Description

Technical Field

[0001] The utility model relates to the technical field of electrical instrument installation, in particular to an electric power meter which is easy to install. Background Art

[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. They are widely used in various control systems, SCADA systems, energy management systems, substation automation, residential power monitoring, industrial automation, smart buildings, smart distribution cabinets, switchgear, and other equipment. Power meters are typically installed with a cabinet door. The meter body is inserted into a pre-cut hole in the cabinet door, and then mounted inside the cabinet door using clips to secure the meter to the back of the cabinet door. For example, Chinese patent No. CN20827035U discloses a three-phase multifunctional power meter that secures the meter with clips installed on both sides of the housing, which then abut against the cabinet door. The inventors discovered during use that while this method can secure the meter, for some multifunctional power meters with complex functions and large specifications, the clips are heavy and cannot withstand the heavy weight for long periods of time, potentially causing them to loosen or even break. This results in unstable meter fixation and requires frequent clip replacement, which is both troublesome and increases the installation cost of the power meter. Utility Model Content

[0027] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0028] Example

[0029] As mentioned in the background technology, both the existing technology and the technology in the existing patent use the form of installing clips on both sides of the outside to fix the instrument body and the cabinet door. Although the method is relatively simple and convenient, it has many defects. For some heavier instruments, the use of clips can also complete the fixation, but it is not suitable for long-term use. If the clips bear a heavy load for a long time, they may become loose or even break, so they need to be replaced frequently. Therefore, the inventors have made improvements on the existing technology and designed a new instrument installation method to overcome the above problems. The following is a detailed explanation with reference to the diagrams.

[0030] This embodiment provides an easy-to-install power meter. Figure 1, including an instrument body 1, the outer edge of the instrument body 1 is movably sleeved with a mounting bracket 2. The difference between this solution and the prior art is that the prior art basically installs two clips on the side of the instrument body 1 and is tightly fixed to the cabinet door 11, while this solution adopts a sleeve installation form. The mounting bracket 2 wraps the instrument body 1, making the installation of the two more stable, and the mounting bracket 2 and the instrument body 1 can be fixed in multiple positions, so that the distance between the mounting bracket 2 and the front end surface of the instrument body 1 can be adjusted, and then it can be fixed to cabinet doors 11 of different thicknesses. Specifically, the mounting bracket 2 is installed with multiple groups of flexible card blocks 7 on one side close to the back of the instrument body 1, combined with Figure 2 , and the flexible buckle is located at the four corners of the mounting bracket 2, and is connected to the power meter through multiple teeth 8, and the direction of the teeth 8 should ensure that the flexible buckle can be restricted from moving toward the back of the meter body 1 without bending the flexible buckle. During installation, push the mounting bracket 2 forward, and then the flexible buckle can move forward along the teeth 8 until the mounting bracket 2 abuts against the cabinet door 11. During disassembly, bend the flexible buckle upward to separate the teeth 8, and then pull the mounting bracket 2 backward.

[0031] Based on the above structure, combined Figure 3 A slide bar 9 is provided on the side of the mounting frame 2 close to the instrument body 1, and a slide groove 10 for the slide bar 9 to slide is opened along the width direction of the instrument body 1. Two slide bars 9 are provided on both sides of the four corners where the mounting frame 2 contacts the instrument body 1, and two corresponding slide grooves 10 are opened, which can make the fixation of the mounting frame 2 and the instrument body 1 more stable and can guide the movement of the mounting frame 2.

[0032] In this embodiment, in order to enable the mounting frame 2 to be elastically connected to the cabinet door 11 and prevent the cabinet door 11 and the mounting frame 2 from causing significant wear, support frames 3 are installed on both sides of the mounting frame 2, which can abut against the inner surface of the cabinet door 11 on which the instrument body 1 is installed. Specifically, the support frame 3 includes a fixed end 31 arranged near the edge of the instrument body 1, and in order to improve the fixing stability of the support frame 3 and the cabinet door 11, the fixed end 31 is installed with a fastening bolt 33, and the extending direction of the fastening bolt 33 is consistent with the moving direction of the mounting frame 2. The fastening bolt 33 can penetrate the fixed end 31 and abut against the cabinet door 11. The fastening bolt 33 can press the fixed end 31 and the cabinet door 11 tightly.

[0033] On the basis of the above structure, the fixed end 31 is connected to the supporting end 32, and the supporting end 32 can abut against the inner surface of the cabinet door 11 on which the instrument body 1 is installed. The end of the supporting end 32 away from the fixed end 31 extends toward the front of the instrument body 1 and exceeds the support frame 3, and uses elastic plastic material, so that when fixed to the cabinet door 11, only the extended end of the supporting end 32 abuts against the cabinet door 11, and has a certain elasticity and can be pressed against the cabinet door 11, reducing the contact area with the cabinet door 11, and is elastically fixed, reducing the wear of the supporting end 32 and the cabinet door.

[0034] It should be noted that the two support frames 3 are centrally symmetrical with respect to the back of the power meter. Figure 3 That is, the fixed ends 31 of the two support frames 3 are respectively located at the upper end and the lower end of the mounting frame 2, and the connected support ends 32 extend in opposite directions, which can ensure the balance of the instrument body 1 when it is fixed.

[0035] In order to further support the instrument body 1, one of the main design points of this scheme is that the bottom of the mounting frame 2 is connected to a mounting assembly 4, and a support rod 5 is installed on the side of the bottom surface of the mounting assembly 4 away from the support frame 3. The support rod 5 is tilted and extends toward one side of the support frame 3. The specific mounting assembly 4 includes a mounting plate 41 connected to the bottom of the mounting frame 2, the mounting plate 41 extends toward the back of the instrument body 1 and is in contact with the instrument body 1. The mounting plate 41 is provided with a mounting seat 42 away from the bottom surface of the support frame 3, and the support rod 5 is fixedly connected to the mounting seat 42, thereby realizing the inclined installation of the support rod 5, and the top end of the support rod 5 can support the mounting plate 41 through the mounting seat 42, thereby supporting the rear end of the instrument body 1.

[0036] On the basis of the above structure, a support plate 6 is installed at the end of the support rod 5, which can abut against the inner surface of the cabinet door 11 on which the instrument body 1 is installed. Moreover, the side of the support plate 6 close to the front end of the instrument body 1 is perpendicular to the moving direction of the mounting frame 2, so that the support plate 6 can be parallel to the cabinet door 11, and then can fit with the cabinet door 11. The front end surface of the support plate 6 is installed with an elastic pad with greater friction, which can increase the friction between the cabinet door 11 and the support effect. When the instrument body 1 is installed, Figure 4 As shown, insert the instrument body 1 into the hole of the cabinet door 11, install the mounting bracket 2 on the outside of the instrument body 1 on the inside of the cabinet door 11, and push it toward the cabinet door 11 until the end of the support end 32 extends and contacts the cabinet door 11, continue to push, squeeze the support end 32, and until the support plate 6 is against the cabinet door 11 to complete the fixation.
