Abstract

Disclosed in the present utility model is a protective film attachment fixture with a better film attachment effect, the fixture comprising a fixture body and pull pieces, wherein two ends of the fixture body are each provided with a pull piece slot, with the position of the pull piece slot being higher than an electronic product screen placed in the fixture body. Two pull pieces are respectively inserted into the two pull piece slots; the two pull pieces are arranged opposite each other; front parts of the two pull pieces respectively extend into the fixture body and are suspended above the electronic product screen so as to respectively support two ends of a protective film; and the two pull pieces are respectively pulled outwards to form a control structure that enables the protective film to slowly approach the screen. In the present utility model, both ends of the fixture are directly provided with a pull piece slot, and both sides of the fixture are thus provided with a pull piece, such that the film attachment process is controlled from the two ends of the protective film, so that the leveling of glue will not be affected because one side of the protective film first comes into contact with the screen, such that the leveling of glue is more uniform, in order to improve the accuracy of film attachment, reduce the generation of bubbles, and achieve a better attachment effect.

Description

Protective film attaching fixture with better film attaching effect

Technical field

The utility model relates to the technical field of display screen protection accessories, in particular to a jig used for attaching films to mobile phones and other equipment, such as lamination of liquid glass protective films.

Background technique

With the development of electronic technology, mobile electronic devices represented by smart phones have been used in a wide range of applications. A major feature of such electronic devices is touch operation. Since the display screen needs to be subjected to various operations such as scratching, pressing, and scraping frequently, and sometimes accidental parts such as falling, impact, etc., the risk of damage is high. In order to protect the display screen, a protective film is generally used, such as a tempered glass film. However, the filming operation of the display screen is a very delicate technology, which is not only affected by dust, equipment errors, accessory errors, etc., but also slight movement errors can cause position deviations, air bubbles and other undesirable phenomena. For this reason, many inventors including the applicant have invented some devices for sticking glass films, but the previous film sticking devices are not only complicated in structure, difficult to operate, difficult to accurately locate, and difficult to accurately control the protective film placement process. A simple protective film attaching fixture proposed by the applicant solves the above-mentioned problems, but it only has a pick at one end, so that the other end of the protective film will initially contact the display screen, which will cause the problem of this end. The glue level is not even enough. In addition, because the paddle itself is relatively narrow, the support for a wider protective film is not stable enough, which may cause the protective film to tilt to one side.

实用新型内容Utility model content

The technical problem to be solved by the utility model is to provide a protective film attaching jig with simple structure, more reasonable design, more convenient operation, higher control precision of the filming process, and better filming effect.

In order to solve the above technical problems, the present utility model adopts the following technical solution: a protective film attaching fixture with better filming effect, including a fixture body that can accommodate electronic products and a paddle used to support the protective film. The characteristic lies in that: the two ends of the fixture body are provided with pick grooves, the position of the pick grooves is higher than the electronic product screen placed in the fixture body, by inserting the picks into the two pick slots, the two picks Set opposite each other, and make the front parts of the two paddles extend into the fixture body and hang on the screen of the electronic product or touch the screen to hold the two ends of the protective film respectively, and form by pulling away the two paddles toward the outside. Make the protective film slowly approach the control structure of the screen.

Further, the paddles at both ends are inclined structures, and the outer side of the paddle is higher than the inner side; each end is provided with two paddles, and the two paddles are arranged flush with a distance, and the two paddles are connected as a whole. The support range of the two paddles for the protective film is greater than the sum of the thickness of the two paddles, so that a larger area of the protective film can be supported, and the protective film is prevented from tilting to one side and affecting the filming effect.

Further, a connecting bottom plate is provided at the bottom of the two paddles, through which the two paddles at the same end are connected into an integral structure, and two sides of the connecting bottom plate respectively protrude from the outside of the two paddles to form a guide wing. ; On the upper part of both sides of the paddle slot are formed by the paddle limit edges respectively, the guide wing edges formed by the two sides of the connecting bottom plate are embedded in the paddle limit grooves to form the shape when the paddle is dialed out The moving guide structure enables the paddles to maintain a smooth moving process; the rear ends of the two paddles are connected to each other through a rear connecting edge.
