Description

Technical Field

[0001] This utility model relates to the field of large circular knitting machine technology, specifically to an adjustable triangular seat assembly. Background Technology

[0002] With the development of the textile industry, textile equipment is being updated and upgraded at an increasingly rapid pace. In circular knitting machines, the cam seats are installed in a ring on the upper layer of the frame. These cam seats are mainly used to hold different types of knitting needles, and the accuracy of their installation directly affects the positional relationship between the needles and the knitting needles.

[0003] In the triangular seat assembly, the vertical position of the slider is mainly adjusted by an adjusting knob. For example, patent publication number CN215440880U discloses an adjusting mechanism and a circular knitting machine with it. By using a pure Archimedean spiral adjusting knob, its unique geometric characteristics enable uniform and stable displacement transmission. However, traditional pure Archimedean spiral adjusting knobs have the following drawbacks: 1. The adjusting knob requires high machining precision, greatly increasing the machining difficulty and cost. 2. Direct force on the spiral easily leads to wear, affecting the adjustment accuracy.

[0004] In view of this, the applicant conducted in-depth research on the above-mentioned issues, which led to this case. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Please see the appendix Figure 1 -Appendix Figure 3 This utility model provides an adjustable triangular seat assembly, including a triangular seat 1, a slider 2, and an adjusting knob 3. The slider 2 is slidably connected to the triangular seat 1, and the rear end of the slider 2 has an inclined surface 21. The adjusting knob 3 is embedded in the triangular seat 1 and includes an adjusting shaft 4, a connecting sleeve 5, and a fixing sleeve 6. The front end of the adjusting shaft 4 has an adjusting cone surface that abuts against the inclined surface 21, and the rear end of the adjusting shaft 4 has an adjusting cap 41. The connecting sleeve 5 is sleeved on the adjusting shaft 4, and the fixing sleeve 6 is sleeved on the outside of the connecting sleeve 5 and is engaged with the connecting sleeve 5 by a retaining ring 7. The adjusting shaft 4 has a threaded section 42, and the connecting sleeve 5 has a threaded hole 51 that threadedly engages with the threaded section 42. By rotating the adjusting cap 41, the adjusting shaft 4 is driven to rotate, and the adjusting shaft 4 translates within the connecting sleeve 5, causing the adjusting cone surface to abut against the inclined surface 21, thereby finely adjusting the vertical position of the slider 2.

[0023] In this embodiment, the outer side wall of the connecting sleeve 5 is provided with a first groove 52, and the inner side wall of the fixing sleeve 6 is provided with a second groove 61. During installation, the retaining ring 7 is embedded in the first groove 52 and the second groove 61, thereby snapping the connecting sleeve 5 and the fixing sleeve 6 together. The outer side wall of the fixing sleeve 6 is provided with anti-slip ridges 62, which can increase friction and fix the fixing sleeve 6 and the connecting sleeve 5 in the mounting hole 12. The rear end face of the adjusting cap 41 is provided with a slot, which facilitates the use of tools to drive the adjusting shaft 4 to rotate. The front end face of the adjusting cap 41 is provided with a circular boss 411 that mates with the fixing sleeve 6. The circular boss 411 makes the engagement between the adjusting shaft 4 and the fixing sleeve 6 more secure, and the rotation of the adjusting shaft 4 is more stable. The front end of the connecting sleeve 5 is provided with a positioning hole 53 that communicates with the threaded hole 51. The positioning hole 53 allows the front end of the adjusting shaft 4 to pass through, further improving the positioning accuracy of the adjusting shaft 4.

[0024] In this embodiment, the triangular base 1 is provided with a sliding groove 11 for the slider 2 to slide along. The sliding groove 11 is arranged vertically, and the slider 2 can move up and down along the sliding groove 11. The side wall of the triangular base 1 is provided with a mounting hole 12 for mounting an adjustment knob 3. The mounting hole 12 communicates with the sliding groove 11. A positioning plate 13 is embedded in the sliding groove 11. The positioning plate 13 is detachably inserted into the side wall of the sliding groove 11, and the positioning plate 13 limits the position of the slider 2. Furthermore, the side wall of the sliding groove 11 is provided with a guide groove 14, and the side wall of the slider 2 is provided with a guide slider 2 that slides with the guide groove 14. The guide slider 2 cooperates with the guide groove 14 to limit the slider 2 in the front-back direction and make the slider 2 slide more smoothly. The bottom surface of the slider 2 is provided with a receiving hole 22, and a spring 23 is provided in the receiving hole 22. The lower end of the spring 23 abuts against the positioning plate 13. When the rotating adjustment shaft 4 moves forward, the slider 2 moves downward and compresses the spring 23; when the rotating adjustment shaft 4 moves backward, the slider 2 is driven to move upward and reset under the elastic force of the spring 23.

[0025] The working principle of this utility model is as follows: First, install the connecting sleeve 5 inside the mounting hole 12. Then, connect the retaining ring 7 and the fixing sleeve 6 to the connecting sleeve 5, fixing the connecting sleeve 5 and the fixing sleeve 6 inside the mounting hole 12. Pass the adjusting shaft 4 through the fixing sleeve 6 and the connecting sleeve 5, threading the adjusting shaft 4 and the connecting sleeve 5 together, thus completing the installation of the adjusting knob 3. When adjusting the slider 2, rotating the adjusting knob 3 controls its forward or backward movement, thereby driving the slider 2 to descend or ascend.

[0026] This invention provides an adjustable triangular base assembly 1. It offers the following advantages: The adjusting knob 3 is divided into three parts, facilitating its manufacturing. Furthermore, the height of the slider 2 is adjusted via a threaded connection, further reducing the machining precision and cost of the adjusting knob 3. In addition, the adjusting knob 3 has a simple structure, is easy to maintain and replace, and has a longer service life.
