Description

Technical Field

[0001] This utility model relates to the field of door and window technology, specifically a quick-installation structure for door leaf guide rails. Background Technology

[0002] With the continuous development of the construction industry and home decoration, people have placed higher demands on the functionality, space utilization, and aesthetics of door panels. PD doors (also known as PT doors, which combine the advantages of both hinged and sliding opening methods) are increasingly favored by the market due to their flexibility, convenience, and space-saving characteristics. The design concept of PD doors originated in Singapore, and its essence is a door system that cleverly combines the functions of hinged and sliding doors.

[0003] A typical PD door structure usually includes a door frame, sliding panels, hinged panels, overhead rails, and related hardware. Among these, the overhead rails are the key component ensuring smooth movement and transitions of the sliding panels. In existing technology, the overhead rail system of a PD door typically consists of two parts: one part is fixed to the door frame, its length and width matching the sliding panels; the other part is fixed to the top of the hinged panels. When the PD door is in the sliding position, the movement trajectory of the sliding panels depends on the precise connection and coordination of these two separate overhead rail sections.

[0004] However, the segmented design of this existing PD door track has significant drawbacks and challenges in actual installation and later use: 1. Extremely high installation precision requirements: To ensure that the sliding door does not jam, bounce, or make abnormal noises during movement, the hanging rails fixed to the door frame and the top of the casement door must be perfectly parallel during installation, and the ends of the two rails must be seamless and flush. This means that installers need to have extremely sophisticated measurement, positioning, and adjustment skills; any slight angular deviation or height inconsistency may lead to serious consequences. 2. The installation process is complex and time-consuming: Due to the high dependence on installation accuracy, installers need to spend a lot of time and energy on-site for repeated measurements, trial installations, and fine-tuning. This greatly increases the difficulty and time cost of construction, and reduces installation efficiency. Especially in large-scale projects, this inefficiency can lead to huge economic losses.

[0005] 3. Poor user experience and potential damage: If the mounting rails are not perfectly aligned, the sliding fan will experience problems such as uneven operation, jamming, and increased friction when passing over the rail connections. Over time, this not only severely impacts the user experience but may also accelerate the wear and tear on the mounting rails, the sliding fan, and related hardware, potentially leading to component damage, shortening the product's lifespan, and incurring additional maintenance and repair costs. Therefore, further improvements are necessary. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of existing technologies and provide a quick-installation structure for door leaf guide rails that is simple in structure, low in manufacturing cost, convenient and quick to install, highly efficient in installation, and stable in use.

[0007] The purpose of this utility model is achieved in the following way: a quick installation structure for a door leaf guide rail, which includes a guide rail body, and a recessed snap-fit ​​groove is provided at the upper end of the guide rail body. It also includes a mounting base, and a front baffle extends upward from the top front end of the mounting base. The front baffle is hooked onto the front surface of the door frame to restrict the installation position of the front baffle. The bottom of the mounting base extends downward and is provided with a buckling device. After the mounting base is positioned and installed with the door frame, the buckling groove of the guide rail body engages with the buckling device, thereby fixing the guide rail body to the door frame.

[0008] Furthermore, the buckle groove has an anti-detachment protrusion extending inward from the groove opening.

[0009] Furthermore, a decorative panel extends upward from the front end of the guide rail body. After the guide rail body is connected to the mounting base, the decorative panel covers the front of the front baffle.

[0010] Furthermore, the buckling device consists of a first elastic arm and a second elastic arm symmetrically arranged below the mounting base, and the first elastic arm and the second elastic arm are provided with guide protrusions facing the groove wall of the buckling groove.

[0011] Furthermore, the guide boss has inclined guide surfaces on its upper and lower sides.

[0012] Furthermore, the guide rail body is provided with several auxiliary mounting holes.

[0013] Furthermore, the mounting base, the first elastic arm, the second elastic arm, and the guide boss are integrally manufactured from profiles.

[0014] Furthermore, the mounting base is provided with several positioning mounting holes, and the fixing screws pass through the positioning mounting holes to connect with the door frame.

[0015] The beneficial effects of this utility model are: 1. Simple structure, low manufacturing cost, and improved market competitiveness.

[0016] This invention utilizes a front baffle extending upwards from the top front end of the mounting base to hook onto the front face of the door frame. Since the front face of the door frame serves as a stable and readily available reference plane, the hooking action of the front baffle effectively restricts the installation position of the mounting base.

[0017] Once the guide rail body and the mounting base are connected by snap-fit ​​or other means, the installation position of the guide rail body can be accurately limited, eliminating the need for extensive repeated calibration.

[0018] This utility model uses a snap-fit ​​method to fix the guide rail body to the mounting base, and connects it to the door frame through the positioning mounting holes on the mounting base, supplemented by auxiliary mounting holes on the guide rail body, making the entire installation process faster and simpler.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings. A quick-installation structure for a door leaf guide rail includes a guide rail body 1, the upper end of which has a recessed snap-fit ​​groove 2; it also includes a mounting base 3, the top front end of which is further provided with a front baffle 6, which is hooked onto the front end face of the door frame 4 to restrict the installation position of the front baffle; the bottom of the mounting base is provided with a snap-fit ​​device extending downward, after the mounting base is positioned and installed with the door frame, the snap-fit ​​groove of the guide rail body engages with the snap-fit ​​device, thereby fixing the guide rail body to the door frame.

[0027] In this embodiment: During installation, the mounting base 3 is first placed on the door frame 4, and its top front end plate 6 is precisely hooked and rests against the front surface of the door frame 4. Since the front surface of the door frame is the end face of the cabinet panel, its parallelism is relatively standard, thus serving as the reference surface for PD door installation. This hooking method allows the mounting base 3 to quickly and accurately achieve initial horizontal and vertical positioning, thereby limiting its installation position on the door frame. Once the mounting base 3 is fixed to the door frame, the guide rail body 1 can quickly engage with the hooking device at the bottom of the mounting base 3 using its snap-fit ​​groove 2. Through this snap-fit ​​engagement, the guide rail body 1 is firmly fixed to the precisely positioned mounting base 3, thereby achieving a quick and precise fixed connection between the guide rail body 1 and the door frame 4.

[0028] The design of the front baffle 6 hook on the front face of the door frame utilizes the existing plane of the door frame as a reliable reference, realizing the rapid self-alignment and precise positioning of the mounting base, which greatly reduces the installation difficulty and the skill requirements of the installers.

[0029] In one embodiment: the slot of the buckle groove 2 has an anti-detachment protrusion 5 extending inward from the slot opening.

[0030] In this embodiment: when the latching groove 2 of the guide rail body 1 engages with the latching device of the mounting base 3, the anti-detachment protrusion 5 forms an obstacle or restriction at the groove opening after the latching device is fully inserted into the latching groove. This prevents the latching device from easily disengaging from the latching groove, requiring specific external force or specific operation to release the engagement. This effectively prevents the guide rail body from detaching from the mounting base due to vibration, impact, or accidental external force during long-term use, greatly improving the stability and safety of the entire installation structure. It ensures that the guide rail remains connected during door operation, avoiding door malfunctions or safety hazards caused by guide rail detachment.

[0031] In one embodiment, a decorative panel 11 extends upward from the front end of the guide rail body 1. After the guide rail body 1 is connected to the mounting base 3, the decorative panel 11 covers the front of the front baffle 6. When the guide rail body 1 is connected and fixed to the mounting base 3 via a snap-fit ​​device, the decorative panel 11 will naturally be located outside the front baffle 6 of the mounting base 3, concealing it. This effectively hides the functional components such as the front baffle of the mounting base, making the exterior of the installation structure neater and more aesthetically pleasing, and improving the overall visual effect of the door system.

[0032] In one embodiment: the buckling device consists of a first elastic arm 7 and a second elastic arm 8 symmetrically arranged below the mounting base 3, and the first elastic arm 7 and the second elastic arm 8 are provided with guide protrusions 9 facing the groove wall of the buckling groove 2.

[0033] When the guide rail body 1 is pushed towards the mounting base 3 for engagement, the inner wall of the locking groove 2 of the guide rail body will contact the guide boss 9 on the elastic arm. Due to the elastic deformation capability of the elastic arm, it will bend and contract inward under the action of force, allowing the guide rail body to continue to fall. Once the guide boss 9 passes through the narrowest point of the locking groove 2, the elastic arm will open outward by its own elastic force, causing the guide boss 9 to engage in a specific position in the locking groove, forming a stable engagement.

[0034] In this embodiment, the guide boss 9 plays a guiding role during the snap-fit ​​process, which helps to accurately align the guide rail body with the mounting base and simplifies the installation operation. At the same time, the symmetrically arranged elastic arms can more evenly distribute the snap-fit ​​stress and enhance the stability of the connection.

[0035] In this embodiment, the guide boss 9 has inclined guide surfaces 91 on its upper and lower sides. When the guide rail body 1 is engaged with the mounting base 3, the inner wall of the snap-fit ​​groove 2 first contacts the inclined guide surfaces 91 of the guide boss 9. These inclined surfaces can decompose the vertical thrust into a horizontal component, smoothly guiding the elastic arm to bend inward. Similarly, after the snap-fit ​​is fully engaged, the inclined surfaces also help guide the elastic arm to smoothly engage.

[0036] In one embodiment, the guide rail body 1 has several auxiliary mounting holes 10. After positioning and installation, or when it needs to withstand greater loads, greater environmental vibrations, or when the user wants to add double protection, the guide rail body 1 can be directly fixed to the door frame 4 or other support structure through these holes using screws or other fasteners.

[0037] In one embodiment, the mounting base 3, the first elastic arm 7, the second elastic arm 8, and the guide boss 9 are integrally formed from profiles. This integral molding avoids assembly errors, ensures precise matching of geometric dimensions between components, and improves product quality.

[0038] In one embodiment: the mounting base 3 has a plurality of positioning mounting holes 31, and the fixing screw passes through the positioning mounting holes 31 to connect with the door frame 4.

[0039] After the mounting base 3 is initially positioned by the front baffle 6, it can be firmly anchored to the door frame 4 using screws or other fasteners through these positioning mounting holes 31, forming a stable base to support the weight of the subsequent guide rail body and the operating load.

[0040] In summary, this utility model provides a highly efficient, precise, and user-friendly quick-installation structure for door leaf guide rails. Its core lies in utilizing the existing structure of the door frame as the installation benchmark and achieving rapid positioning and fixing of the guide rail through a clever snap-fit ​​design. Specifically, it consists of the following steps.

[0041] 1. Base Positioning and Mounting Base Fixing: The installation process begins with the positioning of mounting base 3. The user aligns mounting base 3 with the installation position on the door frame 4. The front baffle 6, extending upwards from the top front end of mounting base 3, will naturally hook onto the front surface of the door frame 4. This "hooking" action is crucial; it utilizes the flat base plane of the front surface of the door frame 4, allowing mounting base 3 to achieve precise self-alignment in both the horizontal and vertical directions, eliminating the need for complex manual measurements and calibrations, fundamentally ensuring the correct installation position of the subsequent guide rails. After precise positioning, mounting base 3 is securely connected and anchored to the door frame 4 using fixing screws through the pre-set positioning mounting holes 31 on mounting base 3. At this point, a precisely positioned and stable mounting base is complete.

[0042] 2. Quick-connection of the guide rail body: After the mounting base 3 is fixed, the installation of the guide rail body 1 becomes extremely simple. The operator only needs to bring the guide rail body 1 close to the mounting base 3, aligning the recessed snap-fit ​​groove 2 at its upper end with the snap-fit ​​device extending downward from the bottom of the mounting base 3. The snap-fit ​​device of this utility model preferably consists of a first elastic arm 7 and a second elastic arm 8 arranged symmetrically. These elastic arms have guide protrusions 9 facing the groove wall of the snap-fit ​​groove 2, and the upper and lower sides of these guide protrusions 9 are also provided with inclined guide surfaces 91.

[0043] When the guide rail body 1 is pushed downwards, the inner wall of the latching groove 2 first contacts the inclined guide surface 91 on the elastic arm. The inclined guide surface 91 can effectively convert the vertical thrust into a horizontal component force, guiding the elastic arm to smoothly deform and contract inwards. As the guide rail body 1 continues to descend, the elastic arm and its guide protrusion 9 will eventually pass through the narrow opening of the latching groove 2 and instantly open outwards with its own elastic force, allowing the guide protrusion 9 to accurately engage in the locking position within the latching groove 2, thereby achieving a quick, accurate, and secure engagement between the guide rail body 1 and the mounting base 3. In addition, the anti-detachment protrusion 5 extending inwards from the opening of the latching groove 2 forms an additional protective line after engagement, effectively preventing the guide rail body from accidentally disengaging due to unexpected vibration or external force, greatly enhancing the reliability and safety of the system.

[0044] 3. Auxiliary Fixing: After the core snap-fit ​​fixing is completed, several auxiliary mounting holes 10 on the guide rail body 1 can be used for secondary fixing as needed, further enhancing the firmness and stability of the guide rail body. Finally, after the guide rail body 1 is connected to the mounting base 3, the decorative plate 11 extending upward from the front end of the guide rail body 1 will cleverly cover the front of the front baffle 6, not only hiding the functional components but also giving the entire installation structure a simple and integrated aesthetic effect, enhancing the overall grade of the product.

[0045] Through the ingenious design and collaborative work described above, this utility model not only completely solves the core problem of extremely high parallelism requirements and easy jamming in the installation of existing PD door hanging rails, but also realizes the fast, accurate, stable and aesthetically pleasing installation of the guide rail system, greatly enhancing the product's market competitiveness and user experience.
