Description

Technical Field

[0001] This utility model relates to the field of aluminum tube stacking technology, specifically a layered adjustable aluminum tube stable stacking rack. Background Technology

[0002] In the bicycle manufacturing industry, aluminum tubing is the basic material for core components such as frames and forks. Its production, processing and warehousing all rely on stacking racks for orderly management.

[0003] However, existing aluminum tube stacking racks have some shortcomings. First, the limiting structure of the aluminum tubes can easily hinder their stacking, which not only increases the difficulty of loading but also makes the aluminum tubes prone to scratches due to collisions. Second, since the space of each stacking rack is fixed, gaps may occur between aluminum tubes of different sizes when stacking them, making them prone to shaking. Furthermore, the existing stacking racks lack a separating structure, which can easily cause aluminum tubes to be squeezed and misaligned, making it difficult to align the upper and lower layers when stacking multiple layers, resulting in poor stability.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-7 In this embodiment of the utility model, a layered adjustable aluminum tube stable stacking rack includes multiple columns 1 arranged equidistantly in the horizontal direction, and multiple load-bearing structures 2 arranged along the axial direction of the multiple columns 1. Each load-bearing structure 2 is composed of multiple load-bearing plates 21, and the load-bearing plates 21 are fixedly connected to the opposite columns 1. The other end of each load-bearing structure 2 is fixedly connected to a support structure 3.

[0026] Each layer of the load-bearing structure 2 is provided with a front limiting structure 4 and a rear limiting structure 5 on its front and rear sides respectively. The front limiting structure is a telescopic structure, and the front limiting structure 4 is set on the load-bearing structure 2 through an adjustment structure 6. A partition structure 7 is set between each layer of aluminum tubes. The partition structure 7 is installed on the front limiting structure 4 and the rear limiting structure 5.

[0027] Specifically, such as Figure 1-3 As shown, the support structure 3 includes a connecting plate 31, a support rod 32, and a support column 33. Each bearing plate 21 has a connecting plate 31 on its left and right sides at the front end. The connecting plate 31 is fixedly connected to the bearing plate 21 by bolts. The connecting plate 31 has a connecting hole 311. Each connecting plate 31 has a support rod 32 in the connecting hole 311. The left and right ends of the multiple support rods 32 are fixedly connected to the support column 33.

[0028] Specifically, such as Figure 1 , Figure 2 , Figure 5 and Figure 7 As shown, the rear limiting structure 5 is composed of multiple rear limiting posts 51, which are fixedly connected to the corresponding bearing plate 21.

[0029] Specifically, such as Figure 1-4 As shown, the front limiting structure 4 consists of an adjusting telescopic component 41, a guiding telescopic component 42, and a connecting rod 43. The adjusting telescopic component 41 has two sets, which are set on the left and right sides. The guiding telescopic component 42 has multiple sets, which are set between the two sets of adjusting telescopic components 41. The connecting rod 43 is fixedly connected to the upper end of the adjusting telescopic component 41 and the guiding telescopic component 42.

[0030] The adjustable telescopic assembly 41 includes an inner adjusting limit rod 411, an outer adjusting limit rod 412, an inner positioning hole 413, an outer positioning hole 414, and a positioning pin 415. The outer adjusting limit rod 412 is sleeved outside the inner adjusting limit rod 411. The inner adjusting limit rod 411 has an inner positioning hole 413 on its side wall, and the outer adjusting limit rod 412 has an outer positioning hole 414 on its side wall. The positioning pin 415 can be inserted into the corresponding inner positioning hole 413 and outer positioning hole 414.

[0031] The guide telescopic assembly 42 includes an inner guide limit rod 421 and an outer guide limit rod 422. The outer guide limit rod 422 is sleeved outside the inner guide limit rod 421, and sliders 423 are fixedly connected to both sides of the bottom of the inner guide limit rod 421.

[0032] Before stacking the aluminum tubes, in order to avoid the front limiting structure 4 from obstructing the stacking of the aluminum tubes, the overall height of the front limiting structure 4 is reduced by adjusting the telescopic component 41. During adjustment, the positioning pin 415 is pulled outward, causing the adjusting outer limiting rod 412 to fall, and at the same time, the guiding outer limiting rod 422 is driven to fall. Then, the positioning pin 415 is inserted into the corresponding inner positioning hole 413 and outer positioning hole 414 to make enough space for the aluminum tubes to be stacked.

[0033] The adjustment structure 6 includes an adjustment component 61 and a guide component 62. The adjustment component 61 is located on the left and right support plates 21. Multiple guide components 62 are located on the central support plate 21. The adjustment component 61 consists of a mounting groove 611, a lead screw 612, a screw sleeve 613, a synchronous pulley 614, a synchronous belt 615, and a turntable 616. The left and right support plates 21 are respectively provided with mounting grooves 611. The lead screw 612 is rotatably connected in the mounting groove 611. One end of the lead screw 612 passes through the support plate 21 and is fixedly connected to the synchronous pulley 616. The guide assembly 62 includes a step pulley 614, two synchronous pulleys 614 are fitted with synchronous belts 615, one of the synchronous pulleys 614 is fixedly connected to a turntable 616, a screw rod 612 is threadedly connected to a screw sleeve 613, the screw sleeve 613 is slidably connected to the mounting groove 611, and the top surface of the screw sleeve 613 is fixedly connected to the adjusting inner limit rod 411; the guide assembly 62 includes a slide groove 621 and a slide rail 622, the support plate 21 is provided with a slide groove 621, the two side walls of the slide groove 621 are provided with slide rails 622, and the slider 423 is slidably connected to the slide rail 622.

[0034] After stacking a layer of aluminum tubes, there may be a gap between the front limiting structure 4 and the rear limiting structure 5. In order to prevent the aluminum tubes from shaking inside the layer, the distance between the front limiting structure 4 and the rear limiting structure 5 needs to be adjusted by adjusting the adjusting structure 6. When adjusting, turntable 616 is rotated, and through the transmission of synchronous pulley 614 and synchronous belt 615, the lead screws 612 on both sides are driven to rotate synchronously, so that the screw sleeves 613 on the left and right sides move synchronously, thereby driving the front limiting structure 4 to move as a whole, so that the aluminum tubes are arranged compactly.

[0035] Specifically, such as Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, the partition structure 7 includes a plug groove 71 disposed on the front limiting structure 4. The plug groove 71 is disposed on each set of adjusting telescopic components 41 and guiding telescopic components 42. The adjusting inner limiting rod 411 and adjusting outer limiting rod 412 of each set of adjusting telescopic components 41 are provided with plug grooves 71 opposite to each other. The guiding inner limiting rod 421 and guiding outer limiting rod 422 of each set of guiding telescopic components 42 are provided with plug grooves 71 opposite to each other.

[0036] The partition structure 7 also includes partition plates 72, of which multiple partition plates 72 can be selectively installed on different corresponding insertion slots 71 and rear limiting posts 51. Specifically, the number of partition plates 72 can be selected according to the length of the aluminum tube. The partition plate 72 is made of metal inside and has a rubber layer on the outside. One end of the partition plate 72 is provided with a T-shaped insertion block 73, and the other end is provided with a sleeve through groove 74. The width of the sleeve through groove 74 is the same as the width of the rear limiting post 51, and the length is greater than the length of the rear limiting post 51. The T-shaped insertion block 73 can be inserted into the insertion slot 71, and the sleeve through groove 74 can be sleeved on the rear limiting post 51.

[0037] When installing the partition plate 72, the T-shaped plug block 73 and the plug slot 71 are T-shaped fit, and will not fall off after insertion. The length of the sleeve through slot 74 is greater than that of the rear limit post 51. When the adjustment structure 6 adjusts the movement of the front limit structure 4, the partition plate 72 can slide along the rear limit post 51 in a small range. The setting of the partition plate 72 increases the stability of the multi-layer aluminum tube stacking, and at the same time can prevent the aluminum tube from being damaged or deformed.

[0038] The working principle of this utility model is as follows: The initial state of the front limiting structure 4 of the stacking rack is at the outermost end, in a "maximum open" state, reserving the maximum space for stacking aluminum tubes. Before stacking the aluminum tubes, to avoid the front limiting structure 4 obstructing the stacking, the extension and retraction of the front limiting structure 4 is adjusted by the positioning pin 415 to reduce the height of the front limiting structure 4. Then, the aluminum tubes are stacked one layer in sequence. Due to the different diameters of the aluminum tubes, there may be gaps between the front limiting structure 4 and the rear limiting structure 5 after stacking one layer. To prevent the aluminum tubes from shaking within the layer, the adjusting structure 6 is used to move the front limiting structure 4 towards the rear limiting structure 5, so that the aluminum tubes are arranged compactly. Then, based on the length of the aluminum tube, multiple partition plates 72 are set at certain intervals. The T-shaped plug block 73 at one end of the partition plate 72 is inserted into the plug groove 71, and the sleeve through groove 74 at the other end is fitted onto the rear limit post 51. Since the width of the sleeve through groove 74 is the same as the width of the rear limit post 51, and its length is greater than the length of the rear limit post 51, even when the adjustment structure 6 adjusts the position of the front limit structure 4, the partition plate 72 can still be stably installed on the front limit structure 4 and the rear limit structure 5. After the partition plate 72 is installed, the next layer of aluminum tubes can be stacked, and so on. The setting of the partition plate 72 makes the stacking of aluminum tubes between each layer more stable.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
