Description

Integrated locking structure of bicycle handle
Technical Field
The utility model belongs to bicycle structure field, concretely relates to an integral type bicycle handle integrated locking structure.
Background
The common integrated bicycle handle adopts a disconnected opening at the head part of a front fork truck connected with a frame in a locking way, namely, a left and right disconnected opening is arranged at the tail end of a body, then the effect of fixing the handle at the head is achieved by locking the opening through a left and right screw, and the locking way of the prior disconnected locked opening needs to be carried out for two times of processing because the opening is needed firstly and then a screw thread hole needs to be processed for two times, so the processing time is longer, the production cost is higher, when the product is used, part of the screw thread is inevitably exposed, the aging and the rusting are caused, the sliding thread is easy to appear during the screwing, the whole part is damaged, in addition, the disconnected bicycle handle has the existence of a disconnected structure, the obvious deformation is caused to be consumed under the condition that the handle is subjected to left and right force application (for example, a user accelerates, and shakes the bicycle handle by the force application of both hands), this is particularly evident in professional racing bicycles, especially in one-piece handlebars made of carbon fiber.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an increase locking strength and can not influence life's integrated bicycle handle locking structure.
In order to realize the above purpose, the utility model discloses a technical scheme be, an integral type bicycle handle integrated locking structure, including handlebar hand and front fork head pipe, its structural feature is that, handlebar hand's central point puts and is equipped with the through hole that is used for passing the front fork head pipe, is equipped with the oppression piece between the inner wall of front fork head pipe and through hole, handlebar hand's lateral wall on be equipped with the lockhole that communicates with the through hole is perpendicular, the lockhole fit in has the tight locking portion in piece and front fork head pipe top of oppressing.
Furthermore, the locking part comprises a nut fixed in the locking hole and a thread mandril screwed in the nut.
Furthermore, the pressing block is a bent plate body, a locking strip is arranged on the side face, contacted with the front fork head pipe, of the pressing block, and a cylindrical blind groove which is coaxial with the lock hole is arranged on the side face, contacted with the inner wall of the through hole, of the pressing block.
Furthermore, the locking strip extends along the axis of the front fork head pipe, the cross section of the locking strip is a triangular strip rod, and the locking strips are a plurality of locking strips which are arranged at equal intervals.
The utility model has the advantages that: through integrating locking portion into inside the handlebar, make the handlebar no longer have the opening, thereby the thread position of screw thread ejector pin is completely in the inside of body and do not expose and avoid rustting, product service life has been improved, owing to need not the opening and reduced the process, the production and processing is also simpler, the efficiency of production has been promoted, compare past open type locking structure, make the handlebar become for complete integrative structure, be superior to past structure on mechanical properties performance, especially on the product with combined material (for example carbon fiber) as the raw materials, combined material's continuity has been kept, make the product have higher use strength than in the past.
Drawings
Fig. 1 is a schematic view of the locking structure of the present invention;
fig. 2 is a schematic view of the structure of the pressing block of the present invention;
the bicycle comprises a bicycle handle 1, a front fork tube 2, a through hole 3, a pressing block 4, a lock hole 5, a screw cap 6, a threaded ejector rod 7, a locking strip 8 and a cylindrical blind groove 9.
Detailed Description
The invention is further explained below with reference to the drawings and the embodiments without limiting the scope of the invention.
Referring to fig. 1 to 2, an integrated locking structure of a bicycle handlebar comprises a handlebar 1 and a front fork tube 2, wherein a through hole 3 for penetrating through the front fork tube 2 is formed in the center of the handlebar 1, a pressing block 4 is arranged between the front fork tube 2 and the inner wall of the through hole 3, a lock hole 5 vertically communicated with the through hole 3 is formed in the side wall of the handlebar 1, and a locking part for tightly pushing the pressing block 4 against the front fork tube 2 is matched in the lock hole 5; different with traditional open type structure, the utility model discloses do not establish the opening at the open position of tradition locking locomotive, and only open a through hole 3, and bury locking portion in lockhole 5, will oppress piece 4 tops on front fork head pipe 2 through locking portion, thereby realize handlebar hand 1 and front fork head pipe 2's locking, just need not the opening because of the locking position at handlebar hand 1, production processes have been reduced, production cost is reduced, also operate more easily on production and processing, and handlebar hand 1 can keep complete closed structure, locking portion also can not lead to rustting because of exposing outside, consequently, product property can be more stable, long service life.
The locking part comprises a screw cap 6 fixed in the locking hole 5 and a thread mandril 7 screwed in the screw cap 6; the threaded ejector rod 7 can be screwed up externally, so that the threaded ejector rod 7 is controlled to extrude the pressing block 4 on the front fork head pipe 2, and the thread part of the threaded ejector rod 7 is completely inside the handlebar 1 and is not exposed, so that rusting is avoided, and the service life of a product is prolonged.
The pressing block 4 is a bent plate body, the side face, contacting with the front fork head pipe 2, of the pressing block 4 is provided with a locking strip 8, the side face, contacting with the inner wall of the through hole 3, of the pressing block 4 is provided with a cylindrical blind groove 9 arranged coaxially with the locking hole 5, the locking strip 8 extends along the axis of the front fork head pipe 2, the section of the locking strip 8 is a triangular strip rod, and the locking strip 8 is a plurality of locking strips 8 which are arranged at equal intervals; when the pressing block 4 is subjected to the jacking force of the threaded mandril 7, the end part of the threaded mandril 7 is jacked in the cylindrical blind groove 9, the rear locking strip 8 is in contact with the front fork head pipe 2, and the locking strips 8 with triangular sections are arranged, so that the pressure applied to the front fork head pipe 2 is large when the locking strips 8 are subjected to the thrust, and the locking strength is improved.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein, and any reference signs in the claims are not intended to be construed as limiting the claim concerned.
