Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1, the fire window disclosed by the present invention includes a fixedly installed window frame 1, a window sash 2 having one side rotatably installed on the window frame 1, and fire-proof glass 3 fixedly installed in the middle of the window sash 2. The window frame 1 is a rectangular frame structure, the window sash 2 is a rectangular frame structure with one side rotatably installed in the window frame 1, and the fireproof glass 3 is embedded in the window sash 2 to form a transparent lighting part of the fireproof window. Fireproof glass 3 sets up to the bilayer, and the evacuation increases fire behavior and the holistic intensity of fire prevention window between the double-deck fireproof glass 3. The window frame 1 and the window sash 2 are both made of fireproof steel frames, and flame retardant paint is sprayed on the surfaces of the steel frames, so that the overall fire-resistant and smoke-insulating performance of the window is improved.
Referring to fig. 1 and 2, a blocking frame 11 is arranged in the inner circumference of the window frame 1, the blocking frame 11 is a rectangular frame with the inner diameter smaller than the outer diameter of the window sash 2, when the window sash 2 is closed, the end face, facing the window frame 1, of the window sash 2 abuts against the blocking frame 11, and the sealing performance between the window sash 2 and the window frame 1 in the closed state is improved by matching the abutting sealing state formed by the window sash 2. Casement 2 deviates from terminal surface outside circumference fixedly connected with closing plate 4 of window frame 1, and closing plate 4 is the annular plate that extends along 2 circumference of casement, and the external diameter of closing plate 4 is greater than the internal diameter of window frame 1, removes the joint gap that is connected one side with window frame 1 and covers casement 2 and window frame 1 in 2 circumference of casement, utilizes closing plate 4 butt window frame 1 when casement 2 closes, covers the space between casement 2 and the window frame 1, increases the leakproofness under the 2 closed states of casement. Sealing strip 41 is laid in the one side circumference of sealing plate 4 towards window frame 1, and sealing strip 41 adopts the elastic rubber material, lays along sealing plate 4 edge, and when sealing plate 4 butt window frame 1, the elasticity deformation of utilizing sealing strip 41 increases the butt leakproofness of sealing plate 4 and window frame 1.
Referring to fig. 2 and 3, a rotatable handle 5 is mounted on the movable side of the sash 2 away from the side fixed to the frame 1. The terminal surface mid-mounting that casement 2 deviates from window frame 1 has mount pad 51, and handle 5 rotates to be installed on mount pad 51, and the rotation installation of handle 5 can enough realize the convenient operation that casement 2 opened and shut through handle 5 and realize closing of casement 2 fixed simultaneously through the rotation of handle 5. One end of the handle 5 extending into the window sash 2 is sleeved with a gear 52, and the gear 52 is fixedly sleeved at the end of the handle 5 and rotates along with the rotation of the handle 5. The side wall of the window sash 2 is provided with a slidable locking plate 6, and the locking plate 6 is strip-shaped and is movably mounted close to the side wall of the window sash 2. The side wall of the locking plate 6 close to the handle 5 is paved with a rack 61, the rack 61 is meshed with the gear 52, and the handle 5 rotates to enable the gear 52 to rotate so as to drive the rack 61 to move vertically, so that the locking plate 6 can slide in the vertical direction.
The locking plate 6 is provided with a locking column 62 protruding from the locking plate 6 at the upper and lower ends, the locking column 62 is a cylindrical block axially perpendicular to the locking plate 6, and the window frame 1 is provided with a fixing piece 12 for fixing and blocking the locking column 62 at the inner side close to the end face of the window sash 2. When the handle 5 rotates to be in a horizontal state, the lock column 62 moves to a position which is not consistent with the height of the fixing piece 12 in the rotating process of the handle 5, so that the window sash 2 rotates to be closed, then the handle 5 rotates to drive the locking plate 6 to vertically slide, the lock column 62 slides to the inner side of the fixing piece 12, the fixing piece 12 fixes the blocking lock column 62, and the window sash 2 is kept in a closed and locked state. The handle 5 facilitates opening and closing of the window sash 2 and also secures the window sash 2 in a closed state.
Referring to fig. 2 and 4, the locking plate 6 is provided at a middle portion thereof with a clamping member 7, and the clamping member 7 increases the sealing degree of the window sash 2 with the window frame 1 in a closed state of the window sash 2. Clamping piece 7 includes fixing base 71 and shell fragment 72, and fixing base 71 fixed mounting is in the middle part of jam plate 6, and fixing base 71 is towards window frame 1 one side open-ended hollow rectangular block, and shell fragment 72 is that one end is bent and is stretched into in fixing base 71 and one end is the three folded sheet piece of L shape, and the part that exposes of shell fragment 72 sets up the inboard at closing plate 4. One end of the elastic sheet 72 extending into the fixing seat 71 is fixedly connected with a pressing spring 73, and the other end of the pressing spring 73 is fixedly connected with the fixing seat 71. When the window sash 2 is closed, the exposed L-shaped part of the elastic sheet 72 abuts against the window frame 1, the sealing plate 4 continuously compresses the elastic sheet 72 in the process of tightly closing the window sash 2, the compression spring 73 is compressed and stressed, reverse thrust is formed on the elastic sheet 72, the two ends of the elastic sheet 72 respectively abut against the window frame 1 and the sealing plate 4 under the two-way thrust of the sealing plate 4 and the compression spring 73, the sealing degree of the sealing plate 4 and the window frame 1 is increased, and meanwhile, the L-shaped part is utilized to abut against and seal a gap between the window sash 2 and the window frame 1.
The implementation principle of the embodiment is as follows: the inboard frame 11 that keeps off that sets up of window frame 1, it is sealed to form the butt under the closed condition to casement 2, set up closing plate 4 on casement 2, it is sealed to form the butt through butt window frame 1 when casement 2 is closed, add sealing strip 41 simultaneously, further increase the sealed closure of casement 2 and window frame 1, set up handle 5 on casement 2, when being convenient for casement 2 to open and close, the rotation through handle 5 realizes that lock post 62 vertically slides, cooperation stationary blade 12 on the window frame 1, the realization is fixed under the closed condition to casement 2.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
