Description

Technical Field

[0001] The utility model relates to the technical field of protective equipment, in particular to a pair of heat-insulating gloves. Background Art

[0002] The working environment of metallurgical, foundry and furnace workers has very strong heat radiation, generally around 300℃-1000℃. Generally, the hands do not directly touch high-temperature objects during operation, but molten metal may splash occasionally. Gloves are required to be resistant to high temperatures and prevent heat from being transferred from the outside of the gloves to the inside.

[0003] A Chinese patent with announcement number CN209677442U discloses a metallurgical high-temperature resistant heat-insulating glove, which includes a glove body, which includes a first glove layer, a second glove layer and a graphene coating. The first glove layer is provided with a water inlet connecting pipe and a water outlet connecting pipe, and the water inlet connecting pipe and the water outlet connecting pipe are both provided with connectors. The first glove layer is formed by winding a conduit, and the two ends of the conduit are respectively connected to the water inlet connecting pipe and the water outlet connecting pipe. The second glove layer is bonded to the surface of the first glove layer, the second glove layer is an asbestos second glove layer, and the graphene coating is arranged on the surface of the second glove layer.

[0004] With regard to the above-mentioned related technologies, in the prior art, workers set up a conduit to allow water to flow through the inside of the gloves to achieve the effect of heat insulation. However, the gloves are not provided with relevant technical means to tighten the entrance end of the gloves. Therefore, during the work process, the gloves are easily separated from the palms of the workers by external forces, exposing the palms of the workers to the outside, which may cause the workers to be injured and reduce the safety of the heat-insulating gloves. Utility Model Content

[0005] In order to improve the safety of heat-insulating gloves, the present application provides a heat-insulating glove.

[0006] The present application provides heat-insulating gloves using the following technical solutions:

[0007] A heat-insulating glove comprises a glove body, wherein a tightening notch is arranged at the entrance end of the glove body, a tightening assembly is arranged at the tightening notch, the tightening assembly comprises a tightening belt and a connecting closed loop, the connecting closed loop is rotatably connected to one side of the tightening notch, one end of the tightening belt is connected to the other end of the tightening notch, a connecting assembly connected to the other end of the tightening belt is arranged on the glove body, and when the glove body is tightened, the tightening belt passes through the connecting closed loop.

[0008] By adopting the above technical solution, when putting on the glove body, the worker extends his palm into the glove body, then passes the tightening belt through the connection closed loop until the tightening notch is tightened to fit the palm, and finally uses the connection component to connect the tightening belt to the glove body, thereby putting on the glove body. The worker uses the tightening belt and the connection closed loop to adjust the tightening notch, so that the gloves can adapt to the sizes of different workers' hands, so that during the work process, even if the gloves are subjected to friction from external objects, the gloves will not fall off the worker's palm, reducing the possibility of injury to the worker and improving the safety of the heat-insulating gloves.

[0009] Optionally, the connecting component includes Velcro, the fleece surface of the Velcro is connected to the glove body, and the hook surface of the Velcro is connected to the other end of the tightening belt. When the tightening belt is connected, the fleece surface fits with the hook surface.

[0010] By adopting the above technical solution, the staff uses the cooperation of the hook surface and the fleece surface to connect the tightening belt to the glove body, thereby realizing the connection of the tightening belt, which is quick and convenient to operate and improves the wearing efficiency of the heat-insulating gloves.

[0011] Optionally, the connecting assembly includes connecting teeth, a connecting plate, a limiting frame, a limiting column and a toggle rod, the connecting plate is connected to the other end of the tightening belt, several connecting teeth are connected to one side of the connecting plate, the limiting frame is connected to the glove body, a connecting block is connected to the limiting frame, the connecting block and the connecting teeth are both made of deformable material, the limiting column is connected to the connecting block, one end of the toggle rod is connected to the limiting column, the limiting frame has an avoidance groove at the position corresponding to the toggle rod, the other end of the toggle rod passes through the avoidance groove, and when the tightening belt is connected, the connecting plate passes through the limiting frame, and the limiting column abuts between two adjacent connecting teeth.

[0012] By adopting the above technical solution, when tightening the heat-insulating gloves, the staff passes the tightening belt through the limiting frame. During this process, the connecting teeth abut against the limiting column, and the connecting teeth are deformed, so that the limiting column passes through a number of connecting teeth until the tightening notch is tightened to fit the palm of the staff. At this time, the connecting teeth abut against the limiting column; when loosening the tightening belt, the staff moves the toggle rod to deform the connecting block, so that the limiting column moves until it is separated from the connecting teeth, thereby taking out the tightening belt, thereby realizing the loading and unloading of the heat-insulating gloves.

[0013] Optionally, a hand-tear notch is provided on the glove body, a hand-tear tape is connected to the hand-tear notch, the hand-tear tape covers the hand-tear notch, and a limiting component for limiting the hand-tear tape is provided on the glove body.

[0014] By adopting the above technical solution, it is inevitable that the heat-insulating gloves of the staff will be restrained by the mobile equipment during work, resulting in the phenomenon that the gloves cannot be removed from the palm in a short time. At this time, if the heat-insulating gloves are not removed in a way, the staff may be injured. When removing the heat-insulating gloves in an emergency, the staff pulls the hand-tear belt to loosen the limiting component. At this time, the staff can remove the palm from the heat-insulating gloves, achieving the effect of emergency removal of the heat-insulating gloves. At the same time, during the work process, the glove body will deform after contacting an object, so that a gap will be generated between the hand-tear belt and the glove body, and external air can enter the gloves, reducing the possibility of moisture inside the heat-insulating gloves due to the airtightness of the heat-insulating gloves.

[0015] Optionally, the limiting component includes a limiting block, a fixing block and a limiting flange, the limiting block is connected to two blocks on the glove body, the fixing block is connected to the hand-tear tape, two mounting grooves are provided on the fixing block, the limiting flange is connected to the side wall of the mounting groove, the limiting flange is made of deformable material, the limiting block is provided with a limiting groove matching the shape of the limiting flange, and when limiting the hand-tear tape, the limiting block is located in the mounting groove, and the limiting flange is embedded in the limiting groove.

[0016] By adopting the above technical solution, when installing the hand-tear tape, the staff moves the fixed block into the installation groove. During this process, the limiting flange contacts the limiting block and deforms until the limiting flange is embedded in the limiting groove and the limiting flange is restored, thereby limiting the movement of the hand-tear tape and realizing the installation of the hand-tear tape.

[0017] Optionally, the glove body includes a heat-resistant outer layer, a thermal insulation layer and a skin-contacting inner layer, the thermal insulation layer is connected between the heat-resistant outer layer and the skin-contacting inner layer, the heat-resistant outer layer is used to protect the thermal insulation layer for a short time, the thermal insulation layer is used to block heat from being transferred to the skin-contacting inner layer for a short time, and the skin-contacting inner layer is used to improve the internal comfort of the heat-insulating gloves.

[0018] By adopting the above technical solution, the staff uses the heat-resistant outer layer to protect the thermal insulation layer to reduce the possibility of wear of the thermal insulation layer, and then uses the thermal insulation layer to temporarily isolate the heat, so that the staff has sufficient time to remove the thermal insulation gloves from the heat source. Finally, the skin-friendly inner layer is used to further isolate the heat from penetrating, while helping to improve the comfort inside the thermal insulation gloves, thereby improving the applicability of the thermal insulation gloves.

[0019] Optionally, the heat-resistant outer layer is made of aluminum-plated aramid composite fabric, the aluminum plating thickness in the heat-resistant outer layer is 1um-20um, the aramid fabric is a woven fabric, the aramid content is 50%-90%, and the antistatic silk content is 2%-5%.

[0020] By adopting the above technical scheme, the aluminized aramid composite fabric has the properties of high temperature resistance, wear resistance, high strength, light weight and corrosion resistance, which makes the thermal insulation gloves more durable, reduces the possibility of damage to the thermal insulation gloves, and extends the service life of the thermal insulation gloves.

[0021] Optionally, the thermal insulation layer is made of flame-retardant ceramic fiber felt fabric, the thermal insulation layer has a withstand temperature of 1000° C.-1500° C., and a fiber diameter of 100nm-5000nm.

[0023] Optionally, the skin-contacting inner layer is made of flame-retardant viscose fiber and aramid plain knitted fabric, the yarn count of the skin-contacting inner layer is 10-20 count, and the weight is 150g-300g.

[0024] By adopting the above technical scheme, the flame retardant viscose fiber has the characteristics of high strength, high toughness, water absorption, environmental protection, antibacterial and flame retardancy, which further blocks the further penetration of heat, improves the comfort of the thermal insulation gloves, and improves the applicability of the thermal insulation gloves.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. When putting on the glove body, the worker puts his palm into the glove body, then passes the tightening belt through the connection closed loop until the tightening notch is tightened to fit the palm, and finally uses the connection component to connect the tightening belt to the glove body to put on the glove body. The worker uses the tightening belt and the connection closed loop to adjust the tightening notch so that the gloves can adapt to the sizes of different workers' hands. Even if the gloves are subject to friction from external objects during work, the gloves will not fall off the worker's palm, reducing the possibility of injury to the worker and improving the safety of the heat-insulating gloves;

[0027] 2. When tightening the heat-insulating gloves, the staff passes the tightening belt through the limiting frame. During this process, the connecting teeth abut against the limiting column, and the connecting teeth are deformed, so that the limiting column passes through a number of connecting teeth until the tightening notch is tightened to fit the palm of the staff. At this time, the connecting teeth abut against the limiting column; when loosening the tightening belt, the staff moves the toggle rod to deform the connecting block, so that the limiting column moves until it is separated from the connecting teeth, thereby taking out the tightening belt, and realizing the loading and unloading of the heat-insulating gloves;

[0047] The staff uses the heat-resistant outer layer 11 to increase the durability of the thermal insulation gloves and reduce the possibility of wear of the thermal insulation gloves, and then uses the thermal insulation layer 12 to temporarily block heat from penetrating into the thermal insulation gloves. Finally, the skin-contacting inner layer 13 is used to further block heat while improving the comfort of the thermal insulation gloves, thereby improving the applicability of the thermal insulation gloves.

[0048] Reference Figure 1The entrance end of the glove body 1 is provided with a tightening notch 14, and a tightening assembly 2 is arranged at the tightening notch 14, and the tightening assembly 2 includes a tightening belt 21 and a connecting closed loop 22. The connecting closed loop 22 is hinged on one side of the tightening notch 14, one end of the tightening belt 21 is fixedly connected to the other side of the tightening notch 14, and the other end of the tightening belt 21 passes through the connecting closed loop 22.

[0049] Reference Figure 1 A connecting component 3 is provided between the tightening belt 21 and the glove body 1, and the connecting component 3 includes a Velcro 31. The hook surface of the Velcro 31 is fixedly connected to the other end of the tightening belt 21, and the fur surface of the Velcro 31 is fixedly connected to the glove body 1, and the hook surface fits the fur surface.

[0050] When wearing the heat-insulating gloves, the worker puts the glove body 1 on the palm, then passes the other end of the tightening belt 21 through the connecting closed loop 22, until the tightening notch 14 is tightened until the glove body 1 fits the palm, and finally fits the hook surface to the fleece surface, thus achieving the wearing of the heat-insulating gloves.

[0051] Reference Figure 3 and Figure 4 The glove body 1 is also provided with a hand-tear notch 15, and a hand-tear tape 16 is fixedly connected to the inner bottom wall of the hand-tear notch 15, and the hand-tear tape 16 covers the hand-tear notch 15. A limiting component 4 is arranged between the hand-tear tape 16 and the glove body 1, and the limiting component 4 includes a limiting block 41, a fixed block 42 and a limiting flange 43. Two limiting blocks 41 are fixedly connected on the glove body 1, and the hand-tear tape 16 is located between the two limiting blocks 41. The fixed block 42 is fixedly connected to the hand-tear tape 16, and two mounting grooves 421 are formed on the fixed block 42. The limiting flange 43 is fixedly connected to a side wall of the mounting groove 421, and the limiting flange 43 is made of a deformable material, such as plastic. The limiting block 41 is located in the mounting groove 421, and a limiting groove is formed on the limiting block 41, and the limiting flange 43 is embedded in the limiting groove.

[0052] When the glove body 1 is removed urgently, the worker pulls the tear tape 16 to move and deform the limiting flange 43 , so that the limiting block 41 is separated from the mounting groove 421 , and the limiting flange 43 is separated from the limiting groove, so that the palm can be removed from the glove body 1 .

[0053] The implementation principle of a heat-insulating glove in Example 1 of the present application is as follows: when wearing the heat-insulating gloves, the staff puts the glove body 1 on the palm, then passes the tightening belt 21 through the connecting closed loop 22 until the tightening notch 14 is adjusted to fit the palm, and finally fits the hook surface to the fleece surface to achieve the installation of the heat-insulating gloves.

[0054] When removing the gloves urgently, the staff pulls the fixing block 42 to move the tearing belt 16. During this process, the limiting flange 43 is deformed until the limiting flange 43 is separated from the limiting groove and restored, and the staff can take out the palm.

[0055] The staff utilizes the tightening belt 21 and the connecting closed loop 22 to adjust the tightening notch 14 so that the gloves can adapt to the sizes of hands of different staff members. Even if the gloves are subjected to friction from external objects during work, the gloves will not fall off the palms of the staff members, thereby reducing the possibility of injury to the staff members and improving the safety of the heat-insulating gloves.

[0056] Embodiment 2: The difference between this embodiment and embodiment 1 is that the structure of the connecting component 3 is different.

One end of the toggle rod 36 is fixedly connected to the limiting column 35, and a avoidance groove is opened at the position of the limiting frame 34 corresponding to the toggle rod 36, and the other end of the toggle rod 36 passes through the avoidance groove. The connecting plate 33 is fixedly connected to the tightening belt 21, and a plurality of connecting teeth 32 are fixedly connected on one side of the connecting plate 33, and the connecting teeth 32 are made of a deformable material, such as plastic. When the tightening belt 21 is connected, the limiting column 35 abuts between two adjacent connecting teeth 32.

[0058] When connecting the tightening band 21, the staff passes the connecting plate 33 through the limiting frame 34. During this process, the connecting teeth 32 abut against the limiting column 35 and are deformed until the tightening notch 14 is adjusted to fit the staff's palm. At this time, two of the connecting teeth 32 abut against the limiting column 35 to limit the movement of the tightening band 21; when loosening the tightening band 21, the staff moves the toggle rod 36 to move the limiting column 35, and the connecting block 351 is deformed to cause the limiting column 35 to disengage from the connecting teeth 32, so that the tightening band 21 can be pulled out of the limiting frame 34, thereby realizing the installation of the tightening band 21.

[0059] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
