Description

Technical Field

[0001] The utility model belongs to the technical field of carrying tools, and in particular relates to a backpack-combined carrying tool. Background Art

[0002] A carrying gear is a piece of equipment used to carry items. It usually consists of a back frame, straps and other parts, which can help people carry various items more conveniently and comfortably. The design of a carrying gear is to meet the needs of different scenarios, such as military operations, outdoor adventures, travel, etc. It can be adjusted according to the type, quantity and weight of the items to ensure safety and comfort.

[0003] For example, a Chinese patent with authorization announcement number CN212574432U discloses a backpack for carrying tools, which can adjust the position of an extension plate according to needs to adapt to different types of carrying tools, thereby improving the adjustment ability of the backpack.

[0004] When using the carrying gear to move, users will encounter different situations. For example, when doing sports that require large body movements such as rock climbing, the body needs more room and flexibility. At this time, raising the center of gravity of the carrying gear can reduce interference with leg movements and make your movements more relaxed and comfortable.

[0005] When traveling on rugged mountain roads, muddy trails, or taking long journeys, lowering the center of gravity of the carrying gear can increase its stability. A low center of gravity makes the whole body more balanced, and it is not easy to lose balance and fall due to uneven ground.

[0006] However, the existing carrying tools usually have a relatively simple structure, and the placement position of the cargo is relatively fixed. It is difficult to adjust the center of gravity position of the carrying tool and the cargo combination according to the different needs of users, and it cannot well adapt to the different needs of users.

Specific embodiments

[0023] In order to make the purpose and advantages of the present utility model clearer, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present utility model, and does not strictly limit the scope of protection specifically claimed by the present utility model.

[0024] As Figures 1-4 shown, a back frame combined carrying device includes a back frame body 1 and a storage rack 5. Two back straps 2 are fixedly connected to the front side of the back frame body 1, and the back frame body 1 can be carried on the user's back through the two back straps 2.

[0025] The core of this technical solution lies in that the storage rack 5 is adjustably fixedly connected to the rear side of the back frame body 1. The height of the storage rack 5 at the rear side of the back frame body 1 is adjustable, and the storage rack 5 can be locked at different height positions at the rear side of the back frame body 1. By assembling the storage rack 5 at different height positions at the rear side of the back frame body 1, the center of gravity position of the goods on the upper side of the storage rack 5 can be adjusted together, so that by assembling the storage rack 5 at different height positions on the back frame body 1, the center of gravity position of the carrying device and the goods combination can be adjusted according to the user's needs, better meeting the different needs of the user.

[0026] There are various ways to adjust the height of the storage rack 5. The adjustment method in this technical solution is as shown in 1-2, that is, the two side parts of the back frame body 1 are side plates 3. Vertical sliding frames 4 are vertically slidably connected to the outer sides of the two side plates 3. The storage rack 5 is assembled at the rear sides of the two vertical sliding frames 4. When the two vertical sliding frames 4 move, the storage rack 5 can be driven to move together.

[0027] In order to make the vertical sliding frame 4 more stable, the vertical sliding frame 4 is of a U-shaped structure, and the openings of the two vertical sliding frames 4 face each other, so that both the front side and the rear side of the side plate 3 can provide good limit support for the vertical sliding frame 4, improving the stability of the vertical sliding frame 4.

[0028] And, as Figures 1-3As shown, on one side of the two side plates 3 away from each other, a column of vertically equidistantly arranged lock holes 6 are provided. Two vertically arranged lock rods 9 are installed on the vertical sliding frame 4. The axial distance between the two lock rods 9 is an integer multiple of the axial distance between the two lock holes 6. The lock rod 9 can extend into the interior of any lock hole 6 for locking, so that the position of the vertical sliding frame 4 can be locked.

[0029] At the same time, the lock rod 9 can be a screw, threadedly connected to the interior of the lock hole 6, or as Figures 2-3 shown, it is a round rod, inserted into the interior of the lock hole 6;

[0030] In this technical solution, in order to make the process relatively simple when the position of the vertical sliding frame 4 is switched, the selected lock rod 9 is a round rod. At the same time, in order to ensure the stability of the lock rod 9 after installation, a connecting piece 7 is fixedly connected to the outside of the vertical sliding frame 4. One end of the lock rod 9 inserted into the lock hole 6 is the locking end. The other end of the lock rod 9 passes through the connecting piece 7 and is fixedly connected with a pull ring 8. A top plate 10 is fixedly connected to the outer side of the rod body of the lock rod 9 located inside the connecting piece 7. A return spring 11 is sleeved on the outer side of the lock rod 9. One end of the return spring 11 abuts against the top plate 10, and the other end of the return spring 11 abuts against the inner wall of the connecting piece 7 away from the vertical sliding frame 4. At this time, by pulling the pull ring 8, the pull ring 8 drives the lock rod 9 to be pulled out from the interior of the lock hole 6, and the vertical sliding frame 4 can be vertically slid. After the vertical sliding frame 4 finishes sliding, under the elastic thrust of the return spring 11, the lock rod 9 can be automatically inserted into the interior of the lock hole 6 for locking.

[0031] As Figure 1 and Figure 4 shown, the storage rack 5 can be directly fixedly connected to the rear sides of the two vertical sliding frames 4. In this technical solution, in order to be able to more precisely fine-tune the height of the storage rack 5 after the initial adjustment of the storage rack 5 and better meet the user's needs, the connection method between the vertical sliding frame 4 and the storage rack 5 is selected to be improved. Specifically, two vertically juxtaposed side brackets 12 are fixedly connected to the rear sides of the two vertical sliding frames 4. A screw rod 13 is rotatably connected between the two side brackets 12. A vertical slider 14 is threadedly connected to the outer side of the screw rod 13. The vertical slider 14 is vertically slidably connected to the rear side of the vertical sliding frame 4. The storage rack 5 is fixedly connected to the rear sides of the two vertical sliders 14. At this time, when the user synchronously rotates the two screw rods 13 with both hands, the storage rack 5 can be driven to move vertically, and since only the screw rod 13 needs to be rotated during the movement, the center of gravity position of the goods can be adjusted during the movement.

[0032] Moreover, as Figure 1 and Figure 4As shown in the figure, a protective case 15 is fixedly connected to the side bracket 12. One end of the screw rod 13 is fixedly connected to a large bevel gear 18 located inside the protective case 15. One side of the protective case 15 is rotatably connected to a rotary handle 16. One end of the rotary handle 16 located inside the protective case 15 is fixedly connected to a small bevel gear 17 that meshes with the large bevel gear 18. At this time, through the setting of the small bevel gear 17 and the large bevel gear 18, the position of the rotary handle 16 can be adjusted to the side of the backrest body 1, so as to be more suitable for the user's posture when rotating the rotary handle 16.

[0033] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention are implemented according to the conventional means in the art without special description and limitation.
