Disclosure of Invention

The invention aims to provide a barbell buckle to solve the technical problems that in the prior art, the locking space of the barbell buckle is fixed and cannot be adjusted, the barbell buckle is easy to slip after being locked on a barbell rod, the manufacturing cost is high, the operation is complex, and the function is single.

The technical scheme adopted for realizing the purpose of the invention is as follows:

a first aspect of an embodiment of the present invention provides a barbell fastener, including a snap spring member; the clamp spring piece comprises a first clamping rod, an arc-shaped body and a second clamping rod which are sequentially connected, and the arc-shaped body is made of a metal material; the extension line on the extending direction of the first clamping rod and the extension line on the extending direction of the second clamping rod are intersected in the region surrounded by the arc-shaped body, and an included angle between the extension line on the extending direction of the first clamping rod and the extension line on the extending direction of the second clamping rod is an acute angle.

Optionally, the first clamping bar, the arc-shaped body and the second clamping bar are all made of metal materials, and the first clamping bar, the arc-shaped body and the second clamping bar are sequentially connected to form an integrally formed structure.

Optionally, the first clamping bar and the second clamping bar are covered by rubber sleeves.

Optionally, the arc-shaped body is externally coated with a rubber sleeve.

Optionally, the rubber sleeve is made of rare earth butadiene rubber.

Optionally, the first clamping bar and the second clamping bar are both made of rubber; and one end of the arc-shaped body is injection molded inside the first clamping rod, and the other end of the arc-shaped body is injection molded inside the second clamping rod.

Optionally, an included angle between the first clamping bar and the plane where the arc-shaped body is located and an included angle between the second clamping bar and the plane where the arc-shaped body is located are acute angles.

Optionally, the barbell buckle further comprises a locking member, and the locking member is used for locking the first clamping bar and the second clamping bar under the condition that the first clamping bar and the second clamping bar are close to each other.

Further optionally, the locker comprises a locker body, and both ends of the locker body are respectively bent in the directions facing each other to form a hook shape; the clamping device is configured in such a way that under the working condition that the first clamping rod and the second clamping rod are close to each other, one end of the locking piece body is hooked at the position where the first clamping rod is connected with the arc-shaped body, and the other end of the locking piece body is hooked at the position where the second clamping rod is connected with the arc-shaped body, so that the first clamping rod and the second clamping rod are locked.

In addition, a second aspect of an embodiment of the present invention further provides a barbell to which the barbell fastener according to any one of the above embodiments is attached.

Compared with the prior art, the embodiment of the invention has the following beneficial effects:

A first aspect of an embodiment of the present invention provides a barbell fastener, where the barbell fastener includes a snap spring member, and the snap spring member includes a first clamping bar, an arc-shaped body, and a second clamping bar, which are connected in sequence; the arc-shaped body is made of metal material; the extension line of the first clamping rod in the extension direction and the extension line of the second clamping rod in the extension direction are intersected in the area surrounded by the arc-shaped body, and an included angle between the extension line of the first clamping rod in the extension direction and the extension line of the second clamping rod in the extension direction is an acute angle.

In the embodiment of the invention, the barbell weight can be firstly arranged on the barbell bar, the arc-shaped body of the barbell buckle is sleeved on the barbell bar, the arc-shaped body is attached to the barbell weight, then the first clamping rod and the second clamping rod are mutually close by holding the first clamping rod and the second clamping rod, and then the connecting part of the first clamping rod and the arc-shaped body and the connecting part of the second clamping rod and the arc-shaped body are locked by using structural members such as ropes or metal wires, so as to fix the first clamping rod and the second clamping rod, thereby realizing the fixing function of the barbell weight.

In the structure of barbell buckle that this embodiment provided, because the arc body is made by having elastic metal material to, under the operating mode that first clamping bar and second clamping bar are close to each other, have the motion trend of keeping away from each other all the time between first clamping bar and the second clamping bar, contained angle after first clamping bar and the locking of second clamping bar can carry out nimble regulation according to the diameter of barbell bar, thereby, is difficult for droing after the locking. Through a plurality of tests, in a locking state, the locking force value of the clamp spring piece on the barbell rod can bear more than 105kg of weight, the locking force value exceeds twice of the locking force value which can be provided by the barbell buckle in the prior art, and the locking state is more reliable; in addition, the barbell buckle that this embodiment provided has simple structure, makes convenient, the low beneficial effect of processing cost, no matter operate this barbell buckle so that this barbell buckle is in locking state or release state, operation process all only needs one to operate, and the processing procedure weak point consuming time, has the beneficial effect that the using-way is comparatively simple, the operation of being convenient for.

In addition, the clamp spring piece in the barbell buckle provided by the embodiment of the invention not only has the function of clamping and fixing the barbell weight, but also can be used for human body exercise. Specifically, the barbell can only exercise the large arm part of the human arm by lifting or falling, but cannot exercise the small arm part of the human arm. In contrast, in the embodiment of the present invention, the circlip member may be used to exercise the small arm of the human body, and the exercise process is as follows: when the first clamping rod and the second clamping rod are held by hands to enable the first clamping rod and the second clamping rod to be close to each other, muscles on the small arm of the arm of a human body are in a tight state, and when the hand is loosened, the first clamping rod and the second clamping rod are far away from each other under the action of resilience force generated after the arc-shaped body is compressed, so that the first clamping rod and the second clamping rod return to the initial positions; at the moment, the first clamping rod and the second clamping rod are held again to enable the first clamping rod and the second clamping rod to be close to each other, the purpose of exercising the small arms of the human arms can be achieved through repeated actions, and when the small arms of the human arms are exercised, nerves and muscles on hands of people are also exercised.

In addition, a second aspect of the embodiments of the present invention further provides a barbell, in which the barbell buckle is installed. The barbell provided by the second aspect of the embodiment of the invention can achieve all the beneficial effects that the barbell buckle can achieve.
