Summary of the invention
The utility model object is to provide a kind of rocking arm hold-down mechanism, and it conveniently manually compresses, and can keep self-locking state after manually compressing.
Based on the problems referred to above, the technical scheme that the utility model provides is:
A kind of rocking arm hold-down mechanism, comprise connecting plate, be hinged on the rocking arm on described connecting plate and connect the cylinder of described one end, also linkage is provided with between described rocking arm and described cylinder, described rocking arm is T font and the pressure arm comprising horizontally set and the connector longitudinally arranged, described connector is hinged on described connecting plate, described linkage comprises the first connecting rod of the hinged described pressure arm in one end, connect the second connecting rod of described first connecting rod and described connecting plate, the hinged described first connecting rod in described second connecting rod one end and the hinged described connecting plate of the other end, described second connecting rod side is provided with connecting portion and is connected with the piston rod of described cylinder.
Further, described second connecting rod opposite side is also provided with the first limited block, and the first limited block described in when manually compressing rocking arm is resisted against on described connecting plate and described first limited block makes described first connecting rod and described second connecting rod be located along the same line.
Further, the other end of described pressure arm is provided with the second limited block in order to connect the parts that need compress.
Compared with prior art, the utility model has the advantages that:
Adopt the technical solution of the utility model, between rocking arm and cylinder, linkage is set, facilitate under cylinder is not ventilated or needed manually operated situation and manual rocking arm to be compressed, and can self-locking state be kept after manually compressing, make hold down gag keep stable.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of a kind of rocking arm hold-down mechanism of the utility model embodiment;
Fig. 2 is the structural representation in another direction of the utility model embodiment;
Wherein: 1, connecting plate 2, rocking arm 21, pressure arm 22, connector 211, second limited block 3, cylinder 4, linkage 41, first connecting rod 42, second connecting rod 421, connecting portion; 422, the first limited block.
Detailed description of the invention
Below in conjunction with specific embodiment, such scheme is described further.Should be understood that these embodiments are not limited to for illustration of the utility model limit scope of the present utility model.The implementation condition adopted in embodiment can do further adjustment according to the condition of concrete producer, and not marked implementation condition is generally the condition in normal experiment.
See Fig. 1-2, for structural representation of the present utility model, a kind of rocking arm hold-down mechanism is provided, it comprises connecting plate 1, be hinged on the cylinder 3 of rocking arm 2 on connecting plate 1 and connecting rocker arm 2 one end, when cylinder 3 is ventilated, cylinder 3 pairs of rocking arm 2 forces make the other end of rocking arm 2 produce the power contrary with cylinder 3 force direction, thus produce thrust, in order to be compressed by rocking arm 2 in cylinder 3 stuffiness or when needing manual, linkage 4 is set between rocking arm 2 and cylinder 3.
Wherein, rocking arm 2 is by being horizontally installed on pressure arm 21 and the connector 22 that longitudinally arranges combines in T font, and wherein connector 22 is hinged on connecting plate 1, and this connector 22 is provided with the groove with connecting plate 1 thickness matching, connecting plate 1 by hinge in groove.
Aforementioned link mechanism 4 comprises the first connecting rod 41 of hinged pressure arm 21 one end, one end and connects the second connecting rod 42 of first connecting rod 41 and connecting plate 1, wherein the hinged first connecting rod 41 in one end of second connecting rod 42 and its other end is articulated and connected plate 1, be provided with a junction 421 in the side of second connecting rod 42 simultaneously, this connecting portion 421 is connected with the piston rod of cylinder 3, and the other end of pressure arm 21 is provided with the second limited block 211 and is connected to the parts that need compress.Like this when cylinder 3 is not ventilated, rocking arm 2 can be compressed by pressing aforementioned link mechanism 4, and rocking arm 2 can be made to be in self-locking state.
In order to optimize the beneficial effects of the utility model further, more stable self-locking state can be kept after manual compression rocking arm 2, the first limited block 422 is also provided with at the opposite side of second connecting rod 42, when manually compressing rocking arm 2, the first limited block 422 to be resisted against on connecting plate 1 and first connecting rod 41 and second connecting rod 42 is on same straight line.
In sum, the utility model compared with prior art has following beneficial effect: adopt the technical solution of the utility model, between rocking arm and cylinder, linkage is set, facilitate under cylinder is not ventilated or needed manually operated situation and manual rocking arm to be compressed, and can self-locking state be kept after manually compressing, make hold down gag keep stable.
Above-mentioned example, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalent transformations of doing according to the utility model Spirit Essence or modification, all should be encompassed within protection domain of the present utility model.
