Description

Technical Field

[0001] The utility model relates to the technical field of ceramic scrapers, in particular to a high-strength ceramic scraper. Background Art

[0002] Ceramic scrapers are often used in craft and art projects. They have ceramic blades and are usually made of ceramic material. Ceramic scraper blades are usually more brittle than traditional metal scrapers, but they have the advantage of providing more detailed scraping and carving. These scrapers are often used in pottery, sketching, carving, model making and other fields.

[0003] The handle of some existing ceramic scrapers usually only fixes one end of the blade to facilitate the use of the blade. When the blade is scraping some relatively hard materials, the material is easily deformed under the action of force, and the strength is relatively low. In addition, after using this type of ceramic scraper, it is inevitable that people will forget to clean the blade. After not cleaning it for many times, the blade is easily damaged, which reduces the service life of the blade.

[0004] Therefore, those skilled in the art provide a high-strength ceramic scraper to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a high-strength ceramic scraper is proposed. A plurality of reinforcement blocks are driven by a slider to move along with the blade. When the blade is in use, the blade is supported by a plurality of reinforcement plates, thereby improving the strength of the ceramic scraper. The blade that moves in and out is cleaned by a cleaning mechanism, thereby ensuring the cleanliness of the blade surface at all times and improving the service life of the blade.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-strength ceramic scraper, comprising a ceramic scraper body and a cleaning mechanism, the ceramic scraper body comprising a shell, two rotating plates, a slider, a fixed plate, a blade and a plurality of reinforcing plates, the upper end surface of the slider is provided with a first sliding groove, both sides of the inner wall of the first sliding groove are penetrated by extrusion blocks, the end surfaces on the opposite sides of the two extrusion blocks are fixedly provided with a plurality of pointed blocks, and a first reset spring is fixedly provided between the end surfaces on the opposite sides of the two extrusion blocks;

[0007] The cleaning mechanism includes a cleaning frame, a sliding hole, a plurality of second sponges, two second sliding grooves and two arc blocks, a first sponge is fixedly arranged on one side of the top surface and the inner bottom surface of the sliding hole, a lifting plate is slidably arranged on the opposite side between the inner walls of the two second sliding grooves, three second return springs are fixedly arranged between the two lifting plates and the two second sliding grooves, and three third sponges are fixedly arranged on the end surfaces of the opposite sides of the two lifting plates.

[0008] Through the above technical scheme, the two rotating plates are manually opened, and then the two extrusion blocks are manually pressed toward the middle while moving forward. In the process of pressing the two extrusion blocks, the two extrusion blocks drive the sharp blocks on their surfaces not to abut against the inner wall of the shell, thereby moving the slider in the inner wall of the shell. When it moves to the appropriate position, the pressure on the two extrusion blocks is released. During the use of the blade, the blade outside the shell is supported by the reinforcement plate contacted by both sides of the blade. When the blade or the reinforcement plate is deformed, the bolt can be rotated to remove the fixing plate. At this time, the blade and the reinforcement plate can be replaced. In the process of moving the slider, the two first sponges clean the sharp end surface on one side of the blade, and the multiple second sponges and the multiple third sponges clean the sharp end surface on the front side of the blade. When the arc block abuts against the reinforcement plate, the lifting plate drives the third sponge to move upward, and the multiple third sponges clean the surface of the reinforcement plate, and the multiple second sponges clean the surface of the blade.

[0009] Furthermore, the slider is slidably arranged on the rear side of the inner wall of the housing, a protective shell is fixedly arranged on the upper end surface of the slider, and the two rotating plates are hinged to the housing;

[0010] Through the above technical solution, the hole opened at the upper end of the shell is blocked by two rotating plates, so that dust is prevented from entering the inside of the shell when the blade is not in use, thereby further improving the service life of the blade.

[0011] Furthermore, the rear side of the outer end surface of the blade is slidably disposed in the middle position of the front end surface of the slider, and the rear sides of the outer end surfaces of the plurality of reinforcement plates are respectively slidably disposed in the upper and lower sides of the front end surface of the slider;

[0012] Through the above technical solution, the surfaces of the multiple reinforcing plates are in direct contact with the surface of the blade. When the blade is used, the multiple reinforcing plates support the extended position of the blade, thereby improving the strength of the blade.

[0013] Furthermore, the fixing plate is fixedly connected to the slider by bolts, and the plurality of reinforcing plates and blades are respectively slidably connected to the fixing plate;

[0014] Through the above technical solution, the protrusion at the lower end of the fixing plate is located in the inner walls of the blade and the plurality of reinforcing plates, thereby fixing the plurality of reinforcing plates and the blades together in the inner wall of the sliding block.

[0015] Furthermore, the rear end surface of the cleaning frame is fixedly arranged on the front end surface of the shell, the sliding hole is opened in the middle position of the front end surface of the cleaning frame, and a plurality of the second sponges are respectively fixedly arranged on both sides and the middle position of the top surface and the inner bottom surface of the sliding hole;

[0016] Through the above technical solution, by setting the third sponge and the second sponge to be in a disconnected state, the slider can fully clean different positions of the blade during the movement.

[0017] Furthermore, the two sliding grooves are respectively provided on the upper side and the lower side of the front end surface of the cleaning frame, and the two arc blocks are respectively fixedly connected to the two lifting plates;

[0018] Through the above technical solution, the arc-shaped end of the reinforcing plate abuts against the arc-shaped block, and the lifting plate is moved upward during the movement of the slider, so that the multiple third sponges do not block the multiple reinforcing plates.

[0019] The utility model has the following beneficial effects:

[0020] 1. The utility model proposes a high-strength ceramic scraper. After opening the rotating plate, the two extrusion blocks are manually pressed toward the middle while moving toward the front side. During the movement, the slider is driven to move in the inner wall of the shell. When it moves to a suitable position, the pressure on the two extrusion blocks is released. Under the action of the first return spring, the protrusion at one end of the extrusion block re-enters the inner wall of the shell, thereby fixing the slider. When the blade is in use, multiple reinforcement plates support the blade extending out of the shell, thereby improving the strength of the blade. When the blade or the reinforcement plate is damaged, the bolt can be rotated to release the fixing plate from fixing the blade and the reinforcement plate, and the two can be replaced.

[0021] 2. The utility model proposes a high-strength ceramic scraper. During the movement of the slider, the sharp end of one side of the blade is cleaned by two first sponges arranged on one side of the sliding hole, and the sharp end of the front side of the blade is cleaned by multiple second sponges arranged in the sliding hole and multiple third sponges on the end surface of the lifting plate. When the reinforcement plate lifts the lifting plate upward through the arc block, the third sponge cleans the surface of the reinforcement plate, and the second sponge cleans the remaining blade surface. The cleaning mechanism cleans the blade that moves back and forth, thereby ensuring the cleanliness of the blade surface and increasing the service life of the blade.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1-6 The utility model provides an embodiment: a high-strength ceramic scraper, including a ceramic scraper body 1 and a cleaning mechanism 2, the ceramic scraper body 1 includes a shell 101, two rotating plates 102, a slider 103, a fixed plate 109, a blade 111 and a plurality of reinforcement plates 112, the upper end surface of the slider 103 is provided with a first sliding groove 104, the inner walls on both sides of the first sliding groove 104 are penetrated by extrusion blocks 105 that are slidably arranged, the end surfaces of the opposite sides of the two extrusion blocks 105 are fixedly provided with a plurality of pointed blocks 106, and a first return spring 107 is fixedly arranged between the end surfaces of the opposite sides of the two extrusion blocks 105, the slider 103 is slidably arranged on the rear side of the inner wall of the shell 101, the upper end surface of the slider 103 is fixedly provided with a protective shell 108, and the two rotating plates 102 are hinged to the shell 101.

[0032] The holes opened at the upper end of the shell 101 are blocked by the two rotating plates 102 to prevent dust from entering the inside of the shell 101 when the blade 111 is not in use, thereby further improving the service life of the blade 111. After opening the two rotating plates 102, the two extrusion blocks 105 are manually pressed toward the middle. At this time, the sharp blocks 106 at one end of the two extrusion blocks 105 leave the inner wall of the shell 101, and then the two extrusion blocks 105 can be continued to be pressed while holding the extrusion blocks 105 and moving them to the front side, thereby driving the slider 103 to move in the inner wall of the shell 101. When they move to the appropriate position, the pressure on the two extrusion blocks 105 is released. Under the action of the first return spring 107, the sharp block 106 at one end of the extrusion block 105 is pushed into the inner wall of the shell 101 again, thereby fixing the slider 103.

[0033] The rear side of the outer end surface of the blade 111 is slidably disposed in the middle position of the front end surface of the slider 103, and the rear sides of the outer end surfaces of multiple reinforcement plates 112 are respectively slidably disposed on the upper and lower sides of the front end surface of the slider 103. The surfaces of the multiple reinforcement plates 112 are in direct contact with the surface of the blade 111. When the blade 111 is used, the position where the blade 111 is extended is supported by the multiple reinforcement plates 112, thereby improving the strength of the blade 111. The fixing plate 109 is fixedly connected to the slider 103 by bolts 110, and the multiple reinforcement plates 112 and the blade 111 are respectively slidably connected to the fixing plate 109. The protrusion at the lower end of the fixing plate 109 is located in the inner wall of the blade 111 and multiple reinforcement plates 112, so that the multiple reinforcement plates 112 and the blade 111 are fixed together in the inner wall of the slider 103. When the blade 111 or the reinforcement plate 112 needs to be replaced, the slider 103 is manually moved to the front side. At this time, the bolt 110 can be rotated to release the fixation of the slider 103 to the fixing plate 109. At this time, the fixing plate 109 is taken out, and the three protrusions on the lower side of the fixing plate 109 leave the inner wall of the blade 111 and multiple reinforcement plates 112. At this time, the blade 111 and the multiple reinforcement plates 112 can be replaced.

[0034] The cleaning mechanism 2 includes a cleaning frame 201, a sliding hole 202, a plurality of second sponges 204, two second sliding grooves 205 and two arc blocks 209. The first sponge 203 is fixedly arranged on one side of the top surface and the inner bottom surface of the sliding hole 202, a lifting plate 206 is slidably arranged on the opposite side between the inner walls on both sides of the two second sliding grooves 205, three second return springs 208 are fixedly arranged between the two lifting plates 206 and the two second sliding grooves 205, and three third sponges 207 are fixedly arranged on the end surfaces of the opposite sides of the two lifting plates 206. The rear end surface of the cleaning frame 201 is fixedly arranged on the front end surface of the shell 101, the sliding hole 202 is opened in the middle position of the front end surface of the cleaning frame 201, the plurality of second sponges 204 are respectively fixedly arranged on both sides and the middle position of the top surface and the inner bottom surface of the sliding hole 202, the two sliding grooves are respectively opened on the upper side and the lower side of the front end surface of the cleaning frame 201, and the two arc blocks 209 are respectively fixedly connected to the two lifting plates 206.

[0035] When the slider 103 moves forward, the sharp end of the front side of the blade 111 first enters the sliding hole 202, and then enters between the plurality of second sponges 204 and the plurality of third sponges 207. During the movement of the slider 103, the surface of the sharp end is cleaned by the plurality of second sponges 204 and the plurality of third sponges 207. When the slider 103 slides to the front arc end of the reinforcing plate 112 and abuts against the arc block 209, the arc block 209 is driven to move upward. During the movement, the arc block 209 drives the lifting plate 206 to move together, so that The third sponge 207 integrated with the lifting plate 206 is made to enter the second sliding groove 205. At this time, the multiple second sponges 204 clean the other surfaces of the blade 111, and the multiple third sponges 207 clean the surface of the reinforcing plate 112. The sharp end of one side of the blade 111 is cleaned through the upper and lower two first sponges 203. When the slider 103 slides back, the multiple second sponges 204 first clean the surface of the blade 111, and then the multiple third sponges 207 clean the sharp end of the front side of the blade 111.

[0036] Working principle: manually open the two rotating plates 102, then press the two squeezing blocks 105 toward the middle while moving the squeezing blocks 105 to the front. When the blade 111 extends to a suitable length, release the pressure on the two squeezing blocks 105. At this time, hold the shell 101 and use the blade 111. After use, press the two squeezing blocks 105 toward the middle while moving them to the rear. When they are moved to the tail, release the pressure on the two squeezing blocks 105, and then close the two rotating plates 102. In the process of moving the slider 103, the entire surface of the blade 111 is cleaned by two first sponges 203, multiple second sponges 204 and multiple third sponges 207. When replacing the blade 111 or the reinforcement plate 112, first slide the slider 103 to the front, then rotate the bolt 110 to remove the fixing plate 109. At this time, the reinforcement plate 112 and the blade 111 can be replaced.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
