Problems solved by technology
[0002] Electromagnetic locks are widely used in some equipment or electronic products such as door locks, power bank locks, logistics cabinet locks, etc., which control the expansion and contraction of the deadbolt through electrical signals; however, the working tension of the electromagnetic lock reaches the maximum in the middle and rear sections, and the initial tension It is small, and the initial value of the pull force calibration is not given. In some cases where the friction force is larger than the initial pull force of the electromagnetic lock, it is necessary to increase the options of the electromagnetic lock, which requires more space, cost and power, and reduces the use effect of the electromagnetic lock.

The invention belongs to the technical field of electromagnetic locks, and particularly relates to an electromagnetic lock initial section tension compensation device which comprises an electromagnetic lock body, a shell, a handheld round rod arranged in the shell and an operating mechanism arranged on the surface of the electromagnetic lock body. The friction force generated in the using process of the electromagnetic lock is reduced, the sensitivity of the electromagnetic lock in the using process is improved, the initial tension applied to the electromagnetic lock body is buffered, and the phenomenon that the electromagnetic lock cannot work normally under the condition that the friction force is larger than the initial tension of the electromagnetic lock is avoided; and the process of taking down the electromagnetic lock main body from the interior of the electromagnetic lock frame is relatively convenient, so that the electromagnetic lock main body can be conveniently maintained or replaced.

Background technique [0002] Electromagnetic locks are widely used in some equipment or electronic products such as door locks, power bank locks, logistics cabinet locks, etc., which control the expansion and contraction of the deadbolt through electrical signals; however, the working tension of the electromagnetic lock reaches the maximum in the middle and rear sections, and the initial tension It is small, and the initial value of the pull force calibration is not given. In some cases where the friction force is larger than the initial pull force of the electromagnetic lock, it is necessary to increase the options of the electromagnetic lock, which requires more space, cost and power, and reduces the use effect of the electromagnetic lock. . [0003] For this reason, an electromagnet...
