Preferably, every spacing draw-in groove all includes wide oral area and slot portion, wide oral area lateral wall is equipped with the chamfer, be equipped with the chamfer on the elasticity jack catch.

Preferably, the depth of the wide opening part is smaller than that of the narrow opening part, and a guide slope is arranged at the joint of the wide opening part and the narrow opening part.

Preferably, the sidewall of the overflow pipe lock catch is provided with an opening.

Preferably, the drain valve base outer wall is equipped with the lug, be equipped with the lockhole on the overflow pipe hasp, the lockhole makes overflow pipe hasp and drain valve base joint with the lug cooperation.

Preferably, the upper end surface of the bump is an inclined surface.

Preferably, the lower end of the adjustable overflow pipe is provided with a sealing ring, and the adjustable overflow pipe is sealed with the drain valve base in an interference fit manner through the sealing ring.

Preferably, the sealing ring is provided in plurality.

The invention has the beneficial effects that:

the invention provides a detachable and adjustable overflow pipe, which can be freely adjusted in height and can generate obvious pause and frustration in the adjusting process, can realize quick installation and positioning to a required size, effectively solves the problems, saves labor cost, shortens production period and provides possibility for secondary adjustment of a user in the using process.

In the figure: 1. the adjustable overflow pipe comprises an adjustable overflow pipe, 2 parts of an overflow pipe lock catch, 3 parts of a drainage valve base, 4 parts of a limiting clamping groove, 5 parts of a sealing ring, 6 parts of a narrow opening part, 7 parts of a wide opening part, 8 parts of a guide slope, 9 parts of a chamfer, 10 parts of an elastic clamping jaw, 11 parts of a lock hole, 12 parts of an opening part and 13 parts of a lug.

Detailed Description

In order to make the technical solutions of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.

As shown in the figures, the present invention comprises: drain valve base 3, the overflow pipe hasp 2 on the drain valve base is located to the cover and passes the overflow pipe hasp and stretch into the adjustable overflow pipe 1 in the drain valve base, adjustable overflow pipe lower extreme and drain valve base inner wall are sealed and adjustable overflow pipe along drain valve base up-and-down motion of interference fit, adjustable overflow pipe outer wall is equipped with a plurality of spacing draw-in grooves 4 on length direction, be equipped with the elasticity jack catch 10 that corresponds on the overflow pipe hasp, open the elasticity jack catch, stimulate adjustable overflow pipe from top to bottom can change the height of overflow pipe as required, block the locking that spacing draw-in groove can realize the overflow pipe height with elasticity jack catch card, easy operation, convenient to use connects firmly.

Preferably, every spacing draw-in groove all includes wide oral area 7 and narrow mouth portion 6, wide mouth lateral wall is equipped with chamfer 9, be equipped with the chamfer on the elasticity jack catch, rotate adjustable warning pipe, when the wide oral area was gone into to elasticity jack catch card, the adjustable warning pipe of upper and lower pulling can make the elasticity jack catch outwards open along the chamfer, it is higher convenient to adjust the warning pipe height from top to bottom, the purpose that the elasticity jack catch was equipped with the chamfer guarantees that adjustable warning pipe easily adjusts when cooperating with adjustable warning pipe, and has obvious pause and frustrate when pulling adjustable warning pipe from top to bottom, make things convenient for operating personnel to fix a position fast and install needs size, when the narrow oral area was gone into to the elasticity jack catch card, because the narrow mouth lateral wall does not have the chamfer, can't pull adjustable warning pipe and change its height, can realize the locking.

Preferably, the depth of the wide opening part is smaller than that of the narrow opening part, a guide slope is arranged at the joint of the wide opening part and the narrow opening part, and when the elastic clamping jaw is shifted from the narrow opening part to the wide opening part, the elastic clamping jaw is pre-opened under the action of the guide slope, so that the adjustable overflow pipe is pulled more laborsavingly.

Preferably, the lateral wall of the overflow pipe lock catch is provided with an opening part 12, so that cracking or damage caused by overlarge deformation when the overflow pipe lock catch is installed is effectively avoided.

Preferably, the outer wall of the drain valve base is provided with a convex block 13, the overflow pipe lock catch is provided with a lock hole 11, and the lock hole and the convex block are matched to enable the overflow pipe lock catch to be clamped with the drain valve base.

Preferably, the upper end face of the lug is an inclined plane, so that the overflow pipe is conveniently locked and installed on the drainage valve base.

Preferably, the lower end of the adjustable overflow pipe is provided with a sealing ring, the adjustable overflow pipe is sealed with the drain valve base in an interference fit manner through the sealing ring, and the structure can effectively play a role in sealing and prevent water seepage when being matched with the drain valve base.

Preferably, the sealing ring is provided in plurality.

The invention provides a detachable and adjustable overflow pipe, which can be freely adjusted in height and can generate obvious pause and frustration in the adjusting process, can realize quick installation and positioning to a required size, effectively solves the problems, saves labor cost, shortens production period and provides possibility for secondary adjustment of a user in the using process
