Description
Technical field
This utility model relates to acoustics and machinery manufacturing technology field, is specifically related to a kind of sound insulation door lock.
Background technology
At present when building acoustic laboratory or sound insulating house and sound proof box, soundproof door will be installed.In order to
Guarantee the sealing between soundproof door and doorframe, sound insulation door lock all can be installed on door.But current every
Glottis lock generally uses some hold down gags, and this just cannot guarantee for large-scale soundproof door
Compress completely in the whole short transverse of door.
Utility model content
The purpose of this utility model is to provide a kind of sound insulation door lock, uses 3 pressing squares
Formula, it is ensured that can compress completely in the short transverse of door, by changing the length of connecting rod,
The position of pressure point can be changed easily.
To this end, this utility model offer techniques below scheme:
A kind of sound insulation door lock, including actively handle assembly, lock core, driven handle assembly,
Connecting rod, rocking arm, base and bearing, described active handle assembly is arranged on the interposition of door
Putting, described driven handle assembly is arranged on an other side and described active handle assembly phase
Corresponding position, described active handle assembly drives driven handle assembly to rotate by lock core,
Driven handle assembly is rotated by connecting rod band motion rocker arm, and one end is connected with connecting rod, separately
One end is connected with base mounted on a door, and rocking arm and driven handle assembly are fixed with rotation
Turning pressure head, rotary press head compresses under the drive of rocking arm and driven handle assembly and is arranged on door
On bearing on frame or two-door another Yishanmen.
The surface that described bearing contacts with rotary press head is to incline along the direction of rotation of rotary press head
Inclined-plane obliquely.
The two ends of described connecting rod and centre are provided with hole, described driven handle assembly and described shake
Arm is provided with pin, and the pin on driven handle assembly is arranged on the centre of described connecting rod
In hole, the pin on rocking arm is arranged in the hole at described connecting rod two ends.
This utility model active handle and driven handle all can be independent unlatching sound insulation
Door.Additionally, this utility model compresses three bearings realizations by arranging three rotary press heads
The sealing of opposite house, and by connecting rod three rotary press heads are coupled together and achieve linkage,
So, this utility model can push down 3 points, the setting on the inclined-plane on bearing on soundproof door
More ensure that door is compacted, make the sealing of door reach optimum state, for large-scale soundproof door
For, advantage of the present utility model is especially apparent.
Accompanying drawing explanation
Fig. 1 is the structural representation (front) of this utility model sound insulation door lock.
Fig. 2 is the structural representation (side) of this utility model sound insulation door lock.
Fig. 3 is the structural representation of the rocking arm in this utility model.
Detailed description of the invention
In order to make those skilled in the art be better understood from the scheme of this utility model embodiment, below
This utility model is described further by Structure Figure and detailed description of the invention.
As shown in Figure 1,2 and 3, sound insulation door lock of the present utility model, including actively handle assembly
10, lock core 20, driven handle assembly 30, connecting rod 40, Rocker arm 50, base 60 and
Seat 70, actively handle assembly 10 is arranged on the centre position of door, driven handle assembly 30
Being arranged on the position that an other side is corresponding with actively handle assembly 10, actively handle is total
10 are become to drive driven handle assembly 30 to rotate by lock core 20, driven handle assembly 30
Driving Rocker arm 50 to rotate by connecting rod 40, Rocker arm 50 one end is connected with connecting rod 40, separately
One end is connected with base 60 mounted on a door, on Rocker arm 50 and driven handle assembly 30
It is respectively fixed with rotary press head 501 and rotary press head 301, rotary press head 501 and rotation pressure
301 compress under the drive of Rocker arm 50 and driven handle assembly 30 be arranged on doorframe or
On the two-door bearing 70 on another Yishanmen.Rotary press head 501 and rotary press head 301
Special construction convenient door lock positions under locking.Its characteristic rotated and special moulding subtract
Little friction and normal switching-off.
The surface that bearing 70 contacts with rotary press head 501 or rotary press head 301 is for along rotating
The inclined-plane that the direction of rotation of pressure head tilts upward.
The two ends of connecting rod 40 and centre are provided with hole, on driven handle assembly 30 and Rocker arm 50
Being provided with pin 302 and pin 502, the pin 302 on driven handle assembly 30 is arranged on
In the hole of the centre of connecting rod 40, the pin 502 on Rocker arm 50 is arranged on connecting rod 40 two ends
Hole in.
Of the present utility model ultimate principle, principal character and of the present utility model have more than been shown and described
Advantage.Skilled person will appreciate that of the industry, this utility model is not restricted to the described embodiments,
