Description

Technical Field

[0001] This utility model relates to the field of sports equipment technology, and in particular to a detachable barbell assembly device. Background Technology

[0002] A barbell assembly is a training device that combines a standard barbell bar into segments using tubing, threads, or other connection methods. The segments are tightly connected and can withstand a certain weight. It consists of the barbell bar, connecting parts, and related accessories, such as spring pins and slotted flat-end set screws, to achieve convenient assembly and stable connection.

[0003] The detachable barbell assembly is a device composed of multiple barbell sections and matching connectors. Each section can be quickly disassembled and assembled to meet the needs of portability and flexible use. The mechanical structure of the connectors firmly connects the barbell sections into a whole. When under load, the shear and tensile strength of the connectors is used to transmit force, ensuring the stability after assembly. When disassembling, the connecting structure is removed to separate the bar.

[0004] In the existing technology, some barbell bar combination devices have problems such as complex connection structure and insufficient stability, although the existing detachable barbell bar has improved portability through segmented design. Some products use simple threaded connection, which is prone to wear and loosening after long-term use. In addition, the counterweight wheel is fixed by a single thread locking and lacks an auxiliary limiting structure, which poses a risk of falling off. Therefore, a detachable barbell bar combination device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a detachable barbell assembly device, which aims to improve the problem of loosening caused by easy wear of threads after long-term use in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A detachable barbell assembly includes a bar body with multiple connecting rings threaded to its external surface. Two counterweight wheels are also threaded to the bar body. Each counterweight wheel has a connecting groove inside. A connecting block is fixedly connected to the top of the connecting groove. A driven groove is formed inside the connecting block. Two springs are fixedly connected to the bottom inner wall of the driven groove. A connecting block is fixedly connected to the top of the two springs. Multiple limiting holes are formed at the temporal portion of the connecting block. Positioning pins are provided on the inner walls of the limiting holes. A driven plate is rotatably connected to the top of one connecting block, and a connecting groove is formed inside the driven plate. A linkage plate is rotatably connected to the top of the other connecting block. Multiple adjustment components are sleeved on the exterior of both bar bodies.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 3 This utility model provides an embodiment of a detachable barbell assembly device, including a bar body 1, which provides connection and support for the two side components. Multiple connecting rings 2 are threaded onto the external surface of the bar body 1, providing fixation and support for connecting blocks 5. Two counterweight wheels 3 are threaded onto the external surface of the bar body 1, and the two counterweight wheels 3 can be added according to training requirements. Connecting grooves 4 are provided inside the counterweight wheels 3. After the linkage plate 13 and the connecting groove 12 are engaged, the counterweight wheel 3 is engaged and locked into the inner wall of the connecting groove 4, thereby achieving the limitation and fixation of the counterweight wheel 3, while also ensuring a neat and aesthetically pleasing appearance. A connecting block 5 is fixedly connected to the top of the connecting ring 2, providing space for a driven groove 6. The driven groove 6 is provided inside the connecting block 5, providing fixation and support for a spring 7.

[0034] Two springs 7 are fixedly connected to the bottom inner wall of the driven groove 6. Springs 7 have an elastic function, providing elastic support for the connecting block 8. Connecting blocks 8 are fixedly connected to the top of the two springs 7, providing space for the limiting holes 9. Multiple limiting holes 9 are formed inside the connecting block 8. When limiting and fixing counterweight wheels 3 of different sizes, pulling the connecting block 8 simultaneously stretches the springs 7, allowing for adaptive adjustment based on the elasticity of the springs 7. Positioning pins 10 are provided on the inner wall of the limiting holes 9, allowing the positioning pins 10 to be inserted into the corresponding positions of the limiting holes 9, thereby achieving the effect of fixing the upper limiting components. In preparation for subsequent splicing and positioning, a driven plate 11 is rotatably connected to the top of one of the connecting blocks 8. The driven plate 11 provides space for the connecting groove 12. The connecting groove 12 is opened inside the driven plate 11. The connecting groove 12 can cooperate with the linkage plate 13 to complete the positioning and fixing of the counterweight wheel 3. The top of the other connecting block 8 is rotatably connected to the linkage plate 13. The linkage plate 13 is used to snap into the interior of the connecting groove 12 to complete the splicing. This allows the outer parts of the linkage plate 13 and the driven plate 11 to be smoothly snapped into the interior of the connecting groove 4, which can limit and fix the counterweight wheel 3 for a neat and aesthetically pleasing appearance. Multiple adjustment components are sleeved on the outside of the two rods 1.

[0035] Reference Figure 4 and Figure 5The adjustment assembly includes a sleeve 14, which provides space for the positioning holes 15. Multiple positioning holes 15 are provided inside the sleeve 14, which limit the adjustment grooves 16, thereby limiting the rod body 1. Two adjustment grooves 16 are provided inside the rod body 1, which provide fixation and support for the second spring 17. The second spring 17 is fixedly connected to the bottom inner wall of the adjustment groove 16. The second spring 17 has an elastic function, providing elastic support for its positioning block 18. The positioning block 18 is fixedly connected to the top of the second spring 17. When adjusting the length according to different user needs, the positioning block 18 can be pressed to disengage it from the positioning holes 15, thereby adjusting the length of the rod body 1. After adjustment, the positioning block 18 resets due to the elasticity of the second spring 17 and engages with the corresponding positioning hole 15, thus completing the connection and fixation. The sleeve 14 is sleeved over the outside of the rod body 1, and the rod body 1 provides support for the sleeve 14.

[0036] Reference Figure 1 , Figure 2 and Figure 4 The external of the connecting block 8 is slidably connected to the inside of the driven groove 6. The driven groove 6 provides a limiting and guiding function for the connecting block 8. The external of the positioning pin 10 is in contact with the inner wall of the connecting block 5. By inserting the positioning pin 10 through the connecting block 5 into the limiting hole 9, the connecting block 8 is limited and fixed. The external of the linkage plate 13 is in contact with the inner wall of the connecting groove 12. The linkage plate 13 is inserted into the inside of the connecting groove 12 to complete the splicing. The bottom of the linkage plate 13 is in contact with the bottom of the connecting groove 12 and the inner wall of the connecting groove 4. After the linkage plate 13 and the driven plate 11 are engaged, they can be smoothly inserted into the inside of the connecting groove 4, thereby limiting and fixing the counterweight wheel 3. The external of the positioning block 18 is in contact with the inner wall of the positioning hole 15. The positioning hole 15 can limit the positioning block 18.

[0037] The external sliding connection of rod 1 is inside sleeve 14, which provides limiting and guiding functions for rod 1. Positioning block 18 is pressed out of the positioning hole 15. By pressing positioning block 18, spring 17 is squeezed out of the positioning hole 15, allowing the length of rod 1 to be adjusted. Linkage plate 13 and connecting groove 12 engage to complete splicing. After linkage plate 13 and connecting groove 12 engage, linkage plate 13 and driven plate 11 are spliced. Connecting block 8 adapts to the size of counterweight wheel 3 through spring 7. Connecting block 8 can adapt to different sizes of counterweight wheel 3 through the elastic action of counterweight wheel 3 for fixation. After linkage plate 13 and connecting groove 12 engage, they are inserted into connecting groove 4 to limit the counterweight wheel 3. After linkage plate 13 and driven plate 11 are spliced, they can be smoothly inserted into connecting groove 4 to limit and fix the counterweight wheel 3.

[0038] Working principle: In use, the connecting ring 2 is rotated to move and position itself on the rod 1, and is fixed on the left and right sides of the counterweight wheel 3. When it moves to the appropriate position, the connecting block 8 is pulled to slide in the driven groove 6, while the spring 7 is stretched. Then, the elasticity of the spring 7 adapts to the size of the counterweight wheel 3, and the linkage plate 13 and the connecting groove 12 of the driven plate 11 are engaged, so that the whole is inserted into the connecting groove 4 of the counterweight wheel 3. Then, the positioning pin 10 is inserted and passes through the locking limit hole 9 of the connecting block 5 to complete the limiting and fixing of the counterweight wheel 3. When disassembling, the positioning pin 10 is pulled out, the linkage plate 13 is pulled away from the connecting groove 12, and the counterweight wheel 3 can be removed. The connecting ring 2 and the counterweight wheel 3 are disassembled by rotating the thread, which can achieve quick disassembly and assembly.

[0039] When adjusting the length of the rod 1, press the positioning block 18 to compress the second spring 17 and disengage it from the positioning hole 15 of the sleeve 14. This causes the rod 1 to slide within the sleeve 14 to adjust its length. Then, the elastic reset of the second spring 17 causes the positioning block 18 to engage with the new positioning hole 15 and lock in place. When the rod 1 needs to be extended, pull the rod 1 outward. The positioning block 18 moves within the adjustment groove 16 to the corresponding positioning hole 15 and automatically engages. When the rod needs to be shortened, press the positioning block 18 and push the rod 1 inward. Repeat the positioning process to achieve adaptive length adjustment under different training scenarios.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
