DETAILED DESCRIPTION

[0035] The following embodiments are provided to further explain and supplement the present invention and do not constitute any limitation to the present invention.

[0036] like Figures 1 to 7 As shown, the main point of the male buckle 10 of the present invention is that a tapping portion 12 is provided thereon, which allows the connecting belt 30 to be extended in different directions, thereby facilitating connection and playing a tapping role.

[0037] The male buckle 10 is used to be detachably connected with the female buckle 20. The male buckle 10 and the female buckle 20 are respectively connected to the connecting belt 30. Through the detachable connection between the male buckle 10 and the female buckle 20, the connecting belt 30 can be connected together or separated.

[0038] The male buckle 10 is provided with a base portion 11 and a branch portion 12. The base portion 11 is the main structure of the male buckle 10 that supports other structures, and its shape is not limited. Generally, the base portion 11 is a block structure with a certain volume.

[0039] The branching portion 12 is fixedly connected to the base portion 11 or formed integrally. Preferably, the branching portion 12 is formed integrally with the base portion 11.

[0040] The branching portion 12 is configured to be used to pass the connecting belt 30 and force the connecting belt 30 to pass therethrough at least in a first direction X and a second direction Y, and the first direction X and the second direction Y are not located on the same straight line, so that the connecting belt 30 is arranged along different directions. In this way, the connecting belt 30 with a single direction can be branched along different directions.

[0041] In some embodiments, the first direction X and the second direction Y are inclined, and the angle between them can be set as needed, which can be an acute angle, an obtuse angle, or a right angle. In this embodiment, the angle between the first direction X and the second direction Y is an acute angle.

[0042] In some embodiments, the first direction X and the second direction Y are parallel and spaced apart.

[0043] More specifically, the tapping portion 12 has a sheet-like structure, and its shape is not limited. The tapping portion 12 includes a first connecting portion 121 and a second connecting portion 122. The first connecting portion 121 and the second connecting portion 122 are integrally formed. The first connecting portion 121 and the second connecting portion 122 are used to pass through the connecting belt 30. In some embodiments, as Figure 6 shown, the first connecting portion 121 and the second connecting portion 122 are used to pass through the same connecting belt 30. In some embodiments, as Figure 7 shown, the first connecting portion 121 and the second connecting portion 122 are used to pass through different connecting belts 30. Of course, for the present utility model, as Figure 6 shown, the arrangement of the first connecting portion 121 and the second connecting portion 122 is mainly used to pass through the same connecting belt 30 so that the connecting belt 30 extends in different directions to play a tapping role. In some cases, the user can also pass the first connecting portion 121 and the second connecting portion 122 through different connecting belts 30 respectively according to needs to play a similar role.

[0044] For the convenience of passing through the connecting belt 30, a first through hole 1211 is provided on the first connecting portion 121, and a second through hole 1221 is provided on the second connecting portion 122. The first through hole 1211 and the second through hole 1221 are spaced apart. Among them, the first connecting portion 121 is configured such that when the connecting belt 30 passes out through the first through hole 1211, the connecting belt 30 extends outward along the first direction X. The second connecting portion 122 is configured such that when the connecting belt 30 passes out through the second through hole 1221, the connecting belt 30 extends outward along the second direction Y.

[0045] Preferably, the first connecting portion 121 and the second connecting portion 122 are used to movably pass through the same connecting belt 30, and are configured to allow the same connecting belt 30 to pass through the first through hole 1211 and the second through hole 1221 in sequence to change the setting direction of the connecting belt 30, so that the connection extends outward along the first direction X and the second direction Y relative to the male buckle 10.

[0046] One end of the first connecting portion 121 and the second connecting portion 122 is integrally formed, and the other end is spaced apart, thus forming a bifurcated structure.

[0047] In some embodiments, only the first through hole 1211 is provided on the first connecting portion 121, and only the second through hole 1221 is provided on the second connecting portion 122, and no other holes for passing through the connecting belt 30 are provided. At this time, as Figure 7As shown, the first connecting portion 121 and the second connecting portion 122 are preferably applicable to connecting different connecting bands 30. If they are used for threading the same connecting band 30, when the same connecting band 30 passes through the first through hole 1211 and the second through hole 1221 in sequence, for the flat connecting band 30, the connecting band 30 will not be able to extend smoothly due to the sudden change in direction. At this time, the surface of the connecting band 30 cannot fit well with the surface of the tapping portion 12. If the male buckle 10 is used for a helmet, the connecting band 30 will not fit well with the face and will be uncomfortable to wear.

[0048] To avoid the situation where the flat connecting band 30 cannot fit well with the surface of the tapping portion 12 when passing through the first through hole 1211 and the second through hole 1221, as Figure 4 、 Figure 6 shown, a third through hole 1212 and a fourth through hole 1222 are further provided on the tapping portion 12.

[0049] The third through hole 1212 and the fourth through hole 1222 are respectively spaced from the first through hole 1211 and the second through hole 1221. The tapping portion 12 is configured such that the same connecting band 30 passes through the first through hole 1211, the third through hole 1212, the fourth through hole 1222, and the second through hole 1221 in sequence to change the setting direction of the connecting band 30 so that the connecting band 30 extends outward relative to the male buckle 10 along the first direction X and the second direction Y.

[0050] The third through hole 1212 and the fourth through hole 1222 can force the connecting band 30 to turn so that the connecting band 30 is arranged to fit with the two side surfaces of the tapping portion 12 with the same surface. In this way, the connecting band 30 can be extended and turned relatively smoothly, avoiding uncomfortable wearing.

[0051] For example, the two side surfaces of the tapping portion 12 are respectively referred to as the front surface 12a and the back surface 12b. When the connecting belt 30 enters the first through hole 1211 with its first surface 30a facing outward, the portion of the connecting belt 30 located between the first through hole 1211 and the third through hole 1212 is in contact with the front surface 12a of the tapping portion 12 with its second surface 30b; subsequently, the connecting belt 30 turns at the third through hole 1212. After the connecting belt 30 passes through the third through hole 1212, the portion of the connecting belt 30 located between the third through hole 1212 and the fourth through hole 1222 is in contact with the back surface 12b of the tapping portion 12 with its second surface 30b; subsequently, the connecting belt 30 turns at the fourth through hole 1222. After the connecting belt 30 passes through the fourth through hole 1222, the portion of the connecting belt 30 located between the fourth through hole 1222 and the second through hole 1221 is in contact with the front surface 12a of the tapping portion 12 with its second surface 30b. At this time, the first surface 30a of the connecting belt 30 faces outward and has the same surface orientation as the connecting belt 30 when it enters the first through hole 1211. Subsequently, the connecting belt 30 passes through the second through hole, and the surface of the connecting belt 30 does not change.

[0052] Through the third through hole 1212 and the fourth through hole 1222, the surface of the flat connecting belt 30 can be arranged to fit along the surface of the tapping portion 12, so as to ensure the smooth extension of the flat connecting belt 30 to the greatest extent.

[0053] Furthermore, the third through hole 1212 is configured such that when the connecting belt 30 passes through the third through hole 1212, the connecting belt 30 points to the first through hole 1211 along the first direction X. In other words, when the connecting belt 30 is between the third through hole 1212 and the first through hole 1211, the connecting belt 30 extends along the first direction X in the direction of its length, so that the connecting belt 30 does not turn at the first through hole 1211, and further enables the connecting belt 30 to extend substantially along its own length and remain smooth.

[0054] Similarly, the fourth through hole 1222 is configured such that when the connecting belt 30 passes through the fourth through hole 1222, the connecting belt 30 points to the second through hole 1221 along the second direction Y. In other words, when the connecting belt 30 is between the fourth through hole 1222 and the second through hole 1221, the connecting belt 30 extends along the second direction Y in the direction of its own length, so that the connecting belt 30 does not turn at the second through hole 1221, and further enables the connecting belt 30 to extend substantially along its own length and remain smooth.

[0055] To be suitable for the use of the flat connecting belt 30, the first through hole 1211, the second through hole 1221, the third through hole 1212, and the fourth through hole 1222 are all strip-shaped holes. Preferably, the first through hole 1211, the second through hole 1221, the third through hole 1212, and the fourth through hole 1222 are arranged coplanarly or substantially coplanarly.

[0056] In order to ensure smooth extension of the flat connecting belt 30, the third perforation 1212 and the fourth perforation 1222 are inclined at a first angle in their length direction, the first perforation 1211 and the third perforation 1212 are inclined at a second angle in their length direction, and the second perforation 1221 and the fourth perforation 1222 are inclined at a third angle in their length direction.

[0057] The first angle, the second angle, and the third angle may be the same or different.

[0058] The first angle may be a right angle, an acute angle or an obtuse angle. In this embodiment, the first angle is preferably a right angle or close to a right angle.

[0059] The second angle and the third angle are preferably the same, and in this embodiment, they are set to be acute angles.

[0060] For comfortable use, the first connection portion 121 and the second connection portion 122 are symmetrically arranged; the first through hole 1211 and the second through hole 1221 are symmetrically arranged, and the third through hole 1212 and the fourth through hole 1222 are symmetrically arranged, and their symmetry centers coincide.

[0061] Furthermore, in order to enhance the friction between the connecting belt 30 and the branching portion 12, a plurality of protrusions are provided on the surface of the branching portion 12. The shape of the protrusions is not limited, and they can be circular protrusions or non-circular protrusions.

[0062] Furthermore, protrusions, such as sawtooth-shaped protrusions, may be provided on the inner walls of the third through hole 1212 and the fourth through hole 1222 to enhance friction.

[0063] like Figures 1 to 3 As shown, the male buckle 10 is provided with a matching locking portion 13 engaged with the female buckle 20. The matching locking portion 13 is protrudingly provided on the base portion 11. Preferably, the matching locking portion 13 is integrally formed on the base portion 11. A buckle hole 14 is provided on the base portion 11 or the junction portion 12.

[0064] The male buckle 10 further includes a protective member (not shown in the figure). The protective member is provided with an inserting portion, which can be engaged with the button hole 14. Through the engagement of the inserting portion with the button hole 14, the protective member can be at least partially connected to the base portion 11 along a side away from the matching lock portion 13. The protective member being at least partially connected to the base portion 11 means that the protective member can extend beyond the range of the base portion 11 or not.

[0065] Preferably, the protective member is detachably connected to the base portion 11. The plugging portion can be disengaged from the buckle hole 14 to separate the protective member from the base portion 11.

[0066] The protective member can be used for installation, protection, or setting brand logos. It is detachably arranged on the base portion 11, facilitating the replacement of different protective members to meet different usage requirements.

[0067] Preferably, the protective member is made of silicone material and has a certain elasticity.

[0068] In addition, the present utility model also provides a lock, as Figures 1 to 3 shown, which includes the aforementioned male buckle 10 and female buckle 20.

[0069] The male buckle 10 and the female buckle 20 can be connected along a connection direction Z different from the plane O where the connecting band 30 is arranged.

[0070] The male buckle 10 and the female buckle 20 are connected along the connection direction Z and separated along the direction opposite to the connection direction Z. The connecting band 30 is threaded through the plane O transverse to the connection direction Z.

[0071] The male buckle 10 is provided with a locking portion 13, and the female buckle 20 is provided with a locking portion. The locking portion can be engaged with and disengaged from the locking portion 13. The locking portion can be an elastic structure or a non-elastic structure. Preferably, the locking portion is an elastic structure, and it disengages from the locking portion 13 through elastic deformation.

[0072] The female buckle 20 is provided with an operating portion, and the operating portion can move relative to the female buckle 20. Preferably, the operating portion moves along a direction transverse to the connection direction Z. The operating portion can actuate the locking portion to disengage the locking portion from the locking portion 13.

[0073] Correspondingly, the female buckle 20 is also provided with an installation portion 21 for threading the connecting band 30. Usually, a perforation is provided on the installation portion 21. When the connecting band 30 is connected to the installation portion 21, the connecting band 30 overlaps and extends.

[0074] When the lock of the present utility model is applied to a helmet, the helmet is provided with a first connecting band 30 and a second connecting band 30.

[0075] One end of the first connecting band 30 is fixedly connected to the helmet, and the other end returns to the part where it is fixedly connected to the helmet after passing through the installation portion 21 of the female buckle 20, so that the first connecting band 30 is integrally in a strip shape, and the female buckle 20 is sleeved on the first connecting band 30.

[0076] One end of the second connecting band 30 is fixedly connected to the helmet, and the other end passes through the first perforation 1211, the third perforation 1212, the fourth perforation 1222, and the second perforation 1221 on the tapping part 12 and then returns to the helmet and is fixed at different positions, so that the second connecting band 30 is in a fork shape, and the male buckle 10 is movably sleeved on the second connecting band 30 and can be slidably adjusted.

[0077] Although the present utility model has been disclosed through the above embodiments, the scope of the present utility model is not limited thereto. Without departing from the concept of the present utility model, the above components can be replaced by similar or equivalent elements known to those skilled in the art.
