Description

Table tennis racket with auxiliary force structure

Technical Field

The utility model relates to the technical field of sports equipment, in particular to a table tennis racket with an auxiliary force-generating structure.

Background Art

Table tennis originated in the UK. The name "ping pong" originated in 1900 because it was named "ping pong" because of the sound it made when hit. A table tennis racket consists of three parts: base, rubber and sponge. The reasonable combination of the three determines the quality of a racket.

The existing table tennis racket is held in a straight grip or a horizontal grip when in use, and the table tennis ball is hit according to its movement trajectory and landing point, so that it rebounds over the net and hits the table on the opponent's side.

The above-mentioned prior art solutions have the following defects: since the grip handle of the table tennis racket is smooth and has no material, the friction between the table tennis racket and the palm during use depends on the grip strength. When a hand injury or a young user swings the table tennis ball vigorously, the table tennis racket is easily slipped out of the hand due to the reduced friction caused by the user's insufficient grip under the action of centrifugal force and inertia, and the practical effect needs to be improved.

By adopting the above technical solution, the thumb is inserted into the thumb ring during use, so that the palm and the racket body can be more firmly connected. When the user's hand loses strength, the racket body can be prevented from falling out of the hand by relying on the hook connection between the thumb ring and the thumb. The user can fully carry out force training to improve the upper limit of his or her own hitting force. The single thumb ring structure can be used when the racket is held with the thumb and index finger, or when the racket is held horizontally with five fingers, and has good adaptability.

Furthermore, a connecting column extending from the outer edge of the thumb ring and penetrating through the gripping handle is provided, and the connecting column is threadedly connected to the gripping handle.

By adopting the above technical solution, the threaded connecting column is rotatably connected to the gripping handle.

Furthermore, the gripping handle is provided with a pair of pluggable locking columns, and the locking columns are vertically provided through the connecting columns.

By adopting the above technical solution and the pluggable design of the locking column, it is possible to choose whether to lock the connecting column to switch the rotation state of the thumb ring according to actual needs.

Furthermore, a U-shaped pull ring is rotatably connected to one end of the locking column, and different locking columns are rotatably connected to both ends of the U-shaped pull ring. An outward-expanding protrusion is fixedly provided on the end of the locking column away from the U-shaped pull ring, and a deformation groove matching the outward-expanding protrusion is formed on the end surface of the locking column away from the U-shaped pull ring, and an outward-expanding groove matching the outward-expanding protrusion is formed on the outer wall of the grasping handle.

By adopting the above technical solution, when using, pull the U-shaped pull ring hard, and the outward-expanding protrusion will be squeezed and deformed toward the middle deformation groove under the extrusion of the outward-expanding groove. After reaching a certain degree of deformation, it can be detached from the gripping handle. At this time, the locking state of the thumb ring can be released. When it is necessary to lock the connecting column, insert the locking column into the gripping handle and the connecting column until the outward-expanding protrusion opens and fits the outward-expanding groove.

Furthermore, a storage groove for folding and storing the U-shaped pull ring is provided on the outer wall of the gripping handle, the U-shaped pull ring is a magnetic metal ring, and a magnetic attraction sheet is fixedly provided on the bottom wall of the storage groove.

By adopting the above technical solution, the storage groove can be set up for the U-shaped pull ring to be folded and stored, and the U-shaped pull ring can be adsorbed and fixed in the storage groove in combination with the magnetic suction sheet, so as to prevent the U-shaped pull ring from protruding outside and affecting the use of the table tennis racket.

Furthermore, a counterweight bar is embedded in one end of the ball board body away from the gripping handle, and the counterweight bar is embedded in the outer edge of the ball board body in an arc shape. The counterweight bar is penetrated by a plurality of locking screws threadedly connected to the ball board body.

By adopting the above technical solution, the weight of the matching counterweight bar is not limited, which can effectively increase or decrease the overall weight of the table tennis racket, allowing users to choose the appropriate weight for use, thereby increasing the applicability of the table tennis racket and improving the user experience.

In summary, the beneficial technical effects of the utility model are:
