Description

Technical Field

[0001] This utility model belongs to the field of fitness equipment technology, and in particular to a multifunctional dumbbell and barbell combination. Background Technology

[0002] A barbell is a core training exercise tool used in weightlifting. Dumbbells are auxiliary equipment for weightlifting and fitness exercises, and are smaller than barbells. A multi-functional dumbbell-barbell combination is two dumbbells combined into one barbell, and can be easily disassembled and used. However, the connection methods of existing dumbbell-barbell combinations are relatively cumbersome.

[0003] A multifunctional dumbbell and barbell combination is proposed to solve the problem of the cumbersome connection method of dumbbell and barbell combinations. Utility Model Content

[0004] The purpose of this invention is to provide a multifunctional dumbbell and barbell combination to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional dumbbell and barbell combination, comprising:

[0006] The barbell bar is cylindrical in shape, with two symmetrically arranged dumbbell bodies on each end face;

[0007] Two locking assemblies are used to connect the barbell bar and the dumbbell body. They are located on the adjacent sides of the barbell bar and the dumbbell body. The locking assemblies include a support block with a concave bottom and a fixed post with a hollow side. The end face of the fixed post is in rotatable frictional contact with the support block. T-shaped clamping blocks for fixing the dumbbell body are embedded and slidably connected on both sides of the fixed post. The centrifugal side of the two clamping blocks is inclined. Two pressure springs are provided on the side of the clamping blocks near the fixed post. The lower part of the fixed post is provided with a movable sleeve and a support bottom ring.

[0008] Preferably, the side of the support bottom ring is connected and fixed to the inner cavity of the support block, and the top surface of the support bottom ring is in rotatable frictional contact with the fixed column.

[0009] Preferably, the inner annular surface of the movable sleeve is threaded to the fixed column, and the inner cavity of the movable sleeve is connected to an inclined clamping ring for abutting against two clamping blocks.

[0010] Preferably, the outer curved surface of the movable sleeve is connected to several sliders, and the inner cavity of the support block is provided with several grooves for the sliders to slide.

[0011] Preferably, the dumbbell body includes a dumbbell bar and several pairs of dumbbell weight plates, with the sides of the dumbbell weight plates being embedded and fixedly connected to the dumbbell bar.

[0012] Preferably, the support block has a through slot on the side away from the fixed post for inserting the dumbbell bar.

[0013] Preferably, the inner ring surface of the fixed column has two symmetrically arranged limiting blocks, and the side of the dumbbell bar has two sliding grooves for the limiting blocks to slide.

[0014] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0015] This multi-functional dumbbell barbell combination consists of a barbell bar and two dumbbell bodies. The barbell bar and the two dumbbell bodies are connected by two locking assemblies to form a barbell shape. At the same time, the two dumbbells can be easily disassembled, realizing the multi-functional use characteristics of the dumbbell barbell combination.

[0016] This multi-functional dumbbell and barbell combination features a locking mechanism that, when connecting the barbell bar to the dumbbell body, allows the dumbbell bar to extend into the inner cavity of the support bottom ring and the movable sleeve. This causes the dumbbell body to rotate, which in turn rotates the dumbbell bar. With the connection of the limiting block, the fixed column and the dumbbell bar rotate synchronously and in the same direction. This causes the movable sleeve to move along the threaded path of the fixed column, which in turn moves the clamping ring. Under the push of the clamping ring, two clamping blocks extend into the inner cavity of the fixed column, thus clamping the dumbbell bar together. This provides a convenient connection and fixation for the dumbbell body, making it simple to operate and more convenient to use.

[0017] This multi-functional dumbbell and barbell combination allows for easy disassembly of the dumbbell body by rotating it in the opposite direction. During this process, the moving sleeve moves away from the fixed post, releasing the clamping ring from the two clamping blocks. Under the elastic thrust provided by the pressure spring, the two clamping blocks are released from their contact with the dumbbell bar, facilitating the easy disassembly of the dumbbell body and improving the usability of the multi-functional dumbbell and barbell combination. At the same time, the slider prevents the moving sleeve from rotating synchronously with the fixed post, improving the structural stability of the components of the multi-functional dumbbell and barbell combination.

In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0029] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0030] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0031] Please see Figures 1 to 4 A multi-functional dumbbell and barbell combination, as described in this embodiment, includes:

[0032] The barbell bar 1 is cylindrical in shape. The surface of the barbell bar 1 is fitted with a rubber anti-slip sleeve. The surface of the anti-slip sleeve has several corrugated grooves to increase surface friction resistance and enhance the comfort of use. Two dumbbell bodies 2 are symmetrically arranged on each end face of the barbell bar 1, so that the barbell bar 1 and the two dumbbell bodies 2 can be combined to form a barbell. At the same time, the two dumbbell bodies 2 can be easily disassembled to adapt to usage needs and realize the multi-functional use characteristics of the dumbbell barbell combination.

[0033] Two locking assemblies 3 are used to connect the barbell bar 1 and the dumbbell body 2. They are located on adjacent sides of the barbell bar 1 and the dumbbell body 2. Each locking assembly 3 includes a support block 31 with a concave bottom and a fixing post 32 with a hollow side. The two support blocks 31 are connected and fixed to the barbell bar 1 on adjacent sides. The fixing post 32 is located in the inner cavity of the support block 31. The end face of the fixing post 32 is in rotatable frictional contact with the support block 31. The fixing post 32 can rotate relative to the support block 31. T-shaped clamping blocks 35 for fixing the dumbbell body 2 are slidably connected to both sides of the fixing post 32. The centrifugal side of the two clamping blocks 35 is inclined, and the inclined surface of the two clamping blocks 35 is located on the side away from the barbell bar 1, clamping... Two pressure-boosting springs 36 are provided on the side of block 35 near the fixed post 32. Two symmetrically arranged T-shaped sliding grooves are opened on the side of the fixed post 32, and both sliding grooves of the fixed post 32 are connected to the inner cavity of the fixed post 32. The inner wall of the sliding groove of the fixed post 32 is slidably connected to the abutting block 35. The four pressure-boosting springs 36 are divided into two groups, and each group of pressure-boosting springs 36 is set in the inner cavity of the sliding groove of the fixed post 32. At the same time, all four pressure-boosting springs 36 are connected and fixed to the fixed post 32. The lower part of the fixed post 32 is provided with a movable sleeve 33 and a support bottom ring 34. The movable sleeve 33 is located on the upper part of the support bottom ring 34. Two locking assemblies 3 are symmetrically arranged on the two ends of the barbell bar 1.

[0034] The side of the support bottom ring 34 is fixedly connected to the inner cavity of the support block 31, and the side of the support bottom ring 34 away from the barbell bar 1 is flush with the side of the support block 31 away from the barbell bar 1. The top surface of the support bottom ring 34 makes rotational friction contact with the fixed post 32, causing the fixed post 32 to rotate within the inner cavity of the support block 31. The inner ring surface of the movable sleeve 33 is threadedly connected to the fixed post 32. When the fixed post 32 rotates, the movable sleeve 33 moves along the threaded path of the fixed post 32. The inner cavity of the movable sleeve 33 is connected to an inclined clamping ring for abutting against two clamping blocks 35. When the movable sleeve 33 moves toward the barbell bar 1, it drives the clamping ring to move synchronously and in the same direction, causing the clamping ring to press against the two clamping blocks 35, so that the two clamping blocks 35 extend into the inner cavity of the fixed post 32. During the centripetal movement of the two clamping blocks 35, the dumbbell body 2 is clamped and fixed. Simple and easy to operate, this dumbbell and barbell assembly allows for convenient disassembly and assembly. The outer curved surface of the movable sleeve 33 is connected to several sliders. The inner cavity of the support block 31 has several grooves for the sliders to slide. The sliders prevent the movable sleeve 33 from rotating within the inner cavity of the support block 31, improving the structural stability of the dumbbell and barbell assembly. The dumbbell body 2 includes a dumbbell bar 21 and several pairs of dumbbell weight plates 22. The sides of the weight plates 22 are embedded and fixedly connected to the dumbbell bar 21. The support block 31 has a through slot on the side away from the fixed post 32 for the dumbbell bar 21 to insert into. The inner ring surface of the fixed post 32 has two symmetrically arranged limiting blocks. The side of the dumbbell bar 21 has two grooves for the limiting blocks to slide. The two limiting blocks allow the fixed post 32 to rotate during the rotation of the dumbbell bar 21, providing conditions for the two clamping blocks 35 to clamp the dumbbell bar 21.

[0035] To install the barbell and dumbbell assembly, both ends of the barbell bar 1 are connected to the dumbbell bodies 2 via locking assemblies 3, forming a barbell by combining the barbell bar 1 with the two dumbbell bodies 2. The dumbbell bar 21 extends into the inner cavity of the support bottom ring 34 and the fixing post 32. Rotating the dumbbell body 2 causes the dumbbell bar 21 to rotate synchronously in the same direction. With the connection of the limiting block, the fixing post 32 rotates synchronously in the same direction as the dumbbell bar 21. Since the fixing post 32 is threadedly connected to the moving sleeve 33, the moving sleeve 33 moves along the threaded path of the fixing post 32, causing the moving sleeve 33 to move the clamping ring toward the barbell. As the barbell bar 1 moves, the clamping ring tightly abuts against the two clamping blocks 35. The inner ring surface of the clamping ring is inclined, and the inner ring surface of the clamping ring matches the inclined surface of the clamping block 35. This allows the clamping ring to push the two clamping blocks 35 to move as it moves toward the barbell bar 1. The two clamping blocks 35 extend into the inner cavity of the fixing post 32, clamping the dumbbell bar 21 and facilitating the installation and fixation of the dumbbell body 2. The slider prevents the sleeve 33 from rotating relative to the support block 31 within the inner cavity of the support block 31, further improving the structural stability of the dumbbell barbell assembly.

[0036] To disassemble the barbell and dumbbell assembly, the dumbbell body 2 is rotated in the opposite direction. During the transmission process, the moving sleeve 33 moves away from the barbell bar 1, releasing the clamping ring from the two clamping blocks 35. Under the elastic force provided by the pressure spring 36, the two clamping blocks 35 move centrifugally, releasing the clamping and fixing of the two clamping blocks 35 to the dumbbell bar 21, allowing the dumbbell body 2 to be easily disassembled. The dumbbell and barbell assembly connection structure is simple to operate and easy to use, improving the ease of use of the dumbbell and barbell assembly.

[0037] Working principle

[0038] In this multi-functional dumbbell and barbell combination, the barbell bar 1 is connected to the dumbbell body 2 at both ends via a locking assembly 3. This allows the dumbbell bar 21 of the dumbbell body 2 to extend into the inner cavity of the support bottom ring 34 and the fixing post 32, causing the dumbbell body 2 to rotate. During the transmission process, the fixing post 32 rotates, causing the moving sleeve 33 to move along the threaded path of the fixing post 32. The clamping ring abuts against two clamping blocks 35, which then clamp and fix the dumbbell bar 21 of the dumbbell body 2. Conversely, the dumbbell body 2 can be disassembled, enabling convenient installation and removal. Several sliders slide along several grooves in the support block 31, allowing the moving sleeve 33 to move smoothly.
