Description
Technical field
The present invention relates to roller shutter technical fields, more particularly to a kind of cord retracting device that can be used for automobile interior decoration.
Background technique
Existing cord retracting device is usually the wherein spool by structure compositions such as metal shell, cord, spool, wind springs
It is placed in metal shell, and cord is wound on spool, spool realizes the winding of cord using wind spring, when spool rotates forward
When, cord pulls open, and when needing to recycle cord, spool rotates backward under the action of wind spring, and cord is withdrawn.
However, in existing cord retracting device, since cord is wound on single spool, for stock size
Cord, spool cannot be meticulous, otherwise open and need to rotate when furling cord much circles and its mechanical strength cannot be guaranteed, and
After cord retracting, the diameter dimension after spool is integrally wound also is increased considerably, and adds metal shell, entire retracting device
Occupied space is very big, to the more demanding of arrangement space, is especially difficult to install and use in the small spaces such as automobile.
Summary of the invention
Based on this, the object of the present invention is to provide a kind of cord retracting device, with it is compact-sized, small in size, account for
It is small according to space, the advantages of large scale cord can be stored.
The technical solution adopted by the present invention is as follows：
A kind of cord retracting device, including fixed coiler, mobile coiler, winding bar, cord and two are parallel opposite
Sliding slot；One end of the sliding slot is the end A, and the other end is the end B；
The fixed coiler includes N number of fixed roller, and N is the natural number greater than 1；Each fixed roller is perpendicular to described
Sliding slot, and both ends are fixed；N number of fixed roller is spaced apart between the end B of two sliding slots, and by the end A of sliding slot
To the direction at the end B, N number of fixed roller number consecutively is 1~No. N, and the diameter of 1~N fixed roller increases one by one；
The mobile coiler includes N number of mobile roller bearing, and each mobile roller bearing is perpendicular to the sliding slot, and both ends are pacified respectively
Loaded on can move in two sliding slots and along two sliding slots；N number of mobile roller bearing is spaced apart, and by the end B of sliding slot to the end A
Direction, N number of mobile roller bearing number consecutively are 1~No. N, and the diameter of 1~No. N mobile roller bearing increases one by one；
The winding bar is set between No. 1 fixed roller and No. 1 mobile roller bearing, and perpendicular to the sliding slot；The winding
The both ends of bar are fixed or the both ends of the winding bar are respectively arranged in two sliding slots and can move along two sliding slots；
One end of the cord is the winding end connecting with the winding bar, and the other end is expansion end, and is to wind end
Starting, according to 1~No. N sequence, the cord is alternately around between the fixed roller of identical number and mobile roller bearing, forms folding
Stack structure.
The working principle of cord retracting device of the present invention is：
When pulling cord, the end B of mobile rolling axial slide is mobile, and the spacing between fixed roller and mobile roller bearing reduces,
Cord rolls between each roller bearing, and the total length of every layer of cord accordingly reduces, thus pull out cord to outside device, pull-out
Length is about the product of " curtain cloth layer " and " fixed roller and mobile roller bearing spacing decreasing value ", realizes and opens cord；Recycle curtain
When cloth, the end A of mobile rolling axial slide is mobile, and the spacing between fixed roller and mobile roller bearing increases, cord each roller bearing it
Between roll, and the total length of every layer of cord increases accordingly, and realizes winding cord.
Relative to the rolling structure for winding cord in existing single shaft, cord retracting device of the present invention is by cord in N
It is alternately wound between a fixed roller and N number of mobile roller bearing, to form folded state, improves storage of the retracting device to cord
Ability, simultaneously because each roller bearing is all provided between two sliding slots, and each roller bearing can choose lesser diameter, so as to change
The kind larger-size problem of retracting device, makes retracting device overall volume reach smaller.And the specific value of N is visually actually needed
Depending on, by increasing fixed roller and mobile roller bearing, the folding number of plies of cord can be increased, while making the developed dimension of cord at double
Increase.

It further, further include at least two return springs, one end of the return spring is fixing end, and the other end is certainly
By holding and connecting with the mobile bearing (ball) cover, and the telescopic direction of the return spring is parallel with the sliding slot.Pass through setting
The return spring can drive mobile bearing (ball) cover mobile toward the end A of sliding slot, realize recycling cord.
Further, the mobile coiler further includes return pin, and the return pin is perpendicular to the sliding slot, and both ends are divided
It is not connect with described two mobile bearing (ball) covers, is located at No. N mobile roller bearing close to the end the A side of the sliding slot；The return
The free end of spring is connect by the return pin with mobile bearing (ball) cover, is connect with the shaft of the return pin.By setting
The return pin is set, makes return spring by driving return pin to drive mobile end cap mobile toward the end A of sliding slot, improves two
The balance of mobile bearing (ball) cover stress.
Further, the sliding slot is equipped with limited block, and the limited block is located at the end A of the mobile bearing (ball) cover and sliding slot
Between, for limiting the moving range of mobile bearing (ball) cover, reach more stable winding effect.
It further, further include the shell for offering cord outlet, the fixed coiler, mobile coiler, winding bar
It is set in the shell with two sliding slots, the expansion end of the cord is exported by the cord.
Further, N is equal to 3.By being arranged herein, the cord retracting device can be suitable for stock size size
Cord, and it takes up space small, can install and use in the small spaces such as automobile.
Further, the expansion end of the cord is equipped with the weight bar that hangs down, and is conducive to cord and reaches preferably expansion effect.
Further, further include the driving mechanism for driving the vertical heavy bar to move reciprocatingly along the sliding slot, realize cord
Automatically open and close.
