Example 1
As shown in fig. 1 to 3, the present embodiment provides a universal connector comprising a connector body 1 and a fastener 14, the connector body 1 being connectable to a first panel 2 by the fastener 14;
The connector body 1 comprises a top surface, a bottom surface and a side surface connecting the top surface and the bottom surface, wherein the side surface is provided with a reinforcing rib 11, the reinforcing rib 11 comprises a front end surface 111 and a rear end surface 112, and the cross section of the reinforcing rib 11 gradually increases along the direction from the front end surface 111 to the rear end surface 112; when the connector body 1 is inserted into the fastening groove 31 of the second plate 3, the reinforcing ribs 11 can be embedded in the side walls of the fastening groove 31 through the front end face 111 having a smaller cross-sectional area;
The connector body 1 can be connected with the second plate 3 through the interference fit of the reinforcing ribs 11 and the side walls of the fastening groove 31, and when the connector body 1 is connected with the first plate 2 and the second plate 3 at the same time, the first plate 2 is connected with the second plate 3.
Since the connector body 1 is located in the fastening groove 31 of the second plate 3, the connector body 1 can be hidden after the two plates are connected, meanwhile, since the reinforcing ribs 11 are arranged on the side surfaces of the connector body 1, the front end surfaces 111 of the reinforcing ribs 11 are small, and the rear end surfaces 112 are large, when the connector body 1 is inserted into the fastening groove 31 matched with the connector body, the reinforcing ribs 11 can be embedded into the side walls of the reinforcing ribs 11, and nails are similarly driven into wood, and at the moment, the reinforcing ribs 11 can be in interference fit with the side walls of the fastening groove 31, so that the connector body 1 is firmly connected with the second plate; the number and the size of the reinforcing ribs are adjusted according to the specific requirements of the connector body 1, the sizes and the materials of the first plate 2 and the second plate 3 and the connection strength of the first plate 2 and the second plate 3, and the number of the reinforcing ribs 11 is two in the embodiment.
The fastening groove 31 formed on the second plate 3 is used as a female part matched with the universal connecting piece in pairs by utilizing the modern numerical control technology corresponding to the universal connecting piece, so that the number of parts is reduced, the invisible connection between furniture plates is realized by using fewer parts and a simple mode, the connection is stable and reliable, the production cost is low, the installation efficiency is high, and the mass production is convenient.
When the connection strength requirement of the first plate 2 and the second plate 3 is higher, the overall shape of the connector body 1 may be set to be in a condition of narrow upper part and wide lower part, specifically, as shown in fig. 1-2, the connector body 1 includes a middle section and semicircular tables (the circular truncated cone shape generally refers to that the top surface and the bottom surface are parallel to each other and are both circular surfaces, the connecting line of the centers of the two circular surfaces is perpendicular to the top surface and the bottom surface, the longitudinal section of the circular truncated cone shape is a three-dimensional figure of an isosceles trapezoid, the semicircular truncated cone refers to a part of a truncated cone shape cut by a connecting line plane of the centers of the two circular surfaces), the top surface and the bottom surface are parallel to each other, and the longitudinal section of the connector body 1 is of an isosceles trapezoid; the front and rear surfaces of the middle section are rectangular, the left and right surfaces connected with the semicircular table are isosceles trapezoids, and the top surface and the bottom surface of the connecting piece body 1 are rectangular combined two semicircular structures; accordingly, a plurality of fasteners 14 may be provided, in this embodiment, the fasteners 14 are respectively disposed along the central axes of the two semicircular tables, and when the middle section is designed to be longer for the purpose of increasing the connection strength, the fasteners 14 may also be disposed on the middle section; the location and number of the fasteners 14 can be adjusted according to the length of the connector body 1 and the strength of the connection between the first plate 2 and the second plate 3.
In this embodiment, the reinforcing ribs 11 are disposed along the side surfaces of the middle section and are disposed on two opposite sides of the middle section respectively, and the length direction of the reinforcing ribs 11 is parallel to the movement direction of the connector body 1 when it is inserted into the fastening slot 31; the front half round table and the rear half round table of the connecting piece body 1 are not provided with reinforcing ribs 31; the purpose is that when the side wall of the fastening groove 31 is not provided with the accommodating groove of the reinforcing rib 11, the connecting piece body 1 is conveniently inserted into the fastening groove 31, and the accommodating groove is formed by embedding the reinforcing rib 11; in addition, since the opposite side walls of the fastening groove 31 simultaneously press the connector body 1, the receiving groove of the reinforcing rib 31 is more easily formed; for the end half round table and the rear end half round table, since the rear end of the connector body 1 is not provided with a device for abutting, the rear end is not provided with a reinforcing rib, and the front end is required to be pressed into the side wall of the fastening groove 31 by manual external force, the front end is relatively hard, even if the front end is provided with the reinforcing rib 11 and can be inserted into the fastening groove 31, the front end reinforcing rib 11 is easy to separate and unstable due to the fact that the rear end is not provided with stable pressure, the whole connector body 1 is unstable in the fastening groove 31, the front end is not provided with the reinforcing rib 11, and therefore the front end of the connector body 1 can be in close contact with the side wall of the fastening groove 31, and the positioning of the connector body 1 in the fastening groove 31 is more accurate.
In this embodiment, since the top surface area of the connector body 1 is small, and the bottom surface area is large, the opening of the fastening groove 31 is small and the groove bottom is large in cooperation with the connector body 1, when the connector body 1 is located in the fastening groove 31, the side wall of the fastening groove 31 with a certain inclination can generate resistance to the connector body 1, so that the connector body 1 can be effectively prevented from falling out from the opening of the fastening groove 31.
For convenience in installation and processing, in this embodiment, the included angle between the oblique side of the isosceles trapezoid obtained by the longitudinal section of the connector body 1 and the vertical direction is 0-15 degrees. Of course, the range of the angle can be adjusted according to the requirements of different materials, thickness and connection strength of the plate.
In order to further improve the clamping tightness of the reinforcing rib 11 and the reinforcing rib groove 32, as shown in fig. 3, the reinforcing rib 11 further includes a lower surface 115, an outer surface 114, an upper surface 113 and a connection surface which are sequentially connected, the connection surface is connected with the side surface, when the connector body 1 is positioned in the fastening groove 31, the upper surface 113 is opened towards the fastening groove 31, the lower surface 115 is opened towards the bottom of the fastening groove 31, and the upper surface 113 is parallel to the top surface and the bottom surface; that is, the reinforcing bars 11 are hardly moved in the vertical direction toward the opening of the fastening groove 31, so that the connection state is more firm; the distance between the upper surface 113 and the lower surface 115 gradually increases from the front end surface 111 to the rear end surface 112, and gradually increases from the connection surface to the connection surface, that is, the cross-sectional area of the stiffener 11 gradually increases from the end of the stiffener 11 away from the side surface to the end of the stiffener 11 near the side surface, and the lower surface 115 and the outer surface 114 may have a structure in which two intersecting surfaces are spliced, or may have a smooth curved surface.
