[0022] Figures 1-3 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-3 The present invention will be further described below.

[0023] like Figures 1-3 As shown, a height adjustment tool for a heald frame of a rapier loom (hereinafter referred to as the height adjustment tool) includes a support rod 6 and a support column 12, which are hinged together. A transition connecting rod 9 is also provided between the support rod 6 and the support column 12. The upper end of the transition connecting rod 9 is hinged to the end of the support rod 6, and the bottom of the transition connecting rod 9 is hinged to the top of the support column 12.

[0024] A slot is provided at the end of the support rod 6. After the upper end of the transition connecting rod 9 is inserted into the slot at the end of the support rod 6, the transition connecting rod 9 and the support rod 6 are hinged by the first fastening bolt 7 that passes through radially. A first lever 8 is rotatably connected to one end of the first fastening bolt 7. After the first fastening bolt 7 passes through the transition connecting rod 9 and the support rod 6, a nut is installed. When the first lever 8 is moved, the first fastening bolt 7 and the nut can lock the transition connecting rod 9 and the support rod 6.

[0025] A latch is also provided at the top of the support column 12. After the lower end of the transition connecting rod 9 is inserted into the latch at the top of the support column 12, the transition connecting rod 9 and the support column 12 are hinged by the radially penetrating second fastening bolt 11. A second lever 10 is rotatably connected to one end of the second fastening bolt 11. A nut is installed on the second fastening bolt 11 after it passes through the transition connecting rod 9 and the support column 12. When the second lever 10 is moved, the second fastening bolt 11 and the nut can lock the transition connecting rod 9 and the support column 12.

[0026] As can be seen from the above, the two-section hinge structure formed by the support rod 6, the transition connecting rod 9 and the support column 12 can be used to release the locking state of the hinge joint of the support rod 6, the transition connecting rod 9 and the support column 12 by rotating the first lever 8 and the second lever 10 in the opposite direction after use, and then fold it, so as to facilitate the taking, putting away and storing of this height adjustment tool.

[0027] A heald frame adjusting rod 5 is provided below the support rod 6. The length of the heald frame adjusting rod 5 is less than that of the support rod 6, and it is arranged parallel to the support rod 6. A height adjusting component 1 is also provided on both sides of the heald frame adjusting rod 5. The upper part of the height adjusting component 1 passes through the support rod 6. Through the heald frame adjusting rod 5, the support rod 6, and the height adjusting components 1 on both sides, an adjusting frame for accommodating the heald frame is formed. The height of the heald frame adjusting rod 5 can be adjusted by the height adjusting components 1 on both sides, thereby realizing the adjustment of the heald frame height.

[0028] The height adjustment assembly 1 includes an adjustment bolt 15, which passes radially through the heald frame adjustment rod 5 and the support rod 6. The hexagonal nut at the end of the adjustment bolt 15 is locked at the bottom of the heald frame adjustment rod 5. A fastening nut 14 that is threadedly connected to the adjustment bolt 15 is also provided on the surface of the heald frame adjustment rod 5. The heald frame adjustment rod 5 and the adjustment bolt 15 are fixed by the two nuts on the upper and lower parts of the heald frame adjustment rod 5.

[0029] An adjusting nut 13 is threaded onto the upper part of the adjusting bolt 15. The adjusting nut 13 is located on the upper part of the support rod 6. By rotating the support rod 6, the relative position between the adjusting nut 13 and the adjusting bolt 15 can be changed, thereby realizing the adjustment of the height of the heald frame adjusting rod 5.

[0030] A locking mechanism is also provided between the height adjustment components 1 on both sides, which is used to lock with the edge of the loom when adjusting the height of the heald frame. The locking mechanism is installed on the support rod 6 and includes a fixed frame 3 and a fixed pressure plate 2 arranged opposite to each other. The fixed pressure plate 2 is located on the upper part of the support rod 6, and the fixed frame 3 is locked on the lower part of the support rod 6. A groove matching the bottom contour of the support rod 6 is opened in the middle of the upper surface of the fixed frame 3. The bottom of the support rod 6 is placed in the groove. After the fixed pressure plate 2 covers the upper part of the support rod 6, it is connected to the front and rear ends of the fixed frame 3 by two bolts, respectively, to achieve fastening between the fixed plate 2 and the support rod 6.

[0031] A mounting frame 4 is also provided at the lower part of the fixed frame 3. The mounting frame 4 is a frame with an open bottom. The top of the mounting frame 4 is fixed to the bottom of the fixed frame 3. The latch at the bottom of the mounting frame 4 is used for mounting and connecting with the upper edge of the loom.

[0032] The specific working process and working principle are as follows:

[0033] Rotate the first lever 8 and the second lever 10, and adjust the relative angle between the support rod 6, the transition connecting rod 9 and the support column 12 so that the support rod 6 is in a horizontal state and perpendicular to the support column 12, and then lock it by the first lever 8 and the second lever 10.

[0034] Then, the heddle frame adjusting rod 5 is passed under the heddle frame, that is, the heddle frame is placed into the adjusting frame formed between the heddle frame adjusting rod 5 and the support rod 6, and at the same time, it is clamped to the upper edge of the loom by the clamping frame 4. Since the heddle frame is placed inside the adjusting frame, its support rod 6 is actually clamped to the loom by the clamping frame 4, thus limiting the adjusting frame, so that it can be supported by the support column 12.

[0035] Finally, by rotating the adjusting nut 13 to adjust its relative position with the adjusting bolt 15, the height of the heddle frame adjusting rod 5 can be adjusted.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
