Abstract
The utility model provides a hollow square shaft suitable for device is walked to impact printer chain comprises first connector (1), hollow square shaft (2) and (3) three parts of second connector, wherein, first connector (1) and second connector (3) is the injection molding, and hollow square shaft (2) are the metal drawn parts, and first connector (1) and second connector (3) is through the both ends of riveted mode riveting in hollow square shaft (2). The utility model is used for impact printer's chain is compared with traditional solid square shaft in walking the device, and when satisfying its basic transmission function, manufacturing is simple, has greatly lightened weight to the cost is reduced.
Description
Technical field
The utility model relates to stylus printing chain walking apparatus, specifically a kind of hollow square shaft of chain walking apparatus.
Background technique
Prior art chain walking apparatus (chain type form feeder) as shown in Figure 1, be conventional needle printer use chain type form feeder and chain walking apparatus, walk square shaft (13) primarily of chain type form feeder (11) and (12), chain, chain walk guide shaft (14) form.Square shaft (13) walked by chain is wherein metal material solid construction part, and adopt mach mode to process, particularly baroque square shaft, manufacturing procedure is more, and manufacturing efficiency is low, and cost is higher, and heavier-weight.
Model utility content
For overcoming the chain walking apparatus square shaft deficiency structurally of conventional needle printer, the utility model object is, proposes a kind of square shaft of novel chain walking apparatus, lighter in weight, and manufacturing is simple, and with low cost.
The technological scheme that the utility model adopts is: the hollow square shaft being applicable to stylus printing chain walking apparatus, is made up of the first connector (1), hollow square shaft (2) and the second connector (3) three parts; Wherein, first connector (1) and the second connector (3) are mouldings, hollow square shaft (2) is metal draw piece, and the first connector (1) and the second connector (3) are riveted on the two ends of hollow square shaft (2) by the mode of riveted joint.
The beneficial effects of the utility model: three parts link together in the mode of riveted joint.Because 3 parts are all mold members, substantially increase manufacturing efficiency, thus reduce cost.In addition because square shaft is hollow, and wall thickness is very thin, and the solid square shaft that weight ratio is similar is much lower, both can reduce costs, and alleviates again the weight of part.While meeting its basic transmission agency, manufacturing is simple, dramatically reduces weight, and reduces cost.
Accompanying drawing explanation
Fig. 1 is chain walking apparatus pie graph;
Fig. 2 is the pie graph that square shaft walked by chain;
The exploded view of Fig. 3 Fig. 2;
Fig. 4 is the A-A sectional drawing of Fig. 2.
Embodiment
Below by embodiment, structure of the present utility model is further described.
Fig. 3 is the decomposition chart that square shaft walked by chain, and the first connector (1) and the second connector (3) material are POM, for the attachment fitting in chain type form feeder (11) and (12).Hollow square shaft is worked into required length.The shape identical with hollow square shaft cross section inwall is made in connector and one end that hollow square shaft connects, undersized, to facilitate installation, after two connectors and square shaft are seated, by the mode pressed, two connectors and square shaft are fixed together.
By reference to the accompanying drawings mode of execution of the present utility model is explained in detail above, but the utility model is not limited to above-mentioned mode of execution, in the ken that those of ordinary skill in the art possess, can also make a variety of changes under the prerequisite not departing from the utility model aim.
Claims (1)
1. be applicable to the hollow square shaft of stylus printing chain walking apparatus, it is characterized in that being made up of the first connector (1), hollow square shaft (2) and the second connector (3) three parts; Wherein, the first connector (1) and the second connector (3) are mouldings, and hollow square shaft (2) is metal draw piece, and the first connector (1) and the second connector (3) are riveted on the two ends of hollow square shaft (2) by the mode of riveted joint.
