Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of nail clippers, in particular to a locking structure and a nail clipper with the locking structure. Background Art
[0002] At present, there are many types of nail clippers on the market. Their structures include a pliers head, two handles, a reset member between the handles, or a spring sheet is provided on the inner side of the two handles for resetting the handles after clamping. However, using the spring sheet to reset the two handles will result in insufficient resetting elasticity of the handles, and even cause the two handles to open excessively, which is easy to pinch the user's fingers. Moreover, when the nail clippers are not in use, the pliers heads are opened, and the sharp pliers mouths are easy to scratch when not paying attention, which poses a safety hazard.
[0003] In 2020, the inventor proposed a pair of nail groove pliers with a closed rotary locking function, Chinese patent publication number CN213758496U. The above patent solves the problem of excessive opening and closing of the pliers head through a closed rotary locking structure. However, during use, the rotary locking part easily rotates synchronously with the up and down opening and closing of the pliers body, causing the locking protrusion to accidentally enter the special-shaped locking groove, thereby increasing the difficulty of operation.
[0004] Therefore, the present invention proposes a locking structure and a nail clipper with the locking structure to solve the problem that the locking protrusion accidentally enters the special-shaped locking groove. Utility Model Content

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.
[0034] Example 1
[0035] refer to Figure 1-3 As shown, a locking structure includes: a travel channel 11, a limiting post 12, and a locking mechanism 13. The travel channel 11 is an arc-shaped structure, the specific arc being determined by actual needs. A locking chamber 110 is provided at one end of the travel channel 11; the limiting post 12 is positioned within the travel channel 11 and moves within the travel channel 11. Since the travel channel 11 is closed at both ends, the movement range of the limiting post 12 is limited, effectively avoiding the problem of excessive opening and closing.
[0036] The locking mechanism 13 in this embodiment includes a pulley 131, a pulley shaft 132, a locking column 133, and a limit member 134; wherein the locking column 133 is placed on one side of the pulley 131 and placed in the travel channel 11. The pulley 131 rotates around the pulley shaft 132 and drives the locking column 133 to move into or out of the locking chamber 110.
[0037] The locking post 133 in this embodiment is offset from the center of the pulley 131 . Therefore, when the pulley 131 rotates, the locking post 133 will be displaced to a certain extent. The displacement is just enough to move the locking post into or out of the locking chamber 110 .
[0038] In particular, the limiting member 134 in this embodiment is placed on the pulley 131 and does not protrude from the surface of the pulley 131, and limits the rolling of the locking mechanism 13 by magnetic attraction. Generally, the limiting member 134 is a rubidium magnet. Since the rubidium magnet has strong permanent magnetic properties, it has good stability and can be used for a long time.
[0039] In this embodiment, the pulley 131 is circular in shape, and the pulley shaft 132 is located at the center of the pulley 131. When the pulley 131 is rotated, the locking column 133 also rotates around the pulley shaft 132 and drives the locking column 133 to move into or out of the locking chamber 110.
[0040] In this embodiment, there is another technical solution. The pulley 131 is cam-shaped, and the pulley shaft 132 is located at an eccentric position of the pulley 131. When the pulley 131 is rotated, the locking column 133 rotates around the pulley shaft 132 and drives the locking column 133 to move in or out of the locking chamber 110.
[0041] In this embodiment, anti-skid stripes 135 are provided on the outer periphery of the pulley 131 . The anti-skid stripes 135 can increase friction, and the rotation of the pulley 131 can be achieved conveniently and quickly.
[0042] Example 2
[0043] refer to Figure 1-6 As shown, a nail clipper with a locking structure comprises: a first jaw part 100, a second jaw part 200, and the locking structure 300 in embodiment 1;
[0044] Specifically, the front ends of the first jaw part 100 and the second jaw part 200 are rotatably connected to each other through a connecting assembly 400, the travel channel 11 is placed on the first jaw part 100, the limit column 12 is placed on the second jaw part 200, and the locking mechanism 13 is placed in the cavity 500 of the second jaw part 200, and its end face protrudes from the cavity 500 to facilitate the rotation of the sliding operating pulley 131.
[0045] It is worth noting that the limiting member 134 in this embodiment is located on the opposite side of the locking column 133 .
[0046] In order to better achieve magnetic fixation of the limiter 134 , at least one magnetic point is provided in the chamber 500 , wherein the first magnetic point 501 is located at the relative position of the limiter 134 when the locking column 133 is in the locking chamber 110 .
[0047] In this embodiment, there are two magnetic points, wherein the second magnetic point 502 is located at a position relative to the limiting member 134 when the locking column 133 moves out of the locking chamber 110 .
[0048] The working method of this embodiment is further described below with a specific example:
[0049] When the first jaw part 100 and the second jaw part 200 are in a relatively closed state, the locking column 133 is in the locking chamber 110. At this time, the limit member 134 and the first magnetic attraction point 501 are in an attracted state. Since the limit member 134 is made of a neodymium magnet, in a general small-amplitude vibration environment, such as when placed in a bag or pocket, the limit member 134 and the first magnetic attraction point 501 will not be opened, the pulley 131 will not rotate, and the first jaw part 100 and the second jaw part 200 are in a relatively closed state.
[0050] When it is needed, under the action of external force, the pulley 131 is rotated, the magnetic attraction effect between the limit member 134 and the first magnetic attraction point 501 is destroyed, the limit member 134 and the first magnetic attraction point 501 are displaced, and the locking column 133 rotates around the pulley shaft 132, and drives the locking column 133 to move out of the locking chamber 110. At this time, the first jaw 100 and the second jaw 200 move relative to each other around the connecting assembly 400 to achieve nail trimming.
[0051] Because this embodiment also includes a second magnetic attraction point 502, when the locking post 133 moves out of the locking chamber 110, the stopper 134 and the second magnetic attraction point 502 engage with each other, thereby ensuring that the locking mechanism 13 remains fixed within the chamber 500. The upward and downward opening and closing of the first and second jaws 100, 200 does not cause the pulley 131 to rotate, thereby preventing the locking post 133 from accidentally entering the locking chamber 110.
[0052] When not in use, the first jaw part 100 and the second jaw part 200 are pressed and placed in a relatively closed state. Under the action of external force, the pulley 131 is rotated, and the magnetic attraction effect between the limit member 134 and the second magnetic attraction point 502 is destroyed. The limit member 134 and the second magnetic attraction point 502 are displaced, and the locking column 133 rotates around the pulley shaft 132 and drives the locking column 133 to move into the locking chamber 110. At the same time, the limit member 134 and the first magnetic attraction point 501 are attracted to each other, and the first jaw part 100 and the second jaw part 200 maintain a relatively closed state.
