[0002] In modern parking lot management systems, parking barriers are key equipment for controlling vehicle access, and their stability and reliability directly affect the management efficiency and safety of parking lots. The screw rod is an important component that drives the gate rod up and down in the gate machine, and its fixing method is crucial to the overall performance and operational stability of the gate machine.

[0003] In traditional parking barriers, the screw fixing method usually involves complex processing steps, including turning steps and threads on the end of the screw to match the special screw end base and screw locking nut. Although this fixing method can achieve a stable installation of the screw, it has significant disadvantages: first, the processing process is cumbersome, requiring high-precision machine tools and skilled operating skills, resulting in increased manufacturing costs. For this reason, we provide a screw chuck to solve the above problems. Utility Model Content

[0026] like Figure 1 —The embodiment shown in 5.

[0027] A screw chuck comprises a screw 1, a chuck 2, wherein the chuck 2 is located at the end of the screw 1; a threaded rib 5, wherein the threaded rib 5 is arranged in the inner hole of the chuck 2, and the shape of the threaded rib 5 is adapted to the outer surface of the screw 1; and a stop bolt 3, wherein the stop bolt 3 passes through the chuck 2 to be connected with the threaded rib 5 to fix the screw 1 and the chuck 2.

[0028] See also Figure 1 As shown, the present application mainly fixes the lead screw 1 by fixing the chuck 2 to the lead screw 1 and clamping the chuck 2. Compared with the existing threaded connection using a locking nut and the end of the lead screw 1 and a matching base, the present application uses the chuck 2 to clamp and fix the chuck 2 to the lead screw 1 by a stop bolt 3, which is more convenient and does not require turning steps and threads on the end of the lead screw 1. Therefore, the processing cost of the lead screw 1 is greatly reduced and the installation efficiency is also improved.

[0029] A connecting hole 6 for the anti-rotation bolt 3 to pass through is formed on one side of the clamp 2 .

[0030] See also Figure 2 As shown, in this embodiment, the stop hole 4 is a threaded hole. Specifically, the connecting hole 6 can be a through hole. The stop bolt 3 passes through the connecting hole 6 and extends to the position of the stop hole 4 and is threadedly connected to the stop hole 4, thereby realizing the connection between the chuck 2 and the screw 1 to prevent the screw 1 from rotating.

[0031] The clamp 2 includes a first clamp body 21 and a second clamp body 22 . The first clamp body 21 and the second clamp body 22 are detachably fixedly connected. When the first clamp body 21 and the second clamp body 22 are connected together, the threaded rib 5 is formed.

When the first clamp body 21 and the second clamp body 22 are combined and connected together, a full circle is formed between the two. The threaded ribs 5 are arranged on the inner wall of the full circle. When the screw 1 is clamped by the first clamp body 21 and the second clamp body 22, the threaded ribs 5 cooperate with the thread lines or thread grooves on the outer surface of the screw 1, thereby increasing the clamping force on the screw 1 and further preventing the screw 1 from rotating.

[0033] The first clamp body 21 includes a first clamp block 211 . The side of the first clamp block 211 is provided with at least two first locking holes 212 . The two first locking holes 212 are symmetrically arranged about the axis of the threaded rib 5 .

Specifically, when the two are connected together, the lead screw 1 is clamped, that is, the locking bolt 23 passes through the first locking hole 212 to the second locking hole 222, and then the first clamping block 211 and the second clamping block 221 can be connected by connecting the nut and the locking bolt 23. The threaded rib 5 is located on the inner wall of the circular hole formed by the first clamping block 211 and the second clamping block 221, so as to be combined with the thread line or thread groove of the lead screw 1.

For the convenience of connection, an internal thread can be set on the inner wall of the second locking hole 222, that is, at this time, the locking bolt 23 passes through the first locking hole 212 and is connected with the internal thread in the second locking hole 222, thereby connecting the first clamp 211 and the second clamp 221 into a whole. In other embodiments, an internal thread can also be set on the inner wall of the first locking hole 212, and the second locking hole 222 is a through hole. At this time, the locking bolt 23 passes through the second locking hole 222 and extends to the position of the first locking hole 212 and is connected with the internal thread of the first locking hole 212, thereby realizing the connection between the first clamp 211 and the second clamp 221 to hold the screw 1 tightly.
