Description
Technical field
The invention belongs to Men Lan field, be specifically related to a kind of protective door sill for child lock.
Background technology
Its structure of existing protective door sill is complicated, installs inconvenience, the most stuck, it is accomplished by after local damage all changing, and dismounting trouble, door hurdle locking device as disclosed in Authorization Notice No. CN2823479Y, including a lock, rotating tapered end and a dead bolt, wherein rotation lock headgear is located on this lock, and the top of this rotation tapered end is centrally formed the groove of a longitudinal direction, this hurdle lock uses the mode rotating tapered end, and structure is complicated, dismounting trouble, and be easily damaged, service life is short.
Summary of the invention
In place of it is an object of the invention to for the deficiencies in the prior art, it is provided that a kind of protective door sill lock.
The above-mentioned technical purpose of the present invention has the technical scheme that
A kind of protective door sill lock, including the lock cooperated and buckle structure, described buckle structure includes lock housing, the latch components being arranged at lock housing front end and for controlling the switch block of latch components slide anteroposterior, by linkage part transmission between described latch components and switch block.
As preferably, described latch components includes the pin body inserting lock housing front end and is fixedly arranged on the lock pin of pin body front end, being provided with the pin-and-hole coordinated with lock pin on described lock, described switch block includes inserting lock housing front end and being positioned at the switch sliding shoe above latch components, be fixedly arranged on the button at switch sliding shoe top and for the fastener preventing switch sliding shoe from deviating from from lock housing.
As preferably, described linkage part includes the lock pin brake block being arranged at pin body front top and is arranged at switch sliding shoe front bottom end and is close to the button drive block of described lock pin brake block front surface.
Button is slided backward by button drive block band pendulum lock pin clamp dog when pusher, so that lock pin is moved rearwards by pin-and-hole abjection indentation lock housing, unblanks.
As preferably, described pin body is respectively provided with a back-moving spring with switch sliding shoe rear end.
When the setting of back-moving spring can ensure not apply external force, lock pin stretches out lock housing always and is in locking condition, simultaneously the coordinating of the mutual power of fastener and back-moving spring, and can position switch block with latch components.
Latch components with back-moving spring only first need to be inserted lock housing, then by the switch block mortise lock shell with back-moving spring during installation, and after making fastener be anchored to position, button drive block i.e. keeps off, in lock pin brake block front end, whole latch components played spacing effect.
As preferably, described lock housing front end is provided with pin body chute hole adaptive with pin body and switch sliding shoe respectively and sliding shoe chute hole, and described sliding shoe chute hole top is provided with uncovered button gathering sill.
Button passes button gathering sill, and can unblank along the slip of button gathering sill under external force.
As preferably, described fastener is arranged at bottom described switch sliding shoe rear end, be provided with bottom the squab panel of described sliding shoe chute hole for pass fastener and make fastener be buckled in sliding shoe chute hole base plate rear end face on through hole.
Using simple fastener to carry out coordinating with the base plate rear end face of sliding shoe chute hole thus position each parts, its fastening structure is simple, installation, convenient disassembly.
Can directly be pushed up fastener during dismounting making fastener can extract switch block from lock housing front end after exceeding the base plate rear end face of sliding shoe chute hole.
As preferably, described switch sliding shoe upper rear end is provided with positive stop strip, the squab panel top of described sliding shoe chute hole is provided with the spacing guide through hole for passing positive stop strip, and be positioned at spacing guide through hole rear in lock housing and be arranged at the postive stop baffle coordinated with positive stop strip, the lowermost end of described postive stop baffle exceeds the top of described fastener.
In this height design of postive stop baffle makes lock housing, enough spaces are left in the region gone out by space fastener, are beneficial to when dismantling fastener, will advance row dismounting in stretching into lock housing on fastener.
When button moves to the back-end, positive stop strip is finally against on postive stop baffle thus limits the stroke of each slidable member.
As preferably, the squab panel of described pin body chute hole and sliding shoe chute hole is provided with the spacing block set for being socketed back-moving spring.
Back-moving spring can be positioned by spacing block set, prevents its sideslip in telescopic process.
As preferably, described sliding shoe chute hole base wall panel front end is provided with connection pin body chute hole the transmission gathering sill moved back and forth for linkage part.
As preferably, described lock housing rear end is provided with lock housing installation cavity, is provided with some reinforcements in described lock housing installation cavity.
Lock housing installation cavity is used can be directly buckled on the hurdle frame on a hurdle, easy for installation.
In sum, the method have the advantages that
The present invention is simply plugged into by latch components and switch block that lock housing carries out assembling, snapping is fixed, unblanked by the band pendulum lock pin that slidably reciprocates of switch block again, simple in construction, assembling, convenient disassembly, being difficult to stuck, each parts can arbitrarily be changed, it is simple to maintenance, and each parts are hardly damaged, service life is long.
