Description

Technical Field

[0001] The utility model relates to the technical field of panel furniture connectors. Background Art

[0002] Panel furniture, such as cabinets and desks, has partitions assembled and fixed together using connectors that quickly connect the furniture panels. The current mainstream connector is a three-in-one connector, consisting of an eccentric wheel, a connecting rod, and an expanded plastic piece. The principle is as follows: holes are pre-punched in the panels according to the specifications of the three-in-one connector. During assembly, the expanded plastic piece is first inserted vertically into the mounting hole of the first panel. One end of the connecting rod is screwed into the expanded plastic piece, while the other end is aligned with the eccentric wheel. The eccentric wheel is then inserted into the circular hole of the second panel. The connecting rod of the first panel is then aligned with the mounting hole on the end face of the second panel and inserted into the eccentric wheel. Finally, the eccentric wheel is rotated with a screwdriver to clamp the connecting rod, achieving fixation between the two vertical panels.

[0003] However, the connecting rod and expanded plastic part of the existing three-in-one connector are fixed perpendicular to the plate. The connector protrudes from the plate surface and cannot retract, nor does it have space to retract. Therefore, when installing a shelf vertically between two parallel and fixed plates, the existing three-in-one connector cannot be installed due to the interference of the connecting rod. The two parallel plates need to be removed and reinstalled, which is time-consuming and labor-intensive. Therefore, a connector with more convenient installation is needed. Utility Model Content

[0004] The purpose of the utility model is to provide a connecting piece which is more convenient to install.

[0005] In order to achieve the above purpose, the technical solution adopted by the present utility model is:

[0006] A panel furniture connection structure for connecting and fixing between a first plate and a second plate arranged vertically, comprising a lock assembly fixed in the first plate and a locking rod assembly fixed in one end of the second plate; the locking rod assembly comprises an embedded sleeve embedded and fixed in the second plate, and a telescopic rod elastically installed in the embedded sleeve by a spring, the outer end of the telescopic rod having a T-head; the lock assembly comprises a first base body and a second base body arranged in parallel and embedded and fixed in the first plate, the first base body being locked to the second plate by screws, the outer end surface of the first base body being provided with an oblique sliding groove for the T-head to slide into, and the second base body being provided with a circular cavity with an axis perpendicular to the second plate, the circular cavity being coaxially provided with a first gear, The circular cavity is also provided with a rack meshing with the first gear, and one end of the rack has a locking portion that can penetrate into the first seat body from the side wall. When the first gear is rotated forward, the locking portion can completely enter the first seat body and prevent the T head from sliding out of the sliding groove; the outer end of the first gear is also concentrically fixed with a second gear, and the second gear has long teeth that extend around the reverse angle and can be radially deformed. The inner wall of the circular cavity has internal teeth meshing with the second gear, and the outer end surface of the circular cavity is also provided with an end cover, and the inner side of the end cover extends a pressure block that abuts against the radial outer side of the long teeth. When the end cover is rotated in the reverse direction, the long teeth can be disengaged from the inner teeth, thereby driving the rack to move in the reverse direction to unlock the T head.

[0007] In a preferred embodiment, the locking portion passes through the chute vertically from the side and abuts against the side of the T head facing the chute outlet.

[0008] In a preferred embodiment, the locking portion has a step portion on a side facing the T-head portion for preventing the T-head portion from axially retracting.

[0009] In a preferred embodiment, a center rod extends vertically from the inner side of the end cover and passes through the axis of the first gear, the second gear and the inner end face of the second seat body, and the end face of the center rod is locked with a T-head bolt that presses against the inner end face of the second seat body to limit the end cover from axially separating from the second seat body.

[0010] In a preferred embodiment, a first locking disk is integrally formed on one side of the first seat, and the first locking disk has an oblique hole for a screw to be obliquely locked into the first plate.

[0011] In a preferred embodiment, the second seat body and the first seat body are plug-fitted with each other through a mortise and tenon structure.

[0012] In a preferred solution, the outer peripheral wall of the insert sleeve has a self-tapping thread.

[0013] In a preferred embodiment, a second locking disc is integrally formed on one side of the embedded sleeve, and the second locking disc has an oblique hole for screws to be obliquely locked into the second plate.

[0014] In a preferred embodiment, the other end of the telescopic rod passes through the embedded sleeve to form a connecting rod of a three-in-one connector; at this time, the spring sleeve is arranged on the outer periphery of the telescopic rod, and the two ends are respectively pressed between the embedded sleeve and the telescopic rod.

[0015] The present invention has the following advantages: during installation, the latch assembly is first installed into the first plate, and then the locking rod assembly is installed into the end of the second plate. When the shelf needs to be installed between the two plates, the telescopic rod can be retracted. When it is aligned with the slide slot entrance of the latch assembly, the telescopic rod automatically extends and slides into the slide slot of the latch assembly under the action of the spring. Then, the end cap is rotated forward. Driven by the first gear, the locking portion of the rack fully enters the second seat and locks the T-head of the telescopic rod, preventing it from exiting the slide slot, thereby completing the installation and fixing. Because the second gear is tilted in the opposite direction, it cannot rotate in the opposite direction without external interference, that is, the rack cannot retreat, and the locking portion can reliably lock the T-head. When it is necessary to remove the furniture, it is only necessary to rotate the end cap in the opposite direction. Under the pressure of the pressure block, the long teeth of the second gear are radially deformed and disengaged from the inner teeth, and then the rack can be rotated and retreated, completing the unlocking. Therefore, this connection structure not only makes furniture installation simpler and more efficient, but also has high structural reliability. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] Example 1:

[0026] refer to Figures 1 to 5 , a panel furniture connection structure of the present embodiment is used to connect and be fixed between a first plate A and a second plate B arranged vertically, including a lock component 1 fixed in the first plate A, and a lock rod component 2 fixed in one end of the second plate B; the lock rod component 2 includes an embedded sleeve 21 embedded and fixed in the second plate B, and a telescopic rod 23 elastically installed in the embedded sleeve 21 by a spring 22, and the outer end of the telescopic rod 23 has a T head 231; the lock component 1 includes a first base body 11 and a second base body 12 arranged in parallel and embedded and fixed in the first plate A, the first base body 11 is locked on the second plate B by screws, the outer end surface of the first base body 11 is provided with an oblique sliding groove 111 for the T head 231 to slide into, and the second base body 12 is provided with a circular cavity 121 whose axis is perpendicular to the second plate B, the circular cavity 121 is coaxially provided with a first gear 122, and the circular cavity 121 is also provided with a first gear 122 which is coaxial with the first gear A rack 123 is engaged with a gear 122, and one end of the rack 123 has a locking portion 124 that can penetrate into the first seat body 11 from the side wall. When the first gear 122 is rotated in the forward direction, the locking portion 124 can completely enter the first seat body 11 and prevent the T head 231 from sliding out of the sliding groove 111; the outer end of the first gear 122 is also concentrically fixed with a second gear 125, which has a reverse tilt extending and radially deformable The long tooth 1251 and the inner wall of the circular cavity 121 have an inner tooth 1211 meshing with the second gear 125, and the outer end face of the circular cavity 121 is further provided with an end cover 126. The inner side of the end cover 126 extends a pressure block 1261 that abuts against the radial outer side of the long tooth 1251. When the end cover 126 is rotated in the reverse direction, the long tooth 1251 can be disengaged from the inner tooth 1211, thereby driving the rack 123 to move in the reverse direction to unlock the T head 231.

[0027] Usually, a first mounting hole for mounting the lock catch assembly 1 is pre-opened on the first plate A at the factory, and a second mounting hole for mounting the lock rod assembly 2 is pre-opened at the end of the second plate B. When installing, first install the lock catch assembly 1 into the first plate A and lock it with screws, then install the locking rod assembly 2 into the end of the second plate B. When the layer plate needs to be installed between the two plates, the telescopic rod 23 can be retracted. When it is aligned with the entrance of the slide groove 111 of the lock catch assembly 1, the telescopic rod 23 automatically extends and slides into the slide groove 111 of the lock catch assembly 1 under the action of the spring 22, and then the end cover 126 is rotated forward. At this time, the first gear 122 and the second gear 125 can both rotate forward. Under the drive of the first gear 122, the locking portion 124 of the rack 123 completely enters the second seat body 12 and locks the T head 231 of the telescopic rod 23, making it unable to exit the slide groove 111, thereby completing the installation and fixing. Since the second gear 125 is tilted in the opposite direction, the second gear 125 cannot rotate in the opposite direction without external interference, that is, the rack 123 cannot retreat, thereby making the locking portion 124 able to reliably lock the T head 231. To remove the second gear 125, simply rotate the end cap 126 in the opposite direction. Under the pressure of the pressing block 1261, the long teeth 1251 of the second gear 125 deform radially and disengage from the inner teeth 1211, which then rotates and drives the rack 123 back, completing the unlocking process. Therefore, this connection structure not only makes furniture installation simpler and more efficient, but also has a high structural reliability.

[0028] In a preferred embodiment, the locking portion 124 of this embodiment extends vertically through the chute 111 from the side and abuts against the side of the T-head portion 231 facing the exit of the chute 111. The locking portion 124 passes through the first base 11 and cannot swing, thereby locking the T-head portion 231 of the telescopic rod 23 within the chute 111 and preventing it from sliding out. In other embodiments, the locking portion 124 can also prevent the T-head portion 231 from sliding out of the chute 111 by inserting into the T-head portion 231.

[0029] In a preferred embodiment, the locking portion 124 of this embodiment has a step portion 1241 on the side facing the T-head portion 231 to prevent the T-head portion 231 from axially retracting, thereby further improving the reliability of the connection.

[0030] In a preferred embodiment, a center rod 1262 extends vertically from the inner side of the end cover 126 of this embodiment, passing through the first gear 122, the second gear 125, and the axis of the inner end surface of the second base body 12. A T-head bolt is fixed to the end surface of the center rod 1262, which abuts against the inner end surface of the second base body 12 to prevent the end cover 126 from axially separating from the second base body 12. Not only can the end cover 126 be axially mounted on the second base body 12 via the T-head bolt and the center rod 1262, but the center rod 1262 also serves as the rotational axis of the first gear 122 and the second gear 125, making the structure within the second base body 12 compact, reasonable, and stable.

[0031] In a preferred embodiment, a first locking disc 13 is integrally formed on one side of the first base 11 of this embodiment. The first locking disc 13 has an oblique hole for a screw to be obliquely locked into the second plate B. The first base 11 is secured to the first plate A by a screw that passes obliquely through the first locking disc 13. Because the force acting to loosen the first base 11 outward is different from the direction of the screw's locking, the first base 11 can withstand greater external forces without separating from the first plate A, making the installation of the lock assembly 1 more reliable.

[0032] In a preferred embodiment, a second locking disc 24 is integrally formed on one side of the insert sleeve 21 of this embodiment. The second locking disc 24 has an oblique hole for screws to be screwed obliquely into the second plate B. Similarly, the locking rod assembly 2 is secured to the second plate B by screws that obliquely pass through the second locking disc 24. This allows the locking rod assembly 2 to withstand greater external forces without disengaging from the second plate B, making installation more secure.

[0033] In a preferred embodiment, the second base 12 is plugged into the first base 11 via a mortise and tenon structure 100. If any problems arise with the internal structure of the second base 12, it can be removed and replaced. In simpler assembly situations, when locking the telescopic rod 23 is not necessary, the second base 12 can also be removed.

[0034] Example 2:

[0035] refer to Figure 6 The structural principles of this embodiment are essentially the same as those of the first embodiment, with the difference being that the insert sleeve 21 is secured to the second plate B in a different manner. In this embodiment, the outer wall of the insert sleeve 21 has self-tapping threads 21a. The insert sleeve 21 is secured to the second plate B using self-tapping screws, replacing the second locking disc 24 of the first embodiment.

[0036] Example 3:

[0037] refer to Figure 7 The structural principles of this embodiment are essentially the same as those of the first embodiment, differing in that the method of securing the insert sleeve 21 to the second plate B is different. In this embodiment, the other end of the telescopic rod 23 extends beyond the rear end of the insert sleeve 21 to form a connecting rod 23a of the three-in-one connector. This, in conjunction with the eccentric wheel of the existing three-in-one connector, can be locked to the second plate B. The spring 22 is sleeved around the outer circumference of the telescopic rod 23. Both the insert sleeve 21 and the telescopic rod 23 have radially projecting stoppers, with the ends of the spring 22 resting between the stoppers of the insert sleeve 21 and the telescopic rod 23, respectively.

[0038] The above description does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
