DETAILED DESCRIPTION
[0032] The preferred embodiments of the utility model will be described in detail below in conjunction with the drawings, wherein the drawings form a part of this application and are used together with the embodiments of the utility model to explain the principles of the utility model, but are not used to limit the scope of the utility model.
[0033] One specific embodiment of the utility model discloses a connecting device of slide rail type seat, which is used for connecting the slide rail type seat with the track, as shown in the figure, comprising a fixed box 1, a drive wheel 2, an upper limiting assembly 3 and a lower limiting assembly 4, one end of the fixed box 1 is connected with the seat body 6, the other end is connected with the upper limiting assembly 3 and the lower limiting assembly 4, the upper limiting assembly 3 can be connected with the upper limiting rod 51 of the slide rail 5 and slide along the upper limiting rod 51, the lower limiting assembly 4 can be connected with the lower limiting rod 52 of the slide rail 5 and slide along the lower limiting rod 52, the drive wheel 2 is connected with the upper limiting assembly 3, the drive wheel 2 can move along the track 53 of the slide rail 5, so as to drive the seat to move. Figures 1-2 Further, the fixed box 1 comprises a box body 11, an upper fixed end 12, a guide rail 13, a spring 14 and a lower fixed end 15, the upper fixed end 12 and the lower fixed end 15 are arranged at two ends of the box body 11, the guide rail 13 and the spring 14 are arranged in the box body 11, one end of the guide rail 13 is connected with the upper fixed end 12, the other end is connected with the lower fixed end 15; the upper limiting assembly 3 comprises an upper sliding block 33; the lower limiting assembly 4 comprises a lower sliding block 43, the upper sliding block 33 and the lower sliding block 43 are connected with the guide rail 13 and can move along the guide rail 13, the spring 14 is arranged between the upper sliding block 33 and the lower sliding block 43 and is sleeved with the guide rail 13.
[0034] Further, as shown in the figure,
[0035] Further, as shown in the figure, Figure 3As shown, the fixed box 1 also includes a traction line 16. An upper pulley 331 is provided in the upper sliding block 33, and a lower pulley 431 is provided in the lower sliding block 43. The upper pulley 331 and the lower pulley 431 are connected by the traction line 16. One end of the traction line 16 is connected to the lower pulley 431, and the other end is fixed on the lower fixed end 15 after wrapping around the upper pulley 331. The length of the traction line 16 is fixed and it is made of non-elastic material.
[0036] For example, the traction line 16 is a steel wire traction line.
[0037] Furthermore, such as Figures 1-2 As shown, the upper limit assembly 3 also includes an upper clamp 31 and an upper connecting shaft 32. The upper clamp 31 can be connected to the upper limit rod 51. The upper clamp 31 is connected to the upper sliding block 33 through the upper connecting shaft 32. The upper connecting shaft 32 is connected to the drive wheel 2 through a bearing seat. The lower limit assembly 4 also includes a lower clamp 41 and a lower connecting shaft 42. The lower clamp 41 can be connected to the lower limit rod 52. The lower clamp 41 is connected to the lower sliding block 43 through the lower connecting shaft 42.
[0038] Preferred, such as Figure 2 As shown, the upper clamp 31 and the lower clamp 41 are respectively provided with a first roller and a second roller. The upper clamp 31 is connected to the upper limit rod 51 through the first roller, and the lower clamp 41 is connected to the lower limit rod 52 through the second roller, thereby increasing the sliding performance of the connecting device and the slide rail 5 and reducing the friction between the connecting device and the slide rail 5.
[0039] Understandably, when the connecting device is not connected, the spring 14 is compressed under the gravity of the upper limit assembly 3, and the upper limit assembly 3 tends to move closer to the upper fixed end 12, but remains fixed due to the restriction of the traction line 16. When the upper clamp 31 is connected to the upper limit rod 51, the gravity of the seat 6 causes the box 11 to move downward, causing the upper slider 33 to move closer to the upper fixed end 12, which stretches the spring 14. At the same time, the length of the traction line 16 between the upper pulley 331 and the lower fixed end 15 increases, which reduces the length of the traction line 16 between the upper pulley 331 and the lower pulley 431. This causes the traction line 16 to pull the lower pulley 431 upward, and the lower slider 43 moves upward along the guide rail 13 under the elastic force of the traction line 16 and the spring 14, causing the lower clamp 41 to press against the lower limit rod 52 and connect with the lower limit rod 52.
[0040] When it is necessary to disassemble the sliding seat, lift the seat body 6 to move the box body 11 upward. The length of the traction line 16 between the upper pulley 331 and the lower fixed end 15 decreases, and the spring 14 is compressed, resulting in an increase in the length of the traction line 16 between the upper pulley 331 and the lower pulley 431. Under the action of the traction line 16 and the spring 14, the distance between the upper pulley 331 and the lower pulley 431 increases, thereby enabling the upper clamp 31 to be removed from the upper limit rod 51 and the lower clamp 41 to be removed from the lower limit rod 52.
[0041] Preferred, such as Figure 4 As shown, a first linear bearing 332 is also provided inside the upper sliding block 33. The upper sliding block 33 is connected to the guide rail 13 through the first linear bearing 332, thereby reducing the friction between the guide rail 13 and the upper sliding block 33 and improving the stability of sliding.
[0042] Preferred, such as Figure 5 As shown, a second linear bearing 432 is also provided inside the lower sliding block 43. The lower sliding block 43 is connected to the guide rail 13 through the second linear bearing 432, thereby reducing the friction between the guide rail 13 and the lower sliding block 43 and improving the stability of sliding.
[0043] Furthermore, such as Figure 4 As shown, the upper connecting shaft 32 includes a first stabilizing bearing 321, a first limiting pin 322, a first limiting ring 323, and an upper shaft housing 324. The first stabilizing bearing 321 is disposed inside the upper shaft housing 324 and connected to the upper shaft housing 324 through a bearing seat. The upper clamp 31 is connected to the first stabilizing bearing 321, so that the upper clamp 31 can adjust the connection angle during the sliding process with the upper limit rod 51. The first limiting ring 323 is provided on the first stabilizing bearing 321 and rotates with the first stabilizing bearing 321. The first limiting pin 322 is provided on the upper shaft housing 324. The first limiting ring 323 cooperates with the first limiting pin 322. The first limiting pin 322 can limit the rotation of the first limiting ring 323, thereby controlling the rotation range of the first stabilizing bearing 321 and preventing the upper clamp 31 from rotating too much, affecting the stability of the connection with the upper limit rod 51. This ensures that the upper clamp 31 remains stably connected to the upper limit rod 51 and prevents the upper clamp 31 from separating from the upper limit rod 51 during the turning process.
[0044] like Figure 5As shown, the lower connecting shaft 42 includes a second stabilizing bearing 421, a second limiting pin 422, a second limiting ring 423, and a lower shaft housing 424. The second stabilizing bearing 421 is disposed inside the lower shaft housing 424 and connected to the lower shaft housing 424 through a bearing seat. The lower clamp 41 is connected to the second stabilizing bearing 421, thereby allowing the lower clamp 41 to adjust its connection angle during the sliding motion of the lower limiting rod 52. The second limiting ring 423 is provided on the second stabilizing bearing 421, and the second limiting pin 422 is provided on the lower shaft housing 424. The second limiting ring 423 cooperates with the second limiting pin 422 to control the rotation range of the second stabilizing bearing 421, preventing the lower clamp 41 from rotating too much and affecting the stability of its connection with the lower limiting rod 52. This ensures that the lower clamp 41 remains stably connected to the lower limiting rod 52 and prevents the lower clamp 41 from separating from the lower limiting rod 52 during turning.
[0045] Compared with the prior art, the connecting device of this utility model for a sliding rail seat allows the seat body 6 to be connected and disassembled with the sliding rail 5 by setting a fixing box 1, an upper limit component 3, and a lower limit component 4. This simplifies operation, facilitates storage of the sliding rail seat, and saves space. The weight of the seat body 6 causes the upper slider 33 to move towards the upper fixed end 12, thereby connecting the lower clamp 41 to the lower limit rod 52 under the elastic force of the traction line 16 and the spring 14. This makes operation simple and convenient. The first stabilizing bearing 321, the first limiting pin 322, and the first limiting ring 323 ensure a stable connection between the upper clamp 31 and the upper limit rod 51, preventing separation during turns. Similarly, the second stabilizing bearing 421, the second limiting pin 422, and the second limiting ring 423 ensure a stable connection between the lower clamp 41 and the lower limit rod 52, preventing separation during turns.
[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
