Description

Technical Field

[0001] The present invention relates to the technical field of connecting components, and in particular to a prefabricated connector kit structure and a method of using the same. Background Art

[0002] As the core connection method in traditional Chinese architecture and woodworking, the mortise and tenon structure is still widely used in modern wooden structures (such as prefabricated wooden buildings, custom furniture, and landscape garden facilities) because it does not require nails or rivets and has a stable structure.

[0003] However, the fixation of mortise and tenon joints in the existing technology still has significant defects, which requires a high level of craftsmanship, and there is a certain margin after installation, which makes it easy for the connected components to shake. The stable fixation process in the existing technology mostly relies on pre-drilling and then screwing in bolts, screws or self-tapping screws to achieve fastening, which requires threaded holes to be opened on the surface of the wooden base. The exposed threads affect the overall aesthetics, especially in scenes with strict requirements on appearance such as landscape architecture and high-end furniture, which is difficult to promote and apply. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above technical defects and provide a prefabricated connector kit structure and a method of using the same that can ensure both aesthetics and connection strength.

[0005] To solve the above technical problems, the present invention provides a technical solution: a prefabricated connector kit structure, comprising an embedded sleeve, a fixing lock for fixing the embedded sleeve, and a connecting beam connected between two sets of embedded sleeves or connected to any embedded sleeve, wherein the connecting beam is further engaged with an anti-slip filling sleeve;

[0006] A through hole is provided between the two side walls and the two top walls of the embedded sleeve, the inner diameter of the through hole is larger than the outer diameter of the connecting beam and is tightly fitted with the connecting beam;

[0007] The fixed lock includes lock heads arranged in pairs and a lock shaft for connecting the two sets of lock heads, and the lock shaft passes through a vertically opened through hole.

[0008] Preferably, both ends of the connecting beam are respectively provided with quick-release grooves and quick-release feet that cooperate with each other, and adjacent connecting beams are fixed by inserting the quick-release grooves and the quick-release feet.

[0009] Preferably, the quick-release slot and the quick-release foot are both wedge-shaped.

[0010] Preferably, a threaded extension rod is connected to either end of the connecting beam.

[0011] Preferably, the connecting beam is provided with an inward-concave fitting groove along its circumference direction, and multiple groups of inward-concave fitting grooves are provided along its length direction. A sleeve groove that can accommodate the connecting beam is opened in the middle of the anti-slip filling sleeve, and a convex ring is protruded on the inner wall of the sleeve groove to cooperate with the outside of the fitting groove.

[0012] Preferably, the upper end and the lower end of the lock shaft are both provided with threads, and the lock head includes a fitting head and an inner screw ring sleeved in the fitting head;

[0013] The inner screw ring is threadedly connected to the lock shaft, and the through holes at the top and bottom of the embedded sleeve are both matched with the embedded head to form a locking groove;

[0014] The connecting beam is provided with an accommodating groove for accommodating the engaging head, and an axis hole for accommodating the locking shaft is provided in the accommodating groove.

[0015] Preferably, it further comprises a stealth plate connected to the chimeric head, wherein a snap-fit head is provided on the top of the chimeric head around the inner screw ring;

[0016] An elastic clamping ring is provided on the side of the invisible plate facing the clamping head, and the elastic clamping ring is clamped and connected with the clamping head.

[0017] Another aspect of the present invention discloses a method for using a prefabricated connector kit, comprising the following steps:

[0018] S1: Milling holes in the connection area of the connecting components;

[0019] S2: Push the embedded sleeve into the milling hole;

[0020] S3: The connecting beam is inserted into the horizontal through hole of the corresponding embedded sleeve;

[0021] S4: Use a fixed lock to lock the connecting beam, embedded sleeve and connecting components;

[0022] S5: Press the invisible plate until the invisible hole engages with the fixing lock.

[0023] The advantages of the present invention over the prior art are: in the present invention, by providing a prefabricated embedded sleeve, a connecting beam and a fixing lock, the locking of the connecting component and the connector kit structure is achieved, and the threaded locking ensures the connection strength and prevents shaking at the connection. At the same time, based on the internal fixation concept design, it can be hidden in the connecting component, and the additional invisible plate further ensures the invisible beauty, which is easy to promote and apply.

[0031] The present invention will be described in further detail below with reference to the accompanying drawings.

[0032] Combined with attachment Figure 1-6 As shown, a prefabricated connector kit structure includes an embedded sleeve 1, a fixing lock 2 for fixing the embedded sleeve 1 and a connecting beam 3 connected between two groups of embedded sleeves 1 or connected to any embedded sleeve 1, and an anti-slip filling sleeve 4 is also clamped on the connecting beam 3.

[0033] Among them, the anti-slip filling sleeve 4 can be stuck into the milling hole opened in the component to be connected, increasing the structural strength during use and preventing the structural strength of the structure from changing due to the hollowness of the milling hole, and the embedded sleeve 1 and the fixed lock 2 cooperate with the connecting beam 3 to complete the locking of adjacent components to be connected.

[0034] During specific use, through holes 5 are provided between the two side walls and the two top walls of the embedded sleeve 1. The inner diameter of the through hole 5 is larger than the outer diameter of the connecting beam 3 and fits tightly with the connecting beam 3, making it convenient for the connecting beam to be inserted into the corresponding through hole 5. The fixed lock 2 includes a pair of locking heads 6 and a locking shaft 7 for connecting the two sets of locking heads 6. The locking shaft 7 passes through the vertically opened through hole 5, and the locking shaft completes the locking of the locking heads, embedded sleeves, connecting beams and connecting components.

[0035] In one embodiment:

[0036] Both ends of the connecting beam 3 are respectively provided with a quick-release groove 8 and a quick-release foot 9 that cooperate with each other. Adjacent connecting beams 3 are fixed by inserting the quick-release groove 8 and the quick-release foot 9. The quick-release groove 8 and the quick-release foot 9 are both wedge-shaped, which is convenient for quick disassembly and assembly. After the connecting beam is fixed, the embedded sleeve, lock head and other components cooperate to ensure the stability of the structure during use.

[0037] Different from the above embodiment, a threaded extension rod 10 is further connected to either end of the connecting beam 3. For connecting components that cannot be installed with the embedded sleeve 1, a screw hole can be opened and the threaded extension rod 10 can be screwed in, and the other end can be fixed normally with the embedded sleeve 1.

[0038] In one embodiment:

[0039] The connecting beam 3 is provided with an inward-deep fitting groove 11 along its circumference direction, and multiple groups of inward-deep fitting grooves 11 are provided along its length direction. A sleeve groove 12 for accommodating the connecting beam 3 is opened in the middle of the anti-slip filling sleeve 4, and the inner wall of the sleeve groove 12 cooperates with the inward-fitting groove 11 to form a convex ring 13, thereby completing the sleeve installation of the anti-slip filling sleeve 4.

[0040] Among them, when the fixed lock is in use, the upper and lower ends of the lock shaft 7 are both equipped with threads, the lock head 6 includes a fitting head 14, an inner screw ring 15 sleeved in the fitting head 14, and the inner screw ring 15 is threadedly connected to the lock shaft 7, and the through holes 5 at the top and bottom of the embedded sleeve 1 are both equipped with locking grooves 16 in the fitting head 14. At the same time, a receiving groove 17 for accommodating the fitting head 14 is provided in the connecting beam 3, and an axial hole 18 for accommodating the lock shaft 7 is opened in the receiving groove 17. The fitting head 14 is fixed by the receiving groove 17, and the lock shaft 7 is threadedly connected and locked using the inner screw ring 15.

[0041] In order to ensure aesthetics, it also includes an invisible plate 19 connected to the chimeric head 14. A locking head 20 is provided on the top of the chimeric head 14 around the inner screw ring 15; an elastic clamping ring 21 is provided on the side of the invisible plate 19 facing the locking head 20, and the elastic clamping ring 21 is engaged with the locking head 20.

[0042] During the specific implementation of the present invention, according to the structure to be assembled, the connection area of the connecting component is milled, and an invisible plate mounting hole corresponding to the depth of the milled hole is opened on the surface of the connecting component to facilitate subsequent invisible installation. The embedded sleeve 1 is pushed into the milled hole, and the connecting beam 3 is inserted into the horizontal through hole 5 corresponding to the embedded sleeve 1. The fixing lock 2 is used to lock the connecting beam 3, the embedded sleeve 1 and the connecting component, specifically the locking shaft, which is inserted into the vertical through hole and passes through the shaft hole 18 at the same time. The two ends of the shaft are threadedly locked by the installed internal screw ring 15, and the engaging head 14 is snapped into the corresponding receiving groove 17. The invisible plate 19 is pressed to the invisible hole to engage with the fixing lock 2 to fill the invisible opening, ensuring beauty and practicality.
