Description

Technical Field

[0001] The utility model belongs to the technical field of nuts, in particular to a combined adjusting nut. Background Art

[0002] A nut is a cap that is screwed together with a bolt or screw to fasten the parts. It is an essential component for all manufacturing machinery and is divided into several types according to the material, such as carbon steel, stainless steel, and non-ferrous metals (such as copper). When tightened, most of the nuts rely on the compression effect between the nut and the workpiece to prevent loosening. Existing nuts installed on vibrating workpieces are prone to loosening and deflection, resulting in poor fastening effect, making the nut fastening failure, and posing certain safety hazards. For this reason, we propose a combined adjusting nut. Utility Model Content

[0003] In view of the above situation, in order to overcome the defects of the existing technology, the utility model provides a combined adjusting nut, which effectively solves the problem that the existing nut is easily loosened and deflected when installed on a vibrating workpiece, resulting in poor fastening effect, making the nut fastening failure, and posing certain safety hazards.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a combined adjusting nut, comprising a first nut, a ring groove being provided on the top wall of the first nut, a pushing spring being provided on the bottom wall of the inner cavity of the ring groove, a pushing ring being provided on the top of the pushing spring, a second nut being provided on the top wall of the first nut, sliding grooves being provided on the left and right side walls of the first nut, pressing blocks being provided on the left and right sides of the outer wall of the pushing ring, and the first nut matching the second nut.

[0005] Preferably, the left and right side walls of the second nut are both provided with moving grooves, and the left and right sides of the top wall of the pressing block are both provided with limiting frames, and the limiting frames are arranged in an L-shape.

[0006] Preferably, a limiting sleeve is provided on the outer wall of the limiting frame, and the inner wall of the limiting sleeve matches the outer wall of the second nut.

[0007] Preferably, the bottom wall of the first nut is provided with an anti-slip gasket, and the bottom wall of the anti-slip gasket is evenly provided with anti-slip bumps.

[0008] Preferably, the first nut, the second nut, the pushing spring and the pushing ring are located on the same axis.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] 1. This combined adjusting nut, by providing a first nut, a pushing spring and a second nut, can be used to simultaneously apply thrusts in opposite directions to the first nut and the second nut, thereby tightening the first nut and the second nut on the bolt and preventing loosening that affects the tightening effect.

[0011] 2. The combined adjusting nut can be easily positioned on the second nut by arranging a limiting frame, a second nut and a first nut, thereby preventing the second nut from loosening and hindering subsequent installation, and aligning the internal threads of the second nut with the first nut for easy subsequent installation.

[0012] 3. The combined adjusting nut can make the first nut and the second nut rotate synchronously by arranging the limiting sleeve, the first nut and the second nut and so on, which is beneficial to the screw connection operation and improves the practicality of the device.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] Depend on Figure 1 、 Figure 2 and Figure 3The top of the pushing spring 101 is fixedly connected to the pushing ring 102, and the second nut 103 is pushed by the pushing ring 102. The top wall of the first nut 100 is movably connected to the second nut 103, and the second nut 103 cooperates with the first nut 100 to be tightly connected to the outer wall of the screw. The left and right side walls of the first nut 100 are provided with sliding grooves, which are convenient for limiting and guiding the movement of the pressing block 104. The left and right sides of the outer wall of the pushing ring 102 are fixedly connected to pressing blocks 104, which are convenient for pushing the pushing ring 102 to move, and the first nut 100 matches the second nut 103.

[0021] In this embodiment, when screwing, the first nut 100 is placed on the bolt, and the hexagonal sleeve is placed on the outer wall of the second nut 103. The pressing block 104 is pressed to drive the pushing ring 102 to move, and the pushing ring 102 is used to squeeze the pushing spring 101, so that the second nut 103 moves to the top wall of the first nut 100, and the hexagonal sleeve is placed on the outer wall of the first nut 100. The first nut 100 and the second nut 103 are driven by the hexagonal sleeve to rotate synchronously, so that the first nut 100 and the second nut 103 are screwed synchronously. After the fixing is completed, the hexagonal socket is removed, and the pushing ring 102 is pushed to move by the elastic force of the pushing spring 101, and the second nut 103 is pushed by the pushing ring 102. At the same time, the pushing spring 101 applies a reverse thrust to the first nut 100, thereby preventing the first nut 100 and the second nut 103 from loosening, and making it easy for the device to apply thrusts in opposite directions to the first nut 100 and the second nut 103 at the same time, so that the first nut 100 and the second nut 103 are tightened on the bolt to avoid loosening that affects the tightening effect.

[0022] The left and right side walls of the second nut 103 are provided with movable grooves, and the left and right sides of the top wall of the pressing block 104 are fixedly connected to the limiting frame 105. The limiting frame 105 is used to facilitate limiting the second nut 103. The limiting frame 105 can be fixed with bolts, which is convenient for disassembly, maintenance and replacement. The limiting frame 105 is set in an L shape.

[0023] In this embodiment: the movable groove is used to facilitate the limitation of the movement of the limit frame 105, and the limit frame 105 is used to facilitate the limitation and guidance of the movement of the second nut 103, so that the device can facilitate the limitation of the second nut 103, avoid the second nut 103 from loosening and being detrimental to subsequent installation, and make the second nut 103 aligned with the internal thread of the first nut 100 for subsequent installation.

[0024] The outer wall of the limiting frame 105 is fixedly connected to the limiting sleeve 106 , which facilitates the synchronous rotation of the first nut 100 and the second nut 103 . The inner wall of the limiting sleeve 106 matches the outer wall of the second nut 103 .

[0025] In this embodiment, the limiting sleeve 106 facilitates the sleeve connection between the first nut 100 and the second nut 103 , so that the first nut 100 and the second nut 103 can rotate synchronously, which is beneficial to the screw connection operation and improves the practicality of the device.

[0026] The bottom wall of the first nut 100 is fixedly connected with an anti-skid washer 107 , which increases friction and improves anti-skid performance. The bottom wall of the anti-skid washer 107 is evenly provided with anti-skid bumps.

[0027] In this embodiment, the anti-slip pad 107 is provided to facilitate anti-slip positioning against the component, thereby avoiding deflection and facilitating fastening operations.

[0028] The first nut 100 , the second nut 103 , the pushing spring 101 and the pushing ring 102 are located on the same axis.

[0029] In this embodiment, the spring 101 is located on the same axis to facilitate pushing, and the first nut 100 and the second nut 103 are pushed, so that the force is even, the tightening operation is facilitated, and loosening is avoided.
