Description

Technical Field

[0001] This utility model relates to the field of helmet technology, and in particular to a side-lock adjustable helmet. Background Technology

[0002] Helmets are essential everyday items, and can be divided into full-coverage and partial-coverage helmets. Full-coverage helmets protect the entire head, including the chin, while partial-coverage helmets only protect the head and are secured with a strap. Most electric bike and bicycle riders typically choose partial-coverage helmets, especially suitable for use in the hot summer. However, because only the chin is secured with a strap, there is a lack of protection for the jaw and mouth. In the event of a sudden stop, braking, or an accident, the chin and lips are easily injured, making it less safe. Most importantly, the conventional method of securing a partial-coverage helmet by fastening the chin with a strap, and adjusting the strap length, usually by bending and retracting, is not only difficult to adjust but also prone to loosening and not securing properly. This results in the helmet becoming loose and unstable, which is very inconvenient. Furthermore, after putting on the helmet, both hands are needed to tighten the chin and make minor adjustments for comfort, which is time-consuming, laborious, and inconvenient. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a side-lock adjustable helmet. It tightens the strap by side locking and can slide up and down to adjust the tightness of the strap. It is efficient, quick and easy to operate and has higher stability.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0005] A side-lock adjustable helmet includes a helmet body, straps, protective rings installed on both sides of the helmet body, and a sliding self-locking mechanism disposed on one side of the protective rings;

[0006] The protective ring is adapted to provide protection for the chin and lips at the front;

[0007] The sliding self-locking mechanism includes a slide rail seat disposed on one side of the protective ring and a slider slidably assembled in the slide rail seat;

[0008] One end of the strap is fixed to the side of the helmet away from the sliding self-locking mechanism, and the other end of the strap is connected to the inner side of the slider by a buckle.

[0009] Pushing the slider can adjust the tightness of the strap, and the slider can self-lock and fix its position under normal conditions.

[0010] In this embodiment, a toothed groove is provided inside the slide rail seat along the sliding direction of the slider, and a row of one-way locking teeth is provided in the toothed groove;

[0011] A push block is slidably mounted on the slider along the direction perpendicular to the slider's sliding movement. The push block is elastically mounted and a wedge-shaped locking block is provided on the side near the tooth groove. The wedge-shaped locking block and the one-way locking tooth engage in a one-way manner.

[0012] In this embodiment, a first spring is provided between the slider and the slide rail seat, and a second spring is provided between the push block and the slider.

[0013] In this embodiment, a dial is provided on the outside of the push block.

[0014] In this embodiment, a push handle is provided on the outside of the slider.

[0015] The buckle in this embodiment includes a female buckle disposed at one end of the strap and a female buckle disposed inside the slider.

[0016] In this embodiment, the slide rail seat is provided with a T-shaped slide groove suitable for assembling the slider.

[0017] In this embodiment, a dovetail groove suitable for assembling a push block is provided on the outer side of the slider.

[0018] In this embodiment, a dust cover is also provided on the outside of the slide rail seat.

[0020] By adopting the above technical solution, this utility model has the following beneficial effects:

[0021] 1. This utility model, through the flip-mounted protective ring, can protect the chin and lips, as well as the cheeks and teeth, while riding, reducing impact and minimizing injury in sudden situations, thus enhancing safety.

[0022] 2. This utility model uses a side sliding self-locking mechanism, which combines a strap fixed at one end and assembled with a buckle and a slider at the other end. This allows the tightness of the strap to be adjusted by directly pushing the slider. The operation is efficient, quick, convenient and labor-saving. The slider can self-lock and fix the strap, so it will not loosen and the overall wearing stability is higher.

[0023] 3. This utility model utilizes a row of one-way locking teeth within the slide rail base, along with a push block that is laterally elastically mounted on the slider and a wedge-shaped locking block on the side wall of the push block. This design ensures that when the slider is pushed upwards for adjustment, each time the push block is engaged with the wedge-shaped locking block by the second spring, thus creating a self-locking mechanism to fix the slider's position. This prevents the strap from becoming loose once adjusted, resulting in greater stability during wear.

[0024] 4. By setting a first spring between the slider and the slide rail seat and a second spring between the slider and the push block, the push block can be pushed open before each use to disengage the wedge-shaped locking block from the one-way locking teeth, thereby allowing the slider to return to its loosest state under the action of the first spring. This makes it convenient to adjust the slider from bottom to top and readjust the tightness of the belt.

[0025] 5. This utility model, through the buckle between the strap and the slider, and the adjustable height of the slider, allows people to control the tightness of the strap by simply fastening it with one hand and adjusting the slider with the other hand when wearing a helmet. It is convenient, quick, and saves time and effort. Attached Figure Description

[0035] To make the content of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0036] like Figure 1-8 As shown, this embodiment provides a side-lock adjustable helmet, which mainly consists of a helmet body 1, a strap 3, a protective ring 2, and a sliding self-locking mechanism 4. The protective ring 2 is rotatably mounted on both sides of the helmet body 1. The protective ring 2 can be flipped to the front to rest between the chin and mouth, providing protection for the chin and lips. Alternatively, the protective ring 2 can be made in a fixed style with a slight gap between it and the chin and mouth, still providing protection. The main body of the protective ring 2 can be made of hard materials such as plastic, and soft sponge or cotton cloth is provided on the inner side of the protective ring 2 to make it more comfortable to wear and better protect the chin, lips, teeth, and cheeks.

[0037] To facilitate tightening the chin strap 3 and ensure stable wearing of the helmet 1, a sliding self-locking mechanism 4 is provided on one side of the protective ring 2 in this embodiment. The sliding self-locking mechanism 4 includes a slide rail seat 40 fixed on one side of the protective ring 2 and a slider 41 slidably assembled within the slide rail seat 40. One end of the strap 3 is fixed to the side of the helmet 1 away from the sliding self-locking mechanism 4, and the other end of the strap 3 is connected to the inside of the slider 41 via a buckle. Specifically, the buckle consists of a male buckle 5 and a female buckle 6. The male buckle 5 is located at one end of the strap 3, and the female buckle 6 is located inside the slider 41. Inserting the male buckle 5 at one end of the strap 3 into the female buckle 6 will lock it in place, and pressing the female buckle 6 will disengage the male buckle 5, thus enabling the use of the strap 3. Simultaneously, pushing the slider 41 adjusts the tightness of the strap 3. The slide rail 40 has a central through hole; as the slider 41 slides up and down, one end of the strap 3 moves up and down along with the buckle 6 and the slider 41, thus changing the overall tightness of the strap 3. Furthermore, the slider 41 can self-lock in place under normal conditions. This allows for direct adjustment of the strap 3's tightness by pushing the slider 41, making operation efficient, quick, convenient, and labor-saving. The self-locking mechanism of the slider 41 prevents the strap from loosening, resulting in higher overall wearing stability.

[0038] To achieve self-locking of the slider 41 at any time, a toothed groove 402 is provided in the slide rail seat 40 of this embodiment along the sliding direction of the slider 41, and a row of one-way locking teeth 43 is provided in the toothed groove 402. A push block 42 is slidably mounted on the slider 41 in a direction perpendicular to the sliding direction of the slider 41. A second spring 46 is provided between the push block 42 and the slider 41. A wedge-shaped locking block 44 is also provided on the side of the push block 42 near the toothed groove 402. The wedge-shaped locking block 44 engages with the one-way locking teeth 43 in one direction. In this way, when the slider 41 is pushed upward for adjustment, the push block 42 can make the wedge-shaped locking block 44 engage with the one-way locking teeth 43 under the action of the second spring 46 each time, thereby forming a self-locking and fixing the position of the slider 41. This way, the strap 3 will not loosen after being adjusted to the correct position, making it more stable when worn.

[0039] Specifically, in this embodiment, a first spring 45 is provided between the slider 41 and the slide rail seat 40, and a second spring 46 is provided between the push block 42 and the slider 41. Thus, before each use, the push block 42 can be pushed open to disengage the wedge-shaped locking block 44 from the one-way locking tooth 43, thereby allowing the slider 41 to return to its loosest state under the action of the first spring 45, which facilitates the adjustment of the slider 41 from bottom to top and the readjustment of the tightness of the strap 3.

[0040] To facilitate one-handed operation of the push block 42, a dial 421 is provided on the outer side of the push block 42 in this embodiment. To facilitate one-handed pushing of the slider 41, a push handle 412 is provided on the outer side of the slider 41. Thus, through the buckle between the strap 3 and the slider 41, and the vertical adjustment of the slider 41, when wearing the helmet, the user only needs to fasten the strap 3 with one hand and adjust the slider 41 with the other hand to control the tightness of the strap 3, which is convenient, quick, and saves time and effort.

[0041] To ensure the stability of the mechanism, a T-shaped groove 401 suitable for assembling the slider 41 is provided in the slide rail seat 40 of this embodiment. The slider 41 is also T-shaped, making the sliding more stable and preventing it from falling off. At the same time, a dovetail groove 411 suitable for assembling the push block 42 is provided on the outside of the slider 41. The push block 42 is also dovetail-shaped, making the sliding more stable and preventing it from falling off.

[0042] In order to protect the sliding self-locking mechanism 4 and prevent dust and water, and also to serve an aesthetic purpose, a dust cover 7 is provided on the outside of the slide rail seat 40 in this embodiment. The dust cover 7 is assembled by a rotating shaft, can be opened and closed by flipping, and is fixed by magnetic adsorption.
