The specific embodiment

In order to make those skilled in the art person understand the utility model scheme better, the utility model is described in further detail below in conjunction with drawings and embodiments.

Referring to Fig. 2, Fig. 3, Fig. 4, Fig. 2 is the stereogram of the printer that provides of the utility model, and Fig. 3, Fig. 4 are respectively the unlatching of printer provided by the utility model and locking explosive view and the installation diagrams with associated mechanisms.Printer comprises upper shell 1, middle shell 2 and lower house 3.Upper shell 1 comprises first bracing frame 10, and described first bracing frame 10 is fixedly set in upper shell 1 inside.Be provided with groove 20 with opener 40 corresponding positions on described printer middle shell 2, when user's open printing machine upper shell 1, the user can insert groove 20 with its thumb, to carry out open operation.Referring to Fig. 7, described middle shell (2) comprises second bracing frame (50), and described second bracing frame (50) is fixedly set in the inside of middle shell (2).

As shown in Figure 4, the printer that provides of the utility model is opened and locking comprises with associated mechanisms: opener 40, retaining mechanism 41, rotating shaft 42, extension spring 43.

Referring to Fig. 5, Fig. 7, opener 40 comprises handle 40a in the lump, the first fixing hole 40b, depression bar 40c; Described opener 40 is arranged at the inner surface of printer upper shell, and is positioned at directly over the groove 20, and when the user needed open printing machine upper shell 1, the user inserted groove 20 and can be easily the handle 40a of opener 40 be carried out pressing operation by pointing.

Be understandable that the groove 20 of above-mentioned middle shell 2 gets final product with these opener 40 corresponding settings, be not limited to be positioned at opener 40 under.

Be understandable that the shape of described groove 20 can be pointed the arbitrary shape of insertion for the convenience of the user.

Referring to Fig. 6, retaining mechanism 41 comprises limit shaft 41a in the lump, latch hook 41b, the extension spring first installing hole 41c, the rotating shaft first installing hole 41d.

First bracing frame 10 comprises connecting rod installation shaft 10a, stopper slot 10b, the rotating shaft second installing hole 10c, the extension spring second installing hole 10d, bracing frame installing hole 10e.

Below in conjunction with Fig. 3, Fig. 4, Fig. 7 illustrate open and each part of retaining mechanism between annexation.

The rotating shaft second installing hole 10c, the rotating shaft first installing hole 41d are passed in rotating shaft 42 successively, and retaining mechanism 41 is rotatably installed on first bracing frame 10.The limit shaft 41a of retaining mechanism 41 passes the stopper slot 10b that is arranged on first bracing frame 10; Described stopper slot 10b is curved, and when external force drove limit shaft 41a, limit shaft 41a moved in stopper slot 10b, and limit shaft 41a will drive

retaining mechanism

41 and 42 rotate around the shaft.The first fixing hole 40b of opener 40 cooperates with the connecting rod installation shaft 10a of first bracing frame 10, is used to make opener 40 to be rotatably mounted in first bracing frame 10.Depression bar 40c on the opener 40 is overlapped on the limit shaft 41a of retaining mechanism 41, when there not being external force to do the time spent, and the two contact, do not have and interact, when external force acted on depression bar 40c, depression bar 40c pushed limit shaft 41a downwards, made limit shaft 41a

drive retaining mechanism

41 and 42 rotated around the shaft.

Extension spring 43 1 ends are fixed in the extension spring first installing hole 41c on the retaining mechanism 41, and the other end is fixed in the extension spring second installing hole 10d on first bracing frame 10.Under extension spring 43 pulling force effects, because the opening of stopper slot 10b upwards and curved, retaining mechanism 41 has around the shaft 42 trend that turn clockwise.First bracing frame 10 is hinged by bracing frame installing hole 10e and middle shell 2, so that first bracing frame 10 can be rotated around pin joint 30, here, pin joint 30 matches with bracing frame installing hole 10e, and first bracing frame 10 is rotatably installed on second bracing frame 50 of middle shell 2 (referring to Fig. 7).

Fig. 8 be the printer that provides of the utility model when upper shell is locked, the stereogram that its retaining mechanism 4 cooperates with middle shell, for clear display, this view only keeps correlated parts at this.As shown in Figure 8, step 21 is set on middle shell 2, step 21 and latch hook 41b be interlocking mutually.When printer upper shell 1 needed locking, the latch hook 41b of retaining mechanism 41 tightened step 21 under the pulling force effect of extension spring 43, thereby makes printer upper shell 1 tight closure.

Need to prove that also lock shaft can be set on middle shell, the latch hook 41b of retaining mechanism 41 is the clamping lock mandrel under the pulling force effect of extension spring 43, thereby make printer upper shell 1 tight closure.

Certainly, the utility model is not limited to the interlocking mutually by lock shaft or step 21 and latch hook 41b, can also be other can with the latch hook 41b locking member of interlocking mutually.

The opening process of printer upper shell 1 is described in conjunction with Fig. 2, Fig. 7 in the lump.

At first, the user inserts groove 20 with its thumb, uses power upwards to push handle 40a, and opener 40 clockwise rotates around connecting rod installation shaft 10a under external force, thereby makes depression bar 40c push limit shaft 41a downwards.Limit shaft 41a is under the downward extruding force of depression bar 40c, drive retaining mechanism 41 along stopper slot 10b, the elastic force that makes retaining mechanism 41 overcome extension spring 43 42 rotates counterclockwise around the shaft, so after retaining mechanism 41 has rotated certain angle, latch hook 41 b will break away from step 21, continue to use power upwards to push under the situation of handle 40a the user, upper shell 1 will be lifted and turn clockwise around pin joint 30, until opening.

The foregoing description is a preferred embodiment of the present utility model, the printer that the utility model provides is arranged at the handle 40a of open printing machine the inside of printer upper shell 1, thereby can allow the outer surface of upper shell not have the slit, make printer have the waterproof and dustproof function, make things convenient for the user to the laying of printer, improved the ability that printer conforms greatly.Simultaneously, because opener is arranged on the inside of upper shell 1, fuse with upper shell, the user only needs one hand is inserted the groove 20 of printer middle shell 2, and the handle 40a of the press-started mechanism 40 that makes progress, can realize the unlatching of printer upper shell 1, therefore, simple to operation, improved the unlatching efficient of printer greatly.

The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
