[0042] Figure 1 is a schematic structural diagram of a connection structure according to an embodiment of the present utility model, asFigure 1 as shown in and with reference to Figures 2 to 5 An embodiment of the present utility model provides a connection structure, including a connection plate 100 and a buckle 200.

[0043] A process hole 110 is provided on the connection plate 100.

[0044] The buckle 200 includes a connection part 220 and a hook 210. One end of the connection part 220 is fixedly connected to the hook 210, and the other end of the connection part 220 is fixedly connected to the hole wall of the process hole 110. The hook 210 is spaced outside the first plate surface 130 of the connection plate 100.

[0045] The connection plate 100 and the buckle 200 are integrally formed. In the projection on the first plate surface 130, the buckle 200 is within the process hole 110, and the hook 210 and the connection part 220 do not interfere with each other.

[0046] In this embodiment, the hook 210 is spaced outside the first plate surface 130 of the connection plate 100. That is to say, the hook 210 is outside the process hole 110 and is spaced from the connection plate 100. Among them, the first plate surface 130 is a surface of the connection plate 100.

[0047] The connection plate 100 and the buckle 200 are of an integrally formed structure. During the forming process of the connection plate 100 and the buckle 200, the mold can pass through the process hole 110 to form the surface of the buckle 200, which not only reduces the difficulty of mold design but also reduces the number of molds, thereby reducing the mold opening cost of the connection structure and further achieving the purpose of reducing the production cost of the connection structure.

[0048] Moreover, during the demolding process, compared with the buckle 200 with a complex structure, the buckle 200 of the present utility model can be demolded by using the process hole 110, which reduces the demolding difficulty of the buckle 200 and the connection plate 100, improves the production efficiency of the connection structure, and achieves the purpose of reducing the production cost of the connection structure.

[0049] In some embodiments of the present utility model, taking the connection part 220 being vertically arranged as an example.

[0050] The surface of the buckle 200 away from the connection part 220 is inclined from top to bottom towards the outside of the buckle 200.

[0051] The surface of the hook 210 close to the connection part 220 is not inclined from top to bottom towards the direction close to the connection part 220.

[0052] The surface of the connection part 220 close to the hook 210 is not inclined from top to bottom towards the direction close to the hook 210.

[0053] In this embodiment, on the side of the hook 210 close to the connecting portion 220, forming and demolding can be directly completed by using a mold structure through the process hole 110, which avoids adding structures such as inclined top sliders in the mold, further saves the mold opening cost, and at the same time improves the demolding efficiency.

[0054] In some embodiments of the present utility model, such as Figure 3 or Figure 5 As shown, a support portion 221 extending along the first plate surface 130 is formed at the bottom of the connecting portion 220, and the support portion 221 is fixedly connected to the hole wall of the process hole 110.

[0055] Furthermore, in some embodiments of the present utility model, the height of the support portion 221 along the axial direction of the process hole 110 is the same as the hole depth of the process hole 110, so as to avoid interference between the support portion 221 and the mounting plate 300 during the installation process of the connection structure, and even affect the installation of the connection structure.

[0056] In some embodiments of the present utility model, such as Figure 3 As shown, both ends of the support portion 221 are fixedly connected to the hole wall of the process hole 110.

[0057] Furthermore, the support portion 221 is rod-shaped, and both ends in the length direction of the support portion 221 are fixedly connected to the hole wall of the process hole 110.

[0058] In this embodiment, both ends of the support portion 221 in its extending direction are connected to the hole wall of the process hole 110, so as to improve the structural strength of the buckle 200, reduce the situation of the buckle 200 falling off during use, and improve the quality of the connection structure.

[0059] In some embodiments of the present utility model, such as Figure 3 As shown, the process hole 110 is a round hole. The support portion 221 extends along the radial direction of the round hole.

[0060] In this embodiment, during the production and manufacturing process, the round hole is more convenient for forming and demolding, improves the production efficiency of the buckle 200, and thus reduces the production cost. The support portion 221 extends along the radial direction of the process hole 110 and is connected to the hole wall of the process hole 110, so that the support portion 221 is on the center line of the process hole 110 and evenly separates the process hole 110, avoiding the situation that the gap on one side of the support portion 221 is too small, resulting in difficult forming or demolding.

[0061] In some embodiments of the present utility model, in the projection on the first plate surface 130, the hook 210 is arc-shaped, and the hook 210 is coaxially arranged with the process hole 110.

[0062] In this embodiment, the outer surface of the hook 210 is arc-shaped, which avoids scratching the user and improves the user experience. Moreover, the arc-shaped surface of the hook 210 can make the surface of the hook 210 smoother, facilitating the engagement of the buckle 200 into the buckle hole 310.

[0063] The hook 210 is coaxially arranged with the process hole 110, that is, the buckle 200 is located at the center of the process hole 110. The coaxial arrangement of the hook 210 and the process enables the hook 210 to better disperse stress when subjected to external forces, reducing local stress concentration and thus enhancing the stability of the buckle 200.

[0064] In some embodiments of the present utility model, such as Figure 3 or Figure 5 as shown, the buckle 200 includes two oppositely arranged hooks 210.

[0065] In this embodiment, the setting of the two hooks improves the stability of the connection structure after installation.

[0066] In some embodiments of the present utility model, such as Figure 3 or Figure 5 as shown, one end of the buckle 200 away from the connecting plate 100 is conical.

[0067] In this embodiment, the conical end of the buckle 200 is inserted into the buckle hole 310 so that the buckle 200 is engaged on one side of the buckle hole 310. The buckle hole 310 cooperating with the buckle 200 is usually a circular hole, making the process of inserting the buckle 200 into the buckle hole 310 simpler. The conical design enables the buckle 200 to gradually reduce the contact area with the buckle hole 310 during the insertion process, thereby reducing the insertion resistance and making the operation smoother. After being fully inserted, the bottom of the buckle 200 has a relatively large contact surface to increase the connection strength and stability between the connection structure and the mounting plate 300.

[0068] Moreover, the conical structure facilitates mold opening and demolding, reducing the production cost.

[0069] In some embodiments of the present utility model, on the projection of the first plate surface 130, the extending direction of the hook 210 is perpendicular to the support portion 221.

[0070] In this embodiment, the hook 210 extends in a direction perpendicular to the support portion 221 to play a guiding role when the buckle 200 is inserted into the buckle hole 310, thereby improving the installation efficiency of the buckle 200.

[0071] In some embodiments of the present utility model, when the buckle 200 is inserted into the buckle hole 310, there is a gap between the hook 210 and the first plate surface 130 that can at least accommodate the mounting plate 300 in the state where the hook 210 rotates towards the connecting portion 220, so as to prevent the mounting plate 300 from affecting the movement of the hook 210.

[0072] In some embodiments of the present utility model, as Figure 1 or Figure 2 shown, there are multiple process holes 110 arranged at intervals, and the buckle 200 is correspondingly arranged with the process holes 110.

[0073] In this embodiment, there are multiple process holes 110 provided on the connecting plate 100. The multiple process holes 110 correspond to multiple buckles 200. The design of the multiple buckles 200 avoids the rotation of the connection structure when the connection structure is installed on the mounting plate 300, thereby improving the stability of the connection structure.

[0074] Preferably, there are two process holes 110, and the two process holes 110 are located at both ends of the diagonal line of the connecting plate 100 to improve the installation stability of the connection structure after the connection structure is installed on the mounting plate 300.

[0075] In some embodiments of the present utility model, as Figure 1 or Figure 2 shown, a first connection hole 120 is provided on the connecting plate 100.

[0076] In this embodiment, when installing the connection structure on the mounting plate 300, first use the buckle 200 to be clamped on the mounting plate 300 for fixation to form a preliminary fixation. Then, pass through the first connection hole 120 and use fasteners to fix the connection structure on the mounting plate 300 to simplify the operation process.

[0077] In some embodiments of the present utility model, as Figure 2 shown, the first connection holes 120 are multiple and arranged at intervals.

[0078] Some embodiments of the present utility model also provide an electrical box. In some embodiments of the electrical box of the present utility model, as Figure 1 shown, the electrical box includes the connection structure in any of the above embodiments and a side plate 400. The side plate 400 is fixedly connected to the periphery of the connecting plate 100 and is integrally injection-molded with the connection structure.

[0079] In this embodiment, the side plate 400 and the connection structure are integrally injection-molded to improve the molding efficiency of the electrical box, reduce the production time, and improve the production efficiency of the electrical box. Since the buckle 200 is provided on the connection structure, the buckle 200 is formed and demolded through the process hole 110, which simplifies the structure of the mold for forming the connection structure and the side plate 400, reduces the mold opening cost of the integrally formed connection structure and side plate 400, and thus achieves the purpose of reducing the production cost of the electrical box.

[0080] Moreover, during the demolding process, compared with the buckle 200 with a complex structure, the buckle 200 of the present invention can be demolded by using the process hole 110, reducing the demolding difficulty of the buckle 200 and the connection plate 100, improving the production efficiency of the connection structure, and achieving the purpose of reducing the production cost of the connection structure.

[0081] The embodiment of the present invention also provides an air conditioner. In some embodiments of the air conditioner of the present invention, the air conditioner includes the electrical box, the mounting plate 300, and the casing in any one of the above embodiments.

[0082] An air conditioner computer board is installed in the electrical box. A first connection hole 120 is provided on the connection plate 100.

[0083] A buckle hole 310 is provided on the mounting plate 300, and the buckle hole 310 is correspondingly arranged with the buckle 200. A second connection hole corresponding to the first connection hole 120 is provided on the mounting plate 300, and the second connection hole is aligned with the first connection hole 120.

[0084] The mounting plate 300 is fixedly connected to the casing.

[0085] In this embodiment, when installing the electrical box, first snap the buckle 200 into the buckle hole 310 to pre-fix the electrical box on the mounting plate 300, meeting the requirement that the user can fix the electrical box on the mounting plate 300 with a fastener with one hand. The fastener is preferably a fastening screw.

[0086] The electrical box is an integrally formed structure. During the forming process of the connection plate 100 and the buckle 200, the mold can pass through the process hole 110 to form the surface of the buckle 200 close to the process hole 110, which not only reduces the difficulty of mold design but also reduces the number of molds, reduces the mold opening cost of the connection structure, and thus achieves the purpose of reducing the production cost of the air conditioner.

[0087] Moreover, during the demolding process, the buckle 200 of the present invention can be demolded by using the process hole 110, reducing the demolding difficulty of the buckle 200 and the connection plate 100, improving the production efficiency of the connection structure, and achieving the purpose of reducing the production cost of the connection structure.

[0088] Moreover, due to the small volume and precise structure of the electrical box, the forming process of the connection structure is complex. The structures of the buckle 200 and the connecting plate 100 in the present utility model reduce the forming and demolding difficulties of the electrical box.

[0089] Up to this point, those skilled in the art should recognize that although multiple exemplary embodiments of the present utility model have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present utility model can still be directly determined or derived based on the content disclosed in the present utility model without departing from the spirit and scope of the present utility model. Therefore, the scope of the present utility model should be understood and determined to cover all these other variations or modifications.
