Description

Technical Field

[0001] This utility model relates to the field of quick-assembly furniture connectors, and in particular to a splicing kit for quick-assembly furniture. Background Technology

[0002] With the development of the times, modular furniture has gradually become popular. Modular furniture is simple to assemble, easy to standardize production and on-site assembly, and is especially popular among people who like to do DIY. The core of modular furniture design is to divide the furniture into easy-to-assemble unit panels. The panel connectors are mechanisms specifically used to connect and fix adjacent panels. Currently, some commonly used panel connectors have complex structures that require professional tools for connection, which is not conducive to manual DIY operations. Some have poor assembly precision, and the structure is unstable after assembly, and it is easy to fall apart under stress. In order to solve this problem, our company has applied for a furniture panel quick-assembly splicing kit with application number 2023210103259. This kit has good precision and stable structure. However, in actual use, assemblers have reported that when connecting the six-way connector to the splicing rod, because the connection bolt is used in the middle, the six-way connector and the splicing rod need to rotate relative to each other. At the end point of the rotation, the splicing surface of the six-way connector and the end face of the splicing rod often cannot be aligned exactly, requiring manual adjustment. However, after adjustment, there is usually a certain gap in the middle. To address the gap issue, our company further developed a splicing rod for a six-way connector based on the aforementioned patent (application number 2025204846215). This splicing rod is used in conjunction with the six-way connector. During the splicing process, a bevel gear is used to convert the vertical rotation of the screwdriver into horizontal rotation, resulting in better compactness. However, during actual installation, we found that the drive shaft in the middle can slide relative to the drive shaft positioning seat during installation. Therefore, it sometimes falls off along with the forward screw during installation, affecting the overall assembly efficiency. Utility Model Content

[0011] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0012] Please see Figures 1 to 5 A preferred embodiment of this utility model includes: A quick-assembly furniture assembly kit, comprising a six-way connector 2, an assembly rod 3, and an assembly plug 1, wherein each assembly surface of the six-way connector 2 is square, each assembly surface has a threaded connection hole in the center, and each assembly surface has positioning protrusions at its four corners. The splicing rod 3 has a square cross-section that matches the splicing surface. The four corners of the cross-section have grooves that match the protrusions. The splicing rod 3 has elongated grooves of the same specifications on all four sides of its body. The openings of the elongated grooves have a pressure-edge structure. A through-hole is located in the middle of the rod body. Positioning slots 301 are symmetrically positioned at both ends of the splicing rod 3, relying on the elongated grooves. The bottom of the positioning slot 301 is the inner wall of the corresponding straight hole, and the opening of the positioning slot 301 is the opening of the end of the elongated groove. The splicing plug 1 includes a splicing base 101, a threaded sleeve 103, and a sleeve drive mechanism. The overall shape of the splicing base 101 matches the shape of the positioning slot 301 at the top of the splicing rod 3. When the splicing base 101 is inserted into the positioning slot, its rear end is flush with the end face of the splicing rod 3. A drive mechanism mounting position is provided inside the splicing base 101, and the sleeve drive mechanism is mounted on this driving mechanism mounting position. The outer diameter of the threaded sleeve 103 is the same as the inner diameter of the straight hole. Its top end has a forward thread 1033 that matches the threaded connection hole on the six-way connector 2, and its tail end has a socket 1031. A compression spring 107 is installed in the socket 1031. The sleeve drive mechanism includes a radial gear drive shaft 105, an axial gear drive shaft 102, and an axial limiting clamp 104. The drive mechanism mounting position is located at the front end inside the splicing base 101, including a radial power mounting hole 1015 and a clamp fixing position 1014. The radial gear drive shaft 105 includes a power input shaft 1052 and a driving bevel gear 105 disposed at the top end of the power output shaft 1052. 1. The power output shaft 1052 has a transmission groove at its tail end. The axial gear transmission shaft 102 includes a transmission shaft 1022 and a driven bevel gear 1021 disposed at the top of the transmission shaft 1022. The power input shaft 1052 is inserted into the radial power mounting hole 1015. The limiting clamp 104 is inserted into the clamp fixing position 1014. The shaft body of the transmission shaft 1022 passes through the limiting clamp 104 and is inserted into the socket insertion hole 1031 and connected to the threaded sleeve 103. At this time, the limiting clamp 104 abuts against the driven bevel gear 1021, and the driving bevel gear 1051 and the driven bevel gear 1021 are perpendicularly meshed.The threaded sleeve 103 is fitted onto the drive shaft. The central axis of the threaded sleeve 103 coincides with the central axis of the straight hole in the middle of the splicing rod 3. While the threaded sleeve 103 is radially fixed relative to the sleeve drive mechanism, it can slide horizontally relative to the drive shaft 1022. After the splicing seat 101 is inserted into the splicing slot 301, the threaded sleeve 103 can be rotated by inserting a screwdriver into the power groove on the power input shaft 1052 outside the splicing seat 101 and then rotating the screwdriver. This allows the threaded sleeve 103 to rotate as a whole, so that the advancing thread 1033 can enter or disengage from the threaded connection hole as needed. During this process, because a compression spring is installed in the threaded sleeve, the threaded sleeve 103 and the drive shaft 1022 can maintain an elastically open state, which not only prevents them from loosening along the axis but also ensures that the advancing thread 1033 will not jam due to misalignment when entering the threaded connection hole.

[0013] The threaded sleeve 103 has a pair of axially limiting elongated holes 1032 symmetrically arranged on both sides of the socket 1031, penetrating the hole wall. The top end of the drive shaft 1022 has a through-hole limiting pin hole 1023. The top end of the drive shaft 1022 extends into the socket, pressing against the internal compression spring 107. Then, a sliding limiting pin 106 is installed in the limiting pin hole 1023, connecting the drive shaft 1022 and the threaded sleeve 103 together. The length of the sliding limiting pin 106 is the same as the outer diameter of the threaded sleeve 103. In this way, the threaded sleeve 103 can be stably connected to the drive shaft 1022, ensuring that the two can move horizontally relative to each other while achieving radial locking. Moreover, the sliding limiting pin 106 does not affect the rotation of the threaded sleeve 103.

[0014] The splicing base 101 has a positioning plug 1012 at its top end. The diameter of the positioning plug 1012 is the same as the inner diameter of the straight hole. The positioning plug 1012 has a radially penetrating pin hole. The splicing rod 3 also has a corresponding positioning pin hole 302 at a corresponding position on its body. When the splicing base 101 is inserted into the positioning slot 301, the positioning plug 1012 is inserted into the straight hole. The pin hole and the positioning pin hole 302 are connected by a positioning pin 4. The positioning plug 1012 can further improve the compactness of the splicing base 101 after it is installed in the positioning slot 302 and prevent the splicing base 101 from shaking axially due to dimensional errors after installation.

[0015] The splicing base 101 is provided with a sleeve clamping block 1013 corresponding to the position of the threaded sleeve 103. The inner surface of the sleeve clamping block 1013 is provided with an arc surface with the same radius as the threaded sleeve 103, and the center line of the arc surface coincides with the center line of the threaded sleeve 103. The two sides of the sleeve clamping block 1013 extend beyond the splicing base body 1011, and the parts extending beyond the splicing base body 1011 form a retaining strip structure that matches the pressure edge structure of the long groove. The arc surface of the sleeve clamping block 1013 can be tightly attached to the threaded sleeve 103, so that the threaded sleeve 103 will not wobble radially during rotation. Moreover, the retaining strip structure on both sides cooperates with the pressure edge structure to effectively prevent the splicing base 101 from radially loosening after being inserted into the positioning slot 302.

[0016] Please see Figure 1 , Figure 2 , Figure 3 and Figure 6 Another preferred embodiment of this utility model includes: A quick-assembly furniture assembly kit, comprising a six-way connector 2, an assembly rod 3, and an assembly plug 1, wherein each assembly surface of the six-way connector 2 is square, each assembly surface has a threaded connection hole in the center, and each assembly surface has positioning protrusions at its four corners. The splicing rod 3 has a square cross-section that matches the splicing surface. The four corners of the cross-section have grooves that match the protrusions. The splicing rod 3 has elongated grooves of the same specifications on all four sides of its body. The openings of the elongated grooves have a pressure-edge structure. A through-hole is located in the middle of the rod body. Positioning slots 301 are symmetrically positioned at both ends of the splicing rod 3, relying on the elongated grooves. The bottom of the positioning slot 301 is the inner wall of the corresponding straight hole, and the opening of the positioning slot 301 is the opening of the end of the elongated groove. The splicing plug 1 includes a splicing base 101, a threaded sleeve 103, and a sleeve drive mechanism. The overall shape of the splicing base 101 matches the shape of the positioning slot 301 at the top of the splicing rod 3. When the splicing base 101 is inserted into the positioning slot, its rear end is flush with the end face of the splicing rod 3. A drive mechanism mounting position is provided inside the splicing base 101, and the sleeve drive mechanism is mounted on this driving mechanism mounting position. The outer diameter of the threaded sleeve 103 is the same as the inner diameter of the straight hole. Its top end has a forward thread 1033 that matches the threaded connection hole on the six-way connector 2, and its tail end has a socket 1031. A compression spring 107 is installed in the socket 1031. The sleeve drive mechanism includes a radial gear drive shaft 105, an axial gear drive shaft 102, and an axial limiting clamp 104. The drive mechanism mounting position is located at the front end inside the splicing base 101, including a radial power mounting hole 1015 and a clamp fixing position 1014.

The power output shaft 1052 has a transmission groove at its tail end. The axial gear transmission shaft 102 includes a transmission shaft 1022 and a driven bevel gear 1021 disposed at the top of the transmission shaft 1022. The power input shaft 1052 is inserted into the radial power mounting hole 1015. The limiting clamp 104 is inserted into the clamp fixing position 1014. The shaft body of the transmission shaft 1022 passes through the limiting clamp 104 and is inserted into the socket insertion hole 1031 and connected to the threaded sleeve 103. At this time, the limiting clamp 104 abuts against the driven bevel gear 1021, and the driving bevel gear 1051 and the driven bevel gear 1021 are perpendicularly meshed.

[0017] The threaded sleeve 103 is fitted onto the drive shaft. The central axis of the threaded sleeve 103 coincides with the central axis of the straight hole in the middle of the splicing rod 3. While the threaded sleeve 103 is radially fixed relative to the sleeve drive mechanism, it can slide horizontally relative to the drive shaft 1022. After the splicing seat 101 is inserted into the splicing slot 301, the threaded sleeve 103 can be rotated by inserting a screwdriver into the power groove on the power input shaft 1052 outside the splicing seat 101 and then rotating the screwdriver. This allows the threaded sleeve 103 to rotate as a whole, so that the advancing thread 1033 can enter or disengage from the threaded connection hole as needed. During this process, because a compression spring is installed in the threaded sleeve, the threaded sleeve 103 and the drive shaft 1022 can maintain an elastically open state, which not only prevents them from loosening along the axis but also ensures that the advancing thread 1033 will not jam due to misalignment when entering the threaded connection hole.

[0018] The threaded sleeve 103 has a pair of axially limiting elongated holes 1032 symmetrically arranged on both sides of the socket 1031. Two L-shaped guide grooves 1034 are symmetrically arranged on the wall of the socket 1031 about the center line of the socket 1031. One end of each guide groove 1034 opens onto the opening of the socket 1031, and the other end opens in the middle of the corresponding axially limiting elongated hole 1032. A sliding limiting pin 106 is installed at the top of the drive shaft 1022. The length of the sliding limiting pin 106 is the same as the outer diameter of the threaded sleeve 103. The top of the drive shaft 1022 extends into the socket 1031, and both ends of the sliding limiting pin 106 enter the corresponding guide grooves 1034. After rotation, the pin enters the axially limiting elongated hole 1032, connecting the drive shaft and the threaded sleeve 103. In this way, the threaded sleeve 103 can be stably connected to the drive shaft 1022 and radially locked while ensuring that the two can move horizontally relative to each other. Moreover, the sliding limit pin 106 will not affect the rotation of the threaded sleeve 103.

[0019] The splicing base 101 has a positioning plug 1012 at its top end. The diameter of the positioning plug 1012 is the same as the inner diameter of the straight hole. The positioning plug 1012 has a radially penetrating pin hole. The splicing rod 3 also has a corresponding positioning pin hole 302 at a corresponding position on its body. When the splicing base 101 is inserted into the positioning slot 301, the positioning plug 1012 is inserted into the straight hole. The pin hole and the positioning pin hole 302 are connected by a positioning pin 4. The positioning plug 1012 can further improve the compactness of the splicing base 101 after it is installed in the positioning slot 302 and prevent the splicing base 101 from shaking axially due to dimensional errors after installation.

[0020] The splicing base 101 is provided with a sleeve clamping block 1013 corresponding to the position of the threaded sleeve 103. The inner surface of the sleeve clamping block 1013 is provided with an arc surface with the same radius as the threaded sleeve 103, and the center line of the arc surface coincides with the center line of the threaded sleeve 103. The two sides of the sleeve clamping block 1013 extend beyond the splicing base body 1011, and the parts extending beyond the splicing base body 1011 form a retaining strip structure that matches the pressure edge structure of the long groove. The arc surface of the sleeve clamping block 1013 can be tightly attached to the threaded sleeve 103, so that the threaded sleeve 103 will not wobble radially during rotation. Moreover, the retaining strip structure on both sides cooperates with the pressure edge structure to effectively prevent the splicing base 101 from radially loosening after being inserted into the positioning slot 302.
