DESCRIPTION OF THE EMBODIMENTS

[0041] This application is described in detail below in combination with embodiments.

Embodiment 1

[0042] A highly soft and anti-shock labor protection glove, as shown in FIG. 1 and FIG. 2, includes a glove body 1. A wear-resistant rubber layer 6 is disposed at one side of a palm of the glove body 1 by dipping. The glove body 1 includes a glove liner 2 and a back rubber protection layer 3 disposed on a surface of a back of the glove liner 2. The glove liner 2 includes a skin contact layer 21 woven by at least one of cotton, spandex, polyester and aramid, a moisture absorption layer 22 sewn outside the skin contact layer 21 and woven by a blend of cotton, spandex and bamboo charcoal fiber, and a wear-resistant layer 23 sewn outside the moisture absorption layer 22 and woven by at least one of polyester, nylon and aramid.

[0043] As shown in FIG. 1, FIG. 3 and FIG. 4, the back rubber protection layer 3 includes a finger rubber layer 31 disposed at a back of fingers of the glove, and a plurality of grooves 311 are disposed at a surface of the finger rubber layer 31 for increasing flexibility of the finger rubber layer 31 when stretching out or bending inward with knuckles. A palm-back rubber layer 32 is injection molded at a back of the palm of the glove body 1 for providing effective shock-proof protection for the back of the palm. A surface of the palm-back rubber layer 32 is provided with a second division groove 321 including a plurality of transversal division grooves 3211 and longitudinal division grooves 3212 which cross each other to form a divided planar mesh structure, such that the palm-back rubber layer 32 can better conform a back of the hand when it deforms with the back of the hand, thereby improving the adaptability of the palm-back rubber layer 32 and the comfort for wearing.

[0044] As shown in FIG. 1 and FIG. 4, a root knuckle rubber layer 33 for protecting root knuckles is disposed between the finger rubber layer 31 and the palm-back rubber layer 32 by injection molding. A plurality of arc-shaped recesses 331 are disposed at one side of the root knuckle rubber layer 33 close to the finger rubber layer 31 with openings of all the arc-shaped recesses 331 facing the finger rubber layer 31. When the palm and fingers bend inward to perform gripping operation, the root knuckles will bend and protrude toward the outside of the back of a hand so that the arc-shaped recesses 331 disposed at one side of the root knuckle rubber layer 33 close to the finger rubber layer 31 are deformed corresponding to the bending of the root knuckles. In addition, the openings of the arc-shaped recesses 331 face the finger rubber layer 31, so that the root knuckle rubber layer 33 better conform the knuckles during movement, which further improves the flexibility and shock-proof effect of the root knuckle rubber layer 33.

[0045] As shown in FIG. 1 and FIG. 4, a connection rubber layer 4 is disposed at one side of the root knuckle rubber layer away from the finger rubber layer 31, and the connection rubber layer 4 is integrally connected with the root knuckle rubber layer 33 and the palm-back rubber layer 32 by injection molding, respectively. A first division groove 332 is disposed at one side of the arc-shaped recesses 331 of the root knuckle rubber layer 33 close to the palm-back rubber layer 32. A pair of groove-shaped openings 5 symmetrical with respect to the connection rubber layer 4 are disposed between the root knuckle rubber layer 33 and the palm-back rubber layer 32 for increasing flexibility of the root knuckle rubber layer 33 and flexibility of the palm-back rubber layer 32 for moving with the movement of joints of a hand.

Embodiment 2

[0046] A production method of a labor protection glove includes the following steps.

[0047] Step 1, preparing the glove liner 2: weaving the skin contact layer 21 and the moisture absorption layer 22 to form the glove liner 2.

[0048] Step 2, sewing the wear-resistant layer 23: sewing the wear-resistant layer 23 on an outer surface of the glove liner 2.

[0049] Step 3, preparing the back rubber protection layer 3: wearing the glove liner 2 on a hand model, placing the hand model with the glove liner 2 into a rubber-injecting mould of an integrated injection molding machine, closing the rubber-injecting mould, injecting rubber into rubber-injecting holes located above the fingers of the glove while injecting molten rubber into rubber-injecting holes located at root knuckles, and cooling to integrally forming the root knuckle rubber layer 33 and the palm-back rubber layer 32, so as to provide the back rubber protection layer 3 via rubber injection, wherein a rubber-injecting temperature is in a range of 180-220 C., a rubber-injecting pressure is in a range of 15-22 MPa, and the molten rubber in the step 3 is one selected from a group consisting of thermoplastic elastomer (TPE), thermoplastic rubber (TPR) and thermoplastic polyurethane (TPU).

[0050] Working principle is as follows. The molten rubber is injected into the interior of the mould through the rubber-injecting hole located on the rubber-injecting mould of the integrated injection molding machine, so as to form the back rubber protection layer 3, which greatly improves the production efficiency and the processing quality of the back rubber protection layer 3. At the same time, the rubber is injected into the upper surface of the fingers of the glove from individual rubber-injecting holes located above the fingers, so as to independently form the finger rubber layer 31 by rubber injection. That is, the root knuckle rubber layer 33 and the palm-back rubber layer 32 can be formed for one time by injecting rubber into the rubber-injecting holes at the root knuckles of fingers of the glove. Such rubber injection from independent rubber-injecting holes can not only improve the rubber-injecting efficiency and rubber-injecting accuracy, but also effectively improve the utilization rate of the rubber, which significantly reduces the waste of the rubber thereby reducing the production cost.

[0051] What is provided above is merely some preferred embodiments of this application. The scope of this application is not limited by the above embodiments, but should include all technical solutions under the thinking of this application. It is to be noted that, some improvements and modifications can be made by those skilled in the art without departing from the principle of this application, and should be considered to fall within the scope of this application.
