Description

Technical Field

[0001] The utility model relates to the technical field of safety helmets, in particular to a safety helmet lining and a connection mechanism with the safety helmet. Background Art

[0002] Safety helmets are widely used to protect people's physical safety in various industries such as construction sites and factories. On construction sites, they are essential work suits for workers. Wearing safety helmets can prevent hidden dangers such as falling objects from high altitude hitting people's heads.

[0003] Safety helmets have different shapes, materials, and even colors due to the needs of different jobs, but their lining structures are roughly the same. Set a few fixed shell sizes, and then set the depth of the lining according to the shell, and the wearer can choose the size that can be worn.

[0004] The existing hard hats generally have a hard hat shell on the outside, a hat lining made of plastic or silicone on the inner lining of the hat shell, and then connected by a nylon lining belt, the nylon lining belt is fixed to the inner wall of the hat shell with rivets, and then a circle of straps is set along the brim of the hat at the bottom of the nylon strap, the front and side of the straps are fixed to the hat shell with rivets, and the rear side is set as an adjustable strap that can be adjusted in tightness. In order to give the adjustable strap a certain adjustment space, the strap at the rear of the hard hat often does not fix it to the hat shell.

[0005] Once such a hat is hit, there is no support point on the back of the hat, and it is not secure enough to wear. In addition, there are many holes on the hat, which reduces the overall bearing capacity of the hat shell and the efficiency of the binding operation is not high. Utility Model Content

[0006] The utility model aims to provide a helmet liner and a connection mechanism with the helmet to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a helmet lining and a connection mechanism with the helmet, comprising a helmet body, a helmet lining and a head circumference strap, wherein the inner wall of the helmet body is evenly distributed with card slots; a lining strap corresponding to the number of the card slots is arranged around the helmet lining, wherein the ends of the lining strap are connected to the card slots by card engagement; a portion of the lining strap passes through the head circumference strap, and a longitudinal limiter is arranged between the lining strap and the head circumference strap, and the lining strap and the head circumference strap are connected transversely by sliding.

[0008] Preferably, six integrally formed lining strips are arranged around the cap lining, and the free ends of the lining strips are fixedly connected with fixing buckles, and the fixing buckles are connected with the card slots by snapping.

[0009] Preferably, the lining belt comprises two corresponding front lining belts, two corresponding side lining belts, and two corresponding rear lining belts.

[0010] Preferably, the front lining strap and the rear lining strap penetrate the head circumference strap, and the longitudinal limiting piece is arranged on the outer wall of the front lining strap and the rear lining strap, and the longitudinal limiting piece is a connecting buckle.

[0011] Preferably, a plurality of longitudinal limit members are longitudinally arranged on the outer wall of the rear lining belt.

[0012] Preferably, a chin strap hanging ear is also provided at the bottom of the fixing buckle connected to the end of the side lining strap.

[0013] Preferably, a connecting seat is provided at the top of the head circumference strap, a connecting opening is provided at the bottom of the connecting seat, the lining strap passes through the connecting opening, a locking groove is provided on the outer wall of the connecting seat, and the locking groove is connected to the longitudinal limit piece by snapping.

[0014] Preferably, a connecting groove is provided on the inner wall of the head circumference strap, and an adjustment belt is provided at the bottom of the connecting groove.

[0015] Preferably, the hat lining, the head circumference strap and the outer wall of the head circumference strap are all provided with ventilation holes.

[0016] Preferably, a non-return buckle is provided on the inner wall of the slot, and a shielding block is provided on the inner end of the slot.

[0017] Compared with the prior art, the utility model has the beneficial effects that the lining of the safety helmet and the connection mechanism with the safety helmet:

[0018] 1. Six slots are evenly distributed on the inner wall of the helmet body, i.e. the shell, and then the lining belt connected to the inner lining is connected to the slots one by one. The lining belt does not need to be fixed to the helmet body with rivets. The helmet body will not be damaged, and its overall structural bearing capacity will not be damaged by punching.

[0019] Second, a connecting seat is arranged above the strap to connect with the lining strap, wherein the head circumference strap and the lining strap can also move horizontally, so that the head circumference strap can adjust the size of the head circumference to a wider range.

[0020] 3. The head circumference strap is only connected to the lining strap and does not need to be fixed separately to the main body of the helmet, so there is no need to punch holes; and the head circumference strap is not fixed by the main body of the helmet at any position. When it is shrunk, it can move directly to the center of the helmet, so there will be no problem of the head shifting to the front of the helmet, making it more secure to wear.

[0021] Fourth, when the head circumference strap is adjusted, it will not move the fixing point of the lining strap, but only move the top of the lining strap slightly closer, thereby changing the depth of the hat lining, making it suitable for more wearers, rather than just the original one-size-fits-all format.

[0022] 5. Multiple rows of connecting buckles are set on the outer wall of the rear lining to further adjust the depth of the hat, so as to avoid the problem of the brim blocking the view of people with small head circumference due to the hat being too deep when wearing it, which is also the reason why the front lining is not adjustable. And the problem of people with large head circumference often falling off due to insufficient depth of the hat when wearing it. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] 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.

[0032] See also Figure 1-7 , the utility model provides a technical solution:

[0033] A helmet lining and a connection mechanism with the helmet, comprising a helmet body 1, a cap lining 2 and a head circumference strap 3, wherein the cap lining 2 is pressed on the surface of the human head, and the top of the cap lining 2 is kept at a certain distance from the helmet body 1. The head circumference strap 3 is sleeved on the outside of the lining strap connected to the cap lining 2, and the head circumference strap 3 is supported by the cap lining 2. The head circumference strap 3 is adjusted to a size matching the head circumference, thereby increasing the wearing comfort.

[0034] The inner wall of the helmet body 1 is evenly distributed with slots 11 for fixing the free ends of the lining straps; the slots 11 should not exceed the brim of the helmet body 1, and the lining straps corresponding to the number of the slots 11 are arranged around the cap lining 2. The free ends of the lining straps are connected with the slots 11 by snapping, and the free ends of the lining straps are snapped into the inner lining of the slots 11, so that the lining straps are fixed.

[0035] It is best to have six lining strips formed integrally with the cap lining 2 around the cap lining 2 , and the free ends of the lining strips are fixedly connected with fixing buckles 25 , and the fixing buckles 25 are connected to the card slot 11 by snapping, and the fixing buckles 25 can be snapped into the inner side of the card slot 11 .

[0036] Part of the lining straps penetrates the head circumference strap 3, that is, the four lining straps near the front and rear sides of the helmet body 1 penetrate the head circumference strap 3, and the head circumference strap 3 is connected with the cap lining 2. A longitudinal limiter is provided between the lining strap and the head circumference strap 3, so that the lining strap and the head circumference strap 3 cannot move longitudinally and staggered at will, so as to avoid the helmet body 1 shaking back and forth when the helmet is worn; at the same time, the lining strap and the head circumference strap 3 can slide horizontally, so that when tightening or expanding the head circumference strap 3, only the inner diameter of the head circumference strap 3 changes, and the center of gravity of the helmet body 1 remains unchanged. Avoid the lining strap and the head circumference strap 3 being fixedly connected, so that the traction lining strap is deformed when adjusting the inner diameter of the head circumference strap 3, so that the helmet body 1 is skewed.

[0037] Specifically, the lining straps include two corresponding front lining straps 21, two corresponding side lining straps 22, and two corresponding rear lining straps 23. The two front lining straps 21 and the two rear lining straps 23 penetrate the head circumference strap 3 and are connected to the head circumference strap 3; while the two side lining straps 22 are directly connected to the card slots 11 on the helmet body 1 without being connected to the head circumference strap 3. This increases the size adjustment range of the rear lining strap 23.

[0038] More specifically, the front lining belt 21 and the back lining belt 23 pass through the connection opening 32 on the head circumference belt 3, and connect the front lining belt 21 and the back lining belt 23 with the head circumference belt 3. And the longitudinal limiter is arranged on the outer wall of the front lining belt 21 and the back lining belt 23, and the longitudinal limiter is a connection buckle 24. The connection buckle 24 can be inserted into the outer wall of the head circumference belt 3 to limit the longitudinal position relationship between the front lining belt 21 and the back lining belt 23 and the head circumference belt 3.

[0039] Two longitudinal limiters are arranged longitudinally on the outer wall of the rear lining band 23, and the longitudinal limiters of different heights are connected to the head circumference band 3 to achieve depth adjustment inside the hat. At the same time, the curvature of the lining band changes accordingly to adapt to more wearers.

[0040] The bottom of the fixing buckle 25 connected to the ends of the two side lining straps 22 is also provided with a chin strap hanging ear 26. The chin strap hanging ear 26 is used for connecting and hanging the chin strap.

[0041] A connection seat 31 is provided at the top of the head circumference strap 3, and the connection seat 31 is integrally formed with the head circumference strap 3 to increase the overall reliability of the head circumference strap 3. The bottom surface of the connection seat 31 is slightly wider than the thickness of the head circumference strap 3, and a connection opening 32 is provided at the bottom of the connection seat 31. The lining strap passes through the connection opening 32 to connect the lining strap to the head circumference strap 3. A locking groove 33 is provided on the outer wall of the connection seat 31, and the locking groove 33 is connected to the longitudinal limiter by snapping. The connection seat 31 has a certain elasticity when used, and the locking groove 33 is shaped like a button hole; the connection buckle 24 can be buckled into the locking groove 33 to fix the connection buckle 24.

[0042] The width of the connecting opening 32 and the locking groove 33 is much larger than the width of the lining belt, so that the lining belt can move laterally in the inner lining of the connecting opening 32. When adjusting the head circumference strap 3, the lining belt position will not be pulled distorted, making it difficult to wear the hat properly.

[0043] The inner wall of the head circumference strap 3 is provided with a connection groove 35 , and the bottom of the connection groove 35 is provided with an adjustment belt 36 for controlling the tightness of the hat.

[0044] The cap lining 2 , the head circumference band 3 and the outer wall of the head circumference band 3 are all provided with ventilation holes 4 .

[0045] The inner wall of the slot 11 is provided with a non-return buckle 12, and the outer wall of the fixed buckle 25 is provided with a groove, which is connected to the non-return buckle 12. When the fixed buckle 25 is inserted into the slot 11, the non-return buckle 12 fixed on the inner wall of the slot 11 will enter the groove on the outer wall of the fixed buckle 25 to prevent the helmet shell from falling off. A shielding block 13 is provided at the inner end of the slot 11, and the shielding block 13 supports the fixed buckle 25 to prevent it from shaking and causing the helmet body 1 to shake.

[0046] The outer wall of the head circumference band 3 is provided with a hook 34, and the outer wall of the head circumference band 3 is wrapped with a breathable cotton pad, and the breathable cotton pad is connected to the hook 34. The breathable cotton pad is fixed by the hook 34, and the breathable cotton pad contacts the human head, so as to avoid the head rubbing of the head by the head circumference band 3, making it more comfortable to wear.

[0047] A cotton lining is provided between the cap lining 2 and the helmet body 1 for wearing in winter to improve the heat preservation effect in winter.
