Abstract

The utility model relates to a plumb bob, which comprises a conical body, wherein the center of the top of the body is provided with a thread tying button, an annular groove is arranged on the conical surface of the body, a leather ring is sheathed in the annular groove, the outermost circle of the leather ring is higher than the conical surface of the body, the body is formed by combining a pointed cone end and a round table end, the annular groove is parallel to the top surface of the body and is positioned at the combined part of the pointed cone end and the round table end, and the pointed cone end and the round table end are combined through forging and pressing. The annular groove parallel to the top surface of the body is arranged on the conical surface of the body, the leather ring is sheathed in the annular groove, the outermost circle of the leather ring protrudes out of the conical surface of the body, the front end or the back end of the plumb bob forms a fulcrum with the leather ring, when the plumb bob rolls on the ground, only the fulcrum is in contact with the ground, the conical surface of the body cannot be easily abraded, and the use effect is good.

Description

A kind of ceiling hammer

Technical field

The utility model relates to surveying and mapping tool, the ceiling hammer that especially a kind of centering is used.

Background technology

Ceiling hammer is a modal aid on the building ground, and the body of wall that it can help the build labourer to make and built is vertical with surface level all the time.And the shape of ceiling hammer generally all is the spindle of standard.

At present a lot of ceiling hammers all are the solid structures, and blanks such as employing wrought iron are processed.Will blank be processed into an end and be the unusual difficulty of the spindle most advanced and sophisticated, that the other end is thicker, especially butt diameter is big more, processes more difficultly, even possibly once get nowhere.Simultaneously, this job operation also can cause very big waste of material, makes cost increase.Therefore elder generation occurred blank is processed into an end for most advanced and sophisticated, spindle that will be thicker adopts the mode of forging and pressing and most advanced and sophisticated the combination to form ceiling hammer, uses lathe that ceiling hammer surface car is smooth smooth then.But there is joint mark in the spindle forging and pressing binding site most advanced and sophisticated, thicker, the not attractive in appearance and influence sale of outward appearance.Ceiling hammer is easy to drop to the ground when using, and the roll surface of easy abrasion ceiling hammer of the ceiling hammer that drops to the ground makes its surface imperfection, and influences attractive in appearance.

Summary of the invention

To the problems referred to above, the ceiling hammer that the utility model provides a kind of surface of rolling on the ground to be not easy to wear and tear, this utility model also has the characteristics of appearance looks elegant.

To achieve these goals, the technical scheme of the utility model employing is following:

A kind of ceiling hammer comprises conical body, is provided with in these bodies top central authorities and fastens the line button; It is characterized in that; The conical surface of said body is provided with a ring groove, in this ring groove, is with the skin ring, and this skin ring outmost turns exceeds the conical surface of said body.

Said body is by pointed cone end and round platform end two parts be combined into, and ring groove is parallel with the end face of said body and be positioned at pointed cone end and round platform end two parts junction.

Said pointed cone end and the forging and pressing of round platform end two parts combine.

The good effect of the utility model:

The conical surface of body is provided with one and body end face parallel annular groove; Skin ring of cover in ring groove, the conical surface of skin ring outmost turns protrusion body, the front end of ceiling hammer or rear end and skin ring constitute fulcrum; When ceiling hammer rolls on the ground; Have only fulcrum to contact with ground, the conical surface of body is not easy wearing and tearing, and result of use is good.

Ring groove is positioned at the forging and pressing junction of pointed cone end and round platform end, cover skin ring in the ring groove, and appearance looks elegant, the sales promotion of being convenient to product is used.

Fig. 1 is existing ceiling hammer structural representation.

Embodiment

Below in conjunction with specific embodiment the utility model is done further explain.

As shown in Figure 1, a kind of ceiling hammer comprises body 1; This body 1 comprises forging and pressing pointed cone end 4 and round platform end 5 together; Be provided with in this body 1 center of top and fasten line button 2, the forging and pressing junction of said pointed cone end 4 and round platform end 5 is provided with a ring groove, and ring groove is parallel with the end face of said body 1; In this ring groove, be with skin ring 3, these skin ring 3 outmost turns exceed the conical surface of said body 1.

The conical surface of body 1 is provided with one and body end face parallel annular groove; Skin ring of cover in ring groove, the conical surface of skin ring outmost turns protrusion body, the front end of ceiling hammer or rear end and skin ring 3 constitute fulcrum; When ceiling hammer rolls on the ground; Have only fulcrum to contact with ground, the conical surface of body is not easy wearing and tearing, and result of use is good.

The foregoing description of the utility model only is to give an example for what explanation the utility model was done, and is not to be the qualification to the embodiment of the utility model.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation and changes.Here can't give exhaustive to all embodiments.Conspicuous variation that every technical scheme that belongs to the utility model is amplified out or change still are in the row of the protection domain of the utility model.
