Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to a base connection 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 base connection more firmly.

[0005] In order to solve the above problems, the present invention provides a base connecting device on one hand, which is used to connect a first base and a second base, and the device includes: a connecting part 1, which is used to connect the first base; a hook structure 2, which is detachably connected to the connecting part 1, and is used to connect the second base; a travel limiter 3, which abuts against the hook structure 2 to prevent the hook structure 2 from falling out in the direction of separating from the second base.

[0006] Therefore, the travel limiter is used to abut against the hook structure to prevent the hook structure from coming out, so that the base connection is more secure, and the travel limiter will not cause fatigue failure or entanglement due to long-term use, which effectively reduces the cost.

[0007] Optionally, the travel limiter 3 is a wedge-shaped block provided with an inclined side surface, and the inclined side surface of the wedge-shaped block abuts against the hook structure 2 to push the hook structure 2 to move in a direction of fastening the second base.

[0008] Optionally, the number of the inclined side surface of the wedge block is one, so as to push the hook structure 2 to fasten the second base from the first direction.

[0009] Optionally, the number of the inclined side surfaces of the wedge block is two, so as to push the hook structure 2 to fasten the second base from the second direction and the third direction.

[0010] Thus, the hook structure can fasten the second base from the same direction, or fasten the second base from different directions for use in different scenarios.

[0011] Optionally, the hook structure 2 is provided with an inclined side surface, and the inclined side surface of the hook structure 2 matches the inclined side surface of the wedge block.

[0012] Thereby, it is ensured that the wedge block can better push the hook structure 2, and after the wedge block is installed in place, the volume of the device will not be increased extra.

[0013] Optionally, the hook structure 2 includes: a connection block 21 for detachably connecting to the connection portion 1; and a hook 22, disposed on the connection block 21, for connecting to the second base.

[0014] Optionally, the device further comprises: a support rod 4, which is arranged between the hook structure 2 and the bottom of the base connecting device and is used to support the second base.

[0015] Optionally, the device further comprises: a fixing structure 5 , which is arranged on the travel limiter 3 , and when the hook structure 2 fastens the second base, the fixing structure 5 is used to fix the travel limiter 3 .

[0016] Thereby, the travel limiter is prevented from falling off, and it is ensured that the hook structure can stably fasten the second base.

[0017] Optionally, the device further comprises: a fixing hole 6, arranged in the connecting part 1, for fixing the connecting part 1 on the first base.

[0018] Thereby, a firm connection between the connecting portion and the first base is ensured.

[0019] Optionally, the device further comprises: a guide block 7, and when the hook structure 2 is connected to the second base, the guide block 7 is used to guide the installation of the travel limiter 3, and the travel limiter 3 is limited between the guide block 7 and the second base.

[0020] Thus, the guide block guides the installation direction of the travel limiter to prevent the travel limiter from shaking left and right during the installation process and causing displacement.

[0021] Another aspect of the present invention provides an air conditioner, comprising the base connecting device as described above.

[0022] The advantages of the air conditioner and the base connection device described above relative to the prior art are the same and will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] 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.

[0033] Embodiment 1:

[0034] This embodiment provides a base connection device. Figure 1 This is a schematic diagram of the structure of a base connection device provided by an embodiment of the present invention. Figure 1 , while combining Figure 2-4B ,right Figure 1 The structure shown is described in detail.

[0035] In this embodiment, the first base and the second base are respectively the lower base and the upper base of the air conditioner as an example to illustrate the application scenario of the base connection device, and the left and right sides of the lower base and the upper base of the air conditioner should be connected by the base connection device in this embodiment. It can be understood that the base connection device can also be used in other structures with connection requirements.

[0036] like Figure 1 As shown, the base connection device includes a connection part 1, a hook structure 2 and a travel limiter 3, the connection part 1 is used to connect the first base, the hook structure 2 is detachably connected to the connection part 1, and is used to connect the second base, and the travel limiter 3 abuts against the hook structure 2 to prevent the hook structure 2 from escaping from the second base. The first base is, for example, the lower base of the air conditioner, and the second base is, for example, the upper base of the air conditioner.

[0037] In this embodiment, the travel limiter 3 is a wedge-shaped block with an inclined side surface, and the inclined side surface of the wedge-shaped block abuts against the hook structure 2 to push the hook structure 2 to move in the direction of fastening the second base. The wedge-shaped block is used to further push the hook structure 2 to move in the direction of fastening the second base. When the wedge-shaped block is installed in place (for example, the bottom surface of the wedge-shaped block contacts the hook structure 2), the connection between the hook structure 2 and the second base can be locked, making the connection between the hook structure 2 and the second base more secure.

[0038] Furthermore, the hook structure 2 is provided with an inclined side surface, and the inclined side surface of the hook structure 2 matches the inclined side surface of the wedge block.

[0039] In this embodiment, the hook structure 2 includes a connecting block 21 and a hook 22. The hook 22 is arranged on the connecting block 21, and the connecting block 21 is detachably connected to the connecting portion 1. The connecting block 21 is provided with an inclined side surface, and the inclined side surface of the connecting block 21 is the inclined side surface of the hook structure 2. The wedge block is used to push the inclined side surface of the connecting block 21 so that the hook 22 fastens the second base.

[0040] The number of the inclined side surfaces of the wedge block is one, so as to push the hook structure 2 to fasten the second base from the first direction. Figure 1 , one side of the wedge block is set as an inclined side, namely the fourth inclined side 31; one side of the connecting block 21 is also set as an inclined side, namely the first inclined side 211. Further, the first inclined side 211 and the fourth inclined side 31 can cooperate with each other, the first inclined side 211 is inclined in the direction of making the bottom of the connecting block 21 wider, and the fourth inclined side 31 is inclined in the direction of making the bottom edge of the wedge block narrower, so that when the wedge block is installed, under the action of the wedge block, the connecting block 21 and the hook 22 are pushed to move in the direction of fastening the second base, so as to fasten the second base from the first direction. The movement direction of the hook 22 is, for example, Figure 1 In the upward movement direction, the hook 22 moves upward and fastens the second base. Figure 1 The distance d shown is the distance that the hook structure 2 is pushed to move after the wedge block is installed. In this embodiment, the hook structure 2 is connected to the second base along one direction.

[0041] In the base connection device, the travel limiter 3 abuts against the hook structure 2, which can prevent the hook structure 2 from escaping in the direction of leaving the second base. There is no need to use spring parts, which reduces the assembly of springs and hook parts in the related technology, thereby shortening the assembly process and improving assembly efficiency. In addition, the travel limiter will not cause fatigue failure or entanglement due to long-term use, which effectively reduces costs and is more economical.

[0042] In this embodiment, the base connection device further includes a support rod 4, which is disposed between the hook structure 2 and the bottom of the base connection device and is used to support the second base. Figure 2 The support rod 4 is the main force-bearing member connecting the first base and the second base. Taking the first base as the lower base of the air conditioner and the second base as the upper base of the air conditioner as an example, the upper base and the lower base are placed in the upper and lower positions in the vertical direction, so the support rod 4 can support the upper base of the air conditioner.

[0043] In this embodiment, the base connecting device also includes a fixing structure 5, which is arranged on the travel limiter 3. When the hook structure 2 fastens the second base, the fixing structure 5 is used to fix the travel limiter 3, thereby preventing the travel limiter from falling off and ensuring that the hook structure 2 can stably fasten the second base.

[0044] Specifically, see Figure 3 The fixing structure 5 is, for example, a fastening structure. When the wedge block is installed in place, the fastening structure, for example, fastens the support rod 4 to prevent the wedge block from falling off when it is under pressure (for example, pressure from the second base and the hook structure 2), thereby ensuring that the hook structure 2 stably fastens the second base.

[0045] In this embodiment, the base connection device further includes a fixing hole 6, which is disposed in the connecting portion 1 and is used to fix the connecting portion 1 on the first base, thereby ensuring a firm connection between the connecting portion 1 and the first base.

[0046] In this embodiment, the base connection device further includes a guide block 7. When the hook structure 2 is connected to the second base, the guide block 7 is used to install and guide the travel limiter 3, so that the travel limiter 3 is limited between the guide block 7 and the second base. The guide block 7 is, for example, arranged on the connection portion 1 inside the support rod 4. The distance between the guide block 7 and the support rod 4 is equal to or slightly less than the thickness of the wedge block. When the hook structure 2 is connected to the second base, the wedge block is installed at the support rod 4, the wedge block squeezes the guide block 7, and the wedge block is limited between the guide block 7 and the second base. The guide block 7 can guide the wedge block to prevent the wedge block from shaking left and right.

[0047] In this embodiment, a handle may also be provided on the connecting portion 1 to facilitate operators to use the base connecting device to connect the base.

[0048] Taking the first base as the lower base of the air conditioner and the second base as the upper base of the air conditioner as an example, the process of connecting the bases by the base connection device is explained. In this embodiment, the connection body 8 for connecting the bases includes a connection part 1, a hook structure 2, a support rod 4, a fixing hole 6, and a guide block 7. First, the hook structure 2 is inserted into the connection part 1, and the connection part 1 is fixed on the lower base. The hook 22 on the hook structure 2 is inserted into the groove of the upper base 9, so that the connection body 8 connects the lower base and the upper base respectively. At this time, the wedge block has not been installed. Since the hook structure 2 is not pressed by the wedge block, the hook 22 only enters the groove of the upper base 9 and is not fastened. Figure 4A Then, the wedge block is installed, and the guide block 7 guides the installation direction of the wedge block to prevent the wedge block from being offset. Under the push of the wedge block, the hook structure 2 moves in the direction of fastening the upper base 9, so that the hook 22 moves in the fastening direction after entering the groove of the upper base 9. When the wedge block is installed to the bottom, the hook 22 fastens the upper base 9, as shown in FIG. Figure 4B As shown, finally, the fixing structure 5 is fastened to the support rod 4 to fix the wedge block.

[0049] In this embodiment, the connecting part and the hook structure are detachably connected. The first base is connected by the connecting part, the second base is connected by the hook structure, and the stroke limiter is abutted against the hook structure to prevent the hook structure from falling out, making the base connection more secure, and the stroke limiter will not cause fatigue failure or entanglement due to long-term use, thereby effectively reducing costs.

[0050] Embodiment 2:

[0051] This embodiment provides a base connection device. Compared with the base connection device described in the first embodiment, the hook structure 2 in the base connection device in this embodiment can be connected to the second base from two directions. Accordingly, the number of the inclined side surfaces of the wedge block is two, and the two inclined side surfaces push the hook structure 2 to buckle the second base from the second direction and the third direction respectively.

[0052] Different from the first embodiment, in this embodiment, the two side surfaces of the connecting block 21 are configured as oblique side surfaces, and the two side surfaces of the wedge block are also configured as oblique side surfaces.

[0053] See also Figure 5A and 5B, the two side surfaces of the wedge block are set as oblique side surfaces, namely the fifth oblique side surface 32 and the sixth oblique side surface 33; the two side surfaces of the connecting block 21 are also set as oblique side surfaces, namely the second oblique side surface 212 and the third oblique side surface 213. Furthermore, the second oblique side surface 212 and the fifth oblique side surface 32 can cooperate with each other, and the third oblique side surface 213 and the sixth oblique side surface 33 can cooperate with each other. The second oblique side surface 212 and the third oblique side surface 213 are inclined in the direction of making the bottom of the connecting block 21 wider, and the fifth oblique side surface 32 and the sixth oblique side surface 33 are inclined in the direction of making the bottom edge of the wedge block narrower, so that when the wedge block is installed, under the push of the fifth oblique side surface 32 and the sixth oblique side surface 33, the two hooks of the hook structure 2 are pushed to move in two different directions respectively, so as to fasten the second base from the second direction and the third direction. In this embodiment, the movement directions of the two hooks in the hook structure are, for example, Figure 5A In the leftward movement direction and the rightward movement direction, one hook moves to the left to fasten the second base, and one hook moves to the right to fasten the second base. For details not covered in this embodiment, please refer to the description in the first embodiment, which will not be repeated here.

[0054] In this embodiment, a hook structure is provided to connect the second base from two directions, and two inclined side surfaces are provided for the wedge block, so that the wedge block pushes the hook structure to fasten the second base from two directions, thereby making the base connection device have a more secure connection effect.

The air conditioner and the base connection device have the same advantages over the prior art. For details not covered in this embodiment, please refer to the above-mentioned Embodiment 1 and Embodiment 2, which will not be repeated here.

[0057] To summarize, in the base connection device and the air conditioner provided by the embodiments of the present invention, the connection part and the hook structure are configured as a detachable connection structure, the first base is connected by the connection part, the second base is connected by the hook structure, and the travel limiter abuts against the hook structure to prevent the hook structure from coming out, so that the base connection is more secure and the second base can be fastened from one direction or two directions, thereby improving the connection performance. The wedge block will not fail due to fatigue or entanglement due to long-term use, thereby effectively reducing the cost.
