Referring to fig. 1 and 2, a miner's safety helmet for mining comprises a helmet shell 1, a helmet liner 2 fixedly connected to the inner side wall of the helmet shell 1, and an elastic head sleeve 3 arranged at the lower end of the helmet liner 2, wherein the elastic head sleeve 3 comprises an elastic band 20 and a head sleeve round tube 21 fixedly connected to the elastic band 20 at one end, and the other end of the elastic band 20 is slidably connected to the other end of the head sleeve round tube 21. The hat lining 2 comprises four hat supports 19, the upper ends of the hat supports 19 are fixedly connected with the top end of the hat shell 1 respectively, the head sleeve round tubes 21 are fixedly connected to the lower ends of the two adjacent hat supports 19, the lower ends of the other two adjacent hat supports 19 are fixedly connected with sleeve buckles, and the elastic bands 20 are connected in the sleeve buckles in a sliding mode. The headgear round tube 21 is provided with a locking mechanism which can automatically lock the safety helmet on the head of a wearer. Locking mechanism includes adjusting pole 13, response head rope 4, first spring 10 and compresses tightly subassembly 11 (see fig. 3), first spring 10 sets up in headgear pipe 21 and its both ends connect respectively the slip end of headgear pipe 21 and elastic cord 20, be equipped with the logical groove 8 of intercommunication headgear pipe 21 and cap shell 1 on the safety helmet, adjust pole 13 and pass logical groove 8 and elastic cord 20 slip end fixed connection, logical groove 8 is equipped with constant head tank 9 near 3 slip end departments of elasticity headgear, and constant head tank 9 intercommunication cap shell 1 and headgear pipe 21. The compressing component 11 is arranged in the positioning groove 9 and can press and fix the adjusting rod 13 in the positioning groove 9. Two of them cap of the cap body prop 19 and have seted up first through-hole 5 and second through-hole 6 correspondingly, and the inductive head rope 4 one end links to each other with compressing tightly subassembly 11, and the other end passes first through-hole 5 and fixed connection is on second through-hole 6. When wearing the safety helmet, the head of the wearer can support the induction head rope 4, the induction head rope 4 can drive the pressing component 11 to move away from the direction of the adjusting rod 13 after receiving the supporting force, the adjusting rod 13 enters the through groove 8 after losing the supporting force of the pressing component 11, the first spring 10 contracts, and the safety helmet is locked on the head of the wearer.

Referring to fig. 3 and 4, the pressing assembly 11 includes a connecting rod 16 and a lifting rod 15, the connecting rod 16 is hollow and tubular, one end of the connecting rod is far away from the bottom end of the cap with the positioning groove 9, the lifting rod 15 is slidably connected in the connecting rod 16, a second spring 17 is fixedly connected between the lifting rod 15 and the connecting rod 16, a connecting hole 18 is formed at the joint of the second spring 17 and the positioning groove 9, and one end of the sensing head rope 4 penetrates through the connecting hole 18 and the second spring 17 and is fixedly connected with the lifting rod 15. The lifting rod 15 can compress the adjusting rod 13 moving to the positioning groove 9 to prevent the adjusting rod 13 from moving to the through groove 8 and being locked by wrong tension when the adjusting rod is vibrated. Meanwhile, when the second spring 17 is compressed under the action of the induction head rope 4, the adjusting rod 13 is easy to move upwards into the through groove 8 when not pressed and has an automatic locking effect.

Furthermore, the lifting rod 15 is provided with a spherical magnet pressing ball 14 at the end far away from the connecting hole 18, the spherical design reduces the resistance of the adjusting rod entering the positioning groove 9, meanwhile, the magnet pressing ball 14 has certain magnetism, and when the pressing assembly 11 contracts, the magnet pressing ball 14 can attract the adjusting rod 13 to enter the through groove 8 to complete automatic locking.

A connecting ball 22 with the same diameter as the head sleeve round tube 21 is arranged at the joint of the adjusting rod 13 and the first spring 10, and the connecting ball 22 is respectively fixedly connected with the first spring 10 and the self-sliding end of the elastic band. The connecting ball 22 is provided with a through threaded hole, the circle center of the threaded hole penetrates through the ball center of the connecting ball 22, and one end of the adjusting rod 13 is provided with an external thread matched with the threaded hole so as to be fixed with the connecting ball 22 through threads. After the automatic locking is carried out, when the tightness of the elasticity headgear 3 needs to be adjusted by the wearer, the tightness of the elasticity headgear 3 can be changed by manually adjusting the expansion degree of the first spring 10 by unscrewing the adjusting rod 13, and the expansion degree of the first spring 10 can be fixed by screwing the adjusting rod 13 to the circular hollow part through the threaded hole on the connecting ball 22 after the tightness is finished.

The adjusting rod 13 is provided with a hand-held part 12 at the end far away from the connecting ball 22. The adjusting rod 13 can be conveniently tightened by a wearer through the hand-held part 12, so that the convenience of adjusting the tightness of the safety helmet is improved.

Referring to fig. 1, will lead to groove 8 one end and constant head tank 9 and set up the right hand side and be close to brim of a hat 7 department when the safety helmet is worn, can adjust regulation pole 13 to constant head tank 9 back when the safety helmet needs to be taken off, take off the safety helmet through brim of a hat 7 in the same trend, easy operation has improved the convenience of taking off the safety helmet.

The implementation principle of the embodiment is as follows: when the wearer is wearing the safety helmet, the induction head rope 4 is stretched when receiving the effort of the wearer's head to drive the contraction of the second spring 17, the magnet that leads to compressing tightly the subassembly 11 compresses tightly ball 14 and removes towards keeping away from adjusting pole 13 direction, adjusts pole 13 simultaneously and gets into logical groove 8, and first spring 10 contracts at once and drives elastic cord 20 slip until elasticity headgear 3 locks the wearer's head in headgear pipe 21.

When the wearer needs to adjust the tightness of the device, the adjusting rod 13 can be unscrewed by rotating the holding part 12, the position of the holding part 12 is moved along the length direction of the through groove 8 so as to change the stretching state of the first spring 10 and further adjust the tightness of the tightening headgear 3, and after the adjustment is finished, the adjusting rod is screwed down so as to fix the stretching state of the first spring 10.

When the wearer will take off the safety helmet, firstly unscrew the adjusting rod 13 through the hand-held part 12, and pull to the positioning groove 9 along the direction of the through groove 8, the pressing component 11 on the positioning groove 9 presses the adjusting rod 13 in the positioning groove 9, at the moment, the first spring 10 is in the maximum stretching state, meanwhile, the elastic head cover 3 is in the maximum loosening rotary table, at the moment, the wearer can smoothly take off the safety helmet, and the induction head rope 4 is restored to the original state after taking off the safety helmet.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
