The following is a further explanation of the present invention with reference to the accompanying drawings and embodiments.
Specific embodiment
Referring to figs. 1 to Fig. 3, hand held printer 1 includes shell 11, lid 12, closing piece 2 and elastic component 3, power supply 13, rubber roller
And heat-sensitive sheet, shell 11 are provided with placed cavity 114 and machine core chamber, placed cavity 114 and machine core chamber in relatively independent are arranged, machine core
Chamber is oppositely arranged for placing rubber roller and heat-sensitive sheet, rubber roller and heat-sensitive sheet and carries out clamping paper feed printing with to printing paper.Power supply
13 are arranged in placed cavity 114, are provided with peripheral wall around placed cavity 114, opening is provided on the peripheral wall of 114 side of placed cavity
111。
Referring to fig. 4 to fig. 6, setting is there are two limited block 113 and two positive stop strips 112 at opening 111 for shell 11, and two
Positive stop strip 112 and two limited blocks 113 are respectively positioned on outside placed cavity 114, and intracavitary positioned at machine core, the L-shaped outer projection of limited block 113
It sets, and there is limiting slot, two limited blocks 113 are located between two positive stop strips 112, two limited blocks 113 and two positive stop strips
Sliding slot 110 is constituted between 112, sliding slot 110 is located at opening 111.
Closing piece 2 is provided with lock section 23, operation portion 21 and two locating pieces 22, closing piece 2 and is mounted in sliding slot 110, operation portion
21 are located at opening 111 in the outer part, and closing piece 2 is arranged in sliding slot 110 and 110 can slide along the chute, and lock section 23 is 2 direction of closing piece
Two convex blocks that bayonet 121 stretches out are provided with locating slot 24 between two convex blocks, and convex block is movable in bayonet.
Operation portion 21 and locating piece 22 are located on the opposite side of closing piece 2, i.e., locating piece 22 is located at machine core chamber side, bullet
Property part 3 use torsional spring, torsional spring is by wire coil around constituting, and wire coil is around being formed with volume portion 33 and volume portion 34, volume portion 33 and volume portion 34
Wire coil around contrary, volume portion 33 and volume portion 34 are respectively fitted in a locating piece 22, due to volume portion 33 and volume portion 34
Coiling direction is on the contrary, be located at end 31 and end 32 on sustained height, and the both ends 31,32 of torsional spring abut respectively and limited block
In 113 limiting slot, good balance is provided for torsional spring using mutually level end, shell is connected to by elastic component 3
Between 11 and closing piece 2, so that elastic component 3 applies along 2 moving direction of closing piece to closing piece 2 towards the elastic force of lid.
The lid of lid 12 closes on placed cavity 114, and for the setting of lid 12 there are two bayonet 121, lid 12 is also opposite in bayonet 121
Side be provided with fixture block 122, shell 11 is provided with the card hole cooperated with fixture block 122.When opening lid 12, operation portion 21 is operated
So that unlock far from bayonet 121, is then realized, then under the elastic restoring force of elastic component 3, closing piece return is being covered in lock section 23
It when the lid of body 12 closes, is guided using the inclined-plane of lock section 23, the bayonet and 23 snap fit of lock section of lid 12, lock section 23 also have preset
Elastic force support, then realizes the firm locking of lid.
Therefore the secure lock to lid is realized by the setting of sliding slot, closing piece and elastic component, it is even hand-held to beat
Print machine is dropped, and can be locked to lid using the closing piece for presetting elastic force.Due to the hand-hold printer of this case
Its space will be restricted, therefore be cooperated using torsional spring, in particular by two volume portions of opposite coiling direction, so that turning round
Two ends are more steady evenly to abut with limited block generally within enabling on sustained height for two ends of spring, separately
Also the limit of closing piece is slided by positive stop strip and limited block outside, then realizes the smooth sliding of lock, it is then real using this case
Now to the firm locking of lid.
