[0026] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Any modification, equivalent replacement, improvement, etc. obtained by those skilled in the art without creative labor based on the embodiments of the present application should be included in the protection scope of the present application.

[0027] As shown in the drawings, Figures 1-2 The technical solution solved by the present application is that the self-resetting release device comprises a release device box (box body) 1, an upper pull buckle 2, a lower pull buckle 3, a release swing piece 7, a rotating shaft 9 and a release device limiting frame 13. The upper pull buckle 2 is connected through the rotating shaft 9, a self-resetting elastic member 10 and the release swing piece 7. The release device limiting frame is arranged in a release device lower hole 5.

[0028] The upper pull buckle 2 has an upper pull buckle pull hole 6 at one end, which is used for passing through a hat band 14. The other end of the hat band 14 is fixed on the rotating shaft 9 and can rotate along the rotating shaft 9 after being stressed.

[0029] The release swing piece 7 is fixed at one end on the rotating shaft 9 and can rotate along the rotating shaft 9 after being stressed. The other end has an end arc-shaped swing block 8, which can be released from a lower pull buckle upper hole 11 of the lower pull buckle 3 and the release device limiting frame 13 after being stressed and rotated.

[0030] The lower pull buckle 3 has the lower pull buckle upper hole 11 at one end and a lower pull buckle lower hole 11 for passing through a lower hat band 15 at the other end. The self-resetting elastic member 10 is fixed at one end on the rotating shaft 9 and the other end spring is linearly limited inside the upper pull buckle 2. The rotating shaft 9 is fixed at both ends on the release device box.

[0031] As Figure 3 shown, the safety helmet of the application is installed with the self-resetting tripping device, comprising a hat body 19 with an open lower end and a protective band 18 installed in the inner cavity of the hat body 19; the self-resetting tripping device 20 is installed at the lower end edge of the inner cavity of the hat body 19, one end of the upper hat band 14 is connected to the hollow part of the upper pull buckle, one end of the lower hat band 15 is connected to the lower pull buckle lower hole of the lower pull buckle, and the rear end of the upper hat band 14 passes through the top end of the protective band 18 and is connected to the rear end of the lower hat band 15 after being extended downward. The rear end of the upper hat band 14 is connected to the rear end of the lower hat band 15 to form a closed loop that can be easily worn by the user, and the rear end of the upper hat band 14 passes through the top end of the protective band 18, so that the protective band 18 limits the upper hat band 14 and the lower hat band 15 of the closed loop, and the upper hat band 14 cannot directly hang down.

[0032] The actual use of the utility model is:

[0033] After the hat band at both ends of the safety helmet self-resetting tripping device is stressed, the upper hat band 14 drives the upper pull buckle 2 to be pulled out of the tripping device upper hole 4, the upper pull buckle 2 drives the self-resetting elastic member 10 and the tripping swing piece 7 to rotate along the rotating shaft 9, the end arc swing block 8 at the end of the tripping swing piece 7 rotates and comes out of the lower pull buckle upper hole 11 and the tripping device limiting frame 13, at this time, the lower pull buckle 3 and the lower hat band 15 come out of the tripping device, and the safety helmet hat band is automatically separated after being stressed by a certain force.

[0034] After the lower pull buckle 3 and the lower hat band are separated, the stress on the hat band is removed, the self-resetting elastic member 10 drives the upper pull buckle 2 and the tripping swing piece 7 to rotate along the rotating shaft 9, the end arc swing block 8 on the tripping swing piece 7 rotates and returns to the tripping device limiting frame 13, and the self-resetting function of the safety helmet is realized after the stress is removed.

[0035] When the safety helmet is used again, the lower pull buckle upper hole 11 end of the lower pull buckle 3 is inserted into the tripping device lower hole, at this time, the upper end of the lower pull buckle 3 presses the end arc swing block 8, and then the upper end of the lower pull buckle 3 slides downward along the end arc swing block 8 under stress to the tripping device limiting frame 13, the tripping device limiting frame 13 limits the swing amplitude of the end arc swing block 8, so that the end arc swing block 8 can be separated from the lower pull buckle but not swing too much. In the process of sliding downward along the end arc swing block 8, the end arc swing block 8 rotates, the end arc swing block 8 temporarily comes out of the tripping device limiting frame 13 under stress, the lower pull buckle 3 smoothly passes through the end arc swing block 8 on the tripping swing piece 7, the end arc swing block 8 is inserted into the lower pull buckle upper hole 11 and the tripping device limiting frame 13 again, and the effect of using the safety helmet again is realized.

[0036] The utility model discloses simple structure is novel, and performance is reliable, provides a kind of self-resetting tripper for safety helmet, effectively solves safety helmet chinstrap to realize automatic disengagement after being subjected to certain force, greatly protects the life safety of worker. The internal structure of the tripper chinstrap is subjected to force and disconnects and has self-resetting function, and the disconnected chinstrap can be inserted into the lower hole of tripper again, reuse, green environmental protection, it is a technical innovation on safety helmet.
