Abstract
The invention discloses a chassis foot mechanism which comprises a beam and further comprises supporting columns, wheels, brake pads and steel wires. The two ends of the beam are rotationally connected with the two supporting columns respectively. The wheels are arranged at the bottom ends of the supporting columns respectively. The supporting columns at the front end are provided with fixing columns which are rotationally connected with the brake pads. The front ends of the brake pads are matched with the side faces of the wheels. The rear end of each brake pad is connected with one end of the corresponding steel wire. The other end of each steel wire is connected with the corresponding supporting column on the same side as the steel wire. When the chassis foot mechanism is raised, the steel wires tension the brake pads, and the wheels are locked. When the chassis foot mechanism is pressed downwards, the state of the brake pads can be adjusted through the steel wires according to different down-pressing force, and therefore slow braking or flat ground rolling are achieved.
Description
Technical field
The present invention relates to a kind of chassis pin mechanism, belong to four-wheel kinematic mechanism technical field.
Background technology
At present, be all straight-bar bottom crutch, when walking need crutch to mention, during use, very difficultly, if can add four-wheel kinematic mechanism, realization body supports crutch and ground surface is advanced, and user will be very laborsaving.But common idler wheel mechanism, cannot realize brake function, need further to improve.
Summary of the invention
Object: in order to overcome the deficiencies in the prior art, the invention provides a kind of chassis pin mechanism.
Technical scheme: for solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of chassis pin mechanism, comprise crossbeam, also comprise pillar, wheel, brake facing, steel wire, described crossbeam two ends are respectively rotatably connected to two pillars respectively, and every root pillar bottom is provided with wheel; Described front stanchion arranges fixed leg, and described brake facing and fixed leg are rotationally connected; Match with wheel lateral location in described brake facing front end, brake facing rear end is connected with steel wire one end, and the steel wire other end is connected with same lateral brace.
Also comprise stop gear, described same lateral brace and crossbeam junction are provided with stop gear, rotate maximum angle for controlling with lateral brace.
Described brake facing is set to L-type.
Also comprise three-dimensional connector, described three-dimensional connector is arranged in the middle part of crossbeam.
Preferably, described brake facing quantity is set to two.
Preferably, described two brake facings are all arranged on two pillars of front end.
Beneficial effect: a kind of chassis pin mechanism provided by the invention, when chassis pin mechanism lifts, Wire pulling brake facing, reaches the state of locked wheel; When chassis pin mechanism presses down, steel wire according to the difference of downforce, can regulate the state of brake facing, realizes slowly brake or level land rolling.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described.
As shown in Figure 1, a kind of chassis pin mechanism, comprises crossbeam 1, also comprises pillar 2, wheel 3, brake facing 4, steel wire 5, and described crossbeam 1 two ends are respectively rotatably connected to two pillars 2 respectively, and every root pillar 2 bottom is provided with wheel 3; Described front stanchion 2 arranges fixed leg 6, and described brake facing 4 is rotationally connected with fixed leg 6; Match with wheel 3 lateral location in described brake facing 4 front end, brake facing 4 rear end is connected with steel wire 5 one end, and steel wire 5 other end is connected with same lateral brace 2.Also comprise stop gear 7, described same lateral brace 2 is provided with stop gear 7 with crossbeam 2 junction, rotates maximum angle for controlling with lateral brace 2.Also comprise three-dimensional connector 8, described three-dimensional connector 8 is arranged in the middle part of crossbeam 1.
Concrete occupation mode is as follows: when chassis pin mechanism presses down, be that rotating shaft outwards expands angle with lateral brace with crossbeam, but when reaching maximum angle, by stop gear effect, maintain static, now, brake facing rear end pulls back by the steel wire be connected on pillar, brake facing is taking fixed leg as rotating shaft, and the other end away from wheel, thus realizes the rolling of wheel on ground.When chassis pin mechanism is carried, reclaim with lateral brace, steel wire is not pulling brake facing rear end, and brake facing front end contacts with wheel, plays the effect of brake.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
