Abstract
The utility model discloses a bicycle front fork spring positioning assembling structure, including an upper fork pipe with an opening set on the bottom, a spring, a lower pipe, as well as a central rod which outer wall is set with circular protuberance and can penetrate the opening. The circular protuberance is fixed in the lower pipe. The spring is penetrated through the central rod, one end is set against on the circular protuberance, and the other end is set against on the bottom of the upper fork inner pipe. The advantage of the utility model merit is that the utility model can solve the default that the elastic force of the common front fork is not smooth, the structure is complex, the production cost is high, etc., because the centering performance of the central rod is higher, the integrated shock absorption effect of the spring is effectively improved, the cost is very low, the production technology is simple, the assembly is rapid, the working time is shortened, and the product defective fraction is reduced.
Description
Technical field
The utility model relates to a kind of Shockproof structure of bicycle, especially front fork spring location structure.
Technical background
The Front fork vibration abatement structure of existing bicycle, as shown in Figure 1, comprise fork 1 and manage 2 down, the interior pipe 3 of fork of going up of wherein going up fork 1 stretches into down in the pipe 2, as shown in Figure 2, manage 2 inner bottom parts down and be fixed with the locking cover 5 that internal thread hole is with at the middle part, pipe 3 is connected by long screw rod 4 with locking cover 5 in the last fork, the pipe bottom is provided with the perforate 10 that can pass screw rod 4 in the last fork, is with spring 6 on the screw rod 4 in last pitching between pipe 3 and the locking cover 5, goes up like this and pitches on 1 spring 6 that is pressed in down in the pipe 2, can alleviate the vibrations that ground is transmitted, this mode technical maturity, matching component is complete, the convenient purchase.But component part is too much, the structure more complicated, and cost is too high; Locking is enclosed within and is difficult for the location when installing, and is easy to generate deflection between the internal thread hole that screw rod and locking put, and causes spring and following inside pipe wall to produce friction; Screw rod is difficult for importing smoothly in the internal thread hole of locking cover when batch manufacturing, causes product quality and production efficiency low.
Summary of the invention
The purpose of this utility model is the defective that overcomes prior art, provides a kind of simple in structure, and assembly is few, and cost is low, can assemble the bicycle front fork spring location package assembly of production efficiency height and quality better fast.
For achieving the above object, technical solution of the present utility model is: bicycle front fork spring location structure, comprise that the bottom is provided with the interior pipe of upward fork, spring, the following pipe of perforate and outer wall is provided with annular protrusion and the center link of perforate can be passed in the top, the annular protrusion of center link is fixed on down in the pipe, spring housing passes center link, one end is against on the annular protrusion, and the other end is against on the bottom of pipe in the fork.
The center link that uses outer wall to be provided with annular protrusion replaces original locking cover and screw rod, reduced assembly, processing becomes easy, reduced cost, the location of center link in following pipe also becomes many easily during assembling, and it is higher to put neutrality, can pressing down of pipe in the last fork be play the guiding role, effectively improve the comprehensive damping effect of spring, the efficient when assembling on a large scale is also higher.
As a kind of prioritization scheme, the top of described center link is connected by the limiting stopper in the pipe in tightening up screw and being located at described upward fork.Can reduce the length of center link like this, guarantee spring when resilience, the top of center link can not deviate to go up the perforate of pipe bottom in the fork because of inertia.
Described annular protrusion is parallel two, and an end of described spring is against by on the last annular protrusion.By two parallel annular teats can better guarantee center link following pipe put middle location, can further improve packaging efficiency and product fine rate.
Described annular protrusion is the nest that is provided with vertical anchor ring and horizontal anchor ring.Vertical anchor ring can play directional tagging when mounting spring, improve packaging efficiency.
Described annular protrusion is the annular ridge of an extrusion forming.During core bar, can form annular ridge so in the mill, reduce assembly, simplify working process by mode from the two ends extruding.
The utility model has the advantages that: the elastic force that can improve dress in the conventional front fork fully has some setbacks, complex structure, defectives such as productive costs is high, because putting of center link is neutral higher, can effectively promote the comprehensive damping effect of spring, and cost is very cheap simultaneously, processing technology is simple, and can assemble fast, shorten man-hour, reduce product fraction defective etc.

The specific embodiment
Embodiment 1: as shown in Figure 3, bicycle front fork spring location structure, comprise the bottom be provided with perforate 10 go up pipe 3 in the fork, spring 4, down manage 2 and the top can pass the center link 7 of perforate 10, parallelly on the center link 7 be provided with two nests 8, each nest 8 is equipped with vertical anchor ring and horizontal anchor ring, vertical anchor ring can play directional tagging when mounting spring, improve packaging efficiency.Center link 7 by by under the horizontal anchor ring of nest 8 be fixed on down on pipe 2 inwalls, spring 4 covers pass center link 7, one ends and are against by on the last nest 8, the other end is against manages in the fork on 3 the bottom.Nest 8 on the center link 7 also can only be established one, and the center link 7 of nest 8 bottoms can cooperate outer tube 2 flattening punching out to become the U-shaped opening.
The top of described center link 7 is connected by the limiting stopper 11 in the pipe 3 in tightening up screw 12 and being located at fork.Can reduce the length of center link like this, guarantee spring when resilience, the top of center link can not deviate to go up the perforate of pipe bottom in the fork because of inertia.
Embodiment 2: as shown in Figure 4, can form two parallel fins 9 by an extrusion forming on the center link 7, one end of spring 6 is against by on the last fin 9, center link 7 by by under fin 9 be fixed on down the pipe 2 in, described fin 9 also can only be established one, and the center link 7 of fin 9 bottoms can cooperate outer tube 2 flattening punching out to become the U-shaped opening.All the other technical characterictics are identical with embodiment 1, do not repeat them here.
