Abstract
The utility model discloses a kind of spanner for railway locomotive jockey, this spanner is connected and composed successively by upper, middle and lower, described middle part is wrench body, this part is a protruding part, and diameter is whole spanner maximum, the bottom of wherein said protruding part is provided with a groove, and the root of this groove is arc transition, and the bottom of described groove is plates; Diameter along described middle part to the end on described top reduces gradually, same, and the diameter along described middle part to the end of described bottom also reduces gradually.The utility model overall construction design is reasonable, prevents stress from too concentrating on R angle, the plates R angle place intensity below groove is improved, prevents phenomenon of rupture, improve service life.
Description
Technical field
The utility model relates to a kind of railway locomotive jockey, and specifically, what relate to is spanner for railway locomotive jockey.
Background technology
Along with the process of urbanization, railway traffic and track traffic development more and more faster, increasing to the demand of train, the spanner of railway locomotive jockey is mainly used in the clutch for clutch control on the jockey between train.
In prior art, for the ease of processing with face and side cutter when the wrench products of railway locomotive jockey designs, requirement is not done at the R angle of groove root, cause product in use, due to R angle too little (generally only having about 0.5), stress too concentrates on R angle, makes the plates R angle place below groove produce fracture, causes disabler.
Utility model content
The purpose of this utility model is to solve above-mentioned deficiency of the prior art, provides a kind of spanner of railway locomotive jockey, the plates R angle place intensity below groove is improved, prevents phenomenon of rupture, improve service life.
For realizing above-mentioned object, the spanner of a kind of railway locomotive jockey described in the utility model, this spanner is connected and composed successively by upper, middle and lower, described middle part is wrench body, this part is a protruding part, and diameter is whole spanner maximum, and the bottom of wherein said protruding part is provided with a groove, the root of this groove is arc transition, and the bottom of described groove is plates; Diameter along described middle part to the end on described top reduces gradually, same, and the diameter along described middle part to the end of described bottom also reduces gradually.
Preferably, the upper end of described protruding part and junction, described top are arc transition.
Preferably, the lower end of described protruding part and junction, described bottom are right angle.
Preferably, one end away from middle part of described top and described bottom is provided with connector.
Preferably, the diameter on described top is greater than the diameter of described bottom, but is less than the diameter at described middle part.
The utility model beneficial effect:
The utility model carries out design to technology to be improved, and overall construction design is reasonable; Make the plates R angle place intensity below groove improve simultaneously, prevent phenomenon of rupture, improve service life.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In figure: top 1, middle part 2, bottom 3, protruding part 4, groove 5, plates 6.
Detailed description of the invention
Below in conjunction with drawings and Examples, the technical solution of the utility model is further explained, but following content is not used in restriction protection domain of the present utility model.
As shown in Figure 1, the present embodiment provides a kind of spanner of railway locomotive jockey, this spanner is connected and composed successively by top 1, middle part 2 and bottom 3, described middle part 2 is wrench body, this part is a protruding part 4, and diameter is whole spanner maximum, and the bottom 3 of wherein said protruding part 4 is provided with a groove 5, the root of this groove 5 is arc transition, and the bottom 3 of described groove 5 is plates 6; Diameter along described middle part 2 to the end on described top 1 reduces gradually, same, and the diameter along described middle part 2 to the end of described bottom 3 also reduces gradually.
As a preferred embodiment, upper end and the junction, described top 1 of described protruding part 4 are arc transition.
As a preferred embodiment, lower end and the junction, described bottom 3 of described protruding part 4 are right angle.
As a preferred embodiment, one end away from middle part 2 of described top 1 and described bottom 3 is provided with connector, for being connected with miscellaneous part.
As a preferred embodiment, the diameter on described top 1 is greater than the diameter of described bottom 3, but is less than the diameter at described middle part 2.
The utility model carries out design to technology to be improved, reasonable in design, middle part 2 largest diameter, provide intensity, the root of middle part 2 protruding parts 4 times square grooves 5 uses arc transition completely, make the R angle place intensity of the plates 6 below groove 5 improve simultaneously, prevent phenomenon of rupture, improve service life.
Although content of the present utility model has done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to restriction of the present utility model.After those skilled in the art have read foregoing, for multiple amendment of the present utility model and substitute will be all apparent.Therefore, protection domain of the present utility model should be limited to the appended claims.
