Description

Technical Field

[0001] This utility model relates to the field of cleaning device mannequin technology, specifically to a mannequin that is easy to assemble. Background Technology

[0002] Human mannequins are widely used in clothing displays, art education, photography props, and other scenarios. Their core function is to simulate the human body to present clothing patterns or assist in creation. To facilitate the assembly and disassembly of human mannequins, nuts are usually pre-embedded in the mannequin's body and bolts are installed on the arm parts. When assembling or disassembling, simply swing the arm parts to the appropriate position, then connect the bolts and nuts with threads, and finally tighten the bolts.

[0003] However, this type of disassembly and assembly structure relies heavily on rigid connectors such as bolts and nuts to connect the arms to the body. Therefore, when adjusting the rotation angle of the arms, the bolts must be loosened manually first, and then tightened again after the target angle is reached to fix it. The whole process is cumbersome and time-consuming, making it unsuitable for scenarios such as clothing exhibitions and photography shoots where frequent posture adjustments are required. Therefore, there is an urgent need for a mannequin that can quickly adjust the swing angle of the arms without having to loosen the bolts beforehand. Utility Model Content

[0004] The purpose of this utility model is to design a human mannequin that is easy to assemble and does not have at least one of the disadvantages mentioned above.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a mannequin that is easy to assemble, comprising a body and an arm, and further comprising a first support fixed to the body, a second support fixed to the arm, and a rotating component rotatably connected inside the first support; the rotating component has an elastic external toothed ring at one end away from the first support, and an elastic internal toothed ring that meshes with the elastic external toothed ring is fixed to the first support; the rotating component has an end away from the elastic external toothed ring that is detachably connected to the second support; when the arm is subjected to a circumferential force greater than its own weight, the elastic external toothed ring and the elastic internal toothed ring undergo elastic deformation while the elastic external toothed ring rotates.

[0006] Furthermore, both the arm component and the body body are provided with mounting cavities, and both the first support base and the second support base are provided with fixing plates, which are fixedly connected to the mounting cavities by bolts.

[0007] Furthermore, a through hole is provided on the mounting cavity of the arm component, and the through hole penetrates the outer side wall of the arm component.

[0008] Furthermore, the second support base is provided with a support column, and the rotating component includes a rotating shaft rotatably connected to the first support base, an elastic external gear ring fixed to the end of the rotating shaft and located near the body body, and a square shaft fixed to the end of the rotating shaft opposite to the elastic external gear ring. The square shaft is detachably connected to the support column, and the support column is provided with a square hole that mates with the square shaft.

[0009] Furthermore, an internal threaded hole is fixedly connected to the end of the square shaft, a limiting plate is fixedly connected to the square shaft, and a locking bolt is threadedly connected to the internal threaded hole. When the locking bolt is tightened, the limiting plate is tightly attached to the end of the support column.

[0010] Furthermore, a first washer is fitted onto the locking bolt. When the locking bolt is tightened, the first washer is in close contact with the end of the support column. At this time, the first washer and the limiting plate clamp the support column, thereby allowing the square shaft to be installed on the support column.

[0011] Furthermore, the locking bolt is a wing bolt.

[0012] Furthermore, a plurality of second gaskets are sleeved on the square shaft between the limiting plate and the support column.

[0013] Furthermore, the rotating shaft is rotatably connected to the first support base via a bearing.

[0014] Furthermore, the elastic external gear ring is provided with a plurality of dividing slots, which divide the elastic external gear ring into a plurality of blocks.

[0015] Furthermore, an end cap is detachably connected to the end of the through hole, and the outer wall of the end cap smoothly transitions with the outer wall of the arm component.

[0016] Furthermore, the tooth profiles of both the elastic outer tooth ring and the elastic inner tooth ring are hemispherical. During non-rotational adjustment, the spherical surface of one outer tooth of the elastic outer tooth ring abuts against the spherical surfaces of two adjacent inner teeth of the elastic inner tooth ring.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: when it is necessary to adjust the swing angle of the arm component, it is only necessary to directly rotate the arm component and cause the elastic outer tooth ring and the elastic inner tooth ring to undergo elastic deformation; when the arm component is adjusted to the appropriate position, it can be loosened to achieve the adjustment of the arm component; therefore, this utility model eliminates the need to frequently tighten the bolts when adjusting the angle of the arm component in the past; thus, it makes the operation simple and reduces the time consumption; making it more suitable for scenarios such as clothing exhibitions and photography shoots that require frequent posture adjustments.

[0025] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description is provided in conjunction with the accompanying drawings and preferred embodiments, based on the specific implementation methods, structure, features and effects of this utility model.

[0026] Example: Please refer to Figures 1-5An easily assembled mannequin includes a body body 1 and an arm 2, a first support 4 fixed to the body body 1, a second support 6 fixed to the arm 2, and a rotating component 12 rotatably connected inside the first support 4. The rotating component 12 has an elastic external toothed ring 8 at its end facing away from the first support 4, and an elastic internal toothed ring 15 fixed to the first support 4 to mesh with the elastic external toothed ring 8. The end of the rotating component 12 facing away from the elastic external toothed ring 8 is detachably connected to the second support 6. When the arm 2 is subjected to a circumferential force greater than its own weight, the elastic external toothed ring 8 and the elastic internal toothed ring 15 undergo elastic deformation, and the elastic external toothed ring 8 rotates simultaneously, thus preventing the arm 2 from rotating due to its own weight. Both the elastic external toothed ring 8 and the elastic internal toothed ring 15 can be made of nitrile rubber or polyurethane elastomer, etc., to achieve elastic deformation.

[0027] Therefore, when it is necessary to adjust the swing angle of the arm component 2, it is only necessary to directly rotate the arm component 2 to cause the elastic outer tooth ring 8 and the elastic inner tooth ring 15 to undergo elastic deformation. When adjusted to the appropriate position, it can be released. This eliminates the need to frequently tighten the bolts when adjusting the angle of the arm component 2 in the past, thus making the operation simple and reducing the time consumption. This makes it more suitable for scenarios such as clothing exhibitions and photography shoots that require frequent posture adjustments.

[0028] In one embodiment, the teeth of both the elastic external gear ring 8 and the elastic internal gear ring 15 are hemispherical. During non-rotational adjustment, the spherical surface of one external tooth in the elastic external gear ring 8 abuts against the spherical surfaces of two adjacent internal teeth in the elastic internal gear ring 15. When the arm component 2 is not subjected to external force, the elastic external gear ring 8 and the elastic internal gear ring 15 will be in a relatively static state. When the arm component 2 is subjected to a circumferential force greater than its own weight, both the external and internal teeth will undergo elastic deformation, thereby causing the external teeth to rotate relative to the internal teeth, thus ensuring the adjustable rotation angle of the arm component 2. Since both the external and internal teeth are spherical, it is beneficial for the external teeth to slide, thereby improving the service life of the external and internal teeth. The elastic external gear ring 8 is provided with several dividing slots 9, thereby dividing the elastic external gear ring 8 into several pieces, which facilitates the elastic deformation of the elastic external gear ring 8.

[0029] In one embodiment, both the arm component 2 and the body body 1 are provided with mounting cavities. The first support base 4 and the second support base 6 are each provided with a fixing plate 10, which is fixed to the mounting cavity by bolts, thereby enabling independent standardized production of the first support base 4 and the second support base 6. The second support base 6 is provided with a support column. The rotating component 12 includes a rotating shaft 11 rotatably connected to the first support base 4, an elastic external gear ring 8 fixed to the end of the rotating shaft 11 and located near the body body 1, and a square shaft 5 fixed to the end of the rotating shaft 11 facing away from the elastic external gear ring 8. The rotatable connection can be implemented using… The bearing 13 is connected in the form of a detachable connection; the square shaft 5 is detachably connected to the support column and the support column is provided with a square hole that mates with the square shaft 5; thus, the arm 2 and the elastic external gear ring 8 are rotated synchronously to prevent slippage. At this time, the arm 2 is rotated, thereby driving the second support seat 6 to rotate, which in turn drives the square shaft 5 and the rotating shaft 11 to rotate, and finally drives the elastic external gear ring 8 to rotate. When the force on the elastic external gear ring 8 and the elastic internal gear ring 15 is greater than the force that causes them to elastically deform, the elastic external gear ring 8 and the elastic internal gear ring 15 undergo elastic deformation, thereby realizing the relative rotation of the elastic external gear ring 8 and the elastic internal gear ring 15.

[0030] The square shaft 5 has an internally threaded hole fixed to its end, and a limiting plate 7 is fixed to the square shaft 5. A locking bolt 14 is threaded into the internally threaded hole. When the locking bolt 14 is tightened, the limiting plate 7 is pressed tightly against the end of the support column, thus achieving a detachable connection between the square shaft 5 and the support column. When the arm component 2 needs to be installed on the body body 1, the square shaft 5 needs to be inserted into the square hole, and then the locking bolt 14 is inserted into the internally threaded hole and tightened, thus achieving the connection between the arm component 2 and the body body 1. At this time, the elastic external gear ring 8 moves with the arm component 2... The mechanism rotates as it rotates; the locking bolt 14 is a wing bolt, which facilitates the tightening of the locking bolt 14; a through hole 3 is provided on the mounting cavity of the arm piece 2, which penetrates the outer wall of the arm piece 2, thereby facilitating the tightening of the locking bolt 14; in addition, a detachable end cap can be provided to block the outlet of the through hole 3. The detachable method can be a snap-fit, and the outer wall of the end cap and the outer wall of the arm piece 2 are smoothly transitioned, thereby ensuring aesthetics and preventing the clothing from collapsing at this point, which would affect the display of the clothing.

[0031] In one embodiment, a first washer is fitted on the locking bolt 14. When the locking bolt 14 is tightened, the first washer is in close contact with the end of the support column. At this time, the first washer and the limiting plate 7 clamp the support column, thereby allowing the square shaft 5 to be installed on the support column, thus further ensuring the connection strength between the arm component 2 and the square shaft 5. Several second washeres are fitted on the square shaft 5 between the limiting plate 7 and the support column to facilitate the adjustment of the distance between the arm component 2 and the body body 1.

[0032] Working principle: When it is necessary to adjust the swing angle of arm 2, simply rotate arm 2 to cause elastic deformation of the elastic outer toothed ring 8 and the elastic inner toothed ring 15; when arm 2 is adjusted to the appropriate position, release to achieve adjustment of arm 2; therefore, this utility model eliminates the need to frequently tighten bolts when adjusting the angle of arm 2 in the past; thus, it simplifies operation, reduces time consumption, and makes it more suitable for scenarios such as clothing exhibitions and photography shoots that require frequent posture adjustments.
