[0045] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0046] In the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0047] The present application embodiment provides a connection structure, such as Figures 1 to 7 As shown, the connection structure 1 comprises: a first body 11 and a second body 12 that can be bendably connected, a connection portion 13 for bending is formed between the first body 11 and the second body 12; the second body 12 has a first buckle 121 adjacent to the connection portion 13 and a second buckle 122 away from the connection portion 13, the first body 11 has a first abutment portion matched with the first buckle 121 and a second abutment portion 112 matched with the second buckle 122; wherein, when the second body 12 is buckled on the first body 11, a locking space for fixing the tubular member is formed between the first body 11 and the second body 12. Exemplarily, Figure 1 The connection structure is shown in the open state. Figure 5 The connection structure is shown in a snap-on state.

[0048] Here, the tubular member to be fixed may be a water pipe, a cable, etc., and this application does not make any specific limitation on this.

[0049] Here, since the first body 11 and the second body 12 are connected via the bendable connecting portion 13, the second body 12 can be buckled on the first body 11 under the action of external force through the cooperation between the first buckle 121 and the first abutting portion and the cooperation between the second buckle 122 and the second abutting portion 112 to lock the tubular member. Similarly, the second body 12 can be opened under the action of external force, so that the first buckle 121 is separated from the first abutting portion and the second buckle 122 is separated from the second abutting portion 112, thereby unlocking the connection between the second body 12 and the first body 11 to release the locking of the tubular member. In this way, locking or unlocking can be performed by bending operation, which is convenient in operation compared with the existing collar locking or one-way locking of the harness tie, and is easy to disassemble and reuse.

[0050] In actual applications, there is often a risk of breakage due to repeated bending of the connecting portion 13. In the embodiment of the present application, a double-clip connection method is adopted, that is, the first clip 121 cooperates with the first abutment portion, and the second clip 122 cooperates with the second abutment portion. Therefore, even if the connecting portion 13 breaks, the connection between the first body 11 and the second body 12 is reliable due to the cooperation between the first clip 121 and the first abutment portion and the cooperation between the second clip 122 and the second abutment portion 112. The tubular member can also be effectively locked, effectively avoiding the locking failure of the tubular member caused by the breakage of the connecting portion 13.

[0051] In some embodiments, Figure 1As shown, the first buckle 121 includes: a first upright section 1211 and a first buckle section 1212, the first buckle section 1212 extends from the first upright section 1211 in a direction toward the connecting portion 13, and a first step portion 1213 is formed between the bottom end surface of the first buckle section 1212 and the side wall surface of the adjacent first upright section 1211. The first abutting portion is a first groove 111 opened in the area adjacent to the connecting portion 13 of the first body 11 for accommodating the first buckle section 1212, and a second step portion 1111 for abutting against the first step portion 1213 is formed at the first groove 111.

[0052] Under the action of external force, when the second body 12 is buckled with the first body 11, Figure 7 As shown, the first snap-fit ​​section 1212 extends into the first groove 111, and the first step portion 1213 abuts against the second step portion 1111, that is, when the first snap-fit ​​section 1212 tilts upward in the first groove 111, it will be subjected to the downward pressure exerted by the second step portion 1111 on the first step portion 1213, thereby achieving effective positioning between the end of the adjacent connecting portion 13 on the first body 11 and the end of the adjacent connecting portion 13 on the second body 12, avoiding connection failure caused by breakage of the connecting portion 13, thereby enhancing the reliability of the connection.

[0053] In some embodiments, Figure 1 As shown, the second buckle 122 includes: a second upright section 1221 and a second buckle section 1222, the second buckle section 1222 extends from the second upright section 1221 in a direction away from the connecting portion 13. The second abutting portion 112 includes: a third upright section 1121 and a third buckle section 1122, the third buckle section 1122 extends from the third upright section 1121 in a direction toward the connecting portion 13, and a receiving area 1123 for abutting the second buckle section 122 is formed between the bottom end surface of the third buckle section 1122 and the side wall surface of the adjacent third upright section 1121.

[0054] Under the action of external force, when the second body 12 is buckled with the first body 11, Figure 7 As shown, the second buckling section 1222 will be locked in the accommodating area 1123 , so that the end of the second body 12 away from the connecting portion 13 can be locked by the end of the first body 11 away from the connecting portion 13 .

[0055] It can be understood that when the first snap-on section 1212 of the second body 12 is locked in the first groove 111 and the second snap-on section 1222 of the second body 12 is locked in the accommodating area 1123, both ends of the second body 12 are effectively fixed to the first body 11. Even if the connecting portion 13 between the first body 11 and the second body 12 is broken, since both ends of the second body 12 are effectively fixed, the locking space formed between the first body 11 and the second body 12 can still effectively lock the tubular member.

[0056] In some embodiments, the end of the second buckle section 1222 forms a first hook 1222B, and the end of the third buckle section 1122 forms a second hook 1122A that cooperates with the first hook 1222B. In this way, when the second buckle section 1222 is locked in the accommodating area 1123, the connection reliability between the first body 11 and the second body 12 can be further enhanced based on the engagement of the first hook 1222B with the second hook 1122A.

[0057] It can be understood that when the tubular member in the locking space formed between the first body 11 and the second body 12 expands outward under the action of thermal expansion stress, the bite force between the first hook 1222B and the second hook 1122A increases, which will make the connection between the first body 11 and the second body 12 more reliable. In this way, the self-locking effect of the connecting structure 1 on the internal tubular member can be achieved, that is, the tubular member cannot be easily separated from the lock of the connecting structure 1 under the action of external force or pulling, which is conducive to ensuring the effective locking of the tubular member. It can be suitable for tubular member locking scenarios under the influence of external forces such as certain vibrations, such as the locking scenario of the water inlet pipe of a washing machine, to avoid the locking failure of the water inlet pipe due to the vibration of the chassis during the dehydration process.

[0058] In some embodiments, the outer surface of the second buckling section 1222 forms a first guide section 1222A with an inclined or arc transition; the outer surface of the second hook 1122A forms a second guide section that cooperates with the first guide section 1222A. It can be understood that the cooperation between the first guide section 1222A and the second guide section on the outer surface of the second hook 1122A facilitates the second buckling section 1222 to slide easily into the accommodating area 1123, thereby achieving the engagement of the first hook 1222B with the second hook 1122A.

[0059] It is understandable that when the first hook 1222B is engaged with the second hook 1122A, the connection structure 1 can self-lock the tubular member in the locking space. If unlocking is required, the second body 12 needs to be pressed down first to disengage the first hook 1222B from the second hook 1122A, and then force is applied in the direction of opening the second body 12, that is, the second body 12 is bent outward at the connection portion 13. In this way, the locking failure of the connection structure 1 caused by the misoperation of the external force can be avoided, thereby further improving the locking reliability of the connection structure 1.

[0060] In some embodiments, the inner wall surface of the first body 11 and the inner wall surface of the second body 12 are both roughly semicircular, so that the outer wall surface of the tubular member can be closely attached to the inner wall surface of the locking space, which is more conducive to locking the tubular member.

[0061] In some embodiments, the inner wall surface of the first body 11 is provided with an arc-shaped and outwardly convex first rib 113 along the circumferential direction; and / or the inner wall surface of the second body 12 is provided with an arc-shaped and outwardly convex second rib 123 along the circumferential direction. In this way, the clamping effect of the inner wall surface of the locking space on the tubular member can be enhanced to prevent the tubular member from shaking.

[0062] Exemplarily, the tubular member is a drain pipe of a washing machine, and the drain pipe is a corrugated tube structure. The inner wall surface of the first body 11 is circumferentially provided with an arc-shaped and outwardly convex first rib 113, and the inner wall surface of the second body 12 is circumferentially provided with an arc-shaped and outwardly convex second rib 123. When the second body 12 is buckled on the first body 11, the first rib 113 and the second rib 123 cooperate to form an annular rib, which can be embedded in the corrugated pattern of the drain pipe, thereby enhancing the clamping effect on the drain pipe and avoiding shaking of the drain pipe.

[0063] In some embodiments, the first surface of the connecting portion 13 along the bendable direction is provided with a second groove 131 and / or the second surface is provided with a third groove 132. Figure 1 As shown, a second groove 131 is formed on the upper surface of the connecting portion 13, and a third groove 132 is formed on the lower surface of the connecting portion 13, so that the thickness of the connecting portion 13 becomes thinner and can be bent under the action of external force, so as to facilitate the second body 12 to be engaged with the first body 11 or to be detached from the first body 11 to switch the state.

[0064] In some embodiments, the connection portion 13 is further provided with a reinforcing rib 133 for enhancing the connection strength. By providing the reinforcing rib 133, the fracture of the connection portion 13 can be effectively avoided. Here, the reinforcing rib 133 can be provided at the second groove 131 and / or the third groove 132, and the number of the reinforcing rib 133 can be one or more, which is not specifically limited in the present application.

[0065] In some embodiments, the connection structure 1 further includes: a positioning seat 14 connected to the first body 11. Here, the positioning seat 14 is used to be fixed to the mounting platform so that the tubular member can be locked to the mounting platform. The positioning seat 14 can be a flat plate, sheet, tubular, etc. structure, which is not specifically limited in this application.

[0066] In some embodiments, the first body 11 , the second body 12 and the connecting portion 13 are integrally formed by injection molding or sheet metal molding.

[0067] Here, the first body 11, the second body 12 and the connecting portion 13 can be plastic parts or foam parts formed by injection molding, or sheet metal parts formed by sheet metal, so that the manufacturing process can be simplified and the reliability of the connection can be enhanced. It is understandable that the positioning seat 14 can also be formed in one piece with the first body 11, the second body 12 and the connecting portion 13.

[0068] The present application also provides a washing device, such as Figure 4 and Figure 6 As shown, it includes: a base 2 and a connection structure 1 of the present application embodiment fixed on the base 2. Here, the base 2 can be the base of a washing machine, and the first body 11 in the connection structure 1 is fixed to the base 2 via a positioning seat 14. The locking space formed when the first body 11 and the second body 12 are buckled together is used to lock the drain pipe, so that the drain pipe can be effectively fixed on the base 2.

[0069] It should be noted that the technical solutions described in the embodiments of the present application can be combined arbitrarily without conflict.

[0070] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
