Detailed implementation manners

[0031] The following further describes the present application in detail with reference to the accompanying drawings. It is necessary to point out here that the following specific implementation manners are only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0032] See Figures 1 - 4, A convenient dismountable watt-hour meter that can be quickly positioned and separated, including a watt-hour meter box 1, a guide rail 2, a watt-hour meter body 3, a detachable slider 4, and a convenient dismounting mechanism. The guide rails 2 are evenly spaced and connected from top to bottom inside the watt-hour meter box 1. The detachable slider 4 is slidably arranged on the guide rail 2 inside the watt-hour meter box 1. The detachable slider 4 includes an upper slider 41 and a lower slider 42, and the upper slider 41 and the lower slider 42 are connected by bolts for the quick disassembly and assembly of the detachable slider 4. The watt-hour meter body 3 is connected to the detachable slider 4 through a convenient dismounting mechanism. The convenient dismounting mechanism includes an annular plate 51 connected to the back of the watt-hour meter body 3. Two sets of insertion rods 52 are connected to the back of the annular plate 51. The number of insertion rods 52 in each set is two, and the two insertion rods 52 in each set are symmetrically arranged left and right. A set of insertion holes 53 matching the insertion rods 52 are opened on both the upper slider 41 and the lower slider 42. Two insertion holes 53 form a set, and the two insertion holes 53 are symmetrically arranged left and right. A card slot 54 is opened on the upper insertion rod 52. A set of latch blocks 55 matching the card slot 54 are hinged to the upper part of the upper slider 41. The number of latch blocks 55 is two, and the two latch blocks 55 are symmetrically arranged left and right. The bottom of the latch block 55 is designed with an inclined surface, and the front side of the card slot 54 is designed with an inclined surface to adapt to the latch block 55 with an inclined surface design. When the upper insertion rod 52 is inserted into the upper insertion hole 53, the inclined surface at the bottom of the latch block 55 is squeezed to push the latch block 55 to rotate upward to avoid the upper insertion rod 52, so there is no need to manually rotate the latch block 55 upward to avoid the upper insertion rod 52, which is more convenient for the installation of the watt-hour meter. A handle 56 is connected between the tops of the two latch blocks 55. A set of friction blocks 57 are hinged to the upper part of the upper slider 41. The friction blocks 57 are located below the latch blocks 55. The number of friction blocks 57 is two, and the two friction blocks 57 are symmetrically arranged left and right. A pulling component is provided between the friction block 57 and the latch block 55 directly above it. After the upper insertion rod 52 is inserted into the upper insertion hole 53, it presses the friction block 57 to keep the friction block 57 in contact with the guide rail 2, thereby improving the connection stability between the detachable slider 4 and the guide rail 2 to prevent the detachable slider 4 from sliding randomly. A rubber block for increasing the friction with the guide rail 2 is connected to the bottom of the friction block 57. The friction block 57 pulls the latch block 55 through the pulling component to firmly lock the upper insertion rod 52. The pulling component includes two fixed pulleys 58 respectively connected to the left and right sides of the latch block 55. A first pulling rope 59 is connected to both the left and right sides of the friction block 57. The two first pulling ropes 59 respectively bypass the two fixed pulleys 58, and a tension spring 510 is connected between the first pulling rope 59 and the upper slider 41.

[0033] First, install the detachable slider 4 on the guide rail 2 inside the watt-hour meter box 1. Then, horizontally move the detachable slider 4 horizontally according to the circuit layout to adjust the position of the detachable slider 4, so as to realize the horizontal adjustment of the watt-hour meter body 3, thereby improving the flexibility of installation to meet the requirements of different circuit layouts. Then, move the watt-hour meter body 3 backward to insert the insertion rod 52 backward into the insertion hole 53. The upper insertion rod 52 is inserted between the clamping block 55 and the friction block 57 accordingly. When the upper insertion rod 52 is inserted into the upper insertion hole 53, it squeezes the inclined surface at the bottom of the clamping block 55 to push the clamping block 55 to rotate upward to avoid the upper insertion rod 52. When the upper insertion rod 52 is inserted into the upper insertion hole 53, it presses the friction block 57 to keep the friction block 57 in contact with the guide rail 2, thereby improving the connection stability between the detachable slider 4 and the guide rail 2 to prevent the detachable slider 4 from sliding randomly. The upward rotation of the clamping block 55 drives the fixed pulley 58 to move upward, so that the pulling rope 59 pulls the tension spring 510. When the clamping groove 54 on the upper insertion rod 52 moves to align with the inclined surface of the clamping block 55, under the reset action of the tension spring 510, the pulling rope 59 is pulled downward, so as to pull the fixed pulley 58 to drive the clamping block 55 to rotate downward and snap into the clamping groove 54 to lock the upper insertion rod 52, thereby locking the watt-hour meter body 3 on the detachable slider 4. And because the friction block 57 is pressed by the upper insertion rod 52, the friction block 57 pulls the fixed pulley 58 through the pulling rope 59, so as to be able to pull the clamping block 55 to ensure that the clamping block 55 stably locks the upper insertion rod 52, and then the watt-hour meter body 3 can be stably locked on the front of the detachable slider 4. The method of locking the watt-hour meter body 3 on the front of the detachable slider 4 does not occupy lateral space, improves the space utilization rate, and can increase the installation quantity of watt-hour meters. Manually pull the handle 56 upward, and the clamping block 55 can be driven to rotate upward and disengage from the upper insertion rod 52, thereby unlocking the watt-hour meter body 3. Then, the watt-hour meter body 3 can be removed from the detachable slider 4. In this way, moving the watt-hour meter body 3 backward can lock the watt-hour meter body 3 on the detachable slider 4 through the convenient disassembly and assembly mechanism, and pulling the handle 56 upward can make the clamping block 55 rotate upward to unlock the watt-hour meter body 3, realizing the convenient disassembly and assembly of the watt-hour meter body 3.

[0034] If multiple watt-hour meter bodies 3 are disassembled at one time, with the maintenance operation of the maintenance personnel, it is easy to forget the original positions of the watt-hour meter bodies 3, resulting in the wrong connection positions of the watt-hour meter bodies 3, affecting the normal counting of the user's electric energy. In a preferred embodiment, refer to Figures 5 - 6, in order to avoid the situation where the electricity meter body 3 is wrongly connected, an anti-misplugging mechanism is provided between the electricity meter body 3 and the detachable slider 4. The anti-misplugging mechanism includes a plug 6, a socket 7, a fastening bolt 8 and a locking member. The plug 6 is inserted into the socket 7. The plug 6 includes a circular plate 61. Three insertion rods 62 are evenly spaced circumferentially on the back of the circular plate 61. Three guide blocks 63 are evenly spaced circumferentially on the back of the circular plate 61. The guide blocks 63 are located between every two adjacent insertion rods 62. A connecting rod 64 is connected to the guide block 63. Two groups of thin sheets 65 are connected to the connecting rod 64. The number of each group of thin sheets 65 is two. The two thin sheets 65 in each group are symmetrically distributed with respect to the connecting rod 64. The plug 6 is located inside the annular plate 51. The circular plate 61 is connected to the back of the electricity meter body 3 through the fastening bolt 8. The socket 7 includes a socket base 71. Three insertion holes 72 matching the insertion rods 62 are evenly spaced circumferentially on the socket base 71. Three guide grooves 73 matching the guide blocks 63 are evenly spaced circumferentially on the socket base 71. The guide grooves 73 are located between every two adjacent insertion holes 72. The end of the thin sheet 65 away from the connecting rod 64 is connected in the guide groove 73. There is a through hole 74 in the middle of the socket base 71 for a finger to reach in and turn the fastening bolt 8. The plug 6 and the socket 7 are integrally injection-molded from plastic. A locking member for locking the socket base 71 is provided on the front of the detachable slider 4. The locking member includes an annular seat 81 connected to the fronts of the upper slider 41 and the lower slider 42. The annular seat 81 is located between the four jacks 53. Four fastening bolts 82 for locking the socket base 71 are evenly spaced circumferentially on the annular seat 81.

[0035] Randomly install the plug 6 on the back of the electricity meter body 3 through the fastening bolt 8. When the electricity meter body 3 is installed backward on the detachable slider 4, the socket 7 is driven to move backward into the annular seat 81 by the plug 6. When the socket 7 moves to contact the detachable slider 4, the socket 7 cannot move backward continuously. Thus, the electricity meter body 3 drives the plug 6 to continue moving backward, breaking the thin sheet 65 on the plug 6 and releasing the lock between the plug 6 and the socket 7. The insertion rod 62 then slides in the insertion hole 72, and the guide block 63 slides in the guide groove 73. Tighten the fastening bolt 82 to lock the socket 7 on the front of the detachable slider 4. When the electricity meter body 3 is removed, it drives the plug 6 to be pulled out forward from the socket 7. Since the plug 6 is randomly installed on the back of the electricity meter body 3 through the fastening bolt 8, the positions of the three insertion rods 62 on the plug 6 and the three corresponding insertion holes 72 on the socket 7 are in one-to-one correspondence, and the positions of the three guide blocks 63 on the plug 6 and the three corresponding guide grooves 73 on the socket 7 are in one-to-one correspondence. Therefore, only the plug 6 and the socket 7 at the corresponding same positions can be plugged in subsequently, so as to ensure that the electricity meter body 3 is accurately installed back on the corresponding detachable slider 4 to avoid the wrong connection of the electricity meter body 3 affecting the normal counting of the user's electricity.

[0036] After the electricity meter body 3 is removed, during the process of picking it up and placing it, one-handed operation may be involved. Since it is unstable to control the electricity meter body 3 with one hand, it may cause accidental falling and impact damage on the ground. In a preferred embodiment, refer to Figures 7 - 9 , in order to avoid the situation where the electricity meter body 3 falls and impacts the ground, a dropping mechanism is provided between the electricity meter body 3 and the detachable slider 4. The dropping mechanism includes a mounting seat 91 embedded in the upper part of the back surface of the electricity meter body 3. A wire wheel 92 is rotatably connected in the mounting seat 91. A volute spring 93 is connected between the wire wheel 92 and the mounting seat 91. The top of the upper slider 41 is connected with a detachable connecting rod 94. The detachable connecting rod 94 includes an outer rod 941 connected to the top of the upper slider 41. An inner rod 942 is inserted into the outer rod 941. Two positioning rods 943 are circumferentially and spacedly connected to the inner rod 942. Two hook grooves 944 for hooking the positioning rods 943 are circumferentially and spacedly formed on the outer rod 941. The hook groove 944 is composed of a long vertical section, a horizontal section and a short vertical section. A support spring 945 is arranged in the outer rod 941. The support spring 945 abuts against the outer rod 941 and the inner rod 942. A second pull rope 95 is connected to the inner rod 942. The second pull rope 95 is wound around the wire wheel 92 and fixedly connected to the wire wheel 92.

[0037] During the process of removing and taking away the electricity meter body 3, the mounting seat 91 drives the wire wheel 92 to move, pulls out the second pull rope 95, and the wire wheel 92 rotates accordingly to release the pull rope. The volute spring 93 is compressed accordingly. The second pull rope 95 can hold the electricity meter body 3 to avoid damage caused by the electricity meter body 3 falling and impacting the ground when it is unstable to control the electricity meter body 3 with one hand, thereby improving safety. During the process of reinstalling the electricity meter body 3, the mounting seat 91 drives the wire wheel 92 to move back to its original position. Under the reset action of the volute spring 93, the wire wheel 92 rotates in the reverse direction to wind up the second pull rope 95 to keep the second pull rope 95 neat and avoid scattering. Press down the inner rod 942 to drive the positioning rod 943 to move down into the horizontal section of the hook groove 944, and then rotate the inner rod 942 to drive the positioning rod 943 to rotate into the long vertical section of the hook groove 944. Under the reset action of the support spring 945, the inner rod 942 can be pushed to move the positioning rod 943 upward out of the long vertical section of the hook groove 944 to release the locking of the inner rod 942, thereby facilitating the subsequent replacement of the electricity meter body 3. Move down the inner rod 942 to insert the positioning rod 943 into the horizontal section of the hook groove 944 through the long vertical section of the hook groove 944. The support spring 945 is compressed accordingly. Then rotate the inner rod 942 to drive the positioning rod 943 to rotate into the short vertical section of the hook groove 944. Under the supporting action of the support spring 945, the inner rod 942 drives the positioning rod 943 to move upward and lock in the short vertical section of the hook groove 944, thereby locking the inner rod 942 and further locking the second pull rope 95 on the detachable slider 4 to realize the anti-falling impact protection of the electricity meter body 3.

[0038] See Figure 10 , a button 10 is installed at the lower part of the front surface of the lower slider 42. The button 10 is located between the two lower jacks 53. A connecting plate 11 is connected to the upper part of the back surface of the upper slider 41. An indicator light 12 is installed on the connecting plate 11. The indicator light 12 is electrically connected to the button 10. A pressing rod 13 for pressing the button 10 is connected to the lower part of the back surface of the annular plate 51. The pressing rod 13 is located between the two lower inserting rods 52.

[0039] After the electricity meter body 3 is installed on the detachable slider 4, the pressing rod 13 presses the button 10 to turn on the indicator light 12, and the indicator light 12 lights up accordingly, so that the installer can visually confirm whether the electricity meter body 3 has been correctly installed in place.

[0040] The above embodiments only represent the preferred embodiments of the present invention, and the description thereof is relatively specific and detailed. However, it should not be construed as a limitation to the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several variations, improvements and substitutions can still be made, and these all belong to the protection scope of the present invention.
