Description

Universal wheel connecting shaft

Technical Field

The utility model relates to an universal wheel technical field especially relates to an universal wheel connecting axle.

Background

The universal wheel is a movable wheel which is arranged on the bottom bracket of the equipment and can rotate in 360 degrees, and the universal wheel is mainly connected to the bottom bracket through a connecting shaft. The connecting axle both ends of prior art are the flush end to being provided with on the flush end circumference and being used for fixing the connecting axle at the convex recess on end socket seat and universal wheel, but this kind of structure is used for a long time, and the connecting axle is not fine with end socket cooperation effect, and the connecting axle is easy to be followed the end socket seat and is loosened the landing, and then leads to the reliability of universal wheel lower.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the technical problem that will solve is: the universal wheel connecting shaft is high in reliability.

The utility model adopts the technical proposal that: the utility model provides a universal wheel connecting axle, includes the axis body, be provided with the retaining ring that the round is used for blocking the universal wheel on the axis body, axis body one end is the butt, just be provided with on the circumference of butt and be used for installing the convex recess on the universal wheel with connecting axle one end, its characterized in that: the other end of the shaft body is a round platform end, a circle of annular groove is further formed between the bottom of the round platform end and the shaft body, and an annular sealing ring is arranged in the annular groove.

Preferably, the outer circumference of the shaft body is further provided with anti-skid threads.

Preferably, the diameter of the upper end surface of the circular truncated cone end and the depth of the two annular grooves are equal to the diameter of the shaft body.

Compared with the prior art in the structure more than adopting, the utility model has the advantages of it is following: set up a round platform end at the axis body other end, at first can be convenient insert the mop seat through the round platform end like this in to still set up an annular groove, and establish ring type seal on the annular groove, the axis body other end can match through the plastics ring in ring type seal and the end socket seat after inserting the end socket like this, and fixed more is firm, has used for a long time also difficult pine to take off.

Drawings

Fig. 1 is a schematic structural view of a universal wheel connecting shaft.

As shown in the figure: 1. a shaft body; 2. a retainer ring; 3. flattening; 4. a circular arc-shaped groove; 5. a truncated cone end; 6. an annular groove; 7. and (4) anti-skid lines.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

The first embodiment is as follows:

the utility model provides a universal wheel connecting axle, includes

axis body

1, and 1 one end of axis body is flat end 3, and the 1 other end of axis body is round platform end 5, and 1 middle part of axis body is provided with round retaining ring 2, wherein:

a circle of circular arc-shaped groove 4 is formed in the circumference, close to the flat end 3, of the shaft body 1, and the connecting shaft is installed on the universal wheel through the circular arc-shaped groove 4;

a circle of annular groove 6 is arranged on the circumference of the shaft body 1 close to the circular table end 5, a circle of annular sealing ring is arranged in the annular groove 6, and the connecting shaft is arranged on the bottom bracket seat through the annular groove 6 and the annular sealing ring;

the position of the retainer ring 2 is mainly matched with the universal wheel, after the flat end 3 of the connecting shaft is inserted into the universal wheel, the circular arc-shaped groove 4 can be matched with the mounting structure in the universal wheel, and the retainer ring 2 can be flushed with the upper end of the universal wheel.

The working principle of the application is as follows: because the mounting structure in the bottom bracket seat is made of plastic with certain elasticity, the annular groove 6 is matched with the annular sealing ring and the mounting structure, so that the overall reliability is higher, and the loosening failure caused by slight deformation is not easy to occur.

Example two:

the difference from the first embodiment is that in the second embodiment: the outer circumference of the shaft body 1 between the retainer ring 2 and the annular groove 6 is provided with anti-skidding threads 7, so that a user is not easy to skid when installing the connecting shaft, and the installation is more convenient.

Example three:

the difference with the first embodiment is that in the third embodiment, the diameter of the upper end surface of the circular truncated cone end 5 and the depth of the two annular grooves 6 are equal to the diameter of the shaft body 1, which is equivalent to that the upper end surface of the circular truncated cone end 5 is the same as the shaft body 1 without the annular grooves 6, so that the processing is convenient, and the reliability of the shaft body 1 cannot be affected due to the excessive depth of the annular grooves 6.

Although embodiments of the present invention have been shown and described, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention, and that variations, modifications, substitutions and alterations can be made to the above embodiments by those of ordinary skill in the art without departing from the scope of the present invention.

Various alterations and modifications will no doubt become apparent to those skilled in the art after having read the above description. It is therefore intended that the appended claims be interpreted as covering all alterations and modifications as fall within the true spirit and scope of the invention. Any and all equivalent ranges and contents within the scope of the claims should be considered to be within the intent and scope of the present invention.
