Abstract

A sleeved leveling device with an anti-skid design is provided with a sleeve portion and a trimming portion formed at one end of the sleeve portion. Anti-skid ribs formed on the inner peripheral surface of the sleeve portion will produce friction with respect to the nozzle of the sealant gun to ensure that the sleeved leveling device can be firmly sleeved on the sealant gun without falling off. An injection hole of the leveling device has an obtuse angle which enables the sealant to flow out successfully even when the user doesn'"'"'t hold the leveling device in a perpendicular position to the surface where a seam to be filled is located. Moreover, the inner trimming surface of the trimming portion is arc-shaped, so that remnant sealant will be collected in the center of the inner trimming surface without overflowing, and the cleanliness of seam-filling operation is assured.

Claims

1. A sleeved leveling device with an anti-skid design comprising a sleeve portion and a trimming portion formed at one end of the sleeve portion;

wherein;

the sleeve portion is a hollow conical structure with a sealant injection end formed at the one end, and another end expands outward to form an annular flange, the sealant injection end is provided with a slanting surface, the sleeve portion includes an outer peripheral surface and an inner peripheral surface, on the inner peripheral surface are formed a plurality of anti-skid ribs;

the trimming portion is formed at the sealant injection end of the sleeve portion and is a triangle structure with a top end and two lateral ends, the top end is an arc-shaped structure with a smooth surface, the trimming portion includes an inner trimming surface and an outer trimming surface, the inner trimming surface is an arc-shaped surface and connected to the slanting surface, an injection hole penetrates from the inner trimming surface to the slanting surface to form an obtuse angle between the inner trimming surface and the slanting surface, the outer trimming surface is connected to the outer peripheral surface of the sleeve portion.

2. The sleeved leveling device with an anti-skid design as claimed in claim 1, wherein a plurality of gripping ribs are formed on the outer peripheral surface of the sleeve portion.

3. The sleeved leveling device with an anti-skid design as claimed in claim 1, wherein a lateral surface is formed between the inner and outer trimming surfaces, and extends from the two lateral ends and tapers toward the top end.
