Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same numbers.

Referring to Figures 1 and 2, a first embodiment of the slide rail adjusting device of the present invention is suitable for installation on a cabinet. The cabinet includes a cabinet (not shown) and a drawer that can be opened and closed relative to the cabinet. (Not shown in the figure), and a sliding rail mechanism 1. The drawer has a door panel on the front side, and the gap between the door panel and the cabinet body is a door gap. The slide rail mechanism 1 is commonly known as a horse-riding draw rail, and includes a fixed rail unit 11 fixedly arranged in the cabinet, and a movable rail unit 12 fixedly combined with the drawer. The rail unit 12 and the drawer can slide back and forth along the fixed rail unit 11 in a closing direction 91 and an opening direction 92 different from the closing direction 91. The closing direction 91 in this embodiment refers to the direction in which the drawer is closed, and is In the rear, the opening direction 92 is parallel and opposite to the closing direction 91, which refers to the direction in which the drawer is opened, and is the front. This embodiment takes the sliding of the drawer as an example for illustration, but in actual implementation, as long as it is a drawer or furniture that can move along a one-way track, this technology can be applied. The slide rail adjustment device of this embodiment includes a fixing member 2, a receiving member 3, a pushing member 4, a back fastener 5, and an elastic mechanism 6.

The fixing member 2 is interlocked and protrudingly coupled to one side of the moving rail unit 12. The fixing member 2 is fixed to the moving rail unit 12 by, for example, but not limited to, welding.

The accommodating member 3 has an annular shape and defines an insertion space 30 into which the fixing member 2 extends, and the accommodating member 3 includes a first wall 31 and a second wall 32 spaced apart from each other. The thickness t1 of the first wall 31 along the closing direction 91 is greater than the thickness t2 of the second wall 32 along the closing direction 91. The accommodating member 3 is detachably sleeved on the fixing member 2. And in FIGS. 1 and 2, the accommodating member 3 is sleeved on the fixing member 2 in such a manner that the first wall 31 faces the opening direction 92 and the second wall 32 faces the closing direction 91, but the implementation It can also be installed in other directions, which will be explained later.

The pushing member 4 includes a body 41 installed on the fixed rail unit 11, and an pushing block 42 connected to the body 41 and exposed outside the fixed rail unit 11. The main body 41 has a connecting portion 411 connected to one end of the elastic mechanism 6.

The reverse fastener 5 can reciprocate in the closing direction 91 and the opening direction 92, and the reverse fastener 5 can pivot. The anti-fastener 5 has a first section 51 and a second section 52 that is bent and connected to the first section 51. As the anti-fastener 5 moves to different positions, the anti-fastener 5 can be pivoted to a different state, and then is completely hidden in the fixed rail unit 11 (as shown in Figures 1 and 2), or the second section 5 will 2 is exposed outside the fixed rail unit 11 (as shown in Figures 3 and 4).

The elastic mechanism 6 connects the fixed rail unit 11 and the pushing member 4 to accumulate elastic force and provide a return elastic force in the opening direction 92. The elastic mechanism 6 includes a plurality of springs 61 extending along the closing direction 91. One end of each spring 61 is fixed to the fixed rail unit 11, and the other end is connected to the coupling portion 411 of the main body 41 of the pushing member 4.

When in use, the moving rail unit 12 moves in the closing direction 91, which can drive the drawer to close. Conversely, when the moving rail unit 12 moves in the opening direction 92, it can drive the drawer to open. 1 to 4, when the moving rail unit 12 moves from the open state of FIG. 1 toward the closing direction 91 to the position of FIG. 2, the fixing member 2 and the accommodating member 3 also move together, and when the accommodating member 3 When the second wall 32 pushes against the ejecting block 42 of the ejecting member 4, the accommodating member 3 then pushes the ejecting member 4 and moves in the closing direction 91, and moves to the position of FIG. 4 through the position of FIG. 3. The elastic mechanism 6 is driven by the accommodating member 3 to stretch, thereby accumulating elastic force. The anti-fastening member 5 is transformed from the state of FIGS. 1 and 2 originally hidden in the fixed rail unit 11 to the state of FIG. 3, and the second section 52 of the anti-fastening member 5 is partially exposed, and finally converted to the state of FIG. 4 , The second section 52 exposes a large part, at this time The second section 52 cooperates with the pushing block 42 of the pushing member 4 and is located in front of and behind the accommodating member 3 respectively. The accommodating member 3 and related components have been locked and positioned, and the slide rail adjusting device is in a position Close the locked state, the drawer is closed and positioned.

Referring to Figures 5 and 6, the accommodating member 3 can also be mounted on the fixing member 2 in another way. As shown in Figure 5, the accommodating member 3 is such that the first wall 31 faces the closing direction 91, and the second wall 31 faces the closing direction 91. The wall 32 is installed in the opening direction 92. When the drawer is closed, the moving rail unit 12 is also pushed in the closing direction 91, the first wall 31 of the accommodating member 3 will move against the pushing member 4, and finally the accommodating member 3, the pushing member 4 and the back buckle The element 5 and other elements are converted to the closed and locked state of Fig. 6, and the drawer is closed and positioned. The mounting direction of the accommodating member 3 in Figs. 5 and 6 is different from that in Figs. 1 to 4, and the differences are explained as follows.

Refer to FIG. 7, which is a comparison between FIG. 4 (placed above FIG. 7) and FIG. 6 (placed below FIG. 7). 4 shows that the second wall 32 of the accommodating member 3 faces the closing direction 91 and the pushing block 42 of the pushing member 4, and Fig. 6 shows that the first wall 31 of the accommodating member 3 faces the closing direction 91 With the push-out block 42 of the push-out piece 4. Since the thickness t1 of the first wall 31 in the closing direction 91 is greater than the thickness t2 of the second wall 32 in the closing direction 91, when the drawer and the moving rail unit 12 are to be moved from the open state to the closed and locked state, as shown in the figure 1 Change to the state of FIG. 4, the movable distance of the movable rail unit 12 in the closing direction 91 is relatively long, relatively, when the state of FIG. 5 is switched to the state of FIG. 6, the movable rail unit 12 is movable in the closing direction 91 The distance is relatively short, so in the closed and locked state of Fig. 4 and Fig. 6, the distance between one end surface of the moving rail unit 12 of Fig. 4 and one end surface of the fixed rail unit 11 The distance A (FIG. 7) is smaller than the distance B (FIG. 7) between the end surface of the movable rail unit 12 of FIG. 6 and the end surface of the fixed rail unit 11, through the distance between the movable rail unit 12 and the fixed rail unit 11 The change of the displacement distance (equivalent to changing the length of the overlapping part between the moving rail unit 12 and the fixed rail unit 11) can adjust the size of the door gap. When the drawer is closed and positioned, the door gap in Figure 4 is smaller than the door gap in Figure 6 The length of the overlapping portion between the movable rail unit 12 and the fixed rail unit 11 is longer in FIG. 4 than in FIG. 6. The distance C marked in Fig. 7 is greater than the distance D.

In summary, when the moving rail unit 12 and the fixed rail unit 11 are in the closed state, the displacement of the moving rail unit 12 relative to the fixed rail unit 11 overlaps with each other. The change of the distance between the insertion space 30 and the ejection member 4 from the accommodating member 3 which is inserted into the fixing member 2 as the center. For example, as shown in FIG. 4, the thickness of the accommodating member 3 toward the closing direction 91 is relatively small. For example, as shown in FIG. 6, the thickness of the accommodating member 3 toward the closing direction 91 is relatively large; The dimension (thickness) of the receiving member 3 in the opening direction 92 is relatively large, and the dimension (thickness) of the receiving member 3 in the opening direction 92 in FIG. 6 is relatively small. Specifically, in this embodiment, the accommodating member 3 has a first wall 31 and a second wall 32 of different sizes (thickness), and the accommodating member 3 is of a replaceable design, and its installation direction can be changed. , The accommodating member 3 is changed corresponding to the two dimensions of the closing direction 91 and the opening direction 92, so that the length of the overlapping part between the moving rail unit 12 and the fixed rail unit 11 is increased or decreased, Advance And can adjust the size of the door gap. Moreover, the element of the present invention has a simple structure and low cost, especially the purpose of changing the door gap is achieved through the accommodating member 3, which has a simple structure.

Referring to Fig. 8, a second embodiment of the slide rail adjustment device of the present invention has substantially the same structure as the first embodiment, except that the slide rail adjustment device of the second embodiment omits the first embodiment. Anti-fastener 5 (Figure 6). Since the anti-fastener 5 (FIG. 6) is not the focus of the present invention, it can be omitted.

9 and 10, a third embodiment of the slide rail adjusting device of the present invention has substantially the same structure as the first embodiment, and is also installed on the cabinet. The slide rail mechanism 1 of the third embodiment is commonly known as the three-section steel ball rail, so in addition to the fixed rail unit 11 and the moving rail unit 12, it also includes a fixed rail unit 11 and the moving rail unit. The middle rail unit 13 between 12 is used to extend the overall length of the slide rail mechanism 1 after unfolding, but it is not necessary to provide the middle rail unit 13 during implementation. The slide rail adjustment device of the third embodiment also includes the fixing member 2, the accommodating member 3, the pushing member 4, and the elastic mechanism 6. Although the structural appearance of these elements is slightly different from that of the first embodiment, The functions are roughly the same. Wherein, the fixing member 2 is interlocked and protrudingly coupled to the inner side of the moving rail unit 12 so as to extend into the insertion space 30 of the receiving member 3. The thickness t1 of the first wall 31 of the accommodating member 3 in the closing direction 91 is also greater than the thickness t2 of the second wall 32 in the closing direction 91. Further, the accommodating member 3 further has a first fixing portion 33 connected to the first wall 31, and a second fixing portion 34 connected to the second wall 32, the first fixing portion 33 and the second fixing portion 34 is used to hook and buckle the push-out piece 4.

In the state of FIG. 9, the first wall 31 of the accommodating member 3 is installed in the closing direction 91 and the second wall 32 is installed in the opening direction 92, and the opened state of the drawer is displayed. When the drawer is closed, the moving rail unit 12 is pushed in the closing direction 91, and the fixing member 2 in turn drives the receiving member 3 to follow. The first wall 31 and the first fixing portion 33 of the accommodating member 3 gradually approach the pushing member 4, and the first fixing portion 33 and the pushing member 4 are buckled together, so that the first wall 31 can drive the pushing member 4 Following the movement, finally the accommodating member 3, the ejecting member 4 and other components are converted to the closed and locked state of FIG. 10, and the drawer is closed and positioned.

Referring to FIG. 11, the accommodating member 3 is installed in another way, so that the first wall 31 of the accommodating member 3 faces the opening direction 92 and the second wall 32 faces the closing direction 91. When the drawer is closed, the second fixing portion 34 of the accommodating member 3 is hooked and combined with the pushing member 4. The distance A in FIG. 11 is smaller than the distance B in FIG. 10, so the door gap in FIG. 11 is smaller than the door gap in FIG. .

Referring to Fig. 12, a fourth embodiment of the slide rail adjusting device of the present invention has substantially the same structure as the first embodiment, and is also installed on the cabinet. The difference is that the slide rail mechanism 1 of the fourth embodiment is commonly known as a hidden bottom drag rail, which is different from the horse-riding draw rail of the first embodiment and the three-section steel ball rail of the third embodiment. The slide rail adjustment device of the fourth embodiment also includes the fixing member 2, the receiving member 3, the pushing member 4, the anti-buckle member 5 and the elastic mechanism 6. It is also because the thickness t1 of the first wall 31 of the accommodating member 3 is different from the thickness t2 of the second wall 32 and the mounting direction can be changed, so that the accommodating member 3 faces the closing direction 91 and towards the opening Corresponding changes in the two dimensions of the direction 92 to make The length of the overlapping portion between the movable rail unit 12 and the fixed rail unit 11 is increased or decreased, so that the size of the door gap can be adjusted.

However, the above are only examples of the present invention. When the scope of implementation of the present invention cannot be limited by this, all simple equivalent changes and modifications made in accordance with the scope of the patent application of the present invention and the content of the patent specification still belong to This invention patent covers the scope.
