Abstract
The utility model provides a detection device which can rapidly and accurately detect the gravity centre position of a badminton racket. The device comprises a detection table, a scale plate and a support shaft, wherein the support shaft parallel to the detection table is mounted above the detection table; the scale plate is installed on the detection table; and the length direction of the scale plate is perpendicular to the support shaft. During the detection, firstly, the detection table is placed horizontally, and the badminton racket is laid on the support shaft in such a manner that a racket rod of the badminton racket is perpendicular to the support shaft; secondly, the contact point of the badminton racket with the support shaft is adjusted until the badminton racket is in a horizontally balanced state, and such a contact point of the badminton racket with the support shaft is exactly the gravity centre position thereof; and thirdly, a user looks down at the detection table in such a manner that the visual line is perpendicular to the scale plate, and reads the scale on the scale plate corresponding to the bottom end of a grab handle of the badminton racket, which is the distance between the gravity centre position of the badminton racket and the bottom end of the grab handle thereof.
Description
Technical field
The utility model relates to a kind of pick-up unit that is used for measuring and analyzing the racket centre of gravity place, belong to sports equipment and detect field of measuring technique.
Background technology
The racket centre of gravity place is an important indicator estimating the racket performance, is of value to dissimilar professional athlete and shuttlecock amateurs such as singles, doubles are selected for use suitable racket.Reasonably the racket centre of gravity place will help to improve and optimizes the structural mechanical property of racket, make the racket manufacturing and the manufacturer that markets better satisfies the needs that professional athlete and amateur select racket for use.The present domestic instrument that detects the racket centre of gravity place fast and accurately that also do not have makes the detection of racket centre of gravity place not cause concern widely.
The utility model content
The purpose of this utility model provides a kind of pick-up unit that detects the racket centre of gravity place quickly and accurately.
This racket centre of gravity place pick-up unit comprises monitor station, scale, back shaft, and the back shaft that is parallel to monitor station is arranged on the monitor station top; Scale is installed on monitor station, and the length direction of scale is perpendicular to back shaft.
When using this device that the racket centre of gravity place is detected, earlier monitor station is in horizontality, racket is placed on the back shaft, the dabber of racket is perpendicular to back shaft.Adjust the contact point of racket and back shaft then, make racket be in the horizontal equilibrium state.At this moment, the contact point of racket and back shaft promptly is the centre of gravity place of racket, overlooks monitor station then, makes the sight line Vertical surveyors' staff, read the scale on the pairing scale in lever bottom of racket, can draw the distance of the centre of gravity place of racket to the lever bottom.
As improvement, back shaft is connected on the supporting seat on monitor station top, and on preferably back shaft was rotationally connected supporting seat, preferably back shaft was rotatably connected on the supporting seat by the bearing that is arranged on the supporting seat.Adopt bearing, can reduce the friction force between back shaft and the bearing seat, it is more flexible to make that back shaft rotates, and guarantees the accuracy of measurement result.
In the time of on back shaft is rotationally connected supporting seat, preferably be connected with the rotation hand wheel that is used to forward to back shaft on the back shaft.During detection, racket is positioned on the monitor station, lever is held on the monitor station, be held on the back shaft near the dabber that connects larynx, rotate rotation hand wheel with hand and drive the back shaft rotation, drive racket by back shaft and worm, on back shaft, be in the horizontal equilibrium state until racket; Read the pairing scale in lever bottom then, thereby apace the racket center of gravity is detected.
For above-mentioned arbitrary pick-up unit, be connected with on the monitor station and be used to regulate the screw of heightening that monitor station is in horizontality.Heighten screw by turn, can make monitor station be in horizontality fast.
For above-mentioned arbitrary pick-up unit, in order to judge accurately whether monitor station is in horizontality, monitor station is provided with the air-bubble level whether the monitoring monitor station is in horizontality.Preferably air-bubble level has two, is respectively applied on the pairwise orthogonal direction of monitoring monitor station in its plane whether be in horizontality.
Major advantage of the present utility model:
1, can measure the centre of gravity place of racket rapidly and accurately;
2, this apparatus structure is simple, and is with low cost, and stable performance, reliability height are swift to operate;
3, heighten screw and can determine the monitor station plane, air-bubble level then can detect this plane and make it as level reference, thereby reduces measuring error;
4, scale sense data apace makes that the use of instrument is very simple and easy, quick;
The utility model, to formulating the racket examination criteria, instruct professional athlete and amateur to select racket for use, and racket manufacturer and marketer have practical significance.

Embodiment
Referring to the racket centre of gravity place pick-up unit shown in Fig. 1-5, monitor station is composed of a fixed connection by four screws 8 by orthogonal transverse slat 31, stringer board 32.Stringer board 32 tops are fixed with bearing seat 2 respectively by pin 10, and bearing 9 is set in the bearing seat.Rotation hand wheel 6 is positioned at the outside of a bearing seat, and is connected with an end of back shaft by a radial location pin 12.Back shaft 7 two ends that are parallel to the monitor station upper surface also are connected with the inner ring of two bearings 9.Scale 5 is installed on transverse slat 31, and the length direction of scale is perpendicular to back shaft.The upper and lower side of stringer board 32 is attached with heightens screw 1, and the right-hand member of transverse slat is attached with gib screw 11.On transverse slat and stringer board, be respectively arranged with air-bubble level 4.Air-bubble level on the transverse slat is along arranging perpendicular to the axial direction of back shaft, and the air-bubble level on the stringer board is arranged along being parallel to the axial direction of back shaft.Heighten screw 1 for two by regulating on the stringer board, regulating monitor station, and come out by 4 monitorings of two air-bubble levels in the axial direction of back shaft and the horizontal situation on the direction axial perpendicular to back shaft.
The using method of this device:
1, this pick-up unit is put on the surface level.Adjusting is heightened screw and is observed in the air-bubble level vacuole equilibrium position that whether mediates, the equilibrium position if vacuole does not mediate, then continuing to heighten screw vacuole in two air-bubble levels equilibrium position that mediates, is level reference with assurance monitor station plane (monitor station upper surface);
2, racket is positioned on the pick-up unit; Lever is held on the transverse slat, is held on the back shaft near the dabber that connects larynx,
3, rotate rotation hand wheel with hand, racket is slowly advanced, on back shaft, be in the horizontal equilibrium state that is parallel to the monitor station upper surface until racket.Its center of gravity just is on the back shaft when racket will be in the horizontal equilibrium state, owing to the moment of the self gravitation reason that balances each other, makes racket be in the horizontal equilibrium state.
4, overlook monitor station, make the sight line Vertical surveyors' staff, read the pairing scale in racket lever bottom, can measure its centre of gravity place apace, conveniently choose racket and definite racket and select performance.
