Description

High barbell weight plate of security solid fixed ring

Technical Field

The utility model belongs to a body-building apparatus, concretely relates to high solid fixed ring of barbell weight plate of security.

Background

Dumbbells and barbells are commonly used to exercise physical strength. These strength training devices can come in a variety of configurations. For example, barbells can be classified into fixed barbells and adjustable barbells. The fixed barbell has a pair of weights connected to a handle. Because each fixed barbell has a predetermined weight, one would need a different set of barbells to have a different weight. Many stationary barbells would be expensive to purchase and take up a lot of space to store. Therefore, adjustable barbells have become popular in recent years.

Adjustable barbells typically include a set of weights that allow the user to select a desired weight prior to use. Thus, a single adjustable barbell may suffice for the user's needs. The design of the adjustable barbell is simple and complex. A simple design of an adjustable barbell is to use individual disc-shaped weights with a hole in the center for receiving a handle. The user will select a plurality of disc-shaped weights and then fasten them to the handle by a locking mechanism (e.g., a locking tab or nut). More complex designs of adjustable barbells will include some selection mechanism that allows the user to select the desired weight and easily lock the weight to the handle. The selection mechanism may be an internal mechanism or an external mechanism (e.g., a rack and pinion mechanism), i.e., housed in the handle or external to the handle.

For example, U.S. patent No. 6,261,022 to Dalebout et al discloses an external mechanism in which a rotatable clamping member is attached to a cross member on the handle. The clamping members can be rotated to different angles to engage different sets of weights via the rails connecting the pairs of weight plates. The internal mechanism is housed in the handle and typically includes a pair of slide bars inside the handle. The sliding rods can be extended or retracted to engage different numbers of weight plates on both ends of the handles. The sliding mechanism typically comprises a rack and pinion or similar design.

For example, U.S. patent No. 7,090,625 to cherrack discloses a design containing a rack and pinion device in the handle, a transmission mechanism to move two extendable elements, a locking mechanism, and a nested weight unit with rods attached to the sides of the plates for support. While prior art adjustable barbells provide a convenient choice for the user, there is still a need for better designs for adjustable barbells.

The patent number 201520625125.3's chinese utility model patent discloses a solid fixed ring of barbell weight plate, include with barbell bar matched with part and can open the device of locking, the part includes a plurality of arc snap rings through hinged joint, the device that can open locking is including setting up the auto-lock safety button on the head snap ring, handle through bolt and head snap ring connection, the setting is at the connector that head snap ring was served, the other end setting of connector is at the tail snap ring, the connector is the connection piece that the multi-disc passes through bolted connection, the connection piece can be followed the bolt direction and folded, be provided with the bayonet socket on the handle, be provided with the buckle of holding with bayonet socket looks card on the auto-lock safety button. Thereby auto-lock safety is detained and is realized the fixed of handle and loosen through its self elastic deformation and make the fixed safer change of balancing weight more convenient among the above-mentioned technical scheme. Meanwhile, the fixing ring can be used on a dumbbell, so that the dumbbell and the barbell can share one set of balancing weight. However, in the technical scheme, the elastic deformation of the material of the part is used for working, so that stress concentration is easily caused, and fatigue fracture of the material is easily caused when the part is used for a long time, thereby bringing potential safety hazards.
