Abstract
The utility model discloses a printer carriage unit horizontal left-right movement guide mechanism, which comprises a word frame, wherein a guide shaft is movably run through the lower portion of a word frame, a guide rail which is parallel to the guide shaft is arranged above the guide shaft, a locking clamp and a guide wheel which are respectively arranged on the front and the rear sides of the guide rail are arranged on the upper portion of the word frame, the middle portion of the locking clamp is hinged with the word frame, a spring which enables the locking clamp to rotate around a hinged position and press the guide wheel is arranged between the lower portion of the locking clamp and the work frame, and the locking clamp which is hinged on the word frame in the middle portion applies a force which enables the lower portion of the locking clamp to depart away form the word frame to the lower portion of the locking clamp through the spring which is arranged between the lower portion of the locking clamp and the word frame. The upper portion of the locking clamp can rotate around the hinged position and press toward the guide wheel according to lever principle, thereby enabling the guide rail which is arranged between the guide wheel and the locking clamp to be clamped, guaranteeing a carriage unit to be clung to the guide rail during the horizontal left-right movement process, and contributing to improve printing quality of a printer.
Description
Technical field
The utility model relates to a kind of printer carriage, particularly the guiding mechanism that moves left and right of a kind of printer carriage level.
Background technology
At present, domestic most printer is all to move back and forth along about the guide rail level under the driving of drive unit by the word car, thereby driving printhead constantly moves back and forth and prints about level on printing paper, when the word car is made level left and right shift reciprocately and is moved along guide rail, easily because of the impact of vibrations or external force, can not be close to guide rail and move, make the word car jumping phenomena occur, depart from guide rail, thereby caused the printing effect of printer undesirable.
The utility model content
In order to address the above problem, it is a kind of simple in structure that the purpose of this utility model is to provide, and prevents that printer carriage departs from guide rail in about level moves back and forth process word car level from moving left and right guiding mechanism.
The utility model for the technical scheme that solves its technical problem and adopt is:
the guiding mechanism that a kind of printer carriage level moves left and right, comprise the word vehicle frame, the bottom activity of word vehicle frame is coated with the axis of guide, the top of the axis of guide is provided with the guide rail that parallels with it, described word vehicle frame top is provided with locking clamp and the directive wheel that lays respectively at side before and after guide rail, the locking clamp middle part is hinged with the word vehicle frame, be provided with between locking clamp bottom and word vehicle frame and can make locking clamp rotate and press to the spring of directive wheel around the hinged place, above-mentioned middle part is hinged on locking clamp on the word vehicle frame and by the spring between its underpart and word vehicle frame, its underpart is applied one and make the locking clamp bottom away from the power of word vehicle frame, according to lever principle, directive wheel be rotated and be pressed in locking clamp top can around the hinged place, thereby making directive wheel and locking clamp will be positioned at their guide rails between the two clamps, assurance word car moves left and right in level is close to guide rail in process, prevent the impact because of vibrations or external force, jumping phenomena appears in the word car, thereby guaranteed the printing effect of printer.
further, described locking clamp upper and lower is respectively arranged with and the projection of guide rail sliding-contact and the cylinder of being convenient to the spring location and installing, the left and right sides, locking clamp middle part also is provided with two fulcrums that are hinged with the word vehicle frame, fulcrum and word vehicle frame by both sides, locking clamp middle part are hinged, the hinged dynamic balance of the left and right sides that is subject to when making the locking clamp rotation, prevent that locking clamp from coming off, projection can make the frictional force between locking clamp and guide rail reduce simultaneously, cylinder can be rabbeted at spring inner in addition, facilitate spring fitting to locate, when preventing that locking clamp top from pressing to directive wheel, the application point of spring-force driven dual on the locking clamp bottom changes, guarantee the rotating torque kept stable that locking clamp is subject to, be not easy to change.
Further, the left and right sides, described word vehicle frame bottom is provided with two dead eyes that are socketed on the axis of guide, two above-mentioned dead eyes can make the stressed uniform balance more of word vehicle frame, prevent that the word vehicle frame from doing the phenomenon that twists when about level moves back and forth along the axis of guide.
the beneficial effects of the utility model are: will be hingedly mounted on the structure on word vehicle frame top in the middle part of locking clamp because the utility model adopts, and arrange between locking clamp bottom and word vehicle frame and can make the locking clamp bottom away from the spring of word vehicle frame, by spring, the locking clamp bottom being applied one makes it away from the active force of word vehicle frame, according to lever principle, locking clamp top is subject to an active force that makes it press to directive wheel, directive wheel is rotated and presses on locking clamp top around the hinged place, directive wheel and locking clamp top will be positioned at their guide rails between the two and clamp, thereby make the word car be close to guide rail, jumping phenomena occurs when preventing the shift reciprocately motion of word car level left and right, guaranteed the printing effect of printer, simultaneously, the locking clamp bottom is provided with the cylinder of being convenient to the spring location and installing, and can prevent that spring action from changing at the application point of locking clamp bottom, thereby the opplied moment kept stable that makes locking clamp be subject to is not easy to change, the utility model is simple in structure in addition, and is easy for installation, helps to reduce labour intensity and reduces production costs.
