[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. In this utility model, through the arrangement of a support column assembly and a hydraulic rod, a first elastic support ball is fixedly connected to the upper end of the support column assembly, and four L-shaped support arms are rotatably connected in a circular array on the outer upper end of the support column assembly. When a helmet is placed on the support column assembly, the four L-shaped support arms are inserted into the interior of the helmet, and the four second elastic support balls provide multi-point support for the helmet. At the same time, the first elastic support ball on the support column assembly supports the middle part of the upper end of the helmet, ensuring that the helmet remains stable after placement.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] See also Figure 1-4 , the utility model provides an embodiment: an automatic locking device for helmet production, comprising a table 1, a control device 101 is fixedly provided on the upper end of the table 1, a circular connecting column 102 is fixedly provided on the middle part of the upper end of the table 1, and the upper end of the circular connecting column 102 is rotatably connected to the support column assembly 2, and the upper end of the support column assembly 2 is fixedly connected to a first elastic support ball 202, and the upper end of the outer upper end of the support column assembly 2 is rotatably connected to four L-shaped support arms 3 in a circular array, and the upper ends of the four L-shaped support arms 3 are fixedly connected to a second elastic support ball 301, and a pneumatic rod 4 is connected between the middle part of the lower end of the L-shaped support arm 3 and the support column assembly 2, and the rear end of the upper end face of the support column assembly 2 is fixedly connected to an L-shaped support frame 5, and the upper end of the L-shaped support frame 5 is fixedly connected to a hydraulic rod 6, and the telescopic end of the hydraulic rod 6 extends through the L-shaped support frame 5 to the lower end and is fixedly connected to a pressure sensor 601, and the lower end of the pressure sensor 601 is fixedly connected to an elastic downward pressure ball 602.

[0024] Furthermore, the upper end of the circular connecting column 102 is fixedly connected to the fixed shaft 103 , and the lower end of the inner portion of the supporting column assembly 2 is provided with a circular slot 201 .

[0025] Furthermore, the circular connecting column 102 and the support column assembly 2 are rotatably connected by inserting the fixed shaft 103 into the circular slot 201, so that the support column assembly 2 can rotate at the upper end of the circular connecting column 102. When the helmet is placed on the upper end of the support column assembly 2, the four L-shaped support arms 3 are inserted into the interior of the helmet, and the four second elastic support balls 301 provide multi-point support for the helmet. The first elastic support ball 202 on the support column assembly 2 supports the middle part of the upper end of the interior of the helmet, so that the helmet remains stable after being placed.

[0026] Furthermore, four trapezoidal slots 203 are provided in a circular array at the middle upper end of the side end surface of the support column assembly 2 .

[0027] Furthermore, the lower end of the L-shaped support arm 3 is inserted into the trapezoidal slot 203 and is rotatably connected via the first rotating shaft 302 , so that the L-shaped support arm 3 can deflect downward when pressed.

[0028] Furthermore, the upper end of the pneumatic rod 4 is rotatably connected to the middle portion of the lower end of the L-shaped support arm 3 via a second rotating shaft 401 .

[0029] Furthermore, the lower end of the pneumatic rod 4 is rotatably connected to the support column assembly 2 via the third rotating shaft 402. The pneumatic rod 4 supports the L-shaped support arm 3 and the support column assembly 2. When a helmet is placed on the upper end of the support column assembly 2, the control device 101 controls the telescopic end of the hydraulic rod 6 to extend downward. The elastic downward-pressing ball 602 on the pressure sensor 601 at the lower end of the hydraulic rod 6 then descends and presses down on the upper end of the helmet. When the elastic downward-pressing ball 602 contacts the helmet and begins to press downward, the helmet is subjected to downward pressure, which in turn causes the L-shaped support arm 3 supporting the helmet to be subjected to a downward force. Because the lower end of the L-shaped support arm 3 is rotatably connected to the upper end of the pneumatic rod 4 via the second rotating shaft 401, and the lower end of the pneumatic rod 4 is rotatably connected to the support column assembly 2 via the third rotating shaft 402, the L-shaped support arm 3 can deflect downward when subjected to downward pressure. At the same time, the pneumatic rod 4 provides supporting force. As the hydraulic rod 6 continues to press downward, the helmet is further pressed against the support column assembly 2 and the L-shaped support arm 3, achieving automatic locking of the helmet.

[0030] Working principle: When in use, at work, first place the helmet on the upper end of the support column assembly 2. The support column assembly 2 is rotatably connected to the circular connecting column 102 via a fixed shaft 103, which can adapt to helmets placed at different angles. When the helmet is placed on the support column assembly 2, the four L-shaped support arms 3 are inserted into the interior of the helmet. The four second elastic support balls 301 provide multi-point support for the helmet. At the same time, the first elastic support ball 202 on the support column assembly 2 supports the middle part of the upper end of the helmet, so that the helmet remains stable after placement. Then, the control device 101 controls the telescopic end of the hydraulic rod 6 to extend downward. The elastic downward pressure ball 602 on the pressure sensor 601 at the lower end of the hydraulic rod 6 then descends and presses down on the upper end of the helmet. When the elastic downward pressure ball 602 contacts the helmet and begins to press down, the helmet is subjected to downward pressure, so that the L-shaped support arms 3 supporting the helmet are subjected to a downward force. Since the lower end of the L-shaped support arm 3 is rotatably connected to the upper end of the pneumatic rod 4 via the second rotating shaft 401, and the lower end of the pneumatic rod 4 is rotatably connected to the support column assembly 2 via the third rotating shaft 402, the L-shaped support arm 3 can deflect downward when subjected to downward pressure, while the pneumatic rod 4 provides supporting force. As the hydraulic rod 6 continues to press downward, the helmet is further pressed against the support column assembly 2 and the L-shaped support arm 3, achieving automatic locking of the helmet. At this time, the pneumatic rod 4 and the hydraulic rod 6 jointly maintain the stable position of the helmet, ensuring that the helmet will not move or fall off during the assembly process. When it is necessary to remove the helmet, the control device 101 only needs to control the telescopic end of the hydraulic rod 6 to retract upward, the elastic downward pressure ball 602 rises, and the L-shaped support arm 3 returns to its original position under the action of the pneumatic rod 4, and the helmet can be easily removed.

[0031] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
