[0014] Optionally, a plurality of heat dissipation holes are provided on the limiting side plate.

[0015] In a second aspect, the present application provides an electric meter box, comprising an electric meter box body and the above-mentioned electric meter box mounting structure, wherein the mounting structure is used to fix the electric meter box body to a wall; The meter box body has two oppositely arranged limiting side walls.

[0027] It should be understood that although the terms "first", "second", "third", etc. may be used in the present application to describe various information, such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. In addition, the terms "vertical", "horizontal", "upper", "lower" and similar expressions used in the present application are positional relationships with reference to the accompanying drawings, and do not represent the expression of the only embodiment.

[0028] The embodiments of the present application are further described in detail below in conjunction with the accompanying drawings.

[0029] Reference Figure 2 The embodiment of the present application discloses an electric meter box 1, including an electric meter box body 2 and a mounting structure 3, wherein the mounting structure 3 is used to fix the electric meter box body 2 to a wall.

[0030] Reference Figure 2 , Figure 3 and Figure 4The mounting structure 3 includes a base 31, a support base 32, and a limiting side plate 33. The base 31 is used to be fixed on the wall. The base 31 includes a fixing plate 311 and a bottom plate 312. The fixing plate 311 and the bottom plate 312 are vertically arranged. The fixing plate 311 is located on the upper side of the bottom plate 312 and the two are fixedly connected. The fixing plate 311 and the bottom plate 312 are combined to form an L shape. The bottom plate 312 is used to support the support base 32 and the meter box body 2. In order to improve the bearing capacity of the bottom plate 312, the thickness of the bottom plate 312 gradually increases in the direction close to the fixing plate 311.

[0031] Reference Figure 5 and Figure 6 The meter box body 2 has two oppositely disposed limiting side walls 21. When the meter box body 2 is fixed to the wall, the limiting side walls 21 are vertically disposed, and the spacing between the two limiting side walls 21 gradually decreases in the direction away from the wall. The limiting side walls 21 are provided with a plurality of through holes 22 for heat dissipation. In order to facilitate the carrying of the meter box body 2, a handle 23 is fixed to each limiting side wall 21.

[0032] Reference Figure 6 and Figure 7 , the base 31 can be fixed by screws 313, that is, the fixing plate 311 is fixed to the wall by screws 313. The screws 313 on the fixing plate 311 can be arranged near the center of the fixing plate 311. Therefore, after the electric meter box body 2 is installed, the electric meter box body 2 shields the screws 313, reducing the possibility of the screws 313 getting damp and rusting. It should be understood that the base 31 can also be fixed by other conventional fixing methods such as rivets and bolts, and this embodiment does not limit this. The present application can use the electric meter box body 2 to shield rivets or bolts, etc., thereby avoiding the possibility of rivets or bolts getting damp and rusting.

[0033] Reference Figure 7 The support seat 32 is slidably connected to the base 31 along a first direction. When the base 31 is fixed to a wall, the first direction is a vertical direction. Specifically, a guide column 314 is fixed to the base 31, and two limit rods 321 are connected to the support seat 32. The guide column 314 is located between the two limit rods 321. The limit rod 321 and the guide column 314 are slidably fitted, and the guide column 314 and the limit rod 321 are parallel to the first direction. Therefore, under the sliding cooperation between the two limit rods 321 and the guide column 314, the support seat 32 can stably slide along the first direction.

[0034] Reference Figure 7A first elastic member 35 is connected between the bottom plate 312 and the support seat 32, and the first elastic member 35 is a compression spring. It should be understood that in order to prevent the compression spring from getting wet, a protective structure such as a telescopic sleeve or a bellows can also be set on the compression spring. After the meter box body 2 is placed on the support seat 32, the first elastic member 35 applies an elastic force along the first direction to the support seat 32 to support the meter box body 2. Since the first elastic member 35 has a shock-absorbing effect on the vertical direction of the meter box body 2, it can ensure the stability of the meter box body 2 under conditions of severe vibration such as near factories.

[0035] Reference Figure 4 and Figure 5 , two limiting side plates 33 are arranged relatively, and the limiting side plates 33 correspond to the limiting side walls 21 one by one. The limiting side plates 33 are closely attached to the limiting side walls 21, so that the limiting side plates 33 limit the meter box body 2, thereby fixing the meter box body 2. Since the limiting side plates 33 and the meter box body 2 are in surface contact, the contact area is large, which improves the stability of the meter box body 2. Each limiting side plate 33 is provided with a plurality of heat dissipation holes 331, and the positions and shapes of the heat dissipation holes 331 correspond to the through holes 22 on the meter box body 2.

[0036] Reference Figure 6 and Figure 7 The limiting side plate 33 is rotatably connected to a rotating shaft 332, and the rotating shaft 332 is parallel to the first direction. A second elastic member 36 is connected between the rotating shaft 332 and the guide column 314. The second elastic member 36 forces the two limiting side plates 33 to always have a tendency to move toward each other, and the limiting side plates 33 can be pulled to move by pulling the rotating shaft 332. When the meter box body 2 is fixed to the wall, the rotating shaft 332 is located between the meter box body 2 and the fixing plate 311.

[0037] Reference Figure 6 and Figure 7 The mounting structure 3 further includes a linkage assembly 34, and a third elastic member 37 is connected to the linkage assembly 34. After the operator holds the handle 23 and puts the meter box body 2 between the two limiting side plates 33, the linkage assembly 34 cooperates with the support seat 32 to push the third elastic member 37 toward the limiting side plate 33. When the base 31 is fixed to the wall, the third elastic member 37 is located on the side of the rotating shaft 332 close to the wall. Therefore, the limiting side plate 33 can be driven to rotate around the rotating shaft 332 by using the third elastic member 37 to push the limiting side plate 33.

[0038] Therefore, under the push of the third elastic member 37 and the pull of the second elastic member 36, the limiting side plate 33 can be fitted with the limiting side wall 21. Specifically, the second elastic member 36 and the third elastic member 37 are both telescopic rod structures, the telescopic rod of the second elastic member 36 has a tension spring built in, and the telescopic rod of the third elastic member 37 has a compression spring built in.

[0039] Reference Figure 6 and Figure 7 There are two second elastic members 36, which correspond to the limiting side plates 33. There are two third elastic members 37, which correspond to the limiting side plates 33. There are two linkage components 34, which correspond to the limiting side plates 33.

[0040] Reference Figure 7 and Figure 8 The linkage assembly 34 includes a first driving block 341 and a second driving block 342, wherein the first driving block 341 is fixedly connected to the support base 32. Specifically, the first driving block 341 is fixedly connected to the limit rod 321, and the second driving block 342 is slidably connected to the base 31 along a second direction, and the second direction is perpendicular to the first direction. Specifically, when the base 31 is fixed to a wall, the second direction is a horizontal direction.

[0041] Reference Figure 7 The guide column 314 is connected with a guide cross bar 315 corresponding to the linkage assembly 34 one by one, and the second driving block 342 can be slidably connected to the lower surface of the guide cross bar 315 through a T-shaped slider or a dovetail-shaped slider.

[0042] Reference Figure 7 and Figure 8 The first driving block 341 has a first inclined surface 3411, and the second driving block 342 has a second inclined surface 3421, and the first inclined surface 3411 and the second inclined surface 3421 are slidably fitted. The side of the second driving block 342 away from the first driving block 341 is fixedly connected to one end of the third elastic member 37, and the end of the third elastic member 37 away from the second driving block 342 is fixed with a spherical abutment block 371. Therefore, the spherical abutment block 371 pushes the limiting side plate 33, which can reduce the friction damage between the abutment block 371 and the limiting side plate 33. When the base 31 is fixed to the wall, the top ends of the first inclined surface 3411 and the second inclined surface 3421 extend toward the limiting side plate 33.

[0043] After the meter box body 2 is placed on the support seat 32, the meter box body 2 is lowered by gravity, thereby driving the support seat 32 to lower, and the support seat 32 drives the first driving block 341 to lower through the limiting rod 321, and the first driving block 341 pushes the second inclined surface 3421 through the first inclined surface 3411, thereby driving the second driving block 342 to move toward the corresponding limiting side plate 33. The second driving block 342 drives the third elastic member 37 to move toward the limiting side plate 33, so that the limiting side plate 33 can be pushed to rotate through the abutment block 371, and under the cooperation and pulling of the second elastic member 36, the inclination angle of the limiting side plate 33 is fitted to the limiting side wall 21 of the meter box body 2.

[0044] Reference Figure 7 and Fig. 9 In order to install the meter box body 2 in the center of the mounting structure 3 and improve the stability of lifting and lowering the meter box body 2 during construction, two slide rails 24 are fixed to the back of the meter box body 2. After the meter box body 2 is installed in the mounting structure 3, the guide column 314 is located between the two slide rails 24.

[0045] Reference Figure 6 and Figure 7 The mounting structure 3 further includes a sealing cover 38, which is located on the top of the fixing plate 311. The sealing cover 38 and the base 31 are detachably plugged together, and the sealing cover 38 is used to cover the top of the meter box body 2. Specifically, a plug rod 39 is fixed to the bottom of the sealing cover 38, and a slot 3141 is provided on the top of the guide column 314, and the plug rod 39 is inserted into the slot 3141. The top of the sealing cover 38 has a guiding slope 381, so as to prevent foreign matter such as water from accumulating on the top of the sealing cover 38.

[0046] Reference Figure 4 After the meter box body 2 is installed in the installation structure 3, an escape space 382 is provided between the lower surface of the sealing cover 38 and the upper surface of the meter box body 2.

[0047] The implementation principle of the electric meter box 1 disclosed in the embodiment of the present application during installation is as follows: first, the fixing plate 311 is fixed to the wall by fixing parts such as screws 313, and the screws 313 are arranged near the center of the fixing plate 311. At this time, under the elastic force of the first elastic member 35, the support seat 32 is located at a higher position, so that the driving force of the third elastic member 37 on the limiting side plate 33 is small, and the construction personnel can easily rotate the limiting side plate 33 to enlarge the opening of the two limiting side plates 33 away from the fixing plate 311 (such as Figure 6 As shown), it is convenient for the operator to hold the handle 23 and put the meter box body 2 between the two limit side plates 33. After releasing the handle, the meter box body 2 can be placed on the support seat 32.

[0048] After the meter box body 2 is placed on the support seat 32, the meter box body 2 is lowered by gravity, thereby driving the support seat 32 to lower, and the support seat 32 drives the first driving block 341 to lower through the limiting rod 321, and the first driving block 341 pushes the second inclined surface 3421 through the first inclined surface 3411, thereby driving the second driving block 342 to move toward the corresponding limiting side plate 33. The second driving block 342 drives the third elastic member 37 to move toward the limiting side plate 33, so that the limiting side plate 33 can be pushed to rotate through the abutment block 371, and under the cooperation and pulling of the second elastic member 36, the inclination angle of the limiting side plate 33 is fitted to the limiting side wall 21 of the meter box body 2.

[0049] Since the meter box body 2 shields the screws 313 on the fixing plate 311, the possibility of the screws 313 getting damp and rusting is reduced. The first elastic member 35, the second elastic member 36 and the third elastic member 37 cooperate with each other to cushion the shock in multiple directions of the meter box body 2, thereby improving the shock resistance of the meter box body 2. In addition, the contact area between the limiting side plate 33 and the meter box body 2 is large, so that the meter box body 2 is relatively stable.

[0050] The implementation principle of the meter box 1 disclosed in the embodiment of the present application during disassembly is as follows: the operator holds the handle 23 to lift the meter box body upwards. Since there is an avoidance space 382 between the sealing cover 38 and the meter box body 2, it is not necessary to remove the sealing cover 38 when removing the meter box body 2 from the mounting structure 2. After the meter box body is lifted, the support seat 32 pops up, thereby releasing the restriction of the linkage assembly on the third elastic member 37. At this time, the limiting side plate 33 can rotate to a larger extent and the resistance of the limiting side plate 33 to the third elastic member 37 is smaller, so the meter box body 2 can be easily pulled out from between the two limiting side plates 33.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
