[0024] To make the above-mentioned objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation modes.

[0025] As Figure 1 shown, this embodiment provides a multi-directional adjustment structure 100 for a head mold, including:

[0026] A fixed bracket 1, a horizontal first fixed shaft 3 is fixedly arranged at the top of the fixed bracket 1, and both ends of the first fixed shaft 3 extend out of the fixed bracket 1 respectively;

[0027] A rotating bracket 2, the rotating bracket 2 straddles the top of the fixed bracket 1, and both ends of the first fixed shaft 3 are respectively rotatably connected to the rotating bracket 2. A first indexing pin 9 is arranged on the rotating bracket 2, and the free end of the first indexing pin 9 can be in close contact with the fixed bracket 1 to limit the rotation of the rotating bracket 2 relative to the fixed bracket 1. A second fixed shaft perpendicular to the first fixed shaft 3 is fixedly arranged at the top end of the rotating bracket 2;

[0028] A rotating base 6, the rotating base 6 is rotationally matched with the second fixed shaft through a first bearing. The inner ring of the first bearing is fixedly connected to the second fixed shaft, and the outer ring of the first bearing is fixedly connected to the rotating base 6. A head mold 7 is fixedly arranged on the rotating base 6;

[0029] A second indexing pin 10 arranged on the top surface of the fixed bracket 1, and the free end of the second indexing pin 10 can be in close contact with the bottom surface of the rotating base 6 to limit the rotation of the rotating base 6 relative to the rotating bracket 2.

[0030] The multi-directional adjustment structure 100 of the head mold in this embodiment can adjust the position and multiple directions of the head mold 7 by rotating the rotating bracket 2 relative to the fixed bracket 1 and / or rotating the rotating base 6, and can simulate the scenario of wearing a headgear when the human body is in a moving state, thereby facilitating the improvement of the reliability of the detection results of protective equipment.

[0031] The setting of the first indexing pin 9 can limit the rotation of the rotating bracket 2 relative to the fixed bracket 1. When it is necessary to rotate the rotating bracket 2 relative to the fixed bracket 1, only the first indexing pin 9 needs to be loosened so that the first indexing pin 9 is not in close contact with the fixed bracket 1, and then the rotating bracket 2 can be manually rotated relative to the fixed bracket 1, which is convenient to use.

[0032] The setting of the second indexing pin 10 can limit the rotation of the rotating base 6 relative to the rotating bracket 2. When it is necessary to rotate the rotating base 6, only the second indexing pin 10 needs to be loosened so that the second indexing pin 10 is not in close contact with the rotating base 6, and then the rotating base 6 can be manually rotated, which is convenient to use.

[0033] It should be noted that even if the rotating bracket 2 rotates relative to the fixed bracket 1, the second fixed axis is always perpendicular to the first fixed axis 3.

[0034] In an alternative embodiment of this embodiment, preferably, an arc-shaped groove 4 is provided on the rotating bracket 2, and a horizontal fixing rod 5 is provided on the fixed bracket 1. The fixing rod 5 is located in the arc-shaped groove 4 and is slidably engaged with the arc-shaped groove 4; the setting of the arc-shaped groove 4 limits the range of rotation of the rotating bracket 2 relative to the fixed bracket 1. When the fixing rod 5 abuts against the end of the arc-shaped groove 4, the rotation of the rotating bracket 2 relative to the fixed bracket 1 can be limited.

[0035] In an alternative embodiment of this embodiment, preferably, the central angle of the arc-shaped groove 4 in the multi-directional adjustment structure of the head mold in this embodiment is 180°. When the fixing rod 5 is located at the middle position of the arc-shaped groove 4, the head mold 7 is exactly in the vertically upward state. Therefore, when the rotating bracket 2 rotates relative to the fixed bracket 1, the rotating bracket 2 drives the head mold 7 to be able to rotate in two directions (left and right) (taking Figure 1 the perspective as the standard) with a maximum angle of 90°; it should be noted that in actual applications, the size of the central angle of the arc-shaped groove 4 can be adjusted adaptively according to actual needs.

[0036] In an alternative embodiment of this embodiment, preferably, both ends of the first fixed axis 3 are rotatably connected to the rotating bracket 2 through second bearings. The setting of the second bearings makes the relative rotation between the rotating bracket 2 and the first fixed axis 3 relatively flexible and can reduce the wear when the rotating bracket 2 rotates relative to the first fixed axis 3.

[0037] In an alternative embodiment of the present embodiment, preferably, two handles 8 are provided on the side wall of the rotating base 6. The provision of the handles 8 facilitates the staff to rotate the rotating base 6. It should be noted that the specific number of the handles 8 can be adjusted adaptively according to actual needs.

[0038] In an alternative embodiment of the present embodiment, preferably, the first indexing pin 9 is a reset type indexing pin, and the second indexing pin 10 is a handle knob plunger L-type indexing pin. The reset type indexing pin and the handle knob plunger L-type indexing pin are both prior arts, and the specific structures and working principles of the reset type indexing pin and the handle knob plunger L-type indexing pin will not be elaborated in this embodiment.

[0039] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "top", "bottom", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0040] Specific examples are used in the present invention to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present invention.
