[0016] In order to make the above features and advantages of the present invention more obvious and understandable, embodiments are given below with reference to the accompanying drawings for detailed description as follows.
[0017] like Figures 1 to 4 As shown, a convenient quick-release backpack includes a backpack body 1, a mounting base 2 is installed on the backpack body 1, a traction member 3 is rotatably installed on the mounting base 2, a main pull rope 4 is fixed to the top of the traction member 3, one end of the main pull rope 4 is installed on the top of the outer side surface of the traction member 3, a plurality of branch pull ropes 10 are arranged on the inner end surface of the traction member 3, a clamping head 13 for fixing the branch pull ropes 10 is arranged on the top of the inner side surface of the traction member 3, the branch pull ropes 10 and the clamping head 13 can be fixedly installed by binding or other existing fixing methods, one end of the plurality of branch pull ropes 10 is fixed on the traction member 3, and the other ends of the plurality of branch pull ropes 10 are respectively connected to respective quick-release connectors.
[0018] The quick-release connector includes a waist belt quick-release connector and a spring shackle 11, the spring shackle 11 includes a shackle body 16, a spring insertion rod 17 and a hook 18, one end of the hook 18 is connected to the shackle body 16 through a rotating shaft, the other end of the hook 18 is installed together with one end of the spring insertion rod 17 through a socket, and the other end of the spring insertion rod 17 is connected to the pull rope 10.
[0019] The spring shackle is provided with two hanging ears, each of which is provided with a hanging ring. One of the hanging ears is a fixed closed-loop hanging ear, and the other hanging ear is provided with a hook 18. The pulling of the pull rope can pull the spring plug rod 17 on the spring shackle, so that the hook 18 is separated from the spring plug rod, thereby making the hanging ear in an open state. The two hanging rings are respectively connected to the back frame and the shoulder strap through the webbing, so when the hanging ear is released, the shoulder strap and the back frame will be separated.
[0020] The waist belt quick-release connector includes a seat plate 12 and an external interface plate, the seat plate 12 is installed on the back frame, and the interface plate is installed on the waist belt. Plastic buckle assemblies are respectively provided at both ends of the waist belt. Two hinged splints are provided on the seat plate 12, and the tops of the two splints are respectively connected to a draw rope, and the two draw ropes are closed to one of the branch draw ropes 10. A clamping groove is formed between the two splints, and an interface column extending into the clamping groove is provided on the interface plate.
[0021] In this embodiment, the mounting seat 2 is symmetrically provided with support frames 6 on both sides of the traction member 3, a rotating shaft is passed through the bottom of the traction member 3, and the two ends of the rotating shaft are rotatably mounted on the two support frames 6, and a torsion spring is sleeved on the rotating shaft. When the main pull rope 4 is pulled, the top of the traction member 3 swings downward, thereby pulling the branch pull rope 10.
[0022] In this embodiment, a rope tube 5 is sleeved on the surface of the plurality of pull ropes 10, and the pull ropes 10 are movably inserted in the rope tube 5. A plurality of limit blocks 9 for fixing the rope tube 5 are installed on the back frame body 1. The use of the rope tube 5 can prevent the pulling of the pull rope 10 from being interfered by the outside, and ensure the stability of one-touch pulling when the back frame is quickly taken off.
[0023] In this embodiment, a clamping block 7 for fixing the rope tube 5 is detachably mounted on the mounting seat 2 , and a through hole for the rope tube to pass through is formed on the clamping block 7 , and each rope tube 5 corresponds to one through hole.
[0024] In this embodiment, a plurality of hollow grooves 8 are provided on the backpack body 1, which effectively reduces weight and can be used for ventilation, and can also provide auxiliary fixing for the combination of the backpack and the backpack, such as the webbing on the backpack can be fixed through the hollow grooves.
[0025] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any simple modification, equalization change and modification made to the above embodiment by any technician familiar with the field without departing from the content of the technical solution of the present invention based on the technical essence of the present invention shall fall within the scope of the present invention.
