Detailed description of the invention
This rotary type knapsack is made up of backboard 1, upper box 2, lower box 3 and flap 4; Backboard 1 inner surface is symmetrically arranged with braces 5, and backboard 1 outer surface is fixed with upper box 2, and the backboard 1 below upper box 2 is equipped with flap 4 by rotating shaft 6 and torsion spring 7, and the termination of flap 4 is hinged with lower box 3.
Rotating shaft 6 is fixed with ratchet 8, the backboard 1 of ratchet 8 side is equipped with ratchet (not shown), ratchet and ratchet 8 are connected with a joggle, and the backboard 1 corresponding with ratchet is equipped with push rod 10 by spring 9, and push rod 10 is connected with detent contact.
Flap 4 and the corresponding surface of lower box 3 are provided with chute 11, by extension spring 18, slide block 12 is housed in chute 11, on slide block 12, connecting rod 13 is equipped with in activity, lower box 3 end face corresponding with chute 11 is provided with groove 15, groove 15 is built with connector 14, and one end of connecting rod 13 is flexibly connected with lower box 3 by connector 14.The effect of groove 15 is for connecting rod 13 provides an accommodation space, to make lower box 3 when non-opening and to keep fitting tightly between flap 4.
The flap 4 of chute 11 termination is provided with through hole, backboard 1 is fixed with pull rope 16, one end of pull rope 16 is fixedly connected with slide block 12 through through hole.The effect of pull rope 16 is in flap 4 expansion process, pull slide block 12 to make it move along chute 11 to the other end, thus is outwards pushed open by lower box 3 by the displacement of connecting rod 13, meanwhile, elongates extension spring 2 by slide block 12, makes its storage elasticity potential energy.
Lower box 3 is provided with movable buckle 17 with corresponding shape on backboard 1, is connected between lower box 3 with backboard 1 by movable buckle 17.
The upper box 2 of this rotary type knapsack and lower box 3 are two separate casings, can receive article respectively, compare traditional backpacks and have article feature easily of taking.During use, open movable buckle 17 and flap 4 can be made 6 to rotate around the shaft.In this process, because flap 4 is arranged on backboard 1 by rotating shaft 6 and torsion spring 7, the flap 4 around the shaft 6 process torsion springs 7 rotated can increase flap 4 rotary resistance, and the effect of ratchet 8 and ratchet is eliminate this resistance, in case spline plate 4 resilience under the using most of torsion spring 7.After article of taking complete, pressing push rod 10, makes push rod 10 promote ratchet and ratchet 8 departs from, and under torsion spring 7 and extension spring 18 act on, flap 4, lower box 3 close up closed to backboard 1, thus get back to original state.
The lower box 3 maximum rotation angle of this rotary type knapsack is 270 degree, can make user when not overall take off knapsack the article of taking in lower box 3, eliminate the step needing to take off knapsack before traditional backpacks takes article, greatly facilitate the use of user.Be particularly suitable for delivering goods to the customers and outdoor activity use of middle smallclothes courier packages.
