Description

Technical Field

[0001] This utility model relates to the field of curved barbell technology, and in particular to a curved barbell that allows for quick and easy fixing of dumbbell plates. Background Technology

[0002] The origin of the barbell can be traced back to ancient times, when people used simple weights, such as stones tied to both ends of a stick, to train strength. With the development of fitness concepts and advancements in metal processing technology, the modern barbell gradually took shape. Publication number CN209270721U discloses a fitness barbell, relating to the field of fitness equipment technology. This utility model discloses a fitness barbell, including weight wheels and a bar. The weight wheels are installed at both ends of the bar and are eccentric wheels, rotatably connected to the bar. Thus, during exercise, not only can the traditional barbell workout be performed by lifting the barbell, but the weight wheels can also be rotated by shaking the barbell, creating an interaction between the exerciser's muscle movement and the barbell's rotation. This increases core muscle strength training, enhances the exerciser's interest, and enriches the exercise patterns. During fitness training, especially for time-sensitive exercises like high-intensity interval training or circuit training, the speed at which dumbbell plates are changed indirectly affects the rest time of the weights. Excessive changing times disrupt the training rhythm, reduce training effectiveness, and hinder the achievement of training goals, thus requiring improvement. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problems mentioned in the background art.

[0004] This utility model adopts the following technical solution: a curved barbell with quick dumbbell plate fixing, including a main bar, with limiting plates fixedly installed on both sides of the main bar, a loading sleeve fixedly installed on the surface of the limiting plates, a slide rail fixedly installed on the surface of the loading sleeve and having a first fixing groove, a dumbbell plate slidably connected to the surface of the loading sleeve, a positioning groove on the surface of the dumbbell plate, a retaining ring slidably connected to the surface of the slide rail, a first fixing block slidably connected inside the retaining ring, a first limiting rod and a first return spring fixedly installed on the surface of the first fixing block, a pressing block fixedly installed at one end of the first limiting rod, a second limiting rod slidably connected inside the retaining ring, a second return spring fixedly installed inside the second limiting rod, a pull ring fixedly installed at one end of the second limiting rod, a second fixing block fixedly installed on the surface of the pull ring, and a second fixing groove on the surface of the first fixing block.

[0005] Preferably, the surface of the first fixing groove is slidably connected to the first fixing block, the surface of the second fixing block is slidably connected to the second fixing groove, and the surface of the slide rail is slidably connected to the positioning groove. This allows the dumbbell plates to be quickly and stably fixed to the main bar.

[0006] Preferably, the surfaces of the first limiting rod, the second limiting rod, and the second fixing block are slidably connected to the retaining ring. This achieves a dual function of limiting and resetting, ensuring that the dumbbell plates will not accidentally fall off during use.

[0007] Preferably, one end of the first and second return springs is fixedly mounted between them and the retaining ring. This allows the retaining ring to automatically reset.

[0008] Preferably, a fixing sleeve and a raised ring are fixedly installed on the surface of the main bar, and an anti-slip sleeve is fixedly installed on the surface of the fixing sleeve. Here, the outer surface of the anti-slip sleeve is designed with dense anti-slip texture to increase the friction when the user grips it and prevent slippage during exercise. The raised ring enables the user to quickly and accurately place the barbell in the center of the body, ensuring the standardization and safety of the movement.

[0009] Preferably, the anti-slip sleeve is made of nitrile rubber. Nitrile rubber has good elasticity and high friction, making it suitable for various fitness environments, especially for training where the palms sweat a lot and require greater friction.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. In this utility model, by setting a slide rail and a positioning groove, the dumbbell plates, retaining rings, and pull rings can be quickly installed and positioned. The first fixing groove, the first limiting rod, the first return spring, the first fixing block, the pressing block, the retaining ring, the second limiting rod, the second return spring, the second fixing block, and the pull ring enable the quick assembly and disassembly of the dumbbell plates. The weight of the dumbbells can be adjusted according to different training plans and training goals, allowing users to quickly complete weight adjustments and reducing the time wasted on adjusting the dumbbell plates during component rest, thereby enabling the entire training plan to be completed efficiently.

[0012] 2. In this utility model, by setting a fixed sleeve, an anti-slip sleeve, and a raised ring, the anti-slip sleeve can improve the grip performance when the user holds the curved dumbbell bar for exercise, preventing sweat from falling on the handle and causing a loose grip. Furthermore, the raised ring can help the user quickly and accurately place the barbell in the center of the body when performing some balance-requiring movements (such as barbell bench press), ensuring the standardization and safety of the movement, and avoiding uneven force or injury due to barbell position deviation. This improves the training efficiency when the user holds the curved dumbbell bar for exercise. Attached Figure Description
