Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Please see Figure 1-5This utility model provides a technical solution for a segmented water-stop bolt, including an inner rod 1 and two outer rods 2. The inner rod 1 and the outer rods 2 are the two main components of the segmented water-stop bolt. The two ends of the inner rod 1 are respectively threaded with outer rods 2 through tapered sleeves 3. The tapered sleeves 3 are the intermediate medium connecting the outer rods 2 and the inner rod 1, and the connection is made by threads. A mountain-shaped clamp 10 is sleeved on the outer wall of the outer rod 2. The mountain-shaped clamp 10 is used to limit the scaffolding pipes used in construction. A folding assembly 5 is provided between the mountain-shaped clamp 10 and the outer rod 2. The folding assembly 5 dynamically connects the mountain-shaped clamp 10 and the outer rod 2. The folding assembly 5 includes a first connecting plate 52 and a second connecting plate 54 that are movably connected to each other. The first connecting plate 52 and the second connecting plate 54 are structures that connect the mountain-shaped clamp 10 and the outer rod 2. The first connecting plate 52 and the second connecting plate 54 are movably connected to the outer rod 2 and the mountain-shaped clamp 10, respectively. A control component 7 is installed at the connection between the first connecting plate 52 and the second connecting plate 54. The control component 7 is used to control the folding state of the first connecting plate 52 and the second connecting plate 54. The control component 7 includes a pusher 71 and a second insert rod 72. The pusher 71 in the control component 7 pushes the first connecting plate 52 and the second connecting plate 54 into a straight state. After the first connecting plate 52 and the second connecting plate 54 are pushed into a straight state, the mountain-shaped clamp 10 is pushed to slide on the outer wall of the outer rod 2. After the mountain-shaped clamp 10 is pushed, it fixes the pipe on the building template. The second insert rod 72 is inserted into the interior of the outer rod 2, and the second insert rod 72 has a locking interface 73. The outer rod 2 is provided with a locking component 8. The locking component 8 includes a locking bend rod 86. The locking bend rod 86 locks the locking interface 73 to lock the straight state of the first connecting plate 52 and the second connecting plate 54, thereby locking the fixing of the pipe body by the mountain-shaped clamp 10.

[0025] Under the action of the first connecting plate 52 and the second connecting plate 54, the mountain-shaped clamp 10 is pushed, and then the locking lever 86 is inserted into the locking interface 73 to fix the second insert 72, and also to fix the push frame 71. This makes the mountain-shaped clamp 10 lock the tube body after being pushed. When disassembly is required, the locking lever 86 is disengaged from the locking interface 73, and the fixing of the second insert 72 stops. The mountain-shaped clamp 10 is no longer locked. Based on the above description, the mountain-shaped clamp can quickly install and disassemble the tube body.

[0026] like Figure 1 and Figure 2As shown, during use, the mountain-shaped clamp 10 can move on the outer wall of the outer rod 2. After moving, the mountain-shaped clamp 10 clamps and fixes the tube of the building template. The push frame 71 in the push control component 7 pushes the connection between the first connecting plate 52 and the second connecting plate 54. After the first connecting plate 52 and the second connecting plate 54 are pushed into a straight state, the second connecting plate 54 pushes the mountain-shaped clamp 10 to move. The clamp of the mountain-shaped clamp 10 is tightened. After the second insertion rod 72 descends with the push frame 71, the snap-fit ​​lever 86 in the locking component 8 snaps into the inside of the snap-fit ​​interface 73, locking and limiting the second insertion rod 72 and the push frame 71, fixing the straight state of the first connecting plate 52 and the second connecting plate 54, and also fixing the clamp of the mountain-shaped clamp 10 on the tube. When it is necessary to disassemble the mountain-shaped clamp 10, the snap-fit ​​lever 86 can be disengaged from the inside of the snap-fit ​​interface 73 to release the fixing state of the mountain-shaped clamp 10 on the tube, and then the mountain-shaped clamp 10 can be disassembled.

[0027] Combination Figure 2 In the current state, the folding assembly 5 includes a first support plate 51 and a second support plate 53. The first support plate 51 and the second support plate 53 are structures in which the first connecting plate 52 and the second connecting plate 54 are connected to the outer rod 2 and the mountain-shaped clamp 10. The first support plate 51 and the second support plate 53 are respectively installed on the outer rod 2 and the mountain-shaped clamp 10. The first connecting plate 52 and the second connecting plate 54 are respectively movably installed on the first support plate 51 and the second connecting plate 53. The first connecting plate 52 and the second connecting plate 54 are movably connected by the movable connecting assembly 9.

[0028] During the folding motion, the first connecting plate 52 and the second connecting plate 54 rotate on the first support plate 51 and the second support plate 53. The connection method is shaft connection. After the folding assembly 5 rotates, it can drive the mountain-shaped clamp 10 to move and clamp and fix the tube.

[0029] Combination Figure 2 and Figure 3 It can be seen that the movable connecting assembly 9 includes a connecting cylinder 91 and a connecting plate 93. The connecting cylinder 91 is installed on the first connecting plate 52, and the connecting plate 93 is installed on the second connecting plate 54. A rotating rod 92 is installed on the connecting plate 93. The connecting plate 93 is used to support the rotating rod 92. The rotating rod 92 is inserted into the inside of the connecting cylinder 91, thereby achieving the feature of rotation. The push frame 71 is installed on the outer wall of the connecting cylinder 91.

[0030] like Figure 3 As shown, after the rotating rod 92 is inserted into the interior of the connecting cylinder 91, the first connecting plate 52 and the second connecting plate 54 are connected. The rotating rod 92 rotates inside the connecting cylinder 91. When the pusher 71 pushes the connecting cylinder 91, the movement of the connection point of the first connecting plate 52 and the second connecting plate 54 can be controlled so that the movable connecting assembly 9 rotates.

[0031] Combination Figure 2 , Figure 3 , Figure 4 and Figure 5 The position of each structure of the control component 7 can be understood. The control component 7 includes a push frame 71. Both ends of the push frame 71 are connected to the outer wall of the connecting cylinder 91. A second insert rod 72 is installed at the bottom of the middle part of the push frame 71. The second insert rod 72 moves in and out of the outer rod 2 with the push frame 71. The second insert rod 72 is inserted into the interior of the outer rod 2, and a locking interface 73 is opened at the end inserted into the interior of the outer rod 2. After the locking interface 73 is fixed, the second insert rod 72 and the push frame 71 are fixed.

[0032] In use, after the pusher frame 71 is pressed down, both ends of the pusher frame 71 push the connecting cylinder 91 down to push the first connecting plate 52 and the second connecting plate 54 to move. Specifically, this is achieved by... Figure 3 This allows the second insert rod 72 to be inserted into the interior of the outer rod 2, as shown in the reference. Figure 5 Then, the connecting rod 86 is inserted into the card interface 73 to fix the second insert rod 72 and the push frame 71.

[0033] like Figure 4 As shown, in order to fix the first connecting plate 52 and the second connecting plate 54 in a flat state, and also to fix the tube body clamped by the mountain-shaped clamp 10, a locking assembly 8 is used. The locking assembly 8 includes a through cylinder 82, on which a control rod 81 is mounted. The control rod 81 can extend and retract inside the through cylinder 82. The through cylinder 82 is installed on the end face of the outer rod 2. The control rod 81 is inserted into the inside of the through cylinder 82. A compression spring 84 is sleeved on the outer wall of the control rod 81. The control rod 81 is a fixed operating structure, mainly used to drive the movement of the locking crank 86. The two ends of the compression spring 84 are respectively provided with a baffle 83 and a retaining ring 85. The baffle 83 and the retaining ring 85 are used to limit the compression spring 84, so that it generates elasticity to push the control rod 81. There are two baffles 83, and The outer rod 2 is fixedly attached to the outer wall of the control rod 81 in an upper and lower distribution. The retaining ring 85 is sleeved on the outer wall of the control rod 81. Both ends of the retaining ring 85 are connected to the inner wall of the outer rod 2. The retaining ring 85 blocks one end of the compression spring 84, and the force that restricts this end is provided by the outer rod 2. The other end of the compression spring 84 pushes the baffle 83 and the control rod 81 to move. The baffle 83 and the retaining ring 85 are respectively in contact with the two ends of the compression spring 84. One end of the control rod 81 is equipped with one end of the locking crank 86. The other end of the crank 86 is locked with the locking interface 73. The locking crank 86 is locked into the interior of the locking interface 73 to fix the insert rod 72. The end of the locking crank 86 is provided with a dynamic support component 4. The support component 4 supports the other end of the locking crank 86 in a movable state to make its movement stable.

[0034] refer to Figure 4The elasticity of the compression spring 84 pushes the baffle 83 to move the control rod 81. The control rod 81 drives the snap-fit ​​lever 86 to snap into the inside of the snap-fit ​​interface 73, fixing the insert rod 72 and the push frame 71. When it is necessary to release the fixation, push the control rod 81 to drive the baffle 83 to compress the compression spring 84 and deform it. The control rod 81 drives the snap-fit ​​lever 86 to be pulled out from the inside of the snap-fit ​​interface 73, stopping the fixation of the insert rod 72 and the push frame 71, thus completing the disassembly of the mountain-shaped clamp 10.

[0035] exist Figure 4 In the middle, the dynamic support assembly 4 includes a tube 41 and a first insert rod 42. The tube 41 is connected to the inner wall of the outer rod 2, and the first insert rod 42 is inserted into the inside of the tube 41. The first insert rod 42 is connected to the snap-fit ​​crank rod 86.

[0036] When the locking lever 86 moves, it drives the first insert rod 42 to extend and retract inside the insert cylinder 41, providing dynamic support for the movement of the other end of the locking lever 86 and providing stability for the movement of the locking assembly 8.

[0037] like Figure 2 As shown, in order to make the movement of the mountain-shaped clamp 10 on the outer wall of the outer rod 2 more stable, the outer rod 2 is connected to the mountain-shaped clamp 10 through the stabilizing component 6. The stabilizing component 6 includes a through tube 61, which is installed on the mountain-shaped clamp 10. The outer rod 2 is inserted into the inside of the through tube 61. The inner wall of the through tube 61 is integrally formed with a slider 62. The slider 62 is slidably connected to the outer rod 2 through a sliding groove 63, which is opened on the outer wall of the outer rod 2.

[0038] When the mountain-shaped clamp 10 slides, it drives the through tube 61 to move on the outer wall of the outer rod 2, and the slider 62 slides inside the slide groove 63, which limits and stabilizes the linear movement of the mountain-shaped clamp 10.

[0039] To increase the convenience of the control lever 81, a handle 11 is installed at the other end of the control lever 81. The handle 11 is a wide circle, which conforms to the habit of human hand operation.

[0040] The working principle of this utility model is explained below with reference to a preferred embodiment: During assembly, the outer rod 2 is connected to the inner rod 1, and the pusher frame 71 is pushed downward. The two ends of the pusher frame 71 push the connecting cylinder 91 downward to push the first connecting plate 52 and the second connecting plate 54 to move, thereby driving the second insert rod 72 to insert into the interior of the outer rod 2. After the first connecting plate 52 and the second connecting plate 54 are pushed into a flat state, the second connecting plate 54 pushes the mountain-shaped clamp 10 to move. The mountain-shaped clamp 10 clamps and pushes the tube body tightly, and the elasticity of the compression spring 84 pushes... The baffle 83 drives the control rod 81 to move, and the control rod 81 drives the snap-fit ​​lever 86 to snap into the inside of the snap-fit ​​interface 73, fixing the second insert rod 72 and the push frame 71, and also fixing the clamping of the tube body by the mountain-shaped clamp 10. When disassembly is required, simply press the control rod 81, push the control rod 81 to drive the baffle 83 to compress the spring 84, and the control rod 81 drives the snap-fit ​​lever 86 to be pulled out from the inside of the snap-fit ​​interface 73, stopping the fixing of the second insert rod 72 and the push frame 71, and stopping the clamping of the tube body by the mountain-shaped clamp 10.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
