Abstract
The invention discloses an opening and closing limiting mechanism in an indoor electromagnetic lock. The opening and closing limiting mechanism comprises a shell cover and a switch handle. The switch handle is rotationally connected to the shell cover. An unlocking hole is formed in the outer surface of the shell cover. A limiting table is arranged on the inner surface of the shell cover and provided with a key stirring groove communicating with the unlocking hole. The switch handle comprises a rotating body, a connecting piece, a stop ring and a driving lever. The rotating body is rotationally connected to the shell cover, and one end of the rotating body penetrates the shell cover and is connected with the connecting piece. The stop ring is arranged on the rotating body in a sleeving manner, and the connecting piece is axially positioned on the rotating body. The driving lever is fixedly connected to the connecting piece, and the connecting piece abuts against the limiting table. According to the opening and closing limiting mechanism, the situation that due to the fact that the switch handle is pulled not in the unlocking direction, a lock bolt of the electromagnetic lock is damaged can be effectively prevented, and the service life of the electromagnetic lock can be effectively prolonged.
Description
Technical field:
The present invention relates to the folding position-limit mechanism in a kind of indoor electromagnetic lock.
Background technology:
Existing indoor anti-phase electromagnetic lock includes housing 1 and cap, cap covers on housing 1, the internal structure of housing 1 is as shown in Figure 1, including Electromagnetic lock 12, locking bolt block 13 and locking bolt 14, cap is rotatably connected to rotary spanner, one end of this rotary spanner is plugged on the locking bolt block 13 in housing 1, after Electromagnetic lock 12 power-off, dynamic iron core 11 on Electromagnetic lock 12 departs from locking bolt block 13, then pass through the rotary spanner pulling on cap, locking bolt 14 is moved left and right on housing 1, thus realizing the folding of electromagnetic lock.
After the existing electromagnetic lock dynamic iron core 11 on Electromagnetic lock 12 departs from locking bolt block 13, the locking bolt on electromagnetic lock is mobilizable, therefore rotates rotary spanner and locking bolt can be made to move left and right.When unblanking; operator usually can ignore and are labeled in unblanking direction and arbitrarily pulling rotary spanner on cap, if not by unblanking direction and often pulling rotary spanner, long-time use after; easily damage locking bolt 14, can impact the service life of electromagnetic lock then.
Therefore, necessary prior art improves to solve the deficiency of prior art.
Summary of the invention:
The present invention provides the folding position-limit mechanism in a kind of indoor electromagnetic lock to solve above-mentioned prior art Problems existing.
The technical solution adopted in the present invention has: the folding position-limit mechanism in a kind of indoor electromagnetic lock, including cap and switch knob, described switch knob is rotatably connected on cap, the outer surface of described cap is provided with open keyhole, the inner surface of described cap is provided with limiting stand, and described limiting stand is provided with the key being connected with described open keyhole and stirs groove；
Described switch knob includes rotor, connects sheet, back-up ring and driving lever, described rotor is rotatably connected on cap, and one end is through cap connected with being connected sheet, shield ring sleeve is located on rotor, and make connection sheet axially position on rotor, driving lever is fixedly connected on connection sheet, and described connection sheet is resisted against on limiting stand.
Further, described connection sheet is provided with connecting hole, connects sheet and is connected on rotor by this connecting hole.
Further, the sidewall of described connecting hole is provided with spline platform part.
Further, described rotor is provided with through hole.
Further, described rotor is fixedly connected with rotating handles.
There is advantages that
The present invention can effectively prevent due to not by unblanking direction and the locking bolt of operating switch handle and damaging electromagnetic lock, it is possible to the effective service life increasing electromagnetic lock.
