Description

Press printing unit case protective door

Technical field

The utility model relates to a kind of press printing unit case.

Technical background

Press printing unit case is to cover on outside the press printing unit; it had both protected the parts in the printing element not expose; reach the requirement of security protection; can satisfy the requirement of operator's Operation and Maintenance again; leave simultaneously the space after the printing element function is expanded again, keep the integrality of printing machine outward appearance.Existing printing element case adopts full stationary structure mostly, and this kind structure brings inconvenience for the normal maintenance of printing machine, has also limited the printing machine function expansion.The case of employing protection gate-type is also arranged, but the structure of protective door is the locking device of band door lock, for the operator, opening and closing door lock continually, increased service working time, busy because of working sometimes, do not take into consideration to lock, cause protective door to be in free state, form unsafe hidden danger on the contrary.

Summary of the invention

The utility model provides a kind of press printing unit case protective door, this protective door adopts knife-edge structure and strong magnets locking device, closes tightly, and Operation and maintenance are convenient, overcome the defective that protective door is frequently unblanked and shut in the prior art, made printing element case protective door safer.

The utility model is achieved in that a kind of press printing unit case protective door, comprise the parts of forming by steel plate, parts comprise a connection left side, the connector of right casing component, with a left side, right casing component is with hinged left protective door and right protective door, it is characterized in that a left side, right protective door is knife-edge, knife-edge and handle of a knife lateral surface are a left side, right protective door outer surface, knife-edge and handle of a knife medial surface are a left side, right protective door inner surface, a left side, a right protective door inner surface and a left side, right casing component and connector match, on right protective door knife-edge top angle bar is housed, a bit of handle of a knife is left on protective door knife-edge top, a left side, protective door a bit of handle of a knife in a left side matches with right protective door angle bar, on the right protective door strong magnets is housed and inhales mutually, strong magnets is housed on the left protective door inhales mutually with right protective door with the case connector.

In the above-mentioned press printing unit case protective door, the nearly left-hand end in described right protective door knife edge upper end is equipped with strong magnets, this strong magnets is inhaled mutually with the case connector, at the nearly bottom, left side of the right protective door knife back strong magnets being housed inhales mutually with the case connector, the a bit of handle of a knife upper and lower side on protective door knife-edge top, a left side respectively is equipped with strong magnets, and this strong magnets is inhaled mutually with right protective door angle bar.

In the above-mentioned press printing unit case protective door, batten also is equipped with in a bit of handle of a knife outside on described left protective door knife-edge top, and batten is embedded between the left and right protective door.

Operation principle of the present utility model is the left and right sides protective door that adopts steel plate to make; protective door structure is a knife-edge; knife-edge is embedded in left and right sides casing component and connects in the printing element case framework that the connector of left and right sides casing component forms; in that being housed on the protective door, strong magnets is adsorbed on the printing element case framework; left side protective door is adsorbed on the right protective door; left and right sides protective door tightly is adsorbed on the printing element case framework like this, has formed the printing element case, has protected the parts in the printing element.Adopt strong magnets locking protective door structure, opening and closing are easy to operate, and protective door is not easy to open automatically when closing, and make that the protection of printing element case is safer, reliable.Adopting protective door two lateral edges of steel plate structure simultaneously is arc transition, for machine has increased soft and graceful and sense of the times.The open-type structure of printing element case had both helped the manually installation of footpath mechanism for axial adjusting of printing element, also can accommodate the electronic footpath axial adjusting device of larger volume.

Description of drawings

Fig. 1 is a press printing unit case protective door structure schematic diagram, and Fig. 2 is the vertical view of Fig. 1.

Among the figure: 1 left protective door, 2 left casing components, 3 left and right casing component connectors, 4 right protective doors, 5 right casing components, 6 right protective door angle bar, 7 left protective door battens, Final 8's power magnet piece, a bit of handle of a knife on 9 left protective door knife-edge tops, 10 printing wallboards.

Embodiment

Referring to Fig. 1, Fig. 2, a kind of press printing unit case protective door, comprise the parts of forming by steel plate, parts comprise the connector 3 that connects left and right casing component 2,5, with hinged left protective door 1 of left and right sides casing component 2,5 usefulness and right protective door 4, left and right casing component 2,5 usefulness screws are installed on printing wallboard 10 left and right sides, and left and right casing component 2,5 and connector 3 are formed the printing element framework.Press printing unit case protective door sees that from top to bottom referring to Fig. 2, the cross section of left and right protective door 1,4 is knife-edge.Knife-edge and handle of a knife lateral surface are left and right protective door 1,4 outer surfaces, and knife-edge and handle of a knife medial surface are left and right protective door 1,4 inner surfaces, and left and right protective door 1,4 inner surfaces match with left and right casing component 2,5 and connector 3.On right protective door 4 knife-edge tops angle bar 6 is housed, the nearly left-hand end in right protective door 4 knifes edge upper end is equipped with strong magnets 8, and this strong magnets 8 is inhaled mutually with case connector 3, at the nearly bottom, left side of right protective door 4 knife back strong magnets 8 is housed and inhales mutually with case connector 3.A bit of handle of a knife 9 is left on protective door 1 knife-edge top, a left side, and a bit of handle of a knife 9 of left protective door matches with right protective door angle bar 6, at a bit of handle of a knife 9 upper and lower sides of left protective door strong magnets 8 is housed respectively, and this strong magnets 8 is inhaled mutually with right protective door angle bar 6.When protective door is closed, close right protective door 4 earlier, this moment, door was gone up strong magnets 8 and 3 absorption of case connector, by adjusting strong magnets 8 positions to reach the optimal adsorption effect.Close left protective door 1 subsequently, the strong magnets 8 on the left protective door 1 just in time is adsorbed on the angle bar 6 of right protective door.Batten 7 also is equipped with in a bit of handle of a knife 9 outsides on protective door 1 knife-edge top, a left side, and batten 7 is embedded between the left and right protective door 1,4, makes the whole protection door exterior surface smooth, attractive in appearance.Protective door two lateral edges adopt arc transition, from visually having reduced the thick and heavy sense of door, for the rigidity machine has increased soft and graceful and sense of the times, also help operator's safety simultaneously.
