Description

  The present invention relates to a racket gutting machine, and more particularly to a stereotactic structure of a racket frame fixing device for a racket gutting machine.

  Ball game equipment including an annular frame, such as a tennis racket or a badminton racket, stretches a gut with elasticity in the racket frame to form a reticulated striking surface. In order to effectively hit the ball and to allow the player to control the flight direction of the sphere after the ball is hit, the ball hitting surface presents an appropriate tension. The tension of the ball striking surface is determined by the tensile stress value formed by the stretching action that the gut receives when the ball striking surface is formed by stretching the gut. In order to facilitate the work of stretching the gut and to make the numerical value of the tensile stress accurate, the gut tensioning work is generally performed using a gut stretcher.

  Before performing a gut tensioning operation with a gut tensioner, first, a pair of frame fixtures provided in the gut tensioner are used to fix and position the racket frame. As shown in FIGS. 1 and 2, the conventional structure of the frame fixing device includes a guide plate 2, a fixing device 3, and a fixing bolt 5 that are fixedly installed on the top surface of the base plate 1 of the gut tensioner. The guide plate 2 is installed by piercing a rectangular guide tank 202 along the axial direction. The columnar base 4 of the fixing device 3 contacts the apex edge of the conductive plate 2. The bottom portion of the base 4 has a hollow shape and includes a bottom plate 402. At the bottom end of the bottom plate 402, two fixed columns 404 are installed in a protruding shape, and the fixed columns 404 enter the guide tank 202 in a movable manner. One end of the fixing bolt 5 is provided with a plastic rotary head 502, and the other end passes through the guide tank 202 from the bottom end of the base plate 1 and is screwed into and connected to the bottom plate 402. The fixing bolt 5 is provided with a washer 504 between the rotary head 502 and the base plate 1. Thereby, if the fixing bolt 5 is turned and loosened, the base 4 can be pushed and reciprocated along the guiding tank 202. After the base 4 is moved to the racket to be clamped and positioned, the fixing bolt 5 is turned and tightened. Thus, the fixing devices 3 can be localized, and each fixing device 3 can be fixed to the annular frame of the racket.

  Because different types of rackets have different frame sizes and formats, when each fixator 3 clamps and fixes the frame, the distance between each fixer 2 must be different according to the different size frame. There are many. Therefore, since it fixes according to the racket of various types and sizes, it cannot be said that each fixer 3 can be localized only at a single distance. Further, when not in use, the space occupied by the gutting machine is reduced, so that after the gutting operation is completed, the respective fixing devices 3 are often moved closer to each other and positioned. However, in this case, every time the fixing device 3 is moved and positioned, first, the fixing bolt 5 is turned and loosened to release the fixed state of the fixing device 3 and when the fixing device 3 is moved to a required position. The fixing bolt 5 must be turned and tightened to restore the stereotaxic state to the fixing device 3, and the operation is very troublesome. The present invention has been made in view of the above-mentioned drawbacks of the stereotactic structure of a racket frame fixing device of a conventional racket gutting machine.

  The problem to be solved by the present invention is that a newly-developed swing-type claw component makes it possible to support a rack equipped with a ratchet, and to quickly release and recover the position of the base plate of the fixing device's gut tensioner.

  As shown in FIGS. 3, 4, and 5, the embodiment of the stereotactic structure of the racket frame fixing device of the racking machine of the present invention includes a rack 10, a guide plate 20, a claw part 30, an operation part 40, and a spring 50. . The rack 10 is installed by being fitted to the base plate 90 of the gut tensioner. A plurality of ratchets 12 are installed in a row on the top surface of the rack 10. The guide plate 20 is installed by being fitted to the top of the base plate 90. The bottom surface of the base plate 90 corresponds to the guide plate 20 and the receiving plate 60 is installed. The rack 10 is installed on the receiving plate 60 and positioned. Two guide tanks 22 are installed in the guide plate 20 in a penetrating manner. Each guiding tank 22 is adjacent to both sides of the rack 10, and each guiding tank 22 and the rack 10 are parallel to each other. The receiving plate 60 is provided with two rectangular fitting tanks 64 in a penetrating manner, and is adjacent to each guiding tank 22. The columnar body 81 of the fixing device 80 is installed at the apex of the base plate 90. Two rectangular slide blocks 82 are installed on the bottom surface of the main body 81. Each slide block 82 is movably fitted to each guiding tank 22 and each fitting tank 64. Thereby, the fixing device 80 is guided and reciprocated along the direction of the introduction tank 22. A connection base 83 is installed on the bottom surface of the receiving plate 60, and each slide block 82 is positioned on this.

  A housing chamber 85 is formed inside the main body 81 and is adjacent to the rack 10. The claw component 30 is movably installed in the accommodation chamber 85. A shaft bar 32 is provided in a penetrating manner at the central portion of the claw component 30. Both ends of the shaft rod 32 are installed through the inner walls on both sides of the storage chamber 85, whereby the claw component 30 performs a reciprocating swing operation around the shaft rod 32 in the storage chamber 85. The bottom end of the claw component 30 extends toward the rack 10 to form a unidirectional fixation with the ratchet 12 of the rack 10, thereby localizing the fixture 80.

  The operation component 40 is movably installed in the storage chamber 85. Since the operation component 40 is a curved key-shaped plate body, one end of the operation component 40 is a lock portion 41 and the opposite end is a localization portion 42. The lock portion 41 and the localization portion 42 are opposed to each other, and the operation component 40 is an operation portion 43 at a curved middle portion between the lock portion 41 and the localization portion 42. The operation unit 43 protrudes outside the main body 81. The operating component 40 is provided with a pivot 44 in the localization portion 42. Both ends of the pivot 44 are movably connected to the main body 81. The middle part of the operation component 40 is recessed in one side to form a long tank 45. A position limiting rod 46 is movably inserted into the long tank 45. One end of the position limiting rod 46 is connected to the main body 81. Accordingly, the operation component 40 performs a swing operation with the pivot 44 as an axis, and the position limiting rod 46 limits the swing range of the operation component 40 in response to this. The apex end of the claw part 30 extends between the lock part 41 and the localization part 42, and the claw part 30 and the bottom surface of the lock part 41 are adjacent to each other. Thereby, the lock | rock part 41 stops the swing of the nail | claw part 30, and cancels | releases the unidirectional fixation of the nail | claw part 30 and the rack 10 in this way. Thereby, the convenience of operation which moves and fixes the fixing device 80 can be improved.

  The spring 50 is a spiral spring installed in the storage chamber 85. One end of the spring 50 is connected to the main body 81, and the opposite end is connected to the claw component 30. One end of the spring 50 is fitted to the stereotaxic pin 52. The localization pin 52 is screwed into and connected to the main body 81, and one end of the spring 50 is in contact with the inner wall of the accommodation chamber 85. The opposite end of the spring 50 is movably fitted to the claw component 30. Thus, the spring 50 is localized, and the spring 50 provides elasticity to the claw component 30, so that the claw component 30 can hold unidirectional fixing to the rack 10.

  As shown in FIGS. 4 to 6, when the fixing device 80 of the gut tensioner is adjusted so that the annular frame (not shown) of the racket is clamped by the fixing device 80, first, the two fixing devices 80 in pairs are paired. Are moved toward both ends of the base plate 90 of the gut tensioner. As a result, the distance between the two fixing devices 80 increases. At this time, since the apex of the rack 10 constitutes the unidirectional ratchet 12, the fixing device 80 is pushed directly outward to move. Since the elasticity of the spring 50 forms a pushing action against the claw component 30, the claw component 30 is moved by being pushed outward in the fixing device 80. The contact state is maintained, and the ratchet 12 is fitted one by one in order. When the fixing device 80 is moved to the required position and is positioned, the fixing device 80 is positioned by the relative configuration between the claw component 30 and the ratchet 12, and does not move arbitrarily toward the center of the base plate 90. Thereby, the fixing operation | work of a racket frame can be performed. When the gut tensioning operation is completed, the frame is removed, and the fixing device 80 is moved toward the center of the base plate 1. Thus, when the gutting machine is stored when not in use, as shown in FIG. 6, the operation unit 43 is pushed toward the main body 81, and thus the operation component 40 is rotated in the clockwise direction with the pivot 44 as an axis. Swing to. As a result, the lock portion 41 pushes the apex end of the claw component 30 downward, and thus the claw component 30 swings in the counterclockwise direction around the shaft bar 32 to fix the claw component 30 and the rack 10 in one direction. Is released. In this way, each fixing device 80 can be pushed and moved inward. As a result, when each fixing device 80 is moved to the required position in the center direction of the base plate 90 and is positioned, the control on the operation unit 43 is released, and the claw component 30 is restored by the elasticity of the spring 50, The unidirectional fixing between the claw component 30 and the rack 10 is restored, and thus the fixing device 80 is localized.

  As described above, according to the present invention, when the fixer 80 is to be moved outward by the newly developed configuration, it is not necessary to release the fixer 80 first, and the fixer 80 is directly moved to the outside. All you need to do is push, move and pan. On the other hand, when the fixing device 80 is to be moved inward, the localization of the fixing device 80 can be released by pressing the operation component 40, and thus the fixing device 80 can be easily moved inward. it can. That is, the movement and localization operation of the fixing device 80 can be performed easily and quickly, and the convenience of use can be enhanced.
