[0006] To solve the above technical problems, the technical scheme of the utility model is: a rescue helmet with goggle adjusting device, which comprises a cap shell and a goggle assembly capable of being fixed on the cap shell, a left guide rail is fixedly installed on the left side of the cap shell, a right guide rail is fixedly installed on the right side of the cap shell, the goggle assembly comprises a goggle main body, a left connecting rope, a right connecting rope and a rope belt adjuster, the left connecting rope and the right connecting rope are both non-elastic ropes, the rope belt adjuster comprises a base and a knob installed on the base, the base is fixedly installed on the cap shell, one end of the left connecting rope is fixedly connected with the left end of the goggle main body, the other end of the left connecting rope passes through the gap between the left guide rail and the cap shell and is connected with the knob of the rope belt adjuster, one end of the right connecting rope is fixedly connected with the right end of the goggle main body, the other end of the right connecting rope passes through the gap between the right guide rail and the cap shell and is connected with the knob of the rope belt adjuster; the rope belt adjuster has a one-way locking function, when the rope belt adjuster is in the locking mode, the knob can only rotate in one direction and can wind the left connecting rope and the right connecting rope, so that the goggle main body can be tightly buckled on the cap shell or cover the eyes of the user, when the rope belt adjuster is in the release mode, the left connecting rope and the right connecting rope can be lengthened outward under the action of external force, so that the goggle main body can be moved away from the cap shell or the eyes of the user.

[0007] In the above technical scheme, the goggle assembly is combined by the left connecting rope, the right connecting rope and the rope belt adjuster to replace the traditional elastic band, the rope belt adjuster can easily realize the tightening and lengthening of the rope belt, and since the left connecting rope and the right connecting rope are both non-elastic ropes, the problem that the traditional elastic band gradually loses elasticity does not occur, so that the stability and reliability of the goggle wearing can be ensured, and the goggle can be very conveniently and stably fixed on the cap shell when not needed to be worn.

[0008] In an embodiment, the base is located behind the left guide rail and integrated with the left guide rail as a whole, a through hole is arranged between the base and the left guide rail to pass the left connecting rope; or the base can also be arranged behind the right guide rail and integrated with the right guide rail as a whole, a through hole is arranged between the base and the right guide rail to pass the right connecting rope. The base is integrated with the left guide rail or the right guide rail, so that the base does not need to be fixed separately and the structure of the cap shell does not need to be changed, and the integrated structure can also very conveniently upgrade the existing rescue helmet.

[0009] In an embodiment, the rope belt adjuster can be switched between the locking mode and the release mode by changing the axial position of the knob.

[0010] In an embodiment, the rope belt adjuster is a rotary button. The rotary button is a relatively mature product in the prior art and is usually used on the shoelace of a shoe.

[0011] In one embodiment, both the left connecting rope and the right connecting rope are nylon steel wire ropes.

[0012] In one embodiment, the left and right connecting ropes are connected to the goggle body via fasteners. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0018] like Figure 1 , 2 As shown, a rescue helmet with a goggle adjustment device includes a helmet shell 1 and a goggle assembly that can be fixed to the helmet shell 1. A left guide rail 2 is fixedly installed on the left side of the helmet shell 1, and a right guide rail is fixedly installed on the right side of the helmet shell 1 symmetrically. The goggle assembly includes a goggle body 3, a left connecting rope 4, a right connecting rope 5, and a rope adjuster. Both the left connecting rope 4 and the right connecting rope 5 are non-elastic ropes. The rope adjuster includes a base 6 and a knob 7 installed on the base 6. The base 6 is fixedly installed on the helmet shell 1. One end of the left connecting rope 4 is fixedly connected to the left end of the goggle body 3, and the other end of the left connecting rope 4 passes through the gap between the left guide rail 2 and the helmet shell 1 and is adjusted by the rope. The knob 7 of the adjuster is connected, and one end of the right connecting rope 5 is fixedly connected to the right end of the goggle body 3. The other end of the right connecting rope 5 passes through the gap between the right guide rail and the cap shell 1 and is connected to the knob 7 of the rope adjuster. The rope adjuster has a one-way locking function. When the rope adjuster is in the locking mode, the knob 7 can only rotate in one direction and can retract the left connecting rope 4 and the right connecting rope 5, so that the goggle body 3 can be tightened on the cap shell 1 or cover the user's eyes. When the rope adjuster is in the release mode, the left connecting rope 4 and the right connecting rope 5 can be stretched outward under the action of external force, so that the goggle body 3 can be moved away from the cap shell 1 or the user's eyes.

[0019] In the embodiment, the rope adjuster is a rotary button, the base 6 of the rope adjuster is located at the rear of the left rail 2 and integrated with the left rail 2 as a whole, and a through hole is arranged between the base 6 and the left rail 2 to pass the left connecting rope 4. The rotary button is a relatively mature product in the prior art and is usually used on the shoelace of a shoe. The rotary button can switch the rope adjuster between the locking mode and the release mode by changing the axial position of the knob 7.

[0020] In order to ensure the strength of the left connecting rope 4 and the right connecting rope 5, in the embodiment, the left connecting rope 4 and the right connecting rope 5 are both nylon steel ropes with a diameter of 1 mm and a breaking tension greater than 30 kgf, and the left connecting rope 4 and the right connecting rope 5 are connected to the goggle body 3 through the fastener 8.

[0021] In the embodiment, the goggle assembly is combined by the left connecting rope 4, the right connecting rope 5 and the rope adjuster to replace the traditional elastic band, wherein the rope adjuster can easily realize the tightening and lengthening of the rope, and since the left connecting rope 4 and the right connecting rope 5 are both non-elastic ropes, the problem that the elastic force of the traditional elastic band gradually weakens does not occur, so that the stability and reliability of the goggle when worn can be ensured, and the goggle can be very conveniently and stably fixed on the hat shell when not needed to be worn. Since the base 6 is integrated with the left rail 2, the base 6 does not need to be fixed separately, and the structure of the hat shell 1 does not need to be changed, and the integrated structure can also very conveniently upgrade the existing rescue helmet.

[0022] The above embodiment is a preferred implementation scheme of the utility model, in addition to this, the utility model can also be realized in other ways, and any obvious replacement without departing from the technical scheme concept is within the scope of the utility model patent.

[0023] In order to make the person skilled in the art more conveniently understand the improvement of the utility model relative to the prior art, some drawings and descriptions of the utility model have been simplified, and some other elements are also omitted in the application file for the sake of clarity, and the person skilled in the art should realize that these omitted elements can also constitute the content of the utility model.
