[0008] The slide bar includes a first slide bar segment and a second slide bar segment, wherein the first slide bar segment is located in the middle and is solid, and the second slide bar segment is located at both ends of the first slide bar segment, wherein the second slide bar segment is a hollow slide bar segment, and the center of the second slide bar is vacuum-set.

[0009] In some embodiments, the translational slide rail includes a shell disposed outside, the shell is divided into an inner shell and an outer shell, a gap is left between the inner shell and the outer shell, and the gap is a vacuum.

[0010] In some embodiments, the inner shell and the outer shell are connected via supporting ribs.

[0011] In some implementations, a length ratio of the second slider segment to the first slider segment is 5:1-2.

[0012] In some implementations, a space is provided between the first slider segment and the second slider segment.

[0013] In some embodiments, the slide grooves are disposed on the upper and lower surfaces and the side surfaces of the fixed slide rail, and the upper and lower inner surfaces and the inner side surfaces of the translational slide rail are disposed with slide bars corresponding to the slide grooves.

[0014] In some embodiments, the shell of the translational slide rail is recessed downward to form a groove, and the extending direction of the groove is the same as the extending direction of the slide bar.

[0015] In some embodiments, the shell of the translational slide rail is an aluminum profile, the interior of the shell is filled with ceramics, and the fixed slide rail is a ceramic fixed slide rail.

[0016] In some embodiments, both ends of the slide groove are provided with limit blocks, and the limit blocks are connected to rubber sheets, and the rubber sheets are detachably connected to the two ends of the slide bar.

[0017] The aluminum silent guide rail of the utility model divides the slide bar into a first slide bar section in the middle and second slide bar sections at both ends, wherein the first slide bar section is a solid slide bar section which can ensure the strength of the slide bar and ensure that the translational slide rail can move stably, and the second slide bar section at the outer end is a vacuum section which can block the noise generated by the first slide bar from being transmitted outwardly, thereby effectively reducing the noise, and the structure is simple and the cost is low.

[0026] This embodiment discloses an aluminum type silent guide rail, such as Figures 1 to 3 As shown, including:

[0027] A fixed slide rail 1, wherein a slide groove 2 is provided on the fixed slide rail 1.

[0028] A translational slide rail 3, the translational slide rail 3 is sleeved on the fixed slide rail 1, the inner wall surface of the translational slide rail 3 is provided with a slide bar 4, the slide bar 4 is slidably connected with the slide groove 2,

[0029] The slide bar 4 on the translational slide rail 3 cooperates with the slide groove 2 on the fixed slide rail 1 , so that the translational slide rail 3 can slide along the fixed slide rail 1 .

[0030] The slide bar 4 includes a first slide bar segment 5 and a second slide bar segment 6, wherein the first slide bar segment 5 is located in the middle and is solid, and the second slide bar segment 6 is located at both ends of the first slide bar segment 5, wherein the second slide bar segment 6 is a hollow slide bar segment 4, and the center of the second slide bar 4 is vacuum-set.

[0031] The slide bar 4 is divided into a first slide bar segment 5 in the middle and second slide bar segments 6 at both ends, wherein the first slide bar segment 5 is a solid slide bar segment 4 to ensure the strength of the slide bar 4 and ensure that the translational slide rail 3 can move stably, and the second slide bar segment 6 at the outer end is a vacuum, which can block the noise generated by the first slide bar segment 5 from being transmitted outward, effectively reducing the noise, and the structure is simple and low in cost.

[0032] Therefore, by dividing the slide bar 4 , the noise generated by the solid slide bar 4 sections can be effectively isolated, and the hollow slide bar 4 sections are vacuum inside and located at the two ends of the slide bar 4 , which can effectively isolate the noise generated by the slide bar 4 .

[0033] In this embodiment, the translational slide rail 3 includes a shell arranged outside, and the shell is divided into an inner shell 7 and an outer shell 8. A gap 13 is left between the inner shell 7 and the outer shell 8, and the gap 13 is a vacuum.

[0034] The outer objects of the translation slide rail 3 are set as an inner shell 7 and an outer shell 8, so that the middle part is set as a vacuum, which can effectively block the noise generated inside the translation slide rail 3.

[0035] In this embodiment, the inner shell 7 and the outer shell 8 are connected by support ribs 9. The main function of the support ribs 9 is to keep the inner shell 7 and the outer shell 8 in a fixed shape and prevent the inner shell 7 and the outer shell 8 from deforming.

[0036] In this embodiment, the length ratio of the second slide bar segment 6 to the first slide bar segment 5 is 5:1-2.

[0037] The second slide bar section 6 that is solidly arranged occupies the majority, so as to ensure that the translational slide rail 3 can slide smoothly. The shorter second slide bar section 6 can isolate noise, and the size of the second slide bar section 6 can be reduced as much as possible.

[0038] In this embodiment, a space is provided between the first slide bar segment 5 and the second slide bar segment 6.

[0039] Since the propagation speed of sound in gas is slow, the first slide bar segment 5 and the second slide bar segment 6 are arranged separately (arranged at an interval of 13 ), which can effectively reduce the sound propagation between the first slide bar segment 5 and the second slide bar segment 6 . Example 2

[0040] This embodiment discloses an aluminum type silent guide rail, such as Figures 1 to 3 As shown, including:

[0041] A fixed slide rail 1, wherein a slide groove 2 is provided on the fixed slide rail 1.

[0042] A translational slide rail 3, the translational slide rail 3 is sleeved on the fixed slide rail 1, the inner wall surface of the translational slide rail 3 is provided with a slide bar 4, the slide bar 4 is slidably connected with the slide groove 2,

[0043] The slide bar 4 on the translational slide rail 3 cooperates with the slide groove 2 on the fixed slide rail 1 , so that the translational slide rail 3 can slide along the fixed slide rail 1 .

[0044] The slide bar 4 includes a first slide bar segment 5 and a second slide bar segment 6, wherein the first slide bar segment 5 is located in the middle and is solid, and the second slide bar segment 6 is located at both ends of the first slide bar segment 5, wherein the second slide bar segment 6 is a hollow slide bar segment 4, and the center of the second slide bar 4 is vacuum-set.

[0045] The slide bar 4 is divided into a first slide bar segment 5 in the middle and second slide bar segments 6 at both ends, wherein the first slide bar segment 5 is a solid slide bar segment 4 to ensure the strength of the slide bar 4 and ensure that the translational slide rail 3 can move stably, and the second slide bar segment 6 at the outer end is a vacuum, which can block the noise generated by the first slide bar segment 5 from being transmitted outward, effectively reducing the noise, and the structure is simple and low in cost.

[0046] Therefore, by dividing the slide bar 4 , the noise generated by the solid slide bar 4 sections can be effectively isolated, and the hollow slide bar 4 sections are vacuum inside and located at the two ends of the slide bar 4 , which can effectively isolate the noise generated by the slide bar 4 .

[0047] In this embodiment, the translational slide rail 3 includes a shell arranged outside, and the shell is divided into an inner shell 7 and an outer shell 8. A gap 13 is left between the inner shell 7 and the outer shell 8, and the gap 13 is a vacuum.

[0048] The outer objects of the translation slide rail 3 are set as an inner shell 7 and an outer shell 8, so that the middle part is set as a vacuum, which can effectively block the noise generated inside the translation slide rail 3.

[0049] In this embodiment, the inner shell 7 and the outer shell 8 are connected by support ribs 9. The main function of the support ribs 9 is to keep the inner shell 7 and the outer shell 8 in a fixed shape and prevent the inner shell 7 and the outer shell 8 from deforming.

[0050] In this embodiment, the length ratio of the second slide bar segment 6 to the first slide bar segment 5 is 5:1-2.

[0051] The second slide bar section 6 that is solidly arranged occupies the majority, so as to ensure that the translational slide rail 3 can slide smoothly. The shorter second slide bar section 6 can isolate noise, and the size of the second slide bar section 6 can be reduced as much as possible.

[0052] In this embodiment, a space is provided between the first slide bar segment 5 and the second slide bar segment 6.

[0053] Since the propagation speed of sound in gas is slow, the first slide bar segment 5 and the second slide bar segment 6 are arranged separately (arranged at an interval of 13 ), which can effectively reduce the sound propagation between the first slide bar segment 5 and the second slide bar segment 6 .

[0054] The slide grooves 2 are arranged on the upper and lower surfaces and the side surfaces of the fixed slide rail 1 , and the upper and lower inner surfaces and the inner side surfaces of the translational slide rail 3 are arranged on the slide bars 4 corresponding to the slide grooves 2 .

[0055] The slide grooves 2 are respectively arranged on the sides of the fixed slide rail 1, which can effectively stabilize the entire translation slide rail 3 and reduce the generation of noise.

[0056] In this embodiment, the shell of the translational slide rail 3 is recessed downward to form a groove 10 , and the extending direction of the groove 10 is the same as the extending direction of the slide bar 4 .

[0057] When the shell of the translational slide rail 3 is sunken downward to form the groove 10 , the groove 10 can effectively disperse the damage of the slide bar 4 of the translational slide rail 3 to the shell.

[0058] In this embodiment, the shell of the translational slide rail 3 is an aluminum profile, the interior of the shell is filled with ceramics, and the fixed slide rail 1 is a ceramic fixed slide rail 1.

[0059] The shell of the translational slide 3 is an aluminum profile, which can effectively reduce the weight of the bottom translational slide 3. After filling with ceramic, the production cost can be reduced and the stability of the translational slide 3 can be ensured. The fixed slide 1 is a ceramic slide, which has less friction and can reduce the generation of noise.

[0060] In this embodiment, both ends of the slide groove 2 are provided with limit blocks 11 , and the limit blocks 11 are connected to rubber sheets 12 , and the rubber sheets 12 are detachably connected to the two ends of the slide bar 4 .

[0061] The limit stopper 11 is used to prevent the slide bar 4 from sliding beyond the limit in the slide groove 2, and the rubber sheet 12 can reduce the generation of noise.
