Description

Technical Field

[0001] This utility model relates to the field of ammeter technology, specifically to an ammeter that is easy to install. Background Technology

[0002] An ammeter is an instrument specifically designed to measure the strength of current in a circuit. It displays the readings visually through pointer deflection or digital readings, allowing operators to monitor the circuit's operating status in real time. In practical applications, especially in modern industrial power distribution cabinets or control cabinets, digital ammeters have gradually replaced traditional pointer-type instruments due to their advantages of accurate readings, high integration, and the ability to be equipped with alarm or communication functions.

[0003] In existing technologies, digital ammeters mostly use embedded snap-fit ​​installation. That is, after the cabinet door is opened, the meter body is embedded, and then the metal snaps on both sides of the meter are pushed on the back side of the cabinet door, so that the barbs at the end of the snaps hook onto the inside of the door panel. The meter body is fixed by the clamping force generated by the elastic deformation of the metal sheet. However, the locking force of the snaps depends on the elasticity of the metal. After long-term use, metal fatigue can easily lead to a decrease in elasticity. In a vibrating environment, the snaps may loosen or fall off. When disassembly is required, the snaps need to be pried with a screwdriver on the back side of the cabinet door. The operating space is small and it is impossible to see the state of the snaps being dislodged. It is easy to break the snaps. After the snaps are damaged, the entire ammeter usually needs to be replaced, resulting in high maintenance costs. Utility Model Content

[0004] The purpose of this invention is to provide an ammeter that is easy to install, solving the problems of easy weakening of locking force and inconvenient disassembly and assembly operations in the existing snap-on installation structure.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to an ammeter that is easy to install. It includes an ammeter body, an mounting frame fitted around the outer side of the ammeter body, and a connecting rod on one side of the mounting frame. One end of each connecting rod penetrates the ammeter body and extends outwards. The number of connecting rods is fixed at four. A fixing component is provided between each pair of adjacent connecting rods. The fixing component includes a connecting plate, a placement groove on the outer side of the connecting plate, mounting holes at both ends of the placement groove, two sliding grooves on the inner surface of the placement groove, and a moving block slidably connected inside the sliding groove. A fixing block is provided at one end of the moving block, and a spring is fixedly installed at the other end of the moving block. The other end of the spring is fixedly installed with a mounting block, which is fixedly installed on the inner wall of the sliding groove. The connecting rod is fitted inside the mounting hole, and a fixing hole is provided on the outer side of the connecting rod. One end of the fixing block penetrates the sliding groove and is fitted inside the fixing hole.

[0006] Furthermore, a cover plate is fixedly installed inside the placement groove, and an opening is provided on the outer side of the cover plate. A lever is fixedly installed on the outer side of the movable block, and one end of the lever is slidably connected to the inside of the opening.

[0007] Furthermore, one end of the lever is provided with a baffle, which is located inside the passage and covers the outside of the slide groove. A limiting plate is also installed inside the passage. A limiting groove is opened at one end of the baffle, and a protrusion is provided on the outside of the limiting plate. The protrusion is fitted and installed inside the limiting groove.

[0008] Furthermore, a first groove is provided at the bottom of the placement slot, a first magnetic block is installed inside the first groove, a second groove is provided at one end of the limiting plate, a pull block is provided at the other end of the limiting plate, a second magnetic block is installed inside the second groove, and the first magnetic block and the second magnetic block are magnetically connected.

[0009] Furthermore, one end of the connecting rod is provided with a tapered surface, and one end of the fixing block is provided with a guide slope.

[0010] Furthermore, both the toggle block and the pull block have anti-slip stripes on their outer sides.

[0011] This utility model has the following beneficial effects: (1) This utility model positions the ammeter body by fitting it into the mounting frame and then locking it by installing the fixing component from the front. The entire installation process is completed on the front of the cabinet door. The locking force is continuously provided by the spring, and there is no problem of clamping force attenuation caused by metal fatigue. In a vibration environment, the fixing block and the fixing hole can always be engaged. When disassembling, you only need to move the lever on the front to unlock and remove the fixing component. There is no need to enter the back of the cabinet door to pry the buckle with a screwdriver, which avoids the risk of limited operating space and buckle breakage. Even if the fixing component is worn and fails, you only need to replace the fixing component. There is no need to scrap the entire ammeter body, and the maintenance cost is low.

[0012] (2) Through the cooperation between the limiting plate and the toggle block, the limiting plate physically blocks the toggle block after the fixed component is locked. Combined with the magnetic block's adsorption and positioning, it achieves the anti-loosening effect. In environments with continuous vibration, such as power distribution cabinets, even if the spring thrust fluctuates slightly due to long-term use, or the vibration inertial force attempts to push the toggle block to move, the limiting plate can restrict the displacement path of the toggle block, preventing the possibility of the fixed block accidentally coming out of the fixed hole, and further improving the reliability and safety of locking.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0016] 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.

[0017] Please see Figures 1-5As shown, this utility model is a conveniently installed ammeter, including an ammeter body 1, an installation frame 2 fitted on the outer side of the ammeter body 1, a connecting rod 201 on one side of the installation frame 2, one end of the connecting rod 201 penetrating the ammeter body 1 and extending outward, the number of connecting rods 201 is fixed to four, and a fixing component 3 is provided between each two adjacent connecting rods 201, the fixing component 3 including a connecting plate 301, the outer side of the connecting plate 301 has a placement groove, both ends of the placement groove have installation holes 307, and the inner surface of the placement groove... Two sliding grooves 302 are provided. A movable block 303 is slidably connected inside the sliding groove 302. A fixed block 304 is provided at one end of the movable block 303. A spring 305 is fixedly installed at the other end of the movable block 303. An installation block 306 is fixedly installed at the other end of the spring 305. The installation block 306 is fixedly installed on the inner wall of the sliding groove 302. A connecting rod 201 is fitted inside the installation hole 307. A fixed hole 202 is provided on the outer side of the connecting rod 201. One end of the fixed block 304 passes through the sliding groove 302 and is fitted inside the fixed hole 202. The mounting frame 2 is fixedly installed on the back of the cabinet door by bolts, and one end of the connecting rod 201 passes through the cabinet door and extends outward. A cover plate 308 is fixedly installed inside the placement slot. An opening is provided on the outside of the cover plate 308. A lever 309 is fixedly installed on the outside of the moving block 303. One end of the lever 309 is slidably connected to the inside of the opening. One end of the connecting rod 201 is provided with a tapered surface, and one end of the fixing block 304 is provided with a guide slope. Specifically, first, the ammeter body 1 is inserted from the front of the cabinet door into the mounting frame 2, which is pre-fixed to the back of the cabinet door. The four connecting rods 201 pass through the corresponding through holes in the ammeter body 1. The ammeter body 1 slides along the connecting rods 201 until it is flush with the cabinet door surface. Then, the fixing assembly 3 is removed, and the mounting holes 307 at both ends of the connecting plate 301 are aligned with the protruding ends of two adjacent connecting rods 201. The connecting plate 301 is then pushed towards the cabinet door, allowing the connecting rods 201 to pass through the mounting holes 307. During this process, the tapered surface at the end of the connecting rod 201 first contacts the guide slope at the end of the fixing block 304. As the tapered surface slides along the guide slope, it generates a lateral force, pushing the fixing block 304. 4. Move the moving block 303 backward along the slide groove 302 in a direction away from the mounting hole 307. At the same time, the moving block 303 compresses the spring 305. As the connecting plate 301 continues to be pushed in, the fixing block 304 slides tightly against the outer wall of the connecting rod 201 under the action of the spring 305 until the connecting plate 301 is fully in place. The fixing block 304 is aligned with the fixing hole 202 on the connecting rod 201. At this time, the spring 305 releases the thrust, driving the moving block 303 to drive the fixing block 304 through the side wall of the slide groove 302 and insert it into the fixing hole 202. The fixing component 3 is then locked on the connecting rod 201. The ammeter body 1 is pressed and fixed between the cabinet door and the mounting frame 2 by the connecting plate 301. During disassembly, use your finger to move the lever 309 at the opening of the cover plate 308 on the front of the cabinet door. The lever 309 will cause the moving block 303 to slide along the slide groove 302 away from the mounting hole 307. The moving block 303 will compress the spring 305 and cause the fixing block 304 to completely exit from the fixing hole 202 of the connecting rod 201. Then, pull the connecting plate 301 outward along the connecting rod 201 and remove the fixing component 3. After all the fixing components 3 are removed, the ammeter body 1 can be pulled forward from the mounting frame 2 to complete the disassembly. One end of the lever 309 is provided with a baffle 310, which is located inside the passage and covers the outside of the slide groove 302. A limiting plate 4 is also installed inside the passage. A limiting groove 311 is opened at one end of the baffle 310. A protrusion 401 is provided on the outside of the limiting plate 4, and the protrusion 401 is installed in the limiting groove 311. The bottom of the placement slot has a first groove, and a first magnetic block 5 is installed inside the first groove. A second groove is provided at one end of the limiting plate 4, and a pull block 402 is provided at the other end of the limiting plate 4. A second magnetic block 6 is installed inside the second groove, and the first magnetic block 5 and the second magnetic block 6 are magnetically connected.

[0018] In this process, after the fixing component 3 is installed and the fixing block 304 is inserted into the fixing hole 202 of the connecting rod 201, the operator holds the pull block 402 at the end of the limiting plate 4 and inserts the limiting plate 4 along the opening on the cover plate 308. During the insertion of the limiting plate 4, the outer protrusion 401 slides along the limiting groove 311 on the end face of the baffle 310, which serves as a guide. When the limiting plate 4 is pushed to the limit position, the second groove at the bottom of the limiting plate 4 is aligned with the first groove at the bottom of the placement groove, and the first magnetic block 5 and the second magnetic block 6 attract each other, thus limiting the position. Plate 4 is fixed inside the opening. At this time, the body of the limiting plate 4 covers the outside of the lever 309, blocking the baffle 310 and the lever 309, preventing the lever 309 from sliding in the unlocking direction. When it is necessary to disassemble the ammeter body 1, the operator holds the pull block 402 and pulls the limiting plate 4 outward to overcome the magnetic attraction between the first magnetic block 5 and the second magnetic block 6, and completely pulls the limiting plate 4 out of the opening. After the limiting plate 4 is removed, the movement path of the lever 309 and the baffle 310 is released, and the operator can then move the lever 309 to perform the unlocking operation. Both the toggle block 309 and the pull block 402 have anti-slip stripes on their outer sides.

[0019] In use, first, slide the ammeter body 1 onto the mounting frame 2, which is pre-fixed to the back of the cabinet door, from the front of the cabinet door. Then, pass the four connecting rods 201 through the corresponding through holes of the ammeter body 1. The ammeter body 1 slides along the connecting rods 201 until it is in contact with the surface of the cabinet door. Then, take out the fixing component 3, align the mounting holes 307 at both ends of the connecting plate 301 with the protruding ends of the two adjacent connecting rods 201, and push the connecting plate 301 toward the cabinet door so that the connecting rods 201 pass through the mounting holes 307. During this process, the tapered surface at the end of the connecting rod 201 first contacts the guide slope at the end of the fixing block 304. When the tapered surface slides along the guide slope, it generates a lateral force, which pushes the fixing block 304 and drives the moving block 303 to move backward along the slide groove 302 away from the mounting hole 307. At the same time, the moving block 303 compresses the spring 305. As the connecting plate 301 continues to be pushed in, the fixing block 304 slides tightly against the outer wall of the connecting rod 201 under the pushing force of the spring 305 until the connecting plate 301 is fully in place. At this time, the fixing block 304 is aligned with the fixing hole 202 on the connecting rod 201. At this time, the spring 305 releases its pushing force, driving the moving block 303 to move the fixing block 304 through the side wall of the slide groove 302 and insert it into the fixing hole 202. The fixing component 3 is then locked onto the connecting rod 201, and the ammeter body 1 is pressed and fixed by the connecting plate 301. After the fixing component 3 is installed between the cabinet door and the mounting frame 2, the operator holds the pull block 402 at the end of the limiting plate 4 and inserts the limiting plate 4 along the opening on the cover plate 308. During the insertion of the limiting plate 4, the outer protrusion 401 slides along the limiting groove 311 on the end face of the baffle 310, which serves as a guide. When the limiting plate 4 is pushed to the limit position, the second groove at the bottom of the limiting plate 4 is aligned with the first groove at the bottom of the placement groove, and the first magnetic block 5 and the second magnetic block 6 attract each other, fixing the limiting plate 4 in place. Inside the passage, the limiting plate 4 covers the outside of the lever 309, blocking the baffle 310 and the lever 309, preventing the lever 309 from sliding in the unlocking direction. When disassembly is required, the operator holds the pull block 402 and pulls the limiting plate 4 outwards, overcoming the magnetic attraction between the first magnetic block 5 and the second magnetic block 6, to completely remove the limiting plate 4 from the passage. After the limiting plate 4 is removed, the movement path of the lever 309 and the baffle 310 is released, allowing the operator to move the lever 309 to perform the unlocking operation. Using your finger, move the lever 309 at the opening of the cover plate 308 on the front of the cabinet door. This will cause the lever 309 to move the moving block 303 along the slide groove 302 away from the mounting hole 307. The moving block 303 will compress the spring 305 and cause the fixing block 304 to completely exit from the fixing hole 202 of the connecting rod 201. Then, pull the connecting plate 301 outward along the connecting rod 201 and remove the fixing component 3. After all the fixing components 3 are removed, the ammeter body 1 can be pulled forward from the mounting frame 2 to complete the disassembly.
