Description

Technical Field

[0001] This utility model relates to the technical field of fixing devices, and more specifically, to a pipe fixing device and a heat pump water machine. Background Technology

[0002] In the existing technology, when it is necessary to fix the pipe fitting to the target carrier, structures such as clamps are usually used. Specifically, the clamp is used to hold the pipe fitting, and then one operator assists in supporting the pipe fitting while another operator fixes the clamp to the target carrier; or, the operator supports the already assembled pipe fitting and clamp with one hand and fixes the clamp to the target carrier with the other hand. Regardless of the method, it is very inconvenient and inefficient. Utility Model Content

[0003] The first objective of this utility model is to provide a pipe fitting fixing device to solve the technical problems of inconvenience and low efficiency when fixing pipe fittings using existing pipe fitting fixing devices.

[0004] The pipe fitting fixing device provided by this utility model includes a pipe fitting connector, which includes a gripping part and a hook part. The gripping part includes a clamping part for clamping the pipe fitting. Perpendicular to the axial direction of the pipe fitting, at least one side of the clamping part is provided with a fixing ear. The hook part is provided above the fixing ear. The hook part can be hung on a hanging structure, and the fixing ear can be fixed to the hanging structure.

[0005] The pipe fixing device provided by this utility model can produce the following beneficial effects:

[0006] The pipe fixing device provided by this utility model can fix the pipes that need to be fixed to the hanging structure. Specifically, when fixing the pipes, the pipes can be clamped by the clamping part of the pipe connector first, then the pipes can be hung on the hanging structure by the hook part of the pipe connector, and finally the fixing ear of the pipe connector can be fixed to the hanging structure.

[0007] It is evident that the pipe fitting fixing device can effectively secure the pipe fitting. Furthermore, by setting up hooks and attaching them to the hanging structure, operators can independently complete the fixing operation of the fixing ears without the assistance of others or the need to support the pipe fitting or pipe fitting connector with one hand, but only use the other hand to fix the fixing ears. In other words, the pipe fitting connector also serves as an auxiliary tooling, making the fixing of pipe fittings very convenient, quick, and efficient.

[0008] In addition, by defining the connection position between the pipe fitting and the clamping part, the pipe fitting connector can also play a positioning role for the pipe fitting.

[0009] Furthermore, perpendicular to the axial direction of the pipe fitting, the clamping portion has fixing ears on both sides; the hook portion includes two hooks, each positioned above one of the fixing ears. With this technical solution, firstly, the two hooks have a stronger load-bearing capacity, and since they are positioned on both sides of the clamping portion, the force applied to the pipe fitting by the pipe fitting fixing component is more balanced, making it less prone to skewing of the pipe fitting and the pipe fitting fixing component, resulting in higher positional accuracy and better positional stability.

[0010] Furthermore, the hook includes an integrally formed bent portion and an extension portion. The bent portion is integrally formed or fixedly connected to the fixing ear. The extension portion is located at the end of the bent portion away from the fixing ear and extends downwards in a direction gradually away from the fixing ear. In this technical solution, the extension portion of the hook is obliquely positioned outwards relative to the fixing ear, and the opening is relatively large, making it easier to hang the hook on the hanging structure.

[0011] Furthermore, the angle between the extension and the fixing ear ranges from 8° to 10°. With this technical solution, the angle between the extension and the fixing ear satisfies the need for convenient hanging without being too large, which would cause the hook to detach from the hanging structure.

[0012] Furthermore, of the two fixing ears, one is provided with a circular through hole, and the other is provided with an oblong through hole, with the length direction of the oblong through hole perpendicular to the axial direction of the pipe fitting; the fastener can pass through the circular through hole and the oblong through hole to fix the fixing ear to the hanging structure. Under this technical solution, even if the gripping part has deformation or manufacturing error in the direction perpendicular to the axial direction of the pipe fitting, the oblong through hole can still ensure that the pipe fitting fixing part is fixed to the hanging structure.

[0013] Furthermore, the pipe fixing device also includes a carrier connector, which forms the hanging structure for fixed connection with the target carrier. The carrier connector is provided with a hanging groove, the hook portion can be hung on the groove wall, and the fixing ear can be fixedly connected to the groove wall. Under this technical solution, when fixing the pipe, the carrier connector is fixed to the target carrier, the pipe is fixedly connected to the pipe connector, and finally the pipe connector is fixed to the carrier connector. That is, the pipe connector fixes the pipe to the target carrier through the carrier connector. By setting a carrier connector and providing structures on the carrier connector that cooperate with the hook and fixing ear of the pipe connector, the structural changes to the target carrier can be greatly reduced.

[0014] Furthermore, the carrier connector includes a mounting plate and at least two spaced and oppositely arranged support plates. The mounting plate and the support plates together enclose the hanging groove. The hook portion can be hung on the mounting plate, and the side of the support plate away from the mounting plate can be fixed to the target carrier. In this technical solution, when fixing the pipe connector to the carrier connector, the hook is first hung on the mounting plate, and then the fixing lug is fixed to the mounting plate.

[0015] Furthermore, a support plate is provided on the left, right, and lower sides of the mounting plate, and each of the three support plates has a fixing flange on the side away from the mounting plate for fixed connection with the target carrier. In this technical solution, the three support plates jointly support the mounting plate, providing more stable support; the fixing flanges facilitate fixing the carrier connector to the target carrier.

[0016] Furthermore, the included angle between the support plate and the mounting plate is greater than or equal to 90°. Preferably, the included angle between the support plate and the mounting plate is greater than 90°. With this configuration, the support plate provides support not only in the direction perpendicular to the mounting plate but also in the direction parallel to the mounting plate, making the entire carrier connector more stable. In addition, the inclined arrangement of the support plate expands the operating space when fixing the flange, facilitating operation.

[0017] The second objective of this utility model is to provide a heat pump water machine to solve the technical problems of inconvenient operation and low efficiency when using the pipe fixing device in the prior art to fix the pipes.

[0018] The heat pump water heater provided by this utility model includes a housing and a water tank disposed inside the housing. The water pipe connected to the water tank is fixed to the inner wall of the housing by the aforementioned pipe fixing device.

[0019] The heat pump water machine provided by this utility model uses the above-mentioned pipe fixing device to fix the water pipe, so it is convenient to operate and highly efficient. Attached Figure Description

[0031] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0032] This embodiment provides a pipe fitting fixing device, such as Figure 5 and Figure 6 As shown, the pipe fitting fixing device includes a pipe fitting connector 100, which includes a gripping part 110 and a hook part. The gripping part 110 includes a clamping part 111 for clamping the pipe fitting. Perpendicular to the axial direction of the pipe fitting, at least one side of the clamping part 111 is provided with a fixing ear 112. The hook part is provided above the fixing ear 112. The hook part can be hung on the hanging structure, and the fixing ear 112 can be fixed to the hanging structure.

[0033] The pipe fixing device provided in this embodiment can fix the pipe to be fixed to the hanging structure. Specifically, when fixing the pipe, the pipe can be clamped by the clamping part 111 of the clamping part 110 of the pipe connector 100, and then the pipe can be hung on the hanging structure by the hook part of the pipe connector 100. Finally, the fixing ear 112 of the pipe connector 100 can be fixed to the hanging structure.

[0034] It is evident that the pipe fitting fixing device can fix the pipe fitting. Moreover, by setting up a hook and hanging the hook on the hanging structure, the operator can complete the fixing operation of the fixing ear 112 independently without the assistance of others, and without holding the pipe fitting or pipe fitting connector 100 with one hand, but only fixing the fixing ear 112 with the other hand. That is, the pipe fitting connector 100 also serves as an auxiliary tooling, making the fixing of the pipe fitting very convenient, quick and efficient.

[0035] Furthermore, by defining the connection position between the pipe fitting and the clamping part 111, the pipe fitting connector 100 can also position the pipe fitting.

[0036] Preferably, in addition to clamping the pipe fitting with the clamping part 111, the clamping part 111 can also be welded to the pipe fitting. Moreover, the welding position of the pipe fitting can be predetermined, thereby achieving precise assembly of the pipe fitting and the pipe fitting connector 100. After the pipe fitting connector 100 is fixed to the hanging structure, the pipe fitting can be accurately positioned and reliably fixed.

[0037] In this embodiment, the gripping part 110 and the hook part of the pipe connector 100 are integrally formed. Of course, in other embodiments of this application, the gripping part 110 and the hook part can also be formed separately and then fixedly connected together, for example, by welding them together.

[0038] In this embodiment, as Figure 5 As shown, and in combination Figure 1 As shown, perpendicular to the axial direction of the pipe fitting, both sides of the clamping part 111 are provided with fixing ears 112; the hook part includes two hooks 120, which are respectively disposed above the two fixing ears 112. With this arrangement, firstly, the two hooks 120 have a stronger load-bearing capacity, and secondly, the two hooks 120 are respectively disposed on both sides of the clamping part 111, which makes the force applied by the pipe fitting connector 100 to the pipe fitting more balanced, and the pipe fitting and the pipe fitting connector 100 are less likely to be skewed, resulting in higher positional accuracy and better positional stability.

[0039] In this embodiment, as Figure 5 and Figure 6As shown, the hook 120 includes an integrally formed bent portion 121 and an extension portion 122. The bent portion 121 is integrally formed or fixedly connected to the fixing ear 112. The extension portion 122 is disposed at the end of the bent portion 121 away from the fixing ear 112 and extends downward in a direction gradually away from the fixing ear 112. In this configuration, the extension portion 122 of the hook 120 is obliquely positioned outward relative to the fixing ear 112, and the opening is relatively large, making it easier to hang the hook 120 on the hanging structure.

[0040] Specifically, in this embodiment, the included angle between the extension 122 and the fixing ear 112 is in the range of 8° to 10°. This angle range satisfies the need for convenient hanging without being too large, which would cause the hook 120 to fall off the hanging structure.

[0041] In this embodiment, the projection of the clamping part 111 is U-shaped in a plane perpendicular to the axial direction of the pipe.

[0042] In this embodiment, as Figure 5 As shown, one of the two fixing ears 112 has a circular through hole 113, and the other has an oblong through hole 114, with the length direction of the oblong through hole 114 perpendicular to the axial direction of the pipe fitting. Fasteners can pass through the circular through hole 113 and the oblong through hole 114 to fix the fixing ear 112 to the hanging structure. With this configuration, even if the gripping part 110 has deformation or manufacturing errors in the direction perpendicular to the axial direction of the pipe fitting, the oblong through hole 114 ensures that the pipe fitting fixing member is still fixed to the hanging structure.

[0043] In this embodiment, as Figures 1 to 4 As shown, the pipe fitting fixing device may further include a carrier connector 200, which forms a hanging structure for fixed connection with the target carrier. The carrier connector 200 is provided with a hanging groove, the hook portion can be hung on the groove wall, and the fixing ear 112 can be fixedly connected to the groove wall. In this configuration, when fixing the pipe fitting, the carrier connector 200 is fixed to the target carrier, the pipe fitting is fixedly connected to the pipe fitting connector 100, and finally the pipe fitting connector 100 is fixed to the carrier connector 200. That is, the pipe fitting connector 100 fixes the pipe fitting to the target carrier through the carrier connector 200. By setting the carrier connector 200 and providing structures on the carrier connector 200 that cooperate with the hook 120 and fixing ear 112 of the pipe fitting connector 100, the structural changes to the target carrier can be greatly reduced.

[0044] It should be noted that in other embodiments of this application, the pipe fixing device may also include only the pipe connector 100, which is directly fixed to the target carrier. Of course, in that case, the target carrier needs to have a corresponding structure that can hang the hook 120 and be fixedly connected to the fixing ear 112.

[0045] Specifically, in this embodiment, as Figure 2 As shown, the carrier connector 200 includes a mounting plate 210 and at least two spaced and oppositely arranged support plates 220. The mounting plate 210 and the support plates 220 together form a hanging groove, and the hook portion can be hung on the mounting plate 210. The side of the support plate 220 away from the mounting plate 210 can be fixed to the target carrier. In this configuration, when fixing the pipe connector 100 to the carrier connector 200, the hook 120 is first hung on the mounting plate 210, and then the fixing ear 112 is fixed to the mounting plate 210.

[0046] Specifically, in this embodiment, as Figure 2 As shown, a support plate 220 is provided on the left, right, and lower sides of the mounting plate 210. Each of the three support plates 220 has a fixing flange 230 on the side furthest from the mounting plate 210 for fixed connection with the target carrier. The three support plates 220 jointly support the mounting plate 210, providing more stable support; the fixing flanges 230 facilitate the fixing of the carrier connector 200 to the target carrier.

[0047] Specifically, in this embodiment, the following continues... Figure 2 As shown, the included angle between the support plate 220 and the mounting plate 210 is greater than or equal to 90°. Preferably, the included angle between the support plate 220 and the mounting plate 210 is greater than 90°. With this arrangement, the support plate 220 provides support not only in the direction perpendicular to the mounting plate 210 but also in the direction parallel to the mounting plate 210, making the entire carrier connector 200 more stable. In addition, the inclined arrangement of the support plate 220 expands the operating space when fixing the fixed flange 230, facilitating operation.

[0048] This embodiment also provides a heat pump water heater, including a housing 010 and a water tank 020 disposed within the housing 010. A water pipe 030 connected to the water tank 020 is fixed to the inner wall of the housing 010 by the aforementioned pipe fixing device. This heat pump water heater uses the aforementioned pipe fixing device to fix the water pipe 030, making it convenient to operate and highly efficient.
