Description

Technical Field

[0001] The utility model relates to the technical field of special-shaped steel, in particular to a high-precision special-shaped steel. Background Technique

[0002] Special-shaped steel is the abbreviation of complex and special-shaped cross-section steel, which belongs to a kind of section steel and is different from the name of simple cross-section steel. According to different processes, it can be divided into hot-rolled special-shaped steel, cold-drawn special-shaped steel, cold-bent special-shaped steel, welded special-shaped steel, etc. Usually, special-shaped steel specifically refers to hot-rolled special-shaped steel. Hot-rolled special-shaped steel is different from square steel, round steel, flat steel and common-shaped hot-rolled section steel. Among them, cold-drawn section steel is steel with various cross-sectional shapes and sizes processed by cold drawing, and cold-drawn section steel is also called cold-drawn steel.

[0003] Chinese Patent with publication number CN215411337U discloses a high-precision cold-drawn detachable special-shaped steel, including a special-shaped steel body. The cross-section of the special-shaped steel body is rectangular. Splicing dovetail grooves are provided on both sides of the special-shaped steel body. The width of the splicing dovetail grooves gradually widens from the opening to both sides inward. Splicing strips that can cooperate with the splicing dovetail grooves are provided on the other two sides of the special-shaped steel body. The splicing strips can be detachably and slidably connected with the splicing dovetail grooves of another special-shaped steel body. By setting splicing dovetail grooves and splicing strips on the special-shaped steel body, the special-shaped steels can be freely spliced and combined, so that operators can combine multiple special-shaped steels according to needs to meet the support force requirements, without having to purchase steels of various sizes, reducing costs. The special-shaped steels can be disassembled and reused, reducing waste;

[0004] The above-mentioned prior art solutions have the following defects: When multiple groups of special-shaped steels are spliced with each other by splicing strips, the special-shaped steels rely on the friction force of anti-slip lines to achieve mutual stability. However, relying solely on friction force is difficult to ensure the stability after splicing of special-shaped steels, thereby reducing the reliability after splicing. In view of the above situation, technical innovation is carried out on the basis of the existing high-precision special-shaped steel. Content of the Utility Model

[0005] The purpose of the utility model is to provide a high-precision special-shaped steel to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A high-precision special-shaped steel, including:

[0007] A special-shaped steel, dovetail grooves are evenly opened on the outer side wall of the special-shaped steel, a strip is evenly arranged on the outer side wall of the special-shaped steel, mounting holes are evenly opened in the round head pin, and fixing components are placed in the mounting holes.

[0008] Preferably, the fixing component includes a spring, a round head pin is arranged on the outer side of the spring, and a magnetic rod is embedded on the outer side of the round head pin.

[0009] Preferably, positioning holes are evenly formed in the outer side wall of the clamping strip, and the front and rear sides of the clamping strip are designed with arc chamfers.

[0010] Preferably, the round head pin is arranged in the mounting hole, and the round head part of the round head pin corresponds to the positioning hole.

[0011] Preferably, the clamping strip and the special-shaped steel are integrally formed by cutting. The outer side wall of the clamping strip is provided with anti-slip lines, and the clamping strip corresponds to the dovetail groove.

[0012] Preferably, the dovetail grooves and the clamping strips are evenly distributed in an annular array on the outer side of the special-shaped steel, and each group of dovetail grooves is located between two groups of clamping strips.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] In the present utility model, when the clamping strip is inserted into the dovetail groove of another group of special-shaped steel, the spring drives the round head pin to be inserted into the positioning hole by using its own elastic force. Similarly, by using the magnetic attraction of the magnetic rod, the round head pin is stably fixed in the positioning hole. In addition, the anti-slip lines on the clamping strip can effectively ensure the stability of the clamping strip inserted into the dovetail groove, thereby improving the stability after the splicing of the special-shaped steel and the special-shaped steel;

[0015] When the clamping strip is inserted into the dovetail groove, benefiting from the arc chamfer design on the front and rear sides of the clamping strip, the resistance of the round head pin to the clamping strip can be reduced, thereby improving the splicing convenience between the special-shaped steel and the special-shaped steel.

[0020] 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 making creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 - 3 , a high-precision special-shaped steel, including special-shaped steel 1. Dovetail grooves 11 are evenly opened on the outer side wall of the special-shaped steel 1. Clamping strips 12 are evenly and fixedly arranged on the outer side wall of the special-shaped steel 1. Mounting holes are evenly opened in the round head pin 13, and fixing components are placed in the mounting holes. The fixing components include springs 16. The outer side of the spring 16 is fixedly provided with the round head pin 13. A magnetic rod 14 is inlaid on the outer side of the round head pin 13. Positioning holes 15 are evenly opened on the outer side wall of the clamping strip 12. The front and rear sides of the clamping strip 12 are designed with arc chamfers. When the clamping strip 12 is inserted into the dovetail groove 11, due to the arc chamfer design on the front and rear sides of the clamping strip 12, the resistance of the round head pin 13 to the clamping strip 12 can be reduced, thereby improving the splicing convenience between the special-shaped steels 1. The round head pin 13 is slidably arranged in the mounting hole, and the round head part of the round head pin 13 corresponds to the positioning hole 15. When the clamping strip 12 is inserted into the dovetail groove 11 of another group of special-shaped steels 1, the spring 16 drives the round head pin 13 to be inserted into the positioning hole 15 by its own elastic force. Similarly, using the magnetic attraction of the magnetic rod 14, the round head pin 13 is stably fixed in the positioning hole 15. Coupled with the anti-slip pattern on the clamping strip 12, the stability of the clamping strip 12 inserted into the dovetail groove 11 can be effectively guaranteed, thereby improving the stability after the splicing of the special-shaped steels 1. The clamping strip 12 and the special-shaped steel 1 are integrally formed by cutting. The outer side wall of the clamping strip 12 is provided with an anti-slip pattern. The clamping strip 12 corresponds to the dovetail groove 11. The dovetail grooves 11 and the clamping strips 12 are evenly distributed in an annular array on the outer side of the special-shaped steel 1. Each group of dovetail grooves 11 is located between two groups of clamping strips 12.

[0022] Working principle: When the clamping strip 12 is inserted into the dovetail groove 11 of another group of special-shaped steels 1, the spring 16 drives the round head pin 13 to be inserted into the positioning hole 15 by its own elastic force. Similarly, using the magnetic attraction of the magnetic rod 14, the round head pin 13 is stably fixed in the positioning hole 15. Coupled with the anti-slip pattern on the clamping strip 12, the stability of the clamping strip 12 inserted into the dovetail groove 11 can be effectively guaranteed, thereby improving the stability after the splicing of the special-shaped steels 1. When the clamping strip 12 is inserted into the dovetail groove 11, due to the arc chamfer design on the front and rear sides of the clamping strip 12, the resistance of the round head pin 13 to the clamping strip 12 can be reduced, thereby improving the splicing convenience between the special-shaped steels 1.
