[0002] With the improvement of people's living standards, air conditioners have become indispensable electrical appliances in people's lives. Among them, the water pump is one of the important components of the air conditioner. In related technologies, the water pump is installed inside the air conditioner via a water pump bracket, and the water pump and the water pump bracket are connected by threads. During production, the water pump and water pump bracket are installed on an assembly line, and the water pump is fixed to the water pump bracket using screws. However, because the water pump bracket is placed directly on the equipment on the assembly line, when the screw is screwed into the threaded hole of the water pump bracket, in order to avoid the screw penetrating through the bottom surface of the water pump bracket and scratching the equipment on the assembly line, the screw cannot be fully tightened, resulting in reduced stability of the water pump and water pump bracket installation. Therefore, how to install the water pump and water pump bracket in a way that ensures the screw is properly installed without damaging the equipment on the assembly line has become an urgent problem to be solved.

[0042] In the description of this embodiment, the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0043] like Figure 1 and Figure 2 As shown, the water pump 20 assembly of the air conditioner in this embodiment includes a water pump 20 and a bracket 30. The water pump 20 is mounted in the air conditioner via the bracket 30. The water pump 20 has multiple through holes 21, and the bracket 30 has multiple threaded holes 31, so that the water pump 20 and the bracket 30 are connected by screw threads.

[0044] Before the water pump 20 assembly is installed in the air conditioner, the water pump 20 and the bracket 30 need to be connected together by screw threads. In other words, the water pump 20 and the bracket 30 are pre-installed before being installed in the air conditioner.

[0045] The pre-assembly fixture 10 of an embodiment of the present invention is described below with reference to the accompanying drawings.

[0046] like Figures 1-7 As shown, the pre-assembly fixture 10 of this utility model embodiment includes a support platform 100 and a positioning column 200.

[0047] The support platform 100 is used to place the water pump 20 bracket 30. The support platform 100 is provided with multiple receiving slots 110, and the multiple receiving slots 110 are provided one-to-one with the multiple threaded holes 31 of the water pump 20 bracket 30. That is to say, when the bracket 30 is placed on the support platform 100, the multiple threaded holes 31 on the bracket 30 can correspond one-to-one with the multiple receiving slots 110.

[0048] Multiple positioning posts 200 are arranged one-to-one in multiple receiving slots 110. Each positioning post 200 can rise and fall within its corresponding receiving slot 110, either extending out of or retracting into it. The positioning posts 200 are configured to conform to the threaded holes 31. That is, when the positioning post 200 extends out of the receiving slot 110, it can sequentially pass through the threaded hole 31 of the bracket 30 and the corresponding through hole 21 of the water pump 20, thereby positioning the bracket 30 and the water pump 20 with the multiple positioning posts 200, so that screws can be installed into the through hole 21 of the water pump 20 and the corresponding threaded hole 31 of the bracket 30.

[0049] The specific implementation of the pre-assembly fixture 10 of this utility model is described below with reference to the accompanying drawings.

[0050] The pre-installed fixture 10 of this embodiment is placed on the equipment of the production line. The upper end of each positioning post 200 extends out of the corresponding receiving groove 110, so that each positioning post 200 can pass through the through hole 21 of the water pump 20 and the threaded hole 31 of the corresponding bracket 30 to position the bracket 30 and the water pump 20 placed on the bracket 30.

[0051] When installing a screw in the through hole 21 and the corresponding threaded hole 31, the screw passes through the through hole 21 and the threaded hole 31 in sequence. The screw presses against the positioning post 200, causing the positioning post 200 to descend so that the screw can continue to be screwed downwards until the screw is installed in place. When the lower end of the screw exits the threaded hole 31, the positioning post 200 can continue to descend so that the screw can continue to be screwed downwards into the receiving groove 110, ensuring that the screw is installed in place.

[0052] Compared with related technologies, the pre-assembly fixture 10 of this embodiment includes a support platform 100 with multiple receiving slots 110, each receiving slot 110 containing a liftable positioning post 200. The multiple positioning posts 200 position the through hole 21 of the water pump 20 and the threaded hole 31 of the bracket 30. When installing screws, the screws press against the positioning posts 200, causing the positioning posts 200 to drop under pressure, thus avoiding the screws and ensuring proper screw installation. Furthermore, when installing screws, the water pump 20 and bracket 30 are mounted on the pre-assembly fixture 10 of this embodiment, ensuring that the screws do not come into contact with the equipment on the production line, thus preventing damage to the equipment.

[0053] For example Figure 5 As shown, the support platform 100 is provided with three receiving slots 110 and three positioning posts 200, which are arranged one-to-one in the three receiving slots 110.

[0054] In some embodiments, such as Figure 3As shown, each positioning post 200 is a cylinder, and the radial dimension of each positioning post 200 is adapted to the radial dimension of the threaded hole 31 of the bracket 30. Since the radial dimensions of the through hole 21 of different specifications of water pumps 20 and the threaded hole 31 of the bracket 30 are also different, the radial dimension of the positioning post 200 is not limited here.

[0055] In some embodiments, such as Figure 3 As shown, the pre-assembly fixture 10 of this embodiment further includes an elastic element 300, which is connected between the receiving groove 110 and the positioning post 200. The elastic element 300 is configured to provide a lifting force to the positioning post 200, causing the positioning post 200 to extend out of the receiving groove 110. That is, the elastic element 300 applies a continuous upward elastic force to the positioning post 200 so that the positioning post 200 extends out of the receiving groove 110 when it is not subjected to pressure from the screw. When the positioning post 200 is subjected to pressure from the screw, the elastic element 300 retracts downward to allow the screw to screw downward. The structure is simple and easy to manufacture.

[0056] Optionally, the elastic element 300 is a spring. For example... Figure 3 As shown, the upper end of the spring abuts against the lower end of the positioning post 200, and the lower end of the spring abuts against the bottom wall of the receiving groove 110.

[0057] In some embodiments, such as Figure 3 As shown, the lower end 210 of the positioning post 200 is provided with a downward-opening mounting groove 211, the extension direction of which is consistent with the vertical direction. The upper end of the elastic member 300 is installed in the mounting groove 211, and the other end contacts and abuts against the bottom wall of the mounting groove 211. Thus, when the elastic member 300 is compressed and contracts or expands, it can be guided by the mounting groove 211, making the force on the positioning post 200 more even and ensuring that the positioning post 200 can rise and fall smoothly.

[0058] In some embodiments, such as Figure 4As shown, the receiving groove 110 includes a first segment 111 and a second segment 112 connected in sequence; the first segment 111 is located above the second segment 112, and the radial dimension of the second segment 112 is larger than the radial dimension of the first segment 111. The first segment 111 and the second segment 112 are connected by a first annular stop surface. The positioning post 200 includes a third segment 220 and a fourth segment 230 connected in sequence; the third segment 220 is located above the fourth segment 230, and the radial dimension of the fourth segment 230 is larger than the radial dimension of the third segment 220 and the radial dimension of the first segment 111. The third segment 220 and the fourth segment 230 are connected by a second annular stop surface, and the fourth segment 230 is disposed in the second segment 112. The positioning post 200 is configured such that when the first annular stop surface contacts the second annular stop surface, the third segment 220 extends out of the receiving groove 110. Thus, the first annular stop surface and the second annular stop surface restrict the positioning post 200 from continuing to move upward, preventing the positioning post 200 from dislodging from the receiving groove 110.

[0059] In some embodiments, the first segment 111 has a vertical dimension of 5mm to 10mm. Optionally, the vertical dimension of the first segment 111 includes, but is not limited to, 5mm, 6mm, 7mm, 8mm, 9mm, or 10mm. The third segment 220 has a vertical dimension of 10mm to 15mm. Optionally, the vertical dimension of the third segment 220 includes, but is not limited to, 10mm, 11mm, 12mm, 13mm, 14mm, or 15mm. That is, the dimension of the third segment 220 is larger than the dimension of the first segment 111, ensuring that the third segment 220 can extend from the receiving groove 110, and avoiding the third segment 220 being too large, reducing structural redundancy and lowering manufacturing costs.

[0060] In some embodiments, such as Figure 4 As shown, the support platform 100 includes a first part 120 and a second part 130.

[0061] The upper surface of the first part 120 is provided with a plurality of first holes, forming a first segment 111, wherein the first holes are through holes. The second part 130 is mounted on the upper surface of the first part 120, and the lower surface of the second part 130 is provided with a plurality of second holes, forming a second segment 112. The plurality of second holes correspond one-to-one with the plurality of first holes, and the radial dimension of the second hole is larger than the radial dimension of the first hole. The first hole and its corresponding second hole form a receiving groove 110.

[0062] When installing the pre-assembly fixture 10 of this embodiment, the multiple positioning posts 200 and multiple elastic elements 300 are first installed one-to-one in the multiple second holes, and then the first part 120 is installed on the second part 130. This makes the assembly of the pre-assembly fixture 10 of this embodiment convenient.

[0063] Furthermore, the first part 120 and the second part 130 are threadedly connected. Specifically, the first part 120 is provided with multiple through holes, and the second part 130 is provided with multiple threaded mounting holes, so that the first part 120 and the second part 130 can be installed and fixed by threaded fasteners (e.g., screws).

[0064] In some other embodiments, the first portion 120 and the second portion 130 may be adhesively connected.

[0065] In some embodiments, a receiving space is defined between the positioning post 200 and the receiving groove 110. An air bladder (not shown) filled with gas is disposed within the receiving space, configured to provide a lifting force to the positioning post 200, causing it to extend out of the receiving groove 110. The gas in the air bladder is compressible and expandable. That is, the air bladder applies a continuous upward elastic force to the positioning post 200, allowing the positioning post 200 to extend out of the receiving groove 110 when not under pressure from the screw. When the positioning post 200 is under pressure from the screw, the gas in the air bladder contracts under pressure, allowing the screw to be screwed downwards. This design is simple and easy to manufacture.

[0066] Alternatively, the gas inside the airbag can be nitrogen.

[0067] In some embodiments, such as Figure 7 As shown, the support platform 100 is also provided with a first positioning member 410 and a second positioning member 420. The first positioning member 410 has a first limiting surface 411, and the second positioning member 420 has a second limiting surface 421, forming an included angle between the first limiting surface 411 and the second limiting surface 421. The first positioning member 410 and the second positioning member 420 are configured such that when both the first limiting surface 411 and the second limiting surface 421 are in contact with the water pump 20 bracket 30, the plurality of receiving grooves 110 correspond one-to-one with the plurality of threaded holes 31 of the water pump 20 bracket 30. Thus, the bracket 30 is positioned by the first positioning member 410 and the second positioning member 420, so that the plurality of positioning posts 200 can cooperate with the plurality of threaded holes 31 and through holes 21.

[0068] Furthermore, such as Figure 7 As shown, the first positioning member 410 is flat, and a first limiting surface 411 is formed on one side of the first positioning member 410 in the width direction. The second positioning member 420 is flat, and a second limiting surface 421 is formed on one side of the second positioning member 420 in the width direction. This not only simplifies the structure but also gives the first positioning member 410 and the second positioning member 420 sufficient structural strength.

[0069] Optionally, the first positioning member 410 is an upwardly extending first flange, and the second positioning member 420 is an upwardly extending second flange. This allows the first positioning member 410 and the second positioning member 420 to be integrally formed with the first part 120, eliminating the need for further installation of the first positioning member 410 and the second positioning member 420, thus saving the assembly process of the pre-installation fixture 10 in this embodiment.
