Abstract
The utility model discloses an improving structure of racket frame, relating to the carbon fiber tennis racket. The head frame which is of approximate ellipse is a hollow tube; the head frame is provided with an outer wall, an inner wall and threading holes penetrating through the outer wall and the inner wall; the inner wall of the racket forms concave and convex shape; the inner wall of the head racket is provided with a plurality of groove blocks of approximate ellipse or rectangle, the positions of two adjacent threading holes which are corresponded with each groove block and the bottom of the groove block are cut as perforated opening or penetrated out two threading holes. The above structure can balance and absorb the overlong part of the inner wall after the tube strip bending ,thereby solving the problem of the puckering of the inner wall, so the inner wall assumes smooth concave and convex shape without puckering after the tube strip is made into racket, and the problem that the intensity of the racket at the puckering section is greatly reduced because of the puckering can be solved.
Description
Technical field
The utility model relates to a kind of carbon fibre web racket.
Technical background
The frame of general carbon fiber racket, its structure are made up of a frame 1 of approximate ellipsoidal and the moon eyebrow 2 on oval base as shown in Figure 1.When frame is made, be to roll into hollow straight tube-like behind the material textile board lamination again by carbon fiber, this straight tube-like thing is commonly called as the pipe range bar.Be built-in with a nylon tracheae at the pipe range bar.Can crooked plastotype before the pipe range bar is uncured.Frame of racket is exactly a frame that the pipe range bar is become an approximate ellipsoidal in the pre-type of uncured front curve; Other gets a moon eyebrow section, and its two ends difference adapter frame is also used the carbon fiber tape winding reinforcing; Pre-type becomes the frame shape, this pre-type frame is inserted heating in the mould, pressurization again, and making it curing molding is the one frame.A frame cross section of this frame is to be provided with the hollow pipe that several run through the line hole of a frame outer wall, inwall; Open and to be located at a netting twine of frame outer wall and to pass each line hole according to this, in the zone that the inwall ring encloses, wear the wire side that fork is woven into batting.Wherein, when the pipe range bar was bent pre-type by straight tube-like, a frame inwall often had fold to produce.This be because crooked back madial wall long due to, and most fold still exist behind the curing molding, fold place intensity reduces, and very easily causes slight crack or fracture.How to eliminate fold, the quality that improves racket becomes the direction of dealer's research and development.
The utility model content
The purpose of this utility model is to provide a kind of structure-improved of frame of racket, to eliminate the fold of frame inwall, improves the quality of racket.
In order to reach above-mentioned purpose, solution of the present utility model is:
The structure-improved of frame of racket, a frame cross section of approximate ellipsoidal is a hollow pipe; Frame has outer wall, inwall and runs through the line hole of its outer wall, inwall; Inwall at frame forms concavo-convex; The inwall of frame is provided with the recessed block of a plurality of approximate ellipsoidals or rectangle, the duct that two cut one-tenth in line hole site and bottom that each recessed block is corresponding adjacent connect or get out two line holes.
Each recessed block of the corresponding inwall of the outer wall of described frame respectively is provided with a recessed block, constitutes one group of recessed block; The duct that the cut one-tenth in the bottom of the recessed block of each of outer wall connects.
The teething ring that similar shape matches is installed in the duct of the outer wall of described frame and every group of correspondence of inwall, and bottom and inwall that the outward flange at this teething ring middle part is stuck in the recessed block of outer wall are recessed between the bottom of block.
In the preferred construction: the recessed block of described each group be arranged on a frame the and arranged on left and right sides middle part or be arranged on the top of a frame or be arranged on the and arranged on left and right sides middle part and the top of a frame.
The outer wall of described frame and the both sides, front and back between the inwall form concavo-convex ripple.
The recessed block of each of described frame inboard is arranged in the recessed figure line.
Perhaps: the recessed block of each of described frame inboard is arranged in the protruding figure line.
After adopting said structure, the utility model forms concavo-convex at the inwall of frame, the concavo-convex structure of the recessed block formation of a plurality of approximate ellipsoidals or rectangle particularly is set at the inwall of a frame, but balance, the long part of the rectangular crooked back inwall of absorption tube, thereby solve the problem of inwall fold, after making the bending of pipe range bar make frame, it is smooth concavo-convex and do not have fold that inwall is, and solves because of fold to make racket in this fold section part intensity problem that declines to a great extent.Establish corresponding recessed block and take into account two adjacent line hole sites at outer wall, can make being provided with rationally of recessed block position on the one hand, frame is increased because of concavo-convex structure second moment, racket intensity improves, and the racket product quality improves.Become the duct of perforation can strengthen the visual effect of frame the outer wall of a frame and the Bottoming of each recessed block of inwall.The teething ring that similar shape matches is installed in each duct, can be reduced the wearing and tearing to netting twine on the one hand, the windage of frame when brandishing reduced, the feel of swinging the bat is more comfortable.Form concavo-convex ripple in the outer wall of a frame and the both sides, front and back between the inwall and cooperate, gain in strength and can make the racket outward appearance more active with each recessed block.A recessed block of each of frame inboard is arranged in the recessed figure line, in the perhaps protruding figure line; Can strengthen the effect of preventing wrinkle.In sum, the utility model can increase the value of racket.
