Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

A hub cap mounting structure, as shown in FIG. 1 to FIG. 4, includes a hub 2, a hub cap 1, a mounting groove 21 is formed on an outer end surface of the hub 2, the hub cap 1 is mounted on the mounting groove 21, a lower end of the hub cap 1 has two or more buckles 3, it should be noted that the number of the buckles 3 can be plural, in this embodiment, two buckles 3 are preferred due to the assembly specificity of the buckles 3, and the two buckles 3 are arranged oppositely along a horizontal direction, a plurality of limit blocks 4 corresponding to positions of the buckles 3 one by one are arranged on a side wall of the mounting groove 21, the buckles 3 can be clipped into the lower ends of the limit blocks 4 corresponding to the buckles 3, specifically, the buckles 3 have an elastic block 31 and a limit protrusion 32 which are integrally formed, a first extrusion block 41 and a second extrusion block 42 capable of extruding the elastic block 31 are further arranged on the side wall of the limit blocks 4, a joint region 43 capable of jointing with the elastic block 31 is formed between the first extrusion block 41 and the second extrusion block 42, it should be noted that the fitting herein includes a pressing condition, that is, the elastic block 31 can be in a non-pressing state or a pressing state after the installation is completed, and when the elastic block 31 is in the non-pressing state, the outer side surface of the elastic block 31 is required to be just ensured to abut against the fitting region 43, so as to prevent the hub cover 1 from shaking during the operation due to the gap.

For the installation of the above-mentioned buckle 3 and the stopper 4, the stopper 4 may also be a case without the first pressing block 41 and the second pressing block 42, specifically, for example, the number of the buckle 3 is two, the number of the stopper 4 is two, one stopper 4 has the first pressing block 41 and the second pressing block 42, and the other stopper 4 does not have, which may also achieve the effect, but compared with the solution in the present embodiment, the stability of the above-mentioned manner is greatly reduced, which belongs to the improved design, and thus, the protection scope of the present invention also belongs to.

The lateral wall of elastic block 31 can support with laminating region 43 and lean on, and spacing arch 32 is located the outside of elastic block 31, and spacing arch 32 can support with the lower terminal surface of stopper 4 and lean on, specifically, when buckle 3 installed in place, spacing arch 32 can't be deviate from stopper 4 passively.

The up end of stopper 4 is provided with from high and low direction sloping platform 5, the highest point of direction sloping platform 5 laminates with the lateral wall of mounting groove 21 mutually, the lowest point of direction sloping platform 5 is located the outside edge of stopper 4, specifically, this direction sloping platform 5 is as the transition device that buckle 3 impressed, if buckle 3 directly impresses, can produce great wearing and tearing between spacing arch 32 and the stopper 4, and the power that needs to use also can be very huge, and through the inclined plane of direction sloping platform 5 behind the use direction sloping platform 5, spacing arch 32 can directly slide in to the below of stopper 4, can not produce great wearing and tearing.

Mounting hole 22 has been seted up at wheel hub 2's center, mounting hole 22 runs through mounting groove 21, install drive shaft 6 in the mounting hole 22, the end of drive shaft 6 runs through mounting hole 22 and threaded connection has nut 7, specifically, drive shaft 6 is terminal to run through in mounting hole 22 reachs mounting groove 21, it is fixed through nut 7, nut 7 also is located mounting groove 21 this moment, wheel hub lid 1 can effectively protect nut 7, prevent that outside steam silt etc. from entering into to mounting groove 21 in and causing the pollution to nut 7.

The mounting sleeve 8 is mounted inside the mounting hole 22, the first assembling groove 9 is formed in the driving shaft 6, the second assembling groove 10 is formed in the inner cavity of the mounting sleeve 8, the first assembling groove 9 and the second assembling groove 10 are matched to form a pin hole 11, and the linkage pin 12 is inserted into the pin hole 11.

Two mounting manners of the mounting sleeve are listed below, the first manner is that the inner wall of the mounting hole 22 is provided with a plurality of longitudinal protrusions 13, the outer side wall of the mounting sleeve 8 is provided with longitudinal grooves 15 corresponding to the longitudinal protrusions 13, the longitudinal protrusions 13 can be clamped into the longitudinal grooves 15, the inner wall of the mounting hole 22 is provided with a plurality of transverse protrusions 14, the outer side wall of the mounting sleeve 8 is provided with transverse grooves 16 corresponding to the transverse protrusions 14, the transverse protrusions 14 can be pressed into the transverse grooves 16 in an interference fit manner, it should be noted that the plurality of protrusions are all integrally formed, and the second manner is different from the first manner in that the mounting hole 22 of the second manner does not have a transverse groove and a longitudinal groove, but is formed by firstly putting the mounting sleeve with the transverse protrusion into the mounting hole 22 and then matching with a die-casting process, after completion, the transverse and longitudinal grooves are also extruded into the mounting holes 22, and the mounting holes 22 are tightly fitted with the mounting sleeve 8, and the second mode is preferred as the best solution in this embodiment.

The outer side of the hub 2 is also provided with a rim 17 and spokes 18, the spokes 18 being used to connect the hub 2 and the rim 17.

The working principle is as follows: when installation wheel hub lid 1, the user can directly aim at buckle 3 and press at laminating region 43 of stopper 4, when taking out wheel hub lid 1, the user can hold between the fingers the both sides of wheel hub lid 1 to the one hand and make wheel hub lid 1 carry out clockwise or anticlockwise rotation, extrusion piece one 41 or extrusion piece two 42 can cause the extrusion to elastic block 31 when the equidirectional, make elastic block 31 produce deformation, through the rotation of equidirectional not equidirectional many times and apply outside pulling force in addition, make buckle 3 can deviate from stopper 4, accomplish the separation of wheel hub lid 1, finally, it is more convenient to make the dismouting.
