[0038] Referring to Figure 1 and Figure 2 As shown, a connection component 100 of an embodiment of the present utility model is applied to an air handling unit 1000. The air handling unit 1000 includes a first box body 200 and a second box body 300. The first box body 200 and the second box body 300 are installed along a first direction. For example, the first direction is the Figure 1 up-and-down direction shown in the figure. Of course, the first direction can also be the front-back direction, the left-right direction, etc. In subsequent embodiments, the up-and-down direction is taken as an example for illustration. The first box body 200 is located below the second box body 300, or the first box body 200 is located above the second box body 300. One side of the first box body 200 is a first peripheral wall 210, and one side of the second box body 300 is a second peripheral wall 310. Taking the first box body 200 and the second box body 300 as square boxes as an example, the four side walls of the first box body 200 constitute the first peripheral wall 210, the four side walls of the second box body 300 constitute the second peripheral wall 310, and the first peripheral wall 210 and the second peripheral wall 310 are the outer side walls of the air handling unit 1000. For the convenience of description, in this embodiment, the first box body 200 is configured as a heat exchange box, and the second box body 300 is configured as a fan box.

[0039] Referring to Figure 3As shown, the connection assembly 100 includes a first connection member 110 and a second connection member 120. The first connection member 110 is fixedly connected to the outer side of the first peripheral wall 210 and is located at one end adjacent to the second box body 300 along the first direction, that is, the first connection member 110 is fixedly connected to one end of the first peripheral wall 210 close to the second box body 300. The first connection member 110 includes a first hook portion 111, which is bent toward the direction of the first peripheral wall 210 and extends in a direction away from the second box body 300. The second connection member 120 is fixedly connected to the outer side of the second peripheral wall 310 and is located at one end adjacent to the first box body 200 along the first direction, that is, the second connection member 120 is fixedly connected to one end of the second peripheral wall 310 close to the first box body 200. The second connection member 120 includes a second hook portion 121, which is bent toward the direction of the first peripheral wall 210 and extends in a direction close to the second box body 300. The second hook portion 121 is configured such that when the second box body 300 is installed on the first box body 200 , the second hook portion 121 is hooked with the first hook portion 111 , so that the second box body 300 is fixedly connected to the first box body 200 .

[0040] It is understandable that, by adopting the above solution, when the first box body 200 and the second box body 300 are stacked along the first direction, the second box body 300 and the first box body 200 can be fixedly connected by buckling the second hook 121 and the first hook 111. Since the first connecting member 110 and the second connecting member 120 are respectively located outside the first peripheral wall 210 and the second peripheral wall 310 instead of being located inside the air handling unit 1000, and the first connecting member 110 and the second connecting member 120 are located on the same side of the peripheral wall of the air handling unit 1000, the buckling operation of the first connecting member 110 and the second connecting member 120 is simple, which can reduce the difficulty of installation and improve the assembly efficiency.

[0041] Reference Figure 1 As shown, in the embodiment of the utility model, a plurality of connection components 100 are provided. For example, two connection components 100 are provided on the left wall and the right wall of the air handling unit 1000, respectively, to further improve the stability of the connection between the first box body 200 and the second box body 300.

[0042] Reference Figure 3As shown, in the embodiment of the present utility model, the second connecting member 120 further includes a base 122, a first rotating portion 123, and a second rotating portion 124. The base 122 is fixedly connected to the second peripheral wall 310. One end of the first rotating portion 123 is hinged to the base 122, and the hinged position is called the first hinge point 130. The second rotating portion 124 is hinged to the first rotating portion 123 and is spaced apart from the base 122. The position where the second rotating portion 124 is hinged to the first rotating portion 123 is called the second hinge point 140. The second hook portion 121 is provided at one end of the second rotating portion 124 away from the second hinge point 140. For example, the second hook portion 121 and the second rotating portion 124 are integrally formed, that is, one end of the second rotating portion 124 away from the second hinge point 140 is bent to form the second hook portion 121. Wherein, the second rotating portion 124 is configured such that when the second hook portion 121 cooperates with the first hook portion 111, it drives the first rotating portion 123 to rotate inward to lock the connecting assembly 100, or drives the first rotating portion 123 to rotate outward to unlock the connecting assembly 100.

[0043] It should be noted that, with reference to Figure 3 and Figure 4 As shown, the connection method of the first hinge point 130 can be: through holes are provided in both the base 122 and the first rotating portion 123, and a rotating shaft is passed through the through holes. Therefore, the first rotating portion 123 is hinged to the base 122 through the rotating shaft. Or a convex column is provided on the base 122, a through hole is provided on the first rotating portion 123, and the convex column is rotatably connected to the through hole. The connection method of the second hinge point 140 can be: the second rotating portion 124 is integrally formed with opposite and spaced rotating shafts, through holes are provided on both opposite sides of the second rotating portion 124, and the rotating shafts are rotatably matched with the through holes. Or through holes are provided on both opposite sides of the second rotating portion 124, rotating shafts are provided on both opposite sides of the first rotating portion and the second rotating portion 124, and the rotating shafts are rotatably matched with the through holes. Specifically, a suitable solution is selected according to the actual situation. The hinge mentioned in other embodiments can refer to the above connection methods and will not be described in detail herein.

[0044] It should also be noted that the first rotating portion 123 rotating inward means that the first rotating portion 123 rotates in the direction close to the base 122, such as Figure 3 the inward direction in Figure 3 . The first rotating portion 123 rotating outward means that the first rotating portion 123 rotates in the direction away from the base 122, such as the outward direction in Figure 3 . When it is necessary to fix the first box body 200 and the second box body 300, after the first hook portion 111 and the second hook portion 121 are buckled, the first rotating portion 123 or the second rotating portion 124 is pressed, thereby driving the second hook portion 121 to move and fixing the position of the second hook portion 121, so that the first hook portion 111 and the second hook portion 121 can be stably connected. Therefore, the connection method of the first connecting member 110 and the second connecting member 120 is simple and convenient.

[0045] Referring to Figure 3 As shown, in the first embodiment of the present utility model, one end of the second rotating part 124 is hinged to the middle part of the first rotating part 123. The middle part of the first rotating part 123 refers to the position of the first rotating part 123 between 1 / 3*h and 2 / 3*h, where h refers to the maximum length of the first rotating part 123. The first connecting piece 110 includes a lock handle part 125, and the lock handle part 125 is formed at one end of the first rotating part 123 away from the base 122. Among them, the lock handle part 125 and the second rotating part 124 are integrally formed, which can improve the assembly efficiency and connection stability; or they can also be connected by means of welding, clamping, fasteners, etc. The second connecting piece 120 is formed by bending a strip-shaped metal rod. The two ends of the metal rod are respectively hinged to the middle position of the first rotating part 123, and the middle part of the metal rod is bent to form a second hook part 121.

[0046] It can be understood that by adopting the above solution, when it is necessary to lock the first box body 200 and the second box body 300, first snap the second hook part 121 into the groove of the first hook part 111, and then press the lock handle part 125 to make the first rotating part 123 rotate inward, so as to drive the second hook part 121 to move upward through the second rotating part 124, and finally the second hook part 121 can be restricted from separating from the first hook part 111. When it is necessary to separate the second hook part 121 from the first hook part 111, just rotate the lock handle part 125 outward. Therefore, the operation of buckling or separating the second hook part 121 and the first hook part 111 is simple and convenient, and the disassembly and assembly efficiency is high.

[0047] Referring to Figure 4 As shown, in the second embodiment of the present utility model, one end of the first rotating part 123 away from the base 122 is hinged to the second rotating part 124. The second connecting piece 120 further includes a lock handle part 125, and the lock handle part 125 is arranged at one end of the second rotating part 124 close to the hinge. Among them, the second connecting piece 120 is formed by stamping a sheet metal part. For example, one end of the second connecting piece 120 is bent to form a second hook part 121, and the other end of the second connecting piece 120 is integrally formed with a lock handle part 125, which can improve the assembly efficiency and connection stability. As an alternative embodiment, the lock handle part 125 and the second hook part 121 can also be connected to the second connecting piece 120 by means of welding, clamping, fasteners, etc.

[0048] It can be understood that by adopting the above solution, when it is necessary to lock the first box body 200 and the second box body 300, first snap the second hook portion 121 into the groove of the first hook portion 111, and then press the lock handle portion 125, so that the second connecting member 120 drives the first connecting member 110 to rotate inward. Therefore, the second connecting member 120 will move upward and cause the second hook portion 121 and the first hook portion 111 to be clamped tightly to prevent the second hook portion 121 from disengaging from the first hook portion 111. When it is necessary to disengage the second hook portion 121 from the first hook portion 111, just rotate the lock handle portion 125 outward. Therefore, the operation of buckling or separating the second hook portion 121 and the first hook portion 111 is simple and convenient, and the disassembly and assembly efficiency is high.

[0049] Referring to Figure 5 and Figure 6 As shown, in the third embodiment of the present invention, the second connecting member 120 further includes a second bottom plate 126 and a connecting arm 127. The second bottom plate 126 is plate-shaped and fixedly connected to the second peripheral wall 310. One end of the connecting arm 127 is fixedly connected to the lower end of the second bottom plate 126 through an inclined plate 128, and the other end of the connecting arm 127 is bent to form the second hook portion 121. Wherein, the inclined plate 128 and the second bottom plate 126 are arranged at an angle, and the angle is less than 90°, so that the connecting arm 127 and the second peripheral wall 310 are spaced apart, which is beneficial to the buckling of the second hook portion 121 and the first hook portion 111, and can reduce the materials required for the second connecting member 120. Among them, the second bottom plate 126 is fixedly connected to the second peripheral wall 310 through fasteners, and the fasteners can be screws, bolts, pins, pin shafts, etc. Taking screws as an example, during installation, the fasteners are passed through the second bottom plate 126 and threadedly connected to the second peripheral wall 310, so as to effectively fix the position of the second bottom plate 126 and improve the stability and reliability of the connection. When disassembly is required, just unscrew the screw. By adopting the scheme of connecting with fasteners such as screws and bolts, the cost of the connecting component 100 is relatively low, and the installation reliability is high.

[0050] Referring to Figure 7As shown, in the fourth embodiment of the present utility model, the second connecting member 120 further includes a second bottom plate 126 and a connecting arm 127. The second bottom plate 126 is plate-shaped and fixedly connected to the second peripheral wall 310. One end of the connecting arm 127 is fixedly connected to the upper end of the second bottom plate 126 through a straight plate 129, and the other end of the connecting arm 127 is bent to form a second hook portion 121. Among them, the included angle between the inclined plate 128 and the second bottom plate 126 is 90°, so that the connecting arm 127 and the second peripheral wall 310 are arranged at intervals, which is beneficial to the buckling connection between the second hook portion 121 and the first hook portion 111. Among them, the second bottom plate 126 is fixedly connected to the second peripheral wall 310 through fasteners, and the fasteners can be screws, bolts, pins, pin shafts, etc. Taking screws as an example, during installation, the fasteners are passed through the second bottom plate 126 and threadedly connected to the second peripheral wall 310, so as to effectively fix the position of the second bottom plate 126 and improve the stability and reliability of the connection. When disassembly is required, just unscrew the screw. The scheme of connecting with fasteners such as screws and bolts has a lower cost of the connecting component 100 and high installation reliability.
