Description

Sleeve scraper

Technical Field

The utility model relates to an aviation sealant construction technical field especially relates to sleeve scraper.

Background

The fasteners are important components of a fuel tank structure and are numerous, the mounting positions of the fasteners are often areas where fuel easily leaks, in order to meet related safety requirements, the joints of the fasteners and the fuel tank also need to be sealed through sealant, the sealant covers the ends of the fasteners to form package sealing, and for removing cured fastener sealant packages, at present, similar tools are not available, the operation is purely manual, and time and labor are wasted; due to space limitation, the tool cannot completely meet the use requirement of a narrow space when manual operation is carried out at present; in manual operation, the operation process cannot be controlled, and destructive damage can be caused to the surface of a fastener or other materials in the operation process; the sealant at most positions is difficult to remove in manual operation and cannot be completely removed; other hand tools consume too fast and are costly to use.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects existing in the prior art and providing a sleeve scraper.

In order to realize the purpose, the utility model adopts the following technical scheme: the sleeve scraper comprises an annular protective sleeve, wherein the top of the annular protective sleeve is fixedly connected with a connecting rod, and the inner part of the annular protective sleeve is fixedly connected with four groups of symmetrically arranged blades.

As a further description of the above technical solution:

four hollow areas which are arranged in an annular array are arranged at the top of the annular protective sleeve.

As a further description of the above technical solution:

six grooves which are arranged in an annular array are formed in the outer surface of the connecting rod.

As a further description of the above technical solution:

the blade shape is the cockscomb structure, blade bottom extends to the annular protective sheath outside, and blade bottom is for leveling the setting.

As a further description of the above technical solution:

the centers of the four groups of blades are arranged in a crossed stacking mode.

The utility model discloses following beneficial effect has:

compared with the prior art, the sleeve scraper can be converted from pure manual operation into automatic operation, can automatically position the center of a fastener in the removing process, quickly remove the surrounding sealant, greatly improve the working efficiency, and protect metal materials around the fastener from being scratched in the operating process; in addition, the high-strength plastic material is adopted for injection molding, so that the use cost is low, the service life is long, and the operation cost is reduced while the labor and time are saved.

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. 1-4, the utility model provides a sleeve scraper: including annular protective sheath 1, the top fixedly connected with connecting rod 2 of annular protective sheath 1, the blade 3 of four group of symmetrical arrangement of inside fixedly connected with of annular protective sheath 1, the preparation is moulded plastics to the scraper adoption high strength material, can not cause the fastener damage.

Four hollow areas 4 that are the annular array and arrange are seted up at the top of annular protective sheath 1, and six recesses 5 that are the annular array and arrange are seted up to the surface of connecting

rod

2, and 3 shapes of blade are the cockscomb structure, and 3 bottoms of blade extend to annular protective sheath 1 outsidely, and 3 bottoms of blade are for leveling the setting, and 3 central departments of four groups of blades are the setting of piling up for the crossing.

The working principle is as follows: the connecting rod 2 is arranged and used for connecting various clamping tools, six groups of grooves 5 are formed around the connecting rod 2, so that the connecting rod 2 is prevented from slipping during construction after clamping, the structural strength of the connecting rod 2 is ensured, the annular protective sleeve 1 on the periphery of the blade 3 can reduce the splashing range of materials in the sealant removing process, so that the cleaning and the safety of operators are protected, the size of the blade 3 is higher than that of the annular protective sleeve 1, the sealant removing condition in the construction process is ensured, the blade 3 is serrated, fasteners can be attached to different angles in the rotary construction process for removing, the bottom of the blade 3 is sharp and flat, the metal materials around the fasteners can be protected from being scratched in the operation process, the centers of a plurality of groups of blades 3 are in a crossed stacking design, the fasteners can be centrally positioned in the construction process, the top of the annular protective sleeve 1 is in a hollowed-out design, the removed sealant debris can be discharged during construction.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
