Specific embodiment

As shown, setting

Bowl 10 on one, generally at tubulose, bowl 10 has two opposite ends on this, and wherein one end of bowl 10 has one first on this Fixed part 11, in the present embodiment, first fixed part 11 have a plurality of clamping tooths of outside wall surface projection of bowl 10 from this 111, respectively between the clamping tooth 111 at fixed distance；

One fixing piece 20, has one second fixed part 21 and a fixed perforation 22, second fixed part 21 and this is first solid Determine portion 11 to be fixedly connected, and the fixing piece 20 has the clamping slot 23 towards the fixation perforation 22, and the fixing piece 20 has court One external screw thread 24 of the reversed fixation perforation 22, in the present embodiment, which, which has towards one of bowl 10 on this, fixes Face 25, second fixed part 21 are set on the stationary plane 25, and second fixed part 21 has a plurality of recessed fixing grooves 211, respectively apart there is a fixed range between the fixing groove 211, makes have one fixed convex 212 between every two fixing grooves 211, Respectively the fixing groove 211 is provided with that respectively 111 blocking of clamping tooth of first fixed part 11 is allowed to fix, and respectively the clamping tooth 111 is by each The fixation of the fixation convex 212 makes on this bowl 10 will not be along circumferentially rotating；And the clamping slot 23 is a plum blossom in the present embodiment Hole；

One rotating member 30, has a rotation perforation 31, which has the internal screw thread towards the rotation perforation 31 32, which engages with the external screw thread 24, and in the present embodiment, which separately has the reversed rotation perforation 31 Plane of rotation 33, the plane of rotation 33 are equipped with a plurality of on-slip traces 331, which is provided with that user is allowed to rotate, and by this On-slip trace 331 allows user that can rotate the rotating member 30 more easily；

One clamping piece 40, has a blocking column 41 and a pushing and pressing part 42, which is provided with blocking and is incorporated into the blocking In slot 23, which is equipped with one first positioning region 421, and in the present embodiment, which is a plum blossom pillar, should Plum blossom pillar is provided with being equipped in the plum blossom hole, rotate bowl 10 on this can not；

One elastic component 50；

One skull 60 has one second positioning region 61, second positioning region 61 and 421 secure bond of the first positioning region, The elastic component 50 is set between the skull 60 and the clamping piece 40, and the elastic component 50 is by being butted on the clamping piece 40 and pushing against the head Lid 60.

Preferably, first positioning region 421 is a plurality of cylinders around the clamping piece 40, and second positioning region 61 is Around a plurality of circular grooves of the skull 60, it is equipped in the respectively circular groove respectively by the respectively cylinder, can rotate the clamping piece 40 not.

In the present embodiment, which is a undaform gasket, since undaform gasket has by being butted on the skull The one of 60 is high-end, and the low side by being butted on the pushing and pressing part 42, pushes against the clamping piece 40 by the elastic component 50, makes the clamping piece The 40 blocking column 41 can blocking be fixed in the clamping slot 23.

The structural configuration and its connection relationship that the above are the utility models in a preferred embodiment, the usage mode of the utility model is such as It is lower described:

The utility model has an a locking condition Q1 and pine oil state Q2；

Referring to Fig. 4, first positioning region 421 of the clamping piece 40 is equipped in when the utility model is when locking condition Q1 It in second positioning region 61, and then rotate the fixing piece 20 can not relative to second positioning region 61, bowl 10 is solid by this on this Determining part 20 can not rotate without can rotate；

When user needs to rotate bowl 10 on this, then user's hand holds the plane of rotation 33 of the rotating member 30, borrows The more frictional force of user's hand are provided by the on-slip trace 331 on the plane of rotation 33, allow user being capable of ease rotation this turn Moving part 30 cooperates when the rotating member 30 rotation by the internal screw thread 32 and the external screw thread 24, make first positioning region 421 by Gradually it is detached from the second positioning region 61；

After first positioning region 421 is detached from second positioning region 61, the utility model is converted to the pine from locking condition Q1 State Q2 is released, and then allows user that can rotate bowl 10 on this；

When user is intended to return back to locking condition Q1 from pine oil state Q2, then the rotating member 30, this turn are rotated further by Moving part 30 cooperates by the internal screw thread 32 and the external screw thread 24, and the rotating member 30 is made to move closer to the skull 60, keeps this first fixed Position portion 421 is mobile towards second positioning region 61, and then is equipped in first positioning region 421 in second positioning region 61, i.e., Return back to locking condition Q1.

Since user can directly adjust the rotating member 30, to select the utility model system to be located at locking condition Q1 or the pine State Q2 is released, when user is when riding bicycle, the utility model is able to use and converts to pine oil state Q2, when user stops Che Shi is then able to use the utility model and converts to locking condition Q1, and then solves bicycle in parking because headstock is easy to turn The problem of moving and toppling over.

The headstock of the utility model turns to locked instrument, can adjust rotating member, directly to select the headstock handle of bicycle Hand is in locking condition or pine oil state, and in pine oil state, bicycle, which can be turned to, rides, bicycle stop when, adjust to Locking condition prevents headstock from arbitrarily rotating and bicycle is caused to topple over.

Specific mentality of designing:

Headstock of the utility model system about bicycle, especially system turn to locked instrument about a kind of headstock, mainly to lock Headstock prevents headstock from rotating.

[1] headstock of general bicycle is to drive connection by by the front fork of handle and bicycle, and pass through a headset, Whereby when user is when converting handle, the front fork of bicycle can also be rotated, and allowed user that can control bicycle with this and turned To orientation.

[2] however, bicycle after a stoppage, headstock is easy to be collided because of others with passerby or process due to rotates its vehicle Head then be easy to cause bicycle to topple over when headstock is arbitrarily rotated.

[3] in view of this, it is necessory to solve bicycle because headstock can not lock, cause be easy to topple over when parking to ask Topic.

The purpose of the utility model is, solves bicycle because headstock can not lock, is easy the missing toppled in parking.
