Abstract
The utility model relates to a transmission connecting rod of an isolating switch. The transmission connecting rod of the isolating switch comprises an operation connecting rod, two ends of the operation connecting rod are in screwed connection with a first connecting tube connector and a second connecting tube connector respectively, a first joint bearing is arranged at the other end of the first connecting tube connector and connected with an operating arm, and a second joint bearing is arranged at the other end of the second connecting tube connector and connected with an operating mechanism. The connecting tube connectors are adopted between the operating mechanism and the operation connecting rod as well as between the operation connecting rod and the operating arm respectively, and the joint bearings are arranged in the connecting tube connectors, so that flexible movement among the operating mechanism, the operation connecting rod and the operating arm is guaranteed, loading capacity and impact resistance are high, and mounting errors can be reduced to the utmost extent.
Description
Technical field
The utility model relates to connecting rod in the mechanical field application, especially relates to a kind of kinematic link of isolating switch.
Background technology
At present, what be used for that the kinematic link of the isolating switch of subway mostly adopts is the rotary type connection monoplane in, even have and micro-drift angle, also be that larger gap is provided, namely the larger installation accuracy of sacrifice reaches, and the relative position of installing is had relatively high expectations, installation accuracy requires also large, but narrow space in the subway tunnel, and need to consider that the maintainer walks about, so need to consider to save as far as possible installing space, and evade interference and the safe distance thereof of other equipment.
Summary of the invention
In order to overcome defects, the utility model provides a kind of kinematic link of isolating switch, has both guaranteed to be connected between connecting rod and the hose coupler reliable, also can make when forming certain angle between connecting rod flexible rotating and absorb to greatest extent alignment error.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of kinematic link of isolating switch, comprise the actuating connecting rod, actuating connecting rod two ends are connected with the first hose coupler and the second hose coupler by screw respectively, the first hose coupler other end is provided with the first oscillating bearing, the second hose coupler other end is provided with the second joint bearing, the first oscillating bearing attended operation arm, second joint bearing attended operation mechanism.
The beneficial effects of the utility model are: between operating mechanism and actuating connecting rod, all adopt hose coupler between actuating connecting rod and motion arm, and be provided with oscillating bearing in the hose coupler, both guaranteed reliability and transmission accuracy between operating mechanism, actuating connecting rod and motion arm; Reduced again desired accuracy class has been installed, farthest absorbed alignment error; Also have larger load-carrying ability and impact resistance.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is A structure for amplifying schematic diagram among Fig. 1;
Fig. 3 is B structure for amplifying schematic diagram among Fig. 1.
Among the figure: 1, the first hose coupler; 1-1, the first oscillating bearing; 2, the second hose coupler; 2-1, second joint bearing; 3, actuating connecting rod; 4, motion arm; 5, operating mechanism.
Embodiment
Below in conjunction with the drawings and the specific embodiments the utility model is described in detail: a kind of kinematic link of isolating switch as shown in Figure 1 to Figure 3, comprise actuating connecting rod 3, actuating connecting rod 3 two ends are connected with the first hose coupler 1 and the second hose coupler 2 by screw respectively, the first hose coupler 1 other end is provided with the first oscillating bearing 1-1, the second hose coupler 2 other ends are provided with second joint bearing 2-1, the first oscillating bearing 1-1 attended operation arm 4, second joint bearing 2-1 attended operation mechanism 5.
Between operating mechanism and actuating connecting rod, all adopt hose coupler between actuating connecting rod and motion arm, and be provided with oscillating bearing in the hose coupler, both guaranteed the flexible motion between operating mechanism, actuating connecting rod and motion arm, also have larger load-carrying ability and impact resistance, can absorb to greatest extent alignment error again simultaneously.
It is emphasized that: above only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does.
