Description

Technical Field

[0001] This utility model relates to the field of cabinet technology, and in particular to a connecting buckle and a combination cabinet. Background Technology

[0002] To make it easier for users to assemble, some existing cabinets are designed with lighter panels and simpler connectors between components.

[0003] like Figure 1 As shown, Figure 1 The existing modular cabinet mainly includes cabinet panels 1 and connecting buckles 2. The connecting buckles 2 are located between four cabinet panels 1, and the four cabinet panels 1 are on the same plane. The cabinet panels 1 are composed of steel bars 11 and sheet material 12 covering the steel bars 11. The connecting buckles 2 are provided with arc-shaped opening slots to lock the steel bars 11 into the slots to realize the connection between the cabinet panels 1.

[0004] However, during the actual installation process, it was found that due to the low manufacturing precision of the connecting clip 2, some of the arc openings of the clip slots were too large, which could easily cause the reinforcing bars to loosen after being clipped. In addition, some of the arc clips of the clip slots were too small, making it difficult to insert the reinforcing bars, which made the installation more troublesome. Utility Model Content

[0005] To address the shortcomings of existing technologies, a connecting clip that facilitates user connection of cabinet panels is provided.

[0006] This utility model is achieved by the following technical solution: a connecting buckle, comprising:

[0007] A positioning buckle includes a base plate, one side of which is provided with a plurality of limiting grooves for fixing a cabinet panel extending along a first direction; and a fixing buckle that cooperates with the positioning buckle, located on the other side of the base plate, wherein a space is formed between the fixing buckle and the positioning buckle for fixing a cabinet panel extending along a second direction, the second direction being perpendicular to the first direction; a coupling structure is provided between the positioning buckle and the fixing buckle to realize their assembly and disassembly, the coupling structure including a coupling member extending along the first direction and a coupling groove that cooperates with the coupling member;

[0008] When the coupling component mates with the coupling groove, it can drive the fixing buckle to move toward the positioning buckle side, so that the two have sufficient clamping force to fix the cabinet panel located between them.

[0009] When using the aforementioned connecting clips, the user can place several cabinet panels extending in the second direction between the positioning clip and the fixing clip. The fixing clip then connects to the positioning clip, moving towards the positioning clip to provide sufficient clamping force to secure the cabinet panels between them, thus completing the fixation of the cabinet panels in the second direction. For fixing the cabinet panels in the first direction, the cabinet panels extending in the first direction can be inserted into the limiting groove.

[0010] The coupling component and the coupling groove can be coupled by means of threaded engagement, plug-in engagement, magnetic fixation, etc.

[0011] The first direction can be along the front and back of the cabinet, and the second direction can be along the left and right of the cabinet; or the first direction can be along the left and right of the cabinet, and the second direction can be along the front and back of the cabinet.

[0012] This solution uses fasteners and positioning clips to clamp the cabinet panels, thus avoiding problems such as loosening of the cabinet panels or difficulties in installation caused by low manufacturing precision of the connecting clips.

[0013] Preferably, the sidewalls of the fixing buckle and / or positioning buckle are provided with a plurality of first limiting protrusions, which are used to pre-position the corner of the cabinet panel and restrict the cabinet panel from sliding along the second direction.

[0014] The steel bars at the corners of the cabinet panel are approximately right angles. The first limiting protrusion is located inside the steel bar, which can restrict the sliding of the cabinet panel and further ensure the firmness of the fixed cabinet panel. At the same time, the first limiting protrusion can also pre-position the corners of the steel bar.

[0015] Preferably, the substrate is provided with a plurality of limiting plates, which together form the limiting groove. The limiting plates have a flipping structure or a chamfered structure at the inlet of the limiting groove. The groove wall of the limiting plate is provided with a second limiting protrusion, which is used to engage the cabinet panel to prevent the cabinet panel from coming out of the limiting groove.

[0016] The diameter of the inlet of the limiting groove can be increased by using a chamfered or folded structure, which facilitates the insertion of the cabinet panel. By setting a second limiting protrusion on the groove wall of the limiting groove, the cabinet panel extending in the first direction can be limited.

[0017] Preferably, the circumferential sidewall of the coupling member is provided with a clearance angle for avoiding the corner of the steel reinforcement in the cabinet panel.

[0018] The avoidance angle can both avoid the corners of the steel bars and provide a pre-position for the cabinet panels, so that the position of the connected cabinet panels is accurate and the overall appearance is guaranteed.

[0019] Preferably, the coupling member is disposed on the positioning buckle and has a plurality of coupling portions extending radially thereon. The coupling groove is disposed on the fixing buckle and includes an entry groove and a locking groove. The entry groove extends along a first direction and allows the coupling portions to enter. The locking groove communicates with the entry groove and is located on the rotation path of the coupling portion. The locking groove is used to restrict the movement of the coupling portion along the first direction.

[0020] After the coupling part of the coupling component enters the inlet groove, the fixing buckle is rotated, causing the coupling part to move from the inlet groove into the locking groove. The coupling part is misaligned, thereby achieving the connection between the fixing buckle and the positioning buckle. The rotation axis of the coupling part is along the first direction.

[0021] Preferably, the locking groove has a head end and an end end along its length direction, the head end is connected to the entry groove, and the end end is provided with an abutment portion that limits the rotation stroke of the fixing buckle; there is a height difference between the head end and the end end, and when the coupling portion is located at the end end, the fixing buckle moves toward the positioning buckle side.

[0022] The abutment part prevents the fixing buckle from rotating too far, and the height difference between the first and last ends ensures that the fixing buckle moves towards the positioning buckle after rotation, allowing it to clamp the cabinet panel securely with the positioning buckle. This height difference refers to the fact that the first and last ends are not on the same horizontal or height plane.

[0023] Preferably, a raised portion is provided on the groove wall at the end of the locking groove, and the raised portion cooperates with the abutment portion to restrict the relative rotation of the positioning buckle and the fixing buckle.

[0024] When the retaining buckle rotates in the positive direction until its end abuts against the contact part, the retaining buckle and the positioning buckle are fully coupled. By setting the raised part, the retaining buckle can be prevented from rotating in the opposite direction, thereby limiting the relative rotation between the positioning buckle and the retaining buckle.

[0025] Preferably, the positioning buckle is provided with the coupling member, the fixing buckle is provided with the coupling groove, and the coupling member and the coupling groove are threadedly engaged.

[0026] The positioning buckle and the fixing buckle are coupled by means of threaded connection. At the same time, when the fixing buckle is screwed on, the fixing buckle can move towards the positioning buckle side to clamp the cabinet panel.

[0027] Preferably, the positioning buckle is provided with the coupling member, and the fixing buckle is provided with the coupling groove. The coupling member and the coupling groove can be inserted to achieve a tight fit.

[0028] The positioning buckle and the fixing buckle are fixed by plugging and clamping, and can also be used to clamp the cabinet panel.

[0029] A modular cabinet with the aforementioned connecting clips includes several cabinet panels, wherein the cabinet panels at least at their non-corner locations are connected by the aforementioned connecting clips.

[0030] The cabinet panels at non-corner locations are the most difficult to install, so the aforementioned connecting clips make it easier to install these panels.

[0031] Compared with the prior art, this utility model uses a fixing buckle and a positioning buckle to clamp the cabinet panel to fix the cabinet panel, which has the advantage of avoiding the problem of the cabinet panel becoming loose or difficult to install due to the low manufacturing precision of the connecting buckle.

[0042] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0043] Example 1

[0044] like Figure 2 and Figure 3 As shown, this embodiment 1 discloses a connecting buckle and a modular cabinet. The modular cabinet includes several cabinet panels 1. Each cabinet panel 1 is composed of rectangular steel bars 11 and sheets 12 covering the steel bars 11. The sheets 12 can be made of existing plastic materials. The steel bars 11 are set at approximately 90° at the corners of the cabinet panels 1. The connecting buckle 2 can connect the steel bars at the corners of the cabinet panels 1.

[0045] In this embodiment 1, the first direction is the front-to-back direction of the cabinet in the figure, and the second direction is the left-to-right direction of the cabinet in the figure.

[0046] like Figures 3 to 9 As shown, the connecting buckle 2 includes a positioning buckle 21 and a fixing buckle 22 that cooperate with each other. The positioning buckle 21 includes a base plate 211. One side of the base plate 211 is provided with four limiting plates 212 extending along a first direction. Each limiting plate 212 is right-angled, and the four limiting plates 212 are arranged in a cross shape to form four limiting grooves 4. The limiting grooves 4 are used to engage the corners of the cabinet panel 1 extending along the first direction. Two of the limiting grooves 4 in the figure have a folding structure 2121 on the limiting plate 212. The folding structure 2121 is that the limiting plate 212 is folded in a direction away from the inlet side, so that the diameter of the inlet of the limiting groove 4 is larger to facilitate the insertion of the cabinet panel 1. The limiting plate 212 of the limiting groove 4 can also have a chamfered structure at the inlet of the limiting groove 4 (not shown in the figure) to make the diameter of the inlet of the limiting groove 4 larger to facilitate the insertion of the cabinet panel 1.

[0047] The limiting plate 212 also has a second limiting protrusion 2122. The second limiting protrusion 2122 has gaps on both sides to allow it to deform and thus engage the corner of the reinforcing bar 11 of the cabinet panel 1. The second limiting protrusion 2122 can also take other shapes, such as hemispherical or arc-shaped. The two limiting grooves 4 have wavy protrusions inside, all for better engagement of the cabinet panel 1.

[0048] The fixing buckle 22 is located on the other side of the positioning buckle 21, forming a gap extending in the second direction between them for clamping the cabinet panel 1 extending in the second direction. The fixing buckle 22 is petal-shaped or cross-shaped to facilitate rotation by the user. The fixing buckle 22 and the positioning buckle 21 have a coupling structure, which includes a coupling member 31 disposed on the positioning buckle 21. The coupling member 31 extends from the positioning buckle 21 side to the fixing buckle 22 side. The end of the coupling member 31 near the fixing buckle 22 has two radially outwardly extending coupling portions 311, and the two coupling portions 311 are arranged radially symmetrically.

[0049] Four avoidance angles 51 are provided on the circumferential sidewall of the coupling member 31 to avoid the corners of the steel bars 11 of the cabinet plate 1. A first limiting protrusion 5 corresponding to the avoidance angles 51 is provided on the end face of the other side of the positioning buckle 21.

[0050] The fixing buckle 22 has a coupling groove 32 that mates with the coupling member 31. The coupling groove 32 includes an inlet groove 321 and a locking groove 322, both in the shape of a straight line. The inlet groove 321 extends along a first direction and allows the coupling part 311 to enter. The locking groove 322 communicates with the inlet groove 321 and is located on the rotation path of the coupling part 311. The locking groove 322 is used to restrict the movement of the coupling part 311 along the first direction. The locking groove 322 is generally quarter-circular in shape and has a head end and an end end. The head end connects to the inlet groove 321, and the end end has an abutment part 61, which in this embodiment is the wall of the fixing buckle 22. There is a height difference between the head end and the end end. Figure 9 Taking the coordinates in the figure as an example, the height of the end is higher than the height of the beginning. The end also has a raised portion 62, and a space is formed between the raised portion 62 and the abutment portion 61 to restrict the fixing buckle 22 from rotating in the positive or negative direction.

[0051] Example 2

[0052] The difference between Embodiment 2 and Embodiment 1 is that the coupling member 31 in Embodiment 2 has an external thread structure, and the coupling groove 32 has an internal thread structure. The threaded engagement between the coupling member 31 and the positioning buckle 21 is achieved by rotating the fixing buckle 22. (Not shown in the figure)

[0053] Example 3

[0054] The difference between Embodiment 3 and Embodiment 1 is that in Embodiment 3, the coupling member 31 and the coupling groove 32 are tightly fitted together by plugging in. (Not shown in the figure)

[0055] In the use of Embodiment 1, for the cabinet panel 1 extending along the second direction, the corner of the cabinet panel 1 is first pre-positioned by the first limiting protrusion 5. Then, the fixing buckle 22 is sleeved on the coupling member 31, so that the coupling member 31 enters the groove 321. Then, the fixing buckle 22 is rotated so that the coupling member 31 is located in the locking groove 322. At this time, the fixing buckle 22 will move towards the positioning buckle 21 to clamp the cabinet panel 1, thereby completing the fixing of the cabinet panel 1. For the cabinet panels at the corners of the combination cabinet, the cabinet panel 1 extending along the first direction can be inserted into the limiting groove 4 to complete the fixing.
