Abstract

The utility model is a structure for pool cue ferrule. The structure provides a ferrule body, the ferrule body having a side wall and an end wall, the side wall and end wall provided with an inner surface and an outer surface respectively. A chamber is formed by all the inner surfaces. A tip attached on the outer surface of the ferrule body. A tenon is provided on the tip of pool cue. An intermediate component is provided between the ferrule body and the tenon to connect with the two components together firmly.

Description

Replaceable billiard stick ferrule arrangement

Technical field

The utility model is relevant with billiard stick, particularly about a kind of replaceable billiard stick ferrule arrangement.

Background technology

The U.S. the 6th, 890, No. 246 the patent case has disclosed a kind of replaceable billiard stick ferrule arrangement, with so that amateurish billiards person when on billiard table, carrying out billiards, can have the preferable driving head of situation or need not to repair driving head.This ferrule arrangement has a lasso body, and this body is socketed on the batting end of a billiard stick by a room, then lays an annular groove in order to embed an elastic washer in this batting end in addition, holds so that this lasso body is socketed on this batting in interchangeable mode.

This kind design is used unsatisfactory actually, because it only can just can produce the effect of fluid-tight engagement at the position with packing ring, in other words, after this lasso body is socketed on billiard stick batting end, except position with packing ring, still there is the gap at other position, and therefore, this lasso body can rock and makes billiards person's ability of controlling the ball be affected at square stance.

The utility model content

So main purpose of the present utility model is promptly providing a kind of replaceable billiard stick ferrule arrangement, it can make lasso simple and easy and firmly be socketed on billiard stick batting end.

A kind of replaceable billiard stick ferrule arrangement of the present utility model is characterized in that, includes:

The one elongated tubular lasso body made from hard material, this lasso body has a sidewall and an end wall, and this sidewall and this end wall have an outer surface and an inner surface respectively, and respectively this inner surface defines a room;

One driving head attaches to the outer surface of this lasso body end wall;

One tenon is located at the batting end of billiard stick; And

One intermediate piece is laid in this lasso body and is used for making this between this tenon the two can firmly connect together.

Wherein this intermediate piece includes posterior limiting, and it attaches on the surface of this tenon.

Wherein this elastic layer is made with plastic material.

Wherein this tenon has a side surface and a upper surface.

Wherein this intermediate piece includes posterior limiting, and it is attached at the side surface of this tenon.

Wherein this intermediate piece includes posterior limiting, and it is attached at the side surface and the upper surface of this tenon.

The beneficial effects of the utility model are:

Replaceable billiard stick ferrule arrangement of the present utility model, it can make lasso simple and easy and firmly be socketed on billiard stick batting end.

Description of drawings

Below enumerate a preferred embodiment and conjunction with figs. the utility model is described further, wherein:

Fig. 1 is the lateral plan of the utility model one preferred embodiment;

Fig. 2 is along the cutaway view on the 2-2 direction among Fig. 1;

Fig. 3 is the axial decomposition view of embodiment as shown in Figure 2; And

Fig. 4 is along the cutaway view on the 4-4 direction among Fig. 1.

The specific embodiment

See also each accompanying drawing, wherein the wooden billiard stick shown in the figure number 10 for implementing according to the utility model.Billiard stick 10 has a major axis section 12, and the one end is provided with a tenon 14, one lasso bodies 20 and is socketed on the tenon 14.

Lasso body 20 is a long tube body made from hard material, has a sidewall 22 and an end wall 24.Sidewall 22 has an outer surface 26 and an inner surface 28; End wall 24 has an outer surface 30 and an inner surface 32 equally.Inner surface 28 and 32 has defined a room 40 with opening 42.During combination, tenon 14 is in opening 42 is inserted into room 40.

One driving head 50 (tip) is attached to the outer surface 30 of end wall 24.One intermediate piece 60 is one to make and the elastic layer of tool predetermined thickness with plastic material in present embodiment, and it is side surface 16 and upper surface 18 that cover invests tenon 14.Certainly, elastic layer 60 also can only be located at the side surface 18 of tenon 14.When reality is made, can make the internal diameter of room 40 be slightly smaller than total external diameter after elastic layer 60 is attached at tenon 14, with so that lasso body 20 has more closely with 14 of tenons engages.

Design as can be known as the aforementioned, owing to be gripped with elastic layer 60 between lasso body 20 and the tenon 14, therefore, lasso body 20 not only can be socketed on very closely on the tenon 14 but also also and can very simply it be taken off, and preceding shortcoming of taking off existing ferrule arrangement promptly can not take place.

Claims
