[0048] The present invention provides a guide rail assembly 100.

[0049] Refer to Figures 1 to 5, in the embodiment of the present invention, the guide rail assembly 100 includes a support base 10, a moving body 20, and sliding rollers 30. The support base 10 is provided with a receiving cavity 10a and a relief opening 121 communicating with the receiving cavity 10a. The support base 10 is provided with a first guiding portion 11; the moving body 20 is provided with a second guiding portion 21. The moving body 20 is slidably connected to the support base 10 and is located in the receiving cavity 10a so that the second guiding portion 21 is in movable abutment with the first guiding portion 11; the sliding rollers 30 are rotatably connected to the moving body 20 and are located in the receiving cavity 10a; the moving body 20 slides relative to the support base 10, and the first guiding portion 11 drives the second guiding portion 21 to lift, so as to drive at least a part of the sliding rollers 30 to be exposed outside the relief opening 121.

[0050] Among them, the support base 10 is provided with a receiving cavity 10a mainly for supporting and protecting the moving body 20 and the sliding rollers 30, so that the guide rail assembly 100 is integrally arranged, which is convenient for moving and installation. At the same time, the shape of the support base 10 can be rectangular or circular, which is not limited in this application as long as it can be adapted to the shape of the moving body 20. In addition, in order to improve the stability of the support of the support base 10, the material of the support base 10 can be a metal material, such as: aluminum material, aluminum alloy material, copper material, copper alloy material, iron material, stainless steel material; of course, it can also be a plastic material, such as: ABS, POM, PS, PMMA, PC, PET, etc. The support base 10 is provided with a relief opening 121. The device 3000 is placed on one side of the support base 10 where the relief opening 121 is provided. The opening shape of the relief opening 121 can be square, and the side length of the relief opening 121 is greater than the diameter of the sliding rollers 30, so that the sliding rollers 30 can be completely exposed outside the relief opening 121. Of course, the sliding rollers 30 can also be partially exposed outside the relief opening 121, which can be specifically selected by those skilled in the art. The moving body 20 can slide relative to the support base 10. In order to improve the sliding efficiency, it can also be connected by sliding methods such as sliders and slide rails.

[0051] The guide rail assembly 100 of the technical solution of the present invention movably abuts the first guide part 11 of the support base 10 and the second guide part 21 of the mobile body 20. In this way, when the device 3000 is transported to the support base 10, the mobile body 20 slides relative to the support base 10, so that the first guide part 11 drives the second guide part 21 to be lifted, so that the sliding roller 30 located in the accommodating cavity 10a of the support base 10 is synchronously driven to be exposed from the yield opening 121 of the support base 10, and then rolls and abuts against the device 3000 located on the support base 10, so that the device 3000 can be translated on the support base 10. After the device 3000 moves to a suitable position, the mobile body 20 is driven to slide relative to the support base 10 again, so that the sliding roller 30 falls back into the accommodating cavity 10a, thereby ensuring that the device 3000 can be stably placed on the support base 10. That is, the sliding roller 30 can be raised or lowered as needed. Without the help of additional cabinet tooling, it can not only meet the movement requirements of the device 3000 during disassembly and assembly, but also ensure that the friction required for fixing the device 3000 is not reduced. At the same time, it avoids the excessive space required for disassembly and assembly, reduces the disassembly and assembly time of the device 3000, and improves the installation efficiency of the device 3000.

[0052] Reference Figures 7 to 10 In one embodiment of the present application, the first guide portion 11 is a guide slope arranged in the accommodating cavity 10a corresponding to the make way opening 121, and the second guide portion 21 is movably abutted against the guide slope and moves along the extension direction of the guide slope so that the second guide portion 21 is lifted or lowered relative to the cavity 10a.

[0053] It is understood that the support base 10 is provided with a support surface 124 for supporting the device 3000, and the guide bevel is arranged at an angle to the support surface 124. By providing the guide bevel and simultaneously movably contacting the second guide portion 21 with the guide bevel, the second guide portion 21 can be relatively raised or lowered under the guidance of the guide bevel, thereby synchronously driving the movable bracket and the sliding roller 30 to rise or fall to meet the needs of the user. This arrangement is relatively convenient and fast, easy to maintain, and at the same time, it makes the movement between the first guide portion 11 and the second guide portion 21 more stable. It should be noted that the movable bracket uses an external force to push the second guide portion 21 upward along the guide bevel, thereby exposing the sliding roller 30 outside the clearance opening 121 and facilitating movement of the device 3000. Once the device 3000 has moved to the appropriate position, the external force is removed, causing the second guide portion 21 and the sliding roller 30 to descend along the guide bevel under the action of their own weight and the weight of the device 3000, allowing the sliding roller 30 to fall back into the accommodating cavity 10a. Alternatively, the second guide portion 21 can be configured as a guide bevel facing the surface of the first guide portion 11, thereby allowing the second guide portion 21 to be elevated relative to the first guide portion 11 under the guidance of the guide bevel. The specific selection can be made by those skilled in the art.

[0054] Furthermore, the mobile body 20 is also provided with a rotating shaft 22, and the second guide part 21 is a guide roller, which is sleeved on the outer peripheral surface of the rotating shaft 22 and rolls against the guide bevel. It can be understood that the guide roller can be the same as the sliding roller 30 to facilitate production and installation. By providing the second guide part 21 with a guide roller, and then sleeved on the rotating shaft 22 of the mobile body 20, the guide roller can roll along the guide bevel to reduce the friction during movement, improve the efficiency of lifting and lowering, and facilitate operation. It should be noted that the first guide part 11 and the second guide part 21 can also be matched through a gear and a rack, so that the first guide part 11 can also achieve the effect of driving the second guide part 21 to lift. The specific setting can be made by those skilled in the art according to the specific situation and will not be elaborated here.

[0055] Further, the number of the rotating shafts 22 is two, the two rotating shafts 22 are arranged at intervals, the guiding roller is sleeved on the outer peripheral surface of one of the rotating shafts 22, and the sliding roller 30 is sleeved on the outer peripheral surface of the other rotating shaft 22. Wherein, by arranging two rotating shafts 22 to be respectively used for connecting the guiding roller and the sliding roller 30, it is convenient for the two to be installed separately in the early stage and disassembled and repaired separately in the later stage, and the operation is more convenient. It should be noted that the distance between the two rotating shafts 22 arranged at intervals is set to avoid interference between the sliding roller 30 and the guiding roller during rotation, and specifically, it can be set by those skilled in the art according to specific situations. The position of the rotating shaft 22 for connecting to the sliding roller 30 is higher than the position of the rotating shaft 22 for connecting to the auxiliary roller, so that the sliding roller 30 is more convenient to move out of the way opening 121.

[0056] Optionally, the number of the guide inclined surfaces is two, the two guide inclined surfaces are connected to the support base 10 and are respectively located on the left and right sides of the sliding direction of the moving body 20, and the sliding roller 30 is sleeved on the outer peripheral surface of the rotating shaft 22; the number of the guiding rollers is two, the two guiding rollers are sleeved on the outer peripheral surface of the rotating shaft 22 and are respectively located on the opposite sides of the sliding roller 30, and one guiding roller is in rolling contact with one guide inclined surface. Wherein, by arranging two guide inclined surfaces on the left and right sides of the sliding direction of the moving body 20 and making rolling contact through the two guiding rollers, the forces on the moving body 20 and the sliding roller 30 during the lifting and lowering processes are relatively balanced, and the sliding roller 30 and the guiding roller are sleeved on the same rotating shaft 22, saving the internal space of the support base 10 and effectively reducing the weight and cost of the lifting guide rail.

[0057] In an embodiment of the present application, refer to Figure 4 , Figure 7 , Figure 11 and Figure 12The support base 10 includes a cover body 12 and a lower shell 13. The lower shell 13 is connected to the cover body 12 to enclose the accommodation cavity 10a. The cover body 12 is used to carry the device 3000. The cover body 12 is provided with the relief opening 121. The moving body 20 is slidably connected to the lower shell 13. The guiding inclined surface is connected to the surface of the lower shell 13 facing the relief opening 121. It can be understood that the cover body 12 and the lower shell 13 can be connected by means of snap connection or screw connection to enclose the accommodation cavity 10a, so as to facilitate later disassembly and repair. The cover body 12 is provided with a support surface 124 for supporting the device 3000, and the relief opening 121 penetrates the support surface 124, so that the sliding roller 30 can pass through the relief opening 121 and protrude above the support surface 124 to lift the device 3000, making it convenient to move the device 3000. The support surface 124 can be arranged as a flat surface, so that when the device 3000 is placed on the support surface 124, it is not easy to shake, and at the same time, the contact area between the device 3000 and the cover body 12 is ensured, thereby ensuring the stability of the device 3000 after installation.

[0058] Further, the lower shell 13 includes a bottom plate 131 and two support side plates 132. The two support side plates 132 are connected to opposite sides of the bottom plate 131. The two support side plates 132 are connected to the cover body 12. The guiding inclined surface is connected to the bottom plate 131. Among them, the bottom plate 131 and the two support side plates 132 can be an integral structure, which not only omits the previous assembly process, but also ensures the stability of the overall structure of the lower shell 13. The two support side plates 132 are connected to opposite sides of the bottom plate 131, so that the opposite sides of the cover body 12 can be respectively connected to the two support side plates 132 to ensure the overall force balance of the cover body 12. It can be understood that the cover body 12 is provided with two limit side plates corresponding to the two support side plates 132. By connecting the two limit side plates to the two support side plates 132 respectively, the arrangement of the two limit side plates can limit the moving direction of the moving body 20 to prevent the moving body 20 from shaking left and right during the moving process, so as to ensure the stability of the movement of the moving body 20.

[0059] Optionally, referring to Figure 12, the guide rail assembly 100 further includes two limit plates 40. The two limit plates 40 are connected to the cover body 12 and are respectively located at opposite ends in the sliding direction of the moving body 20 for abutting and limiting the moving body 20. Among them, the two limit plates 40 can be an integral structure with the cover body 12. Of course, the two limit plates 40 can also be connected to the cover body 12 by means of screws or buckles. By arranging the two limit plates 40 at opposite ends in the sliding direction of the moving body 20, the moving stroke of the moving body 20 is limited, so as to avoid the hard abutment between the sliding roller 30 and the inner wall surface of the cover body 12 provided with the relief opening 121 due to too large a movement amplitude of the moving body 20, which may cause damage. In addition, the setting of the two limit plates 40 also improves the overall structural strength of the cover body 12 to ensure the stability of the support base 10 for supporting the device 3000.

[0060] Optionally, referring to Figure 11 , the guide rail assembly 100 further includes two limit blocks 50. The two limit blocks 50 are connected to the surface of the cover body 12 provided with the relief opening 121 and are respectively located on the left and right sides in the sliding direction of the moving body 20. The two limit blocks 50 are used for abutting and limiting the device 3000. Among them, when the sliding roller 30 protrudes from the relief opening 121, by arranging the two limit blocks 50 to abut against the left and right sides of the device 3000, it is avoided that the device 3000 deviates from the guide rail assembly 100 during the movement, thereby ensuring the stability of the movement of the device 3000.

[0061] In an embodiment of the present application, referring to Figures 2 to 5 , the guide rail assembly 100 further includes a transmission screw 60. The support base 10 is provided with a threaded through hole 122 communicating with the accommodation cavity 10a. The transmission screw 60 passes through the threaded hole and abuts against the moving body 20 to push the moving body 20 to slide relative to the support base 10. Among them, by providing the threaded through hole 122 in the support base 10 and passing the transmission screw 60 through the threaded through hole 122 to push the moving body 20 to move, this operation method is relatively convenient. At the same time, the cooperation of the transmission screw 60 and the threaded through hole 122 enables the transmission screw 60 to stably stop at a fixed position after moving axially, so that it can stably abut against the moving body 20, and further enables the sliding roller 30 to be stably exposed outside the relief opening 121. This transmission method is relatively stable and fast.

[0062] In one embodiment, when loading the device 3000 into the cabinet, first rotate the transmission screw 60 clockwise. The transmission screw 60 will move forward along its axis and push the moving body 20, causing the guiding roller to move obliquely upward along the inclined guide surface until the moving body 20 contacts the limiting plate 40. At this time, the sliding roller 30 will expose a certain height above the support base 10. Then, the device 3000 is pushed into the cabinet from the external tooling 2000 of the cabinet. Inside the cabinet, the device 3000 moves to the installation position under the action of the sliding roller 30. Finally, rotate the transmission screw 60 counterclockwise. The transmission screw 60 moves backward along its axis, and the moving body 20 and the guiding roller move obliquely downward along the inclined guide surface under the action of their own gravity and the gravity of the device 3000 until the moving body 20 contacts another limiting plate 40. At this time, the entire sliding roller 30 is located inside the installation cavity, and the device 3000 is in full contact with the support base 10. Installation holes 123 are provided on the support base 10, so that after fastening the device 3000 through the installation screws in the installation holes 123, there will be sufficient frictional force to restrain the device 3000. When it is necessary to remove the device 3000 from the cabinet, the operation opposite to the loading operation can be performed.

[0063] In one embodiment of the present application, referring to Figure 4 , Figure 7 and Figure 8 , the number of the first guiding portions 11 is multiple, and the multiple first guiding portions 11 are arranged at intervals along the sliding direction. The second guiding portion 21 is also provided with multiple corresponding to the first guiding portion 11, and one second guiding portion 21 is in movable abutment with one first guiding portion 11. Among them, the first guiding portion 11 and the second guiding portion 21 are correspondingly provided with multiple to further improve the lifting and lowering speed and stability of the overall moving body 20 and the sliding roller 30. The specific number can be selected by those skilled in the art according to the specific situation and will not be elaborated here.

[0064] Optionally, referring to Figures 2 to 4 , the number of the sliding rollers 30 is multiple, and the multiple sliding rollers 30 are arranged at intervals along the sliding direction of the moving body 20. Among them, in order to further improve the moving speed of the device 3000 on the support base 10, multiple sliding rollers 30 can be provided and arranged at intervals along the sliding direction of the moving body 20 to increase the contact area between the sliding rollers 30 and the device 3000, making it more convenient for the operator to push the device 3000 to move.

[0065] The present invention further provides an installation cabinet 1000, which includes one or more guide rail assemblies 100. Thus, one or more corresponding guide rail assemblies 100 can be arranged in the installation cabinet 1000 according to sliding requirements. The specific structure of the guide rail assembly 100 refers to the above-mentioned embodiments. Among them, the size and quantity of the guide rail assemblies 100 can be selected in the installation cabinet 1000 according to needs. Since the installation cabinet 1000 adopts all the technical solutions of the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be elaborated here one by one.

[0066] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly.
