Description

Technical Field

[0001] This utility model relates to the field of electrical connection technology, specifically to a fast connection device with anti-loosening type, threaded and welded tabs, and black nickel plating. Background Technology

[0002] In modern industrial production and electronic equipment manufacturing, a device capable of rapid connection is needed to improve production efficiency and facilitate equipment installation, maintenance, and upgrades. Traditional connection methods such as welding and riveting, while providing strong connections, are cumbersome and time-consuming in scenarios requiring frequent disassembly or reassembly, failing to meet the requirements of rapid assembly. Rapid connection devices, on the other hand, can complete connection and separation in a short time, significantly improving work efficiency.

[0003] Existing technologies mainly rely on internal structures; for example, the thread engagement bears mechanical loads. When vibration, impact or high-frequency shaking occurs during equipment operation, the friction between the threads may not be sufficient to resist external forces, causing the connection to gradually loosen or even fall off. Furthermore, the connection device may displace when subjected to axial tension or radial shear force, leading to mechanical connection failure. Therefore, we propose an anti-loosening threaded fast connection device with welded tabs and black nickel plating. Utility Model Content

[0004] The purpose of this invention is to provide a fast-connecting device with anti-loosening thread and welding tabs, and black nickel plating, to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fast-connecting device with anti-loosening thread and welding tabs, black nickel-plated, comprising a connecting body, a sleeve disposed on the connecting body, and further comprising:

[0006] A reinforcing assembly includes a collar rotatably connected to a connecting body, an extension plate connected to the top of the collar, a connector connected to the extension plate, a limit ball connected to the connector, a connecting plate provided on the sleeve, a rotating shaft rotatably connected to the connecting plate, and a limit plate rotatably connected to the rotating shaft.

[0007] A connecting component, the connecting component including threads disposed on a connecting body, the connecting body having a threaded groove, the threads engaging with the threaded groove.

[0008] Furthermore, a spring-loaded assembly is provided on the side of the connecting plate near the limiting plate. The spring-loaded assembly includes a spring, and a support plate is connected to the top of the spring. The support plate is connected to the limiting plate.

[0009] The above technical solution is adopted: by setting a rebound component, when the limit ball is engaged in the two limit plates, the limit plates will automatically rebound and reset by the elastic force of the spring.

[0010] Furthermore, a fixing component is provided on the side of the sleeve near the connecting plate. The fixing component includes a clamping plate sleeved on the sleeve, and a bolt is threadedly connected between the clamping plate and the sleeve.

[0011] The above technical solution involves setting up a fixing component to connect the connecting plate and the sleeve.

[0012] Furthermore, a nylon anti-loosening ring is provided at the middle of the thread.

[0013] The above technical solution involves setting a nylon anti-loosening ring. When tightened, the nylon ring deforms and fills the thread gap, thus preventing loosening through frictional resistance.

[0014] Furthermore, a welding tab is provided at the end of the connecting body.

[0015] The above technical solution is adopted: by setting welding plates, energy is absorbed through deformation under mechanical start-up or impact load, thereby reducing the instantaneous peak force on the bolt.

[0016] Furthermore, the reinforcing component is provided with two sleeves, and the two reinforcing components are respectively located on both sides of the connecting body and the sleeve.

[0017] The above technical solution is adopted: by setting up the connection part, both the upper and lower sides are reinforced to improve stability.

[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0019] In this invention, by setting up reinforcing components, the stability of the connection is enhanced, preventing the connection from loosening and falling off due to vibration during equipment operation. This solves the problem in the prior art that mainly relies on internal structures; for example, the thread engagement bears mechanical loads, but when the equipment vibrates, impacts, or shakes at high frequencies during operation, the friction between the threads may not be sufficient to resist external forces, causing the connection to gradually loosen or even fall off. Furthermore, the connection device may displace under axial tension or radial shear force, leading to mechanical connection failure. Attached Figure Description

[0032] 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.

[0033] like Figures 1-5 As shown, this utility model provides a technical solution: a fast-connecting device with anti-loosening threaded strips and black nickel plating, comprising a connecting body 1, a sleeve 2 disposed on the connecting body 1, and further comprising:

[0034] The reinforcing component 3 includes a collar 31 rotatably connected to the connecting body 1, an extension plate 32 connected to the top of the collar 31, a connector 33 connected to the extension plate 32, a limit ball 34 connected to the connector 33, a connecting plate 35 provided on the sleeve 2, a rotating shaft 36 rotatably connected to the connecting plate 35, a limit plate 37 rotatably connected to the rotating shaft 36, and two sleeves 2 provided in the reinforcing component 3, with the two reinforcing components 3 located on the connecting body 1 and the sleeves 2 respectively on both sides;

[0035] Connection component 6 includes a thread 61 disposed on the connection body 1, and a threaded groove 62 is provided in the connection body 1, wherein the thread 61 and the threaded groove 62 are engaged and connected.

[0036] Specifically, when the connecting body 1 is screwed into the sleeve 2, it will drive the collar 31 and the top extension plate 32 to move. The extension plate 32 will drive the limiting ball 34 to move. When the limiting ball 34 touches the limiting plate 37, the limiting plate 37 will be squeezed to both sides by the limiting ball 34 through the rotating shaft 36. Then the limiting ball 34 will enter the gap between the two limiting plates 37 to lock and reinforce the connection.

[0037] Furthermore, such as Figure 1 As shown: A nylon anti-loosening ring 7 is provided at the middle of the thread 61, and a welding piece 8 is provided at the end of the connecting body 1. By setting the nylon anti-loosening ring 7, the nylon ring deforms and fills the thread gap when tightened, and the loosening is prevented by frictional resistance. By setting the welding piece 8, under mechanical start-up or impact load, the energy is absorbed by deformation, reducing the instantaneous peak force on the connecting body 1.

[0038] The above solution also has the problem that when the limiting plate 37 is squeezed to both sides, it cannot rebound, thus failing to engage and limit the limiting ball 34. Figure 3 As shown: A spring-loaded assembly 4 is provided on the side of the connecting plate 35 near the limiting plate 37. The spring-loaded assembly 4 includes a spring 41. A support plate 42 is connected to the top of the spring 41. The support plate 42 is connected to the limiting plate 37. When the limiting plate 37 is squeezed to both sides, the spring 41 will be squeezed and contracted simultaneously. When the limiting ball 34 moves to the gap in the middle of the limiting plate 37, and the limiting plate 37 does not receive the squeezing force, the elastic force after the spring 41 contracts will automatically spring the limiting plate 37 back to its original position and limit and lock the limiting ball 34.

[0039] The above solution also has the problem that the connecting plate 35 cannot be fixed to the sleeve 2, such as... Figure 2 As shown: A fixing component 5 is provided on the side of the sleeve 2 near the connecting plate 35. The fixing component 5 includes a clamping plate 51 sleeved on the sleeve 2. A bolt 52 is threaded between the clamping plate 51 and the sleeve 2. The fixing component 5 is used to connect the connecting plate 35 and the sleeve 2.

[0040] The working principle provided by this utility model is as follows: Figures 1-5As shown: First, the connecting body 1 is screwed so that the thread 61 on it engages with the threaded groove 62 on the inner wall of the sleeve 2, thereby connecting. During the connection process, the nylon anti-loosening ring 7 deforms and fills the thread gap, preventing loosening through frictional resistance. At the same time, the welding piece 8 absorbs energy through deformation, reducing the instantaneous peak force on the connecting body 1. During the movement of the connecting body 1, it will drive the collar 31 and the top extension plate 32 to move. The extension plate 32 will drive the limiting ball 34 to move. When the limiting ball 34 touches the limiting plate 37, the limiting plate 37 will be squeezed to both sides by the limiting ball 34 through the rotating shaft 36. During the process of the limiting plate 37 being squeezed to both sides, the spring 41 will be compressed and contracted simultaneously. When the limiting ball 34 moves to the gap in the middle of the limiting plate 37, and the limiting plate 37 does not receive the squeezing force, the elastic force of the spring 41 after contraction will automatically spring the limiting plate 37 back to its original position, limiting and locking the limiting ball 34, and reinforcing the connection part.

[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
