Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a fault detector for air conditioner maintenance. Background Art

[0002] In modern life, air conditioners have become an indispensable electrical appliance for people and are widely used in various fields such as homes, offices, and commercial spaces. As the number of air conditioners used continues to rise and the number of years of use increases, their failure rate also increases accordingly, which puts higher demands on air conditioner maintenance work. Fault detection is the primary link in maintenance, and its technical effectiveness and convenience are crucial.

[0003] Traditional testing methods often require maintenance personnel to carry multiple independent testing tools. After arriving at the scene, maintenance personnel must first find the required equipment one by one from the many tool kits they carry. For example, when testing the voltage of the air conditioner circuit, they must first find a voltage detector, connect it, and debug it. After completing the test, they must place the device in place and then find a current detector to measure the current. When measuring parameters such as resistance, they also need to switch to a multimeter. This frequent equipment switching and operation not only consumes a lot of physical energy, but is also prone to errors due to the cumbersome operating steps, affecting the accuracy of the test data. It not only increases the burden of carrying tools, but also prolongs the fault detection time.

[0004] Therefore, it is urgent to provide a kind of air-conditioning maintenance fault detector to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the shortcomings of the above-mentioned prior art and provide a fault detector for air conditioner maintenance.

[0006] In order to solve the above technical problems, a technical solution adopted by the present invention is: to provide a fault detector for air conditioner maintenance, including a main body, a display screen and buttons are respectively installed on the top of the main body, an outlet is opened on the outer wall of the main body, a selection mechanism is provided inside the main body, a battery is installed inside the main body, and a charging port corresponding to the battery is opened on the outer wall of the main body.

[0007] The present invention is further configured as follows: the selection mechanism includes a ratchet that rotates inside the main body, a rotating warehouse is installed on the top of the ratchet, a plurality of placement warehouses are opened inside the rotating warehouse, and a small detector and a wire reel are respectively installed inside the plurality of placement warehouses, and a through hole corresponding to the placement warehouse is opened on the outer wall of the rotating warehouse, a plurality of rotating plates are rotatably connected to the top of the rotating warehouse, and a lifting handle is fixedly connected to the top of the plurality of rotating plates, and a gear ring is installed on the top of the rotating warehouse, the interior of the main body is fixedly connected to a support rod, and a pawl is installed on the top of the support rod, and a fixed rod is fixedly connected to the interior of the main body near the support rod, and the bottom of the pawl is fixedly connected to a mounting block, and a spring is installed between the mounting block and the fixed rod, the interior of the main body is rotatably connected to the rotating rod, the top of the rotating rod is fixedly connected to a rotating gear, and the top of the rotating gear is fixedly connected to the rotating block.

[0008] Through the above technical solution, the staff manually rotates the rotating block to drive the rotating rod to rotate, and the rotating gear on the top of the rotating rod rotates accordingly. The rotating gear cooperates with the ratchet to make the ratchet rotate inside the main body, and then drives the rotating bin installed on the top of the ratchet to rotate. During the rotation of the rotating bin, the pawl interacts with the ratchet. Since there is a spring between the mounting block at the bottom of the pawl and the fixed rod, the spring keeps the pawl in contact with the ratchet. When the ratchet rotates, the pawl will slide on the teeth of the ratchet. When the external force stops, the pawl will be stuck between the teeth of the ratchet to prevent the ratchet from reversing, thereby realizing the one-way positioning of the rotating bin and ensuring that it stays stably in the selected position. The staff can rotate the rotating block according to the inspection items, so that the placement bin inside the rotating bin is rotated to the exit, and then take out the small detector detection head at one end of the internal reel to perform corresponding inspections on the air conditioner. After the inspection is completed, the detection head is released, and the wire of the small detector will be recovered into the placement bin by the reel to facilitate subsequent rotation.

[0009] The present invention is further configured as follows: the small detector includes but is not limited to a voltage detector, a current detector, a multimeter, a clamp ammeter, a megohmmeter and a temperature sensor.

[0010] Through the above technical solution, multiple types of detectors make the detection items of the device comprehensive, making it convenient for staff to perform different types of detection.

[0011] The utility model is further configured such that: the wire outlet of the wire reel is connected to the corresponding through hole.

[0012] Through the above technical solution, the cable can be smoothly led out from the reel through the through hole, avoiding the cables from getting entangled and knotted in the rotating bin, keeping the cables neat, and can be quickly found and pulled out the next time they are used, thereby improving work efficiency.

[0013] The present invention is further configured as follows: the rotating plates are distributed in a ring array with the central axis of the rotating bin as the center, and the rotating plates correspond to the placement bins one by one.

[0014] Through the above technical solution, the operator can quickly find the corresponding rotating plate by pulling the handle, and then find the small detector and reel placed in the warehouse. The one-to-one correspondence makes the operation more directional, eliminating the need to blindly search between multiple warehouses, thereby improving operational efficiency.

[0015] The utility model is further configured as follows: a sealing rubber layer adapted to the opening of the placement bin is fixedly connected to the bottom of the rotating plate.

[0016] The above technical solution can effectively prevent dust, water vapor, etc. from entering the storage compartment, preventing small detectors and wire reels from malfunctioning or performance degradation due to dust accumulation and moisture, thereby extending their service life.

[0017] The utility model is further configured as follows: the tooth profile of the gear ring is an involute tooth profile, the tooth pitch of the gear ring is adapted to the tooth pitch of the rotating gear, and the rotating gear is meshed with the gear ring.

[0018] Through the above technical solution, during the rotation of the rotating bin, the rotation speed can be kept stable without the speed fluctuating. Since the meshing process of the involute tooth profile is relatively smooth, the wear between the tooth surfaces is relatively uniform and small, which extends the service life of the rotating gear and the gear ring, reduces the equipment failure and maintenance frequency caused by gear wear, and improves the reliability and stability of the equipment.

[0019] The beneficial effects of the utility model are as follows:

[0020] 1. The utility model is designed with a selection mechanism. Different placement bins are selected by manually rotating the rotating block. Small detectors and cord reels are installed in the placement bins. The cord reel can also automatically recycle the wires after the detection is completed, which is convenient for subsequent operations. A variety of small detectors can meet the needs of different detection projects, making the detection more comprehensive. The overall design effectively improves the work efficiency of maintenance personnel, reduces the difficulty of operation, and provides great convenience for air conditioning maintenance and detection work.

[0021] 2. The utility model integrates multiple detection functions by accommodating a variety of small detectors such as voltage detectors and current detectors in the selection mechanism inside the main body. This eliminates the need for maintenance personnel to carry multiple independent detection devices, greatly improving the convenience of use. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0028] See also Figure 1-Figure 3 A fault detector for air conditioner maintenance includes a main body 1, a display screen 2 and a button 3 are respectively installed on the top of the main body 1, and an outlet 4 is opened on the outer wall of the main body 1.

[0029] like Figure 4As shown, a selection mechanism 5 is provided inside the main body 1, and the selection mechanism 5 includes a ratchet 501 that rotates inside the main body 1, and a rotating warehouse 502 is installed on the top of the ratchet 501, and a plurality of placement warehouses 503 are provided inside the rotating warehouse 502. Small detectors 504 and wire reels 505 are respectively installed inside the plurality of placement warehouses 503. The small detectors 504 include but are not limited to voltage detectors, current detectors, multimeters, clamp ammeters, megohmmeters and temperature sensors. The various types of detectors make the detection items of the device comprehensive and convenient for staff to perform different types of detection. The outer wall of the rotating warehouse 502 is provided with a through hole 506 corresponding to the placement warehouse 503, and the outlet of the wire reel 505 is connected to the corresponding through hole 506, so that the cable can be smoothly led out from the wire reel 505 through the through hole 506, thereby avoiding the cables from being entangled or knotted in the rotating warehouse 502 and keeping the cables neat. The next time it is used, it can be quickly found and pulled out, which improves work efficiency. The top of the rotating bin 502 is rotatably connected to a plurality of rotating plates 507. The rotating plates 507 are distributed in a circular array with the central axis of the rotating bin 502 as the center, and the rotating plates 507 correspond one-to-one to the placement bin 503. The operator can quickly find the corresponding rotating plate 507 by pulling the handle 508, and then find the small detector 504 and the cord reel 505 in the placement bin 503. The one-to-one correspondence makes the operation more directional, and there is no need to blindly search between multiple bins, which improves operating efficiency. The bottom of the rotating plate 507 is fixedly connected to a sealing rubber layer that is compatible with the opening of the placement bin 503, which can effectively block dust, water vapor, etc. from entering the placement bin 503, preventing the small detector 504 and the cord reel 505 from malfunctioning or performance degradation due to dust accumulation and moisture, thereby extending the service life. The tops of the multiple rotating plates 507 are all fixedly connected to the pulling handle 508.

[0030] like Figure 4As shown, a gear ring 509 is installed on the top of the rotating bin 502. The tooth profile of the gear ring 509 is an involute tooth profile, and the tooth pitch of the gear ring 509 is adapted to the tooth pitch of the rotating gear 516. The rotating gear 516 is meshed with the gear ring 509. During the rotation of the rotating bin 502, the rotation speed can be kept stable without the speed being fast or slow. Since the meshing process of the involute tooth profile is relatively smooth, the wear between the tooth surfaces is relatively uniform and small, which extends the service life of the rotating gear 516 and the gear ring 509 and reduces equipment failure and maintenance caused by gear wear. The maintenance frequency is increased, which improves the reliability and stability of the equipment. The interior of the main body 1 is fixedly connected to a support rod 510, and a pawl 511 is installed on the top of the support rod 510. The interior of the main body 1 is fixedly connected to a fixing rod 512 near the support rod 510, and the bottom of the pawl 511 is fixedly connected to a mounting block 513. A spring 514 is installed between the mounting block 513 and the fixing rod 512. The interior of the main body 1 is rotatably connected to a rotating rod 515, and the top of the rotating rod 515 is fixedly connected to a rotating gear 516, and the top of the rotating gear 516 is fixedly connected to a rotating block 517.

[0031] like Figure 4 As shown, the staff manually rotates the rotating block 517 to drive the rotating rod 515 to rotate, and the rotating gear 516 on the top of the rotating rod 515 rotates accordingly. The rotating gear 516 cooperates with the ratchet 501 to make the ratchet 501 rotate inside the main body 1, thereby driving the rotating bin 502 installed on the top of the ratchet 501 to rotate. During the rotation of the rotating bin 502, the pawl 511 interacts with the ratchet 501. Since there is a spring 514 between the mounting block 513 at the bottom of the pawl 511 and the fixed rod 512, the spring 514 keeps the pawl 511 in contact with the ratchet 501. When the ratchet 501 rotates, the pawl 511 will The pawl 511 slides on the teeth. When the external force stops acting, the pawl 511 will be stuck between the teeth of the ratchet 501 to prevent the ratchet 501 from reversing, thereby realizing the one-way positioning of the rotating bin 502 and ensuring that it stays stably at the selected position. The staff can rotate the rotating block 517 according to the detection items, so that the placement bin 503 inside the rotating bin 502 is rotated to the exit 4, and then take out the small detector 504 detection head at one end of the internal reel 505 to perform corresponding detection on the air conditioner. After the detection is completed, the detection head is released, and the wire of the small detector 504 will be recovered by the reel 505 into the placement bin 503 to facilitate subsequent rotation.

[0032] like Figure 1-Figure 3 As shown, a battery 6 is installed inside the main body 1 , and a charging port 7 corresponding to the battery 6 is opened on the outer wall of the main body 1 .

[0033] When the utility model is in use, when the air conditioner maintenance fault detector is working, the staff manually rotates the rotating block 517 to drive the rotating rod 515 and the top rotating gear 516 to rotate. The rotating gear 516 is meshed with the gear ring 509, and both adopt an involute tooth profile to ensure stable speed and smooth transmission. The rotating gear 516 further drives the ratchet 501 to rotate, thereby rotating the rotating chamber 502 installed on the top of the ratchet 501. During the rotation process, the pawl 511 maintains contact with the ratchet 501 under the action of the spring 514. When the external force stops, the pawl 511 is engaged between the teeth of the ratchet 501, realizing unidirectional positioning of the rotating chamber 502. The staff can rotate the rotating block 517 according to the detection items, and move the storage chamber 503 containing different types of small detectors 504 (such as voltage detectors, multimeters, etc.) and the cord reel 505 in the rotating chamber 502 to the exit 4 of the main body 1, take out the detector probe for detection, and after the detection is completed, the cord reel 505 automatically retracts the wire, and the rotating block 517 is rotated again to perform the required detection.
