[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-4 , the present invention provides a technical solution for a clamp for a water jet loom: a clamp for a water jet loom, including a clamp body 1, a push rod 2, a movable clamping piece 5 and a static clamping piece 7. The clamp body 1 is detachably connected to the push rod 2, and the push rod 2 in the installed state slides inside the clamp body 1. The outer and inner sides of the clamp body 1 and the push rod 2 are provided with a disassembly and assembly mechanism 6, and the disassembly and assembly mechanism 6 is used to assist the disassembly or installation of the movable clamping piece 5 and the static clamping piece 7;

[0025] The disassembly and assembly mechanism 6 includes a cover plate assembly and a limit block assembly;

[0026] The movable clamping piece 5 is detachably connected to the clamp body 1 through the cover plate assembly;

[0027] The static clamping piece 7 is detachably connected to the push rod 2 through the limit block assembly.

[0028] Please pay special attention to Figure 1 , a spacer 3 is fixedly connected to the surface of the push rod 2, a spring 4 is sleeved on the outer wall of the push rod 2, and both ends of the spring 4 are fixedly connected to the spacer 3 and the clamp body 1 respectively.

[0029] In this embodiment: the movable clamping piece 5 connected to the push rod 2 clamps the yarn through the elastic force of the spring 4, and the push rod 2 overcomes the elastic force of the spring 4 under the drive of the cam structure of the water jet loom to separate the movable clamping piece 5 and the static clamping piece 7 and thus loosen the yarn.

[0030] Please pay special attention to Figure 2 , the cover plate assembly includes a cover plate 601, a bolt 602, a threaded hole 603 and a rotating shaft 609;

[0031] The cover plate 601 is rotatably connected to the clamp body 1 through the rotating shaft 609, the bolt 602 is rotatably installed on the outside of the cover plate 601, and the threaded hole 603 is opened on the surface of the clamp body 1 and extends into its interior.

[0032] In this embodiment: When it is necessary to install the static clamping piece 7, first rotate the cover plate 601 counterclockwise around the rotating shaft 609, so that the cover plate 601 in the counterclockwise rotation state makes the placement groove of the gripper body 1 in an open state. Then place the static clamping piece 7 inside the placement groove of the gripper body 1, and rotate the cover plate 601 clockwise around the rotating shaft 609, so that the cover plate 601 in the clockwise rotation state makes the placement groove of the gripper body 1 in a closed state. Then thread the screw hole 603 and the bolt 602, so that the tightened bolt 602 locks and limits the rotation of the cover plate 601. Then the static clamping piece 7 is limited and installed inside the placement groove of the gripper body 1, and thus the installation of the static clamping piece 7 is completed.

[0033] Please refer specifically to Figure 2 , the screw hole 603 is threadedly connected with the bolt 602, and the tightened bolt 602 is used to lock and limit the rotation of the cover plate 601.

[0034] In this embodiment: Thread the screw hole 603 and the bolt 602, so that the tightened bolt 602 locks and limits the rotation of the cover plate 601. Then the static clamping piece 7 is limited and installed inside the placement groove of the gripper body 1.

[0035] Please refer specifically to Figure 3 , the limiting block assembly includes a groove 604, a limiting block 605, a connecting shaft 606, a torsion spring 607 and a limiting ring 608;

[0036] The groove 604 is opened on the surface of the push rod 2 and extends into it. The connecting shafts 606 are formed at both ends of the limiting block 605, and the connecting shafts 606 are rotatably connected with the groove 604. The two ends of the torsion spring 607 are respectively engaged with the limiting block 605 and the groove 604, and the torsion spring 607 in the twisted state is used to drive the limiting block 605 to rotate and reset. The limiting ring 608 is fixedly connected to the outer wall of the push rod 2.

[0037] In this embodiment: When it is necessary to install the movable clamping piece 5, sleuth the movable clamping piece 5 on the surface of the push rod 2, so that the movable clamping piece 5 contacts the limiting block 605. And since the end face of the limiting block 605 in contact with the movable clamping piece 5 is of an inclined surface structure, the movable clamping piece 5 is extruded by the inclined surface of the limiting block 605, so that the limiting block 605 rotates into the groove 604 around the connecting shaft 606 and extrudes the torsion spring 607. The torsion spring 607 is distorted by the force. When the movable clamping piece 5 completely covers the limiting block 605, the movable clamping piece 5 is separated from the limiting block 605, and the twisted torsion spring 607 drives the limiting block 605 to rotate and reset. Furthermore, the limiting block 605 in the reset state and the limiting ring 608 cooperate to limit the installed movable clamping piece 5, and thus the installation of the movable clamping piece 5 is completed.

[0038] Please refer with emphasis to Figure 3 , the end face of the limit block 605 in contact with the moving clip 5 has an inclined surface structure, and both the limit block 605 and the limit ring 608 are used to limit the moving clip 5 in the installed state.

[0039] In this embodiment: the twisted torsion spring 607 drives the limit block 605 to rotate and reset, and then the limit block 605 in the reset state cooperates with the limit ring 608 to limit the moving clip 5 in the installed state.

[0040] Working principle: When the static clip 7 needs to be installed, first rotate the cover plate 601 counterclockwise around the rotating shaft 609, so that the cover plate 601 in the counterclockwise rotation state makes the placement groove of the gripper body 1 in an open state. Then place the static clip 7 inside the placement groove of the gripper body 1, and rotate the cover plate 601 clockwise around the rotating shaft 609, so that the cover plate 601 in the clockwise rotation state makes the placement groove of the gripper body 1 in a closed state. Then thread the screw hole 603 and the bolt 602, so that the tightened bolt 602 locks and limits the rotation of the cover plate 601, and the static clip 7 is limited and installed inside the placement groove of the gripper body 1, thus the installation of the static clip 7 is completed;

[0041] When the moving clip 5 needs to be installed, sleeved the moving clip 5 on the surface of the tappet 2, so that the moving clip 5 contacts the limit block 605. And because the end face of the limit block 605 in contact with the moving clip 5 has an inclined surface structure, the moving clip 5 is extruded by the inclined surface of the limit block 605, so that the limit block 605 rotates into the groove 604 around the connecting shaft 606, and extrudes the torsion spring 607, and the torsion spring 607 is distorted by the force. When the moving clip 5 completely covers the limit block 605, the moving clip 5 separates from the limit block 605, and the twisted torsion spring 607 drives the limit block 605 to rotate and reset. Then the limit block 605 in the reset state cooperates with the limit ring 608 to limit the moving clip 5 in the installed state, thus the installation of the moving clip 5 is completed. Through the above structure, it is convenient to disassemble or install the moving clip 5 and the static clip 7. Then the moving clip 5 connected to the tappet 2 clamps the yarn by the elastic force of the spring 4 with the static clip 7, and the tappet 2 overcomes the elastic force of the spring 4 under the drive of the cam structure of the water jet loom to separate the moving clip 5 and the static clip 7 and then relax the yarn.
