They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0055] In the description of the present invention, "several" means one or more, "many" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself. The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0056] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0057] Reference Figures 1 to 3 The connecting assembly includes a connecting block 110, a connecting rod 120 and a locking piece 130. One end of the connecting rod 120 is set on the connecting block 110, and the other end is inserted into the support rod 200. The locking piece 130 can penetrate the support rod 200 and press the peripheral side of the connecting rod 120. The connecting block 110 presses the support rod 200. Specifically, the connecting block 110 and the connecting rod 120 can be detachably threaded. The purpose is to disassemble the connecting assembly first for easy packaging and transportation. The connecting block 110 and the connecting rod 120 are connected. The rod 120 can also be an integrally molded setting, which reduces the assembly steps and the number of parts, facilitates customer installation and reduces production costs. It should be noted that the support rod 200 is provided with a through hole or a blind hole that can accommodate the connecting rod 120. The outer diameter of the connecting rod 120 can be matched with the clearance of the through hole or the blind hole to prevent the connecting block 110 from shaking on the support rod 200 or the connecting block 110 from tilting and pressing the support rod 200. It should be understood that the circumferential side of the connecting rod 120 can be the circumferential side surface of the connecting rod 120.

[0058] In some embodiments, a through hole that can accommodate a locking piece 130 can be opened on the side wall of the support rod 200, and the locking piece 130 can pass through the through hole to press the side wall of the connecting rod 120. The locking piece 130 can be an interference fit or a transition fit with the through hole. After one end of the connecting rod 120 is fixed to the connecting block 110, the connecting rod 120 is inserted into the support rod 200, and then the locking piece 130 is passed through the through hole to press the side wall of the connecting rod 120. The friction between the locking piece 130 and the connecting rod 120 can limit the up and down movement of the connecting rod 120.

[0059] In some embodiments, a threaded hole that cooperates with the locking member 130 can also be opened on the support rod 200, that is, the locking member 130 can be a locking screw or a bolt, and the locking member 130 can be threaded into the support rod 200 and the end of the locking member 130 contacts or presses the circumferential side of the connecting rod 120, thereby locking the connecting rod 120 in the support rod 200. This process can be achieved by limiting the relative movement of the two through the mutual friction between the end of the locking member 130 and the surface of the connecting rod 120. It should be understood that the pressing of the circumferential surface of the connecting rod 120 by the locking member 130 can play a certain fixing role.

[0060] In some embodiments, the locking member 130 can be inserted into the support rod 200 and crimped with the inclined portion on the peripheral side of the connecting rod 120. Specifically, the locking member 130 can be inserted from the through hole on the support rod 200, and the end of the locking member 130 can be crimped with the inclined portion on the peripheral side of the connecting rod 120. That is, the locking member 130 abuts the inclined portion so that the connecting rod 120 is subjected to a force toward the inside of the support rod 200, so that the connecting block 110 can press the support rod 200, ensuring that the connecting block 110 is stably crimped on one end of the support rod 200.

[0061] Reference Figures 1 to 3 In some embodiments, an annular groove 14 may be provided on the connecting rod 120, and the locking piece 130 is pressed against the side wing of the annular groove 121 relatively away from the connecting block 110. It should be understood that the side wing here can be the inclined portion on the circumferential side of the connecting rod 120. In this embodiment, the annular groove 121 can be directly processed on the connecting rod 120, and the locking piece 130 penetrates the support rod 200 and can press against the side wing of the annular groove relatively away from the connecting block 110, thereby providing a pulling force for the connecting block 110 to move toward the support rod 200, ensuring that the connecting block 110 presses the support rod 200; it should be noted that when the connecting rod 120 is inserted into the support rod 200, on the axis of the support rod 200, the maximum distance of the locking piece 130 relative to the connecting block 110 can be less than the distance of the annular groove relative to the connecting block 110. The farthest distance, that is, the locking piece 130 penetrates into the support rod 200 and the outer wall of the locking piece 130 and the side wings of the annular groove can be interference connected, that is, they will be crimped; further, the side wings on the annular groove 121 that are crimped with the locking piece 130 are arranged obliquely, that is, the locking piece 130 penetrates into the support rod 200 and the end of the locking piece 130 is crimped with the obliquely arranged side wings. At this time, the crimping force of the locking piece 130 relative to the horizontal crimping connecting rod 120 is divided into a horizontal crimping force and a tensioning force along the axis of the support rod 200 toward the direction away from the connecting block 110 at the contact point between the two, ensuring that the connecting block 110 is always subjected to the tensioning force when connected to the support rod 200, thereby improving the connection stability of the connecting block 110 and the support rod 200, and avoiding loosening of the connecting block 110 and the support rod 200 after long-term use.

[0062] In some embodiments, the connecting rod 120 may also be provided with a connecting portion 412 that contacts the end of the locking member 130. The connecting portion 412 is inclined outward along the axis of the connecting rod 120 away from the connecting block 110. It should be understood that the connecting portion 412 here can be an inclined portion on the circumferential side of the corresponding connecting rod 120. It can be understood that there is such an inclined portion corresponding to the side wing on the circumferential side of the connecting rod 120 to cooperate with the locking member 130 to fix the connecting rod 120 in the support rod 200, and enable the connecting block 110 and the support rod 200 to be crimped, and is not limited to the form of the side wing in the annular groove 121. The connecting portion 412 is preferably an annular inclined surface included on the bushing. The connecting portion 412 can be fixed to the connecting rod 120 by welding, integral molding, etc. The locking member 130 crimps the connecting portion 412 relatively close to one end of the connecting block 110 to pull the connecting block 110 to press the support rod 200.

[0063] It should be understood that the annularly arranged flanks or inclined portions facilitate installation of the connecting rod 120 , i.e., there is no need to pre-position the circumferential position of the inclined portion during engagement of the locking member 130 with the inclined portion, making installation more convenient.

[0064] Reference Figure 2 In some embodiments, the connection assembly may further include a sleeve 140 fixedly installed in the support rod 200, the sleeve 140 may be welded and fixed to the support rod 200, a threaded hole is provided on the side wall of the sleeve 140, and an external thread matching the threaded hole is provided on the locking member 130, that is, the locking member 130 may be a locking screw, and after the locking member 130 is inserted into the support rod 200 and threadedly connected to the sleeve 140, the end of the locking member 130 is pressed against the connecting rod 120, the purpose of which is that the material requirements of the support rod 200 are higher and the material requirements of the sleeve 140 are lower, the support rod 200 may be tubular or the outer wall of the support rod 200 may be thin enough to be welded to the sleeve 140, and there is no need to open a threaded hole, thereby reducing the weight or tube thickness of the support rod 200, improving the applicability of the connection assembly, and the sleeve 140 may be made of lightweight material.

[0065] In some embodiments, there can be two symmetrically arranged locking members 130. The purpose is that the two locking members 130 can offset each other's horizontal pressure relative to the connecting rod 120, avoid uneven force on the connecting rod 120 in the support rod 200, and at the same time increase the tensioning force to further ensure that the connecting block 110 presses the support rod 200.

[0066] In some embodiments, the support rod 200 can be in the shape of a circular tube or a polygonal tube, the connecting rod 120 can be in the shape of a circle or a polygon, and the through hole or blind hole on the support rod 200 that matches the connecting rod 120 is also configured as a circular hole or a square hole.

[0067] In some embodiments, the connection block 110 may be in the shape of a sphere, a cube, a cone, or a frustum.

[0068] Reference Figure 12 The bracket includes the above-mentioned connecting assembly. Furthermore, at least two connecting rods 120 are provided on the connecting assembly. The bracket adopts several support rods 200 to be connected in sequence or staggered to form a frame or rack shape. The bracket stably connected by the connecting assembly is easy to assemble. One end of the connecting rod 120 is fixed to the connecting block 110, and the other end is inserted into the support rod 200. The connecting rod 120 is fixed in the support rod 200 by the locking member 130 to ensure the stable connection of the bracket. No pre-installation operations such as welding are required, which facilitates the packaging and transportation of components such as the support rod 200 and the connecting assembly 100.

[0069] Reference Figure 13 The table includes a main body, table legs 810 and a table top 820. The main body can be a bracket formed by splicing the connecting component 100 and the support rod 200. The table legs 810 can also be stably spliced ​​at the lower end of the bracket through the connecting component 100. The upper end cover of the bracket is provided with a table top 820. The table assembled using the connecting component 100 has the advantages of easy assembly, stable connection, and is not easy to loosen even after long-term use.

[0070] Reference Figure 14 The sofa includes a sofa frame and a seat cushion 910 and a back cushion 920 laid on the sofa frame. The sofa frame can be assembled by splicing several connecting components 100 and several brackets. The sofa can be assembled by placing the seat cushion 910 and the back cushion 920 on the sofa frame. It is convenient and fast, the connection is stable, and it is not easy to loosen after long-term use.

[0083] Reference Figures 4 to 7 In some embodiments, the clamping member 420 is L-shaped, the inner side of the L-shape is used to clamp the corresponding support plate 300, and the outer side of the L-shape is used to connect the corresponding support rod 200.

[0084] Reference Figure 10 and Figure 11In some embodiments, the cabinet further includes a maintaining mechanism, which is used to maintain the door panel 500 in a closed state and to maintain the door panel 500 at a predetermined opening angle. That is, when the door lock 600 is opened, the maintaining mechanism can also keep the door panel 500 closed; after the door panel 500 is opened to a predetermined angle, the maintaining mechanism can keep the door panel 500 at the predetermined angle, so that the door panel 500 does not sag or pitch. Preferably, the maintaining mechanism is designed as a passive mechanism without power or energy, and is designed as a multi-link structure, in which when two adjacent links are folded or unfolded on the same straight line, the multi-link structure maintains a triangle, utilizing the natural law of triangle stability.

[0085] Reference Figure 16 In some embodiments of the present invention, the connecting block 110 connecting two adjacent support rods 200 in the cabinet body is cylindrical and extends in the vertical direction, that is, the axial direction of the cylinder is in the vertical direction. Unlike spherical connecting blocks, the axial end of the cylindrical connecting block is relatively flat, and the connecting block is more stable when connecting to the support rods and serving as a support foot, and the assembled cabinet is less likely to be skewed or uneven. The side panels of the adjacent two-layer structure of the cabinet can be a single piece of board, saving material costs and labor manufacturing and assembly costs. When assembling cabinets using this connecting assembly, the gaps between the cabinet panels and the door are very small, and the cabinet also has a better appearance.

[0086] In some embodiments of the present invention, a door panel 500 is further included, and the door panel 500 is hingedly connected to a corresponding vertically extending support rod 200. The cabinet door panel is hingedly connected to the vertical support rod, and the cabinet door panel is similar to a cantilever beam. The axial end of the cylindrical connecting block is relatively flat, and the connecting block is relatively stable when connected to the support rod and serves as a support foot. Even under the pendant force of the cantilever beam, the cabinet is not easily tilted.

[0087] Reference Figure 17 In some embodiments of the present invention, a lamp 1010 is mounted on one of the support rods of the cabinet. The lamp 1010 is electrically connected to one end of a cable 1020. The other end of the cable 1020 is electrically connected to a plug 1030 and / or a USB port 1040. The cable 1020 passes through a portion of the support rod 200, a portion of the connecting rod 120, and a portion of the connecting block 110. The support rod 200, the connecting rod 120, and the connecting block 110 through which the cable 1020 passes are provided with threading holes. It is understood that in some cases, a single cable of sufficient length may not be available, so the cable 1020 may be assembled from multiple sections.

[0088] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the scope of the present invention.
