Detailed Description
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. Unless otherwise defined, all terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. It will be further understood that the conventional terms should be interpreted as having a meaning that is consistent with their meaning in the relevant art and this disclosure. The present disclosure is to be considered as an example of the utility model and is not intended to limit the utility model to the particular embodiments.
The embodiment provides a steel rod with a dovetail groove 2, which is mainly used for connecting external equipment. The structure includes: the lamp post comprises a steel rod body 1, wherein a dovetail groove 2 is formed in the surface of the steel rod body 1, the dovetail groove 2 comprises an opening end 2-1, a side wall 2-2 and a bottom end 2-3, the width of the opening end 2-1 is smaller than that of the bottom end 2-3, the joint of the side wall 2-2 and the surface of the lamp post is rounded, and the joint of the side wall 2-2 and the bottom end 2-3 is rounded.
The main structure of the utility model is a steel rod, as shown in figure 1, the side wall of the steel rod cylinder comprises a dovetail groove 2, the dovetail groove 2 can be embedded into the side wall of the steel rod main body 1, penetrates through the upper bottom and the lower bottom of the steel rod and can also extend out to a depth from the center of the steel rod cylinder, and the first structure is a consumable material, so that the second structure is used, and the thickness of the dovetail groove 2 is consistent with that of the side wall of the steel rod cylinder in the whole structure. As shown in FIGS. 2 to 5, the dovetail groove 2 is configured such that the open end 2-1 is small and the bottom end 2-3 is large. The dovetail groove 2 is mainly arranged to facilitate the installation of external equipment on the steel bar main body 1, and for better implementation, the structure of the dovetail groove 2 is further set, the included angle between the side wall 2-2 and the bottom end 2-3 of the dovetail groove 2 is 50-70 degrees, and the included angle between 50 and 70 degrees is such that an object connected at the dovetail groove 2 cannot slide out of the dovetail groove 2, so that the installation is also facilitated. In terms of the number of the dovetail grooves 2, since the bottom ends 2-3 of the dovetail grooves 2 extend towards the inside of the steel bar, if too many dovetail grooves 2 are provided, the bottom ends 2-3 of the dovetail grooves 2 are connected, unless the depth of the dovetail grooves 2 is reduced, but the depth of the dovetail grooves 2 becomes shallow, so that external equipment is unstable and easy to fall off when being connected, therefore, the number of the dovetail grooves cannot be too large, in the embodiment, the number of the dovetail grooves 2 is between 1-4, and when the dovetail grooves 2 are provided, the dovetail grooves 2 are distributed in the four directions of the upper, lower, left and right of the side wall of the steel bar column according to the number of the dovetail grooves 2. In addition, the specific position where the dovetail groove 2 is arranged is also greatly related to the shape of a steel rod cylinder, which can be various cylinders, and in the embodiment, there are two structures, namely, the steel rod body 1 is an octagonal prism. When the steel bar of octagonal prism is provided with the dovetail groove 2, the dovetail groove 2 is provided in the center of one side surface of the steel bar body 1 of octagonal prism for the sake of appearance. The dovetail groove 2 is arranged not to exceed the width of the side face, and the width of the opening end 2-1 of the dovetail groove 2 is 40% -100% of the width of the side face where the opening end is located. If the width of the opening end 2-1 is too small, it is difficult to install the external device because the port is too small, if the opening is too large, it is easy to limit the shape of the steel rod, besides, according to the number of the dovetail grooves 2, if the opening is too large, the appearance is affected, and the bottom end 2-3 of the dovetail groove 2 is beyond the steel rod body 1. When 1-4 dovetail grooves 2 are arranged on the steel bar with the octagonal prism, the following can be seen respectively: if a dovetail groove 2 exists, the dovetail groove can be arranged on any surface of the side wall of the steel bar main body 1; if two dovetail grooves 2 are provided, the dovetail grooves are arranged on two surfaces which are symmetrical up and down or symmetrical left and right on the side wall of the steel bar main body 1, and if three dovetail grooves 2 are provided, the dovetail grooves are arranged on two surfaces which are symmetrical up and down or symmetrical left and right on the side wall of the steel bar main body 1 and a surface which is between the two symmetrical surfaces and forms an angle of 45 degrees with the two symmetrical surfaces; if there are four dovetail grooves 2, then set up on the symmetry of upper and lower, bilateral symmetry's face, four dovetail grooves 2 evenly set up, and two adjacent dovetail grooves 2 all become 45. Secondly, the steel rod body 1 is a cylinder. The cylindrical body is more in line with the structure of the existing steel bar, because the side surface of the cylindrical steel bar is arc-shaped, the arrangement of the cylindrical steel bar is different from that of the octagonal prism steel bar when the dovetail groove 2 is arranged, the cylindrical body is mainly arranged on the circumference of the side surface of the cylindrical body, and the width of the opening end 2-1 of the dovetail groove 2 accounts for 5% -12.5% of the circumference of the steel bar main body 1. The problem that the external equipment is too small to be installed and too large to fall off when the external equipment is installed is also prevented. The same as the above arrangement, it is also arranged in four directions of up, down, left and right, because the side surface of the steel bar is not divided into several surfaces, if there is a dovetail groove 2, it can be arbitrarily arranged on the side wall of the dovetail groove 2 main body; if two dovetail grooves 2 are provided, the dovetail grooves are arranged in the vertical direction or the left-right direction, namely the two dovetail grooves 2 are symmetrical to each other; if two dovetail grooves 2 are provided, the dovetail grooves are arranged in three directions of up, down, left and right, and the angle between the dovetail grooves 2 is 90 degrees or 180 degrees; if there are two dovetail grooves 2, then set up four directions about the top and bottom, the angle between the dovetail groove 2 that any dovetail groove 2 is close to it is 90 degrees. In addition to the above, the size of the dovetail groove 2 also varies with the size of the steel bar body 1, and when the steel bar body 1 is wide, the open end 2-1 and the bottom end 2-3 of the dovetail groove 2 are also wide.
The steel rods are made of low-carbon alloy steel, such as Q235, Q345, Q355 and Q460, and the steel rods with different specifications are convenient to supply for different requirements.
The dovetail groove 2 is mainly used for connecting external equipment, in the embodiment, the bottom end 2-3 of the dovetail groove comprises functional interfaces used for increasing and decreasing the external equipment, a buckle is needed when the external equipment is connected, the external equipment and the steel rod are connected into a whole through the buckle, two ends of the buckle are parallel to each other, the other two ends of the buckle are both outwards arc-shaped, two parallel ends are longer, and a hole used for adjustment is formed in the middle of the buckle. During operation, the longer end of the fastener enters the dovetail groove 2 along the direction from the upper bottom to the lower bottom of the steel rod, then the longer end of the fastener is parallel to the cross section of the steel rod through adjustment, so that the fastener is clamped in the dovetail groove 2 and is fixed by installing screws, wherein the shorter end of the fastener is smaller than the opening end 2-1 of the dovetail groove; the longer end of the buckle is larger than the size of the open end 2-1 of the dovetail groove and smaller than or equal to the size of the bottom end 2-3 of the dovetail groove.
Although embodiments of the present invention have been described, various changes or modifications may be made by one of ordinary skill in the art within the scope of the appended claims.
