[0017] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1-4The present invention provides a sliding door mechanism for a printer, comprising: a middle shell 1, a first guide rail 2 and a second guide rail 3 symmetrically arranged on the middle shell, a sliding cover 4 slidingly arranged between the first guide rail and the second guide rail, a first door magnet 5 arranged on the middle shell, and a second door magnet 6 arranged on the sliding cover and corresponding to the position of the first door magnet; a cover opening sensor 7 is arranged on the first guide rail or the second guide rail; a cover opening magnet 8 cooperating with the cover opening sensor is installed at the top position of the sliding cover; the cover opening sensor is embedded in a mounting groove 9 installed on the first guide rail or the second guide rail; the cover opening sensor and the cover opening magnet are installed on the same side and opposite to each other. The cover opening magnet can be detected when the sliding cover is closed, and cannot be detected when the sliding cover is opened. After the cover opening sensor disengages from the cover magnet, it detects the door opening and sends a signal to the connected printer to execute related tasks. There are holes for installing magnets on the front and lower side of the sliding cover. The second door suction magnet is installed in the door suction installation hole 10 on the front of the sliding cover, and the cover opening magnet is installed in the cover opening installation hole 11 on the lower side. The first door suction magnet is installed on the middle shell and can be pasted or embedded in the hole groove. Two sets of door suction magnets are installed on the middle shell and the sliding cover respectively, and have a good feel whether opening or closing the cover.

[0019] Specifically, rebound mechanisms are respectively provided between the first guide rail, the second guide rail and the sliding cover to assist the upward opening and downward closing actions of the sliding cover, wherein the rebound mechanism is a torsion spring 12, one end of which is provided on the first guide rail or the second guide rail, and the other end is provided on the sliding cover. The dual power of the door magnet and the torsion spring is superimposed to form a semi-automatic door opening mechanism, so that the sliding door can realize semi-automatic function.

[0020] Specifically, a first mounting point 13 of a torsion spring is provided on the first guide rail and the second guide rail, and two sets of second mounting points 14 of a torsion spring are provided on the sliding cover. One end of the torsion spring is wound around the first mounting point, and the other end is wound around the second mounting point. When the hand-pushed sliding cover moves to the second mounting point and is flush with the first mounting point, the torsion spring is in the maximum compression state and has the maximum resilience. When the sliding cover needs to be opened, the hand-pushed sliding cover moves upward to the middle position (that is, the position where the first mounting point is flush with the second mounting point), and a slight upward force is applied, and the two sets of The torsion springs are guided to push the sliding cover upward together, and the sliding cover can slide to the fully open position by itself. Opening the cover has a certain feel, and at the same time, after the cover opening sensor disengages from the cover opening magnet, it detects the door opening and tells the printer to perform the relevant task; when the sliding cover needs to be closed, pull the sliding cover back to the middle position with your hand and apply a little downward force. The two sets of torsion springs push the sliding cover downward together, and the sliding cover closes. When the first door magnet and the second door magnet are very close, the attraction of the two sets of door magnets makes the sliding cover completely closed. At the same time, the cover opening sensor detects the cover opening magnet, and the printer performs the corresponding task.

[0021] Specifically, a guide rail groove 15 is provided on the inner side of the first guide rail and the second guide rail, and sliding columns 16 that can slide back and forth in the guide rail groove are provided on both sides of the sliding cover. The guide rail groove consists of a downward inclined groove and a flat groove from the outside to the inside. The guide rail groove is first inclined downward at 45 degrees and then becomes a flat groove. This is more ergonomic and uses pushing force to open the door.

[0022] The beneficial effects of the utility model are:

[0023] (1) Through the cooperation of two sets of door magnets and torsion springs, the sliding door can achieve semi-automatic function, which has a strong sense of technology;

[0024] (2) Through the cover opening sensor, the open and close sliding cover is linked with the printer to control the relevant actions of the printer;

[0025] (3) The guide rail’s structure of first an oblique groove and then a flat groove perfectly fits ergonomics, making it very easy to open and close the cover.

[0026] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
