Description

Technical Field

[0001] This utility model relates to the field of electricity meter technology, specifically to a highly protective electricity meter housing with a quick-installation wall-mounting structure. Background Technology

[0002] Currently, the existing electricity meter casings on the market present many inconveniences in actual installation and use. Traditional wall-mounted installation methods for electricity meter casings mostly use bolts for direct fixing, which not only requires pre-drilling holes in the wall or mounting surface, making the installation process cumbersome and consuming a lot of manpower and time, but also makes disassembly more troublesome during subsequent maintenance or replacement. At the same time, the protective performance of existing electricity meter casings varies, with some casings performing poorly in terms of waterproofing, dustproofing, and resistance to external impacts. Especially in some harsh industrial environments or outdoor scenarios, this can affect the normal operation of electricity meters and may even cause safety hazards. Therefore, we propose a highly protective electricity meter casing with a quick-install wall-mounting structure.

[0003] In current electrical installation technology, electricity meter casings are generally installed using a wall-mounted method. However, in actual use, this installation structure is prone to loosening and shaking due to external forces or prolonged vibration. Furthermore, when multiple electricity meters are installed side by side on the same slide rail, adjacent meters are highly susceptible to collisions during installation or operation due to the lack of effective isolation or buffering mechanisms. Existing electricity meter casings do not have dedicated anti-collision protection structures around their perimeter. This makes it easy for adjacent meters to come into contact and collide when multiple sets of meters are installed simultaneously. In addition, due to limited installation space or improper operation, the meter casings may also collide unnecessarily with the inner wall of the electrical box, thereby affecting the safety and stability of the equipment.

[0004] In view of this, we propose a highly protective energy meter housing with a quick-install wall-mounting structure to solve the existing problems. Utility Model Content

[0005] The purpose of this utility model is to provide a highly protective energy meter housing with a quick-installation wall-mounting structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-protection energy meter housing with a quick-installation wall-mounting structure, comprising an inner wall of an electrical box, a back plate, and a protective shell, wherein an installation rail is fixedly installed on the front of the inner wall of the electrical box, and the installation rail has a U-shaped groove structure;

[0007] A mounting bracket is fixedly installed on the back of the back plate. The mounting bracket is a horizontal bar structure, and side plates are fixedly installed on both sides of the mounting bracket. Fixing clamps are fixedly installed on both sides of the bottom of the mounting bracket, and the fixing clamps are plugged into the mounting rail.

[0008] A protective shell is fixedly installed on the front of the back plate. The protective shell has a display window inside the front and an observation window above the display window.

[0009] Preferably, the total width of the two side panels is greater than the width of the back panel, and the front-to-back length of the side panels is greater than the total front-to-back length of the back panel and the protective shell.

[0010] Preferably, the two side panels are installed in a figure-eight shape, with the side of the side panel with the wider opening facing the front of the protective shell, and a distance of three to five centimeters is provided between the side panel and the back panel and the protective shell.

[0011] Preferably, the bottom of the fixing clamp has a barb-shaped structure, and anti-slip strips are fixedly installed at equal intervals at the contact positions between the back of the fixing clamp and the inner wall of the mounting track, wherein the anti-slip strips are installed longitudinally.

[0012] Preferably, the protective shell is made of ABS engineering plastic and has reinforcing ribs on the inner wall.

[0013] Preferably, the display window is made of transparent polycarbonate sheet and has a waterproof rubber ring around the edge.

[0014] Preferably, the observation window is connected to the protective shell by a hinge and is equipped with a magnetic latch, and a dustproof rubber ring is fitted at the contact position between the observation window and the protective shell.

[0015] Preferably, the bottom of the protective shell is provided with a wire harness mounting groove, and a dustproof rubber ring is installed in the wire harness mounting groove.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This utility model utilizes a fixing clamp at the bottom of the mounting frame. The hook-shaped structure at the bottom of the fixing clamp abuts against the inner wall of the mounting track, thereby enabling the device to be quickly mounted and installed. At the same time, the anti-slip strips on the surface of the fixing clamp prevent the device from sliding horizontally within the mounting track, thus avoiding collisions with adjacent electricity meters.

[0018] This invention, by designing the side panels in a V-shape, effectively prevents adjacent electricity meters from colliding and being damaged during installation or use. Furthermore, because the front end of the side panel protrudes from the protective shell, this structure also provides protection when the electrical box is closed, preventing accidental impacts to the front of the protective shell, thereby further enhancing overall safety and durability.

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] like Figure 1 - Figure 4 As shown, the present invention proposes a high-protection energy meter housing with a quick-installation wall-mounting structure, including an electrical box inner wall 1, a back plate 2, and a protective shell 3. An installation rail 101 is fixedly installed on the front of the electrical box inner wall 1, and the installation rail 101 has a U-shaped groove structure. The U-shaped groove structure can form a stable plug-in fit with the fixing clamp 203, providing precise installation guidance for the back plate 2, while realizing rapid positioning and load-bearing support, thereby providing a basic structure for the quick-installation wall-mounting function.

[0026] A mounting bracket 202 is fixedly installed on the back of the back plate 2. The mounting bracket 202 is a horizontal bar structure, and side plates 201 are fixedly installed on both sides of the mounting bracket 202. Fixing clamps 203 are fixedly installed on both sides of the bottom of the mounting bracket 202. The fixing clamps 203 are plugged into the mounting rail 101. The horizontal bar-shaped mounting bracket 202 can enhance the overall structural strength of the back plate 2. The side plates 201 can provide lateral protection for the protective shell 3. The plugging and connecting of the fixing clamps 203 and the mounting rail 101 enables the quick disassembly and assembly of the energy meter shell, greatly improving the installation efficiency.

[0027] A protective shell 3 is fixedly installed on the front of the back panel 2. The protective shell 3 has a display window 301 inside the front of the protective shell 3, and an observation window 302 is provided above the display window 301. The protective shell 3 provides physical protection for the internal electrical components. The display window 301 is used to read the power data intuitively, and the observation window 302 makes it easy to check the status of the internal components without disassembling the shell, thus achieving a combination of protection and maintenance convenience.

[0028] Furthermore, the total width of the two side plates 201 is greater than the width of the back plate 2, and the front-to-back length of the side plates 201 is greater than the total front-to-back length of the back plate 2 and the protective shell 3. The size of the side plates 201 is greater than the size of the core components, which can effectively block external lateral impacts and collisions with foreign objects, forming an outer protective barrier and preventing the back plate 2 and the protective shell 3 from being directly subjected to force.

[0029] Furthermore, the two side panels 201 are installed in a figure-eight shape, with the side of the side panel 201 with the wider opening facing the front of the protective shell 3. There is a distance of three to five centimeters between the side panel 201 and the back panel 2 and the protective shell 3. The figure-eight layout can disperse the frontal impact force, and the inclined structure guides the external force to be transmitted to both sides. The spacing design reserves buffer space, and the reserved gap can form an air convection channel to assist in heat dissipation and reduce vibration transmission.

[0030] Furthermore, the bottom of the fixing clamp 203 has a barbed structure, and anti-slip strips are fixedly installed at equal intervals at the contact positions between the back of the fixing clamp 203 and the inner wall of the mounting track 101. The anti-slip strips are installed longitudinally, and the barbed structure prevents accidental detachment after installation. The longitudinal anti-slip strips increase the friction with the inner wall of the track, providing double protection for the structural stability after insertion and avoiding loosening caused by vibration.

[0031] Furthermore, the protective shell 3 is made of ABS engineering plastic and has reinforcing ribs on the inner wall. ABS material has both impact resistance and corrosion resistance, making it suitable for complex outdoor environments. The inner wall reinforcing ribs can improve the overall rigidity of the protective shell 3 without increasing its thickness, preventing deformation from damaging internal components.

[0032] Furthermore, the display window 301 is made of transparent polycarbonate sheet with a waterproof rubber ring around the edge. The transparent polycarbonate sheet ensures clear data reading while providing impact resistance. The waterproof rubber ring fills the gap between the window and the housing, effectively preventing rainwater and moisture from entering and improving the protection level of the protective housing 3.

[0033] Furthermore, the observation window 302 is connected to the protective shell 3 by a hinge and is equipped with a magnetic latch. A dustproof rubber ring is fitted at the contact position between the observation window 302 and the protective shell 3. The hinge connection allows the window to be opened flexibly, the magnetic latch ensures a tight fit when closed, and the dustproof rubber ring prevents dust from entering the interior through gaps, ensuring cleanliness for long-term use.

[0034] Furthermore, the bottom of the protective housing 3 is provided with a wire harness mounting groove, and a dustproof rubber ring is installed in the wire harness mounting groove. The wire harness mounting groove can standardize the cable routing and avoid messy tangling. The dustproof rubber ring can fix the wire harness and prevent dust from entering from the cable inlet, thus improving the overall sealing performance.

[0035] Working principle: After the core components of the electricity meter are installed inside the protective shell 3, the connecting wire harness is arranged and fixed in an orderly manner through the specially designed wire harness installation groove at the bottom of the protective shell 3. After the entire device is assembled, the fixing plate 203 is inserted into the preset installation track 101. The barbed structure at the bottom of the fixing plate 203 makes it closely contact the inner wall of the installation track 101. At the same time, with the help of several protective strips on the surface of the fixing plate 203, it is ensured that the protective shell 3, the back plate 2 and the mounting bracket 202 can be firmly and stably installed on the installation track 101.

[0036] When multiple electricity meters need to be installed, the side plates 201 on the sides of two adjacent electricity meters will abut against each other. When these side plates 201 come into contact, they can buffer each other, thereby effectively preventing direct collision between the protective shells 3 and avoiding damage.

[0037] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
