Technical Field

[0001] This utility model belongs to the field of relay inspection technology, specifically relating to a 10kV relay inspection device. Background Technology

[0002] A relay is an electrical control device that causes a predetermined step change in the controlled quantity in the electrical output circuit when the input quantity changes to a specified level. During the use of relays, it is necessary to periodically inspect and process them using an inspection device.

[0003] Although the existing inspection device can perform routine 10kV relay inspections, it still has the following drawbacks in actual use: when not in use, the jacks for connecting the multimeter probes are exposed, making them prone to dust accumulation, which reduces the effectiveness of the inspection device. In addition, the multimeter can only be placed flat on a flat surface, which cannot meet the needs of different inspection personnel to observe the test data at suitable angles. Therefore, a 10kV relay inspection device is needed. Utility Model Content

[0004] The purpose of this invention is to provide a 10kV relay inspection device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a 10kV relay inspection device, comprising a multimeter body, a baffle fixedly connected to the bottom end of the multimeter body, a mating plate fixedly connected to the front top of the baffle, a protective cover slidably fitted on the outer side of the multimeter body, a mating groove adapted to the mating plate being opened on one end of the protective cover facing the mating plate, two symmetrically arranged key strips fixedly connected to the inner wall of the protective cover, the key strips sliding in the key grooves opened on the outer wall of the multimeter body, and linkage adjustable support components installed on both side walls of the multimeter body, the linkage adjustable support components being connected to the outer wall of the protective cover.

[0006] In a preferred embodiment, the linkage adjustable support assembly includes an outer support rod rotatably connected to the outer wall of the multimeter body and at a position away from the baffle via a rotating shaft. The outer support rod is movably sleeved on the outside of the inner support rod. A rubber ball is fixed to the bottom end of the inner support rod. A first hand-tightening screw is threadedly connected to the outer wall of the outer support rod near its bottom end. The end of the first hand-tightening screw, after being tightened, abuts against the outer wall of the inner support rod.

[0007] In a preferred embodiment, a gear is also provided between the outer support rod and the outer wall of the multimeter body, which is fixed to the outside of the rotating shaft. A toothed plate is meshed with the outer side of the gear. A guide plate with an isosceles trapezoidal cross-section is fixed to the rear side wall of the toothed plate. A guide rail is slidably sleeved on the outer side of the guide plate. The guide rail is fixed to the outer wall of the multimeter body.

[0008] In a preferred embodiment, a transmission column is fixedly connected to the top of the toothed plate, and one end of the transmission column facing the protective cover is movably connected to a transmission groove with a Z-shaped vertical cross-section. The transmission groove is formed on the outer wall of the protective cover.

[0009] In a preferred embodiment, the inner width of the transmission groove is equal to the diameter of the transmission column.

[0010] In a preferred embodiment, a second hand-tightening screw is threaded onto the transmission column, and the end of the second hand-tightening screw, after being tightened, abuts against the inner wall of the transmission groove.

[0011] Compared with the prior art, the 10kV relay inspection device provided by this utility model has at least the following beneficial effects:

[0012] In this invention, when using the 10kV relay inspection device, after the protective cover is slid away from the baffle and moved to its end, and with the help of the transmission column and transmission groove, the protective cover is opened to its limit. At this time, the gear plate moves downward with the cooperation of the transmission column and transmission groove, and drives the gear, thereby causing the rotating shaft to rotate the outer support rod at a fixed angle, forming an obtuse angle with the rear side wall of the multimeter body. This satisfies the requirement that the multimeter body is tilted when placed on a flat surface, meeting the needs of the inspectors. In addition, by loosening the first hand-tightened screw, the inner support rod can be supported... The length of the outer support rod can be adjusted by extending or retracting it. After adjustment, the first hand-tightened screw can be tightened to support the multimeter body at different tilt angles, meeting the needs of different inspectors. Conversely, when the protective cover moves towards the baffle, and the mating groove fits onto the mating plate to protect the insertion holes on the multimeter body, the transmission groove drives the transmission column, causing the transmission column to move the gear plate upward. This causes the rotating shaft connected by the gear to rotate the outer support rod and retract it to the outer wall of the multimeter body, thus achieving the purpose of synchronous storage of the support structure. In actual use, it is convenient, fast, and efficient. Attached Figure Description

[0019] The present invention will be further described below with reference to the embodiments.

[0020] To make the objectives, technical solutions, and advantages of the present utility model embodiments clearer, the technical solutions of the present utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present utility model, but not all embodiments. All other embodiments obtained by those skilled in the art based on the described embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention. Example

[0022] Although the existing inspection device can perform routine 10kV relay inspections, it still has the following drawbacks in actual use: when not in use, the jacks for connecting the multimeter probes are exposed, which makes it easy for dust to accumulate in the jacks, thus making the inspection device less effective. In addition, the multimeter can only be placed flat on a flat surface, which makes it impossible to meet the needs of different inspection personnel to observe and test data from different angles.

[0023] For this purpose, please refer to Figure 1-5This utility model provides a 10kV relay inspection device, including: a multimeter body 1, a baffle 11 fixedly connected to the bottom end of the multimeter body 1, a mating plate 12 fixedly connected to the front side of the top end of the baffle 11, a protective cover 13 slidably sleeved on the outer side of the multimeter body 1, a mating groove 14 adapted to the mating plate 12 is opened on one end of the protective cover 13 facing the mating plate 12, two symmetrically arranged key strips 15 are fixedly connected to the inner wall of the protective cover 13, the key strips 15 slide in the key grooves 151 opened on the outer wall of the multimeter body 1, and a linkage adjustable support assembly 2 is installed on both side walls of the multimeter body 1, the linkage adjustable support assembly 2 is connected to the outer wall of the protective cover 13.

[0024] The working principle of the multimeter body 1 is existing technology and will not be described in detail.

[0025] Further as Figure 1-5 As shown, it is worth noting that in order to enable the protective cover 13 to open and the angle support structure to unfold simultaneously, a linkage adjustable support assembly 2 is provided. This assembly includes an outer support rod 28 rotatably connected to the outer wall of the multimeter body 1, away from the baffle 11, via a pivot 27. The outer support rod 28 is movably sleeved on the outside of the inner support rod 29. A rubber ball 210 is fixed to the bottom end of the inner support rod 29. A first hand-tightening screw 211 is threadedly connected to the outer wall of the outer support rod 28, near its bottom end. The end of the first hand-tightening screw 211, after being tightened, abuts against the outer wall of the inner support rod 29. A connection is also provided between the outer support rod 28 and the outer wall of the multimeter body 1, fixed to the outside of the pivot 27. The gear 26 has a gear plate 23 meshing with its outer side. The rear side wall of the gear plate 23 is fixedly connected to a guide plate 24 with an isosceles trapezoidal cross section. The outer side of the guide plate 24 is slidably fitted with a guide rail 25. The guide rail 25 is fixedly connected to the outer wall of the multimeter body 1. The top of the gear plate 23 is fixedly connected to a transmission column 22. One end of the transmission column 22 facing the protective cover 13 is movably connected to a transmission groove 21 with a Z-shaped vertical cross section. The transmission groove 21 is opened on the outer wall of the protective cover 13. The inner width of the transmission groove 21 is equal to the diameter of the transmission column 22. A second hand-tightening screw 212 is threadedly connected to the transmission column 22. The end of the second hand-tightening screw 212 after being locked is pressed against the inner wall of the transmission groove 21.

[0026] The rear sidewall of the guide plate 24 is flush with the outer wall surface of the protective cover 13. When the toothed plate 23 moves upward through the guide plate 24, the rear sidewall of the guide plate 24 is movably attached to the outer wall of the protective cover 13.

[0027] The inner width of the transmission groove 21 is equal to the diameter of the transmission column 22, in order to prevent the toothed plate 23 from moving up and down.

[0028] The rubber ball 210 can cushion the overall weight of the multimeter body 1. When the rubber ball 210 is squeezed and deformed, it can increase the friction between the rubber ball and the flat body, ensuring the stability of the multimeter body 1 when it is placed.

[0029] The inner side of the outer support rod 28 has an active channel that cooperates with the inner support rod 29. The length of the inner support rod 29 is the same as the length of the outer support rod 28. The inner support rod 29 is movably inserted into the active channel, which is the same as the form of the telescopic rod.

[0030] In summary: When using this 10kV relay inspection device, after sliding the protective cover 13 away from the baffle 11 to its end, and with the coordination of the transmission column 22 and the transmission groove 21, the protective cover 13 is opened to its limit. At this time, the toothed plate 23 moves downward with the cooperation of the transmission column 22 and the transmission groove 21, and drives the gear 26. This causes the rotating shaft 27 to drive the outer support rod 28 to rotate at a fixed angle, forming an obtuse angle with the rear side wall of the multimeter body 1. This satisfies the requirement that the multimeter body 1 is tilted when placed on a flat surface, meeting the needs of the inspectors. In addition, by loosening the first hand-tightened screw 211, the inner support rod 29 can be supported by the outer support rod. The length of the multimeter body 1 can be adjusted by extending or retracting the internal structure. After adjustment, the first hand-tightened screw 211 can be tightened to support the multimeter body 1 at different tilt angles to meet the needs of different inspectors. Conversely, when the protective cover 13 moves towards the baffle 11 and the mating groove 14 is fitted onto the mating plate 12 to protect the insertion hole on the multimeter body 1, the transmission groove 21 drives the transmission column 22 to move the transmission column 22 to move the gear plate 23 upward. This causes the rotating shaft 27 connected to the gear 26 to rotate the outer support rod 28 and retract it to the outer wall of the multimeter body 1, thus achieving the purpose of synchronous storage of the support structure. In actual use, it is convenient, fast and efficient.
