[0044] (1) By setting that the safety helmet shell is connected to the cap body through a connecting sphere, the cap body is worn on the head, and the safety helmet shell is connected to the user's shoulder through a shoulder strap. The camera body arranged on the safety helmet shell takes pictures of the overhaul site. When the user wears the intelligent safety helmet for on-site overhaul, the cap body rotates with the user's head. At this time, the connecting sphere arranged on the inner wall of the assembly cavity rotates in the limit groove under the limitation of the limit groove. Due to the sphere connection method, the wearer's head can rotate freely during on-site overhaul without affecting the wearer's overhaul operation. Since the safety helmet shell is connected to the user's shoulder through a shoulder strap, the user's shoulder is relatively stable, so that the camera body arranged on the safety helmet shell can be in a relatively stable state, which is convenient for taking pictures of the overhaul site.

[0045] (2) By setting that the connecting member is rotatably arranged with the assembly side plate, during use, the connecting member rotates around the central axis of the connecting sphere. When the safety helmet shell is worn through the shoulder strap, the user can still adjust the shooting angle of the camera body by adjusting the rotation of the connecting member relative to the assembly side plate, which is convenient for observing and photographing the overhaul sites at different positions. After adjusting the camera body to the ideal position, the rotation position of the connecting member relative to the assembly side plate is positioned by rotating the positioning component. At this time, the camera body continuously aligns with the overhaul part, thereby completing the positioning process of the camera body, which is convenient for observing the overhaul site through the camera body.

[0046] (3) By setting up the rotating connection component, during use, the adjustment fitting pipe is inserted into the second arc-shaped groove, and the adjustment connection plug is inserted into the connection groove. Through the sliding connection of the fitting pipe relative to the second arc-shaped groove, the rotating connection of the sliding plate relative to the fitting side plate is achieved. By setting the fitting pipe and the second arc-shaped groove to be separable, it is convenient for the user to choose whether to connect the shoulder strap and the safety helmet shell according to the actual use situation. When it is necessary to connect the shoulder strap and the safety helmet shell, the fitting pipe is inserted into the interior of the second arc-shaped groove and the adjustment connection plug is adjusted to slide into the connection groove through the adjustment component. At this time, under the restriction of the connection plug, the fitting pipe cannot be separated from the second arc-shaped groove, and the fitting pipe slides relative to the second arc-shaped groove, thereby completing the rotating connection of the sliding plate relative to the fitting side plate, which is convenient for use.

At this time, the connecting ball 3 arranged on the inner wall of the assembly cavity 12 rotates in the limit groove 211 under the limitation of the limit groove 211. Due to the way the ball is connected, the wearer's head can be rotated at will during on-site maintenance without affecting the wearer's maintenance operation. Since the helmet shell 1 is connected to the user's shoulder through the shoulder strap 41, the user's shoulder is relatively stable, so that the camera body 11 arranged on the helmet shell 1 can be in a relatively stable state, which is convenient for photographing the maintenance site.

[0059] As a preferred embodiment, it also includes a first screw rod 6, wherein a locking slot 212 is opened on the cap body 21; the first screw rod 6 is threadedly connected to the helmet shell 1 and inserted into the locking slot 212, and fits with the slot wall of the locking slot 212.

[0060] In specific implementation, when the shoulder strap 41 is not worn, in order to prevent the safety helmet shell 1 from rotating relative to the helmet body 21 randomly and affecting the wearer's use, the first lead screw 6 can be rotated. At this time, under the action of the threaded connection, the first lead screw 6 rotates towards the direction close to the helmet body 21 and is inserted into the inside of the locking slot 212. At this time, the first lead screw 6 is in contact with the wall of the locking slot 212, which can prevent the safety helmet shell 1 from rotating relative to the helmet body 21 randomly and is convenient for use.

[0061] As a preferred implementation manner, it further includes a chin strap 22 and a first buckle 23. Among them, the number of the chin straps 22 is two, both are arranged on the helmet body 21, and the end far from the helmet body 21 can extend to the lower jaw; the first buckle 23 is arranged at the end of one of the chin straps 22 for positioning the distance between the ends of the two chin straps 22.

[0062] In specific implementation, when the user wears the helmet body 21 on the head position, the two chin straps 22 can be pulled to the lower jaw and the distance between the ends of the two chin straps 22 is positioned through the first buckle 23, so as to complete the wearing process of the helmet body 21.

[0063] As a preferred implementation manner, it further includes a second buckle 42. Among them, the second buckle 42 is arranged at one end of the shoulder strap 41, and it is provided with a belt hole 421 for the other end of the shoulder strap 41 to pass through, for positioning the moving position of the shoulder strap 41 relative to the belt hole 421.

[0064] In specific implementation, the shoulder strap 41 is wound around the shoulder and passes through the belt hole 421. The end of the shoulder strap 41 is pulled to make the shoulder strap 41 close to the shoulder and the moving position of the shoulder strap 41 relative to the belt hole 421 is positioned through the second buckle 42, so as to complete the wearing process of the shoulder strap 41. By pulling to change the area surrounded by the shoulder strap 41, the shoulder strap 41 can adapt to people of different body types and is convenient for use.

[0065] As a preferred implementation manner, the connecting component 5 includes an assembly side plate 51, a connecting piece 52 and a rotation positioning component 53. Among them, the assembly side plate 51 is arranged on the outer side of the safety helmet shell 1; the connecting piece 52 is rotatably arranged on the assembly side plate 51 and is fixedly connected to the shoulder strap 41, and the connecting piece 52 rotates with the central axis of the connecting sphere 3 as the rotation axis; the rotation positioning component 53 is arranged between the assembly side plate 51 and the connecting piece 52 for positioning the rotation angle of the assembly side plate 51 relative to the connecting piece 52.

[0066] In a specific implementation, the connecting member 52 rotates about the central axis of the connecting sphere 3, so that when the safety helmet shell 1 is worn through the shoulder strap 41, the user can still adjust the shooting angle of the camera body 11 by adjusting the relative rotation of the connecting member 52 with respect to the assembly side plate 51, which facilitates observing and photographing the maintenance sites at different positions. After the camera body 11 is adjusted to an ideal position, the rotation position of the connecting member 52 relative to the assembly side plate 51 is positioned by rotating the positioning assembly 53. At this time, the camera body 11 continuously aligns with the maintenance part, thereby completing the positioning process of the camera body 11, which facilitates observing the maintenance site through the camera body 11.

[0067] As a preferred implementation manner, the connecting member 52 includes a sliding plate 521, a hinge member 522 and a connecting member 523.

[0068] With such a design, by arranging that the sliding plate 521 and the connecting member 523 are connected through the hinge member 522, when the sliding plate 521 is not connected to the assembly side plate 51, the position of the sliding plate 521 is adjustable, which facilitates the assembly connection process of adjusting the sliding plate 521 and the assembly side plate 51.

[0069] As a preferred implementation manner, the rotation positioning assembly 53 includes a first rack 531, a second lead screw 532 and a second rack 533. Among them, a first arc-shaped groove 511 is formed on one side surface of the assembly side plate 51 corresponding to the sliding plate 521, and a sliding groove 5211 is formed on the side of the sliding plate 521 close to the first arc-shaped groove 511; the first rack 531 is arranged inside the first arc-shaped groove 511; the second lead screw 532 is threadedly connected to the sliding plate 521, one end of which extends to the side of the sliding plate 521 away from the assembly side plate 51, and the other end extends into the sliding groove 5211; the second rack 533 is slidably arranged inside the sliding groove 5211 and is rotatably connected to the end of the second lead screw 532. When the second rack 533 slides towards the direction close to the first arc-shaped groove 511, the second rack 533 inserts into the first rack 531 and meshes with the first rack 531.

[0070] In a specific implementation, when it is necessary to position the rotational position of the sliding connection plate 521 relative to the assembly side plate 51, the second lead screw 532 is rotated. At this time, the second lead screw 532 rotates in a direction close to the first arc-shaped groove 511, and pushes the second rack 533 to move along the sliding connection groove 5211 in a direction close to the first rack 531. When the second rack 533 moves to the position of the first rack 531, the second rack 533 is inserted into and meshes with the first rack 531. During this period, the rotation of the sliding connection plate 521 can be prevented under the limitation of the first rack 531 and the second rack 533, thereby completing the positioning process of the rotational position of the sliding connection plate 521.

[0071] As a preferred implementation manner, it further includes a rotational connection assembly 7. The rotational connection assembly 7 includes an assembly pipe 71, a connection plug 72, and an adjustment member 73. Among them, a second arc-shaped groove 512 is formed on one side surface of the assembly side plate 51 corresponding to the sliding connection plate 521, and a connection groove 513 is formed in the second arc-shaped groove 512; the assembly pipe 71 is arranged on the sliding connection plate 521, and one end of it is inserted into the second arc-shaped groove 512 and fits with the second arc-shaped groove 512; the connection plug 72 is slidably arranged on the assembly pipe 71 and can slide to be inserted into or separated from the connection groove 513. When the connection plug 72 is inserted into the connection groove 513, the assembly pipe 71 can move along the second arc-shaped groove 512; the adjustment member 73 is used to adjust the sliding of the connection plug 72 in a direction close to or away from the connection groove 513.

[0072] With such a design, by adjusting the assembly pipe 71 to be inserted into the second arc-shaped groove 512 and the connection plug 72 to be inserted into the connection groove 513, and through the sliding connection of the assembly pipe 71 relative to the second arc-shaped groove 512, the rotational connection process of the sliding connection plate 521 relative to the assembly side plate 51 is realized. By setting the assembly pipe 71 and the second arc-shaped groove 512 to be separable, it is convenient for the user to choose whether to connect the shoulder strap 41 and the safety helmet shell 1 according to the actual usage situation. When it is necessary to connect the shoulder strap 41 and the safety helmet shell 1, the assembly pipe 71 is inserted into the inside of the second arc-shaped groove 512 and the connection plug 72 is adjusted by the adjustment member 73 to slide and be inserted into the connection groove 513. At this time, under the limitation of the connection plug 72, the assembly pipe 71 cannot be separated from the second arc-shaped groove 512, and the assembly pipe 71 slides relative to the second arc-shaped groove 512, thereby completing the rotational connection process of the sliding connection plate 521 relative to the assembly side plate 51, which is convenient for use.

[0073] As a preferred embodiment, the adjusting member 73 includes a third lead screw 731, a pushing member 732 and a spring 733. Among them, the third lead screw 731 is threadedly connected to the fitting pipe 71, and one end thereof moves in a direction close to or away from the connecting plug 72; the pushing member 732 is arranged at one end of the third lead screw 731 close to the connecting plug 72 and abuts against the connecting plug 72. One side surface of the connecting plug 72 that abuts against the pushing member 732 is an inclined surface. When the pushing member 732 moves in a direction close to the connecting plug 72, the connecting plug 72 slides in a direction close to the connecting groove 513; the spring 733 is arranged between the connecting plug 72 and the fitting pipe 71 and is used to reset the sliding position of the connecting plug 72 relative to the fitting pipe 71.

[0074] In specific implementation, when it is necessary to adjust the connection between the connecting plug 72 and the connecting groove 513, the third lead screw 731 is rotated. At this time, the third lead screw 731 pushes the pushing member 732 in a direction close to the connecting plug 72 under the action of the threaded connection. Since one side surface of the connecting plug 72 that abuts against the pushing member 732 is an inclined surface, when the pushing member 732 moves in a direction close to the connecting plug 72, the connecting plug 72 slides in a direction close to the connecting groove 513, so that the connecting plug 72 is inserted into the inside of the connecting groove 513, thereby completing the sliding connection process of the fitting pipe 71 relative to the second arc-shaped groove 512. By arranging the spring 733, when the third lead screw 731 is rotated back, the connecting plug 72 can slide out of the connecting groove 513 under the action of the spring 733, which facilitates the user to detach the fitting pipe 71 from the second arc-shaped groove 512 and is convenient to use.

[0075] As a preferred embodiment, it further includes a knob 8. Among them, the number of knobs 8 is at least two, which are respectively arranged at one end of the second lead screw 532 away from the second rack 533 and one end of the third lead screw 731 away from the pushing member 732.

[0076] With such a design, when it is necessary to adjust the rotation of the second lead screw 532 and the third lead screw 731, the rotation can be adjusted through the knob 8, which is convenient to use.

[0077] The working principle of the present invention is introduced as follows:

[0078] The cap body 21 is worn on the head, and the shoulder strap 41 is worn on the shoulder. The safety helmet shell 1 is connected to the shoulder strap 41 through the connecting component 5. The video camera body 11 provided on the safety helmet shell 1 is used to photograph the maintenance site. When the user wears this intelligent safety helmet for on-site maintenance, the cap body 21 rotates following the user's head. At this time, under the rotational connection of the connecting sphere 3, the relative position of the safety helmet shell 1 can be kept stable. Due to the sphere connection method, when the wearer is performing on-site maintenance, the head can rotate freely without affecting the wearer's maintenance operation. Since the safety helmet shell 1 is connected to the user's shoulder through the shoulder strap 41, the user's shoulder is relatively stable, so that the video camera body 11 provided on the safety helmet shell 1 can be in a relatively stable state, facilitating the photography of the maintenance site. When the shoulder strap 41 is not worn, in order to prevent the safety helmet shell 1 from rotating randomly relative to the cap body 21 and affecting the user's use, the first lead screw 6 can be rotated so that the first lead screw 6 is inserted into the locking slot 212 and fits against the slot wall of the locking slot 212, which can prevent the safety helmet shell 1 from rotating randomly relative to the cap body 21 and is convenient for use. By setting the connecting member 52 to be rotatably arranged with the assembly side plate 51, when the safety helmet shell 1 is worn through the shoulder strap 41, the user can still adjust the shooting angle of the video camera body 11 by adjusting the rotation of the connecting member 52 relative to the assembly side plate 51, facilitating the observation and photography of the maintenance sites at different positions. After adjusting the video camera body 11 to the ideal position, the rotational position of the connecting member 52 relative to the assembly side plate 51 is positioned by rotating the positioning component 53. At this time, the video camera body 11 continuously aligns with the maintenance part, thus completing the positioning process of the video camera body 11 and facilitating the observation of the maintenance site through the video camera body 11. By setting the rotational connection component 7, during use, by adjusting the fitting tube 71 to be inserted into the second arc-shaped groove 512 and the connecting plug 72 to be inserted into the connecting groove 513, through the sliding connection of the fitting tube 71 relative to the second arc-shaped groove 512, the rotational connection process of the sliding plate 521 relative to the assembly side plate 51 is realized, so that the connection method between the shoulder strap 41 and the safety helmet shell 1 is a separable setting, facilitating the user to wear or not wear the shoulder strap 41 according to the actual use situation and connect the shoulder strap 41 and the safety helmet shell 1, which is convenient for use.

[0079] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
