Description

Technical Field

[0001] The utility model relates to the technical field of window sash guardrails, in particular to a window sash guardrail structure which is convenient to install and disassemble. Background Art

[0002] Existing window sash guardrails are usually fixed directly to the wall. The guardrails are difficult to remove and replace, making it very difficult to repair and replace the window sashes later. In addition, the guardrails fixed to the wall require drilling holes in the wall, which not only damages the wall surface and affects the wall's aesthetics, but also to a certain extent undermines the wall's stress-bearing capacity and takes up a large amount of space. When installing window sashes, home improvement companies sometimes omit the installation of guardrails to save space, which greatly reduces safety performance.

[0003] CN201820387474.X discloses a window sash with a guardrail, comprising an outer frame, glass fixed to the outer frame, and a railing. The railing fixing frame is fixedly connected to the railing, and the railing fixing frame can be detachably fixed to the window outer frame, located outside the glass. The window sash with a guardrail of the utility model has the advantages of easy assembly and disassembly of the railing, small space occupation, and high safety.

[0004] However, in this solution, the guardrail and the frame are detachably connected by bolts, which makes assembly and disassembly inconvenient. Tools are needed to remove multiple bolts to remove the guardrail. It is also not safe enough. When the guardrail is subjected to force, the stress will be concentrated at the bolts. When the stress exceeds the bearing capacity of the bolts, it is easy to be damaged. In addition, the safety of the guardrail will be sharply reduced when the bolts are rusted. Utility Model Content

[0005] The utility model provides a window sash guardrail structure which is convenient to install and disassemble, and solves the shortcomings in the prior art that the guardrail is not convenient to install and disassemble, and multiple bolts need to be removed with tools before the guardrail can be removed; and it is not safe enough. When the guardrail is subjected to force, the stress will be concentrated at the bolts, and it is easy to be damaged after the stress exceeds the bearing capacity of the bolts, and the safety of the guardrail will be sharply reduced after the bolts are rusted.

[0006] The utility model provides the following technical solutions:

[0007] The window sash guardrail structure is convenient for installation and disassembly, comprising a window sash main body, the window sash main body comprising a window frame component and a window sash component; a guard rail is installed on the window frame component, a snap-in groove is provided on the side of the window frame component, and a detachable guard rail is installed in the snap-in groove, wherein the guard rail is fixed with a limited extension on one side and a limited hook is fixed on the other side, and an adjusting bolt is connected to one side of the limit hook by a thread, and the guard rail is pushed to move to one side by the adjusting bolt, and the limited extension and the limit hook both extend into the snap-in grooves on both sides of the window frame component. By providing the snap-in groove and providing the limited extension on one side of the guard rail and the limit hook on the other side, the guard rail can be limited on both sides after moving to one side, and then the guard rail can be limited by pressing the conversion frame by adjusting the bolt, thereby completing the fixing of the guard rail. Compared with fixing by bolts, limiting by the snap-in groove, the limit extension and the limit hook can avoid stress concentration, is safer, and is more convenient to install and disassemble.

[0008] As a further improvement of the above solution.

[0009] Preferably, the window frame component includes an outer frame and a conversion frame, the snap-in grooves on both sides of the conversion frame are set to a T-shaped structure, the cross-sectional shape of the limiting extension is a Z-shaped structure, the cross-sectional shape of the limiting hook is an n-shaped structure, and the Z-shaped structure and the n-shaped structure are both adapted to the T-shaped structure. The snap-in grooves on both sides are symmetrically arranged, so during installation, there is no need to consider which side the adjustment bolts of the guardrail are facing, only one side of the limiting extension needs to be set close to the conversion frame.

[0010] Preferably, the adjusting bolt comprises a screw rod, an adjusting head is mounted on one end of the screw rod, an anti-slip stopper is provided on the peripheral wall of the adjusting head, and the other end of the screw rod is circular.

[0011] Preferably, a limiting groove is provided on the side of the guardrail close to the limiting hook, and a nut is fixed in the limiting groove. The guardrail is limited by the nut and the adjusting bolt. The nut is fixed to the guardrail. When the adjusting bolt rotates, the nut does not rotate, so the adjusting bolt extends or retracts. When the adjusting bolt is extended, it plays a limiting role, so that the guardrail cannot move in the opposite direction of the engagement, thereby completing the fixation of the guardrail. When the adjusting bolt is retracted, the guardrail moves in the opposite direction of the engagement, so that the guardrail can be easily removed.

[0012] Preferably, the snap-in slots are provided on the left and right sides of the window frame component, and the upper and lower sides of the guardrail are adapted to the conversion frame.

[0013] Preferably, the snap-in slots are provided on the left and right sides and the upper side of the window frame component, the left and right sides of the guardrail are provided with limit extensions and limit hooks respectively, and the upper side of the guardrail is provided with a limit hook.

[0014] Preferably, the snap-in grooves are provided on the upper and lower sides of the window frame component, the limit extension is provided on the lower side of the guardrail, and the limit hook and the adjusting bolt are provided on the upper side of the guardrail.

[0015] It should be understood that the above general description and the following detailed description are merely illustrative and do not limit the present invention.

[0016] In the utility model, a snap-in groove is provided, and a limit extension is provided on one side of the guardrail and a limit hook is provided on the other side, so that the guardrail can be limited on both sides after moving to one side, and then the guardrail can be limited by adjusting the bolt against the conversion frame, thereby completing the fixation of the guardrail. Compared with fixing with bolts, limiting by the snap-in groove, the limit extension and the limit hook can avoid stress concentration, is safer, and is more convenient to disassemble and assemble.
