SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a self-adhesion does not have gluey protection film to solve the problem that proposes in the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a self-adhesion does not have gluey protection film, includes the protection film main part, the bilateral symmetry of protection film main part is connected with tensile membrane and tensile rupture membrane main part, the protection film main part includes first PE electrostatic film, protection film and second PE electrostatic protection film, protection film fixed connection is at the middle part of protection film main part, first PE electrostatic film fixed connection is at the up end of protection film, second PE electrostatic protection film fixed connection is at the lower terminal surface of protection film, tensile rupture membrane main part includes tensile rupture membrane body and pjncture needle, the even symmetric distribution of pjncture needle is on tensile rupture membrane body.
Preferably, the stretch film and the stretch breaking film main body are fixedly connected with the protective film.
Preferably, the interval between the puncture needles is 5 cm.
Preferably, the puncture needle is made of glass.
Preferably, the stretched film and the stretch broken film body are both PE films.
Compared with the prior art, the beneficial effects of the utility model are as follows:
the utility model discloses the both sides of protection film are connected with first PE electrostatic film and second PE electrostatic protection film, first PE electrostatic film and second PE electrostatic protection film use the electrostatic adsorption principle to produce the viscous force, thereby can make the protection film also can bond under the glueless state, stretch film and stretch rupture film main part are the PE membrane, the PE membrane has elasticity, through stretch film and stretch rupture film main part make stretch film and stretch rupture film main part stretch and lengthen, withdraw from external force stretch film and stretch rupture film main part shrink and can adhere to the equipment surface, utilize and pull stretch film and stretch rupture film main part to drive first PE electrostatic film and protection film and move at the equipment surface and can make first PE electrostatic film and protection film produce stronger electrostatic adsorption ability, can know the protection film length of use fast through observing the interval between the pjncture needle, break the pjncture needle so that stretch rupture film body conveniently punctures the fracture of whole membrane body, is convenient to use.

FIG. 1 is a schematic view of the main structure of the present invention;
FIG. 2 is an exploded view of the main body of the present invention;
fig. 3 is a schematic view of the main structure of the stretch breaking film of the present invention.
In the figure: 1-stretching film, 2-protecting film main body, 3-stretching fracture film main body, 4-first PE electrostatic film, 5-protecting film, 6-second PE electrostatic protecting film, 7-stretching fracture film body and 8-puncture needle.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides an embodiment: the utility model provides a self-adhesion does not have gluey protection film, including protection film main part 2, protection film main part 2's bilateral symmetry is connected with tensile membrane 1 and tensile rupture membrane main part 3, protection film main part 2 includes first PE electrostatic film 4, protection film 5 and second PE electrostatic protection film 6, 5 fixed connection at the middle part of protection film main part 2 of protection film, 4 fixed connection of first PE electrostatic film are at the up end of protection film 5, 6 fixed connection of second PE electrostatic protection film are at the lower terminal surface of protection film 5, tensile rupture membrane main part 3 is including tensile rupture membrane body 7 and pjncture needle 8, 8 even symmetric distribution of pjncture needle are on tensile rupture membrane body 7.
The stretching film 1 and the stretching fracture film main body 3 are fixedly connected with the protective film 5, the interval between the puncture needles 8 is 5cm, the puncture needles 8 are made of glass, and the stretching film 1 and the stretching fracture film main body 3 are both PE films.
The working principle is as follows: the two sides of the protection film 5 are connected with a first PE electrostatic film 4 and a second PE electrostatic protection film 6, the first PE electrostatic film 4 and the second PE electrostatic protection film 6 generate adhesive force by using an electrostatic adsorption principle, so that the protection film 5 can be bonded in a glue-free state, both the stretching film 1 and the stretching rupture film main body 3 are PE films, the PE films have elasticity, the stretching film 1 and the stretching rupture film main body 3 are stretched and extended by stretching the stretching film 1 and the stretching rupture film main body 3, the stretching film 1 and the stretching rupture film main body 3 shrink after withdrawing external force so as to be attached to the surface of equipment, the first PE electrostatic film 4 and the protection film 5 can generate stronger electrostatic adsorption capacity by driving the first PE electrostatic film 4 and the protection film 5 to move on the surface of the equipment by pulling the stretching film 1 and the stretching rupture film main body 3, the use length of the protection film 5 can be rapidly known by observing the distance between the puncture needles 8, the puncture needle 8 is broken to puncture the tensile rupture membrane 7, so that the whole membrane can be conveniently ruptured, and the use is convenient.
