Description

A kind of strainer

Technical field

The utility model is related to the devices that shoulder strap accessories field more particularly to a kind of shoulder strap are adjusted.

Background technology

Currently, portable pillar is usually set on retaining ring by strainer, during adjusting shoulder strap length, need to adjust simultaneously Section shoulder strap and strainer could move the position of strainer to change the length of shoulder strap.In actual use, traditional pine It is held in more bothersome when adjusting, it is more difficult to easily be operated by one hand.And traditional elastic buckle structure is not easy to give birth to Production processing, versatility are small.

Utility model content

To solve the above-mentioned problems, the utility model adopts the following technical scheme：

A kind of strainer, feature are made in：Including retaining ring, loose-back band, portable pillar and regulation ring, shoulder strap is across regulation ring point At contraction section and loosen section, the end set of contraction section has portable pillar, retaining ring to be fastened in portable pillar by loosening section.

Preferably, retaining ring is cyclic structure, and movable column length is more than the internal diameter of the retaining ring.

Preferably, portable pillar both ends are equipped with pillar, and pillar is equipped with limiting slot.

Preferably, structure is led to during portable pillar is, and is equipped with drawstring.

Preferably, regulation ring is fixed on knapsack.

Preferably, portable pillar is divided into the two parts mutually to socket-connect, and belled position is equipped with resistive rubber.

The utility model has the beneficial effects that：It can be by pulling drawstring to drive portable pillar to change position, to band The dynamic shoulder strap movement being connected on movable button, the problem of to reach the shoulder strap length for adjusting and needing.Pass through this design, user It only needs that by drawstring shoulder strap can be adjusted, it is time saving and energy saving, it is easy to operate.And this mode for separating portable pillar and retaining ring, It is more convenient the production and processing of this strainer.Strainer can be made to adapt to the back ofs the body of more width by the portable pillar of adjustable length Band only needs to change retaining ring during produce reality use and can be achieved with the use on different in width shoulder strap.

Description of the drawings

Fig. 1 is the mounting structure schematic diagram of the utility model,

The sectional view of the positions Fig. 2 the utility model portable pillar,

In figure：Retaining ring 1, the first inner ring 11, the second inner ring 12, shoulder strap 2, regulation ring 21 loosen section 22, and contraction section 23 is living Dynamic column 3, drawstring 31, pillar 32, limiting slot 33.

Specific implementation mode

The utility model is further detailed below in conjunction with the accompanying drawings：

Such as Fig. 1, portable pillar 3 is placed in 1 one side of retaining ring, and 1 inner ring of retaining ring is divided into the first inner ring 11 and the second inner ring 12. Portable pillar 3 is connected to one end of shoulder strap 2, and is provided at both ends with pillar 32 for preventing shoulder strap 2 from falling off portable pillar in portable pillar 3 3；The other end of shoulder strap 2 is first passed through from 1 inner ring of retaining ring, then passes through the regulation ring 21 being arranged on knapsack is indentured, shoulder strap 2 is divided At contraction section 23 and loosen section 22, one section between portable pillar 3 and regulation ring 21 is contraction section 23, is then worn from the first inner ring 11 Later portable pillar 3 is bypassed, is subsequently passed through from the second inner ring 12, one end that shoulder strap 2 is finally not connected with to portable pillar 3 is fixed on packet With.

Lead to structure in portable pillar 3 generally one, is equipped with drawstring 31.When needing to adjust, only it need to pull drawstring 31 can To realize regulatory function.

Such as Fig. 2,3 both ends of portable pillar are equipped with pillar 32, shoulder strap 2 around being located between two pillars 32 on the shaft of portable pillar 3, from And shoulder strap 2 by the pillar 32 at both ends without departing from portable pillar 3.Meanwhile limiting slot 33 is additionally provided on pillar 32,33 size of limiting slot Match with position and 1 ring body of retaining ring.Portable pillar 3 divides two parts to be mutually socketed, two sections of socket parts to be arranged with resistive rubber The frictional force between two sections is improved, with up to the purpose that can fix 3 length of portable pillar when needed.By pulling or squeezing at both ends Portable pillar 3 makes 3 thinner one end of portable pillar deeply or pulls out thicker one end, to realize the purpose for adjusting portable pillar length.

Since one end that regulation ring 21 and shoulder strap are not connected with portable pillar 3 is fixed.When pulling drawstring 31, retaining ring 1 is driven to exist It is moved on shoulder strap 2, to reconcile the length of backpack strip by adjusting the length of contraction section 23 between portable pillar 3 and regulation ring 21 It is short.

The above is the preferable embodiment of the utility model, therefore all according to described in the utility model patent application range The equivalent change or modification done of structure, feature and principle, be included in the scope of the utility model patent application.
