[specific embodiment]
See also shown in Figure 1, local assembled sectional view for shock-proof front-fork assembly 10 normal uncompressed of the present utility model, please cooperate the mechanical lock fixing apparatus three-dimensional combination figure when being the utility model shock-proof front-fork assembly 10 normal uncompressed with reference to figure 2, the interior breeches pipe 11 of usual shock-proof front-fork assembly 10 is to fit together two bodys that slide over each other with outer breeches pipe 12, interior breeches pipe 11 installings are connected in the both sides of fork shoulder 14, mechanical lock fixing apparatus 20 main devices are between fork shoulder 14 and interior breeches pipe 11, this securing arrangement 20 includes: a knob 21, swing arm 22, this knob is installed in front fork fork shoulder 14 tops, is linked to an end of swing arm 22; Swing arm 22 other ends link a stops 23; One connection tube 26 is sheathed in the interior breeches pipe 11 of shock-proof front-fork assembly, and these connection tube 26 both sides are provided with groove 27, and these connection tube 26 upper limbs are provided with two relative blocks 28; These stops 23 two ends are provided with flange 231, and these stops 23 belows are provided with cylinder 24, and this cylinder 24 is sheathed in this connection tube 26.
Please cooperate again and consult Fig. 3 and Fig. 4, Fig. 3 is shock-proof front-fork assembly 10 normally-compacted local assembled sectional views of the present utility model, mechanical lock fixing apparatus three-dimensional combination figure when Fig. 4 is the utility model shock-proof front-fork assembly 10 normal compressions, when shock-proof front-fork assembly 10 compressions, interior breeches pipe 11 descends, securing arrangement 20 descends thereupon, stops 23 also descends thereupon, and it is up and down in groove 27,231 limit stop of the flange on stops 23 both sides 23 can not rotated in connection tube 26 with cylinder 24, by Fig. 1 to Fig. 4 the situation of shock-proof front-fork assembly 10 in normal incabloc function running can be described.
Please cooperate again and consult Fig. 5 and Fig. 6, Fig. 5 is the local assembled sectional view during for shock-proof front-fork assembly of the present utility model 10 lockings, mechanical lock fixing apparatus three-dimensional combination figure when Fig. 6 is 10 lockings of the utility model shock-proof front-fork assembly, turn 90 degrees by seeing among Fig. 5 that knob 21 has revolved, swing arm 22 and then revolves and turn 90 degrees, the stops 23 of swing arm 22 other ends also and then revolves and turn 90 degrees as seen from Figure 6 again, the flange 231 on stops 23 both sides is equipped in the stop surface 29 on connection tube 26 upper limb both sides respectively, and the block 28 by both sides limits its swing offset, under the state like this, interior breeches pipe 11 is by whole securing arrangement 20 lockings, can't descend again, form the state that shock-proof front-fork assembly 10 loses incabloc function.
The length of the groove 27 of these connection tube 26 both sides should be greater than the shock-absorbing stroke of shock-proof front-fork assembly, in order to avoid shock-proof front-fork assembly is when implementing incabloc function, by the shock-absorbing stroke of groove length restriction shock-proof front-fork assembly.Groove 27 width of these connection tube 26 both sides should be greater than the width of these stops 23 flanges 231, in order to avoid shock-proof front-fork assembly is when implementing incabloc function, flange 231 is stuck in groove 27.
The thickness of this stops flange 231 should be crossed block 28 to avoid flange 231 less than the height of connection tube upper limb block 28, loses the locking effect.
The utility model is that the incabloc function with the automatic shock-proof front fork gives locked with the mechanical lock fixing apparatus, the user of shock-proof front-fork assembly can have been selected incabloc function or not have incabloc function, but can not adjust the shock-absorbing elasticity modulus, promptly do not have a fine adjustment function yet, only can select shock-absorbing or not have shock-absorbing; But the back-up block of between connection tube 26 bottoms and interior breeches pipe 11 bottoms, installing 30, can select softer elastic body, when incabloc function is locked, still can utilize the elasticity of this back-up block 30, the shock-absorbing vibration-absorbing function of a little is provided, certainly, if back-up block 30 does not have elasticity, whole shock-proof front-fork assembly 10 just do not have shock-proof effect fully when locked incabloc function.
By forming with upper member, this automatic shock-proof front fork is that incabloc function is locked, also can select to open, to adapt to the road surface of different situations, the simple mechanical formula that forms is opened the automatic shock-proof front fork with locked two functions, and comfortable safe driving of user's one tool and the effect of taking can be provided.
