Description

Multifunctional glue injection tool

Technical Field

The utility model relates to a technical field is repaired to glass, in particular to multi-functional injecting glue instrument.

Background

The repair of cracks or fractures of the automobile windshield is an environment-friendly and rapid repair technology for laminated glass, which is introduced from abroad. When one side of the laminated glass is broken, the photosensitive resin glue can be injected into the crack, and then the ultraviolet curing lamp is used for irradiation and curing, so that the aims of preventing the crack from expanding again and beautifying the surface of the glass can be fulfilled.

The common glass cracks or fractures are summarized into two categories, one is punctiform fractures, namely, the glass surface has a point such as a star or a bubble; the second is a long crack, i.e. a relatively long crack appears on the surface of the glass. When the point-shaped cracks are repaired, a vacuum pump is needed to pump out air in the cracks so that the glue can conveniently permeate into the small cracks, and then the glue is pressed into the cracks by pressurization. When the long-strip cracks are repaired, no special tool is provided at present, glue is usually dripped on the long cracks and then permeates into the long cracks, the repairing time of the method is long, and the glue injection quality cannot be guaranteed.

The existing glass repair tools are mostly in the form of manual vacuum pumps, are relatively troublesome to operate and can be mastered only by long-time practice. The utility model discloses the application number that the people applied for in earlier stage is CN203886751U name is an electronic injecting glue ware and application number is CN204569733U name is full-automatic glass repair device's repair instrument, though can realize electronic injecting glue and restoreed, but still have some problems through long-time observation and practice discovery, if: 1. the two technologies can only carry out glue injection repair on the point-shaped cracks, and can not effectively carry out glue injection on the long cracks. 2. The full-automatic glass restorer is named as CN204569733U, and due to the fact that the full-automatic glass restorer is limited in size, a sensor capable of detecting displacement of a piston rod cannot be installed due to too small internal space, and therefore the problems of locked rotor and tooth slipping after long-term locked rotor often occur; in addition, a special wire or cable is needed for energy supply, and the operation and carrying are inconvenient; and the pressure spring has no fixed object, so that the pressure spring can be frequently dropped out and even lost, and the work is influenced.
