Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.

[0023] Referring to Figures 1-5 A kind of adjustable angle wall-mounted installation structure of electric energy meter, including electric energy meter cabinet body 1, electric energy meter body 2, at least one set of adjusting assembly is equipped between electric energy meter cabinet body 1 and electric energy meter body 2 for connecting electric energy meter body 2 on electric energy meter cabinet body 1;Adjusting assembly includes fixed knob part 3 and movable knob part 4, fixed knob part 3 is fixed on electric energy meter cabinet body 1, movable knob part 4 is arranged on electric energy meter body 2, fixed knob part 3 and movable knob part 4 are rotationally connected, here fixed knob part 3 is fixed on electric energy meter cabinet body 1 and does not move, movable knob part 4 rotates around fixed knob part 3 longitudinally, electric energy meter body 2 on movable knob part 4 also adjusts longitudinal angle along with movable knob part 4.

[0024] The fixed rotary part is a cylinder and is internally hollow to form a cavity 5. A first tooth ring 6 is arranged near the side of the cavity 5 close to the movable rotary part. A rotation hole 9 is arranged at the center of the first tooth ring 6 for the rotation shaft 8 to pass through. One end of the rotation shaft 8 is connected with the movable rotary knob 4, and the other end extends into the cavity 5 and is connected with a second tooth ring 7. The second tooth ring 7 is engaged with the first tooth ring 6. Since the first tooth ring 6 is fixed and cannot rotate, the second tooth ring 7 is also fixed on the first tooth ring 6 and cannot rotate relative to the first tooth ring 6, so that the electric energy meter body 2 is fixed at a position. The side wall of the second tooth ring 7 away from the first tooth ring 6 is connected with the side wall of the cavity 5 away from the first tooth ring 6 through a spring 12. The spring 12 always presses the second tooth ring 7 towards the first tooth ring 6, so that the two tooth rings are kept in close engagement to prevent accidental rotation. When the angle of the electric energy meter body 2 needs to be adjusted, the movable rotary knob 4 is manually pushed towards the fixed rotary knob 3. At this time, the second tooth ring 7 is separated from the first tooth ring 6, and the movable rotary knob 4 can rotate freely around the fixed rotary knob 3. The electric energy meter body 2 is adjusted in angle. After the spring 12 pushes the second tooth ring 7 back to its original position and re-engages with the first tooth ring 6, the electric energy meter is stably locked after the angle adjustment.

[0025] As an embodiment of the present application, a gap is left between the fixed rotary knob 3 and the movable rotary knob 4, which is greater than the tooth height of the first tooth ring 6. When the movable rotary knob 4 is pushed, the second tooth ring 7 can completely separate from the engagement range of the first tooth ring 6, so as to avoid the interference between the tooth rings affecting the free rotation of the electric energy meter body 2.

[0026] As an embodiment of the present application, a first installation groove 10 is arranged on the side wall of the second tooth ring 7 away from the first tooth ring 6. A second installation groove 11 is arranged on the side wall of the cavity 5 away from the first tooth ring 6. The spring 12 is arranged in the first installation groove 10 and the second installation groove 11. The first installation groove 10 and the second installation groove 11 are both circular grooves. The spring 12 is arranged in the two grooves to ensure that the spring 12 remains stable during work and does not deviate or fall off, so as to effectively maintain the pressure of the second tooth ring 7 on the first tooth ring 6.

[0027] As an embodiment of the present application, the distance between the first installation groove 10 and the second installation groove 11 is greater than the gap between the fixed rotary knob 3 and the movable rotary knob 4, so as to ensure that the spring 12 has enough deformation space during compression, thereby avoiding the problems of loose engagement or difficult adjustment caused by insufficient compression stroke.

[0028] As an embodiment of the present application, the electric meter cabinet body 1 is provided with two adjusting assemblies, which are symmetrically arranged on the two sides of the electric meter body 2 along the vertical direction of the electric meter body 2, so as to improve the stability and carrying capacity of adjustment; the fixed knob part 3 of each adjusting assembly is welded and fixed with the electric meter cabinet body 1, and the movable knob part 4 is fixedly connected with the electric meter body 2 through bolts, so as to facilitate disassembly, assembly and maintenance.

[0029] As an embodiment of the present application, the connecting end of the movable knob part 4 and the fixed knob part 3 is cylindrical, and the rotating shaft 8 is installed at the center of the movable knob part 4, so as to ensure the concentricity and stability of the movable knob part 4 and the fixed knob part 3 during rotation.

[0030] As an embodiment of the present application, at least one of the tooth shapes of the first tooth ring 6 and the second tooth ring 7 is provided with a guide slope, so as to facilitate quick alignment and combination when the two are engaged; in this embodiment, the tooth shape of the first tooth ring 6 is provided as a trapezoidal body, and the tooth shape of the second tooth ring 7 is provided as a rectangular body, so as to guide the second tooth ring 7 to smoothly enter the engagement position of the first tooth ring 6 during the reset process of the spring 12, and avoid the situation that the second tooth ring 7 is stuck or not engaged in place due to tooth position deviation.

[0031] As an embodiment of the present application, the number of teeth of the first tooth ring 6 is at least two, and the two teeth are symmetrically arranged; in this technical solution, the function of the first tooth ring 6 is to fix the second tooth ring 7 to prevent the second tooth ring 7 from rotating, so as to realize the fixation of the electric meter body 2; in this embodiment, the number of teeth of the first tooth ring 6 is the same as the number of teeth of the second tooth ring 7, which is beneficial to the alignment and combination when the two are engaged; in the case that the number of teeth is equal, the engagement process can be ensured to be more stable, and the overall durability and adjustment accuracy of the structure are enhanced.

[0032] The working principle of the utility model is as follows: the working principle of the present solution is based on the cooperation of the tooth engagement mechanism of the adjusting assembly and the spring 12, so as to realize the longitudinal angle adjustment of the electric meter body 2. When a user needs to adjust the viewing angle of the electric meter body 2, the movable knob part 4 is rotated or the electric meter body 2 is manually pushed, the action is transmitted to the connecting rod, the connecting rod drives the second tooth ring 7 to rotate in the cavity 5, since the second tooth ring 7 is engaged with the first tooth ring 6, the rotation of the second tooth ring 7 will force the first tooth ring 6 to relatively displace, but since the first tooth ring 6 is fixed to the fixed knob part 3, the actual result is that the second tooth ring 7 and the connecting rod drive the movable knob part 4 and the electric meter body 2 to rotate, so as to change the pitch angle; during the adjustment process, the spring 12 is compressed, the second tooth ring 7 temporarily separates from the first tooth ring 6 to facilitate smooth rotation; once the external force is released, the elastic restoring force of the spring 12 pushes the second tooth ring 7 back to the original position, so that the second tooth ring 7 is re-engaged with the first tooth ring 6, realizing the self-locking function and ensuring the angle fixation. The whole adjustment process is simple and efficient, the user can complete it without tools, and the structure is compact, which is suitable for narrow space.

[0033] The above merely illustrates the embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, which are made according to the content of the present application specification and drawings, are also included in the patent protection scope of the present application.
