Detailed Description

Before the present invention is described in detail, it should be noted that in the following description, like components are denoted by the same reference numerals.

Referring to fig. 1 and 2, a first embodiment of the sliding rail adjusting device of the present invention is adapted to be mounted on a cabinet, the cabinet includes a cabinet (not shown), a drawer (not shown) capable of opening and closing relative to the cabinet, and a sliding rail mechanism 1. The drawer is provided with a door plate positioned on the front side, and a gap between the door plate and the cabinet body is a door gap. The slide rail mechanism 1 is commonly called a horse riding drawing rail, and includes a fixed rail unit 11 fixedly disposed in the cabinet, and a moving rail unit 12 fixedly coupled to the drawer, wherein the moving 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 of the embodiment is a direction for closing the drawer and is a rear direction, and the opening direction 92 is parallel to and opposite to the closing direction 91 and is a direction for opening the drawer and is a front direction. In the present embodiment, the drawer sliding is taken as an example for explanation, but in actual practice, the present technology can be applied to any drawer or furniture that can move along a one-way rail. The slide rail adjusting device of the present embodiment includes a fixing member 2, a receiving member 3, an ejecting member 4, a fastening member 5, and an elastic mechanism 6.

The fixing member 2 is coupled to the moving rail unit 12 in a protruding manner. The fixing member 2 is fixed to the moving rail unit 12 by, for example, but not limited to, welding.

The accommodating member 3 is annular 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 opposite to each other at an interval. 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. The accommodating part 3 is detachably sleeved on the fixing part 2. In fig. 1 and 2, the accommodating component 3 is sleeved on the fixing component 2 in a manner that the first wall 31 faces the opening direction 92 and the second wall 32 faces the closing direction 91, but the installation in other directions may be adopted in the implementation, which will be described later.

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

The fastener reaction member 5 is reciprocally movable in the closing direction 91 and the opening direction 92, and the fastener reaction member 5 is pivotable. The fastening member 5 has a first section 51 and a second section 52 connected to the first section 51 by bending. As the fastening member 5 moves to different positions, the fastening member 5 can pivot to different states and be completely hidden in the fixed rail unit 11 (as shown in fig. 1 and 2), or the second section 52 thereof can be exposed outside the fixed rail unit 11 (as shown in fig. 3 and 4).

The elastic mechanism 6 connects the fixed rail unit 11 and the ejector 4, and accumulates elastic force and provides 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 combining portion 411 of the body 41 of the pushing member 4.

In use, the movable rail unit 12 moves in the closing direction 91 to drive the drawer to close. Conversely, when the moving rail unit 12 moves in the opening direction 92, the drawer can be driven to open. Referring to fig. 1 to 4, when the moving rail unit 12 moves from the open state of fig. 1 to the position of fig. 2 in the closing direction 91, the fixed member 2 and the accommodating member 3 also move together, and when the second wall 32 of the accommodating member 3 pushes against the pushing block 42 of the pushing member 4, the accommodating member 3 then pushes against the pushing member 4 and also 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, and further accumulates elastic force. The reverse fastening member 5 is switched from the state of fig. 1 and 2 originally hidden in the fixed rail unit 11 to the state of fig. 3, the second section 52 of the reverse fastening member 5 is partially exposed, and finally the state of fig. 4 is switched, the second section 52 is exposed at a large position, at this time, the second section 52 is matched with the pushing block 42 of the pushing member 4 and is respectively positioned in front of and behind the accommodating member 3, the accommodating member 3 and each related component are locked and positioned, the slide rail adjusting device is in a closed and locked state, and the drawer is closed and positioned.

Referring to fig. 5 and 6, the receiving member 3 can be mounted on the fixing member 2 in another way, and fig. 5 shows that the receiving member 3 is mounted with the first wall 31 facing the closing direction 91 and the second wall 32 facing the opening direction 92. When the drawer is closed, the moving rail unit 12 is also pushed toward the closing direction 91, the first wall 31 of the accommodating member 3 pushes the pushing member 4 to move, and finally, the accommodating member 3, the pushing member 4, the fastening member 5 and other components are switched to the closed and locked state shown in fig. 6, so that the drawer is closed and positioned. The installation direction of the receiving member 3 in fig. 5 and 6 is different from that in fig. 1 to 4, and the difference is explained as follows.

Referring to fig. 7, fig. 7 is a comparison of fig. 4 (placed above fig. 7) and fig. 6 (placed below fig. 7) taken together. Fig. 4 shows the second wall 32 of the receiving member 3 facing the closing direction 91 and the pushing block 42 of the pushing member 4, and fig. 6 shows the first wall 31 of the receiving member 3 facing the closing direction 91 and the pushing block 42 of the pushing member 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/moving rail unit 12 is to be moved from the open state to the closed locked state, from fig. 1 to fig. 4, the movable distance of the moving rail unit 12 in the closing direction 91 is longer, and correspondingly, when fig. 5 is moved to fig. 6, the movable distance of the moving rail unit 12 in the closing direction 91 is shorter, so that in the closed locked state of fig. 4 and 6, the distance a (fig. 7) between one end face of the moving rail unit 12 of fig. 4 and one end face of the fixed rail unit 11 is shorter than the distance B (fig. 7) between the end face of the moving rail unit 12 of fig. 6 and the end face of the fixed rail unit 11, by changing the displacement distance of the moving rail unit 12 relative to the fixed rail unit 11 (equivalent to changing the displacement distance between the moving rail unit 12 and the fixed rail unit 11 (fig. 7) The length of the portion overlapping each other), the size of the door slot can be adjusted, when the drawer is closed and positioned, the door slot of fig. 4 is smaller than that of fig. 6, and the length of the portion overlapping each other between the moving rail unit 12 and the fixed rail unit 11 is longer in fig. 4 than in fig. 6.

In summary, when the movable rail unit 12 and the fixed rail unit 11 are in the closed state, the increase or decrease of the length of the overlapping portion between the movable rail unit 12 and the fixed rail unit 11 is caused by the change of the distance between the inserting space 30 into which the accommodating member 3 centered on the fixing member 2 is inserted and the ejector 4. For example, as shown in fig. 4, the thickness of the accommodating member 3 in the closing direction 91 is small, and for example, as shown in fig. 6, the thickness of the accommodating member 3 in the closing direction 91 is large; in contrast, fig. 4 shows a larger dimension (thickness) of the receptacle 3 in the opening direction 92, and fig. 6 shows a smaller dimension (thickness) of the receptacle 3 in the opening direction 92. Specifically, in the present embodiment, the accommodating element 3 has the first wall 31 and the second wall 32 with different sizes (thicknesses), and the accommodating element 3 is designed to be replaceable, so that the installation direction thereof can be changed, and the two sizes of the accommodating element 3 in the closing direction 91 and the opening direction 92 can be changed correspondingly, so that the length of the overlapping portion between the moving rail unit 12 and the fixed rail unit 11 can be increased or decreased, and the size of the door gap can be adjusted. The assembly of the invention is simple in structure and low in cost, and particularly, the purpose of changing the door gap is achieved through the accommodating piece 3, and the accommodating piece 3 has a simple structure.

Referring to fig. 8, a second embodiment of the slide rail adjusting device of the present invention has substantially the same structure as the first embodiment, except that the fastening member 5 (fig. 6) of the first embodiment is omitted. Since the counter fastener 5 (fig. 6) is not the point of improvement of the present invention, it can be omitted.

Referring to fig. 9 and 10, a third embodiment of the slide rail adjusting device of the present invention, which has substantially the same structure as the first embodiment, is also installed on the cabinet. The slide rail mechanism 1 of the third embodiment is a three-section steel ball rail, and therefore includes the fixed rail unit 11, the moving rail unit 12, and a middle rail unit 13 located between the fixed rail unit 11 and the moving rail unit 12, for extending the overall length of the slide rail mechanism 1 after being unfolded, but the middle rail unit 13 is not necessarily provided in implementation. The slide rail adjusting device of the third embodiment also includes the fixing member 2, the accommodating member 3, the pushing member 4, and the elastic mechanism 6, and these components have slightly different structural shapes from those of the first embodiment, but have substantially the same functions. Wherein, the fixing member 2 is linked and protrudingly combined inside the moving rail unit 12 to extend into the inserting space 30 of the accommodating member 3. The thickness t1 of the first wall 31 of the receptacle 3 in the closing direction 91 is likewise greater than the thickness t2 of the second wall 32 in the closing direction 91. Furthermore, the accommodating part 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, and the first fixing portion 33 and the second fixing portion 34 are used for being hooked and combined with the pushing-out part 4.

In the state of fig. 9, the first wall 31 of the receiving member 3 is oriented in the closing direction 91 and the second wall 32 is oriented in the opening direction 92, and the drawer is opened. When the drawer is closed, the movable rail unit 12 is pushed toward the closing direction 91, and the fixing member 2 further drives the accommodating 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, the first fixing portion 33 is buckled with the pushing member 4, so that the first wall 31 can drive the pushing member 4 to move, and finally, the accommodating member 3, the pushing member 4 and other components are switched to the closed locking state shown in fig. 10, and the drawer is closed and positioned.

Referring to fig. 11, the receiving member 3 is installed in another way such that the first wall 31 of the receiving 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, and the distance a in fig. 11 is smaller than the distance B in fig. 10, so that the door gap in fig. 11 is smaller than that in fig. 10.

Referring to fig. 12, a fourth embodiment of the slide rail adjusting device of the present invention, which has substantially the same structure as the first embodiment, is also installed on the cabinet. The difference is that the slide rail mechanism 1 of the fourth embodiment is a so-called hidden trailing rail, which is different from the horse-riding drawn rail of the first embodiment and the three-section steel ball rail of the third embodiment. The slide rail adjusting device of the fourth embodiment also includes the fixing member 2, the accommodating member 3, the pushing member 4, the fastening member 5, and the elastic mechanism 6. Also, the installation direction of the container 3 can be changed as shown in fig. 12 and 13 by changing the thickness t1 of the first wall 31 of the container 3 from the thickness t2 of the second wall 32, so that the two dimensions of the container 3 in the closing direction 91 and the opening direction 92 are changed correspondingly, the length of the overlapping portion between the movable rail unit 12 and the fixed rail unit 11 is increased or decreased, the distance between one end surface of the movable rail unit 12 and one end surface of the fixed rail unit 11 is adjusted from a to B, and the size of the door gap can be adjusted.

It should be noted that, in the implementation of the slide rail adjusting device of the present invention, a plurality of accommodating members 3 with different sizes may be provided, and the slide rail adjusting device may be replaced and assembled according to actual requirements when in use, so as to increase the range of adjustable door gap size.

Referring to fig. 14 and 15, a fifth embodiment of the slide rail adjusting device of the present invention has substantially the same structure as the third embodiment, and the difference is that the accommodating member 3 is provided with only a first fixing portion 33 connected to the first wall 31, but is not provided with the second wall 32 and the second fixing portion 34, and the first fixing portion 33 is used for hooking and combining with the pushing member 4.

When the slide rail adjusting device of the present invention is produced, the accommodating parts 3 with different t1 sizes as shown in fig. 14 and fig. 15 can be provided, and a user can replace the different accommodating parts 3 to adjust the distance a or the distance B, so as to adjust the size of the door gap.

The above description is only an example of the present invention, and the scope of the present invention should not be limited by the above description, and the present invention is also covered by the simple equivalent changes and modifications according to the claims and the content of the description of the present invention.
