Description

Technical Field

[0001] The utility model relates to the human body model field technology, in particular to a combined human body skeleton structure used for human body models. Background Art

[0002] Human models are generally made in a 1:1 ratio to real people. The human model is relatively soft and elastic, and its skin is similar to that of real people. Currently, human models on the market generally consist of a main body and a support frame. The support frame is set inside the main body. The main body is made of silicone material. The main body completely covers the support frame, making the human model soft and elastic.

[0003] In the prior art, the support frames used in the human body models are all integrated cast iron frame structures. Such support frames are mainly composed of multiple transverse rods and multiple longitudinal rods, which only play the role of propping up the main body. The overall hardness and rigidity are very large, and the elasticity is relatively weak, and it cannot provide internal elasticity for the human body model. At the same time, such support frames do not have movable joints, and the various component units are not movable, so that the simulation effect of the human body model is not ideal and cannot meet the needs of use. In addition, the support frame with a cast iron structure is heavy and bulky to carry, which brings inconvenience to carrying.

[0004] Therefore, it is necessary to improve the support frame of the current human body model to improve the simulation degree of the human body model and meet the needs of use. Utility Model Content

[0050] The manufacturing and usage methods of this embodiment are basically the same as those of the aforementioned first preferred embodiment, and the manufacturing and usage methods of this embodiment will not be described in detail here.

[0051] The design focus of the present utility model lies in that: this product is formed by combining an upper torso skeleton, a lower torso skeleton, a pelvic skeleton and two lower limb rods, and the upper torso skeleton, the lower torso skeleton and the pelvic skeleton are all made of rigid plastic injection molding parts. It imitates the human skeleton as a whole. On the premise of meeting the structural strength requirements, the hardness and rigidity are greatly reduced compared with the cast iron structure, and at the same time, it also has better elasticity, which can provide internal elasticity for the human body model. In addition, the pelvic skeleton is hinged to the lower torso skeleton through a first joint member, and the upper end of each lower limb rod is respectively hinged to the left and right sides of the bottom of the pelvic skeleton through a second joint member, so that each component unit can move, thereby making the simulation effect of the human body model better and meeting the usage requirements.
