Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0035] refer to Figure 1-4 A specific embodiment of this utility model provides a weight plate locking mechanism for a fitness training machine, comprising:

[0036] Column 1;

[0037] Slider 2 is slidably connected to column 1 along the length of column 1.

[0038] The first end of the connecting rod assembly is inserted into the slider 2 and is detachably connected to the slider 2. The slider 2 is snapped into the column 1 through the connecting rod assembly. The counterweight plate 4 is installed on the connecting rod assembly and is limited between the second end of the connecting rod assembly and the slider 2.

[0039] Existing training machines are generally non-detachable and non-storable, occupying a large space and causing inconvenience in transportation and use. Furthermore, the components for installing and securing the counterweight plate cannot be separated from the main body of the training machine, making it difficult to meet users' storage needs and training requirements in different locations, thus affecting the user's training experience. In this application, the main function of the linkage assembly is to mount the counterweight plate 4 onto the slider 2. The linkage assembly can be detachably connected to both the counterweight plate 4 and the slider 2, without affecting the overall storage of the training machine, making it better suited for storable training machines. Overall, this application allows for quick disassembly of the counterweight plate 4 and its fasteners from the column 1, facilitating the storage of the entire training machine and making it more convenient to use.

[0040] Further optimization of the design includes the following linkage assembly:

[0041] Sleeve rod 3, the first end of sleeve rod 3 is inserted into slider 2, counterweight plate 4 is installed on sleeve rod 3, sleeve rod 3 passes through the center of counterweight plate 4;

[0042] Locking block 8 is sleeved on the first end of sleeve rod 3 and is detachably connected to sleeve rod 3. Slider 2 is engaged with column 1 through locking block 8.

[0043] When the counterweight plate 4 is installed on the sleeve rod 3, the locking block 8 is engaged with the column 1 through the sleeve rod 3. During training, it is necessary to unlock the slider 2. Specifically, push the sleeve rod 3 towards the slider 2 and move the locking block 8 a certain distance to disengage the locking block 8 from the column 1. At this time, the slider 2 and the counterweight plate 4 can be pulled by the pull rope 5.

[0044] Further optimizations to the plan include:

[0045] Positioning groove 13 is formed on column 1;

[0046] The locking block 14 is fixedly connected to the locking block 8 and extends out of the slider 2 to fit into the positioning groove 13.

[0047] When the locking block 14 is located in the positioning groove 13, the slider 2 is restricted to the column 1. At this time, when the pulling rope 5 is pulled, it cannot drive the slider 2. By pushing the sleeve rod 3 towards the slider 2, the locking block 14 is disengaged from the positioning groove 13.

[0048] Further optimizations to the plan include:

[0049] Disassemble link 7, and sleeve 3 is fitted onto the first end of disassembly link 7;

[0050] The sliding column 9 passes radially through the side wall of the sleeve rod 3 and is slidably connected to the sleeve rod 3. The centripetal end of the sliding column 9 is in contact with the first end of the disassembly connecting rod 7, and the centrifugal end of the sliding column 9 extends into the locking block 8.

[0051] The variable diameter connecting rod 11 has its small diameter end fixedly connected to the first end of the disassembly connecting rod 7 on the same axis, and the circumference of the large diameter end of the variable diameter connecting rod 11 is in contact with the radial end of the sliding column 9.

[0052] Spring 10 is arranged colinearly with the disassembly link 7 and abuts against the first end face of the disassembly link 7 and the inner wall of the locking block 8.

[0053] When the sleeve rod 3 is inserted into the slider 2, the circumference of the large-diameter end of the variable-diameter connecting rod 11 contacts the centripetal end of the sliding column 9, causing the centrifugal end of the sliding column 9 to extend into the locking block 8. The sleeve rod 3 is connected to the locking block 8, and the locking block 8 can move with the sleeve rod 3, thus realizing that the locking block 14 is in or out of the positioning groove 13. When it is necessary to store the column 1, the counterweight plate 4 and the sleeve rod 3 need to be removed first. Push the disassembly connecting rod 7 towards the slider 2, so that the disassembly connecting rod 7 slides in the sleeve rod 3, compressing the spring 10. The large-diameter end of the variable-diameter connecting rod 11 disengages from the sliding column 9, and the small-diameter end of the variable-diameter connecting rod 11 is in contact with the sliding column 9. At this time, the radial constraint of the sliding column 9 disappears. When the sleeve rod is moved away from the slider 2, 3. The slider 2 pushes the slide column 9 towards the small diameter end of the variable diameter connecting rod 11, but the slider 2 is not completely disengaged from the sleeve rod 3. The sleeve rod 3 is pulled out from the slider 2, and the column 1 can be accommodated. After the disassembly connecting rod 7 is released, under the elastic force of the spring 10, the large diameter end of the variable diameter connecting rod 11 pushes the centrifugal end of the slide column 9 out of the sleeve rod 3. When the sleeve rod 3 is reinstalled, the disassembly connecting rod 7 needs to be pushed to compress the spring 10, release the radial constraint on the slide column 9, insert the sleeve rod 3 into the slider 2, and the slide column 9 is squeezed into the sleeve rod 3, located at the small diameter end of the variable diameter connecting rod 11. After the sleeve rod 3 is inserted into place, the disassembly connecting rod 7 is released, and the slide column 9 is pushed out by the large diameter end of the variable diameter connecting rod 11 and extends into the locking block 8.

[0054] The scheme is further optimized so that the centrifugal end of the slide column 9 is positioned on the side near the second end of the disassembly connecting rod 7 and is axially aligned with the locking block 8.

[0055] This design ensures that the lever 3 is confined within the slider 2, guaranteeing safety during training.

[0056] Further optimizations to the plan include:

[0057] The receiving groove 12 is formed between the small diameter end of the variable diameter connecting rod 11 and the first end of the disassembly connecting rod 7.

[0058] When the sliding column 9 corresponds to the small diameter end of the variable diameter connecting rod 11, the moving sleeve 3 can squeeze the radial end of the sliding column 9 into the receiving groove 12, which facilitates the separation of the sleeve 3 from the slider 2.

[0059] Further optimizations to the plan include:

[0060] Quick-release connector 6 is installed at the second end of sleeve rod 3, and counterweight plate 4 is restricted between quick-release connector 6 and slider 2.

[0061] Once the sleeve rod 3 and slider 2 are installed, the counterweight plate 4 is placed on the sleeve rod 3, and a quick-release connector 6 is installed at the second end of the sleeve rod 3 to ensure that the counterweight plate is securely installed during training.

[0062] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
