Abstract

The utility model discloses a machine sewed and hand sewed ball, which comprises a ball body, wherein the ball body is formed by the orderly overlaying attachment of a first inner liner layer, a yarn winding layer, a second inner liner layer and an outer skin from inside to outside. Both the first inner liner layer and the second inner liner layer can be 1 mm to 3 mm thick. Both the first inner liner layer and the second inner liner layer can be 2 mm thick. The first inner liner layer and the second inner liner layer can be PVC layers or thermoplastic polyamido methylformate film layers. Because the structure of the ball body is modified, and the second inner liner layer additionally added, the elastic effect of the ball body is improved, the air tightness of the ball body is better and no slow air leakage can occur.

Description

A kind of sewing, ball sewed by hand

Technical field

The utility model relates to the ball of a kind of sewing or hand seam.

Background technology

Present the play sewing of usefulness or the ball of hand seam of people, general all by bladder layer, twine layer and outer leather sheath is formed, be provided with the reinforcement layer of cloth outside in the leather sheath, the spheroid of this structure, it is relatively poor to use elasticity, and air-tightness is not fine, in use for some time, tend to chronic gas leakage, have influence on people's result of use.

The utility model content

At the shortcoming that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of elasticity and the better sewing of air-tightness, ball sewed by hand.

The technical solution adopted in the utility model is: a kind of sewing, ball sewed by hand, it comprises spheroid, described spheroid from inside to outside successively by first bladder layer, twine layer, second bladder layer and crust cover in conjunction with forming.

The thickness of described first bladder layer and second bladder layer can be 1-3mm.

The thickness of the described bladder layer and second bladder layer can be 2mm.

Described first bladder layer and second bladder layer can be PVC layer or thermoplastic poly carbamic acid formicester rete or rubber liner layer.

Sewing of the present utility model, ball sewed by hand owing to change, have reduced the reinforcement layer of cloth on the structure of spheroid, increased by second bladder layer, spheroid is promoted on elastic effect greatly, and the air-tightness of spheroid are better, the phenomenon of chronic leakage can not occur.

The utility model is described in further detail below in conjunction with drawings and the specific embodiments.

Description of drawings

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

Fig. 2 is the cutaway view of the A-A direction of Fig. 1.

The specific embodiment

Shown in Fig. 1-2, sewing of the present utility model, ball sewed by hand, comprise spheroid 1, it is followed successively by first bladder layer 2 from inside to outside, twines layer 3, second bladder layer 4 and outer leather sheath 5 be combined intos, wherein the thickness of first bladder layer 2 and second bladder layer 4 is 1-3mm, or look required weight adjustment, material can be PVC layer or thermoplastic poly carbamic acid formicester rete or rubber liner layer.

Need by heating between layer of the present utility model and the layer, and the mode of increase glue realizes fitting together between layer and layer, or utilize material dissolving after the high temperature heating itself to combine to such an extent that feature combines.

Crust of the present utility model be enclosed within utilize under the state that does not need to strengthen patch behind sewing or the hand seam directly put into first bladder layer, twine layer, behind the inner bag that second bladder layer is integrally formed, can reduce being stressed of outer leather sheath, outer leather sheath circularity is because sewing that sewing or hand seam are caused or hand seam seam are inhomogeneous, can ensure circularity like this, increase air-tightness, extend working time and strengthen the elasticity of ball.

Claims

1, a kind of sewing, ball sewed by hand, it is characterized in that: it comprises spheroid, described spheroid from inside to outside successively by first bladder layer, twine layer, second bladder layer and crust noose and set up jointly.

2, sewing according to claim 1, ball sewed by hand is characterized in that: the thickness of described first bladder layer and second bladder layer is 1-3mm.

3, sewing according to claim 2, ball sewed by hand is characterized in that: the thickness of the described bladder layer and second bladder layer is 2mm.

4, according to claim 1 or 2 or 3 described sewings, ball sewed by hand, it is characterized in that: described first bladder layer and second bladder layer are PVC layer or thermoplastic poly carbamic acid formicester rete or rubber liner layer.
