Description

Technical Field

[0001] The present invention relates to the technical field of partition connection, and in particular to a connection system and method for building block-type quick installation of a cabinet. Background Art

[0002] At present, when cabinet layers or partitions are connected in the furniture industry, two-in-one or three-in-one connectors are usually used. When installing the traditional two-in-one or three-in-one connectors, the cabinet needs to be laid down and assembled according to the steps.

[0003] When traditional three-in-one connectors are connected and installed, it is necessary to punch a wheel mounting hole and an embedded part mounting hole on the first plate and the second plate respectively, as well as a connecting rod mounting hole located below the wheel mounting hole. When installing, generally the embedded part is first installed on the second plate, and then the connecting rod is screwed into the embedded part. Then, the first plate and the second plate that need to be connected are aligned, and the connector is inserted and installed into the connector mounting hole. Then, the rotating wheel is installed in the wheel mounting hole of the first plate, and then the rotating wheel is screwed to complete the fastening of the first plate and the second plate.

[0004] However, the above-mentioned installation method requires the installation of shelves and partitions while assembling the cabinet body. After the installation is completed, they cannot be freely disassembled and combined. In addition, the installation method is relatively cumbersome and the installation efficiency is low. After the installation is completed, the assembled cabinet body needs to be pushed to flip from a lying state to an upright state. In the process of pushing it to flip, there is also a risk of it falling and injuring the installer.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0064] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0065] Embodiment 1:

[0066] like Figures 1 to 9 As shown, this embodiment provides a cabinet building block quick installation connection system, including a rotating wheel 2 for installation on a first plate member, a pre-embedded expansion assembly 3 for pre-embedded installation on a second plate member 5, and a rod sleeve assembly 1 for connecting and locking the first plate member 4 and the second plate member 5, wherein:

[0067] The rod sleeve assembly 1 includes a housing assembly and a connecting rod body 11 disposed in the housing assembly and reciprocating along the axial direction thereof; both ends of the connecting rod body 11 extend out of the housing assembly and are respectively provided with a first end 111 for clamping into the rotating wheel 2 and a second end 112 for clamping into the expansion assembly 3;

[0068] It also includes an elastic member body for pushing the connecting rod body 11 to move toward the second end 112 . The elastic member body is sleeved on the connecting rod body 11 and is located in the housing assembly.

[0069] The present embodiment redesigns the rod sleeve assembly 1 with the first end 111 and the second end 112, so that after the rotating wheel 2 and the expansion assembly 3 are respectively installed on the first plate 4 and the second plate 5, the rod sleeve assembly 1 can be inserted into the first plate 4. Since the connecting rod body 11 in the rod sleeve assembly 1 can reciprocate in the shell assembly, when the first plate 4 and the second plate 5 are connected and installed, the first plate 4 can be directly pressed and pushed to the corresponding position of the second plate 5, so that the second end 112 of the rod sleeve assembly 1 is stuck in the expansion assembly 3, and then the rotating wheel 2 is driven to rotate, and the connecting rod body 11 is driven to move in the direction of the first end 111, so that the second end 112 and the expansion assembly 3, as well as the first end 111 and the rotating wheel 2 are locked, and then the first plate 4 and the second plate 5 are locked.

[0070] In the present embodiment, in order to disassemble the first plate 4 and the second plate 5, the rotating wheel 2 can be directly screwed to move the connecting rod body 11 toward the second end 112. At this time, the second end 112 and the expansion assembly 3 are no longer in a completely locked state. At this time, the first plate 4 can be pushed or pulled out of the second plate 5. When pushing or pulling the first plate 4 and the second plate 5 to separate, it is only necessary to overcome the elastic force of the elastic member body. The separation process of the first plate 4 and the second plate 5 is relatively easy and convenient.

[0071] Therefore, the core key point of this embodiment is that, by utilizing the mutual cooperation of the rotating wheel 2, the specially designed rod sleeve assembly 1 and the expansion assembly 3, the connection system and connection process reconstructed in this application completely overturn the traditional cabinet installation process, so that before the first plate 4 and the second plate 5 are completely locked, the first plate 4 can easily overcome the elastic force of the elastic member body to clamp in or move out of the expansion assembly 3 of the second plate 5, and after the first plate 4 and the second plate 5 are locked, the first end 111 and the second end 112 of the connecting rod body 11 are respectively completely clamped in the rotating wheel 2 and the expansion assembly 3, and under the action of tension, the connection between the first plate 4 and the second plate 5 can be made extremely firm; the locking state and the loose state of the first plate 4 and the second plate 5 of this application can be achieved only by screwing the rotating wheel 2, so that the installation and disassembly of the first plate 4 and the second plate 5 are extremely convenient, which can not only achieve the technical effect that each layer and partition can be disassembled and combined at any time, but also reduce the labor intensity of workers, greatly reduce the risk of on-site installation of workers, and improve the efficiency of cabinet installation.

[0072] Specifically, in this embodiment, if Figure 2 As shown, the connecting rod body 11 is also provided with a limiting protrusion 115 located in the housing assembly;

[0073] One end of the elastic member body presses against the limiting protrusion 115, and the other end presses against the housing assembly. By providing the elastic member body, after the rod sleeve assembly 1 is installed in the first plate member 4, the second end 112 has a tendency to protrude outwards under the elastic force of the elastic member body. During the process of installing and connecting the first plate member 4 and the second plate member 5, after pressing the first plate member 4 against the second plate member 5, the compressed elastic member body continuously applies pressure to the limiting protrusion 115, so that after the second end 112 of the connecting rod body 11 moves to the corresponding position, the second end 112 of the connecting rod body 11 can be smoothly snapped into the expansion assembly 3 under the elastic force of the elastic member body, realizing the preliminary connection of the first plate member 4 and the second plate member 5. At this time, the first plate member 4 and the second plate member 5 are in a loose state without being locked.

[0074] Specifically, in this embodiment, as Figure 5 shown, the elastic member body is a helical spring. Those skilled in the art can also set the elastic member body as an elastic structure such as a wave spring or a disc spring according to needs, and no further examples will be given here.

[0075] Specifically, in this embodiment, as Figure 4 and Figure 5 shown, the housing assembly includes two connecting rod housings 12 arranged in a buckled manner;

[0076] An elastic member installation groove is provided in the connecting rod housing 12. After the elastic member installation grooves of the two connecting rod housings 12 are buckled, a sealed cavity can be formed. The elastic member body and the limiting protrusion 115 are both located in the sealed cavity formed by the two elastic member installation grooves. The two connecting rod housings 12 arranged in a buckled manner provided in this embodiment can facilitate the installation of the elastic member body.

[0077] Specifically, in this embodiment, the cross-sectional shape of the connecting rod housing 12 is semi-circular. In some embodiments, those skilled in the art can also set the cross-sectional shape of the connecting rod housing 12 as any one or a combination of a C-shaped or U-shaped, and no further details will be given here.

[0078] Specifically, in this embodiment, as Figure 4 and Figure 5 shown, the two connecting rod housings 12 have the same structure, which can reduce the manufacturing cost of the connecting rod housing 12;

[0079] A number of housing connection lugs 122 are provided on one end face of the connecting rod housing 12, and a number of housing connection slots 123 are provided on the other end face;

[0080] The two connecting rod housings 12 are fixed by snapping together through the housing connection clamps 122 and the housing connection slots 123. Through snapping and fixing, the two connecting rod housings 12 can be snapped together to form a cylindrical housing assembly, which is convenient for installation. In some embodiments, bolt connection and other methods can also be used for connection. In some embodiments, ultrasonic welding and other methods can also be used to connect the two connecting rod housings 12 as a whole, which will not be repeated here.

[0081] In some embodiments, the two connecting rod housings 12 may also adopt different structures, as long as the elastic member body can be installed in the two connecting rod housings 12, and other shapes will not be given as examples here.

[0082] Specifically, in this embodiment, if Figure 4 and Figure 5 As shown, a first installation step 124 is provided at one end of the connecting rod housing 12 close to the second end head 112, so that the staff can judge whether the rod sleeve assembly 1 is knocked into place. In some embodiments, the connecting rod housing 12 can also be designed without the first installation step 124.

[0083] Specifically, in this embodiment, if Figure 1 , Figure 4 and Figure 5 As shown, the outer peripheral wall of the connecting rod housing 12 is also provided with an anti-slip thread to increase the connection friction between the housing assembly and the first plate 4 to prevent the rod sleeve assembly 1 from falling out after being installed in the first plate 4. In some embodiments, technicians can replace the anti-slip thread with a number of annular protrusion structures, which will not be given as examples here.

[0084] Specifically, in this embodiment, if Figure 4 and Figure 5 As shown, the sizes of the first end 111 and the second end 112 are both larger than the connecting rod body 11;

[0085] A first reduced diameter section is provided on one side of the first end 111 facing the housing assembly;

[0086] A second reduced diameter section is provided on a side of the second end 112 facing away from the housing assembly;

[0087] The first and second diameter-reducing sections are both in the direction from the first end 111 to the second end 112. By providing the first and second diameter-reducing sections, the first end 111 can be easily inserted into the rotating wheel 2, and the second end 112 can be easily inserted into the expansion assembly 3.

[0088] Specifically, in this embodiment, Figure 2 , Figure 4 and Figure 5The outer peripheral wall of the first reduced diameter section is curved, so that the rotating wheel 2 can pull the first end 111 more smoothly.

[0089] Specifically, in this embodiment, Figures 6 to 8 As shown, the expansion assembly 3 includes an embedded part 31 for being embedded and fixed in the plate, and an expansion sleeve 32 for being knocked into the plate and sleeved on the embedded part 31;

[0090] An expansion sleeve 32 is provided with an expansion seam 322 on one side close to the embedded part 31, and an expansion slope 311 is provided on the embedded part 31 for pushing the expansion sleeve 32 to expand its expansion seam 322. In this embodiment, when installing the expansion assembly 3, firstly, an embedded part installation hole 51 is opened on the second plate 5, and then the embedded part 31 is installed in the embedded part installation hole 51, and then the expansion sleeve 32 is installed on the embedded part 31. Since the embedded part 31 is provided with an expansion slope 311, the cross-sectional size of the embedded part 31 at the expansion slope 311 is larger than the inner circumferential wall size of the expansion sleeve 32, so it cannot be directly pushed by manpower. At this time, the expansion sleeve 32 is knocked with a tool to completely knock the expansion sleeve 32 into the embedded part 31. In the process of knocking in the expansion sleeve 32, the expansion slope 311 will press the inner circumferential wall of the expansion sleeve 32, so that the side of the expansion sleeve 32 with the expansion seam 322 expands in the peripheral direction, so that the expansion sleeve 32 is completely locked on the second plate 5.

[0091] Specifically, in this embodiment, Figures 6 to 9 As shown, a plurality of anti-slip annular protrusions 324 are arranged on the peripheral wall of the expansion sleeve 32. By arranging the anti-slip annular protrusions 324, the locking force between the expansion sleeve 32 and the second plate 5 after deformation can be improved to prevent the expansion sleeve 32 from slipping out. The cross-sectional shape of the anti-slip annular protrusion 324 in this embodiment can be a right-angled triangle, whose inclined surface is inclined downward, and one of the right-angled sides is arranged perpendicular to the peripheral wall of the expansion sleeve 32, so that the setting of the anti-slip annular protrusion 324 will not affect the knocking in of the expansion sleeve 32. At the same time, when the expansion sleeve 32 is pulled and tends to slip out, its right-angled side can form a blocking structure to prevent the expansion sleeve 32 from slipping out. Of course, in some embodiments, the cross-sectional shape of the anti-slip annular protrusion 324 can also be designed into an obtuse triangle, an acute triangle, or a rectangle, etc., which will not be given as examples here. In some embodiments, technicians can also replace the anti-slip annular protrusion 324 with an external thread or other anti-slip structure, which will not be repeated here.

[0092] Specifically, in this embodiment, Figures 6 to 9As shown, clamping ratchet protrusions 313 are provided on both sides of the embedded part 31, and a clamping ratchet groove 323 adapted to the clamping ratchet protrusion 313 is provided on the side of the expansion sleeve 32 close to the embedded part 31, so that after the expansion sleeve 32 is knocked onto the embedded part 31, the clamping ratchet protrusion 313 will be completely clamped into the clamping ratchet groove 323, thereby making the expansion sleeve 32 and the embedded part 31 completely clamped through the clamping ratchet protrusion 313 and the clamping ratchet protrusion 313.

[0093] Specifically, in this embodiment, Figures 6 to 9 As shown, the expansion sleeve 32 is provided with a waist-shaped through cavity 321 for installation on the embedded part 31;

[0094] An end guide plate 325 is disposed in a downwardly inclined manner in the oval through cavity 321 of the expansion sleeve 32;

[0095] The end of the expansion sleeve 32 away from the embedded part 31 is provided with a limiting step 326 for preventing the end from coming out, and the limiting step 326 is located obliquely above the end guide plate 325. By providing the inclined end guide plate 325, after the second end 112 moves to the expansion assembly 3, as the first plate 4 is moved, the entire connecting rod body 11 continuously moves toward the second end 112, and under the action of the elastic member body, the second end 112 will continue to press on the end guide plate 325 until the second end 112 moves below the limiting step 326. At this time, the first plate 4 and the second plate 5 only need to screw the rotating wheel 2 to be completely locked, and in this state, when the second plate 5 is moved to separate from the first plate 4, it is only necessary to overcome the elastic force of the elastic member body.

[0096] Specifically, in this embodiment, if Figure 8 and Fig. 9 As shown, one side of the top of the embedded part 31 is provided with a supporting inclined surface 312 for supporting the end guide plate 325, and the other side of the top of the embedded part 31 is provided with a horizontal end limit surface 314 to improve the support stability of the end guide plate 325;

[0097] The oval through cavity 321 of the expansion sleeve 32 is also horizontally provided with an end-positioning flat plate 327 connected to the bottom of the end guide plate 325;

[0098] When the expansion sleeve 32 is installed to the embedded part 31, the end limit surface 314 is located directly below the limit step 326, and the horizontal height is flush with or higher than the top surface height of the end-in-place plate 327, so that after the rotating wheel 2 is twisted to loosen the first plate 4 and the second plate 5, the second end 112 is pressed against the end limit surface 314 under the action of the elastic member or is in a naturally relaxed state and close to the end limit surface 314, and the horizontal height of the end limit surface 314 is flush with or higher than the top surface height of the end-in-place plate 327, which facilitates the second end 112 to move to the end-in-place plate 327 and the end guide plate 325 without being stuck, thereby preventing the second end 112 from being unable to move out of the expansion assembly 3.

[0099] Specifically, in this embodiment, if Figure 8 and Fig. 9 As shown, the side of the end guide plate 325 facing the limiting step 326 is concavely curved, which facilitates guiding the second end 112 .

[0100] Specifically, in this embodiment, if Figures 6 to 9 As shown, the cross-sectional shape of the expansion sleeve 32 is a gourd shape;

[0101] The cross-sectional shape of the embedded part 31 is a gourd shape that matches the cross-sectional shape of the expansion sleeve 32. In some embodiments, the cross-sectional shapes of the expansion sleeve 32 and the embedded part 31 can also be oval or other shapes, which will not be described in detail here.

[0102] Specifically, in this embodiment, if Figures 6 to 9 As shown, the cross-sectional shapes of the expansion sleeve 32 and the embedded part 31 are both gourd-shaped, which are formed by splicing two circles, one large and one small, to avoid the embedded part 31 from being installed in the wrong direction.

[0103] Specifically, in this embodiment, if Figures 6 to 8 As shown, a second installation step 315 is also provided at the bottom of the embedded part 31 to facilitate confirmation that the expansion sleeve 32 is installed in place.

[0104] Embodiment 2:

[0105] On the basis of the above-mentioned embodiment 1, Fig.10 As shown, this embodiment provides a connection method for a cabinet building block quick installation connection system as described above, comprising the following steps:
