Description

Technical Field

[0001] This invention relates to the field of clamp-on ammeter technology, specifically to an intelligent clamp-on ammeter. Background Technology

[0002] A smart clamp meter is a portable power testing instrument that can measure AC current without interrupting the circuit. These devices typically feature high accuracy and stability, and integrate multiple measurement functions such as voltage, power, and frequency. The design of smart clamp meters usually prioritizes user safety, employing non-contact measurement technology to reduce operational risks. However, when testing current at high locations or at the neutral point of a transformer using a clamp meter, improper operation can easily cause the meter to slip from the operator's hand and collide with the ground, damaging internal components and affecting the efficiency and safety of the measurement process.

[0003] According to the description of a smart clamp ammeter published on the patent website (authorization announcement number: CN212872631U), the smart clamp ammeter includes a "current plate body, a concave frame, a slider" etc., to perform measurement work.

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] This intelligent clamp-on ammeter uses a current plate body, concave frame, slider, etc. to perform measurement work. When it is necessary to test the current at a high position or at the neutral point of a transformer using this clamp-on ammeter, not only do operators need to climb using external equipment, but the clamp-on ammeter is also prone to falling from the operator's hand and colliding with the ground due to improper operation, which can damage the internal components of the clamp-on ammeter and affect the efficiency and safety of the measurement work. Therefore, this ammeter needs to be improved. Summary of the Invention

The locking block is inserted into the limiting groove, so that the connecting shaft is in a stable state in the fixed sleeve under the action of the locking block.

[0019] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0020] 1. This intelligent clamp-on ammeter, through its fixed components, allows for easy measurement of cables at heights. Simply fix the ammeter to the base, fixed frame, and concave frame, and connect the connecting shaft to the fixed sleeve. The support rod then lifts the ammeter, enabling it to measure the current of the cable. Workers do not need to climb to heights using external equipment, reducing the risks of working at heights and preventing falls. It also allows for rapid current measurement, saving climbing and movement time, improving work efficiency, and providing convenient operation. The installation and removal of the fixed components are also highly efficient. When measuring cables at heights, first... The ammeter body slides into the fixed frame. During this sliding process, the clamp-on ammeter body presses against the concave frame, causing the concave frame to press against the first connecting rod and the first inclined block. This causes the first spring to deform, and the first inclined block to press against the second inclined block and the second connecting rod, causing the second spring to deform as well. When the clamp-on ammeter body is fully slid into the fixed frame and the outer periphery of the clamp-on ammeter body contacts the inner side of the concave frame and the base, the pressing action of the first inclined block against the second inclined block will cause the second inclined block to be positioned to the right of the first inclined block. This allows the second inclined block to limit the movement of the first inclined block, stabilizing the clamp-on ammeter body within the fixed frame. Simultaneously, the connecting shaft is inserted into the fixed sleeve, stabilizing the support rod and the fixed frame. This allows the clamp-on ammeter body to be lifted under the action of the support rod for measurement.

[0021] 2. This intelligent clamp-on ammeter, through its designed pressing component, allows for lifting of the clamp-on ammeter body when it is needed to measure the current of cables located at a high position. During this lifting process, when current measurement is required, the lever, pressing plate, third spring, and second pull ring press the wrench, causing the clamp head to rotate and fit over the cable. This prevents the clamp-on ammeter from being unable to press the wrench and thus avoids the clamp head being trapped outside the cable due to the ammeter body being at a high position. The phenomenon of encirclement can be improved by pressing, which not only enhances the usage effect but also increases the measurement efficiency. The operation is convenient. When it is necessary to put the clamp head around the cable, pull down the second pull ring. The second pull ring drives the pull rod, disc, and pressing plate to move downward within the support frame. The disc drives the third spring to deform, which presses the wrench under the action of the pressing plate. The wrench drives the clamp head to rotate. When the clamp head is around the cable, release the second pull ring. The third spring returns to its original position, which drives the disc to move the pull rod and pressing plate upward. This releases the pressing plate from pressing the wrench, and the measurement work can then be carried out.

[0022] 3. This intelligent clamp-on ammeter, through its handheld mechanism, allows for handheld current measurement. The operator simply needs to wear insulated gloves and insert the middle three fingers into the handheld holder. The fixing rod, connecting plate, clamp, and fifth spring secure the operator's hand. This secures the operator's hand, preventing fatigue from prolonged handheld measurement and preventing the meter from slipping, ensuring safety and stability during measurement. Furthermore, the clamp and fifth spring allow for forward and backward movement to accommodate different operator hand positions, improving accuracy and efficiency. The fixed effect, combined with the action of the limiting rod, the third pull ring, and the fourth spring, facilitates the installation and disassembly of the handheld frame, improving the usability and meeting different usage scenarios and needs. Simultaneously, the connecting block causes the handheld frame to rotate around the outer edge of the round rod, making it horizontal. The limiting rod and the fourth spring then fix the rotated connecting block, ensuring the handheld frame is stable. This handheld frame supports the clamp-on ammeter body, helping to maintain stability, especially during measurements where readings are required. Stable placement reduces reading errors and makes operation of the clamp-on ammeter more convenient, particularly for long-term or repeated measurements, reducing operator fatigue.

[0023] 4. This intelligent clamp-on ammeter, through its limiting mechanism, allows for cable measurement of cables at elevated locations. The connecting shaft is inserted into the fixed sleeve, and with the support rod in place, the clamp-on ammeter can measure the current of the cable at the elevated position. When the connecting shaft is inserted into the fixed sleeve, the locking block, compression ring, telescopic rod, and sixth spring limit the connection shaft, ensuring its stability within the fixed sleeve. This allows the clamp-on ammeter to be raised for measurement under the support rod. This design facilitates the installation and disassembly of the connecting shaft, improving ease of use and efficiency. When the connecting shaft needs to be inserted into the fixed sleeve, simply pull the rectangular plate to the left. This causes the rectangular plate to move the compression ring and the locking block to the left, compressing the telescopic rod and the sixth spring. At this point, the connecting shaft can be inserted into the fixed sleeve, aligning it with the limiting groove of the fixed sleeve. Once insertion is complete, release the rectangular plate, and the sixth spring will return to its original position. This allows the telescopic rod to move the compression ring and the locking block to the right, inserting the locking block into the limiting groove. This ensures that the connecting shaft, the fixed block, and the support rod are in a stable state. Attached Figure Description

[0053] Example 4

[0054] See Figure 1-12Based on Examples 1, 2, and 3, the limiting mechanism 5 further includes a support frame 51, which is fixedly connected to the bottom of the mounting plate 3198. A limiting cylinder 52 is fixedly connected to the inner side of the support frame 51. A telescopic rod 54 is fixedly connected inside the limiting cylinder 52. A compression ring 56 is fixedly connected to the right side of the telescopic rod 54. The compression ring 56 is slidably connected inside the limiting cylinder 52. A sixth spring 55 is sleeved around the telescopic rod 54. The left side of the sixth spring 55 is fixedly connected inside the limiting cylinder 52. The right side of the sixth spring 55 is fixedly connected to the left side of the compression ring 56. A locking block 53 is fixedly connected to the right side of the compression ring 56. The locking block 53 is inserted into the connecting shaft 316. A rectangular plate 57 is fixedly connected to the outer side of the compression ring 56. The rectangular plate 57 is slidably connected inside the limiting cylinder 52.

[0055] Furthermore, the locking block 53 extends through the fixed sleeve 315. Limiting grooves are respectively opened inside the fixed sleeve 315 and the connecting shaft 316, and the two limiting grooves correspond to each other. The locking block 53 is inserted into the limiting groove, so that the connecting shaft 316 is in a stable state inside the fixed sleeve 315 under the action of the locking block 53.

[0056] In actual operation, when this device is used to measure cables at high locations, the clamp-on ammeter body 1 is first slid into the fixed frame 312. During this sliding process, the clamp-on ammeter body 1 presses against the concave frame 3193, causing the concave frame 3193 to press against the first connecting rod 318 and the first inclined block 319, and causing the first spring 3192 to deform. The first inclined block 319 presses against the second inclined block 3191 and the second connecting rod 3194, and causes the second spring 3195 to deform. When the clamp-on ammeter body 1 is fully slid into the fixed frame 312, and the outer periphery of the clamp-on ammeter body 1 is in contact with the inner side of the concave frame 3193 and the base 311, the first inclined block 319... During the compression process, the second inclined block 3191 will be positioned to the right of the first inclined block 319. This allows the second inclined block 3191 to limit the first inclined block 319, stabilizing the clamp-on ammeter body 1 within the fixed frame 312. Simultaneously, the rectangular plate 57 is pulled to the left, causing the compression ring 56 and the locking block 53 to move to the left, compressing the telescopic rod 54 and the sixth spring 55. At this point, the connecting shaft 316 can be inserted into the fixed sleeve 315, aligning it with the limiting groove of the fixed sleeve 315. Once insertion is complete, the rectangular plate 57 is released, the sixth spring 55 returns to its original position, and the telescopic rod 54 moves the compression ring 56 and the locking block 53 to the right, thus stabilizing the clamp-on ammeter body 1. When block 53 is inserted into the limiting groove, the connecting shaft 316, fixing block 317, and support rod 313 are stabilized. Simultaneously, when the connecting shaft 316 is inserted into the fixing sleeve 315, the support rod 313 and fixing frame 312 are stabilized. Under the action of the support rod 313, the clamp-on ammeter body 1 can be lifted. During the lifting process, when the clamp head 2 needs to be placed around the cable, the second pull ring 326 is pulled downwards. This causes the second pull ring 326 to move the pull rod 322, disc 325, and pressing plate 323 downwards within the support frame 321. The disc 325 also causes the third spring 324 to deform, thus pressing the wrench 6 under the action of the pressing plate 323. This causes the wrench 6 to rotate the clamp head 2. When the clamp head 2 is placed around the cable, the second pull ring 326 is released, the third spring 324 returns to its original position, causing the disc 325 to move the pull rod 322 and the pressing plate 323 upwards. This releases the pressing plate 323 from pressing the wrench 6, allowing measurement to be performed through the clamp ammeter body 1. When it is necessary to use the clamp ammeter body 1 to measure nearby cables, firstly, under the action of the rectangular plate 57, the squeezing ring 56, and the locking block 53, the connecting shaft 316 is removed from the fixed sleeve 315, allowing the support rod 313 to be removed. At the same time, the clamp ammeter body 1 is pulled out from the fixed frame 312, and the first pull ring 3196 is pulled backwards, causing the first pull ring 3196 to move the second connecting rod 3194 and the second inclined block 3191.This releases the second inclined block 3191 from the first inclined block 319, resets the first spring 3192, and puts the concave frame 3193 in the reset state, facilitating the next fixing operation. Simultaneously, pulling the third pull ring 44 upwards moves the limiting rod 491 and causes the fourth spring 43 to deform, sliding the connecting block 42 onto the periphery of the round rod 41. This ensures the slots of the round rod 41 and connecting block 42 correspond. Once the sliding is complete, releasing the third pull ring 44 resets the fourth spring 43, allowing the limiting rod 491 to insert into the slot. This stabilizes the connecting block 42 and the handheld frame 45. The operator only needs to wear insulated gloves and insert the middle three fingers of their hand into the handheld frame 45 to adjust the clamping plate 46, fixing rod 48, and fifth spring 47. By applying pressure, the clamp plate 46 stabilizes the operator's hand, allowing the clamp-on ammeter 1 to be placed around the hand for measurement. This prevents fatigue from prolonged hand-holding and avoids the meter falling. When the clamp-on ammeter 1 needs to be placed for measurement, the connecting block 42 rotates the handheld frame 45 around the round rod 41, making it horizontal. The limiting rod 491 and the fourth spring 43 then fix the rotated connecting block 42, stabilizing the handheld frame 45 and supporting the clamp-on ammeter 1. This support helps maintain the clamp-on ammeter's stability.
