Description

Technical Field

[0001] This utility model relates to the field of construction tools, specifically to a putty scraper. Background Technology

[0002] A putty scraper is needed to smooth the mortar (including cement, lime paste, putty, etc.) on the wall surface during the slurry application process.

[0003] A putty scraper includes a scraper body and a blade. A groove is made on the scraper body. The rear end of the blade is inserted into the groove as the installation end, and the front end of the blade is the working end for scraping the wall. A retaining groove is provided in the groove, which is used to abut against a card on the blade, thereby restricting the blade from moving forward out of the scraper body.

[0004] The current problem with putty scrapers is that when the blade and the groove of the scraper body are engaged, the rear end of the blade cannot be stably clamped, and the clamping force is insufficient. After the putty scraper has been used continuously for a period of time, the blade is prone to loosening.

[0005] See the prior patent, CN211313262U - A gripping mechanism for a scraper and an irregularly shaped scraper for building decoration. In this patent, although the rear end of the blade is inserted into the groove, the actual part of the groove that can hold the blade is very small. The rear end of the blade and the groove only form point contact, lacking constraint on the rear end of the blade. It can be seen that the blade mounting structure in traditional scrapers is not stable and reliable enough.

[0006] In summary, the current problem is that the blade installation structure in the putty scraper is unstable and prone to loosening. Utility Model Content

[0007] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a putty scraper with easy blade replacement, thereby solving the technical problem that the blade installation structure in the groove of the current putty scraper is unstable and easy to loosen.

[0008] The technical solution adopted by this utility model to solve its technical problem is:

[0009] A putty scraper is provided, including...

[0010] Scraper body and blade;

[0011] The scraper body includes a hand-held part, a blade-mounting part, and a guide part. The blade-mounting part is located below the hand-held part, and the guide part is located in front of the blade-mounting part.

[0012] A tool mounting groove is provided on the front side of the tool mounting part, and a retaining groove is provided in the tool mounting groove. The retaining groove is located above or below the scraper body in the tool mounting groove.

[0013] The total length of the tool mounting groove is L, and the distance between the front end of the tool mounting groove and the slot is L1;

[0014] The L1 ≥ 1 / 2L.

[0015] Furthermore, the lower end of the guide portion is a guide surface, and the tool groove and the guide surface form an obtuse angle structure.

[0016] Furthermore, the distance between the rear end of the tool mounting groove and the slot is L2;

[0017] The L2 is 1 / 3L to 1 / 4L.

[0018] Furthermore, the slot has a triangular or rectangular structure.

[0019] Furthermore, the scraper body is made of plastic.

[0020] Furthermore, the groove spacing of the tool mounting groove is 1.2 to 2.0 mm.

[0021] The beneficial effects of this utility model are:

[0022] The putty scraper of this utility model optimizes and improves the tool mounting groove, making the distance L1 in the tool mounting groove ≥ 1 / 2L, so that the blade can have more assembly contact surface at the front end in the tool mounting groove, making the blade structure in the tool mounting groove more stable and reliable.

[0023] The obtuse angle structure formed between the cutter groove and the guide surface allows the cutter to be in a state of pressure against the guide surface after it is connected to the cutter groove, thus making the cutter more stable to be installed. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] This application provides a putty scraper, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0037] To address the technical problem of unstable installation structure and easy loosening of blades in the blade mounting groove of existing putty scrapers, an embodiment of this application provides a putty scraper. This is described in detail below.

[0038] like Figures 1 to 4 As shown, a putty scraper includes...

[0039] Scraper body 1 and blade 6;

[0040] The scraper body 1 includes a hand-held part 2, a blade-mounting part 4, and a guide part 3. The blade-mounting part 4 is located below the hand-held part 2, and the guide part 3 is located in front of the blade-mounting part 4.

[0041] The blade mounting part 4 has a blade mounting groove 5 on its front side, and a slot 51 is provided in the blade mounting groove 5. The slot 51 is located below the scraper body 1 in the blade mounting groove 5.

[0042] The total length of the tool mounting groove 5 is L, and the distance between the front end of the tool mounting groove 5 and the slot 51 is L1.

[0043] The L1 ≥ 1 / 2L.

[0044] As another implementation of this embodiment, the slot 51 can also be formed above the scraper body 1 inside the blade mounting slot 5.

[0045] like Figure 2As shown, two cards 61 are provided on the rear side of the blade 6. The cards 61 are integral with the blade 6. The cards 61 protrude downward. After the blade 6 is installed in the tool mounting groove 5, the cards 61 are located in the slot 51, thereby restricting the blade 6 from moving forward out of the tool mounting groove 5.

[0046] In this embodiment, the hand-held part 2 includes a first gripping surface 21, a second gripping surface 22 and a third gripping surface 23. The first gripping surface 21 is used for the front ends of four fingers to cooperate, the second gripping surface 22 is used for cooperating with the palm, and the third gripping surface 23 is used for cooperating with the thumb.

[0047] The front and rear sides of the blade mounting part 4 are connected and transitioned to the first gripping surface 21 and the third gripping surface 23, respectively.

[0048] like Figures 1 to 3 As shown, the upper surface of the guide part 3 is connected to the first gripping surface 21, the lower surface of the guide part 3 is the guide surface 31, the guide surface 31 is a plane, and the rear side of the guide surface 31 transitions into the tool groove 5.

[0049] The insertion port of the tool mounting groove 5 is located on the side of the tool mounting part 4. The blade 6 is inserted laterally into the tool mounting groove 5, thereby achieving connection with the tool mounting groove 5. Insertion ports can be formed on both sides of the tool mounting groove 5, but at least one side needs to have an insertion port. In this embodiment, both sides of the tool mounting groove 5 have insertion ports.

[0050] Specifically, as an optional implementation method in this embodiment, such as Figures 1 to 3 As shown, the lower end of the guide part 3 is a guide surface 31, and the tool mounting groove 5 forms an obtuse angle structure with the guide surface 31.

[0051] See Figure 3 As shown, the rear end of the tool mounting groove 5 is point A, the front end of the tool mounting groove 5 is point B, and the front end of the guide surface 31 is point C. The angle formed by the line connecting these three points A, B, and C is an obtuse angle. In this embodiment, the angle between AB and BC is 170°.

[0052] With this obtuse angle structure, when the rear end of the blade 6 is installed in the tool slot 5, point C of the guide part 3 can press the blade 6, and the blade 6 can be elastically pressed onto the guide surface 31, thereby improving the stability of the blade 6 in the guide part 3.

[0053] Specifically, as an optional implementation method in this embodiment, such as Figure 4 As shown, the distance between the rear end of the tool mounting groove 5 and the slot 51 is L2; ​​L2 is 1 / 3L to 1 / 4L.

[0054] The rear end of the blade 6 is a free end, which previously lacked clamping. The rear end of the tool mounting groove 5 has a distance of L2 to provide clamping for the free end of the blade 6, so that the entire blade 6 can be clamped at both the front and rear ends within the tool mounting groove 5, and the clamping area is greatly improved compared to the past.

[0055] Specifically, as an optional implementation method in this embodiment, such as Figure 4 As shown, the card slot 51 has a triangular structure. In this embodiment, the card slot 51 can also be made into a rectangular structure.

[0056] Specifically, as an optional implementation in this embodiment, the scraper body 1 is made of plastic.

[0057] In this embodiment, the groove spacing of the tool mounting groove 5 is 1.2 to 2.0 mm.

[0058] The slot 51 is located on the scraper body 1 below the tooling groove 5, mainly to facilitate the mold making of the scraper body 1. This area below the tooling groove 5 is on the outside of the scraper body 1, and the scraper body 1 in this part is a long, solid structure. This structure is relatively simple and easy to mold. If the slot 51 is located on the scraper body 1 above the tooling groove 5, it is more difficult to mold and inject the scraper body 1. This is because the space above the tooling groove 5 is the center of the scraper body 1, and the middle half is a hollow structure with only one rib inside. Making the slot 51 here makes the injection molding of the scraper body 1 very difficult.

[0059] In this embodiment, the scraper body 1 is made of plastic.

[0060] The scraper body 1 can also be made of metal, with aluminum alloy being a commonly used metal material.

[0061] The putty scraper of this utility model optimizes and improves the blade mounting groove 5 on the scraper body 1, so that the distance L1 in the blade mounting groove 5 is ≥1 / 2L, so that the blade 6 can have more assembly contact surface at the front end in the blade mounting groove 5, making the blade 6 more stable and reliable in the groove.

[0062] Secondly, the obtuse angle structure formed between the tool mounting groove 5 and the guide surface 31 allows the blade 6 to be in a state of pressure against the guide surface 31 after it is connected to the tool mounting groove 5, thus making the blade 6 more stably installed.

[0063] All the devices (parts whose specific structures are not specified) selected in this application are general standard parts or parts known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.
