Technical Field

[0001] The utility model relates to the field of weak current line detection, in particular to a visual weak current line safety detection device. Background Art

[0002] Weak current lines are wires or cables used to transmit low-voltage, low-power signals. These lines are typically used for low-voltage systems within buildings, such as home entertainment systems, telephone communication systems, computer network systems, and security monitoring systems. Weak current lines can age over time, necessitating safety testing.

[0003] Existing weak-current line safety detection devices usually clamp and fix the weak-current line to be tested, and then detect the line's surface damage or other safety performance. However, when the weak-current line is clamped and fixed, the weak-current line may bend or wrinkle, affecting the accuracy of the safety detection results, which is relatively inconvenient.

[0004] Therefore, a visual weak current line safety detection device is now developed, which can straighten the weak current line to be detected before the weak current line is detected, thereby improving the accuracy of the detection structure. Utility Model Content

[0006] The technical solution of the utility model is: a visual weak-current line safety detection device, including a base, a bidirectional screw rod, a movable bracket, a motor, a clamp and a stretching clamping mechanism, the right part of the base is rotatably connected to the bidirectional screw rod, the right rear side of the base is connected to the motor, the motor is connected to the bidirectional screw rod, the motor is threadedly connected to the movable bracket, the left and right parts of the movable bracket are connected to the clamp, and the front and rear parts of the base are provided with two left and right stretching clamping mechanisms that can clamp the wires.

[0007] In one embodiment, the clamp is an adjustable arc-shaped piece.

[0008] In one embodiment, the stretching clamping mechanism includes a stretching clamping seat, a stretching rod, a telescoping device, a clamping plate and a fixer. The front and rear parts of the base are connected to the left and right stretching clamping seats, the left and right parts of the stretching clamping seat are connected to the telescoping device, the clamping plates are connected between adjacent telescoping devices, the left and right parts of the clamping plates are connected to the stretching rod, and the ends of the stretching clamping seats close to each other are connected to the fixer.

[0009] In one embodiment, the fixator is a retractable arc-shaped ring.

The upper left side of the base is rotatably connected to the rotating shaft, and the rotating shaft is connected to the glass window.

[0011] In one embodiment, a handle is further included, and the handle is connected to the upper side of the right portion of the glass window.

[0012] After the weak-current line is clamped and fixed, the utility model can stretch the stretching rod to both sides, drive the clamping plate to move, and make the telescopic device shrink, thereby straightening the weak-current line, achieving the effect of being able to straighten the weak-current line to be tested before testing the weak-current line, thereby improving the accuracy of the detection structure.

DETAILED DESCRIPTION

[0018] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0019] A visual weak current line safety detection device, such as Figure 1 and Figure 2As shown, it includes a base 1, a bidirectional screw rod 2, a movable bracket 3, a motor 4, a clamp 5 and a stretching clamping mechanism 6. The right part of the base 1 is rotatably connected to the bidirectional screw rod 2, and the rear side of the right part of the base 1 is connected to the motor 4. The motor 4 is connected to the bidirectional screw rod 2, and the movable bracket 3 is threadedly connected to the motor 4. The left and right parts of the movable bracket 3 are both connected to the clamp 5, and the clamp 5 is an adjustable arc-shaped piece. The front and back parts of the base 1 are both provided with left and right stretching clamping mechanisms 6.

[0020] like Figure 1 and Figure 3 As shown, the stretching clamping mechanism 6 includes a stretching clamping seat 61, a stretching rod 62, a telescoping device 63, a clamping plate 64 and a fixer 65. The front and rear parts of the base 1 are connected to the left and right stretching clamping seats 61. The left and right parts of the stretching clamping seat 61 are connected to the telescoping device 63. The clamping plates 64 are connected between adjacent telescoping devices 63. The left and right parts of the clamping plates 64 are connected to the stretching rod 62. The ends of the stretching clamping seats 61 that are close to each other are connected to the fixer 65. The fixer 65 is a retractable arc ring that can clamp lines of different sizes.

[0021] like Figure 1 and Figure 4 As shown, it also includes a visualization mechanism 7, which includes a rotating shaft 72, a glass window 73 and a handle 74. Ventilation holes 71 are opened on both the front and rear sides of the base 1. The upper left side of the base 1 is rotatably connected to the rotating shaft 72, the rotating shaft 72 is connected to the glass window 73, and the upper right side of the glass window 73 is connected to the handle 74.

[0022] When using the present invention, first move the base 1 to the safe detection area of ​​the weak current line, then pass the line to be detected through the base 1 and the stretching clamping seat 61, and clamp the weak current line through the clamp 5, and at the same time stretch the fixer 65 to fix the two ends of the line to be tested. The fixer 65 and the clamp 5 can be adjusted to adapt to the clamping and fixing of weak current lines of different sizes. After the weak current line is clamped and fixed, the stretching rod 62 can be stretched to both sides to drive the clamping plate 64 to move, so that the telescopic device 63 is contracted, thereby straightening the weak current line, which is convenient for detecting the weak current line. After the weak current line is straightened, the motor 4 is started again to rotate the bidirectional screw rod 2, and then under the action of the thread, the movable bracket 3 is moved forward. After the reciprocating movement, the clamp 5 is driven to move back and forth to rub the weak current line, thereby testing the safety performance of the weak current line, and then playing a role in straightening the weak current line to be tested before the weak current line is tested, thereby improving the accuracy of the detection structure. During the detection of the weak current line, the rotating shaft 72 can be rotated on the base 1 to rotate the glass window 73 to close with the base 1, so that the detection area can be protected and the safety of the detection can be improved. Since the glass window 73 is made of transparent material, the detection area can be observed, which is convenient for controlling the detection process. The handle 74 can be used to open and close the glass window 73, and the vent 71 can ventilate the inside of the base 1 to avoid excessive temperature in the detection area.

Any matters not fully described in the present invention are prior art known to those skilled in the art.
