Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0011] The pin rod locking barbell is composed of an anti-slip cover 1, a handle 2, a weight plate 3, a locking rod 4, a spring 5, a rod hole 6 and a fixing ring 7. Wherein, the anti-slip cover 1 is a rubber cover whose outer surface is curved, and the anti-slip cover 1 is set on the groove in the middle part of the handle 2 . The distance from each end of the handle 2 is 1 / 4 of the length of the handle 2. There is a fixed ring 7, and the fixed ring 7 is an integral ring with the handle 2. The weight disc 3 is a plurality of oblate cylinders with different diameters, a circular through hole in the middle and the same thickness. The weight disc 3 is set on the handle 2 and has a dynamic cooperation relationship with the handle 2. The rod hole 6 is a blind hole on the surface of the handle 2 between the fixing ring 7 and the end of the handle 2 . The di...

Abstract

The invention relates to a sport facility, in particular to a pinrod lashing type barbell which is constructed by an anti-skidding sleeve, a grab handle, a weight tray, lashing rods, a spring, a rod hole and fixing rings. The position 1 / 4 length of the grab handle away from each end of the grab handle is respectively provided with a fixing ring. The weight tray is sheathed on the grab handle and in dynamic match relation with the grab handle. The rod hole is a blind hole positioned on the surface of the grab handle and between the fixing rings and the ends of the grab handle. The spring and the column-shaped lashing rods are positioned in each rod hole, and the lashing rods and the rod holes are in dynamic match relation. The upper end of the spring and the lower end of lashing rods are welded, the lower end of the spring and the bottom of the rod holes are welded, and the upper end of the lashing rod is of hemisphere shape. The invention not only is very fast in operation, but also eliminates potential safety hazard caused by slipping of the weight tray in the motion of the barbell.

Description

technical field [0001] The invention relates to a sports apparatus, in particular to a barbell locked by pins. Background technique [0002] Existing barbells are usually made of lead-filled handles with threads at both ends and weights screwed on the two ends of the handles. Because in the process of lifting and lowering the barbell, the human hand will exert a certain torque on the barbell, and because there is a large difference between the inertia of the barbell as a whole and the inertia of the handle that is directly subjected to torsion, it often occurs that the weight is in the The case of counterclockwise rotation under the action of inertia and detachment from the handle. Once the weight is out of the handle, there will be a situation of injuring people or damaging property, which is a safety hazard for barbell sports. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the present invention provides a pin-locked barbell with...
