An easily assembled and disassembled frame for a net game includes a rigid multi-part frame with a cross-member that is non-sagging. Sections of the multi-part frame have an elliptical profile. A net stabilizer includes a tensioning member coupled at one end to a retention member of the frame, and having the other end of the tensioning member inserted into a center sleeve of the net, and, a center sleeve with a securing member for fastening securely at one end to the cross-member.

A net system used for example a sports game and a fine height adjustment system is provided. A cable mount is coupled to one or both of the upright posts with coarse height adjustment. A cable system for supporting the net includes a first end coupled to the upright post, and a second end coupled to a tension system of the other upright post. An intermediate portion of the cable system is slidably coupled along a pivoting member of the cable mount. The cable mount includes the fine height adjustment system that is coupled to the pivoting member. The pivoting member is pivotable in an upward direction or a downward direction upon movement of the fine height adjustment system without relieving tension from the cable system. The total distance of travel provided by fine height adjustment may be less than an incremental distance with coarse height adjustment.

The present application provides a net frame structure with an adjustable net height, the net frame structure comprising: a net, a suspending member being provided on each of left and right sides of the net; and two support members respectively arranged on the left and right sides of the net in an extended state, wherein each of the support members is provided with a plurality of height positioning portions, the plurality of height positioning portions are sequentially arranged at intervals in a height direction of the support member, a height at which each height positioning portion is located corresponds to a standard height of the net, and the height positioning portion is detachably connected to the suspending member, enabling the net to be maintained at a desired standard height. When the height of the net needs to be adjusted, it is only necessary to connect the suspending member on the net to a height positioning portion corresponding to the desired standard height, thus allowing the actual height of the net to correspond to the desired standard height, avoiding fluctuations of the actual height of the net, improving the height adjustment accuracy of the net, providing a simple structure, and making operations easy.
