Detailed Description

The invention will be further explained by means of specific embodiments with reference to the drawings, in which:

see figure 1, an embodiment of rotation conductor spacer sectional fixture, including connecting block 1, bracing piece 2 and top tight mechanism, bracing piece 2 is equipped with two and rotates the relative both ends of connecting block 1, and the middle part at connecting block 1 is connected to the tight mechanism in top, and bracing piece 2 is used for pressing from both sides tight in the end both sides of conductor spacer, and the tight mechanism in top is used for pushing up the end top at the conductor spacer.

Specifically, as shown in fig. 2 and 3, the connecting block 1 may be a long strip, the two ends of the connecting block are laterally grooved to accommodate the supporting rod 2, and the middle of the connecting block is longitudinally grooved, the supporting rod 2 is hinged to the side walls of the lateral grooves, or a connecting shaft rod is disposed between the side walls of the lateral grooves, and the supporting rod is rotatably connected to the connecting shaft rod.

The jacking mechanism comprises a threaded rod 3, a bearing 4, an inner bushing 5 and a pressure head 6, wherein a longitudinal opening is formed in the middle of the connecting block 1, the inner diameter of the longitudinal opening is slightly larger than the outer diameter of the inner bushing 5, and the inner bushing 5 sequentially penetrates through the longitudinal opening and the bearing 4; the bearing 4 is a plane bearing, the bearing 4 is positioned below the middle part of the connecting block 1, and an inner pore channel of the bearing 4 is matched and aligned with the longitudinal screw hole; the lower end of the inner bushing 5 is provided with a bearing limiting part 7, the bearing limiting part 7 comprises bushing nuts, the lower end of the inner bushing 5 is provided with external threads and is in threaded connection with the bushing nuts, and the number of the bushing nuts is two; the inner bushing 5 is provided with internal threads, the threaded rod 3 is connected in the inner bushing 5 in a threaded manner, and the pressing head 6 is connected at the lower end of the threaded rod 3.

The lower surface of the pressure head 6 has a choice of plane and concave cambered surface. Although the top surface of the gland of the end of the spacer is a spherical surface, the lower surface of the pressure head 6 is designed into an inwards concave cambered surface to be matched better, but the surface size of the actually inwards concave cambered surface is difficult to manufacture, so that the finished product surface is difficult to control, the quality is irregular, and the finished product surface is not completely attached to the end surface, and the pressure head 6 may slide or even crack along with the stronger downward pressure applied by the threaded rod 3, and the form of the pressure head 6 covering the gland of the end of the spacer can also enable the pressure head 6 to form an annular nick generated by friction on the gland in the rotating process, so that the appearance and the structural strength are influenced. The design of the lower surface plane of the pressure head 6 is simple to manufacture, the quality of a finished product is relatively guaranteed, the finished product is relatively stable when being tightly pressed, and the problems which are required to be faced by the concave cambered surface do not exist, so that the lower surface of the pressure head 6 can be the concave cambered surface, but the plane is actually designed to be relatively better.

The pressure head 6 is welded and fixed with the lower end of the threaded rod 3. Specifically, all be equipped with the assembly butt joint portion on pressure head 6 and the threaded rod 3, for example set up the butt joint draw-in groove on the pressure head 6, the lower extreme of threaded rod 3 sets up the butt joint, and both butt joints are fixed to it after the assembly is accomplished, and the welded fastening operation is more convenient, and both connect more stably.

The upper end of the inner bushing 5 is fixedly connected with a rotating handle 8, the rotating handle 8 can be a metal rod, such as an iron rod, which is directly welded and fixed, or in the embodiment shown in fig. 1 and 4, a rod sleeve is fixedly connected to the top of the inner bushing 5, and the rod-shaped rotating handle 8 is installed and fixed.

The lower end of the support rod 2 is fixedly connected with a chuck 9. Referring to fig. 1 and 5, the clamping head 9 comprises an assembly connecting section 91 and a clamping section 92, wherein the assembly connecting section 91 is folded with the support rod, the assembly connecting section 91 is fixedly connected with the lower end of the support rod 2, and the clamping section 92 is used for being clamped in a groove at the end of the spacing rod or used for clamping the end surface of the spacing rod by utilizing an included angle opening formed by the folded design of the assembly connecting section 81 and the support rod. The assembling connection section 91 and the clamping section 92 may be integrally formed, or may be two separate components that can be fixedly connected to each other. The collet 9 in this embodiment corresponds to a right-angle block. The end of the spacing rod is an openable ring-shaped member, generally, the outer ring of the spacing rod is provided with a necessary groove, the clamping section 82 is used for being matched with the ring-shaped member, and when the threaded rod 3 and the pressure head 6 press the top of a gland of the ring-shaped member, the clamping section 82 is equivalently lifted upwards and just clamped with the groove. The assembling and connecting section 81 is generally welded to the lower end of the supporting rod 2, and like the threaded rod 3 and the pressure head 6, the assembling and the butt joint can be performed first and then the welding and the fixing are performed.

This scheme operation is simple and easy, and it is more to be suitable for the object, and the centre gripping fastening effect is good and stable, and overall structure intensity is high, and the cost of manufacture is low, actually is suitable for more similar objects more easily, is worth promoting the practicality in this area.

It will be understood by those skilled in the art that the embodiments of the present invention as described above and shown in the drawings are given by way of example only and are not limiting of the present invention. The purpose of the utility model is completely and effectively realized. The functional and structural principles of the present invention have been shown and described in the embodiments without departing from the principles, embodiments of the present invention may have any deformation or modification.
