Abstract
Description
Technical Field
[0001] This utility model relates to the field of helmet technology, and more specifically, to a helmet with an inner lining structure. Background Technology
[0002] The demand for helmets covers daily life, occupational protection, and special fields. In the sports field, high-risk activities such as cycling, skiing, and motorcycling rely on the energy-absorbing properties of helmets, which serve as key equipment for head protection. In the industrial field, scenarios such as construction and mining require helmets to withstand falling objects and collisions. The technological development and application scenarios of helmets are closely centered around safety and comfort.
[0003] In existing technologies, the inner lining of helmets is fixedly attached to the inside of the helmet. This means that the inner lining cannot be removed for replacement or cleaning. As a result, the inner lining accumulates a large amount of dust and sweat stains over time, and the environment inside the lining is prone to bacterial growth, which can have a certain impact on human health. Currently, the cushioning pad inside the helmet lining is made of sponge. After developing odors and getting dirty, the sponge will deteriorate after a few washes, resulting in a short lifespan for the sponge lining. At the same time, the sponge lining absorbs water and sweat, and is prone to mold growth and odors in a humid environment over a long period of time. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] In view of the problems existing in the prior art, the present invention provides a helmet with an inner lining structure to solve the technical problems mentioned in the background art.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: a helmet with an inner lining structure, comprising a helmet body, an inner lining frame on the helmet body, an mounting rod on the inner lining frame, an mounting sleeve on the helmet body, a snap-fit block rotatably mounted on the mounting sleeve via a torsion spring, the snap-fit block being fan-shaped, and symmetrical snap-fit grooves cooperating with the snap-fit block being provided on the mounting rod, a waterproof inner lining inside the inner lining frame, the waterproof inner lining comprising a first fabric and a second fabric, a waterproof membrane being provided between the first fabric and the second fabric, and a sponge being provided inside the waterproof membrane.
[0008] The present invention is further configured such that the mounting rod is provided with a reset groove, the reset groove is provided with a reset plate, and the reset plate is symmetrically provided with reset rods. The reset plate facilitates the squeezing of the locking block and disassembling of the mounting rod.
[0009] The present invention is further configured such that a reset screw is rotatably provided on the reset groove, and the reset screw is threadedly connected to the reset plate, thereby facilitating the movement of the mounting plate and the mounting rod.
[0010] The present invention is further provided that the bottom of the reset screw is provided with a cross groove, which facilitates the rotation of the reset screw.
[0011] The present invention is further provided with an adhesive between the sponge and the waterproof membrane, the adhesive being bonded to both the sponge and the waterproof membrane respectively, which facilitates the connection between the sponge and the waterproof membrane.
[0012] The present invention is further provided with Velcro on the second fabric and the inner lining frame, so as to facilitate the installation of the waterproof lining on the inner lining frame.
[0013] The present invention is further configured such that the inner liner frame is provided with a positioning block and the helmet body is provided with a positioning groove, which facilitates the positioning and installation of the inner liner frame.
[0014] The present invention is further provided that the top of the inner lining frame is provided with a head cushioning strap and a head cushioning pad, which facilitates the support of the waterproof inner lining and also facilitates the cushioning support of the head.
[0015] (III) Beneficial Effects
[0016] Compared with the prior art, the present invention provides a helmet with an inner lining structure, which has the following beneficial effects:
[0017] 1. The torsion spring causes the locking block to extend into the locking groove, fixing the position of the mounting rod and the mounting sleeve, which facilitates the installation of the inner liner frame on the helmet body. The reset screw drives the reset plate and reset rod to move, which facilitates the movement of the locking block, thereby facilitating the removal, installation and replacement of the inner liner frame.
[0018] 2. By setting a first fabric, a second fabric, and a waterproof membrane on the outside of the sponge, the service life of the helmet's waterproof liner can be improved. When washed, the sponge is wrapped in the waterproof membrane, so it will not rot. Without affecting comfort, it also prevents the sponge from absorbing a lot of sweat, which can lead to mold and serious odor problems.
[0019] 3. The use of Velcro makes it easy to install the waterproof liner on the liner frame. The use of head cushioning straps and head cushioning pads makes it easy to support the waterproof liner and provide cushioning support for the head. Attached Figure Description
