Description

Technical Field

[0001] This utility model relates to the field of electromechanical pipeline installation technology, specifically to an electromechanical pipeline installation and connection device for prefabricated buildings. Background Technology

[0002] Building electromechanical pipelines are pipelines and supporting components that run through the interior of a building and carry core functions such as water supply and drainage, electricity, and heating, ventilation and air conditioning. Electromechanical pipelines mainly include water supply and drainage pipelines, which transport domestic water, sewage and fire-fighting water, and secondly electrical pipelines, which cover power, lighting, communication and monitoring pipelines.

[0003] Chinese Patent Publication No. CN218040631U discloses a prefabricated building electromechanical pipeline installation and connection device, relating to the field of pipeline installation technology. This utility model includes a first connecting pipe and a second connecting pipe. Two sets of first and second slots are formed on one side wall of the first connecting pipe. The second slot is connected to the first slot at a 90-degree angle. A first groove penetrates the inner surface of the first slot, and a second groove penetrates the inner surface of the second slot. Two sets of inserts are fixedly connected to one side wall of the second connecting pipe. A spring groove is formed on the upper surface of the second insert, and a memory spring is connected to the inner surface of the spring groove. A locking block is connected to one end of the memory spring, and the position of the locking block is adapted to both the first and second grooves. This utility model, by setting up a first connecting pipe, a second connecting pipe, inserts, first slots, and second slots, achieves rapid assembly of the second connecting pipe and the first connecting pipe, greatly improving the assembly flexibility between connecting pipes, and is suitable for corners and walls.

[0004] In the aforementioned prior art, the splicing of two connecting pipes can be used to install building electromechanical pipelines at the corner of the wall. However, the length of the device is fixed, while the space size of the installation area varies. If the connecting pipe is too long, the end needs to be cut. After the two sets of connecting pipes are cut, it is difficult to splice them together again, which affects the stability.

[0005] Therefore, it is necessary to propose an installation and connection device for electromechanical pipelines in prefabricated buildings to solve or at least alleviate the above-mentioned defects. Utility Model Content

[0006] The purpose of this utility model is to provide an installation and connection device for electromechanical pipelines in prefabricated buildings to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated building electromechanical pipeline installation and connection device, including a corner bracket and a splicing bracket. The corner bracket and the splicing bracket are detachably installed with the same U-shaped connecting plate. A positioning structure is connected to the U-shaped connecting plate. A lead screw is rotatably installed inside the U-shaped connecting plate. A fine-tuning structure is connected to the lead screw. Both the corner bracket and the splicing bracket are connected with pipeline separation structures inside.

[0008] Preferably, the positioning structure is arranged in two sets, each set of positioning structure includes two slide rods, the two slide rods are symmetrically slidably installed inside the U-shaped connecting plate, and two threaded holes are opened inside the two slide rods. Several positioning holes are opened on the corner bracket and the splicing bracket, and a bolt is installed in the corresponding threaded hole. The bolt is inserted into the corresponding positioning hole.

[0009] Preferably, the fine-tuning structure includes a knob, which is installed at one end of a lead screw. A threaded slide is threaded onto the lead screw, and two connecting rods are rotatably mounted on the threaded slide. One end of each connecting rod is rotatably mounted on one side of the two slides that are close to each other.

[0010] Preferably, guide grooves are provided on the inner walls of both sides of the slide rod, and guide sliders are slidably installed in both guide grooves, with the two guide sliders respectively installed on both sides of the slide rod.

[0011] Preferably, the threaded slide has a threaded hole inside, and the lead screw is threaded into the threaded hole.

[0012] Preferably, the pipeline separation structure includes a branch seat 1 and a branch seat 2. The branch seat 2 is located above the branch seat 1. Both the branch seat 1 and the branch seat 2 have several pipeline grooves and several threaded holes 2 inside. The branch seat 1 has a bolt 2 installed in its internal thread, and the branch seat 2 has a bolt 3 installed in its internal thread. The corner bracket has several threaded holes 3 inside, and one end of the bolt 2 is threaded into the corresponding threaded hole 3.

[0013] Preferably, a cover plate is detachably installed on one side of the branch connector 2, and a bolt 4 is inserted inside the cover plate. One end of the bolt 4 is threaded into the corresponding threaded hole 2, and the bolts 4, 3 and 2 are arranged alternately.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) In this utility model, when splicing pipeline brackets, the U-shaped connecting plate can be placed inside the corner bracket and the splicing bracket. After aligning the positioning hole, the bolt can be screwed in to complete the fixation. When the splicing bracket is too long and does not fit the size of the installation space, it can be cut according to the requirements. After cutting, the distance between the positioning holes of the splicing bracket and the corner bracket will change. By rotating the knob of the micro-adjustment structure, the screw can be driven to rotate. The screw drives the threaded slide to move, and then pushes the slide along the guide groove through the connecting rod to achieve precise adjustment of the slide distance. This ensures that the threaded hole on the slide can always be precisely aligned with the positioning hole of the bracket after cutting, so that splicing can be achieved after cutting and adapt to different installation spaces.

[0016] (2) When there are a large number of pipelines, the second branch seat can be stacked on top of the first branch seat and fixed by the third bolt to form a multi-layer partition structure. Each layer of pipeline grooves independently places the pipelines to avoid tangling and crossing. The top layer is limited by the cover plate to prevent the pipelines from loosening. The stacked design can flexibly increase or decrease the number of partition layers according to the number of pipelines, maximize the use of the internal space of the bracket, and adapt to pipeline layout requirements of different complexity.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figure 1-4This utility model provides a technical solution: a prefabricated building electromechanical pipeline installation and connection device, including a corner bracket 100 and a splicing bracket 101. The corner bracket 100 and the splicing bracket 101 are detachably installed with the same U-shaped connecting plate 200. A positioning structure is connected to the U-shaped connecting plate 200. A lead screw 300 is rotatably installed inside the U-shaped connecting plate 200. A fine adjustment structure is connected to the lead screw 300. Both the corner bracket 100 and the splicing bracket 101 are connected with pipeline separation structures.

[0026] In this implementation scheme, the initial docking of the corner bracket 100 and the splicing bracket 101 is achieved by using the U-shaped connecting plate 200 in conjunction with the positioning structure. If the spacing of the positioning holes 203 changes after the splicing bracket 101 is cut, the spacing of the slide rod 201 is adjusted by the fine-tuning structure to match the position of the positioning holes 203, thereby completing the stable splicing. Finally, the pipeline separation structure is used to classify and fix different pipelines, thereby achieving the orderly installation of electromechanical pipelines.

[0027] Specifically, there are two sets of positioning structures. Each set of positioning structures includes two slide rods 201. The two slide rods 201 are symmetrically slidably installed inside the U-shaped connecting plate 200. The interior of each slide rod 201 has two threaded holes 202. The corner bracket 100 and the splicing bracket 101 are provided with several positioning holes 203. The corresponding threaded holes 202 are threaded with bolts 204, which are inserted into the corresponding positioning holes 203.

[0028] In this embodiment, during splicing, the corner bracket 100 is placed in the corner of the wall, the splicing bracket 101 is placed to the side of the corner bracket 100, and then the U-shaped connecting plate 200 is placed inside the two, so that the threaded hole 202 on the slide rod 201 is aligned with the positioning hole 203 on the bracket, and the bolt 204 is passed through the positioning hole 203 and screwed into the threaded hole 202, thus completing the connection and fixation of the corner bracket 100, the splicing bracket 101 and the U-shaped connecting plate 200.

[0029] Specifically, the fine-tuning structure includes a knob 301, which is installed at one end of a lead screw 300. A threaded slide block 302 is threaded onto the lead screw 300. Two connecting rods 303 are rotatably mounted on the threaded slide block 302. One end of each connecting rod 303 is rotatably mounted on one side of each slide rod 201 that is close to each other. Guide grooves 304 are provided on the inner walls of both sides of the slide rod 201. Guide sliders 305 are slidably installed in each of the two guide grooves 304. The two guide sliders 305 are respectively installed on both sides of the slide rod 201. A threaded hole 306 is provided inside the threaded slide block 302, and the lead screw 300 is threaded into the threaded hole 306.

[0030] In this embodiment, when the splicing bracket 101 is cut too long, the distance between it and the positioning hole 203 on the corner bracket 100 changes. At this time, rotating the knob 301 drives the lead screw 300 to rotate. The lead screw 300 drives the threaded slide block 302 to move vertically through the threaded engagement with the threaded hole 306. The threaded slide block 302 drives one end of the two connecting rods 303 to rotate and move, so that the connecting rods 303 push or pull the two slide bars 201 closer or further away from each other. When the slide bars 201 move, the guide slider 305 slides in the guide groove 304, restricting the direction of movement of the slide bars 201 and ensuring that the threaded hole 202 on the slide bar 201 is accurately aligned with the adjusted positioning hole 203 position.

[0031] Example 2: As Figure 1-4 The pipeline separation structure includes a first branch seat 400 and a second branch seat 401. The second branch seat 401 is located above the first branch seat 400. Both the first branch seat 400 and the second branch seat 401 have several pipeline grooves 402 and several threaded holes 403 inside. The second branch seat 400 has a bolt 404 threaded inside, and the second branch seat 401 has a bolt 405 threaded inside. The corner bracket 100 has several threaded holes 406 inside. One end of the bolt 404 is threaded into the corresponding threaded hole 406. A cover plate 407 is detachably installed on one side of the second branch seat 401. A fourth bolt 408 is inserted inside the cover plate 407. One end of the fourth bolt 408 is threaded into the corresponding threaded hole 403. The fourth bolt 408, the third bolt 405 and the second bolt 404 are arranged alternately.

[0032] In this embodiment, during installation, the first branch connector 400 is first fixed with bolt 404. Bolt 404 is then screwed into the threaded hole 403 of the branch connector 400 and the threaded hole 406 of the bracket. The installation position of the branch connector 400 can be adjusted by selecting different threaded holes 406. The pipeline is placed into the pipeline groove 402 of the branch connector 400, and then the second branch connector 401 is placed on top. It is fixed by screwing bolt 405 into the threaded holes 403 of both. The second branch connector 401 not only prevents the pipeline in the branch connector 400 from coming loose, but its own pipeline groove 402 can also accommodate more pipelines. The branch connectors can be stacked as needed. Finally, the cover plate 407 is placed on top of the second branch connector 401 and fixed with bolt 408 to limit the pipeline at the top. The staggered arrangement of the bolts can avoid mutual interference and ensure a stable installation.

[0033] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
