Abstract

The utility model relates to a device for rotating and locking a handlebar tube of a folding bicycle, and the device comprises a handlebar tube locking head, a locking head bolt, a nut, a joint bolt, a compression spring, a rotary shaft sleeve, a groove-shaped pad and other main parts. The device is characterized in that as the handlebar tube is jointed with the handlebar tube locking head, a rotary shaft which is matched with the shaft sleeve is arranged below the handlebar tube locking head; a linear boss is prefabricated at the lower end of the rotary shaft; the boss can be embedded in the cross-shaped groove-shaped pad which is matched therewith; when the joint bolt is screwed, the handlebar tube and a handlebar vertical tube are locked to a whole body; when the bolt is released, the handlebar tube and the handlebar vertical tube are loosened, and then the handlebar tube can be lifted by a certain height and rotate by 90 degrees in reverse direction, thereby leading the handlebar tube to be parallel to the axial direction of the folding bicycle and further greatly reducing the size of the overall bicycle after being folded.

Description

Be used for folding bicycle the device of transverse tube rotation and locking

1. technical field:

The utility model relates to a kind of folding bicycle annex, particularly relates to a kind of folding bicycle that is used for transverse tube rotation and latching device.

2. background technology:

The utility model is granted multifunctional folding bicycle (ZL 0225 3380.X) parts of patent and the improvement of part in person.

Intrinsic folding bicycle transverse tube is revolved turn 90 degrees, be that bearing pin and spring in the wearing or featuring stage armour standpipe finished, but in use find because the pitch-row of bearing pin insertion S. A. is shorter, cause handlebar to shamble, inserting for a long time influences the rotation of transverse tube and S. A. again, and main is to can't resolve the drawback that handlebar rocks.

3. summary of the invention:

The purpose of this utility model is to provide a kind of and promptly solves the rotation problem of transverse tube, solve again simultaneously transverse tube and handle riser owing to be connected not firm occur rock unstable problem, thereby on technical measures, reached the beneficial effect of collection function and safety and one.

The utility model includes on it: the transverse tube locking head, and locking head bolt, nut, manually fastening bolt nut, compression spring, rotary sleeve, cross groove pad, gland, manual bolt handle S. A., transverse tube, manual fastening bolt, S. A. bottom yi word pattern boss.Its structural relation is: transverse tube by the transverse tube locking head, the locking head screw bolt and nut is locked securely and is one, stepped hole is arranged in the S. A., the built-in compression spring in hole, manual fastening bolt and nut, at the prefabricated yi word pattern boss of the low side of S. A., install a cross groove pad in the bottom of axle sleeve, a gland is established in centre at cross groove pad and manual bolt handle, above-mentioned S. A. and axle sleeve are running-fits, the yi word pattern boss and the groove on the cross bath pad of S. A. bottom also are running-fits, both can embed the location, the lifting of also can offing normal, with reach can left rotation and right rotation transverse tube purpose.

Four. description of drawings:

Fig. 1 is that the utility model integral structure cuts open scheme drawing

Fig. 2 is the part sectional view of the utility model S. A. (10) bottom

Fig. 3 is the partial cutaway right side view (left side is as the same) of the utility model S. A. (10).

Fig. 4 is the bottom upward view of S. A. (10)

Fig. 5 is that the front view, 7 ' of cross bath pad (7) is a groove.

Fig. 6 is that the birds-eye view, 7 ' of cross bath pad (7) is a groove.

Five. the specific embodiment:

Below in conjunction with accompanying drawing the utility model is described in further detail:

1 the transverse tube locking head among Fig. 1,2 locking head bolts, 3 nuts, 4 manual attachment bolt nuts, 5 compression springs, 6 rotary sleeves, 7 cross bath pads, 8 glands, 9 manual bolt handles, 10 S. A.s 11 are transverse tube, 12 manual fastening bolts, 13 S. A.s bottom yi word pattern boss.

Among Fig. 1 transverse tube (11) by transverse tube locking head (1), locking head bolt (2) and nut (3) locking, and transverse tube locking head (1) and S. A. (10) solder together, so also just and then rotation of S. A. (10) when transverse tube (11) is rotated, S. A. has a stepped hole in (10), the built-in compression spring in hole (5) and manual fastening bolt (12) and fastening bolt nut (4), armrest moves fastening bolt (12) S. A. (10) cross bath pad (7) and gland (8) is connected, S. A. (10) is a running-fit with axle sleeve (6), so S. A. (10) can about, about movable, because the bottom of S. A. (10) is shaped on in-line boss (13) in advance, but in the cross recess (7`) on this boss embedded groove pad (7), this cross recess can play positioning action, behind the handle that screws manual attachment bolt (12) (9), S. A. (10) is subjected to the counter pressure of nut (4) and is compacted, thereby make transverse tube is in firm state and unlikely left-right rotation again, when needs will revolve transverse tube (11) when turning 90 degrees, the handle (9) of manual attachment bolt (12) can be unscrewed, this moment S. A. (10) release of pressure, turn 90 degrees so just can mention S. A. (10) and revolve, the boss of its lower end is embedded in another groove in the cross recess pad, no matter so transverse tube (11) is just turn 90 degrees, or counter turning 90 degrees can be located because of boss and cross recessed cooperate.When transverse tube (11) is needed rotation, as long as the handle (9) of manual fastening bolt (12) is loosening, the rotation that just can freely link of transverse tube (11) and S. A. (10).Also just can make transverse tube and folded bicycle axially both can be vertical also can be parallel, promptly reach in this way and make folded bicycle receive the minimized purpose of its volume of poststack.
