[0032] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme of the utility model will be described clearly and completely in combination with the drawings below. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0033] The application provides a novel putty scraping plate, which is described in detail below. It should be noted that the description order of the following embodiments is not limited as the preferred order of the embodiments of the application. In the following embodiments, the description of each embodiment has its own emphasis, and the parts not described in detail in a certain embodiment can be referred to the related description of other embodiments.

[0034] To solve the technical problem that the side cover of the putty scraping plate is inconvenient to disassemble and assemble, thereby affecting the efficiency of blade replacement, an embodiment of the application provides a novel putty scraping plate. The following is described in detail.

[0035] As shown in Figures 1 to 5 A novel putty scraping plate comprises

[0036] a scraping plate body 1 and a blade;

[0037] A blade groove 11 is formed on the scraping plate body 1, and the blade groove 11 forms a front opening and at least one side opening on the scraping plate body 1. The blade is adapted to be inserted into the blade groove 11 from the side opening, and the blade extends from the front opening.

[0038] At least one end cover 22 is arranged at the end side of the scraping plate body 1.

[0039] A side cover 3 is rotatably connected to the end cover 22 through a pin shaft 32 at one end of the side cover 3. The side cover 3 is provided with an open position and a closed position on the end cover 22. When the side cover 3 is rotated to the open position, the side opening of the blade groove 11 is opened. When the side cover 3 is rotated to the closed position, the side cover 3 shields the side opening of the blade groove 11.

[0040] A buckle structure is arranged between the side cover 3 and the end cover 22. When the side cover 3 is rotated to the closed position, the side cover 3 is buckled with the end cover 22 to position the side cover 3 at the closed position.

[0041] In this embodiment, the scraping plate body 1 belongs to the prior art, which comprises a hand-held part, a guide part and a blade mounting part. The blade groove 11 is arranged in the blade mounting part, and the scraping plate body 1 is integrally formed by plastic injection molding or aluminum alloy pouring.

[0042] Specifically, as an optional implementation in the embodiment, the blade slot 11 forms two side openings on the blade body 1, and both ends of the blade body 1 are provided with end covers 22, one of which directly seals the side opening, and the other side end cover 22 is provided with a side cover 3.

[0043] Specifically, as an optional implementation in the embodiment, as shown in Figure 2 and Figure 3 , the end cover 22 is provided with an assembly groove 21, which is a stepped groove;

[0044] Both sides of the assembly groove 21 are respectively provided with shaft holes 22, and both sides of the side cover 3 are respectively provided with pin shafts 32, which are inserted into the shaft holes 22, so that the side plate is rotationally matched in the assembly groove 21.

[0045] In the embodiment, the end cover 22 cooperates with the side cover 3 through the stepped groove, which can make the installation structure of the side cover 3 on the end cover 22 more stable and reliable.

[0046] In the embodiment, the rotation angle of the side cover 3 on the end cover 22 is ≥90°, which needs to ensure that when the side cover 3 is in the open position, the free end of the side cover 3 does not interfere with the entry and exit of the blade into the blade slot 11.

[0047] Specifically, as an optional implementation in the embodiment, as shown in Figure 4 and Figure 5 , the inner side of the side cover 3 is provided with an inner boss 31 at the front end, and when the side cover 3 is in the closed position, the inner boss 31 moves to the front side of the side opening of the blade slot 11.

[0048] The design of the inner boss 31 can make the side cover 3 block cover directly fit to the side opening when shielding the blade slot 11, so that the side cover 3 shields the blade slot 11 more comfortably.

[0049] Specifically, as an optional implementation in the embodiment, as shown in Figures 3 to 5 , the buckle structure includes a clamping groove 41 and a clamping convex 42;

[0050] The clamping groove 41 is arranged on the end cover 22, and the clamping convex 42 is arranged on the side cover 3.

[0051] When the side cover 3 is rotated to the closed position, the clamping convex 42 enters the clamping groove 41, thereby positioning the baffle and limiting its rotation in the closed position.

[0052] Similarly, the clamping groove 41 can also be arranged on the side cover 3, and the clamping convex 42 is arranged on the end cover 22, and the technical effects of the two are the same.

[0053] Specifically, as an optional implementation in the embodiment, as shown in Figure 4 , the side cover 3 is provided with a convex rib 33 at the front end.

[0054] The convex rib 33 is designed to facilitate the operator to open the side cover 3 from the closed position, when the side cover 3 is in the closed position, the convex rib 33 protrudes forward to the blade body 1, and the operator can open the side cover 3 by one hand.

[0055] Specifically, as an optional embodiment in the embodiment, as shown in Figure 4 and Figure 5 The pin shaft 32 and the side cover 3 are in an integrated structure; and the pin shaft 32 is provided with a guide inclined surface 321.

[0056] The design of the guide inclined surface 321 facilitates the pressing assembly of the side cover 3 into the assembly groove 21, since the assembly groove 21 is a stepped groove, the side cover 3 is just in the assembly groove 21, and when the side cover 3 is installed with the assembly groove 21, the side cover 3 is pressed into the assembly groove 21, if the pin shaft 32 is a cylinder, it is more difficult to press into the assembly groove 21, and now the guide inclined surface 321 is arranged on the pin shaft 32, which facilitates the installation of the side cover 3 into the assembly groove 21.

[0057] Secondly, in order to facilitate the installation of the side cover 3 into the assembly groove 21, the shaft hole 22 in the assembly groove 21 is a long slot hole.

[0058] The putty scraping plate of the utility model uses the following method:

[0059] When the blade needs to be disassembled, the side cover 3 is opened, then the blade is inserted into or taken out of the blade groove 11, and after the disassembly of the blade is completed, the side cover 3 is rotated to the closed position, the clamping convex 42 is matched with the clamping groove 41, so that the side cover 3 is positioned and fixed, and the side cover 3 is prevented from being opened at will.

[0060] In the present application, each device (parts without specific structure) is a general standard part or a part known to those skilled in the art, and its structure and principle can be known by the technical personnel through the technical manual or through the conventional experimental method.
