Abstract: The invention relates to a phosphor with garnet structure and a light-emitting device comprising the phosphor, wherein the phosphor includes the following components in percentage by weight: 38.47-45.19% of Y element, 9.49-22.09% of Al element, 2.06-24.31% of Ga element, 27.3-32.04% of O element, 0.43-1.46% of Ce element. In the phosphor particles, the shortest distance from the surface of one side of the particle to the surface of the opposite side through the centroid of the particle is defined as R, the longest distance is R1, and 5 ?m?R?40 ?m; any distance from the particle surface to the centroid is r, and 0<r<½R; and the space with the distance from the particle surface to the centroid direction being less than or equal to r is defined as rinner.

Abstract: The present invention provides a dual-functional strap fitting for dumbbell assembly comprising: a middle strap; a first fabric strap and a second fabric strap coupled respectively to the middle strap, each of the first fabric strap and the second fabric strap including a thickened end; two buckles each including a slot, wherein the two buckles are slidably positioned on the first fabric strap and the second fabric strap through the slots, respectively, and the width of the slot is less than the thickness of the thickened end; fastening means positioned on a surface of the first fabric strap, a surface of the second fabric strap and a surface of the middle strap; and a coupling device positioned in the middle of the middle strap. The dual-functional strap fitting for the dumbbell assembly according to the present invention combines the functions of a handle strap and a coupling strap. Consequently, the cost for the dumbbell assembly is reduced.

Abstract: A multifunctional dumbbell assembly is provided, which comprises a dumbbell body and a handle strap which is detachably connected to the dumbbell body. The dumbbell body includes a handle, a first head and a second head. The heads are fixed to the opposite ends of the handle respectively. The handle strap includes a strap and two connectors which are connected to the ends of the strap respectively. Each of the first head and the second head includes: an end cover covering an end of the dumbbell body; a first coupling member having a central through hole and a cavity, an arc groove being formed in the cavity; and a second coupling member having clutch block (151) at one end, the shape of which is complementary to that of the cavity in the first coupling member, further having connector attachment portions, the second coupling member being also provided with a through hole. The dumbbell assembly is convenient and safe for use. In addition, it provides an additional exercise function.
