Description

Part-exchangeable plastering tool}

The present invention relates to a plastering tool used to evenly disperse cement mortar or padade used as a surface finishing material, such as a floor surface or a wall surface of a building.

Plastering tools are known to have a variety of structures and forms, such as trowels and paddles for scratching.

The construction of these tools is divided into a flat plate member, a connecting member and a handle for dispersing and evening the surface finish, and connecting them to form a plastering tool.

When looking at the conventional hairdressing device configured as described above, the flat plate is mainly divided into metal and plastic, and the connection configuration of each part is different according to the type of material.

In particular, plastering tools, such as trowels to configure the plate member connecting member handle separately due to the nature of the structure is to connect them fixed in various ways.

Utility Model Registration No. 20-0371921, "The Trowel" (hereinafter referred to as prior art) is known.

The above prior art is configured to fix a plurality of rivets in the middle portion of the plate member consisting of a metal plate body, and to assemble through rivets through a plurality of holes drilled in the support plate is fixed to the handle.

However, the above-described prior art is a plate structure and the support plate is made of a metal, it is possible to fix the structure using rivets, but in the case of plastics because of the support strength, the assembly or fixing method using the rivets is not desirable.

In addition, since the rivet ball is drilled in the flat plate member, there is a problem in post-processing that requires a smooth rivet through-hole.

In particular, if the material of the plastering tool is plastic, the rigidity cannot be maintained by the rivet assembly method.

In addition, when any one of the flat plate member or the fixing member is unusable due to breakage or the like, there is a problem that the entire plastering tool must be discarded.

The present invention consists of plastic tools in order to effectively solve the above-mentioned problems of the prior art, but divided into a flat plate member and a fixing member handle cover member in consideration of the ease of injection, and each component configured so By assembling and fixing to obtain a durable, lightweight and easy-to-use hairdresser.

And if one part is broken, only the broken part can be replaced and used.

The present invention is to facilitate the injection in consideration that each accessory is made of plastic and to strengthen the assembly portion of each component, and also to facilitate the assembly and disassembly.

In order to achieve the above object, the seating part on which the fixing plate of the fixing member can be firmly seated on the upper surface of the plate member, the piece fixing body on which the fixing plate can be fixed, and the hollow handle part integrally formed with the fixing member on the upper surface of the fixing member; It is constructed by assembling each of the handle cover members to be covered by the hollow handle portion.

The present invention configured as described above is to be configured to be assembled so as to assemble the assembly portion of each accessory to be separately configured to have the effect of greatly improving the durability of the hairdresser itself and simply replace each part.

A fixing plate 21 configured to be fixed to the flat plate member 10 and the upper surface of the flat plate member 10;

A fixing member 20 integrally formed with the fixing plate 21 and having a connecting portion 22 having a handle portion 23 thereon;

The handle part 23 is composed of a handle cover member 30 which is covered on the upper surface.

In the central portion of the upper surface of the flat plate member 10 is composed of both of the piece fixing body 110 and the piece fixing body 110 having a plurality of reinforcing ribs 112 and the reinforcing ribs 112, The fixing plate holder 120 (130) having the 121 and 131 and the fixing plate release preventing rib 140 for preventing the fixing plate from being separated at the front and rear of the piece fixing body 110 are configured.

Protruding jaws 211 and 212 fitted to the fixing plate holders 120 and 130 are formed at both sides of the fixing plate 21 of the fixing member 20.

The handle 23 and the inside of the handle cover member 30 is composed of a hollow portion 40, 50.

In the inner lower portion of the connecting portion 22, there is a piece guide portion 42 and the piece guide portion 42 and the piece guide portion 42 and the piece guide portion 42 formed in the inner upper portion The piece night surface 43 is comprised.

The front and rear of the upper edge of the handle portion 23 is provided with an elastic locking portion 230 having a locking jaw 231.

Front and rear inner surfaces of the lower edge of the handle cover member 30 is provided with a stepped jaw 310 that is caught by the locking step 221.

In the drawings, reference numeral 60 shows a piece for coupling the plate member and the fixing member.

The assembling procedure of the present invention made of the above-described configuration will be described.

The plate member 10, the fixing member 20, the handle cover member 30 is each formed separately.

The protruding jaws 211 and 212 formed on both sides of the fixing plate 21 are caught by the locking step 121 and 131 of the fixing plate holders 120 and 130 formed on both upper surfaces of the flat plate member 10 thus formed. When it is inserted so that the fixed plate 21 is firmly fixed by both of the fixing plate holder 120, 130 and the fixing plate departure preventing rib 140, the piece fixing body 110 formed in the center of the fixing plate 21 is fixed member 20 It is fitted into the piece fixing body 41 formed in the inner lower portion of the connecting portion 22.

When the piece 60 is fixed to the piece hole 111 of the fitted piece fixing body 110 through the piece guide portion 42 formed on the inner upper portion of the connecting portion 22, the piece 60 is a piece supporting surface. The plate member 10 and the fixing member 20 are firmly assembled and fixed to the support 43, and a plurality of reinforcing ribs 112 are formed on the circumferential wall of the piece fixing body 110 so that the plate member 10 can be fixed. Is more firmly supported.

The handle cover member 30 is pressed against the elastic locking portion 230 formed in front and rear of the upper edge of the handle portion 23 formed on the upper portion of the fixing member 20 assembled as described above. The step cover 310 formed on the rear inner surface before the lower rim is coupled to the locking step 231 formed on the elastic locking part 230 of the handle part 23, and the handle cover member 30 is firmly coupled to the plastering tool. do.

The plastering tool of the present invention constituted as described above is separately formed by the accessories constituting the tool into the flat plate member 10, the fixing member 20, and the handle cover member 30, so that the entire plastering tool may be damaged even if any component is damaged during use. It is very economical because it can easily replace only the broken parts by simply separating it without discarding it, and the inside of the fixing member 20 and the handle cover member 30 is composed of hollow parts 40 and 50, thereby saving material. Light weight makes it easy to use
