[0003] Traditional energy meter installation methods typically use screws, making installation and removal cumbersome and time-consuming. This method is particularly inefficient and inconvenient when meters need to be frequently replaced or inspected. Furthermore, traditional mounting structures lack stability and safety, making meters prone to shaking or falling off during installation, impacting performance and safety. Summary of the Invention

The locking structure controls the locking state of the connecting locking mechanism in the electric energy meter pendant by abutting against the push-pull mechanism. The limiting structure is used to switch the locking state of the locking structure. When the push-pull mechanism moves downward, it will abut against the locking structure so that the connecting locking mechanism is fixedly locked in the electric energy meter pendant. When the push-pull mechanism moves upward, the locking structure is kept fixedly locked through the limiting structure until the connecting locking mechanism moves to the uppermost end of the installation slot and switches the locking state through the limiting structure, so that the connecting locking structure can be detachably locked in the electric energy meter pendant.

When the folding rod moves to the right, the hanging rod slides into the hanging groove to limit the folding rod so that the connection locking mechanism remains fixed and locked. When the support plate connecting block moves upward until the upper end of the rotating pull rod hits the upper wall of the installation groove, the rotating pull rod drives the hanging rod to move upward to release the limit of the folding rod and switch the connection locking mechanism to a detachable lock.

[0010] Preferably, a base is provided in the plug at a position corresponding to the left side of the push bead, an opening is provided in the middle of the base, a push rod is provided on the left side of the base, the right end of the push rod can pass through the opening, a spring is sleeved on the outer peripheral surface of the right end of the push rod, one end of the spring is connected to the base, and the other end is connected to the connecting rod, so that the push rod can be restored to its original position through the spring.

[0013] Preferably, a meter withdrawal protrusion is provided at a position on one side of the support plate corresponding to the upper portion of the back plate. When the electric energy meter moves up to the position of the meter withdrawal protrusion, the electric energy meter is blocked and stops moving up, and the connection locking mechanism has not reached the top of the installation slot. The electric energy meter continues to move up by pushing the grip rod, thereby releasing the limit of the folding rod of the limiting structure.

The lower end of the rack rack is fixed to the pressing sleeve, and a locking rod is arranged on the lower side of the pressing sleeve. A locking rod pushes a spring in the pressing sleeve, and the gear drives the rack rack to move downward by rotating the push-pull handle, and the rack rack drives the pressing sleeve and the locking rod to move downward synchronously, pressing down the electric energy meter power terminal to ensure a firm connection with the electric energy meter connection socket.

[0016] The present invention further discloses a control method for an electric energy meter installation device, based on an electric energy meter installation device according to any one of claims 1 to 9, characterized in that:

[0018] When the push-pull mechanism moves downward, the connection locking mechanism moves downward synchronously, and the connection locking structure is fixedly locked in the electric energy meter pendant through the locking structure, and the limiting structure keeps the locking structure fixedly locked;

[0019] When the push-pull mechanism moves upward, the connecting locking mechanism moves upward synchronously, and the locking structure is restricted by the limiting structure and remains fixedly locked until the support plate connecting block moves to the uppermost end of the mounting slot and switches the locking state, so that the connecting locking structure can be removably locked in the electric energy meter pendant.

[0020] The beneficial effect of the present invention is that, compared with the prior art,

[0021] The present invention controls the up and down movement of the connecting locking mechanism through a push-pull mechanism, thereby realizing rapid installation and removal of the electric energy meter. The electric energy meter can be fixed and removed only by pushing and pulling the grip rod, which greatly improves the installation and removal efficiency, saves labor costs and time costs, simplifies the installation and removal process, is suitable for occasions where the electric energy meter needs to be replaced frequently, and saves space.

[0022] When the electric energy meter is installed, the connection locking mechanism is driven downward by the push-pull mechanism, and the horizontal push rod is pressed against the folding rod, so that the top rod passes through the top beads, and the plug is fixedly locked in the electric energy meter pendant through the top beads, ensuring the stability and safety of the electric energy meter installation process, and preventing the electric energy meter from shaking during movement and docking, which may cause the electric energy meter to fall out. At the same time, the limiting structure limits and fixes the folding rod, so that after the electric energy meter is installed, the plug is always fixedly locked in the electric energy meter pendant, ensuring the stability and safety of the electric energy meter during operation and use, and preventing the electric energy meter from being detached due to vibration during operation, affecting the lives of people around it; when the electric energy meter is disassembled When the breaker is in the process of moving, the plug is locked in the electric meter pendant, so that the electric meter can be prevented from falling off due to shaking during the upward movement, thereby improving the safety performance of disassembly. Until the support plate connecting block moves to the uppermost end of the installation slot, the limiting structure releases the limiting top rod of the folding rod and retracts the top rod, and the magnet makes the top bead still extend from the plug, so that the connecting locking mechanism can be detachably locked in the electric meter pendant, further preventing the electric meter from falling off directly and avoiding damage to the electric meter caused by the difficulty of staff to react during the disassembly process.

[0023] The present invention adjusts the locking state of the connection locking mechanism through the cooperation of the locking structure and the limiting structure in the connection locking mechanism, so that the electric energy meter is fixedly locked during the up and down movement and use. On the one hand, it avoids the electric energy meter from falling off due to large shaking during the movement and docking process, improves the safety of the installation and removal of the electric energy meter, simplifies the installation and removal process, and on the other hand ensures the stability and safety of the connection of the electric energy meter during use.

[0024] The present invention is provided with a design of a meter withdrawal protrusion. During the disassembly process, the electric energy meter does not need to be manually moved, but can be automatically detached from the plug by simply moving it upward, which further simplifies the disassembly operation and reduces the operating difficulty. The detachment time of the electric energy meter is accurately controlled by the meter withdrawal protrusion, thereby improving the installation and maintenance efficiency of the electric energy meter.

[0025] An elastic column is provided on the upper end surface of the support plate of the present invention, which will support the upper wall of the back plate groove. The elastic force of the elastic column makes the installation and disassembly of the support plate more convenient. At the same time, when there is external impact and vibration, the elastic column can buffer and absorb shock, thereby improving the stability of the connection between the support plate and the back plate.

[0026] The power connection locking structure of the present invention rotates the push-pull handle to allow the locking rod to pass through the bracket and press down the power connection terminal of the electric energy meter, so that the power connection column on the electric energy meter connection socket and the power connection terminal of the electric energy meter are connected more tightly and stably, avoiding poor power supply quality caused by poor contact. The operation is simple and the use is convenient, and the power supply quality and stability are improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0041] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments described in this application are only part of the embodiments of the present invention, not all of them. Based on the spirit of the present invention, other embodiments obtained by ordinary technicians in this field without making creative efforts are all within the scope of protection of the present invention.

[0042] like Figures 1-13 As shown, the present invention provides an electric energy meter installation device, which includes: a back plate 1, a support plate 2, a connecting and locking mechanism 7 and an electric energy meter hanger 8. A groove is provided on the upper front portion of the back plate 1, the support plate 2 is installed in the groove, a lower pressure plate 6 is provided on the right side of the upper end of the support plate 2, and a mounting groove 11 passing through the support plate 2 and the back plate 1 is provided at the same position above the support plate 2 and the back plate 1. The front of the connecting and locking mechanism 7 passes through the mounting groove 11 and is plugged into the electric energy meter hanger 8, and the back side is connected to the push-pull mechanism 5, and the electric energy meter hanger 8 is connected to the back side of the electric energy meter.

[0043] like Figure 3The rear side of the back plate 1 is provided with a push-pull mechanism 5 for pushing and pulling the connecting locking structure 7. The push-pull mechanism 5 includes: a rotating rod 51, which is movably arranged on the left and right sides of the back plate 1, and the rotating rod 51 includes: a straight section 511 and an inclined section 512. The lower end of the straight section 511 is connected to the inclined section 512, and the lower end of the inclined section 512 is rotatably arranged on the side wall of the back plate 1

[0044] like Figure 4-Figure 6 As shown, the connection locking mechanism 7 has a built-in limiting structure and a locking structure. The limiting structure is arranged on the upper side of the locking structure. The locking structure controls the locking state of the connection locking mechanism 7 in the electric energy meter hanger 8 by abutting against the push-pull mechanism 5. The limiting structure is used to switch the locking state of the locking structure. When the push-pull mechanism 5 moves downward, it will abut against the locking structure so that the connection locking mechanism 7 is fixedly locked in the electric energy meter hanger 8. When the push-pull mechanism 5 moves upward, the locking structure is kept fixedly locked through the limiting structure until the connection locking mechanism 7 moves to the uppermost end of the mounting groove 11 to switch the locking state, so that the connection locking structure 7 can be detachably locked in the electric energy meter hanger 8.

[0045] The locking structure includes: a support plate connecting block 70, the support plate connecting block 70 is arranged inside the mounting groove 11, a plug 72 is provided at the lower end of the support plate connecting block 70 close to the support plate 2, a plurality of top beads 77 are symmetrically provided on the right peripheral surface of the plug 72, a base 713 is provided at the left side of the corresponding top bead 77 inside the plug 72, an opening is provided in the middle of the base 713, a push rod 74 is provided at the left side of the corresponding base 713 inside the plug 72, the shape and size of the opening on the push rod 74 and the base 713 are adaptively matched, and the push rod The right end of 74 can pass through the opening on the base 713, and the left end of the ejector rod 74 passes through the inside of the connecting rod 73 and is connected to the folding rod 76. The connecting rod 73 is a cylinder with a diameter larger than that of the ejector rod 74. The setting of the connecting rod 73 further prevents the ejector rod 74 from being offset when it moves laterally, thereby improving the stability of the locking structure in switching the locked state. A spring 75 is sleeved on the outer peripheral surface of the right side of the ejector rod 74. One end of the spring 75 is connected to the base 713 and the other end is connected to the end surface of the connecting rod 73. The spring 75 is used to restore the ejector rod 74 to its original position.

[0046] like Figure 5As shown, a guide groove 715 is provided inside the support plate connecting block 70, and a folding rod 76 is provided in the guide groove 715. The folding rod 76 is a right-angle structure, and the left end of the folding rod 76 is an inclined surface and is provided in the waist-shaped hole 71. A guide rod 714 is provided on the right side of the guide groove 715, and the guide rod 714 passes through the folding rod 76 and is slidably connected to the folding rod 76. The vertical displacement of the folding rod 76 is limited by the guide rod 714, so that the folding rod 76 can only move horizontally, avoiding displacement when the top rod 74 moves; the horizontal push rod 55 on the push-pull mechanism 5 passes through the waist-shaped hole 71, and the entire connection locking mechanism 7 is driven to move through the horizontal push rod 55, thereby driving the electric energy meter to move synchronously.

[0047] like Figure 6 As shown, magnets 79 of the same pole are provided on the opposite side of the top bead 77. The magnets 79 repel each other to generate a repulsive force, thereby causing the top bead 77 to always extend from the outer surface of the plug 72. At the same time, a frustum 78 is provided on the inner end surface of the top bead 77 to prevent the top bead 77 from falling out of the plug 72. The small end surface of the frustum 78 faces inward, and the large end surface faces outward. When the push rod 74 moves to the right, it will abut against the inclined surface of the frustum 78, making it convenient for the push rod 74 to push the top bead 77 out.

[0048] like Figure 4 、 Figure 7 and Figure 8 As shown, an electric energy meter hanger 8 is provided at the top of the back of the electric energy meter, and the electric energy meter hanger 8 includes: a hanger plate 81, a through hanging hole 82 is provided on the hanger plate 81, and the hanging hole 82 is a rectangular hole. The hanging hole 82 and the plug 72 are adaptively matched in shape. By inserting the plug 72 into the hanging hole 82 on the electric energy meter hanger 8, the electric energy meter is fixed on the front side of the support plate 2. A blocking edge 83 is provided on the inner peripheral surface of the hanging hole 82, and the blocking edge 83 is used to clamp the top bead 77 to further prevent the plug 72 from falling off from the hanging hole 82.

[0049] like Figure 5 As shown, a limiting structure is provided on the upper part of the folding rod 76, and a hanging groove 710 is provided at the left end of the folding rod 76. The limiting structure includes: a hanging rod 711 and a rotating pull rod 712. A hanging rod 711 is provided on the upper side of the folding rod 76 corresponding to the inside of the support plate connecting block 70, and a rotating pull rod 712 is provided on the upper end of the hanging rod 711. The lower end of the rotating pull rod 712 obliquely passes through the support plate connecting block 70 and is screwed to the hanging rod 711, and the upper end of the rotating pull rod 712 extends from the outer wall of the support plate connecting block 70.

[0050] In a specific embodiment, the electric energy meter is connected to the electric energy meter hanger 8, the upper end of the electric energy meter is pressed against the lower side of the lower pressure plate 6 so that the hanging hole 82 is aligned with the plug 72, and the electric energy meter is pressed inward so that the plug 72 is inserted into the hanging hole 82. The mutual repulsion of the magnet 79 causes the top bead 77 to extend from the plug 72, and the plug 72 and the electric energy meter hanger 8 are initially detachably locked; then the grip 52 is pulled downward to drive the horizontal push rod 55 to move downward, so that the horizontal push rod 55 presses the folding rod 76 in the waist-shaped hole 71, and the folding rod 76 is restricted by the guide rod 714 and moves toward the right, and the right end of the push rod 74 passes through the base 713 and is pushed out from between the top beads 77, so that all the top beads 77 are further extended from the plug 72, and the push rod The squeezing force of 74 fixes the top bead 77, and the top bead 77 cannot be retracted, thereby fixing the plug 72 in the hanging hole 82 of the electric energy meter hanger 8, thereby preventing the electric energy meter from shaking during the downward movement and causing the electric energy meter to fall, until the electric energy meter is moved down and plugged into the electric energy meter connecting socket 3 on the lower side; during the downward movement, the folding rod 76 is squeezed and moved to the right, and the hanging groove 710 moves to the right synchronously until it is at the lower end position of the hanging rod 711, and the hanging rod 711 is inserted into the hanging groove 710, thereby locking the position of the folding rod 76, so that after the electric energy meter is moved down and plugged in, the plug 72 is always fixedly locked in the hanging hole 82, so that the electric energy meter is fixed on the support plate 2, thereby improving the stability and safety of the electric energy meter after mobile installation and fixation;

[0051] When the electric energy meter is removed, the gripping rod 52 is pushed upward, and the connecting locking mechanism 7 drives the electric energy meter to move upward along the installation slot 11 and separate from the electric energy meter connecting seat 3. The folding rod 76 does not move under the restriction of the hanging rod 711, so that the plug 72 is always fixedly locked in the hanging hole 82, avoiding that the electric energy meter is directly detached when being removed, which makes it difficult for the staff to react and cause damage to the electric energy meter. Until the connecting locking mechanism 7 moves to the top of the installation slot 11, the rotating pull rod 712 is squeezed by the inner wall of the installation slot 11, so that the rotating pull rod 712 moves toward the inside of the support plate connecting block 70, driving the hanging rod 711 to lift, releasing the restriction of the hanging rod 711 on the folding rod 76, and the top rod 74 moves toward the left side under the elastic force of the spring 75, releasing the restriction on the top ball 77. The top ball 77 always extends out of the plug 72 under the mutual repulsive force of the magnet 79, so that the connecting locking mechanism 7 can be detachably locked on the electric energy meter hanging piece 8, further preventing the electric energy meter from falling off directly, thereby improving the stability and safety of the installation and removal of the electric energy meter.

[0052] like Figure 2 、 Figure 9 and Figure 10As shown, a meter withdrawal protrusion 9 is provided at a position on one side of the support plate 2 at the top of the back plate 1. When the electric energy meter moves up to the position of the meter withdrawal protrusion 9, the electric energy meter is blocked and stops moving up. At this time, there is an angle between the top of the rotating rod 51 and the back plate 1, and the connection locking mechanism 7 has not reached the top of the installation slot 11. By pushing the rotating rod 51, the electric energy meter continues to move up, and the connection locking mechanism 7 is moved to the top of the installation slot 11. The folding rod 76 releases the restriction of the limiting structure, and the electric energy meter will be squeezed by the meter withdrawal protrusion 9. The squeezing force of the meter withdrawal protrusion 9 overcomes the mutual repulsion of the magnet 79 to move the electric energy meter outward, and the electric energy meter pendant 8 will be detached from the plug 72. There is no need for the staff to manually unplug the electric energy meter, which simplifies the work process. The detachment time of the electric energy meter is accurately controlled by the meter withdrawal protrusion 9, which is convenient for the staff to operate and improves the installation and maintenance efficiency of the electric energy meter.

[0053] like Figure 9 As shown, an elastic column 10 is provided on the upper end surface of the support plate 2, and the elastic column 10 will support the upper wall of the groove of the back plate 1. The elastic column 10 is a cylindrical structure and a spring is sleeved on the outer peripheral surface. The elastic force of the elastic column 10 makes the installation and disassembly of the support plate 2 more convenient. At the same time, when there are external shocks and vibrations, the elastic column 10 can buffer and absorb shock, thereby improving the stability of the connection between the support plate 2 and the back plate 1. At the same time, when the electric energy meter moves to the top of the installation slot 11, it will squeeze the elastic column 10, and the elastic force of the elastic column 10 will push the support plate 2 to return to its original position under pressure, so that the push-pull mechanism 5 and the support plate 2 are reset to their initial state.

[0054] like Figure 11 and Figure 12 As shown, the power connection locking structure 4 is used to replace the existing power connection terminal of the electric energy meter that is tightened by screws. The power connection locking structure 4 is arranged on the lower side of the back plate 1 corresponding to the position above the electric energy meter connection socket 3; the power connection locking structure 4 includes: a bracket 41, a support 42, a shaft 43, a push-pull handle 44, a turntable 45, a gear 46, a rack rack 47, a rack 48, a pressing sleeve 49 and a locking rod 410. The bracket 41 is a door-shaped structure. Both ends of the bracket 41 are mounted on the back plate 1 by screws. Multiple brackets 42 are integrally arranged on the bracket On the upper side of 41, the shaft 43 passes through multiple supports 42 for fixation, the turntable 45 is rotatably set on the shaft 43, one side of the push-pull handle 44 is connected to multiple turntables 45, the gear 46 is set on the side of the turntable 45, and the rack rack 47 is set on the side of the gear 46. The rack rack 47 is an annular belt structure, and the rack rack 47 is provided with a rack 48 on the side facing the gear 46. One side of the rack 48 is engaged with the outer peripheral surface of the gear 46. The lower end of the rack rack 47 is fixed to the pressing sleeve 49, and the locking rod 410 is set on the lower side of the pressing sleeve 49.

[0055] In a specific embodiment, the connecting post on the electric energy meter connection socket 3 passes through the connecting terminal of the electric energy meter, so that the connecting terminal and the connecting post are in contact. By rotating the push-pull handle 44, the turntable 45 is driven to rotate, and the turntable 45 drives the gear 46 to rotate synchronously. The gear 46 pushes the rack rack 47 engaged with it to move downward, and the rack rack 47 drives the pressing sleeve 49 and the locking rod 410 to move downward synchronously. The locking rod 410 passes through the bracket 41 and presses down the connecting terminal of the electric energy meter, so that the connecting post on the electric energy meter connection socket 3 and the connecting terminal of the electric energy meter are connected more tightly and stably, avoiding poor contact and poor power quality.

[0056] Furthermore, a locking rod pushing spring is provided inside the pressing sleeve 49 so that the locking rod 410 has downward pressure after being pressed down to contact the power meter terminal, thereby ensuring that all the locking rods 410 press the power terminal firmly.

[0057] Preferably, the present invention can be used for electric energy meter detection, and the electric energy meter can be quickly plugged in and out through the electric energy meter installation device. It can also be used in an electric energy meter box to improve the disassembly and assembly effect and application quality of the electric energy meter in the existing electric energy meter box.

[0058] The present invention provides a control method for an electric energy meter installation device, comprising the following steps:

[0059] Step 1: The support plate 2 is installed in the groove on the back plate 1, the electric energy meter is connected to the electric energy meter connection socket 3, the front of the connection locking mechanism 7 passes through the installation groove and is plugged into the electric energy meter pendant 8, and the back is connected to the push-pull mechanism 5 through the waist-shaped hole 71;

[0060] Step 2: When the push-pull mechanism 5 moves downward, the connection locking mechanism 7 moves downward synchronously, and the connection locking structure 7 is fixedly locked in the electric energy meter pendant 8 by the locking structure, and the limiting structure keeps the locking structure fixedly locked;

[0061] Step 3: When the push-pull mechanism 5 moves upward, the connecting locking mechanism 7 moves upward synchronously. The locking structure is restricted by the limiting structure and remains fixedly locked until the support plate connecting block 70 moves to the uppermost end of the mounting slot 11 and switches to the locking state, so that the connecting locking structure 7 can be removably locked in the electric energy meter pendant 8.

[0062] The beneficial effect of the present invention is that, compared with the prior art,

[0063] The present invention controls the up and down movement of the connecting locking mechanism through a push-pull mechanism, thereby realizing rapid installation and removal of the electric energy meter. The electric energy meter can be fixed and removed only by pushing and pulling the grip rod, which greatly improves the installation and removal efficiency, saves labor costs and time costs, simplifies the installation and removal process, is suitable for occasions where the electric energy meter needs to be replaced frequently, and saves space.

[0064] When the electric energy meter is installed, the connection locking mechanism is driven downward by the push-pull mechanism, and the horizontal push rod is pressed against the folding rod, so that the top rod passes through the top beads, and the plug is fixedly locked in the electric energy meter pendant through the top beads, ensuring the stability and safety of the electric energy meter installation process, and preventing the electric energy meter from shaking during movement and docking, which may cause the electric energy meter to fall out. At the same time, the limiting structure limits and fixes the folding rod, so that after the electric energy meter is installed, the plug is always fixedly locked in the electric energy meter pendant, ensuring the stability and safety of the electric energy meter during operation and use, and preventing the electric energy meter from being detached due to vibration during operation, affecting the lives of people around it; when the electric energy meter is disassembled When the breaker is in the process of moving, the plug is locked in the electric meter pendant, so that the electric meter can be prevented from falling off due to shaking during the upward movement, thereby improving the safety performance of disassembly. Until the support plate connecting block moves to the uppermost end of the installation slot, the limiting structure releases the limiting top rod of the folding rod and retracts the top rod, and the magnet makes the top bead still extend from the plug, so that the connecting locking mechanism can be detachably locked in the electric meter pendant, further preventing the electric meter from falling off directly and avoiding damage to the electric meter caused by the difficulty of staff to react during the disassembly process.

[0065] The present invention adjusts the locking state of the connection locking mechanism through the cooperation of the locking structure and the limiting structure in the connection locking mechanism, so that the electric energy meter is fixedly locked during the up and down movement and use. On the one hand, it avoids the electric energy meter from falling off due to large shaking during the movement and docking process, improves the safety of the installation and removal of the electric energy meter, simplifies the installation and removal process, and on the other hand ensures the stability and safety of the connection of the electric energy meter during use.

[0066] The present invention is provided with a design of a meter withdrawal protrusion. During the disassembly process, the electric energy meter does not need to be manually moved, but can be automatically detached from the plug by simply moving it upward, which further simplifies the disassembly operation and reduces the operating difficulty. The detachment time of the electric energy meter is accurately controlled by the meter withdrawal protrusion, thereby improving the installation and maintenance efficiency of the electric energy meter.

[0067] An elastic column is provided on the upper end surface of the support plate of the present invention, which will support the upper wall of the back plate groove. The elastic force of the elastic column makes the installation and disassembly of the support plate more convenient. At the same time, when there is external impact and vibration, the elastic column can buffer and absorb shock, thereby improving the stability of the connection between the support plate and the back plate.

[0068] The power connection locking structure of the present invention rotates the push-pull handle to allow the locking rod to pass through the bracket and press down the power connection terminal of the electric energy meter, so that the power connection column on the electric energy meter connection socket and the power connection terminal of the electric energy meter are connected more tightly and stably, avoiding poor power supply quality caused by poor contact. The operation is simple and the use is convenient, and the power supply quality and stability are improved.
