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, in particular to an electromagnetic lock initial stage tension compensation device, comprising an electromagnetic lock main body and a casing, a hand-held round rod arranged inside the casing, and an operating mechanism arranged on the surface of the electromagnetic lock main body; Reduce the friction force generated during the use of the electromagnetic lock and improve the sensitivity of the electromagnetic lock during use, which is beneficial to buffer the initial tension exerted by the main body of the electromagnetic lock, and avoid the electromagnetic lock when the friction force is larger than the initial tension of the electromagnetic lock. In the case of failure to work normally, the process of removing the electromagnetic lock body from the interior of the electromagnetic lock frame is convenient, which is beneficial to facilitate maintenance or replacement of the electromagnetic lock body.

technical field [0001] The invention belongs to the technical field of electromagnetic locks, and in particular relates to a device for making up the tension of the initial stage of an electromagnetic lock. Background technique [0002] Electromagnetic locks are widely used in door locks, power bank locks, logistics cabinet locks and other equipment or electronic products, which control the expansion and contraction of the lock tongue 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 is not given for the tension calibration. In some cases where the friction force is larger than the initial tension of the electromagnetic lock, it is necessary to increase the option of the electromagnetic lock, which requires more space, cost and power, and reduces the use effect of the electromagnetic lock. . [0003] To this end, a device for mak...
