Abstract: A volleyball training device has a training state and a using state, including a base, a volleyball net component, and an interception net component. The volleyball net component and the interception net component are detachably connected to the base. In the using state, the volleyball net component is connected to the base, and the interception net component is detached from the base. In the training state, the volleyball net component is connected to the base, and the interception net component is connected to the base. Through the structure above, when in the training state, the interception net component can intercept the volleyball that passes an upper end of the volleyball net component, facilitating a user's practice of volleyball actions such as serving and spiking. When in the using state, only the volleyball net component is connected to the base, and the user can normally hit the volleyball.

Abstract: An optical assembly, a linear lamp, a linear lamp combination and a track linear lamp are provided, the optical assembly includes a light source module, a reflective cup, a lens component, and an anti-glare cup which are sequentially arranged in a height direction, in which an edge of the reflective cup is provided with a snap-fit slot, and an edge of the lens component is provided with a first hook in a protruding manner, the anti-glare cup is provided with a second hook in a protruding manner, the first hook and the second hook extend in a same direction so as to be inserted into a corresponding snap-fit slot, and the reflective cup, the lens component, and the anti-glare cup are connected in a snap-fit manner.

Abstract: The present disclosure discloses a light distributing component and a lighting apparatus. The light distributing component includes a first lens and a first clamp holding portion; the first lens has a first light incident surface, a first light emergent surface, and a side portion located between the first light incident surface and the first light emergent surface; the first clamp holding portion is arranged on the side portion of the first lens; wherein, the first lens is a light path deflecting element, and an included angle is between the first light incident surface and the first light emergent surface; the first light incident surface is arranged on a transmission path of emergent light of the lighting apparatus, and is used to receive the emergent light; and the first light emergent surface emits out the emergent light to change a propagation path of the emergent light.

Abstract: A swingset includes at least two support frames distributed at intervals and a connecting rod assembly configured to connect the at least two support frames. The connecting rod assembly has a length direction and includes a first connecting rod, a second connecting rod, and a reinforcing member. The first connecting rod and the second connecting rod are arranged in sequence along the length direction. The reinforcing member overlaps a joint of the first connecting rod and the second connecting rod, and the reinforcing member is detachably connected to the first connecting rod and the second connecting rod. The reinforcing member is configured to disperse force at the joint of the first connecting rod and the second connecting rod during operation of the swingset, and weaken tension at the joint during operation of the swingset.
