Detailed Description

The following further describes embodiments of the present invention with reference to the accompanying drawings:

in the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art, that the present invention may be practiced without one or more of these specific details. In other instances, well-known features have not been described in order to avoid obscuring the invention.

Current intelligent security cap is equipped with communication positioner's communication box in the outside fixed connection of safety cap, and most communication boxes adopt the screw to fix the communication box on the cap, also need the screwdriver to dismantle usually when dismantling for the dismouting process need be with the help of specialized tool, and the screw hole is a plurality of makes the dismouting process loaded down with trivial details.

Secondly, the arc-shaped surface adopted on the surface of the safety helmet can disperse the stress of the stress area in the stress process of the safety helmet, and because the screw is vertically connected with the surface of the safety helmet, the stress of the mounting surface under the impact or extrusion of a hard object can drive the screw to reduce the stress area of the safety helmet and puncture the safety helmet, so that the stress-dispersing arc surface of the safety helmet is broken, and the safety helmet cannot achieve the protection effect, and in addition, the sharp end of the screw can also damage the head of a person in the safety helmet; the potential safety hazard is very large. Accordingly, the present embodiment provides the following safety helmet.

As shown in fig. 1, the present embodiment provides a helmet with a detachable communication box, which includes a helmet body 2 and a communication box inserted into the helmet body 2. For the embodiment, the helmet body 2 and the communication box are both the prior art, and the embodiment does not improve the prior art, and for the personnel in the embodiment, the shape and the structure of the helmet and the working principle of the communication box are known, and the embodiment is not described in detail.

As an improvement point of this embodiment, in this embodiment, corresponding grooves 1 are symmetrically formed on both sides of the helmet body 1;

as another improvement point of this embodiment, the back of the communication box is provided with a protrusion for matching with the groove 1.

Preferably, as shown in fig. 2, 2 strip-shaped bosses 10 are arranged in the groove 1 in this embodiment, and strip-shaped gaps 11 are formed between the 2 strip-shaped bosses 10.

Preferably, as shown in fig. 2, the two end portions of the groove 1 are further provided with corresponding limiting plates, and a corresponding strip-shaped gap 11 is formed between each limiting plate and the corresponding strip-shaped bump 10. And the width of the strip gap 11 formed between the limiting plate and the strip-shaped convex block 10 is smaller than the width of the strip gap 11 between the strip-shaped convex block 10 and the strip-shaped convex block 10. And a plurality of magnet blocks 12 are arranged in each strip-shaped notch.

Preferably, a socket is further arranged in the groove 1, as shown in fig. 4, the socket includes a mounting seat 30, a socket opening 31 and a spring member 32, the mounting seat 30 is arranged in the groove 1, the socket opening 31 is formed in the mounting seat 30, and the spring member 32 is sleeved in the socket opening 31. In this embodiment, in order to keep the light weight of the safety helmet, the socket of this embodiment is made of a plastic material.

Preferably, a lower plate 21 is inserted into the socket 31, as shown in fig. 3, the lower plate 21 is provided with a plurality of sockets 22 and pins 23, and the pins 23 are matched with the socket 31 of the socket. The spring member 32 of this embodiment can prevent the excessive pressing force above the pin 23 from damaging the socket 31, and thus can buffer the pressing force during the installation process.

Preferably, a fastening hole 33 is further formed in the socket 31, and a thread adapted to the head of the pin 23 is further formed on the inner side wall of the fastening hole 33 to add friction force to the fastening portion.

Preferably, as shown in fig. 3, the protrusion is a plurality of upper convex plates 20 disposed on the back of the communication box body, and a plurality of the upper convex plates 20 are matched with a plurality of inserting openings 22 on the lower convex plates 21.

Preferably, the upper convex plate 20 is provided with a metal block for matching with the magnet block 12, and during installation, the upper convex plate 20 passes through the strip-shaped notch 11 and then is inserted into the insertion opening 22.

In the using process, the lower convex plate 21 is fixed on the inserting port 31 of the groove 1 through the plug pins 23, then the communication box is inserted into the inserting port 22 above the lower convex plate 21 through the upper convex plate 20 on the back side to complete the integral fixation of the communication box, the communication box is pressed inwards to enable the metal surface on the back side to be attached to the magnetic suction block 12, and then the communication box is completely attached to the groove 1, so that the convex block is prevented from loosening and wearing the groove 1 in the groove 1; and the limiting plate integrally limits the bump.

The number of the pins 23 is increased by the bottom of the lower convex plate 21 to increase the stress area, so that the stability between the lower convex plate 21 and the groove 1 is maintained; therefore, the stability of the upper convex plate 20 connected to the lower convex plate 21 and the communication box is improved, and meanwhile, the adsorption force generated between the upper convex plate 20 and the magnetic suction block 12 is assisted to offset the problems that the vibration frequency of the socket is different and the center of gravity of the socket is changed frequently.

The foregoing embodiments and description have been presented only to illustrate the principles and preferred embodiments of the invention, and various changes and modifications may be made therein without departing from the spirit and scope of the invention as hereinafter claimed.
