Detailed Description
The present utility model will be further described with reference to the accompanying drawings and detailed description, wherein it is to be understood that, on the premise of no conflict, the following embodiments or technical features may be arbitrarily combined to form new embodiments.
As shown in fig. 2 to 5, an integrated nut 100 for a roof rack is movably installed in an expansion groove A1 of a roof rack a, and the integrated nut 100 for a roof rack includes a nut body 1, a gasket body 2, and a connecting piece 3; the gasket body 2 is arranged above the nut body 1, the widths D1/D2 of the nut body 1 and the gasket body 2 are both larger than the notch width T1 of the expansion groove, and the distance D3 between the nut body 1 and the gasket body 2 is larger than the thickness T2 of the notch of the expansion groove; one end of the connecting sheet 3 is fixedly connected with the nut main body 1, and the other end of the connecting sheet 3 is fixedly connected with the gasket main body 2; the width D4 of the connecting sheet 3 is smaller than the notch width T1 of the expanding groove.
According to the application, the nut main body 1 and the gasket main body 2 are fixed together through the design of the connecting sheet 3, so that the problem that parts are lost due to falling in the expansion groove A1 in the installation process is avoided, and on the other hand, during installation, the lifting ring screw 4 is directly screwed into the nut body by utilizing the limit of the connecting sheet 3 and the horizontal direction of the expansion groove A1, so that the integrated nut 100 for the whole roof frame can be screwed without extending into the expansion groove A1 to fix the nut, and the installation is more convenient.
As a further preferable scheme, the number of the connecting pieces 3 is two, the connecting pieces are respectively positioned on two corresponding sides of the nut main body 1 and the gasket main body 2, one end of each connecting piece 3 is fixedly connected with the nut main body 1, and the other end of each connecting piece 3 is fixedly connected with the gasket main body. Two connecting pieces 3 are preferably designed to improve the connection strength between the nut body 1 and the gasket body 2 and the sliding smoothness of the nut body 1 and the gasket body 2 in the expansion groove A1.
As a further preferable scheme, a first hollow cavity 21 is formed in the middle of the gasket body 2, a second hollow cavity 11 having the same central axis as the first hollow cavity is formed in the middle of the nut body 1, the aperture of the first hollow cavity 21 is larger than that of the second hollow cavity 11, and an internal thread 12 is formed in the second hollow cavity 11. According to the application, the nut main body 1 and the gasket main body 2 are connected together through the connecting sheet 3, and the coaxial design of the hollow cavity I21 and the hollow cavity II 11 enables the turning tapping to be easier to realize when the integrated nut 100 for the roof rack is processed.
As a further preferable aspect, the thickness D1 of the nut body 1 is larger than the thickness D2 of the gasket body, and the larger the thickness of the nut body 1 is, the larger the threaded connection area with the eye screw 4 is, and the higher the firmness is. The thickness D2 of the nut body 1 should be smaller than the depth T3 of the expansion groove to ensure that the nut body 1 can slide movably along the length direction of the notch in the expansion groove A1.
As a further preferable scheme, the connecting piece 3 is an arc piece or a half frame piece. The connecting piece 3 has the function of connecting the nut main body 1 and the gasket main body 2, and the parts are prevented from being lost due to falling in the expansion groove A1 in the installation process. The design of the arc-shaped piece or the half-frame piece is less likely to scratch the hand.
As a further preferable mode, the nut body 1, the gasket body 2 and the connecting piece 3 are integrally formed. In order to further improve the connection strength and the processing convenience of the nut body 1 and the gasket body 2, the nut body 1, the gasket body 2, and the connecting piece 3 are preferably integrally formed.
As a further preferable mode, the nut body 1, the gasket body 2 and the connection are all made of metal structural members made of aluminum alloy materials. Considering that the nut main body 1 is stressed greatly when being threaded and screwed, the material of the nut main body needs certain strength and hardness, and is designed to be the same aluminum alloy material as the roof rack A, so that the requirement of thread machining can be ensured, and obvious scratches can not be left during installation, thereby protecting the roof rack A.

In the application, the integrated nut can be matched with a common screw for use and can also be matched with a flying ring screw for use. The eye screw is directly screwed in the integrated nut by hand without tools, so that the installation is more convenient. However, because the protruding height is relatively large, the screw fixing device is more suitable for fixing a plurality of screws (such as a curtain and the like) on a roof rack for a long time by matching common screws with integrated nuts, so that in practical application, screws with different forms are selected according to different needs.
The process of installing the integrated nut 100 for the roof rack is as follows:
(1) Installing the nut body 1 with the gasket body into the expansion groove A1 from the side opening of the expansion groove A1 of the roof rack A;
(2) The lifting screw 4 is screwed into the hollow cavity II 11 of the nut body 1, the lifting screw 4 is rotated, the integral nut 100 for the whole roof rack can be directly screwed by utilizing the limit of the connecting sheet 3 and the horizontal direction of the expansion groove A1, the fixing nut in the expansion groove A1 does not need to be stretched, and the installation is more convenient.
The above embodiments are only preferred embodiments of the present utility model, and the scope of the present utility model is not limited thereto, but any insubstantial changes and substitutions made by those skilled in the art on the basis of the present utility model are intended to be within the scope of the present utility model as claimed.
