CN203717582U - Sliding groove insert - Google Patents

Abstract

The utility model discloses a sliding groove inserts. The center of a block shoulder and an insert block is provided with a radial round hole, the inner side of the round hole is provided with internal threads, the surface area of the block shoulder is smaller than that of the insert block, both ends of the insert block are slide groove inserting shoulders, and the connecting edges of the insert block and the block shoulder are arc transitional surfaces. By means of reasonable design, the insert can be well matched with a sliding groove, and the surfaces of the insert in contact with the groove are of an arc surface structure, so that the insert can slide smoothly and avoid groove locking. The sliding groove insert has the advantages of being reasonable in design and avoiding groove locking.

Description

A kind of chute inserts

Technical field

The utility model belongs to field of mechanical technique, is specifically related to a kind of chute inserts.

Background technique

Existing chute inserts all need to be put into from one end corresponding chute, but because the design of existing chute inserts is unreasonable, the phenomenons such as draw-in groove usually occurs in loading procedure, has affected practical efficiency.

Summary of the invention

The purpose of this utility model is to design a kind of chute inserts.

To be solved in the utility model is unreasonable, the easy draw-in groove problem of existing chute inserts design.

The technical solution of the utility model is: comprise abaculus and the shoulder being connected as a single entity with abaculus, be provided with radially circular hole in the middle of described shoulder and abaculus, circular hole inner side is provided with internal thread, and described shoulder surface area is less than abaculus surface area, and described abaculus two ends are chute embedding shoulder.

The crossing rib of described abaculus and shoulder is the excessive face of arc.

Adopt design proposal of the present utility model, by rational design be make inserts and chute more identical, on the surface of contact of inserts and chute, globoidal structure is set, more smooth and easy in sliding process, be difficult for there is the problem of draw-in groove.

The utlity model has advantage reasonable in design, to be difficult for occurring draw-in groove.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Embodiment

Below in conjunction with drawings and Examples, the utility model is described in further detail.

The utility model comprises abaculus 2 and the shoulder 3 being connected as a single entity with abaculus 2, described shoulder 3 and the middle radially circular hole 4 that is provided with of abaculus 2, circular hole 4 inner sides are provided with internal thread 5, described shoulder 3 surface areas are less than abaculus 2 surface areas, described abaculus 2 two ends are chute embedding shoulder 1, described abaculus 2 is the excessive face 6 of arc with the crossing rib of shoulder 3, by rational design make inserts and chute more identical, on the surface of contact of inserts and chute, globoidal structure is set, more smooth and easy in sliding process, the difficult problem that draw-in groove occurs.

Claims (2)

1. a chute inserts, comprise abaculus and with the shoulder that abaculus is connected as a single entity, it is characterized in that being provided with radially circular hole in the middle of described shoulder and abaculus, circular hole inner side is provided with internal thread, described shoulder surface area is less than abaculus surface area, described abaculus two ends are chute embedding shoulder.

2. a kind of chute inserts according to claim 1, is characterized in that described abaculus and the crossing rib of shoulder are the excessive face of arc.
