The two ends of the main body are usually fixed by using magic tape, that is, one end of the main body is provided with a magic hook surface, and the other end is provided with a magic hair surface. The magic hook surface and the magic hair surface are pasted to realize the fixation of the protective equipment. Since the unit area connection force of the magic tape is small, in order to obtain a larger connection force, the magic tape needs to occupy a larger area on the main body. The magic tape covers the air holes at the connection of the main body, and the large occupied area of the magic tape leads to poor air permeability of the protective equipment at the connection.

[0058] The band body 10 can refer to the body of the band 100, among the two ends of the band body 10 distributed along the length direction, one end is the first end 101, and the other end is the second end 102; when the band body 10 is wound outside the body, the first end 101 and the second end 102 are fixed, so as to fix the body on the part to be protected.
[0059] The shape of the band body 10 can be matched with the shape of the part to be protected, so as to better wrap outside the part to be protected; for example, the band body 10 can be in the shape of a long strip; the band body 10 can have a certain elasticity, so as to facilitate the fixation of the band body 10; the material of the band body 10 can be rubber, elastic cloth and the like; the band body 10 can be an integral structure, that is, the band body 10 is made of one piece of material, or can be spliced by multiple pieces of material, the materials of the adjacent two pieces of material can be the same or different; in addition, the material can be a single-layer material or a multi-layer material; the band body 10 can be provided with a supporting strip and the like, so as to better support the part to be protected.
[0060] The first end 101 is provided with a hooking hole 103, which is a through hole penetrating the band 10 along the thickness direction of the band 10. The hooking member 20 penetrates the hooking hole 103, so that the hooking member 20 penetrates the band 10, and the hooking and fixing of the bandage 100 are realized.

[0065] For example, the second end 102 of the band 10 penetrates the fixing part 21, and the band 10 is integrally injection molded with the fixing part 21.
[0066] The fixing part 21 can also be separately formed with the band 10 and then assembled together.
[0067] For example, the fixing part 21 and the band 10 can be sewn together, and the fixing part 21 can also be sleeved and fixed to the second end 102 of the band 10.
[0068] The hooking part 22 can be a part of the hooking member 20 for hooking with the hooking hole 103. One end of the hooking part 22 is connected to the surface of the fixing part 21 along the thickness direction of the band 10, that is, one of the two surfaces of the fixing part 21 relatively distributed along the thickness direction of the band 10 is connected with the hooking part 22, and the hooking part 22 protrudes from the surface. In this way, after the band 10 is wound around, the second end 102 overlaps with the first end 101, the hooking part 22 can be hooked in the hooking hole 103 of the first end 101, and the binding of the bandage 100 is realized.
[0069] The hooking part 22 can be an arc-shaped strip structure, and the shape of the hooking part 22 can be similar to a quarter of a circle or a hook, etc.
[0070] The hooking part 22 and the fixing part 21 can be integrally formed, or separately formed and then assembled together.

[0072] In the unfolded state of the belt body 10, a first virtual plane M and a second virtual plane N are taken, the first virtual plane M and the second virtual plane N are both perpendicular to the thickness direction of the belt body 10, the first virtual plane M and the second virtual plane N are arranged in parallel and spaced apart, the first virtual plane M and the second virtual plane N both intersect the hooking part 22, the first virtual plane M divides the hooking part 22 into two parts, one part away from the fixing part 21 is a first threading segment 221, and the other part close to the fixing part 21 is a connecting segment 222, the connecting segment 222 is located between the first virtual plane M and the fixing part 21, the hooking part 22 is located on the side of the first virtual plane M away from the fixing part 21, and the first threading segment 221 is connected between the first threading segment 221 and the fixing part 21.
[0073] The second virtual plane N is located between the first virtual plane M and the fixing part 21, the distance S1 between the first virtual plane M and the second virtual plane N is equal to the hole depth H of the hooking hole 103, the distance between the first virtual plane M and the fixing part 21 is equal to the hole depth H of the hooking hole 103; or, the distance between the first virtual plane M and the fixing part 21 is greater than the hole depth H of the hooking hole 103.
[0074] In some examples, the belt body 10 is of an equal thickness structure, the hole depth H of the hooking hole 103 is equal to the thickness of the belt body 10.
[0075] In some examples, the belt body 10 is of an unequal thickness structure, the hole depth H of the hooking hole 103 is equal to the thickness of the belt body 10 at the hooking hole 103.
[0076] The second virtual plane N divides the hooking part 20 into two parts, one part away from the fixing part 21 is a hook body 2201, and the hook body 2201 includes the part of the first threading segment 221 and the connecting segment 222 located between the first virtual plane M and the second virtual plane N.
[0077] In some examples, the entire connecting segment 222 is located between the first virtual plane M and the second virtual plane N, the height of the connecting segment 222 is equal to the hole depth H of the hooking hole 103, and the first threading segment 221 and the connecting segment 222 jointly constitute the hook body 2201.
[0078] In some examples, a portion of the connecting segment 222 is located between the first virtual plane M and the second virtual plane N, the height of the connecting segment 222 is greater than the hole depth H of the hooking hole 103, and the first penetrating segment 221 and the portion of the connecting segment 222 located between the second virtual plane N and the fixing portion 21 collectively constitute the hook body 2201.
[0079] Any third virtual plane O and fourth virtual plane P are located on the hook body 2201, the third virtual plane O and the fourth virtual plane P are parallel to the first virtual plane M, and the distance S2 between the third virtual plane O and the fourth virtual plane P is equal to the hole depth H of the hooking hole 103, so that the third virtual plane O and the fourth virtual plane P can simulate the process of hooking the hooking member 20 to the hooking hole 103.
[0080] The radial direction of the hooking hole 103 can refer to the direction perpendicular to the hole depth H of the hooking hole 103.
[0081] For example, the radial direction of the hooking hole 103 can refer to the X direction in the drawings.
[0082] The first virtual plane M, the second virtual plane N, the third virtual plane O, and the fourth virtual plane P are virtual planes, and the hooking portion 22 can have no obvious structural identification or can have obvious structural identification, such as recesses, protrusions, and other identification structures.
[0083] In some technologies, the hooking portion 22 is a curved structure to reduce the risk of the hooking portion 22 being pulled out of the hooking hole 103, but in the process of hooking the hooking portion 22 to the hooking hole 103, the hooking hole 103 is sleeved on one end of the hooking portion 22, and then the hooking hole 103 is manually adjusted to be flipped along the curved direction of the hooking portion 22, so as to realize the hooking connection of the hooking hole 103 and the hooking portion 22. This connection mode is complicated to operate.
[0084] In the embodiment of the present application, along the radial direction of the hooking hole 103, the size L1 of the part of the hook body 2201 between the third virtual plane O and the fourth virtual plane P is less than or equal to the size D of the hooking hole 103, so that during the overlapping connection of the first end 101 and the second end 102, the first end 101 can be directly translated towards the second end 102, so that the first penetrating segment 221 can directly penetrate through the hooking hole 103, without the need for manual adjustment of the rotation of the hooking hole 103 along the bending direction of the hooking portion 22, thereby realizing the hooking of the hooking member 20 and the hooking hole 103, simplifying the connection and fixing operation of the bandage 100, and improving the convenience of the fixing of the bandage 100; and during this process, the hooking hole 103 can be moved to the side of the first virtual plane M towards the fixing portion 21, the first penetrating segment 221 can completely penetrate through the hooking hole 103, and the hooking hole 103 is sleeved on the connecting segment 222, that is, the hooking member 20 can penetrate through the hooking hole 103 and expose a part outside, which is beneficial to improve the hooking stability of the hooking member 20 and the hooking hole 103.
[0085] The bandage 100 of the embodiment of the present application, when in use, after the body is wound outside the part to be protected, the belt body 10 is wound outside the body, then the first end 101 and the second end 102 are overlapped, and then the hooking hole 103 at the first end 101 of the belt body 10 is slightly moved to the hooking member 20 at the second end 102 of the belt body 10 under force, so that the belt body 10 generates a certain tension; then, the first end 101 can be directly translated towards the second end 102, so that the hooking hole 103 is directly sleeved on the hook body 2201; finally, the first end 101 and the second end 102 are loosened, and under the tension of the belt body 10, the outer peripheral wall of the hook body 2201 abuts against the inner wall of the hooking hole 103, thereby realizing the hooking and fixing of the hooking member 20 and the hooking hole 103. It should be noted that, in order to facilitate the illustration, Figures 4-6 In the embodiment, the hooking hole 103 is represented by a hole formed by a circular ring.
[0086] The bandage 100 of the embodiment of the present application adopts the hooking mode of the hooking member 20 and the hooking hole 103, compared with the mode of using magic tape, the connection reliability of the hooking member 20 and the hooking hole 103 is good, the occupied area of the hooking member 20 and the hooking hole 103 at the connection of the protector can be reduced, which is beneficial to improve the air permeability of the protector at the connection, and improve the air permeability of the protector; in addition, during the overlapping connection of the first end 101 and the second end 102, the first end 101 can be directly moved towards the second end 102, the hook body 2201 can directly penetrate through the hooking hole 103, the hooking of the hooking member 20 and the hooking hole 103 is realized, and the connection and fixing operation of the bandage 100 is simple and convenient.
[0087] In some embodiments, the hooking portion 22 and the hooking hole 103 are gap-fitted.
[0088] When the hooking portion 22 is hooked in the hooking hole 103, a gap exists between the hooking portion 22 and the hole wall of the hooking hole 103, which allows gas to pass through, thereby improving the air permeability of the protector; in addition, the hooking portion 22 is also easy to be hooked in the hooking hole 103, thereby facilitating the connection of the bandage 100.
[0089] In some embodiments, the belt body 10 is provided with air permeation holes 104, which can be distributed on the entire belt body 10 or on a partial area of the belt body 10, and the specific distribution can be set according to actual needs. The air permeation holes 104 can also be used as the hooking holes 103, which is beneficial to improve the adjustment range of the binding size of the belt body 10 and improve the application range of the protector.
[0090] In some embodiments, the number of the hooking holes 103 is multiple, and the multiple hooking holes 103 form multiple columns of hooking holes 103. Each column of hooking holes 103 includes one or more hooking holes 103, and the multiple columns of hooking holes 103 are arranged along the length direction of the belt body 10.
[0091] For example, the number of the hooking holes 103 is multiple, and the multiple hooking holes 103 can be arranged in a matrix. The hooking holes 103 arranged along the width direction of the belt body 10 form a column of hooking holes 103, and the multiple columns of hooking holes 103 are arranged along the length direction of the belt body 10. Each column of hooking holes 103 includes multiple hooking holes 103, and the multiple hooking holes 103 in the same column of hooking holes 103 are arranged along the width direction of the belt body 10. Of course, each column of hooking holes 103 can also include one hooking hole 103, and the multiple hooking holes 103 are arranged along the length direction of the belt body 10.
[0092] By adopting the technical scheme of this embodiment, the hooking portion 22 is hooked in the hooking holes 103 in different columns, thereby meeting different binding size requirements and improving the application range of the protector. In addition, the hooking holes 103 that are not hooked with the hooking portion 22 can also be used as the air permeation holes 104, which is beneficial to improve the air permeability of the protector.
[0093] In some embodiments, the belt body 10 is a honeycomb belt body, and the belt body 10 is provided with honeycomb holes arranged in a honeycomb pattern. The honeycomb holes cover the entire belt body 10, and the honeycomb holes can be used as the air permeation holes 104 or the hooking holes 103. In this way, the air permeability of the belt body 10 can be effectively improved, and the adjustment range of the binding size of the belt body 10 is wider. In addition, the structure of the belt body 10 is simple, and the belt body 10 is also easy to process and manufacture.
[0094] In some embodiments, the number of the hooking portions 22 is multiple, and the multiple hooking portions 22 can be hooked with multiple hooking holes 103 in at least one column of hooking holes 103.
[0095] As an example, the plurality of hooking portions 22 can be arranged to form a column, and the column of hooking portions 22 can be hooked with the plurality of hooking holes 103 in the corresponding column; wherein one hooking portion 22 can be hooked with one hooking hole 103, or a plurality of hooking portions 22 can be hooked with one hooking hole 103.
[0096] As an example, the plurality of hooking portions 22 can also be arranged to form a plurality of columns, and the plurality of columns of hooking portions 22 can also be hooked with the plurality of columns of hooking holes 103.
[0097] By adopting the technical solutions of this embodiment, the design of the plurality of hooking portions 22 can realize the hooking of the hooking member 20 with the plurality of hooking holes 103, realize multi-point hooking, be beneficial to improving the connection reliability of the first end 101 and the second end 102, be beneficial to improving the binding stability of the binding belt 100, and improve the protection effect of the protective gear.
[0098] In some embodiments, in the unfolded state of the belt body 10, the hooking portion 22 protrudes from the fixing portion 21 and extends obliquely or curvedly towards the first end 101; the point in the end face of the hooking portion 22 farthest from the fixing portion 21 is the terminal point, and the terminal point is located on the first virtual plane M.
[0099] In the unfolded state of the belt body 10, the farther the hooking portion 22 is from the fixing portion 21, the closer it is to the first end 101, and the distance between the end of the hooking portion 22 close to the fixing portion 21 and the first end 101 is greater than the distance between the end of the hooking portion 22 far from the fixing portion 21 and the first end 101.
[0100] As an example, the hooking portion 22 extends linearly obliquely towards the first end 101 relative to the fixing portion 21, that is, the hooking portion 22 can be linear.
[0101] As an example, the hooking portion 22 extends curvedly towards the first end 101 relative to the fixing portion 21, and the hooking portion 22 is arc-shaped.
[0102] The point in the end face of the hooking portion 22 farthest from the fixing portion 21 is the terminal point, and the first virtual plane M passes through the terminal point.
[0103] As an example, the end face of the hooking portion 22 farthest from the fixing portion 21 can be a plane, and the point in the plane closest to the fixing portion 21 is the terminal point.
[0104] As an example, the periphery of the end face of the hooking portion 22 farthest from the fixing portion 21 can be provided as a circular arc face, and the point on the circular arc face closest to the fixing portion 21 is the terminal point.
[0105] By adopting the technical scheme of the embodiment, after the hooking portion 22 is inserted into the hooking hole 103, the end of the hooking portion 22 away from the fixing portion 21 can block the hooking portion 22 from being pulled out of the hooking hole 103, thereby improving the stability of the hooking of the hooking member 20 in the hooking hole 103, and improving the stability of the fixing of the protective gear and the protection effect of the protective gear.
[0106] In some embodiments, the hooking portion 22 is an arc-shaped portion protruding away from the fixing portion 21.
[0107] Under the tension of the belt body 10, the hooking portion 22 can provide a force to the hooking hole 103 to move towards the fixing portion 21, so that the hooking hole 103 can move towards the fixing portion 21 along the hooking portion 22, and the hooking portion 22 can automatically further enter the hooking hole 103, thereby making the hooking operation of the hooking portion 22 and the hooking hole 103 simpler, and reducing the risk of the hooking portion 22 being pulled out of the hooking hole 103.
[0108] In some embodiments, referring to Figures 7-9 As shown in the figure, the first penetrating segment 221 includes a first sub-segment 2211 and a second sub-segment 2212. When the belt body 10 is in the unfolded state, the first sub-segment 2211 extends or bends away from the fixing portion 21 and towards the first end 101 from the end of the connecting segment 222 away from the fixing portion 21, and the second sub-segment 2212 extends or bends away from the fixing portion 21 and towards the first end 101 from the end of the first sub-segment 2211 away from the fixing portion 21.
[0109] When the belt body 10 is in the unfolded state, the second sub-segment 2212 is located on the side of the first sub-segment 2211 away from the first end 101, one end of the first sub-segment 2211 is connected to the connecting segment 222, and the other end of the first sub-segment 2211 is connected to one end of the second sub-segment 2212. The farther the first sub-segment 2211 is from the fixing portion 21, the closer it is to the first end 101, and the closer the second sub-segment 2212 is to the fixing portion 21, the closer it is to the first end 101, so that the connecting segment 222, the first sub-segment 2211, and the second sub-segment 2212 form an inverted “hook” shape or a structure similar to an inverted “hook” shape.
[0110] When the belt body 10 is in the unfolded state, the distance between the end of the first sub-segment 2211 close to the fixing portion 21 and the first end 101 is greater than the distance between the end of the first sub-segment 2211 away from the fixing portion 21 and the first end 101, and the distance between the end of the second sub-segment 2212 close to the fixing portion 21 and the first end 101 is less than the distance between the end of the second sub-segment 2212 away from the fixing portion 21 and the first end 101.
[0111] For example, the first sub-segment 2211 extends linearly towards the first end 101 relative to the fixing portion 21, that is, the first sub-segment 2211 is linear.
[0112] For example, the first sub-section 2211 extends curvedly towards the first end 101 relative to the fixed section 21, and the first sub-section 2211 is arc-shaped.
[0113] For example, the second sub-section 2212 extends linearly inclinedly relative to the first sub-section 2211, and the second sub-section 2212 is linear.
[0114] For example, the second sub-section 2212 extends curvedly towards the first end 101 relative to the first sub-section 2211, and the second sub-section 2212 is arc-shaped.
[0115] The first sub-section 2211 and the second sub-section 2212 can be integrally formed, or can be separately formed and then connected together.
[0116] For example, in the unfolded state of the band 10, the projection of the first sub-section 2211 coincides with the projection of the second sub-section 2212 in the length direction of the band 10, and the second sub-section 2212 is spaced apart from the fixed section 21 in the thickness direction of the band 10. After the first sub-section 2211 and the second sub-section 2212 pass through the hooking hole 103, the connecting section 222 can be hooked in the hooking hole 103, so that the first passing section 221 can completely pass through the hooking hole 103.
[0117] By adopting the technical scheme of this embodiment, the connecting section 222, the first sub-section 2211 and the second sub-section 2212 form a structure of one or similar to an inverted “hook” shape. After the hooking section 22 is hooked in the hooking hole 103, the hooking hole 103 needs to be turned along the first sub-section 2211 and the second sub-section 2212 to make the hooking section 22 exit the hooking hole 103, which increases the difficulty of the hooking section 22 exiting the hooking hole 103, and improves the stability and reliability of the hooking of the hooking section 22 and the hooking hole 103.
[0118] In some embodiments, referring to Figures 10-12 As shown in the figure, the first passing section 221 further includes a third sub-section 2213. In the unfolded state of the band 10, the third sub-section 2213 extends inclinedly or curvedly away from the first sub-section 2211 towards the fixed section 21 and away from the first end 101.
[0119] In the unfolded state of the band 10, the third sub-section 2213 is located between the second sub-section 2212 and the fixed section 21, one end of the first sub-section 2211 is connected with the connecting section 222, the other end of the first sub-section 2211 is connected with one end of the second sub-section 2212, the other end of the second sub-section 2212 is connected with one end of the third sub-section 2213, the third sub-section 2213 is closer to the first end 101 as it is farther away from the fixed section 21, and the connecting section 222, the first sub-section 2211, the second sub-section 2212 and the third sub-section 2213 form an inverted "hook" shape or a structure similar to the inverted "hook" shape.
[0120] In the unfolded state of the band 10, the distance between the end of the third sub-section 2213 close to the fixed section 21 and the first end 101 is greater than the distance between the end of the third sub-section 2213 away from the fixed section 21 and the first end 101.
[0121] For example, the third sub-section 2213 extends linearly relative to the second sub-section 2212, that is, the third sub-section 2213 is linear.
[0122] For example, the third sub-section 2213 extends curvedly relative to the second sub-section 2212 towards the first end 101, and the third sub-section 2213 is arc-shaped.
[0123] The third sub-section 2213 and the second sub-section 2212 can be integrally formed or separately formed and then connected together.
[0124] For example, in the unfolded state of the band 10, the projection of the second sub-section 2212 and the third sub-section 2213 coincides with the projection of the first sub-section 2211 in the length direction of the band 10, and the third sub-section 2213 is spaced apart from the fixed section 21 in the thickness direction of the band 10, and after the third sub-section 2213 passes through the hooking hole 103, the connecting section 222 can be hooked in the hooking hole 103, so that the first passing section 221 can completely pass through the hooking hole 103.
[0125] By adopting the technical scheme of this embodiment, the connecting section 222, the first sub-section 2211, the second sub-section 2212 and the third sub-section 2213 form an inverted "hook" shape or a structure similar to the inverted "hook" shape, and it is difficult for the hooking section 22 to come out of the hooking hole 103, thereby improving the stability and reliability of the hooking between the hooking section 22 and the hooking hole 103.
[0126] In some embodiments, referring to Figure 13 As shown in the figure, the first passing section 221 further includes a fourth sub-section 2214, and in the unfolded state of the band 10, the fourth sub-section 2214 extends linearly or curvedly away from the fixed section 21 and away from the first end 101 from the end of the third sub-section 2213 away from the second sub-section 2212.
[0127] In the unfolded state of the band 10, the fourth sub-section 2214 is located between the third sub-section 2213 and the first sub-section 2211, one end of the first sub-section 2211 is connected with the connecting section 222, the other end of the first sub-section 2211 is connected with one end of the second sub-section 2212, the other end of the second sub-section 2212 is connected with one end of the third sub-section 2213, the other end of the third sub-section 2213 is connected with one end of the fourth sub-section 2214, the closer the end of the fourth sub-section 2214 to the fixed part 21 is, the closer the end of the fourth sub-section 2214 to the first end 101 is, and the first sub-section 2211, the second sub-section 2212, the third sub-section 2213 and the fourth sub-section 2214 form a ring structure with a gap.
[0128] In the unfolded state of the band 10, the distance between the end of the fourth sub-section 2214 close to the fixed part 21 and the first end 101 is less than the distance between the end of the fourth sub-section 2214 away from the fixed part 21 and the first end 101.
[0129] For example, the fourth sub-section 2214 extends linearly relative to the third sub-section 2213, that is, the fourth sub-section 2214 is linear.
[0130] For example, the fourth sub-section 2214 extends curvedly relative to the third sub-section 2213 towards the first end 101, and the fourth sub-section 2214 is arc-shaped.
[0131] The fourth sub-section 2214 and the third sub-section 2213 can be integrally formed or separately formed and then connected together.
[0132] For example, in the unfolded state of the band 10, the projection of the second sub-section 2212 and the third sub-section 2213 along the length direction of the band 10 coincides with the projection of the first sub-section 2211 and the fourth sub-section 2214, and the fourth sub-section 2214 is spaced apart from the fixed part 21 in the thickness direction of the band 10, after the third sub-section 2213 and the fourth sub-section 2214 pass through the hooking hole 103, the connecting section 222 can be hooked in the hooking hole 103, so that the first passing section 221 can completely pass through the hooking hole 103.
[0133] By adopting the technical scheme of the embodiment, the first sub-section 2211, the second sub-section 2212, the third sub-section 2213 and the fourth sub-section 2214 can form a ring structure with a gap, and the hooking part 22 is difficult to be pulled out of the hooking hole 103, thereby improving the stability and reliability of the hooking between the hooking part 22 and the hooking hole 103.
[0134] In some embodiments, along the thickness direction of the band 10, the point closest to the fixed part 21 of the part of the first passing section 221 other than the first sub-section 2211 is the end point, and the end point is located on the first virtual plane M.
[0135] In some examples, referring to Figures 7-9 As shown, the first threading section 221 includes a first sub-section 2211 and a second sub-section 2212, the first sub-section 2211 is connected to the end of the connecting section 222 away from the fixing portion 21 and extends away from the fixing portion 21, the first sub-section 2211 is connected to the end of the second sub-section 2212 away from the fixing portion 21 and extends toward the fixing portion 21, and both the first sub-section 2211 and the second sub-section 2212 extend toward the first end 101, the first threading section 221 formed by the first sub-section 2211 and the second sub-section 2212 has a large size in the length direction of the band 10, which increases the difficulty of the first threading section 221 passing through the hooking hole 103; in the thickness direction of the band 10, the point closest to the fixing portion 21 of the first threading section 221 except the first sub-section 2211 is the point closest to the fixing portion 21 of the second sub-section 2212, i.e., the point closest to the fixing portion 21 of the second sub-section 2212 is the terminal point, and the terminal point is located on the first virtual plane M, in addition, the hooking hole 103 can pass through the hooking portion 22 on the side of the first virtual plane M away from the fixing portion 21 by the way of translation, i.e., the first sub-section 2211 and the second sub-section 2212 can pass through the hooking hole 103 by the way of translation of the hooking hole 103, which reduces the risk of the hooking hole 103 being turned over along the first threading section 221 and improves the convenience of the hooking of the hooking portion 22 and the hooking hole 103.
[0136] For example, the boundary surface between the first sub-section 2211 and the connecting section 222 can refer to the first virtual plane M, and the boundary surface between the first sub-section 2211 and the second sub-section 2212 can refer to the straight line A.
[0137] In some examples, referring to Figures 10-12As shown, the first threading section 221 includes a first sub-section 2211, a second sub-section 2212, and a third sub-section 2213, and the first threading section 221 formed by the first sub-section 2211, the second sub-section 2212, and the third sub-section 2213 has a large size in the length direction of the band 10, thereby increasing the difficulty of the first threading section 221 passing through the hooking hole 103; since the third sub-section 2213 extends from the end of the second sub-section 2212 away from the first sub-section 2211 towards the fixed portion 21, in the thickness direction of the band 10, the third sub-section 2213 is closer to the fixed portion 21 than the second sub-section 2212, therefore, the point closest to the fixed portion 21 of the part of the first threading section 221 other than the first sub-section 2211 is the point closest to the fixed portion 21 of the third sub-section 2213, that is, the point closest to the fixed portion 21 of the third sub-section 2213 is the terminal point, and the terminal point is located on the first virtual plane M, and in addition, the hooking hole 103 can pass through the part of the hooking portion 22 located on the side of the first virtual plane M away from the fixed portion 21 by translation, that is, the hooking hole 103 can pass through the first sub-section 2211, the second sub-section 2212, and the third sub-section 2213 by translation, thereby reducing the risk of the hooking hole 103 being turned along the first threading section 221 and improving the convenience of the hooking of the hooking portion 22 and the hooking hole 103.
[0138] For example, the boundary surface of the second sub-section 2212 and the third sub-section 2213 can refer to the straight line B.
[0139] In some examples, the boundary surface of the second sub-section 2212 and the third sub-section 2213 can refer to the straight line B. Figure 13 As shown, the first threading section 221 includes a first sub-section 2211, a second sub-section 2212, a third sub-section 2213, and a fourth sub-section 2214, and the first threading section 221 formed by the first sub-section 2211, the second sub-section 2212, the third sub-section 2213, and the fourth sub-section 2214 has a large size in the length direction of the band 10, thereby increasing the difficulty of the first threading section 221 passing through the hooking hole 103; since the fourth sub-section 2214 extends from the end of the third sub-section 2213 away from the second sub-section 2212 away from the fixed portion 21, in the thickness direction of the band 10, the point closest to the fixed portion 21 of the part of the first threading section 221 other than the first sub-section 2211 is the point closest to the fixed portion 21 of the third sub-section 2213, that is, the point closest to the fixed portion 21 of the third sub-section 2213 is the terminal point, and the terminal point is located on the first virtual plane M, and in addition, the hooking hole 103 can pass through the part of the hooking portion 22 located on the side of the first virtual plane M away from the fixed portion 21 by translation, that is, the hooking hole 103 can pass through the first sub-section 2211, the second sub-section 2212, the third sub-section 2213, and the fourth sub-section 2214 by translation, thereby reducing the risk of the hooking hole 103 being turned along the first threading section 221 and improving the convenience of the hooking of the hooking portion 22 and the hooking hole 103.
[0140] For example, the interface between the third sub-section 2213 and the fourth sub-section 2214 can refer to the straight line C.
[0141] In some embodiments, when the band 10 is in the unfolded state, the hooking portion 22 is provided with a fifth virtual plane Q, the fifth virtual plane Q is parallel to the first virtual plane M, and the hooking portion 22 forms a pressing section 2202 from the fifth virtual plane Q towards at least a part of the fixing portion 21; during the process of the pressing section 2202 penetrating the hooking hole 103, the interaction force between the pressing section 2202 and the hooking hole 103 is always arranged towards the fixing portion 21.
[0142] The fifth virtual plane Q is a virtual plane, and the hooking portion 22 can have no obvious structural identification or can have obvious structural identification, such as recess, protrusion, etc. The fifth virtual plane Q is parallel to the first virtual plane M.
[0143] The number of the fifth virtual plane Q can be one or more, the fifth virtual plane Q is perpendicular to the thickness direction of the band 10, the hooking portion 22 extends from the fifth virtual plane Q towards the fixing portion 21 to form the pressing section 2202, and the part of the hooking portion 22 between the pressing section 2202 and the fixing portion 21 does not meet the condition of the pressing section 2202; or, the part of the hooking portion 22 between the fifth virtual plane Q and the fixing portion 21 all meet the condition of the pressing section 2202, and the entire hooking portion 22 is the pressing section 2202.
[0144] In some examples, the part of the hooking portion 22 on the side of the fifth virtual plane Q away from the fixing portion 21 is a second penetrating section 2203; along the radial direction of the hooking hole 103, the size L2 of the part of the second penetrating section 2203 between any third virtual plane O and fourth virtual plane P is less than or equal to the size D of the hooking hole 103, the hooking hole 103 can pass through the second penetrating section 2203 by translation, and the hooking hole 103 can be sleeved on the pressing section 2202. Of course, the hooking portion 22 can also not include the second penetrating section 2203.
[0145] During the process of the hooking portion 22 penetrating the hooking hole 103, under the tension of the band 10, the contact point between the hole wall of the hooking hole 103 and the hooking portion 22 is E, and a tangent line L is drawn through the contact point E.
[0146] According to the physical force analysis, the force F of the hooking part 22 on the hole wall of the hooking hole 103 is perpendicular to the tangent line L, and according to the parallelogram law of force, the force F can be decomposed into a horizontal component F1 and a vertical component F2; and the vertical component F2 of the downward pressing segment 2202 always points to the fixing part 21, that is, the force F of the downward pressing segment 2202 always has a vertical component F2, and during the process that the downward pressing segment 2202 passes through the hooking hole 103, the vertical component F2 drives the hooking hole 103 to continue moving along the downward pressing segment 2202 towards the fixing part 21, so that the hooking part 22 can be more smoothly hooked in the hooking hole 103, the operation of hooking the hooking part 22 and the hooking hole 103 is simpler, and the stability and reliability of hooking are better.
[0147] For example, referring to Figures 4-6 As shown in the figure, the hooking part 22 is an arc-shaped part protruding away from the fixing part 21, the part of the outer peripheral wall of the hooking part 22 towards the fixing part 21 can guide the hooking hole 103 to move downwards towards the fixing part 21, the fifth virtual plane Q can be located at the end of the hooking part 22 away from the fixing part 21, and the part of the hooking part 22 between the fifth virtual plane Q and the fixing part 21 is the downward pressing segment 2202.
[0148] For example, referring to Figures 7-9 As shown in the figure, the first sub-segment 2211 and the connecting segment 222 are arc-shaped and protrude away from the fixing part 21, the second sub-segment 2212 is arc-shaped and protrudes away from the first sub-segment 2211, under the tension of the band 10, the second sub-segment 2212 can guide the hooking hole 103 to move away from the fixing part 21, and the connecting segment 222 can guide the hooking hole 103 to move downwards towards the fixing part 21, the fifth virtual plane Q can coincide with the first virtual plane M, and the connecting segment 222 forms the downward pressing segment 2202.
[0149] For example, referring to Figures 10-12 As shown in the figure, the first sub-segment 2211 and the connecting segment 222 are arc-shaped and protrude away from the fixing part 21, the second sub-segment 2212 is arc-shaped and protrudes away from the first sub-segment 2211, the third sub-segment 2213 is arc-shaped and protrudes away from the first sub-segment 2211, under the tension of the band 10, the third sub-segment 2213 and the connecting segment 222 can guide the hooking hole 103 to move downwards towards the fixing part 21, therefore, the fifth virtual plane Q can be the interface between the second sub-segment 2212 and the third sub-segment 2213 or a virtual plane located between the interface and the fixing part 21, and the third sub-segment 2213 and the connecting segment 222 form the downward pressing segment 2202.
[0150] For example, referring to Figure 13As shown, the first sub-section 2211 and the connecting section 222 are arc-shaped and protrude away from the fixing portion 21, the second sub-section 2212 is arc-shaped and protrudes away from the first sub-section 2211, the third sub-section 2213 is arc-shaped and protrudes away from the first sub-section 2211, and the fourth sub-section 2214 protrudes away from the second sub-section 2212; during the process that the hooking portion 22 passes through the hooking hole 103, the fourth sub-section 2214 does not contact the hooking hole 103, then under the tension of the belt body 10, the third sub-section 2213 and the connecting section 222 can guide the hooking hole 103 to move downward toward the fixing portion 21, therefore, the fifth virtual plane Q can be the boundary surface of the second sub-section 2212 and the third sub-section 2213 or a virtual plane located between the boundary surface and the fixing portion 21, and the third sub-section 2213 and the connecting section 222 form a downward pressing section 2202.

The fixed part is connected to the second end, and the hooking part protrudes from the surface of the fixed part along the thickness direction of the belt. When the belt is in the unfolded state, the hooking part is provided with a first virtual plane and a second virtual plane perpendicular to the thickness direction of the belt; the first virtual plane divides the hooking part into a first through section and a connecting section, the connecting section connects the fixing part and the first through section, and the second virtual plane intersects with the connecting section; the distance between the first virtual plane and the second virtual plane is equal to the depth of the hooking hole; The portion of the hook set located on the side of the second virtual plane opposite to the fixing part is the hook body. A third virtual plane and a fourth virtual plane are arbitrarily selected on the hook body. Both the third virtual plane and the fourth virtual plane are parallel to the first virtual plane. The distance between the third virtual plane and the fourth virtual plane is equal to the depth of the hook set hole. Along the radial direction of the hook hole, the size of the portion of the hook body located between any of the third virtual plane and the fourth virtual plane is less than or equal to the size of the hook hole.
2. The strap of claim 1, wherein: When the belt is in the unfolded state, the hook portion protrudes from the fixing portion and extends obliquely or bends toward the first end; The point on the end face of the hook portion that is closest to the fixing portion is the end point, and the end point is located in the first virtual plane.
3. The strap of claim 2, wherein: The hook portion is an arc-shaped portion that protrudes away from the fixing portion.
4. The strap of claim 1, wherein: The first threading section includes a first sub-segment and a second sub-segment. When the belt is in the unfolded state, the first sub-segment extends from the end of the connecting section away from the fixing part away from the fixing part and extends obliquely or bends toward the first end. The second sub-segment extends from the end of the first sub-segment away from the fixing part toward the fixing part and extends obliquely or bends toward the first end.
5. The strap of claim 4, wherein: The first threading section further includes a third sub-segment. When the belt is in the unfolded state, the third sub-segment extends or bends from the end of the second sub-segment away from the first sub-segment toward the fixing part and away from the first end.
6. The strap of claim 5, wherein: The first threading section further includes a fourth sub-segment. When the belt is in the unfolded state, the fourth sub-segment extends obliquely or bends from the end of the third sub-segment away from the second sub-segment, away from the fixing part and away from the first end.
7. The strap of any one of claims 4-6, wherein: Along the thickness direction of the belt, the point closest to the fixing part of the first through section other than the first sub-segment is the end point, and the end point is located in the first virtual plane.
8. The strap of any one of claims 1-6, wherein: When the belt is in the unfolded state, the hook portion is provided with a fifth virtual plane, the fifth virtual plane is parallel to the first virtual plane, and the hook portion forms a pressing section from the fifth virtual plane toward at least a portion of the fixing portion; During the process that the lower pressing section is arranged in the hooking hole, the interaction force between the lower pressing section and the hooking hole is always arranged towards the fixed part.
9. The strap of any one of claims 1-6, wherein: The number of the hooking holes is multiple, and multiple hooking holes form multiple columns of hooking holes, each column of hooking holes includes one or more hooking holes, and multiple columns of hooking holes are arranged at intervals along the length direction of the belt body.
