Description

Technical Field

[0001] The utility model relates to the technical field of pipeline structures, in particular to an electrical bridge pipe fitting. Background Art

[0002] At present, the laying of circuits in residential buildings generally adopts the concealed laying method, that is, the wiring is carried out by pre-buried wire pipes in the walls of buildings or on the ground. However, with the development of science and technology and economy, the types and quantities of household electrical appliances are increasing, and the number of lines required to be laid in buildings is also increasing, which leads to the inevitable crossing of lines. Bridge elbow fittings can meet the needs of circuit crossing layout.

[0003] In the prior art, the bridge bends used for circuit cross-layout are generally of the leaping type, that is, one circuit goes straight while the other circuit is avoided by the bridge bend. This method will result in a relatively high overall height of the circuit pipes around the bridge and require deeper grooves to be cut in the wall or the ground, which can easily damage the strength of the house wall, leading to increased construction costs and the existence of safety risks.

[0004] Chinese utility model patent CN209389607U provides an integrated electromagnetic interference metal bridge bend, including the bridge bend body consisting of a first elbow, a second elbow, a socket, a chamfer and an arched section, the first elbow consisting of a first straight section and a first arced section, one end of the first straight section is connected to the first arced section, the second elbow consisting of a second straight section and a second arced section, one end of the second straight section is connected to the second arced section, the socket consisting of a first socket and a second socket, one end of the first straight section is provided with a first socket, one end of the second straight section is provided with a second socket, the chamfer includes a first chamfer and a second chamfer, a first chamfer is provided between the first straight section and the first socket, a second chamfer is provided between the second straight section and the second socket, and an arched section is provided between the first elbow and the second elbow. This patent is conducive to solving the problem of cross layout of wire lines and avoiding separate routing, but it cannot solve the problem that the overall height of the circuit pipeline at the bridge bend is high, and due to the high overall height of the pipeline, the pipeline needs to be grooved deeper when it is concealed.

[0026] Example 1

[0027] Please refer toFigure 1 A kind of electrician's cross - bridge pipe fitting in the preferred embodiment of the utility model comprises an upper pipe fitting 1, a lower pipe fitting 2 and a connecting piece 3. The upper pipe fitting 1 and the lower pipe fitting 2 are arranged crosswise, and the upper pipe fitting 1 and the lower pipe fitting 2 are connected by the connecting piece 3. A first concave part 101 is arranged in the middle of the upper pipe fitting 1, and a second concave part 201 is arranged in the middle of the lower pipe fitting 2. The openings of the first concave part 101 and the second concave part 201 face each other. This embodiment is a split - type design. The upper pipe fitting and the lower pipe fitting are arranged crosswise, and both the middle parts of the upper pipe fitting and the lower pipe fitting are provided with concave parts. The openings of the concave parts of the upper pipe fitting and the lower pipe fitting facing each other can reduce the overall cross - bridge thickness of the cross - bridge pipe fitting, solve the problem that the overall height of the circuit is relatively high at the cross - bridge bend of the circuit cross - layout and the grooving depth is relatively deep, and is beneficial to reducing the construction cost and safety risk.

[0028] Furthermore, the first concave part 101 and the second concave part 201 in this embodiment are of arc structures, which is beneficial to the smooth threading of the cable and prevents damage to the insulating layer of the wire pipe.

[0029] Furthermore, the arc structures of the first concave part 101 and the second concave part 201 are circular arcs, and the design radius of the circular arc is 800 mm.

[0030] Please refer to Figure 1 , the upper pipe fitting 1 and the lower pipe fitting 2 in this embodiment are rotatably connected by the connecting piece 3.

[0031] Furthermore, the connecting piece 3 further comprises limiting rings 303 arranged on both sides of the lower pipe fitting 2 and a rotation limiting block 301 arranged in the first concave part. The limiting rings 303 are semi - rings, and limiting rings 303 are arranged on both sides of the lower pipe fitting 2. The two ends of the limiting rings 303 are respectively connected to the outer pipe walls of the lower pipe fitting 2. The rotation limiting block 301 slides along the side of the limiting ring 303 close to the lower pipe fitting 2 so that the included angle formed by the upper pipe fitting 1 and the lower pipe fitting 2 is 45° - 135°, which is beneficial to the adjustment of the installation angle.

[0032] Even further, please refer to Figure 2 and Figure 3 , the connecting piece 3 further comprises an upper limiting block 302, and a lower limiting block 304 is arranged on the second concave part 201. The upper surface of the upper limiting block 302 is connected to the upper surface of the lower limiting block 304. This connection can not only assist the rotation of the pipe fitting but also prevent the rotation limiting block 301 from disengaging from the limiting ring 303.

[0033] Furthermore, please refer to Figure 4 , a layer of metal shielding layer 6 is arranged between the inner wall 5 and the outer wall 7 of the pipe fittings of the upper pipe fitting 1 and the lower pipe fitting 2, which can effectively reduce the interference caused by the electromagnetic field radiation generated when the cable is energized to the weak - current signal line.

[0034] Further, the upper pipe fitting 1 and the lower pipe fitting 2 of this embodiment are square pipe fittings, and adapter joints 4 are provided at both ends. Through these adapter joints 4, connection with other wire pipes can be achieved.

[0035] Further, the first connection portion 401 of this adapter joint 4 is a cuboid, and the first connection portion 401 is used to connect with the upper pipe fitting 1 or the lower pipe fitting 2. The second connection portion 402 is cylindrical, and the second connection portion 402 is used to connect with other wire pipes. The adapter joint 4 in this embodiment further includes a third connection portion 403. The third connection portion 403 is a frustum with one base being rectangular and the other base being circular, which expands the wire threading space, is conducive to the smooth threading of the cable, and prevents the cable from getting stuck at the turning point of the connection portion.

[0036] Embodiment 2

[0037] The difference between this embodiment and Embodiment 1 is that, on the basis of Embodiment 1, this embodiment further describes the shape of the concave portions of the upper pipe fitting 1 and the lower pipe fitting 2.

[0038] Based on the electrician's cross-over pipe fitting described in Embodiment 1, in this Embodiment 2, the arc-shaped concave portions of the upper pipe fitting 1 and the lower pipe fitting 2 are further designed as gradually changing arc-shaped concave portions with a design radius of 1000 mm, and the wire threading is smoother.

[0039] The other structures of this embodiment are the same as those of Embodiment 1, and will not be elaborated here.

[0040] Embodiment 3

[0041] The difference between this embodiment and Embodiment 2 is that, on the basis of Embodiment 2, this embodiment further describes the shape and connection of the rotation limiting block 301 and the limiting ring 303.

The inner ring surface of the limiting ring 303 facing the lower pipe fitting 2 is provided with a snap groove 305 and the rotation limiting block 301 is an L-shaped snap protrusion 306. Inserting the snap protrusion 306 into the snap groove 305 can not only form a snap connection to further prevent the upper and lower pipe fittings from separating, but also enable the snap protrusion 306 part of the limiting block 301 to slide along the snap groove 305 of the limiting ring 303.

[0043] The other structures of this embodiment are the same as those of Embodiment 2, and will not be elaborated here.

[0044] In summary, the embodiment of the present utility model provides an electrician's cross-over pipe fitting. By designing the upper pipe fitting 1 and the lower pipe fitting 2 as square pipes with circular arc depressions and making the openings of the first depression 101 and the second depression 201 face each other, the overall cross-over height of the cross-over pipe fitting is reduced, effectively solving the problem that the overall height of the circuit at the cross-over bend in the cross-circuit layout is relatively high and the grooving depth is relatively deep, and reducing the construction cost and safety risk. In the embodiment of the present utility model, the pipe walls of the upper pipe fitting 1 and the lower pipe fitting 2 are also designed with metal shielding layers, which can reduce the influence of electromagnetic radiation generated when the cable is energized on the weak current signal line.
