The utility model aims at: the utility model provides a prevent bumping location axle, make the length adjustment of center pin more nimble and increase wear-resisting plastics at the last head of center pin and base body and protect, PE plastics can contact the wheel hub centre bore preferentially when the wheel hub is got to the dress, and to a great extent has reduced the wheel hub centre bore and has bruised.
The technical scheme for realizing the purpose is as follows: an anti-collision positioning shaft comprises a base, wherein the base comprises
The center of the base body is provided with a shaft hole; the shaft sleeve part is arranged on one surface of the base body, and a central shaft hole of the shaft sleeve part is communicated with and aligned to a shaft hole on the base body; the protective sheet is arranged on the other surface of the base body; the protective sheet is coated at one end, penetrating through the shaft hole of the base body, of the central shaft.
In a preferred embodiment of the present invention, the base body is provided with a screw hole at one side where the protection sheet is assembled, and the protection sheet is fixed to the screw hole by a screw.
In a preferred embodiment of the present invention, the base body is provided with a groove in the middle of one surface of the protection sheet, the protection sheet is provided with a protrusion on one surface contacting with the base body, the protrusion is embedded into the groove, and the protrusion is fit with the groove.
In a preferred embodiment of the present invention, the protection sheet is made of polyethylene.
In a preferred embodiment of the present invention, the protection sheet completely covers a surface of the base body contacting the protection sheet.
The utility model has the advantages that: the utility model discloses a prevent bumping location axle, the length adjustment that can make the center pin is more nimble and increase wear-resisting plastics at the last head of center pin and base body and protect, and PE plastics can the preferred contact wheel hub centre bore when the wheel hub is got to the dress, and to a great extent has reduced the wheel hub centre bore and has collided.

The invention is further explained below with reference to the figures and examples.
Fig. 1 is a schematic view of a mounting structure of a protection sheet of an anti-collision positioning shaft according to an embodiment of the present invention.
Fig. 2 is a schematic view of an installation structure of the anti-collision positioning shaft according to the embodiment of the present invention.
Wherein,
1, a base; 2, a protective sheet; 3, a hub;
11 seat bodies; 12 a boss portion; 13, grooves;
21 a raised portion.
Detailed Description
The following description of the embodiments refers to the accompanying drawings for illustrating the specific embodiments in which the invention may be practiced. In the present invention, directional terms such as "up", "down", "front", "back", "left", "right", "top", "bottom", etc. refer to directions of the attached drawings only. Accordingly, the directional terms used are used for describing and understanding the present invention, and are not used for limiting the present invention.
Example (b): as shown in fig. 1 and 2, an anti-collision positioning shaft includes a base 1, a fastening mechanism, a central shaft, and a protection sheet 2.
In this embodiment, the base 1 includes a base body 11 and a boss portion 12. The shaft sleeve part 12 is arranged on one surface of the base body 11, and a shaft hole is formed in the center of the shaft sleeve part 12, extends to the base body 11 and penetrates through the shaft sleeve part 12 and the base body 11. Still be equipped with the mounting hole on the base body 11, the mounting hole distribute in the one side of base body 11, the mounting hole with axle sleeve portion 12 is located the same face of base. The mounting hole is used for mounting the central positioning shaft at a specified position.
In this embodiment, the fastening mechanism (not shown) is disposed on the boss portion 12. The fastening mechanism includes a fastening hole extending from the outer periphery of the boss portion 12 to the inside (in the shaft hole) of the boss portion 12, and a fastening screw; the fastening screw is assembled in the fastening hole. And a plurality of groups of fastening holes and fastening screws are correspondingly arranged. The two groups of fastening holes are arranged in the embodiment, and the fastening holes are uniformly distributed along the shaft body direction of the shaft sleeve part 12.
In this embodiment, the central shaft is telescopically assembled in the shaft sleeve, the central shaft is fixed to the base through the fastening mechanism, and one end of the central shaft is provided with a positioning hole groove.
In this embodiment, the protection sheet 2 is disposed on the other surface of the base body; the protective sheet 2 covers one end of the central shaft which penetrates through the shaft hole of the base body. The base body is assembling one side of protection piece 2 is equipped with screw hole and recess 13, protection piece 2 with the one side of base body contact is equipped with bellying 21, bellying 21 imbed in the recess 13, the size of this bellying 21 coincide in recess 13, protection piece 2 is fixed in through the screw hole. The protection sheet 2 is made of polyethylene material.
The protection sheet 2 completely covers one surface of the base body, which is contacted with the protection sheet 2, and the protection sheet 2 completely covers one surface of the base body, which is contacted with the protection sheet 2.
When the length adjusting device is used, if the length of the central shaft needs to be adjusted in case of repositioning, the length of the central shaft can be adjusted only by loosening the two fastening screws on the base. And after the screw is adjusted to a proper position, the screw is locked.
When the hub 3 is assembled and disassembled, the protective sheet 2 made of Polyethylene (PE) plastic can preferentially contact the center hole of the hub 3, so that the central shaft steel material part is prevented from colliding with the center of the hub 3.
