Description

Technical Field

[0001] The utility model relates to the technical field of connecting warm - through pipelines, and particularly relates to a connecting clamp for warm - through pipelines. Background Technique

[0002] A warm - through pipeline is a pipeline that transports heat energy through steam or hot water to the interior of a building for use, so as to meet the needs of people's production and life. During the construction of warm - through pipelines, the pipelines used are buried underground. During the laying of warm - through pipelines, connecting clamps are required to connect the warm - through pipelines together to form an integral unit for use.

[0003] For traditional connecting clamps for warm - through pipelines, when in use, the connection between two groups of warm - through pipelines is generally achieved by the connection between bolts and nuts. However, when the warm - through pipelines are buried underground, with the increase of the service time, the nuts are prone to rust, and it is not convenient to disassemble and assemble the connecting clamp when subsequent disassembly and assembly are required. Therefore, we propose a connecting clamp for warm - through pipelines to improve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a connecting clamp for warm - through pipelines to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A connecting clamp for warm - through pipelines, including a first warm - through pipeline, a first connecting frame is installed on one side of the first warm - through pipeline, a second connecting frame is arranged on one side of the first connecting frame, and a second warm - through pipeline is installed on one side of the second connecting frame. Both ends inside the second connecting frame are provided with chutes, sliders are movably arranged inside the chutes, a connecting ring is fixed on the outer side wall of the slider, a sealing cover is movably arranged on the outer side wall of the connecting ring, a threaded seat is arranged on one side of the sealing cover, and the threaded seat is fixed to the left side of the outer side wall of the second connecting frame.

[0006] Preferably, the cross - section of the chute is larger than the cross - section of the slider, and a sliding structure is formed between the chute and the slider.

[0007] Preferably, the inner side wall of the sealing cover is uniformly provided with internal threads, the outer side wall of the threaded seat is uniformly provided with external threads, and a threaded connection is formed between the sealing cover and the threaded seat.

[0008] Preferably, a threaded post is fixed to the right side of the first connecting frame, and a nut is movably arranged on the outer side wall of the threaded post. A hole body is arranged on the left side inside the second connecting frame.

[0009] Preferably, there are four groups of threaded posts, and the four groups of threaded posts are annularly distributed on one side of the first connecting frame.

[0010] Preferably, fixing rings are hingedly installed at both the front and rear ends of the outer side wall of the first connecting frame. One end of each fixing ring is provided with a groove body, and the groove body is arranged inside the second connecting frame. A limiting plate is hingedly installed on one side inside the groove body.

[0011] Preferably, the cross-section of the limiting plate is smaller than that of the groove body, and a clamping structure is formed between the limiting plate and the groove body.

[0012] Preferably, two groups of fixing rings and limiting plates are provided, and a clamping structure is formed between the fixing rings and the limiting plates.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: This connecting fixture for the heating pipeline not only protects the nut and bolt from rust, which may affect subsequent disassembly and assembly, but also facilitates quickly connecting two heating pipelines together. Moreover, the connecting fixture greatly increases the stability of the assembly between the heating pipelines.

[0014] (1) By providing components such as a sealing cover, a connecting ring, and a threaded seat, after the connecting fixture connects the first heating pipeline and the second heating pipeline together, the sealing cover can be rotated to be threadedly connected with the threaded seat, thereby forming a protection on the outer side walls of the nut and the threaded column of the connecting fixture, avoiding rust damage to the nut and the threaded column caused by moisture in the soil when the heating pipeline is buried underground.

[0015] (2) When using this connecting fixture, after fitting the first connecting frame and the second connecting frame together, it is necessary to pass the fixing parts through the first connecting frame and the second connecting frame one by one for locking, which is a time-consuming operation. By fixing the threaded column on one side of the first connecting frame, when the first connecting frame and the second connecting frame are fitted together, the threaded column on one side of the first connecting frame can be passed through the hole body inside the second connecting frame together, so that the fixing parts can be passed through the first connecting frame and the second connecting frame at one time, greatly increasing the assembly efficiency of the first connecting frame and the second connecting frame and making it more convenient to use.

[0016] (3) After the first connecting frame and the second connecting frame are connected together to assemble the first heating pipeline and the second heating pipeline into a whole, the fixing ring can be turned over and engaged with the limiting plate, thereby strengthening the connection between the first connecting frame and the second connecting frame, and greatly increasing the stability of the connection between the first heating pipeline and the second heating pipeline, making the connection more firm.

And the threaded seat 9 is fixed to the left side of the outer side wall of the second connecting frame 5. The cross - section of the slide groove 14 is larger than the cross - section of the slide block 15. A sliding structure is formed between the slide groove 14 and the slide block 15. The inner side wall of the sealing cover 7 is evenly provided with internal threads. The outer side wall of the threaded seat 9 is evenly provided with external threads. A threaded connection is formed between the sealing cover 7 and the threaded seat 9, and the sealing cover 7 is stably pushed to be connected with the threaded seat 9;

[0024] Specifically, as shown in Figure 1 and Figure 2 , after the first connecting frame 2 and the second connecting frame 5 are connected together, rotate the sealing cover 7. The sealing cover 7 is pushed to move to one side by the sliding of the slide block 15 inside the slide groove 14, so that the connecting ring 8 is threadedly connected with the threaded seat 9, thereby forming a sealing protection on the outer side walls of the nut 3 and the threaded column 4 to prevent substances in the soil from rusting and damaging the nut 3 and the threaded column 4.

[0025] Embodiment 2: A threaded post 4 is fixed to the right side of the first connecting frame 2, and a nut 3 is movably arranged on the outer wall of the threaded post 4. A hole body 10 is arranged on the left side inside the second connecting frame 5. There are four groups of threaded posts 4, and the four groups of threaded posts 4 are annularly distributed on one side of the first connecting frame 2, so that the first connecting frame 2 and the second connecting frame 5 are tightly clamped together;

[0026] Specifically, as Figure 1 shown, after the first connecting frame 2 is installed on the outer wall of the first heating pipeline 1 and the second connecting frame 5 is installed on the outer wall of the second heating pipeline 6, the threaded posts 4 on one side of the first connecting frame 2 are aligned with the hole bodies 10 inside the second connecting frame 5 and then snapped in together, so as to assemble the first connecting frame 2 and the second connecting frame 5. Then, the nuts 3 are sequentially screwed onto the outer walls of the threaded posts 4 to assemble the first connecting frame 2 and the second connecting frame 5.

[0027] Embodiment 3: Fixed rings 13 are hingedly installed at both the front and rear ends of the outer wall of the first connecting frame 2.
