[0035] The names of the messages or information exchanged between the multiple devices in this embodiment of the invention are for illustrative purposes only and are not intended to limit the scope of these messages or information.

[0036] See Figures 1 to 3 The present invention provides a static press column nut locking device, including a preload nut 3 and a connecting seat 4 that are threaded to the end of the column 1 of the static press. The two ends of the connecting seat 4 are respectively fixedly connected to the corresponding preload nut 3.

[0037] With the above structure, the pre-tightening nut 3 and the connecting seat 4 can be used to fix the pre-tightening nut 3 on the adjacent column 1 to the connecting seat 4, thereby preventing the pre-tightening nut 3 from loosening and ensuring the normal operation of the static press.

[0038] In one embodiment, see Figures 2 to 4 The connecting seat 4 includes symmetrically arranged connecting plates 41, with multiple support plates 42 positioned between the two connecting plates 41. Both ends of the connecting plates 41 are fixedly connected to the pre-tightening nuts 3. In practical applications, the symmetrical arrangement of the connecting plates 41 and the support plates 42 ensures the connection strength of the connecting seat 4 and reduces its weight.

[0039] The two ends of the connecting plate 41 are circular plates 411. In practical applications, the circular plates 411 facilitate the engagement of the two ends of the connecting plate 41 with the pre-tightening nuts 3 on the corresponding columns 1.

[0040] Multiple fixing holes 412 are passed through both ends of the connecting plate 41. The two ends of the connecting plate 41 are fixedly connected to the pre-tightening nut 3 by bolts passing through the fixing holes 412. The multiple fixing holes 412 can be arranged in an array along the outer periphery of the circular plate 411. In practical applications, the fixing holes 412 and bolts can be used to fix the ends of the two connecting plates 41 to the corresponding pre-tightening nuts 3 at the same time to prevent the pre-tightening nuts 3 from loosening.

[0041] In one embodiment, see Figure 1 , Figure 2 , Figure 3 and Figure 5 A jack 5 is installed between the top of the static press and the connecting seat 4. The output end of the jack 5 is used to press the connecting seat 4, so that the thrust on the connecting seat 4 is transmitted to the preload nut 3. In actual use, with the jack 5 installed, after the output end of the jack 5 extends and presses the connecting seat 4, the pressing force can be transmitted to the preload nut 3 by the fixed connection between the connecting seat 4 and the preload nut 3, so that the preload nut 3 is subjected to an upward pulling force, thereby increasing the tension of the preload nut 3 and further preventing the preload nut 3 from loosening.

[0042] A transition seat 6 is provided between the jack 5 and the connecting seat 4, so that the force output by the jack 5 is transmitted to the connecting seat 4 through the transition seat 6. In practical applications, the transition seat 6 can prevent the jack 5 from acting directly on the connecting seat 4, thereby protecting the connecting seat 4.

[0043] The transition seat 6 includes a transition column 61, with a thrust plate 62 at one end of the transition column 61. The thrust plate 62 faces the connecting seat 4, and its diameter is larger than that of the transition column 61. The transition column 61 is matched with the output end of the jack 5. In practical applications, the cooperation between the transition column 61 and the thrust plate 62 ensures that one end of the transition seat 6 matches the output end of the jack 5, while increasing the output area at the other end to prevent stress concentration and thus protect the connecting seat 4.

[0044] A reinforcing rib 63 is provided between the thrust plate 62 and the transition column 61. In practical applications, the reinforcing rib 63 can improve the strength of the connection between the thrust plate 62 and the transition column 61.

[0045] In one embodiment, see Figure 1 The column 1 of the static press is threadedly connected to a column locking nut 2, and a preload nut 3 is located between the column locking nut 2 and the connecting seat 4. In practical application, the column locking nut 2 is the existing column locking nut on the column 1 of the static press. This column locking nut 2 can be used or not, depending on the actual usage. When the column locking nut 2 is used, it locks the top of the static press to the column 1. The preload nut 3 and the connecting seat 4 work together to tighten the column locking nut 2, preventing it from loosening and ensuring its locking function. When the column locking nut 2 is not used, the preload nut 3 can be used as the column locking nut 2.

[0046] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.
