Description

Scooter front tube compresses tightly cover

Technical Field

The invention relates to the field of scooters, in particular to a scooter front tube pressing sleeve.

Background

At present at the scooter mainly include sweep and locomotive, be equipped with the head tube on the locomotive, be equipped with the installation pipe on the sweep, and for the convenience of the transportation of scooter at present, the head tube on the locomotive and the installation pipe on the sweep are for dismantling the connection.

In the related art, a front pipe on a vehicle head is generally directly inserted or sleeved on a mounting pipe on a vehicle plate, then a control bolt penetrates out of the front pipe and the mounting pipe simultaneously, and a nut is screwed into a thread at one end, through which the bolt penetrates out, so that the front pipe is fixed on the mounting pipe.

To above-mentioned correlation technique, the inventor thinks, because the bolt exposes outside, influences the pleasing to the eye degree of scooter on the one hand, and on the other hand is in long-time outdoor use, and the easy corrosion of bolt to when dismouting head tube, comparatively hard.

SUMMERY OF THE UTILITY MODEL

Produce the corrosion for front tube and installation union coupling department, this application provides a scooter front tube and compresses tightly the cover.

The application provides a pair of scooter head tube compresses tightly cover adopts following technical scheme:

the utility model provides a scooter head tube compresses tightly cover, is including the body that is used for connecting the head tube, the body is used for cup jointing on the installation pipe, set up on the installation inside pipe wall be used for with body threaded connection's thread groove.

Through adopting above-mentioned technical scheme, during the use, cup joint the body on the installation pipe, then rotate the body, make body and installation pipe thread screw to can keep the stability of head tube to a certain extent, in addition because the body cup joints on the installation pipe, then can prevent to a certain extent that water and dust from entering into the thread groove, and then can reduce the possibility of installation pipe and the corrosion of body threaded connection position department, thereby it is comparatively convenient when the dismouting head tube.

Optionally, a locking block used for abutting against the installation pipe to limit the rotation of the pipe body is arranged in the pipe body.

Through adopting above-mentioned technical scheme, the setting of latch segment can pass through frictional force restriction body and rotate to can further strengthen the stability of head tube.

Optionally, the latch segment is used for following body axis direction slip setting is in the body, the latch segment cross-sectional area is followed body axis direction diminishes gradually, be equipped with on the body and be used for the drive the gliding driving piece of latch segment.

By adopting the technical scheme, when the pipe body is limited to rotate, the locking block is driven to move by the driving piece, and the cross section area of the locking block is gradually reduced along the axial direction of the pipe body, so that when the locking block is slid, the locking block can be extruded by the inner wall of the pipe body in the moving process, and the rotation of the pipe body is limited; this locking mode locks the body through the gliding mode of latch segment to because the gradual change of latch segment cross-sectional area, thereby can control the frictional force size between latch segment and the installation pipe, the operating personnel of being convenient for progressively applies force.

Optionally, the driving member includes a screw, the front tube is hinged to the tube body, and the front tube rotates to cover the screw.

By adopting the technical scheme, when the locking device is used, the locking block can be driven to slide by rotating the screw rod, and the screw rod can be covered by rotating the front pipe, so that the screw rod is prevented from being exposed, and the possibility of corrosion of the screw rod can be reduced; the driving piece is simple in structure and convenient to operate, the screw has a certain limiting function, and the locking block can be positioned at a proper position to a certain extent.

Optionally, the pipe body is internally provided with a stud which is connected with the thread groove in a threaded manner, the inner wall of the pipe body is fixedly connected with a step plate, and the stud is provided with a positioning plate which is used for abutting against the step plate.

Through adopting above-mentioned technical scheme, when the dismouting body, can rotate the double-screw bolt to the double-screw bolt can be screwed with the installation pipe screw thread, then need not to rotate body or installation pipe, thereby can avoid when rotating the body, because the existence of the latch segment in the body, can cause the influence to the rotation of body, and when rotating the installation pipe, the installation pipe can drive the sweep and rotate together, thereby is comparatively troublesome.

Optionally, an operation groove is formed in the positioning plate, and a tool is inserted into the operation groove to drive the stud to rotate.

Through adopting above-mentioned technical scheme, during the use, can rotate the locating plate through the instrument to be convenient for operating personnel operates.

Optionally, a gasket is arranged between the nut and the step plate.

Through adopting above-mentioned technical scheme, when rotating the screw rod, because the screw rod rotates and need drive to support tight piece and remove to when rotating the screw rod, need apply the effort in order to prevent the screw rod and support tight piece synchronous motion to the screw cap, thereby the setting of packing ring can prevent that the screw cap from causing wearing and tearing to the step board.

Optionally, the locking block is used for sleeving the mounting pipe, a plurality of convex blocks used for abutting against the inner wall of the pipe body are arranged on the outer wall of the locking block at intervals along the circumferential direction of the outer wall of the locking block, and the convex blocks are elastic.

By adopting the technical scheme, the plurality of convex blocks are arranged at intervals along the circumferential direction of the outer wall of the locking block, so that the stress stability of the locking block can be enhanced, meanwhile, the contact area between the locking block and the inner wall of the pipe body is increased, and the friction force between the inner wall of the pipe body and the locking block is improved; in addition, the bumps are arranged at intervals, so that the bumps are convenient to deform.

Optionally, the locking block is provided with a notch so that the locking block is in an open-loop arrangement.

Through adopting above-mentioned technical scheme, the latch segment of being convenient for warp, prevent the latch segment damage.

Optionally, the inner wall of the locking block is provided with anti-skid grains.

Through adopting above-mentioned technical scheme, increase the frictional force between latch segment and the installation pipe outer wall.

In summary, the present application includes at least one of the following beneficial technical effects:

1. when the mounting pipe is used, the pipe body is sleeved on the mounting pipe, then the pipe body is rotated, and the pipe body and the mounting pipe are screwed in a threaded manner, so that the stability of the front pipe can be kept to a certain extent;

2. this application passes through the setting of latch segment, can restrict the body through frictional force and rotate to can further strengthen the stability of head tube.
