Description

Technical Field

[0001] The utility model relates to the technical field of forehead supports of skin scanners, in particular to a pullable multi-point fixed forehead support device. Background Technique

[0002] A skin scanner is a medical device based on the principle of optics for observing and analyzing skin conditions. With the increasingly wide application of various advanced two-dimensional and three-dimensional skin scanners, they are more and more accepted by beauty salons, clinicians and patients. A more comfortable photographing and human-computer experience is particularly important in the industry competition. During the use of a skin scanner, it needs to be used in conjunction with a corresponding forehead support structure to provide a better wearing experience for users;

[0003] However, among the existing forehead supports of skin scanners, the common methods are the scheme of pressing against the forehead at two points or the scheme of using a fixed hair hoop to press against the forehead. Both of these two schemes have the drawback of limited applicability and need to be used in conjunction with a chin support, which conflicts with the scenario of needing to photograph neck wrinkles; moreover, the scheme of pressing against the forehead at two points will have partial occlusion of the forehead and requires wearing a hair hoop additionally, and the operation is not convenient. In addition, most of the existing forehead supports of skin scanners are installed between the skin scanner and the skin scanner through screws, and the disassembly and assembly operations are relatively inconvenient. For example, the above-listed comparative patents have this problem;

[0004] Therefore, we propose a pullable multi-point fixed forehead support device to solve the above problems. Content of the Utility Model

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1-5 , the present invention provides the following technical solutions.

[0030] Embodiment 1: In order to solve the problems existing in the prior art in the forehead support of the existing skin scanner, the common methods are the two-point forehead pressing scheme or the fixed hair hoop pressing scheme. Both of these two schemes have the disadvantages of application limitations and need to be used in conjunction with a chin support, which conflicts with the scenarios where neck wrinkles need to be photographed; and the two-point forehead pressing scheme will have partial occlusion of the forehead and requires wearing a hair hoop separately, which is not convenient to operate. Therefore, in this embodiment, through the following technical solutions, a retractable multi-point fixed forehead support device is provided, which is provided with a forehead support base 1, a forehead support telescopic bracket 2, a head fixing bracket 5 and a silicone pad 7. The lower end of the forehead support telescopic bracket 2 is fixed to the head fixing bracket 5 through a countersunk head fixing screw 6, and a limit post 4 is adhesively provided at the edge of the lower end of the head fixing bracket 5 through double-sided tape. Through the setting of the silicone pad 7, the comfort can be improved when contacting the human body during use. According to the actual use requirements, by pulling the forehead support telescopic bracket 2 up or down, the forehead support telescopic bracket 2 slides between the forehead support base 1, and both the left and right sides of the upper end of the forehead support telescopic bracket 2 are fixedly connected with limit posts 4. The forehead support telescopic bracket 2 drives the limit posts 4 to slide in the limit groove 8, and the forehead support telescopic bracket 2 drives the head fixing bracket 5 to telescopically move at the lower end of the forehead support base 1 to adjust the position of the head fixing bracket 5;

[0031] When adjusted to the corresponding position, by rotating the ball screw 3 threadedly connected to the middle of the upper end of the forehead support telescopic bracket 2, and at the same time, fixing holes 9 are equidistantly arranged on the front side of the forehead support base 1. The ball screw 3 moves backward and is inserted into the fixing hole 9 at the corresponding position, thereby realizing the limit between the forehead support telescopic bracket 2 and the forehead support base 1, positioning the head fixing bracket 5 at the corresponding position below the forehead support base 1. The whole set of structures is based on the forehead support base 1, and the whole set of structures is assembled on the forehead support base 1. The head is fixed by three places of silica gel to position the head, and the entire forehead can be exposed, which is convenient for photographing the forehead. If there is a need for a scenario, the thickness of the silica gel pad 7 can also be adjusted to be close to the head to achieve four-point fixation of the head.

[0032] Embodiment 2: Most of the existing forehead supports of skin scanners are installed with the skin scanner through screws, and the disassembly and assembly operations are relatively inconvenient. Therefore, by providing an installation rod 11, an inner side plate 12, an outer side plate 13, a pull ring 14, a fixing cap 15 and a limiting plate 16, the installation rod 11 is slidably connected in the through hole 10. The inner side of the installation rod 11 is fixedly connected with the inner side plate 12, and the outer side of the installation rod 11 is fixedly connected with the outer side plate 13. The middle part of the outer side plate 13 is fixedly connected with the pull ring 14. The outer surface of the installation rod 11 is threadedly connected with a fixing cap 15 for locking, and the limiting plate 16 is fitted on the outer side surface of the upper end of the forehead support base 1, and the limiting plate 16 is snap-connected with the skin scanner. Combined with the attached Figure 5 shown in the specification, by rotating the fixing cap 15 threadedly connected to the outer surface of the installation rod 11, the fixing cap 15 moves outward and disengages from the forehead support base 1, thereby loosening the limit between the installation rod 11 and the forehead support base 1. Then, by pulling the pull ring 14 inward, the pull ring 14 drives the installation rod 11 to slide in the through hole 10 through the outer side plate 13. At this time, the installation rod 11 pushes the inner side plate 12 to move. The upper end of the inner side plate 12 is fixedly connected with the limiting plate 16, and the inner side plate 12 drives the limiting plate 16 to disengage from the skin scanner, so as to remove the forehead support base 1 from the skin scanner, which is convenient for disassembly and assembly operations and can be completed without using bolts and other tools, and is very convenient to use.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
