Description

Technical Field

[0001] This invention relates to the field of wooden dining table technology, specifically a wooden dining table with a mortise and tenon joint structure. Background Technology

[0002] The original meaning of a dining table refers to a table specifically used for eating. Based on materials, they can be categorized as solid wood dining tables, steel and wood dining tables, marble dining tables, marble dining tables, marble coffee tables, jade dining tables, jade dining tables, jade coffee tables, and marble dining tables, etc.

[0003] According to the patent application published on the Internet (authorization announcement number: CN 212852882 U), a wooden oil-resistant dining table is described as follows: "A wooden oil-resistant dining table includes a dining table body, a base body fixedly attached to the bottom of the dining table body, a lifting plate inside the base body, several moving rods fixedly attached to the bottom of the lifting plate, universal wheels installed at the bottom of each moving rod, a telescopic spring fixedly attached to the top of the lifting plate, a protective mechanism sleeved on the telescopic spring, the top of the telescopic spring fixed to the top of the base body, a buckle hinged to one side of the base body, a push rod hinged to the upper part of the buckle, and a bending spring sheet fixedly connected to the upper part of the buckle. Beneficial effects: The high-temperature resistant layer prevents the dining table body from deforming when exposed to high temperatures, increasing the service life of the dining table body; the waterproof layer effectively prevents the dining table surface from getting damp and susceptible to insect infestation, and the surface of the waterproof layer is smooth, making it easy to wipe away water stains and oil stains; the wear-resistant layer improves the wear resistance of the dining table body surface."

[0004] Based on the above, the inventor believes that the following defects exist: This wooden oil-resistant dining table has a smooth surface that is easy to wipe clean, is resistant to insects and pests, and is not prone to cracks or fissures. It also has good load-bearing capacity. However, because the size of the table is fixed, it will undoubtedly increase the space occupied by the table when it needs to be transported, making it inconvenient to disassemble and transport. When it needs to be assembled, it cannot achieve good assembly efficiency, thus reducing the practicality of the device. Therefore, it is necessary to design a wooden dining table with a mortise and tenon structure that is practical and easy to assemble. Summary of the Invention

[0005] The purpose of this invention is to provide a wooden dining table with a mortise and tenon structure to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a wooden dining table with a mortise and tenon structure, including table legs, a reinforcing mechanism at the top of the table legs, a support at the top of the reinforcing mechanism, a screw inside the support, four supports, a first tabletop and a second tabletop respectively at the top of the four supports, a riveting mechanism at the bottom of the first tabletop, and a rotating mechanism at the top of both the first and second tabletops. The riveting mechanism includes a connecting groove, which is located on the right side of the first table. A connecting block is inserted into the connecting groove. A limiting seat is fixedly connected to the bottom of the second table and the first table. A long block is inserted into the limiting seat. An insert block is fixedly connected to the outside of the long block. A short shaft and a long shaft are fixedly connected to the top of the long block, respectively. A bolt is provided on one side of the limiting seat.

[0007] According to the above technical solution, both the bottom of the first tabletop and the bottom of the connecting block are provided with arc-shaped holes. The short shaft is inserted into the inner wall of the arc-shaped hole. Thus, through the cooperation between the short shaft and the arc-shaped hole, the short shaft can limit the connecting block, making it impossible for the connecting block to be easily pulled out of the connecting groove.

[0008] According to the above technical solution, the limiting seat and the bottom of the first table are both provided with insertion holes that match the long shaft. The long shaft is inserted into the inner wall of the insertion hole, so that the long shaft can be further enhanced by the mutual cooperation between the insertion hole and the long shaft, thereby achieving the purpose of riveting.

[0009] According to the above technical solution, a torsion block is fixedly connected to one end of the bolt, and threaded holes matching the bolt are opened on one side of the long shaft and the insert block. The bolt is threadedly connected to the inner wall of the threaded hole. Thus, through the mutual cooperation of the bolt and the threaded hole, the insert block cannot be pulled out from the inside of the limiting seat, thereby realizing the splicing and installation of the first table and the second table. Furthermore, the torsion block can further improve the convenience of operation.

[0010] According to the above technical solution, the reinforcement mechanism includes a threaded head, which is fixedly connected to the bottom of the support. A threaded sleeve is threadedly connected to the outer wall of the threaded head. A fixed cylinder is fixedly connected to the bottom of both the first and second tabletops. A spring is fixedly connected to the top of the inner wall of the fixed cylinder. A circular plate is fixedly connected to the end of the spring away from the inner wall of the fixed cylinder. A push block is fixedly connected to the outer side of the circular plate. A connecting shaft is fixedly connected to the bottom of the circular plate. A limit plate is rotatably connected to the outer wall of the connecting shaft. A baffle is fixedly connected to the outer wall of the threaded sleeve. Through the mutual cooperation of the limit plate and the baffle, the stability of the connection between the threaded sleeve and the threaded head can be further enhanced, achieving good stability while realizing the connection and installation.

[0011] According to the above technical solution, the threaded sleeve is fixedly connected to the top of the table leg. The bottom of the support, the first table board and the second table board are all provided with limiting holes that match the screw. The screw is threadedly connected to the inner wall of the limiting hole. Thus, through the mutual cooperation of the screw and the limiting hole, the connection between the support and the first table board and the second table board can be further enhanced, making it easier for the staff to operate and use the equipment.

[0012] According to the above technical solution, the circular plate is slidably connected to the inner wall of the fixed cylinder, and a movable port matching the push block is opened on the outer side of the fixed cylinder. The push block passes through the movable port, which allows the operator to push the push block so that the push block drives the circular plate to move stably through the movable port, thereby compressing the spring.

[0013] According to the above technical solution, the bottom of the fixed cylinder is provided with a sliding hole that matches the connecting shaft. The connecting shaft passes through the bottom of the fixed cylinder through the sliding hole, so that the circular plate can drive the connecting shaft to move through the sliding hole during the movement. Thus, under the elastic action of the spring, pressure can be applied to the connecting shaft to further achieve the reinforcement effect.

[0014] According to the above technical solution, the baffle has a limiting port that matches the limiting plate. The connecting shaft passes through the limiting port. The top of the limiting plate contacts the bottom of the baffle. The size of the limiting plate is smaller than the size of the limiting port. The limiting plate and the misalignment port are misaligned, thereby limiting the limiting plate and preventing it from being pulled back by the elasticity of the spring.

[0015] According to the above technical solution, the rotating mechanism includes a limiting shaft, a fixing block inserted into the outer wall of the limiting shaft, a support frame fixedly connected to one side of the fixing block, a motor fixedly connected to the bottom of the inner wall of the support frame, a small gear on the top of the motor, a large gear meshing with the outer wall of the small gear, a support column fixedly connected to the inner ring of the large gear, a disc fixedly connected to the top of the support column, a rotating hole matching the support column on the top of the support frame, the support column rotatably connected to the inner wall of the rotating hole, an output shaft fixedly connected to the output end of the motor, and a small gear fixedly connected to the outer wall of the output shaft. By starting the motor, the disc can be rotated stably, allowing staff to use the dining table flexibly.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. This invention, by setting up a riveting mechanism, inserts corresponding connecting blocks into the inner wall of corresponding connecting grooves to achieve initial limiting and supporting connection of the first and second tabletops. Then, a long block inserts corresponding inserts into the interior of corresponding limiting seats, so that both the inserts and the long shaft are inserted into the corresponding arc-shaped holes and insertion holes. Under the action of the short and long shafts, the limiting seats are limited, achieving initial splicing limitation of the first and second tabletops. Next, a twisting block at one end of the bolt screws the corresponding bolt into the interior of the corresponding limiting seat and insert, preventing the insert from detaching from the limiting seat and limiting its position. The long block also does not easily move, achieving the splicing and installation of the first and second tabletops. This invention achieves good operational efficiency during splicing, disassembly, or installation, further enhancing the ease of operation of the device, and reducing the space occupied by the dining table during transportation, thus reducing transportation costs.

[0017] 2. This invention, by providing a reinforcing mechanism, pushes the push block downwards, causing the circular plate to move downwards. Simultaneously, the push block can slide on the inner wall of the fixed cylinder, and the circular plate will also stretch the spring. During the downward movement of the circular plate, it will also drive the limiting plate through the baffle via the connecting shaft. Then, by rotating the limiting plate, the limiting plate can be misaligned with the limiting opening of the baffle, thereby limiting the limiting plate and preventing it from being pulled by the stretched spring. Thus, through the mutual cooperation of the baffle and the limiting plate, the connection between the threaded sleeve and the threaded head can be processed, reducing the possibility of the threaded sleeve loosening, thereby further enhancing the stability of the device and facilitating operation by the staff.

[0018] 3. This invention, by setting a rotating mechanism, inserts a fixing block into the outer wall of the limiting shaft, thereby supporting and limiting the support frame and preventing it from easily shaking. Then, during use, when the disc needs to be rotated, the motor is first started, so that the output shaft of the motor can drive the small gear to rotate. The small gear drives the support column to rotate through the large gear, which in turn drives the support column to rotate the disc, thus realizing the rotation of the disc. This makes it easier for users to use the dining table and also enhances the flexibility of the device to a certain extent. Attached Figure Description

[0021] 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.

[0022] This invention provides the following technical solutions: Example 1

[0023] Combination Figures 1 to 7 A wooden dining table with a mortise and tenon structure includes table legs 1, a reinforcing mechanism 3 at the top of the table legs 1, a support 5 at the top of the reinforcing mechanism 3, screws 6 inside the support 5, four supports 5, a first table board 7 and a second table board 8 respectively at the top of the four supports 5, a riveting mechanism 2 at the bottom of the first table board 7, and a rotating mechanism 4 at the top of both the first table board 7 and the second table board 8. The riveting mechanism 2 includes a connecting groove 21, which is located on the right side of the first table 7. A connecting block 22 is inserted into the connecting groove 21. A limiting seat 23 is fixedly connected to the bottom of the second table 8 and the first table 7. A long block 24 is inserted into the limiting seat 23. An insert block 25 is fixedly connected to the outside of the long block 24. A short shaft 27 and a long shaft 26 are fixedly connected to the top of the long block 24 respectively. A bolt 28 is provided on one side of the limiting seat 23.

[0024] Furthermore, both the bottom of the first tabletop 7 and the bottom of the connecting block 22 are provided with arc-shaped holes. The short shaft 27 is inserted into the inner wall of the arc-shaped hole. Through the cooperation between the short shaft 27 and the arc-shaped hole, the short shaft 27 can limit the connecting block 22, making it difficult for the connecting block 22 to be easily pulled out of the connecting groove 21.

[0025] Furthermore, the interior of the limiting seat 23 and the bottom of the first table 7 are provided with insertion holes that match the long shaft 26. The long shaft 26 is inserted into the inner wall of the insertion hole, so that the long shaft 26 can be further enhanced by the mutual cooperation between the insertion hole and the long shaft 26, thereby achieving the purpose of riveting.

[0026] Furthermore, a torsion block is fixedly connected to one end of the bolt 28, and threaded holes matching the bolt 28 are opened on one side of the long shaft 26 and the insert 25. The bolt 28 is threadedly connected to the inner wall of the threaded hole. Thus, through the mutual cooperation between the bolt 28 and the threaded hole, the insert 25 cannot be pulled out from the inside of the limit seat 23, realizing the splicing and installation of the first table 7 and the second table 8. The torsion block can further improve the convenience of operation. Example 2

[0027] See Figures 1 to 7 Furthermore, based on Embodiment 1, the reinforcement mechanism 3 includes a threaded head 31, which is fixedly connected to the bottom of the support 5. A threaded sleeve 32 is threadedly connected to the outer wall of the threaded head 31. A fixed cylinder 33 is fixedly connected to the bottom of both the first table plate 7 and the second table plate 8. A spring 34 is fixedly connected to the top of the inner wall of the fixed cylinder 33. A circular plate 35 is fixedly connected to the end of the spring 34 away from the inner wall of the fixed cylinder 33. A push block 36 is fixedly connected to the outer side of the circular plate 35. A connecting shaft 37 is fixedly connected to the bottom of the circular plate 35. A limiting plate 38 is rotatably connected to the outer wall of the connecting shaft 37. A baffle 39 is fixedly connected to the outer wall of the threaded sleeve 32. Through the mutual cooperation of the limiting plate 38 and the baffle 39, the stability of the connection between the threaded sleeve 32 and the threaded head 31 can be further enhanced, achieving good stability while realizing the connection and installation.

[0028] Furthermore, the threaded sleeve 32 is fixedly connected to the top of the table leg 1. The bottom of the support 5, the first table plate 7, and the second table plate 8 are all provided with limiting holes that match the screw 6. The screw 6 is threaded into the inner wall of the limiting hole. Thus, through the mutual cooperation of the screw 6 and the limiting hole, the connection between the support 5 and the first table plate 7 and the second table plate 8 can be further enhanced, making it easier for the staff to operate and use the equipment.

[0029] Furthermore, the circular plate 35 is slidably connected to the inner wall of the fixed cylinder 33. The outer side of the fixed cylinder 33 is provided with a moving port that matches the push block 36. The push block 36 passes through the moving port, which allows the staff to push the push block 36 so that the push block 36 can drive the circular plate 35 to move stably through the moving port, thereby compressing the spring 34.

[0030] Furthermore, the bottom of the fixed cylinder 33 is provided with a sliding hole that matches the connecting shaft 37. The connecting shaft 37 passes through the bottom of the fixed cylinder 33 through the sliding hole, so that the circular plate 35 can drive the connecting shaft 37 to move through the sliding hole during the movement. Thus, under the elastic action of the spring 34, pressure can be applied to the connecting shaft 37 to further achieve the reinforcement effect.

[0031] Furthermore, the baffle 39 has a limiting port that matches the limiting plate 38. The connecting shaft 37 passes through the limiting port. The top of the limiting plate 38 contacts the bottom of the baffle 39. The size of the limiting plate 38 is smaller than the size of the limiting port. The limiting plate 38 is misaligned with the misalignment port, thereby limiting the limiting plate 38 and preventing it from being pulled back by the elastic action of the spring 34. Example 3

[0032] See Figures 1 to 7 Based on Embodiments 1 and 2, the rotating mechanism 4 further includes a limiting shaft 48, a fixing block 46 inserted into the outer wall of the limiting shaft 48, a support frame 41 fixedly connected to one side of the fixing block 46, a motor 42 fixedly connected to the bottom of the inner wall of the support frame 41, a small gear 43 provided on the top of the motor 42, a large gear 44 meshing with the outer wall of the small gear 43, a support column 45 fixedly connected to the inner ring of the large gear 44, a disc 47 fixedly connected to the top of the support column 45, a rotating hole matching the support column 45 opened on the top of the support frame 41, the support column 45 rotatably connected to the inner wall of the opened rotating hole, an output shaft fixedly connected to the output end of the motor 42, and the small gear 43 fixedly connected to the outer wall of the output shaft. By starting the motor 42, the disc 47 can be rotated stably, making it convenient for staff to use the dining table flexibly.

[0033] In actual operation, when this device is used and the dining table needs to be assembled, the worker first installs the four supports 5 at the bottom of the first tabletop 7 and the second tabletop 8 respectively using screws 6. Then, the threaded sleeve 32 is screwed into the outer wall of the threaded head 31 through the table legs 1, thus achieving initial positioning of the table legs 1. Next, the push block 36 is pushed downwards, causing the push block 36 to move the circular plate 35 downwards. Simultaneously, it can slide on the inner wall of the fixed cylinder 33. The circular plate 35 also stretches the spring 34, and during the downward movement of the circular plate 35... The connecting shaft 37 drives the limiting plate 38 through the baffle 39. Then, by rotating the limiting plate 38, the limiting plate 38 can be misaligned with the limiting opening of the baffle 39, thereby limiting the limiting plate 38 and preventing it from being pulled by the spring 34 in the stretched state. Through the cooperation of the baffle 39 and the limiting plate 38, the connection between the threaded sleeve 32 and the threaded head 31 can be processed, reducing the possibility of the threaded sleeve 32 loosening, thereby further enhancing the stability of the device and making it easier for operators to use. After the table legs 1 are installed and positioned, the corresponding connecting blocks 22 are inserted into the inner wall of the corresponding connecting grooves 21 via the second tabletop 8, achieving initial positioning and support for the first tabletop 7 and the second tabletop 8. Next, the corresponding insert blocks 25 are inserted into the corresponding limiting seats 23 via the long block 24. Thus, both the insert blocks 25 and the long shaft 26 are inserted into the corresponding arc-shaped holes and insertion holes. Under the action of the short shaft 27 and the long shaft 26, the limiting seats 23 are positioned, achieving the initial assembly of the first tabletop 7 and the second tabletop 8. After the limit is reached, the corresponding bolt 28 is screwed into the corresponding limit seat 23 and the insert 25 through the twisting block at one end of the bolt 28. This prevents the insert 25 from coming out of the limit seat 23, thus limiting the insert 25. The long block 24 will also not move easily, realizing the splicing and installation of the first table 7 and the second table 8. Good operation efficiency can be achieved during the splicing, disassembly or installation process, further enhancing the ease of operation of the device, and reducing the space occupied by the dining table during transportation, thus reducing transportation costs. After the dining table assembly and positioning are completed, the fixing block 46 can be inserted into the outer wall of the limiting shaft 48 through the support frame 41, thereby supporting and limiting the support frame 41 and preventing it from easily shaking. Then, during use, when it is necessary to rotate the disc 47, the motor 42 is started first, so that the output shaft of the motor 42 can drive the pinion 43 to rotate. The pinion 43 drives the support column 45 to rotate through the large gear 44, which in turn drives the support column 45 to rotate the disc 47, thus realizing the rotation of the disc 47. This makes it easier for users to use the dining table and also enhances the flexibility of the device to a certain extent.
