Description

Connection structure of angle steel and connection

The present invention relates to a connecting structure, in particular to a connecting structure of an angle steel and a connecting object.

Casters are a very convenient tool that can be installed under many furniture, such as office chairs, cabinets, hangers, etc., so that these furniture can be moved, so that they can be easily placed in any corner of the living space. In addition, the casters can also be connected with the angle steel, so that the heavy objects supported on the angle steel can also be easily moved. Therefore, some designs for connecting casters and angles have appeared on the market. Similarly, the adjustable feet can replace casters, so that the installed furniture becomes fixed, but the height can be adjusted.

Please refer to Figure 1, which is a schematic diagram of the improved structure of the carrier tool adapter seat in Taiwan New Patent Publication No. M548037. The structural improvement of the bearing tool adapter seat is a connecting device between casters and angle steel, which mainly includes an adapter seat 1 which is connected with an assembled angle steel 2 to form a tool holder body for carrying. The adapter seat 1 includes two supporting pieces 3 that are adjacently connected to form an angle. The bottom ends of the two supporting pieces 3 are connected to a square plate 4, and a caster 5 is connected under the plate 4. The supporting piece 3 is arranged with a plurality of through holes. 6. The bottom ends of the two through holes 6 adjacent to the flat plate are provided with positioning hooks 7, and the two positioning hooks 7 are used for the bottom end of the assembled angle steel 2 to be embedded and positioned. When in use, the adapter seat 1 is used to assemble the angle steel 2 to form a load-bearing tool holder. The end face of the assembly angle steel 2 can be punched with several through holes 8. When the assembly angle steel 2 is assembled with the adapter seat 1, The adapter seat 1 is wrapped on the outside of the assembly angle steel 2 and adjacently attached. The assembly angle steel 2 is correspondingly located on the inside of the two supporting pieces 3, and the positioning hook 7 at the bottom of the through hole 6 is used for the assembly angle 2 to be embedded to achieve a stable fixed position. As a result, the through holes 6 of the two supporting pieces 3 and the through holes 8 of the assembly angle steel 2 are made to correspond to each other, and then a screw assembly 9 is correspondingly locked, so that the adapter seat 1 and the assembly angle steel 2 are locked together.

The flat plate 4 with the improved structure of the carrier tool joint seat is formed by one of the two supporting pieces 3 extending and bending. If it is not welded to the end of the other supporting piece 3, it is easy to be bent by the external force from the caster 5. The same problem occurs when the caster 5 is replaced with an adjustable foot. However, such an approach consumes man-hours and materials. Therefore, an innovative connecting structure of angle steel and connecting object is needed to improve this problem.

The present invention will be described in more detail by referring to the following embodiments.

Please refer to Figures 2 to 5. Figure 2 is a schematic diagram of a connection structure 10 of angle steel and a connector according to an embodiment of the present invention, and Figure 3 is a schematic diagram of a stamped metal plate 10a for making the connection structure 10 of the angle steel and connector (Top view direction), FIG. 4 is a use state diagram of the connecting structure 10 of the angle steel and the connecting object, and FIG. 5 shows the state of connecting the connecting structure 10 of the angle steel and the connecting object and an angle steel 20. The connecting structure 10 of the angle steel and the connecting object is formed by stamping a metal plate. The metal plate can be stainless steel or galvanized iron, and it needs to be able to resist bending by external forces. The appearance of the metal plate after punching but before forming the connecting structure 10 of the angle steel and the connecting object is as shown in the stamped metal plate 10a. When understanding the structure and function of the connecting structure 10 of the angle steel and the connecting object, please refer to Figures 2 and 3 at the same time. .

The connecting structure 10 of the angle steel and the connecting object includes a central bearing area 11 whose shape is close to a right-angled triangle. In terms of shape, the central carrying area 11 has a first side 11a, a second side 11b, and a hypotenuse 11c. After the outer periphery of the punched metal plate 10a is cut or punched out as shown in FIG. 3, a through hole 111 is punched out inside the central bearing area 11 (for example, at the centroid). In this embodiment, the appearance of the through hole 111 is circular; however, in other embodiments, it may also have various symmetrical shapes, such as a regular hexagon. In Fig. 3, the dashed line indicates the cut area, and the shaded area indicates the punched-out part. In order to facilitate the subsequent bending process and avoid injury to the user, the three corners of the central bearing area 11 are rounded. The inner surface of the through hole 111 is smooth, and is used to fix a caster or an adjustable foot. In this embodiment, a nut 112 (or a metal tube with a smooth inner surface) is fixed in the through hole 111 for connecting a caster or an adjustable foot, for example, through a screw on the caster. The appearance shape of the nut 112 matching the through hole 111 is also circular; however, in other embodiments, the appearance shape of the nut 112 may also be a regular hexagon, such as a standard nut. The nut 112 and the through hole 111 are fixed by welding. Since the thickness of the stamped metal plate 10a is not thick, the length of the nut 112 or a metal tube will exceed the thickness of the stamped metal plate 10a, and the protruding end of the nut 112 or a metal tube protrudes toward the extension direction of the fixed plate area.

The central carrying area 111 is vertically bent and connected to a first fixing plate area 12 and a second fixing plate area 13 on the first side 11a and the second side 11b that are perpendicular to each other. The first fixing plate area 12, the second fixing plate area 13 and the central bearing area 111 are formed by stamping from the same sheet of metal plate, and the first fixing plate area 12 and the second fixing plate area 13 respectively face the same side of the central bearing area 111 The final shape is formed by bending substantially 90 degrees. The appearance of the first fixing board area 12 and the second fixing board area 13 are the same, close to a rectangle, and the corners are rounded to avoid injury to inadvertent users.

A first connecting hole 121 is formed inside the first fixing plate area 12, and a second connecting hole 131 is formed inside the second fixing plate area 13. According to the present invention, the number of the first connecting hole 121 and the second connecting hole 131 is not limited to one, as long as it can help to fix the angle steel, any number can be used. The shape of the first connecting hole 121 and the second connecting hole 131 is a racetrack shape. In order to be effectively fixed to the angle steel openings by screws, the longer directions of the connecting holes are perpendicular or parallel to the corresponding sides of the central bearing area 11 (in this embodiment, the relationship is parallel). Please refer to Fig. 4 for the connection structure of angle steel and connecting object 10 and the connection method of angle steel and casters. The lower part of the connecting structure 10 of the angle steel and the connecting object is connected with a caster 30 (or adjustable foot 50, as shown in FIG. 6) through a nut 112, and the upper part is fixedly connected with the opening 21 on the caster 30 through a screw assembly 40. Furthermore, the angle steel 20 is connected with the connection structure 10 of the caster downward in the arrow direction, the first connection hole 121 or the second connection hole 131 is connected with the opening 21, and finally the screw assembly 40 is used for locking.

The hypotenuse 11c of the central load-bearing area 11 is vertically bent and connected to a reinforced area 14. The appearance of the reinforced area 14 is close to a rectangle with rounded corners. If there is no strengthening zone 14, only the triangular area of the central bearing zone 11 cannot resist the external force applied by the caster 30 and the angle steel 20 and will be bent and deformed. But with the addition of the strengthening zone 14, the stiffness against bending moment is increased. The strengthening zone 14 only bends the part extending from the edge of the central load-bearing zone 11, which can achieve the effect of using welding and additional materials in the prior art, which is a key technical improvement of the present invention.

In order to strengthen the fixed angle steel 20, the present invention has the following design. As shown in FIG. 3, the central carrying area 11 removes a rectangular area 12a and 13a along the edges of the first fixing plate area 12 and a second fixing plate area 13, respectively, and along the two short sides of the rectangular areas 12a and 13a. Cut a cutting section 12b and 13b, and a part of the metal plate between the two cutting sections 12b and 13b is bent upward to form a fixed protrusion (a first fixed protrusion 11d and a second fixed protrusion 11e), the first The space between the fixing protrusion 11d and the adjacent first fixing plate area 12, and the space between the second fixing protrusion 11e and the adjacent second fixing plate area 13 can be used to fix one side steel plate of the angle steel 20, as shown in the figure 5 is shown. In this way, the fixing between the angle steel 20 and the connecting structure 10 of the angle steel and the connecting object can be more precise, and it also has the effect of preventing fools. More importantly, if the steel plate of the angle steel is too thick or too thin, the first fixing protrusion 11d and the second fixing protrusion 11e can be further adjusted by bending to meet the dimensional characteristics of the connecting angle.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention. Anyone with ordinary knowledge in the technical field can make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, The scope of protection of this new model shall be subject to the scope of the attached patent application.
