The sliding type of pressing cloth pieceTechnical field
The present invention relates to a kind of sliding type structure of pressing cloth piece.
Background technology
The sliding type structure of pressing cloth piece in the prior art, comprise connecting rod, with the pressing cloth piece that described connecting rod arranges mutually slidably, have sliding sleeve on the common described pressing cloth piece, described sliding sleeve is sheathed on the described connecting rod.
Summary of the invention
The technical matters that the present invention will solve provides a kind of sliding type structure of pressing cloth piece.
In order to solve the problems of the technologies described above, a kind of technical scheme that the present invention adopts is: a kind of sliding type of pressing cloth piece, the pressing cloth piece that comprises connecting rod, arranges slidably mutually with described connecting rod, described connecting rod is rounded shaft-like, be provided with rotationally two rollers by the first rotating shaft on the described pressing cloth piece, have the passage that passes for described connecting rod between two described rollers, offer guide rail on two described rollers.
In some embodiments, the length direction of described the first rotating shaft and described connecting rod is perpendicular.
In some embodiments, be provided with lubricating oil between described connecting rod and the described roller.
In some embodiments, two described the first rotating shafts are positioned at the both sides of described connecting rod.
In some embodiments, be provided with the stop gear of the described pressing cloth piece sliding scale of restriction between described connecting rod and the described pressing cloth piece.
Scope of the present invention is not limited to the technical scheme that the particular combinations of above-mentioned technical characterictic forms, and also should contain simultaneously by above-mentioned technical characterictic or its equivalent feature to carry out combination in any and other technical scheme of forming.The technical characterictic that has a similar functions such as disclosed among above-mentioned feature and the application (but being not limited to) is replaced mutually and technical scheme of forming etc.
Because technique scheme is used, the present invention compared with prior art has following advantages: by cooperating between roller and the connecting rod, so that the relative rod slide friction of pressing cloth piece is less, it is more convenient to slide.

The specific embodiment
Shown in accompanyingdrawing 1, accompanyingdrawing 2, a kind of sliding type of pressing cloth piece, thepressing cloth piece 2 that comprises connectingrod 1, arranges slidably mutually with described connectingrod 1, described connectingrod 1 is rounded shaft-like, be provided with rotationally tworollers 4 by the first rotatingshaft 3 on the describedpressing cloth piece 2, have the passage that passes for described connectingrod 1 between two describedrollers 4, offer guide rail on two describedrollers 4.
Described the first rotatingshaft 3 is perpendicular with the length direction of described connectingrod 1.
Be provided with lubricating oil between described connectingrod 1 and the described roller 4.Reduce friction.
Shown in accompanyingdrawing 1, accompanyingdrawing 2, two described the first rotatingshafts 3 are positioned at the both sides of described connecting rod 1.Without diagram, be provided with the stop gear of described pressingcloth piece 2 sliding scales of restriction between described connectingrod 1 and the described pressing cloth piece 2.Described stop gear is not invention main points of the present invention, have the first limiting section and the second limiting section on the connectingrod 1 as described, have the 3rd limiting section on the described pressingcloth piece 2, described the 3rd limiting section is between described the first limiting section and described the second limiting section.
As mentioned above, we are illustrated according to aim of the present invention fully, but the present invention is not limited to above-described embodiment and implementation method.The practitioner of correlative technology field can carry out different variations and enforcement in the scope of technological thought license of the present invention.
