Abstract

Disclosed is a novel plastering trowel. The novel plastering trowel comprises a handle, a press strip, a plastering plate piece and a connecting frame. The plastering plate piece is connected with the connecting frame by the press strip. The novel plastering trowel is characterized in that a plurality of connecting pins are connected with one side of the plastering plate piece in a welding mode. The same side of the press strip is provided with a plurality of grooves. The connecting pins are embedded in the grooves each to each and the connecting pins are in interference fit with the grooves. Due to the fact that a connecting structure between the press strip and the plastering plate piece is completely wrapped up and invisible from outside, the whole attractiveness of a product is improved, a polishing procedure in the prior art is avoided as well, and also the end of a rivet is prevented from scratching fingers of a user effectively.

Description

Novel claying knife

Technical field

The utility model relates to a kind of daily building implement, relates in particular to a kind of novel claying knife.

Background technology

Existing claying knife generally is comprised of handle of a knife, press strip, claying plate and link four parts, adopt riveted joint fixing between press strip and the claying plate, this just need to process rivet hole at the claying plate, and after claying knife was made, the claying plate is positive, and (front was claying face, the back side is that face of connection trim strip) can clearly see rivet hole and rivet, affect the attractive in appearance of claying plate, simultaneously, the riveted joint position in claying plate front also needs to polish smooth, cause complex manufacturing technology, cost is higher;

The problem that also exists on the existing claying knife is: link and press strip are overall structure, this structure shape is special, especially the large plane of rivet hole and structure is orthogonal, be difficult to adopt the former batch making, only can be by manually forging, make efficiency is low, and the consistent degree of product design and aesthetics are all relatively poor.

The utility model content

For the problem in the background technology, the utility model proposes a kind of novel claying knife, its basic structure still comprises handle of a knife, press strip, claying plate and link, pass through press strip link between claying plate and the link, handle of a knife is arranged on the link, and its improvement is: the side on the claying plate is welded with a plurality of joint pins, and the homonymy on the press strip is provided with a plurality of grooves, a plurality of joint pins embed in a plurality of grooves correspondingly, and interference fit between groove and the joint pin.After adopting aforementioned structure, claying plate front lighting is sliding, without vestige, saved the polishing operation in the manufacturing process, reduced cost of manufacture, simultaneously, the exposed end of joint pin is hidden by press strip, hand not easy to hang is also so that the claying knife overall aesthetics is better.

For the problem that integrally-built link and press strip exist, the utility model has also been done following improvement: link and press strip are split-type structural, between the two by being welded and fixed.Adopt this structure, the link of absolute construction or press strip shape are comparatively simple, and available plant equipment commonly used is carried out processing and forming, has improved the make efficiency of product, and processes more exquisitely, and the consistent degree of product design is also better.

Based on aforesaid scheme, the utility model has also proposed following preferred link structure: the link profile is L-shaped, and link one end is column structure, and column structure end and press strip are welded and fixed; The link other end is pyramidal structure or threaded stud structure; When adopting threaded stud structure, also be provided with bolt on the threaded column; Handle of a knife or be arranged at the pyramidal structure place perhaps is arranged on the threaded stud structure.When adopting threaded stud structure, handle of a knife directly is socketed in threaded column outer and use bolt tightening, so that the installation of handle of a knife, dismounting are very convenient, is convenient to clean, replacing.When adopting pyramidal structure, directly in the handle of a knife with pyramidal structure end wedging plastic material, install very convenient.

Further, the utility model has also been done following improvement to press strip: be provided with welded post on the press strip, the section area of welded post is less than the section area of column structure end end face on the link; During welding, the part of column structure end end face and welded post welding, the press strip body welding around another part and the welded post.After adopting this structure, the junction between press strip and the link is more firm, stable, the application life of having improved product.

Further, the groove shapes on the press strip is set to bar shaped, and the groove of this structure is so that the interference fit relation between groove and the joint pin is more firm.

Based on aforementioned structure, the utility model has also adopted following preferred material to make the claying plate: described claying plate adopts carbon steel or stainless steel to make.

Useful technique effect of the present utility model is: in the syndeton between press strip and the claying plate is completely wrapped in, outside invisible, this had both improved the overall appearance degree of product, had avoided again polishing operation of the prior art, also can effectively prevent rivet end extension wound finger.

Parts shown in the mark are respectively among the figure: handle of a knife 3, press strip 2, claying plate 1, joint pin 4, groove 5, welded post 6, link 7.

The specific embodiment

A kind of novel claying knife, comprise handle of a knife 3, press strip 2, claying plate 1 and link 7, connect by press strip 2 between claying plate 1 and the link 7, handle of a knife 3 is arranged on the link 7, its improvement is: the side on the claying plate 1 is welded with a plurality of joint pins 4, homonymy on the press strip 2 is provided with a plurality of grooves 5, and a plurality of joint pins 4 embed in a plurality of grooves 5 correspondingly, and interference fit between groove 5 and the joint pin 4.

Further, link 7 and press strip 2 are split-type structural, between the two by being welded and fixed.

Further, link 7 profiles are L-shaped, and link 7 one ends are column structure, and column structure end and press strip 2 are welded and fixed; Link 7 other ends are pyramidal structure or threaded stud structure; When adopting threaded stud structure, also be provided with bolt on the threaded column; Handle of a knife 3 or be arranged at the pyramidal structure place perhaps is arranged on the threaded stud structure.

Usually, but the welding of the column structure end uniform section on welded post and the link 7, in order to improve the fastness of weld, the utility model has also been done following improvement: be provided with welded post 6 on the press strip 2, the section area of welded post 6 is less than the section area of column structure end end face on the link 7; During welding, the part of column structure end end face and welded post 6 welding, the press strip 2 bodies welding around another part and the welded post 6.

Further, described groove 5 is shaped as bar shaped.

Described claying plate 1 adopts carbon steel or stainless steel to make.When claying plate 1 adopts carbon steel, can adopt high-quality blue carbon steel, not only improve the intensity of claying plate 1, also so that the outward appearance of claying plate 1 is more graceful; When claying plate 1 adopts stainless steel, can adopt mirror face stainless steel, product surface light mirror people.
