Abstract
The invention discloses a kind of ceiling blind with complex spring, including spring installation axle, the inner spring being set in spring installation axle, the outer spring being sleeved on inner spring, the roller being set on outer spring, the cord rolled up on roller, the both ends of the roller are connected to swivel and anchor tip, and the spring installation axle, inner spring, the both ends of outer spring are connected with swivel and anchor tip respectively.The present invention is provided with inside and outside spring in spring installation axle, so that in the case that the elastic force of inside and outside spring altogether is more than or equal to major diameter spring, with higher stroke, not only it is adapted to longer cord, the volume of whole ceiling blind can also be reduced, is easily installed, stores, transports, compared with traditional ceiling blind, under equal cord width, equal volume size, cord length of the invention can be longer by more than 30% than traditional.
Description
Technical field
The present invention relates to a kind of ceiling blind, and in particular to a kind of ceiling blind with complex spring.
Background technology
Ceiling blind is mainly to be used in the shading system in terms of skylight, according to operation logic can be divided into reeling type sunshade curtain,
Convertible ceiling blind of collapsible ceiling blind, blade etc..Reeling type sunshade curtain is widely used because being occupied little space after winding, volume
The structure of shaft type ceiling blind generally comprises installation axle, the roller for being arranged spring on the mounting shaft, being sleeved on spring, volume in roller
Cord on cylinder, when cord stretches, spring rotating shrinking provides tightening force for cord, cord is in straight condition, works as curtain
When the length of cloth stretching is bigger, the dynamics that spring contraction needs to use is bigger, therefore it is required that the diameter of spring and line footpath are bigger,
And when diameter and the line footpath increase of spring, the stroke of spring is reduced by, so as to cause to stretch when the width of cord is smaller
Length it is larger when, the length of spring has exceeded the width of cord, and so as to can not install, therefore the tensile elongation of cord receives
The limitation of width；Further, the spring volume and weight of major diameter and line footpath is larger, is not easy to install and uses.
The content of the invention
For overcome the deficiencies in the prior art, the present invention provide it is a kind of it is rational in infrastructure, reset great efforts, small volume it is compound
Spring ceiling blind.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of ceiling blind with complex spring, including spring installation axle, the inner spring being set in spring installation axle, set
The cord of outer spring on inner spring, the roller being set on outer spring, volume on roller, the both ends difference of the roller
Be connected with swivel and anchor tip, the spring installation axle, inner spring, outer spring both ends respectively with swivel and solid
Determine joint connection.
In the present invention, the both ends of the outer spring are fixedly connected with swivel and anchor tip respectively.
In the present invention, one end of the spring installation axle is fixedly connected with anchor tip, the other end and swivel phase
It is mutually be hinged.
In the present invention, the swivel and/or anchor tip are provided with raised plug, bullet in the plug insertion
In spring.
In the present invention, it is interference fit between the internal diameter of the plug and inner spring.
The beneficial effects of the invention are as follows：The present invention is provided with inside and outside spring in spring installation axle so that inside and outside spring closes
In the case that the elastic force to get up is more than or equal to major diameter spring, there is higher stroke, be not only adapted to longer curtain
Cloth, the volume of whole ceiling blind can also be reduced, be easily installed, store, transport, compared with traditional ceiling blind, equal
Under cord width, equal volume size, cord length of the invention can be longer by more than 30% than traditional.
Brief description of the drawings
The present invention is further described with embodiment below in conjunction with the accompanying drawings：
Fig. 1 is the structural representation of the present embodiment；
Fig. 2 is Fig. 1 A-A sectional views；
Fig. 3 is Fig. 1 part B enlarged drawing.
Embodiment
Referring to figs. 1 to Fig. 3, a kind of ceiling blind with complex spring that the present embodiment is provided, including spring installation axle
1st, the inner spring 2 that is set in spring installation axle 1, the outer spring 3 being sleeved on inner spring 2, the roller being set on outer spring 3
4th, cord of the volume on roller 4, the both ends of the roller 4 are connected to swivel 5 and anchor tip 6, and the rotation connects
First 5 follow roller 4 to rotate together, the spring installation axle 1, inner spring 2, outer spring 3 both ends respectively with swivel 5 and solid
Determine joint 6 to connect, one end of the spring installation axle 1 is fixedly connected with anchor tip 6, and the other end is mutually cut with scissors with swivel 5
Connect, swivel 5 is that axle center is rotated with spring installation axle 1.
As preferred embodiment, the both ends of the outer spring 3 are fixed with swivel 5 and anchor tip 6 respectively to be connected
Connect, outer spring 3 rotates progress accumulation of energy with swivel 5 and provides pulling force for cord, and the outer spring 3 is by bolt with turning
Dynamic joint 5 connects, and can not relatively rotate between the two.Further, the swivel 5 is provided with raised plug 7, institute
State plug 7 and insert inner spring 2, because the inwall of inner spring 2 is poroid for screw thread, plug 7 can be by along the spiral side of inner spring 2
To being rotatably inserted into, can be relatively rotated between plug 7 and inner spring 2, and when plug 7 reversely rotates, inner spring 2 is then tightly locked in slotting
On first 7, it can not be relatively rotated between plug 7 and inner spring 2, therefore, when pulling open cord, plug 7 is reversely rotated and driven interior
The rotation of spring 2 carries out accumulation of energy.As preferred embodiment, in assembling and setting, plug 7 can be rotated forward, including making plug 7
Rotated against in spring 2, because plug 7 drives rotation outer spring 3 to rotate, and inner spring 2 does not rotate, so that
It is poor to there is starting kinetic energy between inside and outside spring 2,3, when cord shrinks to the end automatically, inner spring 2 provides cushion effect, reduces
Vibrations.
Further, it is interference fit, the plug 7 between the internal diameter of the plug 7 and inner spring 2 for the ease of connecting
Diameters subtract inner spring 2 internal diameter numerical value be more than or equal to inner spring 2 line footpath numerical value half.For energy further
Ground strengthens the tensile elongation of cord length, and the spring installation axle 1 is divided to for the extension sleeve structure of two sections, two section extension sleeves point
For rotatable initiative part and follower, the initiative part is connected with swivel 5, and follower is connected with anchor tip 6.
In the present embodiment, the spring installation axle 1 can not only be arranged with inside and outside spring 2,3, can also be in outer spring
Multiple springs are arranged on 3, there is identical technology.Also, the technical program can not only be applied on ceiling blind, can also apply
It is applied widely on roller shutter.
The preferred embodiments of the present invention are the foregoing is only, as long as realizing the skill of the object of the invention with essentially identical means
Art scheme is belonged within protection scope of the present invention.
