[0066] In this document, the term "axial direction" refers to the direction parallel to the central axis of the inner cavity 201 of the sliding groove 200 of the slide rail connection assembly 1. When the slider 100 is accommodated within the inner cavity 201 of the sliding groove 200, the central axis of the slider 100 preferably coincides substantially with the central axis of the inner cavity 201. Therefore, in this case, the term "axial direction" can also refer to the direction parallel to the central axis of the slider 100. Similarly, in this case, "radial direction" refers to the direction parallel to and perpendicular to the central axis of the inner cavity 201 or the slider 100 and intersecting with it, while "circumferential direction" refers to the direction perpendicular to the central axis of the inner cavity 201 or the slider 100 and perpendicular to the radius of the cross section.

[0067] In this article, the terms "inner side", "outer side", "inward", "outward", "proximal", and "far side" are used only to describe the relative positions of the elements.

[0068] The slide rail connection assembly 1 according to an embodiment of the present invention is specifically used for aircraft nacelles, but can also be used in other fields.

[0069] Figure 1 A front view of the slide rail connection assembly 1 according to an embodiment of the present invention is shown. Figure 2 A top view of the slide rail connection assembly 1 according to an embodiment of the present invention is shown. Figure 3 The slide rail connection assembly 1 according to an embodiment of the present invention is shown as follows: Figure 1 The cross-sectional view taken from line AA in the diagram. Figure 4 The slide rail connection assembly 1 according to an embodiment of the present invention is shown as follows: Figure 2 A cross-sectional view taken from line BB in the diagram. Figure 5 An exploded view of the slide rail connection assembly 1 according to an embodiment of the present invention is shown.

[0070] As shown in the figure, the slide rail connection assembly 1 includes a slider 100, a sliding groove 200, and a positioning device 300.

[0071] A slider 100 is received within a sliding groove 200. A positioning device 300 is arranged on the sliding groove 200. More specifically, the slider 100 includes a body 101 and an attachment flange 103 extending from the body 101. The sliding groove 200 includes a groove cavity 201. The body 101 of the slider 100 is received within the groove cavity 201 of the sliding groove 200. The side of the sliding groove 200 has a slot so that the attachment flange 103 of the slider 100 protrudes through the slot. Preferably, the body 101 of the slider 100 is cylindrical, and the groove cavity 201 of the sliding groove 200 is a corresponding cylindrical cavity. This facilitates the movement of the slider 100.

[0072] Preferably, the central axis of the sliding member 100 is substantially coincident with the central axis of the inner cavity 201 of the slide groove.

[0073] More preferably, the attachment flange 103 extends outward in the radial direction of the body 101 of the slider 100.

[0074] like Figure 2 As shown, the attachment flange 103 of the slider 100 is provided with an attachment fastening hole 104 so as to fasten external components to the attachment flange 103 and achieve linear sliding by means of the slider 100.

[0075] It should be understood that, although Figure 2 The attachment flange 103 shown has six attachment fastening holes 104 arranged in a row, but the attachment flange 103 may have more or fewer attachment fastening holes 104, and they do not necessarily have to be arranged in a row but can be arranged in any desired manner.

[0076] The body 101 of the slider 100 includes a first end 101a and a second end 101b opposite to the first end 101a. Preferably, the attachment flange 103 of the slider 100 extends from the first end 101a of the body 101 to its second end 101b, that is, the attachment flange 103 extends the entire length of the body 101.

[0077] It should be understood that, although Figure 2 The attachment flange 103 shown extends the entire length of the body 101, but the attachment flange 103 may extend a portion of the length of the body 101, or be divided into multiple attachment flanges extending from the body 101, or extend beyond the length of the body 101.

[0078] The slider 100, and specifically the body 101 of the slider 100, includes a first positioning hole 110. The sliding groove 200 includes a second positioning hole 210.

[0079] The first positioning hole 110 of the slider 100 can be aligned with the second positioning hole of the sliding groove 200 to form a positioning cavity.

[0080] like Figure 4 As shown, the body 101 of the slider 100 includes a guide groove 102. Preferably, the guide groove 102 is formed in the radial direction. Preferably, a first positioning hole 110 is formed within the guide groove 102. Therefore, the first positioning hole 110 preferably extends in the radial direction.

[0081] Preferably, there is a certain distance between the two ends of the guide groove 102 and the two ends of the main body 101 of the slider 100. For example Figure 4 As shown, the cross-section of the main body 101 is concave.

[0082] More preferably, the guide groove 102 is inclined upward in the direction from the first end 101a of the body 101 to its second end 101b, such as... Figure 4 As shown. In this case, the first positioning hole 110 is formed near the first end 101a of the guide groove 102, close to the main body 101. This inclined structure of the guide groove 102 makes it easier for the positioning device 300 to position and lock the slider 100. This will be described in more detail below.

[0083] As shown in the figure, the positioning device 300 includes a positioning pin 301, an elastic fastener 302, a protective sleeve 303, and a pad 309.

[0084] In this embodiment of the invention, the positioning pin 301 is configured to move within the positioning cavity, and the positioning pin 301 is configured such that when the positioning pin 301 extends through and is fully inserted into the positioning cavity, the positioning pin 301 positions the slider 100 within the sliding groove 200, and when the positioning pin 301 moves away from the inner cavity of the first positioning hole 110 of the slider 100, the slider 100 can move relative to the sliding groove 200, for example, it can slide or rotate circumferentially relative to the sliding groove 200.

[0085] The locating pin 301 includes a vertical rod and a central flange 301f extending outward from the middle of the vertical rod. The central flange 301f of the locating pin 301 divides the locating pin 301 into an upper part 301t and a lower part 301b.

[0086] The lower part 301b of the pin can be inserted into the positioning cavity formed by the first positioning hole 110 of the slider 100 and the second positioning hole 210 of the sliding groove 200. Specifically, when the positioning pin 301 is fully inserted into the positioning cavity, the middle flange 301f of the positioning pin 301 abuts against the upper surface of the sliding groove 200, while the lower part 301b extends through the positioning cavity and protrudes from the lower surface of the sliding groove 200. In other words, the length of the lower part 301b should be longer than the length of the positioning cavity. This design helps the operator determine whether the positioning pin 301 is fully inserted into the positioning cavity.

[0087] The resilient fastener 302 is configured to apply an external force to the locating pin 301 to retain the locating pin 301 within the locating cavity. In particular, the resilient fastener 302 is configured to apply an external force to the intermediate flange 301f of the locating pin 301 to retain the lower portion 301b of the locating pin 301 within the locating cavity.

[0088] Preferably, the elastic fastener 302 is a spring, more preferably a helical spring. The elastic fastener 302 is sleeved on the upper part 301a of the positioning pin 301. One end of the elastic fastener 302 abuts against the middle flange 301f of the positioning pin 301 so as to apply external force to the positioning pin 301.

[0089] The positioning device 300 also includes a protective sleeve 303, which includes a sleeve body and a sleeve lug 303b. The sleeve body surrounds the upper part 301a of the positioning pin 301 and the elastic fastener 302. The top of the sleeve body has an opening so that the upper part 301a of the positioning pin 301 can extend through it.

[0090] The operator can determine whether the positioning pin 301 is inserted into the first positioning hole 110 of the slider 100 by observing the length of the portion of the upper part 301a extending out of the top opening of the sleeve body. More preferably, a scale can be provided on the upper part 301t of the positioning pin 301 to facilitate the operator in determining the position of the positioning pin 301 relative to the slider 100.

[0091] The positioning device 300 also includes a pad 309, which is disposed between the intermediate flange 301f of the positioning pin 301 and the upper surface of the sliding groove 200. In this case, the intermediate flange 301f of the positioning pin 301 abuts against the pad 309. The pad 309 is provided with a third positioning hole 310, a fastening hole for a first fastener 305, and a fastening hole for a second fastener 306. The protective sleeve 303 can be fastened to the pad 309 by the second fastener 306. The pad 309 can be fastened to the sliding groove 200 by the first fastener 305.

[0092] The assembly and operation method of the slide rail connection assembly 1 are briefly described below with reference to embodiments of the present invention:

[0093] 1. Insert the positioning pin 301 into the third positioning hole 310 on the pad 309, put the elastic fastener 302 on the positioning pin 301, then put the protective sleeve 303 on the elastic fastener 302 and press it down so that the upper end of the positioning pin 301 passes through the top opening of the protective sleeve 303, and then fix the protective sleeve 303 and the pad 309 together by the second fastener 306.

[0094] 2. Install the positioning device 300 assembled in step 1 onto the upper surface of the sliding groove 200, that is, insert the lower end of the positioning pin 301 into the second positioning hole 210 of the sliding groove 200, and then fix the positioning device 300 and the sliding groove 200 together by the first fastener 305.

[0095] 3. Insert one end, preferably the second end 101b, of the main body 101 of the slider 100 into the inner cavity 201 of the sliding groove 200, and then lift the positioning pin 301 so that the lower end of the positioning pin 301 is higher than the second end 101b of the main body 101 of the slider 100.

[0096] 4. Push the slider 100 a certain distance, release the lifted positioning pin 301 (preferably falling into the guide groove 102), and slowly push the slider 100 under the guidance of the guide groove 102 until the length of the part of the upper part 301t of the positioning pin 301 extending from the top opening of the protective sleeve 303 becomes significantly shorter. At this time, the positioning pin 301 reaches the position of the first positioning hole 110, and the positioning pin 301 is fully inserted into the positioning cavity formed by the first positioning hole 110 and the second positioning hole 210 under the action of the elastic fixing member 302. One end of the positioning pin 301 extends from the lower surface of the sliding groove 200, thereby realizing the positioning and locking of the slider 100.

[0097] 5. When it is necessary to unlock the slider 100 and slide it relative to the sliding groove 200, simply lift the positioning pin 301 until its lower end leaves the inner cavity of the first positioning hole 110 of the slider 100, and the slider 100 can be unlocked and slide relative to the sliding groove 200. When the slider 100 slides, the lower end of the positioning pin 301 always abuts against the guide groove 102 by means of the "concave" cross-section of the main body 101 and the external force applied by the elastic fixing member 302, and both ends can stop the slider 100.

[0098] Therefore, the slide rail connection assembly 1 according to the embodiment of the present invention has the functions of stopping, locking, and positioning, and at the same time, it has a simple structure, is easy to operate, and is convenient for maintenance. When the positioning pin 301 of the positioning device 300 is fully inserted into the positioning cavity, extends through the positioning cavity, and protrudes from the lower surface of the sliding groove 200, the positioning device 300 can fix the sliding member 100 together with the sliding groove 200. At this time, the elastic fixing member 302 applies an external force to the positioning pin 301 to keep the positioning pin 301 in the positioning cavity, thereby realizing the positioning and locking of the sliding member 100. When it is necessary to unlock the sliding member 100, simply lift the positioning pin 301 so that the lower part 301b of the positioning pin 301 moves away from the inner cavity of the first positioning hole 110, thereby unlocking the sliding member 100, and then the sliding member 100 can move relative to the sliding groove 200. After unlocking the sliding member 100, the sliding of the sliding member 100 can be guided by the cooperation of the guide groove 102 and the positioning pin 301. Then, when the slider 100 slides relative to the sliding groove 200, the lower end of the positioning pin 301 always abuts against the guide groove 102 by means of the concave section of the main body 101 and the external force applied by the elastic fixing member 302, and both ends can stop the slider 100.

[0099] It should be understood that although the positioning device 300 shown in the figure is preferably installed on the upper surface of the sliding groove 200, the positioning device 300 may also be installed on the lower surface of the sliding groove 200.

[0100] It should be understood that although the slide rail connection assembly 1 shown in the figure includes only one positioning device 300, in other embodiments of the present invention, the slide rail connection assembly 1 may include more than one positioning device 300. In this case, the number of the first positioning hole 110 of the slider 100 and the second positioning hole 210 of the sliding groove 200 are increased accordingly.

[0101] In this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, structure, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, structure, or apparatus. Without further limitation, an element defined by the phrase "comprising..." does not exclude the presence of other identical elements in the process, method, structure, or apparatus that includes said element.
