Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of plate tension structure and plate. BACKGROUND

[0002] In today's furniture manufacturing and installation field, the connection mode between plates has been the key factor affecting product quality, use convenience and post-maintenance. With the improvement of people's living standards, the demand for furniture is no longer limited to basic use function, and more and more attention is paid to its flexibility, variability and environmental protection and other characteristics.

[0003] In traditional furniture installation, when connecting two plates, the most common method is tenon-mortise structure and screw fixed connection. As a long-standing technique, tenon-mortise structure can make the plate connection stable and bear certain external force with its ingenious concave-convex cooperation, and has a glorious history in the field of traditional Chinese furniture production. However, under the modern fast-paced life and consumption mode, its disadvantages gradually appear. Once the tenon-mortise connection is completed, the components are tightly engaged, and professional tools and exquisite skills are needed for disassembly. Otherwise, the plate may be damaged, causing damage to the overall structure of the furniture, making it difficult to realize non-destructive disassembly. This not only increases the difficulty of furniture repair, reconstruction or relocation, but also may cause material waste due to improper disassembly, which is contrary to the current concept of sustainable development.

[0004] Screw fixed connection is also widely used in various furniture assembly scenes. It is relatively easy to operate and has low cost. With a screwdriver, the plates can be quickly fixed together, and it is popular in economic furniture with mass production. However, problems arise over time. On the one hand, screws are prone to rust and looseness in humid environments or under long-term stress, affecting the structural stability of furniture and posing a safety hazard to users. On the other hand, when disassembling the plates connected by screws, due to the friction between the threads and the plates and the possible deformation of the screws, a lot of effort is often needed, and the screws may even be broken, making the disassembly process extremely difficult. Subsequent cleaning of residual screws is also very troublesome, which is also not conducive to the secondary use and modification of furniture.

[0005] In summary, the two existing mainstream plate connection methods have obvious shortcomings in meeting the current consumer demand for convenient disassembly, repeated use and environmental protection of furniture, and there is an urgent need for a new plate connection solution to fill this technical gap and adapt to the development trend of the furniture industry.

DETAILED DESCRIPTION

[0026] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model, obviously, the described embodiments are only some 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.

[0027] The following references Figures 1-4 The utility model is described as follows:

[0028] The embodiment is a plate tensioning structure, which comprises a first mounting part 1 and a second mounting part 2.

[0029] A connecting column 3 extends radially on the first mounting part 1, and the cross section of the connecting column 3 is square. The square cross section has multiple meanings. On the one hand, compared with the circular cross section, the square can effectively avoid self-rotation when embedded in the matching connecting groove, ensuring the accuracy and stability of the connection. On the other hand, during the subsequent tension process, the corners of the square can better disperse stress and prevent the structure from being damaged due to excessive local stress.

[0030] A threaded hole 4 is arranged on the connecting column 3 along the length direction of the connecting column 3, which provides accurate guidance for the rotation of the fastening bolt 6 and ensures that the tension can be stably applied along the axial direction of the connecting column 3, so that the whole tensioning process is controllable and efficient.

[0031] The second mounting part 2 is a circular ring, and the second mounting part 2 is provided with a slot opening 5. This ring-shaped design can not only surround a certain area to increase the contact area with the plate and improve the connection stability, but also can leave space for the operation of other components inside.

[0032] The slot opening 5 provides a necessary channel for the installation and operation of the fastening bolt 6. When assembling, the fastening bolt 6 can be smoothly positioned through the slot opening 5, and during the subsequent tensioning process, the inner side walls of the second mounting part 2 on both sides of the slot opening 5 form a slope 8 that abuts against the bolt head 7. This slope design is very ingenious. The role of the slope 8 is that when tightening the fastening bolt 6, as the bolt head 7 advances forward, due to the guiding effect of the slope, the bolt head 7 will exert a diagonal component force on the slope 8. This component force will cause the second mounting part 2 to move towards the first mounting part 1, thereby realizing the opposite tensioning action of the two mounting parts and further driving the plate connected thereto to closely fit.

[0033] The plate tensioning structure further comprises a fastening bolt 6 connected with the threaded hole 4, and the bolt head 7 of the fastening bolt 6 is located on the inner side of the second mounting part 2. The inner side walls of the second mounting part 2 on both sides of the slot opening 5 form a slope 8 that abuts against the bolt head 7.

[0034] During the screwing operation, the fastening bolt 6 is supported by the threaded hole 4, and gradually penetrates into the thread to generate an axial tension force, which is transmitted to the first mounting part 1 through the connecting column 3, and at the same time, the second mounting part 2 is pushed by the reaction force of the inclined surface 8, so as to finally realize the effect of pulling the first mounting part 1 and the second mounting part 2 towards each other, and complete the fixed connection of the plate. Moreover, when disassembly is needed, only the fastening bolt 6 needs to be unscrewed in the reverse direction, and since there is no complex jamming structure between the components, the first mounting part 1 and the second mounting part 2 can be easily taken out, the whole process is convenient to operate, without the need for special tools or professional skills, greatly improving the efficiency of plate connection and disassembly.

[0035] A plate is composed of a plate body 21 and a plate body 22, and the side surfaces of the plate body 21 and the plate body 22 are connected in close contact, and further comprising the plate tensioning structure described above, and the plate body 21 and the plate body 22 are respectively provided with mounting grooves 23, and the shapes and sizes of these mounting grooves 23 are accurately matched with the first mounting part 1 and the second mounting part 2 in the plate tensioning structure described above, forming a close embedded fitting relationship. When assembling, the first mounting part 1 and the second mounting part 2 can be embedded in the mounting grooves 23 of the corresponding plate body with a perfect fit, not only ensuring the stability of the connection and preventing displacement of the components during use, but also making the tensioning structure and the plate body appear to be integrated from the appearance, improving the overall aesthetic appearance.

[0036] The plate body 21 and the plate body 22 are respectively provided with connecting grooves 24, which play a key role in conduction and connection. One end of the connecting groove 24 is in communication with the corresponding mounting groove 23, ensuring that the tensioning force introduced from the mounting groove 23 can be smoothly transmitted to the area where the connecting groove 24 is located; the other end of the connecting groove 24 penetrates through the close surface of the plate body 21 or the plate body 22, which makes the connecting column 3 pass through smoothly during installation, realizes the butt joint with the other plate body, and thus completes the construction of the whole tensioning system. The existence of the connecting groove 24 is like building an invisible "bridge" inside the plate body, connecting various key components in series, ensuring the effective transmission of tension, and making the plate splicing more stable and reliable.

[0037] The first mounting part 1 is provided with two threaded holes 9 penetrating through the axial sides thereof, and a positioning pin 10 is threadedly connected in the threaded hole 9. This design provides a clever breakthrough point for further reinforcing the connection of the plate. The positioning pin 10 is threadedly connected in the threaded hole 9. When the first mounting part 1 and the second mounting part 2 are pulled and fixed according to the predetermined process, the positioning pin 10 is tightened as a key operation. With the rotation of the positioning pin 10, it drills into the plate body, and by utilizing the friction with the plate body material and the embedded depth thereof, the fixed connection degree between the first mounting part 1 and the plate body is greatly enhanced. This secondary reinforcement mechanism effectively deals with the potential connection loosening problem in long-term use or under a large external force impact, and guarantees the stability and reliability of the plate splicing structure. The positioning pin 10 is specially provided with an operation hole 12, which is intended to provide a convenient force point for a wrench or the like tool. The operator only needs to accurately insert the wrench into the operation hole 12, and can easily control the rotation of the positioning pin 10 to achieve accurate reinforcement operation, which not only improves the work efficiency, but also ensures the standardization of the operation.

[0038] The bolt head 7 is cylindrical, and is provided with operation holes 11 radially and cleverly, and not single, but multiple operation holes 11 are distributed in the circumferential direction of the bolt head 7. This layout fully considers the convenience and flexibility requirements in actual operation. When a cylindrical wrench is used to tighten the fastening bolt 6, the wrench is inserted into one of the operation holes 11 to drive the rotation of the bolt head 7. Since there are multiple operation holes 11, as the bolt head 7 rotates, the originally blocked operation holes 11 will be exposed one by one, which facilitates the operator to insert the wrench into the exposed operation hole 11, and can be smoothly and continuously operated, greatly speeding up the tightening or loosening of the fastening bolt 6, reducing the operation time, especially in batch assembly of plates, which can significantly improve the work efficiency.

[0039] The end surface of the bolt head 7 is provided with a positioning groove 13 penetrating through both sides thereof in the radial direction, the positioning groove 13 is provided with multiple positioning grooves 13 and is arranged in the circumferential direction of the bolt head 7, the inner side wall of the second mounting part 2 is provided with a positioning groove 14 corresponding to the positioning groove 13, and a torsion positioning piece 15 is inserted into the positioning groove 13 and the positioning groove 14. It is precisely inserted into the positioning groove 13 and the positioning groove 14 to form the first line of defense. Then, the fastening bolt 6 is further driven to rotate by a certain angle, and in this process, the torsion positioning piece 15 will be twisted and deformed due to the limitation of the two ends of the positioning groove. This deformation makes the torsion positioning piece 15 not only difficult to come out of the positioning groove, but also resists the loosening rotation of the fastening bolt 6 by virtue of the rigidity after the torsion, which provides double insurance for the connection state of the fastening bolt 6, and effectively guarantees the stability and reliability of the plate connection in a complex stress environment.

[0040] The torsion positioning sheet 15 is provided with a deformation groove 16. This is to optimize its torsion deformation characteristics. When the tightening bolt 6 is rotated to cause the torsion positioning sheet 15 to deform, the deformation groove 16 provides reasonable space for the deformation of the material, reasonably distributes the stress concentration area, avoids the premature rupture of the torsion positioning sheet 15 due to excessive local stress, ensures that it can effectively play a locking function, and prolongs the service life of the entire locking mechanism.

[0041] The torsion positioning sheet 15 is made of metal material. The metal material has good strength and toughness, can withstand a certain extrusion deformation when initially inserted into the positioning groove, ensures close fitting, can exhibit sufficient deformation resistance in subsequent torsion operation, maintains a stable shape after torsion, blocks the loosening of the tightening bolt 6, and is an ideal material for realizing the above locking function.

[0042] The width of the slotted opening 5 is equal to the diameter of the tightening bolt 6. This detail design is very important. On the one hand, at the initial assembly stage, it can ensure that the tightening bolt 6 smoothly passes through the slotted opening 5 into the predetermined position, avoid the bolt jamming due to the slotted opening 5 being too narrow, and affect the installation progress; on the other hand, after the tightening bolt 6 is installed in place and tightened, since the slotted opening 5 closely fits the bolt, it effectively limits the lateral displacement of the tightening bolt 6, prevents it from shaking, shifting and other unstable phenomena during the stress process, and further strengthens the stability and reliability of the entire plate tensioning structure.

[0043] The above only describes the preferred embodiments of the present application, and does not limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
