Abstract
The utility model relates to a guide mechanism for the transverse reciprocating shift of a carriage unit of a printing machine, which comprises a transverse guide rod of the carriage unit and a printing head sleeved on the transverse guide rod through a bearing hole of an L-shaped bracket and is characterized in that an upper cross beam parallel to the transverse guide rod is also arranged above the transverse guide rod; the printing head is connected to the lower end of the L-shaped bracket; the upper end of the L-shaped bracket is matched with the upper cross beam by a pair of rolling bearings located at the front side and the rear side of the upper cross beam; and a bearing hole matched with the transverse guide rod is arranged at the middle part of the L-shaped bracket. The mechanism has the advantages of simple structure and good printing effect, and the more stable operation of the carriage unit can be ensured during the printing process.
Description
Technical field
The utility model relates to the laterally reciprocal displacement guiding mechanism of a kind of printer word car.
Background technology
The word mechanism of car of impact printer is used to load printhead, and makes traverse motion at the driving lower edge guide rail of motor and synchronous band, to realize printing function.When the word car when guide rail moves back and forth, normal because of the sliding and running instability between word car and the guide rail, influence print job.
Summary of the invention
The purpose of this utility model is to provide a kind of printer word car laterally reciprocal displacement guiding mechanism, and this mechanism is not only simple in structure, and it is more steady to guarantee that the word car moves in print procedure, and printing effect is good.
The technical solution of the utility model is: the laterally reciprocal displacement guiding mechanism of a kind of printer word car, comprise the horizontal guide rod of word car and be sheathed on printhead on the horizontal guide rod through the dead eye of L type support, it is characterized in that: described horizontal guide rod top also is provided with the entablature that parallels with it, printhead is connected the lower end of L type support, the upper end of L type support matches with entablature through a pair of rolling bearing that is positioned at entablature front and back side, and the middle part of L type support is provided with the dead eye that cooperates with horizontal guide rod.
The rolling bearing of described entablature rear side is connected on the resiliency supported sheet, and the upper end of L type support is provided with a block that is positioned at the entablature rear side.
The utility model is simple in structure, utilizes former and later two rollers that the word car is clipped on the entablature track, makes the motion when horizontal shift reciprocately of word car more steady; Crossbeam rear side ball supports by the changeability flat spring, has self-regulating function, remains the word car and contacts with the good of crossbeam track; When the user when fastening the printer protecgulum, push the word car through regular meeting, the spring failure that the stopping means on the word car causes in the time of can effectively preventing to press down the word car.

Fig. 3 is the A-A cutaway view of Fig. 2.
Fig. 4 is the structural representation that rolling bearing cooperates with entablature.
The specific embodiment
The laterally reciprocal displacement guiding mechanism of a kind of printer word car, comprise the horizontal guide rod 1 of word car and be sheathed on printhead 4 on the horizontal guide rod through the dead eye 3 of L type support 2, it is characterized in that: described horizontal guide rod top also is provided with the entablature 5 that parallels with it, printhead is connected the lower end of L type support, the upper end of L type support matches with entablature through a pair of rolling bearing that is positioned at side before and after the entablature 6,7, and the middle part of L type support is provided with the dead eye that cooperates with horizontal guide rod.
The rolling bearing of described entablature rear side is connected on the resiliency supported sheet 8, the upper end of L type support is provided with a block 9 that is positioned at the entablature rear side, the resiliency supported sheet has automatic regulatory function, remain the word car and contact, guarantee that print procedure word car operates steadily all the time with the good of crossbeam track; When the user when fastening the printer protecgulum, if firmly push the word car, block can play position-limiting action, can prevent the inefficacy of spring.
The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
Claims (2)
