Description

Technical Field

[0001] The utility model relates to the technical field of building electrical engineering, in particular to a pre-buried electrical conduit overlapping connector. Background Art

[0002] With the development of modern technology, more and more electrical equipment is used in buildings. Therefore, more and more pre-buried pipelines are required for building electrical systems, which leads to the inevitable cross-overlapping of different conduits in the pre-buried electrical conduits, or even the overlapping of multiple layers of conduits.

[0003] The design thickness of existing floor slabs is generally 80-150mm, while the spacing of electrical conduits pre-buried in the space between the bottom ribs and the surface ribs is smaller, about 30-100mm. In particular, the spacing of electrical conduits in the floor can be even smaller when using prefabricated composite floor slab assembly structures. The outer diameter of electrical conduits is generally about 20mm. When two conduits are cross-overlapped, the conduit height will exceed 40mm. When three layers overlap at the same place, the conduit height may exceed 60mm. In order to ensure that the floor slabs and walls have sufficient strength, it is necessary to intervene and control the overlap of the conduits through the pre-buried electrical conduit overlap connector to limit the overlap height.

[0004] However, some of the current pre-buried electrical conduit overlapping connectors are designed to cope with the situation where the conduit has limited orientations and there are multiple conduits in a single orientation. It is difficult to adapt to the situation where there are conduits in multiple orientations at one electrical conduit overlapping point, and it is necessary to design a connector structure for conduit overlapping points with multiple orientations.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figures 1 to 5, in the embodiment of the present utility model, a buried electrical conduit laminated connector includes a fixing frame 1. A plurality of movable pipe connectors 2 are slidably clamped at the edge of the fixing frame 1. The movable pipe connectors 2 are fixedly connected to the two ends of the electrical conduit 3. The fixing frame 1 includes a first side plate 101. A plurality of connecting bolts 104 are inserted and installed at equal angles in a ring shape near the edge of the first side plate 101. One end of the connecting bolt 104 is screwed with a connecting column 108. Each connecting column 108 is fixedly installed at equal angles in a ring shape on the rear surface near the edge of the second side plate 107. Chutes 102 are opened on the front surface edge of the first side plate 101 and the rear surface edge of the second side plate 107.

[0026] Specifically, apply the overall connector to the laminated part of multiple conduits. Select an appropriate number of movable pipe connectors 2 according to the number of conduits to be connected. Clamp the two sides of the movable pipe connectors 2 with the chutes 102 at the first side plate 101 and the second side plate 107. Pass the connecting bolts 104 through the first side plate 101 and screw them into the connecting columns 108 to connect the two side plate structures to form the overall fixing frame 1. Slide and clamp each movable pipe connector 2 at the edge of the overall fixing frame 1. According to the positions of the pre-buried conduits in different directions, move each movable pipe connector 2 to make the positions of each movable pipe connector 2 correspond to the directions of each pre-buried conduit. Finally, during installation, two movable pipe connectors 2 are grouped together and screwed and connected to the pipe openings at the edge of the fixing frame 1 of a single pre-buried pipe. It can freely adjust each movable pipe connector 2 within a certain range according to the actual direction of the pre-buried conduit to cope with the actual situations at the docking parts of various different pre-buried conduits, and has extremely high adaptability.

[0027] Embodiment 1

[0028] As Figures 1 - 4 shown, in this embodiment, a plurality of locking screw holes 103 are opened at equal angles in a ring shape on the side surfaces of the first side plate 101 and the second side plate 107; the movable pipe connector 2 includes a base plate 201. A pipe interface 202 is fixedly inserted and installed in the up and down direction of the base plate 201. Limiting pieces 203 are fixedly installed on both sides of the base plate 201. A sliding edge 204 is fixedly installed on one side of the limiting piece 203. A locking screw piece 205 is fixedly installed on the upper side surface of the sliding edge 204. The locking screw piece 205 is an L-shaped structure; the sliding edges 204 on both sides of the base plate 201 are respectively slidably clamped with the chutes 102 opened at the first side plate 101 and the second side plate 107.

[0029] In this embodiment, when adjusting the position of each movable pipe port 2, the sliding edge 204 slides in the sliding groove 102, and the locking screw 205 slides along the side surface of the No. 1 side panel 101 or the No. 2 side panel 107. When it is adjusted to the appropriate position, the flat head screw is passed through the locking screw 205 and screwed into the locking screw hole 103 to tighten the position. It should be noted that when the position of the movable pipe port 2 is awkward and the locking screw hole 103 is not aligned with the locking screw hole 103, as the flat head screw is tightened, the flat head is tightly against the side surface of the side panel, relying on friction to provide stability. At the same time, in conjunction with the pipe fixing frame for installing the pre-buried conduit itself, it can also provide sufficient stability to the interface.

[0030] like Figures 1 - 3 As shown, in this embodiment, a Velcro patch 105 is fixedly installed on the front surface of the No. 1 side panel 101, and a Velcro female patch 106 is attached to the front surface of the Velcro patch 105. The Velcro patch 105 is disc-shaped, and the Velcro female patch 106 is strip-shaped. An adjustment port 109 is inserted in the middle of the No. 2 side panel 107, and a sealing plate 110 is screwed on the adjustment port 109. The front surface of the sealing plate 110 has force grooves 111 symmetrically provided.

[0031] In specific implementation, after the fixing frame 1, the movable pipe port 2 and the electrical conduit 3 are assembled, the arrangement of the rubber hoses 304 inside the fixing frame 1 can be adjusted by adjusting the port 109. The adjusted rubber hoses 304 are wrapped around the side walls through the Velcro mother patch 106 and attached to the Velcro mother patch 106, and the positions of the rubber hoses 304 are relatively limited to ensure that the upper limit of the overlapping point of each electrical conduit 3 inside the fixing frame 1 is only the width of the diameter of two rubber hoses 304. At the same time, the actual gap between the No. 1 side plate 101 and the No. 2 side plate 107 is also only the width of the outer diameter of two electrical conduits 3, so as to limit the upper limit of the conduit overlap and avoid excessive thickness at the overlapping part of the conduits. After the adjustment is completed, the sealing plate 110 is screwed on to seal the adjustment port 109.

[0032] Embodiment 2

[0033] On the basis of the first embodiment, in order to supplement the specific installation method of the electrical conduit 3 which is not mentioned in the first embodiment, the specific connection method with the movable pipe port 2 is described.

[0034] like Figures 4 - 5 As shown, in this embodiment, the electrical conduit 3 includes a screw mouth 301, a connecting port 302 is rotatably installed on the bottom side of the screw mouth 301, a fastening screw ring 303 is screwed installed on the side surface of the connecting port 302, and the conical groove between the lower edge of the outer surface of the connecting port 302 and the lower edge of the inner surface of the fastening screw ring 303 is clamped with the pipe mouth of the rubber hose 304; the screw mouths 301 installed at both ends of the rubber hose 304 are screwed and connected with the pipe interface 202 on the inner side of the substrate 201.

[0035]

[0035] When specifically implemented, when arranging the electrical conduit 3 inside the fixing frame 1, first cut a rubber hose 304 with a suitable length according to the required length of the electrical conduit 3. Sleeve the fastening screw ring 303 on the outer surface of the rubber hose 304, insert the connection port 302 into the inner wall of the pipe orifice of the rubber hose 304, slide and rotate the fastening screw ring 303 to screw the connection port 302 and the fastening screw ring 303 together, and clamp and fix the edge of the pipe orifice of the rubber hose 304. Install the screw ports 301 at both ends of the rubber hose 304, and then screw the screw ports 301 and the inner pipe interface 202 of the substrate 201 together, so that a suitable electrical conduit 3 can be freely assembled according to actual needs, further improving the adaptability of the overall structure.
