Abstract

The utility model relates to a bicycle cushion which can be turned up and down freely. A screw (3) is fastened at a round steel tube (1) at the middle of the cushion; when a nut (4) is relaxed, the screw (3) can pull forwards and backwards and turn left and right inside an inner hole of an axle sleeve (5) to turn the cushion; when the nut (4) is tightened, a bolt at the round steel tube (1) of the cushion is inserted into a groove at the axle sleeve (5), the screw can not turn left and right and can not move forwards and backwards, which ensures that the cushion is fastened at a bicycle frame and is convenient for a rider to control the balance. The cushion can be turned freely, which can conquer the disadvantages of being sunned or being wetted by rain.

Description

Turn-over bike saddle

Affiliated technical field

The utility model relates to a kind of arbitrarily saddle of turn-over.

Background technology

Known a few days ago saddle is a mounting spring below the cot, be fixed on the vehicle frame by the inclined tube under the support, it is fixed, goes out sometimes car is parked on the road limit, summer, the sun one shone the surface that becomes " burning hot ", and the people rides and can feel the degree that can not bear; After raining, cushion surface drenches also inconvenience to be used.

Summary of the invention

In order to overcome the shortcoming in the existing above-mentioned use of saddle, the utility model provides a kind of arbitrarily saddle of turn-over, upper surface has sunburn, lower surface since backlight can " not burning hot ", just solved cushion " burning hot " after the upset of top and bottom and the problem of drenching.

The technical scheme that its technical matters that solves the utility model adopts is: design top and bottom the same (promptly two-sided) cushion, the centre is supported with a thick round steel pipe, collar extension has two square " latches " after the round steel pipe, when nut screws, " latch " just puts in the groove of fixed hub, and cushion just can left-right rotation, move forward and backward; After nut unscrewed, round steel pipe just can be pulled out freely and be overturn, and when nut being screwed behind the turn-over, the cushion behind the turn-over is fastened on the axle sleeve again and is unable to stir any more again, and allows the cyclist can grasp the state of equilibrium of bicycle.

The beneficial effects of the utility model are, can pull out the cushion top and bottom of freely overturning, and have overcome the defective that is sunburn and be moistened by rain by sunlight.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is an integral structure of the present utility model.

Fig. 2 is round steel pipe and cushion shape sheetmetal.

Fig. 3 (a), Fig. 3 (b) are that nut and screw are faced, right elevation.

Fig. 4 (a), Fig. 4 (b) are that axle sleeve is faced, right elevation.

Among the figure 1, round steel pipe, 2, cushion shape sheetmetal, 3, screw, 4, nut, 5, axle sleeve, 6, bend pipe, 7, foam-rubber cushion and exoperidium thereof.

The specific embodiment

In Fig. 1,2/3 of round steel pipe (1) length is middle slit to cuing open, and cushion shape sheetmetal (2) embeds wherein, fixes with fastening primary screw; Round steel pipe (1) is not cut an end open negative thread, and screw (3) screws in wherein, and fixes with primary screw; Screw (3) can slide front and back in axle sleeve (5) endoporus; The rotation of nut (4) can screw or unscrew screw (3).Foam-rubber cushion and exoperidium thereof (7) play a part the buffering and saddle horse comfortable.

In embodiment illustrated in fig. 2, cushion shape sheetmetal (2) (thick 3mm) embeds round steel pipe (1) centre joint and fixes with primary screw; Round steel pipe (1) other end has negative thread, and there are two small embossments " latch " on a mouthful limit.

In the embodiment shown in fig. 3, nut (4) can be gone up rotation at screw (3), adjusts its position on screw (3).When nut (4) when screwing, check screw (3) before and after plaing a part.

In the embodiment shown in fig. 4, axle sleeve (5) is three links in appearance, its lower end links to each other with bend pipe (6) with screw thread, on the pipe limit, left aperture two grooves are arranged on it, " latch " on the round steel pipe (1) just can insert wherein, when nut (4) when screwing, play left and right sides check screw (3); It is smooth inner wall that axle sleeve (5) is gone up pipe orifice, and nut (4) is when unscrewing, and screw (3) can slide before and after axle sleeve (5) is gone up in the pipe orifice, allows " latch " to leave groove, cushion turn-over just free to rotate.
