Description
Technical Field
The utility model relates to a bicycle field refers in particular to a novel compel tight formula riser structure.
Background
Bicycle handlebars are typically connected to a front fork stem via a stem structure to control the steering of the bicycle; although the structure of the bicycle handlebar stem disclosed in the prior art 201020112980.1 reduces the protrusion structure, it can effectively avoid the damage and improve the safety, but has the following problems: 1. the joints of the vertical pipe structure, the front fork vertical pipe and the handlebar are fastened through bolts respectively, so that the disassembly and assembly speed is low; 2. the sleeve ring is tightly fixed at the position of the front fork vertical pipe through the bolt to force the deformation and the bundling, so that the stress on the sleeve ring is large, the sleeve ring is easy to break after long-time work, and the service life is short.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the defects of the prior art and providing a novel packing type vertical pipe structure capable of being quickly assembled and disassembled.
In order to achieve the above purpose, the utility model adopts the technical scheme that: a novel packing type vertical pipe structure comprises a vertical pipe body; one end of the vertical pipe body is provided with a first shaft hole for mounting a front fork vertical pipe, and the other end of the vertical pipe body is provided with a joint front cover fixed through a bolt; a second shaft hole which is perpendicular to the first shaft hole and used for mounting a handlebar is formed between the joint front cover and the vertical pipe body; the first shaft hole is communicated with the second shaft hole, and a fastening block is arranged at the communication position.
Preferably, one side of the tightening block, which is positioned in the first shaft hole, is provided with a first cambered surface; and a second cambered surface is arranged on the other side of the packing block, which is positioned in the second shaft hole.
Preferably, the fastening block is made of an inelastic material.
Preferably, one end of the stand pipe body connected and jointed with the front cover is provided with at least two threaded holes; through holes corresponding to the threaded holes are respectively arranged on the joint front cover; the bolt penetrates through the through hole and is in threaded connection with the threaded hole.
Preferably, the riser body and the joint front cover are both made of light alloy materials or inelastic composite materials.
Because of above-mentioned technical scheme's application, compared with the prior art, the utility model have the following advantage:
1. the utility model has the advantages that the tightening block is arranged at the communication position of the first shaft hole and the second shaft hole, when the bolt is locked, the tightening block can be pushed by the handlebar to extrude the front fork vertical pipe, so that the handlebar and the front fork vertical pipe are fixed simultaneously, the disassembly and assembly speed is greatly improved, and the structure is simple and compact;
2. the utility model discloses can not produce stress when installation handlebar and front fork standpipe, can improve life greatly.
Drawings
The technical scheme of the utility model is further explained by combining the attached drawings as follows:
FIG. 1 is a schematic structural view of a novel packing type riser structure according to the present invention;
fig. 2 is an explosion diagram of the novel packing type vertical pipe structure of the present invention.
Wherein: 1. a riser body; 11. a threaded hole; 2. a first shaft hole; 3. a bolt; 4. engaging the front cover; 41. a through hole; 5. a second shaft hole; 51. a first arc surface; 52. a second arc surface; 6. a packing block; 7. a front fork standpipe; 8. a handlebar.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Fig. 1-2 show a novel packing type vertical pipe structure of the present invention, which comprises a vertical pipe body 1; one end of the vertical pipe body 1 is provided with a first shaft hole 2 for mounting a front fork vertical pipe 7, and the other end of the vertical pipe body is provided with a joint front cover 4 fixed through a bolt 3; a second shaft hole 5 which is perpendicular to the first shaft hole 2 and used for mounting a handlebar 8 is formed between the joint front cover 4 and the stand pipe body 1; the first shaft hole 2 is communicated with the second shaft hole 5, and a fastening block 6 is arranged at the communication position; during installation: insert first shaft hole 2 earlier with front fork standpipe 7 in, will compel tight piece 6 and front fork standpipe 7 laminating again, then insert second shaft hole 5 with handlebar 8 in, screw up bolt 3 at last, promote through handlebar 8 and compel tight piece 6 extrusion front fork standpipe 7, make handlebar 8 and front fork standpipe 7 fixed simultaneously, not only improved dismouting speed greatly, and have advantages such as simple structure, compactness.
Furthermore, a first cambered surface 51 is arranged on one side, located at the first shaft hole 2, of the tightening block 6, so that the tightening block can be conveniently attached to the surface of the front fork vertical tube 7, and a contact surface is increased; the other side of the packing block 6, which is located in the second shaft hole 5, is provided with a second cambered surface 52, so that the packing block can be attached to the surface of the handlebar 8 conveniently, and the contact surface is increased.
Further, compel tight piece 6 to adopt no elastic material to make and form, be convenient for firmly fix handlebar 8 and front fork standpipe 7, and compel tight piece 6 to play the effect that prevents to skid through the alligatoring processing.
Further, threaded holes 11 are respectively formed in four corners of one end, connected and jointed with the front cover 4, of the vertical pipe body 1; four through holes 41 corresponding to the threaded holes 11 are correspondingly arranged on the joint front cover 4; the bolt 3 penetrates through the through hole 41 and is in threaded connection with the threaded hole 11; during installation: the joint front cover 4 can be firmly fixed to the seat tube body 1 by four bolts 3, thereby firmly fixing the handle bar 8 and the front fork stem 7.
Furthermore, the vertical pipe body 1 and the joint front cover 4 are both made of light alloy materials or inelastic composite materials, so that the overall structure is lighter.
The above is only a specific application example of the present invention, and does not constitute any limitation to the protection scope of the present invention. All the technical solutions formed by equivalent transformation or equivalent replacement fall within the protection scope of the present invention.
