Detailed description of the invention
Detailed description of the invention of the present utility model is, as shown in the figure:
Embodiment 1, a kind of nice and cool backpack devices, comprise an a knapsack A and backrest device B, wherein, knapsack A has a back part A1, backrest device B comprises a pair cross bar 1 and a pair straight-bar 2, and described cross bar 1 correspondence is fixedly arranged on the upper and lower of back part A1 respectively, and described straight-bar 2 correspondence is arranged in the left and right side of described cross bar 1 respectively; And described straight-bar 2 is respectively equipped with at least one back-up block 3 outwardly, has two back-up blocks 3 in the present embodiment, two back-up blocks 3 on each straight-bar 2 all can be lowered on described straight-bar 2 and move and locate; Described straight-bar 2 all can be adjusted along described cross bar about 1 and moves and locate again.
As Fig. 2, shown in Fig. 3, described straight-bar 2 has profile groove 21 always, and back-up block 3 comprises cushion 31, support seat 32, first bolt 33 and the first nut 34, wherein, cushion 31 is combined in the outside of support seat 32, first bolt 33 is fed through straight profile groove 21 from the inner side of straight profile groove 21, and the first nut 34 is located and backwardly outer is had convex section 331, supportting on seat 32 by convex section 331 spiro again, and regulate the distance of support seat 32 spiro on convex section 331 with regard to the salient position of adjustable support block 3, and adjust when moving back-up block 3 position, first nut 34 of loosening makes its back-up block 3 can lower on straight profile groove 21 to move, after again screwing tight the first nut 34, then back-up block 3 can be fixed position again.Described cross bar 1 has a cross-sectional ditch 11, cross-sectional ditch 11 has multiple location indentations 12, multiple location indentations 12 can be wavy, and the upper and lower end of straight-bar 2 is respectively arranged on the cross bar 1 of upper and lower by bolt group 4, and bolt group 4 comprises the second bolt 41, elastic parts 42 and the second nut 43; Wherein, elastic parts 42 is sheathed on the second bolt 41, and the second bolt 41 through cross-sectional ditch 11 with straight-bar 2 spiro on the second nut 43, in addition, cross bar 1 has a horizontal room 13, horizontal room 13 has one to wall 14 of pulling, and the second bolt 41 respectively has a spiral shell head 411, and spiral shell head 411 and elastic parts 42 are contained in the inside of horizontal room 13.
When tune moves the position of straight-bar 2, outer stretching bar 2 and cause elastic parts 42 by compression time, now, spiral shell head 411 moves away to wall 14 of pulling, cause straight-bar 2 can adjust and move in left and right along cross bar 1, and make the second bolt 41 be moved to different location indentations 12 by tune, and loose one's grip when decontroling straight-bar 2 and make elastic parts 41 return, made by the resilient force of elastic parts 41 its spiral shell head 411 push against in pulling wall 14 and locating again, and straight-bar 2 is located again.
