[0029] In order to make the purpose, technical scheme and advantages of the utility model more clear, the utility model will be described further in detail below in combination with the drawings. Only this statement, the up, down, left, right, front, back, inside, outside and other directions of the utility model appearing or about to appear in the text, only with the drawings of the utility model as the base, it is not the specific limitation of the utility model.
[0030] Referring to Figures 1-5 The utility model discloses a drainage pipe connecting head mounting structure, including base 1 and connecting head 2, the base 1 is equipped with connecting hole 11, the connecting hole 11 inner side wall is equipped with notch 12.
[0031] The connecting head 2 includes pipe body 21 and the limiting rib for being located at the outer side wall of pipe body 21, the limiting rib includes first limiting rib 22 and second limiting rib 23, and the first limiting rib 22 and the second limiting rib 23 are sequentially arranged in the axial direction of pipe body 21.
[0032] The pipe body 21 is arranged on the connecting hole 11, and the first limiting rib 22 passes through the notch 12 to make the wall of the base 1 be located between the first limiting rib 22 and the second limiting rib 23, and the pipe body 21 is rotated to make the first limiting rib 22 and the second limiting rib 23 be clamped on the base 1 respectively.
[0033] The utility model discloses a drainage pipe connecting head mounting structure is provided with first limiting rib and second limiting rib on pipe body, and the pipe body is arranged on the connecting hole of base, and makes first limiting rib and second limiting rib be located on the two sides of the wall of base respectively. The pipe body is rotated, and first limiting rib and second limiting rib are clamped on the base respectively, so that the connecting head can not be separated from the base, thereby realizing the installation of the connecting head. The structure makes the installation of the connecting head not need to use screw, and can be completed without using tool, and the installation is simple, and the structure is simple, and the connection is reliable.
[0034] The user passes the pipe body outwardly through the connecting hole from the base, and then rotates the pipe body so that the first limiting rib is away from the connecting hole, preventing the first limiting rib from moving reversely through the connecting hole and causing the pipe body to fall out of the connecting hole. The wall of the base is embedded between the first limiting rib and the second limiting rib. When the connecting head moves inwardly to the base, the first limiting rib will be clamped on the wall of the base, and when the connecting head moves outwardly to the base, the second limiting rib will be clamped on the wall of the base. Thus, through the cooperation of the first limiting rib and the second limiting rib, the pipe body is fixed in the connecting hole, and the connecting head is fixed on the base.
[0035] Specifically, a preset distance is left between the first limiting rib 22 and the second limiting rib 23, which is slightly less than or equal to the thickness of the wall of the base 1, avoiding that there is too large a gap between the base, the first limiting rib and the second limiting rib, so that the pipe body is loose, and the connection between the base and the connecting head is reliable and the installation is stable.
[0036] Preferably, the first limiting rib 22 and the second limiting rib 23 are arranged in a staggered manner in the circumferential direction of the pipe body 21, on the one hand to balance the force on both ends of the pipe body, and on the other hand to prevent the second limiting rib from passing through the gap, ensuring that the first limiting rib and the second limiting rib are respectively placed on both sides of the wall of the base.
[0037] Preferably, as shown in Figure 2 , 4 -5, a limiting block 14 for limiting the rotation of the pipe body 21 in one direction is arranged on the outer wall of the base 1; the first limiting rib 22 can interfere with the limiting block 14 to limit the rotation of the pipe body. Specifically, the "one direction" refers to the counterclockwise direction. As shown in Figure 4 , when the pipe body is rotated in the counterclockwise direction, the first limiting rib will interfere with the limiting block, and the limiting block limits the movement of the first limiting rib, i.e. limits the continuous rotation of the pipe body, avoiding that the first limiting rib returns to the position corresponding to the gap and causes the pipe body to disengage from the connecting hole.
[0038] Preferably, as shown in Figure 3 , 5 , a limiting buckle 25 for limiting the rotation of the pipe body 21 in another direction is arranged on the second limiting rib 23; a limiting hole 13 is arranged on the base 1, and the limiting buckle 25 can be clamped in the limiting hole 13. Specifically, the "another direction" refers to the clockwise direction. As shown in Figure 5 , when the pipe body is rotated in the counterclockwise direction, in addition to the interference of the first limiting rib with the limiting block, the limiting buckle on the second limiting rib will fall into the limiting hole. The limiting buckle and the limiting hole cooperate to limit the second limiting rib, so that the pipe body cannot be rotated in the clockwise direction.
[0039] At this time, under the cooperation of the limiting block and the limiting buckle, the pipe body cannot rotate counterclockwise or clockwise, and is fixed on the base in the circumferential direction. The cooperation of the first limiting rib and the second limiting rib fixes the pipe body on the base in the axial direction. Thus, the connector can be reliably fixed on the base, and has simple structure and convenient installation.
[0040] More preferably, as shown in Figure 3 The second limiting rib 23 is provided with a limiting arm 24 extending outwardly from the second limiting rib 23, and the limiting buckle 25 is arranged on the free end of the limiting arm 24. Specifically, the limiting buckle 25 extends from the free end of the limiting arm 24 to the direction of the first limiting rib 22, i.e. to the direction of the wall of the base 1. The second limiting rib 23, the limiting arm 24 and the limiting buckle 25 are integrally formed and are made of plastic. The limiting arm has a certain elasticity. When the second limiting rib is clamped on the wall of the base, the limiting arm is elastically deformed due to the limiting of the limiting buckle by the wall of the base, until the limiting buckle falls into the limiting hole, and the limiting arm returns to its original position, so that the limiting buckle is clamped on the base.
[0041] Preferably, as shown in Figure 3 The number of the first limiting ribs 22 is at least two, and they are symmetrically arranged with the center of the pipe body 21. The number of the second limiting ribs 23 is at least two, and they are symmetrically arranged with the center of the pipe body 21. More preferably, the center lines of the adjacent first limiting ribs 22 and second limiting ribs 23 form an angle of 90 degrees, further balancing the force on the connector and the base, and making the installation of the connector reliable and stable. The notches 12 and the first limiting ribs 22 are arranged one by one.
[0042] Preferably, as shown in Figure 2 , 4 The side wall of the base 1 is provided with a tightening block 15 arranged outside the connecting hole 11. The first limiting rib 22 can abut against the tightening block 15 to push the first limiting rib 22 away from the base 1. When the first limiting rib moves to the tightening block, with the rotation of the pipe body, the first limiting rib will move to the upper surface of the tightening block and abut against the tightening block, so that the first limiting rib is elastically deformed to generate a pre-tightening force, thereby tightly clamping the wall of the base by the first limiting rib and the second limiting rib, further enhancing the reliability and stability of the connection between the connector and the base.
[0043] More preferably, as shown in Figure 2 , 4As shown, the tightening block 15 is provided with a guide slope 151. The guide slope makes the first limiting rib more easily move to the upper surface of the tightening block, so that the installation is simple and labor-saving. Under the guidance of the guide slope, the first limiting rib can smoothly move to the upper surface of the tightening block, and the pre-tightening force is generated due to the interference between the tightening block and the first limiting rib, so that the base wall is clamped.
[0044] Preferably, the number of the tightening blocks 15 is the same as that of the first limiting ribs 22. The tightening blocks are symmetrically arranged with the center of the connecting hole.
[0045] Correspondingly, the utility model also discloses a washing machine, the washing machine is equipped with the drain pipe connector mounting structure such as any one of claims 1-9. The specific structure of the drain pipe connector mounting structure is as described above, and will not be repeated here.
[0046] In summary, the utility model provides a drain pipe connector mounting structure and washing machine, and installation is simple, and connection is reliable.
[0047] The above is the preferred embodiment of the utility model, and it should be pointed out that for ordinary skilled persons in the art, without departing from the principle of the utility model, a number of improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the utility model.
