Description

Technical Field

[0001] This utility model relates to the field of outdoor transportation equipment technology, and in particular to an outdoor goods trailer. Background Technology

[0002] Outdoor gear trailers (also known as camping trailers or camping vehicles) are portable transportation tools designed specifically for outdoor activities. They are mainly used to transport camping equipment (such as tents, folding chairs, cooking utensils, etc.), children's supplies, or heavy supplies. Their core function is to reduce the user's load and adapt to complex terrain. They are commonly used in camping, picnics, fishing, and other similar scenarios.

[0003] How outdoor item trailers work: They are driven manually or electrically, with the power transmitted to the wheels via a gearbox or chain, similar to the steering of a car's front wheels. They are highly stable and suitable for flat terrain. The tiered storage panels are kept level by limiting sleeves and storage limiters to prevent items from slipping off. The adjustable wheel hub height automatically adapts to terrain differences.

[0004] Although traditional outdoor gear trailers feature a foldable design, their structural protection is relatively weak when folded, exposing the inner lining bags for storing items. Traditional inner lining bags are mostly made of ordinary Oxford cloth or canvas, which, while possessing basic abrasion resistance, are susceptible to erosion from ultraviolet rays and rainwater when exposed to the outdoor environment for a long time, leading to fiber embrittlement and reducing the lifespan of the equipment.

An inner lining bag 13 is fixedly connected between the first protective box 1 and the second protective box 4. An mounting shell 18 is fixedly connected to the outer side wall of the first protective box 1. A circular groove is opened through the upper surface of the mounting shell 18. A plug-in shaft 20 is slidably connected to the inner wall of the circular groove. A return spring 21 is sleeved on the outer wall of the plug-in shaft 20. A limiting ring 19 is sleeved on the outer wall of the plug-in shaft 20. A long plate 2 is fixedly connected to the end of the plug-in shaft 20 away from the mounting shell 18.

[0029] A handle 3 is fixedly connected to the side of the long plate 2 away from the plug shaft 20. A first connecting rod 15 is fixedly connected to the inner wall of the first protective box 1. A first folding rod 17 is rotatably connected to the end of the first connecting rod 15 away from the first protective box 1. A second folding rod 16 is rotatably connected to the inner wall of the first protective box 1. Another first connecting rod 15 is fixedly connected to the inner wall of the second protective box 4. Another first folding rod 17 is rotatably connected to the end of the other first connecting rod 15 away from the second protective box 4. Another second folding rod 16 is rotatably connected to the inner wall of the second protective box 4.

[0030] Example 2

[0031] Reference Figure 1-5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: the end of the second folding rod 16 away from the first protective box 1 is rotatably connected to the end of another second folding rod 16 away from the second protective box 4; the outer wall of the second folding rod 16 is rotatably connected to the outer wall of the first folding rod 17; the outer wall of another second folding rod 16 is rotatably connected to the outer wall of another first folding rod 17; a triangular fixing shell 14 is fixedly connected to the outer wall of the second folding rod 16; the outer wall of the triangular fixing shell 14 is fixedly connected to the outer wall of the inner lining bag 13; a telescopic pull rod 9 is hinged to the outer wall of the first protective box 1; and a pull handle 12 is fixedly connected to the end of the telescopic pull rod 9 away from the first protective box 1.

[0032] The outer wall of the second protective housing 4 is provided with a cross groove 22. The inner wall of the cross groove 22 is slidably connected to a cross slider 23. The side of the cross slider 23 away from the cross groove 22 is fixedly connected to a movable hinge seat 5. A movable shaft 6 is hinged inside the movable hinge seat 5. The outer wall of the first protective housing 1 is fixedly connected to a fixed hinge seat 8. A movable bushing 7 is hinged inside the fixed hinge seat 8. The outer wall of the movable shaft 6 is slidably connected to the inner wall of the movable bushing 7. A bolt is rotatably connected to the outer surface of the movable bushing 7. A matching insertion hole is opened through the outer surface of the movable shaft 6. A second connecting rod 10 is fixedly connected to the upper surface of the movable shaft 6. A plug-in shaft cylinder 11 is fixedly connected to the end of the second connecting rod 10 away from the movable shaft 6. The inner diameter of the plug-in shaft cylinder 11 matches the outer diameter of the plug-in shaft 20.

[0033] The remaining structure is the same as that in Example 1.

[0034] During use, when the trailer is unfolded, as the first protective housing 1 and the second protective housing 4 unfold, the cross slider 23 slides within the cross groove 22 to the bottom of the second protective housing 4, causing the movable hinge seat 5 to move. This causes the movable shaft 6 to slide synchronously within the movable bushing 7, simultaneously unfolding the first connecting rod 15, the second folding rod 16, and the first folding rod 17, and unfolding the inner lining bag 13. When the trailer is fully unfolded, the trailer is fixed by inserting the bolts on the movable bushing 7 into the holes on the movable shaft 6, thereby fixing the positions of the first protective housing 1 and the second protective housing 4, so that the trailer is fixed in the unfolded state, preventing the trailer from accidentally retracting and affecting its use.

[0035] During use, when the trailer is not in use, rotate the bolt on the movable bushing 7 to disengage it from the insertion hole on the movable shaft 6, allowing the first protective box 1 and the second protective box 4 to fold into a complete box, housing the first connecting rod 15, the second folding rod 16, the first folding rod 17, and the inner lining bag 13. Pull the long plate 2 upward by the handle 3, causing the insertion shaft 20 to move upward in the mounting shell 18. As the first protective box 1 and the second protective box 4 fold, the movable shaft 6 slides within the movable bushing 7, causing the second connecting rod 10 to move, which in turn moves the insertion shaft cylinder 11 to directly below the insertion shaft 20. After releasing the handle 3, the insertion shaft 20 is pushed into the insertion shaft cylinder 11 by the force of the return spring 21, thus connecting and fixing the first protective box 1 and the second protective box 4. This facilitates outdoor carrying and transfer, while also protecting the inner lining bag 13 from damage and extending the trailer's service life.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
