[utility model content]
The utility model purpose is the deficiency that has overcome prior art, and go-kart castor lowering or hoisting gear a kind of simple in structure, easy to operate is provided.
The utility model is realized through following technical scheme:
A kind of go-kart castor lowering or hoisting gear; Comprise go-kart base 1; It is characterized in that: on described go-kart base 1, be provided with installing hole 101; Be coated with turn lifters 2 in the described installing hole 101; The inwall of described installing hole 101 is provided with high-order stop position 102 and low level stop position 103; Described turn lifters 2 is provided with the screens projection 201 that can be stuck on described high-order stop position 102 or the low level stop position 103; Be provided with between described high-order stop position 102 and the low level stop position 103 supply described screens projection 201 in described high-order stop position 102 with the slideway that slidably reciprocates 104 of low level stop position 103, described turn lifters 2 belows are connected with castor assembly 4, are provided with between described turn lifters 2 and the described go-kart base 1 top pressure spring 5 of described screens projection 201 elastic compressions on described high-order stop position 102 or low level stop position 103.
Aforesaid go-kart castor lowering or hoisting gear; It is characterized in that: described turn lifters 2 comprises turn cover 202; In the described turn cover 202 castor axle sleeve 203 is housed, is coated with caster axle 401 in the described castor axle sleeve 203, described castor axle sleeve 203 is provided with step 231; Described installing hole 101 lower ends are provided with end cap 106; Described end cap 106 is provided with axis hole 161, and described caster axle 401 is passed described axis hole 161 and is installed on the described castor axle sleeve 203 and can rotates relative to described castor axle sleeve 203, and described top pressure spring 5 roof pressures are between described step 231 and described end cap 106.
Aforesaid go-kart castor lowering or hoisting gear is characterized in that: described turn is overlapped 202 upper ends and is provided with hex shaped groove 221, is fitted with the hexagon bar 205 with its snap-fit in the described hex shaped groove 221, and described hexagon bar 205 is provided with knob 206.
Aforesaid go-kart castor lowering or hoisting gear is characterized in that: described high-order stop position 102 is 3 with low level stop position 103, and described screens projection 201 also corresponds to 3.
Compared with prior art, the utility model has following advantage:
1, the utility model is simple in structure, cooperates turn to go up and down with the go-kart base by the turn cover, and is simple in structure, low cost of manufacture.
All only need turn a lower knob when 2, the utility model need go up and down just can realize; Suppress behaviour by spring after going up and down, the turn cover can not rock, and need the go-kart base not mentioned during adjusting just directly to twist the knob adjusting; Easy to operate, safe and reliable.
