[0020] The following is a further detailed description of the specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0021] like Figures 1 to 4 As shown in FIG. 1 , it is a schematic diagram of the structure of the novel buckle that is easy to press provided by the utility model. The novel buckle that is easy to press includes a male buckle 10 and a female buckle 20 for inserting the male buckle 10. It can be imagined that the novel buckle that is easy to press also includes other functional modules such as a label set on the buckle surface, a strap connected to the buckle, etc., which are well known to those skilled in the art and will not be described in detail here.

[0022] The male buckle 10 is made of plastic injection molding and is integrally formed. It includes a pair of elastic pins 11, a guide tongue 12 located between the elastic pins 11, a strap connecting buckle 13 arranged on one side of the male buckle 10 in the pulling direction, and two limit blocks 14 respectively arranged on each of the elastic pins 11.

[0023] The two elastic pins 11 are symmetrical with the guide tongue 12 as the axis of symmetry, and each includes a guide end 111, a pressing portion 112 connecting the guide end 111 and the main body of the male buckle 10, and an elastic portion 113 connecting the guide end 111 and the guide tongue 12. The guide end 111 is the free end of the elastic pin 11 away from the main body of the male buckle 10, and extends in a direction away from the strap connection buckle 13, and an arc-shaped chamfer is provided at the end to guide the elastic pin 11 when it is inserted into the female buckle 20, so as to facilitate insertion. The pressing portion 112 is provided on the side of the elastic pin 11 away from the guide tongue 12, and is provided with an arc toward the guide tongue 12 to fit the arc of the fingertips, so that it can be pressed even when wearing gloves. In addition, the thickness of the pressing portion 112 is greater than the thickness of the guide end 111, so as to provide a larger contact surface when pressing, making pressing more convenient. The elastic portion 113 is disposed on one side of the elastic pin 11 close to the guide tongue 12 to provide elasticity together with the pressing portion 112 with higher elastic strength. After the buckle is buckled, the elastic pin 11 will not be easily deformed due to the force generated by the tension.

[0024] The guide tongue 12 is a guide structure arranged on the symmetry axis of the two elastic pins 11, and its extension direction is consistent with the extension direction of the elastic pins 11. The edges of the guide tongue 12 are all provided with arc chamfers to guide the elastic pins 11 when they are inserted into the female buckle 20, so as to facilitate insertion.

[0025] The shoulder strap connecting buckle 13 is of the style of a common backpack strap length adjustment buckle, which is used to adjust the shoulder strap length. It is a prior art and should be well known to those skilled in the art, so its structure and function will not be described in detail here.

[0026] The limit block 14 is arranged at the end of the free end of each of the elastic pins 11, and is arranged on the upper and lower surfaces perpendicular to the extension direction of the free end of the elastic pin 11, and is located on the side close to the guide tongue 12, and the limit block 14 is arranged at a right angle toward the extraction direction of the elastic pin 11 and away from the guide tongue 12, so as to resist against the corresponding structure of the female buckle 20, so that the male buckle 10 cannot be pulled out at will after being inserted into the female buckle 20, and its specific resisting structure will be described in detail below in conjunction with the specific structure of the female buckle 20.

[0027] The female buckle 20 is an insertion cavity made of plastic injection molding, which includes an insertion port 21, a guide groove 22 arranged in the insertion port 21, two pressing ports 23 arranged on both sides of the guide groove 22, four guide strips 24 respectively arranged at the pressing ports 23, and a strap mounting port 25 arranged at one end of the female buckle 20 away from the insertion port 21.

[0028] The width of the insertion opening 21 is such that the two elastic pins 11 can be accommodated. The guide groove 22 is located in the center of the insertion opening 21 and has a size that can just accommodate the insertion of the guide tongue 12, so that the male buckle 10 will not shake after being inserted into the female buckle 20. The two ends of the guide groove 22 in the insertion direction are connected, so that when the buckle is used in a snowy environment, it is convenient to discharge the snow in the buckle when it is buckled.

[0029] The pressing opening 23 is located on both sides of the female buckle 20 perpendicular to the opening direction of the insertion opening 21, and is generally in an inwardly concave arc structure, so that when the elastic pin 11 is inserted into the female buckle 20, both sides are exposed from the pressing opening 23. The pressing opening 23 is connected to the insertion opening 22, so that the pressing portion 112 passes through when the buckle is buckled.

[0030] The guide strip 24 is arranged on the inner wall of the female buckle 20 along the arc of the pressing port 23. It can be imagined that when the male buckle 10 is inserted into the female buckle 20, the limit block 14 and the guide strip 24 abut against each other, and drive the elastic pin 11 to deform inward along the arc structure of the guide strip 24. When the male buckle 10 is fully inserted into the female buckle 20, it is at the end of the guide strip 24 and cannot abut against the limit block 14. The elastic pin 11 rebounds. At this time, the limit block 14 and the guide strip 24 are misaligned, and the elastic pin 11 must be pressed inward to pull out the male buckle 10. At the same time, the end edge of the guide strip 24 away from the insertion port 21 is at a right angle, which is convenient for abutting against the limit block 14, thereby enhancing the structural strength, so that the elastic pin 11 is not easily deformed inward when subjected to a vertical pulling force in the insertion direction of the buckle, thereby unlocking the buckle to enhance the buckling strength of the buckle, and when the buckle is used on safety protection equipment such as a helmet, it can withstand higher pulling force.

[0031] The shoulder strap mounting opening 25 is a hollow hole arranged at the other end of the female buckle 20 away from the insertion opening 21, so as to connect and fix the backpack strap.

[0032] The main bodies of the male buckle 10 and the female buckle 20 can be arc-shaped, and present an arc shape after being buckled, so as to play an anti-mistake effect, and at the same time, it can also play a role in fitting the lower jaw when used as a component of a helmet.

[0033] Compared with the prior art, the new buckle provided by the utility model is convenient to press, by providing the pressing portion 112, the contact surface of the buckle is increased, so that the user can easily press the buckle to unlock even if wearing gloves. And by providing the pressing port 23 to communicate with the insertion port 21, the pressing portion 112 is fully exposed for pressing, which greatly facilitates the user to press and unlock the buckle. And by providing the guide strip 24 and the limit block 14 to be mutually offset, the buckle is locked, and the straight-pull locking ensures that the buckle can withstand higher tension, which is suitable for protective equipment such as helmets.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modification, equivalent substitution or improvement within the spirit of the present invention are included in the scope of the claims of the present invention.
