Description

Technical Field

[0001] This invention relates to the field of leakage current monitoring technology, specifically a portable intelligent multi-channel leakage current monitor. Background Technology

[0002] Leakage current detectors are key equipment for electrical safety testing, widely used in construction, industrial production, and outdoor operations. They can monitor leakage current in circuits in real time, preventing safety accidents such as electric shock and fire. With the diversification of electrical equipment and the increasing mobility of usage scenarios, higher demands are placed on the portability, deployment efficiency, and multi-channel monitoring capabilities of leakage current detectors. They need to be easy to carry and transport, and able to quickly deploy monitoring operations, while ensuring stable connections across multiple circuits to avoid detection interruptions due to movement or vibration.

[0003] Currently, traditional portable leakage current detectors mostly have separate storage boxes and detectors. After opening the storage box, the detector needs to be manually removed and supported separately, which is cumbersome and inefficient when used in mobile monitoring scenarios. Some integrated storage devices can accommodate the detector, but require additional operation of lifting buttons or knobs to remove it. They cannot achieve linkage between the opening and closing of the cover and the lifting of the detector, and the support status needs to be readjusted after removal. In view of this, we propose a portable intelligent multi-channel leakage current detector. Summary of the Invention

[0004] The main objective of this invention is to provide a portable intelligent multi-channel leakage current monitor that can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention proposes a portable intelligent multi-channel leakage current monitor, comprising a storage box and a monitor body. A guide rail is fixedly connected to the inner wall of the storage box, and a lifting rod is slidably connected to the outer wall of the guide rail. A placement plate is fixedly connected to the top of the lifting rod, and a quick-release assembly is provided on the top of the placement plate. The quick-release assembly includes: A placement column is fixedly connected to the top of the placement plate, and a fixing seat is fixedly connected to the top of the placement plate. A guide rod is slidably connected to the inner wall of the fixed base, and a simulated clamping plate is fixedly connected to the outer wall of the guide rod; A connecting plate is fixedly connected to the end of the guide rod away from the simulation clamping plate, and a linkage plate is fixedly connected to the outer wall of the connecting plate; An elliptical disk is rotatably connected to the top of the placement plate, and the elliptical disk has an abutment notch.

[0006] Preferably, an abutment rod is fixedly connected to the inner wall of the linkage plate, a synchronization rod is fixedly connected to the outer wall of the elliptical disk, and an adjustment plate is fixedly connected to the end of the synchronization rod away from the elliptical disk, so that the abutment rod can abut into the abutment notch.

[0007] Preferably, the fixed base and the simulated clamping plate are elastically connected by a first spring, the abutting rod passes through the fixed base and is slidably connected to the fixed base, the clamping surface of the simulated clamping plate is adapted to the outer shape of the monitor body, and the top of the placement plate is rotatably connected to a synchronizing rod.

[0008] Preferably, the main body of the monitor is provided with an auxiliary component, the auxiliary component includes an auxiliary slot, the bottom of the main body of the monitor is provided with an auxiliary slot, the auxiliary slot is provided with a storage hole, and the auxiliary slot is provided with an interface.

[0009] Preferably, a guide slide bar is slidably connected to the inner wall of the receiving hole, and an mounting plate is fixedly connected to the outer wall of the guide slide bar. The auxiliary groove and the mounting plate are elastically connected by a second spring.

[0010] Preferably, an anti-disengagement block is fixedly connected to the top of the mounting plate. The anti-disengagement block has a cable placement groove. After the plug and interface are connected, the second spring causes the anti-disengagement block to abut against the plug, thereby ensuring the connection between the plug and the interface. The cable placement groove is used to place the cable of the plug.

[0011] Preferably, the storage box is provided with a lifting component, the lifting component includes a guide rail plate, the guide rail plate is provided with a guide rail groove, the guide rail groove is divided into a straight end and an arc end, and the two are interconnected.

[0012] Preferably, a first sliding shaft is provided on the guide rail groove, and a second sliding shaft is provided on the guide rail groove. A support frame is fixedly connected to the outer wall of the first sliding shaft. Both the first and second sliding shafts can slide or rotate in the guide rail groove.

[0013] Preferably, a cover plate is fixedly connected to the outer wall of the supporting frame, a push sleeve is fixedly connected to the outer wall of the second sliding shaft, the outer wall of the second sliding shaft is fixedly connected to the inner wall of the supporting frame, the outer wall of the push sleeve is slidably connected to the inner wall of the lifting rod, and the push sleeve is simultaneously connected to the second sliding shafts on both sides.

[0014] Preferably, a storage frame is fixedly connected to the inner wall of the storage box, and the storage frame is used to store other accessories.

[0015] This invention provides a portable intelligent multi-channel leakage current monitor. It has the following advantages: (1) When the portable intelligent multi-channel leakage current monitor moves upward and rotates the cover plate, the support frame drives the first sliding shaft and the second sliding shaft to move along the straight end and arc end of the guide rail groove, pushing the sleeve rod to drive the lifting rod to rise along the guide rail, so that the placement plate and the monitor body automatically rise out of the storage box; there is no need to operate the lifting mechanism separately, the monitor can be deployed by opening the cover plate, and can be stored synchronously by closing the cover plate, which greatly improves the convenience of operation in mobile monitoring scenarios.

[0016] (2) The portable intelligent multi-channel leakage current monitor can rotate the elliptical disk through the rotating adjustment disk and the synchronous rod. The abutment notch of the elliptical disk pushes the abutment rod to move, thereby moving the simulated clamp away from the main body of the monitor, making it easy to remove the monitor and carry it separately. Conversely, after the elliptical disk is reset, the first spring pushes the simulated clamp to automatically clamp and fix the monitor. With the insertion and positioning of the placement column, it ensures that there is no shaking when storing, taking into account both portability and storage stability.

[0017] (3) When wiring the portable intelligent multi-channel leakage current monitor, push the mounting plate to move the anti-dislodgement block away from the interface to facilitate plug insertion; after releasing, the second spring pulls the anti-dislodgement block to press against the plug, preventing the plug from falling off due to vibration or cable pulling during the monitoring process; at the same time, placing the cable tray can organize the routing of multiple sets of cables, prevent the cables from getting tangled and knotted, ensure the continuous and stable multi-channel leakage current monitoring process, and reduce connection failures.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-7This invention proposes a portable intelligent multi-channel leakage current monitor, including a storage box 1 and a monitor body 10. The storage box 1 is made of high-strength ABS material, which is lightweight, drop-resistant, waterproof, and dustproof, suitable for mobile monitoring scenarios such as outdoor and construction sites. The internal space is reasonably arranged, which can simultaneously store the monitor body 10 and accessories. The bottom of the monitor body 10 is provided with four sets of support feet. The inner wall of the storage box 1 is fixedly connected to a guide rail 2, which has two sets to facilitate the lifting and lowering of the lifting rod 3. The outer wall of the guide rail 2 is slidably connected to the lifting rod 3, and the lifting rod 3 has an avoidance groove. The outer wall of the push sleeve 77 is slidably connected to the inner wall of the avoidance groove. The top of the lifting rod 3 is fixedly connected to a placement plate 4, and the top of the placement plate 4 is provided with a quick-release assembly 5, which includes a placement column 51. The top of the placement plate 4 is fixedly connected to the placement column 51, and the top of the placement column 51 has a groove to facilitate contact with the bottom of the monitor body 10. The support frame of the part is inserted. The top of the placement plate 4 is fixedly connected to the fixed seat 52. The inner wall of the fixed seat 52 is slidably connected to the guide rod 53. The outer wall of the guide rod 53 is fixedly connected to the simulated clamping plate 54. The simulated clamping plate 54 is an arc-shaped plastic plate with anti-slip rubber pads pasted on the inner wall. The clamping surface is completely adapted to the outer contour of the main body 10 of the monitor, which ensures stable clamping and avoids scratching the body. The end of the guide rod 53 away from the simulated clamping plate 54 is fixedly connected to the connecting plate 55. Two sets of guide rods 53 are connected to one set of connecting plates 55 at the same time. The outer wall of the connecting plate 55 is fixedly connected to the linkage plate 56. The linkage plate 56 is welded and fixed to the connecting plate 55. The inner wall is tightly connected to the abutment rod 59, which transmits power stably. The top of the placement plate 4 is rotatably connected to the elliptical disk 57. The elliptical disk 57 has abutment notches 58. Four sets of abutment notches 58 are set and distributed on the four sides of the elliptical disk 57, which can accurately engage the abutment rod 59 and realize the switching between clamping and releasing.

[0024] In an embodiment of the present invention, an abutment rod 59 is fixedly connected to the inner wall of the linkage plate 56. The abutment rod 59 is a cylindrical metal rod, one end of which is welded to the linkage plate 56, and the other end is rounded and chamfered to facilitate sliding into or out of the abutment notch 58. A synchronization rod 510 is fixedly connected to the outer wall of the elliptical disk 57. The synchronization rod 510 is a solid metal rod, welded to the elliptical disk 57, and can accurately transmit rotational force to ensure that the elliptical disk 57 rotates synchronously. An adjustment disc 511 is fixedly connected to the end of the synchronization rod 510 away from the elliptical disk 57. The abutment rod 59 can... The adjusting plate 511 is a circular plastic plate with anti-slip texture on the surface, which is convenient for manual rotation and can be operated without tools. The fixed base 52 and the simulated clamping plate 54 are elastically connected by a first spring. In its natural state, the first spring pushes the simulated clamping plate 54 to pre-tighten towards the main body 10 of the monitor to ensure stable clamping. The abutting rod 59 passes through the fixed base 52 and is slidably connected to the fixed base 52. The clamping surface of the simulated clamping plate 54 is adapted to the outer shape of the main body 10 of the monitor. The top of the placement plate 4 is rotatably connected to the synchronous rod 510.

[0025] Furthermore, the main body 10 of the monitor is provided with an auxiliary component 6, which includes an auxiliary groove 61. The auxiliary groove 61 is located at the bottom of the main body 10. The auxiliary groove 61 has a storage hole 62 and an interface. The auxiliary groove 61 is a rectangular groove with built-in multi-channel monitoring interfaces, which facilitates the simultaneous connection of multiple sets of lines for leakage detection. A guide rod 63 is slidably connected to the inner wall of the storage hole 62. The storage hole 62 is a circular hole that fits with the guide rod 63 to ensure smooth sliding of the guide rod 63. A mounting plate 64 is fixedly connected to the outer wall of the guide rod 63. The auxiliary groove 61 and the mounting plate 64 are connected by a second spring. The connection is flexible. In its natural state, the second spring pulls the anti-disengagement block 65 to press it tightly against the plug, ensuring a stable connection. The anti-disengagement block 65 is fixedly connected to the top of the mounting plate 64. The anti-disengagement block 65 is a plastic block that is fixed to the mounting plate 64 with screws. The anti-disengagement block 65 has a cable placement groove 66. The cable placement groove 66 is an arc-shaped groove that matches the outer diameter of the cable. It can straighten the cable route and prevent the cable from getting tangled or pulled, which could cause the plug to loosen. After the plug and the interface are connected, the second spring causes the anti-disengagement block 65 to abut against the plug, thereby ensuring the connection between the plug and the interface. The cable placement groove 66 is used to place the cable in the plug.

[0026] Furthermore, the storage box 1 is provided with a lifting component 7, which includes a guide rail plate 71 and a guide rail groove 72. The guide rail plate 71 is a rectangular metal plate that is welded and fixed to the inner wall of the storage box 1. The straight section and the curved section of the guide rail groove 72 are smoothly connected to ensure that the sliding shaft moves without jamming. The guide rail groove 72 has a straight end and a curved end, and the two are interconnected. The straight end of the guide rail groove 72 is used to drive the support frame 75 to rise and fall vertically and to drive the cover plate 76 to rotate and open and close. The two are seamlessly interconnected to realize linkage operation. A first sliding shaft 73 and a second sliding shaft 74 are provided on the guide rail groove 72. Both the first sliding shaft 73 and the second sliding shaft 74 are cylindrical metal shafts with smooth surfaces, which can slide and rotate smoothly in the guide rail groove 72. The outer wall of the first sliding shaft 73 is fixedly connected to the support frame 75.

[0027] Furthermore, a cover plate 76 is fixedly connected to the outer wall of the support frame 75. The cover plate 76 is a plastic cover that fits the storage box 1. The surface is provided with a non-slip grip for easy manual operation. When closed, it can seal the storage box 1, making it dustproof and waterproof. A push sleeve rod 77 is fixedly connected to the outer wall of the second sliding shaft 74. The outer wall of the second sliding shaft 74 is fixedly connected to the inner wall of the support frame 75. The push sleeve rod 77 is a hollow metal sleeve. The inner wall is adapted to the clearance groove of the lifting rod 3, which can drive the lifting rod 3 to rise and fall synchronously. The outer wall of the push sleeve rod 77 is slidably connected to the inner wall of the lifting rod 3. The push sleeve rod 77 is also connected to the second sliding shafts 74 on both sides. A storage frame 8 is fixedly connected to the inner wall of the storage box 1. The storage frame 8 is used to classify and store monitoring cables, plugs and other accessories to avoid mess and loss.

[0028] In this invention, during use, by moving the cover plate 76 upward, the supporting curved frame 75 is driven to move linearly, causing the first sliding shaft 73 and the second sliding shaft 74 to move linearly synchronously. At this time, the first sliding shaft 73 moves to the highest point of the straight end of the guide rail groove 72, while the second sliding shaft 74 moves to the connection between the straight end and the arc-shaped end. Then, the cover plate 76 is rotated to make it rotate around the first sliding shaft 73, causing the second sliding shaft 74 to move to the highest point of the arc-shaped end, as shown. Figure 3 As shown, the movement of the second sliding shaft 74 will drive the push sleeve 77 to move. In conjunction with the avoidance groove on the lifting rod 3, the position of the lifting rod 3 is changed by the push sleeve 77. Thus, while opening the cover plate 76, the placement plate 4 automatically rises from the storage box 1, which facilitates the operation of the monitoring instrument body 10. When wiring is required, the mounting plate 64 is moved to move the anti-disengagement block 65 away from the interface, making it easier to insert the plug into the interface. At this time, the mounting plate 64 is released, and the second spring resets the anti-disengagement block 65 to abut the plug, thereby ensuring the plug is connected to the interface. The cable is placed in the cable tray 66. When the main body 10 of the monitor is taken away separately, the elliptical disk 57 is rotated 90 degrees asynchronously by rotating the adjustment disk 511 and cooperating with the synchronization rod 510. The rotating elliptical disk 57 will first push the abutment rod 59 to slide out of the current abutment notch 58. The curved surface of the rotating elliptical disk 57 will push the abutment rod 59 to move horizontally until the abutment rod 59 slides back into another set of abutment notches 58. Through the horizontal movement of the abutment rod 59, the linkage plate 56 moves horizontally synchronously, driving the connecting plate 55 to move. In turn, the guide rod 53 drives the simulation clamping plate 54 to separate from the outer wall of the main body 10 of the monitor, releasing the clamping state of the main body 10 of the monitor, making it convenient for us to remove the main body 10 of the monitor.
