DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0023] This embodiment provides a helmet goggles fixing strap, which is applied to a safety helmet 1, and the safety helmet 1 is equipped with a goggles binding strap 2, and its structural schematic diagram is shown as follows: Figure 1-Figure 6 As shown, the helmet windshield goggles fixing belt includes a glasses positioning belt 3, one end of which is fixed to the rear end of the safety helmet 1; a shell 4, which is fixedly embedded in the rear end of the safety helmet 1; the glasses positioning belt 3 penetrates the shell 4 from bottom to top, and a connecting structure is provided between the top of the glasses positioning belt 3 and the shell 4. With this structural mode, when the windshield goggles are idle, the windshield goggles binding belt 2 is pushed to move above the shell 4, and then the top of the glasses positioning belt 3 is pulled to connect with the shell 4 using the connecting structure, so that the windshield goggles binding belt 2 can be positioned at the top of the rear end of the safety helmet 1, so as to prevent the windshield goggles from slipping due to the loosening of the windshield goggles binding belt 2 during riding with the safety helmet 1.

[0024] Furthermore, in the present embodiment, a groove 10 capable of accommodating the glasses positioning belt 3 to pass through is provided on the back of the shell 4, and is used for restraining and limiting the glasses positioning belt 3. A support block 18 is provided on the top of the shell 4, and a ridge 19 is provided on the side of the support block 18 away from the safety helmet 1. The setting of the support block 18 and the ridge 19 can limit and restrain the windproof glasses binding belt 2, thereby enhancing the limiting effect of the windproof glasses binding belt 2. Furthermore, a connecting end piece 5 is provided on the top of the glasses positioning belt 3, which is used for connecting the glasses positioning belt 3 with the shell 4 by a connecting structure, and the glasses positioning belt 3 is provided with an identification placement position.

[0025] As a preferred technical solution in this embodiment, the connecting structure is a letter lock buckle 6, the sub-mouth and the mother buckle of the letter lock buckle 6 are respectively fixed on the top of the glasses positioning belt 3 and the shell cover 4. Through the buckle of the letter lock buckle 6, the glasses positioning belt 3 and the shell cover 4 can be quickly connected, which is used for the binding and limiting of the windproof glasses binding belt 2, and is easy to disassemble. Example 2

[0026] The connecting structure is a limiting ring belt 7, both ends of which are fixed on the shell 4, and the glasses positioning belt 3 can pass through the limiting ring belt 7 and the shell 4. The top of the glasses positioning belt 3 passes through the limiting ring belt 7, so as to realize the binding and limiting of the windproof glasses binding belt 2, and the identification position is placed on various official required logos or desired patterns. Example 3

[0027] The connecting structure is a pin 8, which fixes the top of the glasses positioning belt 3. A cavity 11 capable of accommodating the insertion of the pin 8 is provided inside the shell 4. A baffle 12 is movably provided in the cavity 11. A plug-in column 13 is provided on one side of the baffle 12. A slot 16 capable of accommodating the plug-in column 13 is provided on the side wall of the pin 8. A spring 14 is provided between the side of the baffle 12 away from the plug-in column 13 and the inner end wall of the cavity 11. A slide groove 15 is provided on the surface of the shell 4. A push plate 9 fixedly connected to the baffle 12 is slidably embedded in the slide groove 15. The pin 8 is inserted into the cavity 11 on the shell 4 to press the spring piece 17. The elastic force of the spring 14 pushes the baffle 12 to make the plug-in column 13 inserted into the slot 16 on the pin 8, thereby limiting the pin 8 from detaching from the shell 4, thereby realizing the connection between the glasses positioning belt 3 and the shell 4, which is used to limit the binding of the windproof glasses binding belt 2.

[0028] Furthermore, in the present embodiment, a spring sheet 17 is provided inside the cavity 11, and the spring sheet 17 is aligned with the pin 8. When the pin 8 is inserted into the shell 4, the pin 8 presses against the spring sheet 17 to elastically expand. After the push plate 9 is pushed to drive the baffle 12 away from the pin 8 so that the plug-in column 13 is disengaged from the slot 16, the pin 8 can automatically pop out of the shell 4 under the elastic force of the spring sheet 17, and the operation is more convenient.

[0029] Working principle: when in use, by setting the glasses positioning belt 3 and the shell cover 4 at the rear end of the safety helmet 1, when the windproof glasses are idle, push the windproof glasses restraining belt 2 to move above the shell cover 4, and then pull the top of the glasses positioning belt 3 to connect with the shell cover 4 using the connecting structure, so that the windproof glasses restraining belt 2 can be restrained and limited at the rear end of the safety helmet 1, to prevent the windproof glasses restraining belt 2 from loosening and causing the windproof glasses to slip during riding with the safety helmet 1. The support block 18 at the top of the shell cover 4 and the convex ridge 19 set on the side of the support block 18 can limit the windproof glasses restraining belt 2 and enhance the restraining effect of the windproof glasses restraining belt 2. Furthermore, when the connecting structure is a letter lock buckle 6, only the glasses positioning belt 3 needs to be tightened. The sub-buckle at the top of the belt 3 is buckled with the female buckle on the shell 4, which is used for limiting the binding of the windproof glasses' binding strap 2; when the connecting structure is a limiting ring belt 7, the top of the glasses' positioning belt 3 passes through the limiting ring belt 7 to achieve the binding of the windproof glasses' binding strap 2. When the connecting structure is a pin 8, the pin 8 is inserted into the cavity 11 on the shell 4 to press the spring piece 17. The elastic force of the spring 14 pushes the baffle 12 to make the plug-in column 13 insert into the slot 16 on the pin 8, limiting the pin 8 from being separated from the shell 4, thereby achieving the connection between the glasses' positioning belt 3 and the shell 4, which is used for limiting the binding of the windproof glasses' binding strap 2. The above technical scheme has a reasonable structure, can achieve the binding of the idle windproof glasses' binding strap 2, and is simple to operate and highly practical.

[0030] All technical features in this embodiment can be freely combined according to actual needs.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
