In order to achieve the above purposes, the technical scheme adopted by the application is as follows: the telescopic pipe sleeve of the sewage suction device comprises a corrugated pipe and a sleeving end, wherein the corrugated groove of the corrugated pipe is in a spiral line shape, the spiral line-shaped structure is easier to transmit torsional stress, and the telescopic pipe sleeve has more flexible rotation characteristics.

Preferably, the sleeve end is made of rubber material and has flexibility and wear resistance.

Preferably, the hook grooves are arranged in the inner wall of the sleeving end at equal intervals, so that the hooks are fixed more uniformly.

Preferably, the corrugated pipe is made of rubber materials, and the outer side surface and the inner wall of the corrugated pipe are provided with single-spiral corrugated grooves, so that the thickness of the pipe wall of the corrugated pipe is uniform.

Preferably, the inner wall of the sleeved end is provided with a butt joint fit groove suitable for being fit with a butt joint end on the sewage suction device.

Preferably, the outer side surface of the sleeved end is provided with a shrinkage groove to prevent fingers from slipping when the sleeved end is held.

Compared with the prior art, the beneficial effect of this application lies in:

(1) the corrugated groove on the corrugated pipe is designed into a spiral line structure, so that the pipe sleeve is easier to twist, and the flexibility of sewage suction operation is improved;

(2) through the both ends design rubber sleeve joint structure at the pipe box for the installation and the dismantlement of pipe box are all more convenient.

Detailed Description

The present application is further described below with reference to specific embodiments, and it should be noted that, without conflict, any combination between the embodiments or technical features described below may form a new embodiment.

In the description of the present application, it should be noted that, for the terms of orientation, such as "central", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., it indicates that the orientation and positional relationship shown in the drawings are based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, but does not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be construed as limiting the specific scope of protection of the present application.

It is noted that the terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.

The terms "comprises," "comprising," and "having," and any variations thereof, in the description and claims of this application, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

The sewage suction device telescopic pipe sleeve shown in fig. 1-5 comprises a sewage suction device telescopic pipe sleeve, which comprises a corrugated pipe 1 and a sleeve joint end 2, wherein the corrugated groove of the corrugated pipe 1 is in a spiral line shape, the corrugated pipe 1 is made of rubber materials, the outer side surface and the inner wall of the corrugated pipe 1 are respectively provided with a single spiral corrugated groove, and compared with a mutual circular corrugated groove, the spiral corrugated groove can better disperse the twisting stress to each repeating unit on the corrugated pipe 1 when being subjected to twisting action, and has better twisting adaptability.

The quantity of cup joint end 2 has two both ends of difference fixed connection at bellows 1, be used for fixing whole pipe box on the blow off pipe, cup joint end 2 is made by soft wear-resistant material, for example rubber materials commonly used just can have sufficient pliability and wearability well, the operation of turning up is conveniently cup jointed to end 2, the couple groove 202 has been seted up to the medial surface of cup joint end 2, the quantity in couple groove 202 has a plurality of, and a plurality of couple groove 202 are arranged at the inner wall equidistance of cup joint end 2, be used for with the couple cooperation on the soil pick-up pipe box butt joint end, place the pipe box and make a round trip to slide on the soil pick-up pipe.

The inner wall of the sleeve joint end 2 is provided with a butt joint conjunction groove 203 which is suitable for being in conjunction with the butt joint end on the sewage suction device, the outer side surface of the sleeve joint end 2 is provided with a contraction groove 201 which prevents the finger from slipping when the sleeve joint end 2 is held, and particularly when the sleeve joint end 2 is fixed, the sleeve joint end 2 is more conveniently pushed to be in clamping connection with the pipe sleeve butt joint end on the sewage suction device.

The installation mode of the sewage suction device telescopic pipe sleeve is as follows: before the sewage suction device is used for the first time, the pipe sleeve needs to be installed, the sewage suction pipe is connected to a pump machine of the sewage suction device at first, then the pipe sleeve is sleeved outside the sewage suction pipe, one end of the pipe sleeve is fixed with a butt joint end on the pump machine through a sleeving end 2, then one end of the sewage suction pipe, far away from the pump machine, is exposed out of the pipe sleeve and is connected with a suction head, and finally one end of the pipe sleeve, far away from the pump machine, is clamped with the suction head through the sleeving end 2, so that the sleeve can be installed and used; in the using process, the pipe sleeve can absorb most of scratches and impacts, so that the sewage suction pipe in the pipe sleeve can work stably, and the sewage leakage caused by the fact that the sewage suction pipe is scratched needs to be worried, and meanwhile, the sewage suction pipe can rotate more freely and the sewage suction operation is easier and more flexible because the corrugated pipe 1 of the pipe sleeve is of a spiral structure; when the sleeve pipe needs to be disassembled and cleaned, the rubber sleeve end 2 is turned outwards only by fingers, and the hook of the fixed sleeve end 2 can be separated from the hook groove 202, so that the sleeve pipe can be disassembled and cleaned relative to the sewage suction pipe in a free movement mode.

The foregoing has described the general principles, essential features, and advantages of the application.
