DETAILED DESCRIPTION

[0028] See attached Figure 1-12 An embodiment of the utility model discloses a quick-release connection structure for a helmet, comprising a front hook 1, a connecting seat 2, a first connecting belt 3, a quick-release assembly 4, a second connecting belt 5 and a rear hook 6, wherein the front hook 1 is fixed at the middle position of the front end of the helmet, the rear hook 6 is fixed at the middle position of the rear end of the helmet, the bottom of the connecting seat 2 is snap-connected with the front hook 1, and the top of the connecting seat 2 is connected to one end of the first connecting belt 3; the quick-release assembly 4 has length adjustment, unlocking and locking functions, the other end of the first connecting belt 3 is fixed to one end of the quick-release assembly 4; the other end of the quick-release assembly 4 is sequentially connected to the second connecting belt 5 and the rear hook 6.

[0029] The quick-release assembly includes a length adjustment button 10, a locking rack 11 and an unlocking wrench 12. The length adjustment button 10 is connected to the other end of the first connecting belt 3 through a fastener 13, and a locking rack 11 is inserted into the length adjustment button 10. The locking rack 11 is connected to the unlocking wrench 12, and the bottom of the unlocking wrench 12 is connected to one end of the second connecting belt 5 through a fastener 13.

[0030] A Velcro 9 is provided on the surface of the first connecting belt 3 , and after one end of the first connecting belt 3 passes through the weight-reducing groove 8 of the connecting seat 2 , it is connected to the connecting seat 2 through the Velcro 9 .

[0031] The other end of the second connecting belt 5 passes through the weight-reducing groove 8 of the rear end hook and is connected to the rear end hook 6 through a fastener 13 .

[0032] The length adjustment button 10 includes a button fixing seat 15, the bottom of which is connected to the first connecting belt 3 via a fastener 13, a pressure plate 14 is hinged on the inner side of the button fixing seat 15, and a torsion spring is provided at the hinge to facilitate the timely reset of the pressure plate 14 after being pressed; during operation, the locking rack 11 is released by pressing the pressure plate 14, thereby meeting the length adjustment requirements.

[0033] The unlocking wrench 12 includes a wrench fixing seat 20, the bottom of which is connected to the second connecting belt 5 via a fastener 13, a wrench 19 is hinged on the inner side of the wrench fixing seat 20, a rack clamping block 17 is hinged on the inner side of the wrench 19 via a rotating shaft 18, and the rack clamping block 17 is connected to one end of the locking rack 11.

[0034] The front hook 1 and the rear hook 6 are both made of ultra-high strength aluminum alloy and have weight-reducing grooves, so they are light in weight. A block is also installed at the head of the front hook 6 to ensure the reliability of the connection with the helmet.

[0035] The first connecting strap in the embodiment of the utility model is 15mm, one end of which is fixedly connected to the quick-release component 4 by a fastener 13, and the other end is provided with a Velcro 9, which is pasted and fixed after passing through the connecting seat 2; when adapted to helmets of different sizes, the length of the quick-release component can be quickly adjusted by adjusting the pasting position of the Velcro 9; the second connection is 20mm, and both ends are respectively connected and fixed to the quick-release component 4 and the rear end hook 6 by fasteners 13, the Velcro 9 and the fasteners 13 make the connection position of the first connecting strap and the second connecting strap firm and reliable, and the material of the connecting strap is a nylon material with high strength and excellent wear resistance. When the quick-release connection structure is not in use, it can be sorted and folded for storage, and the volume occupied is small.

[0036] See also Figure 8-10 When adapting to helmets of different sizes, the length of the quick-release assembly can be fine-tuned by adjusting the tooth position of the locking rack when locking; Fig.10 In a, when the length adjustment button is not pressed, the locking rack is pushed to the left, and the inclined surface of the locking rack 11 lifts the front end of the adjustment button. At this time, the stop surface 16 on the length adjustment button does not work; Fig.10 In b, when the length adjustment button is pressed, it passes through several teeth as needed. Due to the action of the torsion spring inside the adjustment button, the button is reset, and the front end of the button falls into the bottom of the locking rack teeth again. At this time, the length of the connecting belt is reduced, and the quick-release connection structure can be locked to the helmet with the unlocking wrench 12; when the locking rack 11 is pulled to the right, the length adjustment button stop surface 16 works, and the rack does not move. While pressing the length adjustment button downward, the locking rack can be pulled to the right. At this time, the button stop surface does not work. After releasing the button, the length adjustment button is reset under the action of the torsion spring.

[0037] See also Figure 11-12 The unlocking wrench 12 is fixed to the wrench fixing seat 20 by a fastener 13, and is fixedly connected to the locking rack 11 by a rack clamping block 17; when the unlocking wrench 12 is pulled up, the unlocking wrench 12 drives the locking rack 11 to move away from the helmet, thereby unlocking the quick-release connection structure locked on the helmet; when the unlocking wrench 12 is pressed down, the unlocking wrench 12 moves toward the helmet, and since the unlocking wrench 12 is connected to the locking rack 11 by the rack clamping block 17, the locking rack 11 is further driven to move toward the helmet, thereby locking the quick-release connection structure on the helmet. In addition, the distance L1 from the position where the finger presses the unlocking wrench to the rotating shaft is greater than the distance L2 from the hinge between the wrench and the wrench fixing seat to the rotating shaft, the lever arm is longer, and it is more labor-saving when pressing and locking.

[0038] When in use, the front hook is hooked in the middle of the front end of the helmet, and the rear hook is hooked in the middle of the rear end of the helmet. Press the unlocking wrench and push the locking rack forward until it can no longer be pushed. At this time, the quick-release connection structure is initially locked.

[0039] Pull up the unlocking wrench to loosen the quick-release connection group, press the length adjustment button, push the locking rack forward 1 to 2 teeth, and finally press the unlocking wrench hard to completely lock it.
