Description

Technical Field

[0001] The utility model relates to the technical field of fasteners, in particular to a nut which is easy to disassemble. Background Art

[0002] A nut, also known as a cap, is a part that is screwed together with a bolt or screw to fasten it. Nuts are widely used and can be found in many different industries and applications; for example, in automotive manufacturing, nuts are used to connect wheels and other parts; in the construction industry, nuts are used to connect steel structures and other building materials; and in machinery manufacturing, nuts are used to connect various parts of a machine. When nuts are used on some special equipment, such as construction machinery, the working environment of these equipment is relatively harsh and they are often constructed in rainy weather. This causes the connection between the nut and the bolt to be severely corroded. When a problem occurs with the equipment and the nut needs to be removed for repair, workers generally use a wrench to clamp the nut and then use a tool such as a hammer to hit the wrench to remove the nut.

[0003] Regarding the above-mentioned related technologies, the inventors found that when using a tool such as a hammer to hit the wrench to remove the nut, the hexagonal boss on the nut is easily damaged and cannot be reused. Repeated hitting of the wrench increases the difficulty of operation and reduces work efficiency. Utility Model Content

[0004] The main technical problem solved by the utility model is to provide a nut which is easy to disassemble, thereby reducing damage to the nut during disassembly, reducing the difficulty of operation and improving work efficiency.

[0005] In order to solve the above technical problems, a technical solution adopted by the present invention is: to provide a nut that is easy to disassemble, including: a nut body, a circular groove is concentrically provided at one end of the nut body, a plurality of circular holes are provided in an annular array in the circular groove, blind holes are respectively provided in the circular holes, annular lubricating oil bags are respectively provided in the blind holes, the inner holes of the annular lubricating oil bags are respectively penetrated by pull-type extrusion rod assemblies, which are suitable for squeezing the annular lubricating oil bags to leak lubricating oil, annular plates are detachably connected in the circular groove, and the annular plates are respectively connected to the outer ends of the pull-type extrusion rod assemblies, and the nut body is provided with oil flow channels equal to the number of blind holes and connected, and the oil flow channels are connected to the threaded holes of the nut body.

[0006] By adopting the above technical solution, during the process of disassembling the nut, when the connection area between the nut and the bolt is severely corroded, the operating annular plate is moved outward, and the annular plate drives the pull-type extrusion rod assembly to move, and the pull-type extrusion rod assembly squeezes the annular lubricating oil bag and destroys it, and the lubricating oil in the annular lubricating oil bag flows out, and the pull-type extrusion rod assembly continues to move to squeeze the lubricating oil, and the lubricating oil enters the internal thread gap of the nut body through the oil flow channel, thereby reducing the rotational resistance between the nut body and the bolt, and it is easy to disassemble the nut body using a wrench sleeve on the nut body, reducing the damage to the nut during disassembly, reducing the difficulty of operation, and improving work efficiency.

[0007] In a preferred example, the present invention can be further configured as follows: the pull-type extrusion rod assembly includes a circular pull rod and an extrusion plate connected to one end thereof, the other end of the circular pull rod is sleeved with a limiting ring, the limiting ring is slidingly connected to the circular pull rod, the end of the circular pull rod close to the limiting ring is connected to the annular plate, and the limiting ring and the circular hole are connected by a fastening glue.

[0008] By adopting the above technical solution, when the circular pull rod moves outward, the circular pull rod drives the extrusion plate to squeeze the annular lubricating oil bag, and the annular lubricating oil bag is destroyed by the greater pressure, causing the lubricating oil to flow out.

[0009] In a preferred example, the present invention can be further configured as follows: a plurality of tapered needles are connected at intervals to the end surface of the extrusion plate close to the annular lubricating oil bag.

[0010] By adopting the above technical solution and using the conical needle, the annular lubricating oil bag can be easily punctured to allow the lubricating oil to flow out.

[0011] In a preferred example, the present invention can be further configured as follows: the oil flow channel includes a plurality of through holes spaced apart on the nut body, the through holes are respectively connected to the blind hole and the internal threaded hole of the nut body, and the inner cavity of the through hole near the outer surface of the nut body is threadedly connected with a blocking screw.

[0012] By adopting the above technical solution, since the oil flow channel is arranged at intervals by several through holes, and the blind hole is connected to the internal threaded hole of the nut body through the through hole, and the internal thread of the through hole is connected with a sealing screw, the lubricating oil can flow into the internal thread gap of the nut body when squeezed by the pull-type extrusion rod assembly.

[0013] In a preferred example, the present invention can be further configured as follows: a plurality of locking screws are provided in an annular array on the annular plate, and the locking screws are threadedly connected to the nut body.

[0014] By adopting the above technical solution, the annular plate is connected to the nut body through the locking screw, which improves the convenience of installation and disassembly.

[0015] In a preferred example, the present invention can be further configured as follows: two arc-shaped handles are symmetrically connected to the annular plate.

[0016] By adopting the above technical solution, fingers pull the arc-shaped handle to move outward, so that the pull-type squeezing rod assembly squeezes the annular lubricating oil bag, thereby improving the convenience of operation.

[0017] In summary, the present invention has at least one of the following beneficial technical effects:

[0018] When the circular pull rod is operated to move outward, the circular pull rod drives the extrusion plate to squeeze the annular lubricating oil bag. The annular lubricating oil bag is destroyed by the greater pressure, causing the lubricating oil to flow out. The lubricating oil is squeezed through the oil flow channel and flows into the internal thread gap of the nut body, reducing the friction between the nut body and the bolt, that is, reducing the damage to the nut during disassembly, reducing the difficulty of operation, and improving work efficiency.
