Description

Sleeve ring

The present invention relates to a sleeve ring, specifically a hand tool accessory, which can be used as a medium tool between a conventional sleeve and a screw or nut, and is especially suitable for dismantling a screw or nut that has broken or slipped. .

By the way, in today’s workplaces, there are many product combinations, all of which use a combination of bolts and nuts. Regardless of whether it is a hexagonal screw or a nut, the disassembly and assembly require the use of sockets or sleeve tools. No matter in construction, automobile maintenance or furniture assembly, it is often necessary to use sleeves to turn bolts, nuts or screws and other locking elements. Therefore, in various types of hand tools, sleeves It is one of the most frequently used hand tools.

According to the principle of mechanical component design, the nut is a replaceable consumable, and the sleeve is a necessary tool, so the hardness of the sleeve will far exceed that of the nut, and in order to make the sleeve smooth during use Fitting in or out of the nut, there is usually no tight fit between the two, but a gap is reserved. The gap is likely to cause sliding when the user applies force to lock or unload, so that the force will be transferred and concentrated on the screw. At the corner of the cap, and because the sleeve material is hard, after several rotations, the corner will be highly worn and rounded, and slipping will occur in the subsequent rotation, which will cause the screw The cap is difficult to be unscrewed again.

In view of this, how to develop and improve the shortcomings of the above-mentioned conventional sleeves is actually the goal of the relevant industry’s efforts to develop. In view of this, the creator has thought and creative ideas, and then used years of experience to develop The design, after many discussions and sample tests, and many revisions and improvements, is the present invention.

The present invention relates to a sleeve ring, which is an auxiliary accessory for hand tools, which can be used as an intermediary tool between a conventional sleeve and a screw or nut, and is particularly suitable for disassembling a screw or nut that has broken or slipped.

In order to achieve the foregoing creative purpose, the "sleeve ring" of the present invention includes a sleeve ring body. The outer periphery of the sleeve ring body has a hexagonal shape and a driving outer surface for the sleeve to be placed. The sleeve ring The inner edge of the body is provided with a drive port for the screw to be inserted into the sleeve. The inner edge of the drive port is a hexagonal drive inner side. Both sides of the drive port are defined as an entrance port and a restriction port. The drive port is It is tapered from the side of the inlet port to the side of the restriction port, and at least one restriction rib is formed on each of the six sides of the drive port on the inner side of the drive; In this way, when you want to remove a screw that has broken or slipped, you only need to place the sleeve ring body and the screw on the side of the entry port. The drive port is tapered so that the entry port is a relatively large diameter drive port. On the side, the sleeve ring body is provided for easy application of the screw. After the tapered restriction ribs conflict with the upper edge of the screw, continue to rotate or knock the sleeve ring body with a tool to force the restricting port section. It is sleeved on the screw, and the limiting rib on the inner side of the drive will be fixed to the outer diameter of the screw. The sleeve and sleeve ring body corresponding to the size of the outer side of the drive can be sleeved to remove the screw that is broken or slipping.

The aforementioned driving inner side surface is formed with two restriction ribs on each of the hexagonal surfaces, and each restriction rib has a shape from one end to the other end from wide to narrow, and its wider end corresponds to the restriction port, which is narrower The end system corresponds to the entry port side.

From the foregoing creation, it can be seen that the "sleeve ring" of the present invention can be applied to screw or nut that is broken or slipping. It is designed with a tapered drive port to easily fit the sleeve ring body to the deformed screw or nut. , And through the design that the inner diameter section is tapered from width to width, the sleeve ring body is finally pressed against the screw or nut that is broken or slipping, and the limiting ribs on the inner side of the drive have the effect of occlusal fixation. The sleeve that meets the specifications of the drive outer surface can be matched with it to rotate and remove the nut that has broken teeth and slipped; therefore, the present invention can be said to be a very practical and progressive creation, which is worthy of promotion in the industry. And make it public.

The present invention relates to a sleeve ring, which is an auxiliary accessory for hand tools, which can be used as an intermediary tool between a conventional sleeve and a screw or nut. It is especially suitable for disassembling a screw or nut that has broken or slipped. Please refer to As shown in the first to sixth figures, the "sleeve ring" of the present invention includes a sleeve ring body 1. The outer periphery of the sleeve ring body has a hexagonal shape and is provided with a drive outer surface for sleeve sleeves 11. The inner edge of the sleeve ring body 1 has a drive opening 12 for the screw 2 to pass through. The inner edge of the drive opening 12 is a hexagonal drive inner surface 121, and the hexagon is a corresponding sleeve and screw , The specification of the nut, the specification uses this as the representative of the implementation, and the actual application is not limited to this. The two sides of the drive port 12 are defined as an entry port A and a restriction port B. The drive port 12 is defined by the entry port The side A is tapered toward the side of the restriction port B, and the driving port 12 is formed with at least one restriction rib 122 on each of the six sides of the driving inner side 121; in this way, when you want to remove the screw that has broken or slipped When the sleeve ring body 1 and the screw 2 are sleeved on the side of the inlet port A, the drive port 12 is tapered so that the inlet port A is on the side of the drive port 12 with a relatively large diameter, providing a sleeve ring The main body 1 can be easily placed in the application of the screw 2. After the tapered limiting rib 122 conflicts with the upper edge of the screw 2 (as shown in the fourth figure), continue to tap the upper part of the sleeve ring main body 1 with a tool. Force the limiting port B section onto the screw 2, and the limiting rib 122 on the inner side of the drive 121 will bite the outer diameter of the screw 2 (as shown in the fifth and sixth figures), and continue to correspond to the size of the outer side of the drive 11 The sleeve and the sleeve ring body are set in one sleeve, and the screw that is broken or slipping can be rotated and removed.

Furthermore, the driving inner surface 121 is formed with two restriction ribs 122 on the hexagonal surface, and each restriction rib 122 has a shape from one end to the other end, and its wider end corresponds to Restricting the port B side, its narrower end corresponds to the entering port A side; so, The gap between the restricting ribs 122 is tapered from the entry port A side to the restricting port B side, which can further enhance the effectiveness of the sleeve ring body 1 for tightening the teeth and slipping the screws.
