Description
Technical Field
[0001] This utility model belongs to the field of door and window hardware system accessories, specifically relating to an anti-misoperation structure for side-pressure windows. Background Technology
[0002] Side-press windows achieve lateral sealing between the window sash and frame through a multi-point locking mechanism. They are primarily used in building environments with high requirements for airtightness, watertightness, and sound and thermal insulation, offering advantages in overall sealing performance compared to conventional casement windows. Because the sealing function of side-press windows relies on the precise displacement and final compression of the window sash during closing, they demand high installation precision and the rigidity and processing quality of the frame and sash profiles. The hardware system of side-press windows typically requires high-end profiles with regular structures and precise grooves. The hardware system of side-press windows is complex, requiring precise linkage and transmission between multiple components such as the upper pulley assembly, corner assembly, locking point assembly, handle assembly, lower pulley assembly, and center lock assembly. User misoperation can easily lead to component wear, transmission failure, or even damage to the hardware system, affecting the normal service life of the side-press window. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide an anti-misoperation structure for side-pressure windows, which addresses the shortcomings of the existing technology. This anti-misoperation structure enables the side-pressure window to be locked by unlocking first and then transmitting power, thereby eliminating misoperation from the structure and ensuring the transmission accuracy and service life of the side-pressure window hardware system.
[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a lock point assembly and a lock base for preventing accidental locking of side-pressure windows, comprising a lock body, a fixing base, and an anti-accidental locking device. The inner side of the fixing base is fixed to the side of the window sash profile where the handle is installed. A lock hook is fixed to the upper part of the lock body, and the lower part of the lock body is movably inserted through the inner side of the fixing base. The anti-accidental locking device is rotatably installed on the outer side of the fixing base, and a pressure-reducing part is provided on the side of the anti-accidental locking device facing away from the lock body. The anti-misoperation device has a hook part on the side facing the lock body, and a limiting boss is provided on the side of the lock body facing the anti-misoperation device. The lock seat is fixed to the window frame profile, and a sliding groove is provided on the lock seat. A roller is provided in the sliding groove. Before the side-pressure window is locked, the hook part is located directly above the limiting boss. When the side-pressure window is locked by operating the handle, the lock seat presses against the pressing part, which drives the anti-misoperation device to rotate and moves the hook part away from the top of the limiting boss. The lock body can then move upward until the lock hook catches the roller, thereby achieving the locking of the side-pressure window.
[0005] This utility model's anti-misoperation structure for side-pressure windows effectively prevents accidental operation and improves system reliability. Specifically, before the side-pressure window is locked, i.e., when the side-pressure window is open, the hook part is located directly above the limiting boss, acting as a limit to prevent the lock body from moving upwards, thus preventing forced transmission and wear of components due to accidental operation of the handle. When the side-pressure window needs to be closed, during the process of locking the side-pressure window by operating the handle, the anti-misoperation device moves horizontally to contact the lock seat. Utilizing the lever principle, the lock seat first presses against the pressing part of the anti-misoperation device, causing the anti-misoperation device to rotate and drive the hook part away from above the limiting boss. At this point, the lock body can move upwards under the drive of the handle until the lock hook engages the roller, thereby locking the side-pressure window. This utility model's anti-misoperation structure for side-pressure windows, through the innovative structural design of the locking point assembly and lock seat, achieves a side-pressure window locking method of unlocking first and then transmission, structurally eliminating accidental operation and ensuring the transmission accuracy and service life of the side-pressure window hardware system.
[0006] Preferably, the anti-misoperation device is rotatably mounted on the outside of the fixed base via a pin. A return spring is connected between the lower part of the anti-misoperation device and the fixed base. The hook part is located at the top of the anti-misoperation device, and the pressing part is located at the bottom of the anti-misoperation device. The anti-misoperation device is installed via a pin and a return spring, resulting in a simple structure that enables automatic reset and buffering, further improving the reliability and service life of the hardware system.
[0007] As a further preferred embodiment, the front end of the top pressure section is threaded with an adjusting screw. The adjusting screw allows adjustment of the activation distance of the anti-misoperation device, ensuring the transmission accuracy of the hardware system. During the side-pressure window locking process, the adjusting screw, as an extension of the top pressure section, directly contacts the lock seat, and the lock seat rotates the anti-misoperation device by pressing the adjusting screw.
[0008] As a further preferred embodiment, the top of the slide rail is a narrow groove that narrows towards the interior, and a rivet is threadedly connected to the top of the lock body. During the locking of the side-pressure window, the head of the rivet extends into the slide rail, guiding the upward movement of the lock body and limiting its upward travel. The aforementioned eccentric rivet, in conjunction with the slide rail and the narrow groove at its top, facilitates the movement of the side-pressure window towards the interior, achieving a good side-pressure sealing effect. When it is necessary to open the side-pressure window, the combined design of the eccentric rivet, slide rail, and narrow groove helps the side-pressure window move towards the exterior, completing the unlocking process.
[0009] As a further preferred option, the rivet is an eccentric rivet. The eccentric rivet design helps to improve the fitting accuracy between the locking point assembly and the locking seat, ensuring a side-pressure sealing effect.
[0010] Compared with existing technologies, this utility model has the following advantages: The anti-misoperation structure for side-pressure windows of this utility model, through the innovative structural design of the locking point assembly and lock seat, achieves a side-pressure window locking method of unlocking first and then transmission, structurally eliminating misoperation and ensuring the transmission accuracy and service life of the side-pressure window hardware system. Specifically, before the side-pressure window is locked, i.e., in the open state, the hook part is located directly above the limiting boss, acting as a limit to prevent the lock body from moving upwards, thereby preventing forced transmission and wear of components due to misoperation of the handle. When the side-pressure window needs to be closed, during the process of locking the side-pressure window by operating the handle, the anti-misoperation device moves horizontally to contact the lock seat. Utilizing the lever principle, the lock seat first presses against the pressing part of the anti-misoperation device, causing the anti-misoperation device to rotate and drive the hook part away from above the limiting boss. At this time, the lock body can then move upwards under the drive of the handle until the lock hook catches the roller, thereby achieving the locking of the side-pressure window.

[0012] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Any devices or components not limited in this invention employ conventional techniques in the art.
[0013] The side-pressure window anti-misoperation structure of the embodiment is applied to Figure 1 The diagram illustrates a side-pressure window hardware system. This system includes an upper pulley assembly 1, a corner assembly 2, a locking point assembly 3, a handle assembly 4, a lower pulley assembly 5, and a center lock assembly 6, all connected via a transmission rod. There are two sets of each of the upper pulley assembly 1, locking point assembly 3, lower pulley assembly 5, and center lock assembly 6. There are three sets of the corner assembly 2, and one set of the handle assembly 4. The upper pulley assembly 1 and lower pulley assembly 5 are respectively installed on the upper and lower sides of the window sash profile 71. The corner assembly 2 is installed at the corner of the window sash profile 71. The handle assembly 4 includes a handle (not shown) and a lock box 41. The locking point assembly 3 and handle assembly 4 are installed on one side of the window sash profile 71, and the center lock assembly 6 is installed on the other side of the window sash profile 71.
[0014] like Figures 2-6 As shown, the anti-misoperation structure for the side-pressure window in this embodiment includes a locking point assembly 3 and a lock base 30. The locking point assembly 3 includes a lock body 31, a fixing base 32, and an anti-misoperation device 33. The inner side of the fixing base 32 is fixed to the side of the window sash profile 71 where the handle is installed. A lock hook 311 is fixed to the upper part of the lock body 31, and the lower part of the lock body 31 is movably inserted through the inner side of the fixing base 32. The anti-misoperation device 33 is rotatably installed on the outer side of the fixing base 32, with the anti-misoperation device 33 facing away from the lock body. A pressing part 331 is provided on one side of the lock body 31, a hook part 332 is provided on the side of the anti-misoperation device 33 facing the lock body 31, an eccentric rivet 312 is threaded on the top of the lock body 31, a limiting boss 313 is provided on the side of the lock body 31 facing the anti-misoperation device 33, the lock seat 30 is fixed to the window frame profile 72, a sliding groove 301 is provided on the lock seat 30, the top of the sliding groove 301 is a narrow groove 302 that narrows towards the interior, and a roller 303 is provided in the sliding groove 301.
[0015] Specifically, the anti-misoperation device 33 is rotatably mounted on the outside of the fixed base 32 via a pin 333. A return spring 334 is connected between the lower part of the anti-misoperation device 33 and the fixed base 32. The hook part 332 is located on the top of the anti-misoperation device 33, and the pressing part 331 is located on the bottom of the anti-misoperation device 33. An adjusting screw 335 is threadedly connected to the front end of the pressing part 331.
[0016] The working principle of the anti-misoperation structure for the side-pressure window in the above embodiment: Before the side-pressure window is locked, that is, in the open state of the side-pressure window, the hook part 332 is located directly above the limiting boss 313, such as Figure 3 As shown, it serves as a limit switch to prevent the lock body 31 from moving upwards; when it is necessary to close the side window, during the process of locking the side window by operating the handle, the anti-misoperation device 33 gradually moves horizontally towards the lock seat 30, and after the adjusting screw 335 contacts the lock seat 30, as shown... Figure 4As shown, the anti-misoperation device 33 continues to move horizontally, and the head of the eccentric rivet 312 extends into the slide groove 301. At the same time, using the lever principle, the lock seat 30 first presses against the adjusting screw 335 of the anti-misoperation device 33, as... Figure 5 As shown, after the anti-misoperation device 33 rotates and drives the hook part 332 to move away from above the limiting boss 313, the lock body 31 can then move upward under the drive of the handle until the lock hook 311 hooks the roller 303, as shown. Figure 6 As shown, this achieves the locking of the side-pressure window. During the upward movement of the lock body 31, the head of the eccentric rivet 312 guides the upward movement of the lock body 31 and limits its upward travel. The above-described locking process of the side-pressure window realizes a locking method of unlocking first and then transmission, eliminating misoperation from the hardware system structure and ensuring the transmission accuracy and service life of the side-pressure window hardware system.
