Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, and in particular to a bearing plate with uniform pressure distribution in ring groove rivet riveting. Background Technology

[0002] In the field of modern industrial manufacturing, grooved rivets are widely used in industries with extremely high requirements for connection strength, such as aerospace, automobile manufacturing, and rail transportation, due to their efficient and reliable connection performance. Among them, the pressure-bearing plate with uniform pressure distribution is a key component of the grooved rivet riveting system. By uniformly transmitting the riveting pressure to the connected parts, it can effectively improve the overall performance of the connection structure and become an important technical means to ensure the stable operation of equipment.

[0003] The existing technology of riveting load-bearing plates with ring grooves still has certain limitations. The traditional load-bearing plate structure design is simple and cannot meet the connection requirements of complex shaped components or diverse load conditions, resulting in insufficient connection strength or local stress concentration, which seriously affects the service life of the structure. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a bearing plate with uniformly distributed riveting pressure of ring groove rivets, which aims to improve the problem that traditional bearing plate structures cannot meet the connection requirements of complex-shaped components or diverse load conditions.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The annular groove rivet provides uniform pressure distribution on the load-bearing plate, which includes a first fixing plate. The outer wall of the first fixing plate has a circular hole, and a screw is installed inside the circular hole. A washer is installed on the outer wall of the screw, and a bolt is threaded onto the outer wall of the screw. A second fixing plate is installed on the outer wall of the first fixing plate, and a clamping rod is fixedly connected to the outer wall of the second fixing plate. The outer wall of the clamping rod is located inside the second fixing plate, and an assembly is installed inside the second fixing plate.

[0007] Preferably, the assembly includes a sliding buckle, the outer wall of which is slidably connected to the outer wall of the second fixed plate, a first connecting plate fixedly connected to the outer wall of the sliding buckle, the outer wall of the first connecting plate slidably connected to the interior of the second fixed plate, a first sliding rod fixedly connected to the interior of the first connecting plate, the outer wall of the first sliding rod slidably connected to the interior of the second fixed plate, a spring provided on the upper surface of the first connecting plate, the top end of the spring being located inside the second fixed plate, a locking tooth fixedly connected to the lower surface of the first sliding rod, the outer wall of the locking tooth slidably connected to the interior of the second fixed plate, and the tooth tip engaging with the outer wall of the locking rod.

[0008] This utility model has the following beneficial effects:

[0009] In this invention, by pushing the first fixing plate, the locking rod enters the second fixing plate. The locking rod pushes the locking teeth to slide, and the locking teeth push a connecting plate to slide, causing the spring to contract. When the locking rod slides completely to the second fixing plate, the spring releases its elastic force to push the locking teeth to lock the locking rod, thereby reducing the risk of component breakage due to stress concentration and enhancing the reliability of the connection.

Detailed Implementation

[0017] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] Reference Figures 1-3An embodiment of this utility model provides a bearing plate with uniformly distributed riveting pressure of annular groove rivets, including a first fixing plate 1. The outer wall of the first fixing plate 1 has a circular hole 2. A screw 3 is disposed inside the circular hole 2. A washer 4 is disposed on the outer wall of the screw 3. A bolt 5 is threadedly connected to the outer wall of the screw 3. A second fixing plate 6 is disposed on the outer wall of the first fixing plate 1. A clamping rod 15 is fixedly connected to the outer wall of the second fixing plate 6. The outer wall of the clamping rod 15 is disposed inside the second fixing plate 6. A combination assembly 7 is disposed inside the second fixing plate 6.

[0019] Specifically, screws 3 and washers 4 are used to cooperate with bolts 5 to achieve uniform pressure distribution on the load-bearing plate. The outer wall of the first fixing plate 1 has a groove into which a clamping rod 15 slides. The outer wall of the clamping rod 15 has a groove for cooperating with the assembly 7 to splice the load-bearing plate. The clamping rod 15 is used to connect the first fixing plate 1 and the second fixing plate 6. The assembly 7 is used to fix the first fixing plate 1 and the second fixing plate 6, thereby improving the overall connection strength and stability of the load-bearing plate and extending its service life.

[0020] Reference Figures 3-4 The assembly 7 includes a sliding buckle 701, the outer wall of which is slidably connected to the outer wall of the second fixing plate 6. A first connecting plate 702 is fixedly connected to the outer wall of the sliding buckle 701. The outer wall of the first connecting plate 702 is slidably connected to the interior of the second fixing plate 6. A first sliding rod 703 is fixedly connected to the interior of the first connecting plate 702. The outer wall of the first sliding rod 703 is slidably connected to the interior of the second fixing plate 6. A spring 704 is provided on the upper surface of the first connecting plate 702. The top end of the spring 704 is located inside the second fixing plate 6. A locking tooth 705 is fixedly connected to the lower surface of the first sliding rod 703. The outer wall of the locking tooth 705 is slidably connected to the interior of the second fixing plate 6. The tooth end of the locking tooth 705 is engaged with the outer wall of the locking rod 15.

[0021] Specifically, the tooth end of the locking tooth 705 has a groove for locking the locking rod 15. The locking rod 15 slides into the second fixed plate 6, and the locking rod 15 pushes the locking tooth 705 to slide upward. The locking tooth 705 pushes the first sliding rod 703 to slide, and the first sliding rod 703 pushes the first connecting plate 702 to slide, causing the spring 704 to contract. When the locking rod 15 slides completely into the second fixed plate 6, the spring 704 releases its elastic force, causing the first connecting plate 702 to slide downward. The first connecting plate 702 drives the first sliding rod 703 to slide, and the first sliding rod 703 pushes the locking tooth 705 to lock the locking rod 15, thereby achieving the effect of flexibly adjusting the load-bearing plate structure according to actual engineering needs.

[0022] Working principle: When using this device, pushing the first fixed plate 1 causes the locking rod 15 to enter the second fixed plate 6, thereby the locking rod 15 pushes the locking tooth 705 to slide upward, and then the locking tooth 705 pushes the first sliding rod 703 to slide upward within the second fixed plate 6. Furthermore, the first sliding rod 703 drives the first connecting plate 702 to slide, thereby the first connecting plate 702 pushes the spring 704 to retract, and then the locking rod 15 slides completely to the second fixed plate 6. Furthermore, the spring 704 releases its elastic force to push the first connecting plate 702 to slide downward, thereby the first connecting plate 702 drives the first sliding rod 703 to slide, and then the first sliding rod 703 pushes the locking tooth 705 to lock the locking rod 15, thereby reducing the risk of breakage of the load-bearing plate due to stress concentration and enhancing the reliability of the connection part.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
