[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described in the description of the utility model in combination with the drawings in the embodiments of the utility model, and it should be understood in the description of the utility model that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements indicated must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the utility model. Obviously, the described embodiments are only some of the embodiments of the utility model, not all of the embodiments.
[0023] A kind of anti-tripping device, as shown in Figures 1 to 2 It includes female buckle 1 and male buckle 2 made of nylon material, and the male buckle 2 has elastic sheets on both sides, and the female buckle 1 has accommodation holes on both sides to accommodate the elastic sheets, and the female buckle 1 is rotatably connected with an operating member 4 that communicates inside and outside the female buckle 1, and in order to simplify the structure of the female buckle 1, an installation hole 11 is formed on the surface of the female buckle 1 to communicate with the inside of the female buckle 1, and the operating member 4 is accommodated in the installation hole 11, and in order to facilitate the operation of the operating member 4, a plurality of engagement blocks 42 are fixedly arranged on the circumferential side of the operating member 4, and the female buckle 1 has an engagement groove 111 formed on the inner wall of the installation hole 11, and the engagement blocks 42 slide along the engagement groove 111, and the cross section of the engagement blocks 42 is triangular, and the operating member 4 can be installed on the female buckle 1 by clamping during production.
[0024] As shown in Figure 2 , Figure 3 , Figure 4 and Figure 5 , the side of the operating member 4 facing the inside of the female buckle 1 is provided with a plurality of intersecting second guide rails 41, and the inner wall of the female buckle 1 is provided with a first guide rail 12, one end of the first guide rail 12 extends to the inside of the operating member 4, and the other end of the first guide rail 12 is inserted into the female buckle 1 towards the position of the male buckle 2, and the male buckle 2 is provided with a sliding groove 21 having a U-shaped cross section and an opening facing the direction of insertion of the male buckle 2 into the female buckle 1, and the sliding groove 21 movably has a anti-tripping piece 3 that can enter the second guide rail 41 along the first guide rail 12, and in order to facilitate the user to distinguish the second guide rail 41 where the operating member 4 is located, the operating member 4 is made of a light-transmitting material.
[0025] In the initial state, the two buckles are separated, and at this time the first guide rail 12 communicates with any one of the second guide rails 41;
[0026] When the male buckle 2 is buckled with the female buckle 1, the elastic sheet of the male buckle 2 is extended from the accommodation hole through elastic deformation, and in this process, the anti-escape piece 3 moves along the first guide rail 12 until it enters the second guide rail 41, at this time, the anti-escape piece 3 is at the position where the second guide rails 41 intersect, after the anti-escape piece 3 enters the second guide rail 41, the anti-escape piece 3 can slide into other second guide rails 41 that are not aligned with the first guide rail 12 due to the change of its gravity, at the same time, the anti-escape piece 3 slides in the first direction along one end of the sliding groove 21, when trying to separate the male buckle 2 from the female buckle 1 by directly pressing the two elastic sheets, the operating piece 4 will rotate due to the guiding action of the anti-escape piece 3, and the anti-escape piece 3 will continue to slide in the second direction along both ends of the sliding groove 21 due to the relative sliding of the male buckle 2 and the female buckle 1, until it cannot slide, at this time, the operating piece 4 also cannot continue to slide, so that the male buckle 2 and the female buckle 1 cannot continue to be separated.
[0027] When it is necessary to unfasten the buckle, the operating piece 4 needs to be rotated first, so that the second guide rail 41 where the anti-escape piece is located is aligned with the first guide rail 12, and then the two elastic sheets are pressed, so that the male buckle 2 can be smoothly separated from the female buckle 1.
[0028] Beneficial effects: compared with the prior art, by increasing the limitation of the placement direction of the buckle when disassembling the buckle, the safety of the buckle is effectively improved.
[0029] As shown in Figure 1 and Figure 2 , in order to facilitate the use of the operating piece 4 by the user, two installation holes 11 are provided, that is, the operating piece 4 also has two, and at the same time, the outer surface of the operating piece 4 is formed with anti-skid lines, and in order to enable the other operating piece 4 to also receive the same rotating action through the transmission of the anti-escape piece 3 when one operating piece 4 is operated, the two ends of the anti-escape piece 3 are provided with sliding blocks for accommodating the anti-escape piece 3 in the first guide rail 12 or the second guide rail 41, and in order to reduce wear, the distance between the two sliding blocks away from the end surface is less than the distance between the inner walls of the female buckle 1 in the same direction.
[0030] As shown in Figure 3 , Figure 4 and Figure 5 , since the first direction length of the sliding groove 21 accommodating the sliding of the anti-escape piece 3 is relatively long, in order to facilitate the buckling of the female buckle 1 and the male buckle 2, the end of the first guide rail 12 away from the operating piece 4 is in a necked structure towards the operating piece 4, in order to make the movement of the anti-escape piece 3 more coherent, the maximum width of the first guide rail 12 at this position is greater than or equal to the width of the sliding groove 21, the cross section of the anti-escape piece 3 is in a circular shape, the minimum width of the first guide rail 12 is equal to the diameter of the cross section of the anti-escape piece 3, and the intersection position of the operating piece 4 in the second guide rail 41 is formed with a rounded corner structure.
[0031] It is apparent for a person skilled in the art that the present application is not limited to the details of the above-described exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary and non-limiting, the scope of the present application being defined by the claims appended hereto rather than by the above description, and all the changes which fall within the meaning and the scope of the equivalent elements of the claims are intended to be embraced therein.
