Description
Technical field
The utility model relates to a kind of hand barrow, particularly a kind of barrow arresting gear.
Background technology
Hand barrow is widely used in the service location of the mobile operation such as civil aviaton's in-fight service and train, hotel, hospital, hand barrow must be equipped with brake equipment, can brake in time in use and also can decontrol in time braking, to can in use stablize and park, the most important thing is to guarantee hand barrow being perfectly safe in use, therefore barrow arresting gear is than indispensable device in hand barrow.
summary of the invention:
Existing barrow arresting gear, especially the hand barrow of applying on aviation or railway, its brake device structure complexity, and also major part adopts metal casting in a large number, its shortcoming is: design of part complexity, corresponding manufacturing process also complicated, processing capacity is large, cost is high; Heavy Weight; Foundry goods easy fracture, causes fault; Be difficult for maintenance and repair.
Technical problem to be solved in the utility model, designs a kind of barrow arresting gear that can address the above problem exactly.
The technical scheme of technical matters described in the utility model is:
A kind of barrow arresting gear, comprise brake depression bar, cam turntable, brake disc, tie rod, brake pedal, pedal support and pedal reset attachment, described pedal reset attachment is arranged on pedal support, described pedal reset attachment comprises brake off pedal, described pedal reset attachment also comprises reset front apron, reset back shield and retracing spring, described retracing spring links together reset front apron and reset back shield, and described reset back shield and brake off pedal are kept in touch, described brake pedal is all connected with tie rod with releasing brake pedal, when drag, trample brake pedal, described brake pedal drives tie rod motion, tie rod drives cam turntable motion, boss pushing tow brake depression bar on described cam turntable moves, and keep boss to brake depression bar pushing tow state, brake depression bar drives brake disc to move and brake disc is contacted with wheel when movement, make go-cart braking, when brake off, trample brake off pedal, described brake off pedal drives tie rod to move, tie rod drives cam turntable motion, boss on described cam turntable leaves brake lever, remove the pushing tow state of boss to brake depression bar, brake depression bar sets back, brake depression bar drives brake disc to move and makes brake disc leave wheel when setting back, make go-cart brake off state, when boss on described cam turntable leaves brake lever, retracing spring recovers state of nature and drives the motion of reset back shield, and reset back shield drives brake pedal to reset.
Described barrow arresting gear, described brake off pedal, brake pedal are in the time surmounting reset position, and reset front apron makes brake off pedal, brake pedal return to normal reset position under the elastic potential energy effect of retracing spring.
Described barrow arresting gear, described brake off pedal, brake pedal, pedal support adopt enhancing nylon injection-molding part to make.
Described barrow arresting gear, described brake off pedal, brake pedal, pedal support adopt aluminium alloy extrusions to make.
Described barrow arresting gear, described cam is made up of corrosion-resistant steel blanked part.
The beneficial effects of the utility model are: design of part is simple, and processing capacity is little, processing technology is simplified, and cost is low; Reduce the light-duty sturdy material that amount of parts composition and part adopt, and then alleviated weight and part is sturdy and durable; Part high conformity, safe and reliable, assemble easy to maintenance.
