Description

Technical Field

[0001] The utility model relates to the technical field of outward-opening windows, in particular to an outward-opening window. Background Art

[0002] Existing utility model patent CN207700911U discloses an outward-opening window. The key technical solution is an outward-opening window comprising a window sash and a window frame. The window sash is slidably connected to a linkage rod that drives a hook to rotate. The linkage rod is fixedly connected to a sliding block. The window sash is provided with a slide groove that guides the sliding travel of the sliding block. The sliding block is slidably connected to a locking assembly for locking the sliding block. The slide groove is provided with a locking groove that cooperates with the locking assembly to lock the sliding block. The locking groove is slidably connected to an unlocking assembly for unlocking the sliding block. The sliding of the sliding block drives the hook to snap into the groove to complete the locking of the window sash. The locking assembly fixes the slider, making the locking between the window sash and the window frame more secure.

[0003] However, its structure is complex, the assembly process is difficult, the cost is high, and the locking strength is still not high. Utility Model Content

[0004] The technical problem to be solved by the present invention is: in order to overcome the above problems, an outward-opening window is provided, which solves the above problems.

[0005] The utility model solves the technical problem by adopting the following technical solutions:

[0006] An outward-opening window comprises a window frame and a glass frame hinged to the window frame, a glass window being sealed and fixedly provided in the middle of the glass frame, a hand-twisted lock handle being provided on the side of the glass frame for rotating and locking the window frame to enable pushing and pulling, and two upper and lower symmetrical locking structures being provided on the movable side of the glass frame, the locking structures being automatically reset by a spring and being snap-locked and locked by a latch structure.

[0007] Preferably, a hollow cavity running through the upper and lower sides is provided on the side of the glass frame, and two safety slide bars of different lengths are movably inserted in the cavity, and a snap lock body is fixedly provided at the end of the safety slide bar, and a retaining ring is fixedly provided in the middle of the safety slide bar, and the retaining ring is supported by a spring, and the other end of the spring is supported on the glass frame. The spring pushes the safety slide bar outward, and when the glass frame is closed, the snap lock body is supported against the inner wall of the window frame and compresses the spring.

[0008] Preferably, an arc surface is provided at the end of the snap lock body, and a semicircular bayonet for inserting the snap lock body is provided on the upper and lower inner walls of the window frame. After the snap lock body is inserted into the semicircular bayonet, the glass frame can be set, and then the upper, middle and lower three-point fixation is achieved on the movable side of the glass frame, which effectively improves the closing strength and sealing performance.

[0009] Preferably, a slot is provided on the indoor side of the glass frame, and a paddle is fixedly provided at the other end of the safety slide bar and exposed in the slot. The paddles are unlocked by pressing them close to each other, and then the hand-twist lock handle is turned to open the glass frame. This design has better anti-accidental touch and protection effect on children than the traditional single hand-twist lock handle.

[0010] Preferably, in order to facilitate the extension and retraction of the safety slide bar, a guide slope pointing to the semicircular bayonet is provided on the outer side of the window frame, and the oblique guiding effect of the guide slope makes the safety slide bar extend and retract more smoothly.

[0011] The advantages and positive effects of the utility model are:

[0012] The structure is simple and the assembly is convenient. When closing, no operation is required. The spring will push the lock automatically, so that the upper, middle and lower points of the movable side of the glass frame are well fixed and the sealing effect is improved.

[0013] This structure requires pinching the two picks at the same time and then turning the hand-twisted lock handle, which effectively increases the continuity of the synchronous operation and has a better effect in avoiding accidental touches and preventing children from operating.

DETAILED DESCRIPTION

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating the basic structure of the present invention in a schematic manner, and therefore only show components relevant to the present invention. The following is a further detailed description of embodiments of the present invention with reference to the accompanying drawings:

[0019] like Figure 1-2 As shown, the outward-opening window described in the utility model includes a window frame 10 and a glass frame 12 hinged on the window frame 10, a glass window 15 is sealed and fixed in the middle of the glass frame 12, and a hand-twisted lock handle 11 is provided on the side of the glass frame 12 for rotating and locking in the window frame 10 and realizing pushing and pulling. In addition, two upper and lower symmetrical locking structures are provided on the movable side of the glass frame 12, and the locking structure is automatically reset by a spring and is locked by a latch structure.

[0020] Preferably, a hollow cavity is provided on the side of the glass frame 12, which passes through the hollow cavity up and down. Two safety slide bars 14 of different lengths are movably inserted in the cavity. A snap lock body 19 is fixed to the end of the safety slide bar 14. A retaining ring 16 is fixed to the middle of the safety slide bar 14. The retaining ring 16 is supported by a spring 18. The other end of the spring 18 is against the glass frame 12. The spring 18 pushes the safety slide bar 14 outward. When the glass frame 12 is closed, the snap lock body 19 is against the inner wall of the window frame 10 and compresses the spring 18.

[0021] Preferably, an arc surface 20 is provided at the end of the snap lock body 19, and a semicircular bayonet 22 for inserting the snap lock body 19 is provided on the upper and lower inner walls of the window frame 10. After the snap lock body 19 is inserted into the semicircular bayonet 22, the glass frame 12 can be set, and then the upper, middle and lower three-point fixation is achieved on the movable side of the glass frame 12, which effectively improves the closing strength and sealing performance.

[0022] Preferably, a slot 13 is provided on the indoor side of the glass frame 12, and a paddle 17 is fixedly provided at the other end of the safety slide bar 14 and exposed in the slot 13. The paddle 17 is unlocked by pressing the paddles 17 to bring them close to each other, and then the glass frame 12 can be opened by turning the hand-twisted lock handle 11. Compared with the traditional single hand-twisted lock handle 11, this design has better anti-accidental touch and protection effect on children.

[0023] Preferably, in order to facilitate the extension and retraction of the safety slide bar 14, a guide slope 23 pointing to the semicircular bayonet 22 is provided on the outer side of the window frame 10. The oblique guiding effect of the guide slope 23 makes the safety slide bar 14 extend and retract more smoothly.

[0024] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention is not limited to the embodiments described in the specific implementation methods. Any other implementation methods derived by those skilled in the art based on the technical solution of the present invention also fall within the scope of protection of the present invention.
