Description

Sealing clamp for water inlet and outlet pipes of washing machine

Technical Field

The utility model relates to the technical field of clamps, in particular to a sealing clamp for a water inlet pipe and a water outlet pipe of a washing machine.

Background

The joint between the water inlet pipe and the water outlet pipe of the household washing machine and the equipment needs to be provided with a clamp so as to seal the joint. The water inlet pipe and the water outlet pipe of the household washing machine are mostly provided with corrugated hoses, so that the hoses are easy to vibrate when the washing machine works. In order to improve the locking degree of the clamp and prevent the clamp from loosening caused by long-term vibration of the hose, a plurality of structural improvements are carried out on the clamp in the prior art. For example, the publication No. CN206669176U discloses a water inlet and drain clamp for a washing machine, which comprises a clamp main body and a clamping ring, wherein the clamp main body is in a ring shape with an opening in the middle, the opening is provided with the clamping ring, and the clamping ring and the corresponding end of the clamp main body are fastened to realize the locking of the clamp. The structure has the following disadvantages: the main body of the clamp and the clamping ring are buckled to form a complete ring, and the deformation quantity is inconsistent due to different materials of the two parts in the using process, so that the attaching degree of the deformed ring structure to the pipe wall is reduced, and the problem of looseness of a joint is caused; in addition, the main body of the clamp is composed of a steel wire, the contact area of the main body of the clamp and the pipe wall is limited, and under the conditions of machine vibration or torsion and the like, stress concentration is easy to occur, so that the surface of the pipe wall, particularly the surface of the hose, is damaged. The patent with publication number CN212056264U discloses a clamp for the water inlet pipe of the outer tub of the drum washing machine, which improves the part of the locking bolt, but the problem of the above mentioned deformation amount is still present because the material of the adopted fixing seat is different from that of the main body of the clamp for fixing the bolt.

Detailed Description

The following describes embodiments of the present invention with reference to the drawings.

As shown in fig. 1, the sealing clamp for the water inlet pipe and the water outlet pipe of the washing machine of the embodiment includes a steel strip 1, the steel strip 1 is circular, and the steel strip 1 is sequentially provided with a first section 12, a first connecting part 11, a middle section 14 and a second connecting part 13 along a circumferential direction;

the first connecting part 11 is an outwards bent U-shaped bulge, the second connecting part 13 is an outwards bent limiting frame, and the outer side surface of the tail end of the first section 12 is attached to the inner side surface of the tail end of the middle section 14 to form a closed circular ring;

still include bolt 2, the fixed one end of bolt 2 is connected through its screw hole with the U-shaped arch, and 3 threaded connection of free one end and nut of bolt 2, nut 3 set up in spacing frame.

The limiting frame is provided with a first side wall 131, a second side wall 132 and a third side wall 133 which are sequentially connected, the first side wall 131 is connected with the middle section 14, the inner surface of the first side wall 131 is completely attached to the inner end face of the nut 3, the second side wall 132 is perpendicular to the first side wall 131, the inner surface of the second side wall 132 is attached to the outer peripheral face of the nut 3, the third side wall 133 is perpendicular to the second side wall 132, and the third side wall 133 is partially attached to the outer end face of the nut 3; through holes are correspondingly formed in the first side wall 131 and the third side wall 133, the nuts 3 are limited in the limiting frame, and the through holes are used for penetrating through the bolts 2 in threaded fit with the nuts 3.
