[0024] The following is combined with Figure 1-4 The embodiments of the present utility model are described in detail.
[0025] Example 1
[0026] Traditional refrigerant diverter pipes are usually connected to other branch pipes by welding at the diversion point. However, welding means that when the refrigerant diverter pipe fails, it is not possible to replace only the refrigerant diverter pipe, but the refrigerant diverter pipe and the pipes connected to it need to be replaced together, resulting in material waste.
[0027] The technical solution adopted by the utility model is: a refrigerant configuration splitter pipe, such as Figure 4 As shown, it includes a first tube body 1, a second tube body 2 and a connecting structure 3, wherein the connecting structure 3 is used to connect the first tube body 1 and the second tube body 2. Figure 1As shown, the connection structure 3 includes an inner sleeve 31, an outer sleeve 32 and a connection assembly, wherein the side wall of the outer sleeve 32 is provided with a clamping opening 321; the clamping opening 321 extends from one end of the outer sleeve 32 to the other end of the outer sleeve 32; the outer sleeve 32 is sleeved outside the inner sleeve 31; the connection assembly includes a locking section 322 and a connector 4, the locking section 322 is arranged on the outer wall of the outer sleeve 32, and two locking sections 322 are arranged on both sides of the clamping opening 321 respectively; the connector 4 is connected to the locking section 322, and the connector 4 is used to drive the two locking sections 322 to move closer to or away from each other. It can be understood that the distance between the two locking sections 322 is changed, thereby changing the diameter of the outer sleeve 32, thereby squeezing the inner sleeve 31, and finally squeezing the first tube body 1 and the second tube body 2 penetrating the inner sleeve 31, so that the first tube body 1 and the second tube body 2 are tightly connected to the inner sleeve 31.
[0028] In this embodiment, when the first tube body 1 and the second tube body 2 on the refrigerant shunt pipe need to be connected, the connection can be directly achieved through the connecting structure 3. The inner sleeve 31 is preferably a rubber ring with elastic deformation ability, and the inner sleeve 31 and the outer sleeve 32 have the same length, that is, the end faces of the inner sleeve 31 at both ends of the axial direction are flush with the end faces of the outer sleeve 32 at both ends of the axial direction.
[0029] In one embodiment, if the diameters of the first tube body 1 and the second tube body 2 are small, after the first tube body 1 and the second tube body 2 are sleeved in the inner sleeve 31, the two locking sections 322 on the outer sleeve 32 are brought close to each other. During the approaching process, since the inner sleeve 31 is subjected to the radial squeezing force of the outer sleeve 32, the inner sleeve 31 also applies radial force to the first tube body 1 and the second tube body 2 until the first tube body 1 and the second tube body 2 are tightly fitted to the inner sleeve 31.
[0030] In another possible implementation, for reference, if the diameters of the first tube body 1 and the second tube body 2 are larger, the two locking sections 322 on the outer sleeve 32 are first moved away from each other until the inner sleeve 31 is adapted to the first tube body 1 and the second tube body 2, and then the two locking sections 322 on the outer sleeve 32 are moved closer to each other, and then the above-mentioned extrusion operation is repeated until the desired tight fit is achieved.
[0031] For reference, the above-mentioned connection structure 3 can not only realize the tight connection of two pipe bodies, but also adapt to pipe bodies of different diameters, with a wide range of applications and high flexibility.
[0032] Example 2
[0033] Considering that the connection structure 3 is used to connect the refrigerant shunt pipe, the inner sleeve 31 made of rubber material is prone to hardening and brittleness or even surface corrosion after long-term contact with refrigerant such as Freon, thereby affecting its sealing performance. Therefore, after the first tube body 1 and the second tube body 2 are sleeved in the inner sleeve 31, gas may escape from the connection between the first tube body 1 and the inner sleeve 31 or the connection between the second tube body 2 and the inner sleeve 31, resulting in an inability to achieve an effective sealing connection. Therefore, based on Example 1, as Figure 1 and 2 As shown, both ends of the outer sleeve 32 are provided with limit plates 5 , the limit plates 5 are arranged around the axis of the outer sleeve 32 , and the inner sleeve 31 is located between the two limit plates 5 .
[0034] For reference, the limit plate 5 is circumferentially arranged around the end of the outer sleeve 32, and the two limit plates 5 located at the two ends of the outer sleeve 32 are arranged opposite to each other. The limit plate 5 and the outer sleeve 32 are combined to form a structure similar to a "door" type. Compared with the case where there is no limit plate 5, the gas can directly escape along the gap between the inner wall of the inner sleeve 31 and the outer wall of the tube body. After the limit plate 5 is set, the gas will be blocked by the limit plate 5 when escaping to the end, which plays a certain sealing role.
[0035] In addition, in order to prevent the outer wall of the limiting plate 5 and the outer sleeve 32 from being uneven and affecting the aesthetics of the entire connection structure, the outer wall of the limiting plate 5 and the outer wall of the outer sleeve 32 are in the same plane. The limiting plate 5 and the outer sleeve 32 can be fixedly connected by welding or fusion, or can be movably connected by plugging or screwing.
[0036] Example 3
[0037] Considering the fit between the stop plate 5 and the inner sleeve 31, the sealing is further achieved, such as Figure 2 As shown, a limiting groove 51 is provided on one side of the limiting plate 5 close to the outer sleeve 32, and a groove wall 511 of the limiting groove 51 corresponds to an inner wall of the outer sleeve 32; it can be understood that the limiting groove 51 is located on the side of the limiting plate 5 facing the inner sleeve, and the inner wall of the limiting groove 51 and the inner wall of the outer sleeve 32 are in the same plane, so that the outer wall of the inner sleeve 31 is tightly fitted with the inner wall of the limiting groove 51 of the outer sleeve 32.
[0038] The groove bottom 512 of the limiting groove 51 abuts against the inner sleeve 31. In other words, the limiting groove 51 wraps the inner sleeve 31. It should be noted that the material of the limiting groove 51 is consistent with that of the outer sleeve 32.
[0039] Example 4
[0040] Considering the fit between the limiting groove 51 and the inner sleeve 31, the sealing is further achieved, as well as the smoothness of the outer surface of the entire connecting structure 3. Figure 2 As shown, an arc segment 513 is provided between the groove wall 511 and the groove bottom 512, and the arc segment 513 is bent in a direction away from the inner sleeve 31. It can be understood that when the inner sleeve 31 made of rubber material is squeezed, the volume of the inner sleeve 31 will increase and extend toward the groove wall 511 until it abuts against the groove wall 511. The two ends of the arc segment 513 are respectively connected to the groove wall 511 and the groove bottom 512, and the arc segment 513 is adapted to the outer edge of the end surface of the inner sleeve 31.
[0041] In this embodiment, both ends of the inner sleeve 31 abut against the groove bottom 512 of the limiting groove 51, the outer wall of the inner sleeve 31 fits against the groove wall 511 of the limiting groove 51, and the arc section 513 of the limiting groove 51 matches the outer edge of the end surface of the inner sleeve 31. When the first tube body 1 and the second tube body 2 are inserted into the inner sleeve 31, the outer wall of the inner sleeve 31 extends toward the bottom wall of the limiting groove 51, the groove wall 511 and the inner wall of the outer sleeve 32. When the connector 4 drives the two locking members to approach each other, the outer sleeve 32 and the limiting groove 51 jointly squeeze the inner sleeve 31, so that the inner sleeve 31 squeezes the first tube body 1 and the second tube body 2 to achieve a sealed connection.
[0042] Example 5
[0043] The connection between the limiting plate 5 and the outer sleeve 32 may be a movable connection such as plugging, or a fixed connection such as welding. In this embodiment, the limiting plate 5 and the outer sleeve 32 are preferably an integrated structure.
[0044] Example 6
[0045] Considering that the inner sleeve 31 is in contact with the refrigerant for a long time, cracks are likely to appear, so that the internal refrigerant escapes from the cracks. Figure 3 As shown, the connection structure 3 further includes a telescopic ring 33, which is located between the inner sleeve 31 and the outer sleeve 32. It can be understood that the outer wall of the telescopic ring 33 fits with the inner wall of the outer sleeve 32, and the inner wall of the telescopic ring 33 fits with the outer wall of the inner sleeve 31. The telescopic ring 33 is an open ring structure, and the telescopic ring 33 is used to seal the inner sleeve 31 and the outer sleeve 32.
[0046] For reference, the expansion ring 33 is an annular ring with an opening. The existence of the opening makes the diameter of the expansion ring 33 not fixed, and can change with the diameter of the outer sleeve 32 to adapt to tubes of different sizes. In addition, when cracks appear in the inner sleeve 31, the refrigerant will be blocked by the expansion ring 33 when escaping from the cracks, which further makes it difficult for the refrigerant to escape.
[0047] Example 7
[0048] To further achieve sealing, the end face of the telescopic ring 33 is flush with the end face of the inner sleeve 31. It is understandable that the axial length of the telescopic ring 33 is equal to the axial length of the inner sleeve 31, so that when the outer sleeve 32 squeezes the telescopic ring 33, the telescopic ring 33 can be fully fitted with the inner sleeve 31.
[0049] Example 8
[0050] like Figure 1 , 3 As shown in 4, the locking section 322 extends in a direction away from the outer sleeve 32; a fixing hole is provided on the locking section 322; the connecting member 4 includes a screw rod 41 and a locking nut 42; the screw rod 41 is passed through the fixing hole, the nut abuts against a side of the locking section 322 away from the clamp 321, and the nut is threadedly connected to the screw rod 41.
[0051] In this embodiment, the connecting member 4 is a screw rod 41 and a locking nut 42. This is because the screw rod 41 and the locking nut 42 can easily adjust the distance between the two locking sections 322, and are easy to replace even if damaged. In addition, in order to better achieve locking and sealing, multiple locking nuts 42 can also be set, and all of them can realize this technical solution.
[0052] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
