Abstract
The utility model relates to the technical field of equipment maintenance and installation in the mechanical industry, in particular to a hollow flexible connection device, which comprises a hollow cylindrical swing rod, a mount and a cylindrical limit seat. The hollow cylindrical swing rod and the mount are connected via a flexible connecting pipe, the swing rod is provided with a circular raised ring, the swing rod and the mount are respectively inserted into the limit seat, a throat is processed at one end of the limit seat provided with the swing rod, the minimum diameter of the throat is smaller than the outer diameter of the circular raised ring. As the mount, the flexible connecting pipe and the swing rod are all in hollow tubular structure, some wires and cables of equipment can penetrate through centers thereof, damages of cables due to the flexible connection device during rotation and swinging are avoided, and accordingly safety is increased. Further, clearance between the throat and the outer surface of the swing rod is changed along with changes of the diameter of the throat, so that swing range of the swing rod which is connected with the flexible connecting pipe is controlled. In addition, connection reliability between the mount and the flexible connecting pipe and between the swing rod and the flexible connecting pipe is enhanced, thereby preventing the mount and the swing pipe from sliding off.
Description
Technical field
The utility model belongs to mechanical industry overhaul of the equipments and mounting technique field, is specifically related to a kind of hollow flexible connecting device.
Background technique
At some mechanical connection places, often need use some flexible connecting devices, making connected two parts both be joined together can carry-over moment move, and certain relative movement is arranged again.Chang Yong mode of execution was to adopt universal joint to connect or the connection of employing extension spring in the past, but all there is certain defective in these two kinds of linkage structures on some uses: as passing cable from middle inside in the joint, Applicable scope is restricted, or flexible position can't be limited etc.
Summary of the invention
The purpose of this utility model is to provide a kind of hollow flexible connecting device of can be that swinging, that adaptability is good in certain claimed range, being used to connect location or driving torque.
The technical solution of the utility model is as follows:
A kind of hollow flexible connecting device, it comprises the swing arm and the fitting seat of hollow cylindrical, and both connect with flexible steel in flat section tubing, and described swing arm is provided with protruding circular ring; Described connection set also comprises columnar position limit socket, and swing arm and fitting seat stretch into respectively and be installed in the position limit socket, and the end that position limit socket is installed swing arm is processed with reducing, and the minimum diameter of reducing place is less than the external diameter of protruding circular ring.
In above-mentioned hollow flexible connecting device: the cylinder outer wall diameter of described swing arm is less than the minimum diameter of reducing place, so leaves the gap between the cylinder outer wall of swing arm and the reducing.
In above-mentioned hollow flexible connecting device: described swing arm and fitting seat stretch on the cylinder outer wall of part of position limit socket and are provided with screw thread, and flexible steel in flat section tubing is sleeved on outside the screw thread.
In above-mentioned hollow flexible connecting device: described flexible steel in flat section tubing is extension spring or flexible bellow.
The utility model has the advantages that and be: fitting seat, flexible steel in flat section tubing and swing arm adopt hollow tubular structure, make the parts such as some line, cable of equipment to pass from the center, avoid flexible connecting device in rotation or swing process, to damage cable, increased Security; In the flexible steel in flat section tubing outside, put a position limit socket of fixing with the fitting seat connection, a throat structure has been designed in the position limit socket end, by changing reentrant diameter, make the space change of reducing and swing arm outer surface, the hunting range of the swing arm that control is connected with flexible steel in flat section tubing; In swing arm and flexible steel in flat section tubing joint, the annulus of a projection of design, utilize the reducing of position limit socket end to hold this annulus, make swing arm that the swing of certain limit both can have been arranged, prevent from again to be subjected under the situation of certain pulling force at swing arm, the pulling flexible steel in flat section tubing is out of shape vertically, improves the connection precision of hollow flexible connecting device; Fitting seat is designed to thread-like structure with the end that swing arm is connected with flexible steel in flat section tubing, and this structure has increased fitting seat and the reliability that swing arm is connected with flexible steel in flat section tubing, prevents slippage.
Description of drawings
The hollow flexible connecting device overall structure schematic representation that Fig. 1 provides for the utility model;
Fig. 2 is the swing arm schematic representation;
Fig. 3 is the fitting seat schematic representation;
Among the figure: 1. swing arm; 2. protruding circular ring; 3. position limit socket; 4. fitting seat; 5. flexible steel in flat section tubing; 6. position limit socket reducing; 7. screw thread; 8. installation disk.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
As shown in Figure 1, this hollow flexible connecting device is used to connect two parts of mechanical device or instrument, swing arm 1 is connected by flexible steel in flat section tubing 5 with fitting seat 4, position limit socket 3 is the cylinder of hollow, one end of cylinder is processed into reducing 6, at one end swing arm 1 is put into position limit socket 31 of reducing, the other end of position limit socket 3 is put into fitting seat 4.
Swing arm as shown in Figure 2 is a hollow cylinder also, is processed with protruding circular ring 2 on the cylinder, and the external diameter of cylinder barrel is less than the minimum diameter at reducing 6 places, and the external diameter of protruding circular ring 2 is greater than the minimum diameter at reducing 6 places.The part outside that swing arm 1 stretches into position limit socket 3 inside is processed with screw thread 7, at the outside of screw thread 7 suit flexible steel in flat section tubing 5.Thereby by changing reducing 6 place's minimum diameters, make the space change of reducing 6 and swing arm 1 outer surface, the hunting range of the swing arm 1 that control is connected with flexible steel in flat section tubing 5.
Fitting seat as shown in Figure 3 also is the cylinder of hollow, is processed with on the fitting seat 4 disk 8 is installed, and fixedly mounts with position limit socket 3 by disk 8.Also be processed with screw thread 7 on the cylinder outer wall of disk 8 one sides, these end screw thread 7 outer suit flexible steel in flat section tubing 5 extend in the position limit socket 3 then.
As can be seen from Figure 1, an end of flexible steel in flat section tubing 5 is sleeved on outside the screw thread 7 of swing arm 1, and the other end is sleeved on screw thread 7 outsides of fitting seat 4.Described flexible steel in flat section tubing 5 adopts extension spring or flexible bellow.
