Description

Technical Field

[0001] The utility model relates to the field of high-head knurled nuts, in particular to anti-skid high-head knurled nuts for a micro injection molding machine bracket. Background Art

[0002] As we all know, knurled nuts are useful nuts with knurled designs on the surface. The main advantage of knurled nuts is that they can be easily tightened by bare hand strength, and the nut can also be fixed to the handle or cover. This type of nut is most common in applications that do not require permanent placement, such as micro injection molding machine brackets. The use of knurled nuts helps to improve the ease of disassembly and reduce the possibility of over-tightening. You may not even need any tools to manipulate the fastener. However, when the knurled nut is in use, the pattern structure on the outer surface of the nut is easily worn. After the pattern is worn, the outer surface of the nut is smooth, which causes slipping when turning the nut, which is very inconvenient.

[0003] In response to the above problem, China Patent Publication No.: CN205744823U discloses a knurled nut. When a user rotates the knurled nut, the user first contacts the first raised portion on the outside. The first raised portion wears during use, and the edge of the raised strip becomes thinner after wear, exposing the second raised portion. The user contacts the second raised portion, which also has friction, thereby preventing the user from slipping when rotating the knurled nut and increasing the service life of the knurled nut.

[0004] Although the comparative patent solves the problem that the pattern structure on the outer surface of the nut is easy to wear, and the outer surface of the nut becomes smooth after the pattern is worn, resulting in slipping when the nut is turned, the device is relatively small when used on the bracket of a micro injection molding machine. During disassembly, the staff does not have enough space to twist the outer wall of the nut, which makes it difficult for the staff to apply force to the nut during disassembly and assembly, thereby greatly increasing the difficulty of using the knurled nut.

[0005] With respect to the above-mentioned related technologies, the device has the defect that it is difficult for the staff to apply force to the nut during disassembly and assembly, thereby greatly increasing the difficulty of using the knurled nut. Utility Model Content

Since there are two rotating plates, the protruding ends of the two rotating plates can be used to control the rotation of the nut, and the staff can more conveniently apply force to the nut during disassembly and assembly, thereby greatly reducing the difficulty of using the knurled nut.

[0011] As a preferred technical solution of the utility model, the shape of the accommodation groove is an arc structure, the shape of the rotating plate is the same as the shape of the accommodation groove, the outer wall of the rotating plate is slidably connected to the inner wall of the accommodation groove, and the rotation of the nut can be controlled by setting the rotating plate.

[0012] As a preferred technical solution of the utility model, one end of the moving block passes through the groove and extends to the inside of the placement groove, and the outer wall of the moving block is slidably connected to the inner wall of the groove.

[0018] 1. By providing the nut, the mounting groove, the rotating plate and the second magnetic block, when the staff finds it difficult to apply force to the nut during disassembly and assembly, the pull plate is pushed to separate the second magnetic block from the first magnetic block, so that the rotating plate is no longer positioned by the magnetic force, and the elastic force of the second spring will pop one end of the rotating plate out of the mounting groove, so that the rotating plate is more protruding with respect to the top of the nut. Since there are two rotating plates, the protruding ends of the two rotating plates can be used to control the rotation of the nut. The staff can more conveniently apply force to the nut during disassembly and assembly, thereby greatly reducing the difficulty of using the knurled nut.

[0019] 2. By providing the nut, knurled convex surface, raised particles and screw grooves, when it is necessary to pinch the knurled convex surface of the nut to control the rotation of the nut, the raised particles can increase the friction between the hand and the knurled convex surface, and the anti-slip layer can play an anti-slip role, thereby making it more convenient to control the rotation of the nut, thereby further meeting the use requirements of the device, and is therefore worthy of promotion.

[0029] The outer wall of the rotating plate 7 is fixedly connected to the first magnetic block 8, the inner wall of the accommodating groove 5 is provided with a groove 9, the inner wall of the groove 9 is fixedly connected to the first spring 10, one end of the first spring 10 is fixedly connected to a moving block 11, one end of the moving block 11 is fixedly connected to a second magnetic block 12, the top of the moving block 11 is fixedly connected to a moving rod 13, and the top of the moving rod 13 is fixedly connected to a pull plate 14.

[0030] The shape of the seating groove 5 is an arc structure, and the shape of the rotating plate 7 is the same as the seating groove 5. The outer wall of the rotating plate 7 is slidably connected to the inner wall of the seating groove 5. When it is difficult for the staff to apply force to the nut 1 during disassembly and assembly, the two rotating plates 7 can be used to control the rotation of the nut 1.

[0031] One end of the moving block 11 passes through the groove 9 and extends to the inside of the placement groove 5, and the outer wall of the moving block 11 is slidably connected to the inner wall of the groove 9. The moving block 11 can be moved to the inside of the groove 9 under the force, and then can drive the second magnetic block 12 to move to the inside of the groove 9.

[0032] The second magnetic block 12 and the first magnetic block 8 attract each other. The magnetic force of the second magnetic block 12 and the first magnetic block 8 can play a role in positioning the rotating plate 7, and the rotating plate 7 will be limited inside the accommodating groove 5.

[0033] A channel 15 is provided on the inner top wall of the groove 9, and the moving rod 13 is slidably connected to the channel 15. One side of the pull plate 14 is slidably connected to the top of the nut 1. The pull plate 14 is moved, thereby driving the movement of the channel 15 under the moving rod 13, so that the moving rod 13 drives the moving block 11 and the second magnetic block 12 to move into the groove 9, and then the movement of the moving block 11 can be controlled by the outside of the nut 1.

[0034] During use, when the staff finds it difficult to apply force to the nut 1 during disassembly and assembly, they push the pull plate 14, thereby driving the internal movement of the channel 15 under the moving rod 13, so that the moving rod 13 drives the moving block 11 and the second magnetic block 12 to move into the interior of the groove 9, thereby allowing the second magnetic block 12 to disengage from the first magnetic block 8, and then the rotating plate 7 is no longer positioned by the magnetic force, and the second spring 16 is in a compressed state, and then the elastic force of the second spring 16 will pop one end of the rotating plate 7 out of the placement groove 5, and then the rotating plate 7 is relatively protruding with respect to the top of the nut 1. Since there are two rotating plates 7, the protruding ends of the two rotating plates 7 can be used to control the rotation of the nut 1.
