Detailed Description
The present invention will be described in further detail with reference to the following embodiments and accompanying drawings.
A brake pump clevis joint structure as shown in figures 1 to 3 comprises a brake arm 4, a clevis 3 and a brake pump ejector rod 6, and is characterized in that: the spring lock plate is characterized by further comprising a spring lock plate 1 and a pin shaft 2, wherein one end of the spring lock plate 1 is a plane part, the other end of the spring lock plate is provided with an encircling spring hoop 11, a pin shaft mounting hole 12 is formed in the plane part, and the pin shaft 2 is riveted in the pin shaft mounting hole 12; the spring hoop 11 is of a cylindrical curved surface structure, an opening is formed in the side face of the spring hoop, and the center line of the spring hoop is perpendicular to the center line of the pin shaft 2; the pin shaft 2 is inserted into the mounting holes of the brake arm 4 and the connecting fork 3, and the cylindrical table of the connecting fork 3 is embedded into the spring hoop 11; the brake pump mandril 6 is connected in the screw hole of the connecting fork 3 through the locking nut 5.
Furthermore, the edge of the plane part of the spring locking plate 1 is provided with a flanging structure 13 which is perpendicular and outward.
Furthermore, an outward crimping structure 14 is arranged at the opening of the spring hoop 11.
The utility model discloses during the use, with round pin axle 2 and the riveting combination of spring locking plate 1, only need with round pin axle 2 assembly back in place, press the spring staple bolt 11 structure of spring locking plate 1, make it embrace the cylinder platform of connecting fork 3 can.
The pin shaft 2 is connected with the spring locking plate 1 in a riveting mode, the pin shaft 2 and the spring locking plate 1 cannot move axially, the edge turning structure 13 is arranged on the edge of the plane part on the spring locking plate 1, the spring locking plate 1 is prevented from withdrawing from the pin shaft 2 due to elastic deformation, and the connection reliability is high.
The tail end of the spring locking plate 1 adopts an encircling spring hoop 11 structure, a curling structure 14 is arranged at the opening of the spring hoop 11, so that the assembly is convenient, the opening is directly aligned to the cylindrical table of the connecting fork 3 during the assembly, and the spring hoop 11 is pressed forcibly to enable the cylindrical table of the connecting fork 3 to be embraced. When the dismounting is carried out, the pin shaft 2 can be taken out along the situation only by withdrawing the spring anchor ear 11.
In the assembling and disassembling process, the spring locking plate 1 only generates elastic deformation, so the disassembling and assembling connecting fork 3 has no influence on the service life of the structure. Not only the assembly step is simple, and in appearance, this connection structure is more succinct than traditional split pin locking structure.
The technical solutions provided by the embodiments of the present invention are described in detail above, and the principles and embodiments of the present invention are explained herein by using specific examples, and the descriptions of the above embodiments are only applicable to help understand the principles of the embodiments of the present invention; meanwhile, for a person skilled in the art, according to the embodiments of the present invention, there may be variations in the specific implementation manners and application ranges, and in summary, the content of the description should not be construed as a limitation to the present invention.
