Description

Technical Field

[0001] This utility model relates to the field of protective housing technology, specifically to a power meter with protective functions. Background Technology

[0002] Power meters are power measurement and control devices that provide solutions for power parameter measurement, power quality monitoring and analysis, and electrical equipment control. As an advanced, intelligent, and digital power grid front-end acquisition element, power meters are widely used in various control systems, SCADA systems and energy management systems, substation automation, community power monitoring, industrial automation, intelligent buildings, intelligent distribution cabinets, switch cabinets, and other equipment. They are characterized by convenient installation, simple wiring, and small engineering workload. Existing power meters are generally equipped with a housing, a display screen, and internal electronic components. The display screen is located on the outside of the housing, while the internal electronic components are located inside the housing. The housing is used to protect the internal electronic components, but the screen is generally relatively fragile and lacks protection, making it prone to damage.

[0003] Publication No. CN215297532U discloses a liquid crystal multi-functional power meter with a protective shell structure, including a protective shell, a spring a, a slider b, an anti-collision plate, and a connecting plate. The protective shell has internal grooves b located at both ends. Slider b and spring a are installed within the grooves b. A shock-absorbing column is installed at the outer end of slider b, and an anti-collision plate is installed at the outer end of the shock-absorbing column. A connecting plate is installed between the anti-collision plates. By changing the integrated protective plate structure to a chain structure composed of anti-collision plates and connecting plates, when the anti-collision plate or connecting plate is impacted, both the anti-collision plate and the connecting plate simultaneously contract to buffer the impact, preventing deformation at the connection between the anti-collision plate and the shock-absorbing column and tilting of the slider. This ensures the slider and the slide barrel are parallel, allowing the slider to smoothly enter the slide barrel and ensuring the spring can contract effectively, thus extending the service life of the protective shell and reducing maintenance costs. However, this patent still has the following problems in practical use:

[0004] Existing shock absorption and buffering methods mostly utilize springs or rubber materials. However, regardless of the material or component, they will age or corrode after long-term use, leading to a decrease in protective function and thus requiring replacement. The vibration damping elements in the aforementioned devices are not easy to replace, causing the protective effect to decrease over time. Existing single-layer instrument housings are prone to deformation after collisions, and such housings are even more difficult to replace or repair.

[0005] A power meter with protective functions is proposed to address the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a power meter with protective function, in order to solve the problems mentioned in the background art. Most of the existing shock absorption and buffering are achieved by using springs or rubber materials. However, no matter what kind of raw materials or parts are used, they will age or rust after long-term use, resulting in a decrease in the protective function, so they need to be replaced. The vibration damping elements in the above-mentioned devices are not easy to replace, which leads to a decrease in the protective effect over time. The existing single-layer shell of the meter is easy to deform after a collision, and this kind of shell is even more difficult to replace or repair.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a power meter with protective function, comprising a power meter body;

[0008] The main body of the power meter is provided with a protective component. The protective component includes a protective sleeve, four stepped strips are fixedly connected to the inner side of the protective sleeve, a rubber sleeve is fixedly connected to the outer side of the protective sleeve, a head cover is fixedly connected to the open side of the protective sleeve, a back shell is fixedly connected to the side of the rubber sleeve away from the head cover, a friction ring is fitted to the middle of the back shell, a rotating knob is fixedly connected to the middle of the friction ring, four arc-shaped rods are rotatably connected to the outer side of a section of the rotating knob inside the back shell, and a pin is rotatably connected to the end of the arc-shaped rod away from the rotating knob.

[0009] The main body of the power meter is fixedly connected to four positioning sleeves on the side near the back shell. The positioning sleeves penetrate the protective sleeve and the rubber sleeve. The end of the positioning sleeve is provided with a through hole, and the pin is inserted into the through hole.

[0010] One side of the headgear is provided with a shielding component.

[0011] Preferably, a circular hole is provided in the middle of the back shell, the friction ring is located inside the circular hole and fits against the inner wall of the circular hole, and the rotating button is rotatably connected to the rubber sleeve.

[0012] Preferably, the four arc-shaped rods are evenly distributed around the circumference, and the side of the back shell is evenly provided with through grooves, and the pin is slidably connected to the through grooves.

[0013] Preferably, the four stepped strips are evenly distributed and slidably connected to the stepped groove, and the protective sleeve is fitted over the outside of the main body of the power meter.

[0014] Preferably, the shielding component includes a mounting frame, a fitting strip is fixedly connected to the side of the mounting frame near the head cover, a glass plate is fixedly connected to the middle of the mounting frame, a clearance groove is provided at the bottom of the glass plate, and an annular magnetic sleeve is embedded on the side of the head cover near the mounting frame.

[0015] Preferably, a transparent plastic film can be adhered to the inside of the recessed groove.

[0016] Preferably, the interlocking strip is interlocked with the annular magnetic sleeve.

[0017] Compared with the prior art, the beneficial effects of this utility model are: This power meter with protective function can quickly replace the rubber sleeve by replacing the protective sleeve, thus effectively protecting the surface of the power meter body and preventing it from being deformed by direct impact, or its internal parts from being damaged by impact vibration. The specific details are as follows:

[0018] 1. By rotating the knob, the arc-shaped rod moves the pin, which is then pulled out of the positioning sleeve. At this point, by pulling the protective sleeve, the step strip can be pulled out of the step groove, thus achieving quick disassembly of the protective sleeve. This allows for quick replacement of the protective sleeve when it becomes worn due to long-term impact or aged due to environmental factors. The effective rubber sleeve can effectively protect the surface of the power instrument body, preventing it from being deformed by direct impact or its internal parts from being damaged by vibration.

[0019] 2. By fitting the mounting frame's interlocking strip with the annular magnetic sleeve, the glass plate can protect the LCD screen of the power meter's main body, preventing debris on the ground from directly impacting the LCD screen and causing damage. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1 - Figure 6 The present invention provides a technical solution: a power meter with protective function, comprising a power meter body 1;

[0029] The main body 1 of the power meter is equipped with a protective component 2. The protective component 2 includes a protective sleeve 201. Four stepped strips 203 are fixedly connected to the inner side of the protective sleeve 201. A rubber sleeve 202 is fixedly connected to the outer side of the protective sleeve 201. A head cover 211 is fixedly connected to the open side of the protective sleeve 201. A back cover 205 is fixedly connected to the side of the rubber sleeve 202 away from the head cover 211. A friction ring 208 is fitted and connected to the middle of the back cover 205. A rotating knob 207 is fixedly connected to the middle of the friction ring 208. 7. Four arc-shaped rods 209 are rotatably connected to the outer side of the back cover 205. The end of the arc-shaped rods 209 away from the rotating knob 207 is rotatably connected to the pin 210. The protective sleeve 201 fits into the casing of the power meter body 1. The protective sleeve 201 has sufficient ventilation holes and reserved wiring ports for the power meter body 1. The protective sleeve 201 and the casing of the power meter body 1 together form the double-layer outer shell of the power meter. The rotating knob 207 is polygonal at the outer end of the back cover 205 for easy application of force.

[0030] Among them, four positioning sleeves 206 are fixedly connected to the side of the main body 1 of the power meter near the back shell 205. The positioning sleeves 206 penetrate the protective sleeve 201 and the rubber sleeve 202. The end of the positioning sleeve 206 is provided with a through hole, and the pin 210 is inserted into the through hole.

[0031] Among them, a shielding component 3 is provided on one side of the head cover 211.

[0032] A circular hole is provided in the middle of the back cover 205. The friction ring 208 is located inside the circular hole and fits against the inner wall of the circular hole. The rotating button 207 is rotatably connected to the rubber sleeve 202. The friction of the friction ring 208 can restrict the position of the rotating button 207. Without sufficient external force, the rotating button 207 cannot rotate.

[0033] Four arc-shaped rods 209 are evenly distributed around the circumference, and through slots are evenly opened on the side of the back shell 205. The pin 210 is slidably connected to the through slot.

[0034] Four stepped strips 203 are evenly distributed and slidably connected to stepped grooves 204. The protective sleeve 201 is fitted onto the outside of the main body 1 of the power meter.

[0035] The shielding component 3 includes a mounting frame 301, a fitting strip 302 is fixedly connected to the side of the mounting frame 301 near the head cover 211, a glass plate 303 is fixedly connected to the middle of the mounting frame 301, a clearance groove 304 is provided at the bottom of the glass plate 303, and an annular magnetic sleeve 305 is embedded on the side of the head cover 211 near the mounting frame 301; the glass plate 303 is tempered glass.

[0036] A transparent plastic film can be adhered to the inside of the relief groove 304; the relief groove 304 can provide a pressing relief for the buttons of the power meter body 1, while the deformable transparent plastic film can protect them.

[0037] The interlocking strip 302 is interlocked with the annular magnetic sleeve 305; the interlocking strip 302 is a copper strip that can be interlocked with the annular magnetic sleeve 305 and is strongly magnetically attracted.

[0038] Working principle: Before using this type of power meter with protective functions, it is necessary to check the overall condition of the device to ensure that it can operate normally. Figure 1 - Figure 6 As shown, rotating the rotary knob 207 drives the friction ring 208 to rotate, and pulling the arc rod 209 causes the pin 210 to move. The pin 210 slides in the through groove and is simultaneously pulled out from the positioning sleeve 206. At this time, by pulling the protective sleeve 201, the step strip 203 can be pulled out from the step groove 204, thereby realizing the quick disassembly of the protective sleeve 201. When the rubber sleeve 202 is worn due to long-term collision or aged due to the environment, it can be replaced by replacing the protective sleeve 201. The effective rubber sleeve 202 can effectively protect the surface of the power instrument body 1, preventing it from being directly impacted and deformed, or its internal parts from being damaged by the vibration of the impact.

[0039] The friction of the friction ring 208 can restrict the position of the rotating knob 207, and the rotating knob 207 cannot rotate in the absence of sufficient external force.

[0040] By fitting the mounting frame 301's fitting strip 302 with the annular magnetic sleeve 305, the glass plate 303 can protect the LCD screen of the power meter body 1, preventing debris on the ground from directly impacting the LCD screen and causing damage.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
