DETAILED DESCRIPTION

[0025] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In the embodiment of the present invention, "and / or" is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0028] Reference example Figures 1 to 6 , an electric energy meter box with a buffering function, comprising a box body 1, a box door 2, and a hinge 3 fixed on one side of the box body 1 and the box door 2, the hinge 3 comprising a first connecting piece 4, a second connecting piece 5, and a spring piece 6, a first through hole 8 is arranged on both sides of the first connecting piece 4, a plurality of convex bumps 81 are evenly distributed on the inner wall of the first through hole 8 from top to bottom with a dot as the axis, a connecting rod 51 is arranged on both sides of the second connecting piece 5, and is pivotally arranged on the first through hole 8, the connecting rod 51 is provided with a concave cavity 52 corresponding to the convex bump 81, the convex bump 81 is arranged in the concave cavity 52, the spring piece 6 is fixed on the first connecting piece 4, and is located on the trajectory of the second connecting piece 5 rotating activity;

[0029] It is worth mentioning that the first connecting piece 4 is provided with an opening 41, the first connecting piece 4 is provided with a detachable cover plate 7, the first connecting piece 4 is provided with a recess 42, the opening 41 is provided for the pressing block to rotate therein, the detachable cover plate 7 facilitates the connection between the connecting rod 51 and the first through hole 8, and the recess 42 provides a space for accommodating the spring piece 6;

[0030] It is worth mentioning that the first through hole 8 is arranged on both sides of the opening 41 and the cover plate 7. Buckles 71 are arranged on both sides of the cover plate 7, and pass through the first connecting piece 4, and are buckled on the first connecting piece 4 to form a hole wrapped around the connecting rod 51. A spacing is left between the first through hole 8 and the connecting rod 51 for the convex bump 81 to enter the next concave cavity 52. ​​The buckle 71 facilitates the removal of the cover plate 7 from the first connecting piece 4 or installation on the first connecting piece 4. The spacing reduces the wear of the convex bump 81 during the movement of entering the concave cavity 52, thereby increasing the service life of the hinge 3. When the door 2 is opened or closed, the connecting rod 51 is rotated in the first through hole 8 to make the concave cavity 52 leave the convex bump 81. The convex bumps 81 arranged opposite to each other abut against the surface of the connecting rod 51, thereby increasing the friction when the door 2 is opened, and reducing the impact force when the door 2 rotates too much.

[0031] It is worth mentioning that the first connecting sheet 4 is provided with a second through hole 43 for the buckle 71 to pass through, and is arranged on both sides of the first through hole 8. When the buckle 71 enters the second through hole 43, the second through hole 43 allows the buckle 71 to store energy and allows the buckle 71 to pass through. After the buckle 71 passes through, the buckle 71 releases its elastic force, so that the buckle 71 is buckled on the end surface of the second through hole 43, so that the cover plate 7 is connected and fixed to the first connecting sheet 4;

[0032] It is worth mentioning that the spring sheet 6 is arranged in the yield groove 42, the spring sheet 6 is provided with a curved portion 61 and faces the second connecting piece 5, the spring sheet 6 is provided with a stop block 9, and the stop block 9 is provided with a contact surface 91. When the box door 2 is opened, it is subjected to an excessively large pushing force, so that the box door 2 quickly moves toward the curved portion 61. When the box door 2 abuts against the curved portion 61 and pushes the curved portion 61 to continue to move, the curved portion 61 stores energy and buffers the pushing force, thereby reducing the impact force when the box door 2 is opened. The spring sheet 6 cooperates with the friction between the convex hull 81 entering the concave cavity 52, thereby further reducing the impact force of the box door 2. When the box door 2 is subjected to a force exceeding the stored energy of the spring sheet 6, the curved portion 61 abuts against the contact surface 91, thereby preventing the box door 2 from violently colliding with the wall, and at the same time, providing protection for the spring sheet 6.

[0033] It is worth mentioning that a connecting column 92 is provided at the bottom of the limit block 9 and passes through the first connecting piece 4. The connecting column 92 is provided with a fastening screw 93, and the head of the fastening screw 93 is flush with the surface of the first connecting piece 4. The fastening screw 93 facilitates the removal or fixation of the limit block 9, the spring piece 6 and the first connecting piece 4. The head of the fastening screw 93 is flush with the surface of the first connecting piece 4 to prevent interference with the connection between the first connecting piece 4 and the cabinet;

[0034] It is worth mentioning that the second connecting piece 5 is provided with a pressure block 53 and is arranged at the opening 41. The connecting rod 51 is arranged on both sides of the pressure block 53. The rotational force of the door 2 is transmitted to the connecting rod 51 through the pressure block 53. The connecting rod 51 rotates around the first through hole 8 as the axis.

[0035] It is worth mentioning that mounting holes 9.1 are provided on both sides of the first connecting piece 4 and the second connecting piece 5, and countersunk holes 9.11 are provided in the mounting holes 9.1. The entrance of the countersunk holes 9.11 is on the same plane as the buckling position of the buckle 71. A fastener is placed in the mounting hole 9.1 so that the head of the fastener is set in the countersunk hole 9.11 and the head of the fastener is flush with the first connecting piece 4 and the second connecting piece 5.

[0036] The above design scheme can enable the product to achieve the advantages of buffering function and anti-collision.

[0037] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
