Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
FIG. 1 is a schematic structural diagram of a finger positioning module in the finger positioning device according to an embodiment of the present invention. As shown in fig. 1, the finger positioning module may include a finger rest 1 for carrying a finger; the upper limiting frame 2 is arranged above the finger rest 1 and is used for being matched with the finger rest 1 to fix and position the finger from the upper direction and the lower direction of the finger; and an adjusting guide rail 3 arranged below the finger rest 1, wherein the extending direction of the adjusting guide rail 3 is configured to be along the extending direction of the finger, so as to realize the position adjustment of the finger positioning module along the extending direction. The upper limiting frame 2 is a hollow arch structure, and a gap for a finger to pass through is reserved between the upper limiting frame 2 and the finger rest 1. To further improve the comfort of the user, the surface of the finger rest 1 may be provided with a concave surface for cooperation with the fingers. Through setting up finger rest 1 and last spacing frame 2, place the finger on finger rest 1, utilize last spacing frame 2 and finger rest 1 to compress tightly the finger from two directions about the finger in order to realize the fixed positioning of finger. The fixed positioning of the fingers can be simplified by the matching of the finger support and the upper limiting frame, the efficiency of the fixed positioning is improved, the position adjustment of the finger support and the upper limiting frame can be realized by the adjusting guide rail, and the application range is further improved.
In one embodiment, the upper limiting frame 2 can be disposed above the first joint of the finger carried by the corresponding finger rest 1. After the finger is placed on the finger rest 1, the upper limiting frame 2 compresses the first joint of the finger, so that the finger nail can not move. For example, when the finger positioning device is applied to a nail beautifying device, a finger can be fixed through the finger positioning device, and nail printing operation is carried out on the nail by a printer in the nail beautifying device, so that the nail is ensured to be fixed in the nail printing process.
It should be understood that different relative positions of the upper limiting frame and the finger rest may be selected according to different application scenarios, as long as the relative positions of the upper limiting frame and the finger rest are selected to be capable of being matched with each other to realize fixed positioning of a finger, and the relative positions of the upper limiting frame and the finger rest are not limited in the present invention.
In one embodiment, the module further comprises a lifting device 4 disposed below the finger rest 1, the lifting device 4 being used for providing pressure to the finger rest 1 in the direction of the finger. The supporting device 4 is arranged to provide pressure to the finger support 1 towards the direction of the finger, and the upper limiting frame 2 is matched to realize fixed positioning of the finger.
In a further embodiment, the holding-up means 4 may comprise a self-locking spring 5. The self-locking spring 5 is connected with the finger support 1, and the self-locking spring 5 is driven to act by pressing the finger support 1. When the self-locking spring 5 is in a compressed state, the gap between the finger support 1 and the upper limiting frame 2 is larger. At the moment, after a finger is placed on the finger rest 1, the finger rest 1 is pressed to drive the self-locking spring 5 to move to a release state, and the finger is fixedly positioned between the finger rest 1 and the upper limiting frame 2 by utilizing the elasticity of the self-locking spring 5. After nail printing is finished, the finger holder 1 is pressed to drive the self-locking spring 5 to move to a pressing state, and the finger can be taken out. The self-locking spring 5 can be used for simply realizing the fixed positioning of the fingers on the premise of not needing the assistance of other fingers, so that the positioning operation is simplified, and the working efficiency is improved.
It should be understood that, in the embodiment of the present invention, the elastic positioning mechanism other than the self-locking spring in the embodiment may be selected according to different application scenarios, as long as the selected elastic positioning mechanism can realize fixed positioning of the finger, and the specific type and structure of the elastic positioning mechanism are not limited in the present invention.
FIG. 2 is a schematic structural diagram of an embodiment of the finger positioning device according to the invention. As shown in fig. 2, the finger positioning device may include four finger positioning modules, and the four finger positioning modules are respectively disposed corresponding to the positions of the index finger, the middle finger, the ring finger and the little finger of the user. Finger positioner can set up to an overall structure including four finger location modules according to the position of four fingers of people's forefinger, middle finger, ring finger, little finger, utilizes four finger location modules can realize the fixed positioning of four fingers of single, can realize simultaneously that the first beautiful of four fingers prints, raises the efficiency by a wide margin.
In an embodiment, the finger positioning device further comprises four adjusting rails 3 respectively disposed below the four finger positioning modules, wherein the extending direction of the adjusting rails 3 is configured to be along the extending direction of the user's finger for realizing the position adjustment of the finger positioning module along the extending direction of the user's finger. Because the finger length of different users probably is different, the adjustment of the relative position of each four finger positioning modules can be realized through the adjustment guide rail 3 of each finger positioning module, thereby ensuring that the four finger positioning modules can adapt to different fingers of different users and increasing the application range.
In an embodiment, the finger positioning device further includes a four-finger moving rail 6 disposed below the four finger positioning modules, wherein the extending direction of the four-finger moving rail 6 is configured to be along the extending direction of the fingers of the user, so as to realize the position adjustment of the four finger positioning modules along the extending direction of the fingers of the user. Four finger movable guide rails 6 are arranged below the four finger positioning modules, after the four finger fixing and positioning are completed, the four finger positioning modules can be pushed to move integrally along the four finger movable guide rails 6, the four finger positioning modules can be moved simply, and the relative positions of the four finger positioning modules are fixed.
In a further embodiment, the four-finger moving guide 6 may comprise two parallel guides. Four indicate movable guide 6 sets up to the guide rail of two parallels, prevents that four finger location modules from rocking about on four indicate movable guide 6, can improve the stationarity of four finger location modules on four indicate movable guide 6.
It should be understood that, in the embodiment of the present invention, different numbers of guide rails may be selected according to different application scenarios, as long as the number of the selected guide rails can realize smooth sliding of the four finger positioning modules on the four-finger moving guide rail, and the number of the guide rails is not limited in the present invention.
