Description

Technical Field

[0001] This utility model particularly relates to a sliding rail assembly that can adapt to different door types. Background Technology

[0002] The door structure includes a door body, an upper door frame, and a lower door frame. A roller assembly is installed at the upper end of the door body, and an upper slide rail and a lower slide rail are respectively installed within the upper and lower door frames. The roller assembly of the door body slides in conjunction with the upper slide rail, and the lower end of the door body slides in conjunction with the lower slide rail to achieve the opening and closing of the door. Existing lower slide rails include a base with a groove on the base that fits the door body. The door body can move within the groove, but the size of the groove is preset, meaning the groove can only be used with specific door bodies, which greatly limits its application. Utility Model Content

[0025] A sliding rail assembly adaptable to different door types, see reference. Figures 1-5 It includes a base plate 1, on which slide grooves 2 are symmetrically arranged, and a fixed seat 3 is arranged between the two slide grooves 2. A positioning member is movably arranged on the fixed seat 3. Openings 4 communicating with the slide grooves 2 are respectively opened on both sides of the fixed seat 3. The positioning member moves relative to the fixed seat 3 so that the positioning member extends into the slide groove 2 to limit different door bodies 5.

[0026] Furthermore, the positioning element includes a bolt and a linkage block 62 connected to the screw 61. The screw head 63 is limited on the fixed seat 3. The linkage block 62 can move relative to the screw 61 to adjust the position of the linkage block 62 extending into the slide groove 2.

[0027] Furthermore, the linkage block 62 is provided with an adjustment part 621 that cooperates with the door body 5.

[0028] Furthermore, the opening 4 is provided with a first inclined surface 11, and the adjusting part 621 is provided with a second inclined surface 110 that slides in cooperation with the first inclined surface 11.

[0029] Furthermore, the fixed base 3 is provided with a limiting groove 631 for limiting the screw head 63.

[0030] Furthermore, there are two bolts respectively located at both ends of the fixed base 3. Each bolt is connected to a linkage block 62, and each linkage block 62 is provided with two adjustment parts 621. The fixed base 3 has openings 4 corresponding to the number of adjustment parts 621.

[0031] Furthermore, a mounting shell 7 is detachably installed on the fixing base 3, and the mounting shell 7 is used to confine the bolt within the fixing base 3.

[0032] The working principle of this utility model is as follows:

[0033] The position of the positioning component that needs to extend into the slide groove 2 is determined according to the size of the door body 5. Taking the bolt and linkage block 62 structure as an example in Embodiment 1, after the positioning component is assembled on the fixed seat 3, the adjustment part 621 on the linkage block 62 extends into the slide groove 2 through the opening 4. That is, the adjustment part 621 and the slide groove 2 together form a channel for the door body 5 to slide. In other words, this application mainly adjusts the position of the adjustment part 621 in the slide groove 2. The adjustment part 621 is moved by the linkage block 62, that is, the length of the adjustment part 621 extending through the opening 4 is adjusted, thereby adjusting the position of the adjustment part 621 in the slide groove 2, thereby adjusting the size of the channel formed by the slide groove 2 and the adjustment part 621, so as to adapt to the sliding fit of door bodies 5 with different widths.

[0034] The specific installation method is as follows: First, remove the bolt and linkage block 62. The bolt and linkage block 62 are threadedly connected. After adjusting the position of linkage block 62 on screw rod 61 outside the fixed seat 3, put linkage block 62 and bolt into the fixed seat 3, so that screw head 63 is limited in the limiting groove. At this time, screw head 63 cannot move. At this time, the adjusting part 621 on linkage block 62 extends into slide groove 2 through opening 4. Since linkage block 62 is fixed on screw rod 61, the relative position of adjusting part 621 and slide groove 2 remains unchanged. When the lower end of door body 5 is located in slide groove 2, adjusting part 621 and slide groove 2 together form a channel for sliding cooperation of door body 5. Since the position of adjusting part 621 in slide groove 2 can be adjusted, it can be matched with door body 5 of different sizes for installation, and its application scenarios are more extensive.

[0035] As a preferred embodiment, two openings 4 are preferably made on both sides of the fixing base 3, and bolts are respectively provided at both ends inside the fixing base 3, with a linkage block 62 connected to each bolt, such as... Figure 1 As shown, when the lower end of the door 5 reciprocates in the slide groove 2, the two adjustment parts 621 and the slide groove 2 together form a channel for the lower end of the door 5 to move.

[0036] Based on the above technical solution, since the door 5 moves in the horizontal direction, it exerts a horizontal force on the linkage block 62, so the linkage block 62 will not disengage from the fixed seat 3. However, in order to further improve the stability of the linkage block 62, this application has a detachable mounting shell 7 on the fixed seat 3. The mounting shell 7 can be fixed on the fixed seat 3 by plugging in. When the mounting shell 7 is installed on the fixed seat 3, the mounting shell 7 further limits the bolts inside the fixed seat 3.

[0037] Based on the above technical solution, this application provides a first inclined surface 11 at the opening 4 and a second inclined surface 110 that slides with the first inclined surface 11 on the adjustment part 621. When the linkage block 62 drives the adjustment part 621 to move, the second inclined surface 110 on the adjustment part 621 moves along the first inclined surface 11. The setting of the first inclined surface 11 has a guiding effect on the movement trajectory of the adjustment part 621.

[0038] In order to accommodate the installation and application of more door bodies 5, this application adjusts the position of the positioning member passing through the opening 4 and thus adjusts the length of the positioning member extending into the slide groove 2. This adjusts the size of the channel formed by the positioning member and the slide groove 2 for sliding fit of the door body 5, so that sliding fit of various door bodies 5 with different widths can be applied.

[0039] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
