Description

[0002] Electric mesh blinds [0003]

The present invention relates to an electric network blind, more particularly, to a simple structure in which a V-shaped ring is wound while a mesh screen is wound on a rotary shaft, and a V-shaped ring is lowered in a state where the V- So that the net screen can be smoothly operated in a taut state.

As shown in FIG. 1, the roll screen net 9 includes a body 1 provided with rollers for winding and holding a mesh-like or opaque screen fabric 2 made of glass fiber or polyester material, A guide rail 3 installed at both sides of the body 1 for guiding both ends of the fabric 2 and a fabric 2 fastened to the guide rail 3 at a lower end of the fabric 2 And a fixture 5 which is provided below the guide rail 3 and fixes or releases the grip 4.

[0004] Fixing protrusions are formed on both ends of the handle 4, and hooks corresponding to fixing protrusions are provided on both sides of the fixture 5.

The roll insecticide 9 as described above has the handle 2 formed at the lower center of the fabric 2 and the lower end of the knitted fabric 4 is fixed to the fixture 5 so that the fabric 2 covers the entire surface. At this time, the fixing protrusion of the handle 4 is engaged with the hook of the fixture 5.

In this state, when the knob 4 is pushed downward, the fixing protrusion is released from the hook of the fixing hole 5, and the fabric 2 is wound up and opened.

However, when the roll insect nets 9 and the raw fabric 2 of the roll screen are installed in a window having a weak width and a large force to maintain the original state, the fabric tends to come out or wobble depending on the intensity of the incoming wind .

In addition, there is a problem that the horizontal portion can not be maintained due to the load of the fabric, and the central portion is often hung down.

In order to solve such a problem, a utility model registration No. 422720, "Fabric support structure of insect screen and roll screen" has been disclosed.

2, a guide rail 10 having an insertion hole 12 at the front center and a release preventing tab 11 formed on both sides of the inner rear of the guide rail 10, A fixing plate 20 which is inserted into the connecting hole 21 and is connected to the connecting hole 21 by a spring 40 and which is provided with a spring 40 at the rear center, And a control hole 30 having a connecting hole 31 to be connected and having a space 32 therein and a guide hole 33 formed on the front surface of the space 32.

However, the above-mentioned design has a disadvantage in that the structure is complicated and a lot of parts are required, and thus the manufacturing cost is low and the price competitiveness is poor. In addition, the structure applied to the passive roll insect screen and the roll screen is not smooth There is a problem that the fabric is wrinkled or discharged to the outside of the guide rail and can not be used.

In addition, the above design has a disadvantage that it can not be applied to a screen made of a wire net.

The object of the present invention is to solve the above-mentioned problems, and it is an object of the present invention to provide a V-shaped wire which is wound while a mesh screen made of stainless steel is wound around a rotary shaft, The mesh screen can be smoothly operated with a simple structure, and the mesh screen is smoothly operated.

In order to achieve the above-mentioned object, the present invention provides an upper case having an upper case having a mesh screen on its outer surface and a rotating shaft rotated by the power of the motor, and a lower case disposed on both side ends of the upper case, A mesh screen which is connected to the guide protrusion and is made of stainless steel and has a V-shape formed by bending both sides inwardly at both sides thereof; A finishing cap inserted into a lower end of the guide rail and formed with a lower end bar insertion groove in a transverse direction and having a rail fastening groove formed in a longitudinal direction; Is wound in a compressed state, and when the V-shaped ring is unfolded, Lowered to is characterized in that to hold the left and right reversed tight state of the screen mesh.

When the mesh screen is wound around the rotary shaft, the V-shaped ring is wound in a compressed state, and when the mesh screen is lowered, the V-shaped ring is lowered in a state constrained to the guide protrusion. , And the net screen is always kept in a taut state by using the net screen tension.

In the drawings, reference numeral 200 denotes an electric net blind of the present invention.

The electric screen screen blind 200 includes an upper case 210 having a rotation shaft 212 and a motor 213 installed therein and a guide 220 having a guide protrusion 222 to which a hook 231 of the screen 230 is fastened. A lower end bar 240 fixed to the lower end of the screen 230 and a lower end bar 240 installed at a lower end of the guide rail 220. The upper end of the lower end bar 240 is connected to the upper end of the lower end bar 240, And a finishing cap 250 to which the cap 240 is fastened.

The upper case 210 is a case having an inner space and has an entrance hole 211 through which the screen 230 enters and exits at the center of the lower side and a circular shape A rotary shaft 212 is provided.

A motor 213 is installed on one side of the rotation shaft 212. The power of the motor 213 causes the screen 230 to rotate up and down while rotating the rotating shaft 212.

The guide rail 220 is a square frame having an inner space and an open top and a bottom. The guide rail 220 forms a passage 221 through which the screen 230 can move up and down.

A guide protrusion 222 bent toward the direction opposite to the direction of the passage 221 is formed inside the passage 221 and the ring 231 of the mesh screen 230 is fastened to the outer surface of the guide protrusion 222 .

The guide rails 220 are installed at both lower ends of the upper case 210 so that the passages 221 face each other.

When the loop 231 of the net screen 230 is fastened to the guide protrusion 222, the V-shaped hook 231 is fastened in a state of being open and supported by the guide protrusion 222.

The mesh screen 230 is formed of a stainless steel material so as to be easily widened to the left and right and bent at both ends inward to form a V- .

The lower bar 240 is fixed to the lower end of the net screen 230 and is inserted into the lower bar insertion groove 251 of the lower end of the finishing cap 250 provided at the lower end of the guide rail 220.

6, the lower end bar insertion groove 251 is formed in the horizontal direction and the rail coupling groove 252 in which the lower end of the guide rail is inserted in the vertical direction is formed in the finishing cap 250 .

When the lower end 220 of the guide rail is installed in the rail engaging groove 252, the front 253 of the finishing cap 250 protrudes outward.

The operation state of the present invention will be described as follows.

Power is supplied to the motor 213 provided in the inner space of the upper case 210 and the mesh screen 230 is wound around the outer surface of the rotating shaft 212 while the rotating shaft 212 is rotated by the power of the motor 213 .

7, the V-shaped hooks 231 at both ends of the screen 230 are detached from the guide protrusions 222 of the guide rail 220, and the V-shaped hooks 231 are compressed The screen 230 is lifted up while the lower bar 240 is lifted up to the upper end of the upper case 210 while being wound around the rotary shaft 212.

At this time, the lower V-shaped hook 231 of the mesh screen 230 is maintained in a state of being fastened to the guide protrusion 222.

In this state, when the rotation shaft 212 rotates in the opposite direction, the mesh screen 230 descends downward, and the pressed V-shaped hook 231 is restrained by the guide protrusion 222, The left and right sides become strained.

In the drawings, reference numeral 200 denotes an electric net blind of the present invention.
