Description

Technical Field

[0001] The utility model relates to the technical field of connecting pieces, in particular to a connecting device for a dummy half-body model and a human face prosthesis. Background Art

[0002] A half-body mannequin is a model device that simulates a real person by covering it with materials such as silicone and rubber and installing it on a skeleton. It usually consists of two parts: the chest cavity and the head and face. It is widely used in various product demonstrations and testing processes. For example, in the verification process of face recognition products, a dummy head model is often needed to verify whether the product can be correctly recognized; in some scenarios, in order to simulate the occlusion of the face by clothing, such as hoods, collars, etc., a half-body mannequin is also needed to facilitate the setting of clothing.

[0003] In the prior art, there are many technical solutions and products for dummy half-body models, all of which involve the simulation of the head, face, neck and chest. For example, Chinese patent CN201821300607.1 discloses a test dummy, which includes a head, a neck and a torso, wherein the head and the torso are connected by a neck, a sensor is installed on the head, the neck is cylindrical, the neck is made of rubber, a metal layer is provided inside the rubber, the metal layer is vulcanized and bonded to the rubber, a joint is clamped at the upper end of the neck cavity, a handle is threadedly connected to the lower end of the neck cavity, a steel cable is connected between the joint and the handle, a transverse through hole is provided on the wall of the neck, a slit is provided on the hole wall of the through hole, and the slit runs through the neck. The purpose is to provide a test dummy that conforms to the physical characteristics of Chinese people and can be tested locally according to needs; for example, Chinese patent CN202120372108.9 discloses a dummy head model, which relates to the field of medical equipment technology, to optimize the dummy head model to a certain extent and realize the simulation of throat test operation. The dummy head model provided by the utility model includes a head body and an oral simulation component; a receiving cavity is provided in the head body, the receiving cavity is located between the upper jaw and the lower jaw of the head body, the oral simulation component is located in the receiving cavity, and the oral simulation component includes the posterior pharyngeal wall, palatopharyngeal arch, uvula, tongue, tonsils and soft palate; the lower jaw of the head body can move relative to the head body in a direction away from or close to the upper jaw of the head body to expose the oral simulation component in the receiving cavity. For this type of technical solution, when its head, face and neck are relatively restored to real people, it can usually be used in the testing process of face recognition products.

[0004] However, in the actual implementation process, the inventors found that due to product needs, it is often necessary to identify different types of dummy head models. For example, when testing products with biometric verification functions, it is necessary to provide a large number of dummy faces for product classification. However, when a half-body model is needed during the test, a large number of half-body models are prone to cause inconvenience in transportation and installation. At the same time, existing dummy head models are usually fixed to the chest cavity using connectors, such as the dummy head model fixture disclosed in Chinese patent CN201310045882.9. This type of connector rarely considers the needs of rapid disassembly and assembly, and cannot be quickly disassembled and restored on site. The above-mentioned many problems have led to the problem of inconvenience in the use of such products. Utility Model Content

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0038] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0039] The utility model includes:

[0040] A connecting device for a dummy half-body model and a human face prosthesis, wherein a mounting plane is provided in the neck region of the dummy half-body model, and the neck region of the human face prosthesis is sleeved in the mounting plane;

[0041] The connecting device includes a first fixing device and a second fixing device;

[0042] The first fixing device is installed on the installation plane and is connected and fixed to the dummy half-body model;

[0043] like Figure 1 As shown, the first fixing device includes a first cylindrical structure 11 and a second cylindrical structure 12, the diameter of the first cylindrical structure 11 is larger than that of the second cylindrical structure 12, and the second cylindrical structure 12 is located above the first cylindrical structure 11;

[0044] A first thread 13 is provided on the side surface of the first cylindrical structure 11;

[0045] like Figure 2 As shown, the second fixing device is fixed at the bottom end of the neck area, the second fixing device is in the shape of a disc, and a first circular groove 21 and a second circular groove 22 which are sleeved in sequence are arranged in the second fixing device;

[0046] The second circular groove 22 is located above the first circular groove 21 , and the inner wall of the first circular groove 21 is provided with a second thread 23 matching the first thread 13 .

[0047] Specifically, in order to solve the problem that the head area of ​​the dummy half-body model in the prior art is relatively fixed and difficult to disassemble, in this solution, the dummy half-body model and the facial prosthesis are separated. Among them, the dummy half-body model refers to the half-body model of the dummy, which includes the shoulder-clavicle and the chest area below, but does not include the neck and the part above. The facial prosthesis refers to the part of the model used to simulate the head, face and neck, which is wrapped with plastic, rubber, silicone and other materials to achieve a similar appearance to a real person. In order to achieve the connection between the two, the dummy half-body model opens an installation plane corresponding to the position of the neck area, and the bottom end of the neck of the facial prosthesis has a certain extension to be inserted into the installation plane, thereby reducing the seam at the connection. In the connection process, in order to solve the problem that the dummy head model in the prior art is relatively fixed and difficult to disassemble, the above-mentioned first fixing device and second fixing device are introduced.

[0048] The first fixing device includes a second cylindrical structure 12, which is located above the first cylindrical structure 11; the second fixing device is provided with a second circular groove 22 located above, the second circular groove 22 is a hollow cylindrical interface, and the inner diameter of the second circular groove 22 matches the outer diameter of the second cylindrical structure 12, so that the second circular groove 22 can be sleeved on the second cylindrical structure 12. When the face prosthesis falls, it is guided and positioned by the second circular groove 22 and the second cylindrical structure 12 that match each other. Subsequently, when the upper surface of the first cylindrical structure 11 abuts against the lower surface of the first circular groove 21, the human face prosthesis is fixed by rotating the human body face so that the first thread 13 and the second thread 23 that match each other are screwed into each other. Since the above process is fixed by screwing in the thread, it can achieve a faster loading and unloading process than the existing fixing pile method.

[0049] In one embodiment, Figure 3 As shown, the number of first threads 13 and second threads 12 is three pairs;

[0050] The first thread 13 and the second thread 23 are rectangular threads, and the crest width of the rectangular thread is the same as the root width of the rectangular thread;

[0051] The crest edge of the rectangular thread is also provided with a chamfer.

[0052] Specifically, in order to achieve a faster installation effect, in this embodiment, the structures of the first thread 13 and the second thread 23 are adjusted to rectangular threads with the same crest width and root width, and the number is controlled to be three pairs, and each pair of threads only wraps around a section of the first cylindrical structure 11. The pitch of this thread is relatively wide compared to the thread with a triangular tooth profile, thereby reducing the number and length of turns wrapped around the first cylindrical structure 11; at the same time, friction fixation is achieved through the larger surface area of ​​the rectangular thread. On this basis, the problem of wear of the rectangular thread is reduced by providing a chamfer on the crest edge.

[0053] In one embodiment, a plurality of screw through holes 14 are distributed on the upper end surface of the first cylindrical structure 11 around the second cylindrical structure 12, and a plurality of screw mounting holes are distributed at positions corresponding to the screw through holes 14 in the mounting plane;

[0054] The first fixing device is fixedly connected to the screw mounting hole by means of a bolt passing through the screw through hole 14 .

[0055] Specifically, in order to achieve a better fixing effect, in this embodiment, a plurality of screw holes 14 are distributed on a circle on the upper end surface of the first cylindrical structure 11 surrounding the second cylindrical structure 12. By screwing corresponding bolts into the screw holes, the first fixing device can be more firmly fixed on the installation plane to reduce shaking.

[0056] In one embodiment, the screw through holes 14 include a first type of screw through holes 141 and a second type of screw through holes 142 ;

[0057] The first type screw through holes 141 and the second type screw through holes 142 are arranged at intervals.

[0058] Specifically, in order to achieve a better fixing effect, in this embodiment, the screw through holes are selected as first-type screw through holes 141 and second-type screw through holes 142 and are arranged at intervals. The first-type screw through holes 141 are used to insert round head screws, and the second-type screw through holes 142 are used to insert flat head screws. The size of the flat head screw is larger than that of the round head screw. The number of screw through holes is 6 in total.

[0059] As an optional implementation, positioning holes 15 are further provided on the distribution circle where the screw through holes 14 are located, which match the positioning marks on the installation plane so that the first fixing device has a correct orientation when installed on the installation plane.

[0060] In one embodiment, the second cylindrical structure 12 is a hollow cylindrical structure that passes through the first fixing device. A positioning protrusion corresponding to the inner diameter of the cylindrical structure is provided on the installation plane to facilitate positioning of the first fixing device on the installation plane.

[0061] In one embodiment, the second circular groove 22 is a cylindrical structure with a diameter smaller than that of the first circular groove 21 , and the second circular groove 22 passes through the second fixing device so that the second cylindrical structure 12 can penetrate therein.

[0062] like Figure 4 As shown, a threaded fixing through hole 24 is provided on the second fixing device at a height corresponding to the second circular groove 22;

[0063] The threaded fastener through hole 24 passes through the side wall of the second fastener to reach the second circular groove 22;

[0064] When the second circular groove 22 is sleeved on the second cylindrical structure 12 , the threaded fastener passes through the threaded fastener through hole and abuts against the second cylindrical structure 12 .

[0065] Specifically, in order to achieve a relatively stable fixing effect, in this embodiment, a threaded fixture through hole 24 is provided on the second fixing device at a height corresponding to the second circular groove 22, and the inner wall of the threaded fixture through hole 24 is processed with threads so that the threaded fixture can be inserted and fixed. When the second circular groove 22 is sleeved on the second cylindrical structure 12, the threaded fixture passes through the threaded fixture through hole and abuts against the second cylindrical structure 12, so that the end face of the threaded fixture and the side wall of the second cylindrical structure 12 are frictionally fixed to prevent the facial prosthesis from shaking or unscrewing.

[0066] In one embodiment, the lower bottom surface of the second circular groove 22 has three third-type screw through holes 25 distributed in a triangular shape, and the lower bottom surface of the neck region has a plurality of screw installation holes distributed in the region corresponding to the third-type screw through holes 25;

[0067] The second circular groove 22 is fixedly connected to the screw mounting hole by a bolt passing through the third type screw through hole 25 .

[0068] Specifically, in order to achieve a better fixing effect, in this embodiment, a plurality of third-type screw through holes 25 are distributed on the concentric circles on the outer side of the second circular groove 22. By screwing the corresponding bolts into the third-type screw through holes 25, the second fixing device can be more firmly fixed at the bottom of the neck area to reduce shaking.

[0069] The above are only preferred embodiments of the present invention, and do not limit the implementation mode and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
