Examples

Referring to fig. 1, 2, 3, 4, 5 and 6, the present embodiment provides a safety helmet with lenses, which includes a helmet shell 10, a lining 20 and a fixing insertion plate 30, wherein the lining 20 is sleeved in the helmet shell 10, a lens groove 201 is arranged at the front end of the lining 20, and a clamping groove 2011 is arranged at the outlet end of the lens groove 201; the front surface of the fixed inserting plate 30 is provided with a plurality of inserting grooves 301, and the fixed inserting plate 30 is arranged in the inserting groove 2011; the fixing plug board 30 is used for connecting and fixing an inner helmet sleeve, and a fixing piece 202 for fixing the inner helmet sleeve is arranged at the back neck of the lining 20.

In this embodiment, the fixing insert plate 30 may be integrally formed with the inner liner 20, or may be fixed by gluing or fastening. In addition, the safety helmet with the lenses is designed to be a concealed structure for the lenses, and the lenses can also be sunglasses. In detail, the safety helmet with the lenses is designed to be a three-layer structure, that is, the helmet shell 10 with a hard outer layer is made of steel or high molecular polymer, for example, special steel, glass fiber reinforced plastic, leather, nylon and other materials, so as to resist external impact or striking and play a role in safety protection; the middle layer is a lining 20, so that the buffer effect can be achieved, and the impact force given to the head by impact or striking can be effectively reduced; the inner layer is a helmet inner sleeve, so that the protective effect is achieved, sweat can be absorbed, or the comfort of wearing the helmet is improved. The inner sleeve of the helmet is made of cotton cloth and is designed into a detachable structure, so that the helmet is convenient to detach, clean and keep the sanitation in the helmet. When the inner sleeve of the helmet is not used, the inner sleeve can be detached to meet the requirements of different people and different environments and the like, and the corresponding adaptability and the practicability are improved.

Specifically, the lens groove 201 at the front end of the lining 20 can accommodate the sunglasses, so that the sunglasses are hidden between the helmet shell 10 and the lining 20, and the purpose of hiding and accommodating the sunglasses is achieved. A slot 2011 capable of accommodating the fixed plug board 30 is further formed in the lens groove 201 to form a stepped avoiding structure, so as to prevent interference of a sunglass lens rotary switch. Meanwhile, one end of the inner helmet sleeve is fixed through the slot 301 in the fixing plug board 30, the other end of the inner helmet sleeve is connected through the fixing piece 202, the fixing piece 202 can be connected through a zipper structure and a buckle structure, or can be fixed through a hook and loop fastener, the purpose of stably installing the inner helmet sleeve is achieved, meanwhile, the inner helmet sleeve is simple and convenient to disassemble and install, and the use experience is improved.

In this embodiment, the slot 301 is disposed in a conducting manner along the direction of the socket, and an inner hole of the slot 301 is in a bell-mouth structure (not shown). The slot 301 is the structure that both ends switched on, and the design of horn mouth structure is convenient for insert the gear shaping, forms the quick grafting of helmet endotheca fixed, can reach firm fixed purpose simultaneously, improves the steadiness of structure.

Further, the equidistant three that is provided with of slot 301 in this embodiment, three slot 301's design can guarantee to spread out the cover with the helmet endotheca and establish in inside lining 20 to it is firm fixed, improve the practicality.

As shown in fig. 7, the helmet further includes a connecting plate 50, the connecting plate 50 is provided with elastic gear teeth 501 matching with the slots 301, the number of the elastic gear teeth 501 is the same as that of the slots 301, and the connecting plate 50 is disposed on the helmet inner shell. The connecting plate 50 is connected with the elastic gear teeth 501 on the connecting plate 50, so that rapid insertion can be realized, and the inner sleeve of the helmet can be conveniently fixed on the connecting plate 50, for example, the use convenience is improved in a sewing mode.

Further, as shown in fig. 6, in the present embodiment, the plate surface of the fixed board 30 is provided with an introduction groove 303 extending in a direction toward the entrance of the slot 301. Through the arrangement of the leading-in groove 303, after the elastic gear shaping 501 is inserted into the slot 301, the elastic gear shaping 501 cannot deviate or slide, so that the effect of limiting the elastic gear shaping 501 is achieved, and the stability of the installed inner sleeve of the helmet is improved.

As shown in fig. 6 and 7, the rear surface of the fixed insert plate 30 in this embodiment is provided with a plurality of connecting members 302, and the connecting members 302 are used to mount the fixed insert plate 30 in cooperation with the inner liner 20. The setting of connecting piece 302 need not to adopt the mode of glue or sticky tape to bond, utilizes the fixed picture peg 30 of cooperation installation of structure, and is higher in stability, and difficult the emergence is come off, and can dismantle, install and use, and the maintenance of being convenient for improves the practicality.

Further, as shown in fig. 6, the connecting member 302 in the present embodiment includes a stopper 3021 and a link 3022 connecting and stopping the stopper 3021 and the fixed board 30, and the cross-sectional area of the link 3022 is smaller than that of the stopper 3021. Form the cooperation structure of similar button, button and through-hole cooperation are connected in the clothes promptly, because inside lining 20 is buffer material, consequently have elasticity, consequently have good elasticity performance, be convenient for insert connecting piece 302, form through dog 3021 and block afterwards, prevent that fixed picture peg 30 from breaking away from inside lining 20, reach the purpose of firm fixed.

As shown in fig. 3, 4 and 5, in this embodiment, the inner liner 20 includes a main body portion 203 and a lens portion 204, a clearance accommodating cavity 40 is disposed between the lens portion 204 and the helmet shell 10, the main body portion 203 is provided with a contour groove 2031 for accommodating the lens portion 204, and a protrusion 2032 for fitting and fixing with the lens portion 204 is disposed at the bottom of the contour groove 2031. Because the lens groove 201 is needed to be disposed on the lens portion 204 to accommodate the lens, the inner liner 20 disposed in a split structure facilitates adjusting the space size of the clearance cavity 40 to coordinate lens structures with different thicknesses, and the adaptability is high. The contour of the groove body of the contour groove 2031 of the main body part 203 is the same as the contour of the contact lens part 204, so that the lens part 204 can be fitted in the contour groove 2031, and the lens part has good integral performance by fixing.

For the cooperation of main part 203 and lens part 204, can adopt the mode of bonding to connect, stack up the setting through outstanding arch 2032 and lens part 204 in profile groove 2031, and then increase the area that can the adhesion, improve the steadiness of structural connection.

Further, as shown in fig. 4, both sides of the contour groove 2031 in the present embodiment are provided with a convex 2032 or a concave arc surface 2033. The arcuate surface 2033 is designed such that when the lens portion 204 is placed in the contour groove 2031, the lens portion 204 cannot move toward the notch of the contour groove 2031, thereby forming a limit. The degree of freedom of the lens portion 204 is reduced, achieving the purpose of stable fixation.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
