Description

Technical Field

[0001] The utility model relates to the technical field of racks, in particular to a variable-spacing rack. Background Technique

[0002] Racks mainly belong to the computer field. The design of racks takes into account the different sizes and installation requirements of electronic devices, providing a more flexible layout method; while the traditional rack design is often fixed and difficult to adapt to the installation requirements of different-sized devices. With the diversification of electronic devices and the development of technology, traditional racks appear to be insufficiently flexible in practical applications and cannot meet the requirements of variable hardware configurations and optimized space utilization.

[0003] With the continuous development and update of computer technology, the requirements for the installation and layout of computer hardware devices are getting higher and higher. The fixed-spacing rack design is usually only applicable to devices of specific sizes and cannot adapt to the installation requirements of different-sized devices. At the same time, the fixed-spacing design will cause some spaces to be unable to be effectively utilized, resulting in a waste of space resources. The fixed-spacing design of racks can no longer meet the growing needs.

[0004] For example, common bracket models on the market such as Rack-1K and Rack-1KS. During the use of these racks, it is necessary to fix the internal support plates with bolts or rivets. As a result, when adjusting the spacing between the internal support plates of the rack later, it is necessary to remove the rivets and take down the network device in order to adjust the height spacing of the rack; secondly, during the use of traditional racks on the market, most can only adjust the up-and-down spacing and cannot adjust the horizontal spacing of the rack.

[0005] Therefore, a variable-spacing rack is specifically proposed. Summary of the Invention

[0006] The purpose of the utility model is to provide a variable-spacing rack. With the cooperation of multiple structures such as a main bevel gear, a secondary bevel gear, a grooved pulley, and a threaded rod, the height of the left support plate and the right support plate can be adjusted, so as to change the space size for installing electronic devices. Furthermore, the spacing between the left support plate and the right support plate in the horizontal state of the up-and-down position can be gradually increased or decreased. Moreover, with the cooperation of the above multiple structures, the height of the left support plate and the right support plate can be adjusted separately to meet the requirements for installing electronic devices, so as to solve the problems raised in the above background technique.

[0034] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0035] Please refer to Figures 1 to 7 , the present utility model provides a technical solution:

[0036] A variable-spacing rack includes a base 1. Above the base 1, there are horizontally arranged left support plates 21 and right support plates 22. At the positions of the front left corner of the lower end of the left support plate 21 and the rear right corner of the lower end of the right support plate 22, there are vertically arranged threaded rods 104. On the circumferential surfaces of the threaded rods 104, two groove wheels 105 are fixedly installed. On the circumferential surfaces of the two groove wheels 105, a conveyor belt 106 is rotatably installed. Among them, on the circumferential surface of the threaded rod 104 below the corner of the right support plate 22, a secondary bevel gear 10 is fixedly installed. The secondary bevel gear 10 meshes with a primary bevel gear 9. At the center position of the rear end of the primary bevel gear 9, a drive motor 8 is fixedly installed.

[0037] At the positions of the corners of the upper end surface of the base 1, vertically arranged first columns 101 are fixedly installed. Inside the first column 101 at the front right corner position of the upper end surface of the base 1 and the first column 101 at the rear left corner position of the upper end surface of the base 1, sliding rods 102 are slidably installed. The lower ends of the two threaded rods 104 are rotatably installed inside the remaining two first columns 101.

[0038] At the position of the right corner of the rear end face of the base 1, a vertically arranged L-shaped rack bar 2 is fixedly installed. Around the outside of the L-shaped rack bar 2, a sliding box 3 is slidably installed. At the rear end face of the sliding box 3, two servo motors 4 are fixedly installed. On the output shafts of the two servo motors 4, gears 41 are fixedly installed. The gears 41 mesh with the tooth grooves on both sides of the L-shaped rack bar 2. On both sides of the front end face of the sliding box 3, two horizontally arranged adjusting motors 5 are fixedly installed. On the output shafts of the adjusting motors 5, first screws 51 are fixedly installed. On the circumferential surfaces of the first screws 51, threaded sliders 6 are rotatably installed. On the front end faces of the two threaded sliders 6, connecting rods 7 are rotatably installed. The rear end of the drive motor 8 is rotatably connected to one end of the two connecting rods 7 away from the threaded sliders 6.

[0039] By adopting the above technical solution, during use, the servo motor 4 is started, and the output shafts of the two servo motors 4 rotate in opposite directions, so that the sliding box 3 can slide horizontally on the L-shaped rack bar 2, and thus the sliding box 3 can drive structures such as the adjustment motor 5 to move synchronously. Under the action of the sliding box 3, the main bevel gear 9 can move to the lower part of the left support plate 21 and the right support plate 22 whose spacing needs to be adjusted. Then, under the action of the output shaft of the adjustment motor 5, the first screw rod 51 can drive the threaded slider 6 to slide, so that the connecting rod 7 can push the driving motor 8 closer to the secondary bevel gear 10. Then, driven by the driving motor 8, the main bevel gear 9 is engaged with the secondary bevel gear 10; the driving motor 8 is started, and the output shaft of the driving motor 8 drives the main bevel gear 9 to rotate synchronously, so that the main bevel gear 9 can drive the secondary bevel gear 10 to rotate, and then the secondary bevel gear 10 drives the threaded rod 104 and the groove wheel 105 to rotate synchronously, and the groove wheel 105 drives the conveyor belt 106 to rotate, and then the conveyor belt 106 drives the groove wheel 105 and the threaded rod 104 at the lower end corner of the left support plate 21 to rotate synchronously. Thus, under the action of the threaded rod 104, the convex chute 28 can move up and down, and then the left support plate 21 and the right support plate 22 can move up and down, so that the spacing between the left support plate 21 and the right support plate 22 at the middle position and the bottom base 1 can be changed. Secondly, during the use process, since the secondary bevel gear 10 will move up and down synchronously, therefore, during the use process, under the adjustment of devices such as the controller, it is necessary to adjust the height of the sliding box 3 at any time driven by the servo motor 4 to change the height of the main bevel gear 9 to avoid the situation that the main bevel gear 9 and the secondary bevel gear 10 are not engaged; compared with the traditional frame on the market, this device will not have the situation that one end corner is higher and the other end corner is lower during use.

[0040] Specifically, as Figures 1 to 7 shown, support blocks 26 are fixedly installed on the front and rear end faces of the left support plate 21 and the right support plate 22. A first motor 27 is fixedly installed on the right side of the support block 26 on the front end face of the right support plate 22. An adjustment rod 271 is fixedly installed on the output shaft of the first motor 27. The left end of the adjustment rod 271 passes through the support block 26 on the front end face of the left support plate 21. Sliding installation grooves 23 are formed on the adjacent end faces of the left support plate 21 and the right support plate 22. A left sliding plate 24 is slidably installed inside the sliding installation groove 23 of the left support plate 21, and a right sliding plate 25 is slidably installed inside the sliding installation groove 23 of the right support plate 22.

[0041] At the positions near the edges of the lower end faces of the adjacent ends of the left support plate 21 and the right support plate 22, two sliding platforms 29 are fixedly installed. At the upper ends of the sliding rod 102 and the threaded rod 104, convex sliding grooves 28 are rotatably installed. The sliding platforms 29 are slidably installed inside the convex sliding grooves 28. On the outer sides of the four convex sliding grooves 28 close to the base 1, support connecting rods 30 are fixedly installed. At the upper ends of the four support connecting rods 30, second columns 103 are fixedly installed. Inside two of the second columns 103 in a diagonal state, the sliding rod 102 is slidably installed, and inside the other two second columns 103 in a diagonal state, the threaded rod 104 is rotatably installed. Electronic devices 40 are placed on the upper end faces of the base 1, the left support plate 21, and the right support plate 22.

[0042] By adopting the above technical solution, during use, start the first motor 27, and the output shaft of the first motor 27 will drive the adjusting rod 271 to rotate synchronously, so that the adjacent left support plate 21 and right support plate 22 can be in a separated state. Then, during the use process, the lower end of the second column 103 is not fixedly connected to the left support plate 21 and the right support plate 22. Therefore, during the sliding process of the left support plate 21 and the right support plate 22, the second column 103 will not affect the movement of the left support plate 21 and the right support plate 22. Because most of the traditional machine frames on the market can only adjust the vertical distance during use, the horizontal distance between devices cannot be adjusted, and heat will be generated between adjacent two devices, affecting the heat dissipation between devices. However, when this device is in use, with the cooperation of the above structure, the distance between adjacent devices can be enlarged or reduced. Secondly, after the distance between devices with smaller heat dissipation is increased, the same network devices can be placed again. There are few horizontal distance adjustment mechanisms for traditional machine frames on the market. During the use of the above device, sliding installation grooves 23 are formed on the adjacent end faces of the left support plate 21 and the right support plate 22. On the side faces far away from each other inside the sliding installation grooves 23, springs are fixedly installed. Under the action of the springs, the adjacent ends of the left sliding plate 24 and the right sliding plate 25 can be attached together, so that more space for placing devices can be obtained between the left support plate 21 and the right support plate 22, and thus one more device can be added. With the cooperation of the above structure, for the horizontal state of the same height as the above machine frame barrel, one more network device can be added, and thus the overall machine frame can add quite a number of network devices. Therefore, compared with the traditional machine frames on the market, this machine frame can reduce and increase devices according to actual needs to meet the needs of network devices.

[0043] Working principle: First, under the action of the servo motor 4, the sliding box 3 can drive the driving motor 8 to operate synchronously. Then, the output shaft of the driving motor 8 drives the main bevel gear 9 to rotate synchronously, so that the main bevel gear 9 drives the secondary bevel gear 10 to rotate synchronously.

[0044] Driven by the secondary bevel gear 10, the groove wheel 105 and the conveyor belt 106 can rotate synchronously, so that the tops of the two threaded rods 104 push the convex sliding groove 28 to move up and down, and further make the left support plate 21 and the right support plate 22 move up and down synchronously.

[0045] Secondly, under the action of the first motor 27, the adjusting rod 271 can rotate synchronously, so that the left support plate 21 and the right support plate 22 can gradually move away from or close to each other.

[0046] Then, under the action of the left sliding plate 24 and the right sliding plate 25, another electronic device 40 can be placed, or the distance between two adjacent electronic devices 40 can be increased or decreased.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
