Description

Technical Field

[0001] This utility model relates to the field of voltage detection technology, and in particular to a multi-channel voltage detection device. Background Technology

[0002] If you suspect that a metal pipe is carrying voltage, you can use a voltmeter with an appropriate range to measure it. Place the two probes of the voltmeter on the pipe surface and the ground respectively. If there is voltage in the pipe, the voltmeter will display the corresponding value. This method is suitable for detecting whether there is abnormal static electricity or other forms of voltage in the pipe.

[0003] In the prior art, during the use of pipeline voltage detection devices, the gap distance between multiple pipelines is different, and it is not convenient to extend the detection line to different locations, which makes it difficult to perform stable voltage detection on multiple pipelines. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology of pipeline voltage detection devices where the gap distance between multiple pipelines is different, making it inconvenient to extend the detection line to different positions of the channel, which makes it difficult to perform stable voltage detection on multiple pipelines. Therefore, a multi-channel voltage detection device is proposed.

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

[0006] A multi-channel voltage detection device includes a frame, an instrument placed on the inner wall of the frame, a terminal electrically connected to the bottom of the instrument, multiple wires electrically connected to the bottom of the terminal, wire clamps electrically connected to the bottom of the multiple wires, an annular threaded groove formed on the bottom of the instrument, a threaded ring threadedly connected to the inner wall of the annular threaded groove, and a sleeve fixedly connected to the bottom of the threaded ring.

[0007] Preferably, the wire is configured as a spiral.

[0008] Preferably, the inner wall of the frame is provided with a groove, and a fixing rod is fixedly connected to the inner wall of the groove. A clamping plate is movably sleeved on the wall of the fixing rod, and a slot is provided on the bottom side wall of the detector. The clamping plate is clamped and set in the inner wall of the slot.

[0009] Preferably, a torsion spring is movably sleeved on the wall of the fixed rod, one end of the torsion spring is fixedly connected to the inner wall of the card plate, and the other end of the torsion spring is fixedly connected to the inner wall of the frame.

[0010] Preferably, the detector is fixedly connected to a rubber anti-slip pad on the inner wall of the slot, and the card plate is pressed against the inner wall of the rubber anti-slip pad.

[0011] Preferably, a pull rope is fixedly connected to the side wall of the card plate, and the end of the pull rope away from the card plate extends to the outside of the frame and is fixedly connected to a pull ring.

[0012] Compared with the prior art, this utility model provides a multi-channel voltage detection device, which has the following advantages:

[0013] 1. This multi-channel voltage detection device allows the threaded ring to rotate along the inside of the annular thread groove by rotating the sleeve. This sleeve can be used for installation, protecting the wires and clamps. The frame and detector can be placed in a designated position, and the wires are designed in a spiral shape for easy extension. The clamps can be clamped in a designated position for easy subsequent testing and to ensure the stability of voltage detection.

[0014] 2. This multi-channel voltage detection device, by using a torsion spring to push the card plate to extend into the card slot, can improve the stability of the detector connection on the frame and ensure stable use.

[0015] 3. This multi-channel voltage detection device can improve the protection effect and enhance the stability of the clamping plate in the slot by using rubber anti-slip pads. Pulling the pull ring can move the pull rope, making it easy to retract the clamping plate into the groove and facilitating the removal of the detector for maintenance. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 A multi-channel voltage detection device includes a frame 1, a detector 2 placed on the inner wall of the frame 1, a terminal 3 electrically connected to the bottom of the detector 2, multiple wires 4 electrically connected to the bottom of the terminal 3, wire clamps 5 electrically connected to the bottom of the multiple wires 4, an annular threaded groove opened at the bottom of the detector 2, a threaded ring 7 threadedly connected to the inner wall of the annular threaded groove, a sleeve 6 fixedly connected to the bottom of the threaded ring 7, and the wires 4 are arranged in a spiral shape.

[0023] The inner wall of the frame 1 has a groove. A fixing rod 8 is fixedly connected to the inner wall of the groove. A clamping plate 9 is movably sleeved on the rod wall of the fixing rod 8. A slot is opened on the bottom side wall of the detector 2. The clamping plate 9 is clamped and set in the inner wall of the slot. A torsion spring 11 is movably sleeved on the rod wall of the fixing rod 8. One end of the torsion spring 11 is fixedly connected to the inner wall of the clamping plate 9, and the other end of the torsion spring 11 is fixedly connected to the inner wall of the frame 1.

[0024] In use, by rotating the sleeve 6, the threaded ring 7 can be rotated along the inside of the annular thread groove to install the sleeve 6. This can protect the wire 4 and the wire clamp 5. The frame 1 and the detector 2 are placed in the designated position. The wire 4 is set in a spiral shape for easy extension. The wire clamp 5 can be clamped in the designated position for easy subsequent testing and to ensure the stability of voltage detection.

[0025] The torsion spring 11 pushes the card plate 9 to extend into the card slot, which can improve the stability of the connection of the detector 2 on the frame 1 and ensure stable use.

[0026] To facilitate the retraction of the card plate 9 into the recess, such as Figure 1-4 As shown, the detector 2 is fixedly connected to the inner wall of the slot with a rubber anti-slip pad 10, and the card plate 9 is pressed against the inner wall of the rubber anti-slip pad 10. A pull rope 12 is fixedly connected to the side wall of the card plate 9, and the end of the pull rope 12 away from the card plate 9 extends to the outside of the frame 1 and is fixedly connected to a pull ring 13.

[0027] The rubber anti-slip pad 10 can improve the protective effect and enhance the stability of the clamping plate 9 inside the groove. Pulling the pull ring 13 can then pull the pull rope 12 to move, making it easier to retract the clamping plate 9 into the groove and to facilitate the removal and maintenance of the detector 2.
