Description

Technical Field

[0001] This invention relates to the field of ceramic forming equipment technology, specifically a potter's wheel for producing ceramic handicrafts. Background Technology

[0002] Existing pottery wheels mainly consist of a base, a turntable for throwing, a mudguard, a motor as the power source, and a speed regulator to adjust the rotation speed of the turntable. During the throwing process, clay is placed on the turntable, and the rotation of the turntable pulls the clay into a blank.

[0003] Traditional pottery wheels have legs fixedly connected to the bottom of the base, which lifts the wheel off the ground. However, the height of a pottery wheel is generally suitable for people to sit down while pulling the pot. If people need to pull the pot while standing, the overall height of the pottery wheel cannot be changed because the legs are fixed.

[0004] Therefore, the applicant has developed a new technical solution in the actual production process to solve the above-mentioned technical problems. Summary of the Invention

[0005] To address the aforementioned technical shortcomings, the purpose of this invention is to provide a potter's wheel for producing ceramic handicrafts, which has the advantage of allowing for the easy installation of support legs of different heights onto the potter's wheel base as needed.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] This invention provides a potter's wheel for producing ceramic handicrafts, including a base, a rotating shaft rotatably connected to the base, and a turntable coaxially fixed at the upper end of the rotating shaft. Two semi-circular basins are placed on the upper surface of the base, located on the left and right sides of the turntable. Several vertically distributed connecting cylinders are provided at the lower end of the base. Each connecting cylinder has a leg slidably connected to it. Each connecting cylinder has an elongated groove distributed along its height. The upper outer wall of each leg is connected to a pressing post that matches the width of the elongated groove via a telescopic component. When the pressing post moves out of the elongated groove, a connecting component on the connecting cylinder allows the leg to be detached from the connecting cylinder by rotating it. When the pressing post is in the elongated groove, the connecting component locks the upper end of the leg inside the connecting cylinder.

[0008] The connector includes several limiting strips arranged circumferentially on the inner wall of the connecting cylinder. Each limiting strip is distributed along the length of the connecting cylinder. The upper end of the support leg is provided with an arc-shaped groove for the corresponding limiting strip to be inserted. The bottom of the arc-shaped groove is fixedly embedded with a long strip plate on one side of the limiting strip. The long strip plate is located on one side of the limiting strip and is in contact with one side of the limiting strip. At this time, the pressing column is staggered with the long strip groove. Both the long strip plate and the limiting strip are provided with several support plates spaced apart along the length of the long strip plate or the limiting strip. The support plates on the long strip plate correspond to the spatial distribution between two adjacent support plates on the limiting strip.

[0009] By adopting the above technical solution, the connecting cylinder provided on the lower end face of the machine base is intended to facilitate connection with support legs of various heights. The pressing column moves within the elongated groove, thereby facilitating the adjustment of the height of each support leg. Furthermore, the connecting component is designed to allow for easy disassembly of the support leg by simply releasing the engagement between the pressing column and the elongated groove and rotating it slightly. This makes operation convenient. After the support leg is installed, the pressing column enters the elongated groove, at which point the connecting component acts as a limit and lock for the support leg, thereby installing the support leg within the connecting cylinder. This achieves the goal of easily installing support legs of different heights onto the machine base of the potter's wheel according to requirements.

[0010] Preferably, the telescopic component includes a telescopic groove formed on the outer wall of the outrigger, one end of the pressing column is slidably connected in the telescopic groove, a second compression spring is provided at the bottom of the telescopic groove, and the end of the second compression spring away from the bottom of the telescopic groove is fixed on the pressing column. When the second compression spring is in its natural state, the pressing column is located in the elongated groove, and the end of the pressing column extending out of the elongated groove is spherical.

[0011] Preferably, the support leg is a vertically distributed rod, or the support leg has a vertically distributed rod at the top, a rod that extends obliquely away from the base in the middle, and a vertically distributed rod at the bottom. When the pressing column enters the elongated groove, the part of the support leg that extends obliquely away from the base is exactly in the predetermined position.

[0012] Preferably, each of the two semi-circular basins includes an annular wall 1 and an annular wall 2 distributed coaxially inside and outside. The diameter of the annular wall 1 is smaller than the diameter of the annular wall 2, and the height of the upper end of the annular wall 1 is lower than the height of the upper end of the annular wall 2. The bottom of the outer wall of the annular wall 1 and the bottom of the inner wall of the annular wall 2 are connected by a semi-circular base plate. The height of the lower end of the outer wall of the annular wall 2 is higher than the height of the base plate.

[0013] One of the basins has an annular wall 2 on one side relative to the annular wall 2 of the other basin, which is provided with a plug that can be inserted into the other annular wall 2. Each basin has only one plug. The lower end of the annular wall 2 is provided with a release element to release the connection between the plug and the other annular wall 2.

[0014] When the two basins are assembled into a complete circular basin, the annular wall is located below the surface of the turntable.

[0015] Preferably, the lower end faces of both the first annular wall and the second annular wall are provided with cavities, and the cavities extend out of the lower end faces of the first annular wall and the second annular wall;

[0016] The release mechanism includes a rectangular frame disposed within the cavity of the second annular wall. One side of the rectangular frame abuts against the inner wall of the second annular wall that is close to the other second annular wall, and the upper end of the rectangular frame is closed. A sliding plate is connected to the rectangular frame by sliding up and down. The upper end of the sliding plate is provided with a compression spring connected to the upper inner wall of the rectangular frame. The second annular wall has a slot on its side facing the other second annular wall that extends into the rectangular frame and is used for inserting the plug. The sliding plate has a placement groove corresponding to the plug. A retaining plate is provided on the upper wall of the placement groove. A retaining groove is provided on the upper surface of the plug for the retaining plate to be engaged.

[0017] The lower end of the slide plate extends from the lower end of the outer wall of the second annular wall, and there is a gap between the lower end of the slide plate and the upper end face of the base.

[0018] Preferably, the upper and lower ends of the insert block are provided with inclined surfaces. The provision of two inclined surfaces reduces the size of the end of the insert block. The end of the insert block is distributed away from the basin of the fixed insert block. The lower end of the card plate is provided with an inclined surface that cooperates with the inclined surface of the upper end of the insert block.

[0019] Preferably, the second annular wall and the rectangular frame both have elongated guide grooves distributed vertically below the slot. The slide plate is threaded with screws that move up and down in the guide grooves. The guide grooves are symmetrically distributed on both sides of the rectangular frame. The upper end of the slide plate is in contact with the lower end of the compression spring.

[0020] Preferably, the slide plate has a plurality of threaded holes that are threaded to connect with screws, and the threaded holes are arranged along the height direction of the slide plate.

[0021] Preferably, it also includes baffles at both ends of the two basins, the two baffles being connected to both ends of the bottom plate respectively, and the baffles being connected to the inner walls of the first annular wall and the second annular wall respectively. Each baffle of the basin is provided with a rod that can be inserted into the baffle of the other basin, and the other baffle is provided with a hole for inserting the rod. The two baffles on each basin: one baffle is provided with a rod, and the other baffle is provided with a hole. The holes on the baffles are connected to the cavity of the first annular wall and are distributed close to the slot.

[0022] Preferably, the second annular wall is provided with a detection element for detecting whether the rotating disc rotates smoothly.

[0023] Preferably, the detection component includes an inverted U-shaped fixing plate inserted into the outer wall of the second annular wall. There are gaps between the two vertical walls of the fixing plate and the inner and outer walls of the second annular wall. The fixing plate has a wooden board and a wooden cylinder on one of the vertical walls inside the second annular wall. The wooden board and the cylinder are horizontally distributed and the wooden board is located above the cylinder. The fixing plate is provided with a driving component that drives the wooden board and the cylinder to move up and down or horizontally.

[0024] Preferably, the driving component includes a screw rod that passes through the horizontal wall of the fixed plate. The lower end of the screw rod is screwed into the upper end face of the second annular wall and enters the cavity of the second annular wall. Locking blocks are threadedly connected to both the upper and lower sides of the horizontal wall of the fixed plate. A limiting block that abuts against the upper end face of the second annular wall is threadedly connected to the outer wall of the screw rod.

[0025] The horizontal wall of the fixed plate is provided with an elongated adjustment groove for the screw to slide horizontally. When the screw moves in the adjustment groove, the fixed plate moves in a direction that is closer to or farther from the turntable.

[0026] Preferably, the base has several elongated mounting slots on both sides of the basin that extend through the upper and lower edges of the base. The base is fitted with a water box through the mounting slots. The opening of the water box faces upward. One side wall of the water box is provided with an insert plate that can be inserted into the mounting slot. The mounting slot is located at the lower end of the annular wall.

[0027] The beneficial effects of the present invention are as follows: the connecting cylinder provided on the lower end face of the machine base is intended to facilitate connection with support legs of various heights. The pressing column moves in the elongated groove, thereby facilitating the adjustment of the height of each support leg. Furthermore, the setting of the connecting piece makes it easy to disassemble the support leg by simply rotating it after releasing the engagement between the pressing column and the elongated groove. The operation is convenient. After the support leg is installed, the pressing column enters the elongated groove. At this time, the connecting piece plays a limiting and locking role on the support leg, thereby installing the support leg in the connecting cylinder. This achieves the purpose of facilitating the installation of support legs of different heights onto the machine base of the potter's wheel according to requirements.

[0028] Furthermore, when installing the outriggers, the outriggers and connecting cylinders can be installed and removed with a simple press and turn operation, which is simple and convenient. After the connecting cylinder and outriggers are installed, they are supported by interlocking support plates, forming a stable support force for the connecting cylinder; and the press and turn operation allows the support plates to be positioned differently, thus facilitating the adjustment of the outrigger height.

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] A potter's wheel for producing ceramic handicrafts, such as Figure 1 and Figure 2 The system includes a base 1, a rotating shaft rotatably connected to the base 1, and a turntable 11 coaxially fixed at the upper end of the rotating shaft. The base 1 is equipped with a motor that drives the rotating shaft to rotate. These are all existing technologies and will not be described in detail here. Two semi-circular basins 12 are placed on the upper surface of the base 1, located on the left and right sides of the turntable 11. The basins 12 are placed on the upper surface of the base 1. When the two semi-circular basins 12 are closed together, they form a complete circular mud-blocking basin that surrounds the turntable 11.

[0048] like Figure 1 and Figure 2The base 1 is a plate with a semi-circular shape at one end and a rectangular shape at the other end. Several vertically distributed connecting cylinders 2 are fixedly provided at the lower end of the base 1. Each connecting cylinder 2 has a support leg 21 that slides through it. Each connecting cylinder 2 has a long strip groove 22 distributed along the height direction of the connecting cylinder 2. There is only one long strip groove 22. The upper outer wall of the support leg 21 is connected to a pressing post 221 that matches the width of the long strip groove 22 through a telescopic component. That is, when the pressing post 221 is located in the long strip groove 22, it can restrict the rotation of the support leg 21 in the connecting cylinder 2. When the pressing post 221 is moved out of the long strip groove 22, the connecting cylinder 2 has a connecting component that can remove the support leg 21 from the connecting cylinder 2 by rotating the support leg 21. When the pressing post 221 is in the long strip groove 22, the connecting component locks the upper end of the support leg 21 in the connecting cylinder 2.

[0049] like Figure 3 and Figure 4 and Figure 5 and Figure 6 The purpose of the connecting cylinder 2 on the lower end face of the base 1 is to facilitate connection with support legs 21 of various heights. The pressing column 221 moves in the elongated groove 22 to facilitate adjustment of the height of each support leg 21. The connecting part is designed so that when the support leg 21 is disassembled, it can be rotated after releasing the engagement between the pressing column 221 and the elongated groove 22. The operation is convenient. After the support leg 21 is installed, the pressing column 221 enters the elongated groove 22. At this time, the connecting part plays a limiting and locking role on the support leg 21, thereby installing the support leg 21 in the connecting cylinder 2. This achieves the purpose of facilitating the installation of support legs 21 of different heights onto the base 1 of the potter's wheel according to the requirements.

[0050] like Figure 3 and Figure 4 and Figure 5 and Figure 6The connector includes several limiting strips 222 arranged circumferentially on the inner wall of the connecting cylinder 2. Each limiting strip 222 is distributed along the length of the connecting cylinder 2. The upper end of the support leg 21 is circumferentially provided with an arc-shaped groove 23 for the corresponding limiting strip 222 to be inserted. The bottom of the arc-shaped groove 23 is fixedly embedded with a long strip plate 231 on one side of the limiting strip 222. The long strip plate 231 is located on one side of the limiting strip 222 and is in contact with one side of the limiting strip 222. At this time, the pressing column 221 is staggered with the long strip groove 22. Both the long strip plate 231 and the limiting strip 222 are provided with several support plates 232 spaced apart along the length of the long strip plate 231 or the limiting strip 222. The support plates 232 on the long strip plate 231 correspond to the support plates 232 on the limiting strip 222. The space between two adjacent support plates 232, and the side of each of the opposing support plates 232 is set as an arc surface, is designed so that when the support leg 21 is rotated, the support plate 232 on the elongated plate 231 can easily enter between two adjacent support plates 232 on the limiting plate 222, thereby forming a stable supporting force between each support plate 232. At this time, the pressing column 221 enters the elongated groove 22, thereby restricting the rotation of the support leg 21. When it is necessary to adjust the position of each support leg 21 entering the connecting cylinder 2, it is only necessary to change the height position of the pressing column 221 in the elongated groove 22. At this time, the support leg 21 provides supporting force to the connecting cylinder 2 through each support plate 232, so that the position of the connecting cylinder 2 is stable, thereby stabilizing the position of the base 1.

[0051] like Figure 3 and Figure 4 and Figure 5 and Figure 6 The telescopic component includes a telescopic groove 24 formed on the outer wall of the support leg 21. The telescopic groove 24 is distributed in the horizontal direction. One end of the pressing column 221 is slidably connected in the telescopic groove 24. A compression spring 241 is provided at the bottom of the telescopic groove 24. The end of the compression spring 241 away from the bottom of the telescopic groove 24 is fixed on the pressing column 221. When the compression spring 241 is in its natural state, the pressing column 221 is located in the elongated groove 22, and the end of the pressing column 221 extending out of the elongated groove 22 is spherical.

[0052] like Figure 3 and Figure 4 and Figure 5 and Figure 6When people need to sit while throwing the pottery, the support leg 21 is a short leg, and at this time the support leg 21 is a vertically distributed rod. Alternatively, when people need to stand while throwing the pottery, the support leg 21 is a long leg, and the support leg 21 has a vertically distributed rod at the top, a rod that extends obliquely away from the machine base 1 in the middle, and another vertically distributed rod at the bottom. At this time, the part of the support leg 21 with the obliquely extended rod is to provide stable support for the machine base 1. When the pressing column 221 enters the elongated groove 22, the obliquely extended rod of the support leg 21 is exactly located in the direction that extends obliquely away from the machine base 1. That is, the part of the support leg 21 that extends obliquely away from the machine base 1 is exactly in the predetermined position. At this time, it is convenient for people to determine the rotation position of the support leg 21 based on its position.

[0053] Working principle:

[0054] Step 1: When it is necessary to install the outrigger 21, first press the pressing column 221 into the telescopic groove 24. At this time, slide the upper end of the outrigger 21 into the connecting cylinder 2. The outer wall of the outrigger 21 fits against the inner wall of the connecting cylinder 2. The limiting strip 222 on the connecting cylinder 2 also enters the arc groove 23 and is located on one side of the long strip plate 231. At this time, the pressing column 221 and the long strip groove 22 are misaligned.

[0055] Step 2: Rotate the support leg 21 so that the pressing column 221 is rotated into the long strip groove 22, and the support plate 232 on the long strip plate 231 is inserted between two adjacent support plates 232 on the limiting strip plate 222, thereby forming a stable supporting force between each support plate 232, and thus realizing the installation of the support leg 21.

[0056] Step 3: When disassembling the support leg 21, press the pressing column 221 into the telescopic groove 24, so that the compression spring 241 deforms and has elastic restoring force. Then rotate the support leg 21 so that the long strip plate 231 is located on one side of the limiting strip plate 222. The pressing column 221 and the long strip groove 22 are misaligned again. At this time, the support leg 21 can be pulled out of the connecting cylinder 2, which is convenient for disassembly.

[0057] Both semi-circular basins 12 include annular wall 121 and annular wall 122, which are coaxially distributed inside and outside. Both annular wall 121 and annular wall 122 are semi-circular. The diameter of annular wall 121 is smaller than the diameter of annular wall 122, and the height of the upper end of annular wall 121 is lower than the height of the upper end face of annular wall 122. The bottom of the outer wall of annular wall 121 and the bottom of the inner wall of annular wall 122 are connected by a semi-circular base plate 123. The height of the lower end of the outer wall of annular wall 122 is higher than the height of the base plate 123, that is, the lower end face of annular wall 122 is higher than the height of the base plate 123. The inner wall of annular wall 122 extends downward to connect with one side of the base plate 123.

[0058] like Figure 1 and Figure 7 One of the basins 12 has an annular wall 2 122 on one side relative to the annular wall 2 122 of the other basin 12, which is provided with a plug 124 that can be inserted into the other annular wall 2 122. Each basin 12 has only one plug 124. The lower end of the annular wall 2 122 is provided with a release member to release the connection between the plug 124 and the other annular wall 2 122.

[0059] like Figure 1 and Figure 7 When the two basins 12 are installed into a complete circular basin 12, the first annular wall 121 is located below the surface of the turntable 11. The purpose is to move the space for storing mud and water formed between the first annular wall 121, the second annular wall 122 and the bottom plate 123 to the bottom of the turntable 11, so that the mud and water can fall off the turntable 11. The height of the upper end of the second annular wall 122 is higher than the height of the surface of the turntable 11.

[0060] like Figure 1 and Figure 7 When the two basins 12 are installed into a complete circular basin 12, the first annular wall 121 is located below the surface of the turntable 11, so that the mud and water flowing from the turntable 11 flows onto the base plate 123 between the first annular wall 121 and the second annular wall 122. When the two basins 12 are installed into a complete circular basin 12, the corresponding inserts 124 of the two basins 12 are inserted into the other basin 12. When it is necessary to disassemble the two basins 12, the release mechanism can release the limit on the inserts 124. At this time, the two basins 12 can be moved in opposite directions. At this time, there is no need to pull out the inserts 124 by force during the disassembly process, which makes disassembly convenient and reduces the splashing of mud and water during the disassembly process.

[0061] like Figure 8 and Figure 9 and Figure 10 Both the lower end faces of the first annular wall 121 and the second annular wall 122 are provided with cavities 13, which extend out of the lower end faces of the first annular wall 121 and the second annular wall 122. The cavity 13 reduces the weight of the basin 12 on the one hand, and reduces the friction area between the lower end face of the basin 12 and the upper end face of the base 1 on the other hand. The cavity 13 on the second annular wall 122 also makes it easier for the user to pick up the basin 12.

[0062] like Figure 10 and Figure 11 and Figure 12 and Figure 13The release mechanism includes a rectangular frame 14 disposed in the cavity 13 of the second annular wall 122. One side of the rectangular frame 14 abuts against the inner wall of the second annular wall 122 near the other annular wall 122, and the upper end of the rectangular frame 14 is closed. A sliding plate 141 is connected to the rectangular frame 14 by sliding up and down. The upper end of the sliding plate 141 is provided with a compression spring 142 connected to the upper inner wall of the rectangular frame 14. The second annular wall 122 has a slot 143 on the side wall facing the other annular wall 122 that extends into the rectangular frame 14 and is used for inserting the plug 124. The sliding plate 141 has a placement groove 144 corresponding to the plug 124. The size of the placement groove 144 is larger than the size of the slot 143. A retaining plate 145 is provided on the upper wall of the placement groove 144. A retaining groove 146 is provided on the upper surface of the plug 124 for the retaining plate 145 to be inserted.

[0063] like Figure 10 and Figure 11 and Figure 12 and Figure 13 The lower end of the slide plate 141 extends out of the lower end of the outer wall of the annular wall 122, and there is a gap between the lower end of the slide plate 141 and the upper end face of the base 1, which facilitates the user's fingers to press the slide plate 141 upward.

[0064] like Figure 10 and Figure 11 and Figure 12 and Figure 13 The upper and lower ends of the insertion block 124 are provided with inclined surfaces 147. The setting of the two inclined surfaces 147 reduces the size of the end of the insertion block 124. The end of the insertion block 124 is distributed away from the basin 12 that fixes the insertion block 124. The lower end surface of the card plate 145 is provided with an inclined surface 148 that cooperates with the inclined surface 147 at the upper end of the insertion block 124.

[0065] like Figure 10 and Figure 11 and Figure 12 and Figure 13 The working principle of the release mechanism is as follows: During the process of moving the two basins 12 towards each other to form a complete circle, the inserts 124 on each basin 12 are inserted into the corresponding slots 143. At this time, the inclined surface 147 on the upper end of the insert 124 presses the inclined surface 148, causing the locking plate 145 to move upward, which in turn drives the sliding plate 141 to move upward. The compression spring 142 is compressed. When the two basins 12 abut against each other on one side, the locking plate 145 corresponds to the locking groove 146, and the sliding plate 141 moves downward under the action of the compression spring 142, which causes the locking plate 145 to be inserted into the locking groove 146, thus limiting the insertion of the insert 124 and making the connection between the two basins 12 stable. At this time, the lower end of the sliding plate 141 is still located at the lower end of the outer wall of the annular wall 122, and there is a gap between it and the upper end of the base 1.

[0066] like Figure 10 and Figure 11 and Figure 12 and Figure 13 When the connection between the two basins 12 is released, the person moves their finger to the lower end of the slide plate 141 and presses the slide plate 141 upward, causing the slide plate 141 to compress the spring 142 again, thereby causing the locking plate 145 to move out of the slot 146. Pushing one of the basins 12 away from the other basin 12 will cause the two inserts 124 to move out of the slot 143, thereby releasing the slide plate 141.

[0067] like Figure 10 and Figure 11 and Figure 12 and Figure 13 In the above process, each basin 12 has only one insert block 124 and one slot 143. Therefore, when disconnecting the connection between the two basins 12, the middle fingers of a person's two hands press upwards on the lower end of the sliding plate 141 of the two basins 12. Both palms are located on the outer wall of one of the annular walls 122, and the two thumbs are bent and located on the upper wall of the other annular wall 122. After pressing the sliding plate 141 to release the restriction on the insert block 124, the thumbs are straightened, and at the same time, the two palms are used to horizontally remove the annular wall 122 away from the other annular wall 122. This makes one of the two basins 12 stationary and the other horizontally and stably removed by the two hands, making the disassembly of the two basins more stable and further reducing the splashing of mud and water during the disassembly process.

[0068] like Figure 10 and Figure 11 and Figure 12 and Figure 13 The annular wall 122 below the slot 143 and the rectangular frame 14 below the slot 143 are both provided with elongated guide grooves 15 distributed in the vertical direction. The slide plate 141 is threaded with screws 151 that move up and down in the guide grooves 15. The guide grooves 15 are symmetrically distributed on both sides of the rectangular frame 14, that is, there are screws 151 on both sides of the slide plate 141. At this time, the nuts of the screws 151 on one side of the slide plate 141 move up and down in the guide grooves 15 of the annular wall 122, and the nuts of the screws 151 on the other side slide up and down in the guide grooves 15 of the rectangular frame 14. The upper end of the slide plate 141 is in contact with the lower end of the compression spring 142.

[0069] like Figure 10 and Figure 11 and Figure 12 and Figure 13The purpose of this design is to fix the slide plate 141 inside the rectangular frame 14 with screws 151, and to make the slide plate 141 abut against the compression spring 142, so as to facilitate the removal of the slide plate 141. The screws 151 can be unscrewed from the slide plate 141, so that the slide plate 141 falls out from the lower end of the rectangular frame 14. When the insert block 124 is not inserted into the slot 143, the screws 151 abut against the lower end of the guide groove 15.

[0070] The slide plate 141 has several threaded holes that are threaded to the screws 151, and the threaded holes are arranged along the height direction of the slide plate 141. The design of each threaded hole is such that the connection position between the screws 151 and the slide plate 141 can be changed after the elastic force of the compression spring 142 changes.

[0071] like Figure 10 and Figure 11 and Figure 12 and Figure 13 It also includes baffles 16 at both ends of the two basins 12. The two baffles 16 are connected to both ends of the bottom plate 123, so that each basin 12 is an independent water storage tank. The baffles 16 are connected to the inner walls of the first annular wall 121 and the second annular wall 122, respectively. Each baffle 16 of the basin 12 is provided with a rod 161 that can be inserted into the other baffle 16 of the opposite basin 12. The other baffle 16 has a hole 162 for inserting the rod 161. The two baffles 16 on each basin 12: one baffle 16 has a rod 161 and the other baffle 16 has a hole 162. The hole 162 on the baffle 16 communicates with the cavity 13 of the first annular wall 121 and is distributed near the slot 143. When the two basins 12 are closed, it is convenient for the rod 161 to enter the hole 162.

[0072] like Figure 10 and Figure 11 and Figure 12 and Figure 13 In addition, a sealing plate 19 extending toward another annular wall 122 is provided on the inner wall of one annular wall 122. The sealing plates 19 are distributed along the height direction of the inner wall of the annular wall 122. The lower end of each sealing plate 19 is provided with a sealing plate 291 extending to the upper end face of the annular wall 121. One end of the sealing plate 291 is also located on the lower end face of the turntable 11. The sealing plates 291 are horizontally distributed.

[0073] like Figure 1 and Figure 14 The annular wall 122 is equipped with a testing device to check whether the turntable 11 rotates smoothly. After the potter's wheel has been used for a long time or after initial installation, it is necessary to check whether the turntable 11 is stable. If the test is to be performed during use, the mud on the upper surface and side wall of the turntable 11 should be wiped off with a sponge first.

[0074] like Figure 1 and Figure 14 The testing component includes an inverted U-shaped fixing plate 17 inserted into the outer wall of the second annular wall 122. There are gaps between the two vertical walls of the fixing plate 17 and the inner and outer walls of the second annular wall 122. The fixing plate 17 has a wooden board 171 and a wooden cylinder 172 on one of the vertical walls inside the second annular wall 122. The wooden board 171 and the cylinder 172 are horizontally distributed and the wooden board 171 is located above the cylinder 172. The fixing plate 17 is provided with a driving component that drives the wooden board 171 and the cylinder 172 to move up and down or horizontally.

[0075] like Figure 1 and Figure 14 The driving component includes a screw 173 that passes through the horizontal wall of the fixed plate 17. The lower end of the screw 173 is screwed into the upper end face of the second annular wall 122 and enters the cavity 13 of the second annular wall 122. Locking blocks 174 are threadedly connected to both the upper and lower sides of the horizontal wall of the fixed plate 17. A limiting block 175 that abuts against the upper end face of the second annular wall 122 is threadedly connected to the outer wall of the screw 173.

[0076] like Figure 1 and Figure 14 The horizontal wall of the fixing plate 17 is provided with a long strip-shaped adjustment groove 176 for the screw 173 to slide horizontally. When the screw 173 moves in the adjustment groove 176, the fixing plate 17 moves in a direction closer to or away from the turntable 11.

[0077] like Figure 1 and Figure 14 Working principle of the test piece: When it is necessary to test whether the turntable 11 is stable, first screw 173 is screwed into the upper end face of the second annular wall 122, so that the wooden board 171 and the cylinder 172 gradually descend in the second annular wall 122 until the lower end face of the wooden board 171 touches the upper end face of the turntable 11. At this time, stop screwing 173 and rotate the locking block 174 located at the upper end of the fixed plate 17, so that the locking block 174 above the fixed plate 17 fixes the fixed plate 17 between the upper and lower locking blocks 174. At this time, there is a gap between the end of the cylinder 172 and the side wall of the turntable 11.

[0078] like Figure 1 and Figure 14 Then, rotate the limiting block 175 so that it abuts against the upper end face of the annular wall 122, thereby restricting the position of the screw 173. Rotate the turntable 11 so that the surface of the turntable 11 rubs against the lower end face of the wooden board 171, thereby producing sound. When the sound is high or low or intermittent, it indicates that the turntable 11 is uneven; when the sound is continuous and of a certain volume, it indicates that the turntable 11 is stable.

[0079] like Figure 1and Figure 14 Then, rotate the locking block 174 above the fixing plate 17 to create a gap between the locking block 174 and the fixing plate 17, facilitating the movement of the fixing plate 17. Loosen the limiting block 175 and rotate the screw 173 in the opposite direction, causing the wooden board 171 to move upward and create a gap between it and the surface of the turntable 11. Then, push the fixing plate 17 towards the turntable 11, causing the screw 173 to move within the adjusting groove 176 until one end of the cylinder 172 abuts against the side wall of the turntable 11. Then rotate... Tighten the locking block 174 above the fixed plate 17 to fix the fixed plate 17 between the upper and lower locking blocks 174. Then rotate the limiting block 175 until it contacts the upper end face of the annular wall 122. Rotate the turntable 11 so that the side wall of the turntable 11 rubs against the end face of the cylinder 172, thereby producing a sound. When the sound is high or low or intermittent, it indicates that the turntable 11 is uneven; when the sound is continuous and of a certain volume, it indicates that the turntable 11 is stable.

[0080] like Figure 1 The base 1 has several elongated mounting slots 18 on both sides of the basin 12, which run through the upper and lower edges of the base 1. The base 1 is fitted with a water box 181 through the mounting slots 18. The opening of the water box 181 faces upward. One side wall of the water box 181 is provided with a plate 182 that can be inserted into the mounting slot 18. This makes it easy to remove the water box 181 after the basin 12 is removed. The mounting slots 18 are located at the lower end of the annular wall 122, which reduces the gap between the water box 181 and the basin 12 and reduces the occurrence of water falling from the operator's hands onto the base 1 during the use of the potter's wheel.

[0081] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
