[0016] The utility model will be described in detail below in combination with the drawings and specific embodiment:

[0017] In the description of the utility model, it is understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, so it cannot be understood as a limitation on the utility model.

[0018] In order to make the purpose, technical scheme and advantages of the utility model clearer and more apparent, the utility model will be further described in detail below in combination with the drawings and examples.

[0019] As Figures 1 to 3 The utility model provides a kind of structure diagram of tow device of movable security check platform provided in the embodiment of the utility model, including fixed in the tow seat 3 of movable security check platform base 1 side face, the cavity of tow seat 3 is placed with tow bar 4, tow bar 4 can swing in the first gap of tow seat 3 top, the bottom of tow bar 4 is equipped with fixed shaft 305, and fixed shaft 305 slides in the second gap 304 of the side wall of tow seat.

[0020] In the embodiment of the utility model, through the tow seat 3 of movable security check platform base 1 side face, the cavity of tow seat 3 is placed with tow bar 4, tow bar 4 can swing in the first gap of tow seat 3 top, the bottom of tow bar 4 is equipped with fixed shaft 305, and fixed shaft 305 slides in the second gap 304 of the side wall of tow seat, realize the folding of tow bar 4 in tow seat, reduce the space occupied by tow bar 4 when not using, and the whole device is not additionally provided with locking mechanism or reset mechanism, simple structure, low cost, stable function, easy to popularize in large area.

[0021] Based on the above embodiment, in one example of the utility model, the cavity of the tow seat 3 is rectangular, the first gap 302 of the top of the tow seat 3 is provided with a limiting table 301, and the distance between the limiting table 301 and the bottom of the cavity is greater than the diameter of the tow bar or the maximum width of the tow bar. The advantage of this arrangement is that when the tow bar 4 is inserted into the cavity, the tow bar 4 will not automatically rotate. The reason is that the distance between the limiting table 301 and the bottom of the cavity is greater than the diameter of the tow bar or the maximum width of the tow bar, so that the tendency of the tow bar 4 to rotate is limited by the limiting table 301.

[0022] Based on the above embodiment, in another example of the utility model, the fixed shaft 305 is provided with two, and the fixed shaft 305 is symmetrically arranged on the bottom side of the tow bar 4.

[0023] Based on the above embodiment, in another example of the utility model, the fixed shaft 305 is a threaded shaft, and the limiting boss 306 is a nut.

[0024] Based on the above embodiment, in another example of the utility model, the fixed shaft 305 is an optical shaft, and the limiting boss 306 is a ring-shaped sleeve that fixes the end of the optical shaft with a pin.

[0025] Preferably, the maximum outer diameter of the annular sleeve or the nut is greater than the width of the second gap 304.

[0026] Based on the above embodiment, in another example of the utility model, the top limiting portion 303 is located above the limiting platform 301, and the height of the top limiting portion 303 from the limiting platform 301 is greater than the diameter of the dragging rod 4 or the maximum width of the dragging rod. Such arrangement can ensure that when the dragging rod 4 slides to the top of the second gap 304, the fixed shaft 305 is tangent to the sidewall of the second gap 304, and at the same time, the height of the top limiting portion 303 from the limiting platform 301 is greater than the diameter of the dragging rod 4 or the maximum width of the dragging rod. At this time, since the fixed shaft 305 is located at the bottom side of the dragging rod 304, it can be rotated away from the base 1, thereby realizing dragging of the dragging rod in a multi-angle range.

[0027] Based on the above embodiment, in another example of the utility model, the bottom limiting portion 307 is located below the limiting platform 301, and the distance between the bottom limiting portion 307 and the limiting platform 301 is greater than the diameter of the dragging rod 4 or the maximum width of the dragging rod.

[0028] Based on the above embodiment, in another example of the utility model, the bottom of the dragging rod 4 is spherical or arc-shaped, which facilitates sliding of the dragging rod 4 in the cavity and prevents jamming.

[0029] Based on the above embodiment, in another example of the utility model, the dragging seat 3 is welded or threadedly connected to the side of the movable security platform base 1.
