Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of screws, in particular to a novel anti-slip fixing screw. Background Art
[0002] Screws are a common fastener, widely used in machinery, electrical appliances and buildings. They are generally made of metal, cylindrical in shape, and have concave and convex grooves on the surface called threads. Due to different measurement units, the representation methods of various threads are also different. Combination screws are often used in parts that are fastened to workpieces. Combination screws are generally composed of screws and nuts.
[0003] When the existing combination screws are used to connect workpieces, the nut is easy to loosen, causing the nut to easily separate from the screw, affecting its tightness. Therefore, we have introduced a new type of anti-separation fixing screw. Utility Model Content

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A new type of anti-slip fixing screw comprises a connecting column and a nut, wherein the upper end of the connecting column is fixedly connected to a screw cover, the outer surface of the screw cover is provided with a plurality of anti-slip strips, the middle part of the upper end of the screw cover is provided with a hexagonal groove, the lower part of the outer surface of the connecting column is provided with an external thread, the lower inner part of the connecting column is provided with a movable groove, the rear groove wall of the movable groove is fixedly connected to a spring, the end of the spring away from the rear groove wall of the movable groove is fixedly connected to a limiting block, the middle part of the front end of the limiting block is fixedly connected to a limiting rod, the inner wall of the nut is provided with an internal thread, and the outer surface of the nut is provided with a plurality of through-limiting holes.
[0007] Preferably, the external thread at the lower portion of the outer surface of the connecting column is threadedly connected to the internal thread inside the nut.
[0008] Preferably, a plurality of the anti-slip strips are distributed in a ring array.
[0009] Preferably, the outer surface of the limit block is movably connected to the inner wall of the movable groove.
[0010] Preferably, the limiting rod is movably connected to the movable groove through insertion.
[0011] Preferably, one end of the limiting rod away from the limiting block is inserted and connected with the corresponding limiting hole.
[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] 1. By threading the external thread on the connecting column with the internal thread on the nut, when the nut is about to contact the limit rod, by pressing the limit rod, the limit rod squeezes the spring through the limit block, and the limit rod shrinks into the movable groove, and then the nut continues to be rotated, so that the limit rod pops out from the corresponding limit hole under the elastic force of the spring, which facilitates the connection between the screw and the nut, and can improve the connection tightness between the screw and the nut, prevent the nut from loosening, and prevent the nut from detaching from the screw;
[0014] 2. When the nut and the screw need to be disassembled and separated, the limit rod is pressed, the limit rod is retracted into the movable groove and the spring is squeezed through the limit block, and at the same time the limit rod is disengaged from the limit hole, and then the nut is rotated, so that the screw and the nut can be quickly separated.
