Description

Technical Field

[0001] The invention belongs to the technical field of meter boxes, and in particular relates to a multi-meter-position electric energy meter box. Background Art

[0002] An energy meter is a device used to measure electrical energy, usually used in homes, businesses and industrial sites. It can measure the consumption of electrical energy and record relevant electrical energy data, such as voltage, current, power factor, etc. Some energy meter boxes also support remote monitoring functions. When abnormal conditions are detected, such as excessive voltage or excessive current, an alarm signal can be issued to remind users to take measures.

[0003] Most of the existing electric energy meter boxes are multi-meter designs, generally including a box body with multiple electric energy meters installed inside the box body, and a transparent display window is also provided on the outer side of the box body, through which users can easily read the electric energy meters; however, in actual use, the electric energy meter box is often set in an outdoor environment. After long-term use, a lot of dust and oil stains may accumulate on the display window, and users must clean it before reading, which is inconvenient. Therefore, it is necessary to specifically design a multi-meter electric energy meter box that can be easily read after long-term use outdoors. Summary of the invention

[0004] The existing multi-meter electric energy meter box, after being used outdoors for a long time, the display window arranged on the box body will accumulate dust and oil stains, making it inconvenient for users to read the electric energy meter in the box body, which is quite inconvenient. For this reason, the following invention is now proposed: A multi-meter-position electric energy meter box comprises a box body and a box surface arranged on the front side of the box body, wherein the box surface is provided with a plurality of inwardly recessed chambers, and an inner display window is fixedly provided on the innermost side of the chamber. The invention is characterized in that: a plurality of dust covers are also provided on the box surface, and the dust covers cover the outer side of the chamber opening to separate the inner display window from the outside world. The box surface is also provided with a snap-fit ​​seat located on the upper and lower sides of the dust cover, and the snap-fit ​​seat is provided with a snap-fit ​​hole. The side of the dust cover is rotatably connected with a snap-fit ​​plate, and the snap-fit ​​plate is provided with a snap-fit ​​head. After the snap-fit ​​plate is rotated, the snap-fit ​​head is inserted into the snap-fit ​​hole to prevent the dust cover from detaching from the box surface.

[0005] After removing the dust cover, the inner display window can be observed and read. After the dust cover is installed and fixed by the snap plate, the dust can be isolated from the chamber to avoid the inner display window being difficult to observe and read normally due to dust accumulation during long-term use.

[0006] Furthermore, the dust cover is provided with a plurality of fixing holes, in which a fixing column is fixedly inserted, and the fixing column is connected with a baffle. When the snap-fit ​​head is inserted into the snap-fit ​​hole, the baffle blocks the snap-fit ​​plate to prevent it from rotating, thereby preventing the snap-fit ​​plate from rotating when subjected to pressure, thereby improving the stability and reliability of the snap-fit ​​plate fixing the dust cover.

[0007] Furthermore, the locking plate is also provided with a push plate, and an arc push head is provided on the push plate. After the locking head is separated from the locking hole, the push plate contacts the dust cover part, and the arc push head is always separated from the dust cover.

[0008] Furthermore, a connecting seat is provided on the dust cover, a notch is provided on the connecting seat, a connecting plate is provided on the snap plate, and the connecting plate is movably connected in the notch.

[0009] Furthermore, an inner dust shielding plate extending outward is provided at the opening of the chamber, and an outer dust shielding plate extending inward and covering the outer side of the inner dust shielding plate is provided on the dust cover. The inner dust shielding plate and the outer dust shielding plate form a double-layer dust shielding structure, which greatly reduces the possibility of dust entering the chamber.

[0010] Furthermore, an outer display window is fixedly provided on the inner side of the dust cover, and the user can directly observe the reading on the inner display window through the outer display window. When a lot of dust accumulates on the outer display window, the outer display window can be replaced together with the dust cover, which is more convenient.

[0011] Furthermore, the bottom of the chamber is provided with an inclined surface extending obliquely upward, and the lower structure can reduce the accumulation of dust entering the chamber.

[0012] The present invention proposes a multi-meter-position electric energy meter box, comprising a box surface and a plurality of chambers arranged on the box surface, wherein inner display windows and dust covers are respectively arranged inside and outside the chambers, wherein the dust covers separate the chambers from the outside, thereby better preventing dust from accumulating on the inner display windows and affecting normal observation; after an outer display window is arranged on the dust cover, an operator can directly observe the inner display window through the outer display window; during long-term use, a lot of dust and oil stains will also accumulate on the outer display window, and it is difficult to clean them directly; at this time, the outer display window can be directly replaced by replacing the dust cover, which is more convenient.

[0015] The technical solution of the present invention will be clearly and completely described below in conjunction with embodiments.

[0016] Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative work should fall within the scope of protection of this application.

[0017] In the present application, the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inner", "outer", "middle", "vertical", "horizontal", "lateral", "longitudinal" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings. These terms are mainly used to better describe the present invention and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation.

[0018] In addition to being used to indicate a position or location relationship, some of the above terms may also be used to indicate other meanings. For example, the term "on" may also be used to indicate a certain dependency or connection relationship in some cases. For those skilled in the art, the specific meanings of these terms in the present invention can be understood according to specific circumstances.

[0019] like Figure 1-Figure 3 As shown, it is a preferred embodiment of the present invention, a multi-meter electric energy meter box, including a box body 1, a box surface 2 is provided on the front side of the box body 1, and a plurality of inwardly recessed chambers 31 are provided on the box surface 2. In this embodiment, the number of the chambers 31 is 9, which are arranged in a 3×3 arrangement, and an inner display window 3 is fixedly provided on the innermost side of the chamber 31. A dust cover 4 matching the chamber 31 one by one is also provided on the box surface 2, wherein the dust cover 4 blocks the outer side of the opening of the chamber 31 and separates the inner display window 3 from the outside. Furthermore, a snap-fit ​​seat 21 is respectively provided on the upper and lower sides of the opening of each chamber 31, and a penetrating snap-fit ​​hole 22 is provided on the snap-fit ​​seat 21, and a snap-fit ​​plate 5 is rotatably connected to the upper and lower sides of the dust cover 4.

[0020] After the dust cover 4 is installed on the outside of the opening of the chamber 31, dust can be prevented from entering the chamber 31, which would cause the inner display window 3 to be unable to observe the reading during long-term use. When it is necessary to read the reading of the electric energy meter installed in the box body 1, the dust cover 4 can be removed. At the same time, in order to prevent the dust cover 4 from detaching from the box surface 2, after the dust cover 4 is installed, the locking plate 5 is rotated until the locking head 51 is locked and inserted into the locking hole 22. The dust cover 4 is then locked by the locking head 51 and the locking hole 22 and cannot be directly removed from the box surface 2. To remove the dust cover 4, you only need to rotate the locking plate 5 in the opposite direction.

[0021] Although the engagement of the engagement head 51 and the engagement hole 22 can prevent the dust cover 4 from directly separating from the box surface 2, the engagement plate 5 is still prone to rotate when pressed by an external force. Figure 2 and Figure 4 As shown, the dust cover 4 is also provided with a plurality of fixing holes 44, and a fixing column 71 is fixedly inserted into the fixing hole 44. A square baffle 7 is fixedly connected to the outer side of the fixing column 71. When the locking head 51 is inserted into the locking hole 22, the baffle 7 blocks the locking plate 5 from below or above to prevent it from rotating, thereby avoiding the problem that the locking plate 5 is easily rotated by external force.

[0022] Furthermore, a push plate 52 is also provided on the locking plate 5, and an arc push head 53 is provided on the end of the push plate 52. The operator can push the push plate 52 by pressing the arc push head 53, thereby controlling the locking plate 5 to rotate. During the rotation of the locking plate 5, no matter whether the locking head 51 is engaged with the locking hole 22, the arc push head 53 is always separated from the dust cover 4; specifically, a connecting seat 43 is provided on the dust cover 4, and a notch is provided on the connecting seat 43, and a connecting plate 54 is provided on the locking plate 5, and the connecting plate 54 is movably connected in the notch and can rotate freely therein.

[0023] In order to further reduce the dust from entering the chamber 31, in the present embodiment, an inner dust-shielding plate 6 extending outward is further provided at the opening of the chamber 31, and an outer dust-shielding plate 41 extending inward and covering the outer side of the inner dust-shielding plate 6 is further provided on the dust cover 4. The inner dust-shielding plate 6 and the outer dust-shielding plate 41 may be fitted to each other or spaced apart. Regardless of the various contact modes, dust can be prevented from entering the chamber 31 through the gap between the box surface 2 and the dust cover 4. Furthermore, a slope 32 extending obliquely upward is provided at the bottom of the chamber 31, and dust that has entered the chamber 31 is not easily accumulated directly on the slope 32, thereby reducing the possibility of the inner display window 3 being blocked by dust.

[0024] In certain circumstances, the operator may need to directly read the reading of the electric energy meter in the box body 1. In this case, an external display window 42 may be fixedly provided on the inner side of the dust cover 4. Through the external display window 42, the specific reading on the inner display window 3 may be directly observed. However, due to the lack of obstruction, dust accumulation on the external display window 42 is inevitable. For this reason, after a period of use, when the inner display window 3 cannot be read normally from the external display window 42, the external display window 42 may be replaced directly by replacing the dust cover 4.

[0025] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
