Abstract

The utility model discloses a strengthening type hollow fiber pipe comprising a fiber pipe body. The fiber pipe body is hollow and provided with a through hole. A plurality of strengthening ribs are integrally formed on the inner walls of the two ends of the through hole in a protruding mode. Each strengthening rib axially extends in the direction towards the middle of the fiber pipe body. The height of each strengthening rib decreases from the outer end to the inner end. Due to the facts that the strengthening ribs are integrally formed on the inner walls of the two ends of the through hole in the protruding mode, and the height of each strengthening rib decreases from the outer end to the inner end, the strength of the two ends of the hollow fiber pipe is improved greatly, the possibility of damage to a ball arm or a racket or the like is reduced, the service life is prolonged, materials are reduced, use cost is saved, meanwhile, a shock absorption effect is improved effectively under the situation of reducing the materials, and a user can get a better feeling in hitting a ball.

A kind of enhancement mode hollow fiber conduit, include fiber body, this fiber body hollow and be formed with through hole, the two ends inwall of this through hole is all one-body molded convexes with a plurality of stiffening ribs, each stiffening rib all extends axially towards the middle part of fiber body direction, and the height of each stiffening rib reduces to the inner by outer end.

As a kind of preferred version, the external diameter size of described fiber body evenly, the aperture of two outer ends of this fiber body all reduces inwardly and in the inside, two ends of fiber body, forms respectively taper cavity, and the inwall of each taper cavity is all one-body molded convexes with a plurality of aforementioned stiffening ribs.

As a kind of preferred version, the outer wall of described fiber body is cylindrical.

As a kind of preferred version, described fiber body includes first paragraph body, second segment body and the 3rd section of body of one-body molded connection successively, in this first paragraph body and the 3rd section of body, be all formed with aforementioned taper cavity, the wall thickness of this first paragraph body is increased to the inner by the outer end of first paragraph body, the wall thickness of the 3rd section of body is increased to the inner by the outer end of the 3rd section of body, and the wall thickness of this second segment body evenly and compared with the wall thickness of the wall thickness of first paragraph body, the 3rd section of body wants large.

As a kind of preferred version, the length of described first paragraph body and the 3rd section of body equal in length.

As a kind of preferred version, in described second segment body, be formed with column cavity, this column cavity is communicated with between two taper cavitys and forms aforementioned through-hole.

As a kind of preferred version, described a plurality of stiffening ribs are uniformly at intervals on corresponding taper cavity inner wall.

The utility model compared with prior art has obvious advantage and beneficial effect, particularly, and as shown from the above technical solution:

One, by the two ends inwall in through hole is all one-body molded, convex with a plurality of stiffening ribs, utilize the height of each stiffening rib to reduce to the inner by outer end, greatly to have strengthened the intensity at hollow fiber conduit two ends, reduce the possibility that club or racket etc. damage, extended its working life, reduced material, saved user cost, in the situation that reducing materials, effectively improve damping effect simultaneously, contributed to user to obtain better touch.

Two, utilize the external diameter size of fiber body even, coordinate the aperture of two outer ends of fiber body all reduce and in the inside, two ends of fiber body, form respectively taper cavity inwardly simultaneously, so, realized the thick variation of fibre pipe body wall, make the interior thickness of fiber body larger, structural strength is higher.

For more clearly setting forth structure characteristic of the present utility model and effect, below in conjunction with accompanying drawing and specific embodiment, the utility model is elaborated.

Embodiment

Please refer to shown in Fig. 1 and Fig. 2, the concrete structure that it has demonstrated the preferred embodiment of the utility model, includes fiber body 10.

As shown in Figure 1, this fiber body 10 hollows and be formed with through hole 101, the two ends inwall of this through hole 101 is all one-body molded convexes with a plurality of stiffening ribs 102, and each stiffening rib 102 all extends axially towards the middle part of fiber body 10 direction, and the height H of each stiffening rib 102 reduces to the inner by outer end.

In the present embodiment, the external diameter size of this fiber body 10 evenly, the aperture of two outer ends of this fiber body 10 all reduces inwardly and in the inside, two ends of fiber body 10, forms respectively taper cavity 1011, the inwall of each taper cavity 1011 is all one-body molded convexes with a plurality of aforementioned stiffening ribs 102, and the plurality of stiffening rib 102 is uniformly at intervals on corresponding taper cavity 1011 inwalls (as shown in Figure 2).
