Abstract
The utility model relates to a string-pulling device used for a racket stringing machine which can be used to arrange the strings of the sports apparatuses, such as tennis racket and battledore, etc. The utility model comprises a main board, a tension seat, a pulling-force indicator, a connecting piece and a sliding rail. The main board is glidingly arranged onto the sliding rail through the chain wheels with grooves to avoid the direct touching between the two parts and the wearing of parts can be reduced. A bearing is embedded into the chain wheel to make the gliding of the main board smooth. The connecting piece appears as an 'L'-shape with a big strength and the distortion is rare, which makes the force-measuring of the string-pulling device more accurate and has longer service life.
Description
Technical field
The utility model relates to a kind of racket threader, is meant a kind of anchoring of racket threader specifically.
Background technology
Racket threader is mainly used in the installation tennis racket, the string of a musical instrument of athletic equipments such as racket, generally form by frame bat device and anchoring, frame is clapped device and is used for fixing racquet frame, anchoring is used to strain the string of a musical instrument, existing anchoring as shown in Figure 1, comprise mainboard 1 ', tension seat 4 ', tension indicating device 2 ', brace 5 ' and slide rail 3 ', this mainboard 1 ' one side be pivoted a gear 11 ' and 3 pulleys 6 ', opposite side be provided with the rocking bar 14 of gear 11 ' be connected ', 2 pulleys 6 ' be positioned at slide rail 3 ' top wherein, another pulley 6 ' be positioned at slide rail 3 ' below, this slide rail be provided with a tooth row 31 ' with gear 11 ' engagement, these pulley 6 ' one sides be provided with a catch 61 ', be used to prevent mainboard 1 ' disengaging slide rail 3 '.Brace 5 ' as shown in Figure 6,90 ° of its middle part twist and warping, two ends are connected with tension indicating device with tension seat respectively.During use, rocking bar 14 ' driven gear 11 ' rotation, make mainboard 1 ' slide rail 3 ' on slippage, thereby the tension string of a musical instrument.Brace 5 ' the tension force of the string of a musical instrument is passed to the compression spring, tension seat are center of circle rotation with the pin, thus the string of a musical instrument can be tensioned to required poundage and braking slide rail 3 ' on.
Because mainboard 1 ' and catch 61 ' directly and slide rail 3 ' contact, and pulley 6 ' and slide rail 3 ' between be sliding friction, make mainboard 1 ' mobile having some setbacks, also wear and tear easily, influence the accuracy that the string of a musical instrument is strained.Because brace 5 ' the middle part bend distortion easily, cause the backguy poundage not enough.
The utility model content
The utility model provides a kind of anchoring of racket threader, and it is more smooth and easy that anchoring is slided, and reduces parts damages, thereby makes the backguy poundage more accurate.
The utility model adopts following technical scheme: the anchoring of this racket threader, comprise a mainboard, be fixedly arranged on the tension seat on mainboard top, be fixedly arranged on the tension indicating device at mainboard middle part, an a connecting piece and a slide rail, this mainboard one side be pivoted a gear and some sliding parts, and be provided with a rocking bar and be connected with this gear, described slide rail is provided with a tooth row and described gears engaged, described sliding part sleeves on this slide rail, described brace two ends are connected with tension indicating device with tension seat respectively, wherein, described sliding part is a pulley, the periphery of this pulley is provided with a groove along its circumferencial direction extension, and described slide rail is provided with the raised line with described groove fit; Described brace is L-shaped, is made up of two orthogonal support plates, and described tension seat and tension indicating device are connected on two support plates.
Described bottom portion of groove can be circular arc, and correspondingly, described raised line top is circular arc.
Described mainboard sets firmly one " U " shape liner plate, and described gear two ends are hubbed at respectively on mainboard and the liner plate, and the pivoted hole edge of described liner plate is convexly equipped with an annular boss.Can be embedded a bearing in the pivoted hole of this liner plate and mainboard, it is more smooth and easy that gear is rotated.
Can be embedded a bearing in the pulley, this bearing is connected on the mainboard.Aforesaid bearing can be ball bearing or other known bearings.
By above-mentioned description to the utility model structure as can be known, pulley of the present utility model is provided with groove mainboard and slide rail is kept apart certain distance, has avoided the friction of the two, reduces component wear, is embedded bearing in the pulley, and just the mainboard slippage is more smooth and easy.Adopt L-shaped brace, intensity increases, and is not yielding, makes the anchoring dynamometry more accurate, longer service life.

The specific embodiment
Describe the specific embodiment of the present utility model with reference to the accompanying drawings in detail.
The anchoring of this racket threader is as shown in Figure 2: tension seat 4 is fixedly arranged on mainboard 1 top, and tension indicating device 2 is fixedly arranged on mainboard 1 middle part, and brace 5 is shown in Fig. 7-9, and its two ends are connected on tension seat 4 and the tension indicating device 2.Pulley 6 is articulated on the mainboard 1, is provided with 3 altogether, is divided into slide rail 3 both sides.As shown in Figure 3-4, pulley 6 is provided with groove 62, and the raised line on the slide rail 3 just in time is positioned at groove 62, also is provided with a dead eye 63 in the pulley 6, is embedded a ball bearing in it.The structure of groove 62 also can be as shown in Figure 5, and its bottom is circular arc, the also corresponding circular arc that is of the shape of raised line on the slide rail 3.Set firmly a liner plate 12 on the mainboard 1, as shown in figure 10, liner plate 12 is " U " shape, gear 11 two ends are articulated in respectively on mainboard 1 and the liner plate 12, and the pivoted hole edge of liner plate 12 is provided with boss 13, and the gear 6 and the contact area of liner plate 12 are increased, gear 6 is difficult for loosening, can increase the service life.
Above-mentioned is the specific embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that the utility model is carried out the change of unsubstantiality, all belongs to the behavior of invading the utility model protection domain.
