Abstract
The invention discloses an internal-expanding-type tubular busbar intermediate joint which is formed by an intermediate joint, expansion joints, a double-end screw rod, a turbine and a worm. The two ends of the intermediate joint are internally provided with the expansion joints respectively; the two ends of the double-end screw rod are engaged with center threaded holes of the expansion joints respectively; the middle portion of the double-end screw rod is fixedly connected with the turbine; the thread in the worm is engaged with the turbine; the inner wall aperture of the intermediate joint is of a gradually-changing structure, and dimension of the aperture close to the two ends is larger than that the dimension of the middle aperture; and each expansion joint is of a cone structure, and cross section diameter close to the port portion is larger than the cross section diameter close to the double-end screw rod portion. The inner wall aperture of the intermediate joint is designed to be in the gradually-changing structure, so that when the expansion joints expand, the contact area between the expansion joints and the inner wall of the intermediate joint is increased, better conductivity is achieved, and heat is not easy to accumulated; and meanwhile, the stress is large in the span installation process, and thus the joint portion does not sink.
Description
Technical field:
The present invention relates to a kind of pipe bus connection structure, particularly relate to the transition joint of a kind of internal-expansion type pipe bus.
Background technology:
The transition joint of existing internal-expansion type pipe bus, place an expansion joint respectively at the inner two-end part of transition joint, expansion joint is fixed with double threaded screw respectively, then the hole of a 5-6mm × 50-60mm is opened in the centre on transition joint surface, reach transition joint inside with fork spanner during swelling to pull double threaded screw and pull expansion joint to move to transition joint centre, reach swelling object.There is following shortcoming in similar structures: (1) fork spanner reaches transition joint inside and pulls double threaded screw, and each rotational angle is less, needs the longer operating time during swelling; (2) bore size on transition joint surface is comparatively large, affects water conservancy diversion; (3) during swelling, expansion joint and transition joint interior contact area less, conduct electricity work for a long time, easily produce fever phenomenon, cause potential safety hazard.(4) existing double threaded screw does not have auto-lock function, and the faint vibrations produced after the energising of pipe bus, easily cause transition joint and pipe bus contact site to occur gap, affect electric conductivity.
Summary of the invention:
The present invention is directed to above the deficiencies in the prior art, provide that a kind of contact area is large, contact-making surface is seamless, easy for installation, the transition joint of low-resistance internal-expansion type pipe bus is fallen.
For achieving the above object, the invention provides
The transition joint of internal-expansion type pipe bus, is made up of transition joint, expansion joint, double threaded screw, turbine, worm screw; Described transition joint two ends are built-in with expansion joint respectively; Described double threaded screw two ends are engaged with expansion joint screwed hole of centre respectively; Described double threaded screw centre is fixedly connected with turbine; On described worm screw, screw thread engages with turbine.
Preferably, in technical scheme, transition joint inwall aperture is grading structure, and the aperture size near two ends is greater than median pore radius size.
Preferably, in technical scheme, expansion joint is conical structure, is greater than the diameter of section size near double threaded screw position near port position diameter of section size.
Compared with prior art, the present invention has following beneficial effect:
(1) by transition joint inwall aperture is set to grading structure, make expansion joint when swelling, increase the contact area with transition joint inwall, electric conductivity is better, is not easy heating; In span installation process, stress is large simultaneously, and joint area can not sink.(2) die nut rotary worm only need be used during swelling can to reach the object of transition joint swelling, convenient installation.(3) by the reaction force of turbine, self-locking can be carried out to worm screw, prevent from occurring loosening in transport, use procedure.
Accompanying drawing illustrates:
Fig. 1 is invention overall structure schematic diagram;
Fig. 2 is invention worm gear arrangement schematic diagram;
Main Reference Numerals illustrates:
1-transition joint, 2-expansion joint, 3-double threaded screw, 4-turbine, 5-worm screw.
Embodiment:
Below the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of embodiment.
Clearly represent unless otherwise other, otherwise in whole specification and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or part, and do not get rid of other element or other part.
As shown in Figure 1-2, the transition joint of internal-expansion type pipe bus, is made up of transition joint 1, expansion joint 2, double threaded screw 3, turbine 4, worm screw 5; Described transition joint 1 two ends are built-in with expansion joint 2 respectively; Described double threaded screw 3 two ends are engaged with expansion joint 2 screwed hole of centre respectively; Described double threaded screw 3 centre is fixedly connected with turbine 4; On described worm screw 5, screw thread engages with turbine 4.
During work, pull die nut, worm screw 5 is driven to rotate, on worm screw 5, screw thread engages with turbine 4, and turbine 4 drives the expansion joint 2 at two ends to move to transition joint 1 center by double threaded screw 3, because the inwall aperture size of transition joint 1 coordinates completely with the conical size of expansion joint 2, can be reached both combine closely, contact area increases, and increases water conservancy diversion area, is not easy heating.By the reaction force of turbine 4, self-locking can be carried out to worm screw 5, prevent from occurring loosening in transport, use procedure.
Patent of the present invention have easy for installation, conduct electricity very well, simple operation and other advantages, there is great popularizing action.
The aforementioned description to concrete exemplary of the present invention is to illustrate and the object of illustration.These descriptions not want the present invention to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present invention and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present invention and various different selection and change.Scope of the present invention is intended to limited by claims and equivalents thereof.
