Abstract

A bicycle seat sleeve comprises a triangular outer layer. Three corners of the outer layer are respectively cut into inner unfilled corners; the inner unfilled corners are all turned down to the lower side of the outer layer; two side lines of each inner unfilled corners are respectively coincided into one line and fixedly connected into a whole, so that the outer layer is in a sack-like structure with an opening at the lower end; and an expansion device capable of adjusting the size of the opening is further arranged on the opening. The bicycle seat sleeve made of monoblock materials needs no complicated pre-cutting, and is a bicycle protecting device with convenient processing, low cost and reasonable structure. The bicycle seat sleeve is directly and tightly sleeved on a bicycle seat without site limitation and completely isolated from dust and rainwater. When a bicycle is rid, the bicycle seat sleeve can be taken down, folded into a bicycle seat sleeve in folded state and directly plugged to the lower side of the bicycle seat without occupying space.

Description

Bike saddle cover

Technical field

The utility model relates to a kind of bicycle fender guard, specifically is meant bike saddle cover.

Background technology

Because drive simple, convenient parking, cheap, so bicycle always is exactly the most widely used trackless terrestrial vehicle.People arbitrarily park bicycle usually and do not use any cope protection, cause bike saddle easily to be infected with dust and rainwater, have in advance bike saddle once be cleaned before driving once more.

For addressing this problem, normally directly get raincoat or canvas whole bicycle rack is hidden, but employed raincoat or canvas inconvenience are deposited need drive bicycle the time, and if also easily blown off in the bigger occasion of wind-force.Can also make guard shield for bike saddle specially, when parking, guard shield is enclosed within on the bike saddle gets final product, the side of occupation of land is not unexpected is yet blown off by wind, but triangle saddle type shape for the coupling bike saddle, have to adopt the material of many cuttings in advance to be sewed up, so tooling cost is than higher, moulding is also imperfect.

Therefore, demand a kind of bicycle fender guard easy to process, with low cost, rational in infrastructure urgently and remedy the deficiencies in the prior art.

The utility model content

The utility model has proposed a kind of bike saddle cover just for this purpose, do not need directly to adopt whole material to make through complicated cutting in advance, and also very easy to use.

For achieving the above object, the utility model has adopted following technical scheme:

Bike saddle cover, comprise a leg-of-mutton epidermis, three angles of this epidermis are cut into interior unfilled corner respectively, unfilled corner is turned over all down to the epidermis downside in each, and two sidelines of unfilled corner overlap respectively and are a line and are connected to one in each, make epidermis become the cystic structures that the lower end has an opening, also be provided with the retractor device of this openings of sizes of scalable on this opening.

Retractor device wherein is the flanging along the collapsible fastening of this edge of opening, can also be the bungee of sewing up along this edge of opening.

As improvement of the technical scheme, epidermis is the preferable fabric of elasticity or leather or plastic film or other film materials.

The utility model compared with prior art has following good effect:

Bike saddle cover of the present utility model adopts whole block material to make, do not need through complicated cutting in advance, and be a kind of bicycle fender guard easy to process, with low cost, rational in infrastructure; Bike saddle cover directly tightly is enclosed within on the bike saddle, not limited by the place, isolate dust and rainwater fully; Bike saddle cover can be taken off when driving bicycle, it is converted into the bike saddle cover of folded state, directly fill under the bike saddle, not take up space.

Fig. 2 is a structural representation of the present utility model.

Fig. 3 is a running condition reference diagram of the present utility model.

Shown in the figure:

The 1-bike saddle cover, unfilled corner in the 2-epidermis, 21-, 22-opening, 23-bungee, 3-bike saddle.

The specific embodiment

Below in conjunction with specification drawings and specific embodiments the utility model is further described.

As shown in Figure 1 and Figure 2, bike saddle cover 1, comprise a leg-of-mutton epidermis 2, this epidermis 2 is the preferable fabric of elasticity or leather or plastic film or other film materials, three angles of this epidermis 2 are cut into interior unfilled corner 21 respectively, unfilled corner 21 is turned over all down to epidermis 2 downsides in each, and two sidelines of unfilled corner 21 overlap respectively and are a line and are connected to one in each, make epidermis 2 become the cystic structures that the lower end has an opening 22, also be provided with the retractor device 23 of this openings of sizes of scalable on this opening 22, this retractor device 23 is bungees of sewing up along this edge of opening.

As shown in Figure 3, bike saddle cover 1 of the present utility model directly tightly can be enclosed within on the bike saddle 3, not limited by the place, isolate dust and rainwater fully; Bike saddle cover 1 can be taken off when driving bicycle, it is converted into the bike saddle cover 1 ' of folded state, directly fill in bike saddle 3 times, not take up space.

Claims
