The rivet pressing nut in the prior art has the advantages that some special installation spaces or operators cannot pay attention to the rivet pressing nut, the angle of the wrench can be inclined, the screw and the rivet pressing nut are poor in centering performance, thread abrasion or damage of the opening of the nut is further caused, a counter bore is added to one end of the rivet pressing nut with embossing teeth to serve as a guide hole, the centering performance of the rivet pressing nut during screw installation is improved, the rivet pressing nut is connected with the screw to play a good guiding role, abrasion of the rivet pressing nut during connection is reduced, and the rivet pressing nut serving as a novel fastener is widely applied to assembly of various products.
Description
Technical Field
The utility model relates to the technical field of hardware processing, in particular to a pressure riveting nut with a guide function.
Background
The press riveting nut is a nut applied to press riveting on a thin plate or a metal plate, is circular in appearance, is provided with embossing teeth and a guide groove at one end and is often connected with a screw, does not attack an internal thread during assembly in order to solve the problem of mounting parts on the thin plate, does not need to weld the nut, is firm, convenient and quick to rivet, and is widely applied to the assembly of various products as a novel fastener.
According to the pressure riveting nut in the prior art, special installation spaces or unnoticed time of an operator can cause the angle deviation of a wrench, so that the centering performance of a screw and the pressure riveting nut is poor, and further the abrasion or damage phenomenon of screw teeth at the opening part of the nut is caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problems that the screw thread at the opening part of the nut is abraded or damaged due to poor alignment of a screw and a pressure riveting nut caused by some special installation angles.
The purpose and the effect of the utility model are achieved by the following specific technical means:
the utility model provides a pressure rivet nut with direction, is cylindrical nut including the nut main part, and the screw hole upper portion processing that the inside embedding of nut main part set up has the chamfer, and chamfer upper portion processing has columniform guiding hole, and nut main part top is provided with the annular boss of circle, and the external diameter periphery of boss is processed and is pressed the knurling tooth.
Further preferred embodiments: the guiding hole is arranged at the top of the nut main body.
Further preferred embodiments: the inside wall of guiding hole and screw can be dismantled and be connected, and the hardness at screw hole and screw riveting position is more than HRC 35.
Further preferred embodiments: the embossing teeth are a circle of annular sharp teeth which are uniformly distributed.
Further preferred embodiments: the cross section of the chamfer forms an inverted trapezoid, and the inner diameter of the bottom of the chamfer is smaller than that of the guide hole.
Has the advantages that:
one end of the pressure riveting nut with the knurling teeth is additionally provided with a counter bore as a guide hole, so that the centering performance of the pressure riveting nut in the process of installing the screw is improved, and the pressure riveting nut is connected with the screw to play a good role in guiding, so that the mutual abrasion in the process of connection is reduced.

Fig. 3 is a front view of the screw according to the present invention.
In fig. 1-3, the correspondence between the component names and the reference numbers is:
1-nut body, 2-guide hole, 3-chamfer, 4-threaded hole, 5-embossing tooth and 6-screw.
Detailed Description
As shown in figures 1 to 3:
the utility model provides a rivet pressing nut with direction, it includes that nut main part 1 is cylindrical nut, and 4 upper portions of the inside embedding screw hole that sets up of nut main part 1 are processed there is chamfer 3, and 3 upper portions of chamfer are processed there is columniform guiding hole 2, and 1 top of nut main part is provided with the annular boss of circle, and the external diameter periphery of boss is processed and is pressed knurling tooth 5.
Wherein, the guiding hole 2 is opened at the top of the nut body 1, the inner side wall of the guiding hole 2 is in threaded connection with the screw 6, the hardness of the riveting part of the threaded hole 4 and the screw 6 is more than HRC35, and the nut has the function of stabilizing components through the hardness of the threaded hole 4 and the screw 6.
Wherein, knurling tooth 5 is the cyclic annular sharp tooth of round evenly distributed, overcomes the easy not hard up defect of traditional pressure rivet nut, ensures the locking force of nut main part 1 and panel beating, effectively improves locking effect.
Wherein, the lower part of chamfer 3 is the inboard slope setting, the bottom external diameter of chamfer 3 is less than the external diameter of guiding hole 2, guiding hole 2 forms a taper shape with chamfer 3 whole, guiding hole 2 sets up with chamfer 3 as an organic whole, improve the centering nature of pressing nut main part 1 when installation screw 6 through guiding hole 2, when nut main part 1 is being connected with screw 6, play good guide effect, the screw can be put into the nut easily and fix a position, avoid damaging the nut when screwing up.
The working principle is as follows:
the nut main body 1 is circular in shape, one end of the nut main body is provided with the embossing teeth 5 and the guide hole 2, the principle is that the nut main body is pressed into the screw 6 on the metal plate through the embossing teeth 5, the aperture of the screw 6 on the metal plate is slightly smaller than the outer diameter of the embossing teeth 5 of the nut main body 1, the screw 6 on the metal plate is extruded into the threaded hole 4 through the guide hole 2 and the chamfer 3 through pressure and rotation, so that the locking effect is generated, the centering performance of the nut main body 1 when the screw 6 is installed is improved through the guide hole 2, a good guiding effect is achieved when the nut main body 1 is connected with the screw 6, the screw can be easily placed into the nut and positioned, and the nut is prevented from being damaged when being screwed.
