Description

Technical Field

[0001] This utility model relates to the field of travel storage, and in particular to a retractable travel storage bag. Background Technology

[0002] Travel bags, as a common carrier of belongings, have traditionally focused on continuous improvement in terms of capacity, durability, and comfort, greatly facilitating travel. However, they still have the following shortcomings:

[0003] Fixed volume: Traditional backpacks use a fixed volume design, which cannot flexibly adjust the items carried according to the travel itinerary, resulting in problems such as empty packs and the need to add storage bags for carrying items;

[0004] Swaying of items: Traditional backpacks have a fixed volume design. During travel, the items in the backpack will be consumed, resulting in gaps. As a result, the items will sway, affecting the comfort of carrying them and increasing the risk of damage to the items.

[0005] To address this, a retractable travel storage bag is proposed. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing fixed-volume designs, which cannot flexibly adjust the items carried according to the travel itinerary, and the gaps caused by the consumption of items, thereby affecting the comfort during the carrying process and increasing the risk of damage to the carried items. Therefore, a retractable travel storage bag is proposed.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A retractable travel storage bag includes a backpack storage section, a backpack telescopic section fixedly connected to the top of the backpack storage section, a backpack opening section fixedly connected to the top of the backpack telescopic section, and limit mechanisms provided on both sides of the backpack storage section to limit the telescopic length of the backpack telescopic section.

[0009] The limiting mechanism includes a guide box and a limiting block fixed to one side of the backpack storage section. A rack is slidably connected inside the guide box, and multiple limiting grooves are provided on the surface of the rack. A guide cylinder is fixedly connected to one side of the guide box, and a square hole communicating with the guide cylinder is opened on one side of the guide box. The inner wall of the guide cylinder is provided with a first step, a second step, and a third step. A right-angle limiting block is slidably connected to the inner wall of the guide cylinder. A connecting rod is fixedly connected to one side of the right-angle limiting block. A spring is sleeved on the outer circumference of the connecting rod. The two ends of the spring abut against the right-angle limiting block and the third step respectively through spring seats. One end of the connecting rod is rotatably connected to a buckle through a bearing.

[0010] When the right-angle limiting block abuts against the second step, the bottom of the right-angle limiting block abuts against the limiting groove of the rack to lock the extension and retraction of the backpack telescopic part. When the right-angle limiting block abuts against the first step, the locking of the backpack telescopic part is released by rotating the buckle so that one side abuts against one side of the limiting block.

[0011] In one possible design, a handle is fixedly connected to the top of the backpack opening section, and a zipper is provided on the outside of the backpack opening section.

[0012] In one possible design, two pairs of T-shaped guide rails are fixedly connected to one side of the backpack storage section. T-shaped sliders are slidably fitted on the outer side of each T-shaped guide rail, and the same auxiliary bag is fixedly connected to one side of the same pair of T-shaped sliders.

[0013] In one possible design, two shoulder straps are fixedly installed on one side of the backpack's storage section.

[0014] In one possible design, the spring is a compression spring, whose preload causes the right-angle limiting block to normally abut against the second step.

[0015] In one possible design, one end of the T-shaped guide rail is provided with a circular protrusion, and one end of the T-shaped slider is provided with a matching circular groove, the two working together to prevent the T-shaped slider from disengaging.

[0016] In one possible design, the T-shaped guide rail and T-shaped slider are made of polyamide or polyester.

[0017] In one possible design, the backpack's stretchable section is made of nylon.

[0018] In this application, the first step is to pull the buckle outward, drive the right-angle limiting block to slide along the inner wall of the guide cylinder until it abuts against the first step, and then rotate it so that one side of the buckle abuts against the limiting block, thereby releasing the lock on the telescopic part of the backpack.

[0019] The second step is to unzip the backpack, place the items inside, and then close the zipper.

[0020] Third, rotate the buckle to release it from the limiting block. Under the preload of the spring, the right-angle limiting block returns to the second step.

[0021] Fourth step, press the backpack opening part downwards, push the rack downwards along the guide box, and the backpack telescopic part will retract step by step;

[0022] Fifth step: When the backpack gap is eliminated (the item displacement is less than 2mm), the bottom of the right-angle limit block and the limit groove of the rack lock the rack's travel.

[0023] Step 6: When there are many items, the secondary bag can be slidably installed. It slides between the T-shaped guide rail and the T-shaped slider, and the circular protrusions engage with the corresponding circular slots to lock the secondary bag in place.

[0024] Step 7: Apply a separation force of >5N to deform the T-shaped guide rail and T-shaped slider made of polyamide or polyester material. The circular protrusion will disengage from the circular slot, allowing the T-shaped slider to disengage and remove the secondary package.

[0025] Beneficial effects: In this utility model, the retractable travel storage bag, through the coordinated use of components such as the backpack storage part, shoulder straps, backpack telescopic part, and backpack opening part, can flexibly change the volume of the backpack by extending and retracting the backpack telescopic part, thereby flexibly adjusting the items carried according to the travel itinerary;

[0026] In this utility model, the retractable travel storage bag, through the coordinated use of components such as limiting blocks, buckles, connecting rods, guide boxes, racks, limiting grooves, springs, right-angle limiting blocks, and backpack telescopic parts, can control the telescopic length of the backpack through the limiting mechanism, thereby adapting to changes in backpack contents during travel, changing the backpack volume to eliminate backpack gaps, preventing items from shaking, improving comfort during carrying, and reducing the risk of damage to carried items;

[0027] In this invention, the telescopic length of the backpack is controlled by a limiting mechanism, which allows for flexible changes in the backpack's volume. This enables flexible adjustments to the items carried according to the travel itinerary, adapting to changes in items during the trip, improving comfort during carrying, and reducing the risk of damage to carried items.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0037] In one embodiment, reference is made to... Figures 1-7 A storage bag includes: a backpack storage part 1, a backpack telescopic part 3 fixedly connected to the top of the backpack storage part 1, the backpack telescopic part 3 adopts a nylon corrugated tube structure, which can be axially extended and retracted to dynamically change the backpack volume, thereby flexibly adjusting the items carried according to the travel itinerary; a backpack opening part 4 fixedly connected to the top of the backpack telescopic part 3; and limit mechanisms are provided on both sides of the backpack storage part 1 to limit the extension length of the backpack telescopic part 3.

[0038] In this utility model, the limiting mechanism includes a guide box 9 and a limiting block 6 fixed to one side of the backpack storage part 1. A rack 10 is slidably connected inside the guide box 9. The surface of the rack 10 is provided with multiple limiting grooves 1001. A guide cylinder 13 is fixedly connected to one side of the guide box 9. A square hole communicating with the guide cylinder 13 is opened on one side of the guide box 9. A first step 1301, a second step 1302 and a third step 1303 are provided on the inner wall of the guide cylinder 13. A right-angle limiting block 12 is slidably connected to the inner wall of the guide cylinder 13. A connecting rod 8 is fixedly connected to one side of the right-angle limiting block 12. A spring 11 is sleeved on the outer circumference of the connecting rod 8. The two ends of the spring 11 abut against the right-angle limiting block 12 and the third step 1303 respectively through spring seats. A buckle 7 is rotatably connected to one end of the connecting rod 8 through a bearing. One side of the backpack opening part 4 is fixed to the rack 10.

[0039] In particular, when the right-angle limiting block 12 abuts against the second step 1302, the bottom of the right-angle limiting block 12 abuts against the limiting groove 1001 of the rack 10 to lock the extension stroke of the backpack telescopic part 3. When the right-angle limiting block 12 abuts against the first step 1301, the buckle 7 is rotated so that one side abuts against the side of the limiting block 6, thereby releasing the lock on the backpack telescopic part 3. The extension length of the backpack telescopic part 3 can be controlled by the limiting mechanism, thereby adapting to the changes in backpack items during the trip, changing the backpack volume to eliminate backpack gaps, preventing items from shaking, improving comfort during carrying and reducing the risk of damage to carried items.

[0040] In addition, a handle 401 is fixedly connected to the top of the backpack opening part 4, and a zipper is provided on the outside of the backpack opening part 4.

[0041] It should be noted that two pairs of T-shaped guide rails 14 are fixedly connected to one side of the backpack storage section 1. T-shaped sliders 15 are slidably fitted on the outer side of each T-shaped guide rail 14. The same auxiliary bag 5 is fixedly connected to one side of the same pair of T-shaped sliders 15.

[0042] This application can be used in the field of travel organization, or in other fields applicable to this application.

[0043] In another embodiment, reference Figures 1-7 A retractable travel storage bag is applied to the field of travel storage. Two shoulder straps 2 are fixedly installed on one side of the backpack storage part 1. The shoulder straps 2 are equipped with D-ring buckles, which can adjust the length of the shoulder straps 2 to suit people of different body types.

[0044] In this utility model, the spring 11 is a compression spring, and its preload force causes the right-angle limiting block 12 to normally abut against the second step 1302, ensuring that during the travel process, when the backpack vibrates, the right-angle limiting block 12 will not disengage from the position of the second step 1302, and will always maintain the locking state of the rack 10.

[0045] In particular, one end of the T-shaped guide rail 14 is provided with a circular protrusion 1401, and one end of the T-shaped slider 15 is provided with a matching circular slot 1501. The two work together to restrict the T-shaped slider 15 from detaching, preventing the backpack from shaking up and down during the journey. If the T-shaped slider 15 detaches, the secondary bag 5 will be thrown out, increasing the safety and stability of carrying.

[0046] It should be noted that the T-shaped guide rail 14 and T-shaped slider 15 are made of polyamide or polyester. When a separation force of >5N is applied, the T-shaped guide rail 14 and T-shaped slider 15 made of polyamide or polyester are deformed, and the circular protrusion 1401 disengages from the circular slot 1501, which allows the T-shaped slider 15 to disengage, making it easier to remove the secondary bag 5 and to access the items inside the secondary bag 5 at any time. The backpack telescopic part 3 is made of nylon, which is not easily damaged after repeated folding, thus improving the service life of the backpack telescopic part 3.

[0047] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
