Technical Field

The utility model relates to a domestic sewer pull throughs.

Background

At present, the dredging spring is adopted to dredge most of common household sewer dredging devices, the dredging springs are divided into a plurality of machines according to the thickness of the springs, the first common spring is the spring with the diameter of 20 millimeters, and the dredging device is suitable for dredging pipelines such as household buildings, kitchens and toilets. The sewer dredging tool that uses at present also has: the high-pressure water cleaning machine that the motor drove, the dredging machine that the drill bit that the motor drove creeps into accomplishes the mediation sewer, to the family use, the cost is expensive, uses not very conveniently.

Fig. 1 shows a dredging part of a simple sewer dredging tool which is currently commercially available.

The dredging tool has the following advantages and disadvantages.

(1) The advantage is simple and convenient easy to operate, can stretch into the downcomer that has the bend, is convenient for accomodate.

(2) The disadvantage is that the tool is inconvenient to clean the sewer. Mainly can not collect rubbish etc. in the pipeline when the spring withdraws from, if the pipeline is stifled real, this instrument more can't dredge, and the mediation is time-consuming and the effect is not good.

Disclosure of Invention

In order to solve the defects, the utility model provides a domestic sewer dredging device with simple structure, convenient operation, good dredging effect and low cost.

The utility model discloses a realize like this, a domestic sewer pull throughs, a serial communication port domestic sewer pull throughs include at least one section mediation spring, tunnelling drill bit, separation blade, go-between, handle and T type hand (hold) six parts.

The tunneling drill bit is of a cone structure, a spiral groove is formed in the wall surface of the tunneling drill bit, the tunneling drill bit can conveniently rotate inwards, four lifting lugs are uniformly distributed on the end surface, and threaded holes are formed in the connecting rod.

The separation blade is a fan-shaped structure without a sharp corner, and holes for connection are formed in the separation blade.

The rear end of the dredging spring is a first circular connecting block with a threaded hole for connection in the center, and the front end of the dredging spring is a second circular connecting block with a hollow stud in the center for connection; the diameter of first circular connecting block and second circular connecting block equals with mediation spring external diameter, and every section length of mediation spring can be different, can make up the use to the sewer of the different degree of depth.

The handle is provided with an anti-skid stripe groove, the handle is sleeved on the last section of dredging spring, and the raised ring end is arranged below and used for supporting the dredging spring to stably extend inwards.

The front end of the T-shaped handle is provided with threads which are in threaded connection with the dredging spring.

The utility model discloses a theory of operation: when the sewer is blocked, the dredging device is connected, the tunneling drill bit is firstly placed in the sewer, one hand holds the handle, when the tunneling drill bit touches a blocking object, the other hand presses the T-shaped handle and rotates the T-shaped handle in a specified direction, the tunneling drill bit is enabled to rotate forwards and spirally advance, when the tunneling drill bit is screwed downwards, the four separation blades are contracted and gathered together to stand up, when the tunneling drill bit penetrates through the blocking object, the separation blades extend and open under the action of gravity and resistance when the separation blades are pulled out, and the tunneling drill bit is pulled out outwards to take out garbage. When encountering a curved road, the dredging spring in the dredging device can be bent into the curved road to dredge the sewer.

The above technical scheme is adopted in the utility model, structural design is reasonable, enables ordinary mediation spring and tunnelling drill bit and freely turns to, makes it go forward through smoothly in complicated sewer to can let the tunnelling drill bit find the target pipeline of wanting the mediation and dredge work, mediation convenient and fast.

The utility model discloses simple structure, low in cost, convenient to use, mediation are effectual and the operating efficiency is high.

Detailed Description

The present invention is specifically described with reference to fig. 1 to 8, and can be implemented as follows: the household sewer dredging device is characterized by comprising at least one section of dredging spring 1, a tunneling drill bit 2, a baffle 3, a connecting ring 9, a handle 5 and a T-shaped handle 4.

The rear end of the dredging spring 1 is a first circular connecting block 6 with a threaded hole for connection in the center, and the front end of the dredging spring 1 is a second circular connecting block 7 with a hollow stud in the center for connection; the diameter of first circular connecting block 6 and second circular connecting block 7 equals with mediation spring 1 external diameter, and mediation spring 1 every section length can be different, through threaded connection to adapt to the sewer of the different degree of depth.

The heading drill bit 2 is of a cone structure, a spiral groove is formed in the wall surface of the heading drill bit, the heading drill bit can conveniently rotate inwards, four lifting lugs 10 which are uniformly distributed are arranged on the end surface of the heading drill bit, and a threaded hole 11 is formed in the connecting rod 8 and is in threaded connection with the dredging spring 1.

The baffle 3 is of a fan-shaped structure without a sharp corner, and the baffle 3 is provided with a hole for connection and is connected with the lifting lug 10 through a connecting ring 9.

The handle 5 is provided with an anti-skid stripe groove, the handle 5 is sleeved on the last section of dredging spring 1, and the end with a raised ring is arranged below and used for supporting the dredging spring to stably extend inwards.

The front end of the T-shaped handle 4 is provided with threads which are connected with the dredging spring 1 through threads.

When the dredging device is used, after all parts of the dredging device are connected, the tunneling drill bit 2 is firstly placed into a sewer, one hand holds the handle 5, when the dredging device touches a blocking object, the other hand presses the T-shaped handle 4 and rotates in a designated direction, so that the tunneling drill bit 2 rotates forwards and spirally advances, when the tunneling drill bit 2 rotates downwards, the four blocking pieces 3 are contracted and gathered together to stand up under the action of backward resistance, and when the tunneling drill bit 2 penetrates through the blocking object, the blocking pieces 3 extend and open under the action of gravity and pull-out resistance, and the tunneling drill bit 2 is pulled outwards to take out garbage.
