Description
Technical Field
[0001] This application relates to the field of glove technology, and more particularly to a double-layer protective glove. Background Technology
[0002] Gloves are wearable equipment that covers the hands (one finger or the entire finger) to protect the user's hands through physical isolation or functional design. Common protective gloves are mostly single-layer designs, such as... Figure 3 As shown, during the manufacturing process, two layers of fabric (the specific material is determined according to the usage environment; for example, if it is mainly used to resist the cold, the selected fabric can be leather, and if it is mainly used to protect the hands of workers during labor, the selected fabric can be breathable canvas) are pressed together and their edges are sewn together.
[0003] However, this simple single-layer design offers limited protection for the user's hands. Once the hands are damaged during work, the risk of injury from dangerous objects in the external environment increases significantly. Utility Model Content
[0004] This application provides a double-layer protective glove that can effectively improve the protection of the user's hands.
[0005] The above-mentioned objective of this application is achieved through the following technical solution:
[0006] A double-layer protective glove includes a first protective layer and a second protective layer. The outline of the first protective layer is similar to that of an ordinary person's hand. The overall shape of the second protective layer is geometrically similar to that of the first protective layer, and the dimensions of both are proportionally enlarged by a fixed proportional coefficient k (k>1).
[0007] The first protective layer is embedded inside the second protective layer and the two are detachably connected together by a fixing module installed on the outside of the wrist of the first protective layer. The materials used in the second protective layer and the first protective layer are both capable of protecting the user's hand from damage caused by objects in the external environment.
[0008] Each finger sleeve of the second protective layer has an elastic contraction part at one of the finger joints. The elastic contraction part is used to tighten the first and second protective layers with the corresponding finger of the user after the user puts on the gloves.
[0009] Furthermore, the second protective layer is made of UHMWPE fiber.
[0010] Furthermore, the first protective layer is made of aramid fiber felt.
[0011] Furthermore, the aramid fiber felt selected in the first protective layer has a needle-punching density of 400 needles / cm².2 .
[0012] Further, the second protective layer wrist part is provided with a split opening for avoiding the fixed module at a position corresponding to the fixed module on the first protective layer wrist part.
[0013] Further, the fixed module comprises a sub fastener, one end of the sub fastener is installed on the outer side of the first protective layer wrist part through a first binding rope, the lower side of the first binding rope is provided with a second binding rope, and one end of the second binding rope is also installed on the outer side of the first protective layer wrist part, and the length of the second binding rope is not less than the circumference of the second protective layer wrist part.
[0014] Further, the elastic contraction part is a ring-shaped elastic rope, and the diameter of the ring-shaped elastic rope in normal state is less than the maximum diameter of the finger joint at the corresponding position when a normal person wears a glove.
[0015] Further, the seam edge part of the first protective layer and the second protective layer is spliced by using a triangular needle method.
[0016] In summary, the present application has at least one of the following beneficial technical effects:
[0017] The glove of the present application is composed of a first protective layer and a second protective layer, and the materials of the first protective layer and the second protective layer both satisfy the function of resisting damage to the user's hands from the external environment after the user wears the first protective layer and the second protective layer on the hands. In this way, even if the second protective layer on the outside is worn out after the user wears the glove of the present application on the hands, the first protective layer of the present application can temporarily protect the user's hands, so that the user's hands are not accidentally injured in the process of work due to the damage of the second protective layer when the user does not find the damage of the second protective layer in time or does not have the condition to replace a new glove. In addition, the first protective layer and the second protective layer of the present application are connected together through the fixed module after being worn on the user's hands, so that the user only needs to replace the damaged second protective layer when the conditions are met subsequently, which can reduce the use cost of the glove. The elastic contraction part added at each finger sleeve of the second protective layer can ensure that the second protective layer and the first protective layer are tightly attached to the user's hands when the user works with the glove of the present application.

[0026] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application are described clearly and completely below. Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor also belong to the scope of protection of the present application.
[0027] As shown in Figure 1 and Figure 2 , a double-layer protective glove disclosed by the present application includes a first protective layer 1 and a second protective layer 2. The first protective layer 1 has a shape similar to that of a common human hand. The second protective layer 2 has a geometric similar relationship with the overall shape of the first protective layer 1, and the dimensions of the two are enlarged by a fixed proportional coefficient k (k>1).
[0028] The first protective layer 1 is embedded in the second protective layer 2 and detachably connected together through the fixing module 3 mounted outside the wrist of the first protective layer 1, and the materials used by the second protective layer 2 and the first protective layer 1 have the function of resisting the damage of external objects to the user's hands.
[0029] One of the knuckles on each finger sleeve of the second protective layer 2 is provided with an elastic contraction part 4, which is used to tighten the first protective layer 1 and the second protective layer 2 with the corresponding finger part of the user after the user wears the glove.
[0030] In the above embodiment, the outline of the first protective layer 1 and the second protective layer 2 of the present application is similar to that of an ordinary human hand, and the size ratio coefficient k of each dimension of the second protective layer 2 to the corresponding dimension of the first protective layer 1 is preferably 1.15, that is, the size of each dimension of the second protective layer 2 is enlarged by 1.15 times on the basis of the corresponding size of each dimension of the first protective layer 1. Based on this size ratio coefficient, not only is it convenient to embed the first protective layer 1 into the second protective layer 2, but also it can prevent the gap between the first protective layer 1 and the second protective layer 2 from being too large, which affects the actual experience of the user's hands during work.
[0031] When the glove of the present application is used, the first protective layer 1 is in direct contact with the user's hands, and the second protective layer 2 is located outside the first protective layer 1. The wrist of the first protective layer 1 and the second protective layer 2 is detachably connected together through the fixing module 3, and the finger sleeve of the first protective layer 1 and the second protective layer 2 is tightened on the user's fingers through the elastic contraction part 4 on the second protective layer 2. In this way, the first protective layer 1 and the second protective layer 2 can both maintain a close relationship with the user's hands during use, which can reduce the risk of glove loosening during work and effectively improve the actual wearing experience of the user. Since the materials of the first protective layer 1 and the second protective layer 2 both have the function of resisting the damage of external objects to the user's hands (i.e., the materials of the first protective layer 1 and the second protective layer 2 have a certain toughness and strength, and when the user contacts some sharp or sharp objects, these objects can be prevented from penetrating into the inside of the glove), even if the second protective layer 2 is accidentally damaged during work, the first protective layer 1 of the present application can temporarily protect the user's hands, so that the user's hands are not accidentally injured due to the damage of the second protective layer 2 when the user does not discover the damage of the second protective layer 2 in time or does not have the condition to replace a new glove. In addition, the first protective layer 1 and the second protective layer 2 of the present application are detachably connected together through the fixing module 3 after being worn on the user's hands, so that the user only needs to replace the damaged second protective layer 2 when conditions permit, and therefore the modular design of the glove of the present application can also reduce the use cost of the glove.
[0032] Further, the material of the second protective layer 2 is UHMWPE fiber.
[0033] In the above embodiment, UHWMPE is a kind of ultra-high performance polyethylene material with very high tensile strength, elongation at break, wear resistance, corrosion resistance and excellent self-lubricating performance. The tensile strength of UHWMPE can reach 8.9 GPa, and the elongation at break can reach more than 600%. The wear resistance of this material is about 10 times higher than that of polyurethane and about 2 times higher than that of polycarbonate. This material has been applied in the existing technology of marine fishing nets. The material is used to prepare the first protective layer 1 of the present application. The excellent tensile strength and wear resistance of the material can resist sharp or sharp objects in the working environment of the user, and the first protective layer 1 can effectively improve the service life of the glove and reduce the replacement frequency of the glove.
[0034] Further, the material of the first protective layer 1 is aramid fiber felt.
[0035] In the above embodiment, aramid fiber felt is a non-woven fabric material made of aramid fiber (aromatic polyamide fiber) through needle punching, wet laying and other processes. This material also has excellent impact resistance. Although the tensile strength is not as high as UHWMPE, it is about 5-6 times the tensile strength of steel wire. It is commonly used to make fireproof gloves or cable sheaths in the existing technology. The material can work with the second protective layer 2 to block sharp or sharp objects in the environment from piercing the user's hand when used normally. When the second protective layer 2 is accidentally worn out, the material can temporarily take on the protective task of the first protective layer 1 due to its good tensile strength and wear resistance, reducing the risk of direct contact between the user's hand and the sharp or sharp objects in the environment when the second protective layer 2 is worn out.
[0036] Further, the needle punching density of the aramid fiber felt selected in the first protective layer 1 is 400 stitches / cm 2 .
[0037] In the above embodiment, according to existing experimental research, when aramid fiber felt is prepared by needle punching, the air permeability and mechanical properties of the aramid fiber felt reach the best balance when the main needle punching density is controlled at 300-400 stitches / cm². The fibers in the aramid fiber felt prepared under this condition are not only fully entangled but also have stable pore structure. The best air permeability appears near the needle punching density of 400 stitches / cm², and the approximate air permeability can reach about 19 m³ / (m²·min). The needle punching density of the first protective layer 1 in the present application is preferably 400 stitches / cm 2 , which can ensure the strength of the first protective layer 1 while also providing good air permeability. This can improve the comfort of the user's hand after wearing the glove of the present application.
[0038] Further, as shown in Figure 1 the second protective layer 2 wrist is provided with a split opening 5 for avoiding the fixed module 3 at the position corresponding to the fixed module 3 on the first protective layer 1 wrist.
[0039] In the above embodiment, the split opening 5 provided on the side of the second protective layer 2 wrist in the above manner can facilitate the user to avoid the fixed module 3 on the first protective layer 1 when wearing the second protective layer 2 on the first protective layer 1.
[0040] Further, as shown in Figure 1 and Figure 2 the fixed module 3 includes a sub-buckle 31, one end of the sub-buckle 31 is installed on the outside of the first protective layer 1 wrist through a first binding rope 32, the lower side of the first binding rope 32 is provided with a second binding rope 33, and one end of the second binding rope 33 is also installed on the outside of the first protective layer 1 wrist, the length of the second binding rope 33 is not less than the circumference of the second protective layer 2 wrist.
[0041] In the above embodiment, the lower side of the first binding rope 32, i.e. the side towards the palm of the glove, the sub-buckle 31 on the first binding rope 32 is a sun-shaped buckle, and the length of the second binding rope 33 is not less than the circumference of the second protective layer 2 wrist. In this way, after the user wears the first protective layer 1 and the second protective layer 2 on the hand, the second binding rope 33 can be passed through the sub-buckle 31 after being wound around the wrist of the second protective layer 2 from the outside, and by further adjusting the distance between the free end of the second binding rope 33 and the sub-buckle 31, the second binding rope 33 can be tightened outside the second protective layer 2, thereby achieving the effect of tightening the wrist of the second protective layer 2 and the wrist of the first protective layer 1 on the user's wrist. When the glove needs to be taken off later, the user only needs to remove the second binding rope 33 from the sub-buckle 31, or when the user only wants to wear the first protective layer 1, the user can simply use the second binding rope 33 and the sub-buckle 31 to fix the wrist of the first protective layer 1 on his own wrist. In this way, the user can not only freely disassemble and combine the gloves according to needs (for example, when using in a cold and dangerous outdoor environment, the user can wear both the first protective layer 1 and the second protective layer 2 on the hand, and when using in a hot but not highly dangerous outdoor environment, the user can only wear the first protective layer 1 with good air permeability on the hand), but also can flexibly assemble and replace when the first protective layer 1 or the second protective layer 2 has a problem, thereby reducing the use cost.
[0042] Further, as shown in Figure 1 the elastic contraction part 4 is a ring-shaped elastic rope, and the diameter of the ring-shaped elastic rope in the normal state is less than the maximum diameter of the corresponding finger joint of a normal person when wearing a glove.
[0043] In the above embodiment, one annular elastic rope is fixedly stitched on each of the five finger sleeves of the second protective layer 2, and the annular elastic rope corresponds to one joint position on the corresponding finger of an ordinary person, for example, when the user wears the second protective layer 2, the annular elastic rope on each finger sleeve is just sleeved on the second joint of the corresponding finger of the user. Since the diameter of the annular elastic rope in the normal state is smaller than the maximum diameter of the joint of the corresponding finger of the user, when the user wears the second protective layer 2, the annular elastic rope will use the elastic force generated by the user's finger to expand the annular elastic rope to tightly clamp the finger sleeves of the second protective layer 2 and the first protective layer 1 on the corresponding joint of the user. The upper and lower sides of the joint are the finger pads with larger diameters, so that the close contact effect between the first protective layer 1 and the second protective layer 2 and between the first protective layer 1 and the user's hand is improved, and the risk of the entire glove falling off the user's hand is reduced. In the subsequent process of separating the glove from the user's hand, the user only needs to pull out the finger with force.
[0044] Further, as shown in Figure 6 , the edges of the first protective layer 1 and the second protective layer 2 are stitched with a triangular needle method.
[0045] In the above embodiment, as shown in Figure 3 and Figure 4 , it is the general state of the glove after the edges of the two pieces of hand-shaped cloth are stitched. The stitching position of the edge of the cloth is the seam 6, which is located inside the glove when worn. The manufacturing method of the first protective layer 1 and the second protective layer 2 of the present application is similar to the manufacturing method of the common glove. If the seam 6 of the present application is consistent with the seam 6 of the edge of the glove in the prior art, it is likely that the user will feel uncomfortable in the contact area between the finger and the seam 6 during wearing. In order to solve this problem and improve the wearing experience of the user wearing the glove of the present application, as shown in Figure 5 , the seam 6 of the edge of the first protective layer 1 and the second protective layer 2 is split, and as shown in Figure 6 , the edges are respectively stitched on the inner side of the seam 6 of the first protective layer 1 and the second protective layer 2 by using a triangular needle method (which is commonly used in the clothing industry to process cuffs and pant legs). This can effectively improve the comfort of the user during wearing.
[0046] The implementation principle of the embodiment is that before outdoor work, the user can first wear the first protective layer 1 on the hand, then wear the second protective layer 2 on the first protective layer 1, and ensure that each finger is fully inserted into each finger sleeve of the second protective layer 2 during wearing, so that the annular elastic rope in the second protective layer 2 can tighten the second protective layer 2 and the first protective layer 1 on the user's hand. After the above operation, the user can pinch the free end of the second binding rope 33 of the wrist of the first protective layer 1 from the forked opening 5 of the second protective layer 2, pull the second binding rope 33 around the wrist of the second protective layer 2, and return to the sub-buckle 31 connected with the first binding rope 32 on the wrist of the first protective layer 1. In this way, the wrist of the first protective layer 1 and the second protective layer 2 can also be tightly fixed to the user's hand, so as to reduce the risk of gloves falling off the user's hand during use. In this way, after the user wears the glove of the application on the hand, even if the second protective layer 2 on the outside is worn out, the first protective layer 1 of the application can temporarily protect the user's hand, so that the user's hand is not injured due to the damage of the second protective layer 2 during work.
[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the application, but not to limit them; although the application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can modify the technical solutions described in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the application.
