Description

A kind of printer limit wide sliding block self-locking structure of paper

Technical field

The utility model relates to printer fields, and in particular to a kind of printer limit wide sliding block self-locking structure of paper.

Background technique

Printer will be installed the sliding block for paper tolerance position, mesh to meet the paper of different in width on leading paper bracket The preceding sliding for carrying out sliding block using rack gear and gear on the market, and the damping force provided by damping wheel is come the cunning of lock slider It is dynamic.The more big then locking effect of damping force is better, but hand pushing sliding block will become difficultly when operation sliding block, thus in usage experience It is unsatisfactory, and increasing with access times, damping wheel are also easy to happen damage.

Utility model content

The purpose of this utility model is to provide a kind of printers to limit the wide sliding block self-locking structure of paper, and structure is simple, reliably Property it is high.

In order to achieve the above purposes, the technical solution adopted by the utility model is:

A kind of printer limit wide sliding block self-locking structure of paper, including leading paper rack, being set to the two groups of teeth led below paper rack Item and two groups of teeth meshed gears and the limit for width sliding block being mounted on rack gear, the paper rack of leading is equipped with sliding for limit for width The sliding slot of block sliding, offers up-small and down-big through-hole on the rack gear, the limit for width sliding block is mounted on rack gear by the through-hole On；The top that the limit for width sliding block is located above rack gear is extended with plectrum, which, which is located at, leads in the sliding slot of paper rack；Described group Top fastening station is extended with above piece, the top fastening station is connected to the upper plane for leading paper rack；The limit for width sliding block is located under rack gear The lower part of side is extended with low fastening station, is arranged with spring on the limit for width sliding block between the low fastening station and rack gear, and the two of the spring End is connected to the upper surface of low fastening station and the lower end surface of rack gear respectively.

The spring is pagoda spring.

After adopting the above scheme, the utility model structure is simple and structural reliability is high, is pressed in rack gear by spring It leads below paper rack, the fixation of limit for width sliding block is realized using the frictional force between the two.When the paper width excessively for needing to adjust printing paper When, stir limit for width sliding block, beat occurs for limit for width sliding block unilateral side stress, under the action of plectrum, rack gear with lead rubbing in paper rack It wipes the reduction of power moment or disappears, so that realizing under the cooperation of rack and pinion moves freely limit for width sliding block, to adapt to not Printing paper with width prints between two parties.

Specific embodiment

As depicted in figs. 1 and 2, the utility model discloses a kind of printer limit wide sliding block self-locking structure of paper comprising leads Paper rack 1, be set to lead two groups of teeth item 2 below paper rack, with two groups of teeth meshed gears 3 and be mounted on rack gear Limit for width sliding block 4.

Up-small and down-big through-hole 21 is offered on rack gear 2, above-mentioned limit for width sliding block 4 is mounted in the through-hole 21, so that limit for width Sliding block 4 can towards lead 1 center of paper rack and away from lead paper frame central 1 occur beat.And limit for width sliding block 4 is located at 2 top of rack gear Top is extended with plectrum 41, and plectrum 41, which is located at, leads in the sliding slot 11 of paper rack 1.Top fastening station is then extended in the top of plectrum 41 42, top fastening station 42 is connected in the upper plane for leading paper rack 1.The lower part that limit for width sliding block 4 is located at below rack gear is extended with low fastening station 43, spring 5 is arranged on the limit for width sliding block 4 between low fastening station 43 and rack gear 2, and the both ends of spring 5 are connected to low fastening station 43 respectively Upper surface and rack gear 2 lower end surface, described lead 1 lower section of paper rack so that rack gear 2 is pressed on.Herein, the effect of plectrum 41 There are two, one is used as the locating piece slided in sliding slot 11, the other is pushing away limit for width sliding block 4 or outside inside as plectrum Rack gear 2 is strutted when drawing, makes rack gear 2 and lead to be softened gap between paper rack 1.

As shown in Fig. 3 and Fig. 3 A, when be manually operated limit for width sliding block 4 toward lead Slideslip in paper rack 1 when, limit for width sliding block 4 Top arrow position stress, limit for width sliding block 4 start inside LRO Lateral Runout, and plectrum 41 is made at this time towards the lower edge for leading 1 inside of paper rack The elastic force for supporting tooth punching item of spring 5 is overcome for fulcrum, so that rack gear 2 and leading paper rack 1 and strutting gap, is withstood and is led by spring 5 originally The contact friction force moment of paper rack 1 and rack gear 2 reduces or disappears.Limit for width sliding block 4 is continued to press on, rack gear is relative to gear side To sliding, to drive limit for width sliding block slid inward.

As illustrated in figures 4 and 4, when the thrust of hand is decontroled, since the elastic force of spring 5 makes the inclined limit for width of script sliding Block 4 restores vertical state, this hour rack 2 is led paper rack 1 by the elastic force abutting of spring 5, to generate self-locking frictional force, hindered Hinder limit for width sliding block 4 mobile, for the elastic force for increasing spring 5, the present embodiment uses pagoda spring.

As shown in figs. 5 and 5, when 4 Slideslip outward of limit for width sliding block is manually operated, the top arrow position of limit for width sliding block 4 Stress is set, limit for width sliding block 4 starts the outer LRO Lateral Runout of guide paper rack 1, and plectrum 41 is made at this time towards the lower edge for leading 1 outside of paper rack The elastic force for supporting tooth punching item 2 of spring 5 is overcome for fulcrum, so that rack gear 2 and leading paper rack 1 and strutting gap, is withstood and is led by spring 5 originally The contact friction force moment of paper rack 1 and rack gear 2 reduces or disappears, and sliding block freely slides in and out.

The utility model it is critical that rack gear 2 is pressed in by the utility model by spring 5 leads the lower section of paper rack 1, utilize Frictional force between the two realizes the fixation of limit for width sliding block 4.When needing to adjust when crossing paper width of printing paper, limit for width sliding block 4 is stirred, Beat occurs for the unilateral stress of limit for width sliding block 4, and under the action of plectrum 41, rack gear 2 reduces with the frictional force moment led in paper rack 1 Or disappear, to make limit for width sliding block 4 move freely in rack gear 2 and realization under the cooperation of gear 3, completes printer and cross paper width Adjustment.

The above is only the utility model embodiment, not makees any limit to the technical scope of the utility model System, thus any trickle amendment made by the above technical examples according to the technical essence of the present invention, equivalent variations with repair Decorations, are still within the scope of the technical solutions of the present invention.
