Abstract
The invention discloses a strap retractable bag. The strap retractable bag comprises a knapsack and a strap, wherein the knapsack is provided with a device for retracting the strap and a braking device; the retracting device of the knapsack is provided with a runner, a core shaft and a power spring; the braking device of the knapsack is provided with a tension spring shaft, a tension spring, a braking block and a fixing shaft; two outer covers need to be arranged on two surfaces of each of the retracting device and the braking device so that the retracting device and the braking device can be mounted in the outer covers; therefore, by the strap, the bag can be carried on back or held with a hand; and the invention aims at providing the strap retractable bag which is simple in structure, easy to machine and manufacture, convenient, practical and low in cost.
Description
Technical field
The invention relates to a kind of knapsack, more particularly, it is about a kind of braces telescopic package.
Background technology
Present satchel knapsack, the not flexibles of general band, flexible also can not stretch too much even if having, like this concerning not too suitable sometimes the people of individual sub-height, and when wrapping that the back of the body will be carried, long braces also will be held in addition, not too convenient, sometimes also can make dirty and maybe can tangle some object, can mention so far, what also do not have strap retractable can carry on the back the bag also can carried.
Summary of the invention
The present invention overcomes the deficiencies in the prior art, provides a kind of braces telescopic package.
The object of the invention is to be achieved by following proposal;
Braces telescopic package of the present invention, it comprises knapsack, braces, and described knapsack is provided with the device of device and the braking that braces can be made to bounce back, and the restoring device of knapsack is provided with runner, mandrel, clockwork spring; The brake apparatus of described knapsack is provided with tension spring shaft, extension spring, brake block, fixed axis; The two sides of retraction and brake apparatus is preferably also provided with two outer covers, retraction and brake apparatus to be installed on its inside.
Advantage of the present invention is:
1, structure simple, be easy to make;
2, easy to use, with low cost.
Accompanying drawing explanation
Fig. 1 is embodiments of the invention overall schematic;
Fig. 2 is the apparatus structure schematic diagram making braces flexible of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail:
In Fig. 1,2, braces telescopic package of the present invention, it comprises knapsack A, braces B, knapsack A is provided with the device C that braces can be made to bounce back and brake, the two sides of retraction and brake apparatus C is preferably also provided with two outer cover M, so that it is inner retraction and brake apparatus C to be installed on it, outer cover M is also provided with installing hole, can rivet like this with knapsack A; The restoring device of knapsack A is provided with runner D, mandrel E, clockwork spring F, and mandrel E is fixed in outer cover M, and runner D center is installed on mandrel E, clockwork spring F one end is fixed on mandrel E, one end is fixed on runner D, and braces B is coiled on runner D, and runner D outer rim is gear shape; The brake apparatus of knapsack A is provided with tension spring shaft G, extension spring H, brake block I, fixed axis J, fixed axis J is fixed in outer cover M, brake block I is installed on fixed axis J, but can rotate centered by fixed axis J, extension spring H one end draws motion block I one end and is fixed on tension spring shaft G, and brake block I one end is the shape that can engage with runner D; When braces B will be elongated, one end (outside outer cover M) of brake block I upwards pushes away by available hand, the other end of such brake block I is separated with runner D, has not namely braked, and the braces B be coiled on runner D can be pulled out with when pulling, can take-off the brake block I when moving suitable length to, effect due to extension spring H makes one end of brake block I pull to runner D, and now brake block I and runner D closes up, and namely engagement has been braked, runner D cannot be rotated, reach the object of braking braces B; If allow braces B bounce back, also with hand, brake block I one end upwards can be pushed away toward (outside outer cover M), but do not pull braces B, because clockwork spring F has gathered energy when braces B is drawn out, so make runner D turn round, also just make braces B bounce back, this design principle and ordinary tape measure are the same.
