The present invention relates to a handle fixing structure of a roll type insectproof room, and more particularly to a handle fixing structure of a roll type insect control net which is easy to assemble, simple to use, and minimizes a failure rate.

In general, doors and windows of apartments and houses are provided with insect screens for blocking insects such as mosquitoes and flies. The insect screen uses a dense grid net to block the infestation. In recent years, an insect net has been developed and used in which a net is formed into a roll type as shown in Registration Practice Model No. 20-0400990, so that the insect net can be easily opened and closed .

1, the roll type screen 10 according to the related art includes a vertical frame 11 and a rear frame 12 disposed opposite to each other, and a vertical frame 11 and a vertical frame 11 disposed at the upper and lower ends of the vertical frames 11 and 12, respectively. A winder rod 15 which is rotatably and slidably installed between the horizontal frames 13 and 14 and the horizontal frames 13 and 14 which are coupled to each other so as to be slidable on one side of the winder rod 15; A net 17 to which one end, a middle portion, and the other end are fixed to the vertical frame 11, the winding rod 15, and the handle bar 16, respectively, And a handle 18 mounted on the handle bar 16.

In this case, the handle 18 generally has a function as a grip portion for opening and closing the net 17 and a function as a locking device for keeping the net 17 in a closed state. However, in the case of the roll insecticide 10 according to the related art, there is a problem that the fixing structure of the handle 18 is complicated and difficult to assemble.

2, the fixing structure of the handle 18 of the roll type insect screen according to the related art includes a latching jaw 19 provided on the handle bar 16, a spring 20 mounted on the vertical frame 12, And a hook 21 which is slidably installed in the vertical direction. Therefore, in order to assemble the handle 18 during the production of the roll type insect protection net 10, the positions of the latching jaws 19 and the hooks 21 must be precisely adjusted and fixed with bolts 22 or the like. However, it is difficult and cumbersome to precisely match the positions of the latching jaws 19 and the hooks 21. Even when the position is accurately adjusted, the position is changed in the process of fixing with the bolts 22, so that an error necessarily occurs So that it is impossible to implement a function as a locking device. In particular, considering the trend of popularizing DIY products for assembling parts directly by consumers in order to lower the selling prices of products, it is more difficult for general consumers to perform the above-mentioned tasks.

According to the related art, since the knob 18 must be lowered in order to open the net 17, it is inconvenient to use, and when the knob 16 is forcibly slid while the operating principle is not known, The hook 21 is broken and a failure occurs.

The present invention has been conceived to solve the problems of the prior art described above, and it is an object of the present invention to provide a handle fixing structure of a roll type insect screen which can be easily assembled not only for a worker but also for a general consumer, The purpose is to do.

A handle fixing structure for a roll type insect-protection net including a handle bar slidably installed between frames and a handle provided on the handle bar, the handle fixing structure comprising: a handle member coupled to the handle bar; A magnet provided on the handle member; And a metal piece fixed to the vertical frame so as to be grounded with the magnet.

In this case, the handle bar may have a first protrusion protruding in the longitudinal direction and a second protrusion protruding in the lateral direction.

In this case, the pull-tab can be fitted to the pull-tab bar.

In this case, the pull-tab may include a body for insertion of the first projection; A mounting portion extending laterally from the body portion and having a groove formed therein for insertion of the second projection; And an introducing portion formed in an open form at a rear end of the mounting portion and connected to the groove, wherein the introducing portion has a shape tilted inward toward the groove so that when the pulling member is pressed against the pull bar, The first projection may be inserted into the body portion and the introduction portion may be forcibly expanded by the second projection so that the second projection is inserted into the groove and then restored.

According to the present invention, instead of the physical hook fastening structure, the knob of the insecting net is fixed by using the magnetic force of the magnet, so that the knob fastening structure can be easily and quickly assembled and the failure rate can be minimized.

In addition, since the separate operation for releasing the locking device is unnecessary, the opening and closing of the insect screen can be easily performed.
