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. The spring is a flexible part, which is prone to fatigue failure and entanglement after long-term use, affecting efficiency and increasing costs. In addition, 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 costs and improve assembly efficiency while making the base connection more secure is a problem that researchers are currently concerned about. Summary of the invention

[0004] The problem solved by the present invention is how to make the connection of air-conditioning components more firmly while reducing the cost and improving the 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 a first component and a second component of an 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 cooperated with the connecting part 1 to be formed in one step, and is used to connect the second component; an elastic band 3, which connects the connecting part 1 and the hook structure 2, and is used to generate an elastic force so that the hook structure 2 fastens the second component.

[0006] Thus, the elastic force generated by the elastic band is utilized to enable the hook structure to fasten the second component, thereby preventing the hook structure from coming out, thereby making the connection of the air-conditioning components more secure; the air-conditioning connecting device is formed in one step, and there is no need to assemble the hook structure and the connecting part when connecting the air-conditioning, thereby improving the assembly efficiency.

[0007] Optionally, the thickness of the elastic band 3 is not less than 0.8 mm.

[0008] This ensures that the elastic band has a longer service life.

[0009] Optionally, the elastic band 3 is in the shape of a straight plate, a folded line or a wavy line.

[0010] Therefore, when the elastic band is a broken line or a wavy line, the total length of the elastic band is increased, so that the hook structure has a larger movement stroke, ensuring that the hook structure can fasten the second component.

[0011] Optionally, the length of the elastic band 3 is 40 mm±30%, and the width of the elastic band 3 is 15 mm±30%.

[0012] Optionally, the fitting between the connecting portion 1 and the hook structure 2 is a clearance fit, and the movable clearance of the clearance fit is not less than 0.5 mm.

[0013] Thereby, the hook structure is prevented from being stuck, so that the hook structure has better movement flexibility and the connection performance is improved.

[0014] Optionally, the height difference between the connecting portion 1 and the hook structure 2 is no more than 8 mm.

[0015] Thereby, the appearance of the air conditioning connection device is ensured to be smooth, and a good visual effect is ensured after the air conditioning components are connected.

[0016] Optionally, the device further comprises: a rib 4, which is arranged at the bottom matching position of 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 rib 4 breaks.

[0017] Optionally, the number of the ribs 4 is one or more.

[0018] Thus, the ribs enable the hook structure and the connecting portion to be formed and prepared in one step, and are easily broken when the air conditioner is connected, so that the hook structure can move relative to the connecting portion.

[0019] Optionally, the elastic band 3 is made of ABS plastic, HIPS, POM or steel sheet.

[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. 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 air conditioner connecting device is described by taking the first component and the second component as the lower base and the upper base of the air conditioner respectively as an example. The left and right sides of the lower base and the upper base of the air conditioner should be connected through the air conditioner connecting device in this embodiment.

[0031] like Figure 1 As shown, the air conditioner connection device includes a connection part 1, a hook structure 2 and an elastic band 3. 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, thereby 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 0.5mm, so as to prevent the hook structure 2 from getting stuck, thereby ensuring that the hook structure 2 can move relative to the connection part 1, such as Figure 2 shown.

[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 to achieve the nesting 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 1 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 certain range. The above 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] A space is formed between the connecting portion 1 and the hook structure 2, and the elastic band 3 is arranged in the space, and the two ends of the elastic band 3 are respectively connected to the connecting portion 1 and the hook structure 2, and the elastic band 3 can generate elastic force, so that the hook structure 2 fastens the second component. In this embodiment, for example, the top end surface of the hook structure 2 is pressed to drive the elastic band 3 to move toward the bottom of the hook structure 2, so that the elastic band 3 generates elastic deformation, and the elastic force generated by the elastic deformation is the force that moves the hook structure 2 toward the top. When the top end surface of the hook structure 2 is released, the elastic force drives the hook structure 2 to move toward the top, so that the hook structure 2 fastens the second component.

[0037] The thickness of the elastic band 3 is not less than 0.8 mm to prevent the elastic band 3 from being too thin and affecting its service life.

[0038] The shape of the elastic band 3 is a straight plate, a folded line or a wavy line. When the elastic band 3 is a straight plate-shaped elastic band, the air conditioning connection device formed is as follows Figure 1 When the elastic band 3 is a folded line or wavy line elastic band, the air conditioning connection device formed is as shown Figure 4 When the elastic band 3 is a broken line or a wavy line, the total length of the elastic band 3 is increased while the strength of the elastic band 3 remains substantially unchanged, thereby increasing the maximum movement stroke of the hook structure 2 and ensuring that the hook structure 2 can fasten the second component.

[0039] The length of the elastic band 3 is 40 mm ± 30%, and the width of the elastic band 3 is 15 mm ± 30%. By setting the length and width of the elastic band 3, the elastic force generated by the elastic band 3 can be ensured to meet the requirements, while the service life of the elastic band 3 is increased and the operation is convenient for users.

[0040] The elastic band 3 is made of acrylonitrile butadiene styrene (ABS) plastic, high impact polystyrene (HIPS), polyformaldehyde (POM) or steel sheet. The above materials can increase the maximum stress that the elastic band 3 can withstand, have higher reliability, and also have higher safety.

[0041] The height difference between the connection part 1 and the hook structure 2 formed by one molding is not more than 8mm. Further, the connection part 1, the hook structure 2 and the elastic band 3 are formed by one molding, and the height difference between the connection part 1, the hook structure 2 and the elastic band 3 is not more than 8mm. The height difference between the connection part 1, the hook structure 2 and the elastic band 3 in the direction perpendicular to their installation surface should not be too large to ensure the smooth appearance of the air conditioner connection device. After the air conditioner connection device connects the first component and the second component of the air conditioner, the air conditioner as a whole has a good visual effect.

[0042] In this embodiment, the air conditioner connection device further includes a 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 rib 4 breaks. The number of ribs 4 is one or more. When the number of ribs 4 is one, the 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 ribs 4 is more than one, the more than one ribs 4 are circumferentially distributed at the bottom connection between the connection part 1 and the hook structure 2, such as Figure 3 shown.

[0043] See also Figure 3 The ribs 4 are composed of very small thin ribs. When the connection part 1 and the hook structure 2 are processed, the ribs 4 connect 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 that is nested with each other when they are formed, which is convenient for injection molding. In addition, the ribs 4 are easy to break. When the ribs 4 are subjected to external force, the ribs 4 break under the action of the external force, thereby releasing the connection between the connection part 1 and the hook structure 2, so that the hook structure 2 can move relative to the connection part 1.

[0044] 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.

[0045] In this embodiment, a handle 6 can also be provided on the connection part 1, and the connection part 1, the hook structure 2, the elastic band 3 and the handle 6 are formed in one piece. The handle 6 is provided to facilitate the operator to use the air conditioner connection device to connect the first component and the second component of the air conditioner.

[0046] 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 process of connecting the base of the air conditioner connecting device is described. In this embodiment, the connecting part 1, the hook structure 2, the elastic band 3, the rib 4, the fixing hole 5, and the handle 6 are all one-time formed structures, and the hook structure 2 can move relative to the connecting part 1. First, the air conditioner connecting device is fixed to the lower base of the air conditioner through the fixing hole 5 on the connecting part 1; then, the top end face of the hook structure 2 is pressed so that the hook structure 2 contacts and enters the upper base of the air conditioner, and the elastic band 3 is deformed and generates an elastic force, which can make the hook structure 2 move in the direction of fastening the upper base of the air conditioner, and the rib 4 breaks during the movement of the hook structure 2; finally, the top end face of the hook structure 2 is released, and the hook structure 2 moves in the direction of fastening the upper base of the air conditioner under the action of the above-mentioned elastic force, and fastens the upper 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.

[0047] In this embodiment, the connecting part and the hook structure connecting the two components are arranged as a nested and one-step formed structure, and the hook structure and the connecting part are connected by an elastic band. The elastic force generated by the elastic band is used to make the hook structure fasten the second component to prevent the hook structure from falling out, so that the connection of the air-conditioning components is more firmly established. In addition, there is no need to assemble the hook structure and the connecting part when connecting the air-conditioning components, which improves the assembly efficiency and reduces the cost of connecting the air-conditioning components.

[0048] 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.

[0049] To sum up, the air-conditioning connecting device provided in the embodiment of the present invention sets the connecting part and the hook structure connecting the two components as a nested and one-step formed structure, and connects the hook structure and the connecting part through an elastic band. The elastic force generated by the elastic band is used to enable the hook structure to fasten the second component to prevent the hook structure from falling out, so that the connection of the air-conditioning components is more firmly established. In addition, there is no need to assemble the hook structure and the connecting part when connecting the air-conditioning components, which improves the assembly efficiency and reduces the cost of connecting the air-conditioning components. Setting the elastic band to a broken line or wavy line shape can increase the maximum movement stroke of the hook structure, ensure that the hook structure can fasten the second component, and improve the connection effect.

Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention.
