[0034] The technical scheme of the utility model will be described in detail below with specific examples. The following specific examples can be combined or replaced according to actual conditions, and the same or similar concepts or processes may not be described in some examples.

[0035] As shown in Figure 1 and Figure 2 The utility model provides a heald, including the rod body 1 and the guide eye 3, the rod body 1 is integrally cold rolled from single steel wire, the rod body 1 includes the cold rolled section 2 in the middle part, the cold rolled section 2 includes the first part 21 and the second part 22 that extend side by side along the length direction of the rod body 1, the both ends of the first part 21 and the second part 22 are spirally wound to form the connecting part, the connecting part connects the rod body 1, the middle part of the first part 21 and the second part 22 forms the mounting hole 23, the first part 21 and the second part 22 are gathered to the central position under the winding of both ends, the guide eye 3 is located in the mounting hole 23 and abuts the middle part of the first part 21 and the second part 22, under the tendency of the first part 21 and the second part 22 gathering to the middle, the guide eye 3 abuts in the middle part of the first part 21 and the second part 22, improve the stability of the guide eye 3 before fixed installation, reduce the possibility of the guide eye 3 separating from the mounting hole 23 and the rod body 1 in the conveying process, and further improve the production efficiency of the heald.

[0036] In the embodiment, the structure of the first part 21 and the second part 22 is symmetrically arranged relative to the rod body 1, so that the tendency of the first part 21 and the second part 22 gathering to the middle is comparable, avoiding that the single side strength is too large to cause the center of the mounting hole 23 to deviate from the length direction of the rod body 1.

[0037] Specifically, the first part 21 includes two first connecting parts 211 and a first intermediate part 212 arranged between the two first connecting parts 211, and the second part 22 includes two second connecting parts 221 and a second intermediate part 222 arranged between the two second connecting parts 221; the two first connecting parts 211 and the two second connecting parts 221 are spirally wound one by one to form connecting parts, one end of the connecting parts is connected with the first intermediate part 212 and the second intermediate part 222, and the other end is connected with the rod body 1, the first intermediate part 212 and the second intermediate part 222 form a mounting hole 23 between the two connecting parts, after the guide eye 3 is placed in the mounting hole 23, the first intermediate part 212 and the second intermediate part 222 are both abutted on the guide eye 3, so as to stabilize the guide eye 3 in the mounting hole 23.

[0038] In order to reduce the possibility that the mounting hole 23 is not matched with the guide eye 3, as shown in Figure 3 , the distance between the two end faces of the first intermediate part 212 in the length direction of the rod body 1 is L1, the distance between the two end faces of the first connecting part 211 in the length direction of the rod body 1 is L2, and L2≦L1≦2*L2; specifically, the setting of L1≦2*L2 avoids that the mounting hole 23 formed by the first intermediate part 212 and the second intermediate part 222 is too large, which causes the guide eye 3 to be unable to be placed in the mounting hole 23, thereby affecting the stability of the guide eye 3 in the mounting hole 23; L1≧L2 avoids that the mounting hole 23 is too small, and a large force is required to press the guide eye 3 into the mounting hole 23 when the guide eye 3 is placed in the mounting hole 23, which is easy to damage the outer peripheral wall of the guide eye 3 and also affects the placement efficiency of the guide eye 3.

[0039] In order to improve the accuracy after the guide eye 3 is installed, as shown in Figure 3 , the first intermediate part 212 is provided with a circular arc, which avoids the occurrence of edges on the inner side of the first intermediate part 212 and affects the installation of the guide eye 3; similarly, the second intermediate part 222 is also provided with a circular arc; and the circular arc formed by the first intermediate part 212 and the second intermediate part 222 is an optimal arc, which makes the size of the mounting hole 23 suitable and facilitates the placement of the guide eye 3 in the mounting hole 23.

In addition, the connection between the second connecting part 221 and the second intermediate part 222 is also smooth.

[0041] The two ends of the first intermediate part 212 form an acute angle structure with the second part 22, as shown in Figure 3As shown, specifically, the first intermediate part 212 and the second intermediate part 222 form an acute angle structure, and the angle a of the acute angle structure satisfies 20°≦a≦50; specifically, the angle of the acute angle structure formed by the two ends of the first intermediate part 212 and the second intermediate part 222 is set to a≦50°, so as to avoid that the angle is too large and the guide eye 3 cannot be well stabilized after being placed in the mounting hole 23; 20°≦a, so as to avoid that the mounting hole 23 is too small and the difficulty of placing the guide eye 3 in the mounting hole 23 is increased; the setting of 20°≦a≦50° gives the first intermediate part 212 and the second intermediate part 222 a proper folding range, and improves the stability of the guide eye 3 in the mounting hole 23.

[0043] In the embodiment, the assembly space 24 is defined between the support rod 31 and the first part 21 and the second part 22, specifically, since the first intermediate part 212 and the second intermediate part 222 are both arc-shaped, the assembly space 24 is formed between the outer side of the support rod 31 and the inner side of the first intermediate part 212 and the second intermediate part 222 after the support rod 31 is supported on the first intermediate part 212 and the second intermediate part 222, and after the guide eye 3 is placed, the assembly space 24 is filled with filling material, so as to stably install the guide eye 3 between the first intermediate part 212 and the second intermediate part 222, and the filling material is usually tin liquid which can better fix the guide eye 3.
