Description

Technical Field

[0001] This utility model relates to the field of furniture technology, and in particular to a retractable skirting board tenon and mortise splicing structure. Background Technology

[0002] Baseboard is a specific term used in interior decoration. As the name suggests, baseboard refers to the wall area that can be kicked. A Chinese utility model patent, authorized publication number "CN221031196U", discloses a modular baseboard that can prevent jamming, relating to the field of modular baseboard technology. It includes a baseboard board and a corner plate. Both the baseboard board and the corner plate have a slot at one end, and a retractable locking plate that mates with the slot at the other end, allowing for detachable installation. Both ends of the locking plate have a first bevel, and the inner edge of the first bevel has a second bevel. The edge connecting the first and second bevels protrudes outwards. The bottom of the second bevel has a locking groove, and a locking rod that movably engages with the locking groove is installed within the slot, locking the locking plate securely within the slot. Both the baseboard board and the corner plate have through grooves and recessed openings along the edges of the through grooves.

[0003] The above technical solution uses a first bevel at the outer end of the clamping plate to facilitate insertion into the slot, avoiding the problem of jamming caused by misalignment of the tenon and mortise structure. A locking rod is also used to reinforce the assembled skirting board. However, this technical solution still has certain drawbacks. For example, while the first bevel at the outer end of the clamping plate facilitates insertion, in actual operation, installers find it difficult to accurately control the alignment of the clamping plate and the slot. Jamming due to insertion angle deviation or positional offset is very likely, especially during large-area continuous installation or work at height. Due to limited operating space and poor visibility, the problem of inaccurate alignment between the clamping plate and the slot is even more pronounced, significantly reducing installation efficiency and potentially damaging the clamping plate or slot due to forced insertion, increasing maintenance costs. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a retractable skirting board tenon and mortise splicing structure. This structure can solve the problem that the device uses a first inclined surface at the outer end of the clamping plate to facilitate the insertion of the clamping plate into the clamping slot. However, in actual operation, it is difficult for installers to accurately control the alignment of the clamping plate and the clamping slot. This can easily lead to jamming due to deviation in insertion angle or position. This problem is particularly prominent when installing on a large area continuously or working at height. Due to limited operating space and poor visibility, the problem of the clamping plate and the clamping slot not being accurately aligned is even more prominent. This not only greatly reduces installation efficiency, but may also cause damage to the clamping plate or the clamping slot due to forced insertion, increasing maintenance costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a retractable skirting board tenon and mortise splicing structure, comprising two skirting board main bodies, each of which is provided with a positioning tenon assembly; The positioning tenon assembly includes a tenon and two first limiting blocks. The outer wall of the tenon has two first limiting block grooves. Each of the two first limiting block grooves is equipped with three first compression springs. The front outer wall of the two skirting board bodies has a tenon sliding groove. In this design, the outer wall of one end of the tenon is slidably connected to the interior of the corresponding tenon groove.

[0006] Preferably, the outer walls of the two first limiting blocks are slidably connected to the interior of the corresponding first limiting block grooves, and the six first compression springs are grouped in sets of three; The two ends of the two sets of first compression springs are fixedly connected to the outer wall of the corresponding first limiting block and the inside of the first limiting block groove, respectively.

[0007] Preferably, mortises are provided on the outer walls of the rear ends of both skirting board bodies, and three second compression springs are provided inside the two tenon grooves; Among them, the six second compression springs are grouped into three sets, and the two ends of the two sets of second compression springs are respectively fixedly connected to the outer wall of the corresponding tenon and the inner wall of the tenon groove.

[0008] Preferably, the outer wall of the tenon on the right-side skirting board body is interference-fitted with the inner wall of the mortise on the left-side skirting board body; The inner walls on both sides of the two mortises are provided with second limiting block grooves, and the outer walls of the two first limiting blocks on the main body of the right skirting board are slidably connected to the interior of the second limiting block grooves on the main body of the right skirting board.

[0009] Preferably, both outer walls at the rear ends of the two skirting board bodies are provided with top-out grooves, and the interiors of the four top-out grooves are respectively connected to the interiors of the corresponding second limiting block grooves; The upper rear surface of both skirting board bodies is provided with a second locking rod groove.

[0010] Preferably, a locking rod is slidably connected inside both of the two second locking rod grooves, and a first locking rod groove is provided on the upper surface of both tenons; Among them, the locking rod on the left skirting board body extends slidably into the mortise at one end near the second locking rod groove on the right skirting board body and slides in connection with the inside of the second locking rod groove on the right.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This retractable skirting board mortise and tenon joint structure, through the cooperation of the tenon groove in the positioning tenon assembly and the second compression spring, allows the tenon to automatically adapt to small angle deviations when inserted into the mortise, eliminating the need for high-precision alignment, greatly reducing installation difficulty and improving installation efficiency. It is especially suitable for large-area continuous installation, high-altitude operations and other scenarios with limited operation, reducing the increase in time and labor costs caused by installation difficulties, lowering the operation threshold for installers, and enabling ordinary workers to complete the installation efficiently. At the same time, the cooperation between the first limiting block and the first limiting block groove on the mortise side, plus the double locking of the locking rod and the first locking rod groove, restricts the movement of the tenon in the horizontal and vertical directions, making the connection more secure and less prone to loosening in daily use, ensuring the long-term stable use of the skirting board.

[0018] Please see Figure 1-4 This utility model provides a technical solution: a retractable skirting board tenon and mortise splicing structure, including two skirting board main bodies 1; Both skirting board bodies 1 are equipped with positioning tenon components; The positioning tenon assembly includes a tenon 5 and two first limiting blocks 7. The outer wall of the tenon 5 has two first limiting block grooves 6. The outer walls of the two first limiting blocks 7 are slidably connected to the interior of the corresponding first limiting block grooves 6. Each of the two first limiting block grooves 6 is provided with three first compression springs 9. The six first compression springs 9 are grouped in groups of three. The two ends of the two groups of first compression springs 9 are fixedly connected to the outer wall of the corresponding first limiting block 7 and the interior of the first limiting block groove 6, respectively. The front outer wall of the two skirting board bodies 1 is provided with a tenon sliding groove 8. One end of the outer wall of the tenon 5 is slidably connected to the interior of the corresponding tenon sliding groove 8.

[0019] Each of the two skirting board main bodies 1 has a mortise 12 on its rear outer wall. Each of the two tenon grooves 8 has three second compression springs 10 inside. The six second compression springs 10 are arranged in groups of three. The two ends of each group of two second compression springs 10 are fixedly connected to the outer wall of the corresponding tenon 5 and the inner wall of the tenon groove 8, respectively. The outer wall of the tenon 5 on the right skirting board main body 1 is interference-fitted with the interior of the mortise 12 on the left skirting board main body 1. The inner walls on both sides of each of the two mortise 12 have second limiting block grooves 11. The outer walls of the two first limiting blocks 7 on the right skirting board main body 1 are connected to the second limiting block grooves 11 on the right skirting board main body 1. The two skirting board bodies 1 have corresponding sliding connections. The outer walls on both sides of the rear end of each skirting board body 1 are provided with ejector grooves 3. The interior of each of the four ejector grooves 3 is connected to the interior of the corresponding second limiting block groove 11. The upper surface of the rear end of each skirting board body 1 is provided with a second locking rod groove 13. The interior of each of the two second locking rod grooves 13 is slidably connected with a locking rod 4. The upper surface of each of the two tenons 5 is provided with a first locking rod groove 2. The locking rod 4 on the left skirting board body 1 extends slidably into the interior of the mortise 12 near the second locking rod groove 13 on the right skirting board body 1 and is slidably connected to the interior of the second locking rod groove 13 on the right.

[0020] Furthermore, when using this device, firstly, align the tenon 5 of the right skirting board body 1 with the mortise 12 of the left skirting board body 1. Because there is a second compression spring 10 between the tenon 5 and the tenon groove 8, the tenon 5 extends forward along the tenon groove 8 under the assistance of the spring force, smoothly inserting into the mortise 12 to achieve an interference fit and complete the initial splicing. Then, as the tenon 5 is inserted into the mortise 12, the first limiting block 7 on the tenon 5 is squeezed by the inner wall of the mortise 12, compressing the first compression spring 9 and retracting into the first limiting block groove 6. When the tenon 5 is fully inserted into the mortise 12, the first limiting block 7 moves to the mortise. When the tenon 5 is in the second limiting block groove 11 position on both sides of the mortise 12, the first compression spring 9 releases its elastic force, pushing the first limiting block 7 out and sliding it into the second limiting block groove 11, restricting the movement of the tenon 5 within the mortise 12, initially locking the splicing structure and enhancing connection stability. Then, the locking rod 4 in the second locking rod groove 13 is slid, so that one end of the locking rod 4 extends into the mortise 12 and inserts into the first locking rod groove 2 on the tenon 5, restricting the movement of the tenon 5 from above, forming a double lock, greatly enhancing the stability of the splicing structure, completing the splicing, and preventing loosening during use. Then, when it is necessary to connect the two... When the two baseboard bodies 1 are separated, the sliding locking rod 4 is pulled out from the first locking rod groove 2 of the tenon 5, releasing the upper locking restriction. Then, through the ejection groove 3, a thin tool is inserted into the ejection groove 3 to push the first limiting block 7 to compress the first compression spring 9, causing it to retract into the first limiting block groove 6, releasing the first limiting block 7 from restricting the movement of the tenon 5 and preventing damage to the parts from forced disassembly. Then, it is moved back along the tenon groove 8 and pulled out from the mortise 12, realizing the disassembly of the two baseboard bodies 1 for individual maintenance or adjustment. The entire disassembly process is smooth, reducing maintenance difficulty. In terms of cost, in daily use, if the baseboard is subjected to slight external force, the first compression spring 9 and the second compression spring 10 can buffer the impact of the external force through their own elastic deformation, preventing the tenon 5 and mortise 12 from being directly subjected to rigid force and loosening. At the same time, the double locking structure ensures that the splice will not fail due to normal external force, maintaining the normal use of the baseboard. When the temperature and humidity of the environment change and the wood undergoes slight deformation, the elasticity of the springs can also adapt to a certain degree of dimensional change, ensuring the stability of the splicing structure. Compared with the structure in the background technology, it can better adapt to complex usage scenarios and environmental changes.

[0021] By cooperating with the tenon groove 8 and the second compression spring 10 in the positioning tenon assembly, the tenon 5 can automatically adapt to small angle deviations when inserted into the mortise 12, eliminating the need for high-precision alignment, greatly reducing installation difficulty and improving installation efficiency. It is especially suitable for large-area continuous installation, high-altitude operations and other operation-restricted scenarios, reducing the increase in time and labor costs caused by installation difficulties, lowering the operation threshold for installers, and enabling ordinary workers to complete the installation efficiently. At the same time, the cooperation between the first limiting block 7 and the second limiting block groove 11 on the mortise side, plus the double locking of the locking rod 4 and the first locking rod groove 2, restricts the movement of the tenon 5 in the horizontal and vertical directions, making the connection more secure and less prone to loosening in daily use, ensuring the long-term stable use of the skirting board.

[0022] Structural Description: Baseboard Body 1: As the basic carrier of the splicing structure, two baseboard bodies 1 are used to form a complete baseboard. It is equipped with various connection-related structures, such as the tenon groove 8 at the front end, the mortise 12 at the rear end, and the top groove 3 and the second locking rod groove 13 for installing other components. It is the basic framework for realizing splicing, telescopic and locking functions. Tenon 5: It is a key component for splicing two skirting board bodies 1. One end is slidably connected to the tenon groove 8 and can extend and retract in the groove. The outer wall has a first limiting block groove 6 for installing the first limiting block 7. The upper surface has a first locking rod groove 2, which cooperates with the locking rod 4 to achieve locking. First limiting block 7: Slidably connected in the first limiting block groove 6 of the tenon 5, and can be popped out or retracted by the action of the first compression spring 9. When popped out, it cooperates with the second limiting block groove 11 on both sides of the mortise 12 to restrict the movement of the tenon 5 and ensure the stability of the splicing. When retracted, it is convenient for the tenon 5 to be inserted into or removed from the mortise 12 to realize splicing or disassembly. First compression spring 9: Three springs are placed in the first limiting block groove 6, and the two ends are respectively connected to the first limiting block 7 and the inner wall of the first limiting block groove 6. They provide the spring force for the first limiting block 7 to pop out, so that it maintains the tendency to cooperate with the second limiting block groove 11 on the mortise side and enhance the stability of the splicing. The tenon groove 8 and the second compression spring 10 are formed on the outer wall of the front end of the skirting board body 1, providing sliding space for the tenon 5, restricting the sliding direction of the tenon 5, so that the tenon 5 can only extend and retract along the groove, ensuring the alignment accuracy during splicing, and improving the error tolerance and smoothness during installation. The second compression spring 10: three springs are placed in the tenon groove 8, with the two ends connected to the outer wall of the tenon 5 and the inner wall of the tenon groove 8 respectively. It provides elastic force for the expansion and contraction of the tenon 5. When splicing, it helps the tenon 5 to be inserted into the mortise 12. It can adapt to the insertion angle deviation to a certain extent, help the tenon 5 to be inserted smoothly, and reduce the risk of jamming due to limited operating space and poor vision. When disassembling, it can help the tenon 5 to retract. At the same time, in daily use, it can adapt to a certain external impact and maintain the stability of the splicing structure. The mortise 12 and the second limiting block groove 11: The mortise 12 is opened on the outer wall of the rear end of the skirting board body 1 to accommodate the tenon 5 of another skirting board body 1, so as to achieve an interference connection. It is the core docking structure for splicing. Its internal space shape is adapted to the tenon 5 to ensure the tightness of the connection. Compared with the simple slot structure in the background technology, the combination of the tenon slide 8 and the spring design makes it easier to achieve precise docking and smooth installation. Ejection groove 3: It is formed on both outer walls of the rear end of the skirting board body 1 and communicates with the second limiting block groove 11. Its function is to provide operating space for ejecting the first limiting block 7. When it is necessary to disassemble the skirting board body 1, the first limiting block 7 can be pushed back into the first limiting block groove 6 by means of tools or external force through the ejection groove 3, thereby releasing the movement restriction of the tenon 5, facilitating disassembly, solving the problem that the parts may be damaged due to forced disassembly in the background technology, and facilitating later maintenance. Locking rod 4 and second locking rod groove 13: Locking rod 4 is slidably connected in the second locking rod groove 13, and one end can slide to the inside of the mortise 12, cooperating with the first locking rod groove 2 on the tenon 5. When locking rod 4 is inserted into the first locking rod groove 2, it can restrict the movement of tenon 5 from above, forming a double lock together with the first limiting block 7, improving the stability of the splicing structure. Compared with the single locking rod reinforcement in the background technology, it further enhances the reliability of the connection. Sliding out locking rod 4 releases the upper lock, facilitating disassembly operations.

[0023] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
