame 1, and the end of the elastic card 4 away from the frame 1 is fixed to the push block 42. The left and right sides of the frame 1 are slidably connected with the pull rope 41. One end of the pull rope 41 is fixed to the adjacent push block 42, and the other end of the pull rope 41 is fixed to the adjacent blocking block 2.

[0051] When the blocking blocks 2 on the left and right sides are rotated and expanded in the direction away from the frame 1, the blocking blocks 2 will straighten the pull rope 41 and drive the pushing blocks 42 on the left and right sides to move backward through the pull rope 41, and the elastic cards 4 on the left and right sides will be deformed and respectively press against the lower left and right walls, thereby supporting and fixing the frame 1 to prevent the frame 1 from deflecting and sliding in the wall, thereby improving the installation stability of the electric energy meter box; when the blocking blocks 2 on the left and right sides are rotated in the opposite direction to reset, the pull rope 41 is immediately loosened, and the elastic card 4 will return to its original state under the action of its own elasticity and drive the pushing block 42 to move forward and reset.

[0052] like Figure 1 and Fig.15As shown, a supporting mechanism is also included, which is arranged on the frame 1. The supporting mechanism includes a threaded rod 5, a sleeve 51 and a push plate 52. The two threaded rods 5 are rotatably connected to the left and right sides of the frame 1 respectively. The left and right parts of the rear side of the frame 1 are slidably connected with the sleeves 51. The push plate 52 is fixed between the rear ends of the two sleeves 51. The sleeves 51 are threadedly connected to the adjacent threaded rods 5.

[0053] After the rack 1 and the electric energy meter 11 and other components are installed in the installation hole, if there is a gap between the rear side of the rack 1 and the wall, the left and right threaded rods 5 can be rotated forward synchronously, thereby driving the sleeve 51 and the push plate 52 to move backward and against the wall at the rear side, so as to fill the gap between the rear side of the rack 1 and the wall and provide support for the rack 1, thereby preventing the rack 1 from deviating and sliding backward, thereby improving the installation stability of the electric energy meter box. When not needed, the left and right threaded rods 5 can be rotated in the opposite direction synchronously, and the sleeve 51 and the push plate 52 can be driven to move forward and reset.

[0054] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
