Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

The invention discloses a device for simultaneously opening and closing a plurality of Ep pipe covers, which comprises a strip-shaped press cover plate 1 and a strip-shaped prying plate 2 which are transversely arranged in parallel, wherein the press cover plate 1 is a cuboid with the size of 60mm multiplied by 15mm multiplied by 5mm, the cross section of the prying plate 2 is trapezoidal, the upper surface and the lower surface of the prying plate 2 are non-parallel inclined surfaces, the prying plate 2 is positioned below the middle part of the press cover plate 1, and the press cover plate 1 and the prying plate 2 are jointly connected with a handheld piece 4.

The hand-held piece 4 is 50mm 10 mm's aluminium alloy square bar, and hand-held piece 4 sets up with gland plate 1, sled board 2 is perpendicular, and 4 bottoms of hand-held piece are the cambered surface.

The pry plate 2 is connected to the handpiece 4 by a support arm 3. One end of the supporting arm 3 is fixedly connected with the lower bottom surface of the prying plate 2, the other end of the supporting arm 3 is fixedly connected with the hand piece 4, and an included angle is formed between the supporting arm 3 and the hand piece 4 and ranges from 30 degrees to 45 degrees.

The gland plate 1 and the prying plate 2 are both aluminum alloy plates, the supporting arm 3 is an aluminum alloy supporting arm, and the hand piece 4 is an aluminum alloy square bar. The cover pressing plate 1, the prying plate 2, the supporting arm 3 and the hand piece 4 are made of aluminum alloy materials because the aluminum alloy is easy to weld and process and is firmly welded, so that the phenomena of scratching and welding are avoided, and the service life is long; the aluminum alloy is not easy to rust and can resist high temperature and high pressureAcid and alkali resistance, and is not easy to corrode; the aluminum alloy has small density, generally 2.5 multiplied by 10³～2.88×10³kg/m³And has low cost and good quality.

The surfaces of the gland plate 1, the prying plate 2 and the hand piece 4 are provided with silicon rubber layers. The silicon rubber layer is used as a protective layer because the silicon rubber is tasteless and nontoxic, resists high temperature and high pressure, is oxygen-resistant and ageing-resistant, and Si-O-Si bonds in the silicon rubber are very stable to oxygen, ozone, ultraviolet rays and the like.

The working process of the device for simultaneously opening and closing the multiple Ep pipe covers is as follows:

when the cover is opened, as shown in fig. 3, the lower surface of the gland plate 1 is abutted against the plane of the Ep tube cover 6, then the hand-held piece 4 is held by hand, the higher edge of the upper surface of the prying plate 2 is abutted against the opening 5 of the Ep tube cover 6, and the Ep tube cover 6 can be opened by exerting force in the direction of an arrow.

When the Ep pipe is arranged on the Ep pipe frame, the Ep pipe cover 6 can be smoothly opened through the Ep pipe auxiliary cover opening and closing device of the invention due to the binding effect of the Ep pipe frame. And when 4-6 Ep tubes are arranged in an orderly manner on the Ep tube frame, the Ep tubes can be opened at the same time at one time.

When the cover is closed, as shown in fig. 4, the lower surface of the gland plate 1 is abutted against the plane of the Ep tube cover 6, the hand-held piece 4 is held by a hand, the higher edge of the upper surface of the prying plate 2 is abutted against the opening 5 of the Ep tube cover 6, and the Ep tube cover 6 can be closed by applying force in the opposite direction during opening.

When the Ep pipe is arranged on the Ep pipe frame, the Ep pipe cover 6 can be smoothly closed by the Ep pipe auxiliary cover opening and closing device. Similarly, when 4-6 Ep tubes are arranged in an orderly fashion on an Ep tube holder, they can be closed at the same time at one time.
