Description

Technical Field

[0001] This utility model relates to the field of sliding door technology, and in particular to an installation structure for a sliding door. Background Technology

[0002] Sliding doors are a common type of door in homes, typically used in wardrobes, bookcases, closets, and bedrooms. A sliding door consists of a door frame and door panels that slide along the frame. The door panels are usually connected to the lower frame via tracks and rollers, facilitating sliding. The door panels slide onto the upper frame, and the panels slide in tandem. During manufacturing, controlling the size and width of the door panel and frame is challenging. If the width is too large, it will wobble and produce noise when installed on the upper frame; if the width is too small, it may not fit during installation or will affect the sliding mechanism. Furthermore, manufacturing errors are easily introduced, and the width cannot be adjusted after manufacturing, affecting installation accuracy and making it difficult to achieve the correct standard dimensions. Utility Model Content

[0003] To address the problems of the prior art, this utility model provides an installation structure for a sliding door that allows adjustment of the width of the door panel slider to a standard width, thereby improving installation accuracy.

[0004] The technical solution adopted is as follows:

[0005] An installation structure for a sliding door includes an upper door frame and a leaf frame. The leaf frame is slidably mounted on the upper door frame. The upper door frame is provided with a slide rail for the leaf frame to slide on. The leaf frame is provided with a slider that is interference-fitted with the slide rail. The slider has an adjustment structure in the middle that can adjust the width of the slider.

[0006] Furthermore, a sealing strip is provided between the slider and the slide rail.

[0007] Furthermore, there are two sealing strips, which are respectively snapped onto the side plates on both sides of the slider.

[0008] Furthermore, the adjustment structure includes a mounting block fixedly installed on the fan frame, an adjustment block adjustable on the mounting block for adjusting the width of the slider, and a fixing bolt for fixing the adjustment block to the mounting block.

[0009] Furthermore, the mounting block is provided with a sliding groove for the adjustment block to slide.

[0010] Furthermore, a spring is provided between the slide and the adjusting block.

[0011] Furthermore, two fixing bolts are provided, located on the adjusting block and the mounting block.

[0012] Furthermore, the mounting block is provided with a first drive plate that cooperates with one side plate of the fan frame, and the adjusting block is provided with a second drive plate that cooperates with the other side plate of the fan frame.

[0013] Furthermore, both the first drive plate and the second drive plate are provided with drive blocks that cooperate with the corresponding side plates.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This utility model provides an installation structure for a sliding door. The door frame can slide onto the upper door frame. A slider on the door frame and a slide rail on the upper door frame are interference-fitted. An adjustment mechanism within the slider allows for adjustment of its width, ultimately bringing it to a standard size. This improves installation accuracy, preventing wobbling due to an excessively wide slider and ensuring smooth sliding without hindering operation due to an excessively narrow slider. The adjustment mechanism allows for easy installation and disassembly. Furthermore, the adjustable structure allows for greater tolerance during door frame manufacturing; any errors in the slider width during manufacturing can be reduced or eliminated by adjusting the structure.

Detailed Implementation

[0022] The present invention will be further described below with reference to specific embodiments.

[0023] refer to Figure 1-6An installation structure for a sliding door includes an upper door frame 1 and a leaf frame 2. The leaf frame 2 is slidably mounted on the upper door frame 1. The upper door frame 1 is provided with a slide rail 3 for sliding the leaf frame. The leaf frame 2 is provided with a slider 4 that is interference-fitted with the slide rail. An adjustment structure 5 is provided in the middle of the slider 4 to adjust its width. The adjustment structure 5 is mounted on the profile of the leaf frame 2 by screws.

[0024] A sealing strip 8 is provided between the slider 4 and the slide rail. Two sealing strips 8 are provided, each snapped onto the side plates 9 on both sides of the slider 4. The sealing strips are used for sealing and have functions such as sealing, dust prevention, and noise reduction.

[0025] The slider 4 is made smaller than the standard size, allowing for an interference fit between the slider 4 and the slide rail before adjustment, providing adjustable space for the slider 4. The adjustment structure 5 is located in the middle of the slider 4. Before installation, the width of the slider 4 needs to be increased, i.e., the distance between the two side plates 9, to ensure the slider is wide enough to be installed on the slide rail 3. Then, as needed, the adjustment structure 5 is adjusted to bring the width of the slider 4 to the standard size for fitting with the slide rail 3. This improves installation accuracy. Even if the slider 4 has some machining errors, it can be adjusted using the adjustment structure 5, resulting in a larger tolerance. The slider width will not wobble due to being too large, nor will it be too small to install or affect push-pull operation. The adjustment structure 5 can adjust the width of the slider 4 as needed, facilitating installation and disassembly.

[0026] The adjustment structure 5 includes a mounting block 501 fixedly mounted on the fan frame 2, an adjustment block 502 adjustable for the width of the slider 4 mounted on the mounting block, and a fixing bolt 503 for fixing the adjustment block 502 to the mounting block. The mounting block 501 has a first drive plate 10 that engages with one side plate of the fan frame 2, and the adjustment block 502 has a second drive plate 11 that engages with the other side plate of the fan frame 2. Preferably, both the first and second drive plates have drive blocks 12 that engage with the corresponding side plates 9. By providing drive blocks 12, the contact area between the drive blocks 12 and the side plates 9 is smaller. Compared to directly driving the side plates 9 with the first and second drive plates, the drive blocks 12 can provide a greater driving force and a more significant driving effect.

[0027] The adjusting block 502 is slidably mounted on the mounting block 501. By driving the adjusting block 502 to slide, the distance between the mounting block 501 and the adjusting block 502 is changed. By cooperating with the first driving plate and the second driving plate and the corresponding side plate, the distance between the two side plates of the slider can be increased.

[0028] The mounting block 501 is provided with a sliding groove 6 for the adjusting block 502 to slide. The mounting block 501 includes three extension blocks 13 disposed within the sliding groove 6. The extension blocks 13 can slide on the sliding groove 6. Before installation, marks can be made on the mounting block 501 according to the standard width. After the adjusting structure 5 is installed on the slider, it can be adjusted to the corresponding position, i.e., the standard size, according to the marks. Preferably, two fixing bolts 503 are provided, located on the adjusting block 502 and the mounting block 501. The fixing bolts 503 can be located on the extension blocks 13 on both sides for better fixation.

[0029] A spring 7 is provided between the sliding groove and the adjusting block 502. The spring 7 maintains a certain distance between the adjusting block and the mounting block 501, which helps to fix the position of the adjusting block. The above description is only an optional embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the content of this specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
