DETAILED DESCRIPTION

[0029] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-Figure 12 The present invention provides a technical solution: a cold-drawn special-shaped steel with a shock-absorbing structure, comprising a cold-drawn special-shaped steel body 1, both ends of the cold-drawn special-shaped steel body 1 are sleeved with mounting sleeves 2, one end of the sealing plate 3 is fixed with a sealing plate 3, the mounting sleeve 2 is a "convex"-shaped frame, the contour of the mounting sleeve 2 matches the shape of the cold-drawn special-shaped steel body 1, the height of the mounting sleeve 2 is equal to the height of the cold-drawn special-shaped steel body 1, after the mounting sleeve 2 is sleeved on the cold-drawn special-shaped steel body 1, the sealing plate 3 is against the cold-drawn special-shaped steel body 1, a bottom plate 4 is fixed to the bottom end of the mounting sleeve 2, a buckle groove is provided on the bottom surface of the bottom plate 4, a rubber pad 5 is fixed on the surface of the buckle groove, a baffle 6 is fixed to one end of the bottom plate 4, after the two cold-drawn special-shaped steel bodies 1 are stacked, the bottom plate 4 at the end of one cold-drawn special-shaped steel body 1 is buckled on the mounting sleeve 2 at the end of the other cold-drawn special-shaped steel body 1, the rubber pad 5 is clamped between the bottom plate 4 and the mounting sleeve 2 to generate elastic deformation, the width of the buckle groove is equal to the width of the bottom plate 4, and the baffle 6 blocks one end of the bottom plate 4.

[0031] During use, after the mounting sleeves 2 are sleeved on both ends of the cold-drawn special-shaped steel body 1, when multiple cold-drawn special-shaped steel bodies 1 are stacked, the mounting sleeves 2 and the bottom plate 4 cooperate between two adjacent cold-drawn special-shaped steel bodies 1 to prevent the stacked cold-drawn special-shaped steel bodies 1 from being skewed, that is, the bottom plate 4 at the end of an upper cold-drawn special-shaped steel body 1 is buckled on the mounting sleeve 2 at the end of a lower cold-drawn special-shaped steel body 1, and the rubber pad 5 is clamped between the mounting sleeve 2 and the bottom plate 4 to play a shock-absorbing role, and after the mounting sleeve 2 is braked at the end of the cold-drawn special-shaped steel body 1, the baffle 6 blocks one side of the cold-drawn special-shaped steel body 1, so the stacked cold-drawn special-shaped steel bodies 1 will not shift horizontally, thereby ensuring that multiple cold-drawn special-shaped steel bodies 1 are stacked neatly.

[0032] The two parallel side plates of the installation sleeve 2 are provided with a reserved groove 8 and a mounting groove 7. The two reserved grooves 8 are opposite to each other, and the reserved groove 8 and the mounting groove 7 are symmetrically distributed about the side plate of the installation sleeve 2. The mounting groove 7 is a round groove, and the reserved groove 8 is a square groove. Two sockets 9 are provided on the surface of the installation groove 7. The sockets 9 connect the installation groove 7 and the reserved groove 8. A clamping block 11 is inserted into the inside of the socket 9. A turntable 13 is connected to the inside of the installation groove 7 for rotation. The turntable 13 squeezes the clamping block 11 through the socket 9 and clamps the cold-drawn special-shaped steel body 1, which is used to limit the installation sleeve 2 on the cold-drawn special-shaped steel body 1; an elastic band 10 is fixed on the surface of the reserved groove 8, and one end of the clamping block 11 is fixed to the elastic band 10. The surface of the clamping block 11 is greater than the depth of the socket 9. When the turntable 13 squeezes the clamping block 11 to clamp the cold-drawn special-shaped steel body 1, the clamping block 11 tensions the elastic band 10 to produce elastic deformation, thereby increasing the friction between the clamping block 11 and the cold-drawn special-shaped steel body 1; a limiting shaft 12 is fixed on the surface of the mounting groove 7, the turntable 13 is a circular ring plate, and the inner ring mouth of the turntable 13 is sleeved on the limiting shaft 12. A notch 14 is provided on the surface of the turntable 13. The notch 14 is a "U"-shaped groove. There are two notches 14, and the two notches 14 are symmetrically distributed about the inner ring mouth of the turntable 13. When the notch 14 corresponds to the clamping block 11, the elastic band 10 is in an initial state, and the clamping block 11 is retracted into the socket 9.

[0033] When in use, after the installation sleeve 2 is sleeved on the cold-drawn special-shaped steel body 1, the turntable 13 is turned to rotate, and the clamping block 11 is pushed into the socket 9 until the rotating turntable 13 covers the socket 9. At this time, the clamping block 11 is squeezed by the turntable 13, and the clamping block 11 tensions the elastic band 10 to produce elastic deformation. The elastic band 10 is clamped between the clamping block 11 and the cold-drawn special-shaped steel body 1, thereby realizing the anti-slip limit position after the installation sleeve 2 is sleeved on the cold-drawn special-shaped steel body 1; when the installation sleeve 2 needs to be removed, the turntable 13 is rotated so that the notch 14 and the socket 9 are opposite. At this time, the elastic band 10 rebounds and pulls the clamping block 11 into the socket 9, that is, the clamping block 11 no longer clamps the cold-drawn special-shaped steel body 1, and the installation sleeve 2 can be pulled out of the cold-drawn special-shaped steel body 1.

[0034] A baffle 15 is fixed to one end of the limiting shaft 12, and the plate length of the baffle 15 is larger than the inner ring diameter of the turntable 13. A screw hole 18 is provided on the surface of the baffle 15, and a clamping screw 19 is screwed inside the screw hole 18. A screw handle 20 is fixed to one end of the clamping screw 19, and the clamping screw 19 is against one side of the turntable 13 to brake the turntable 13. An embedding groove 16 is provided on the surface of the turntable 13, and the embedding groove 16 is an annular groove. A rubber ring 17 is fixed inside the embedding groove 16, and the rubber ring 17 is an annular plate structure. The thickness of the rubber ring 17 is greater than the depth of the embedding groove 16. After the clamping screw 19 is locked, the rubber ring 17 is clamped to increase the friction of the clamping screw 19 braking the turntable 13.

[0035] The baffle 15 is installed in order to block the turntable 13 through the baffle 15 to prevent the turntable 13 from falling off the mounting groove 7. After the turntable 13 is rotated to the specified position, the screw handle 20 is squeezed by hand to drive the clamping screw 19 to rotate and advance until one end of the clamping screw 19 passes through the screw hole 18 and tightly clamps the rubber ring 17. At this time, the turntable 13 is tightly pressed against the mounting groove 7 to achieve braking.

[0036] When used as a whole, first, the installation sleeve 2 is sleeved on both ends of the cold-drawn special-shaped steel body 1. The shape of the installation sleeve 2 matches the cold-drawn special-shaped steel body 1 to ensure stable fitting. The side panel of the installation sleeve 2 is provided with a reserved groove 8 and an installation groove 7, and the reserved groove 8 and the installation groove 7 are symmetrically distributed about the side panel of the installation sleeve 2. An elastic band 10 is fixed in the reserved groove 8, and one end of the elastic band 10 is connected to the clamping block 11. A turntable 13 is rotatably connected inside the installation groove 7, and the inner ring of the turntable 13 is sleeved on the limit shaft 12. There is a notch 14 on the surface of the turntable 13 for subsequent release of the clamping block 11. The turntable 13 is turned to rotate, and the clamping block 11 is pushed into the installation groove 7 through the socket 9. The turntable 13 continues to rotate until it covers the socket 9. At this time, the turntable 13 squeezes the clamping block 11, and the clamping block 11 tensions the elastic band 10, causing the elastic band 10 to produce elastic deformation and fit tightly against the cold-drawn special-shaped steel body 1, thereby achieving the fixation of the installation sleeve 2 on the cold-drawn special-shaped steel body 1.

[0037] After the mounting sleeve 2 is fixed, the rubber pad 5 on the bottom plate 4 at the bottom thereof plays a shock-absorbing role when the cold-drawn special-shaped steel bodies 1 are stacked. When the bottom plate 4 of one cold-drawn special-shaped steel body 1 is buckled on the mounting sleeve 2 of another cold-drawn special-shaped steel body 1, the rubber pad 5 is elastically deformed due to being clamped between the mounting sleeve 2 and the bottom plate 4, absorbing the impact force during stacking. The buckle groove design of the bottom plate 4 and the blocking effect of the baffle 6 ensure that the stacked cold-drawn special-shaped steel bodies 1 will not deflect or shift, and maintain the neatness of the stacking.

[0038] After the mounting sleeve 2 is fixed, the rubber pad 5 on the bottom plate 4 at the bottom thereof plays a shock-absorbing role when the cold-drawn special-shaped steel bodies 1 are stacked. When the bottom plate 4 of one cold-drawn special-shaped steel body 1 is buckled on the mounting sleeve 2 of another cold-drawn special-shaped steel body 1, the rubber pad 5 is elastically deformed due to being clamped between the mounting sleeve 2 and the bottom plate 4, absorbing the impact force during stacking. The buckle groove design of the bottom plate 4 and the blocking effect of the baffle 6 ensure that the stacked cold-drawn special-shaped steel bodies 1 will not deflect or shift, and maintain the neatness of the stacking.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
