Description

Technical Field

[0001] The invention belongs to the technical field of reinforced printers, and in particular relates to a printer top cover and a shell. Background Art

[0002] Rugged printers play an important role in the military, criminal investigation, industrial production, network communication testing and other fields due to their strong environmental adaptability and high reliability. Existing rugged printers are mainly used for black and white laser printing documents in vehicles or other mobile or non-mobile office locations. The shell structure of traditional rugged printers uses a large cover component, which is difficult to adapt to extreme environments such as small spaces during use and maintenance. Summary of the invention

[0003] The purpose of the present invention is to provide a foldable sliding top cover and shell for reinforcing a printer in order to achieve normal use in a narrow space.

[0004] A technical solution of the present invention is: a foldable sliding top cover for reinforcing a printer, comprising: a foldable top cover section I and a foldable top cover section II connected by hinges.

[0005] A section I top cover strip is installed on each side of the section I folding top cover, and an elastic cylindrical pin I is arranged at the end of each side of the section I folding top cover. The material of the section I top cover strip is steel. The material of the section I folding top cover is aluminum alloy.

[0006] A section II cover strip, two elastic cylindrical pins I and one elastic cylindrical pin II are installed on each side of the section II folding cover; the elastic cylindrical pin II is located at the front end of the side of the section II folding cover. The section II cover strip is made of steel. The section II folding cover is made of aluminum alloy.

[0007] The length of the elastic cylindrical pin II is longer than that of the elastic cylindrical pin I.

[0008] The two pull rings are installed on two pull ring fixing plates, and the pull ring fixing plates are installed on the tail of the folding top cover of section I through a 90° hinge joint.

[0009] Another technical solution of the present invention is: a reinforced printer housing, which includes the foldable sliding top cover as described above, and also includes: a left side panel, a right side panel, a front panel, and a rear panel.

[0010] The left side panel, the right side panel, the front panel, the rear panel and the foldable sliding top cover form a rectangular box structure; a panel baffle is also arranged between the foldable sliding top cover and the front panel.

[0011] The left plate and the right plate have the same structure and are both provided with tracks; four inclined grooves are respectively provided on the tracks from front to back; the four inclined grooves correspond to the elastic cylindrical pin II and three elastic cylindrical pins I on each side of the foldable sliding top cover; when the foldable sliding top cover is closed, the elastic cylindrical pin II is located at the bottom of the inclined groove at the front end of the track, and the three elastic cylindrical pins I are respectively located at the bottom of the three inclined grooves behind the track; when the foldable sliding top cover is pulled, the elastic cylindrical pin II and the three elastic cylindrical pins I slide up from the bottom of the inclined groove to the track to make a linear motion until the foldable sliding top cover is opened.

[0012] On the basis of the above scheme, further, in order to ensure that the foldable sliding top cover slides smoothly during the sliding process (i.e., to ensure that two or more pairs of elastic cylindrical pins are simultaneously located in the straight section of the track to the greatest extent possible), the four inclined grooves between the tracks (20) are designed to be unequally spaced, and the spacing is gradually increased; the track is provided with a distance from the first inclined groove to the second inclined groove from front to back of L1, a distance from the second inclined groove to the third inclined groove of L2, and a distance from the third inclined groove to the fourth inclined groove of L3, and L1+L2 is not equal to L3.

[0013] On the basis of the above scheme, a stop step is further provided at the very end of the track, so that the elastic cylindrical pin II stops at the end position during the pulling and folding of the folding sliding top cover without falling off, thereby avoiding damage to equipment and personnel and playing a limiting role.

[0014] On the basis of the above scheme, further, steps are provided under the tracks of the left and right panels, and conductive rubber sheets are pasted on the steps and 4 electromagnetic coils are installed. A photoelectric sensor is provided on the panel baffle. When the foldable sliding top cover is closed, the pull ring fixing plate is close to the photoelectric sensor, the photoelectric sensor starts to work, and the electromagnetic coil is energized to generate magnetic force, which tightly attracts the top cover pressure strips of section I and section II, so that the foldable top cover of section I and section II press the conductive rubber sheet. When the foldable sliding top cover is opened, the pull ring is pulled, the pull ring fixing plate is away from the photoelectric sensor, the photoelectric sensor is powered off, the electromagnetic coil is turned off, and the electromagnetic force disappears. After the suction force between section I and section II of the foldable top cover and the steps is reduced, the foldable sliding top cover can be easily pulled out, and vice versa, the foldable sliding top cover can be closed.

[0015] On the basis of the above scheme, in order to further meet the electromagnetic shielding requirements on the left, right, front, rear and center sides, the joints of the left panel, right panel, front panel, rear panel, folding sliding top cover and panel baffle are designed to be stepped (which can increase the reflection direction of electromagnetic waves).

[0016] Beneficial effects:

[0017] (1) The top cover of the present invention is designed to be foldable and slideable, which is convenient for pulling out and using in narrow spaces such as military vehicles.

[0018] (2) In the present invention, four unequally spaced inclined grooves are provided on the side panel track and a stop step is provided at the end, which cooperate with the elastic cylindrical pin on the top panel to ensure that the foldable sliding top cover slides smoothly during the sliding process and is not easy to fall off.

[0019] (3) In the present invention, the pull ring position is sensed by a photoelectric sensor. When the foldable sliding top cover is closed, the pull ring fixing plate is close to the photoelectric sensor, the photoelectric sensor starts to work, the electromagnetic coil is energized to generate magnetic force, and the section I top cover pressure strip and the section II top cover pressure strip are tightly attracted, so that the section I folding top cover and the section II folding top cover press the conductive rubber plate. When the foldable sliding top cover is opened, the pull ring is pulled, the pull ring fixing plate is away from the photoelectric sensor, the photoelectric sensor is powered off, the electromagnetic coil is turned off, and the electromagnetic force disappears. After the suction force between the section I folding top cover and the step is reduced, the foldable sliding top cover can be easily pulled out.

[0020] (4) In the present invention, the joints of the left side panel, the right side panel, the front panel, the rear panel, the foldable sliding top cover, and the panel baffle are designed to be stepped, which meets the electromagnetic shielding requirements. BRIEF DESCRIPTION OF THE DRAWINGS
