Description

A kind of fork truck Wheel retainer ring structure

Technical field

The utility model relates to non-rice habitats art of wheels, particularly relate to a kind of fork truck Wheel retainer ring structure.

Background technique

Currently, as shown in Figure 1, the inside of existing retaining ring 5 is without protrusion.During wheels travel, existing retaining ring 5 is easy Stress deformation, retainer engaged therewith easily pop up.

Utility model content

The purpose of this utility model is to provide a kind of fork truck Wheel retainer ring structures, hold for solving prior art guide ring The problems such as easy stress deformation and retainer engaged therewith easily pop up.

To achieve the above object, the utility model the following technical schemes are provided:

A kind of fork truck Wheel retainer ring structure, the outside of the retaining ring include outside integrally formed vertical outside and circular arc, The inside of the retaining ring includes integrally formed vertical inner face, protrusion and concave face, the vertical outside and the vertical inner face It is connected by bottom surface.

Wherein, the vertical inner face is circular arc inner face with the join domain of the protrusion.

It wherein, is above circular arc with the join domain of the concave face outside the circular arc.

Wherein, the join domain arc transition between the vertical outside and the bottom surface.

Wherein, the join domain arc transition between the vertical inner face and the bottom surface.

Wherein, the protrusion is connect with the concave face by a plane, and the plane is respectively at the protrusion and institute It is tangent to state concave face.

The above-mentioned technical proposal of the utility model has the beneficial effect that:

In above scheme, the fork truck Wheel retainer ring structure stress of the utility model is unlikely to deform, and prevents the retainer from popping up.

Specific embodiment

In order to make the technical problems, technical solutions and advantages to be solved by the utility model clearer, below in conjunction with attached drawing And specific embodiment is described in detail.

The utility model provides aiming at the problem that existing retaining ring is easy stress deformation and retainer engaged therewith easily pops up A kind of fork truck Wheel retainer ring structure.

As Figure 2-3, the utility model embodiment provides a kind of fork truck Wheel retainer ring structure, the retaining ring 1 Outside includes 12 outside integrally formed vertical outside 11 and circular arc, and the inside of the retaining ring includes integrally formed vertical inner face 13, protrusion 14 and concave face 15, the vertical outside 11 are connect with the vertical inner face 13 by bottom surface 16.

Wherein, the vertical inner face 13 is circular arc inner face 17 with raised 14 join domain.

Wherein, the circular arc outside 12 and the join domain of the concave face 15 are 18 above circular arc.

Wherein, the join domain arc transition between the vertical outside 11 and the bottom surface 16.

Wherein, the join domain arc transition between the vertical inner face 13 and the bottom surface 16.

Wherein, it described raised 14 is connect with the concave face 15 by a plane, and the plane is respectively at the protrusion 14 and the concave face 15 it is tangent.

In the fork truck Wheel retainer ring structure use process of the utility model, seat ring 2 is set on wheel rim 4,1 set of the retaining ring It is located on the seat ring 2, the retainer 3 is set in the groove of the wheel rim 3, the vertical inner face 13,17 and of circular arc inner face Described raised 14 cooperate with retainer 3, play at this point, the retaining ring 1 is close to the retainer 3, described raised 14 and prevent the retainer 3 The effect of pop-up.

Bonding pad between the vertical outside 11 of the fork truck Wheel retainer ring structure of the utility model and the bottom surface 16 Domain arc transition, the join domain arc transition between the vertical inner face 13 and the bottom surface 16 avoid the bottom surface from scratching The seat ring 2 and the retainer 3；The vertical inner face 13 is circular arc inner face 17 with raised 14 join domain, is avoided The retaining ring 1 is concentrated with generation stress in 3 contact process of retainer.

In above scheme, the fork truck Wheel retainer ring structure stress of the utility model is unlikely to deform, and prevents 3 bullet of retainer Out.

All the embodiments in this specification are described in a progressive manner, the highlights of each of the examples are with The difference of other embodiments, the same or similar parts between the embodiments can be referred to each other.
