Abstract
The utility model discloses an automatic net drawing device. The automatic net drawing device comprises an upper end cover, a spring, a wheeled hollow shaft, a shaft sleeve, a connecting sleeve, a grooved sleeve, a lower end cover and a rope. The shaft sleeve sleeves the wheeled hollow shaft and the inner hole of the connecting sleeve sleeves the wheeled hollow shaft. One end of the connecting sleeve is connected with the upper end cover by use of threads, while the other end of the connecting sleeve is connected with one end of the grooved sleeve by use of threads. One end of the spring is fixed on a projection of the upper end cover, while the other end of the spring is fixed on a projection of the wheeled hollow shaft. The lower end cover is connected with the other end of the grooved sleeve by use of threads. One end of the rope is fixed on the wheel of the wheeled hollow shaft, while the other end of the rope is arranged outside the device after passing through a small hole formed in the upper end cover. One end, passing through the grooved sleeve, of a net is fixed on the wheeled hollow shaft, while the other end of the net is fixed on an external hollow shaft located on the device. The automatic net drawing device is capable of ensuring tensioning of the net, and is fast and convenient for drawing the net, and also advantageous for storing the net.
Description
Technical field
The utility model relates to a kind of sports goods, especially, relates to a kind of automatic receipts net of realizing table tennis net, and can guarantee in use the device of net in tensioning state.
Background technology
While using table tennis net at present, network capacity is the loosening sagging tensioning that can not guarantee net easily, impact match; And all need while collecting table tennis net manually to receive, but also not ideal difficult preservation of effect.
Summary of the invention
While using table tennis net in order to overcome, net loosening sagging, receives that net is inconvenient, effect is bad, receives the defect that is difficult for storage after net, and the utility model provides a kind of automatic receipts net arrangement.
The technical scheme that the utility model solves its technical problem employing is:
The utility model comprises upper end end cap, clockwork spring, contains wheel hollow shaft, axle sleeve, adapter sleeve, slotted sleeve, lower end end cap and rope.Described axle sleeve is enclosed within containing in wheel hollow shaft, and adapter sleeve inner hole sleeve is containing in wheel hollow shaft.Adapter sleeve one end is connected with upper end end cap by screw thread, and the other end is connected with slotted sleeve one end by screw thread.Clockwork spring one end is fixed in the projection of upper end end cap, and the other end is fixed in the projection containing wheel hollow shaft.Lower end end cap is connected with the slotted sleeve other end by screw thread.Rope one end is fixed on the wheel containing wheel hollow shaft, and the other end is placed in device outside through the aperture of upper end end cap.Net is fixed on containing in wheel hollow shaft through slotted sleeve one end, and the other end is fixed on the hollow outer shaft that is positioned at device.
The beneficial effects of the utility model are, while using table tennis net, guarantee the tensioning of net, efficient and convenient while receiving net, and are beneficial to the preservation of net.
