Detailed Description
In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following detailed description will be given with reference to the accompanying drawings and specific embodiments. It is to be understood that the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention. Furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.
In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
As shown in fig. 1, an embodiment of the present invention provides a downward-turning bell-mouth three-way bridge connecting member, which includes a connecting member body 1, and is used for connecting a first bridge 2 installed in parallel with a second bridge 3 and needs to pass through the second bridge 3 downward. Wherein, horn mouth 4 has been seted up to the first end of connecting piece body 1, and horn mouth 4 can be for dog-ear transition in this embodiment, also can be for smooth transition, as long as can make things convenient for the construction of cable bending part, and manufacturing is convenient.
The two sides of the bell mouth 4 are provided with side plates 5, and the side plates 5 are preferably perpendicular to the symmetry axis of the connector body 1 in the embodiment. The side plates 5 are provided with first side bolt holes 6, the first bridge frame 2 is provided with a cutting opening 7, the plates on two sides of the cutting opening 7 are provided with second side bolt holes 8 corresponding to the first side bolt holes 6, the first side bolt holes 6 and the second side bolt holes 8 are fixed through bolts, and therefore the connecting piece body 1 is connected with the first bridge frame 2.
And the second end of the connector body 1 is lower than the first end, so that the connector body 1 can pass through the lower part of the second bridge 3 without interfering with the second bridge 3.
Meanwhile, the bottom plate 9 of the connecting piece body 1 extends outwards to form an extension part 10 and exceeds the plane of the bell mouth 4, the extension part 10 is provided with a first bottom bolt hole 11, the bottom of the first bridge frame 2 at the position of the cutting opening 7 is provided with a second bottom bolt hole 12 corresponding to the first bottom bolt hole 11, the first bottom bolt hole 11 and the second bottom bolt hole 12 are fixed through bolts, and the bottom plate 9 of the connecting piece body 1 is fixed with the bottom of the first bridge frame 2. Therefore, the problem of deformation and leakage at the seam of the bottom surface of the bridge tee after installation can be well solved, and the tee connection reliability is further improved.
Meanwhile, as shown in fig. 2, in the present embodiment, the connecting member body 1 has a three-stage bending structure and has two bending points. As a preferred embodiment, the maximum bending angle of the bending part in this embodiment is greater than 40 degrees, and since the maximum bending part is usually close to the first end of the connector body 1, i.e. the position of the bell mouth 4, when the bending angle is greater than 40 degrees, the installation condition of 10cm pitch of the straight-line trunk bridge can be satisfied.
