Description

Technical Field

[0001] This utility model relates to the technical field of busbar trunking inspection, and in particular to an adjustable inspection device. Background Technology

[0002] Busbar trunking is widely used in industry and high-rise buildings due to its advantages such as low impedance, low voltage drop, compact structure, high load-bearing capacity, good fire resistance, simple installation, convenient maintenance, and safety and reliability. During the production of busbar trunking, insulation testing is required to check for short circuits between copper busbars or connections to external wiring, or to test the insulation layer's ability to withstand high voltage. Traditionally, this involves manually testing two copper busbars at random with two handheld testing cables. This process is tedious, time-consuming, and labor-intensive, and can easily lead to inconsistent results when there are many copper busbars inside the busbar.

[0003] Although there is currently a type of busbar copper busbar socket with Chinese patent number CN201720423335.3 that can be used for testing busbars, this testing equipment can only adapt to the corresponding busbar width when performing power frequency withstand voltage testing on dual-channel busbars after production. It cannot adjust the testing width, resulting in a limited range of applications. Utility Model Content

[0004] The purpose of this invention is to improve the problem that existing testing equipment can only adapt to the corresponding busbar width and cannot adjust the testing width, resulting in a limited range of applications, and to provide an adjustable testing equipment.

[0007] The adjustment mechanism includes an adjustment component, a push block, and a rotating assembly. The push block is movably disposed inside the housing. The first end of the rotating assembly is mounted on the push block, and the second and third ends of the rotating assembly are respectively rotatably engaged with two second conductive components.

[0008] The adjusting member is rotatably mounted on the housing and cooperates with the pushing block. The pushing block has a first moving position and a second moving position in a first direction. In the first moving position, the two second conductive members move closer to each other in a second direction. In the second moving position, the two second conductive members move further apart in a second direction.

[0009] In one embodiment, the rotating assembly includes a support shaft, a first transmission block, a second transmission block, a first rotating shaft, and a second rotating shaft. The support shaft is mounted on a push block, and the first ends of the first and second transmission blocks are both sleeved outside the support shaft and rotatably connected to the support shaft.

[0010] The second ends of the first transmission block and the second transmission block are respectively sleeved on the first rotating shaft and the second rotating shaft, and the first transmission block is rotatably connected to the first rotating shaft, and the second transmission block is rotatably connected to the second rotating shaft; the first rotating shaft is mounted on one of the second conductive components, and the second rotating shaft is mounted on the other second conductive component.

[0011] In one embodiment, the second conductive element has a mounting groove, at least a portion of the first transmission block and the second transmission block are located in the mounting groove, the first rotating shaft and the second rotating shaft are mounted in the mounting groove, and the upper and lower ends of the first rotating shaft and the second rotating shaft are connected to the second conductive element.

[0012] In one embodiment, the angle between the first transmission block and the second transmission block is less than 180 degrees.

[0013] In one embodiment, the rotating assembly has two sets, which are respectively mounted on the upper and lower ends of the push block.

[0014] In one embodiment, the housing has a first guide groove located at the top and / or bottom of the housing, the first guide groove extending along a second direction, and the second conductive element having a first guide block that mates with the first guide groove.

[0015] In one embodiment, the adjusting member includes a knob and a push shaft. The knob is fixedly connected to the push shaft. The outer wall of the push shaft has an external thread. The push block has an adjusting hole with an internal thread. The push shaft is threadedly connected to the push block.

[0016] The outer wall of the push block has a second guide block, which extends along a first direction, and the outer shell has a second guide groove that slides with the second guide block.

[0017] In one embodiment, a limiting groove is provided between the knob and the push shaft, the limiting groove extending circumferentially along the knob, and the housing has a limiting block that abuts against the side wall of the limiting groove.

[0018] In one embodiment, the second conductive element includes a movable plate and an elastic element, the movable plate being rotatably connected to a rotating assembly, and the elastic element being mounted on the side wall of the movable plate.

An adjusting component is rotatably mounted on the housing and engages with a pushing block. The adjusting component adjusts the position of the pushing block in the first direction, giving it a first moving position and a second moving position. In the first moving position, the pushing block drives the two second conductive elements to move closer together in the second direction. When the pushing block moves to the second moving position, it drives the two second conductive elements to move away from each other in the second direction. Therefore, the two second conductive elements have a moving path that allows them to move closer or further apart, thus adjusting the distance between the second and first conductive elements. If the width of the busbar trough is within the range of the adjusting distance of the second conductive element, then the adjustable inspection device can adjust the detection width, adapting it to busbar troughs of different widths, thereby improving the applicable range of the adjustable inspection device.

[0037] This utility model proposes an adjustable testing device 100, such as... Figures 1 to 7As shown, the device includes a housing 1, an adjustment mechanism 4, a first conductive element 2, and two second conductive elements 3. The first conductive element 2 is mounted on the housing 1, and the two second conductive elements 3 are movably disposed on the housing 1, with the first conductive element 2 positioned between the two second conductive elements 3. The adjustment mechanism 4 includes an adjustment element 41, a push block 43, and a rotating assembly 440. The push block 43 is movably disposed inside the housing 1. The first end of the rotating assembly 440 is mounted on the push block 43, and the second and third ends of the rotating assembly 440 are respectively rotatably engaged with the two second conductive elements 3. The adjustment element 41 is rotatably disposed on the housing 1 and engages with the push block 43. The push block 43 has a first moving position and a second moving position in a first direction. In the first moving position, the two second conductive elements 3 are close to each other in a second direction, and in the second moving position, the two second conductive elements 3 are far apart in a second direction.

[0038] Specifically, the outer casing 1 is used to support or install the first conductive element 2, the second conductive element 3, and the adjusting mechanism 4. The first conductive element 2 is fixedly connected to the outer casing 1, and the two second conductive elements 3 are movably disposed on the outer casing 1, with flexible positions. The second and third ends of the rotating assembly 440 respectively rotatably engage with the two second conductive elements 3, while the adjusting member 41 is rotatably disposed on the outer casing 1 and engages with the pushing block 43. The adjusting member 41 is used to adjust the position of the pushing block 43 in the first direction, so that the pushing block 43 has a first moving position and a second moving position in the first direction. In the first moving position, the pushing block 43 drives the two second conductive elements 3 to move closer to each other in the second direction; when the pushing block 43 moves to the second moving position, the pushing block 43 drives the two second conductive elements 3 to move away from each other in the second direction. Therefore, the two second conductive elements 3 have a moving path that moves closer to or further away from each other, thereby adjusting the distance between the second conductive element 3 and the first conductive element 2. If the width of the busbar trough is within the range of the moving adjustment distance of the second conductive element 3, then the adjustable inspection device 100 can adjust the detection width to adapt to busbar troughs of different widths, thereby improving the detection applicability range of the adjustable inspection device 100.

[0039] In other embodiments, the rotating assembly 440 includes a support shaft 44, a first transmission block 45, a second transmission block 47, a first rotating shaft 46, and a second rotating shaft 48. The support shaft 44 is mounted on the push block 43. The first ends of the first transmission block 45 and the second transmission block 47 are both sleeved on the support shaft 44 and rotatably connected to the support shaft 44. The second ends of the first transmission block 45 and the second transmission block 47 are respectively sleeved on the first rotating shaft 46 and the second rotating shaft 48, and the first transmission block 45 is rotatably connected to the first rotating shaft 46, and the second transmission block 47 is rotatably connected to the second rotating shaft 48. The first rotating shaft 46 is mounted on one of the second conductive elements 3, and the second rotating shaft 48 is mounted on the other second conductive element 3.

[0040] Specifically, the first ends of the first transmission block 45 and the second transmission block 47 are rotatably connected to the push block 43 via the support shaft 44. The second end of the first transmission block 45 is rotatably connected to one of the second conductive elements 3 via the first rotating shaft 46. The second end of the second transmission block 47 is rotatably connected to the other second conductive element 3 via the second rotating shaft 48. When the push block 43 moves back and forth in the first direction, the push block 43 will drive one of the second conductive elements 3 to move closer to or away from the first conductive element 2 via the first transmission block 45 and the first rotating shaft 46, and will drive the other second conductive element 3 to move closer to or away from the first conductive element 2 via the second transmission block 47 and the second rotating shaft 48. This further realizes that the two second conductive elements 3 have a moving path that moves closer or further away from each other, thereby satisfying the requirement to detect busbars of different widths.

[0041] Preferably, the second conductive element 3 has a mounting groove 312, at least a portion of the first transmission block 45 and the second transmission block 47 are located within the mounting groove 312, the first rotating shaft 46 and the second rotating shaft 48 are mounted within the mounting groove 312, and the upper and lower ends of the first rotating shaft 46 and the second rotating shaft 48 are connected to the second conductive element 3. Specifically, the mounting groove 312 is formed on the second conductive element 3 so that the second ends of the first transmission block 45 and the second transmission block 47 can be accommodated within the mounting groove 312, and the upper and lower ends of the first rotating shaft 46 and the second rotating shaft 48 can be connected to the second conductive element 3, making the first transmission shaft 46, the second transmission shaft 48, the first transmission block 45, the second transmission block 47 and the second conductive element 3 fit together more compactly.

[0042] Preferably, the angle between the first transmission block 45 and the second transmission block 47 is less than 180 degrees. Specifically, when the pushing block 43 moves back and forth in the first direction, the pushing block 43 causes the first transmission block 45 and the second transmission block 47 to move closer or further apart, thereby adjusting the angle between the first transmission block 45 and the second transmission block 47. Since the angle between the first transmission block 45 and the second transmission block 47 is less than 180 degrees, the direction of movement between the first transmission block 45 and the second transmission block 47 is restricted, further realizing that the two second conductive elements 3 move closer or further apart.

[0043] Preferably, there are two sets of rotating components 440, which are respectively installed at the upper and lower ends of the push block 43. Specifically, when the push block 43 moves, the upper and lower ends of the push block 43 are subjected to uniform force, making the push block 43 more stable when moving; at the same time, it also increases the number of connection points between the push block 43 and the second conductive element 3, thereby increasing the stability of the cooperation between the push block 43 and the second conductive element 3.

[0044] In other embodiments, to ensure that the second conductive element 3 can only move in the second direction, the housing 1 has a first guide groove 112 located at the top and / or bottom of the housing 1, extending along the second direction. The second conductive element 3 has a first guide block 311 that engages with the first guide groove 112. Specifically, the first guide groove 112 on the housing 1 slides in engagement with the first guide block 311 of the second conductive element 3. The first guide groove 112 extends along the second direction and restricts the direction of movement of the first guide block 311. When the second conductive element 3 is driven by the rotating assembly 440, the second conductive element 3 will move along the second direction.

[0045] In other embodiments, the adjusting member 41 includes a knob 411 and a push shaft 42. The knob 411 is fixedly connected to the push shaft 42. The outer wall of the push shaft 42 has an external thread. The push block 43 has an adjusting hole 432 with an internal thread. The push shaft 42 is threadedly connected to the push block 43. The outer wall of the push block 43 has a second guide block 431. The second guide block 431 extends along a first direction. The outer shell 1 has a second guide groove that slides with the second guide block 431.

[0046] Specifically, since one end of the push shaft 42 is fixed to the knob 411, and the other end of the push shaft 42 is threadedly connected to the adjustment hole 432 of the push block 43, and the push block 43 slides in the first direction with the second guide groove of the housing 1 through the second guide block 431, the movement direction of the push block 43 is restricted, and it can only move in the first direction. When the knob 411 is rotated, the push shaft 42 will drive the push block 43 to move back and forth in the first direction, thereby realizing that the push block 43 has a first moving position and a second moving position in the first direction.

[0047] Preferably, a limiting groove 412 is provided between the knob 411 and the push shaft 42. The limiting groove 412 extends circumferentially along the knob 411. The housing 1 has a limiting block 111, which abuts against the side wall of the limiting groove 412. Specifically, the limiting block 111 of the housing 1 is used to cooperate with the limiting groove 412, so that the limiting block 111 abuts against the side wall of the limiting groove 412, restricting the position of the knob 411 and the push shaft 42, preventing the knob 411 and the push shaft 42 from moving in the first direction, and further realizing that the knob 411 and the push shaft 42 drive the push block 43 to move back and forth in the first direction.

[0048] In other embodiments, the second conductive element 3 includes a movable plate 31 and an elastic element 32. The movable plate 31 is rotatably connected to the rotating assembly 440, and the elastic element 32 is mounted on the side wall of the movable plate 31. Specifically, the rotating assembly 440 is used to drive the movable plate 31 to move, while the elastic element 32 is mounted on the inner wall of the movable plate 31. When the second conductive element 3 is inserted into the busbar groove, the elastic element 32 abuts against the inner wall of the busbar groove. The elastic element 32 is squeezed and generates a reaction force on the inner wall of the busbar groove, which improves the stability of the second conductive element 3 in the busbar groove and also improves the stability of the adjustable testing equipment 100 during testing.

[0049] In other embodiments, the outer casing 1 includes a handle 11, a first housing 12, and a second housing 13. The first housing 12 and the second housing 13 are fixedly connected. The handle 11 is mounted on the first housing 12 or the second housing 13. The handle 11 is U-shaped, and the adjusting member 41 is at least partially located within the opening of the handle 11. Specifically, the first housing 12 and the second housing 13 are fixedly connected by a fixing pin 14. After assembly, the first housing 12 and the second housing 13 form a mounting cavity. This mounting cavity is used to accommodate the push block 43 and facilitates installation on the handle 11. The handle 11 is held by the operator, improving the convenience of picking up the adjustable inspection equipment 100. At the same time, the knob 411 of the adjusting member 41 is located within the opening of the handle 11. When the adjustable inspection equipment 100 is inserted into the busbar groove, the knob 411 can be adjusted within the opening of the handle 11.
