Description

Technical Field

[0001] This utility model relates to the field of testing instrument technology, and in particular to a testing instrument for power testing. Background Technology

[0002] Power testing instruments are devices used to measure and monitor various parameters in power systems, including voltage, current, power, frequency, harmonics, etc. They are widely used in the operation and maintenance, fault diagnosis, and performance evaluation of power systems.

[0003] The announcement number CN212872714U discloses a power testing instrument. When workers need to use the equipment during aerial work, they can pull up the ring to increase the distance between the fixed hook and the limit hook, thereby locking the arm or cable. Then, by releasing the ring, spring A controls the push rod to squeeze the push rod, which in turn controls the limit hook and the fixed hook to clamp the arm or cable, thus facilitating the safety of workers during aerial work and effectively preventing the equipment from falling from a height.

[0004] When this electrical testing instrument is fixed to an object, it is secured by a spring. However, due to the elasticity of the spring, it is prone to loosening when subjected to external impact, causing the equipment to fall from a height and posing a safety hazard. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a power testing instrument.

[0006] The present invention is achieved by the following technical solution: a power testing instrument, including a testing instrument body, an extension plate fixedly connected to the right end of the testing instrument body, a fixing hook fixedly connected to the top and bottom of the extension plate, a locking component provided at the bottom of the extension plate, and a fixing component provided at the right end of the testing instrument body.

[0007] The locking assembly includes a fixing block, a fixing rod rotatably connected to the inner wall of the fixing block, a movable hook fixedly connected to the surface of the fixing rod, a protective box fixedly connected to the front end of the fixing block, a ratchet fixedly connected to the surface of the fixing rod, a pawl rotatably connected to the inner wall of the protective box, a pull rod hinged to one end of the pawl, a return spring sleeved on the surface of the pull rod, and a limit ring fixedly connected to the surface of the pull rod.

[0008] The above technical solution involves rotating the fixed rod, which in turn rotates the movable hook to fix the detector body onto the object. When the fixed rod rotates, the ratchet rotates, which, together with the pawl, achieves one-way locking, preventing the device from falling off after fixing and ensuring safety during use. The detector body is the same as the device in the announcement number CN212872714U, which is existing technology and has been disclosed, so it will not be described in detail.

[0009] As a further improvement to the above solution, the top of the fixing block is fixedly connected to the bottom of the extension plate, and the surface of the fixing rod is rotatably connected to the inner wall of the protective box.

[0010] The above technical solution uses a protective box to shield the ratchet and pawl, preventing accidental loosening.

[0011] As a further improvement to the above solution, the ratchet is located inside the protective box, the top of the pull rod extends to the outside of the protective box, and the surface of the pull rod is slidably connected to the inner wall of the protective box.

[0012] With the above technical solution, since the top of the pull rod is hinged to the pawl, the pawl can rotate normally without affecting the position of the pull rod.

[0013] As a further improvement to the above solution, the top of the return spring is fixedly connected to the top of the inner wall of the protective box, and the bottom of the return spring contacts the top of the limiting ring.

[0014] With the above technical solution, when the pawl rotates, it pushes the pull rod to slide upward, causing the limit ring to squeeze the return spring. The return spring provides the return force, so that the pawl automatically returns to its original position after being released.

[0015] As a further improvement to the above solution, the fixing component includes a handle, a positioning hole is provided on the left inner wall of the handle, a fixing ring is fixedly connected to the inner wall of the positioning hole, a positioning plate is provided inside the positioning hole, a slide rod is fixedly connected to the right end of the positioning plate, and a mounting groove is provided on the right inner wall of the handle, a spring is provided inside the mounting groove.

[0016] The above technical solution uses a sliding rod to move the fixing ring, causing the positioning plate to detach from the positioning hole. Simultaneously, the protruding part of the sliding rod compresses the spring, securing the handle to the belt. Releasing the sliding rod allows the spring to elastically return and push the sliding rod to move, allowing the positioning plate to enter the positioning hole. Rotating the sliding rod then causes the positioning plate to rotate within the positioning hole, misaligning the protruding part of the positioning plate with the through groove of the fixing ring. This prevents the positioning plate from detaching from the positioning hole, avoiding it from falling during transport and ensuring stability during carrying.

[0017] As a further improvement to the above solution, the left end of the handle is fixedly connected to the right end of the detector body, and a through groove is provided on the inner wall of the fixing ring.

[0018] With the above technical solution, the through groove on the inner wall of the fixing ring is larger than the diameter of the positioning plate, so that the positioning plate can enter the interior of the positioning hole. The positioning plate is circular with protruding sides. The fixing ring limits the positioning plate and effectively prevents it from falling off.

[0019] As a further improvement to the above solution, the right end of the slide rod passes through the handle and extends outward.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] This utility model features a locking assembly. Specifically, rotating the fixing rod causes the movable hook to rotate, which in turn fixes the detector body to the object. When the fixing rod rotates, the ratchet rotates, which, together with the pawl, achieves one-way locking, preventing the device from falling off after being fixed and ensuring safety during use.

[0022] This invention utilizes a fixing component. Specifically, a sliding rod moves a fixing ring, causing the positioning plate to detach from the positioning hole. Simultaneously, the protruding part of the sliding rod compresses a spring, securing the handle to the belt. Releasing the sliding rod allows the spring to elastically return and push the sliding rod to move again, allowing the positioning plate to re-enter the positioning hole. Rotating the sliding rod then causes the positioning plate to rotate within the positioning hole, misaligning the protruding part of the positioning plate with the through groove of the fixing ring. This prevents the positioning plate from detaching from the positioning hole, avoiding it from falling during transport and ensuring stability during carrying. Attached Figure Description

Detailed Implementation

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0032] Example:

[0033] Please combine Figure 1-5 An electrical testing instrument according to this embodiment includes a testing instrument body 1, an extension plate 2 fixedly connected to the right end of the testing instrument body 1, a fixing hook 3 fixedly connected to the top and bottom of the extension plate 2, a locking component 4 provided at the bottom of the extension plate 2, and a fixing component 5 provided at the right end of the testing instrument body 1.

[0034] The locking assembly 4 includes a fixing block 401, a fixing rod 402 rotatably connected to the inner wall of the fixing block 401, a movable hook 403 fixedly connected to the surface of the fixing rod 402, a protective box 404 fixedly connected to the front end of the fixing block 401, a ratchet 405 fixedly connected to the surface of the fixing rod 402, a pawl 406 rotatably connected to the inner wall of the protective box 404, a pull rod 407 hinged to one end of the pawl 406, a return spring 408 sleeved on the surface of the pull rod 407, and a limit ring 409 fixedly connected to the surface of the pull rod 407. When working at height, rotating the fixing rod 402 causes the movable hook 403 to rotate, which, together with the fixing hook 3, fixes the detector body 1 to the object. When the fixing rod 402 rotates, the ratchet 405 rotates, which, together with the pawl 406, achieves one-way locking, preventing the device from falling after fixing and ensuring safety during use.

[0035] The top of the fixing block 401 is fixedly connected to the bottom of the extension plate 2, and the surface of the fixing rod 402 is rotatably connected to the inner wall of the protective box 404.

[0036] The ratchet 405 is located inside the protective box 404, and the top of the pull rod 407 extends to the outside of the protective box 404. The surface of the pull rod 407 is slidably connected to the inner wall of the protective box 404. When it needs to be removed from the object, pull the pull rod 407 to make the pawl 406 rotate upward. At the same time, the limiting ring 409 pushes the return spring 408 to squeeze. At this time, the ratchet 405 is not limited by the pawl 406, so the fixed rod 402 can rotate in the opposite direction, which drives the movable hook 403 to rotate and disengage from the object. The operation is simple and convenient.

[0037] The top of the return spring 408 is fixedly connected to the top of the inner wall of the protective box 404, and the bottom of the return spring 408 is in contact with the top of the limit ring 409.

[0038] The fixing component 5 includes a handle 501. A positioning hole 502 is formed on the left inner wall of the handle 501. A fixing ring 503 is fixedly connected to the inner wall of the positioning hole 502. A positioning plate 504 is disposed inside the positioning hole 502. A slide rod 505 is fixedly connected to the right end of the positioning plate 504. A mounting groove 506 is formed on the right inner wall of the handle 501. A spring 507 is disposed inside the mounting groove 506. The slide rod 505 drives the fixing ring 503 to move, causing the positioning plate 504 to disengage from the positioning hole 502. Simultaneously, the protrusion of the slide rod 505... The spring 507 is compressed, locking the handle 501 onto the belt. Then, the slide bar 505 is released, and the spring 507 elastically returns to its original position, pushing the slide bar 505 to move. This allows the positioning plate 504 to enter the positioning hole 502. Then, the slide bar 505 is rotated, causing the positioning plate 504 to rotate on the inner wall of the positioning hole 502. This causes the protruding part of the positioning plate 504 to be misaligned with the through groove of the fixing ring 503, thus preventing the positioning plate 504 from detaching from the positioning hole 502 and avoiding it from falling during carrying, ensuring stability during carrying.

[0039] The left end of the handle 501 is fixedly connected to the right end of the detector body 1, and a through groove is provided on the inner wall of the fixing ring 503.

[0040] The right end of the slide bar 505 passes through the handle 501 and extends outward.

[0041] The implementation principle of a power testing instrument in this embodiment is as follows: When the instrument body 1 needs to be secured to the belt, the sliding rod 505 drives the fixing ring 503 to move, causing the positioning plate 504 to disengage from the positioning hole 502. Simultaneously, the protruding part of the sliding rod 505 presses against the spring 507, securing the handle 501 to the belt. Then, the sliding rod 505 is released, and the spring 507 elastically returns to its original position, pushing the sliding rod 505 to move, allowing the positioning plate 504 to enter the positioning hole 502. Then, the sliding rod 505 is rotated, causing the positioning plate 504 to rotate within the inner wall of the positioning hole 502, causing the protruding part of the positioning plate 504 to misalign with the through groove of the fixing ring 503, thereby preventing the positioning plate 504 from disengaging from the positioning hole 502. To prevent the device from falling during transport and ensure its stability, when working at heights, rotating the fixing rod 402 causes the movable hook 403 to rotate, which, together with the fixing hook 3, secures the detector body 1 to the object. When the fixing rod 402 rotates, the ratchet 405 rotates, which, together with the pawl 406, achieves one-way locking, preventing the device from falling after being secured and ensuring safety during use. When it is necessary to remove the device from the object, pulling the lever 407 causes the pawl 406 to rotate upward. At the same time, the limiting ring 409 pushes the return spring 408 to compress it. At this time, the ratchet 405 is no longer limited by the pawl 406, allowing the fixing rod 402 to rotate in the opposite direction, causing the movable hook 403 to rotate and disengage from the object. The operation is simple and convenient.

[0042] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
