Description

Technical Field

[0001] This utility model relates to the field of sliding window technology, specifically a sliding window with a locking structure. Background Technology

[0002] In the field of building doors and windows, sliding windows are widely used due to their advantages such as large lighting area, convenient opening, and no occupation of indoor space. Traditional sliding windows usually consist of a window frame and a window sash that can slide on the window frame. The window sash slides open and close on the bottom frame of the window frame through pulleys or tracks at the bottom. However, in windy weather, the strong wind force acts on the surface of the window sash, which can easily cause the window sash to sway significantly on the track, and even cause the window sash to collide with the window frame. This frequent swaying and collision not only generates noise and affects the indoor environment, but also accelerates the wear and tear on the contact parts between the window sash and the window frame, seriously affecting the service life of the window sash. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a sliding window with a locking structure, which solves the problem that traditional sliding windows are prone to significant shaking in windy weather, affecting the lifespan of the window sash.

[0004] To achieve the above objectives, this utility model provides a sliding window with a locking structure, including a window frame and two sets of window sashes. The window frame includes a bottom frame, and the two sets of window sashes are movably and staggered on the bottom frame. Movable grooves are provided at the center of the outer inner wall of the bottom frame and on the inner inner wall of the bottom frame. Locking plates are provided in the movable grooves. Locking grooves are provided on the bottom outer wall of the outer window sash and the bottom inner wall of the inner window sash. A driving structure is provided in the movable grooves for external users to operate the locking plates to pass through the movable grooves and engage with adjacent locking grooves when the two sets of window sashes are closed.

[0005] The advantages of adopting the above technical solution are as follows: By setting movable grooves on the inner and outer walls of the bottom frame and configuring locking plates and drive structures within the movable grooves, a reliable mechanical locking connection is formed by the interlocking of the locking grooves at the bottom of the window sashes, which are staggered front and rear, with the locking plates. When the window sashes are closed, the operator can activate the drive structure to allow the locking plates to pass through the movable grooves and embed into the locking grooves, firmly locking the two sets of window sashes to the bottom frame. This effectively limits the lateral swaying and displacement of the window sashes in windy conditions. This structure addresses the shortcomings of traditional sliding windows in terms of insufficient wind resistance. Through the multi-component collaborative locking design, it significantly improves the stability of the window sashes in the closed state, reduces impact wear between the window sashes and the window frame, and extends the overall service life of the sliding window. At the same time, the operation process is uniformly controlled by the drive structure, combining convenience and practicality.

[0006] The present invention further includes: a drive hole is provided on the bottom wall of the movable groove, the drive hole is connected to the outer wall of the bottom frame, the drive structure includes a drive shaft movably disposed in the movable groove, the beginning end of the drive shaft is rotatably connected to the bottom wall of the locking plate, the end of the drive shaft extends out of the drive hole to the outside of the bottom frame and forms a rotating ring for external operators to hold, and the drive shaft is threadedly connected to the drive hole.

[0007] The advantages of adopting the above technical solution are as follows: The drive structure in the above technology uses a drive shaft that is threadedly connected to the drive hole, and the end is designed with a rotating ring. This provides a simple and efficient way to move the locking plate. By rotating the outer rotating ring, the user can drive the drive shaft to move axially through the threaded transmission principle, thereby pushing the locking plate to slide in the movable groove, realizing the insertion or separation with the locking groove. This structure does not require a complex linkage mechanism. Locking and unlocking operations can be completed through basic threaded transmission. This not only reduces manufacturing costs, but also improves the convenience and reliability of use. The self-locking characteristic of the threaded connection can ensure that the locking plate remains stable in the locked state, avoiding accidental unlocking due to wind vibration. While ensuring wind resistance, it also takes into account the simplicity of the structure and the convenience of maintenance.

[0008] The present invention further comprises: a connecting plate at the center of the outer wall of the locking plate; damping blocks on both sides of the connecting plate; a first contact surface formed by a smooth curved surface connecting the top wall of the damping block and the outer wall; a clearance fit between the inner wall of the damping block and the side wall of the connecting plate; a second contact surface formed by a smooth curved surface connecting the inner walls at both ends of the locking groove and the bottom wall of the locking groove; two second contact surfaces corresponding to and fitting together with two first contact surfaces; the damping blocks being made of elastic rubber; and the radial cross-section of the combination of the two damping blocks and the locking plate being trapezoidal.

[0009] The advantages of adopting the above technical solution are: the elastic rubber damping block set on the locking plate and its curved surface contact design with the locking groove can effectively buffer the vibration impact of the window sash under the action of wind. The first contact surface of the damping block fits with the second contact surface of the locking groove to form a flexible connection, which can absorb the slight displacement energy of the window sash caused by wind pressure and reduce the wear caused by rigid collision. At the same time, the combination design of the trapezoidal cross section allows the damping block to form a multi-angle abutment with the groove wall after the locking plate is inserted into the locking groove, thereby enhancing the locking firmness.

[0010] The present invention further comprises: a perforation is provided on the inner wall of the damping block, and a damping spring is movably disposed in the perforation. The beginning end of the damping spring is connected to the inner peripheral wall of the perforation, and the end end of the damping spring is connected to the connecting plate. The damping spring and the connecting plate are arranged perpendicularly to each other.

[0011] The advantages of adopting the above technical solution are: the damping spring is set on the inner wall of the damping block, which further enhances the elastic buffering capacity of the locking structure. The elastic deformation of the spring can adapt to the slight displacement of the window sash under different wind pressures. By stretching or compressing, it absorbs vibration energy and avoids stress concentration caused by rigid contact between the locking plate and the locking groove, thereby preventing the window sash from shaking significantly. When the wind force acts on the window sash, the rubber elasticity of the damping spring and the damping block forms a double buffer, allowing the locking structure to maintain the connection strength while allowing the window sash to have a reasonable range of movement, effectively reducing wear under high-frequency vibration.

[0012] The present invention further includes: an anti-detachment plate on the bottom wall of the damping block, an anti-detachment groove horizontally opened on the outer wall of the locking plate, and two anti-detachment plates slidingly disposed in the anti-detachment groove. The radial cross-sections of the anti-detachment plates and the radial cross-sections of the anti-detachment grooves are both trapezoidal.

[0013] The advantages of adopting the above technical solution are: the trapezoidal fit design of the anti-detachment plate and the anti-detachment groove in the above technology ensures the reliable connection between the damping block and the locking plate during long-term use. The structural characteristics of the trapezoidal cross section can prevent the damping block from axially falling off due to external force, while allowing it to slide within the anti-detachment groove to match its own elastic deformation.

[0014] The present invention is further provided in that: two guide holes are provided on the bottom wall of the movable groove, and guide shafts are provided on the inner walls of both ends of the locking plate. The two guide shafts correspond one-to-one with the two guide holes and are inserted into each other.

[0015] The advantages of adopting the above technical solution are: the matching design of the guide hole and the guide shaft in the above technology provides precise guidance and positioning for the movement of the locking plate, ensuring that the locking plate slides smoothly in the movable groove and avoiding tilting or jamming.
