Fig. 2 is the left view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing 1, Fig. 2 the utility model is done further description:
The described a kind of shield door electronic lock of the utility model comprises mount pad 4, electromagnet 1, left limit switch 2, right limit switch 13, portable plate 3, stiff spring 7, two dead bolts 9 and two scotchs 6.The shield door electronic lock is mainly used in the assist control of splitting the sliding door switching process in the screen door, guaranteeing the sliding door safe opening and reliably to close, thereby improves safety and the stability that sliding door uses, and prevents that contingency from taking place.
Wherein, electromagnet 1 is fixed on the position near mount pad 4 tops as the promoter of transmission process, and the magnetic core of electromagnet 1 is connected with portable plate 3 tops, through electromagnetic principle can control portable plate 3 at upper and lower to motion.
Left and right limit switch 2,13 is separately fixed on the mount pad 4 of electromagnet 1 both sides, and limit switch is used for the upper and lower extreme position of detected event plate 3, and the process coordinating of guaranteeing to unblank carries out.
For ease of installing and using, portable plate 3 is usually designed to L shaped, and the horizontal end face 5 of L shaped portable plate 3 is towards the inboard, horizontal end face 5 be shaped as ' protruding ' font.On the perpendicular end surface of portable plate 3, be provided with the groove 10 of vertical direction, portable plate 3 flexibly connects through bolt and groove 10 and mount pad 4, also can guarantee when restraint plate 3 moves forward and backward portable plate 3 upper and lowers to mobile.
Two scotchs 6 are placed on the below of the horizontal end face 5 of portable plate with the mode horizontal pendulum of left and right arrangement; Be respectively equipped with the gear teeth on the relative contoured surface of two scotchs 6; The gear teeth are meshing with each other; The engagement gear teeth have guaranteed that sliding door two scotchs 6 in the open and close process can rotate equal angular synchronously, have realized the synchronism of switch door process.Two horizontal scotch 6 the inners are hinged on mount pad 4 bottoms respectively, and can rotate around jointed shaft.Be respectively equipped with the horizontal grab to inner opening on two scotch 6 leading flanks, the grab outside is provided with guiding arc 12, holds convenience, reliable for making grab, and the grab inboard protrudes in jointed shaft.For realizing support to portable plate 3; Also be respectively equipped with the support bar 11 of vertical direction at two scotch 6 rear portions; Two support bars 11 are corresponding to the recess of the horizontal end face of ' protruding ' font 5 both sides; Support bar 11 tops can with the pig of the horizontal end face 5 of portable plate, thereby cooperate the upper and lower motion of portable plate 3, the controllability of accomplishing portable plate 3 supports.
Stiff spring 7 is connected between the support bar 11 of two scotchs 6, from oppositely scotch 6 being drawn, forms the effect of a back-moving spring.
Two dead bolts 9 are separately fixed at left and right two of required control and split the sliding door top, and along with moving of sliding door.It is corresponding with two grabs of scotch 6 respectively that dead bolt 9 is provided with 8, two locking bars 8 of locking bar of vertical direction, through grab to the holding of locking bar 8, auxiliary sliding door safe opening or close.
For further improving the reliability of locking process; On the horizontal end face 5 of L shaped portable plate, also be provided with through hole; Through hole is corresponding with the position of grab, and through-hole diameter is greater than locking bar 8 diameters, after locking bar 8 snaps in grab; The horizontal end face 5 of portable plate 3 is enclosed within on the locking bar 8 through through hole, puts in place to guarantee that locking bar 8 further holds.
In the actual use; At first mount pad 4 is fixed on the sliding door top cross beam; And two dead bolt 9 correspondences are installed in the header that horizontally slips, the perpendicular end surface and the through hole on the horizontal end face 5 that keep locking bar 8 and portable plate 3 on the dead bolt 9 are on same vertical plane; Then, left and right limit switch 2,13 and electromagnet 1 are controlled system connectivity through lead and shield door, make shield door electronic lock and sliding door cooperation each other.When sliding door was in opening, electromagnet 1 did not do work, and portable plate 3 is in free state.Receive 7 pairs of support bars 11 of stiff spring and the inwardly effect of traction of scotch 6; Under the cooperation of the engagement gear teeth; Scotch 6 inwardly rotates along jointed shaft, and grab is in external open configuration, is supported on the horizontal end face 5 times of portable plate 3 after two support bars 11 are drawn close each other; Portable plate 3 can not fall, and whole shield door electronic lock is in opening.When sliding door was closed, locking bar 8 received the guiding of grab outside guiding arc 12, impinged upon the grab inboard after slipping into grab; Because impact is greater than the pulling force of stiff spring 7, simultaneously to inner rotary, grab holds locking bar 8 bottoms around jointed shaft for two scotchs 6 and support bar 11; Two support bars 11 are removed for 5 times from the horizontal end face of portable plate, and portable plate 3 falls, simultaneously; Portable plate 3 triggers left limit switch 2 and sends signal, sends instruction after shield door control system receives signal, sliding door outage and stop motion; When falling, the horizontal end face 5 of portable plate is enclosed within on the locking bar 8 through through hole; Locking bar 8 tops are realized holding, and dead bolt 9 is completely fixed, and left and right sliding door is closed completion.When needs were opened once more, electromagnet 1 at first did work, and carried on the portable plate 3, and portable plate bottom level end face 5 is removed between two support bars 11, and the through hole on the horizontal end face 5 is thrown off from locking bar 8 tops.Receive the effect of stiff spring 7, scotch 6 inwardly rotates, support bar 11 returns, grab unclamps from locking bar 8 bottoms, about two dead bolts 9 be in free state.Along with carrying on the portable plate 3, right limit switch 13 is touched at the portable plate top, and shield door control system after receiving signal control instruction takes place; The sliding door energising, sliding door is opened to both sides, simultaneously; Control electromagnet 1 outage of shield door control system, portable plate 3 freely falls, and receives support bar 11 influence of return; Portable plate 3 is supported on the support bar 11, and sliding door is opened and accomplished.The rest may be inferred, thereby realize the safe opening and pass closed procedure of sliding door.
