Description

Technical Field

[0001] The utility model relates to the technical field of reversing valves, and more specifically, to a guide frame structure and a reversing valve. Background Art

[0002] The reversing valve is an essential component in the temperature-changing system of an air conditioner. The reversing valve in the prior art includes a valve body, a piston assembly, a slider, and a guide frame structure. The guide frame structure is usually composed of a frame body and a bending plate formed by bending a sheet metal. The guide frame structure is installed in the valve body, the slider is installed on the guide frame structure, and the piston assembly is connected to the frame body through the bending plate and can push the guide frame structure to move in the valve body.

[0003] When there is an abnormal pressure difference in the air-conditioning system, due to the insufficient connection strength between the bending plate and the frame body, the bending plate may deform relative to the frame body, resulting in the piston being stuck, and further resulting in the situation that the reversing valve does not reverse.

[0004] In order to overcome the above problems, in the prior art, a reinforcing member is usually additionally provided between the bending plate and the frame body to improve the connection strength and anti-bending ability at the connection position between the bending plate and the frame body. However, the reinforcing member in this method is usually a separately processed component, which is installed between the bending plate and the frame body through assembly components such as screws. The installation process is complex, the cost is high, and the enhancement effect on the connection strength is limited. Summary of the Utility Model

Such a setting is beneficial to selecting the stamping and bending forming conditions of the reinforcing member according to the actual situation.

[0011] Further, the bending part further includes reinforcing ribs, and the reinforcing ribs are arranged at the connection between the bending plate and the frame body. Such a setting further improves the connection strength between the bending plate and the frame body.

[0012] Further, there are multiple reinforcing ribs, and the multiple reinforcing ribs are spaced apart. Such a setting facilitates ensuring the reliability of enhancing the connection strength at the connection between the bending plate and the frame body according to the actual situation.

[0013] Further, the reinforcing ribs are formed by stamping on the inner side of the connection position between the bending plate and the frame body, and a stamping groove is correspondingly formed on the outer side of the connection position between the bending plate and the frame body. Such a setting facilitates the processing of the reinforcing ribs.

[0014] Further, the dimension of the reinforcing ribs in the width direction of the frame body is 1.5 mm to 2.5 mm. Such a setting is beneficial to ensuring the reliability of the reinforcing ribs in enhancing the connection strength.

[0015] Further, two bending parts are provided at each end of the frame body, and the bending directions of the two bending plates at the same end are opposite, and the two reinforcing members are respectively connected to the two side surfaces.

[0016] According to another aspect of the present invention, a reversing valve is provided, and the reversing valve includes the above-mentioned guide frame structure.

[0017] Applying the technical solution of the present invention, a guide frame structure is provided, which includes a frame body and a bending part arranged at the end of the frame body.

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way limits the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0038] As Figures 1 to 5 shown, the embodiment of the present invention provides a guide frame structure, including a frame body 10 and a bending part 20 provided at the end of the frame body 10. The end of the frame body 10 has an end face and two parallel side faces. The end face is located between the two side faces and the three are sequentially connected along the outer peripheral direction of the frame body 10; the bending part 20 includes a reinforcing member 22 and a bending plate 21 perpendicular to the frame body 10. The bending plate 21 and the frame body 10 are of an integral structure and are formed at the end face of the frame body 10. The reinforcing member 22 and the bending plate 21 are of an integral structure and are formed on one side of the bending plate 21 facing one of the side faces of the frame body 10. The reinforcing member 22 is connected to the side face of the corresponding side of the frame body 10.

[0039] In this embodiment, the bending plate 21 and the frame body 10 are of an integral structure and the reinforcing member 22 and the bending plate 21 are of an integral structure, which is convenient for the integral molding of the guide frame structure. It is not necessary to separately process the reinforcing member 22 and perform additional installation, which is beneficial to simplifying the installation process, saving the installation cost and improving the processing efficiency. Further, by transferring the bending plate 21 and the frame body 10 through the reinforcing member 22, the force transmission and dispersion of the frame body 10 can be realized, the connection strength between the bending plate 21 and the frame body 10 is improved, and the connection position between the bending plate 21 and the frame body 10 is not easily deformed or broken. Furthermore, the anti-bending and anti-impact performances of the bending plate 21 are improved, which is beneficial to ensuring the reliability and stability of the application of the guide frame structure.

[0040] Specifically, the frame body 10 and the bending part 20 in this embodiment are integrally formed by stamping and bending. Further, in order to ensure the strengthening effect of the reinforcing member 22 on the connection strength between the bending plate 21 and the frame body 10, after the reinforcing member 22 is bent and formed, it is fixedly connected to the side surface of the frame body 10. The preferred connection method is welding. The reinforcing member 22 and the frame body 10 are connected into one body by welding, so as to ensure the anti-deformation or anti-fracture strengthening of the bending plate 21.

[0041] In Embodiment 1 as shown in Figure 1 and Figure 2 the reinforcing member 22 is a rectangular plate-like structure with a triangular shape. Such a setting facilitates the integral stamping and bending of the reinforcing member 22 and the bending plate 21, and at the same time is beneficial to ensuring the strengthening effect of the reinforcing member 22 on the connection strength between the bending plate 21 and the frame body 10.

[0042] It can be understood that the shape of the reinforcing member 22 and the like can be adaptively adjusted according to the actual situation during forming. For example, in Embodiment 2 as shown in Figures 3 to 5 the reinforcing member 22 is a rectangular plate-like structure with a rectangular shape.

[0043] In this embodiment, the plate-like reinforcing member 22 is arranged perpendicular to the frame body 10 and the bending plate 21, which is beneficial to ensuring the force transmission and dispersion effect on the frame body 10, preventing stress concentration, and further ensuring the strengthening effect of the reinforcing member 22 on the connection strength between the frame body and the bending plate 21.

[0044] It can be understood that in other embodiments not shown in the figures, the plate-like reinforcing member 22 can form a certain angle with the frame body 10, and / or the plate-like reinforcing member 22 can form a certain angle with the bending plate 21, not limited to the perpendicular setting in this embodiment, and will not be exemplified one by one here.

[0045] Specifically, in this embodiment, a first connection area is formed at the connection between the reinforcing member 22 and the frame body 10, and a second connection area is formed at the connection between the bending plate 21 and the frame body 10. The first connection area and the second connection area are connected. Such a setting is beneficial to ensuring the strengthening effect of the reinforcing member 22 on the connection strength between the frame body and the bending plate 21.

[0046] It can be understood that in other embodiments not shown in the figures, the first connection area and the second connection area are spaced apart to avoid the situation that the transitions of the reinforcing member 22, the frame body 10, and the bending plate 21 are prone to interference or difficult to bend during bending.

[0047] In Figure 1 and Figure 2In the first embodiment shown, the bent portion 20 further includes a reinforcing rib 23, and the reinforcing rib 23 is disposed at the connection between the bent plate 21 and the frame body 10. With this arrangement, the connection strength at the connection between the bent plate 21 and the frame body 10 is further enhanced by the reinforcing rib 23 (by more than about 20%), avoiding deformation or fracture of the bent plate 21 and ensuring the reliability and stability of the application of the guide frame structure.

[0048] It can be understood that the arrangement of the reinforcing rib 23 in the first embodiment and the arrangement of the reinforcing rib 23 in the second embodiment can be as Figures 6 to 8 in the third embodiment of Figure 9 or as shown in the fourth embodiment of Figure 10 or as shown in the fifth embodiment.

[0049] In the third embodiment as shown in Figures 6 to 8 two bent portions 20 are provided at each end of the frame body 10, the bending directions of the two bent plates 21 at the same end are opposite, and the two reinforcing members 22 are respectively connected to the two side surfaces. With this arrangement, the reliability of the application of the guide frame structure in the reversing valve is ensured.

[0050] It can be understood that the number of the reinforcing ribs 23 can be adjusted to multiple according to the actual situation, and the multiple reinforcing ribs 23 are arranged at intervals. For example, in Figure 9 the fourth embodiment shown, two reinforcing ribs 23 are provided at the connection between the bent plate 21 and the frame body 10. With this arrangement, it is beneficial to ensure the reliability of enhancing the connection strength at the connection between the bent plate 21 and the frame body 10 according to the actual situation.

[0051] Specifically, the reinforcing rib 23 is formed by stamping on the inner side of the connection position between the bent plate 21 and the frame body 10, and a stamping groove 24 is correspondingly formed on the outer side of the connection position between the bent plate 21 and the frame body 10. With this arrangement, it is beneficial to reduce the processing difficulty of the reinforcing rib 23 and facilitate the rapid processing and forming of the reinforcing rib 23.

[0052] In this embodiment, the reinforcing rib 23 is a block structure with a triangular or quasi-triangular cross-section, and the dimension of the reinforcing rib 23 in the width direction of the frame body 10 is 1.5 mm to 2.5 mm. By limiting the minimum width of the reinforcing rib 23, it is beneficial to ensure the reliability of enhancing the connection strength, avoiding the situation that the effect of enhancing the connection strength is not obvious due to too small a width or affecting the structural strength of the bent plate 21 due to too large a width. It should be noted that the above width range of the reinforcing rib 23 is a preferred range and can be adjusted adaptively according to the actual situation.

[0053] It can be understood that, as in Figure 10In the fifth embodiment shown, the stamping height of the reinforcing rib 23 (which can also be understood as the depth of the stamping groove 24) can be adjusted according to the actual situation, as long as there is an obvious bulge on the inner side and the minimum width of the reinforcing rib 23 is within the above range.

[0054] Another embodiment of the present utility model provides a reversing valve. The reversing valve includes the above-mentioned guide frame structure. The reversing valve further includes a valve body, a piston assembly and a slider. The guide frame structure is installed in the valve body, the slider is installed on the guide frame structure, and the piston assembly is connected to the frame body 10 through a bending plate 21 and can push the guide frame structure to move in the valve body. In this embodiment, by providing a reinforcing member 22 and a reinforcing rib 23, the connection strength at the connection between the bending plate 21 and the frame body 10 is enhanced, avoiding the situation that the frame body 10 is easily lifted under the action of water hammer during the use of the reversing valve, so that the connection between the frame body 10 and the bending plate 21 where the piston assembly is located is prone to yield deformation, and ensuring the reliability and stability of the application of the reversing valve.

[0055] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or their combinations.

[0056] Unless otherwise specifically stated, the relative arrangements of the components and steps, numerical expressions and values set forth in these embodiments do not limit the scope of the present utility model. At the same time, it should be understood that for the convenience of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationship. Technologies, methods and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods and devices should be regarded as part of the specification. In all the examples shown and discussed here, any specific value should be interpreted as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0057] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of the present utility model; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0058] For the convenience of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "upper" etc. can be used here to describe the spatial positional relationship between a device or feature shown in the drawings and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation other than the orientation described in the drawings for the device. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "over other devices or structures" will then be positioned as "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding explanations should be made for the spatial relative descriptions used here.

[0059] In addition, it should be noted that using words such as "first", "second", etc. to limit the components is only for the convenience of distinguishing the corresponding components. Without additional statement, the above words have no special meaning. Therefore, it should not be construed as a limitation on the protection scope of the present utility model.
