Abstract
The invention discloses a kind of bicycle front fork, including main riser, support tube and two branch pipes, main riser is fixedly connected with support tube, support tube is each provided with screwed hole along its axis direction both ends, entity is separated among the screwed hole at both ends, one end outer surface of branch pipe is provided with screw thread, the other end through hole that radially direction is provided through of branch pipe, branch pipe is cased with rubber layer around its through hole, and the outer surface of two branch pipes sets threaded one end to be connected with screwed hole.The bicycle front fork installation of the present invention is stable, is not in the sealing-off problem occurred during bicycle running, and installs rubber sleeve, reduces the damping vibration of bicycle so that ride more steady.
Description
Technical field
The invention belongs to bicycle structure manufacturing field, is related to a kind of bicycle front fork.
Background technology
At present, in the design of bicycle front fork, all junctions of front fork are to be fixedly connected, and are mostly welding, and
In the permanent of bicycle in use, the junction of front fork tends to sealing-off occur, the safety for influenceing bicycle is ridden, in addition,
During the use of front fork, due to no damping device in the structure design of existing front fork, cause to jolt to bicyclist, cause
The fatigue of driver.
The content of the invention
It is an object of the invention to provide a kind of bicycle front fork, solves and is installed present in existing bicycle front fork design
It is unstable, vibrations the problem of.
The technical solution adopted in the present invention is a kind of bicycle front fork, including main riser, support tube and two branch pipes,
Main riser is fixedly connected with support tube, and support tube is each provided with screwed hole along its axis direction both ends, among the screwed hole at both ends
It is separated with entity, one end outer surface of branch pipe is provided with screw thread, the other end through hole that radially direction is provided through of branch pipe,
Branch pipe is cased with rubber layer around its through hole, and the outer surface of two branch pipes sets threaded one end to be connected with screwed hole.
The features of the present invention also resides in,
Main riser, support tube, two branch pipes are shaped as cylinder barred body, and support tubular rod diameter is more than main riser and two
The barred body diameter of branch pipe.
Branch pipe sets threaded one end junction to be provided with a turnover in its outer surface, transfers as round and smooth turnover.
Height of the through hole on two branch pipes is identical, and the height of through hole is less than cycle wheel tire.
Car light is provided with main riser.
A kind of beneficial effect of bicycle front fork of the present invention is：Bicycle front fork installation is stable, is not in cyclery
The sealing-off problem occurred during sailing, and rubber sleeve is installed, reduce the damping vibration of bicycle so that ride more steady.
Brief description of the drawings
Fig. 1 is a kind of structural representation of bicycle front fork of the present invention；
In figure, 1. main risers, 2. car lights, 3. support tubes, 4. screwed holes, 5. branch pipes, 6. through holes, 7. rubber layers, 8. entities.
Embodiment
The present invention is described in detail with reference to the accompanying drawings and detailed description.
A kind of bicycle front fork of the present invention, as shown in figure 1, including main riser 1, support tube 3 and two branch pipes 5, main riser 1
It is fixedly connected with support tube 3, support tube 3 is each provided with screwed hole 4 along its axis direction both ends, is spaced in the screwed hole 4 at both ends
There is entity 8, one end outer surface of branch pipe 5 is provided with screw thread, the other end through hole that radially direction is provided through of branch pipe 5
6, branch pipe 5 at its through hole 6 around be cased with rubber layer 7, the outer surface of two branch pipes 5 sets threaded one end to match somebody with somebody with screwed hole 4
Close connection.
3, two main riser 1, support tube branch pipes 5 are shaped as cylinder barred body, and the barred body diameter of support tube 3 is more than main riser 1
With the barred body diameter of two branch pipes 5.
Branch pipe 5 sets threaded one end junction to be provided with a turnover in its outer surface, transfers as round and smooth turnover.
Height of the through hole 6 on two branch pipes 5 is identical, and the height of through hole 6 is less than cycle wheel tire.
Car light 2 is provided with main riser 1.
A kind of operation principle of bicycle front fork of the present invention is：
Main riser 1 is fixedly connected with support tube 3, and two branch pipes 5 are connected through a screw thread with support tube 3, on support tube 3
Entity 8 is separated among both ends screwed hole 4 so that the threaded connection at both ends is more stable, the height of through hole 6 one on two branch pipes
Cause so that lock is easy to by through hole 6 and to bike locking, while the rubber sleeve 7 of through hole reduces vibrations friction, mitigates
The vibrations of bicycle are unstable.
