Description

Technical Field

[0001] This utility model relates to the technical field of heat pumps and air conditioning accessories, and in particular to a fixing buckle and a heat pump. Background Technology

[0002] In the heat pump and air conditioning industry, electric heating wires are typically installed on the outdoor unit chassis to prevent icing. The electric heating wires are usually fixed to the outdoor unit chassis using a combination of screws and pressure plates. This method has the following drawbacks:

[0003] 1. When operators fix the device on-site, the screws can easily scratch the electric heating wires.

[0004] 2. The tightening force of the screws is difficult to control. If it is too tight, the heating wire is not easy to adjust and a large pulling force is required to adjust its position. If it becomes loose during the pulling process, the screws need to be tightened again. At the same time, the large pulling force will also cause the pressure plate to wear the heating wire. If the screw is too loose after tightening, the heating wire will bend in an undulating shape, with an uneven surface, and will not be able to fully fit close to the chassis that needs to be heated, thus reducing the heating effect of the heating wire.

[0005] 3. When using pressure plates to fix the electric heating wires, operators can place them freely based on experience, which cannot effectively fix them.

[0006] 4. When users replace the electric heating wire themselves, they need to loosen the screws to remove the electric heating wire. The electric heating wire is often located close to the fins, which can easily cause injury during disassembly and is inconvenient to install and remove.

[0007] Therefore, there is an urgent need to provide a new type of fixing clip and heat pump to solve the above-mentioned technical problems in the prior art. Utility Model Content

[0008] The purpose of this utility model is to provide a fixing buckle that facilitates the fixing and disassembly of the electric heating wire, and improves the fit between the electric heating wire and the outdoor unit, thereby enhancing the heating effect of the electric heating.

[0009] To achieve this objective, the present invention adopts the following technical solution:

[0010] The fixing buckle includes a fixing base and a fixing plate. The fixing base is configured to be fixed to an external device. One end of the fixing plate is provided with a snap-fit ​​protrusion, which snaps and fixes to one end of the fixing base. The other end of the fixing plate is provided with a rotating ring, and the other end of the fixing base is provided with a fixing ring. The fixing ring has an installation opening, and the rotating ring can be inserted into the fixing ring through the installation opening, so that the fixing plate and the fixing base are rotatably connected. When the fixing plate and the fixing base are fastened together, there are several receiving spaces between the fixing plate and the fixing base for accommodating electric heating wires.

[0011] Optionally, the fixed base extends along a first direction, and one end of the fixed base along the first direction is provided with a snap-fit ​​portion extending along a second direction. The snap-fit ​​portion has a snap-fit ​​hole, and the snap-fit ​​protrusion snaps into the snap-fit ​​hole. The first direction is perpendicular to the second direction.

[0012] Optionally, the fixing plate is provided with two receiving grooves at each end along the first direction, and the receiving grooves and the fixing base form the receiving space.

[0013] Optionally, the receiving groove near the snap-fit ​​portion of the two receiving grooves is square, and the fixing plate is provided with a snap-fit ​​portion extending in the second direction at one end near the snap-fit ​​portion along the first direction. The receiving groove near the snap-fit ​​portion is at least partially formed by the snap-fit ​​portion, and the snap-fit ​​portion is provided with the snap-fit ​​protrusion.

[0014] Optionally, the inner top wall of the receiving groove near the above-mentioned snap-fit ​​portion is provided with a fixing boss that protrudes toward the fixing base along the second direction, and the end of the fixing boss can abut against the electric heating wire.

[0015] Optionally, the receiving groove farther from the snap-fit ​​portion of the two receiving grooves is fan-shaped, and the diameter of the receiving groove farther from the snap-fit ​​portion is not less than the diameter of the electric heating wire.

[0016] Optionally, the fixing plate includes a connecting portion extending along the first direction, with two receiving grooves connected to each end of the connecting portion, and the gap between the connecting portion and the fixing base along the second direction is not greater than the minimum value of the gap between the receiving groove and the fixing base along the second direction.

[0017] Optionally, the connection between the snap-fit ​​portion and the fixed base is elastically connected, and the snap-fit ​​portion, the fixed base, and the fixed ring are integrally formed.

[0018] Optionally, the bottom wall of the aforementioned fixed base is provided with a welding area, which is then spot-welded to an external device.

[0019] Another objective of this utility model is to provide a heat pump, which includes an outdoor unit body, an electric heating wire, and a fixing buckle as described in any of the above embodiments. The fixing base is fixed to the outer wall of the outdoor unit body, and the electric heating wire passes through the accommodating space.

[0020] Beneficial effects:

[0021] The fixing buckle of this utility model consists of a fixing base and a fixing plate, which are detachably connected. First, the fixing base is used to secure the device to the external unit. Then, the rotating ring of the fixing plate extends into the fixing ring through the mounting opening. The rotation of the rotating ring within the fixing ring engages the fixing base and the fixing plate. Once engaged, the snap-fit ​​protrusion of the fixing plate engages with the fixing base, thus securing the fixing base and the fixing plate. At this point, several receiving spaces are formed between the fixing plate and the fixing base, thereby accommodating and securing the electric heating wire. This fixing buckle facilitates the fixing and disassembly of the electric heating wire, and improves the fit between the electric heating wire and the external unit, enhancing the heating effect.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0032] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0033] The first direction described in this embodiment is: Figure 1 The X direction shown is the horizontal direction; the second direction is... Figure 1 The Y direction shown is the vertical direction, while the X direction is perpendicular to the Y direction.

[0034] like Figure 1As shown, the fixing buckle includes a fixing base 100 and a fixing buckle plate 200. The fixing base 100 is configured to be fixed to an external device. One end of the fixing buckle plate 200 is provided with a snap-fit ​​protrusion 210, which snaps and fixes to one end of the fixing base 100. The other end of the fixing buckle plate 200 is provided with a rotating ring 220, and the other end of the fixing base 100 is provided with a fixing ring 120. The fixing ring 120 has an installation opening 121, and the rotating ring 220 can be inserted into the fixing ring 120 through the installation opening 121, so that the fixing buckle plate 200 and the fixing base 100 are rotatably connected. When the fixing buckle plate 200 and the fixing base 100 are fastened together, there are several receiving spaces between the fixing buckle plate 200 and the fixing base 100 for accommodating the electric heating wire 10.

[0035] The fixing buckle in this embodiment specifically consists of a fixing base 100 and a fixing plate 200, which are detachably connected. First, the fixing base 100 is fixed to the external device. Then, the rotating ring 220 of the fixing plate 200 extends into the fixing ring 120 from the mounting port 121. By rotating the rotating ring 220 inside the fixing ring 120, the fixing base 100 and the fixing plate 200 of the fixing buckle are engaged. When the engagement is complete, the snap-fit ​​protrusion 210 of the fixing plate 200 engages and fixes with the fixing base 100, thus fixing the fixing base 100 and the fixing plate 200. At this time, several receiving spaces are formed between the fixing plate 200 and the fixing base 100, thereby accommodating and fixing the electric heating wire 10. This fixing buckle facilitates the fixing and disassembly of the electric heating wire 10, and the electric heating wire 10 has better fit with the outdoor unit, improving the heating effect of the electric heating.

[0036] like Figure 1 and Figure 2 As shown, when the fixed base 100 and the fixed buckle 200 are assembled, they can also be... Figure 2 As shown by the arrow, the fixing plate 200 is slid into the fixing base 100 from the side along the horizontal direction, which makes the installation and assembly of the fixing buckle more convenient. This will not be described in detail here.

[0037] Furthermore, such as Figure 1 and Figure 3 As shown, the aforementioned fixing base 100 extends along a first direction, and one end of the fixing base 100 along the first direction is provided with a snap-fit ​​portion 111 extending along a second direction. The snap-fit ​​portion 111 has a snap-fit ​​hole 110, and the snap-fit ​​protrusion 210 snaps into the snap-fit ​​hole 110. The first direction is perpendicular to the second direction. By using the snap-fit ​​engagement of the snap-fit ​​hole 110 and the snap-fit ​​protrusion 210, reliable snap-fit ​​fixing can be achieved, and it is easy to release the snap-fit, so as to disassemble and replace the electric heating wire 10.

[0038] In this embodiment, the fixing plate 200 is provided with two corresponding receiving slots 230 at both ends along the first direction, and the receiving slots 230 and the fixing base 100 form the receiving space. The two receiving slots 230 can fix two electric heating wires 10, or facilitate the bending of one electric heating wire 10 and fixing it with a fixing buckle, reducing the use of fixing buckles and lowering the installation cost.

[0039] Specifically, of the two aforementioned receiving grooves 230, the receiving groove 230 near the aforementioned snap-fit ​​portion 111 is square. The fixing plate 200 has a snap-fit ​​portion 211 extending in the second direction at one end near the aforementioned snap-fit ​​portion 111 along the first direction. The snap-fit ​​portion 211 forms at least a portion of the aforementioned receiving groove 230 near the aforementioned snap-fit ​​portion 111, and the snap-fit ​​portion 211 is provided with the aforementioned snap-fit ​​protrusion 210. Thus, the snap-fit ​​portion 211 extending in the second direction can not only form the aforementioned square receiving groove 230, but also cooperate with the aforementioned snap-fit ​​portion 111 to achieve snap-fit ​​fixation between the snap-fit ​​protrusion 210 and the aforementioned snap-fit ​​hole 110, which will not be elaborated further here.

[0040] Please continue to refer to this. Figure 1 and Figure 3 The inner top wall of the receiving groove 230 near the aforementioned snap-fit ​​portion 111 is provided with a fixing boss 231 that protrudes towards the fixing base 100 along the aforementioned second direction. The end of the fixing boss 231 can abut against the electric heating wire 10. The fixing boss 231 can press down and fix the electric heating wire 10, improving the fixing effect of the square receiving groove 230 on the electric heating wire 10, preventing the round electric heating wire 10 from shifting and sliding within the square receiving groove 230, and improving the reliability and stability of the fixation.

[0041] Furthermore, in this embodiment, the receiving groove 230 farther from the latching portion 111 of the two aforementioned receiving grooves 230 is fan-shaped, and the diameter of the receiving groove 230 farther from the latching portion 111 is not less than the diameter of the electric heating wire 10. Therefore, the fan-shaped receiving groove 230 can be used to receive and fix the circular electric heating wire 10, and the contact area between the fan-shaped receiving groove 230 and the electric heating wire 10 is larger, resulting in a better fixing effect.

[0042] like Figure 3As shown, the aforementioned fixing plate 200 includes a connecting portion 240 extending along the first direction. Two receiving grooves 230 are respectively connected to both ends of the connecting portion 240. The gap between the connecting portion 240 and the fixing base 100 along the second direction is no greater than the minimum value of the gap between the receiving grooves 230 and the fixing base 100 along the second direction. The connecting portion 240 not only connects the two receiving grooves 230 but also fits as close as possible to the top wall of the fixing base 100, ensuring the stability of the connection between the fixing buckle and the fixing base 100.

[0043] In this embodiment, the snap-fit ​​part 111 and the fixed base 100 are elastically connected, and the snap-fit ​​part 111, the fixed base 100, and the fixing ring 120 are integrally formed. During use, an external tool, such as a screwdriver, can be used to pry the snap-fit ​​part 111 outwards, making the snap-fit ​​part 111 form an obtuse angle with the fixed base 100. Then, the fixing plate 200 is pressed down. After installation, the snap-fit ​​part 111 is released, and it retracts under the action of elastic force, causing the snap-fit ​​hole 110 on the snap-fit ​​part 111 to engage and fix with the snap-fit ​​protrusion 210 on the fixing plate 200, improving installation efficiency and making installation and disassembly more convenient. In this embodiment, the snap-fit ​​part 111, the fixed base 100, and the fixing ring 120 are integrally formed, allowing for sheet metal forming from a single piece of metal or plastic injection molding, reducing manufacturing costs.

[0044] Similarly, the fixing plate 200 is also integrally formed with the aforementioned receiving groove 230, rotating ring 220, and snap-fit ​​protrusion 210, which are formed by sheet metal forming or plastic injection molding, and will not be described in detail here.

[0045] Optionally, the bottom wall of the aforementioned fixed base 100 is provided with a welding area 130, which is then spot-welded to the external equipment. Using welding, specifically spot welding, to fix the fixed base 100 to the external equipment (here, the outdoor unit of a heat pump or air conditioner) can improve the fixing effect between the fixed base 100 and the external equipment and enhance the stability of the installation.

[0046] This embodiment also provides a heat pump, which includes an outdoor unit body, an electric heating wire 10, and a fixing clip as described in any of the above embodiments. The fixing base 100 is fixed to the outer wall of the outdoor unit body, and the electric heating wire 10 passes through the receiving space. The heat pump uses the fixing clip to fix the electric heating wire 10 to the outer wall of the outdoor unit body, thus achieving the beneficial effects of the fixing clip described in any of the above embodiments. Specifically, after using the fixing clip, the heat pump can easily fix the electric heating wire 10, improving installation efficiency. Furthermore, the electric heating wire 10 has better adhesion to the outdoor unit body, improving heating efficiency, preventing frost buildup on the outdoor unit body, and improving defrosting efficiency.

[0047] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
