Referring to fig. 2 and 3, a stopper 114 is provided at one of the first clamping plate 110 and the second clamping plate 120, and a stopper groove 124 is provided at the other. The limiting block 114 is slidably matched with the limiting groove 124, and the limiting block 114 and the limiting groove 124 are used for limiting in the height direction of the first clamping plate 110 and the second clamping plate 120, so that the first clamping groove 111 and the second clamping groove 121 are located at the same horizontal height, and the two rail bodies 20 are located at the same height.
In this embodiment, the stopper 114 may be provided to the first clamping plate 110 and the stopper groove 124 may be provided to the second clamping plate 120. The limiting block 114 is located at the first mating surface 112, and the limiting block 114 and the first clamping groove 111 are respectively located at two opposite sides of the first clamping plate 110. The limiting block 114 includes an abutting surface, and the abutting surface is parallel to the length direction of the first clamping groove 111. The limiting groove 124 is disposed at a position on the second clamping plate 120 corresponding to the limiting block 114, and a sidewall of the limiting groove 124 is in abutting engagement with the abutting surface. Thus, after the installation, the upper and lower sides of the second clamping plate 120 can be respectively limited by the rail body 20 and the limiting block 114, so that the pressure applied to the connecting piece 130 is reduced. Of course, the positioning of the stopper 114 on the first clamping plate 110 and the positioning of the stopper groove 124 on the second clamping plate 120 are only one implementation of the present embodiment, and in another implementation, the stopper 114 may be positioned on the second clamping plate 120 and the stopper groove 124 may be positioned on the first clamping plate 110.
When the existing rail bodies 20 are connected, at least one rail body 20 of each conductive rail anchor section is of a nonstandard length, and the rail bodies 20 need to be cut on site. The intermediate joint needs to be perforated in situ after cutting, and at least two holes are needed at each position. Generally, about 30% of the whole conduit rail has rail bodies 20 which need to be perforated on site (about 40-60 perforations per km of rail body 20), the construction amount is large, and the cleaning on site is difficult to ensure. Especially, the side current-feeding lines are overhead lines, so that the on-site punching difficulty is higher and the hole position accuracy is lower. In addition, the installation of other components such as the electrical connection needs to be perforated on site, and once the installation position is not easy to change after perforation, the operation difficulty of later maintenance and replacement of the rail body 20 is greater.
Referring to fig. 4, based on the above, an embodiment of the present utility model also discloses an adjustable intermediate joint assembly 10, including a fixed structure 200 and two adjustable intermediate joint units 100 as described above. The two adjustable intermediate connector units 100 form a releasable fit by means of the fixed structure 200.
The adjustable middle joint assembly 10 according to the present embodiment is a buckle type structure, and the symmetrical pair of first clamping plates 110 and second clamping plates 120 and the fixing structure 200 for connecting the two sets of adjustable middle joint units 100 together form a complete set of adjustable middle joint assembly 10. The movement of the two end rail bodies 20 relative to the thickness direction is realized by means of the relative movement of the first clamping plate 110 and the second clamping plate 120, so that the flow-imparting surfaces 21 of the two end rail bodies 20 are completely aligned and coplanar, and the defect that the flow-imparting surfaces 21 at the two ends of the joint of the rail bodies 20 are not coplanar due to the thickness dimension deviation in the manufacture of the rail bodies 20 is overcome. After alignment, the first clamping plate 110 and the second clamping plate 120 are tightened by the fixing structure 200 to achieve mechanical connection and smooth electrical connection of the rail body 20. The first clamping plate 110 and the second clamping plate 120 have larger cross-sectional areas, so that the first clamping plate 110 and the second clamping plate 120 have stronger conductivity and better joint rigidity, the first clamping groove 111 and the second clamping groove 121 are matched with the rail body 20, the first clamping plate 110 and the second clamping plate 120 generate large enough biting force on the rail body 20, and the contact area between the first clamping plate 110 and the second clamping plate 120 and the rail body 20 can be increased through the first clamping groove 111 and the second clamping groove 121, so that the connection effect and the current conduction effect are guaranteed. In addition, the adjustable middle joint assembly 10 disclosed in this embodiment can eliminate the step of punching holes in the rail body 20, reduce the manufacturing cost, reduce the workload of installation and construction, and facilitate the later maintenance and replacement. The adjustable intermediate joint assembly 10 is limited by the cross-sectional shape and line limits of the rail body 20, can have larger cross-sectional area, and has stronger downloading current capacity and higher joint connection strength and rigidity.
By changing the configuration of parts, the device can be used for intermediate connectors and also can be used as components such as power-on connection, lightning conductor connection or grounding connection.
Wherein the fixing structure 200 includes a bolt and a nut. The bolts are respectively connected with the two first clamping plates 110, and nuts are installed at one ends of the bolts after passing through the two first clamping plates 110. By tightening the bolts, the two first clamping plates 110 can be brought close to each other, thereby restricting the rail body 20.
In order to enhance the connection stability of the two adjustable middle joint units 100, the above-described fixing structure 200 may be provided between the two second clamping plates 120.
With reference to fig. 5 and 6, an embodiment of the present utility model also discloses a conductor rail system comprising an adjustable intermediate joint assembly 10 as described above and two rail bodies 20. The two adjustable middle joint units 100 are respectively located at the upper side and the lower side of the rail body 20, one rail body 20 is clamped between the two first clamping grooves 111, and the other rail body 20 is clamped between the two second clamping grooves 121.
In addition, other parts can be added on at least one group of adjustable middle joint units 100 to be used as other components such as power-on connection, lightning conductor connection or ground wire connection, and the like, so that the universal joint has stronger universality.
The foregoing is merely a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and variations may be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
