[0021] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

[0022] Please refer to Figures 1 to 4 A hinged rotating weight includes a first counterweight 1, a second counterweight 2 and a hinge structure, one side of the first counterweight 1 is connected to the second counterweight 2 through a hinge structure, and the other side of the first counterweight 1 is detachably connected to the second counterweight 2.

[0023] From the above description, it can be seen that the beneficial effects of the present invention are: a hinge structure is used as the hinge structure of the first counterweight 1 and the second counterweight 2. Compared with the integral hinge structure of the traditional one-piece injection-molded weight, it has low requirements on material toughness, is not prone to fatigue failure due to repeated rotation, and has a long service life; at the same time, the hinge structure is used as a detachable structure to cooperate with the detachable connection on the other side of the first counterweight 1 and the second counterweight 2, so that the two counterweights can be detached and separated, and the counterweights can be replaced separately. When one of the counterweights fails due to one-piece injection molding, the other counterweight will not be scrapped at the same time.

[0024] Furthermore, the hinge structure includes a rotating shaft 3 and a rotating seat 4. The rotating shaft 3 is provided on one side of the first counterweight block 1, and the rotating seat 4 is provided on one side of the second counterweight block 2. The rotating shaft 3 is rotatably provided in the rotating seat 4.

[0025] As can be seen from the above description, the hinge structure assembled between the first counterweight 1 and the second counterweight 2 is formed by the rotational cooperation between the rotating shaft 3 and the rotating seat 4 .

[0026] Furthermore, a rotation slot 41 is provided on the rotation seat 4 , and an opening of the rotation slot 41 faces away from the surface of the second counterweight 2 .

[0027] As can be seen from the above description, the opening design of the rotating groove 41 allows the rotating shaft 3 to be pressed into the rotating groove 41 from the open opening of the rotating groove 41 when assembling the rotating shaft 3, thereby quickly achieving the assembly of the rotating shaft 3 with the rotating shaft 3.

[0028] Furthermore, the opening of the rotation slot 41 is inclined toward the surface of the second counterweight 2 and away from the rotation shaft 3 .

[0029] From the above description, it can be seen that the inclined setting of the opening direction of the rotating groove 41 provides guidance on the one hand, and on the other hand can avoid interference between the structure on the other side of the first counterweight 1 and the second counterweight 2 during the movement of the first counterweight 1 when the opening direction of the rotating groove 41 is at certain angles, such as perpendicular to the surface of the second counterweight 2.

[0030] Furthermore, a portion of the rotating seat 4 on the side where the rotating groove 41 opens is obliquely connected to the surface of the second counterweight 2 to form a reinforcement seat 42 .

[0031] It can be seen from the above description that the support strength of the rotating base 4 is improved by the reinforcement base 42 obliquely connected to one side of the rotating base 4.

[0032] Furthermore, a support seat 31 is connected between one end of the rotating shaft 3 and the first counterweight 1 , and there is a gap between the rotating shaft 3 and the first counterweight 1 .

[0033] It can be seen from the above description that the rotating shaft 3 is lifted by the support base 31 so that there is enough space between the rotating shaft 3 and the rotating base 4 for rotation.

[0034] Furthermore, support seats 31 are connected between the two ends of the rotating shaft 3 and the first counterweight 1 .

[0035] From the above description, it can be seen that the design of providing support seats 31 at both ends of the rotating shaft 3 can improve the connection strength between the rotating shaft 3 and the first counterweight 1. At the same time, after the rotating shaft 3 is pressed into the rotating groove 41 of the rotating seat 4, the support seats 31 can limit the rotation at both ends of the rotating groove 41 in the length direction.

[0036] Furthermore, a mounting groove is provided on the portion of the first counterweight 1 corresponding to the rotating shaft 3, and the rotating shaft 3 is disposed in the mounting groove.

[0037] It can be seen from the above description that the design of the mounting groove allows the rotating shaft 3 to be arranged in a hidden manner, and at the same time the mounting groove can provide a rotation space for the rotating shaft 3 to rotate with the rotating seat 4 .

[0038] Furthermore, the first counterweight 1 and the second counterweight 2 both include a shell 11 and a cover plate 12, the shell 11 is provided with an opening, a positioning hole 111 is provided in the shell 11, the cover plate 12 is covered at the opening of the shell 11, and the cover plate 12 is provided with a positioning column 121 corresponding to the positioning hole 111; the positioning column 121 is interference fit with the positioning hole 111.

[0039] From the above description, it can be seen that the first counterweight block 1 and the second counterweight block 2 both adopt a fillable structural design, by filling the counterweight structure inside the shell 11 and then closing the opening of the shell 11 through the cover plate 12; the positioning column 121 of the cover plate 12 is matched with the positioning hole 111 of the shell 11, and the cover plate 12 and the shell 11 can be quickly positioned and matched; the interference fit of the positioning column 121 and the positioning hole 111 is adopted to realize the anti-detachment connection between the cover plate and the shell.

[0040] Example 1:

[0041] like Figures 1 to 4As shown, the hinged rotating weight of this embodiment includes a first counterweight block 1, a second counterweight block 2 and a hinge structure. One side of the first counterweight block 1 is connected to the second counterweight block 2 through a hinge structure, and the other side of the first counterweight block 1 is detachably connected to the second counterweight block 2.

[0042] The hinge structure includes a rotating shaft 3 and a rotating seat 4. The rotating shaft 3 is provided on one side of the first counterweight 1, and the rotating seat 4 is provided on one side of the second counterweight 2. The rotating shaft 3 is rotatably mounted within the rotating seat 4. The rotating seat 4 is provided with a rotating groove 41, the opening of which faces away from the surface of the second counterweight 2. Specifically, the opening of the rotating groove 41 is inclined relative to the surface of the second counterweight 2 and away from the rotating shaft 3. The portion of the rotating seat 4 on the side of the rotating groove 41 opening is obliquely connected to the surface of the second counterweight 2 to form a reinforcement seat 42.

[0043] A support base 31 is connected between one end of the rotating shaft 3 and the first counterweight 1, with a gap between the rotating shaft 3 and the first counterweight 1. In this embodiment, support bases 31 are connected between both ends of the rotating shaft 3 and the first counterweight 1. A groove is provided on the portion of the first counterweight 1 corresponding to the rotating shaft 3 to provide sufficient rotational space.

[0044] The first counterweight 1 and the second counterweight 2 each include a housing 11 and a cover 12. The housing 11 has an opening, a positioning hole 111 is provided in the housing 11, and the cover 12 covers the opening of the housing 11. The cover 12 has positioning posts 121 corresponding to the positioning holes 111. The positioning posts 121 are interference-fitted with the positioning holes 111, ensuring a tight fit between the cover 12 and the housing 11.

[0045] The shaft 3, the support seat 31 and the housing 11 can be detachably connected, such as plug-in, to facilitate component replacement. The rotating shaft 3, the support seat 31 and the housing 11 are injected at one time during processing. Plastic molding not only improves the bearing performance of the shaft 3, but also simplifies the subsequent assembly process.

[0046] The cover plate 12 is provided with an assembly groove for the hose to pass through, and the assembly groove is provided with a plurality of pressing protrusions for preventing the hose from slipping.

[0047] In the detachable connection design of the first counterweight 1 and the second counterweight 2, a slot 13 is provided on the other side of the first counterweight 1, and a hook 21 is provided on the side of the second counterweight 2 corresponding to the slot 13. A lifting plate is provided corresponding to the hook 21 for operating the slot 13 to separate from the hook 21.

[0048] Example 2

[0049] The difference between the second embodiment and the first embodiment is that a mounting groove is provided in the portion of the first counterweight 1 corresponding to the rotating shaft 3, and the rotating shaft 3 is disposed within the mounting groove. The mounting groove design of the first counterweight 1 ensures that the rotating shaft 3 does not directly protrude from the first counterweight 1 during assembly. Therefore, there is no need to consider the issue of making way for the protruding rotating shaft 3 when assembling the first counterweight 1.

[0050] To sum up, the hinged rotating weight provided by the utility model adopts a hinge structure as the hinge structure of the first counterweight block and the second counterweight block. Compared with the integral hinge structure of the traditional one-piece injection-molded weight block, it has low requirements on material toughness, is not prone to fatigue failure due to repeated rotation, and has a long service life. At the same time, the hinge structure is a detachable structure that cooperates with the detachable connection on the other side of the first counterweight block and the second counterweight block, so that the two counterweight blocks can be detached and separated, and the counterweight blocks can be replaced separately. When one of the counterweight blocks fails due to one-piece injection molding, the other counterweight block will not be scrapped at the same time.
