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.

[0003] It can be seen that how to reduce costs 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 reduce the cost while making the connection of air-conditioning components more firmly.

[0005] To solve the above problems, the present invention provides an air-conditioning connecting device on one hand, for connecting a first component and a second component of an air-conditioning, the device comprising: a connecting part 1, for connecting the first component; a hook structure 2, nested with the connecting part 1, for connecting the second component; a first elastic band 3, connected to the connecting part 1; a second elastic band 4, connected to the hook structure 2, the first elastic band 3 and the second elastic band 4 partially overlap to generate an elastic force, so that the hook structure 2 fastens the second component.

[0006] Thus, the elastic force generated by the two separate elastic bands is used to enable the hook structure to fasten the second component to prevent the hook structure from coming out, thereby making the connection of the air conditioning components more secure, and the separate elastic bands can reduce the stress on them and increase their service life.

[0007] Optionally, the relationship between the length of the overlapping portion of the first elastic band 3 and the second elastic band 4 and the movement stroke of the hook structure 2 is: 0.5L<h<4L, wherein h is the length of the overlapping portion, and L is the movement stroke.

[0008] Therefore, the length of the overlapping portion of the two separate elastic bands can meet the movement requirements of the hook structure without causing inconvenience in operation due to being too long.

[0009] Optionally, the thickness of the first elastic band 3 and the second elastic band 4 is 1 mm-2.5 mm.

[0010] This ensures that the discrete elastic bands have a longer service life.

[0011] Optionally, the number of the first elastic band 3 and the second elastic band 4 is one or two.

[0012] Therefore, the number of elastic bands can be set according to the material of the elastic bands, so that the elastic bands have a wider range of material applications.

[0013] Optionally, the connecting portion 1 and the hook structure 2 are nested and formed in one step.

[0014] Optionally, the connecting portion 1 and the hook structure 2 are detachably connected.

[0015] Therefore, the discrete elastic band can be used in the one-time formed connection part and the hook structure, and can also be used in the detachably connected connection part and the hook structure, thereby ensuring the application scope of the discrete elastic band.

[0016] Optionally, the fit 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.

[0017] Thereby, the hook structure is prevented from being stuck, so that the hook structure has better movement flexibility and the connection performance is improved.

[0018] Optionally, the height difference between the connecting portion 1 and the hook structure 2 is no more than 8 mm.

[0019] 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.

[0020] Optionally, the first elastic band 3 and the second elastic band 4 are made of ABS plastic, HIPS, POM or steel sheet.

[0021] 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.

[0022] 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 2-3 ,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, a first elastic band 3 and a second elastic band 4. The hook structure 2 is nested with the connection part 1, and the hook structure 2 can move relative to the connection part 1. The connection part 1 is used to connect the first part of the air conditioner, and the hook structure 2 is used to connect the second part of the air conditioner. A space is formed between the connection part 1 and the hook structure 2, and the first elastic band 3 and the second elastic band 4 are arranged in the space. The first elastic band 3 connects the connection part 1, and the second elastic band 4 connects the hook structure 2. The first elastic band 3 and the second elastic band 4 partially overlap to generate elastic force, so that the hook structure 2 fastens the second part.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] In this embodiment, for example, by pressing the top end surface of the hook structure 2, the second elastic band 4 is driven to move toward the bottom of the hook structure 2, and the second elastic band 4 contacts the first elastic band 3, so that both the first elastic band 3 and the second elastic band 4 are elastically deformed. Figure 3 As shown, the elastic force generated by the elastic deformation is the force that causes the hook structure 2 to move 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.

[0036] The relationship between the length of the overlapping portion of the first elastic band 3 and the second elastic band 4 and the movement stroke of the hook structure 2 is:

[0037] 0.5L<h<4L

[0038] Wherein, h is the length of the overlapping portion of the first elastic band 3 and the second elastic band 4, and L is the movement stroke of the hook structure 2. Specifically, the movement stroke L of the hook structure 2 is, for example, 7.6 mm, and the length h of the overlapping portion of the first elastic band 3 and the second elastic band 4 is, for example, 15 mm. Ensuring that the length of the overlapping portion of the two separate elastic bands meets the movement requirements of the hook structure can prevent the overlapping portion from being too short and causing misalignment failure, and can also prevent the overlapping portion from being too long and requiring the user to apply a large pressing force, thereby ensuring the connection effect and facilitating user operation.

[0039] The thickness of the first elastic band 3 and the second elastic band 4 is 1 mm-2.5 mm. Limiting the thickness of the elastic band to 1 mm-2.5 mm can prevent the elastic band from being too thin and causing a short life, and can also prevent the elastic band from being too thick and requiring the user to apply a large pressing force, thereby ensuring the life of the air conditioner connection device and facilitating user operation.

[0040] The number of the first elastic band 3 and the second elastic band 4 is one or two. Specifically, the number of the first elastic band 3 and the second elastic band 4 is set according to the material of the elastic band. When the hardness of the material is relatively large (such as steel sheets), two first elastic bands 3 are superimposed together, and two second elastic bands 4 are superimposed together to form a discrete elastic band, and the total thickness of the two superimposed elastic bands is 1mm-2.5mm; when the hardness of the material is relatively small (such as plastic), the number of the first elastic band 3 and the second elastic band 4 is one, and the thickness of this elastic band is 1mm-2.5mm.

[0041] The first elastic band 3 and the second elastic band 4 are 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 can withstand, have higher reliability, and also have higher safety.

[0042] In this embodiment, the connecting portion 1 and the hook structure 2 are nested and formed in one step, or the connecting portion 1 and the hook structure 2 are detachably connected.

[0043] When the connection part 1 and the hook structure 2 are nested and formed at one time, the connection part 1, the hook structure 2, the first rib 3, and the second rib 4 are all formed at one time. One-time molding includes one-piece molding, or multiple parts assembled together in a mold at one time. For example, in this embodiment, the hook structure 2 and the connection part 1 can be assembled together after one-time molding. For example, the connection part 1 and the hook structure 2 are nested together using a mold molding processing method, the first elastic band 3 is connected to the connection part 1, and the second elastic band 4 is connected to the hook structure 2, and one-time molding forms an integral structure that can move relative to each other. It can be understood that other processing methods can also be used to nest the connection part 1, the hook structure 2, the first rib 3, and the second rib 4 together for one-time molding, and the processing method is not limited in this embodiment. When the air conditioner connection device is used to connect two parts of the air conditioner, it is not necessary to assemble the connection part 1 and the hook structure 2, which saves the process of installing the connection part 1 and the hook structure 2 to each other, thereby improving the assembly efficiency.

[0044] When the connection between the connecting part 1 and the hook structure 2 is detachable, the first rib 3 and the connecting part 1 can be molded at one time, and the second rib 4 and the hook structure 2 can be molded at one time. When connecting the second component and the first component of the air conditioner, the connecting part 1 and the hook structure 2 can be nested and installed together.

[0045] The height difference between the connection part 1 and the hook structure 2 is not greater than 8 mm. Further, the height difference between the connection part 1, the hook structure 2, the first elastic band 3 and the second elastic band 4 is not greater than 8 mm. The height difference between the connection part 1, the hook structure 2, the first elastic band 3 and the second elastic band 4 in the direction perpendicular to their installation surface should not be too large to ensure that the appearance of the air conditioner connection device is smooth. 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.

[0046] The air conditioner connection device further comprises a fixing hole 5, which is arranged in the connection part 1 and is used to fix the connection part 1 on the first component, thereby ensuring a firm connection between the connection part 1 and the first component.

[0047] A handle 6 may also be provided on the connecting portion 1 to facilitate an operator to connect the second component and the first component of the air conditioner using the air conditioner connecting device.

[0048] Taking the case where the first component is the lower base of the air conditioner and the second component is the upper base of the air conditioner as an example, the process of connecting the base of the air conditioner connecting device is described. 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 second elastic band 4 follows the hook structure 2 to move in the direction close to the first elastic band 3. When the second elastic band 4 overlaps with the first elastic band 3, the two elastic bands are deformed and generate elastic force, which can make the hook structure 2 move in the direction of fastening the upper base of the air conditioner; 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 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.

[0049] In this embodiment, a connecting part is used to connect the first component of the air conditioner, and a hook structure is used to connect the second component of the air conditioner. The second component and the first component are respectively connected to an elastic band. The elastic force generated by the two discrete elastic bands is used to enable the hook structure to fasten the second component to prevent the hook structure from falling out, thereby making the connection of the air conditioner components more secure. The discrete elastic band can reduce the stress it is subjected to and increase its service life. The discrete elastic band can be used in a structure in which the connecting part and the hook structure are formed at one time, and can also be used in a detachable connecting part and the hook structure. The discrete elastic band has a wide range of applications.

[0050] This embodiment also provides an air conditioner, including: Figure 1-Figure 3The 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.

[0051] To sum up, the air conditioning connecting device provided in the embodiment of the present invention utilizes a connecting part to connect the first component of the air conditioner, utilizes a hook structure to connect the second component of the air conditioner, and the second component and the first component are respectively connected to an elastic band. The elastic force generated by the two discrete elastic bands is used to enable the hook structure to fasten the second component to prevent the hook structure from falling out, thereby making the connection of the air conditioning components more firmly, and the discrete elastic band can reduce the stress it is subjected to and increase its service life. The discrete elastic band can be used in a structure in which the connecting part and the hook structure are formed at one time, and can also be used in a detachable connecting part and the hook structure, and has a wider range of applications.

[0052] 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.
