Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of spring washers, in particular to a spiral spring washer for bolts and nuts. Background Technique
[0002] Spring washers are widely used in the load-bearing and non-load-bearing structures of general mechanical products. They are characterized by low cost and convenient installation, and are suitable for parts with frequent installation and disassembly. Spring washers can play the functions of preventing loosening and increasing the pre-tightening force, while flat washers do not have this function. It can be used to increase the fastening contact area, prevent the friction between the bolt and the workpiece, and protect the surface of the connecting parts to prevent the workpiece surface from being scratched when the bolt and nut are tightened.
[0003] However, most of the existing spring washers are of a single structure. When the washers are stacked and used, relative displacement is likely to occur between the washers, which is not convenient for positioning and installation.
[0004] Therefore, in view of this, in view of the existing structural deficiencies, research and improvement are carried out, and a spiral spring washer for bolts and nuts is proposed. Content of the Utility Model
[0005] The purpose of the utility model is to provide a spiral spring washer for bolts and nuts to solve the problems put forward in the above background technique.
[0006] To achieve the above purpose, the utility model provides the following technical scheme: a spiral spring washer for bolts and nuts, including a washer body, a first rounded corner is arranged on the upper side of the inner circular surface of the washer body, a second rounded corner is arranged on the lower side of the inner circular surface of the washer body, a limiting card slot is opened on the upper surface of the washer body, and a limiting card block is fixedly connected to the lower surface of the washer body.
[0007] Preferably, the number of the limiting card slots is eight, and they are evenly distributed on the upper surface of the washer body.
[0008] Preferably, the number of the limiting card blocks is eight, and they are evenly distributed on the lower surface of the washer body.
[0009] Preferably, a first upturned corner is fixedly connected to the upper side of the left end of the washer body, and a first chamfer is arranged on the lower side of the left end of the washer body.
[0010] Preferably, a second chamfer is arranged on the upper side of the right end of the washer body, and a second upturned corner is arranged on the lower side of the right end of the washer body.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] 1. The present utility model can produce a good limiting effect through the settings of the washer body, the first rounded corner, the second rounded corner, the limiting slot and the limiting block, and can prevent relative displacement between the washer bodies.
[0013] 2. Through the settings of the first warped corner, the first chamfer, the second chamfer and the second warped corner, the first warped corner and the second warped corner can undergo elastic deformation after being extruded by the nut, enhancing the elastic effect. When the washer bodies are stacked, the first chamfer and the second chamfer can fit on the first warped corner and the second warped corner, and this design can prevent obstruction between the washer bodies. BRIEF DESCRIPTION OF THE DRAWINGS
[0014] Figure 1 is a schematic three-dimensional structure diagram of the whole of the present utility model;
[0015] Figure 2 is of the present utility model Figure 1 is a schematic bottom three-dimensional structure diagram.
[0016] In the figure: 1. washer body; 2. first rounded corner; 21. second rounded corner; 3. limiting slot; 4. limiting block; 5. first warped corner; 6. first chamfer; 7. second chamfer; 8. second warped corner. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0018] As Figure 1 - Figure 2 shown, a helical spring washer for a bolt and a nut includes a washer body 1. A first rounded corner 2 is provided on the upper side of the inner circular surface of the washer body 1, a second rounded corner 21 is provided on the lower side of the inner circular surface of the washer body 1. A limiting slot 3 is opened on the upper surface of the washer body 1, and a limiting block 4 is fixedly connected to the lower surface of the washer body 1. The number of the limiting slots 3 is eight and they are evenly distributed on the upper surface of the washer body 1. The number of the limiting blocks 4 is eight and they are evenly distributed on the lower surface of the washer body 1.
[0019] By adopting the above technical solution, the first rounded corner 2 and the second rounded corner 21 on the inner surface of the washer body 1 can facilitate the sleeving of the washer body 1 on the bolt. According to requirements, the stacking quantity of the washer bodies 1 can be increased or decreased. When stacking the washer bodies 1, the limiting block 4 can be clamped in the limiting slot 3, and this design can produce a good limiting effect and prevent relative displacement between the washer bodies 1.
[0020] AsFigure 1 and Figure 2 As shown in Figure 2 , a first warped corner 5 is fixedly connected to the upper side of the left end of the washer body 1, and a first chamfer 6 is provided on the lower side of the left end of the washer body 1.
[0021] Furthermore, a second chamfer 7 is provided on the upper side of the right end of the washer body 1, and a second warped corner 8 is provided on the lower side of the right end of the washer body 1.
[0022] Working principle: When using this helical spring washer for bolts and nuts, first, the first rounded corner 2 and the second rounded corner 21 on the inner surface of the washer body 1 can facilitate sleeving the washer body 1 on the bolt. The stacking quantity of the washer body 1 can be increased or decreased according to requirements. When stacking the washer bodies 1, the limit catch block 4 can be snapped into the limit card slot 3. The first warped corner 5 and the second warped corner 8 can undergo elastic deformation after being squeezed by the nut, enhancing the elastic effect. The first chamfer 6 and the second chamfer 7 can fit on the first warped corner 5 and the second warped corner 8 when the washer bodies 1 are stacked. This is the working principle of this helical spring washer for bolts and nuts.
