Support sledTechnical field
The invention belongs to ice-sports instrument field, be specifically related to a kind of support sled.
Background technology
Sled motion is to integrate body-building and the sports items entertained, support sled is the one of sled, it is to hold strut support ice face by both hands to promote support sledge to slide, limited less by orographic factor, can using at descending, flat slope and relatively slow upward slope, so deeply being liked by vast ice-sports fan, it is big to there is weight in existing support sledge, turn to rudder weight cannot adjust and safeguard the problems such as inconvenience, reduce safety and the service life of support sledge.
Summary of the invention
The invention aims to solve above-mentioned existing support sledge Problems existing, it is provided that a kind of support sled, its technical scheme is as follows:
A kind of support sled, it comprises seat, carrier, directed skates and steering gear, seat is arranged on carrier, it is arranged below directed skates at carrier, the front of carrier is provided with steering gear, steering gear comprises supporting plate, steering spindle, turns to skates and turn to pedal, supporting plate is provided with steering spindle, supporting plate be arranged below turn to skates, skates are turned to be connected by Hooks coupling universal coupling with the lower end of steering spindle, being provided above two and turn to pedal at supporting plate, two both sides turning to pedal to lay respectively at steering spindle also fixing with steering spindle are connected；Seat is rotationally connected along the direction of front and back folding with carrier, arranges an axostylus axostyle on carrier, and axostylus axostyle is fixing with carrier to be connected, and fills an axle sleeve at shaft rod upper sleeve, and axle sleeve is fixing with seat to be connected；Carrier and directed skates grafting, and it is provided with positioner between carrier and directed skates, carrier is provided with slot, directed skates are provided with the plate adapted with slot, owing to the maintenance period of directed skates is longer, positioner adopts alignment pin or bolt etc.；Seat or axle sleeve are connected by expansion link with supporting plate, expansion link is provided with multiple-length device for limiting, owing to the distance between seat and steering gear wants the frequent height adjustment according to every user, so multiple-length device for limiting adopts spring detent, one telescopic end of expansion link is fixing with seat or axle sleeve to be connected, another telescopic end of expansion link is fixing with supporting plate to be connected, the telescopic end being connected with seat or axle sleeve of expansion link is also connected by damping with carrier, damping comprises amortisseur and length adjustment screw rod, one end of amortisseur is hinged with carrier, length adjustment screw rod is arranged on the other end of amortisseur, the axis of length adjustment screw rod is with the axis of amortisseur point-blank, one end of length adjustment screw rod is connected threadably with amortisseur, the other end of length adjustment screw rod is hinged with expansion link and is connected along circumferentially rotating of screw rod；Length adjustment screw rod is provided with handwheel, it is simple to manually adjust the length of damping；Supporting plate is provided with guard rail.
The invention have the benefit that simple in construction, lightweight, cost is low；Damping improves ride quality, and can adjust, by the length of change damping, the pressure turning to skates to ice face, it is achieved thereby that turn to the adjustment of rudder weight, it is ensured that turning sensitivity and stability, improves safety；Directed skates are easy to dismounting, maintain easily；Guard rail can play protective action, also has windage little, and cost is low, is hardly damaged and advantage easy to maintenance.
