Abstract

The utility model belongs to a strut the structure, especially relate to a rubber band strut support assembly. This assembly is including strutting the frame, it sets up respectively to strut frame symmetry both ends and struts the cylinder, the utility model discloses a setting is strutting two of frame both sides and struts the cylinder and promote respectively rather than the board that struts that offsets to drive the folding arm that struts rather than being connected and long arm that struts through strutting the board, strut the rubber band by the rubber band post again and strut the rubber band, and automatic return under the effort through return spring, compare with current rubber band strutting arrangement, the structure is simpler, it is more convenient to use, cylinder quantity obviously reduces, not only for the producer saved manufacturing cost, the possibility that the mechanism takes place to damage has also been reduced simultaneously, it is also more convenient to maintain.

Description

Strutting bracket assembly of rubber band

Technical Field

The utility model belongs to a strut the structure, especially relate to a rubber band strut support assembly.

Background

With the continuous improvement of the life of people, the use of plastic bags is wider and wider, so the usage amount is increased gradually, when the plastic bags are sold, the plastic bags are not sold by taking each plastic bag as a sales unit, but are bundled into bundles for sale, and the current bundling mode of the plastic bags is mostly in the form that a rubber band is sleeved on the plastic bag and is generally finished by a rubber band opening mechanism or manually. Rubber band on the market struts mechanism, generally is equipped with four cylinders, drives respectively by four cylinders and struts the arm and strut the rubber band, because the cylinder expense is higher, leads to the whole cost of mechanism to be on the high side, has improved producer's operating cost, on the other hand, what of cylinder quantity has influenced the degree of difficulty that the mechanism was made and was maintained indirectly, rubber band on the market struts mechanism, because cylinder quantity is more, if the condition of taking place the damage, it will be very inconvenient to maintain.

Disclosure of Invention

In order to solve the technical problem, the utility model provides a rubber band strut support assembly.

The utility model discloses a realize above-mentioned purpose and the technical scheme who takes does:

the utility model provides a rubber band strut support assembly, this assembly is including strutting the frame, the frame symmetry both ends that strut set up respectively and strut the cylinder, the output axle head both sides that strut the cylinder set up respectively and strut the board, strut board one side and the output axle head that struts the cylinder offset, the one end and the folding arm of strutting of board link to each other, folding strutting the articulated setting of arm and strutting the frame or strutting the cylinder, folding strutting and setting up long strutting arm on the arm, the end of long strutting arm set up the rubber band and strut the post.

As a further improvement, the long stretching arms are of L-shaped structures, and the output shaft ends of the stretching cylinders are arranged in an up-and-down overlapping mode corresponding to the long stretching arms on the two sides.

As a further improvement, the tail end of the folding opening arm is provided with a return elastic sheet, and the return elastic sheet is abutted against the tail end of the folding opening arm.

As a further improvement, the tail end of the folding and unfolding arm is provided with a roller which is propped against the return elastic sheet.

As a further improvement, the output shaft end of the expanding cylinder is provided with a straight groove, and the expanding plate is partially arranged in the straight groove.

The utility model discloses a setting is strutting the cylinder and promoting respectively rather than the expansion plate that offsets in two of strutting the frame both sides to drive folding expansion arm and the long expansion arm rather than being connected through the expansion plate, it struts the rubber band by the rubber band opening post again, and self return under the effort through return spring, compare with current rubber band opening device, the structure is simpler, it is more convenient to use, cylinder quantity obviously reduces, not only save manufacturing cost for the producer, the while has also reduced the possibility that the mechanism takes place to damage, it is also more convenient to maintain.
