Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air conditioning connecting device and an air conditioner. Background Art

[0002] The base parts of the air conditioner are very complex parts. In order to demold and assemble the mold, the base of the air conditioner is divided into an upper base and a lower base, and the upper base and the lower base need to be connected. In the related art, the connection assembly includes two independent parts: a handle and a connection block. First, the spring is installed into the connection block, and then the connection block is put into the handle. Then the handle is fixed on the lower base, and the connection block is inserted into the lower base. The connection block moves relative to the handle under the action of the spring, so that the hook on the connection block enters the upper base, and the upper and lower bases are locked under the elastic force of the spring. However, the spring, connection block, and handle need to be assembled, and there are many assembly processes, which affects efficiency.

[0003] It can be seen that how to reduce the assembly process when connecting the base and improve the assembly efficiency is a problem that researchers are currently concerned about. Summary of the invention

[0004] The problem solved by the present invention is how to reduce the assembly process during air conditioner connection and improve assembly efficiency.

[0005] In order to solve the above problems, the present invention provides an air-conditioning connecting device on one hand, which is used to connect the first component and the second component of the air-conditioning, and the device includes: a connecting part 1, which is used to connect the first component; a hook structure 2, which is nested and matched with the connecting part 1 and is formed in one step, and is used to connect the second component, and the length of the part of the hook structure 2 that forms a nested fit with the connecting part 1 is greater than the movement stroke of the hook structure 2.

[0006] Thus, the air-conditioning connecting device is formed in one step, and the air-conditioning components do not need to be assembled when connected, thereby improving the assembly efficiency. The length of the nested matching part is greater than the movement stroke, thereby preventing the hook structure from falling off.

[0007] Optionally, the hook structure 2 includes: a connecting block 21, both ends of which are nested with the connecting portion 1; and a hook 22, which is arranged on the connecting block 21 and is used to connect the second component.

[0008] Optionally, the nested fit is a clearance fit.

[0009] Optionally, the active clearance of the clearance fit is not less than 0.5 mm.

[0010] Thereby, it is ensured that the connecting block can be pressed from both ends, so that the hook structure fastens the second component, thereby improving the connection performance.

[0011] Optionally, the movement range of the hook structure 2 is within a preset range.

[0012] Thereby, it is ensured that the hook structure can fasten the second component, and the size of the device is prevented from increasing due to the excessive length of the nested matching part.

[0013] Optionally, the height difference between the connecting portion 1 and the hook structure 2 is no more than 8 mm.

[0014] Thereby, the appearance of the air conditioner connecting device is ensured to be smooth, and a good visual effect is ensured after the components are connected.

[0015] Optionally, the device further comprises: a first rib 3 , disposed between the connecting portion 1 and the hook structure 2 , and used for connecting the connecting portion 1 and the hook structure 2 .

[0016] Therefore, the first ribs allow better plastic fluidity during the injection molding process, facilitating one-step molding of the connecting portion and the hook structure.

[0017] Optionally, the device further comprises: a second rib 4, which is arranged at the bottom connection between the connecting part 1 and the hook structure 2, and is used to connect the connecting part 1 and the hook structure 2. When the hook structure 2 moves relative to the connecting part 1, the second rib 4 breaks.

[0018] Optionally, the number of the second ribs 4 is one or more.

[0019] Thus, the second rib enables the hook structure and the connecting portion to be formed and prepared in one step, and is easily broken when the components are connected, so that the hook structure can move relative to the connecting portion.

[0020] Another aspect of the present invention provides an air conditioner, comprising the air conditioner connecting device as described above, wherein the air conditioner connecting device is used to connect the upper base and the lower base of the air conditioner.

[0021] The advantages of the air conditioner and the above-mentioned air conditioner connecting device over the prior art are the same, which will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0029] This embodiment provides an air conditioner connecting device, which is used to connect a first component and a second component of an air conditioner. Figure 1 This is a schematic diagram of the structure of an air conditioner connection device provided by an embodiment of the present invention. Figure 1 , while combining Figure 2-4 ,right Figure 1 The structure shown is described in detail.

[0030] In this embodiment, the application scenario of the air conditioner connection device is described by taking the first component and the second component as an example, the lower base of the air conditioner and the upper base of the air conditioner, respectively. The left and right sides of the lower base of the air conditioner and the upper base of the air conditioner should be connected by the air conditioner connection device in this embodiment. It can be understood that the air conditioner connection device can also be used in other structures with connection requirements.

[0031] like Figure 1 As shown, the air conditioner connection device includes a connection part 1 and a hook structure 2, the connection part 1 and the hook structure 2 are nested and formed at one time, and the hook structure 2 can move relative to the connection part 1, the connection part 1 is used to connect the first component, and the hook structure 2 is used to connect the second component. The length of the part of the hook structure 2 that forms a nested fit with the connection part 1 is greater than the movement stroke of the hook structure 2, thereby ensuring that the hook structure 2 will not be separated from the connection part 1 during the movement process, ensuring the reliability of the connection of the air conditioner components. The first component is, for example, the lower base of the air conditioner, and the second component is, for example, the upper base of the air conditioner.

[0032] One-time molding includes one-piece molding, or multiple parts that are assembled together in a mold at one time. For example, in this embodiment, the hook structure 2 and the connecting part 1 can be assembled together after being molded at one time. Specifically, for example, the connecting part 1 and the hook structure 2 are nested together using a mold molding processing method, and a one-time molding is formed to form an integral structure that can move relative to each other, such as nesting the connecting shafts at both ends of the hook structure 2 in the connecting part 1. It can be understood that other processing methods can also be used to nest the connecting part 1 and the hook structure 2 together, and the processing method is not limited in this embodiment. When the air-conditioning connecting device is used to connect two parts of the air conditioner, there is no need to assemble the connecting part 1 and the hook structure 2, which eliminates the process of installing the connecting part 1 and the hook structure 2 to each other, thereby improving the assembly efficiency.

[0033] The hook structure 2 includes a connection block 21 and a hook 22. The two ends of the connection block 21 are nested with the connection part 1. The hook 22 is arranged on the connection block 21 and is used to connect the second component. The nested fit between the hook structure 2 and the connection part 1 is a clearance fit, that is, a clearance fit is formed between the two ends of the connection block 21 and the connection part 1, and the movable gap between the two is not less than 0.5 mm. Figure 2 As shown, the hook structure 2 is prevented from getting stuck, thereby ensuring that the hook structure 2 can move relative to the connecting part 1.

[0034] In this embodiment, for example, the two ends of the connection block 21 are set as connection shafts, and holes matching the connection shafts are set in the connection part 1, and the connection shafts and the holes are nested and matched, so as to realize the nesting and matching of the hook structure 2 and the connection part 1. Furthermore, a movable gap is set between the connection shaft and the hole, and the connection shafts at both ends of the connection block 21 can be pressed to make the hook structure 2 move relative to the connection block 21 under the action of external force, and the hook structure 2 will not be stuck. The movement stroke of the hook structure 2 is less than the length of the connection shaft at either end, so as to ensure that the hook structure 2 will not fall off from the connection part 1.

[0035] The movement stroke of the hook structure 2 is within a preset range. The preset range can be determined according to the specific size of the connection portion between the hook structure 2 and the second component, and no specific restrictions are made here. Controlling the movement stroke of the hook structure 2 within a certain range can not only ensure that the hook structure 2 will not be unable to fasten the second component due to a too small movement stroke, but also avoid the problem of the hook structure 2 increasing the size of the air conditioner connection device due to an excessively long movement stroke.

[0036] The height difference between the connection part 1 and the hook structure 2 formed by one molding is not greater than 8 mm. Specifically, the height difference between the connection part 1 and the hook structure 2 in the direction perpendicular to the mounting surface thereof should not be too large to ensure a smooth appearance of the air conditioning connection device. After the air conditioning connection device connects the first component and the second component, the first component, the second component and the air conditioning connection device as a whole have a good visual effect.

[0037] In this embodiment, the air conditioner connection device further includes a first rib 3, which is disposed between the connection portion 1 and the hook structure 2 and is used to connect the hook structure 2 and the connection portion 1. Figure 3 It can be seen that a space is formed between the connecting part 1 and the hook structure 2, and the first rib 3 is arranged in the space and connects the hook structure 2 and the connecting part 1. The first rib 3 allows better plastic fluidity during the injection molding process, facilitates the one-time molding of the connecting part 1 and the hook structure 2, and improves the preparation efficiency and preparation quality of the air-conditioning connecting device. It is understandable that when the first rib 3 is not provided between the connecting part 1 and the hook structure 2, the connecting part 1 and the hook structure 2 can still be formed in one molding; or, after the connecting part 1, the hook structure 2 and the first rib 3 are formed in one molding, the first rib 3 can be cut off to prevent the first rib 3 from preventing the relative movement between the hook structure 2 and the connecting part 1.

[0038] In this embodiment, the air conditioner connection device further includes a second rib 4, which is used to connect the hook structure 2 and the connection part 1, so that the connection part 1 and the hook structure 2 are nested and formed at one time, and when the hook structure 2 moves relative to the connection part 1, the second rib 4 breaks. The number of the second ribs 4 is one or more. When the number of the second ribs 4 is one, the second rib 4 is arranged at the bottom connection between the connection part 1 and the hook structure 2 to connect the hook structure 2 and the connection part 1 from the bottom; when the number of the second ribs 4 is more than one, the more than one second ribs 4 are circumferentially distributed at the bottom connection between the connection part 1 and the hook structure 2, such as Figure 4 shown.

[0039] See also Figure 4 The second rib 4 is composed of very small thin ribs. When the connection part 1 and the hook structure 2 are processed, the second rib 4 connects the hook structure 2 and the connection part 1 from the bottom, so that the connection part 1 and the hook structure 2 are an integral structure nested with each other when they are formed, which is convenient for injection molding. In addition, the second rib 4 is easy to break. When the second rib 4 is subjected to external force, the second rib 4 breaks under the action of the external force, thereby releasing its connection with the connection part 1 and the hook structure 2, so that the hook structure 2 can move relative to the connection part 1.

[0040] In this embodiment, the air conditioner connecting device further comprises a fixing hole 5, which is arranged in the connecting part 1 and is used to fix the connecting part 1 on the first component, thereby ensuring a firm connection between the connecting part 1 and the first component.

[0041] In this embodiment, a handle 6 may be further provided on the connection part 1, and the connection part 1, the hook structure 2, the first rib 3 and the handle 6 are formed in one piece. The handle 6 is provided to facilitate operators to connect air conditioner components using the air conditioner connection device.

[0042] Taking the first component as the lower base of the air conditioner and the second component as the upper base of the air conditioner as an example, the connection process of the air conditioner connection device is described. In this embodiment, the connection part 1, the hook structure 2, the first rib 3, the second rib 4, the fixing hole 5, and the handle 6 are all one-time molding structures. Before using the air conditioner connection device to connect the upper base of the air conditioner and the lower base of the air conditioner, first cut the first rib 3 so that the hook structure 2 can move relative to the connection part 1, and fix the air conditioner connection device on the lower base of the air conditioner through the fixing hole 5 on the connection part 1, the hook structure 2 contacts and connects the upper base of the air conditioner, and then presses the bottom end face of the hook structure 2 so that the hook structure 2 moves in the direction of buckling the upper base of the air conditioner, the second rib 4 breaks during the movement of the hook structure 2, and the hook structure 2 buckles the upper base of the air conditioner, thereby stably connecting the upper base of the air conditioner and the lower base of the air conditioner. When it is necessary to release the connection between the upper base and the lower base of the air conditioner, press the top end surface of the hook structure 2 to make the hook structure 2 move in the direction of separating from the upper base of the air conditioner, thereby releasing the connection between the hook structure 2 and the upper base of the air conditioner, and then remove the air conditioning connecting device from the lower base of the air conditioner through the fixing hole 5.

[0043] In the present embodiment, the connecting part and the hook structure connecting the two components of the air conditioner are arranged as a nested and one-step formed structure, so that there is no need to assemble the hook structure and the connecting part when the air conditioning components are connected, thereby improving the assembly efficiency, and the length of the part of the hook structure that nests with the connecting part is greater than the movement stroke of the hook structure, thereby preventing the hook structure from falling off the connecting part, ensuring the stability of the assembly, and reducing the cost of the air conditioner connection.

[0044] This embodiment also provides an air conditioner, including: Figure 1-Figure 4 The air conditioner connecting device in the embodiment shown has an upper base and a lower base that can be detachably connected, and the air conditioner connecting device is used to connect the upper base and the lower base of the air conditioner. The air conditioner and the air conditioner connecting device have the same advantages over the prior art. For details not covered in this embodiment, please refer to the previous embodiment, which will not be repeated here.

[0045] To sum up, the air-conditioning connecting device and the air-conditioner provided in the embodiments of the present invention arrange the connecting part and the hook structure connecting the two components of the air-conditioning as a structure that is nested and matched and formed in one step, so that there is no need to assemble the hook structure and the connecting part when the air-conditioning components are connected, thereby improving the assembly efficiency and reducing the cost; the length of the part of the hook structure that is nested and matched with the connecting part is greater than the movement stroke of the hook structure, thereby preventing the hook structure from falling off the connecting part and ensuring the stability of the assembly; the connecting part and the hook structure can be connected by a first rib, which facilitates the one-time molding of the connecting part and the hook structure, thereby improving the preparation efficiency and preparation quality of the device.

[0046] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
