DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0025] Please refer toFigures 1-6 This utility model provides a technical solution: a self-locking safety belt buckle for building construction, including a buckle mechanism 1. The main body of the buckle mechanism 1 is a frame structure. A through hole is opened inside the buckle mechanism 1, and a guide rod mechanism 3 is inserted into the through hole. The main body of the guide rod mechanism 3 is a cylindrical structure.

[0026] A limiting plate 301 is fixedly connected to the top surface of the guide rod mechanism 3. The limiting plate 301 is a rectangular plate structure. A limiting plate 3011 is fixedly connected to the outer side of the guide rod mechanism 3. The main body of the limiting plate 3011 is a disc-shaped structure. There are two limiting plates 3011. The two limiting plates 3011 are fixedly connected in a straight array on the upper and lower sides of the outer periphery of the guide rod mechanism 3. A reset component 3012 is fixedly connected to the top surface of the lower limiting plate 3011. The top of the reset component 3012 is fixedly connected to the bottom surface of the locking mechanism 1. A connector 3013 is fixedly connected to the bottom end of the lower limiting plate 3011. An external thread is opened on the outer periphery of the connector 3013. A sleeve assembly 3014 is screwed onto the outer side of the connector 3013. A connecting plate 3015 is fixedly connected to the bottom end of the sleeve assembly 3014. A connecting hole 3016 for passing a rope is opened inside the connecting plate 3015.

[0027] By inserting a guide rod mechanism 3 into the locking mechanism 1, and setting a limiting plate 301, a limiting plate 3011, a reset component 3012, a connector 3013, a sleeve assembly 3014, a connecting plate 3015, and a connecting hole 3016, the connection function between the safety belt and the external rope is realized. At the same time, the reset component 3012 provides a certain buffering and reset function, which facilitates the use and adjustment of the safety belt.

[0028] See Figure 1 , Figure 4 A side plate assembly 101 is fixedly connected to the inner side of the left opening of the locking mechanism 1. There are two side plate assemblies 101, which are fixedly connected in a straight line array to the front and rear sides of the bottom surface of the locking mechanism 1.

[0029] By setting two side plate assemblies 101 inside the left opening of the locking mechanism 1, an installation base is provided for the subsequent installation of the pivot assembly 1011 and the lever assembly 1012, thereby enhancing the structural integrity and functionality of the locking mechanism 1.

[0030] See Figure 2 , Figure 3 The side plate assembly 101 is rotatably connected to the inside of the rotating shaft assembly 1011, and the rotating shaft assembly 1011 is fixedly connected to the outside of the rotating shaft assembly 1012.

[0031] By rotating the connecting shaft assembly 1011 inside the side plate assembly 101, and fixing the dial plate assembly 1012 outside the connecting shaft assembly 1011, the dial plate assembly 1012 can rotate around the connecting shaft assembly 1011, realizing the activity function of the dial plate assembly 1012, and providing the possibility for locking and unlocking operation.

[0032] Referring to Figure 5 , Figure 6 , the bottom end surface of the dial plate assembly 1012 is fixedly connected with a locking plate 1013, and the locking plate 1013 and the dial plate assembly 1012 together constitute a limiting structure, and the inside of the locking buckle mechanism 1 is fixedly connected with a connecting mechanism 2;

[0033] By fixing the locking plate 1013 at the bottom end of the dial plate assembly 1012 to form a limiting structure with the dial plate assembly 1012, and cooperating with the connecting mechanism 2 inside the locking buckle mechanism 1, the connection state of the safety belt can be limited and locked to prevent accidental unlocking and ensure the safety of construction personnel.

[0034] Referring to Figure 1 , Figure 2 , the right end surface of the dial plate assembly 1012 is fixedly connected with a hanging ring assembly 2012, and the inside of the hanging ring assembly 2012 and the connecting mechanism 2 is installed with a connecting ring 201;

[0035] By fixing the hanging ring assembly 2012 at the right end of the dial plate assembly 1012, and installing the connecting ring 201 inside the hanging ring assembly 2012 and the connecting mechanism 2, a connecting point is provided for the connection of the safety belt with external objects, which facilitates the connection of the safety belt buckle with fixed objects such as building structures.

[0036] Referring to Figure 3 , Figure 5 , the connecting ring 201 is provided with two places, and the inside of the two connecting rings 201 is fixedly connected with a spring rod 2011;

[0037] By setting two connecting rings 201 and fixing spring rods 2011 inside them, the elasticity of the spring rods 2011 is used to provide the power for resetting the dial plate assembly 1012 and the locking plate 1013, ensuring the stability and reliability of the safety belt buckle during use.

[0038] Referring to Figure 1 , Figure 2 , the spring rod 2011 is a telescopic rod structure with a spring, and the spring rod 2011 and the connecting ring 201 together constitute a resetting structure for the dial plate assembly 1012 and the locking plate 1013;

[0039] The spring rod 2011 is designed as a telescopic rod structure with a spring, and together with the connecting ring 201 forms a reset structure, so that the push plate assembly 1012 and the locking plate 1013 can quickly reset after being subjected to external force, ensuring the normal use and safety of the safety belt buckle.

[0040] In use, when the safety belt buckle is used, the rope is first threaded through the connecting hole 3016 of the connecting plate 3015, and the sleeve assembly 3014 is adjusted to adjust the position of the connecting head 3013, thereby adjusting the fixed length of the rope to meet the needs of different construction scenes. At this time, the guide rod mechanism 3 is in the initial position under the action of the reset assembly 3012, and the limiting support plate 301 and the upper and lower limiting plates 3011 limit the guide rod mechanism 3, ensuring its stability.

[0041] The locking buckle mechanism 1 body is connected with external building structures and the like, and when the construction personnel fasten the safety belt, the body generates gravity or is subjected to external force, the guide rod mechanism 3 will be subjected to downward force, and due to the blocking of the limiting plate 3011, the guide rod mechanism 3 will not be separated from the locking buckle mechanism 1. At the same time, the side plate assembly 101 on the inner side of the left opening of the locking buckle mechanism 1 rotates the shaft assembly 1011 connected thereto, which drives the push plate assembly 1012 to rotate, and the locking plate 1013 at the bottom end of the push plate assembly 1012 rotates and cooperates with the connecting mechanism 2 to lock the safety belt buckle, preventing accidental opening.

[0042] As the pulling force on the construction personnel increases, the downward force on the guide rod mechanism 3 also increases, further compressing the reset assembly 3012, and at the same time, the range of movement of the push plate assembly 1012 and the locking plate 1013 is also limited, making the locking between the locking plate 1013 and the connecting mechanism 2 more complete, realizing the self-locking function of the safety belt buckle being tighter under greater force, effectively protecting the safety of the construction personnel. In this process, the spring rod 2011 inside the connecting ring 201 will extend or contract according to the force, providing a stable reset force for the push plate assembly 1012 and the locking plate 1013, ensuring that the locking structure always remains tight.

[0043] When the construction personnel need to unfasten the safety belt after completing the work, the push plate assembly 1012 is manually operated to overcome the elastic force of the spring rod 2011, so that the locking plate 1013 is separated from the connecting mechanism 2, and the locking of the safety belt is released. Then, the guide rod mechanism 3 is reset upward under the elastic force of the reset assembly 3012, returning to the initial position for next use.

[0044] As described above, the device can limit the movement range of the guide rod mechanism 3 by providing the limiting plate 3011.

[0045] Meanwhile, the contents not described in detail in the specification are all prior art known to those skilled in the art.
