Description

Technical Field

[0001] This invention relates to the field of relay protection tester technology, and specifically to a portable relay protection tester. Background Technology

[0002] Microcomputer relay protection testers are an important testing tool for ensuring the safe and reliable operation of power systems. With the rapid development of computer technology, microelectronics technology, and power electronics technology, the continuous introduction of new high-performance relay protection testers based on the latest technological achievements is an inevitable trend of technological progress.

[0003] Existing relay protection testers are typically designed with a single-handed carrying case structure for portability. During transport, they are prone to collisions, which can easily damage the internal components without adequate protection. Furthermore, the testers are easily damaged by the swinging of the arm during hand-carrying. Existing relay protection testers also lack anti-drop protection, which can easily render them unusable if dropped on the ground. Summary of the Invention

[0004] The purpose of this invention is to address the problems of easy collisions during carrying, which can easily damage the internal components of the relay protection tester, and the lack of anti-drop protection function when the instrument is carried and moved around. This invention provides a portable relay protection tester.

[0005] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0006] A portable relay protection tester includes a protection box and a relay protection tester. The protection box consists of a box bottom, a frame, a box top frame, and a box body panel. The frame is located at the four corners of the protection box. A rotating shaft is fixedly connected to the top of the box bottom. The rotating shafts are linearly distributed and located between adjacent frames. The box body panel is sleeved on the rotating shaft. The inner wall of the box body panel is designed with inclined fins. The fins are made of rubber. When the relay protection tester is stored in the protection box, the fins abut against the outside of the relay protection tester. The fins on both sides of the relay protection tester have the same inclination angle.

[0007] It also includes a lid hinged to the top of the protective box, the top of which is hinged to a sleeve via a hinge frame. The sleeve has a sliding hole inside, and a handle is slidably connected inside the sliding hole. A tension spring is provided between the handle and the inner wall of the sliding hole. A latch is provided on the outside of the protective box to lock the lid. A transmission mechanism is provided inside the bottom of the box. The transmission mechanism is driven by the handle and can control the swing of the box body.

[0008] Furthermore, the transmission mechanism includes a transmission cavity located at the bottom of the box, a gear is rotatably mounted inside the transmission cavity, the gear is fixedly connected to the box body plate, a slide rod is slidably connected inside the transmission cavity, the slide rod has a toothed groove on its outer side, the toothed groove meshes with the gear, the toothed groove of the slide rod can drive the gear to rotate one revolution, a transmission rope is fixedly connected to the outer side of the slide rod, the other end of the transmission rope is connected to the handle, and a torsion spring is provided between the box body plate and the rotating shaft.

[0009] Furthermore, the frame has a rope hole inside, through which the transmission rope passes and connects to the handle.

[0010] Furthermore, the bottom, frame, top frame, body panels, and lid of the box are all made of aluminum alloy.

[0011] Furthermore, rubber cushioning pads are provided at both ends of the box body.

[0012] Furthermore, a lower cushioning pad is provided at the top of the bottom of the box, and an upper cushioning pad is provided at the bottom of the box cover. Both the upper and lower cushioning pads are made of sponge.

[0013] Furthermore, the outer sides of both the bottom and the lid of the box are provided with cushioning rubber sleeves.

[0014] Furthermore, an anti-slip groove is provided on the inner side of the handle.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. The present invention provides a relay protection tester by providing rubber fins on the inner wall of the protection box, and the rubber fins are designed to be inclined. This allows the relay protection tester to be clamped in the protection box. When the relay protection tester is carried by hand and a collision occurs, the rubber fins can provide a buffering force to the relay protection tester and prevent damage to the internal components of the relay protection tester.

[0017] 2. The present invention, through the inclined angle of the rubber fins on both sides of the relay protection tester, and the inclined design of the rubber fins, can provide the relay protection tester with different reverse limiting forces, which can effectively prevent the relay protection tester from shaking in the protection box, prevent the relay protection tester from colliding with the protection box due to arm swinging, and improve the transportation stability of the relay protection tester.

[0018] 3. In this invention, when the handle is released, the tension spring drives the handle to return to its original position. The handle then rotates the housing plate through the transmission mechanism. The housing plate rotates 90 degrees, at which point one end of the housing plate rests on the relay protection tester, while the other end and the rubber fins are located outside the device. This effectively protects the protection box. At the same time, the rubber buffer pads and rubber fins at both ends of the housing plate provide cushioning. Furthermore, the rubber fins and one end of the housing plate form a forked shape, which effectively prevents the protection box from rolling after it falls to the ground, further improving the protection effect.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0030] like Figures 1-9As shown, a portable relay protection tester includes a protection box and a relay protection tester 12. The protection box consists of a box bottom 1, a frame 2, a box top frame 3, and a box body 5. The frame 2 is located at the four corners of the protection box. A rotating shaft 4 is fixedly connected to the top of the box bottom 1. The rotating shaft 4 is linearly distributed and located between adjacent frames 2. The box body 5 is sleeved on the rotating shaft 4. The inner wall of the box body 5 is designed with inclined fins. The fins are made of rubber. When the relay protection tester 12 is stored in the protection box, the fins abut against the outside of the relay protection tester 12. The fins on both sides of the relay protection tester 12 have the same tilt angle.

[0031] It also includes a cover 6 hinged to the top of the protective box. The top of the cover 6 is hinged to a sleeve 9 via a hinge frame 8. A sliding hole is provided inside the sleeve 9. A handle 10 is slidably connected inside the sliding hole. A tension spring 11 is provided between the handle 10 and the inner wall of the sliding hole. A latch 7 is provided on the outside of the protective box to lock the cover 6. A transmission mechanism is provided inside the bottom 1 of the box. The transmission mechanism is driven by the handle 10 and can control the swing of the box body plate 5.

[0032] During transport, unlock 7, then open the lid 6. At this time, control the transmission mechanism via handle 10. The transmission mechanism drives the box body plate 5 to swing, as... Figure 9 As shown, the fins are located inside the housing piece 5, and the fins and one end of the housing piece 5 are in a forked shape. Then, the relay protection tester 12 is placed in the protection box. At this time, neither the fins nor the housing piece 5 are in contact with the relay protection tester 12. The relay protection tester 12 is stored without resistance and is easy to store.

[0033] After storage, close the cover 6 and lock it with the latch 7. Then, lift the protection box using the handle 10. Since the protection box and relay protection tester 12 have a certain weight, the protection box causes the cover 6 to descend relative to the handle 10. The cover 6 then causes the sleeve 9 to descend relative to the handle 10. The handle 10 causes the box body plates 5 to swing into a straight line. Multiple sets of box body plates 5 form a single plate, such as... Figure 7 As mentioned above, at this time, the fins are in contact with the outside of the relay protection tester 12. When the protection box is collided during the handling process, the fins can provide sufficient buffering force to the relay protection tester 12, which can prevent damage to the internal components of the relay protection tester 12 and ensure high transportation safety.

[0034] During handling, the user's arm swings as they move, causing the protection box to swing. Because a tension spring 11 is installed between the handle 10 and the sleeve 9, the handle 10 can slide relative to the sleeve 9 during the swing, reducing the amplitude of the swing. Simultaneously, the handle 10 provides rotational force to the box body plate 5 via a transmission mechanism. This allows the fins of the box body plate 5 to press more tightly against the relay protection tester 12, preventing the relay protection tester 12 from swinging relative to the protection box. Furthermore, since the fins on both sides of the relay protection tester 12 have the same tilt angle, ... Figure 7 As shown, due to the inclined fin design, the fins on both sides can provide the relay protection tester 12 with limiting forces in opposite directions, which can further prevent the relay protection tester 12 from shaking relative to the protection box, resulting in high transportation stability.

[0035] When the handle 10 is released during handling, the tension spring 11 causes the handle 10 to retract into the sleeve 9. This, through the transmission mechanism, causes the box body plate 5 to swing 90 degrees. Figure 8 As shown, the housing plate 5 swings until it is vertical with the relay protection tester 12. At this time, one end of the housing plate 5 rests on the relay protection tester 12, while the other end and the fins are located outside. This can effectively protect the protection box. At the same time, the two ends of the housing plate 5 and the fins act as a buffer. The fins and one end of the housing plate 5 form a tree branch shape, which can effectively prevent the protection box from rolling after it lands, further improving the protection effect. It has high anti-detachment protection performance and can further prevent damage to the relay protection tester 12.

[0036] like Figures 2-5 As shown, in some embodiments, the transmission mechanism includes a transmission cavity 15 formed at the bottom of the box 1. A gear 16 is rotatably mounted inside the transmission cavity 15. The gear 16 is fixedly connected to the box body plate 5. A slide rod 17 is slidably connected inside the transmission cavity 15. A toothed groove is formed on the outer side of the slide rod 17. The toothed groove meshes with the gear 16. The toothed groove of the slide rod 17 can drive the gear 16 to rotate one revolution. A transmission rope 18 is fixedly connected to the outer side of the slide rod 17. The other end of the transmission rope 18 is connected to the handle 10. A torsion spring 19 is provided between the box body plate 5 and the rotating shaft 4.

[0037] Lifting the protection box via handle 10 causes the protection box and relay protection tester 12 to have a certain weight. The protection box then lowers the cover 6 relative to handle 10, which in turn lowers the sleeve 9 relative to handle 10. Handle 10, via transmission rope 18, drives slide rod 17 to slide. Slide rod 17, via toothed grooves, drives gear 16 to rotate. Gear 16 drives the housing plate 5 to rotate, causing the housing plate 5 to swing to a straight line. Multiple housing plates 5 form a single plate, such as... Figure 7As mentioned above, at this time, the fins are in contact with the outside of the relay protection tester 12. When the protection box is collided during the handling process, the fins can provide sufficient buffering force to the relay protection tester 12, which can prevent damage to the internal components of the relay protection tester 12 and ensure high transportation safety.

[0038] During the carrying process, the arm of the person carrying the protective box will swing due to their movement. The arm will cause the protective box to swing. Since there is a tension spring 11 between the handle 10 and the sleeve 9, the handle 10 can slide relative to the sleeve 9 during the swing of the protective box. The handle 10 can reduce the swing amplitude of the protective box. While the handle 10 slides relative to the sleeve 9, the handle 10 continues to drive the slide rod 17 to slide through the transmission rope 18. The slide rod 17 drives the gear 16 to rotate through the tooth groove. The gear 16 drives the box body plate 5 to continue to rotate. The box body plate 5 can make the fins press more tightly on the relay protection tester 12, which can prevent the relay protection tester 12 from swinging relative to the protective box, resulting in high transportation stability.

[0039] During the lifting process, if the handle 10 is released, the tension spring 11 will cause the handle 10 to retract into the sleeve 9. At this time, the transmission rope 18 will be free of tension, and the torsion spring 19 will cause the housing plate 5 to swing back 90 degrees. Figure 8 As shown, the housing plate 5 swings until it is vertical with the relay protection tester 12. At this time, one end of the housing plate 5 rests on the relay protection tester 12, while the other end and the fins are located outside. This can effectively protect the protection box. At the same time, the two ends of the housing plate 5 and the fins act as a buffer. The fins and one end of the housing plate 5 form a tree branch shape, which can effectively prevent the protection box from rolling after it lands, further improving the protection effect. It has high anti-detachment protection performance and can further prevent damage to the relay protection tester 12.

[0040] like Figure 5 As shown, in some embodiments, the frame 2 has a rope hole inside, through which the transmission rope passes and connects to the handle 10.

[0041] This design guides the transmission of the drive rope 18, ensuring stable transmission.

[0042] like Figure 1 As shown, in some embodiments, the bottom 1, frame 2, top frame 3, body 5, and lid 6 are all made of aluminum alloy, which improves the overall structural strength of the protective box and provides good protection.

[0043] like Figure 6 As shown, in some embodiments, rubber buffer pads are provided at both ends of the housing piece 5.

[0044] During the lifting process, if the handle 10 is released, the tension spring 11 will cause the handle 10 to retract into the sleeve 9. At this time, the transmission rope 18 will be free of tension, and the torsion spring 19 will cause the housing plate 5 to swing back 90 degrees. Figure 8 As shown, the housing plate 5 swings to be vertical with the relay protection tester 12. At this time, one end of the housing plate 5 rests on the relay protection tester 12, while the other end and the fins are located outside, which can effectively protect the protection box. At the same time, the rubber buffer pads at both ends of the housing plate 5 and the fins play a buffering role. Furthermore, the fins and one end of the housing plate 5 form a tree branch shape, which can effectively prevent the protection box from rolling after landing, further improving the protection effect. It has high anti-detachment protection performance and can further prevent damage to the relay protection tester 12.

[0045] Meanwhile, rubber buffer pads are provided at both ends of the box plate 5, so that when multiple sets of box plates 5 swing in a straight line, adjacent box plates 5 can be more tightly combined, improving the protective effect. In addition, the rubber buffer pads provide a certain amount of expansion and contraction during swinging, so that they do not interfere with each other.

[0046] like Figure 2 As shown, in some embodiments, a lower cushioning pad 14 is provided on the top of the box bottom 1, and an upper cushioning pad 13 is provided on the bottom of the box cover 6. Both the upper cushioning pad 13 and the lower cushioning pad 14 are made of sponge.

[0047] This design enables buffer protection at both ends of the relay protection tester 12, further improving the protection effect.

[0048] like Figure 1 As shown, in some embodiments, the outer sides of the bottom 1 and the cover 6 are provided with cushioning rubber sleeves. This design ensures that when the handle 10 is released, the bottom 1 or the cover 6 will not deform when it collides with the ground, thus improving the service life of the protective box.

[0049] like Figure 1 As shown, in some embodiments, the inner side of the handle 10 is provided with an anti-detachment groove. The anti-detachment groove design makes the protective case handle more stable and reduces the probability of slipping out of the hand.

[0050] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
