Description
Technical Field
The utility model belongs to the technical field of brake handle technique and specifically relates to a novel adjustable stroke brake handle.
Background
The brake handle is an important part for reducing the running speed of the bicycle so as to respond to the change of road conditions or the distance between the brake handle and an adjacent bicycle when the bicycle is ridden, and the brake handle mainly utilizes the principle of friction force to generate the effect of speed reduction. When the rider presses the brake handle, the brake cable is driven in sequence to move the brake clamping arms, so that the brake pads of the brake clamping arms rub the steel rings to reduce the speed of the bicycle. However, the problem with prior art brake levers is that it is often difficult for a child with a relatively small hand to grip the existing stroller brake lever. The hand holding force of the hand-operated brake is basically close to the holding force of the brake of the adult car, the holding force of the child is relatively small, the action capacity is limited, a large brake torque can be obtained by using a small force when the hand-operated brake is not accurately held away from the center of the brake rotating shaft, the timely braking effect cannot be achieved in an emergency, certain potential safety hazards exist, the structure is not flexible enough, the adjustment cannot be achieved, and the stroke of a brake cable is not enough.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a novel adjustable stroke brake handle is provided.
For solving the above-mentioned prior art problem, the utility model discloses a following scheme: the utility model provides a novel adjustable stroke brake lever, includes brake lever seat, pitman arm and handle, brake lever seat middle part is equipped with first pivot screw and second pivot screw, and first pivot screw and second pivot screw are fixed in on the brake lever seat through the nut, first pivot screw passes the bottom hole and the pitman arm swing joint of pitman arm bottom, the middle part of pitman arm is equipped with the elongated slot, the top of pitman arm is equipped with the line hole of stopping, the handle is connected through the one end of rivet with the hinge, the other end of hinge cooperatees with lock nut through adjusting screw and fixes on the elongated slot at pitman arm middle part, the handle bottom is through second pivot screw and brake lever seat swing joint.
Preferably, the brake lever seat is provided with a brake lever fixing hole, and one side of the brake lever fixing hole is provided with a fixing screw.
Preferably, the brake crank seat is provided with an adjusting hole.
Has the advantages that:
the utility model adopts the above technical scheme to provide a novel adjustable stroke brake handle, remedied the not enough of prior art, reasonable in design, the structure is nimble, convenient the regulation, and laborsaving and stroke are big, make things convenient for children to use.

Detailed Description
As shown in fig. 1, 2, 3 and 4, a novel brake handle with an adjustable stroke comprises a brake handle seat 1, a link arm 4 and a handle 7, wherein a first rotating shaft screw 2-1 and a second rotating shaft screw 2-2 are arranged in the middle of the brake handle seat 1, the first rotating shaft screw 2-1 and the second rotating shaft screw 2-2 are fixed on the brake handle seat 1 through a nut 3, the first rotating shaft screw 2-1 penetrates through a bottom hole in the bottom of the link arm 4 to be movably connected with the link arm 4, a long groove 11 is arranged in the middle of the link arm 4, a brake hole 10 is arranged at the top of the link arm 4, the handle 7 is connected with one end of a hinge 5 through a rivet 6, the other end of the hinge 5 is fixed on the long groove 11 in the middle of the link arm 4 through an adjusting screw 8 and a locking nut 9 in a matching manner, the bottom of the handle 7 is movably connected with the brake handle seat 1 through, the brake lever seat is characterized in that a brake lever fixing hole 13 is formed in the brake lever seat 1, a fixing screw 14 is arranged on one side of the brake lever fixing hole 13, and an adjusting hole 15 is formed in the brake lever seat 1.
As shown in fig. 1, a handle 7 is connected with one end of a hinge 5 through a rivet 6, the other end of the hinge 5 is fixed on a long groove 11 in the middle of a connecting arm 4 through a matching of an adjusting screw 8 and a locking nut 9 to form a linkage structure, when the rivet 6 is riveted, the rivet 6 and the hinge 5 are kept to move smoothly without resistance, the connecting arm 4 is movably connected with a brake lever seat 1 through a first rotating shaft screw 2-1 and a nut 3, the handle 7 is movably connected with the brake lever seat 1 through a second rotating shaft screw 2-2 and a nut 3, a brake wire hole 10 is arranged on the upper portion of the connecting arm 4, a brake wire head passes through the brake lever seat 1 and is clamped into the brake wire hole 10 on the connecting arm 4, when the brake device is actually used, the handle 7 is pulled, the handle 7 drives the connecting arm 4 to rotate around the first rotating shaft screw 2-1 through the hinge 5, the connecting arm, completing the braking process action of the brake handle; as shown in fig. 3, since the lever ratio L2/L1 is greater than 1, a larger movement stroke of the brake cable hole 10 on the link arm 4 can be obtained under the condition that the working range of the handle 7 is smaller, wherein how 1 the stroke is adjusted, different cable strokes can be obtained by inserting a matched tool into a corresponding hole of the adjusting screw 8 from the adjusting hole 12 of the brake lever seat 1 and loosening the adjusting screw 8, then adjusting the up-and-down position of the adjusting screw 8 in the long groove 11 in the middle of the link arm 4, namely changing different lever ratios L2/L1, in addition, a brake lever fixing hole 13 is arranged on the brake lever seat 1, a fixing screw 14 is arranged on one side of the brake lever fixing hole 13, and the whole brake lever can be fixed on the brake lever through the fixing screw 14.
Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
