[0024] In the existing technology, the on-site placement and arrangement of hoses during the assembly process is very messy, resulting in low space utilization. This leads to material waste during manual assembly and low work efficiency, so it is necessary to improve it.

[0025] To overcome the shortcomings of the prior art, this application provides a hose storage device. Due to the horizontal spacing of multiple sets of slide rails along the frame, each set of slide rails has a slide for the hose to slide. Each set of slide rails is fixed to the frame, and each slide rail extends along the front-back direction of the frame. In the back-to-forehead direction, each set of slide rails extends downward at an angle. Therefore, the slide rails can store the hose. Moreover, the design of the slope angle of the slide allows the hose to slide automatically to the front end without the need to manually push it to the designated position, simplifying the storage operation. There is no need to rummage or go deep into the frame, thus improving the retrieval efficiency.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0027] See Figures 1 to 5 This application provides a storage device for a hose 10. The storage device may include a frame 100 and multiple sets of slide rails 200. The multiple sets of slide rails 200 are arranged laterally at intervals along the frame 100. Each set of slide rails 200 has a slide track 201 for the hose 10 to slide. Each set of slide rails 200 is fixed to the frame 100. Each slide rail 200 extends along the front-rear direction of the frame 100, and in the rear-to-front direction, each set of slide rails 200 extends downward at an angle.

[0028] In this embodiment, the front end and rear end of the slide rail 200 can be used as the take-out end and the insert end, respectively. The tubing 10 has a suspension part 12 that can be suspended by the slide rail 200. The tubing 10 can enter the slide channel 201 from the insert end at the rear end, and the suspension part 12 slides with the slide rail 200, so that the tubing 10 can be movably stored in the slide channel 201.

[0029] Multiple sets of slide rails 200 are distributed laterally along the frame 100, allowing for the simultaneous storage of multiple hoses 10. The lateral spacing prevents the hoses 10 from tangling or being squeezed together, facilitating the categorization and storage of hoses 10 according to specifications, models, or usage scenarios, thus improving storage efficiency and standardization. The laterally spaced slide rails 200 make the position of each hose 10 readily apparent, allowing operators to quickly locate the target hose 10, which is particularly suitable for emergency repair scenarios, shortening search time.

[0030] The horizontally arranged slide rails 200 can expand the storage capacity within the limited width of the frame 100, which is especially suitable for scenarios that require the storage of various hoses 10 (such as industrial equipment maintenance, engineering machinery repair, etc.), reducing space occupation.

[0031] In this embodiment, the slide rail 200 extends in the front-to-back direction (i.e., the depth direction of the frame 100), and the slide 201 is inclined downward, so that the tube 10 slides from back to front by gravity.

[0032] The front end of the slide rail 200 serves as the outlet end for the hose 10, while the rear end serves as the insertion end. During storage, the hose 10 is inserted from the insertion end of the slide rail 200, and it automatically slides to the front end without manual pushing, simplifying storage. When retrieving, the outlet end of the hose 10 is exposed, allowing operators to quickly and directly extract the required hose 10 from the front end of the slide rail 200 without searching or reaching inside the frame 100, thus improving retrieval efficiency.

[0033] In addition, the tilt angle design can prevent the tubing 10 from piling up or getting stuck in the middle of the slide rail 200, ensuring that each tubing 10 slides smoothly along the slide rail 201 to the extraction end, which is especially suitable for storing long tubing 10 and reduces manual handling costs.

[0034] In addition, the slide rail 200 provides a continuous and stable support surface, and the hose 10 extends in a straight line along the slide rail 201 during the sliding process, avoiding excessive bending or folding caused by random stacking, thereby reducing the risk of damage to the internal structure of the hose 10 (such as the reinforcing layer and the inner rubber layer) and extending the service life of the hose 10.

[0035] See Figures 1 to 4 In some embodiments, the frame 100 includes a front crossbeam 110 and a rear crossbeam 120 extending laterally, with the front crossbeam 110 positioned in front of the rear crossbeam 120 and its height lower than that of the rear crossbeam 120. Each set of slide rails 200 has a first connecting portion 210 and a second connecting portion 220 in a rear-to-forward direction, the first connecting portion 210 being fixed to the rear crossbeam 120 and the second connecting portion 220 being fixed to the front crossbeam 110.

[0036] In this embodiment, since the front crossbeam 110 is lower than the rear crossbeam 120, the slide rail 200 is connected to the rear crossbeam 120 and the front crossbeam 110 through the first connecting part 210 and the second connecting part 220. Therefore, the front crossbeam 110 and the rear crossbeam 120 enable the slide rail 200 to tilt from back to front and downward, thereby forming a slide track 201 that tilts from back to front and downward, so that the hose 10 can slide forward under the action of gravity.

[0037] Furthermore, each set of slide rails 200 may also include two main bodies 230, which are arranged laterally at intervals to form a slide track 201 between them. The first connecting part 210 includes two first connecting posts 212, which are correspondingly disposed on the rear side of the two main bodies 230. The second connecting part 220 includes two second connecting posts 222, which are correspondingly disposed on the front side of the two main bodies 230.

[0038] In this embodiment, the two main bodies 230 are laterally spaced to form a slide 201, which serves to clamp and guide the hose 10 from both sides, ensuring that the hose 10 slides in a straight line and preventing it from deviating or rolling off. During the sliding process of the hose 10, the two main bodies 230 restrict its lateral movement to prevent the hose 10 from falling off the slide 201, which is especially suitable for heavy-duty hoses 10 with a large bending radius.

[0039] Two first connecting columns 212 connect the rear sides of the two main bodies 230 to the rear crossbeam 120, respectively. Two second connecting columns 222 connect the front sides of the two main bodies 230 to the front crossbeam 110, respectively.

[0040] For example, the first ends of the two first connecting posts 212 can be welded to the rear sections of the two main bodies 230, and the second ends of the two first connecting posts 212 can be welded to the rear crossbeam 120. The first ends of the two second connecting posts 222 can be welded to the front sections of the two main bodies 230, and the second ends of the two second connecting posts 222 can be welded to the front crossbeam 110.

[0041] Of course, the connection method between the first connecting column 212 and the main body 230 and the rear crossbeam 120 is not limited to welding, and the connection method between the second connecting column 222 and the main body 230 and the front crossbeam 110 is not limited to welding, but can also be threaded connection, snap-fit ​​connection, etc.

[0042] In this embodiment, each main body 230 is fixedly connected to the rear crossbeam 120 and the front crossbeam 110 on the rear side and the front side respectively by the first connecting column 212 and the second connecting column 222. This method can not only improve the fixing effect of the single-sided main body 230, but also enable the main body 230 to form a slide 201 from back to front and downward.

[0043] See Figure 2 and Figure 4 In some embodiments, each set of slide rails 200 may further include two main bodies 230 and two rear ends 240, with the two main bodies 230 arranged laterally at intervals to form a slide track 201 between them. The two rear ends 240 are respectively connected to the rear ends of the two main bodies 230, and the two rear ends 240 are flared.

[0044] For example, both the main body 230 and the rear end 240 can be columnar. The two rear ends 240 are formed at the rear ends of the two main bodies 230 by welding or stamping and bending, and then the two rear ends 240 extend away from each other to form an flared shape.

[0045] Compared to the straight slide rail 201, which requires overcoming a large lateral alignment error, this embodiment designs the rear end of the slide rail 201 as an flared design (such as a trumpet structure), which is conducive to forming a natural guide channel, increasing the inlet area, and reducing the lateral accuracy when inserting the tube 10. The operator does not need to precisely align the slide rail 201 to put the tube 10 into the rear end of the slide rail 200, which greatly improves the placement speed.

[0046] In addition, the flared end can be designed with a rounded transition, which can prevent the end of the hose 10 from making hard contact with the slide rail 200, reduce the risk of scratches on the outer rubber layer or deformation of the metal joint, and has a significant protective effect on the precision joint of the high-pressure hose 10.

[0047] See Figure 2 In some embodiments, each set of slide rails 200 may further include a first body 232, a second body 234, and a first front end portion 250. A slide channel 201 is formed between the first body 232 and the second body 234, and the front end of the first body 232 is further forward than the front end of the second body 234. The first front end portion 250 is connected to the front end of the first body 232 and extends toward the second body 234 to prevent the tube 10 from sliding out of the slide channel 201.

[0048] Since the slide 201 extends from back to front and downwards at an angle, each tube 10 can slide from back to front under its own weight. In this embodiment, the front end of the first body 232 is further forward than the front end of the second body 234, and the first front end 250 is connected to the front end of the first body 232 and extends towards the second body 234. In this way, the first front end 250 can form an "L-shaped" or "hook-shaped" blocking structure, which laterally covers the front opening of the slide 201. When the tube 10 slides to the front end of the slide rail 200, it can be mechanically stopped from sliding down.

[0049] Furthermore, since the first front end portion 250 extends towards the second body 234, that is, extends to the side, it can be designed to open to the side. When the operator wants to remove the tubing 10 from the front, it can be taken out laterally from the side.

[0050] When there are multiple hoses 10 in the slide 201, after the foremost hose 10 is removed from the side, the hoses 10 behind it slide forward in sequence under the action of gravity, so that the foremost hose 10 rests against the first front end 250 again, ready for the operator to pick it up next time.

[0051] See Figure 2 In some embodiments, each set of slide rails 200 may also include a second front end portion 260, which is connected to the front end of the second body 234 and spaced apart from the first front end portion 250 to form a retrieval channel 202 that opens laterally with the first front end portion 250.

[0052] In this embodiment, the second front end 260 is connected to the front end of the second body 234 and is spaced apart from the first front end 250. This eliminates the sharp end of the second body 234, preventing the hose 10 from scraping at that end and protecting the hose 10. On the other hand, the first front end 250 and the second front end 260 form a "double-end clamping" structure, which further improves the lateral limiting ability of the hose 10 compared to relying solely on the single front end of the first front end 250 to block it. This effectively prevents the hose 10 from accidentally slipping out due to vibration or external impact, and is especially suitable for dynamic environments such as vehicles and ships.

[0053] In addition, the width of the pick-up channel 202 can be flexibly adapted to different diameter hoses 10 by adjusting the distance between the two front ends (e.g., a narrow channel for a small diameter hose 10 and a wide channel for a large diameter hose 10). The same slide rail 200 can accommodate hoses 10 with a diameter fluctuation of ±30%, reducing equipment costs.

[0054] See Figure 5 In some embodiments, in the direction from back to front, the angle θ between the extension direction of the slide rail 200 and the horizontal direction is set to be greater than or equal to 10° and less than or equal to 20°. For example, the angle θ can be set to 10°, 15°, 20°, etc.

[0055] In this embodiment, the tilt angle θ of the slide rail 200 is set to the range described above, which is the "critical self-sliding angle" verified by engineering. If the angle is too small (<10°), the component of gravity is insufficient, and the hose 10 may stop due to friction; if the angle is too large (>20°), it will cause the sliding speed to be too fast, increasing the impact of collision with the front end. This range can ensure that the hose 10 slides at a uniform speed of 0.3m / s to 0.6m / s, avoiding damage from sudden impact.

[0056] In some embodiments, in multiple sets of slide rails 200, the lateral width of the slide rail 201 is set to be the same or different.

[0057] When the lateral width of the slide rail 201 is set to be the same, a single width slide rail 201 can share the same set of stamping / injection molds, reducing mold development costs by approximately 40% to 60%, which is especially suitable for mass production scenarios. During installation, there is no need to distinguish between slide rail 200 groups; they can be interchanged at will. Combined with automated assembly equipment (such as robotic arm gripping), installation efficiency is improved and the risk of human error during installation is reduced.

[0058] By setting different lateral widths for the slide rail 201, full-size coverage can be achieved. For example, slide rails 201 of different widths can be designed according to the diameters of different hoses 10 to manage multiple specifications of hoses 10 simultaneously. For example, the width of the narrow slide rail 201 can be designed to be 8~12mm to accommodate micro hoses 10, while the width of the wide slide rail 201 can be designed to be 30~50mm to accommodate heavy-duty hoses 10. This avoids the problem of needing to equip multiple systems with traditional single-width slide rails 200.

[0059] See Figure 1 and Figure 3 In some embodiments, the frame 100 includes a left crossbeam 130 and a right crossbeam 140, with the left crossbeam 130, front crossbeam 110, right crossbeam 140, and rear crossbeam 120 connected end to end to form an installation frame. The frame 100 also includes a plurality of uprights 150 disposed below the installation frame to support it.

[0060] In this embodiment, the left crossbeam 130, the front crossbeam 110, the right crossbeam 140 and the rear crossbeam 120 are connected end to end to form a rectangular or square mounting frame, which constitutes a stable quadrilateral mechanical structure with high torsional stiffness and bending strength, and avoids misalignment of the slide rail 200 due to the twisting of the frame 100.

[0061] The 150 columns can be designed as four, each connected to one of the two crossbeams to evenly support the installation frame.

[0062] See Figure 1 and Figure 3 Furthermore, the frame 100 may also include a plurality of bottom beams 160 connected end to end in sequence, and each bottom beam 160 is disposed between the bottom of two adjacent crossbeams to reinforce the crossbeams.

[0063] See Figure 5 In some further embodiments, there are four columns 150, which are respectively located at the four corners of the mounting frame. The height L of the two front columns 150 is set to be greater than or equal to 20cm.

[0064] In this embodiment, since the front crossbeam 110 and the rear crossbeam 120 are arranged one after the other, and the left crossbeam 130, the front crossbeam 110, the right crossbeam 140 and the rear crossbeam 120 are connected end to end in sequence, and the four columns 150 are respectively set at the four corners of the mounting frame, two of the four columns 150 are located on the front side and are respectively supported on the left and right ends of the front crossbeam 110, and the other two are set on the rear side and are respectively supported on the left and right ends of the rear crossbeam 120.

[0065] In this embodiment, the height L of the two front columns 150 is set to be greater than or equal to 20cm, such as 20cm, 22cm, 30cm, 50cm, etc.

[0066] This design effectively ensures that the height of the front crossbeam 110 supported by the two front columns 150 is sufficient to suspend the hose 10, preventing the hose 10 from dragging on the ground due to insufficient height of the front crossbeam 110, which would affect retrieval and movement.

[0067] Furthermore, since the height of the rear crossbeam 120 is higher than that of the front crossbeam 110, as long as the height of the front crossbeam 110 is sufficient to accommodate the length of the hose 10, the rear crossbeam 120 can naturally also accommodate the length of the hose 10. Therefore, this embodiment limits the height of the two front columns 150 to ensure that the entire mounting frame is high enough to suspend the hose 10, preventing the hose 10 from dragging on the ground and affecting its retrieval and movement.
