Description

Technical Field

[0001] This utility model relates to the field of bridge tester technology, specifically a multi-channel bridge tester. Background Technology

[0002] A bridge tester is a precision instrument used to measure the parameters of electrical components such as resistors, inductors, and capacitors. Its working principle is based on the balance condition of the Weisston bridge. It determines the value of an unknown resistor by comparing the current balance between a known resistor and the resistor to be measured. A bridge tester typically includes a precision current source, an accurate voltage measuring device, and a user-friendly control interface. It can perform a variety of electrical tests, including measuring the resistance value of resistors, the inductance value of inductors, and the capacitance value of capacitors.

[0003] A multi-channel, multi-functional bridge tester is disclosed in patent document CN221124656U. The bottom surface of the main body of the multi-channel, multi-functional bridge tester is provided with an adjustment mechanism. The adjustment mechanism can lock or open / close the structure of the adjustment angle by changing the angle of the flip magnetic block, and the opening / closing angle can be controlled by sliding.

[0004] While the above solution can adjust the angle of the main body of the bridge tester, it can only lift the tail of the bridge tester during the adjustment process, allowing the bridge tester to be adjusted in only one direction. This results in a small range of angle adjustment for the main body of the bridge tester. Therefore, a multi-channel bridge tester is needed to solve the above technical problems. Utility Model Content

Detailed Implementation

[0017] The present invention will now be further described with reference to the accompanying drawings.

[0018] like Figures 1 to 6 As shown, a multi-channel bridge tester includes a bridge tester body 10. A guide rail 20 is mounted on the bottom side of the bridge tester body 10, and the guide rail 20 is installed at the middle position of the bottom side of the bridge tester body 10. The length direction of the guide rail 20 is parallel to the width direction of the bridge tester body 10. Two movable frames 30 are slidably connected to the guide rail 20. A fixed support assembly is provided between each movable frame 30 and the guide rail 20 to fix the movable frame 30. The two ends of the two movable frames 30 are... Each storage frame 40 is rotatably connected to the movable frame 30. Each storage frame 40 is provided with a clamping and locking structure 50 between itself and the movable frame 30. The clamping and locking structure 50 is used to fix the storage frame 40 in a suitable position. Each storage frame 40 is slidably connected to a support leg 60. Each support leg 60 is provided with a displacement locking component and a rotation fixing component between itself and the storage frame 40. The displacement locking component is used to fix the support leg 60 in a suitable position on the storage frame 40, and the rotation fixing component is used to fix the support leg 60 at a suitable angle.

[0019] It should be noted that the movable frame 30 is convex in shape. The side of the storage frame 40 away from the bridge tester body 10 is on the same horizontal plane as the side of the movable frame 30 away from the bridge tester body 10. When the bridge tester body 10 is laid flat, the storage frame 40 and the movable frame 30 work together to support the bridge tester body 10, ensuring the stability of the bridge tester body 10 when laid flat.

[0020] like Figure 2 and Figure 5 As shown, the displacement locking component includes a locking threaded rod 61 rotatably connected to the support leg 60 and a locking limiting groove 41 opened on one side of the storage frame 40. The locking limiting groove 41 is connected to the interior of the storage frame 40. The locking threaded rod 61 passes through the interior of the locking limiting groove 41 and is slidably connected to the locking limiting groove 41. A locking nut 62 is threadedly connected to the outer surface of the locking threaded rod 61.

[0021] When the position of the support leg 60 needs to be adjusted, the support leg 60 is moved along the length of the storage frame 40. At this time, the locking thread rod 61 moves accordingly. The support leg 60 is adjusted to a suitable position according to the actual situation during use. Then, the locking nut 62 is rotated to make it fit tightly with the storage frame 40, thereby fixing the support leg 60 in a suitable position.

[0022] It should be noted that the length of the support leg 60 is less than the length of the internal dimensions of the storage frame 40, and the thickness of the support leg 60 is less than the thickness of the storage frame 40, so that the support leg 60 can be completely retracted into the storage frame 40. The locking nut 62 can be a butterfly locking nut, which makes it easy for the operator to manually rotate the locking nut 62 and lock and fix the support leg 60.

[0023] The rotating fastener includes multiple threaded holes 63 on one side of the support leg 60 and a connecting groove 42 on one side of the storage frame 40. The connecting groove 42 is connected to the interior of the storage frame 40. A fixing bolt 64 is threaded onto the inner wall of one of the threaded holes 63 and passes through the interior of the connecting groove 42.

[0024] After adjusting the support leg 60 to a suitable position, rotate the support leg 60 around the center of the locking threaded rod 61. Adjust the support leg 60 to a suitable angle according to the actual situation during use, and align the fixed threaded hole 63 at a suitable position with the position of the connecting groove 42. Then, pass the fixing bolt 64 through the inside of the connecting groove 42 and thread it into the fixed threaded hole 63 to fix the support leg 60 and fix it at a suitable angle. By adjusting the support legs 60 at different positions, the front end of the bridge tester body 10 can be adjusted to face downwards or upwards, allowing for a wide range of adjustment of the bridge tester body 10. All four support legs 60 can be adjusted to a certain angle to support the bridge tester body 10. Figure 1 , Figure 2 and Figure 4 As shown, Figure 1 , Figure 2 and Figure 4 This indicates the different states of the bridge tester body 10, where... Figure 4 The structural diagram shows how to adjust the four support legs to the same angle so that the main body 10 of the bridge tester can be supported, thus preventing the main body 10 of the bridge tester from directly contacting the contact surface.

[0025] It should be noted that the multiple fixed threaded holes 63 are arranged in a circular array about the center of the locking threaded rod 61, and the fixed threaded holes 63 are connected to the connecting groove 42, so that the fixing bolt 64 can pass smoothly through the inside of the connecting groove 42 and be threaded into the fixed threaded hole 63.

[0026] The clamping and locking structure 50 includes a clamping threaded rod 51 fixedly connected to the movable frame 30, a clamping nut 52 threadedly connected to the outer surface of the clamping threaded rod 51, and a rotating plate 53 rotatably connected to the storage frame 40 on the outer surface of the clamping threaded rod 51.

[0027] Rotating the rotating plate 53 adjusts the orientation of the storage frame 40 along its length and position. Rotating the clamping nut 52 ensures a tight fit between the nut and the rotating plate 53, fixing the plate 53 in place and preventing further rotation. This secures the rotating plate 53 and the storage frame 40 in a suitable position. At this point, one side of the bridge tester body 10 can be lifted, tilting the body. A schematic diagram of the bridge tester body 10 in this tilted state is shown below. Figure 3 As shown.

[0028] The fixed support assembly includes multiple fixed insertion holes 21 on the guide rail 20 and a storage hole on one side of the movable frame 30. A fixed threaded rod 31 is threadedly connected to the inner wall of the storage hole. A knob 32 is fixedly connected to one end of the fixed threaded rod 31. The fixed threaded rod 31 is positioned corresponding to the fixed insertion hole 21 and is inserted into the fixed insertion hole 21. A support connector is provided between the guide rail 20 and the movable frame 30. The support connector is used to ensure that the movable frame 30 will not separate from the guide rail 20 during smooth movement.

[0029] The support connector includes a slide groove on one side of the movable frame 30. Support grooves 33 are provided on both sides of the inner wall of the slide groove. The movable frame 30 is slidably connected to the guide rail 20 through the support grooves 33 and the slide groove. A support limiting plate 22 that is fixedly connected to the guide rail 20 is slidably connected to the inner wall of each support groove 33.

[0030] When adjusting the position of the movable frame 30, the movable frame 30 is moved along the direction of the guide rail 20. At this time, the storage frame 40 moves accordingly. Adjust the storage frame 40 to a suitable position according to the actual situation during use. Then, rotate the fixing threaded rod 31 to insert it into the fixed socket 21 in a suitable position to fix the movable frame 30 and fix the storage frame 40 in a suitable position. This allows the support leg 60 located inside the storage frame 40 to better support the bridge tester body 10.

[0031] It should be noted that the width of the knob 32 is smaller than the depth of the receiving hole, and the diameter of the knob 32 is smaller than the diameter of the receiving hole. This facilitates the rotation of the fixed threaded rod 31 by the knob 32 and avoids the knob 32 being exposed outside the receiving hole. This prevents the knob 32 from being exposed to the outside and coming into contact with the working surface of the bridge tester body 10, thus avoiding the bridge tester body 10 from tilting when it is being discharged horizontally, and ensuring that the bridge tester body 10 is discharged horizontally and stably.

[0032] The bridge tester body 10 includes a bridge tester main body 11, which is provided with multiple connection ports 12 and a display screen 13. The bridge tester main body 11 is equipped with various electrical components. Multiple electrical components that need to be tested can be connected through the multiple connection ports 12, so that the bridge tester has multiple test channels and can perform test operations on multiple electrical components at the same time.

[0033] The main body 11 of the bridge tester has several heat dissipation vents 14 on its two symmetrical sides. The heat dissipation vents 14 are used to dissipate heat from the electrical components inside the main body 11 of the bridge tester.
