Description
Technical field
The present invention relates to projection accessories fields, and winder is overlapped more particularly to a kind of steel wire of screen of dynamoelectric projection.
Background technology
Screen of dynamoelectric projection has been widely used in the range of the world at present.Either people are in viewing film
When the still projection demonstration in convention or classroom, be unable to do without screen of dynamoelectric projection, screen of dynamoelectric projection perfectly melts
It closes in daily life.
With the extensive use of screen of dynamoelectric projection, problem is also gradually found present on some screen of dynamoelectric projection.It is existing
The cabling mode of screen of dynamoelectric projection in technology puts down away transmission using nylon tape transmission and wire, and nylon tape transmission can not be born
In heavier object, therefore uses and be limited, and good but traditional can only the putting down away of wire transmission bearing capacity makes steel without being overlapped
Silk is easy dislocation when walking, and cannot make corrections precision, makes integrated stand so that reducing transmission efficiency and walking bit wide because of wire
Structure seems heavy.
Invention content
The purpose of the present invention is to provide a kind of steel wires of screen of dynamoelectric projection to be overlapped winder, to solve the prior art not
Foot, improves the transmission efficiency of the lead of screen of dynamoelectric projection, improves the structure of the coiling storage space of lead especially wire, have
Effect prevents lead (especially wire) overlapping spiral from generating inconsistent phenomenon in the process.
In order to solve the above technical problems, the technical solution taken:A kind of steel wire of screen of dynamoelectric projection of the present invention is overlapped spiral
Device, includes the lead of tube and connection tube, and the tube is socketed with the first spiral seat and the second spiral seat, first spiral
The coiling cavity for winding lead is formed between seat and the second spiral seat, the width of coiling cavity is slightly larger than lead so that draws
Line can be uniformly wrapped in coiling cavity just, effectively prevent from generating dislocation during lead overlapping spiral, described
Remote tube end between the first spiral seat and the second spiral seat mutually forms recessed circle, and conductor loop, institute are equipped in the recessed circle
It states and is set respectively (especially between the contact surface of tube radial direction) between the contact surface of conductor loop and the first spiral seat, the second spiral seat
There are sliding component, tube, the first spiral seat and the second spiral seat to be fixed together, rotates synchronously, and conductor loop remains stationary as, and
Sliding component plays the role of eliminating the power that tube, the first spiral seat and the second spiral seat drive conductor loop rotation, the conducting wire
The position that ring corresponds to coiling cavity is provided with an outlet hole, for being pierced by for lead.
As the improvement of above technical scheme, sliding component of the present invention is a circle ball, and the sliding component may be used also
To be other component, even, sliding component can be common with the recessed circle bottom surface of conductor loop and the first spiral seat, the second spiral seat
The component of similar bearing is constituted, as long as realizing that conductor loop is opposing stationary, is not rotated with tube, the first spiral seat and the second spiral seat
And rotate, the conductor loop and the first spiral seat, the second spiral seat contact surface between be equipped with and rolled for a circle ball
The cricoid rolling friction slot of dynamic friction, the generally side in the both sides of conductor loop and the recessed circle of the first spiral seat and the second spiral seat
Face setting for one circle ball carry out rolling friction cricoid rolling friction slot, above-mentioned rolling friction slot can define why steel ball
Contact surface is not complete smooth slot, and shape can be that cross sectional shape is polygon axisymmetricly, and the quantity of ball can root
According to specifically needing to be arranged, technical solution can be obtained by the experiment of finite number of time, does not do to tire out herein and state, due to ball and rolling
The contact surface of dynamic friction slot is not full shiny surface so that for tube when driving lead movement, conductor loop will not be with the rotation of tube
And rotate, outlet hole keeps the cabling of horizontal vertical direction realization lead.
As the improvement of above technical scheme, the first spiral seat of the present invention, the second spiral seat two prolong far from end and turn
The axial component of pipe stretches out, in the first spiral seat, the first spiral shell of the extension of the second spiral seat being radially provided with through tube
Wire hole and the first screw coordinated with the first screw hole so that more steady between the first spiral seat, the second spiral seat and tube
Gu, it is ensured that precision.
As the improvement of above technical scheme, tube of the present invention is socketed with the compression for compressing the second spiral seat
The respectively mutually embedded trapezium structure of the contact jaw of seat, the pressed seat and the second spiral seat, the radial direction of the pressed seat are set
There are the second screw hole for running through tube and the second screw coordinated with the second spiral shell screw hole, when gradually tightening the second screw, pressure
Tight seat can gradually apply extruding force to the second spiral seat, so that second spiral seat Step wise approximation the first spiral seat, can adjust
Improve storage space.
As the improvement of above technical scheme, the first spiral seat of the present invention and the second spiral seat are threadedly coupled,
The corresponding junction of coiling cavity be provided with for lead by through-hole, can make the first spiral seat and the second spiral seat and turn
Connection between pipe is more firm, and being axially and radially vertically arranged for junction ensures while stable degree increases
Precision.
As the improvement of above technical scheme, lead of the present invention passes through tube and is fixed on the inside of tube, according to
Particular situation is arranged, and the connector of the lead can be arranged in tube wall, and the connector of lead can also pass through tube to be arranged
In the inner wall of tube, ensure that lead does not slip.
As the improvement of above technical scheme, lead of the present invention is wire, it should be noted that the present invention is main
It is the lead using wire, while the lead of other metals, such as the alloy with certain tensile strength can also be applied
Copper lead.
Technical solution of the present invention compared with the existing technology, the advantageous effect of acquirement：Structure of the invention stable degree protrudes, and has
Good precision can effectively improve the transmission efficiency of the lead of screen of dynamoelectric projection, improve the coiling of lead especially wire
The structure of storage space prevents lead overlapping and cabling dislocation.
