Abstract
The utility model discloses a kind of office automation rubber roll, mainly comprise three arrow aluminum pipes, described three vow aluminum pipe peripheral hardware rubber sleeve, and described three vow that aluminum pipe two ends are axially installed with axle sleeve, and described three vow that aluminum pipe two ends are provided with left mandrel and right mandrel by axle sleeve.The beneficial effects of the utility model: by three, the utility model vows that aluminum pipe replaces the steel pipe in existing office automation rubber roll, significantly alleviate the weight of product, the lightweight for office automated machine provides good approach; Avoid the factor that conventional steel pipe structure mandrel gets rusty easily, improve product quality.
Description
Technical field
The utility model relates to printer technology field, is specifically related to a kind of office automation rubber roll.
Background technology
Along with office automated machine continuous renewal, lightweight, portable, miniaturization become trend, the Heavy Weight of traditional impact printer, it is more painstaking to carry, because traditional marking roll structure adopts the core shaft structure of two types of solid shafting or mandrel and steel-pipe welding structure, its two kinds of structures have the following disadvantages: 1. solid shafting structure is used for the consumption of rubber greatly, and product weight is large, the assembling difficulty of processing is large, there is the hidden danger of quality that rubber skids or ftractures; 2. there are the quality problems that mandrel manufacturing procedure complexity is loaded down with trivial details, mandrel assembling position gets rusty easily in the product of mandrel and steel-pipe welding structure, and owing to adopting the weight of its product of steel pipe also relatively heavier; Also exist and in use print the obvious weak point of noise.
Utility model content
The purpose of this utility model is the defect for above-mentioned prior art, provides one and is convenient to assembling, the simple a kind of office automation rubber roll of with short production cycle and structure.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of office automation rubber roll, mainly comprises three arrow aluminum pipes, and described three vow aluminum pipe peripheral hardware rubber sleeve, and described three vow that aluminum pipe two ends are axially installed with axle sleeve, and described three vow that aluminum pipe two ends are provided with left mandrel and right mandrel by axle sleeve.
As preferred embodiment, described left mandrel centre position is provided with screw thread, a frustum on the right side of described left mandrel.
As preferred embodiment, described right mandrel centre position is provided with screw thread, No. two frustums on the left of described left mandrel.
As preferred embodiment, described axle sleeve inside is provided with screw thread, and described axle sleeve one end is provided with swell hole, described in the macropore diameter that rises be less than sleeve thread stomidium footpath, described axle sleeve is provided with concavo-convex texture in axial direction on the periphery of one end, swell hole.
As preferred embodiment, described axle sleeve and left mandrel and right mandrel are threaded connection.
The beneficial effects of the utility model: by three, the utility model vows that aluminum pipe replaces the steel pipe in existing office automation rubber roll, significantly alleviate the weight of product, the lightweight for office automated machine provides good approach, avoid that conventional steel pipe structure mandrel gets rusty easily factor, improve product quality, described axle sleeve inside is provided with screw thread, described axle sleeve one end is provided with swell hole, the described macropore diameter that rises is less than sleeve thread stomidium footpath, described axle sleeve is provided with concavo-convex texture in axial direction on the periphery of one end, swell hole, described axle sleeve and left mandrel and right mandrel are threaded connection, a described frustum and No. two frustums are arranged in swell hole, degree is goed deep into by left mandrel and right mandrel, a frustum and No. two frustum extruding swell hole internal diameters, the concavo-convex texture on axle sleeve is made only to be pressed in three arrow aluminum pipe inner surfaces, thus prevent axle sleeve and three to vow collecting together between aluminum pipe, assembling is simple, thus simplify existing office automation rubber roll and need left mandrel and the connected mode such as right mandrel and steel-pipe welding, process-cycle shortens greatly.
Accompanying drawing explanation

Fig. 3 is the utility model sectional view.
In figure, description of reference numerals is as follows: 1, left mandrel, and 2, axle sleeve, 3, frustum, 4, rubber sleeve, 5, No. two frustums, 6, three vow aluminum pipes, 7, right mandrel, 21, concavo-convex texture, 22, swell hole.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail:
As shown in Figure 1 to Figure 3, a kind of office automation rubber roll, mainly comprises three arrow aluminum pipes 6, and described three vow aluminum pipe 6 peripheral hardware rubber sleeve 4, described three vow that aluminum pipe 6 two ends are axially installed with axle sleeve 2, and described three vow that aluminum pipe 6 two ends are provided with left mandrel 1 and right mandrel 7 by axle sleeve 2.By three, the utility model vows that aluminum pipe 6 replaces the steel pipe in existing office automation rubber roll, significantly alleviate the weight of product, the lightweight for office automated machine provides good approach; Avoid that conventional steel pipe structure mandrel gets rusty easily factor, improve product quality;
As shown in Figures 1 and 2, described left mandrel 1 centre position is provided with screw thread, a frustum 3 on the right side of described left mandrel 1.Described right mandrel 7 centre position is provided with screw thread, No. two frustums 5 on the left of described left mandrel 1.Described axle sleeve 2 inside is provided with screw thread, and described axle sleeve 2 one end is provided with swell hole 22, and aperture, described swell hole 22 is less than axle sleeve 2 end of thread aperture, and described axle sleeve 2 is provided with concavo-convex texture 21 in axial direction on the periphery of one end, swell hole 22.Described axle sleeve 2 is threaded connection with left mandrel 1 and right mandrel 7, and a described frustum 3 and No. two frustums 5 are arranged in swell hole 22.Described axle sleeve 2 inside is provided with screw thread, described axle sleeve 2 one end is provided with swell hole 22, aperture, described swell hole 22 is less than axle sleeve 2 end of thread aperture, described axle sleeve 2 is provided with concavo-convex texture 21 in axial direction on the periphery of one end, swell hole 22, described axle sleeve 2 is threaded connection with left mandrel 1 and right mandrel 7, a described frustum 3 and No. two frustums 5 are arranged in swell hole 22, degree is goed deep into by left mandrel 1 and right mandrel 7, a frustum 3 and No. two frustums 5 extrude swell hole 22 internal diameter, the concavo-convex texture 21 on axle sleeve 2 is made only to be pressed in three arrow aluminum pipe 6 inner surfaces, thus prevent axle sleeve 2 and three to vow collecting together between aluminum pipe 6, assembling is simple, thus simplify existing office automation rubber roll and need left mandrel 1 and the connected mode such as right mandrel 7 and steel-pipe welding, process-cycle shortens greatly.
