[0021] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0022] Reference Figures 1-3 This utility model provides an embodiment of a limiting protection structure for the opening and closing angle of a pipe clamp, comprising an upper clamp body 5 and a limiting rod 6. A lower clamp body 11 is provided on the lower side of the upper clamp body 5. A connecting plate 2 7 is fixedly connected to the right side of both the lower clamp body 11 and the upper clamp body 5. A connecting rod 1 4 is provided on the left side of the front of the upper clamp body 5. A connecting rod 2 12 is provided on the right side of the front of the lower clamp body 11. A limiting rope 16 is fixedly connected to the side wall between the connecting rod 1 4 and the connecting rod 2 12. A connecting plate 3 14 is fixedly connected to the left side of the lower clamp body 11. A limiting post 2 18 is fixedly connected to the upper side of the connecting plate 3 14. A connecting plate 1 1 is fixedly connected to the left side of the upper clamp body 5. A circular hole 19 is provided on the lower side of the connecting plate 1 1. The limiting post 2 18 and the circular hole 19 are interference-fitted. The outer wall of the limiting rod 6 passes through the two connecting plates 2 7.
[0023] In this embodiment, Figure 1 The device is oriented in all directions: front, back, left, and right. When using the device, hold the lower clamp 11 with one hand and move the upper clamp 5 upward with the other hand, so that the two connecting plates 7 are respectively located at the two ends of the limiting rod 6. Open the upper clamp 5 to the upper right angle until the upper connecting plate 7 and the limiting rod 6 interfere. At the same time, the limiting rope 16 between the connecting rod 4 and the connecting rod 12 is in a straight state, thus limiting the opening angle of the device. The pipe to be fastened is placed between the upper clamp 5 and the lower clamp 11 through the space opened on the upper left side, and the upper clamp 5 and the lower clamp 11 are closed. Through the interference fit of the limiting post 18 and the round hole 19, the upper clamp 5 and the lower clamp 11 have a certain resistance when they are closed, thus solving the problem of excessive opening and closing of the pipe clamp.
[0024] Reference Figure 2 The limiting rod 6 includes a limiting head 9, which has two limiting heads. A limiting post 8 is fixedly connected between the side walls of the two limiting heads 9. The outer wall of the limiting post 8 passes through two connecting plates 7, and there is a certain gap between the outer wall of the limiting post 8 and the connecting plate 7.
[0025] Specifically, the gap between the outer wall of the limiting post 8 and the connecting plate 7 allows the connecting plate 7 to form a certain angle with the limiting post 8 on the plane, ensuring that when the upper clamp 5 and the lower clamp 11 are opened, the distance between the right ends of the connecting plate 1 and the connecting plate 3 14 is greater than the diameter of the pipe to be fastened, thereby enabling the insertion of the pipe to be fastened while restricting the opening and closing of the device.
[0026] Reference Figure 2 The outer wall of connecting rod 14 passes through the front and rear sides of the upper clamp 5, and the outer wall of connecting rod 212 passes through the front and rear sides of the lower clamp 11. There are two limiting ropes 16, and the two ends of one of the limiting ropes 16 are fixedly connected to the side wall between the rear end of connecting rod 14 and the rear end of connecting rod 212, respectively.
[0027] Specifically, the limiting rope 16 is a high-strength steel wire rope, which is existing technology. When the upper clamp 5 and the lower clamp 11 are opened, the limiting rope 16 connects the upper clamp 5 and the lower clamp 11 and pulls on the upper clamp 5. When the force of opening the device can deform the connecting plate 7, the limiting rope 16 forms a secondary opening angle limit on the device, further strengthening the limiting protection function of the device.
[0028] Reference Figures 1-3 Both connecting plate 1 and connecting plate 2 are equipped with fastening bolts 2 inside. The outer wall of the fastening bolt 2 on the right passes through the two connecting plates 2 7, and the outer wall of the fastening bolt 2 on the left passes through connecting plate 1 and connecting plate 3 14. The lower end of the fastening bolt 2 is threaded with an anti-loosening nut 10. The outer wall of the fastening bolt 2 is equipped with a washer 3. The two washers 3 are respectively set on the upper side of connecting plate 1 and connecting plate 2 7. The upper clamp 5 and the lower clamp 11 are equipped with buffer pads 13 on opposite sides. The upper side of connecting plate 3 14 is fixedly connected with an observation column 17. A through hole 15 is opened on connecting plate 1. The observation column 17 and the through hole 15 are slidably connected. The height of the observation column 17 is the same as the thickness of connecting plate 1.
[0029] Specifically, when the pipe to be tightened is placed into the device, the position of the pipe is adjusted so that the buffer pad 13 wraps around the outer wall of the pipe. The right-side fastening bolt 2 is passed through the right-side washer 3 and connecting plate 7, and screwed into the right-side anti-loosening nut 10 to complete the tightening of the right side of the upper clamp 5 and the lower clamp 11. Similarly, the left side of the upper clamp 5 and the lower clamp 11 is tightened by the left-side fastening bolt 2, washer 3 and anti-loosening nut 10. The interference fit between the limiting post 18 and the round hole 19 provides some resistance when the left-side fastening bolt 2 and the left-side anti-loosening nut 10 are threaded. When the observation post 17 and the upper surface of the connecting plate 1 are flush through the through hole 15, the left side of the device is tightened, thus solving the problem of excessive opening and closing of the pipe clamp.
[0030] Working principle: When using this device, hold the lower clamp 11 with one hand and move the upper clamp 5 upwards with the other hand, so that the two connecting plates 7 contact one side of the two limiting heads 9 respectively. Open the upper clamp 5 to the upper right until the outer wall of the upper connecting plate 7 and the limiting post 8 contacts each other, while keeping the limiting rope 16 between the connecting rod 4 and the connecting rod 12 taut, thus limiting the opening angle of the device. Insert the pipe to be tightened through the opening on the upper left side between the upper clamp 5 and the lower clamp 11, and close the upper clamp 5 and the lower clamp 11 so that the buffer pad 13 wraps around the pipe. Tighten the right side... The fastening bolt 2 passes through the right-side washer 3 and connecting plate 7, and is screwed into the right-side anti-loosening nut 10, thus completing the fastening of the right side of the upper clamp 5 and the lower clamp 11. Similarly, the left side of the upper clamp 5 and the lower clamp 11 is fastened by the fastening bolt 2, washer 3 and anti-loosening nut 10. Through the interference fit of the limiting post 18 and the round hole 19, the left-side fastening bolt 2 and the left-side anti-loosening nut 10 have a certain resistance when threaded. When the observation post 17 and the upper surface of the connecting plate 1 are flush when observed or touched through the through hole 15, the left side of the device is fastened, thus solving the problem of excessive opening and closing of the pipe clamp.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
