Description

Technical Field

[0001] The utility model belongs to the technical field related to control valves, and particularly relates to a fixing frame and a four-way reversing valve. Background Art

[0002] Four-way reversing valve is used in air-conditioning equipment to change the flow direction of refrigerant by changing the flow channel of refrigerant, thereby switching the functions of indoor and outdoor units of air-conditioning equipment in winter and summer.

[0003] At present, the four-way reversing valve is usually assembled at the corresponding position in the air-conditioning equipment by using a fixing frame to embrace the main valve body on the four-way reversing valve. In this process, the fixing frame is required to match the outer diameter size of the main valve body to meet the assembly requirements. Since a fixing frame of one specification can only be adapted to a four-way reversing valve of one specification size, the assembly of four-way reversing valves of different specifications and sizes in the air-conditioning equipment usually requires the development of fixing frames with different sizes, which increases the cost. Utility Model Content

[0004] In view of this, it is necessary to provide a fixing bracket for solving the above technical problems.

[0005] A fixing frame is used to fix the main valve body of a four-way reversing valve, and the fixing frame comprises:

[0006] A base, comprising a supporting portion, wherein the supporting portion is used to support the main valve body;

[0007] A fixing ring, cooperating with the base, and used for limiting the main valve body located on the supporting part to the base;

[0008] An adjusting sheet, detachably mounted on the supporting portion;

[0009] Wherein, the fixing frame has a first state and a second state; in the first state, the supporting portion is in contact with the main valve body; in the second state, the adjusting plate is located between the supporting portion and the main valve body, and the supporting portion is in contact with the main valve body through the adjusting plate.

[0010] It can be understood that, by utilizing the detachable installation arrangement of the adjusting plate on the supporting portion, the fixing frame can be directly adapted to main valve body structures of different specifications by installing and removing the adjusting plate in the fixing frame when directly supporting the main valve body. That is, the fixing frame can be adapted to the fixation of main valve bodies with different outer diameters, that is, the fixing frame can be adapted to the assembly of four-way reversing valves of different specifications and sizes in air-conditioning equipment, thereby improving the installation application range of the fixing frame and reducing costs.

[0011] In one embodiment, when the adjusting plate is located between the supporting portion and the main valve body, a second mounting surface is formed on the adjusting plate, the second mounting surface matches the outer peripheral surface of the main valve body, and the adjusting plate can support the main valve body through the second mounting surface.

[0012] It can be understood that the regulating plate supports the main valve body with a second mounting surface matched with the outer circumference of the main valve body. In this way, the contact area between the regulating plate and the main valve body can be increased, which has the effect of improving the stability of the regulating plate when supporting the main valve body.

[0013] In one embodiment, the second mounting surface is configured as an arc-shaped surface.

[0014] In one of the embodiments, a first mounting surface is formed on the support portion, the first mounting surface is used to match the outer peripheral surface of the main valve body, and the support portion can support the main valve body through the first mounting surface.

[0015] It can be understood that the support part uses a first mounting surface that matches the outer circumference of the main valve body to support the main valve body. In this way, the contact area between the support part and the main valve body can be increased when the support part supports the main valve body, which has the effect of improving the stability of the support part when supporting the main valve body.

[0016] In one embodiment, the first mounting surface is configured as an arc-shaped surface.

[0017] In one of the embodiments, a positioning buckle is formed on the adjusting plate, and a positioning groove is formed on the supporting portion; when the adjusting plate is abutted against the first mounting surface, the positioning buckle can engage with the positioning groove to limit the movement of the adjusting plate relative to the supporting portion along the circumference of the main valve body.

[0018] It can be understood that by utilizing the snap-fit ​​fit between the positioning buckle and the positioning groove, the adjustment plate can be restricted from moving along with the main valve body in the arc direction of the first mounting surface of the support portion, thereby further improving the stability of the adjustment plate when supporting the main valve body.

[0019] In one of the embodiments, a plurality of limit buckles are formed on the adjustment plate. When the adjustment plate is abutted against the first mounting surface of the support portion, the plurality of limit buckles can respectively abut against the support portion to limit the movement of the adjustment plate relative to the support portion along the width direction of the base.

[0020] It can be understood that by utilizing the abutment between multiple limit buckles and the support portion, the adjustment plate can be limited from moving relative to the support portion along with the main valve body in the width direction of the base, which can further improve the stability of the adjustment plate when supporting the main valve body.

[0021] In one embodiment, a boss is formed on the adjusting sheet, and when the adjusting sheet is abutted against the first mounting surface of the supporting portion, the boss at least partially abuts against the supporting portion;

[0022] The fixing bracket further comprises a fastener, and the fastener is used for fixing the boss to the supporting portion.

[0023] It is understandable that the connection between the boss and the support portion is achieved by fasteners to fix the adjustment sheet to the support portion when the adjustment sheet is abutted against the first mounting surface of the support portion. In this way, the matching structure between the adjustment sheet and the support portion can be simplified.

[0024] In one embodiment, a second mounting surface is formed on the adjusting plate, the second mounting surface is used to match the outer peripheral surface of the main valve body, and the adjusting plate can support the main valve body through the second mounting surface, and the adjusting plate is abutted against the first mounting surface of the supporting portion;

[0025] The projection length of the first mounting surface in the gravity direction is set to L 1 , the projection length of the second mounting surface in the gravity direction is set to L 2 , where L 1 ≥L 2 .

[0026] It can be understood that, through the above-mentioned structural setting, when the adjustment piece is abutted against the first mounting surface of the support part, the entire adjustment piece can be supported by the first mounting surface on the support part. In this way, the stability of the adjustment piece when assembled on the first mounting surface of the support part can be improved, and it is convenient to assemble the adjustment piece to the first mounting surface of the support part.

[0027] In one embodiment, the number of the support parts is two, and the two support parts are arranged at intervals along the width direction of the base;

[0028] The two supporting parts cooperate with each other and are used together to support the main valve body.

[0029] It is understandable that two support plates are used to support the main valve body. In this way, the thickness of the support plates can be reduced while ensuring that the support plates support the main valve body, thereby simplifying the structure.

[0030] In one embodiment, the fixing frame further comprises a support, and the two supporting parts are mounted on the support;

[0031] Wherein, the fixing ring part is arranged between the two supporting parts and is detachably connected to the support.

[0032] In addition, the present application also provides a four-way reversing valve, comprising the above-mentioned fixing frame

[0033] Due to the application of the above technical solution, the utility model has the following advantages compared with the prior art:

[0034] The fixing frame and the four-way reversing valve for which protection is sought in the present application utilize a detachable installation arrangement of an adjusting plate on a supporting portion, so that when the fixing frame directly supports the main valve body, the adjusting plate can be installed and removed in the fixing frame, so that the fixing frame can be directly adapted to main valve body structures of different specifications, that is, the fixing frame can be adapted to the fixing of main valve bodies with different outer diameters, that is, the fixing frame can be adapted to the assembly of four-way reversing valves of different specifications and sizes in air-conditioning equipment, thereby increasing the installation application range of the fixing frame and having the effect of reducing costs.

[0046] like Figure 6 As shown, the fixing frame 100 for which protection is requested in the present application is applied to the four-way reversing valve 200 to fix the main valve body 210 of the four-way reversing valve 200 so that the main valve body 210 can be assembled in the air conditioning equipment through the fixing frame 100 .

[0047] like Figure 1 , Figure 5 As shown, a fixing frame 100 provided in an embodiment of the present application includes a base 10, a fixing ring 20 and an adjusting plate 30. The base 10 includes a supporting portion 11, and the supporting portion 11 is used to carry a main valve body 210. The fixing ring 20 cooperates with the base 10 to limit the main valve body 210 located on the supporting portion 11 to the base 10. The adjusting plate 30 is detachably mounted on the supporting portion 11. The fixing frame 100 has a first state and a second state. In the first state, the supporting portion 11 is in contact with the main valve body 210. In the second state, the adjusting plate 30 is located between the supporting portion 11 and the main valve body 210, and the supporting portion 11 is in contact with the main valve body 210 through the adjusting plate 30. Here, the fixing ring 20 is detachably connected to the base 10, so that the main valve body 210 located on the supporting portion 11 is limited to the base 10 by the fixing ring 20.

[0048] It can be understood that the fixing frame 100 of the present application can choose to use the support part 11 to directly support the main valve body 210, or use the adjustment plate 30 on the support part 11 to support the main valve body 210, and then fix the main valve body 210 with the fixing ring 20, so that when the fixing frame 100 directly supports the main valve body 210, the adjusting plate can be installed and removed in the fixing frame 100, so that the fixing frame 100 can be directly adapted to the main valve body 210 structure of different specifications, that is, the fixing frame 100 can be adapted to fix the main valve body 210 with different outer diameters; in this way, the fixing frame 100 can be adapted to fix the main valve body 210 with different outer diameters, that is, the fixing frame 100 can be adapted to the assembly of four-way reversing valves 200 of different specifications and sizes in air-conditioning equipment, which has the effect of reducing costs. It should be noted that the fixing bracket 100 of the present application can also match the main valve bodies 210 of more sizes by replacing the adjustment sheets 30 of different thicknesses, which can further expand the types of four-way reversing valves 200 that the fixing bracket 100 can adapt to.

[0049] like Figure 1 , Figure 2 and Figure 5 As shown, in one embodiment, a first mounting surface 111 is formed on the support portion 11, and the first mounting surface 111 is used to match the outer peripheral surface 211 of the main valve body 210, and the support portion 11 can carry the main valve body 210 through the first mounting surface 111. In other words, when the support portion 11 directly carries the main valve body 210, the first mounting surface 111 on the support portion 11 can be used to contact the outer peripheral surface 211 of the main valve body 210 and support the main valve body 210, so that the contact area between the support portion 11 and the main valve body 210 when carrying the main valve body 210 can be increased, which has the effect of improving the stability of the support portion 11 when carrying the main valve body 210. Here, the first mounting surface 111 is set as an arc surface.

[0050] In this embodiment, there are two support parts 11, which are arranged at intervals along the width direction of the base 10; the two support parts 11 cooperate with each other and are used to carry the main valve body 210. In other words, the base 10 can use two support parts 11 to carry the main valve body 210, so that the thickness of the support part 11 can be reduced on the basis of ensuring the support of the main valve body 210, thereby simplifying the structure. Of course, in other embodiments, the number of support parts 11 can also be one, three, or even more, which will not be elaborated here.

[0051] like Figure 1As shown, in this embodiment, the fixing frame 100 also includes a support 12, and the two support parts 11 are both installed on the support 12; wherein, the fixing ring 20 is partially arranged between the two support parts 11 and is detachably connected to the support 12, so that the fixing ring 20 can embrace the main valve body 210 carried on the support part 11, and realize the limited fixation of the main valve body 210 on the support part 11. Here, the two ends of the fixing ring 20 can be specifically abutted against the support 12, and fixed to the support 12 by fastening structures such as screws and bolts (not shown in the figure), so that the fixing ring 20 can be easily fixed to the support 12. It should be noted that the fixing frame 100 can be specifically assembled in the air-conditioning equipment through the support 12 to realize the assembly of the four-way reversing valve 200 in the air-conditioning equipment.

[0052] like Figure 1 , Figure 5 As shown, in one embodiment, a second mounting surface 31 is formed on the adjusting piece 30, and the second mounting surface 31 is used to match the outer peripheral surface 211 of the main valve body 210, and the adjusting piece 30 can carry the main valve body 210 through the second mounting surface 31. That is to say, when the support portion 11 carries the main valve body 210 through the adjusting piece 30, the second mounting surface 31 on the adjusting piece 30 can be in contact with the outer peripheral surface 211 of the main valve body 210, and the main valve body 210 can be supported, so that the contact area between the adjusting piece 30 and the main valve body 210 when the adjusting piece 30 carries the main valve body 210 can be increased, which has the effect of improving the stability of the adjusting piece 30 when carrying the main valve body 210. Here, the second mounting surface 31 is set as an arc surface.

[0054] like Figures 1 to 4 As shown, in one embodiment, a positioning buckle 32 is formed on the adjusting piece 30, and a positioning groove 112 is formed on the supporting portion 11; when the adjusting piece 30 is abutted against the first mounting surface 111, the positioning buckle 32 can be engaged with the positioning groove 112 to limit the movement of the adjusting piece 30 relative to the supporting portion 11 along the circumference of the main valve body 210, so that the adjusting piece 30 can be limited to move along with the main valve body 210 in the arc direction of the first mounting surface 111 of the supporting portion 11, thereby further improving the stability of the adjusting piece 30 when the main valve body 210 is supported by the main valve body 210. Here, the positioning buckle 32 is arranged at the lowest position of the adjusting piece 30 and is arranged vertically downward relative to the adjusting piece 30, wherein the thickness and length of the positioning buckle 32 can be smaller than the size of the corresponding groove diameter on the positioning groove 112, so that the positioning buckle 32 can be easily inserted into the corresponding positioning groove 112, thereby facilitating the assembly of the adjusting piece 30 to the first mounting surface 111 of the supporting portion 11.

[0055] like Figure 4 As shown, in this embodiment, there are two positioning buckles 32, and the two positioning buckles 32 are arranged on both sides of the adjusting piece 30 along the center line direction of the second mounting surface 31 on the adjusting piece 30. Correspondingly, a positioning groove 112 is respectively provided on the two supporting parts 11, and the two positioning buckles 32 can be engaged with the corresponding positioning groove 112 at the same time, so that the stability of the adjusting piece 30 when limiting the arc direction of the first mounting surface 111 on the supporting part 11 can be improved. Here, the positioning buckle 32 and the adjusting piece 30 are set as an integrated structure.

[0056] like Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, a limiting buckle 33 is further formed on the adjusting piece 30. When the adjusting piece 30 is abutted against the first mounting surface 111 of the supporting portion 11, a plurality of limiting buckles 33 can respectively abut against the supporting portion 11 to limit the movement of the adjusting piece 30 relative to the supporting portion 11 in the width direction of the base 10. Here, the width direction of the base 10 specifically refers to the axial direction of the main valve body 210. A plurality of limiting buckles 33 are arranged on the outer sides of the two supporting portions 11. Each limiting buckle 33 can respectively abut against the corresponding supporting portion 11, so that the adjusting piece 30 can be limited to move relative to the supporting portion 11 in the width direction of the base 10 along with the main valve body 210, thereby further improving the stability of the adjusting piece 30 supporting the main valve body 210 when the adjusting piece 30 carries the main valve body 210.

[0057] like Figure 4 As shown, in this embodiment, there are four limit buckles 33, of which two limit buckles 33 are arranged on both sides of the positioning buckle 32 in the length direction of the support portion 11, and respectively abut against the corresponding support portion 11, so as to improve the stability of the adjustment piece 30 when limiting the position on the support portion 11 along the width direction of the base 10. Here, the limit buckle 33 is also set as an integrated structure with the adjustment piece 30.

[0058] like Figure 2 , Figure 3 As shown, in this embodiment, the projection length of the first mounting surface 111 on the support portion 11 in the gravity direction is set to L 1 The projection length of the second mounting surface 31 on the adjusting plate 30 in the gravity direction is set to L 2 , where L 1 ≥L 2In this way, when the adjusting piece 30 is assembled to the first mounting surface 111 of the supporting portion 11, the entire adjusting piece 30 can be supported by the first mounting surface 111 of the supporting portion 11. In this way, the stability of the adjusting piece 30 when assembled on the first mounting surface 111 of the supporting portion 11 can be improved, and it is convenient to assemble the adjusting piece 30 on the first mounting surface 111 of the supporting portion 11.

[0059] like Figure 5 As shown, in another embodiment, a boss 34 is formed on the adjusting piece 30, and when the adjusting piece 30 is abutted against the first mounting surface 111 of the supporting portion 11, the boss 34 at least partially abuts against the supporting portion 11; in addition, the fixing frame 100 further includes a fastener 40, and the fastener 40 is used to fix the boss 34 to the supporting portion 11. That is to say, when the adjusting piece 30 of this embodiment is assembled on the supporting portion 11, the fastener 40 can be used to connect the boss 34 and the supporting portion 11 to achieve connection. Here, the boss 34 is arranged at the lowest position of the adjusting piece 30 and is arranged vertically downward relative to the adjusting piece 30, wherein the number of the boss 34 is one, and the boss 34 can be specifically arranged on one side of the width direction of the adjusting piece 30.

[0060] In this embodiment, the fastener 40 is configured as a screw, a bolt, etc., and the fastener 40 is used to pass through the threaded connection between the boss 34 and the corresponding support portion 11 to achieve assembly limitation of the boss 34 on the corresponding support portion 11, so that the boss 34 can be easily fixed to the corresponding support portion 11.
