Description

Technical Field

[0001] This utility model belongs to the field of electricity meter technology, specifically relating to an electricity meter with waterproof function. Background Technology

[0002] An electricity meter is an instrument used to measure electrical energy. It is also known as an electricity meter, fire meter, or kilowatt-hour meter. It is widely used in various electrical quantity measurement applications. Electricity meters are used in a variety of environments, including places with good conditions and places with harsh conditions. In such cases, it is necessary to use special electricity meters with waterproof function to improve their performance and reliability in complex environments.

[0003] Existing waterproof electricity meters typically have a waterproof casing on the outside of the meter. While this achieves a waterproof effect, there are still some problems in actual use. The wiring parts of the meter are still exposed, which makes it easy for water to enter during use. Furthermore, when used in a relatively humid environment for a long time, moisture can easily penetrate through the wiring parts, eventually causing short circuits or other related problems. Utility Model Content

[0004] In view of this, the present invention provides a waterproof electricity meter that effectively isolates external moisture through the coordinated operation of multiple waterproof components, ensuring stable operation of the electricity meter in humid environments and extending its service life.

[0005] To solve the above-mentioned technical problems, this utility model provides a waterproof electricity meter, including an electricity meter and a waterproof mechanism disposed at its terminals. The waterproof mechanism includes a fixed plate disposed on one side of the electricity meter terminals, a movable insert plate movably inserted into the side of the fixed plate near the electricity meter terminals, an arc-shaped groove being provided at each wire hole near the electricity meter terminals between the fixed plate and the movable insert plate, waterproof rubber sealing gaskets being provided on the opposite inner surfaces of the movable insert plate and the fixed plate, and a waterproof rubber sleeve being provided at each wire hole of the electricity meter terminals. The electricity meter is also provided with a limiting component for limiting the movable insert plate. That is, through the coordinated cooperation of multiple waterproof components, external moisture is effectively isolated, ensuring the stable operation of the electricity meter in a humid environment and extending its service life.

[0006] The waterproof mechanism also includes waterproof rubber plugs that are respectively set on the inner side of the movable plug plate near the opening of each wire terminal of the electricity meter. The waterproof rubber plugs are movably inserted into the corresponding wire terminal openings, thus achieving the purpose of multi-layer waterproofing.

[0007] The limiting assembly includes fixed boxes symmetrically arranged on the lower sides of both ends of the energy meter. Each end of the movable plug plate is provided with a ratchet plate near each fixed box. The ratchet plate is movably inserted into the adjacent fixed box on the same side. The outer side of each fixed box is rotatably connected with a pawl. The outer wall of the inner cavity of each fixed box is provided with a spring piece. The spring piece abuts against the pawl located in the same fixed box, thereby realizing the quick installation and locking of the movable plug plate.

[0008] The limiting assembly also includes limiting posts respectively disposed in the fixed box. The limiting posts are in active contact with the inner side of the pawl located in the same fixed box, thereby limiting the range of movement of the pawl.

[0009] The limiting assembly also includes levers respectively located on the outside of the pawl, making it easier for operators to perform operations.

[0010] It also includes an ejection assembly, which includes fixed cylinders respectively set in the fixed box. Each fixed cylinder is slidably connected to a sliding cylinder. Each sliding cylinder is provided with a spring between its inner cavity and the inner cavity of its fixed cylinder. The outer end of the sliding cylinder is in contact with the inner end of the adjacent ratchet plate on the same side, thereby realizing the rapid ejection of the movable insert plate.

[0011] An arc-shaped groove is provided between the waterproof rubber sealing gaskets at each wire hole near the terminal of the electricity meter to ensure a tighter fit with the cable.

[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0013] 1. After the electricity meter wiring is completed, the movable plug and the fixed plate are plugged in. Both the fixed plate and the movable plug have arc-shaped grooves near each wire hole, and waterproof rubber sealing gaskets are provided on their opposite inner surfaces. When the two are fastened together, the waterproof rubber sealing gaskets are squeezed and deformed, tightly adhering to the cable surface, effectively preventing moisture intrusion. At the same time, each wire hole of the electricity meter terminal is also equipped with a waterproof rubber sleeve. When installing the cable, it must be inserted into the rubber sleeve before connection, further enhancing the overall waterproof performance. In addition, a waterproof rubber plug is provided on the inner surface of the movable plug near the opening of the pressure end, which can form a movable plug with the opening of the pressure end, playing a secondary sealing role. Through the coordinated cooperation of the above waterproof mechanism components, external moisture is effectively isolated, ensuring the stable operation of the electricity meter in a humid environment and extending its service life.

[0014] 2. When the movable insert plate and the fixed plate are engaged, the ratchet plate will insert into the corresponding fixed box. The ratchet plate inside the fixed box continuously pushes the pawl, causing it to tilt upwards against the elastic force of the spring. When the ratchet groove of the ratchet plate moves to the position of the pawl, the pawl resets under the action of the spring force and locks into the ratchet groove, thereby achieving the limiting and fixing of the movable insert plate. When it is necessary to open the movable insert plate, simply rotate the pawl counterclockwise using the lever to disengage it from the ratchet groove. At this time, the movable insert plate can be removed.

[0015] 3. Under the action of the spring's rebound force, the sliding cylinder pushes the ratchet plate, which in turn drives the movable insert plate outward, realizing the quick disassembly of the movable insert plate. The operation is convenient and reliable. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0022] This embodiment provides a waterproof energy meter, such as... Figure 1-4The device includes an electricity meter 100 and a waterproof mechanism installed at its terminals. The waterproof mechanism includes a fixing plate 200 located on one side of the electricity meter 100's terminals. A movable insert plate 201 is movably inserted into the fixing plate 200 near the electricity meter 100's terminals. An arc-shaped groove is provided at each wire hole near the electricity meter 100's terminals between the fixing plate 200 and the movable insert plate 201. Waterproof rubber sealing gaskets 202 are provided on the opposing inner surfaces of the movable insert plate 201 and the fixing plate 200. Each wire hole of the terminal of the 100 is provided with a waterproof rubber sleeve 204. The 100 of the electricity meter is also provided with a limiting component for limiting the movable plug 201. The waterproof mechanism also includes waterproof rubber plugs 203 respectively set on the inner side of the movable plug 201 near the opening of each wire terminal of the electricity meter 100. The waterproof rubber plugs 203 are movably inserted into the corresponding wire terminal openings. An arc-shaped groove is opened between the two waterproof rubber sealing gaskets 202 near each wire hole of the terminal of the electricity meter 100.

[0023] After the electricity meter is wired, the movable plug plate 201 is inserted into the fixed plate 200. Both the fixed plate 200 and the movable plug plate 201 have arc-shaped grooves near each wire hole, and waterproof rubber sealing gaskets 202 are provided on their opposite inner surfaces. When the two are engaged, the waterproof rubber sealing gaskets 202 are compressed and deformed, tightly adhering to the cable surface and effectively preventing moisture intrusion. At the same time, each wire hole of the electricity meter terminal is also provided with a waterproof rubber sleeve 204. The cable must be inserted into the rubber sleeve before connection, further enhancing the overall waterproof performance. In addition, a waterproof rubber plug 203 is provided on the inner surface of the movable plug plate 201 near the opening of the wire end. It can form a movable insertion with the opening of the wire end, playing a secondary sealing role. Through the coordinated cooperation of the above waterproof mechanism components, external moisture is effectively isolated, ensuring the stable operation of the electricity meter in a humid environment and extending its service life.

[0024] like Figure 1-4 As shown, the limiting assembly includes fixed boxes 300 symmetrically arranged on the lower sides of both ends of the energy meter 100. Each end of the movable insert plate 201 is provided with a ratchet plate 301 near each fixed box 300. The ratchet plate 301 is movably inserted into the adjacent fixed box 300 on the same side. A pawl 302 is rotatably connected to the outer side of each fixed box 300. A spring piece 304 is provided on the outer wall of the inner cavity of each fixed box 300. The spring piece 304 abuts against the pawl 302 located in the same fixed box 300. The limiting assembly also includes limiting posts 303 respectively arranged in the fixed boxes 300. The limiting posts 303 are movably contacted with the inner side of the pawl 302 located in the same fixed box 300. The limiting assembly also includes a lever plate 305 respectively arranged on the outer side of the pawl 302.

[0025] When the movable insert plate 201 is engaged with the fixed plate 200, the ratchet plate 301 will be inserted into the corresponding fixed box 300. The ratchet plate 301, which enters the fixed box 300, continuously pushes the pawl 302, causing it to tilt upwards against the elastic force of the spring piece 304. When the ratchet groove of the ratchet plate 301 moves to the position of the pawl 302, the pawl 302 is reset under the action of the spring force of the spring piece 304 and is locked into the ratchet groove, thereby achieving the limiting and fixing of the movable insert plate 201. When it is necessary to open the movable insert plate 201, simply rotate the pawl 302 counterclockwise through the lever 305 to disengage it from the ratchet groove, thus achieving quick disassembly and installation.

[0026] like Figure 1-4 As shown, it also includes an ejection assembly, which includes fixed cylinders 400 respectively disposed in the fixed box 300. Each fixed cylinder 400 is slidably connected to a sliding cylinder 401. Each sliding cylinder 401 is provided with a spring 402 between itself and the inner cavity of the fixed cylinder 400. The outer end of the sliding cylinder 401 is in contact with the inner end of the adjacent ratchet plate 301 on the same side.

[0027] When it is necessary to open the movable insert plate 201, simply rotate the pawl 302 counterclockwise using the lever 305 to disengage it from the ratchet groove. At this time, the sliding cylinder 401 pushes the ratchet plate 301 under the action of the spring 402's rebound force, thereby driving the movable insert plate 201 to push outward, achieving quick disassembly. The operation is convenient and reliable.

[0028] The working principle of the waterproof energy meter provided by this utility model is as follows: After the energy meter is wired, the movable plug 201 is inserted into the fixed plate 200. Both the fixed plate 200 and the movable plug 201 have arc-shaped grooves near each wire hole, and waterproof rubber sealing gaskets 202 are provided on their opposite inner surfaces. When the two are engaged, the waterproof rubber sealing gaskets 202 are compressed and deformed, tightly adhering to the cable surface, effectively preventing moisture intrusion. Simultaneously, a waterproof rubber sleeve 204 is also provided at each wire hole of the energy meter's wiring terminal. The cable must be inserted into this rubber sleeve before connection, further enhancing the overall waterproof performance. In addition, a waterproof rubber plug 203 is provided on the inner surface of the movable plug 201 near the wire end opening, which can form a movable insertion with the wire end opening, providing a secondary sealing effect. Through the coordinated operation of the various components of the above-mentioned waterproof mechanism, external moisture is effectively isolated, ensuring the energy meter's waterproof performance. Stable operation in humid environments extends service life. When the movable insert plate 201 engages with the fixed plate 200, the ratchet plate 301 inserts into the corresponding fixed box 300. The ratchet plate 301, inside the fixed box 300, continuously pushes the pawl 302, causing it to overcome the elastic force of the spring piece 304 and tilt upwards. When the ratchet groove of the ratchet plate 301 moves to the position of the pawl 302, the pawl 302 resets under the action of the spring piece 304's rebound force and engages in the ratchet groove, thus achieving [the desired operation]. The movable insert plate 201 is fixed in place. During this process, the ratchet plate 301 will also push the sliding cylinder 401 to overcome the elastic force of the spring 402 and retract to store energy. When it is necessary to open the movable insert plate 201, simply rotate the pawl 302 counterclockwise through the lever 305 to disengage it from the ratchet groove. At this time, the sliding cylinder 401 pushes the ratchet plate 301 under the action of the spring 402's rebound force, thereby driving the movable insert plate 201 to push outward, achieving quick disassembly. The operation is convenient and reliable.

[0029] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
