Abstract
The utility model discloses a wheelbarrow gear brake which is composed of a frame, a wheel, a wheel frame, a gear, a rack, a spring, a drawing wire, and a handle. The wheel frames are fixed on the frame, the wheel and the gear are connected into integral body and the integral body is connected with the wheel frame via a pin shaft, the rack passes through a supporting frame and is joggled with the gear, the spring is arranged at back part of the rack, and one end of the drawing wire is connected with rear end of the rack and the other end is connected with the handle. The utility model has the advantages of convenient operation, and capability of stopping the wheelbarrow rapidly and controlling speed of the wheelbarrow. When braking, the handle is released and the spring drives the rack to move spring forwards so as to fastening the gear to stop the wheelbarrow; or the handle is moved and the rack is released from the gear to move the wheelbarrow forwards continuously.
Description
The utility model belongs to a kind of car brake.
Present waggon and the go-cart of various bin formula generally all do not have drg, and this will be difficult to control by waggon when pushing heavier goods, particularly all the more so when the dolly descending, overturns accident through regular meeting, even can cause danger.
The purpose of this utility model is: a kind of car brake is provided, and it can realize the braking of dolly easily, avoids the problems referred to above to occur.
The utility model is to constitute like this: it is by vehicle frame (1), wheel (2), wheel carrier (3), gear (4), tooth bar (5), spring (6), backguy (7), handle (8) is formed, and wheel carrier (3) is fixed on the vehicle frame (1), wheel (2) is connected as a single entity with gear (4), and be connected with wheel carrier (3) by bearing pin, tooth bar (5) passes support (9) and gear (4) engagement, and spring (6) is equipped with at its rear portion, one end of backguy (7) connects the rear end of tooth bar (5), and the other end connects handle (8).
The utility model compared with prior art has flexible operation, can dolly be stopped, and can control advantages such as the dolly speed of a motor vehicle.Glancing impact, release handle, tooth bar blocks gear forward under the effect of spring, dolly is stopped, and pulls handle, and tooth bar withdraws from from gear, and dolly continues to move ahead.
Accompanying drawing 1 is a constructional drawing of the present utility model.
Embodiment of the present utility model: wheel carrier (3) is fixed on the vehicle frame (1), wheel (2) is made of one with gear (4), be through on the wheel carrier (3) with bearing pin, tooth bar (5) passes support (9) and gear (4) engagement, spring (6) is loaded onto at its rear portion, support (9) is fixed on the vehicle frame (1), and an end of backguy (7) connects the rear end of tooth bar (5), and the other end connects handle (8).
