Description

Technical Field

[0001] The utility model relates to the field of window openers, in particular to a quick disassembly and assembly mechanism of a sliding door push-pull device. Background Art

[0002] Sliding doors are a type of door and window that we often encounter and use in our daily lives. Most of them are electric. They mainly use a linkage device to slide the main body of the movable door and window onto the slide rail of the door and window frame body. The linkage device mainly includes a motor, a transmission module, and a pulley component module. The transmission module is mainly linked to the motor, and the motor drives the pulley component module through the transmission module to link with the movable door and window frame, thereby realizing the opening and closing of the movable door and window.

[0003] The existing utility model patent with publication number CN220336715U discloses an electric trackless push-pull device, including a driving component, a driven component, a transmission belt wound between the driving component and the driven component, and a door and window connecting member arranged on the transmission belt and moving back and forth between the driving component and the driven component along the transmission belt. One end of the door and window connecting member is connected to a working surface on one side of the transmission belt, and the other end is provided with a mounting seat for connecting with the movable door and window. The transmission belt is provided with at least one limiter for limiting the rotation stroke of the transmission belt. The movable door and window can be directly moved along the track in the door and window frame by the motor. In this way, the push-pull device does not need to be equipped with an additional track, and only the existing door and window track can be used to achieve switch control. While reducing the difficulty of installation, the pulley component in the original technology is simplified, so that only a sheet-shaped door and window connecting member is needed to conveniently drive the movable door and window to open and close, thereby reducing the cost. For example, the patent Figure 5 As shown, in the push-pull device, one end of the door and window connector is fixedly connected to the synchronous belt, and the other end is fixedly connected to the door leaf by screws, and then the synchronous belt is driven by the motor to rotate to realize the opening and closing of the sliding door. However, there are still some problems in actual use. First, the connection process between the door and window connector and the door and window is still relatively cumbersome, which requires a lot of time and manpower. During the installation process, the door and window connector needs to be accurately positioned and fixed with fasteners such as screws, which not only increases the difficulty of installation, but also affects the efficiency of installation. Secondly, when the sliding door or push-pull device needs to be disassembled for maintenance or replacement, the disassembly process is also inconvenient. Since the door and window connector and the window leaf are fixed by fasteners such as screws, these fasteners need to be released first when disassembling, which undoubtedly increases the difficulty and time cost of disassembly. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a quick disassembly and assembly mechanism of a sliding door push-pull device in view of the deficiencies of the above-mentioned prior art.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a quick disassembly and assembly mechanism of a sliding door push-pull device, comprising a push-pull connecting member and a door leaf mounting seat respectively used to connect with a door frame and a door leaf, characterized in that: a disassembly plate is provided at one end of the push-pull connecting member corresponding to the door leaf mounting seat, a locking cavity for partially accommodating the disassembly plate is opened on the door leaf mounting seat, a locking cover plate is provided on the surface of the door leaf mounting seat, a protrusion and a groove corresponding to each other are provided between the locking cover plate and the disassembly plate, a locking mechanism is provided on the locking cover plate, the locking cover plate can move relative to the door leaf mounting seat, and the locking cover plate partially covers the locking cavity through the locking mechanism, and the disassembly plate can be separated from the locking cavity by driving the locking cover plate so that the protrusion corresponds to the groove, and when the protrusion and the groove are misaligned with each other, the disassembly plate is restricted in the locking cavity by the locking cover plate.

[0006] By adopting the above technical solution, the correspondence or misalignment of the protrusion and the groove is achieved by moving the locking cover plate, and this movement can be opening and closing or sliding. When disassembly is required, the locking cover plate is manually operated to move it so that the protrusion corresponds to the groove. At this time, the disassembly plate can be removed from the locking cavity. When installation is required, the disassembly plate is placed in the locking cavity, and then the locking cover plate is released. The locking mechanism resets the locking cover plate, and the protrusion is misaligned with the groove, thereby fixing the disassembly plate. The design simplifies the connection and disassembly process between the sliding door and the door frame, improves the disassembly efficiency, and realizes the quick locking and unlocking function through the cooperation of the protrusion and the groove and the action of the locking mechanism. The operation is convenient, safe and reliable, and convenient for later maintenance.

[0007] The above-mentioned quick disassembly and assembly mechanism of a sliding door push-pull device can be further configured as follows: a clearance groove for the disassembly and assembly plate to pass through is opened on the locking cover plate, and the grooves are provided on both sides of the disassembly and assembly plate, and the two ends of the clearance groove corresponding to the disassembly and assembly plate are provided with protrusions adapted to the grooves, and the protrusions slide along the surface of the door leaf mounting seat, so that the protrusions and the grooves are arranged opposite to or staggered, and through the locking mechanism, the locking cover plate maintains the staggered state of the protrusions and the grooves under normal conditions.

[0008] The above technical solution is adopted, by setting the clearance groove, covering most of it, changing it into a convex lock, and limiting it to a sliding mode. When it needs to be disassembled, the convex slides along the surface of the door leaf mounting seat by operating the locking cover plate until it corresponds to the groove on the disassembly plate, and the disassembly plate can be removed from the clearance groove. When installing, put the disassembly plate into the clearance groove, release the locking cover plate, and the locking mechanism resets the locking cover plate, and the convex and the groove are misaligned, thereby fixing the disassembly plate. Through the cooperation of the clearance groove and the convex, the disassembly plate is quickly locked and unlocked. The locking mechanism ensures that when there is no external force, the locking cover plate maintains the misaligned state of the convex and the groove, thereby maintaining the stability of the connection.

[0009] The above-mentioned quick disassembly and assembly mechanism of the sliding door push-pull device can be further configured as follows: a movable slide groove arranged along the sliding direction of the locking cover plate and a limit lock pin arranged in the movable slide groove to limit the sliding distance of the locking cover plate are provided between the locking cover plate and the door leaf mounting seat.

[0010] By adopting the above technical solution, the movable slide groove provides a guide for the sliding of the locking cover plate to ensure that it moves along a predetermined trajectory, and the limit lock pin limits the sliding distance of the locking cover plate to prevent it from sliding out of the movable slide groove or sliding out of position, so that the two ends of the movable slide groove correspond to the misaligned state and corresponding state of the protrusion and the groove respectively, thereby achieving stable locking and unlocking, ensuring the stability and accuracy of the locking cover plate during the sliding process, preventing disassembly and assembly failure due to excessive sliding or out of position, and improving stability.

[0011] The above-mentioned quick disassembly and assembly mechanism of the sliding door push-pull device can be further configured as follows: the disassembly and assembly plate has a surface with a groove with a stop protrusion extending upward, and when the disassembly and assembly plate is arranged in the locking cavity, the stop protrusion is normally against the inner wall of the clearance groove.

[0012] By adopting the above technical solution, the counteraction between the stop protrusion and the inner wall of the give way groove provides an additional support point for the disassembly plate, increases its stability in the locked state, and at the same time realizes the limiting of the locked state. The design of the stop protrusion enhances the stability of the disassembly plate in the locked state and prevents accidental loosening or falling off due to external force.

[0013] The above-mentioned quick disassembly and assembly mechanism of the sliding door push-pull device can be further configured as follows: the locking cover plate is bent outward to form a manual operating block.

[0014] By adopting the above technical solution, the manual operation block provides an operation point for the operator, and the locking cover plate can be driven to move through simple manual operation to achieve locking and unlocking of the disassembly and assembly plate.

[0015] The above-mentioned quick disassembly and assembly mechanism of the sliding door push-pull device can be further configured as follows: the locking cavity is a square cavity, and the corners at both ends of the give way groove are provided with limiting angle blocks, and the limiting angle blocks move with the locking cover plate, thereby approaching or moving away from the locking cavity.

[0016] By adopting the above technical solution, the design of the square cavity enables the disassembly plate to be accurately aligned when placed in the locking cavity, and the limit angle block moves closer to or away from the locking cavity as the locking cover plate moves, further ensuring the stability and positioning accuracy of the disassembly plate in the locked state, and preventing installation or unlocking failure due to position deviation.

[0017] The above-mentioned quick disassembly and assembly mechanism of the sliding door push-pull device can be further configured as follows: the locking mechanism includes a spring or tension spring arranged between the locking cover plate and the door leaf mounting seat, one end of the spring or tension spring is connected to the locking cover plate, and the other end is connected to the door leaf mounting seat.

[0018] With the above technical solution, the locking mechanism adopts a spring or tension spring design, one end of which is connected to the locking cover plate, and the other end is connected to the door leaf mounting seat. When the locking cover plate is moved by external force, the spring or tension spring will deform; when the external force disappears, the spring or tension spring will return to its original state, thereby driving the locking cover plate back to the initial position, that is, the state where the protrusion and the groove are misaligned.

[0019] The above-mentioned quick disassembly and assembly mechanism of a sliding door push-pull device can be further configured as follows: the push-pull connecting part includes a belt buckle connected to the synchronous belt, a belt buckle plate and a fastener connecting the belt buckle and the belt buckle plate, the inner wall of the belt buckle is provided with teeth, and cooperates with the belt buckle plate to form a belt installation cavity for fixing the synchronous belt, the belt buckle plate is arranged between the belt buckle and the disassembly and assembly plate, and is fixed by fasteners.

[0020] By adopting the above technical solution, the inner wall of the belt buckle is provided with teeth, which cooperate with the belt buckle plate to form a belt installation cavity for fixing the synchronous belt. The belt buckle plate and the disassembly plate are connected together by fasteners, thereby realizing a stable connection between the push-pull connector and the disassembly plate.

[0021] The above-mentioned quick disassembly and assembly mechanism of a sliding door push-pull device can be further configured as follows: a connecting end of the disassembly and assembly plate and the push-pull connecting piece is provided with a plurality of axially arranged height adjustment grooves, and an adjusting bolt is provided in the height adjustment groove. After passing through the height adjustment groove, the adjusting bolt is fixedly connected to the push-pull connecting piece, and the disassembly and assembly plate can slide up and down along the adjusting bolt.

[0022] With the above technical solution, the cooperation between the height adjustment slide groove and the adjustment bolt allows the disassembly plate to slide up and down along the adjustment bolt, thereby adjusting the relative height between the disassembly plate and the push-pull connector. This design is suitable for sliding doors with different installation positions and height requirements.

[0023] The above-mentioned quick disassembly and assembly mechanism of the sliding door push-pull device can be further configured as follows: the surface of the disassembly and assembly plate is provided with a plurality of axially arranged height adjustment slots, the fastener is an adjustment bolt, the adjustment bolt passes through the height adjustment slot and is fixedly connected to the belt buckle plate and the belt buckle, and the disassembly and assembly plate can slide up and down along the adjustment bolt

[0024] By adopting the above technical solution, the height adjustment groove on the surface of the disassembly plate cooperates with the adjusting bolt (fastener), so that the disassembly plate can slide up and down along the adjusting bolt, thereby adjusting it with the belt buckle plate and the belt.

The limit angle blocks 43 move with the locking cover plate 4 to approach or move away from the locking cavity 21. Grooves 31 are provided on both sides of the disassembly and assembly plate 3. The two ends of the corresponding disassembly and assembly plate 3 are provided with protrusions 42 adapted to the grooves 31, and the protrusions 42 slide along the surface of the door leaf mounting seat 2, so that the protrusions 42 and the grooves 31 are arranged opposite or offset, and the locking cover plate 4 can slide horizontally relative to the door leaf mounting seat 2, and a tension spring 5 is provided between the locking cover plate 4 and the door leaf mounting seat 2, one end of the tension spring 5 is connected to the locking cover plate 4, and the other end is connected to the door leaf mounting seat 2, so that under normal conditions, the protrusion 42 and the groove 31 are in an offset state, and the locking cover plate 4 is partially covered with the locking cavity 21 through the tension spring 5, and the disassembly and assembly plate 3 can be separated from the locking cavity 21 by driving the locking cover plate 4 so that the protrusion 42 corresponds to the groove 31, and when the protrusion 42 and the groove 31 are offset from each other, the disassembly and assembly plate 3 is restricted in the locking cavity 21 by the locking cover plate 4, thereby realizing the synchronous connection between the synchronous belt A and the door leaf B.

[0032] like Figure 1-Figure 3As shown, a limit lock pin 22 is provided on the door leaf mounting seat 2, and a movable slide groove 44 for accommodating the limit lock pin 22 is provided on the locking cover plate 4. The movable slide groove 44 is set to a long strip shape along the sliding direction of the locking cover plate, and the two ends correspond to the locked state and the unlocked state respectively. The pin cap at the end of the limit lock pin 22 covers the movable slide groove 44 to limit the surface of the door leaf mounting seat 2 and the locking cover plate 4 to fit. The disassembly plate 3 has a surface with a groove 31 and a stop protrusion 32 extending upward.

At this time, the disassembly plate 3 can be directly taken out from the locking cavity 21 through the give way groove 41 to achieve separation, and automatically reset after release.
