Description

Technical Field

[0001] The utility model relates to a safety device, and in particular to a buckle used for a safety sling. Background Art

[0002] The known full-body safety harness on the market is used to prevent the user from falling from a height when engaging in rock climbing or high-altitude operations, thereby ensuring that the user can maintain body stability when moving at high altitudes.

[0003] A general full-body safety harness comprises two shoulder straps, two abdominal straps and a buckle. The buckle connects the two abdominal straps and is fixed to the chest of the user. There is usually a D-ring between each shoulder strap and each abdominal strap as a chest hanging point of the safety harness, and the D-ring is used to connect an ascender, a descender or a lanyard.

[0004] At present, each shoulder strap and each abdominal adjustment belt are usually connected to the D-ring by sewing. However, fixing the D-ring to the safety harness by sewing not only increases the steps of manufacturing the safety harness, but also reduces the ability of the multiple shoulder straps and the multiple abdominal adjustment belts to support the user's body. In addition, when the user falls, the D-ring fixed by sewing will cause the shock force generated by the braking to be directly transmitted to the chest cavity and spine, and the chest muscles and back muscles will be directly compressed, making it impossible for the faller to perform self-rescue. Therefore, how to provide a buckle that combines a D-ring and improves wearing safety and comfort is a problem that needs to be solved urgently. Utility Model Content

[0005] In view of this, an object of the present invention is to provide a buckle for connecting a safety harness, which can improve the safety and comfort when wearing the safety harness.

[0006] In order to achieve the above-mentioned purpose, the utility model provides a buckle, comprising a first buckle body, a second buckle body, a connecting portion and a receiving portion, the first buckle body having a first body and a ring body, the ring body being pivotally connected to the first body and being able to rotate around a rod body; the second buckle body being detachably connected to the first buckle body, and the second buckle body having a second body; the connecting portion extending along an insertion axis direction; the receiving portion accommodating the connecting portion; wherein the receiving portion is arranged on the first body or the second body, the connecting portion is arranged on the second body or the first body arranged relative to the receiving portion, and the angle between the rod body of the first buckle body and the insertion axis direction is less than 90 degrees.

[0007] The effect of the utility model lies in that, through the design that the ring body is pivotally connected to the first body, when the ring body is used as a hanging point of the safety harness, the ring body can adapt to external forces at different angles and rotate around the rod body as the center, so as to ensure that the user can keep the body stable when moving at high altitudes, thereby improving the safety and comfort of the user wearing the safety harness.

[0060] The buckle of the utility model is used to connect the safety harness. In order to more clearly illustrate the utility model, the preferred embodiment is given and described in detail with the accompanying drawings as follows. Figures 1 to 3 As shown, the buckle 100 of the first preferred embodiment of the utility model comprises a first buckle body 10 and a second buckle body 20 which are detachably connected, the first buckle body 10 having a first body 12 and a ring body 14, the first body 12 having a first side edge 12a and a connecting side edge 12b adjacent to each other, the ring body 14 being pivotally connected to the first body 12 and close to the first side edge 12a of the first body 12, a first stringing portion 18 being disposed on the first body 12 and close to a side edge opposite to the connecting side edge 12b for connecting a webbing (not shown), a connecting portion 40 being disposed on the connecting side edge 12 of the first body 12 2b, the connecting portion 40 extends from the connecting side edge 12b along an insertion axis direction D; the second buckle body 20 has a second main body 22, the second main body 22 has a receiving side edge 22a, a receiving portion 30 is arranged on the receiving side edge 22a of the second main body 22 and is provided for accommodating the connecting portion 40, a second rope threading portion 24 is arranged on the second main body 22 and is close to a side edge relative to the receiving side edge 22a for connecting another webbing (not shown); when the connecting portion 40 is accommodated in the receiving portion 30, the connecting side edge 12b of the first main body 12 abuts against the receiving side edge 22a of the second main body 22.

[0061] In this embodiment, the connecting portion 40 is disposed on the first body 12 , and the receiving portion 30 is disposed on the second body 22 . In other embodiments, the connecting portion 40 may also be disposed on the second body 22 , and the receiving portion 30 may be disposed on the first body 12 .

[0062] Please refer to Figure 2 and Figure 3 As shown, the first body 12 has an axial hole 12d passing through it along the insertion axis direction D, and the axial hole 12d is close to the first side edge 12a of the first body 12. The first buckle body 10 has a rod body 16, and the rod body 16 has a body 16b and two heads 16a connected to the two ends of the body 16b, wherein the outer diameter of each head 16a is greater than the outer diameter of the body 16b, and the body 16b passes through the axial hole 12d of the first body 12 and the two through holes 14a at the two free ends of the ring body 14, and a side of each head 16a close to the body 16b abuts against the outer side surface of each free end of the ring body 14; therefore, as shown Figure 5 As shown, the ring body 14 can rotate along a ring body rotation direction R with the rod body 16 as the center, so that when the ring body 14 is used as a hanging point and connected to an ascender, a descender or a lanyard, the ring body 14 can rotate in accordance with external forces at different angles to ensure that the user maintains body stability when moving at high altitude.

[0063] like Figure 2 As shown, the angle between the rod body 16 of the first buckle body 10 and the insertion axis direction D is equal to 0 degrees, that is, the rod body 16 is parallel to the insertion axis direction D. Therefore, when the ring body 14 is pivotally connected to the first body 12 through the rod body 16 and the ring body 14 is used as a hanging point of the safety harness, the safety of the user can be ensured.

[0064] In this embodiment, the ring body 14 is C-shaped. In other embodiments, the ring body 14 may also be arc-shaped or polygonal.

[0065] In this embodiment, the angle between the rod body 16 of the first buckle body 10 and the insertion axis direction D is equal to 0 degrees. In other embodiments, the angle between the rod body 16 and the insertion axis direction D may also be less than 90 degrees. In addition, in other embodiments, the angle between the rod body 16 and the insertion axis direction D may also be less than or equal to 30 degrees. Therefore, when the ring body 14 is pivotally connected to the first body 12 through the rod body 16, and the ring body 14 is used as a hanging point, it can avoid the upward pulling force applied to the ring body 14 from being too unevenly distributed, thereby ensuring that the user maintains body stability when moving at high altitudes.

[0066] Please refer to Figure 2 As shown, the connecting portion 40 has a first snake piece 42 and a second snake piece 44 which are partially overlapped and connected, the second snake piece 44 is in a sheet shape, and one end of the second snake piece 44 is connected to the connecting side edge 12b of the first body 12 and extends along the insertion axis direction D, one side of the second snake piece 44 is connected to a first top surface 12c of the first body 12, and the second snake piece 44 is connected to the first snake piece 42 in an overlapping manner relative to the side connected to the first top surface 12c, the first snake piece 42 is in a sheet shape, one end of the first snake piece 42 is connected to the connecting side edge 12b of the first body 12 and extends along the insertion axis direction D, the first snake piece 42 has a connecting member 422 and a contact member 424 in sequence in the direction away from the first body 12 and along the insertion axis direction D, the connecting member 422 of the first snake piece 42 is overlapped and connected to one side of the second snake piece 44, and the contact member 424 of the first snake piece 42 protrudes from the second snake piece 44.

[0067] That is to say, the first snake piece 42 of the connecting part 40 has a first snake piece length L1 along the insertion axis direction D, and the second snake piece 44 of the connecting part 40 has a second snake piece length L2 along the insertion axis direction D, wherein the first snake piece length L1 is greater than the second snake piece length L2; in addition, the abutment member 424 of the first snake piece 42 has a width perpendicular to the insertion axis direction D, and the connecting member 422 of the first snake piece 42 has a width perpendicular to the insertion axis direction D, wherein the width of the abutment member 424 is greater than the width of the connecting member 422.

[0068] Please refer to Figures 2 to 4 As shown, the receiving portion 30 has a first accommodating groove 32 and a second accommodating groove 34, the second accommodating groove 34 is arranged at the receiving side edge 22a of the second body 22 and passes through a second top surface 22b of the second body 22, the side wall of the second accommodating groove 34 is connected to the second top surface 22b, the second accommodating groove 34 forms a second space S2 for accommodating the second snake piece 44 of the connecting portion 40, and the outer contour of the second snake piece 44 is consistent with the contour of the second accommodating groove 34; the first accommodating groove 32 is arranged between the second top surface 22b and a second bottom surface 22c of the second body 22, the first accommodating groove 32 forms a first space S1 for accommodating the first snake piece 42 of the connecting portion 40, and the first space S1 of the first accommodating groove 32 is connected to the second space S2 of the second accommodating groove 34.
