Description

TECHNICAL FIELD

[0001] The utility model relates to a pull rivet nut technical field, specifically related to a pull rivet nut convenient to use. BACKGROUND

[0002] The pull rivet nut is also called rivet nut or self-clinching nut, and is a new type of connecting product developed to solve the problems of easy melting of the welded nut of the metal sheet and thin pipe and easy slippage of the internal thread of the rivet nut. The pull rivet nut is widely used in the assembly of electromechanical and light industrial products such as automobiles, aviation, instruments, furniture and decoration.

[0003] When the common pull rivet nut is installed, the pull rivet nut is first placed in the pre-processed installation hole, then the gun nozzle of the pull rivet gun bites the head of the pull rivet nut, and the pull rivet nut is firmly fixed in the installation hole by applying the pulling force of the pull rivet gun, and then the threaded connecting piece such as a bolt is screwed into the threaded part of the pull rivet nut to realize the connection between the parts. In the installation process, if the inner wall of the installation hole is attached with sundries, it will affect the correct installation position of the pull rivet nut.

[0004] For example, the metal chips in the hole may cause the pull rivet nut to not be in the correct central position when placed in the installation hole, thereby causing tilting. When the tilted nut is installed in the hole, the connection is not firm and the wear is aggravated. UTILITY MODEL CONTENTS

[0025] The technical solutions in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model.

[0026] Please refer to Figs. 1-3The utility model discloses a pull rivet nut convenient to use, including head 1, the bottom of head 1 is integrally formed with cylindrical portion 2, the bottom of cylindrical portion 2 is integrally formed with threaded portion 3, the outside of threaded portion 3 is provided with annular distribution's recess 4, the inner wall of recess 4 is fixedly connected with elastic block 5, and one side of elastic block 5 is fixedly connected with cleaning block 6.

[0027] The utility model discloses, head 1, cylindrical portion 2 and threaded portion 3 constitute a complete pull rivet nut, when installing the pull rivet nut, threaded portion 3 first inserts into the mounting hole on the metal sheet, after threaded portion 3 enters the inside of the mounting hole, cleaning block 6 will contact with the surface of the metal sheet, at this moment, the user pushes the pull rivet nut and moves, and cleaning block 6 will be inserted into the mounting hole on the metal sheet, at this moment, elastic block 5 is in compression state, and cleaning block 6 will be tightly attached to the inner wall of the mounting hole on the metal sheet, at this moment, the user rotates the pull rivet nut, and threaded portion 3 on the pull rivet nut will drive cleaning block 6 to rotate along the inner wall of the mounting hole on the metal sheet, and cleaning block 6 will scrape off sundries attached to the inner wall of the mounting hole, and then realize the effect of cleaning the inner wall of the mounting hole, then the user inserts the pull rivet nut into the mounting hole with force until head 1 contacts with the surface of the metal sheet, and then completes the placement of the pull rivet nut, then can use the rivet gun to install the pull rivet nut on the metal sheet, since the inner wall of the mounting hole is cleaned, so the pull rivet nut can be placed in the center position of the mounting hole, and then avoid the inclination of the pull rivet nut, improve the practicability of the device.

[0028] Please refer to Fig. 1 With 2 Among them: the surface of cleaning block 6 is ground sand setting.
