[0021] The technical scheme in the utility model embodiment will be described clearly and completely in the utility model embodiment in the following, obviously, the described embodiment is only a part of the embodiment of the utility model, not all embodiments. Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor are within the scope of the utility model protection.

[0022] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The terms “comprising,” “including,” etc., as used herein indicate the presence of the stated features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0023] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein are to be interpreted in a manner consistent with the context of this specification, and not in an idealized or overly rigid way.

[0024] In the embodiments, by Figures 1-5 Give, Figure 1 This is a schematic diagram of a counterweight block assembly that is easy to install according to the present invention. It can be seen that the medium counterweight block can be set below the large counterweight block, and the small counterweight block can be set below the medium counterweight block.

[0025] Figure 2 This is a schematic diagram of the large counterweight block of this utility model. It can be seen that the large counterweight block has a connecting part at the top, a protrusion at the bottom, and a snap-fit ​​part on the side of the protrusion.

[0026] Figure 3 This is a schematic diagram of the snap-fit ​​joint of this utility model. It can be seen that the snap-fit ​​joint is composed of a vertical slide, a horizontal slide, and a magnetic sheet.

[0027] Figure 4 This is a schematic diagram of the counterweight block in this utility model. It can be seen that the top of the counterweight block is provided with a first recess, a locking block is provided on one side wall of the recess, and the bottom of the counterweight block is provided with a second recess.

[0028] Figure 5 This is a schematic diagram of the small counterweight of this utility model. It can be seen that a magnetic sheet is provided on the bottom surface of the small counterweight.

[0029] A conveniently installed counterweight assembly includes: a large counterweight 1 and a medium counterweight 2. The large counterweight 1 has a connecting part 11 on its top surface and a protrusion 12 on its bottom surface. The protrusion 12 has a locking part 121 on its side. The medium counterweight 2 is made of stainless steel and is located at the bottom of the large counterweight 1. The medium counterweight 2 has a recess 21 on its top surface and a locking block 212 is fixedly installed in the recess 21. The protrusion 12 can be inserted into the recess 21. The locking part 121 includes a vertical slide rail 1211 and a horizontal slide rail 1212 at the top of the vertical slide rail 1211. A magnetic piece 1213 is fixedly installed at one end of the horizontal slide rail 1212. The locking block 212 can be inserted into the horizontal slide rail 1212 and slide, and is attracted by the magnetic piece 1213.

[0030] The connection is threaded. During use, the large counterweight is connected via the thread to increase the counterweight. To further increase the counterweight, align the concave top surface of the middle counterweight with the convex bottom surface of the large counterweight, then push the locking block into the locking mechanism. The middle and large counterweights then combine to achieve the increased counterweight. To reduce the counterweight, simply disengage the middle counterweight and remove it from the large counterweight. Alternatively, as another locking method, push the locking block along the vertical slide, then rotate it along the horizontal slide until it contacts the magnetic plate, forming an attractive connection. To remove it, rotate the middle counterweight along the horizontal slide and then remove it from the vertical slide. The horizontal slide and magnetic plate design ensure a relatively stable combination of the middle and large counterweights, and the removal operation is simple and effortless.

[0031] In a preferred embodiment of this invention, a small counterweight 3 is provided at the bottom of the middle counterweight 2. The mass of the small counterweight 3 is smaller than that of the large counterweight 1 or the middle counterweight 2. A second recess 22 is provided on the bottom surface of the middle counterweight 2, and a second magnetic sheet 31 is provided on the top surface of the small counterweight 3. The second magnetic sheet 31 can be attracted at the second recess 22. By limiting the mass of the small counterweight, it can be attracted by the magnetic sheet and not fall off due to its own weight. When further weight is needed, the bottom surface of the small counterweight can be aligned with the second recess of the middle counterweight for attraction. When it needs to be removed, the small counterweight can be directly taken out of the second recess.

[0032] In a preferred embodiment of this invention, the small counterweight 3 is conical, and the second magnetic piece 31 is disposed on the bottom surface of the small counterweight 3. Making the small counterweight conical facilitates gripping and manipulating it.

[0033] In a preferred embodiment of this invention, the mass of the intermediate counterweight 2 is less than that of the large counterweight 1. The smaller mass of the intermediate counterweight creates a weight gradient among the three counterweights, allowing for more subtle weight variations during counterweighting.

[0034] In a preferred embodiment of this utility model, the large counterweight 1 has a mass of 500g, the medium counterweight 2 has a mass of 300g, and the small counterweight 3 has a mass of 100g.

[0035] In summary, this utility model provides a conveniently installed counterweight block assembly. Through the combination of a large and a medium counterweight block, it achieves the effect of adding counterweight simply by engaging the locking block at the engagement point. To engage, simply push the protrusion of the medium counterweight block into recess one, at which point the locking block is also pushed into the vertical slide. When the locking block is pushed into the horizontal slide, rotating the medium counterweight block causes the locking block and the magnetic plate one to adhere, quickly completing the engagement. A small counterweight block is also included, which can be directly adsorbed into recess two at the bottom of the medium counterweight block. To remove it, simply pry it off; the operation is simple and convenient. Because the three counterweight blocks have different weights, adding counterweight can achieve more precise weight changes than simply stacking counterweight blocks of the same weight.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
