[0034] See also Figures 1 to 9 The present invention provides a backpack device 1, which includes a backpack strap connecting device 100. The backpack strap connecting device 100 can be operated with one hand to adjust the backpack strap in two directions of shortening and lengthening, which can improve the problem that the existing backpack strap connecting device 100 needs to be operated with both hands when adjusting.

[0035] See also Figures 1 to 4 The present invention further provides a backpack device 1, which includes: a backpack belt 200 and a backpack belt connecting device 100. The backpack belt connecting device 100 is installed on the backpack belt 200 and connects the backpack belt 200 in a closed loop. If the matching relationship with the operator's shoulder is not considered, the backpack belt 200 in the present invention can be any soft belt-like structure that can be connected to form a closed loop profile through the backpack belt connecting device 100.

[0036] See also Figure 2 and Figure 3 In an example of the carrying device 1 of the present invention, the carrying belt 200 includes a shoulder pad 210 and an adjustment belt 220. The shoulder pad 210 includes a frame 212. The frame 212 is made of a material with a certain hardness, such as plastic, rubber or any other soft material that can form the shape of a human shoulder. In this embodiment, the frame 212 is made of plastic, and the shape of the frame 212 matches the shape of the human shoulder, and is used to cooperate with the shoulder to keep the shoulder pad 210 in a relatively stable state on the shoulder. A connecting buckle 211 is provided at one end of the frame 212, and one end of the adjustment belt 220 is fixedly connected to the connecting buckle 211. The other end of the adjustment belt 220 is connected to the other end of the frame 212 through the carrying belt connecting device 100. A stopper 221 is provided at the end of the adjusting belt 220. The stopper 221 can prevent the adjusting belt 220 from escaping from the carrying belt connecting device 100 during the adjustment process.

[0037] See also Figures 2 to 3 ,as well as Figure 7 The backpack connection device 100 is used to achieve a closed-loop connection with the backpack 200. The backpack connection device 100 includes a seat body 110, a locking body 120, a pressing body 130, and a force-applying assembly 140. The seat body 110 is fixedly connected to the frame 212. The fixed connection method between the seat body 110 and the frame 212 is not limited. For example, the seat body 110 and the frame 212 can be detachably fixedly connected by a fastening assembly, or can be fixedly connected in an integral form. In this embodiment, the seat body 110 and the frame 212 are integrally formed. This setting method is more stable and reliable, but those skilled in the art can understand that if a detachable connection method is adopted, the seat body 110 can also be set independently.

[0038] See also Figure 7The seat body 110 is provided with a channel 111 for the backpack strap 200 to pass through. As long as the adjustment belt 220 can be allowed to pass through, the shape and structure of the channel 111 can be in various forms, such as directly opening a through groove, etc. In the present embodiment, the channel 111 is surrounded by a first block 1111, a second block 1112, and a third block 1113, wherein the first block 1111 and the second block 1112 are arranged on one side of the channel 111, and the third block 1113 is arranged on the other side of the channel 111 and on the opposite side of the gap between the first block 1111 and the second block 1112. This structure can reduce the weight of the backpack strap connection device 100 on the one hand, and is also beneficial to reduce the wear of the adjustment belt 220 on the other hand.

[0039] See also Figure 3 and Figure 7 The locking body 120 is mounted on the seat 110 and rotates within a set angle range, and the pressing body 130 is mounted on the locking body 120. The structure and shape of the seat 110 in the present invention may not be limited, for example, it may be circular, rectangular or irregular; the rotatable mounting form of the locking body 120 on the seat 110 may also be various, for example, corresponding mounting holes may be provided on both the seat 110 and the locking body 120, and the two may be hinged by a rotating shaft; or a boss rotating shaft may be directly provided on the seat 110, and a mounting hole may be provided only on the locking body 120, so that the mounting hole on the locking body 120 is clamped on the boss rotating shaft on the seat 110; or a boss rotating shaft may be directly provided on the locking body 120, and a mounting hole may be provided on the seat 110 so that the mounting hole on the seat 110 is clamped on the boss rotating shaft of the locking body 120. In this embodiment, a locking body mounting seat 113 is provided on the seat 110, a rotating shaft hole (not numbered) is provided on the locking body mounting seat 113, and ribs 122 are provided on both sides of the locking body 120, and the ribs 122 on both sides are respectively clamped on the outer sides of the two ends of the locking body mounting seat 113, and through holes 1221 corresponding to the rotating shaft holes are provided on the ribs on both sides, and the first rotating shaft 101 is inserted into the through hole 1221 and the rotating shaft hole to realize the hinge connection between the locking body 120 and the seat 110. The locking body 120 is rotatably mounted on the first rotating shaft 101, and rotates within a set angle range under the obstruction of the seat 110.

[0040] See also Figure 3 and Figure 7The force-applying assembly 140 is installed between the seat body 110 and the locking body 120, and is used to apply a force to the locking body 120, so that the pressing body 130 presses and fixes the backpack belt 200 on the seat body 110. The installation method of the force-applying assembly 140 between the seat body 110 and the locking body 120 is not limited, and can be any suitable method, such as fixed connection, movable connection, etc. The type of force applied by the force-applying assembly 140 can be tension or pressure. Considering the rotatable installation relationship of the locking body 120 on the seat body 110 and the installation of the force-applying assembly 140, when the force of the force-applying assembly 140 is pressure, the force-applying assembly 140 and the pressing body 130 are respectively arranged on both sides of the first rotating shaft 101, so that when the pressure of the force-applying assembly 140 acts on the side of the locking body 120 away from the pressing body 130, the pressing body 130 squeezes the backpack belt 200, thereby pressing and fixing the backpack belt 200 on the seat body 110. When the applied force is a tensile force, the force-applying component 140 and the clamping body 130 are arranged on the same side of the first rotating shaft 101, so that when the tensile force of the force-applying component 140 acts on the locking body 120, the clamping body 130 can also squeeze the backpack strap 200, thereby pressing and fixing the backpack strap 200 on the seat body 110.

[0041] See also Figure 6 Considering that the seat body 110 and the frame 212 in the present invention are an integrated structure and are not convenient for replacement, in order to increase the strength of the locking body mounting seat 113, in one embodiment of the present invention, a reinforcing rib 115 is also provided on the locking body mounting seat 113. The reinforcing rib 115 can enhance the strength of the locking body mounting seat 113 to prevent the locking body mounting seat 113 from being damaged due to insufficient strength, thereby causing the entire frame 212 to be scrapped.

[0042] See also Figure 7 Considering that it is impossible to bear a large load only by relying on friction, in an example of the backpack connection device 100 of the present invention, a load-bearing body 112 is provided on the seat body 110 on one side of the channel 111, and the adjustment belt 220 of the backpack 200 enters from the channel 111 on one side of the load-bearing body 112, and extends along the upper surface of the load-bearing body 112 to the other side of the load-bearing body 112 and passes out, and the pressing body 130 presses the adjustment belt 220 on the load-bearing body 112. The load-bearing body 112 can bear the load on one hand, and on the other hand, it converts the direction of the friction force into a direction different from the load direction, which can increase the connection stability of the backpack connection device 100.

[0043] See also Figure 7 In the present invention, as long as the effective compression of the backpack 200 can be achieved, the structure and installation method of the compression body 130 are not limited. In order to reduce the friction resistance during the adjustment process, in an example of the backpack connection device 100 of the present invention, the compression body 130 is cylindrical and is rotatably mounted on the locking body 120.

[0044] See also Figure 7 In an example of the backpack connection device 100 of the present invention, a first friction-increasing structure (not marked) for increasing the compression friction force is provided on the compression body 130. The first friction-increasing structure can be any suitable structural form that can increase the friction force between the compression body 130 and the backpack 200, for example, a plurality of dot-shaped protrusions or a plurality of wavy patterns are provided on the outer cylindrical surface of the compression body 130. In this embodiment, the first friction-increasing structure includes a plurality of first teeth 133, and the plurality of first teeth 133 are evenly distributed on the compression body 130 along the circumferential direction to form a straight gear-like structure, which can reduce the relative sliding between the compression body 130 and the surface of the compression body 130.

[0045] See also Figure 7 In an embodiment of the backpack connection device 100 of the present invention, the load-bearing body 112 is a cylindrical structure, and a second friction-increasing structure (not shown) for increasing the friction of the backpack 200 is provided on the load-bearing body 112. The second friction-increasing structure can be any suitable structural form that can increase the friction between the load-bearing body 112 and the backpack 200, for example, a plurality of dot-shaped protrusions or a plurality of wavy patterns are provided on the outer cylindrical surface of the load-bearing body 112. In this embodiment, the second friction-increasing structure includes a plurality of second teeth (not shown), which extend along the axial direction of the load-bearing body 112 and are evenly distributed on the pressing body 130 along the circumferential direction of the load-bearing body 112, thereby forming a straight gear-like structure, and the plurality of second teeth are matched and engaged with the plurality of first teeth 133 across the backpack 200, so that the relative sliding of the backpack 200 between the load-bearing body 112 and the pressing body 130 can be reduced.

[0046] In the present invention, as long as the carrying belt 200 can be pressed against the load-bearing body 112 by the pressing body 130, the positional relationship between the pressing body 130 and the load-bearing body 112 can be various. Figure 7 In one embodiment of the backpack connection device 100 of the present invention, the pressing body 130 is disposed above one side of the load-bearing body 112. Figure 8 In another embodiment of the present invention, the compression body 130 is disposed below the side of the load-bearing body 112 away from the channel 111. This structure can increase the contact area between the shoulder strap 200 and the load-bearing body 112, thereby preventing the shoulder strap 200 from sliding relative to the load-bearing body 112 due to vibration.

[0047] See also Fig. 9The backpack connection device 100 of the present invention may also include more clamping bodies 130. In one embodiment of the backpack connection device 100 of the present invention, the backpack connection device 100 includes two clamping bodies 130, which are marked as a first clamping body 131 and a second clamping body 132 respectively; the first clamping body 131 is rotatably mounted on the locking body 120 via the second rotating shaft 102, and the second clamping body 132 is mounted on the locking body 120 via the third rotating shaft 103, so that a concave gap is formed between the first clamping body 131 and the second clamping body 132. When the locking body 120 is in a normal state (i.e., there is no external force interfering with the entire backpack connection device 100, and the clamping body clamps the backpack), the load-bearing body 112 is inserted into the gap between the first clamping body 131 and the second clamping body 132. During the process of adjusting the length of the adjusting belt 220, the adjusting belt 220 is pulled to slide along the surface of the load-bearing body 112, and the adjusting belt 220 drives the first clamping body 131 and the second clamping body 132 to rotate under the action of friction. During the rotation of the first clamping body 131 and the second clamping body 132, the first clamping body 131 and the second clamping body 132 are pressed toward the load-bearing body 112 under the action of the force-applying assembly 140, and the automatic alignment of the position of the load-bearing body 112 is achieved through the rotation of the first clamping body 131 and the second clamping body 132.

[0048] See also Figure 7 In the backpack connection device 100 of the present invention, the structure of the force-applying component 140 can be various.
