Detailed Description
The invention is realized by the following technical scheme.
A system internal force braking mechanism comprises a frame 1, a limiting pin 2, a nut 3, a directional wheel 4, a fixing pin 5, a universal wheel 6, a directional wheel shell 7, a retaining rod connecting pin 8, a retaining rod 9, a spring 10, a sleeve 11 and a mandrel 12.
The front end below the frame 1 is provided with 2 round holes for installing 2 directional wheels 4, and is fastened on the frame 1 by nuts 3. The rear end below the frame 1 is provided with 2 round holes for installing 2 universal wheels 6, and the universal wheels are fastened on the frame 1 by nuts 3.
The upper end of the directional wheel shell 7 is provided with 1 threaded step shaft which is used for being hinged and fixed on the frame 1, 1 operating rod T is arranged on the directional wheel shell 7 for facilitating the rotation operation of the directional wheel 4, the operating rod T is arranged on the outer side of the directional wheel shell 7 for facilitating the operation, and the operating rod T can be designed at other positions according to actual conditions as long as the directional wheel 4 can be driven to rotate. The front end of the directional wheel shell 7 is provided with 1 arc-shaped groove U, and a limiting pin 2 or a protruding structure on the frame 1 slides in the arc-shaped groove U to realize the limit of the directional wheel 4 in a walking state and a braking state; the limiting pin 2 or the protruding structure can also be arranged on the steering wheel shell 7, and the arc-shaped groove U is arranged on the frame 1, so that the limiting pin 2 or the protruding structure can slide in the arc-shaped groove U and limit the steering wheel. At the rear end of the orienting wheel housing 7, 1 retaining lever 9 is articulated by a retaining lever connecting pin 8.
The retaining rod 9 is a telescopic assembly comprising a sleeve 11, a spindle 12 and a spring 10. The end of the sleeve 11 is provided with 1 clamping groove K and 1 through hole M for hinging with the rear end of the directional wheel shell 7, and the end of the mandrel 12 is provided with 1 groove H for matching with the fixing pin 5 on the frame. When the axis of the sleeve 11, spindle 12 and spring 10 passes the turning point of the orienting wheel 4, the spring 10 is at the compression limit. When the orientation wheel 4 is rotated to the "running state", the axes of the sleeve 11, the mandrel 12 and the spring 10 slide past the turning point of the orientation wheel 4 and deviate a certain distance, and the sleeve 11 and the mandrel 12 move away from each other due to the elastic force of the spring 10 after the sleeve 11 and the mandrel 12 pass the movement dead point, so that the spring 10 can provide a certain running state maintaining force for the orientation wheel. When the directional wheel 4 is rotated to a 'braking state', the axes of the sleeve 11, the mandrel 12 and the spring 10 reversely slide through the turning point of the directional wheel and deviate a certain distance, and the sleeve 11 and the mandrel 12 are moved away from each other by the elastic force of the spring 10 after the sleeve 11 and the mandrel 12 pass through a motion dead point, so that the spring 10 can provide a certain braking state maintaining force for the directional wheel.
The working process is as follows:
the braking process comprises the following steps: when the brake is needed, 2 directional wheels 4 are rotated inwards by a certain angle through a tool or manually, the rolling directions of the 2 directional wheels cannot be kept consistent, and then the structure is locked and cannot rotate, namely the purpose of braking is achieved, and meanwhile, the state of the directional wheels 4 is kept by the retaining rod 9 under the action of the spring 10.
Resetting: when the brake needs to be released, the steering wheel which has been rotated is reversely rotated to the initial position by reversely rotating 2 directional wheels 4 by a tool or manually, and simultaneously the holding lever 9 holds the directional wheels 4 in state under the action of the spring 10.
The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly, and are not intended to limit the scope of the present invention, but all equivalent changes or modifications made according to the spirit of the present invention should be included in the scope of the present invention. The technology, shape, and construction parts of the present invention, which are not described in detail, are known in the art.
