Technical Field

[0001] The utility model belongs to the technical field of new steel castings, and more specifically, particularly relates to an anti-collision steel casting provided with a connection structure. Background Art

[0002] Steel castings refer to parts made of cast steel, which have similar properties to cast iron, but better strength than cast iron. Steel castings are needed in almost all industrial sectors, and are particularly widely used in ships and vehicles, construction machinery, engineering machinery, power station equipment, mining machinery and metallurgical equipment, aviation and aerospace equipment, oil wells and chemical equipment, etc. As for the application of steel castings in various industrial sectors, the situation may vary greatly due to different specific conditions in different countries.

[0003] Today's anti-collision cast steel parts are used as highway guardrail brackets. When installing highway guardrails, the guardrail mounting hole is often integrated with the base, and the guardrail is generally long. As a result, during the installation process, the guardrail needs to be passed through the mounting hole of the bracket before the entire guardrail can be installed on the side of the road. The installation efficiency is slow, and when the railing needs to be replaced, the guardrail bracket needs to be removed as a whole, which is inconvenient for subsequent maintenance.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an anti-collision cast steel part with a connecting structure is provided, in order to achieve a more practical purpose. Utility Model Content

[0026] Furthermore, the spring clamping member 7 includes a sleeve 11, which is slidably connected to the slide groove 6, and a slide rod 18 is rotatably connected inside the sleeve 11. A knob 12 is fixedly installed at one end of the slide rod 18, and a clamping block 15 is fixedly connected to the other end of the slide rod 18, and the knob 12 is located on the outside of the slide groove 6 and inside the protective cap 9.

[0027] Furthermore, the bottom end of the slide groove 6 is fixedly connected to a limit block 14 , and the limit block 14 is penetrated by a slide rod 18 . The slide rod 18 is located at one end of the limit block 14 , and blocks 15 are symmetrically connected on both sides, and a pair of blocks 15 are located below the limit block 14 .

[0028] Furthermore, a spring 13 is connected between the sleeve 11 and the limit block 14. The spring 13 is sleeved on the outside of the slide bar 18. By providing the spring 13, the slide bar 18 can obtain the force of the spring 13 and is more stable.

[0029] Furthermore, a circular groove 19 is formed through the center of the locking block 10, and rectangular grooves 20 are formed through the left and right sides of the circular groove 19. The bottom end of the locking block 10 is located at the front and rear sides of the circular groove 19 and has locking grooves 17. By providing the circular groove 19 and the rectangular groove 20, the sliding rod 18 and the locking block 15 can pass through the locking block 10 and be firmly engaged in the locking groove 17.

[0030] Furthermore, a mounting groove 16 is provided on one side of the base 1 , and the threaded hole 2 is located below the mounting groove 16 . By providing the mounting groove 16 , the threaded hole 2 can be more easily fixed in place by screws.

[0031] The working principle of this embodiment:

[0032] When the utility model is used as a mounting bracket for installing a highway guardrail, the base 1 is first placed in a pre-installed position, and the screw is fixed in the threaded hole 2 through the mounting groove 16. After the base 1 is fixed, the guardrail is placed in the first semicircular block 3. After adjusting the position, the second semicircular block 5 is connected to the first semicircular block 3 through the hinge 4 to form a whole. Then, the knob 12 is pressed downward, and the knob 12 drives the sleeve 11 to move downward in the slide groove 6, and the slide bar 18 moves downward. The block 15 starts to move downward from the bottom of the limit block 14, and the slide bar 18 and the block 15 are inserted into the engaging block 10 through the circular groove 19 and the rectangular groove 20. The knob 12 is rotated to make the slide bar 18 drive the block 15 to rotate, so that the block 15 can be engaged in the slot 17. The sleeve 11 is connected to the spring 13, so that the entire slide rod 18 is affected by the tension of the spring 13 and can be tightly fixed in the slot 17. Then the protective cap 9 is threadedly connected to the convex ring 8 to protect the knob 12 from being disturbed by external factors. When the guardrail needs to be disassembled, the protective cap 9 is rotated open and the knob 12 is rotated again to disengage the block 15 from the slot 17. The resilience of the spring 13 makes the sleeve 11 move upward on the slide groove 6, driving the slide rod 18 to move upward, so that the block 15 returns to the groove position of the limit block 14 and engages, and the first semicircular block 3 and the second semicircular block 5 are separated. This structure not only ensures the convenience of connection, but also has strong stability. It is not only convenient for the installation of highway guardrails, but also makes subsequent maintenance more convenient.
