Description

Technical Field

[0001] The utility model relates to the technical field of household decoration products, in particular to a casement window locking device. Background Art

[0002] In architecture, a window refers to an opening built on a wall or roof to allow light or air to enter a room. As early as the Sui Dynasty in China, the Guanwen Hall in the Ziwei City of the Luoyang Imperial Palace had windows that could open and close automatically. Modern windows are composed of three parts: window frames, glass, and movable components (hinges, handles, pulleys, etc.). The window frame is responsible for supporting the main structure of the window, which can be made of wood, metal, ceramic or plastic. The transparent part is attached to the window frame and can be made of paper, cloth, silk or glass. The movable components are mainly made of metal materials, and may also be wrapped with insulating materials such as plastic where people touch them.

[0003] The application number is CN201820270447.4, which discloses a casement window sliding support device with a locking function, including a slide slot, a short overhang, a middle overhang, a long overhang, a support arm, and a slider that can slide in the slide slot, one end of the short overhang and one end of the middle overhang are hinged to the slide slot through the same rivet, the other end of the short overhang is hinged to one end of the support arm, the other end of the middle overhang is hinged to the middle of the long overhang, one end of the long overhang is hinged to the middle of the support arm and the other end is hinged to the slider, the end of the slider away from the rivet is connected to an elastic buckle, and the slide slot is provided with a lower notch that cooperates with the elastic buckle to lock the slider. This case realizes the integrated setting of the sliding support structure and the locking structure, which is conducive to improving market competitiveness and has good practicality.

[0004] Although the above-mentioned utility model includes a slide slot, a short suspension, a middle suspension, a long suspension, a support arm, and a slider that can slide in the slide slot, one end of the short suspension and one end of the middle suspension are hinged to the slide slot through the same rivet, the other end of the short suspension is hinged to one end of the support arm, the other end of the middle suspension is hinged to the middle part of the long suspension, one end of the long suspension is hinged to the middle of the support arm and the other end is hinged to the slider, the end of the slider away from the rivet is connected with an elastic buckle, the slide slot is provided with a lower recess that cooperates with the elastic buckle to lock the slider, realizing the integrated setting of the sliding support structure and the locking structure, which is conducive to improving market competitiveness and has good practicality, but the disadvantage is that the locking of the middle device during use requires a secondary step, so this is relatively not convenient enough.

[0005] Therefore, it is necessary to install a locking component on the device so that when the window is pushed closed, the automatic locking mode can be achieved. This method can avoid the cumbersome steps of locking and also avoid the situation where the amnesiac forgets to lock the door when going out, resulting in the loss of the house.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1 - Figure 4 As shown, the utility model is a casement window locking device, comprising a window assembly 1, an unlocking assembly 2 is installed on one side of the middle of the window assembly 1, and a locking assembly 3 is correspondingly installed on the bottom thereof.

[0027] By installing the locking assembly 3 on the device, the automatic locking mode can be realized when the window is pushed closed, which can avoid the cumbersome steps of locking and also avoid the situation that the amnesiac forgets to lock the window when going out and causes the loss of the window at home.

[0028] The window assembly 1 comprises a frame 101 , and slide grooves 102 are provided on the inner sides of the top and bottom of the frame 101 . A window 103 is installed inside the slide groove 102 , and is pushed and pulled back and forth through the slide groove 102 at the top.

[0029] The unlocking component 2 includes an unlocking block 201, a rotating shaft 204 is installed on the outer side of the unlocking block 201, and a limiting plate 205 is installed on the inner end, and a curved handle 202 is installed on the outer side of the rotating shaft 204, and a grip 203 is installed on the end of the curved handle 202, and a return spring 206 is installed on the inner side of the limiting plate 205, and the other side of the return spring 206 is installed on the inner wall of the frame 101. By adding a locking setting to the unlocking component 2 of the device, it is possible to prevent children from accidentally touching the door after locking, thereby avoiding the danger of children accidentally touching the door and improving a certain safety factor.

[0030] The locking assembly 3 includes a limit block 301, a plurality of small return springs 302 are installed on the bottom side of the top of the limit block 301, and a tension plate 303 is installed on the top of the limit block 301, a large return spring 304 is installed on the top of the tension plate 303, and a pull plate connecting shaft 306 is installed at the end thereof, a rotating rod 307 is installed in the middle of the pull plate connecting shaft 306, and a rotating shaft 2 308 is installed on the front side of the rotating rod 307, the large return spring 304 has a toughness greater than the small return spring 302, and a spring mounting base 3 is installed at the bottom thereof 05. By setting the toughness of the large return spring 304 to be greater than that of the small return spring 302, when the pull plate connecting shaft 306 has no force and the tension plate 303 is not under force, the limit block 301 at the bottom can be pushed out through the large return spring 304. Then, when the upper handle 203 is pressed downward, the large return spring 304 is squeezed by pulling the pressure plate 303 to make the limit block 301 at the bottom move upward through the small return spring 302 and retract into the slot to complete the unlocking.

[0031] A sliding groove 1011 is formed at the top of the frame 101 , and a limiting groove 1012 is formed at the front end of the bottom thereof.

[0032] The window 103 includes a slider 1031, a locking cavity 1032 and a push groove 1033. The slider 1031 is installed on both sides of the top of the window 103, the locking cavity 1032 is opened at the bottom of one side of the window 103, and the push groove 1033 is opened in the middle position of one side of the window 103, and an unlocking block 201 is installed therein.

[0033] When using this device, when closing the window 103, the limit block 301 at the bottom can, under the action of the large return spring 304 at the top, make the window 103 correspond to the limit groove 1012, and the limit block 301 will fall and realize the locking work. When it is necessary to unlock and open the window, the unlocking block 201 in the unlocking component 2 is pushed in, and the shaft 2 308 is driven by the shaft 1 204 and connected to the upper rotating rod 307 for rotation. Then, the pull plate 303 is pulled by the rotation of the pull plate connecting shaft 306 at the rear side so that it compresses the large return spring 304 at the bottom. At this time, the limit block 301 at the bottom is contracted by the small return spring 302 arranged around it to complete the unlocking.

[0034] The preferred embodiments of the utility model disclosed above are only used to help explain the utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the utility model to the specific implementation methods described. Obviously, many modifications and changes can be made according to the content of this specification.
