Detailed description of the invention
Referring to figs. 1 through Fig. 5, a kind of latch lock that can be used for the front maintenance of LED screen of the present utility model, described latch lock comprises lock body 1 and installing rack 2, described lock body 1 is installed on module 100, it comprises fixed head 11, rotating shaft 12 and nut sleeve 13, described fixed head 11 is sleeved in rotating shaft 12, rotating shaft 12 upper end is provided with the dead bolt 120 that can stop that fixed head 11 is deviate from, rotating shaft 12 lower end is provided with stud 121, conveniently produce and install, described dead bolt 120 is for being installed on the pin rod of rotating shaft 12 end, described stud 121 is one-body molded with rotating shaft 12, during installation, rotating shaft 12 upper end is passed fixed head 11, then pin rod is installed in the pin-and-hole of dead bolt 120 upper end.Be provided with between described stud 121 and fixed head 11 and be enclosed within rotating shaft 12 for ordering about the spring 14 that rotating shaft 12 moves downward, described stud 121 is threaded with nut sleeve 13, stud 121 bottom is provided with is convenient to insertion tool 200 with the blind hole 122 of rotating shaft 12, and the corresponding blind hole 122 of nut sleeve 13 is provided with is convenient to insertion tool 200 with the through hole 131 of rotating nut cover 13; Described installing rack 2 is installed on the steel work of ceiling, which is provided with journal stirrup 21, journal stirrup 21 is provided with and interts for dead bolt 120 and can form the lockhole 211 of cross fastening structure with dead bolt 120, and the upper surface of described journal stirrup 21 is provided with and can stops when nut sleeve 13 rotates that dead bolt 120 is to limit the position-limit mechanism 212 of rotating shaft 12 rotation.
When the utility model is installed, on the steel work that installing rack 2 and lock body 1 are arranged on ceiling respectively and module 100, then moving module 100 makes dead bolt 120 aim at lockhole 211 on journal stirrup 21, then insert the blind hole 122 of stud 121 through nut sleeve 13 with instrument 200, up promote rotating shaft 12, make dead bolt 120 through lockhole 211, then the position of stud 121 to dead bolt 120 and the effect of position-limit mechanism 212 phase is rotated, then loose one's grip downwards, dead bolt 120 can abut with journal stirrup 21 under action from the spring 14 and match with position-limit mechanism 212, now, instrument 200 is deviate from stud 121 downwards but does not depart from nut sleeve 13, namely nut sleeve 13 is turned clockwise near fixed head 11 direction, because spring 14 pairs of studs 121 produce downward pressure on top surface, can not move up at the process shaft 12 turning nut sleeve 13, ensure dead bolt 120 all the time with the effect of position-limit mechanism 212 phase, simultaneously due to the stop of position-limit mechanism 212 pairs of dead bolts 120, nut sleeve 13 can be moved upward by stud 121 relatively, thus dead bolt 120 can be locked on installing rack 2.Contrary operation during dismounting.
It should be noted that, before up promoting rotating shaft 12, must ensure that the distance between nut sleeve 13 and dead bolt 120 is enough to make dead bolt 120 pass lockhole 211, if when above-mentioned distance is not enough, instrument 200 can be utilized to insert the through hole 131 of nut sleeve 13, rotating nut cover 13, makes nut sleeve 13 move downward relative to stud 121, to increase above-mentioned distance.Preferably, described nut sleeve 13 upper end is fixed with for stopping the nut cap 15 that stud 121 is deviate from, and described nut cap 15 is provided with the mesopore 151 be convenient to spring 14 and passed.Particularly, the diameter of described mesopore 151 is less than the diameter of stud 121 to stop that stud 121 deviates from nut sleeve 13, and the diameter of mesopore 151 is greater than the external diameter of spring 14 to avoid hindering the flexible of spring 14 simultaneously.Described nut cap 15 can avoid constructor to cause because holding the moving down distance of bad nut sleeve 13 situation that nut sleeve 13 comes off from stud 121 when installing or dismantle latch lock, is convenient for people to dismounting.
Further, described blind hole 122, through hole 131 are hexagon ring, use die nut to coordinate with hexagon ring and can carry out dismounting to latch lock, without the need to using other instruments 200, easy accessibility, simultaneously has six contact surfaces between hexagon ring and die nut, stressed fully and be not easy to damage.Especially, when blind hole 122 and through hole 131 measure-alike, because die nut needs to contact with blind hole 122 through after through hole 131, and in the process turning nut sleeve 13, the through hole 131 in nut sleeve 13 can be caused inconsistent with blind hole 122 position, at this, the setting of hexagon ring, convenient construction personnel find through hole 131 position corresponding with blind hole 122 fast accurately.
Further, described position-limit mechanism 212 is for being arranged on the stopper slot matched with dead bolt 120 of journal stirrup 21 upper surface.Described stopper slot is easy to process, saves material, even if having slight deviation when dead bolt 120 is at spring 14 falls downward with stopper slot position, also automatically landing in stopper slot, can have zero offset capability.Certainly, described position-limit mechanism 212 also can adopt the limited block being arranged on journal stirrup 21 upper surface to replace.The conveniently anglec of rotation of constructor's perception stud 121, constructor is avoided to rotate the angle of stud 121 excessive or too small and cause dead bolt 120 cannot fall into stopper slot, described stopper slot and lockhole 211 perpendicular, dead bolt 120 can rotate to stopper slot top position through stud 121 being rotated 90 ° after lockhole 211 by dead bolt 120, easy to operate.
Further, the utility model also comprises and being arranged on module 100 and the module corner brace 3 be fixedly connected with fixed head 11, the corresponding lockhole 211 of module corner brace 3 be provided be convenient to dead bolt 120 through and the locating hole 31 dead bolt 120 is positioned past on lockhole 211 direction.Described locating hole 31 is consistent with lockhole 211 direction, dead bolt 120 can be positioned past on the direction of lockhole 211, make the fast easier for installation of module 100.Can certainly by module corner brace 3 and fixed head 11 one-body molded, namely the locating slot be positioned past for accommodating dead bolt 120 and by dead bolt 120 on lockhole 211 direction is set in fixed head 11 upper surface.
The utility model also provides a kind of LED display, comprise some modules 100, described module 100 is fixing on the ceiling by above-mentioned latch lock, the corresponding each lock body 1 of module 100 is equipped with the instrument via hole 101 that the instrument of being convenient to 200 penetrates lock body 1, and described instrument via hole 101 can be grating groove on module 100 or keep away a hole.This LED display is operated by insertion tool 200 pairs of latch locks in the instrument via hole 101 before module 100, and safeguard dismounting before can realizing, dismounting is simple and convenient.
All features disclosed in this manual, or the step in disclosed all methods or process, except the feature mutually repelled and/or step, all can combine by any way, unless specifically stated otherwise, all can be replaced by other equivalences or the alternative features with similar object, namely, unless specifically stated otherwise, each feature is an embodiment in a series of equivalence or similar characteristics.
