[0001] This utility model relates to the field of fall protection devices, and in particular to a fall protection triangular fixing mechanism. Background Technology
[0002] In high-altitude operations, such as the maintenance of power transmission towers, communication towers, and wind power equipment, fall protection systems are crucial. Rail-mounted fall protection systems are widely used due to their high safety, stable operation, and ease of maintenance. Among these systems, the fixing hardware, as a key component of the rail installation, directly affects the system's reliability and applicability.
[0003] Currently, common methods for fixing guide rails include bolt clamping, U-shaped clamps, and welding. However, these methods have certain limitations. Common problems include uneven stress distribution, limited applicability, and inconvenient maintenance. Traditional fixing methods may lead to localized stress concentration under high-intensity wind loads or long-term use, causing bolt loosening or guide rail deformation, thus affecting safety. To address these issues, a new type of fixing hardware is needed to ensure the safety of workers at heights. Utility Model Content

[0005] To achieve the above objectives, this utility model proposes a fall-prevention triangular fixing mechanism, which includes a connecting body. One end of the connecting body is provided with an installation part, and the other end is provided with a connecting part. The connecting part is connected to a fixing structure, and the fixing structure gradually extends away from the installation part.
[0006] The fixing structure includes at least two locking rods, one end of which is connected to the connecting part, and the other end is provided with an adjustable locking structure. The two locking rods are arranged opposite each other, and the included angle between the two locking rods is 90°.
[0007] In one embodiment of this application, the locking rod is provided with a fixing part relative to the connecting part, the fixing part abuts against the connecting part, and the fixing part gradually extends along the direction from the connecting part to the mounting part;
[0008] The included angle between the fixing part and the locking rod is 135°.
[0009] In one embodiment of this application, the two locking rods are disposed opposite to each other on opposite end faces of the connecting portion, the two locking rods are parallel to each other, and enclose a fixed plane;
[0010] The connecting body is perpendicular to the fixed plane.
[0011] In one embodiment of this application, the two locking rods are integrally formed and have a connecting end opposite to the connecting body, and the connecting end is rotatably connected to the connecting part;
[0012] The end of the connecting body away from the mounting part is provided with a limiting part opposite to the connecting part, and the locking rod is connected to the limiting part.
[0013] In one embodiment of this application, the adjustable locking structure includes a locking plate and a limiting structure. The locking rod is provided with an external thread relative to the limiting structure. The limiting structure is screwed onto the external thread and abuts against the locking plate.
[0014] The locking plate is slidably connected to the locking rod, and one end of the locking rod is provided with a snap-fit part facing the connection part.
[0015] In one embodiment of this application, the limiting structure includes a washer, a first locking nut, and a second locking nut. The washer abuts against the end of the locking nut that is away from the connecting body, the first locking nut abuts against the washer, and the second locking nut abuts against the first locking nut.

[0017] By adopting the above technical solution, this utility model has the following advantages:
[0018] 1. One end of the connecting body is equipped with a mounting part, which is a mounting hole structure. The connecting body can be quickly and stably fixed to equipment such as power transmission towers, communication towers, and construction sites using the mounting hole. The connecting part is located at the end of the connecting body away from the mounting part. The connecting part can be a connecting hole structure that allows the fixing structure to pass through the connecting hole to achieve the effect of quickly fixing and restricting the fixing structure. It can also be a connecting structure that facilitates the installation and clamping of the fixing structure.

[0027] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0028] Reference Figures 1 to 2 To achieve the above objectives, this utility model proposes a fall-prevention triangular fixing mechanism, which includes a connecting body 1. One end of the connecting body 1 is provided with an installation part 11, and the other end is provided with a connecting part 12. The connecting part 12 is connected to a fixing structure 2, and the fixing structure 2 gradually extends in a direction away from the installation part 11.
[0029] The fixing structure 2 includes at least two locking rods 3. One end of the locking rod 3 is connected to the connecting part 12, and the other end is provided with an adjustable locking structure 4. The two locking rods 3 are arranged opposite each other, and the included angle between the two locking rods 3 is 90°.
[0030] One end of the connecting body 1 is provided with a mounting part 11, which is a mounting hole structure. The mounting hole allows the connecting body 1 to be quickly and stably fixed to equipment such as power transmission towers, communication towers, and building construction. The connecting part 12 is located at the end of the connecting body 1 away from the mounting part 11. The connecting part 12 can be a connecting hole structure that allows the fixing structure 2 to pass through the connecting hole to achieve the effect of quickly fixing and restricting the fixing structure 2. It can also be a connecting structure that facilitates the installation and locking of the fixing structure 2. Alternatively, the connecting part 12 can facilitate the welding of the fixing structure 2 to it. The main purpose of the connecting body 1 is to facilitate the installation of the fixing structure 2 and to use the mounting part 11 to install the fixing structure 2 in a designated position, which can effectively reduce maintenance costs.
[0031] The fixed structure 2 includes at least two locking rods 3, with an included angle of 90° between the two locking rods 3. The main function of the fall-prevention triangular fixing mechanism of this application is to lock the "I" or "H" steel through the fixed structure 2. The corner of the steel is 90°. By designing the clamp between the two locking rods 3 to be 90°, the steel can be directly inserted into the fixed structure 2, and the corner of the steel is connected to the connecting part 12. Under this structure, the two locking rods 3 can be as close as possible to the two sides of the steel, making the distance between the adjustable locking structure 4 and the steel closer, effectively improving the locking strength of the adjustable locking structure 4, so that the fall-prevention triangular fixing mechanism can achieve high overall structural strength, high connection strength, and strong fall-prevention performance.
[0032] A locking rod 3 is provided with at least one set of adjustable locking structures 4. Different adjustable locking structures 4 can be adjusted independently. A locking rod 3 is connected to one side of the steel. The adjustable locking structure 4 can be a mounting tooth structure provided on the locking rod 3. Different teeth are different stops to correspond to different specifications of steel. The snap-fit structure snaps into different teeth, which can effectively lock steel of different specifications. By adjusting one set of adjustable locking structures 4, one side of the steel can be quickly locked. The two locking rods 3 and the adjustable locking structures 4 work together to achieve efficient and stable locking of the steel, which can effectively prevent the steel from falling due to unstable installation.
[0033] See also Figures 1 to 2 In one embodiment of this application, the locking rod 3 is provided with a fixing part 31 relative to the connecting part 12. The fixing part 31 abuts against the connecting part 12 and the fixing part 31 gradually extends along the direction from the connecting part 12 to the mounting part 11.
[0034] The included angle between the fixing part 31 and the locking rod 3 is 135°.
[0035] In one embodiment of this application, the two locking rods 3 are independent rod structures. Each locking rod 3 needs to be independently installed on the connecting body 1. One end of the locking rod 3 is provided with a fixing part 31 opposite to the connecting part 12. The included angle between the fixing part 31 and the locking rod 3 is 135°. Under this structure, after the two locking rods 3 are fixed, the included angle between the two locking rods 3 is 90°, which can effectively make the locking rod 3 close to the steel and improve the stability of locking.
[0036] The fixing part 31 and the locking rod 3 can be integrally molded to ensure structural strength, or the locking rod 3 can be cast as a single piece and bent to form the fixing part 31. This structure can effectively improve production efficiency and ensure product quality.
[0037] See also Figure 2 In one embodiment of this application, two locking rods 3 are disposed opposite to each other on opposite end faces of the connecting part 12, the two locking rods 3 are parallel to each other, and enclose a fixed plane.
[0038] The connecting body 1 is perpendicular to the fixed plane.
[0039] Two locking rods 3 are positioned opposite each other on the left and right end faces of the connecting body 1. The projection of the locking rods 3 onto the connecting body 1 forms projection rods. The projection rods are connected to the fixing parts 31 and are located within the extension line of the fixing parts 31. Furthermore, the projections of the two fixing parts 31 of the two locking rods 3 onto the connecting body 1 coincide with each other. Through this structure, when the fixing structure 2 is installed and subjected to force, the fixing structure 2 can evenly transmit the force to the connecting body 1. This structure can effectively improve the strength of the entire structure and effectively prevent the steel from falling.
[0040] See also Figure 1 In one embodiment of this application, two locking rods 3 are integrally formed and have a connecting end relative to the connecting body 1, and the connecting end is rotatably connected to the connecting part 12;
[0041] The end of the connecting body 1 away from the mounting part 11 is provided with a limiting part opposite to the connecting part 12, and the locking rod 3 is connected to the limiting part.
[0042] In another feasible embodiment of this application, the two locking rods 3 are integrally formed, which can ensure the strength of the fixing structure 2 itself. The intersection of the two rods is provided with a connecting end. Using the connecting end, the position of the fixing structure 2 can be adjusted, which can better adapt to and adjust the fixing steel. The limiting part is generally a supporting structure facing the fixing structure 2. The supporting structure is 90°. The supporting structure can hold back one corner of the steel, and then the fixing structure 2, which is easy to adjust, is used for locking. This structure can effectively improve the strength of the entire structure and ensure the user's experience.
[0043] See also Figure 1 In one embodiment of this application, the adjustable locking structure 4 includes a locking plate 41 and a limiting structure 5. The locking rod 3 is provided with an external thread relative to the limiting structure 5. The limiting structure 5 is screwed to the external thread and abuts against the locking plate 41.
[0044] The locking plate 41 is slidably connected to the locking rod 3, and one end of the locking rod 3 is provided with a snap-fit part 42 facing the connecting part 12.
[0045] In order for the adjustable locking structure 4 to lock the steel flexibly and firmly, the adjustable locking structure 4 generally includes a locking plate 41 and a limiting structure 5. The limiting structure 5 is adjusted in position by the external thread on the surface of the locking rod 3. The locking plate 41 can abut against the corner of the steel through the limiting structure 5. The snap-fit part 42 can further restrict the steel and effectively ensure the stability of the connection.
[0046] See also Figures 1 to 2 In one embodiment of this application, the limiting structure 5 includes a washer, a first locking nut, and a second locking nut. The washer abuts against the end of the locking piece 41 that is away from the connecting body 1, the first locking nut abuts against the washer, and the second locking nut abuts against the first locking nut.
[0047] The first locking nut locks the locking plate 41 by pressing the washer. The second locking nut is used to lock the first locking nut, which can ensure that the first nut will not loosen. Based on this, the first locking nut is generally used to bear the entire locking force. The thickness of the first locking nut is generally greater than that of the second locking nut to ensure the stability of the locking of the restriction structure 5.
[0048] See also Figure 1 In one embodiment of this application, the locking piece 41 has an abutment portion at one end away from the latching portion 42. The abutment portion and the latching portion 42 are located on the same end face of the locking piece 41, and the abutment portion abuts against the locking rod 3.
[0049] The locking piece 41 is also provided with an abutment portion. When the locking portion 42 is subjected to force, the other end of the locking piece 41 will rotate slightly toward the locking piece 41, which may easily lead to unstable locking. The abutment portion is close to the connection between the locking piece 41 and the locking rod 3. After the locking portion 42 is subjected to force, it can increase the contact area between the locking piece 41 and the locking rod 3, reduce the stress on the locking piece 41, and effectively protect the structure of the locking piece 41 itself.
