Specific embodiment

To keep the purpose of this utility model, technical solution and advantage clearer, below by the technology to the utility model Scheme is described in detail.Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not before making creative work Obtained all other embodiment is put, the range that the utility model is protected is belonged to.

Present embodiment is designed to provide a kind of heald, sets square for the cross section of the connection strap in harness eye portion Shape by keeping the long side of rectangle parallel with yarn, and makes transition face extend to the outside with harness eye portion along the width direction of heald rod Edge is concordant, increases the contact length between harness eye portion and yarn, reduces scratch of the harness eye portion to yarn, avoids above yarn The slurry of attachment falls off, and solves the problems, such as that yarn is easy the electrostatic that fluffed.The purpose of present embodiment, which also resides in, to be mentioned For a kind of weaving loom with the heald.

Hereinafter, being illustrated referring to attached drawing to embodiment.In addition, embodiments illustrated below is not to recorded in claim Utility model content rise any restriction effect.In addition, the full content of composition represented by following example is not limited to conduct Necessary to the solution of utility model documented by claim.

Referring to Fig.1~7, a kind of structural schematic diagram of heald in some exemplary embodiments is shown.The present embodiment provides A kind of heald, the heald rod 1 including laminated structure, the heald end loop portion 2 for being connect with comprehensive item and the harness eye portion 3 passed through for yarn, The both ends of heald rod 1 are arranged in heald end loop portion 2, and the middle part of heald rod 1 is arranged in harness eye portion 3.Harness eye portion 3 includes two companies being parallel to each other Narrow bars 4, connection strap 4 is axially extending along heald rod 1, and the both ends of two connection straps 4 are connect with the end of heald rod 1, connects at two The through-hole passed through for yarn is formed between item 4.The cross section of two connection straps 4 is rectangle, two long sides and the heald rod 1 of rectangle Width direction is parallel, and the central axis of two connection straps 4 all has along the thickness direction of heald rod 1 and the width direction of heald rod 1 Spacing, and two connection straps 4 also have gap along the relatively close one side of the thickness direction of heald rod 1, i.e. two connection straps 4 are mutual Be staggered the space to be formed and be passed through for yarn.Changeover portion 5 is provided between harness eye portion 3 and heald rod 1, changeover portion 5 has by the first mistake Cross plane 6, the transition face that the second transition plane 7 and third transition plane 8 are sequentially distributed and link together, one side of transition face It is connect with the smooth surface of heald rod 1, another side extends to the end of connection strap 4, and transition face is extended to along the width direction of heald rod 1 Concordant with the external margin in harness eye portion 3, First Transition plane 6, the second transition plane 7 and third transition plane 8 are plane, just In processing, processing cost is reduced.So set, adding somewhat to the thickness in harness eye portion 3, harness eye portion 3 and yarn are increased Contact length between line reduces scratch of the harness eye portion 3 to yarn, avoids falling off for the slurry that yarn adheres to above, solution Yarn of having determined be easy fluffed electrostatic the problem of, improve the quality and production efficiency of cloth cover product.

For convenience of the description to 3 structure of harness eye portion, first each surface of two connection straps 4 is defined, reference Fig. 5, Two connection straps 4 are defined as the first plane 9 along the face that 1 thickness direction of heald rod is relatively distant from below, by two connection straps 4 along comprehensive The relatively close face of 1 thickness direction of bar is defined as the second plane 10, and two connection straps 4 are relatively distant from along 1 width direction of heald rod Face be defined as third plane 11, two connection straps 4 are defined as fourth plane along the relatively close face of 1 width direction of heald rod 12.In an implementation, as shown in fig. 6, having gap between above-mentioned two second plane 10, yarn is located in this gap, and with it is upper Two long sides for stating rectangle are parallel to each other, and keep yarn more smooth when passing through harness eye portion 3, increase yarn and when harness eye portion 3 contacts Contact length, reduce scratch of the harness eye portion 3 to yarn, avoid falling off for the slurry that yarn adheres to above, solve yarn Line be easy fluffed electrostatic the problem of.For the reliability of structure for guaranteeing harness eye portion 3, it need to guarantee the thickness of connection strap 4, that is, guarantee The bond length of above-mentioned two rectangle, due between two the second planes 10 have gap, so when need to make two the first planes 9 it Between distance be greater than the thickness of heald rod 1, but to avoid having an impact between the heald and the heald of adjacent position, also need to control The distance between two first planes 9 will not be excessive.There are gap, and two fourth planes between above-mentioned two fourth plane 12 Gap between 12 is greater than the gap between two the second planes 10, can be by yarn from two of harness eye portion 3 the in threading yarn Gap between four planes 12 passes through, and be located at after so that yarn is rotated by a certain angle relative to two connection straps 4 two it is second flat Between face 10, the size in hole of entrying is increased, convenient for entrying.

In preferred embodiment, the both ends of First Transition plane 6 are connect with the smooth surface of the first plane 9 and heald rod 1 respectively, The relative edge on one side that third transition plane 8 is connected with the second transition plane 7 extends to concordant with third plane 11, increases Contact length between two short sides and yarn in harness eye portion 3 further reduces scratch of the harness eye portion 3 to yarn.

In implementation, the second transition plane 7 and third transition plane 8 are triangle, reference Fig. 5, First Transition plane 6, Second transition plane 7 and the adjacent side of third transition plane 8 link together, and are smoothly connected with heald rod 1 and harness eye portion 3. The top of second transition plane 7 is connect with the bottom edge end of third transition plane 8, the top of third transition plane 8 and the second mistake The bottom edge end connection of plane 7 is crossed, the bottom edge of third transition plane 8 is connect with the smooth surface of heald rod 1, third transition plane 8 The one end on bottom edge connect with First Transition plane 6, the other end extends to third plane 11；Second transition plane 7 is obliquely installed, The one end on its bottom edge is connect with First Transition plane 6, and the other end extends to third plane 11.The First Transition on 5 two sides of changeover portion Be parallel to each other between plane 6, be parallel to each other between the second transition plane 7, be parallel to each other between third transition plane 8, as Fig. 3~ Shown in 4.

In the present embodiment, is passed through from harness eye portion 3 due to yarn and carried out in the inside in harness eye portion 3 relative to harness eye portion 3 It is mobile, to reduce scratch of the harness eye portion 3 to yarn, make to connect between each medial surface in harness eye portion 3 by smooth curved surface, harness eye It is connected between the medial surface in portion 3 and the lateral surface in harness eye portion 3 by smooth curved surface, i.e. the rib that can be arrived with yarn contacts of harness eye portion 3 Angular position is connected by smooth curved surface.

As optional embodiment, to be provided with and being used at the both ends of heald rod 1 convenient for the heald to be mounted on comprehensive item Automatically point comprehensive hole 13 gaited.Further to cooperate a point comprehensive hole 13, realization is gaited automatically, be additionally provided at the both ends of heald rod 1 and The iron wire hole 14 for dividing comprehensive hole 13 to be used cooperatively, iron wire hole 14 are located between heald end loop portion 2 and point comprehensive hole 13.
