Description

Technical Field

[0001] The utility model relates to the technical field of teaching models, in particular to an upper limb muscle model with detachable starting and ending points. Background Art

[0002] In the process of teaching human body structure, in order to make the teaching more intuitive and vivid, it is often necessary to use a simulated human body model. Explanations through human body models can make students' understanding of human body structure more intuitive, which helps to improve teaching efficiency.

[0003] In the teaching of the muscle structure of the human upper limb, an upper limb muscle model is used. The existing muscle model often includes a skeleton part and a muscle part. In order to make the teaching more intuitive, the muscle part and the skeleton part are often detachable, such as the existing commonly used built-in magnet method, that is, magnets are embedded in the skeleton part and the muscle part, so that the muscle part and the skeleton part can attract and fix each other when they are close to each other, and when they need to be separated, the two can be kept away from each other; the detachable magnet method facilitates the disassembly and installation of the muscle part and the skeleton part of the model to a certain extent, but in actual use, due to the limitation of the number and size of the skeleton model and the muscle model, the mutual attraction between the magnets is often not very strong, and the embedded method will also affect the attraction between the magnets, so it is often encountered that the muscle part and the skeleton part are not firmly adsorbed, and the muscle model will fall off if you are not careful, causing damage and bringing inconvenience to use.

[0004] Therefore, a muscle model that is easy to disassemble the muscle and bone parts of the model and can ensure installation stability during installation is a problem that needs to be solved. Utility Model Content

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0022] Embodiments of the present utility model:

[0023] like Figure 1-6 As shown, in the embodiment model, a skeleton model 1 (which may be made of ceramic material) and a muscle model 2 (which may be made of rubber material) are provided, and the skeleton model 1 and the muscle model 2 are detachably connected.

[0024] A first locking mechanism 3 is arranged at the lower end of the skeleton model 1, and a second locking mechanism 4 is arranged at the upper end of the skeleton model 1; wherein a first mounting groove 11 is arranged at the lower end of the skeleton model 1, and the first locking mechanism 3 is glued and fixedly installed in the first mounting groove 11; a second mounting groove 12 is arranged at the upper end of the skeleton model 1, and the second locking mechanism 4 is glued and fixedly installed in the second mounting groove 12.

[0025] A mechanism box 31 is provided in the first locking mechanism 3, a guide rod 32 is provided between the front and rear sides of the mechanism box 31, a slide plate 33 is slidably installed through the guide rod 32, wherein a connecting hole 331 is provided on the slide plate 33, the connecting hole 331 is slidably connected with the guide rod 32, and sliders 332 are provided on both sides of the slide plate 33, and correspondingly, slide grooves 37 are provided on the left and right sides of the mechanism box 31, and the slide grooves 37 are slidably matched with the sliders 332; a spring 34 is provided between the slide plate 33 and the rear side of the mechanism box 31, wherein the spring 34 is sleeved on the guide rod 32 and is in a compressed state; a hand-held portion 36 is provided on one side of the slide plate 33, a first hook 35 is provided on the slide plate 33, and a first hanging groove 21 is provided at a corresponding position on the muscle model 2, and the first hanging groove 21 is matched with the first hook 35.

[0026] A connecting block 41 is provided in the second locking mechanism 4, and the connecting block 41 is glued and fixedly connected to the second mounting groove 12. A second hook 42 is connected to the connecting block 41, and a second hanging groove 22 is provided at a corresponding position on the muscle model 2, and the second hanging groove 22 cooperates with the second hook 42.

[0027] In this embodiment, the openings of the first hook 35 and the second hook 42 are arranged in opposite directions, wherein the opening of the first hook 35 is arranged upward, and the opening of the second hook 42 is arranged downward, and the spring 34 is arranged at a position opposite to the direction of the first opening.

[0028] The principle of this utility model is:

[0029] When the utility model is in use, the muscle model 2 and the skeleton model 1 can be installed and disassembled, so that the muscle model 2 can be removed for observation, which is beneficial to improving the teaching effect; at the same time, after the muscle model 2 and the skeleton model 1 are installed, the muscle model 2 is installed stably and will not fall off easily, thereby ensuring the stability of use.

[0030] When disassembling the muscle model 2, the hand-held portion 36 is pushed downward by hand, so that the first hook 35 and the first hanging groove 21 are separated from each other. At this time, the muscle model 2 is held downward to separate the second hook 42 from the second hanging groove 22, and the muscle model 2 can be disassembled.

[0031] When installing the muscle model 2, the first hanging groove 21 is matched with the first hook 35, and the muscle model 2 is pushed downward with force. At this time, the muscle model 2 drives the slide plate 33 to move downward. When the slide plate 33 moves to a certain position, the second hanging groove 22 can be matched with the second hook 42 in space. At this time, stop applying force. Under the action of the spring 34, the muscle model 2 moves upward and makes the second hanging groove 22 match with the second hook 42, thereby realizing the installation of the muscle model 2. During the process, the setting of the spring 34 can realize the tight support of the muscle model 2 and will not fall off easily.
