Description

Technical Field

[0001] The utility model relates to the technical field of electric meter boxes, in particular to an installation structure of an electric meter box. Background Art

[0002] An electric meter box refers to a box used for installing and protecting electric energy metering instruments and their related electrical equipment. It is usually made of metal materials and has certain protection performance to protect the electric meter and other equipment from the influence and damage of the external environment.

[0003] In the prior art, according to different application occasions, many electric meter boxes are installed on the open-air wall surface outdoors. However, the wall surface is affected by different temperatures in different seasons and time periods, resulting in thermal expansion and contraction, causing slight deformation of the wall surface, generating mechanical deformation, and further having a certain impact on the fixing and connecting components of the electric meter box, easily leading to loosening of screws, fracture of joints, etc. Therefore, we propose a new installation structure of an electric meter box. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems existing in the prior art that the wall surface is affected by different temperatures in different seasons and time periods, resulting in thermal expansion and contraction, causing slight deformation of the wall surface, generating mechanical deformation, and further having a certain impact on the fixing and connecting components of the electric meter box, easily leading to loosening of screws, fracture of joints, etc., and to propose an installation structure of an electric meter box.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: an installation structure of an electric meter box, including an electric meter box body and a wall surface. Fixed blocks are arranged at positions close to the four corners on the rear surface of the electric meter box body. A hanging rod is sleeved on the rear end face of the fixed block. A movable block is arranged on the outer surface of the hanging rod. A through groove is arranged at a position close to the bottom on the outer surface of the movable block, and the through groove corresponds to the hanging rod.

[0006] Further, a first bolt is arranged on the front surface of the movable block, and the outer surface of the first bolt slidably penetrates through the front surface of the movable block and extends to the other side.

[0007] Further, the first bolt is threadedly connected to the front surface of the wall surface, and a second nut is threadedly connected to the outer surface of the first bolt.

[0008] Further, a threaded rod is fixedly connected to the front end face of the fixed block. The outer surface of the threaded rod slidably penetrates through the rear surface of the electric meter box body and extends to the inside, and a first nut is threadedly connected to the outer surface of the threaded rod.

[0009] Further, a connecting block is fixedly connected to the rear end face of the hanging rod, and an installation cover is sleeved on the outer surface of the connecting block.

[0010] Furthermore, a damper is fixedly installed on the rear end face of the connecting block. A spring is sleeved outside the damper. One end of the spring is fixedly connected to the rear end face of the connecting block, and the other end of the spring is fixedly connected to the inner wall of the mounting cover.

[0011] Furthermore, a connecting plate is provided on the top of the electric meter box body. A second bolt is provided at a position near the front side of the top of the connecting plate. The outer surface of the second bolt slidably penetrates through the top of the connecting plate and is threadedly connected to the electric meter box body. A rain shield is fixedly connected to a position near the rear side of the top of the connecting plate.

[0012] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.

[0013] 1. In the present utility model, when the electric wall undergoes slight deformation due to thermal expansion and contraction under the influence of temperature, it drives the position of the first bolt to change synchronously. The movable blocks are mutually involved and rotate on the first bolt. Since the hanging rod has sufficient free movement space in the through groove, when the movable blocks rotate and displace, the hanging rod can move freely in the through groove. Moreover, the thickness of the movable block is slightly smaller than the length of the hanging rod, so that the movable block also has sufficient freedom on the hanging rod, making the position of the hanging rod and the electric meter box body always relatively fixed, and not strongly pulling the electric meter box body. This greatly reduces the influence of wall thermal expansion and contraction on the electric meter box body and reduces the probability of screw loosening and connection breakage.

[0014] 2. In the present utility model, by installing the rain shield on the connecting plate on the electric meter box body and making the rain shield fit the wall surface, it can play a role in preventing rain, avoiding the connecting components in the device from being eroded by water, and improving the service life.

[0021] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0022] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0023] Embodiment 1, as Figures 1-4 shown, the present invention provides an installation structure for an electric meter box, including an electric meter box body 1 and a wall surface 2. Fixed blocks 3 are provided at positions near the four corners on the rear surface of the electric meter box body 1. A hanging rod 33 is sleeved on the rear end face of the fixed block 3. A movable block 4 is provided on the outer surface of the hanging rod 33. A through groove 41 is provided at a position near the bottom of the outer surface of the movable block 4. The through groove 41 corresponds to the hanging rod 33. A first bolt 42 is provided on the front surface of the movable block 4. The outer surface of the first bolt 42 slidably penetrates the front surface of the movable block 4 and extends to the other side. The first bolt 42 is threadedly connected to the front surface of the wall surface 2. A second nut 43 is threadedly connected to the outer surface of the first bolt 42. A threaded rod 31 is fixedly connected to the front end face of the fixed block 3. The outer surface of the threaded rod 31 slidably penetrates the rear surface of the electric meter box body 1 and extends into the interior. A first nut 32 is threadedly connected to the outer surface of the threaded rod 31.

[0024] The effect achieved by the entire Embodiment 1 is that when installing the electricity meter box body 1, first, a hole is drilled at a specified position on the wall surface 2, then the movable block 4 is sleeved on the first bolt 42, and then the second nut 43 is also screwed onto the first bolt 42. Next, the first bolt 42 is installed into the hole in the wall surface 2 until the rear end face of the installation cover 37 fits against the wall surface 2. Then, the second nut 43 is screwed to fit tightly against the wall surface 2, thereby fixing the first bolt 42 on the wall surface 2 and making it not easy to shake. After that, the through holes near the four corners on the rear surface of the electricity meter box body 1 are aligned with the threaded rods 31, and the electricity meter box body 1 is sleeved on the threaded rods 31, so that the threaded rods 31 are embedded inside the electricity meter box body 1. Subsequently, the first nut 32 is screwed onto the threaded rods 31 from inside the electricity meter box body 1 to fix the electricity meter box body 1, thus completing the overall installation work of the electricity meter box body 1. When the wall surface 2 undergoes slight deformation due to thermal expansion and contraction under the influence of temperature, the positions of the multiple first bolts 42 will change. When the positions of the first bolts 42 change, the movable block 4 will rotate slightly on the first bolt 42 and involve other movable blocks 4 in rotating on the first bolt 42. Since the hanging rod 33 has sufficient free movement space in the through groove 41, when the movable block 4 undergoes rotational displacement, the hanging rod 33 can move freely in the through groove 41. Moreover, the thickness of the movable block 4 is slightly smaller than the length of the hanging rod 33, so that the movable block 4 also has sufficient freedom on the hanging rod 33, keeping the positions of the hanging rod 33 and the electricity meter box body 1 relatively fixed all the time and not strongly pulling the electricity meter box body 1, greatly reducing the influence of the thermal expansion and contraction of the wall surface 2 on the electricity meter box body 1.

[0025] Embodiment 2, as Figures 1-5 shown, a connecting block 34 is fixedly connected to the rear end face of the hanging rod 33. An installation cover 37 is sleeved on the outer surface of the connecting block 34. A damper 35 is fixedly installed on the rear end face of the connecting block 34. A spring 36 is sleeved outside the damper 35. One end of the spring 36 is fixedly connected to the rear end face of the connecting block 34, and the other end of the spring 36 is fixedly connected to the inner wall of the installation cover 37. A connecting plate 5 is provided on the top of the electricity meter box body 1. A second bolt 52 is provided at a position near the front side on the top of the connecting plate 5. The outer surface of the second bolt 52 slidably penetrates through the top of the connecting plate 5 and is threadedly connected to the electricity meter box body 1. A rain shield 51 is fixedly connected to a position near the rear side on the top of the connecting plate 5.

[0026] The effect achieved by the entire embodiment 2 is that, by making the mounting cover 37 and the wall 2 contact each other, the meter box body 1 can be supported as a whole, and the problem that the freedom between the hanging rod 33 and the through groove 41 causes the meter box body 1 to shake back and forth is compensated. When a slight bulge or warping occurs on the surface of the wall 2, the damper 35 and the spring 36 cooperate with each other to generate elastic force or contraction force, and the support amount can be adaptively adjusted according to the bulge amount of the meter box body 1 to improve stability. After the installation of the meter box body 1 is completed, the mounting hole on the connecting plate 5 is aligned with the mounting hole on the top of the meter box body 1, and then it is installed by the second bolt 52, thereby completing the installation of the rain shield 51, and the rain shield 51 and the wall 2 are in a fit state, which can play a rainproof role, avoid the connecting parts in the device from being eroded by water, and improve the service life.

[0027] Working principle: When the electric wall 2 is affected by temperature and expands and contracts slightly, the position between the multiple first bolts 42 will change. When the position of the first bolt 42 changes, the movable block 4 will rotate slightly on the first bolt 42, and involve other movable blocks 4 to rotate on the first bolt 42. Since the hanging rod 33 has enough free space in the through groove 41, when the movable block 4 rotates and displaces, the hanging rod 33 can move freely in the through groove 41. In addition, the thickness of the movable block 4 is slightly smaller than the length of the hanging rod 33, so that the movable block 4 also has enough freedom on the hanging rod 33, so that the position of the hanging rod 33 and the meter box body 1 is always relatively fixed, and will not affect the meter. The box body 1 is strongly pulled, which greatly reduces the influence of thermal expansion and contraction of the wall 2 on the meter box body 1. By making the mounting cover 37 and the wall 2 contact each other, the meter box body 1 can be supported as a whole, and the freedom between the hanging rod 33 and the through groove 41 will make up for the problem that the meter box body 1 shakes back and forth. When a slight bulge or warp occurs on the surface of the wall 2, the damper 35 and the spring 36 cooperate to generate elastic force or contraction force, and the support amount can be adaptively adjusted according to the bulge amount of the meter box body 1 to improve stability. The rain shield 51 and the wall 2 are in a fitted state, which can play a rainproof role, avoid water erosion of the connecting parts in the device, and improve the service life.

[0028] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
