Abstract

The utility model relates to a height-adjusting structure for an inlet valve and an inlet pipe. More than two rows of uniform teeth are formed on the outside of a water inlet pipe with gaps, and the distance of the gaps between each row of teeth is bigger than the width of the teeth. A clamping ring is sheathed and arranged on the water inlet pipe, one section of inner threads is formed above the clamping ring, a ring clamping table is formed under the inner threads, and more than two rack grooves are formed on the clamping table with gaps. One section of outer threads is formed at the lower end of an outer sleeve, and the outer threads can be just screwed with the inner threads which are arranged on the clamping ring. One row of uniform teeth is also formed on T-shaped racks. The racks are hung and arranged on the outside of the water inlet pipe, clamped in the rack grooves of the clamping table of the clamping ring, and fixed through the screw connection of the inner and the outer threads of the clamping ring and the outer sleeve. The teeth which are arranged on the racks can be matched with the teeth which are arranged on the outside of the water inlet pipe. The utility model has the advantages of simple structure, easy processing manufacture and low cost.

Description

Water intake valve pipe height adjusting structure

The utility model belongs to toilet bowl attachment, and is relevant with water intake valve pipe height adjusting structure especially.

At present, the water intake valve pipe of the flush toilet of selling on the market mostly is unadjustable formula, the water tank of different size need be equipped with the water intaking valve of differing heights water inlet pipe, change when repairing at water intaking valve, need whole water inlet pipe is pulled down from water tank, this product is not only wide in variety, and inconvenience is installed, and maintenance is also inconvenient.Existing a kind of water inlet pipe is to adopt the adjustable diameter and screw adjusting height, as shown in Figure 5, by this sped structure, can regulate the height of water inlet pipe, and needn't pull down gutter changing when repairing, and is comparatively convenient.But this adjustment structure is had relatively high expectations on manufacturing process, and because of its adjustment structure is that the mode of helping pull a cart combines, for preventing to help pull a cart for a long time, overcoat is out of shape, and screw thread is difficult for processing too protrudingly; Because of threaded adjusting, screw thread easily is worn again, and for preventing to thread off, screw thread is difficult for too shallow again; So the product processing comparatively bothers, and cost is higher.

The purpose of this utility model is to provide a kind of water intake valve pipe height adjusting structure, and it not only can regulate the water inlet pipe height, and processing is easy, and cost is low.

For reaching above-mentioned purpose, solution of the present utility model is: the outer side clearance of water inlet pipe forms the above tooth uniformly of two rows, and the distance of being separated by between every toothrow is greater than the width of tooth; A collar is nested with on water inlet pipe, and collar top forms one section internal thread, and the internal thread below forms a circle Ka Tai, on the Ka Tai also the gap form rach slot more than two; The overcoat lower end forms one section external screw thread, just can with internal screw-thread screw on the collar; Also form the uniform tooth of a row on the T-shape tooth bar, tooth bar is taken and is put in the water inlet pipe outside, and is stuck in the card platform rach slot of collar, and the internal and external screw thread by collar, overcoat screws togather and fixes, and the tooth on the tooth bar just can cooperate with the tooth in the water inlet pipe outside.In addition, the same side of every toothrow all forms an edge on the water inlet pipe.

Adopt said structure, the utility model is by collar and overcoat stationary rack, and drives tooth bar and moving up and down between two toothrows on the water inlet pipe, when the water inlet pipe height is regulated when suitable, be about to overcoat and rotate to tooth bar and just cooperate, thereby reach the fixed water inlet pipe height with tooth on the water inlet pipe.The utility model is simple in structure, and processing is easy, and cost is also low.

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 3 is the utility model combination schematic diagram two;

Fig. 4 is a collar perspective view two;

Fig. 5 commonly uses product combination schematic diagram.

Consult Fig. 1, water inlet pipe 1 outer side clearance forms the above tooth 11 uniformly of two rows, and the same side of every toothrow 11 forms an edge 12, and the distance of being separated by between every toothrow 11 is greater than the width of tooth 11; A collar 2 is nested with on water inlet pipe 1, cooperates shown in Figure 4ly, and collar 2 tops form one section internal thread 21, and internal thread 21 belows form a circle card platform 22, on the card platform 22 also the gap form rach slot 23 more than two; Overcoat 3 lower ends form one section external screw thread 31, just can screw togather with internal thread 21 on the collar 2; Also form the uniform tooth 41 of a row on the T-shape tooth bar 4, tooth bar 41 is taken and is put in water inlet pipe 1 outside, and be stuck in card platform 22 rach slots 23 of collar 2, the internal and external screw thread 21,31 by collar 2, overcoat 3 screws togather and fixes, and the tooth on the tooth bar 4 41 just can cooperate with the tooth 11 in water inlet pipe 1 outside.

Cooperate shown in Fig. 2,3,4, if need to regulate water inlet pipe 1 height, being about to collar 2 rotations makes tooth bar 4 withdraw from from the tooth 11 on the water inlet pipe 1, by collar 2 and overcoat 3 stationary racks 4, drive tooth bar 4 and moving up and down between two toothrows 11 on the water inlet pipe 1, during to desired height, again with collar 2 rotations, tooth 41 on the tooth bar 4 is cooperated with tooth 11 on the water inlet pipe 1, reach the purpose of highly regulating.

Claims

1, a kind of water intake valve pipe height adjusting structure is characterized in that: the outer side clearance of water inlet pipe forms the above tooth uniformly of two rows, and the distance of being separated by between every toothrow is greater than the width of tooth; A collar is nested with on water inlet pipe, and collar top forms one section internal thread, and the internal thread below forms a circle Ka Tai, on the Ka Tai also the gap form rach slot more than two; The overcoat lower end forms one section external screw thread, just can with internal screw-thread screw on the collar; Also form the uniform tooth of a row on the T-shape tooth bar, tooth bar is taken and is put in the water inlet pipe outside, and is stuck in the card platform rach slot of collar, and the internal and external screw thread by collar, overcoat screws togather and fixes, and the tooth on the tooth bar just can cooperate with the tooth in the water inlet pipe outside.
