Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a device for measuring the distance between eyebrows in the T-zone of the face. Background Technology

[0002] In existing technologies, eyebrow distance measurement in the facial T-zone primarily employs a single horizontal ruler. Since eyebrow distance measurement requires considering the relative positions of the nasal bridge midline and the brow ridge, a single ruler cannot accurately locate the three-dimensional coordinates of the facial T-zone. This necessitates repeated adjustments to the tool angle during measurement, resulting in cumbersome operation and significant errors. Furthermore, the ruler only provides horizontal graduations and lacks a midline marker perpendicular to the nasal bridge. Measurement requires visual estimation or manual calculation to determine the midpoint between the eyebrows, making it susceptible to operator experience. Additionally, the nasal alae, a crucial reference point for T-zone measurement, have a naturally curved tip. Traditional tools often use flat or straight markings that cannot conform to the nasal alae's curved surface, leading to slippage or offset during positioning and affecting the stability of the measurement reference. Utility Model Content

[0003] The purpose of this invention is to provide a device for measuring the distance between eyebrows in the T-zone of the face, so as to solve the technical problem of inconvenience in use in the prior art.

[0004] To solve the above problems, the present invention relates to a device for measuring the distance between eyebrows in the T-zone of the face, which adopts the following technical solution:

[0005] This utility model provides a device for measuring the distance between eyebrows in the T-zone of the face, including a main ruler for horizontal setting and a secondary ruler perpendicular to the main ruler. The secondary ruler is longitudinally slidably engaged with the main ruler through a sliding pair, and its relative position with the main ruler is positioned or unlocked by a positioning component. The longitudinal end face of the secondary ruler is recessed in the longitudinal direction with a V-shaped groove matching the shape of the front end of the nose. The vertical surface of the secondary ruler is engraved with a center line segment that is collinear with the center surface of the groove. The vertical surface of the main ruler is engraved with a horizontal segment that is perpendicular to the center line segment.

[0006] Preferably, a silicone layer is adhered to the inner surface of the groove.

[0007] Preferably, a level is provided on the vertical surface of the vernier scale.

[0008] Preferably, the main scale has a slide rail extending through both ends of its longitudinal direction, and the secondary scale is matched and installed in the slide rail, which can slide longitudinally along the slide rail. The vertical surface of the main scale has a screw hole that connects to the slide rail, and the positioning element passes through the screw hole and abuts against the secondary scale to limit the relative position of the main scale and the secondary scale.

[0009] The beneficial effects of this utility model are as follows:

[0010] This invention provides a device for measuring the distance between eyebrows in the T-zone of the face. It includes a main ruler positioned horizontally, differing from existing technologies in that it also includes a secondary ruler perpendicular to the main ruler. The secondary ruler slides longitudinally with the main ruler via a sliding joint, and its relative position to the main ruler is positioned or unlocked by a positioning component. The longitudinal end face of the secondary ruler has a V-shaped groove recessed inwards in the longitudinal direction, matching the shape of the front end of the nose wing. The vertical surface of the secondary ruler is engraved with a centerline segment collinear with the center plane of the groove, and the vertical surface of the main ruler is engraved with a horizontal segment perpendicular to the centerline segment. Based on the natural law that the bridge of the nose is located in the middle of the nose, this device cleverly places the secondary ruler on the bridge of the nose to find the midline between the two eyebrows, thus easily determining the distance between the two eyebrows and the midline.

[0015] To make the technical objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0016] The present invention provides a device for measuring the distance between eyebrows in the T-zone of the face, as shown in the figure. It includes a main ruler 1 for horizontal setting and a secondary ruler 2 perpendicular to the main ruler 1. Both the main ruler 1 and the secondary ruler 2 are long strip-shaped structures.

[0017] The vertical surface of the main scale 1 is laser-engraved with transverse scale segments. The middle section of the main scale 1 has a slide that runs through both ends of its longitudinal direction. The sidewalls of the slide are coated with a wear-resistant nylon coating to reduce the coefficient of friction.

[0018] The auxiliary ruler 2 is matched and set in the slide. The auxiliary ruler 2 can slide back and forth along the slide longitudinally on the main ruler 1 to adjust the relative position of the two. The longitudinal front end of the auxiliary ruler 2 is provided with a V-shaped groove 4 that matches the shape of the nose. The vertical surface of the auxiliary ruler 2 is engraved with a center line segment 5. The center plane of the groove 4 is collinear with the vertical center line segment 5 of the auxiliary ruler 2.

[0019] A threaded hole extending into the sliding body is opened on the vertical surface of the main scale 1, and a positioning screw (positioning element 3) with a locking knob is configured. When the knob is rotated, the front end of the screw abuts against and presses against the secondary scale 2, thereby positioning the main scale 1 and the secondary scale 2.

[0020] Furthermore, a medical-grade silicone layer is adhered to the inner surface of the groove 4, and the surface of the silicone layer is provided with anti-slip texture. A circular bubble level 6 is installed at the vertical upper end of the auxiliary ruler 2.

[0021] Finally, it should be noted that the above embodiments are only for illustration and not for limiting the technical solutions of this utility model. Any equivalent substitutions and modifications or partial substitutions that do not depart from the spirit and scope of this utility model should be covered within the scope of protection of the claims of this utility model.
