Description

Technical Field

[0001] This utility model relates to the technical field of locking devices, specifically a locking hook for steel pipes on construction sites. Background Technology

[0002] Currently, steel pipes have many uses in the construction industry, with scaffolding being the most common application. After scaffolding is erected, it generally needs to be fastened to the hanging rings on the front of the building to ensure stability. This requires the use of locking hooks. However, current locking hooks generally require a chain to work together. One end of the chain is looped onto the steel pipe, and the locking hook connects to the corresponding hanging ring. However, considering that the figure-eight chain connection is used, there is a movable connection between the figure-eight chain and the locking hook, which results in poor stability of the scaffolding. At the same time, current locking hooks generally use spring locks. When the locking hook is exposed to the outside for a long time, the spring elasticity is prone to deterioration, eventually leading to unstable locking of the locking hook. Therefore, improvements are needed. Utility Model Content

[0003] The purpose of this utility model is to provide a locking hook for steel pipes on construction sites to solve the problems mentioned in the background art, such as poor stability after the existing locking hooks are connected to the steel pipes, and the fact that the locking hooks generally use spring locks, which are exposed to the outside for a long time, making the spring elasticity deteriorate and ultimately leading to unstable locking of the locking hooks.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a locking hook for steel pipes on construction sites, comprising a locking hook housing and a locking hook portion. One side of the locking hook housing is provided with a steel pipe mounting hole for connecting to a steel pipe. The locking hook portion is located at the other end of the locking hook housing. One end of the locking hook portion is provided with a rotating support that rotates around the center of the locking hook housing as a hinge point. The rotating support allows the locking hook portion to rotate between a first position and a second position. The locking hook housing is provided with a locking mechanism that can lock the locking hook portion when it is rotated to the first or second position.

[0005] Preferably, the locking hook housing includes an upper housing and a lower housing that cooperate with each other. The upper housing is provided with one or more locking screws, and the lower housing is provided with threaded holes that are threadedly connected to the locking screws. The locking screws are located on both sides of the steel pipe mounting hole.

[0006] Preferably, for ease of rotation, the lower housing is provided with a rotating groove, a rotating rod is provided at the center of the rotating groove, the rotating support is rotatably connected to the outside of the rotating rod, and a rotating bearing is provided between the rotating rod and the rotating support.

[0007] Preferably, for ease of operation, the locking mechanism includes a locking positioning pin, and the rotating support is provided with an arc-shaped through hole. The locking positioning pin is movably inserted into the arc-shaped through hole, and the rotating groove is also provided with locking grooves located directly below both ends of the arc-shaped through hole. When the locking positioning pin is pressed down, it can pass through the corresponding through hole of the arc-shaped through hole and be inserted into the corresponding locking groove.

[0008] As a preferred embodiment, to achieve the rotational guiding function, the rotating support is further provided with an arc-shaped waist groove through hole II, and the rotating groove is further provided with a positioning guide rod that is movably inserted into the arc-shaped waist groove through hole II.

[0009] Preferably, for ease of disassembly, the positioning guide rod is a screw, and the rotating groove is provided with an internal thread that engages with the positioning guide rod.

[0010] Preferably, for ease of later disassembly, the rotating rod is an internal hex screw.

[0011] Preferably, for ease of positioning, a limiting nut is provided outside the locking and positioning pin. After the locking and positioning pin is pressed down, the lower end face of the limiting nut abuts against the upper surface of the upper housing to achieve positioning.

[0012] Compared with the prior art, the beneficial effects of this utility model are: through the above-mentioned structural design, the steel pipe can be directly and tightly connected to the hanging ring without the need for a figure-eight chain, which further improves the stability of the installation (since the steel pipe and the hanging ring are directly connected by this locking hook), and the subsequent disassembly and installation are also relatively convenient.

[0022] Example 1

[0023] Please see Figures 1-6 As shown in the figure, this embodiment discloses a steel pipe locking hook for construction sites, including a locking hook housing 1 and a locking hook part 2. One side of the locking hook housing 1 is provided with a steel pipe mounting hole 3 for connecting with a steel pipe. The locking hook part 2 is located at the other end of the locking hook housing 1. One end of the locking hook part 2 is provided with a rotating support 4 that rotates around the center of the locking hook housing 1 as a hinge point. The rotating support 4 allows the locking hook part 2 to rotate between a first position and a second position. The locking hook housing 1 is provided with a locking mechanism 5 that can lock the locking hook part 2 when it is rotated to the first position or the second position. In this structure, the locking hook housing 1 includes an upper housing 101 and a lower housing 102 that cooperate with each other. The upper housing 101 is provided with one or more locking screws 103. The lower housing 102 is provided with a threaded hole 104 that is threadedly connected to the locking screw 103, and the locking screw 103 is located on both sides of the steel pipe mounting hole 3.

[0024] Preferably, for ease of rotation, the lower housing 102 is provided with a rotating groove 7, and a rotating rod 8 is provided at the center of the rotating groove 7 for easy disassembly. The rotating rod 8 is an internal hexagon screw. The rotating support 4 is rotatably connected to the outside of the rotating rod 8, and a rotating bearing 9 is provided between the rotating rod 8 and the rotating support 4. In this structure, the addition of a rotating bearing 9 between the rotating rod 8 and the rotating support 4 enables flexible rotation.

[0025] Preferably, for ease of operation, the locking mechanism 5 includes a locking positioning pin 501. The rotating support 4 is provided with an arc-shaped through hole 401. The locking positioning pin 501 is movably inserted into the arc-shaped through hole 401. The rotating groove 7 is also provided with locking grooves 701 located directly below both ends of the arc-shaped through hole 401. When the locking positioning pin 501 is pressed down, it can pass through the corresponding through hole of the arc-shaped through hole 401 and be inserted into the corresponding locking groove 701. For easy positioning, a limiting nut 6 is provided outside the locking positioning pin 501. After the locking positioning pin 501 is pressed down, the lower end face of the limiting nut 6 abuts against the upper surface of the upper housing 101 to achieve positioning. Through the above structural configuration, the locking hook 2 can be quickly rotated to the first and second positions.

[0026] Preferably, to achieve the rotational guiding function, the rotating support 4 is also provided with an arc-shaped waist groove through hole 402, and the rotating groove 7 is also provided with a positioning guide rod 10 that is movably inserted into the arc-shaped waist groove through hole 402 for easy disassembly later.

[0027] During installation, the steel pipe can be directly inserted into the steel pipe mounting hole 3 and locked using the locking screws 103 on both sides. To ensure a secure locking effect, a silicone sleeve can be placed inside the steel pipe mounting hole 3 to further clamp the steel pipe. Then, by first pulling the locking mechanism 5, the lower part of the locking mechanism 5 separates from the locking groove 701. At this point, the rotating support 4 can rotate around the rotating rod 8. Figure 1 The state rotates to Figure 3 In this state, the locking hook 2 will pass through the hanging ring in front of the building and connect with the hanging ring. Through the above structural setting, the steel pipe can be directly and tightly connected to the hanging ring without the need to use a figure-eight chain, which further improves the stability of the installation (because the steel pipe and the hanging ring are directly connected by this locking hook). In addition, the disassembly and installation are also relatively convenient in the later stage.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
