Abstract
Description
Technical Field
[0001] The utility model relates to a toothed right-angle connector. Background Art
[0002] The right-angle connector is mainly used for connecting the upright column and the cross arm of earthquake-resistant support products. Traditional right-angle connectors are all in the form of round holes and are connected to the upright column or cross arm through hexagon head bolts and plastic wing nuts. The bearing capacity value in the vertical direction depends on the connection between the nut and the C-shaped channel steel. The anti-slip load capacity of the nut generally relies on the threaded connection between the nut and the screw cap. Only relying on the threaded connection between the nut and the screw cap will result in a low anti-slip load capacity, unable to effectively carry out anti-slip, and further causing the problem of unstable connection between the upright column and the cross arm. Content of the Utility Model
[0003] The purpose of the utility model is to provide a toothed right-angle connector, which can improve the anti-slip load of the right-angle connector.
[0004] The technical solution to achieve the above purpose is: a toothed right-angle connector, including a right-angle plate. The shape of the right-angle plate is L-shaped. A through groove is provided through one surface of the right-angle plate, and a mounting groove is provided through the other surface of the right-angle plate. The through groove and the mounting groove are distributed at 90°. A plurality of card slots are provided on the surface of the through groove. A gasket is movably connected in the through groove. A plurality of card teeth are provided on the back of the gasket. Each card tooth is not located in its respective card slot. The shape of the card tooth fits the card slot. A through hole is provided at the center of the surface of the gasket. A nut is movably connected in the through hole, and the nut passes through the through groove at the same time.
[0005] Preferably: The shape of the mounting groove is the same as that of the through groove. Two movable blocks are provided on the back of the gasket. The movable blocks are movably connected in the through groove. Threaded holes are provided at both ends of the through groove. A limit pin is threadedly connected in the threaded hole. The surface of the limit pin abuts against the surface of the movable block.
[0006] Preferably: Three mounting holes are provided on both sides of the right-angle plate. Triangular plates are provided on both sides of the right-angle plate. Three mounting posts are provided on the surface of the triangular plate. Each mounting post is located in its respective mounting hole.
[0007] Preferably: The right-angle plate is made of stainless steel.
[0008] Preferably: The shape of the limit pin is T-shaped, and anti-slip threads are provided on the surface of the limit pin.
[0009] Preferably: A magnet is provided in the mounting hole, and the mounting post is made of iron material.
[0010] Technical effects of the present utility model:
[0011] 1) The device includes a right-angle plate in an L shape. A through groove is provided through one surface of the right-angle plate, and a mounting groove is provided through the other surface of the right-angle plate. The through groove and the mounting groove are distributed at 90°. Multiple card slots are provided on the surface of each through groove. A gasket is movably connected in each through groove. To avoid a low anti-slip load capacity, multiple card teeth are provided on the back of the gasket. Each card tooth is not located in its respective card slot. Through the mutual engagement between the card teeth and the card slots, the anti-slip load capacity can be effectively improved.

In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and should not be construed as indicating or implying relative importance.
[0021] The present utility model will be further described below in conjunction with the accompanying drawings.
[0022] First Embodiment:
[0023] Please refer to Figures 1-5 , a toothed right-angle connector of the present utility model includes a right-angle plate 1. The shape of the right-angle plate 1 is L-shaped. A through groove 101 is provided through one surface of the right-angle plate 1, and a mounting groove 1011 is provided through the other surface of the right-angle plate 1. The through groove 101 and the mounting groove 1011 are distributed at 90°. A plurality of card slots 102 are provided on the surface of each through groove 101. A gasket 2 is movably connected in each through groove 101. To avoid a relatively low anti-slip load capacity, a plurality of card teeth 203 are provided on the back surface of the gasket 2. Each card tooth 203 is not located in its respective card slot 102. By the mutual engagement between the card teeth 203 and the card slots 102, the anti-slip load capacity can be effectively improved. The shape of the card teeth 203 fits the card slots 102. A through hole 202 is provided at the center of the surface of the gasket 2. A nut 3 is movably connected in the through hole 202. The nut 3 passes through the through groove 101 at the same time to facilitate threaded connection with the outside.
[0024] Second Embodiment:
[0025] On the basis of the first embodiment, the shape of the mounting groove 1011 is the same as that of the through groove 101, which can facilitate the adjustment of the position of the connector. To avoid damage to the card slots 102 when the load is large, two movable blocks 201 are provided on the back surface of the gasket 2. The movable blocks 201 are movably connected in the through groove 101. Threaded holes 104 are provided at both ends of the through groove 101. A limit pin 5 is threadedly connected in the threaded hole 104. The surface of the limit pin 5 abuts against the surface of the movable block 201. After the nut 3 is installed, rotate the two limit pins 5 to make the two limit pins 5 abut against the surface of the two movable blocks 201. The main stress points are on the two limit pins 5, which can effectively reduce the pressure on the card teeth 203 and the card slots 102.
[0026] Of course, to avoid a large pulling force that may cause the bending angle of the right-angle plate 1 to be greater than or less than 90 degrees, three mounting holes 103 can be provided on both sides of the right-angle plate 1. Triangular plates 6 are provided on both sides of the right-angle plate 1, and three mounting posts 601 are provided on the surface of each triangular plate 6. Each mounting post 601 is located within the corresponding mounting hole 103.
[0027] Preferably, the right-angle plate 1 is made of stainless steel to effectively prevent the right-angle plate 1 from rusting, which may lead to loose connections. The limiting pin 5 is in a T shape, and anti-slip patterns are provided on the surface of the limiting pin 5 to facilitate the rotation of the limiting pin 5. A magnet is provided in the mounting hole 103, and the mounting post 601 is made of iron material.
