Description
Technical field
A kind of automatic anti-theft door lock is the utility model is related to, particularly a kind of Jing Yin antitheft door of automatic locking noise abatement of closing the door
Lock silencing apparatus.
Background technology
Some safe-guard door locks have employed the buffer with medium to realize the Jing Yin function of noise reduction in the market, and it is tied
Structure is that buffer is arranged on into latch bolt telescopic direction and acted on locking bolt or locking bolt planker, due to buffer diameter of cylinder and length
The factor of degree, design space is very limited when causing locking bolt and locking bolt planker and realizing the function such as triggering certainly, or with sacrificial
Domestic animal part strength is cost to meet the layout of buffer.In view of the above-mentioned problems, many manufacturers and knowledgeable people are carried out
Exploitation and develop, but there has been no comparatively ideal product so far to emerge.
The content of the invention
In order to overcome above-mentioned deficiency present on existing Automatic anti-theft lock mute function, the purpose of the utility model patent
Be to provide it is a kind of it is simple in construction, rationally distributed, easy to install, that Jing Yin and anticollision effect is good, security performance is excellent is antitheft
Door lock silencing apparatus.
The utility model solve above-mentioned technical problem used by technical scheme, it include lock housing, linkage board, buffer,
Linkage board driving spring, it is characterized in that：Shoulder pivot pin, the first guide pillar and the second guide pillar, described connection are provided with described lock housing
Pin, through hole, bending and spring carrier arm are provided with dynamic plate, described linkage board is set in the first described guide pillar by through hole
On, described linkage board driving spring one end is set on the second described guide pillar, and the other end is set in described spring carrier arm
On.
Further scheme of the present utility model, described buffer include cylinder body, piston rod and are arranged in cylinder body
Buffer medium, buffer medium are liquid or gas.
Further scheme of the present utility model, the cylinder ends, which are set on described shoulder pivot pin and rotated around it, matches somebody with somebody
Close, described piston rod end is set on described pin and rotates around it cooperation, and described bending covers described piston
Boom end is to prevent piston rod from departing from described pin.
After said structure, have the following advantages compared with prior art and effect：First, buffer acts directly on master
It is simple in construction in STATEMENT OF FEDERALLY SPONSORED, it is rationally distributed, the space of lock housing can be made full use of to realize muting function and anti-collision,
The service life of lockset is improved simultaneously；Second, locking bolt, locking bolt planker and realization are unrestricted from the design space of the functions such as triggering
System, it is ensured that the security performance of safe-guard door lock is unaffected；Third, acting in main STATEMENT OF FEDERALLY SPONSORED, each lock point will not be caused
Unbalance stress, the expanding-contracting action of Suo Dian mechanisms is also more smooth consistent, and each lock point no matter is unlocked or blocking, and tapered end position is all
Can be more smooth.
Brief description of the drawings
Fig. 1 is structural representation of the utility model silencing apparatus under unlocking condition.
Fig. 2 is the structural representation of the utility model silencing apparatus in the lockout condition.
Fig. 3 is the utility model silencing apparatus explosive view.
Wherein：08 gangbar driving spring, 09 cylinder body, 10 piston rods, 215 pins, 36 linkage boards, 361 through holes, 362 foldings
It is curved, 363 spring carrier arms, 44 lock housings, 454 first guide pillars, 463 second guide pillars, 47 shoulder pivot pins.
Embodiment
As shown in Figure 1, Figure 2 and Figure 3, it is a kind of specific embodiment of safe-guard door lock silencing apparatus of the utility model, it
Including lock housing 44, linkage board 36, buffer, linkage board driving spring 08, it is characterized in that：Shoulder axle is provided with described lock housing 44
Pin 47, the first guide pillar 454 and the second guide pillar 463, pin 215, through hole 361, the and of bending 362 are provided with described linkage board 36
Spring carrier arm 363, described linkage board 36 are set in by through hole 361 on the first described guide pillar 454, and described linkage board drives
One end of spring 08 of moving is set on the second described guide pillar 463, and the other end is set on described spring carrier arm 363, described
Buffer includes cylinder body 09, piston rod 10 and the buffer medium being arranged in cylinder body 09, and buffer medium is liquid or gas, institute
State the end of cylinder body 09 to be set on described shoulder pivot pin 47 and rotate around it cooperation, the described end of piston rod 10 is set in institute
On the pin 215 stated and rotate around it cooperation.
The course of work of the present utility model is as follows：When latch bolt knocking door case triggering lockable mechanism unblock at closing time, linkage board
The tension force of driving spring 08 is released, and pulls linkage board 36 to rotate clockwise, and the pin 215 on linkage board 36 is then with piston
Bar 10 stretches out, due to the damping action of the buffer medium in the cylinder body 09 of buffer so that the rotation of linkage board 36 becomes slow
It is and steady.And when hand-drive pulling axis is unlocked, when gangbar 36 is rotated counterclockwise by pulling axis driving force, now linkage board drives
Spring 08 of moving gradually is increased by pulling force effect, spring tension, and the piston rod 10 of buffer is by the process in compression and back cylinder body 09
In the damping force very little of medium that is subject to, i.e. the driving force of pulling axis and the tension force collective effect of linkage board driving spring 08 linking
On plate 36 so that the motion of unlocking process internal part also changes relatively gentle.
The damping action of buffer to lock becomes quieter with releasing process, while also extends mechanical lock housing
Service life.
It is described above, simply specific embodiment of the utility model, not the utility model is made any formal
Limitation, on the basis of the technical solution of the utility model is not departed from, made simple modification, equivalent variations or modification, falls
Enter the scope of protection of the utility model.
