Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical fastener technology, and in particular to an elastic washer integrated anti-loosening bolt. Background Technology
[0002] Bolts, as one of the most commonly used fasteners, are widely used in various mechanical connections. However, under dynamic conditions such as vibration, impact, or variable loads, traditional bolt-nut connections are prone to loosening due to minute relative movements between the threads, leading to a decrease in preload and even connection failure, thus creating safety hazards.
[0003] In existing integrated anti-loosening bolts with elastic washers, the elastic washers are prone to loosening and falling off, and are often separate units, making them inconvenient to assemble and use; moreover, the bolts are also prone to loosening even with the assistance of elastic washers, which makes the device somewhat inadequate. Utility Model Content

[0006] The limiting component includes a limiting rod, which is fixedly connected to the top of the elastic washer body. Multiple sets of the limiting rod are provided. A limiting groove is opened in the fixing ring, and multiple sets of the limiting groove are provided. The limiting rod is slidably connected in the fixing ring.
[0007] As a further description of the above technical solution:
[0008] The top of the limiting rod is fixedly connected to a limiting plate, which is located within the limiting groove.
[0009] As a further description of the above technical solution:
[0010] The protective component includes a fixed post, a groove is formed in the threaded rod body, a spring is fixedly connected to the top of the fixed post, the top of the spring is fixedly connected to the top of the groove, and a baffle is hinged to the outer wall of the fixed post, and multiple sets of baffles are provided.

[0016] The spring is provided in multiple sets.
[0017] As a further description of the above technical solution:
[0018] The fixing post is located within the groove.
[0019] This utility model has the following beneficial effects:
[0020] 1. In this utility model, the use of a limiting component makes it easy to integrate the elastic washer body onto the bolt, eliminating the need for separate matching and installation during assembly, thus making it more convenient to use.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Reference Figures 1-4 An embodiment of this utility model is provided: an elastic washer integrated anti-loosening bolt, including a bolt head 1 and an elastic washer body 6. A connecting rod 2 is fixedly connected to the bottom of the bolt head 1, and a threaded rod body 3 is fixedly connected to the bottom of the connecting rod 2. A fixing ring 4 is rotatably connected to the outer wall of the connecting rod 2. A limiting component is provided between the fixing ring 4 and the elastic washer body 6. A protective component is provided inside the bottom of the threaded rod body 3.
[0030] The limiting component includes a limiting rod 7, which is fixedly connected to the top of the elastic washer body 6. Multiple sets of limiting rods 7 are provided. A limiting groove 5 is opened in the fixing ring 4, and multiple sets of limiting grooves 5 are provided. The limiting rod 7 is slidably connected in the fixing ring 4.
[0031] A limiting plate 8 is fixedly connected to the top of the limiting rod 7, and the limiting plate 8 is located in the limiting groove 5; the protective component includes a fixed post 11, a groove 9 is opened in the threaded rod body 3, a spring 10 is fixedly connected to the top of the fixed post 11, and the top of the spring 10 is fixedly connected to the top of the groove 9; a baffle 12 is hinged to the outer wall of the fixed post 11, and multiple sets of baffles 12 are provided; an auxiliary groove 13 is opened on the outer wall of the fixed post 11, and multiple sets of auxiliary grooves 13 are provided to facilitate pulling out the fixed post 11; a soft pad 14 is fixedly connected to the bottom of the elastic washer body 6; multiple sets of springs 10 are provided; the fixed post 11 is located in the groove 9, and a short rod is fixedly connected to the top of the fixed post 11. The short rod slides in the threaded rod body 3, and a limiting block is provided at the top of the short rod to prevent the short rod from sliding out of the threaded rod body 3, thereby preventing the fixed post 11 from extending too far out of the groove 9.
[0032] Working principle: The elastic washer body 6 is integrated into the bolt, eliminating the need for separate matching and installation during assembly, making it more convenient to use. After the end of the threaded rod 3 away from the bolt head 1 is passed through the connected part and tightened, the elastic washer body 6 is squeezed when the connected part shakes. The elastic washer body 6 can buffer the shaking and squeeze the bolt head 1, making it less prone to loosening. At the same time, the limiting rod 7 slides in the fixing ring 4. Under the action of the limiting plate 8, the limiting rod 7 will not slip out of the fixing ring 4 and fall off. After one end of the threaded rod 3 passes through the connected part, the fixing post 11 is pulled out from the groove 9 on the other side of the connected part. The multiple sets of baffles 12 are rotated to a horizontal position and pressed against the outside of the end of the threaded rod 3 away from the bolt head 1. Under the action of the stretched spring 10, the stability of the baffle 12 at one end of the threaded rod 3 is increased, which facilitates secondary reinforcement and protection of the bolt. It can improve stability when penetrating and fixing objects, making it less prone to falling off.
