Description

Technical Field

[0001] This utility model relates to the field of meter wiring clamp technology, and in particular to a universal meter wiring clamp. Background Technology

[0002] A meter wiring clamp is a component used for wiring meters. It is made of a metal material with good conductivity and a certain strength, which not only ensures good current conduction performance, but also can withstand a certain degree of external force without deformation, ensuring a stable connection with the wire during long-term use. It also has a special metal plating on the surface to enhance its oxidation resistance and corrosion resistance.

[0003] A search revealed Chinese Patent Publication No. CN219625579U, which discloses a universal electricity meter clamp, relating to the field of electricity meter clamp technology. The clamp includes a main body with an adjustment mechanism on its surface. This mechanism includes a control rod and a connecting rod. The control rod is slidably connected to the upper surface of the clamp body, and the connecting rod passes through and is slidably connected to the clamp body. Through the coordinated arrangement of the clamp body, adjustment mechanism, limiting mechanism, female component, and male component, the size of the main wire cavity can be adjusted according to the size of the main wire. This effectively avoids insufficient clamping force when clamping a small main wire due to the inability to adjust the size of the main wire cavity, further ensuring the stability of the main wire clamping and improving the applicability of the device. However, in existing clamps, the main wire cavity formed between the inner wall of one side of the clamp seat and the clamping block is a fixed size and cannot be adjusted, requiring the search for a suitable clamp size to match the main wire, thus reducing the applicability of the clamp. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a universal meter clamp, which aims to improve the problem that the existing clamp cannot be adjusted according to the size of the main line, resulting in the need to find a clamp of a suitable size to match the main line, thus reducing the applicability of the clamp.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a universal meter wiring clamp, comprising a base, two hinges fixedly connected to the top rear side of the base, a top seat fixedly connected to the top of the two hinges, a top cover fixedly connected to the middle rear side of the top seat, a fixing block fixedly connected to the bottom inner side of the base, a threaded rod threadedly connected to the top of the fixing block, a bolt threadedly connected to the middle outer wall of the threaded rod, a cover plate threadedly connected to the lower outer wall of the threaded rod, wire release plates fixedly connected to both the left and right sides of the base, multiple springs fixedly connected to the rear inner side of the base, pressure plates fixedly connected to the front sides of each of the multiple springs, and locking mechanisms provided on both the left and right sides of the top seat.

[0006] The above technical solution involves connecting a fixed block to a threaded rod. Rotating the bolt in the middle of the threaded rod causes the cover plate, which is threaded to the threaded rod, to move up and down. When a larger main line is placed on the pay-off plate, the spring uses its own elastic potential energy to push the pressure plate, applying appropriate squeezing force according to the thickness of the main line. This allows the connector clamp to adapt to main lines of different sizes, thus improving the applicability of the connector clamp.

[0007] As a further description of the above technical solution:

[0008] The locking mechanism includes two buckles. The left sides of the two buckles are fixedly connected to the left and right sides of the top base. Card boxes are fixedly connected to the left and right sides of the base. Multiple springs are fixedly connected to the bottom inner side of the two card boxes. A support plate is fixedly connected to the top of the multiple springs. Grooves are provided on the front and rear sides of the two card boxes. Pressing blocks are provided inside the multiple grooves.

[0009] The above technical solution achieves the following: when the device is closed and fixed, the buckle is inserted into the card box, and the squeezing block in the groove applies a certain pressure to the buckle during the locking process. When the top seat needs to be opened, the elastic potential energy of the second spring is released, which can push the support plate and make the buckle pop out of the card box, thereby realizing the ease of opening and closing operation and improving work efficiency.

[0010] As a further description of the above technical solution:

[0011] A fixing plate is threadedly connected to the middle of the outer wall of the threaded rod, and the fixing plate is of a smooth design.

[0012] Through the above technical solution, the fixing plate in the middle of the outer wall of the threaded rod is designed with a smooth shape, which can avoid the bolt and the cover plate being too tightly fitted, and facilitate the rotation of the bolt.

[0013] As a further description of the above technical solution:

[0014] The base is fixedly connected to a connecting plate at its bottom, and threaded holes are provided at the four corners of the top of the connecting plate for fixing it to the wall.

[0015] The above technical solution involves threaded holes at the bottom connecting plate and the four corners at the top of the base.

[0016] As a further description of the above technical solution:

[0017] Each of the multiple threaded holes has a screw threaded into its interior, and each of the multiple screws has a cap fixedly attached to its top.

[0018] Through the above technical solution, the cap on the top of the screw not only makes the connection more secure, but also prevents the screw from loosening or being corroded to a certain extent, ensuring the stability of the wiring clamp after installation.

[0019] As a further description of the above technical solution:

[0020] A second fixing plate is fixedly connected to the rear side of the top cover, and a warning sign is fixedly connected to the rear side of the second fixing plate.

[0021] Through the above technical solution: the second fixing plate on the rear side of the top cover is connected to the warning sign, which serves to warn and remind that there is electricity.

[0022] As a further description of the above technical solution:

[0023] A lamp holder is fixedly connected to the top rear side of the top seat, and an alarm light is fixedly connected to the rear side of the lamp holder.

[0024] Through the above technical solution, the alarm light on the lamp holder at the top rear side of the top bracket can sound an alarm when the main line loses power.

[0025] As a further description of the above technical solution:

[0026] A handle is fixedly connected to the top rear side of the top seat, and multiple anti-slip posts are fixedly connected to the front side of each of the multiple pressure plates.

[0027] Through the above technical solution: the handle on the top rear side of the top seat makes it easy to pull the top seat and facilitates operation; the multiple anti-slip posts on the front side of the multiple pressure plates can enhance the clamping effect on the main line and ensure the stability of the main line connection.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the fixing block is threadedly connected to the threaded rod. By rotating the bolt in the middle of the threaded rod, the cover plate threadedly connected to the threaded rod can move up and down. When a larger main line is placed behind the wire feeding plate, the spring uses its own elastic potential energy to push the pressure plate and apply appropriate squeezing force according to the thickness of the main line. This enables the wire clamp to effectively adapt to main lines of different sizes and improves the applicability of the wire clamp.

[0030] 2. In this utility model, when the device is closed and fixed, the buckle is inserted into the card box, and the squeezing block in the groove applies a certain pressure to the buckle during the locking process. When the top seat needs to be opened, the elastic potential energy of the second spring is released, which can push the support plate and make the buckle pop out of the card box, thereby realizing the simplicity of the opening and closing operation and improving work efficiency.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0039] Reference Figure 1 and Figure 4 This utility model provides an embodiment of a universal electricity meter clamp, including a base 1. Two hinges 3 are fixedly connected to the top rear side of the base 1. A top seat 4 is fixedly connected to the top of the two hinges 3, allowing the top seat 4 to be easily opened. A top cover 5 is fixedly connected to the middle rear side of the top seat 4. A fixing block 6 is fixedly connected to the bottom inner side of the base 1. A threaded rod 7 is threadedly connected to the top of the fixing block 6. A bolt 8 is threadedly connected to the middle outer wall of the threaded rod 7. A cover plate 9 is threadedly connected to the lower end of the outer wall of the threaded rod 7. The bolt 8 can be rotated to open the cover plate. This allows the cover plate 9 to move downwards and adjust its height according to the size of the main line. The left and right sides of the base 1 are fixedly connected to the wire feeding plate 10. The rear side of the interior of the base 1 is fixedly connected to multiple springs 11. The front side of each spring 11 is fixedly connected to a pressure plate 12. When a larger main line needs to be fixed, the wire feeding plate 10 is placed in. The elastic potential energy of the springs 11 allows the wire to be adjusted according to the thickness of the main line. The pressure plate 12 in front of the springs 11 can squeeze the main line to make it stable. The left and right sides of the top seat 4 are provided with a locking mechanism 2.

[0040] Specifically, two hinges 3 on the top rear side of the base 1 are connected to the top seat 4. The hinges 3 facilitate the opening and closing of the top seat 4. The top cover 5 in the middle of the rear side of the top seat 4 is used to prevent the internal structure from being too high. At the bottom inner side of the base 1, the fixing block 6 is threadedly connected to the threaded rod 7. The bolt 8 in the middle of the threaded rod 7 can be rotated, thereby driving the cover plate 9 threadedly connected to it to move up and down. The height can be adjusted according to the size of the main line. The cable trays 10 on the left and right sides of the base 1 provide a place for the main line. The multiple springs 11 on the rear side of the base 1 and the pressure plate 12 connected to the front side can adaptively adjust according to the thickness of the main line. When a larger main line is placed in the cable tray 10, the elastic potential energy of the springs 11 takes effect, so that the pressure plate 12 can generate appropriate squeezing force on the main line to ensure the stability of the main line. This effectively improves the adaptability and support of the connector to main lines of different sizes.

[0041] Reference Figure 3 and Figure 5The locking mechanism 2 includes two latches 201. The left sides of the two latches 201 are fixedly connected to the left and right sides of the top seat 4. The left and right sides of the base 1 are fixedly connected to the card box 202 for locking the card box 202. The bottom inner side of the two card boxes 202 is fixedly connected to multiple springs 203. The top of the multiple springs 203 is fixedly connected to the support plate 204. When not locking, the elastic potential energy of the springs 203 causes the springs 203 and the support plate 204 on the springs 203 to pop out the latches 201. The front and rear sides of the two card boxes 202 are provided with grooves 205. The interior of the multiple grooves 205 is provided with pressing blocks 206 for pressing the latches 201.

[0042] Specifically, the left sides of the two buckles 201 are fixed to the left and right sides of the top seat 4, respectively, while the left and right sides of the base 1 are provided with card boxes 202. The buckles 201 and card boxes 202 cooperate with each other for fixation. When the multiple springs 203 at the bottom of the inner side of the card box 202 and the support plate 204 connected to the top are engaged, the buckles 201 can be popped out by the elastic potential energy of the springs 203. Multiple grooves 205 are opened on the front and back sides of the two card boxes 202. The grooves 205 are provided with pressing blocks 206. The pressing blocks 206 are used to press the buckles 201 when engaged, thereby realizing the ease of opening and closing operation and improving work efficiency.

[0043] Reference Figure 1 and Figure 2 A fixing plate 13 is threadedly connected to the middle of the outer wall of the threaded rod 7. The fixing plate 13 is designed to prevent the bolt 8 from being tightly fitted with the cover plate 9. A connecting plate 14 is fixedly connected to the bottom of the base 1. Threaded holes 15 are opened at the four corners of the top of the connecting plate 14 for fixing to the wall. Screws 16 are threadedly connected inside the multiple threaded holes 15. Caps 17 are fixedly connected to the top of the multiple screws 16 for connecting the connecting plate 14 and the wall.

[0044] Specifically, the fixing plate 13 in the middle of the outer wall of the threaded rod 7 has a smooth design, which can prevent the bolt 8 from being too tightly fitted to the cover plate 9. The connecting plate 14 at the bottom of the base 1 and the four corners at the top have threaded holes 15, which can be used to fix the entire wire clamp to the wall with screws 16. The cap 17 on the top of the screw 16 not only makes the connection more secure, but also prevents the screw 16 from loosening or being corroded to a certain extent, ensuring the stability of the wire clamp after installation and allowing it to work reliably on the wall.

[0045] Reference Figure 1 , Figure 2 and Figure 3A fixing plate 18 is fixedly connected to the rear side of the top cover 5, and a warning sign 19 is fixedly connected to the rear side of the fixing plate 18 for reminder. A lamp holder 20 is fixedly connected to the top rear side of the top seat 4, and an alarm light 21 is fixedly connected to the rear side of the lamp holder 20. An alarm is triggered when the main line is without power. A handle 22 is fixedly connected to the top rear side of the top seat 4 for easy pulling. Multiple anti-slip posts 23 are fixedly connected to the front side of multiple pressure plates 12 for clamping the main line.

[0046] Specifically, the fixing plate 18 on the rear side of the top cover 5 is connected to the warning sign 19, which serves as a warning. The alarm light 21 on the lamp holder 20 on the rear top of the top seat 4 can sound an alarm when the main line is out of power. The handle 22 on the rear top of the top seat 4 makes it easy to pull the top seat 4 for convenient operation. The multiple anti-slip posts 23 on the front side of the multiple pressure plates 12 can enhance the clamping effect on the main line, prevent the main line from sliding, and ensure the stability of the main line connection.

[0047] Working principle: Two hinges 3 on the top rear side of the base 1 connect to the top seat 4. This connection allows the top seat 4 to open and close easily. On the bottom inner side of the base 1, the fixing block 6 is threadedly connected to the threaded rod 7. Rotating the bolt 8 in the middle of the threaded rod 7 allows the cover plate 9, which is threadedly connected to the threaded rod 7, to move up and down. The wire feeding plates 10 on the left and right sides of the base 1 provide a position for placing the main wire. When a larger main wire is placed on the wire feeding plate 10, the spring 11 uses its own elastic potential energy to push the pressure plate 12, applying appropriate squeezing force according to the thickness of the main wire to ensure the stability of the main wire. Thus, the connector can effectively adapt to main wires of different sizes, providing them with good support and stable connection.

[0048] Furthermore, the buckle 201 is fixed on both sides of the top seat 4, and the card box 202 is located on both sides of the base 1. When the top seat 4 and the base 1 need to be closed and fixed, the buckle 201 is inserted into the card box 202. The pressing block 206 in the groove 205 on the front and rear sides of the card box 202 applies a certain pressure to the buckle 201 during the locking process. When the top seat 4 needs to be opened, the elastic potential energy of the second spring 203 is released, pushing the support plate 204, so that the buckle 201 pops out from the card box 202, realizing the convenient opening of the top seat 4.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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.
