DETAILED DESCRIPTION

[0027] The utility model will be further described below with specific examples in combination with the drawings, referring to Figures 1-4 :

[0028] Example 1

[0029] The embodiment provides a meter box with an anti-vibration frame structure, comprising a box frame 1 formed by a plurality of orthogonal shaft rods 2, wherein three reinforcing members 3 are arranged at the corner of the box frame 1, and each reinforcing member 3 comprises:

[0030] a fixing seat 30 fixedly connected to the shaft rod 2 at the corner and spaced apart from the adjacent shaft rod 2 to form a clamping groove 4;

[0031] a support plate 31 fixed to the outer side of the fixing seat 30 and abutting against the surface of the adjacent shaft rod 2;

[0032] an interlocking plate 32 fixed to the support plate 31 and extending into the clamping groove 4 of the adjacent reinforcing member 3;

[0033] wherein the fixing seat 30 of each reinforcing member 3 is located on three different shaft rods 2 at the corner, and each interlocking plate 32 is fixed with the corresponding fixing seat 30 and shaft rod 2 by a fastener 5 to form an interlocking structure.

[0034] The box frame 1 provides a mounting carrier for internal electrical elements, and bears and disperses external forces to ensure the stability of the overall structure of the box.

[0035] The corner is the three-dimensional corner position of the box frame 1, formed by the intersection of three orthogonal shaft rods 2, used to connect shaft rods 2 in different directions and transfer and converge external forces.

[0036] The reinforcing member 3 is used to improve the structural strength and anti-vibration ability of the corner, and avoid deformation of the corner under external force. The reinforcing member 3 comprises a fixed seat 30, a support plate 31 and an interlocking plate 32, and the overall structure is adapted to the space of the corner. The fixed seat 30 of each reinforcing member is fixedly connected with one of the three shafts 2 of the corner, and the three shafts 2 together cover the corner area. The fixed seat 30 is fixedly connected with the shaft 2, the support plate 31 is fixed with the fixed seat 30, and the interlocking plate 32 is fixed with the support plate 31. The interlocking plate 32 extends into the clamping groove 4 of the adjacent reinforcing member 3, and is fixed with the corresponding fixed seat 30 and shaft 2 through the fastener 5, thereby forming an interlocking system.

[0037] The fixed seat 30 is used to stably fix the reinforcing member 3 on the shaft 2, and forms a clamping groove 4 with the adjacent shaft 2 to provide installation space for the interlocking plate 32. The fixed seat 30 is in close contact with the outer surface of the shaft 2, and the shape is adapted to the shape of the shaft 2 to ensure close contact. The fixed seat 30 is fixedly connected with one of the three shafts 2 of the corner, and is spaced apart from the other two adjacent shafts 2 to form a clamping groove 4. The fixed seat 30 is fixedly connected with the shaft 2 by welding or bolts, and is fixed with the support plate 31 by welding or bolts, thereby providing a mounting base for the support plate 31 and realizing cooperation with the interlocking plate 32 through the clamping groove 4.

[0038] The support plate 31 is used to enhance the connection stability of the fixed seat 30 and the shaft 2, and to disperse and transmit external force to the adjacent shaft 2, thereby avoiding deformation of the single shaft 2 due to force concentration. The support plate 31 is a plate structure with certain structural strength, which can be in close contact with the surfaces of the fixed seat 30 and the shaft 2. The support plate 31 is fixed on the outer side of the fixed seat 30, and one end is integrally formed with the fixed seat 30, and the other end extends to the adjacent shaft 2 and abuts against the surface of the shaft 2 to form a lateral support for the shaft 2. The support plate 31 transmits stress through abutment with the surface of the shaft 2, and provides a mounting base for the interlocking plate 32, so that the interlocking plate 32 can be stably connected to the shaft 2, thereby forming an overall interlocking system.

[0039] The interlocking plate 32 is used to connect the adjacent reinforcing members 3 into a whole, and forms a structure that restricts each other to enhance the overall rigidity of the corner. The interlocking plate 32 is a plate structure with certain strength, which can adapt to the space size of the clamping groove 4. The interlocking plate 32 is fixed on the support plate 31, one end is integrally formed with the support plate 31, and the other end extends outward and is inserted into the clamping groove 4 of the adjacent reinforcing member 3, and cooperates with the fixed seat 30 and the shaft 2 in the clamping groove 4. The part of the interlocking plate 32 extending into the clamping groove 4 is fixed with the corresponding fixed seat 30 and shaft 2 through the fastener 5, so that the multiple reinforcing members 3 form a whole through the connection of the interlocking plate 32, and avoid loosening or displacement of the single member under stress.

[0040] The fastener 5 is used to fasten the interlocking plate 32, the corresponding fixing seat 30 and the shaft 2 into an integrated whole, to ensure that the interlocking structure is not loose, and to transfer and disperse external force; the structure is a standard fastening structure, including a screw rod and a nut, which are positioned through corresponding holes of the interlocking plate 32, the fixing seat 30 and the shaft 2, to ensure that the three components are connected at the same time, and by tightening the screw rod and the nut, the interlocking plate 32, the fixing seat 30 and the shaft 2 are tightly attached to form a rigid connection, avoiding relative displacement between the components.

[0041] In the above design, the box frame 1 of the electric meter box is composed of a plurality of orthogonal shafts 2, and the corner part is a stress concentration area. By arranging three reinforcing members 3 at the corner part, the fixing seat 30 of each member is fixed to three different shafts 2 at the corner part, and the supporting plate 31 is fixed outside the fixing seat 30 and abuts against the adjacent shaft 2, to provide lateral support for the shaft 2; at the same time, the interlocking plate 32 of each member extends into the clamping groove 4 of the adjacent member, and the interlocking plate 32, the corresponding fixing seat 30 and the shaft 2 are fastened into an integrated whole by the fastener 5, so that the three reinforcing members 3 form a cyclically interlocked overall structure. When the box is subjected to external force in multiple directions, the interlocking structure disperses the external force to the three shafts 2 at the corner part and the reinforcing members 3, and through the cooperative force resistance of the components, the corner part is prevented from loosening or deforming, thereby achieving the reinforcement of the frame against earthquakes.

[0042] The fixing seat 30 is an "L" shaped structure that is attached to the outer surface of the shaft 2, and is flush with the outer surface of the shaft 2 after being fixed. The purpose of the above design is to ensure that the fixing seat 30 is tightly connected with the shaft 2 and does not form an additional protrusion, to improve the compactness and force balance of the structure. The fixing seat 30 adopts an "L" shaped structure that is attached to the outer surface of the shaft 2, which can increase the contact area with the shaft 2, making the connection more stable and preventing the shaft 2 from deforming due to excessive local stress; after being fixed, it is flush with the outer surface of the shaft 2, which can eliminate the height difference between the two, neither occupying additional space, preventing external force from concentrating due to protruding structures, nor providing a flat foundation for the installation of the supporting plate 31 and the interlocking plate 32, to ensure that the components are tightly attached and form a cooperatively stressed overall structure.

[0043] The support plate 31 comprises two support portions 310 and a connecting portion 311. The two support portions 310 are symmetrically arranged between adjacent shafts 2. The connecting portion 311 connects the two support portions 310 and abuts against the shaft 2. The fastener 5 connects the connecting portion 311, the corresponding interlocking plate 32 and the corresponding shaft 2 together. The purpose of the above design is to strengthen the support of the shaft 2 and the stability of the connection between components through the structural division of the support plate 31, and to form a multi-directional force transmission path. The support portion 310 is configured as a plate-shaped structure that fits the gap between adjacent shafts 2, and is symmetrically arranged between adjacent shafts 2. It can form lateral support for the shaft 2 from both sides, avoiding the shaft 2 from deviating to one side when subjected to external force. The connecting portion 311 is configured as a plate-shaped structure that can simultaneously connect the two support portions 310. Its side is integrally formed with the support portion 310, and the other side abuts against the outer surface of the shaft 2. It not only realizes the coordinated linkage of the two support portions 310, but also directly transmits the force of the shaft 2 to the support portion 310. At the same time, the fastener 5 penetrates the connecting portion 311, the corresponding interlocking plate 32 and the corresponding shaft 2 and is fixed, so that the support plate 31, the interlocking plate 32 and the shaft 2 form a rigidly connected whole. The external force can be dispersed to the support portion 310 and the interlocking plate 32 through the connecting portion 311, further improving the anti-deformation ability of the frame corner and ensuring that each component is subjected to balanced force.

[0044] The interlocking plate 32 is in the shape of “ㄈ”, and is flush with the surface of the shaft 2 after being fixed. The purpose of the above design is to enable the interlocking plate 32 to stably fit the structure of the shaft 2 and the clamping groove 4 to achieve reliable interlocking, and to avoid forming an additional protrusion that affects the compactness of the overall structure. The interlocking plate 32 adopts the “ㄈ” shape, and the vertical edges on both sides can fit the shaft 2 on both sides, and the horizontal edge in the middle can fit the clamping groove 4 of the support plate 31 and the adjacent components. This shape design can increase the contact area of the interlocking plate 32 with the shaft 2 and the fixing seat 30, ensure the connection after being embedded in the clamping groove 4, and provide a stable installation basis for the fastener 5. After being fixed, it is flush with the surface of the shaft 2, which can eliminate the height difference between the interlocking plate 32 and the shaft 2, avoid the concentration of external force or interference with the installation of other components due to the protruding structure, and also reduce the risk of collision and prying of the interlocking plate 32 by the outside world, further ensuring the stability of the interlocking structure and making the overall stress of the corner more balanced.

[0045] The support part 310 is a plate-shaped structure with a beveled edge 3100. The purpose of the above design is to optimize the force transmission path through the beveled edge 3100 structure of the support part 310, and to enhance the support stability of the shaft rod 2. The support part 310 adopts a plate-shaped structure with a beveled edge 3100, which can adapt to the space angle between adjacent shaft rods 2, increase the adhesion to the surface of the shaft rod 2, and form a triangular support-like stress form. When the shaft rod 2 is subjected to external force and tends to deviate, the beveled edge 3100 can disperse the force in the inclined direction to the connecting part 311, avoiding stress concentration in a single contact point; this structure can also improve the structural strength of the support part 310 in limited space, reduce the deformation of the support part 310 itself under external force, further strengthen the lateral constraint of the support plate 31 to the shaft rod 2, and ensure that the frame corner always remains stable under stress.

[0046] The three reinforcing members 3 are connected by an auxiliary connecting plate 6, which includes a face plate 60 that is attached to the surface of each support plate 31. Each face plate 60 is connected to the corresponding support plate 31 by a fastener 5. The purpose of the above design is to further enhance the cooperative stress capacity of the three reinforcing members 3 and improve the overall structural stability of the frame corner. The auxiliary connecting plate 6 is a combined structure that includes three face plates 60, each of which is a plate-shaped form that fits the surface of the corresponding support plate 31 and tightly adheres to the outer surface of the corresponding support plate 31 to ensure sufficient contact area. In terms of connection, each face plate 60 is fixed to the corresponding support plate 31 by a fastener 5 such as a bolt, so that the three reinforcing members 3 form a complete connected whole through the auxiliary connecting plate 6, rather than independent stress units. This design can disperse the external force on a single reinforcing member 3 to the other two members, avoiding deformation of a single member due to excessive stress, while reducing the relative displacement between the reinforcing members 3, allowing the frame corner to form a more balanced stress system when facing multi-directional external forces, further enhancing the anti-seismic and anti-deformation ability of the meter box frame.

[0047] According to the content of the embodiment, in the process of assembling the electric meter box with the anti-seismic frame, the box frame 1 is first formed by a plurality of orthogonal shaft rods 2, then three reinforcing members 3 are installed at the corners of the frame, the "L"-shaped fixing seat 30 of each reinforcing member 3 is fixed to three different shaft rods 2 at the corners respectively, after being fixed, the fixing seat 30 is flush with the outer surface of the shaft rod 2 and forms a clamping groove 4 with the adjacent shaft rod 2, then the supporting plate 31 is fixed outside the fixing seat 30, the two supporting parts 310 with bevel edges 3100 of the supporting plate 31 are symmetrically arranged between the adjacent shaft rods 2, the connecting part 311 connects the two supporting parts 310 and abuts against the surface of the shaft rod 2, then the "ㄈ"-shaped interlocking plate 32 is fixed on the supporting plate 31, so that the interlocking plate 32 extends into the clamping groove 4 of the adjacent reinforcing member 3, after being fixed, the interlocking plate 32 is flush with the surface of the shaft rod 2, the interlocking plate 32, the connecting part 311 of the supporting plate 31 and the corresponding shaft rod 2 are fixed by the fastener 5, so that the three reinforcing members 3 form an interlocking structure, finally, the surface plates 60 of the auxiliary connecting plate 6 are respectively attached to the surface of the corresponding supporting plate 31, the surface plate 60 and the supporting plate 31 are connected by the fastener 5, so that the three reinforcing members 3 further cooperate. When the electric meter box is subjected to external force, the interlocking structure at the corner and the auxiliary connecting plate 6 jointly act on the external force and disperse the external force to the shaft rods 2, the reinforcing members 3 and the auxiliary connecting plate 6, the deformation is resisted by the cooperative stress of the components, and the anti-seismic protection of the box frame 1 is realized.

[0048] The above embodiment is only a preferred embodiment of the utility model, and does not limit the protection scope of the utility model, therefore: equivalent changes made according to the structure, shape and principle of the utility model should be covered in the protection scope of the utility model.
