[0024] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0025] Reference Figure 1-4 , a movable protection device for a flatbed tow truck, comprising two sets of protection mechanisms connected by a connecting plate 4, the protection mechanism comprising a protection frame 1, a fixing plate 1 2, a fixing plate 2 3, a protection plate 5 and a slide seat 7, the protection frame 1 is divided into two upper and lower distributions, and connected by the fixing plate 1 2 and the fixing plate 2 3, the two ends of the protection frame 1 are integrally provided with an end portion 101 with an increased width, the slide seat 7 is divided into two, and is respectively fixed to the upper and lower ends of the protection plate 5 by a fixing column 6, and the slide seat 7 slides in a slide groove provided on the protection frame 1, the width of the slide groove at the end portion 101 is greater than the width of the slide groove in the middle of the protection frame 1, the width of the slide seat 7 is adapted to the inner width of the slide groove in the middle of the protection frame 1, and the length of the slide seat 7 is adapted to the inner width of the slide groove at the end portion 101;

[0026] When the vehicle accessories are needed, the spring pin 8 can be squeezed to disengage the spring pin 8 from the positioning hole 501, and then the protective plate 5 can be pushed to move the slide seat 7 to the end portion 101. Since the inner width of the slide groove at the end portion 101 is widened, the slide seat 7 can be rotated at the end portion 101, and the protective plate 5 can be rotated to open the protective plate 5 to take the vehicle accessories. After taking, the protective plate 5 is rotated again to Figure 1 In the state shown, the spring pin 8 is pressed to push the protective plate 5 to the position where the positioning hole 501 and the spring pin 8 correspond. The spring pin 8 is stretched and inserted into the positioning hole 501 to restrict the positioning hole 501.

[0027] There are three fixing plates 2, which are respectively arranged on both sides and the middle of the protective frame 1, and there are two fixing plates 2 3, which are staggered between the three groups of fixing plates 2; the cooperation of fixing plates 1 2 and fixing plates 2 3 can make the connection between the two protective frames 1 more stable, and fixing plates 2 3 are installed between the two protective frames 1. When the protective plate 5 is in a closed state between the two protective frames 1, the spring pin 8 passes through the positioning hole 501, and the end face of the protective plate 5 can be attached to the fixing plates 2 3. The fixing plates 2 3 can strengthen the support for the side of the protective plate 5, thereby ensuring the protective performance of the protective device.

[0028] The fixed column 6 slides in contact with the end of the slide groove of the protective frame 1, ensuring that the protective plate 5 can move normally and increasing the stability of the device. A spring pin 8 is installed on a group of fixed plates 2 located in the middle, and the spring pin 8 includes a fixed cylinder, a movable cylinder and a spring. The movable cylinder is elastically connected to the fixed cylinder through a spring, and the movable cylinder is slidably arranged inside the fixed cylinder. A positioning hole 501 is also provided on the protective plate 5 for the spring pin 8 to pass through. After the protective plate 5 slides to a predetermined position, the spring pin 8 passes through the positioning hole 501, which can limit the protective plate 5 and prevent the protective plate 5 from moving again.

[0029] Two sides of the slide 7 are arc-shaped structures, and the other two sides are planar structures. The planar structure of the slide 7 can slide along the inner side of the slide groove of the protective frame 1; when the slide 7 is in the middle of the protective frame 1, it will be restricted and can only slide. When the slide 7 moves to the end portion 101, the internal space of the slide groove at its position increases, and the slide 7 can rotate. At this time, the protective plate 5 can be rotated to achieve opening and closing.

[0030] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
