Description

Technical Field

[0001] This utility model relates to the field of sliding door technology, and more specifically, to aluminum alloy sliding doors. Background Technology

[0002] Aluminum alloy sliding doors are sliding doors made of aluminum alloy extruded profiles as frames, mullions, and sashes. They are lightweight, high-strength, have good sealing performance, beautiful appearance, and strong corrosion resistance, and are widely used for space partitioning in kitchens, balconies, and other areas.

[0003] In modern home decoration, trackless designs can better integrate into various decorating styles, enhancing the aesthetics of the home. Traditional tracked sliding doors are prone to dust and dirt accumulation on the bottom track, making cleaning relatively difficult. Trackless designs avoid this problem; a simple wipe is all it takes to keep the door clean, greatly saving time and effort. Therefore, many families choose trackless sliding doors as partitions in their homes. However, because trackless sliding doors only have one support point at the top, they can tilt during sliding due to the pulling force, increasing wear on the top track and reducing the door's lifespan. Therefore, a new solution is needed to address this issue. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an aluminum alloy sliding door. By setting pulley assemblies and limiting assemblies on both sides of the door body, the movement path of the door body is more fixed, reducing the probability of the door body tilting due to tension.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: The aluminum alloy sliding door includes a door frame and two tracks fixedly connected inside the door frame. Door body one and door body two are slidably connected to the two tracks respectively. Door body one and door body two have the same structure and are symmetrically arranged along the junction of the two tracks. A storage groove for storing the tracks is opened inside the door frame. Limiting rails are fixedly connected to the inner walls of the storage groove on both sides along the width direction. Several pulley assemblies are fixedly connected to the side of door body one away from door body two. The side of the pulley assembly away from door body one is slidably connected to the limiting rail. Limiting assemblies are fixedly connected to both sides of door body one in the width direction. The ends of the two sets of limiting assemblies away from door body one are fixedly connected to the side walls at both ends of the length direction of the storage groove respectively. When the limiting assemblies are fully extended, the two sides of the limiting assemblies in the width direction abut against the limiting rail and door body two respectively.

[0006] The present invention is further configured such that: the pulley assembly includes a C-shaped fixing member and a roller, the fixing member is fixedly connected to the door body, the roller is rotatably connected to the inner wall of the fixing member, and the side of the roller away from the door body abuts against the inner wall of the limiting rail and rolls within the limiting rail.

[0007] The present invention is further configured such that: the limiting component includes several limiting blocks with an I-shaped cross-section, adjacent limiting blocks are fixedly connected by a telescopic rod, the limiting block closer to the door body is fixedly connected to the door body by a connecting rod, and the limiting block farther from the door body is fixedly connected to the inner side wall of the storage groove by a telescopic rod.

[0008] The present invention is further configured such that: one side of the limiting block along the width direction of the door frame abuts against the second door body, and the other side of the limiting block abuts against the outer wall of the limiting rail located away from the second door body.

[0009] The present invention is further configured such that: the maximum length of the first telescopic rod is one-third of the maximum travel distance of the first door body, and the maximum length that the second telescopic rod can be stretched is the minimum distance between the first door body and the inner wall of one end of the door frame.

[0010] The present invention is further configured such that: a protective strip is fixedly connected to the side of the door body one near the door body two, and the side of the protective strip away from the door body one abuts against the limiting blocks arranged on both sides of the door body two.

[0011] In summary, this utility model has the following beneficial effects: The aluminum alloy sliding door has rollers on both sides of the door body (door one and door two) that are far apart from each other. The rollers, in conjunction with the limiting rail, reduce the impact on the door body (door one and door two). The probability of door body two tilting away from each other when subjected to pulling force is reduced. Both sides of door body one and door body two are equipped with limit blocks. When one side of door body one or door body two separates from the inner wall at both ends of the storage groove, the limit block will move with door body one or door body two, thereby reducing the probability of door body one and door body two tilting towards each other when subjected to pulling force. The limit blocks, limit rails and rollers work together to reduce the probability of door body one and door body two tilting to the sides during the pushing and pulling process, reducing the probability of wear on the upper track and hanging rollers due to tilting, and extending the service life of the sliding door.

[0014] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0015] This aluminum alloy sliding door, such as Figures 1-5 As shown, the device includes a door frame 1. A storage groove 5 is formed on the lower surface of the door frame 1. Two tracks 2 are welded to the inner top surface of the storage groove 5. Door body 3 and door body 4 are slidably connected to the two tracks 2 via rollers. Door body 3 and door body 4 have identical structures and are symmetrically arranged along the junction of the two tracks 2. Limiting rails 6 are welded to the inner walls of the storage groove 5 on both sides along its width. A pulley assembly 7 is riveted to the side of door body 3 away from door body 4. The pulley assembly 7 abuts against the inner wall of the limiting rail 6 on the side away from door body 3 and slides on the inner wall of the limiting rail 6. The limiting rails 6 and pulley assembly 7 on door body 3 and door body 4 reduce the probability of door body 3 and door body 4 tilting in opposite directions due to the operator's pulling force while moving along the tracks 2, as they are supported only by the top. Limiting components 8 are fixedly connected to both sides of the width direction of door body 3. The ends of the two sets of limiting components 8 away from door body 3 are fixedly connected to the side walls at both ends of the length direction of the storage groove 5. When the limiting components 8 are fully extended, the two sides of the limiting components 8 in the width direction abut against the limiting rail 6 and door body 4 respectively. The limiting components 8 set on door body 3 and door body 4 can reduce the probability of door body 3 and door body 4 tilting towards each other under the action of the operator's pulling force, since door body 3 and door body 4 are only supported by the upper rail 2 during the movement. The pulley assembly 7, the limiting rail 6 and the limiting components 8 cooperate with each other to reduce the probability of door body 3 and door body 4 swaying and tilting along the width direction of door frame 1 during the sliding process, thereby reducing the wear of the hanging rollers caused by the shaking of the door body and increasing the service life of the sliding door.

[0016] like Figure 2 and Figure 3As shown, the pulley assembly 7 includes a C-shaped fixing member 701 and a roller 702. The fixing member 701 is riveted to the door body 3, and the roller 702 is rotatably connected to the inner wall of the fixing member 701. The diameter of the roller 702 is larger than the width of the fixing member 701, so a portion of the roller 702 away from the door body 3 can pass through the fixing member 701 and abut against the inner wall of the limiting rail 6. When the door body 3 and the door body 4 move, the rollers provided on the side walls of the door body 3 and the door body 4... Roller 702 will roll on the two limiting rails 6 respectively. The setting of roller 702 reduces the friction between door 3 and door 4 and the limiting rail 6 when the limiting rail 6 restricts the tilting of door 3 and door 4, and reduces the resistance when moving door 3 and door 4. At the same time, roller 702 abuts against the inner wall of the corresponding limiting rail 6, which can reduce the probability that the side of door 3 and door 4 closest to the ground will tilt away from each other during the movement.

[0017] like Figures 2-5 As shown, the limiting component 8 includes three limiting blocks 801 with an I-shaped cross-section. A telescopic rod 802 is provided between adjacent limiting blocks 801. The two ends of the telescopic rod 802 are welded to two limiting blocks 801 respectively. The limiting block 801 furthest from the door body 3 is connected to the inner wall of the door frame 1 via a telescopic rod 804. The two ends of the telescopic rod 804 are welded to the inner wall of the door frame 1 and the adjacent limiting block 801 respectively. Both the telescopic rod 802 and the telescopic rod 804 are multi-segment telescopic rods, so that when the door body 3 or the door body 4 is located at one end of the length direction of the door frame 1, the three limiting blocks 801 closest to the door frame 1 can be housed in the space between the track 2 and the inner wall of the door frame 1. The limiting block 801 near door body 3 is connected to door body 3 via a connecting rod 803. One end of the connecting rod 803 is welded to the limiting block 801 and the other end is riveted to door body 3. The length of the connecting rod 803 is fixed. When door body 3 moves, the limiting block 801 can be driven to move synchronously through the connecting rod 803. One side of the limiting block 801 along its length abuts against door body 4 and the other side abuts against the outer wall of the limiting rail 6 set away from door body 4. If door body 4 needs to move at this time, since door body 4 abuts against the outer wall of the limiting rail 6 set away from door body 4 through the limiting block 801, the probability of door body 4 tilting towards door body 3 can be reduced.

[0018] like Figure 4 and Figure 5As shown, the maximum length of the telescopic rod 802 is one-third of the maximum travel distance of the door 3. When the door 3 moves to one-third of its maximum travel distance, the telescopic rod 802 is stretched to its maximum value, so the limiting block 801 near the door 3 can be driven by the telescopic rod 802 to move towards the door 3. When the door 3 moves to two-thirds of its maximum travel distance, the limiting block 801 in the middle can be driven by the telescopic rod 802 to move towards the door 3. Since the maximum length that the telescopic rod 804 can stretch is the minimum distance between the door 3 and the inner walls of both ends of the door frame 1, the three limiting blocks 801 can be evenly arranged along the width direction of the door 4, so that the door 4 can be relatively evenly restricted by the limiting blocks 801 during the movement.

[0019] like Figure 4 and Figure 5 As shown, a protective strip 9 is attached to the side of door body 3 near door body 4. Since door body 3 and door body 4 often have borders for protection and aesthetic enhancement along their width and bottom edges, the protective strip 9 can compensate for the problem that door body 3 or door body 4 cannot abut against the limiting block 801 because the thickness of the border is often greater than the thickness of door body 3 or door body 4. On the other hand, the protective strip 9 can prevent door body 3 and door body 4 from making direct contact with the limiting block 801, thereby reducing the probability of wear and tear caused by friction between door body 3 and door body 4 and the limiting block 801 during movement.

[0020] Working principle: This aluminum alloy sliding door has a recessed storage groove 5 on the lower surface of the door frame 1. Door body 3 and door body 4 are slidably connected to the inner top surface of the storage groove 5 via a track 2. Limiting rails 6 are provided on the inner walls of both sides of the storage groove 5 on the opposite sides of door body 3 and door body 4. Rollers 702 are rotatably connected to the opposite sides of door body 3 and door body 4 via fixing parts 701. The rollers 702 abut against the inner wall of the limiting rails 6 and roll on the inner wall of the limiting rails 6. Three limiting blocks 801 are connected to both sides of door body 3 and door body 4 in the width direction via connecting rods 803. Adjacent limiting blocks 801 are connected by telescopic rods 802 and are far from the limiting blocks of door body 3 or door body 4. Block 801 is connected to the inner walls of both ends of the storage groove 5 via telescopic rod 804. When one side of door 3 or door 4 is in contact with the wall along the width direction, the three limiting blocks 801 are stored in the space between door 3 or door 4 and the inner wall of one end of the door frame 1. When door 3 or door 4 is pulled and separated from the wall, the three limiting blocks 801 are moved by connecting rod 803 and telescopic rod 802. At this time, door 3 or door 4 abuts against the limiting block 801 set on one side of door 4 or door 3 via protective strip 9. The limiting block 801, roller 702 and limiting rail 6 cooperate with each other to reduce the probability of door 3 and door 4 tilting during the process of being pulled.
