Abstract
The invention provides a pipeline strainer which comprises a case, a movable handle, a square rod, a front end clamping groove, a rear end clamping groove, a gear, a front pawl and a rear pawl. The gear, the front pawl and the rear pawl are arranged in the case. The movable handle is movably connected with the gear in the case through the rear pawl. The front pawl is connected with the tail of the case. The front end clamping groove is formed in one end of the case. The case and the front end clamping groove are fixedly connected. The rear end clamping groove is formed in the tail of the square rod. A rack is arranged on the upper portion of the square rod. The gear is meshed with the rack. The pipeline strainer has the advantages of being simple in structure, low in manufacturing cost, easy to operate, good in performance, convenient to carry and high in efficiency, and saving time and labor.
Description
Technical field
The present invention relates to a kind of take-up device, especially relate to a kind of pipeline strainer.
Background technology
At present, connection between the pipe fitting of various pipes under normal circumstances or between sheet material has unreliability, in order to overcome difficulties, in work progress, need the booster action of various strainer, at present, in the course of the work, the strainer complex structure of use, operation inconvenience, inefficiency, is inconvenient to carry, poor practicability.
Summary of the invention
The object of this invention is to provide that a kind of structure is simple, cost of manufacture is low, simple to operate, operating efficiency is high, the pipeline strainer be convenient for carrying.
Technical scheme of the present invention is: comprise housing, flexible handle, square bar, front end draw-in groove, rear end draw-in groove, be arranged on the gear of enclosure interior, front ratchet, rear ratchet, flexible handle is flexibly connected with the gear of enclosure interior by rear ratchet, and front ratchet is connected with housing afterbody, and one end of housing is provided with front end draw-in groove, for being fixedly connected with between housing with front end draw-in groove, the afterbody of square bar is provided with rear end draw-in groove, and square bar top is provided with tooth bar, and gear is engaged mutually with tooth bar.
The advantage that the present invention has and good effect are: owing to adopting technique scheme, structure is simple, preparation cost is low, simple to operate, time saving and energy saving, functional, be convenient for carrying, and operating efficiency is high.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is elaborated.
As shown in Figure 1-2, a kind of pipeline strainer, comprise housing 4, flexible handle 1, square bar 6, front end draw-in groove 5, rear end draw-in groove 7, be arranged on the gear 2 of housing 4 inside, front ratchet 9, rear ratchet 3, flexible handle is flexibly connected by the gear 2 of rear ratchet 3 with housing 4 inside, front ratchet 9 is connected with housing 4 afterbody, one end of housing is provided with front end draw-in groove 5, for being fixedly connected with between housing 4 with front end draw-in groove 5, the afterbody of square bar 6 is provided with rear end draw-in groove 7, and square bar top is provided with tooth bar 8, and gear 2 and tooth bar 8 are engaged mutually.
The course of work of this example: when commencing operation, adjusts to stretchable maximum position by strainer, rotates clockwise flexible handle 1, is rotated by rear ratchet 3 driven gear 2, housing 4 and front end draw-in groove 5 is moved right, completes a cinching process; When regaining tension space, rotate counterclockwise flexible handle 1, rear ratchet 3 exits, and front ratchet 9 blocks gear 2, and gear 2 remains static, and repeats cinching process, thus reaches final effect.
Above one embodiment of the present of invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
