Summary of the invention:
Technical problem to be solved by this invention is to provide one can realize flat opening, and there is safeguard function open protection integrated screen window for the flat of casement window.
Above-mentioned purpose is achieved in that it comprises gauze fan and ryce, and gauze fan is equipped with gauze; It is characterized in that: gauze fan is contained on ryce by hinge.
Described ryce is formed by connecting by upper ledge, lower frame, left frame and right frame, and upper ledge, lower frame, left frame are all identical with the structure of right frame, all comprise the big frame that cross section is quadrangle, the outer wall of big frame are fixed with the small frame that cross section is quadrangle.
For the ease of being arranged on bridge-cut-off horizontal drawing window, rib can be fixed on the outer wall of small frame.
In order to make it have safeguard function, correspondingly on the big frame of the big frame of the left frame of ryce and the right frame of ryce can establish several guardrail holes, the two ends of guard rail rod are inserted in the guardrail hole on the big frame of the left frame of ryce and the big frame of the right frame of ryce respectively.
For the ease of the installation and removal of guard rail rod, slideway can be established in the big frame of the left frame of ryce or the right frame of ryce, also comprise bolt, there is chute the both sides of bolt, the chute of bolt both sides is contained in the slideway in big frame, bolt is also provided with accordingly frame left with ryce identical with guardrail hole number on right frame, guardrail hole of the same size, elongated hole is arranged at the bottom of bolt, the lock body buied from market is also equipped with in the big frame bottom of the left frame of ryce or right frame that bolt is housed, cranking arm on lock body extend in the elongated hole of bolt, key is inserted in lock body, screw key can drive the rotation 180 ° of cranking arm on lock body, thus drive in the slideway of bolt in big frame, lower slider, make guardrail hole on guardrail hole on bolt and the big frame of the left frame of ryce and the big frame of right frame at grade, or stagger up and down in the guardrail hole on itself and the big frame of the left frame of ryce and the big frame of right frame.
In order to prevent the gauze fan after closing from opening voluntarily, lock can be established on gauze fan sliding, ryce establishes latch hook in the position that correspondence lock is sliding.
Advantage of the present invention is: during use, attaches it on casement window with screw, and because its gauze fan is arranged on ryce by hinge, so can realize flat opening, switch screen window is convenient; Again owing to being provided with guard rail rod on ryce, so have safeguard function, security performance is good, guard rail rod easy installation and removal.
The method of installing/dismounting guard rail rod: such as, in the big frame of the left frame of ryce, bolt is installed, when guard rail rod is installed, screw key, rotation 180 ° of cranking arm on lock body, drive bolt upward sliding, guardrail hole now on bolt is just in time relative with the guardrail hole on ryce left frame big frame and ryce right frame big frame, namely at grade, because the length of guard rail rod is slightly larger than the distance between ryce left frame big frame and the right frame big frame of ryce, so first one end of guard rail rod is inserted in the big frame of the left frame of ryce when installing, guard rail rod can be protruding from the guardrail hole of bolt, so just suffer in the guardrail hole other end of guard rail rod can be inserted on the right frame big frame of ryce, then guard rail rod is moved in the right frame big frame of ryce, the guard rail rod stretched out outside bolt guardrail hole is made to get back between the left frame big frame of ryce and bolt, screw key again, rotation 180 ° of cranking arm on lock body, drive bolt slide downward, stagger up and down in guardrail hole on guardrail hole now on bolt and ryce left frame big frame and the right frame big frame of ryce, this end of guard rail rod withstands on the upper of bolt, between lower two guardrail holes, during dismounting guard rail rod, first screw key, rotation 180 ° of cranking arm on lock body, drive bolt upward sliding, guardrail hole now on bolt is just in time relative with the guardrail hole on ryce left frame big frame and ryce right frame big frame, namely at grade, makes one end of guard rail rod protruding from the guardrail hole of bolt, so just the other end of guard rail rod can be unloaded from the guardrail hole of the right frame big frame of ryce, namely take off whole guard rail rod.
Detailed description of the invention:
With reference to Fig. 1-4, it comprises gauze fan 2 and ryce 1, gauze fan is equipped with gauze 5; Gauze fan 2 is contained on ryce by hinge 6.
Described ryce is formed by connecting by upper ledge, lower frame, left frame and right frame, and upper ledge, lower frame, left frame are all identical with the structure of right frame, all comprise the big frame 7 that cross section is quadrangle, the outer wall of big frame are fixed with the small frame 8 that cross section is quadrangle.
For the ease of being arranged on bridge-cut-off horizontal drawing window, rib 10 can be fixed on the outer wall of small frame.
In order to make it have safeguard function, if correspondingly on the big frame 7 of the big frame 7 of the left frame of ryce and the right frame of ryce can establish a dry guardrail hole 13, the two ends of guard rail rod 4 are inserted in the guardrail hole on the big frame of the left frame of ryce and the big frame of the right frame of ryce respectively.
For the ease of the installation and removal of guard rail rod, slideway 14 can be established in the big frame of the left frame of ryce or the right frame of ryce, also comprise bolt 9, there is chute the both sides of bolt, the chute of bolt both sides is contained in the slideway 14 in big frame, bolt is also provided with accordingly frame left with ryce guardrail hole 13 identical, of the same size with guardrail hole number on right frame, elongated hole 15 is arranged at the bottom of bolt, lock body 11 is also equipped with in the big frame bottom of the left frame of ryce or right frame that bolt is housed, and cranking arm on lock body 12 extend in the elongated hole 15 of bolt.
In order to prevent the gauze fan after closing from opening voluntarily, lock sliding 3 can be established on gauze fan, ryce establishes latch hook in the position that correspondence lock is sliding.
