Abstract
The invention discloses a matching structure for a rubber roller of a thermal printer core and an open bearing of a main support. The main support is provided with the open bearing matched with the rubber roller. The size of an opening of the open bearing is smaller than the diameter of the open bearing, and the diameter of the open bearing is matched with the outer diameter of the rubber roller. A plastic elastic arm provided with a sharp point is arranged at the opening of the open bearing. According to the matching structure for the rubber roller of the thermal printer core and the open bearing of the main support, the plastic elastic arm is arranged in the position of the open bearing of the main support, and through the elastic deformation capacity of the plastic elastic arm, matching between the rubber roller and the open bearing of the main support is made simple and firm, and the rubber roller can be disengaged from the open bearing of the main support rapidly and conveniently; and meanwhile, the plastic elastic arm provided with the sharp point, and the main support are of an integrated structure, so that the structure of a whole mechanism is made simple, and the manufacturing cost is effectively reduced.
Description
Technical field
The present invention relates to a kind of thermal printer, particularly relate to a kind of thermal printer cassette rubber roller and main support opening shaft
The fit structure held.
Background technology
The thermal printer cassette of low-cost and easy-to dress paper structure current on market mainly has two kinds:
One is that chute positions mode, as shown in Figure 1.It is fixed that rubber roller i is pressed in the chute in the chute of main support h by printhead sheet j
Bit architecture.This mode shortcoming is to need bigger press-in strength when rubber roller enters print state, and press-in stroke is the most unfavorable
Service life.
Two is that stage clip positions mode as shown in Figure 2.Rubber roller b is pressed in main support a's by printhead sheet d, pressure coil spring c
Stage clip location structure in " u " type groove a1.This structural disadvantages is to need just to prevent rubber roller b from main by pressure coil spring c
Disengage in " u " type groove a1 of frame a.Owing to this coil spring is bending and molding, often can cause elastic force not because material, bending angle are inaccurate etc.
Stable shortcoming, thus common have insufficient pressure cause rubber roller eject or pressure cause the most greatly rubber roller withdrawal force and loading power too
Big is bad；Additionally pressure coil spring and main support use package assembly, the most also have that mechanism is loaded down with trivial details, assembling procedure is complicated
Problem.
Summary of the invention
It is an object of the invention to provide a kind of rubber roll to coordinate with main support simple firm and exit the most just with a body frame
The thermal printer cassette rubber roller of profit and the fit structure of main support opening bearing.
For achieving the above object, the solution of the present invention is:
A kind of thermal printer cassette rubber roller and the fit structure of main support opening bearing, described main support is provided with glue supply roll shaft
The opening bearing coordinated, wherein this bearing is an opening bearing, and the diameter being smaller in size than opening bearing of its opening part, this is straight
Footpath is adaptive with the external diameter of rubber roller, and the opening part of this opening bearing is provided with the plastic resilient of band cusp in the side, direction of printhead sheet
Arm.
The opening part of described opening bearing is smaller in size than bearing diameter.
The plastic resilient arm of described band cusp, cusp is at elastic arm central area elastic arm a length of opening bearing diameter
40%-120% scope.
After using such scheme, the present invention by being provided with the plastic cement bullet of band cusp at the opening part of the opening bearing of main support
Property arm.Utilize the elastic deformability of this plastic resilient arm, make rubber roller the most firm with coordinating of main support, and with body frame
Exit and the most fast facilitate；The plastic resilient arm of this band cusp and main support are the structures of one simultaneously, it is not necessary to separately set wire spring,
Make the simple in construction of whole mechanism, effectively reduce manufacturing cost.

Detailed description of the invention
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
As shown in Fig. 3 to Fig. 6 A, present invention is disclosed a kind of thermal printer cassette rubber roller and main support opening bearing
Fit structure, described main support 1 is provided with the opening bearing 11 that glue supply roll shaft 2 coordinates, to make rubber roll 3 coordinate with printhead sheet 4
Together；
The present invention it is critical only that: described main support is provided with the opening bearing that glue supply roll shaft coordinates, and its middle (center) bearing is one and opens
Mouth bearing 11, its opening size is less than the diameter of opening bearing 11, and this diameter is adaptive with the external diameter of rubber roller 2, this opening bearing
The opening part of 11 is provided with the plastic resilient arm 13 of band cusp 12 in the side, direction of printhead sheet 4, and this cusp is positioned at plastic resilient arm
The elastic arm central area of 13, the 40%-120% scope of this elastic arm a length of opening bearing 11 diameter, this plastic resilient arm 13 exists
Through hole 14 is dodged in the side in printhead sheet 4 direction.
This dodges through hole 14 effect and dodges space when being to make plastic resilient arm 13 have elasticity and have deformation；
This plastic resilient arm 14 opposite side is provided with cusp 12, namely the cusp slot of opening bearing, this cusp slot broad-ruler
Very little less than rubber roller 2 outside dimension.
Coordinate shown in each figure, when rubber roller 2 coordinates with opening bearing 11, rubber roller 2 when by cusp slot, this glue
The plastic resilient arm 13 of roll shaft 2 meeting compressive zone cusp 12, is allowed to deformation and allows rubber roller 2 pass through this cusp slot entrance opening
Bearing 11, simultaneously this plastic resilient arm 13 resilience locked in place rubber roller 2 again keep the original shape of opening bearing 11, in order to axle
Smooth rotation with bearing.Otherwise, when exiting rubber roller 2 from opening bearing 11, reverse above-mentioned action, add certain force value
Get final product the plastic resilient arm 13 of compressive zone cusp 12 so that it is deformation allows rubber roller 2 exit the opening bearing 11 of main support 1.
In sum, the present invention by arranging the plastic resilient arm 13 of band cusp 12 at the opening bearing 11 of main support 1,
And coordinate the side in its printhead sheet 4 direction while arranging and dodging through hole 14, to make the upper side wall of opening bearing 11 form plastic cement
Elastic arm 13, utilizes the elastic deformability of the plastic resilient arm 13 of this opening bearing 11, makes opening of rubber roller 2 and main support 1
Mouth bearing 11 coordinates simple firm, and the most fast facilitates with exiting of body frame 1.The plastic resilient arm 13 of this band cusp 12 simultaneously
It is structure as a whole with main support 1, it is not necessary to separately set wire spring to position bearing relationship.Make the simple in construction of whole mechanism, effectively drop
Low manufacturing cost.
The above, be only presently preferred embodiments of the present invention, not impose any restrictions the technical scope of the present invention,
Therefore the change that claim under this invention and description are done in every case or modification, all should belong to the scope that patent of the present invention contains
Within.
