The printer door cover device further comprises a flip cover and a flip cover spring, the flip cover spring is connected with the flip cover, and the flip cover is connected with the door cover component through a rotating shaft.

The invention utilizes the lever action of the force applied to one side of the turnover cover and the counterforce applied to the other side of the turnover cover to open the combined piece of the printer door cover component and the turnover cover, and then the combined piece is automatically bounced to the stop point by the torsion spring. Utilize the backstop point that elasticity stopped shelves to carry out reverse backstop, overcome the unstable problem of torsional spring moment of torsion decay back door closure subassembly open mode, for example: the door assembly may be prone to wobble.

The invention has the following technical effects:

the invention utilizes the turnover cover to turn over and the lever action to open the printer door cover, the structure can realize the simple and convenient door cover opening and closing operation, and the part number is less, the reliability is high, thereby saving the cost and improving the satisfaction degree of users. The invention finally realizes the reliable and simple opening of the printer door cover and has lower cost. The invention has wide application prospect in modular design of other industries.

Detailed Description

The following examples of the present invention will be described in detail, but the description should not be construed as limiting the scope of the present invention. All equivalent changes, modifications and the like made within the scope of the present invention shall fall within the protection and coverage of the present invention. In addition, it should be noted that the embodiments and features of the embodiments of the present invention may be combined with each other without conflict.

Examples

According to fig. 2, a printer door cover device is provided, which comprises a printer base assembly (1) and a door cover assembly (4), and is further provided with an elastic stop (2), wherein the printer base assembly (1) is provided with at least one base assembly sliding groove, and the elastic stop (2) can be positioned by the base assembly sliding groove; the device is further provided with a torsion spring (3), the torsion spring (3) comprises a cantilever, the printer base assembly (1) is further provided with at least one torsion spring clamping groove, and the cantilever of the torsion spring can be accommodated in the torsion spring clamping groove.

The printer door cover device further comprises a flip cover (6) and a flip cover spring (5), wherein the flip cover spring (5) is connected with the flip cover, and the flip cover (6) is connected with the door cover component (4) through a rotating shaft.

The installation process of this patent is described below with reference to the accompanying drawings:

the installation steps of the patent are as shown in fig. 3 and fig. 4: the elastic stop (2) is horizontally pushed into the base component (1) and is respectively positioned with the base component sliding grooves (1-21) and the base component sliding grooves (2-22) through the elastic stop rib position (1 (2-1) and the elastic stop rib position (2-2); after the base component is pushed in place, the side walls (1-31) of the sliding chute (2) of the base component and the elastic stop buckle (2-3) are matched with each other to finish fixing;

referring to fig. 5, in the second installation step of the present patent, a torsion spring (3) is sleeved into a torsion spring sleeve column (1-5) of a base component, and a cantilever 1(3-1) and a cantilever 2(3-2) of the torsion spring (3) are respectively clamped into a torsion spring clamping groove 1(1-41) and a torsion spring clamping groove 2(1-42) of the base component;

the third installation step of the patent is as shown in fig. 6, a flip spring (5) is sleeved into a flip spring sleeve column (6-1);

in the fourth and fifth installation steps of the patent, as shown in fig. 7 and 8, respectively, the flip cover (6) is matched with the rotating shaft (4-21) of the door cover component through the rotating shaft hole (6-2), and the flip cover spring (5) is in a compressed state at the moment;

in the sixth installation step of the patent, as shown in fig. 9, the flip cover (6) is pressed downwards, the door cover assembly (4) rotates along with the rotating shaft to move downwards until the compression roller flange (4-11) is clamped and fixed by the printer body clamp spring 1(1-11) and the printer body clamp spring 2(12), and after the installation is completed, the installation is as shown in fig. 10.
