Abstract
The utility model discloses a pipe fitting structure of a sport equipment. At least two continuous convex ribs are distributed on the external surface of a pipe fitting in an interlaced and inclined manner to form a reinforcing net on the external surface of the pipe fitting. The external surface of the pipe fitting structure is provided with continuous inclined convex ribs which are at included angles to the pipe fitting along the axial direction, and the convex ribs reinforces the structure strength of the pipe fitting. The included angles between the convex ribs and the pipe fitting along the axial direction ensure the lateral bearing capacity of the pipe fitting. A plurality of convex ribs form an interlaced network structure, which further ensures the bearing capacity of the pipe fitting in all directions, and improves the anti-torsion capability of the pipe fitting. The pipe fitting structure overcomes the defects of a pipe fitting which is high in rigidity and low in flexibility, and improves the use safety of the pipe fitting.
Description
Technical field
The utility model is about a kind of fitting structure, refers to a kind of sports equipment fitting structure with anti-twisting property especially.
Background technique
Continuous development along with materials science, the material of many sports equipments is used and is also being constantly brought forth new ideas, for example: polymer composite fiber material (being called for short " multiple material ") is because having the strong characteristics of rigidity in light weight, the tubing that is widely used in the motion device is made, in the oar and mast as club, vehicle frame or even sailing boat.Many ball game must cooperate club or racket, for example bandy, hockey, golf ball, tennis or shuttlecock etc.And existing club or racket, what have makes for timber, and what have is the full-metallic moulding, and what have then is full equipment structure again.Yet various clubs or racket all exist outside the deficiency:
One, for wooden, then Heavy Weight, and waste timber, not environmental protection, long-term use is easy moisture absorption gas also, and influence usability.
Two, for full-metallic, though the external form moulding is easy, wall thickness is control easily also, so easily produce, has the cost of material height, or yielding, the problem of insufficient strength.
Certainly, these two kinds of deficiencies not office in the oar of vehicle frame and sailing boat and mast, have above-mentioned deficiency in club or racket equally.
And adopt multiple material just can remedy above-mentioned deficiency, though but its intensity of section product structure is enough again, and flexible not good, be that twisting resistance is not enough, for very fast and stressed some the big sports equipments of movement velocity, the anxiety of equipment pipe fitting fracture appears in the not good meeting of this twisting resistance, causes potential safety hazard.
Also there is the not good problem of twisting resistance in golf clubs for full-metallic is made.
The model utility content
The purpose of this utility model provides that a kind of can to increase pipe fitting flexible, improves the sports equipment fitting structure of its twisting resistance.
For achieving the above object, solution of the present utility model is:
A kind of sports equipment fitting structure, wherein: the outer surface at pipe fitting is provided with at least two continuous convex tendons, and each convex tendon is being arranged on the pipe fitting of staggered inclination, to form the reinforcement net at outer surface of pipe fittings.
The axial angle of inclination of the relative pipe fitting of described each convex tendon is that 10 degree are to 60 degree.
The axial angle of inclination of the relative pipe fitting of described each convex tendon is 45 degree.
Described each convex tendon and pipe fitting are one-body molded.
Described each convex tendon is incorporated on the outer surface of pipe fitting at secondary behind the formation of tubes.
Described pipe fitting is polymer composite.
Described pipe fitting is metallic material, and convex tendon is polymer composite.
After adopting such scheme, the continuous tilt convex tendon that the utility model axially forms angle by outer surface setting and pipe fitting at the sports equipment pipe fitting, convex tendon forms strengthening action to the structural strength of pipe fitting; Axially form the setting of angle in addition with pipe fitting, guaranteed the ability of pipe fitting lateral force again; The staggered reticular structure that has many convex tendons to form again, further guaranteed the stressed ability of pipe fitting all directions, and then realized improving the flexible and antitorque ability of pipe fitting, remedy the good and flexible weak defective of pipe fitting rigidity, improve the Security that the sports equipment pipe fitting uses.

Embodiment
Explain mode of execution of the present utility model below in conjunction with accompanying drawing:
As shown in Figures 1 to 4, the utility model has disclosed a kind of sports equipment fitting structure, this pipe fitting is to be made by polymer composite or metallic material, its key is: the outer surface at pipe fitting 1 is distributed with at least two continuous convex tendons 2, each convex tendon 2 is being arranged on the pipe fitting 1 of staggered inclination, forming reinforcement net (seeing shown in Figure 2) at pipe fitting 1 outer surface, each convex tendon 2 relative pipe fittings 1 axial angle of inclination be 10 degree to 60 degree, spending tilt angle with 45 is the best.
Racket structure as shown in Figure 1, this reinforcement net is on the dabber 5 that is arranged between frame 3 and the lever 4, because dabber 5 need bear the impact force of the different direction that transmits frame 3 batting backs, the reinforcement net that is formed by inclination convex tendon 2 that arranges at dabber 5, can effectively improve the anti-twisting property of dabber 5, increase the flexible of dabber 5.Certainly, this reinforcement net can be covered with whole dabber 5, also can arrange in the part of dabber 5.
Hockey stick structure shown in Fig. 2,2A, this reinforcement net is to be arranged on the surface of club 6 pipe fittings, it can be distributed on the whole club 6, also can only be arranged at the part, as be positioned at the forward position (namely being subjected to the position of torsion maximum) of club 6, so can effectively increase the anti-twisting property of club 6.
Tennis racket structure as shown in Figure 3, this reinforcement net can be arranged on the frame 7 of racket, also can be arranged on triangle part 8 or lever 9 places of racket, or be provided with the reinforcement net that is formed by inclination convex tendon 2 at whole racket, thus the anti-twisting property of strengthening net racket.
Body frame structure for automotive as shown in Figure 4 again arranges above-mentioned reinforcement net at each pipe fitting 10 or the pipe fitting of one of them of vehicle frame, also can improve the anti-twisting property of bicycle frame pipe 10 equally.
This reinforcement net is applicable to that also various needs such as the mast of golf clubs or sailing boat and quant bear on the pipe fitting of torsion.The convex tendon 2 of this inclination can go out when pipe fitting 1 moulding in once-through, also can be after pipe fitting 1 moulding, convex tendon 2 secondary again is incorporated on the outer surface of pipe fitting 1, after can adopting Ti metal to make as golf clubs, be combined with the convex tendon of composite material again at its outer surface, can under the condition that guarantees the golf clubs rigidity, improve its anti-twisting property greatly, extend the big life-span of use of club.
Certainly, the sports equipment pipe fitting can form the continuous groove that is staggered inclination on its outer surface after increasing its caliber, can realize above-mentioned effect equally.
In sum, the inclination convex tendon 2 that the utility model axially forms angle by outer surface setting and pipe fitting 1 at sports equipment pipe fitting 1, the structural strength of 2 pairs of pipe fittings 1 of convex tendon forms strengthening action; Axially form the setting of angle in addition with pipe fitting 1, guaranteed the ability of pipe fitting 1 lateral force again; The staggered reticular structure that has many convex tendons 2 to form again, further guaranteed the stressed ability of pipe fitting 1 all directions, and then realize to improve flexible and the antitorque ability of pipe fitting 1, and remedy the good and flexible weak defective of pipe fitting rigidity, improve the Security of sports equipment pipe fitting use.
