[0017] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0018] like Figures 1-4 As shown, a magnetic terminal block wiring ruler includes a ruler body 1, which is a wiring ruler based on existing mature technology. The ruler body is provided with measuring scales, and a quick adsorption mechanism 2 is provided on the outer side of the ruler body 1.

[0019] The quick adsorption mechanism 2 includes a support frame 201, with a movable clamping block 202 slidably connected inside the support frame 201. A support 3 is fixedly connected to the back of the support frame 201, and a tie rod 4 is fixedly connected to the inner wall of the support 3. By setting the tie rod 4, a rotation base surface can be provided for the suspension structure of the support 3. Thus, the support 3 and the tie rod 4 can work together with the suspension structure to suspend the support frame 201 and the assembled ruler 1, thereby increasing the placement options for the ruler 1.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, a metal threaded ring 206 and two magnetic blocks 207 are fixedly connected to the inner wall of the support frame 201. The inner wall of the metal threaded ring 206 has a high coefficient of friction. The magnetic blocks 207 have strong magnetic attraction. A lifting ring 5 is provided inside the support 3, and the inner wall of the lifting ring 5 is rotatably connected to the outer surface of the pull rod 4. By providing the lifting ring 5, it can rotate around the outer surface of the pull rod 4 inside the support 3. After the lifting ring 5 is supported by the external hook-shaped or nail-shaped structure, the support frame 201 and the assembled ruler 1 can be suspended, thereby increasing the placement options for the ruler 1.

[0021] An auxiliary bearing 203 is fixedly connected to the inner wall of the movable clamping block 202. Limiting slide pins 6 are fixedly connected to both sides of the movable clamping block 202. The outer surface of each limiting slide pin 6 is slidably connected to the inside of the support frame 201. By setting the limiting slide pins 6, it can slide vertically and directionally inside the support frame 201.

[0022] The inner wall of the metal threaded ring 206 is threaded with a screw 204. The screw 204 and the metal threaded ring 206 have a large damping effect, so that they are not easy to loosen. The inner bottom wall of the support frame 201 is fixedly connected with a first elastic anti-slip pad 8. The upper surface of the first elastic anti-slip pad 8 is in contact with the bottom surface of the ruler 1. By setting the first elastic anti-slip pad 8, the anti-slip property of the inner bottom wall of the support frame 201 can be increased, and it has a certain elasticity, thereby increasing the stability of the ruler 1 being clamped and fixed.

[0023] The outer surface of the screw 204 is fixedly connected to the inner ring of the auxiliary bearing 203, and the bottom surface of the movable clamping block 202 is fixedly connected to a second elastic anti-slip pad 7, the bottom surface of the second elastic anti-slip pad 7 being in contact with the upper surface of the ruler body 1. By setting the second elastic anti-slip pad 7, the anti-slip properties of the bottom surface of the movable clamping block 202 can be increased, thereby increasing the stability of the ruler body 1 being clamped and fixed.

[0024] A hand-tightening disc 205 is fixedly connected to the top of the screw 204. An anti-slip sleeve 9 is fixedly connected to the outer surface of the hand-tightening disc 205. Multiple anti-slip protrusions 10 are fixedly connected to the outer surface of the anti-slip sleeve 9. The anti-slip protrusions 10 can increase the anti-slip properties of the outer surface of the anti-slip sleeve 9.

[0025] Working principle: First, insert the ruler 1 into the support frame 201 so that the bottom surface of the ruler 1 contacts the middle part of the first elastic anti-slip pad 8. Then, turn the hand crank 205 to drive the screw 204 to rotate along the inner wall of the metal threaded ring 206. Under the action of the auxiliary bearing 203, the rotation of the screw 204 is converted into the up and down movement of the movable clamping block 202 until the second elastic anti-slip pad 7 is tightly attached to the upper surface of the ruler 1, thus completing the clamping and fixing of the ruler 1. The limiting slide 6 slides in the support frame 201 to ensure the stable movement of the movable clamping block 202.

[0026] After fixing, the magnetic block 207 inside the support frame 201 can be attracted to the metal cabinet next to the terminal block, realizing the quick positioning of the ruler 1. The ruler 1 can be kept stable without being held by hand. The staff can directly measure the wiring through the scale on the ruler 1, reducing the cumbersome operation of taking and placing tools.

[0027] If the position of the magnetic block 207 relative to the ruler 1 needs to be adjusted, the ruler can be moved directly. The magnetic block 207 will re-attach and fix itself as the position changes. After use, turn the hand crank 205 in the opposite direction, and the movable clamp 202 will rise and release the ruler 1, so that the ruler 1 can be removed. In addition, the ruler can be suspended on the pull rod 4 by the hanging ring 5, which increases the placement of the ruler 1 and further improves the flexibility of use.

[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
