Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0023] Referring to the attached Figure 1 - attached Figure 6 , the present utility model provides a freely deformable road guardrail, including a box body 1, two symmetrically distributed movable plates 2 are arranged inside the box body 1, and adjusting members for moving the movable plates 2 are arranged on the outer sides of both ends of the box body 1;

[0024] The adjusting member is a fixed shaft 3 arranged inside one end of the box body 1, and dial plates 4 are installed on both sides of the fixed shaft 3. The front and rear ends of the fixed shaft 3 penetrate through the box body 1 and are movably connected to the box body 1 through bearings. Cam 5 is sleeved on the outer sides of the front and rear ends of the fixed shaft 3. Touch plates 6 are arranged at the bottoms of the two cams 5. The bottoms of the two touch plates 6 are provided with the same movable frame 7. The movable frame 7 is sleeved on the outer side of the bottom end of the box body 1, and a positioning plate 8 is installed at the top of the movable frame 7. A return member for resetting the movable frame 7 is arranged at the bottom of each touch plate 6.

[0025] When adjusting the movable plate 2 inside the box body 1, since the front and rear ends of the fixed shaft 3 are both provided with knobs 16, and the knobs 16 are arranged on the side of the cam 5 away from the box body 1, it enables the staff to rotate the knob 16 to drive the two dial plates 4 and the two cams 5 on the fixed shaft 3 to rotate. When the cam 5 and the dial plate 4 rotate downward along with the fixed shaft 3, the cam 5 first contacts the touch plate 6 and squeezes the touch plate 6 to move downward. The touch plate 6 then drives the positioning plate 8 on the movable frame 7 to move downward, while the dial plate 4 synchronously rotates to the position of the movable plate 2;

[0026] Among them, as Figures 2 - 4 shown, since a plurality of positioning grooves 19 are formed at intervals at the bottom of the movable plate 2, and the top end of the positioning plate 8 penetrates through the box body 1 and extends into one of the positioning grooves 19, a clamping member is formed on one side of the top of the movable plate 2 corresponding to the clamping groove 12. The clamping member includes two clamping grooves 12 mirror-symmetrically distributed on the top of the movable plate 2, so that the dial plate 4 will rotate into one of the clamping grooves 12 on the movable plate 2. At this time, the positioning plate 8 is separated from the positioning groove 19 on the movable plate 2. In this way, the movable plate 2 can be driven to move outwards by the contact between the dial plate 4 and the clamping groove 12, achieving the effect of adjusting the extension length of the movable plate 2;

[0027] In order to ensure the stability of the movable plate 2 after adjustment, it is necessary to limit the movable plate 2. As Figures 2 - 4 shown, the resilient member includes a support plate 9 provided at the bottom of the touch plate 6. The support plate 9 is sleeved outside the movable frame 7, and the support plate 9 is installed on one side of the box body 1 corresponding to the touch plate 6. Both top ends of the support plate 9 are provided with telescopic rods 10 for connecting the touch plate 6, and a spring 11 is sleeved outside the top end of the telescopic rod 10. Since the touch plate 6 is supported by the spring 11 on the telescopic rod 10, when the cam 5 drives the movable plate 2 to move outwards with the dial plate 4 on the fixed shaft 3, the cam 5 is synchronously separated from the touch plate 6. Thus, the touch plate 6 drives the positioning plate 8 on the movable frame 7 to move upwards by the resilience of the spring 11, and the positioning plate 8 is inserted into the corresponding positioning groove 19. The adjusted movable plate 2 is limited by the engagement of the positioning plate 8 and the positioning groove 19 to ensure the stability of the movable plate 2 after adjustment. And through the linkage cooperation of the dial plate 4 and the cam 5, the adjustable locking of the movable plate 2 is realized, thereby improving the convenience of adjusting the movable plate 2.

[0028] At the same time, in order to ensure the stability of the movable plate 2 after it moves outwards, it is necessary to support one end of the movable plate 2 away from the box body 1. As Figure 1 , Figure 2 and Figure 4 shown, material openings 13 are formed at both ends of the box body 1. One ends of the two movable plates 2 away from each other extend outside the material openings 13, and an installation groove 14 is formed at the bottom of the end of the movable plate 2 away from the box body 1. A support leg 15 is provided at the bottom of the installation groove 14. The top end of the support leg 15 extends into the installation groove 14, and the outer part of the top end of the support leg 15 is threadedly connected to the inner wall of the installation groove 14. When the movable plate 2 is adjusted to move outwards, the movable plate 2 moves out of the box body 1 through the material opening 13, and then the support leg 15 supports the movable plate 2, thereby ensuring the stability of the movable plate 2. And the support leg 15 is threadedly connected to the movable plate 2. In this way, the support leg 15 can be rotated to be separated from the movable plate 2, and then the support leg 15 can be conveniently stored and folded for transportation.

[0029] To ensure the stability of the movable plate 2 during adjustment, it is necessary to limit the movement of the movable plate 2. Therefore, two positioning members for respectively limiting the two movable plates 2 are provided inside the box body 1; each group of positioning members includes two sliding grooves 17, which are respectively opened on the inner walls of the front and rear sides of the box body 1, and the movable plate 2 is arranged between the two sliding grooves 17. A slider 18 for connecting the movable plate 2 is provided inside one end of the sliding groove 17 away from the box body 1. In this way, the movable plate 2 can be limited by the engagement of the slider 18 and the sliding groove 17, thereby preventing the movable plate 2 from detaching from the box body 1 and ensuring the adjustment stability of the movable plate 2.

[0030] Finally, the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
