Abstract
The utility model discloses a brake mechanism of a baby carriage, which comprises a wheel arranged at the bottom of a carriage frame, a fixing element disposed on the wheel, a groove mounted on the fixing element, a rod element arranged on the carriage frame and a brake rod rotationally disposed on the rod element, wherein the brake rod is provided with a brake device and a brake relieving device, when in a braking position, the brake rod is arranged in the groove, and when in a brake relieving position, the brake rod is separated from the groove, and the brake rod is provided with an operational mechanism which is used to convert the braking position and brake relieving position. Because the brake rod has a small rotation space and usually has a small clearance with the fixing element, the brake mechanism of a baby carriage covers small space.
Description
Technical field
The utility model relates to a kind of braking mechanism of perambulator.
Background technology
In the prior art, the braking mechanism of perambulator, comprise the connecting element that is arranged on the wheel, be opened in groove on the connecting element, be slidingly arranged in the brake lever on the vehicle frame, brake lever injects the brake that realizes wheel in the groove, because brake lever is that to be slidingly arranged in vehicle frame exterior, usually there is very big gap between itself and the connecting element, causes the shared volumetric spaces of the braking mechanism of existing perambulator bigger like this.
Summary of the invention
The purpose of this utility model is to provide the braking mechanism of the less perambulator of a kind of shared volume ratio.
In order to reach above purpose, the technical solution adopted in the utility model is: a kind of braking mechanism of perambulator, comprise the wheel that is positioned at vehicle frame below, be arranged on connecting element on the described wheel, be opened in groove on the described connecting element, be arranged on the rod member on the described vehicle frame, it also comprises the brake lever that is arranged on rotationally on the described rod member, described brake lever has normal danger and un-brake position, when described brake lever was in normal danger, described brake lever was positioned at described groove; When described brake lever was in the un-brake position, described brake lever and described groove were separated, and described brake lever is provided with and is used to control the operating mechanism that this brake lever is changed between normal danger and un-brake position.
Described operating mechanism comprises hauling rope that an end links to each other with described brake lever, links to each other with the other end of described hauling rope and is arranged on the operating parts on the described vehicle frame.
Described operating mechanism also comprises being arranged on and is used to provide this brake lever to be returned to the elastic component of an application force of normal danger from the un-brake position between described brake lever and the described rod member.
Described rod member has cavity, offer opening on the outside face of described rod member, described opening is connected with described cavity, the place of being rotationally connected of described brake lever and described rod member is positioned at described cavity, described opening is stretched out in one end of described brake lever, when described brake lever was in normal danger, an end of described brake lever was positioned at described groove.
Described connecting element comprises a plurality of tooth pieces of arranging around described wheel hub equidistant from distance, and adjacent tooth piece forms described groove.
Because the utility model has adopted above technical scheme, its advantage is:
Brake lever is to be arranged on rotationally on the rod member, rotate brake lever, make brake lever be positioned at groove, realize the brake of wheel, brake lever and groove are separated and realize the un-brake of wheel, because the brake lever rotation space is smaller, the gap between itself and the connecting element is very little usually, causes the shared volumetric spaces of the braking mechanism of perambulator smaller like this.
Description of drawings
Accompanying drawing 1 is for having the scheme drawing of perambulator of the present utility model;
Accompanying drawing 2 is the enlarged drawing at A place in the utility model;
Wherein:
1, wheel; 2, vehicle frame; 3, connecting element; 4, groove; 5, rod member; 6, brake lever; 7, operating mechanism; 8, hauling rope; 9, elastic component; 10, cavity; 11, opening.
The specific embodiment
Further set forth concrete structure of the present utility model and folding process below in conjunction with accompanying drawing.
Shown in accompanying drawing 1-2, a kind of braking mechanism of perambulator, comprise the wheel 1 that is positioned at vehicle frame 2 belows, be arranged on connecting element 3 on the described wheel 1, be opened in groove 4 on the described connecting element 3, be arranged on rod member 5 on the described vehicle frame 2, be arranged on the brake lever 6 on the described rod member 5 rotationally, described connecting element 3 comprises a plurality of tooth pieces of arranging around described wheel 1 wheel shaft equidistant from distance, and adjacent tooth piece forms described groove 4.Described rod member 5 has cavity 10, offer opening 11 on the outside face of described rod member 5, described opening 11 is connected with described cavity 10, described brake lever 6 is positioned at described cavity 10 with the place of being rotationally connected of described rod member 5, described opening 11 is stretched out in one end of described brake lever 6, described brake lever 6 has normal danger and un-brake position, and when described brake lever 6 was in normal danger, an end of described brake lever 6 was positioned at described groove 4; When described brake lever 6 was in the un-brake position, described brake lever 6 was separated with described groove 4, and described brake lever 6 is provided with and is used to control the operating mechanism 7 that this brake lever 6 is changed between normal danger and un-brake position.
Described operating mechanism 7 comprises hauling rope 8 that an end links to each other with described brake lever 6, links to each other with the other end of described hauling rope 8 and is arranged on operating parts on the described vehicle frame 2, be arranged on and be used to provide this brake lever 6 to be returned to the elastic component 9 of an application force of normal danger from the un-brake position between described brake lever 6 and the described rod member 5.Operating operation spare, pulling traction rope 8 drives the rotation of brake lever 6, realizes un-brake, as shown in Figure 2, the unclamp operation part, under the elastic-restoring force effect of elastic component 9, brake lever 6 rotates and is returned in the groove 4, realize brake, because brake lever 6 rotation spaces are smaller, the gap between itself and the connecting element 3 is very little usually, causes the shared volumetric spaces of the braking mechanism of perambulator smaller like this.And the major part of brake lever 6 all is housed in the cavity 10 of rod member 5, so further reduces the volume of braking mechanism.
