Description

Technical Field

[0001] This utility model relates to the field of automotive safety components technology, specifically to a quick-locking connector for hot-dip galvanized steel beams. Background Technology

[0002] In steel structure buildings, reliable connections between steel beams are crucial. Traditional connection methods mainly involve welding or high-strength bolts. Welding presents challenges such as difficult on-site construction, the creation of a heat-affected zone that degrades material properties, and severe damage to the hot-dip galvanized layer. Bolted connections require precise drilling and alignment, making the process cumbersome and inefficient.

[0003] To overcome the aforementioned problems, some mechanical quick-connect structures have gradually emerged in the market, such as beam clamps using U-bolts or Hollo-Bolt safety clips. These quick-connect components simplify the construction process to some extent, improve installation efficiency, and avoid damage to the galvanized layer caused by hot work. However, existing quick-connect components have relatively limited functionality and generally lack effective means of monitoring the connection status. In actual use, due to factors such as long-term loads, vibrations, or accidental impacts, the connection may loosen or experience stress concentration, and existing technologies cannot detect these problems in a timely manner, thus creating potential safety hazards. Utility Model Content

[0004] The present invention aims to solve the problems of limited functionality and low installation efficiency mentioned in the background art, and provides a quick-locking connector for hot-dip galvanized steel beams that is multifunctional and has high installation efficiency.

[0005] A quick-locking connector for hot-dip galvanized steel beams includes a locking body with a U-shaped insertion groove on the locking body and a through hole on the side wall of the insertion groove. At least one locking slider that can move radially is installed in the through hole. An eccentric mechanism is installed on the outer side of the locking body, and a monitoring module is integrated on the top of the locking body.

[0006] By setting up insertion slots, rapid insertion installation of steel beams is achieved, greatly improving construction efficiency; the radially movable locking slider provides active and adjustable locking force, ensuring the firmness and reliability of the connection, avoiding the complex procedures and heat-affected zone problems caused by traditional bolt connections or welding; the eccentric mechanism provides a labor-saving and efficient locking force driving method; the integrated monitoring module enables real-time and remote monitoring of the stress state of the connectors, providing data support for structural health monitoring and preventive maintenance, realizing intelligent management, and achieving the goal of diverse functions and high installation efficiency.

[0007] Preferably, the eccentric mechanism includes an eccentric wheel shaft and a cam portion. The eccentric wheel shaft is rotatably mounted on the outside of the locking body. The cam portion protrudes outward and contacts the outer side of the locking slider. A flexible anti-slip pad is adhered to the inner side of the locking slider. The structure of the eccentric wheel shaft and cam portion is simple and reliable. Utilizing the eccentric characteristic of the cam, a huge radial locking force can be generated with only a small angle rotation of the eccentric wheel shaft, making operation labor-saving and convenient. The flexible anti-slip pad increases the friction with the surface of the hot-dip galvanized steel beam, preventing slippage. On the other hand, it avoids hard scratches on the galvanized layer of the steel beam surface, maintaining its anti-corrosion performance.

[0008] Preferably, the flexible anti-slip mat is made of a high-molecular elastic material, and the surface of the flexible anti-slip mat is processed with intersecting diamond-shaped anti-slip patterns. High-molecular elastic materials (such as polyurethane or rubber) have good elasticity, wear resistance, and anti-aging properties, enabling long-term stable operation; the anti-slip patterns further increase static friction and prevent micro-slippage.

[0009] Preferably, the inner wall of the insertion groove of the latch body is provided with a positioning reference surface, and the outer surface of the latch body is coated with a nano-ceramic coating with a thickness of 0.1mm to 0.2mm. The latch body is made of high-strength alloy. The positioning reference surface ensures that the steel beam has the correct position and angle after insertion; the nano-ceramic coating has excellent corrosion resistance and wear resistance, and can effectively resist the erosion of the latch body by the external environment; the latch body is the core component of the entire connector, made of high-strength alloy material, and has excellent mechanical properties and fatigue resistance.

[0010] Preferably, an anti-loosening component is installed at the eccentric wheel shaft position on the locking body. The anti-loosening component includes a resiliently resettable stop pin, and a groove matching the stop pin is provided on the side of the cam portion. The resiliently resettable stop pin is pushed by a spring installed in a blind hole. Through the cooperation of the stop pin and the groove, it can be automatically or manually locked after the cam portion rotates to the locking position, effectively preventing accidental reverse rotation and loosening of the eccentric wheel shaft due to vibration or long-term load, and improving the long-term safety and reliability of the connection.

[0011] Preferably, the monitoring module includes a stress sensor and a wireless signal transmitter. The stress sensor in the monitoring module is used to collect stress data at the connection points, and the wireless signal transmitter is used to transmit the collected data to an external terminal device.

[0012] The beneficial effects of this utility model are as follows: Through the interlocking slot design, the steel beam can be quickly inserted like a "pin," achieving rapid installation and a highly stable connection, avoiding damage to the galvanized layer caused by traditional welding or bolt connections; the eccentric cam-driven locking slider ensures a firm and stable connection; the integrated monitoring module can sense and transmit stress data at the connection points in real time, enabling online monitoring and early warning of structural health; the flexible anti-slip pad avoids hard metal-to-metal contact, effectively protecting the hot-dip galvanized layer on the steel beam surface; the anti-loosening component effectively prevents the locking mechanism from loosening due to vibration, ensuring safety for long-term use; and it achieves the goals of high connection strength and easy installation.

[0022] Furthermore, in the description of this utility model, unless otherwise stated, "multiple", "multiple groups", and "multiple roots" mean two or more.

[0023] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments;

[0024] like Figure 1 As shown, a quick-locking connector for hot-dip galvanized steel beams includes a locking body 1, a U-shaped insertion groove 11 on the locking body 1, a through hole 111 on the side wall of the insertion groove 11, at least one locking slider 2 that can move radially installed in the through hole 111, an eccentric mechanism 3 installed on the outside of the locking body 1, and a monitoring module 5 integrated on the top of the locking body 1.

[0025] like Figure 2 As shown, the eccentric mechanism 3 includes an eccentric wheel shaft 31 and a cam portion 32. The eccentric wheel shaft 31 is rotatably mounted on the outside of the locking body 1. The cam portion 32 protrudes outward and contacts the outside of the locking slider 2. A flexible anti-slip pad 21 is adhered to the inside of the locking slider 2.

[0026] The flexible anti-slip mat 21 is made of high-polymer elastic material, and the surface of the flexible anti-slip mat 21 is processed with intersecting diamond anti-slip patterns.

[0027] like Figure 3 As shown, the inner wall of the insertion groove 11 of the latch body 1 is provided with a positioning reference surface 112, the outer surface of the latch body 1 is coated with a nano-ceramic coating 12 with a thickness of 0.1mm to 0.2mm, and the latch body 1 is made of high-strength alloy.

[0028] like Figure 2 As shown, an anti-loosening component 4 is installed at the position of the eccentric wheel shaft 31 on the locking body 1. The anti-loosening component 4 includes a stop pin 41 that can be elastically reset, and a slot 321 that matches the stop pin 41 is opened on the side of the cam part 32.

[0029] like Figure 4 As shown, the monitoring module 5 includes a stress sensor 51 and a wireless signal transmitter 52.

[0030] One embodiment of this utility model:

[0031] like Figure 1 and Figure 2 As shown, preparation and insertion: The locking body 1 is pre-fixed to the support structure. The eccentric wheel shaft 31 of the eccentric mechanism 3 is rotated so that the short diameter of the cam portion 32 faces the locking slider 2. At this time, the locking slider 2 is in a retracted state, leaving sufficient space for the insertion of the steel beam. The end of the hot-dip galvanized steel beam is aligned with the insertion slot 11 and inserted until its side is tightly fitted against the positioning reference surface 112.

[0032] Locking and fixing: Rotating the eccentric wheel shaft 31 (e.g., 90° clockwise), the cam portion 32 rotates with the eccentric wheel shaft 31, and its long-diameter portion gradually presses against the outer side of the locking slider 2, pushing the locking slider 2 to move radially inward. The flexible anti-slip pad 21 on the inner side of the locking slider 2 is then pressed against the corresponding surface of the steel beam. Due to the force amplification effect of the cam portion 32, a small rotational torque can be converted into a huge radial clamping force. This clamping force is evenly applied to the surface of the steel beam through the flexible anti-slip pad 21, providing both a huge static friction force to prevent the steel beam from falling out and avoiding scratches on the galvanized layer.

[0033] Anti-loosening locking: When the eccentric wheel shaft 31 rotates to the locked position, the stop pin 41 of the anti-loosening component 4 automatically springs into the slot 321 on the side of the cam part 32 under the action of the spring, making a "click" confirmation sound. At this time, the stop pin 41 restricts the accidental rotation of the cam part 32, realizes mechanical self-locking, and ensures the long-term stability of the connection in a vibration environment.

[0034] Condition Monitoring: After the steel beam is loaded, the load is transmitted to the locking body 1 through the connection points, causing minor deformation of the locking body 1. The stress sensor 51 integrated on the top senses this deformation (strain) in real time and converts it into an electrical signal. After processing, the signal is wirelessly transmitted to a remote monitoring center by the wireless signal transmitter 52. Staff can view the stress data at each connection point in real time, analyze the structural stress state, and promptly issue alarms and take measures to preventative maintenance if any stress anomalies are detected (such as exceeding safety thresholds or sudden changes).

[0035] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications and equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
