Description

Technical Field

[0001] This utility model relates to the field of mechanical connection technology, and in particular to a bolt self-locking anti-slip buckle device. Background Technology

[0002] Bolts are one of the most commonly used components in mechanical connections. Under conditions such as vibration, impact, and temperature cycling, bolts are prone to loosening due to a decrease in friction between the threads, leading to connection failure and even equipment malfunctions or safety accidents.

[0003] A search revealed Chinese patent CN205244094U, which discloses a fastener, specifically a self-locking bolt. This patent provides the following technical solution: a self-locking bolt includes a screw and an operating handle connected to the screw. The outer circumference of the screw is threaded, and a locking plate is fitted at the connection between the screw and the operating handle. The inner ring of the locking plate is engaged with the thread, and its outer ring has at least one set of symmetrical locking blocks extending outwards from the locking plate. This technical solution provides a self-locking bolt that is anti-slip and provides a secure connection.

[0004] Based on the above search and existing technology, the findings were as follows:

[0005] Existing patented structures rely on threaded engagement, which carries the risk of wear and loosening; the locking method is passive and has limited anti-rotation capability; the installation structure and tools are limited, resulting in a narrow range of applications; and the economy and sustainability are poor, making it unsuitable for repeated use, thus having certain limitations. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model proposes a bolt self-locking anti-slip buckle device, which is a bolt anti-slip component with simple structure, convenient installation, strong adaptability and stable anti-loosening effect.

[0007] The technical solution to achieve the purpose of this utility model is as follows: a bolt self-locking anti-slip buckle device, comprising an H-beam and a connecting plate, wherein the connecting plate is disposed on both sides of the H-beam, and further comprising a limiting round steel and a connecting assembly:

[0008] The limiting round steel is fixedly installed on the inside of the H-beam;

[0009] The connecting assembly includes multiple threaded screws installed between the H-beam and the connecting plate.

[0010] Preferably, a bolt head is fixedly installed at one end of each screw, and a double nut is threadedly installed at the other end of each screw. A nut is fixedly installed on the side of the bolt head, and a magnetic strip is fixedly installed on the outer side of the limiting round steel.

[0011] Preferably, an anti-slip limiting card is fixedly installed on the top of the nut, and the top of the anti-slip limiting card has a V-shaped groove, one of which is engaged with the bottom of the limiting round steel.

[0012] Compared with existing technologies, the significant advantages of this invention are:

[0013] Firstly, this utility model utilizes the V-shaped groove on the anti-slip limiting card to engage with the limiting round steel, effectively restricting bolt rotation, and is especially suitable for single-sided reinforcement scenarios; the design allows for single-person operation and installation, the connection component structure is simplified, and assembly efficiency is significantly improved; during disassembly, only a screwdriver or other tool needs to be inserted into the pry slot of the V-shaped card groove, and upward force can easily pop the card open, achieving quick disassembly.

[0014] Secondly, the standard parts such as bolts of this utility model can be used in similar steel structure projects, which improves the turnover rate of spare parts and helps to save labor and material costs; the limiting round steel fixedly installed on the inside of the H-beam makes the buckle body almost integrally formed, reducing the cumbersome assembly of multiple components and making the manufacturing process relatively simple.

[0015] It solves the problems of existing patented structures that rely on threaded engagement, which poses risks of wear and loosening; passive locking methods with limited anti-rotation capabilities; limited installation structures and tools, resulting in a narrow range of applications; and poor economy and sustainability, making them unsuitable for repeated use.

[0023] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0024] This utility model provides an improved bolt self-locking anti-slip buckle device. The technical solution of this utility model is as follows:

[0025] Example 1

[0026] like Figures 1-2 As shown, a bolt self-locking anti-slip buckle device includes an H-beam 1 and a connecting plate 2. The connecting plate 2 is set on both sides of the H-beam 1 to improve construction efficiency and reduce safety hazards. It also includes a limiting round steel 4 and a connecting component 3.

[0027] The limiting round steel 4 is fixedly installed on the inside of the H-beam 1. The buckle body is integrally formed, eliminating the need for multiple component splicing and simplifying the manufacturing process.

[0028] The connecting assembly 3 includes multiple threaded screws 301 installed between the H-beam 1 and the connecting plate 2, which can be installed by a single person and greatly improves assembly efficiency.

[0029] Example 2:

[0030] Based on the bolt self-locking anti-slip buckle device provided in the first embodiment of this application, the second embodiment of this application proposes another bolt self-locking anti-slip buckle device. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0031] The second embodiment of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0032] like Figures 3-4 As shown, a bolt head 302 is fixedly installed at one end of each screw 301, and a double nut 304 is threadedly installed at the other end of each screw 301. A nut 303 is fixedly installed on the side of the bolt head 302, and a magnetic strip 401 is fixedly installed on the outer side of the limiting round steel 4. The bolts can be used interchangeably during the construction of similar steel structures, realizing the turnover rate of spare parts and saving labor and material costs.

[0033] Furthermore, an anti-slip limiting card 5 is fixedly installed on the top of the nut 303. The top of the anti-slip limiting card 5 has a V-shaped groove 501. One of the V-shaped grooves 501 is engaged with the bottom of the limiting round steel 4, and the limiting card is engaged with the bottom of the nut 303. Therefore, during the unilateral reinforcement, the bolt rotates, causing the limiting card on the nut 303 to engage with the limiting round steel 4, thus blocking and limiting the bolt to prevent slippage. When disassembling the V-shaped groove 501, a screwdriver can be inserted into the slot and applied upward force to pop the card open for quick disassembly.

[0034] The specific working method is as follows: First, confirm the positions of H-beam 1 and connecting plate 2; fix the limiting round steel 4 inside the H-beam 1; a magnetic strip 401 will also be installed on the outside of the limiting round steel 4 to assist in positioning or enhance the stability of temporary fixing; pass the screw 301 through the pre-set holes on the H-beam 1 and connecting plate 2 and make a threaded connection; at one end of the screw 301, the bolt head 302 is usually fixed; the other end is locked with a double nut 304 to ensure the firmness of the connection; at the top of the nut 303... The anti-slip limiting card 5 is installed on the part; the V-shaped groove 501 at the top of the card is the key, and it is necessary to ensure that one of the V-shaped grooves 501 is precisely engaged with the bottom of the limiting round steel 4; in this way, when the bolt tends to rotate due to external force, the card will be blocked by the limiting round steel 4, thereby achieving self-locking and preventing the bolt from slipping and loosening; when disassembly is required, a tool (such as a screwdriver) is inserted into the pry groove of the V-shaped groove 501 and upward force is applied to disengage the anti-slip limiting card 5 from the limiting round steel 4, thereby loosening the bolt.

[0035] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
