[0020] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0021] like Figure 1 A loom heald shown includes a heald body 1, which is made of stainless steel and has a circular cross-section. The middle of the heald body 1 has an opening, in which a thin sheet-like wire guide 2 is fixed. At least one end of the two ends of the heald body 1 has an elastic locking structure 3 for convenient installation of a draw rope.

[0022] Specifically, combined Figure 2-5 As shown, the opening is roughly in a diamond shape, and the size of the opening gradually increases from both ends to the center, with two symmetrical branches 4, the branch 4 is a long strip structure, and its cross-sectional size is smaller than the cross-sectional size of the heald body 1. The two branches 4 have parallel horizontal sections and inclined sections connected to the heald body 1. The two branches are surrounded by a diamond-like shape that adapts to the outer contour of the thin sheet-like guide wire sheet, which is convenient for the embedded welding of the thin sheet-like guide wire sheet 2. The thin sheet-like guide wire sheet 2 is arranged between the two branches 4, and the center of the thin sheet-like guide wire sheet 2 has a guide wire hole 201. The thin sheet-like guide wire The middle section of the sheet 2 is rectangular, and its left and right ends are arc-shaped. The thickness of the thin sheet-like wire guide sheet 2 is less than or equal to the maximum diameter of the circle where the branch 4 is located. The two side end surfaces of the thin sheet-like wire guide sheet 2 in the width direction are welded integrally with the inner end surfaces of the two branches 4. The two ends of the thin sheet-like wire guide sheet 2 in the length direction respectively have an outwardly inclined avoidance plane 202 that can avoid hooking the textile thread. The thickness of the avoidance plane 202 gradually decreases from one end close to the guide hole 201 to the other end away from the guide hole 201. The inclined structure of the avoidance plane 202 can prevent the textile thread from being damaged.

[0023] In addition, the two side end faces in the width direction of the thin sheet-like guide wire sheet 2 have inwardly recessed positioning grooves 203, the cross-section of the branch 4 is fan-shaped, and its inner end face has a positioning strip 401 that can be inserted into the positioning groove 203. Through the matching structure of the positioning groove 203 and the positioning strip 401, the thin sheet-like guide wire sheet 2 and the branch 4 can be accurately positioned during welding, and then the gap between the thin sheet-like guide wire sheet 2 and the branch 4 is welded by laser.

[0024] Combination Figure 6 As shown, the elastic locking structure has a clamping section 301 capable of clamping the draw cord, a functional section 302 arched outward in a diamond shape, and a closing section 303 fitted with the main body of the heald. The clamping section 301 has a U-shaped clamping groove with an opening gradually decreasing until it is smaller than the diameter of the draw cord. The clamping section 301 adopts an inwardly bent elastic locking structure, which can lock the draw cord without the need for a special friction structure. The closing section 303 bends in the direction close to the main body of the heald to avoid damage to the silk thread.

[0025] The loom heald makes maximum and effective use of raw materials. The main body of the heald is made of stainless steel wire without waste. Stainless steel wires of different grades and specifications can be selected to meet the performance requirements of different looms for the main body of the heald, such as high elasticity, high strength, and water-proofness. Similarly, the selection of the wire guide can also take into account the wear resistance requirements. In addition, the structure determines that the force on the wire guide is reduced to the minimum state, and other weldable wear-resistant materials can be selected to further extend the service life of the heald, thereby effectively reducing the cost of use.

[0026] It should be noted that the parts not involved in the present invention are the same as the existing technology or can be implemented by using the existing technology.

[0027] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
