Description
Technical field
The utility model belongs to Smart Home technical field, is related to a kind of drag-line door absorber.
Background technique
Door-inhale is a kind of device for positioning door or window etc., to prevent from wind or touch to cause door uncontrolled
System ground open and close causes to hit and issue the huge sound.In the prior art, door-inhale is divided into permanent magnetism door-inhale and two kinds of electromagnetism door-inhale,
Permanent magnetism door-inhale is commonly used in common door, can only be manually controlled；Electromagnetic door is smoked in the automatically controlled door window device such as fire resistant doorsets, has hand concurrently
Dynamic control and automatic control function.Existing permanent magnetism door-inhale structure is simple, but using effect is poor, and door is opened to by door
It inhales the impact force during positioning and is unable to get buffering；And the door attraction device mechanical structure of Electromagnetic Control is complex, maintenance
Inconvenience is not suitable in family.
There is a disadvantage in above-mentioned door absorber structure, that is, and when opening the door firmly larger, shock sound is larger,
Impact force can not buffer, and cause door absorber damage or door body damage.
Utility model content
The purpose of this utility model is aiming at the above problems existing in the prior art, to provide a kind of drag-line door absorber,
Technical problem to be solved in the utility model is noise when how to eliminate enabling, and a self-return can be made to opening completely
The state opened.
The purpose of this utility model can be realized by the following technical scheme: a kind of drag-line door absorber, which is characterized in that
This door absorber includes fixed block and mounting blocks, and the fixed block is fixed at the outer ledge of door-plate upper end, and the mounting blocks are solid
It is scheduled on and on the wall of fixed block corresponding position, there is an installation cavity in the mounting blocks, be rotatably connected to one in the installation cavity
Rolling wheel, the rolling wheel are rotatedly connected by a shaft with mounting blocks, are connected between the shaft and mounting blocks by clockwork spring, described
Retracting has drawstring on rolling wheel, and one end and the rolling wheel of the drawstring are fixedly linked, the other end and fixed block stationary phase of the drawstring
Even.
Door absorber is arranged in the edge of the upper end of door-plate, avoiding drawstring, inside human body can contact accounting for for space on the door
With to prevent drawstring impeding and hinder to people or object.
Clockwork driven rolling wheel is adopted, can have larger pulling force, and the distance between mounting blocks and fixed block to drawstring
Closer, pulling force is smaller, to enable door to automatically turn in the state of being not completely turned off, and when being opened into extreme position
It will not cause biggish noise.
There is an opening, the opening rotation connection in a kind of above-mentioned drag-line door absorber, on the installation cavity
There are directive wheel one and directive wheel two, the directive wheel one and directive wheel two are on same longitudinal straight line, outside the fixed block
Side is fixedly installed a bolt, and the end of the drawstring and bolt is fixedly linked, and the bolt can be plugged in one He of directive wheel
In gap between directive wheel two.
In a kind of above-mentioned drag-line door absorber, guide groove is all had on the directive wheel one and directive wheel two, it is described to lead
It is that rubber material is made to wheel one and directive wheel two.
Drawstring is oriented to using directive wheel one and directive wheel two, avoids dislocation or sideslip in drawstring use process, and
And directive wheel one and directive wheel two can buffer bolt, enable bolt insertion directive wheel one and directive wheel two it
Between gap when carry out damping noise-reducing, noise is smaller when contacting fixed block and mounting blocks.
Directive wheel one and directive wheel two are universal wheel.
Detailed description of the invention
Fig. 1 is the overall structure diagram of this door absorber structure.
In figure, 1, fixed block；2, mounting blocks；21, installation cavity；31, rolling wheel；32, shaft；4, drawstring；51, directive wheel one；
52, directive wheel two；6, bolt.
Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As shown in Figure 1, this door absorber includes fixed block 1 and mounting blocks 2, fixed block 1 is fixed on the outer side edges of door-plate upper end
At edge, mounting blocks 2 are fixed on and on the wall of 1 corresponding position of fixed block, have an installation cavity 21 in mounting blocks 2, in installation cavity 21
It is rotatably connected to a rolling wheel 31, rolling wheel 31 is rotatedly connected by a shaft 32 with mounting blocks 2, is led between shaft 32 and mounting blocks 2
Clockwork spring connection is crossed, retracting has drawstring 4 on runner, and one end and the rolling wheel 31 of drawstring 4 are fixedly linked, the other end of drawstring 4 and fixation
Block 1 is fixedly linked.
Door absorber is arranged in the edge of the upper end of door-plate, avoiding drawstring 4, inside human body can contact accounting for for space on the door
With to prevent the impeding and hinder to people or object of drawstring 4.
Clockwork driven rolling wheel 31 is adopted, there can be larger pulling force to drawstring 4, and between mounting blocks 2 and fixed block 1
Distance is closer, and pulling force is smaller, so that door be enable to automatically turn in the state of being not completely turned off, and is being opened into limit position
Biggish noise will not be caused when setting.
There is an opening, opening is rotatably connected to directive wheel 1 and directive wheel 2 52, directive wheel one on installation cavity 21
51 and directive wheel 2 52 be on same longitudinal straight line, the outside of fixed block 1 is fixedly installed a bolt 6, drawstring 4 and bolt 6
End be fixedly linked, bolt 6 can be plugged in the gap between directive wheel 1 and directive wheel 2 52.
Guide groove is all had on directive wheel 1 and directive wheel 2 52, directive wheel 1 and directive wheel 2 52 are rubber material
It is made.It is oriented to using 2 52 pairs of drawstrings 4 of directive wheel 1 and directive wheel, avoids misplacing or running in 4 use process of drawstring
Partially, moreover, directive wheel 1 and directive wheel 2 52 can buffer bolt 6, enable bolt 6 in insertion directive wheel 1
Damping noise-reducing is carried out when gap between directive wheel 2 52, noise is smaller when contacting fixed block 1 and mounting blocks 2.
Directive wheel one and directive wheel two are universal wheel.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
Belonging to those skilled in the art can make various modifications or additions to the described embodiments or using similar
