Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

In which like parts are designated by like reference numerals. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "bottom" and "top," "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

Embodiments of the present invention are further described with reference to fig. 1 to 3.

The embodiment specifically includes: support body 1 and roller 2, roller 2 and support body 1 rotate to be connected. The bearing is installed on the frame body 1, the two ends of the roll shaft 2 are connected with the bearing of the frame body 1, and the roll shaft 2 rotates relative to the frame body 1.

The roller shaft 2 is provided with an adjusting unit which comprises a first stopper 31 and a second stopper 32, and an active area for moving the sheet (film) is formed between the first stopper 31 and the second stopper 32. The first stop 31 and the second stop 32 are detachably connected with the roller shaft 2.

The first stopper 31 and the second stopper 32 are made of rubber, and have a cavity 30 therein, and have a movable opening 300 formed at one side thereof to communicate with the cavity 30.

The first stopper 31 and the second stopper 32 are elastically deformed by abutting against the roller shaft 2 through the movable opening 300, so that the first stopper 31 and the second stopper 32 are sleeved on the outer circumferential wall of the roller shaft 2.

An annular protrusion 3b is formed on the inner wall of the junction of the movable opening 300 and the cavity 30.

The movable opening 300 has a recess 3a on the outer wall thereof, and the recess 3a has an arc-shaped cross section.

When the first stopper 31 and the second stopper 32 are connected with the roller shaft 2, the movable opening 300 is inserted in a direction opposite to the roller shaft 2, and the movable opening 300 has elasticity and can deform when being extruded with the roller shaft 2, so that the opening is expanded outwards and is continuously extruded towards the roller shaft 2, and the hollow cavities 30 of the first stopper 31 and the second stopper 32 are sleeved on the roller shaft 2 to finish installation; when the size of the active area needs to be adjusted, the first stop block 31 and the second stop block 32 are pulled out from the roller shaft 2.

In order to improve the stability of the installation of the first stopper 31 and the second stopper 32 on the roller shaft 2, the two magnetic blocks 3c are embedded after the opening is formed on the inner wall of the movable opening 300. The two magnetic blocks attract each other, so that the movable opening 300 is kept stable.

Since the movable opening 300 is deformed and is not broken due to its excessive deformation, the annular protrusion 3b and the recess 3a are provided on the inner wall and the outer wall. The recess 3a enables the movable opening 300 to have a deformation space large enough to be opened so as to be easily fitted into the roller shaft 2;

the annular projection 3b serves the purpose of pressing the roller shaft 2, and improves the stability of installation when it is pressed with the roller shaft 2.

Through holes (301, 302) are arranged on the first stop block 31 and the second stop block 32. Because of the thickness relation of the film, the through holes are arranged in two groups corresponding to the distance between the through holes and the central hole.

Run through on the through-hole and have axostylus axostyle 4, the aperture of through-hole is greater than the diameter of axostylus axostyle 4, 4 one end of axostylus axostyle and 1 swing joint of support body, swing joint has roller body 5 on the other end.

The roller body 5 is rotatably connected with one end of the shaft rod, namely the roller body rotates relative to the shaft rod.

When the film is on roller 2, the film is receiving the pulling force and rises when rising, and its both sides can the perk sometimes, so through setting up 5 conflicts along its both sides of the roller body, avoid its perk, also further guaranteed the stability of transmission, when the roller body conflicts with the film, it is rotatory to be driven by the film.

The frame body 1 is provided with a sleeve 6 for inserting the shaft rod 4, and the inner wall of the sleeve is provided with a magnetic strip 61.

In the installation, at first install dog 31 and dog two 32 on roller 2, then through certainly passing through both through-holes with axostylus axostyle 4 to insert in the sleeve that corresponds on the support body 1, owing to there is the magnetic stripe in the sleeve, made things convenient for the installation and the dismantlement of axostylus axostyle 4. The shaft 4 is a metal iron rod.

The specific embodiments are only for explaining the present invention, and the present invention is not limited thereto, and those skilled in the art can make modifications without inventive contribution to the present embodiments as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
