Description

Technical Field

[0001] The utility model relates to the technical field of pressure riveting screws, in particular to a pressure riveting type spring screw with wing. Background Art

[0002] Compression rivet screws are a type of stud that is turned on a lathe. They are fasteners specifically used on sheet metal. They are generally made of stainless steel and carbon steel. They have a relatively strong structure and are securely fixed.

[0003] Existing self-clinching screws are divided into spring-type and non-spring-type. The spring-type self-clinching screw is also called a loose but not falling screw. It can be riveted on the iron plate and can be screwed in and out freely. The whole piece can be firmly embedded in the panel without being separated from the panel. It can also be used to install PCB boards and only takes up a small space. It is mainly composed of four parts: a hand-tightening sleeve, a screw, a spring, and a self-clinching sleeve. The function of the spring makes the whole part not fall out and is easy to stretch freely.

[0004] During the use of spring rivet screws, since they are simply locked by threads, after long-term use, the threads will loosen due to the locking device, causing safety problems. At the same time, the rivet sleeve and the hand-tightening sleeve in the surface connector are only connected by a spring, which is relatively loose and easy to shake left and right during use, affecting use.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1

[0023] See also Figure 1 and Figure 2 The figure shows a riveting type spring screw with wings, including a hand-tightening sleeve 1, a screw body 2 is fixedly installed on the bottom of the hand-tightening sleeve 1, a riveting sleeve 3 is sleeved on the outer side of the screw body 2, a spring body 4 is fixedly installed between the inner bottom wall of the riveting sleeve 3 and the hand-tightening sleeve 1, a slide groove 5 is provided on the outer side of the riveting sleeve 3, a slip ring 6 is slidably provided in the slide groove 5, a communicating through hole 7 is provided in the hand-tightening sleeve 1 and the screw body 2, a rotating column 8 is provided in the through hole 7, a mounting sleeve 10 is fixedly installed on the bottom of the screw body 2, and a limiting mechanism 9 connected to the rotating column 8 is provided in the mounting sleeve 10.

[0024] See also Figure 3 In the figure, the limiting mechanism 9 includes a bevel gear 1 901, a threaded column 902 and a bevel gear 2 903. The bottom of the rotating column 8 passes through the through hole 7 and is fixedly installed with the bevel gear 1 901. The threaded column 902 is rotatably installed on the inner side of the mounting sleeve 10, and the bevel gear 2 903 is fixedly installed on the outer side of the threaded column 902, and the bevel gear 2 903 is meshingly connected with the bevel gear 1 901.

[0025] In this embodiment, when the rotating column 8 is rotated, the bevel gear 1 901 drives the bevel gear 2 903 to rotate, and the bevel gear 2 903 drives the threaded column 902 to rotate.

[0026] See also Figure 3 In the figure, the limiting mechanism 9 also includes a sliding plate 904, a connecting groove 905 and a limiting plate 906. The outer side of the threaded column 902 is threadedly connected to the sliding plate 904. The bottom of the mounting sleeve 10 is provided with a connecting groove 905 connected to the inner side. The bottom of the sliding plate 904 passes through the connecting groove 905 and is fixedly installed with the limiting plate 906.

[0027] In this embodiment, when the threaded column 902 rotates, it drives the sliding plate 904 to move leftward, and drives the limiting plate 906 to move leftward to the left side of the installation sleeve 10, abutting against one side of the sheet metal part passing through, preventing the screw body 2 from being pulled out upward.

[0028] Working principle: Align the installation sleeve 10 in the device with the threaded hole in the sheet metal and insert it, grab and twist the rubber sleeve 16 to drive the hand-tightening sleeve 1 to rotate, so that the screw body 2 is slowly screwed into the threaded hole in the sheet metal. At this time, the lower side of the rivet sleeve 3 abuts on the sheet metal. As the screw body 2 descends, the rivet sleeve 3 moves upward vertically smoothly. When the installation sleeve 10 at the bottom of the screw body 2 passes through the threaded hole, a screwdriver can be used to insert into the cross slot 15, and the rotating disk 14 is rotated to drive the rotating column 8 to rotate. The bevel gear 1 901 on the outside of the rotating column 8 drives the bevel gear 2 903 to rotate, and further drives the threaded column 902 to rotate. The sliding plate 904 moves to the left, driving the limit plate 906 to move left to the left side of the installation sleeve 10, abutting against the side of the passed sheet metal, preventing the screw body 2 from being pulled out upward.

[0029] Example 2

[0030] See also Figure 4 This embodiment further explains Example 1. In the figure, a limiting groove 11 is opened on the inner side of the hand-tightening sleeve 1. A limiting disk 12 is movably arranged in the limiting groove 11. The limiting disk 12 is fixedly installed on the outer side of the rotating column 8.

[0031] In this embodiment, the limiting plate 12 rotates in the limiting groove 11 , thereby limiting the rotation column 8 from being pulled outward.

[0032] See also Figure 4 In the figure, a groove 13 is provided on the upper side of the hand-tightening sleeve 1, a rotating disk 14 is arranged in the groove 13, the top of the rotating column 8 is fixedly mounted on the bottom side of the rotating disk 14, and a cross groove 15 is provided on the upper end of the rotating disk 14.

[0033] In this embodiment, a screwdriver is inserted into the cross slot 15 to rotate the rotating disk 14, thereby driving the rotating column 8 to rotate.

[0034] See also Figure 1In the figure, a rubber sleeve 16 is fixedly installed on the outer side of the hand-tightening sleeve 1, and the outer side of the rubber sleeve 16 is provided with anti-slip patterns in the up and down directions.

[0035] In this embodiment, the rubber sleeve 16 is grasped and twisted, so as to facilitate screwing the screw body 2 into or out of the threaded hole of the sheet metal part.

[0036] See also Figure 2 In the figure, a receiving ring 17 is fixedly installed on the outer side of the bottom of the hand-tightening sleeve 1, and the outer side of the slip ring 6 is fixedly installed on the inner bottom side of the receiving ring 17.
