Description

Technical Field

[0001] The utility model relates to the field of hardware door and window fittings, and particularly relates to a door and window corner protector for preventing accidental contact. Background Art

[0002] The corner protector is one of the common hardware fittings for doors and windows, and is used to connect other hardware fittings on two sides of the window sash to realize the linkage of the door and window hardware system, and complete the inward opening and downward tilting opening mode of the window sash. It is a relatively common door and window hardware fitting, which is installed at the corner of the upper end of the door and window sash profile. Generally, it is L-shaped, and its two ends are respectively connected to the first connectors in the horizontal and vertical directions. At the same time, a corner connecting strip that can slide horizontally and vertically is installed inside it to cooperate with other door and window hardware fittings to realize the transmission function, and then realize the opening and closing of the door and window.

[0003] The publication number is: CN204283109U discloses a door and window corner protector, which includes: a seat body, in an "L" shape; a through groove is provided on the seat body, which is arranged along the extending direction of the L-shaped seat body and is in an "L" shape; a first sliding groove extends along one end of the seat body and connects to the end of the through groove; a second sliding groove extends along the other end of the seat body and connects to the other end of the through groove; a first connector is slidably connected to the first sliding groove; a second first connector is slidably connected to the second sliding groove; a spring piece is arranged in the through groove and slides along the through groove, and its two ends are respectively connected to the first connector and the second first connector; and a pushing member is arranged on the seat body, and the pushing member abuts against the profile, and pushes the seat body to fit against the opposite surface of the profile. For the above-mentioned door and window corner protector, the pushing member is used to abut against the profile, and the seat body is pushed in the opposite direction to tightly fit against the other surface of the profile, and is clamped in the profile by using the frictional force, and the fixation can be realized without damaging the profile structure.

[0004] At present, there are many opening methods for doors and windows on the market, such as inward opening and inward tilting opening. As the transmission part in the door and window system, the above-mentioned door and window corner protector does not have a protection measure when the window sash is in the open state. When the window sash is in the inward opening state and the window handle is accidentally rotated to the inward tilting state again, since one end of the window sash is in the open state, it will cause the window sash to fall, resulting in certain safety hazards. Therefore, the corner protector needs an improved structure to prevent the state of the door and window from changing again when it is in the open state. Summary of the Invention

[0005] The technical problem to be solved by the utility model is to provide a door and window corner protector for preventing accidental contact in view of the above-mentioned deficiencies of the prior art.

[0006] To achieve the above object, the utility model provides the following technical solution. An anti-misoperation window and door corner device includes an L-shaped seat body and a first connecting piece. The first connecting piece is slidably installed on the L-shaped seat body. It is characterized in that: the first connecting piece includes a sliding end slidably connected to the L-shaped base. The surface of the sliding end is provided with a first convex block and a second convex block. The L-shaped seat body is provided with a rotating piece on one side facing the sliding end that can be linked with the window sash. A reset mechanism is further provided between the rotating piece and the L-shaped seat body. The rotating piece is provided with an abutting block on one side facing the first convex block and the second convex block; when the door and window are in the closed state, the window frame drives the rotating piece to make the abutting block away from the first convex block and the second convex block, and the first connecting piece can slide normally; when the door and window are in the open state, the reset mechanism drives the rotating piece to make the abutting block located between the first convex block and the second convex block, and the abutting block abuts against the first convex block and the second convex block to limit the sliding of the first connecting piece.

[0007] By adopting the above technical solution, a first convex block and a second convex block provided on the first connecting piece, an abutting block and a reset mechanism provided on the rotating piece form an anti-misoperation device. When closing the door and window, the window frame drives the rotating piece to rotate, and the abutting block on the rotating piece moves away from the first convex block and the second convex block. At this time, the first connecting piece can slide normally to realize different opening states of the door and window; when the door and window are opened, the reset mechanism drives the rotating piece to make the abutting block located between the first convex block and the second convex block, and the abutting block abuts against the first convex block and the second convex block to limit the sliding of the first connecting piece, so as to prevent the door and window from being linked to change the state, ensuring that the door and window will not fall due to misoperation during opening, reducing the accidental risk of the door and window, and making the door and window system more stable and reliable.

[0008] The above anti-misoperation window and door corner device can be further set as: the reset mechanism includes a reset block provided on the top of the L-shaped seat body. The rotating piece is provided with a receiving groove for installing the reset block on one side facing the L-shaped seat body. Both ends of the receiving groove are provided with embedded grooves for embedding and installing elastic members, and the receiving groove is communicated with the embedded grooves.

[0009] By adopting the above technical solution, the L-shaped seat body is provided with a reset block installed in the receiving groove of the first connecting piece. During use, the window frame drives the rotating piece to rotate, which drives the reset block to abut against the elastic member. The linkage between the window frame and the rotating piece includes, but is not limited to, installing a pushing block on the window frame. The reset block causes the elastic member to deform. When the window sash is opened, the elasticity of the elastic member causes the reset block to displace for reset. When the window sash is opened, the door and window handle drives the first connecting piece to displace the first convex block and the second convex block. When the rotating piece is reset, the abutting block can be reset between the first convex block and the second convex block to generate abutment.

[0010] The above-mentioned anti-misoperation door and window corner protector can be further configured as follows: The rotating member includes a rotating end and an abutting end. A connecting groove is provided at the rotating end, and a connecting hole is provided at the center of the connecting groove. A connecting pin is provided at the top of the L-shaped seat body. The connecting pin passes through the connecting hole, and a riveting surface for riveting with the connecting groove is provided at the top of the connecting pin.

[0011] With the above technical solution, through the cooperation of the connecting pin and the connecting hole, and the setting of the riveting surface, the assembly process of the rotating member and the L-shaped seat body is greatly simplified, reducing the need for complex tools and long-time fine adjustment, thereby reducing the installation cost and improving the assembly efficiency. When necessary, the rotating member can be rigidly damaged to cancel the anti-misoperation function, thus improving the applicability and reliability of the entire device.

[0012] The above-mentioned anti-misoperation door and window corner protector can be further configured as follows: A limiting block is provided at the upper end of the L-shaped seat body, and a limiting groove is provided on one side of the rotating member facing the L-shaped seat body. The limiting block is placed in the limiting groove to limit the rotation angle of the rotating member.

[0013] With the above technical solution, by setting the limiting block and the limiting groove, the rotation angle of the rotating member can be limited to prevent it from rotating excessively and causing certain damage to the product. At the same time, it can avoid damage to the rotating member caused by the excessive closing of the door and window during use. The limiting block can prevent it from continuing to rotate in the limiting groove, thereby protecting the rotating member from damage.

[0014] The above-mentioned anti-misoperation door and window corner protector can be further configured as follows: An L-shaped through groove is provided in the L-shaped seat body along the extending direction of the L-shaped seat body. A first sliding groove and a second sliding groove are respectively provided at both ends of the L-shaped through groove. The first connecting member is slidably connected to the first sliding groove, a second connecting member is slidably arranged in the second sliding groove, and a spring piece is slidably arranged in the L-shaped through groove.

The rotating piece 5 is provided with an abutting block 6 on one side facing the first convex block 3 and the second convex block 4. When the door and window are in the closed state, the window frame drives the rotating piece 5 to make the abutting block 6 move away from the first convex block 3 and the second convex block 4, and the first connecting piece 2 can slide normally. When the door and window are in the open state, the reset mechanism drives the rotating piece 5 to make the abutting block 6 located between the first convex block 3 and the second convex block 4. The abutting block 6 abuts against the first convex block 3 and the second convex block 4 to limit the sliding of the first connecting piece 2. Through the first convex block 3 and the second convex block 4 provided on the first connecting piece 2 and the abutting block 6 and the reset mechanism provided on the rotating piece 5, an anti-mis-touch device is formed. When closing the door and window, the window frame drives the rotating piece 5 to rotate the rotating piece 5, and the abutting block 6 on the rotating piece 5 moves away from the first convex block 3 and the second convex block 4. At this time, the first connecting piece 2 can slide normally to open the door and window to achieve different opening states;When the door or window is opened, the reset mechanism drives the rotating member 5 to make the abutting block 6 located between the first convex block 3 and the second convex block 4.
