Specific embodiment
In order to be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, tie below
Specific embodiment is closed, the present invention is further explained.
Such as Fig. 1-2, a kind of lossless connector of plastic film of the present embodiment, including mainboard 1, main shaft 2, clamping plate 3, supporting plate 4,
Telescopic rod 5, torsion bar 6 and bar 7, there are two square breach, mainboards 1 for the setting of the front side of square plate and mainboard 1 for the mainboard 1
On be provided with bracket 11；11 quantity of bracket is two, and one of bracket 11 is located on the left of the top surface of mainboard 1, and another
A bracket 11 is located on the right side of the bottom surface of mainboard 1；Front end of the main shaft 2 from front to back through the middle part of mainboard 1 and main shaft 2 is set
It is equipped with cavity, quarter butt is provided in the cavity and is slidably connected with it；3 quantity of clamping plate is two and the two clamping plates 3
Middle part is respectively hinged on two brackets 11, and clamping plate 3 has elastic force；4 quantity of supporting plate is two, and the two supporting plates 4 divide
Not hinged close to the side of main shaft 2 with two clamping plates 3, which is located at the gap position on mainboard 1, which can make
The rotation of supporting plate 4 is unaffected；5 quantity of telescopic rod be two, one end of the two telescopic rods 5 respectively with two supporting plates 4
The other side it is hinged；The both ends of the torsion bar 6 are connect respectively with two telescopic rods 5 and the center of torsion bar 6 is hinged on 2 front end of main shaft
Quarter butt on, pole 61 is provided on torsion bar 6；61 quantity of pole is two, and torsion bar 6 is arranged in one of pole 61
Left end and certain angle is tilted along clockwise direction, the right end of torsion bar 6 and along clockwise direction is arranged in another pole 61
Tilt certain angle；7 quantity of bar is two, the two bars 7 are separately positioned on the rear side of two poles 61.
Such as Fig. 1-2,3, two, two clamping plates pole 61 of supporting plate 4, two and two bars 7 are in about main shaft 2
Central symmetry.When extending to longest, bar 7 is not blocked by mainboard 1 telescopic rod 5 in a bird's eye view.The mainboard 1
Square breach area be greater than supporting plate 4 area.
In the use of the present invention, plastic film can be placed between clamping plate 3 and mainboard 1 by user, it is pulled along torsion bar
6, torsion bar 6 drives telescopic rod 5 and the quarter butt of 2 front end of main shaft flexible, and bar 7 is drawn out with the pulling of torsion bar 6 and regards overlooking
It is not blocked by mainboard 1 in angle, rotates clockwise torsion bar 6, torsion bar 6 drives supporting plate 4 to operate, and the side of clamping plate 3 and supporting plate 4 are hinged
And middle part is hinged on bracket, therefore supporting plate 4 is supplied to the power that clamping plate 3 rotates counterclockwise, then clamping plate 3 and mainboard 1 are by plastics
Film clamping tightly.Torsion bar 6 is urged rearwardly into, blocks the bar 7 on right side which by mainboard 1 in a bird's eye view, then torsion bar 6
Both ends are blocked by mainboard 1, clamping plate 3 by supporting plate 4 drive and generate upward elastic force, bar 7, which blocks clamping plate 3, makes baffle 3
It can not move, therefore can realize self-locking because of elastic force.When needing to remove plastic film, similarly, pulls out torsion bar 6 and rotate counterclockwise
Torsion bar 6, then clamping plate 3 is separated with mainboard 1, extracts plastic film out.
The basic principles, main features and advantages of the invention have been shown and described above.The technical staff of the industry should
Understand, the present invention is not limited to the above embodiments, and the description in above embodiment and specification only illustrates the present invention
Principle, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these variation and
Improvement is both fallen in the scope of protection of present invention.The claimed scope of the invention is by appended claims and its equivalent
Object defines.
