Abstract
The utility model discloses a self-locking cover of an operating mechanism. A main part of the self-locking cover is a cover plate (1) which is made of steel. The cover plate is provided with a locking slide groove (2). The self-locking cover is arranged in the operating mechanism to realize the flexible control function of a master controller, so in the application of the master controller, the volume is small, the operation feel is light, a transmission part is simple, the on-off operation of a contact is simple, the system control precision is high, the service lifetime is long, and the working performance is stable. Besides, the electrical-mechanical self-locking is realized, and double control operation is realized, thus improving the security.
Description
Technical field:
The utility model relate to a kind of operating mechanism from locking closure.
Background technology:
Master controller is widely used in the crane tool electric control system, belongs to the electric control system core; There are the defectives such as volume is large, operating physical force is large, running part is loaded down with trivial details, and the contact break-make is not clear-cut, and system's control precision is low, and useful life is short, and service behaviour is unstable in the master controller that former domestic industry is used, and mostly is the individual event self-locking, and security performance is low; And the structure of each parts is extremely important in the master controller.
Summary of the invention:
The purpose of this utility model provide a kind of operating mechanism from locking closure;
The utility model is to adopt following technical scheme to realize its goal of the invention: a kind of operating mechanism from locking closure, its main part is the cover plate 1 of steel, which is provided with locking chute 2; 2 designs of locking chute are in the centre of cover plate 1.
Owing to adopted above technology the utility model to realize preferably its goal of the invention, this designs in operating mechanism from locking closure, realized the flexibly function of control of master controller, so that master controller volume in application is little, operating handle is light, running part is simple, the contact break-make is clear-cut, and system's control precision is high, long service life, stable work in work, and can dynamo-electric two self-lockings, the dual control operation has improved fail safe.
Description of drawings:
Accompanying drawing 1 is overall structure schematic diagram of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing summary of the invention is described further:
Embodiment 1:
By accompanying drawing as can be known, a kind of operating mechanism from locking closure, its main part is the cover plate 1 of steel, which is provided with the locking chute 2; 2 designs of locking chute are in the centre of cover plate 1.
Cover plate 1 described in the utility model refers to: steel bowl type cover plate; Which is provided with locking chute 2; Its structure as shown in Figure 1.
Locking chute 2 described in the utility model refers to: design is at the bar-shaped trough of cover plate 1; Its effect is that the outer joystick of tightly locking operating mechanism is finished mechanical self-latching, and slides for the interior joystick of operating mechanism; Its design attitude is shown in mark 2 in the accompanying drawing 1.
Operating mechanism in the denomination of invention described in the utility model " operating mechanism from locking closure " refers to: the patent No. of application was 201220514527.2 on October 09th, 2012, and denomination of invention is the operating mechanism described in " operating mechanism of electromechanical double-control formula master controller " patent; Describedly refer to that from locking closure mark 16 is described from locking closure in the above-mentioned patent.
