Description

Technical Field

[0001] This utility model belongs to the technical field of aluminum alloy door and window accessories, specifically relating to an easy-to-install aluminum alloy door and window sliding rail. Background Technology

[0002] With the improvement of living standards, aluminum alloy doors and windows are widely used in the construction field due to their advantages such as light weight, high strength, durability and small deformation.

[0003] Traditional aluminum alloy door and window installations require fixing the door and window frame to the wall before installing the door and window into the frame's sliding rails. However, existing aluminum alloy door and window sliding rails have many problems: for example, the vertical installation space for doors and windows is small, requiring the doors and windows to be crammed into the rails during installation, which is cumbersome and inconvenient, and can easily lead to uneven stress and glass breakage; at the same time, the rails are usually fixed inside the base with bolts or welding, making disassembly and replacement inconvenient. These problems cause great trouble for the installation and subsequent maintenance of aluminum alloy doors and windows. Therefore, designing an easy-to-install aluminum alloy door and window sliding rail is of great practical significance.

[0004] To address the aforementioned issues, this application proposes an easy-to-install aluminum alloy door and window sliding track. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figures 1-5 The present invention provides the following technical solution: an easy-to-install aluminum alloy door and window sliding rail, including a sliding rail body 2 and a connecting component for connecting the sliding rail body 2 and the door and window frame beam 1. The connecting component includes a positioning mechanism 3 and an operable locking mechanism.

[0035] Optionally, by Figure 1 and Figure 2 As shown, in this embodiment, the positioning mechanism 3 is used to align the slide rail body 2 with the door and window frame beam 1; the operable locking mechanism has an operating end exposed on the door and window frame beam 1, which can selectively fix or separate the door and window frame beam 1 from the slide rail body 2 by operating the operating end. The positioning mechanism 3 includes a protrusion and a recess adapted to the protrusion. The protrusion and recess are respectively disposed on one of the slide rail body 2 and the other of the door and window frame beam 1, and the extending direction of the protrusion is consistent with the installation direction of the door and window frame beam 1. The protrusion includes at least two positioning posts 31 fixed inside the door and window frame beam 1, and the recess includes a positioning hole 21 opened on the slide rail body 2. The diameter of the positioning post 31 is adapted to the inner diameter of the positioning hole 21. The positioning mechanism 3 also includes a telescopic spring 32, which is sleeved on... With the positioning post 31 positioned between the inner bottom surface of the door and window frame beam 1 and the slide rail body 2, the above-mentioned solution allows for precise alignment during the installation of the aluminum alloy door and window slide rail. Since the protrusion extends in the same direction as the installation of the door and window frame beam 1, the operator simply aligns the positioning hole 21 on the slide rail body 2 with the positioning post 31 inside the door and window frame beam 1 and pushes the slide rail body 2 in the installation direction. The positioning post 31 then slides smoothly into the positioning hole 21. At this time, the telescopic spring 32 sleeved on the positioning post 31 is compressed, and its elastic force provides upward support to the slide rail body 2, temporarily lifting it up. This prevents positioning deviation due to the slide rail body 2's own weight during subsequent operations, providing a stable foundation for the fixed operation of the operable locking mechanism.

[0036] After alignment is completed, the operator operates the operable locking mechanism through the operating end exposed on the door and window frame beam 1. When the operating end is triggered to the locked state, the operable locking mechanism will generate a corresponding locking force, which will firmly fix the slide rail body 2 on the door and window frame beam 1. At this time, the telescopic spring 32 still maintains a certain amount of compression. Its elastic force and the locking force of the operable locking mechanism work together to further enhance the stability of the connection between the two and prevent the slide rail body 2 from loosening or shaking during use.

[0037] When it is necessary to disassemble or maintain the slide rail body 2, simply reverse the operation of the operable locking mechanism to release the fixation of the slide rail body 2 and the door and window frame beam 1. At this time, the telescopic spring 32 extends under its own elastic restoring force, pushing the slide rail body 2 upward, so that the positioning post 31 gradually comes out of the positioning hole 21. The operator can easily pull out the slide rail body 2 in the installation direction to complete the separation operation. The whole process relies on the guidance of the positioning mechanism 3 and the convenient operation of the operable locking mechanism to realize the rapid installation and disassembly of aluminum alloy door and window slide rails.

[0038] Optionally, by Figure 1 , Figures 3-5As shown, in this embodiment, the operable locking mechanism includes a locking mechanism 4 and a driving mechanism 5. The locking mechanism 4 can move along a preset trajectory to insert into or disengage from the locking engagement part of the slide rail body 2. The driving mechanism 5 is connected to the locking mechanism 4 in a transmission manner, and one end of the driving mechanism 5 extends out of the door and window frame beam 1 and forms the operating end of the operable locking mechanism. A locking strip 22 is fixed on the bottom surface of the slide rail body 2, and a locking hole 222 is provided on the locking strip 22. The locking mechanism 4 includes two symmetrically distributed and movably disposed in the door and window frame beam 1 movable plates 41 and a locking block 42 fixed on the movable plates 41. The driving mechanism 5 drives the two movable plates 41 to move closer or further away from each other so that the locking block 42 inserts into or disengages from the locking hole 222. The driving mechanism 5 includes a bidirectional threaded screw 51 rotatably disposed in the door and window frame beam 1 and an internal hexagonal knob 52. The two movable plates 41 are respectively engaged with the two reverse threads of the bidirectional threaded screw 51. One end of the bidirectional threaded screw 51 extends out of the door and window frame beam 1, and the internal hexagonal knob 52 is fixed to the bidirectional threaded screw 51. The protruding end of rod 51 forms the operating end of an operable locking mechanism. A stepped hole 11 for inserting an internal hexagonal knob 52 is provided on the outer wall of the door and window frame beam 1. With the above solution, when it is necessary to fix the slide rail body 2 to the door and window frame beam 1, the operator uses an internal hexagonal wrench to insert the internal hexagonal knob 52 and rotates the internal hexagonal knob 52 clockwise, which will drive the bidirectional threaded screw 51 to rotate synchronously. Since the two moving plates 41 are respectively engaged with the two reverse threads of the bidirectional threaded screw 51, the bidirectional threaded screw... When the lever 51 rotates, the two moving plates 41 will move closer to each other along the preset trajectory. As the moving plates 41 move, the locking block 42 fixed on them gradually extends into the locking hole 222 on the locking strip 22 on the bottom surface of the slide rail body 2 until the locking block 42 is fully embedded in the locking hole 222. At this time, stop rotating the hexagonal knob 52, and the slide rail body 2 will be firmly fixed on the door and window frame beam 1. The hexagonal knob 52 is embedded in the step hole 11 on the outer wall of the door and window frame beam 1, which can avoid the problem of bumping caused by the protruding hexagonal knob 52.

[0039] When it is necessary to disassemble or adjust the slide rail body 2, the operator uses an Allen wrench to turn the Allen knob 52 in the opposite direction. The double-threaded screw 51 then rotates in the opposite direction, causing the two moving plates 41 to move away from each other. The locking block 42 gradually exits from the locking hole 222 along with the moving plates 41. When the locking block 42 is completely disengaged from the locking hole 222, the locking state is released. At this time, under the elastic force of the telescopic spring 32, the slide rail body 2 is lifted upward. The operator can easily pull out the slide rail body 2 along the direction of the positioning post 31 to separate the slide rail body 2 from the door and window frame beam 1.

[0040] The entire locking and unlocking process can be completed by simply operating the internal hex knob 52. With the guiding function of the positioning mechanism 3, it not only ensures the stability of the connection, but also greatly improves the convenience of installation and disassembly.

[0041] It should be noted that during subsequent installation of doors and windows, the sliding rail body 2 needs to be temporarily unlocked. At this time, the sliding rail body 2 can move up and down within the door and window frame beam 1, providing a larger installation space for the doors and windows. When installing the doors and windows, align the doors and windows with the sliding rail body 2. Relying on the weight of the doors and windows and the push of the installer, the doors and windows push the sliding rail body 2 down (the operation of the upper sliding rail body 2 is the same), providing a larger installation space for the doors and windows, reducing the need for forced insertion, and reducing the risk of glass breakage. After the doors and windows are pushed into the installation position, the upper and lower sliding rail bodies 2 use the elasticity of the telescopic spring 32 to clamp the doors and windows, achieving pre-installation. At this time, the locking block 42 corresponds to the locking hole 222 (or the two are aligned after manually fine-tuning the height of the sliding rail body 2). Then, the locking mechanism 4 locks the sliding rail body 2 by operating the drive mechanism 5. The process of disassembling the doors and windows is the reverse of the above process.

[0042] Preferably, by Figure 1 , Figures 3-5 As shown in this embodiment, the drive mechanism 5 further includes two guide rods 53. The two guide rods 53 are symmetrically fixed inside the door and window frame beam 1 and pass through the moving plate 41. With the above solution, during use, when the moving plate 41 moves along the bidirectional threaded screw 51, its through hole maintains a sliding fit with the guide rod 53. The guide rod 53 strictly limits the movement trajectory of the moving plate 41, avoiding the moving plate 41 from tilting or rotating due to the rotational force of the bidirectional threaded screw 51.

[0043] Preferably, by Figure 1 , Figure 3 and Figure 4 As shown in this embodiment, the end of the locking block 42 away from the moving plate 41 is machined with a chamfer 421, and the bottom surface of the locking strip 22 is provided with a clearance opening 221. When the locking block 42 is inserted into the locking hole 222, the bidirectional threaded screw 51 and the guide rod 53 pass through the clearance opening 221. With the above solution, if there is a slight alignment deviation between the locking block 42 and the locking hole 222 during use, the chamfer 421 will first contact the edge of the locking strip 22, and automatically correct the position through the guiding effect of the chamfer, so that the locking block 42 can smoothly slide into the locking hole 222, avoiding jamming or jamming caused by assembly errors, and greatly improving the fault tolerance of the locking operation.

[0044] When the locking block 42 is fully inserted into the locking hole 222, the bidirectional threaded screw 51 and the guide rod 53 pass through the clearance opening 221 on the bottom surface of the locking bar 22. This structural design cleverly avoids the spatial interference of the locking bar 22 on the bidirectional threaded screw 51 and the guide rod 53, so that the locking bar 22 can fit tightly with the slide rail body 2. This ensures the effective matching length between the locking block 42 and the locking hole 222, and also ensures the smooth operation of each component of the drive mechanism 5, avoiding motion obstruction caused by structural interference.

[0045] Components not described in detail in this article are existing technologies.

[0046] The working principle and usage process of this utility model: When using and installing the aluminum alloy door and window sliding rail of this utility model, the operator first aligns the sliding rail body 2 with the installation position of the door and window frame beam 1. Since the extension direction of the positioning column 31 in the positioning mechanism 3 is consistent with the installation direction, the positioning hole 21 on the sliding rail body 2 is aligned with the positioning column 31 along the installation direction and pushed in. The positioning column 31 can then slide smoothly into the positioning hole 21 and complete the initial alignment. At this time, the telescopic spring 32 sleeved on the positioning column 31 is compressed by the sliding rail body 2, generating an upward elastic support force, which temporarily lifts the sliding rail body 2 to prevent it from shifting due to its own weight, providing a stable foundation for subsequent locking operations. At the same time, the locking strip 22 on the bottom surface of the sliding rail body 2 is in place synchronously with the sliding rail, and the clearance 221 on its bottom surface corresponds exactly to the position of the bidirectional threaded rod 51 and guide rod 53 in the door and window frame beam 1, reserving movement space for the drive mechanism 5.

[0047] After positioning is completed, the operator uses an Allen wrench to insert the Allen knob 52 embedded in the stepped hole 11 and rotates the knob clockwise to drive the double-threaded screw 51 to rotate. Since the two moving plates 41 are respectively engaged with the two reverse threads of the double-threaded screw 51, and the moving plates 41 are restricted to linear movement by the through guide rod 53, when the double-threaded screw 51 rotates, the two moving plates 41 move closer to each other smoothly and parallelly along the guide rod 53.

[0048] During the movement, the locking block 42 fixed on the moving plate 41 moves closer to the locking hole 222 of the locking strip 22. If there is a slight assembly deviation, the chamfer 421 at the end of the locking block 42 will first contact the edge of the locking strip 22. The position will be automatically corrected by the inclined guide, so that the locking block 42 can slide precisely into the locking hole 222. When the locking block 42 is fully embedded in the locking hole 222, the rotation of the internal hexagonal knob 52 will stop. At this time, the bidirectional threaded screw 51 and the guide rod 53 pass through the clearance 221 of the locking strip 22 to avoid structural interference. Finally, the cooperation between the locking block 42 and the locking hole 222 and the elastic support of the telescopic spring 32 work together to firmly fix the slide rail body 2 on the door and window frame beam 1, ensuring that there is no loosening during use.

[0049] When it is necessary to disassemble or adjust the slide rail, the operator uses an Allen wrench to turn the Allen knob 52 in the opposite direction. The double-threaded screw 51 rotates in the opposite direction, causing the two moving plates 41 to move away from each other under the constraint of the guide rod 53. The locking block 42 gradually exits from the locking hole 222 along with the moving plate 41. The chamfer 421 reduces the frictional resistance during the exit process, ensuring a smooth disengagement process.

[0050] When the locking block 42 is completely disengaged from the locking hole 222, the elastic force of the telescopic spring 32 is released, pushing the slide rail body 2 upward, so that the positioning pin 31 gradually comes out of the positioning hole 21. The operator only needs to gently pull the slide rail body 2 in the opposite direction of installation to completely separate it from the door and window frame beam 1.

[0051] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
