Detailed Description

For further understanding of the features and technical means of the present invention, as well as the specific objects and functions attained by the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description.

As shown in fig. 1, 2 and 3, the invention discloses an aluminum profile for a portable paper clamping device, which comprises a main body frame 1 and a gravity limiter 2, wherein a containing cavity 4 in the vertical direction is arranged in the main body frame 1, the gravity limiter 2 is placed in the containing cavity 4, the gravity limiter 2 falls to an inlet end of the containing cavity under the action of self gravity, and the size of the inlet end of the containing cavity is smaller than that of the gravity limiter, so that the gravity limiter is blocked at the inlet end of the containing cavity, and paper is tightly pressed by the gravity limiter after being inserted from a position between the gravity limiter and one side surface of the containing cavity. The gravity limiter is freely placed in the containing cavity of the main body frame and falls under the action of self gravity, and the size of the inlet end of the containing cavity is smaller than that of the gravity limiter, so that the gravity limiter can be blocked at the inlet end of the containing cavity and is in contact with the side wall of the containing cavity in a fitting manner.

The accommodating cavity 4 is provided with a first side wall 6 and a second side wall 7, the accommodating cavity 4 is formed between the first side wall 6 and the second side wall 7, and the lower end of the first side wall and the lower end of the second side wall are arranged at intervals to form an inlet end of the accommodating cavity. First lateral wall is vertical wall, and the second lateral wall is the arc wall, and the lower extreme of second lateral wall extends towards first lateral wall arc, and gravity limiter falls behind the entry end that holds the chamber, contacts with first lateral wall and second lateral wall laminating simultaneously, plays the effect that compresses tightly.

The gravity limiter is a round pipe made of an aluminum alloy material, the diameter of the round pipe is usually not larger than 10mm, usually, the main body frame has a certain length, and the round pipe extends into the main body frame from the side face and also has a certain length. For better matching, a plurality of sections of round tubes are used, the sections are matched, and the length of each section can be set to be 50 mm.

The outer surface of the gravity limiter is ground to form a rough surface, so that friction force is increased, and the anti-falling effect can be further realized.

The gravity limiter is made of an aluminum alloy material.

The main body frame is made of an aluminum alloy material, and an anti-oxidation layer is arranged on the surface of the main body frame.

The main body frame 1 is externally sleeved with a sealing cover 5. The sealing cover is made of plastic or aluminum alloy materials, so that the whole body is more attractive and concise.

The paper pressing device only utilizes the self gravity of the gravity limiter to press the paper, is easy to take out and is simpler in structure.

As shown in fig. 3, when no paper is inserted, the gravity limiter is completely blocked at the inlet end of the accommodating cavity and is in contact with the first side wall and the second side wall.

When paper needs to be inserted, as shown in fig. 4, the paper is inserted between the gravity limiter and the first side wall, and the gravity limiter is not fixed, so that the gravity limiter is pushed open by an upward acting force, the gravity limiter is lifted upwards, and the paper can be smoothly inserted.

After the paper inserting sheet is inserted, as shown in fig. 3, the paper is not inserted, namely, the upward acting force is not continuously applied to the paper, at the moment, the gravity limiter does not receive the upward lifting force, the gravity limiter descends again due to self gravity, the inlet end of the accommodating cavity is blocked again, and meanwhile, the paper is compressed, so that the purpose of clamping the paper is achieved.

As shown in fig. 5, when the paper needs to be taken out, the exposed paper is lifted upwards by hand towards the second side wall of the main body frame, the gravity limiter is jacked upwards, a gap is exposed between the gravity limiter and the first side wall, and the paper can be pulled out conveniently and easily.

Although the present invention has been described in detail with reference to the embodiments, it will be apparent to those skilled in the art that modifications, equivalents, improvements, and the like can be made in the technical solutions of the foregoing embodiments or in some of the technical features of the foregoing embodiments, but those modifications, equivalents, improvements, and the like are all within the spirit and principle of the present invention.
