Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of riveting nuts, in particular to an anti - cracking device for connecting a riveting nut and a plastic bracket. Background Art
[0002] The riveting nut, also known as a blind nut, is used for fastening connections in various metal plate, pipe and other manufacturing industries; however, when the existing riveting nuts are used on plastic parts, it is necessary to pre - embed nuts or use spring washers on the plastic parts, resulting in poor versatility and high cost. Content of the Utility Model
[0003] The purpose of the utility model is to provide an anti - cracking device for connecting a riveting nut and a plastic bracket aiming at the deficiencies of the prior art, and solve the problems of poor versatility and high cost when the existing riveting nuts are used on plastic parts.
[0004] The utility model is realized by adopting the following technical scheme:
[0005] An anti - cracking device for connecting a riveting nut and a plastic bracket includes a riveting nut, a plastic bracket and a metal gasket; the riveting nut passes through the plastic bracket and is sleeved with a metal gasket.
[0006] Preferably, the plastic bracket includes a connection hole and a protruding part arranged on the outer circle of the connection hole.
[0007] Preferably, the inner - circle diameter of the metal gasket is larger than the diameter of the connection hole of the plastic bracket.
[0008] Compared with the prior art, the utility model has the following beneficial technical effects:
[0009] When the riveting nut and the plastic bracket are riveted, the utility model adds a metal gasket to improve the strength of the thin - wall in the riveting area of the plastic bracket, with high versatility and low cost. Description of the Drawings
[0010] Figure 1 It is a schematic diagram before riveting of the overall structure of the utility model;
[0011] Figure 2 It is a schematic diagram after riveting of the overall structure of the utility model;
[0012] Figure 3 It is a cross - sectional view after riveting of the overall structure of the utility model;
[0013] In the figure, 1, riveting nut; 2, plastic bracket; 3, metal gasket; 21, connection hole; 22, protruding part. Detailed Description of the Invention
[0014] As Figures 1-3As shown: An anti - cracking device for connecting a blind rivet nut and a plastic bracket, comprising a blind rivet nut 1, a plastic bracket 2 and a metal gasket 3; The blind rivet nut 1 passes through the plastic bracket 2 and is sleeved with a metal gasket 3.
[0015] The plastic bracket 2 includes a connection hole 21 and a protruding portion 22 provided on the outer circle of the connection hole 21.
[0016] The inner - ring diameter dimension of the metal gasket 3 is larger than the diameter dimension of the connection hole 21 of the plastic bracket 2; To meet the riveting requirements.
[0017] Embodiment 1
[0018] The blind rivet nut 1 uses an M8 stainless - steel flat - head vertical - thread blind rivet nut, the riveting thickness is 1.0 mm - 3.5 mm, and the thickness of the riveting area of the plastic bracket 2 is 2.5 mm. To prevent the plastic thin - wall in the riveting area from cracking, a metal gasket 3 of about 1 mm is added before riveting to enhance the strength of the plastic thin - wall in the riveting area. Broaden its usage environment and operating conditions.
