Description
Technical field
The invention relates to the electric pipe cutter that field of power tools is cut for tubing, particularly the fast lockign apparatus of electric pipe cutter head.
Background technology
Electric pipe cutter is a kind of pipe cutting equipment being widely used in the industries such as petrochemical industry, water supply distribution, factory's plumbing, fire-fighting, hot-water heating civil engineering, it comprises power cutting device, base assembly, pipe clamping device, power cutting device is movably articulated on base assembly, have simple and reasonable, easy for operation, be fixedly clamped reliable, the feature such as cutting accuracy is high, otch flatness is good, operating efficiency is high, tubing waste is little, Pipe installing is convenient.But in use also there is following problem in existing electric pipe cutter: owing to generally fixing with hand trip bolt when existing power cutting device and base assembly lock, inconvenient operation, performance is unreliable, considerably increases the labour intensity of workman, and directly affects operating efficiency.For this reason, many manufacturers and knowledgeable people are studied for the problems referred to above and develop, but not yet have more rational product to emerge so far.
Summary of the invention
For overcoming the above-mentioned defect that existing electric pipe cutter exists, the object of the invention is to provide a kind of simple and reasonable, easy for operation, working stability is reliable, result of use good, operating efficiency is high electric tube cutter head fast lockign apparatus.
The invention solves the problems of the technologies described above adopted technical scheme, it comprises left and right handle, head assembly, base assembly, locking mechanism, described locking mechanism comprises push button, pull bar, sector gear, reduction torsion spring, tooth bar tapered end, locking backer, push button is slidably disposed on the top of left and right handle, sector gear is hinged on the bottom of left and right handle by reduction torsion spring, pull bar one end is hinged on push button, the other end is hinged on sector gear, tooth bar tapered end to be slidably disposed on the left and right handle below sector gear and to engage with sector gear, locking backer to be arranged on base assembly and to be provided with locking draw-in groove, the head of tooth bar tapered end stretches out left and right handle and matches with the locking draw-in groove on locking backer.
The further scheme of the invention, described left and right handle is fixed on head assembly, head assembly by rocking lever and base assembly hinged.
The further scheme of the invention, described tooth bar tapered end is provided with chute, and the chute of tooth bar tapered end is provided with anterior-posterior balance slide-bar, and anterior-posterior balance slide-bar correspondence is fixed on the handle of left and right.
After adopting said structure, compared with prior art have the following advantages and effect: because sector gear is hinged on left and right handle by reduction torsion spring, tooth bar tapered end to be slidably disposed on below sector gear and to engage with sector gear, push button is connected with sector gear by pull bar, when down locking by left and right handle, because tooth bar tapered end contacts with locking backer, sector gear is driven to rotate while tooth bar tapered end retraction, the energy storage of reduction torsion spring pressurized, when tooth bar tapered end goes downwards to locking draw-in groove position, under the elastic force effect of reduction torsion spring, fan-shaped gear driven tooth bar tapered end automatic spring inserts in locking draw-in groove, thus reach the object automatically locking head assembly.When driven forward push button unlocks, push button drives sector gear to rotate by pull bar, and sector gear drives tooth bar tapered end bounce back after overcoming the elastic force of reduction torsion spring and exit locking draw-in groove, and head assembly can rise.To lock or unlocking operation is simple and convenient, speed is fast, efficiency is high, stable and reliable for performance.
Accompanying drawing explanation
Fig. 1 is the decomposition texture schematic diagram of the invention.
Fig. 2 is the structural representation of the invention.
Wherein about 1 handle, 2 jointed shafts, 3 balance slide-bars, 4 reduction torsion springs, 5 sector gears, 6 tooth bar tapered ends, 7 chutes, 8 pull bars, 9 connecting pins, 10 push buttons, 11 head assemblies, 12 rocking levers, 13 base assemblies, 14 locking backers, 15 locking draw-in grooves.
Detailed description of the invention
Shown in Fig. 1 and Fig. 2, for the specific embodiments of a kind of electric tube cutter head of the invention fast lockign apparatus, it comprises left and right handle 1, head assembly 11, base assembly 13, locking mechanism, described left and right handle 1 is fixed on head assembly 11, head assembly 11 is hinged by rocking lever 12 and base assembly 13, described locking mechanism comprises push button 10, pull bar 8, sector gear 5, reduction torsion spring 4, tooth bar tapered end 6, locking backer 14, push button 10 is slidably disposed on the top of left and right handle 1, sector gear 5 is hinged on the bottom of left and right handle 1 by jointed shaft 2, jointed shaft 2 is arranged with reduction torsion spring 4, reduction torsion spring 4 makes sector gear 5 keep one to rotate clockwise strength, pull bar 8 one end is hinged on push button 10 by connecting pin 9, the other end is hinged on sector gear 5 by connecting pin, tooth bar tapered end 6 to be slidably disposed on the left and right handle 1 below sector gear 5 and to engage with sector gear 5, locking backer 14 to be arranged on base assembly 13 and to be provided with locking draw-in groove 15, the head of tooth bar tapered end 6 stretches out left and right handle 1 and matches with the locking draw-in groove 15 on locking backer 14.
In order to ensure that tooth bar tapered end 6 is installed simply, it is light flexibly to stretch, described tooth bar tapered end 6 is provided with chute 7, and the chute 7 of tooth bar tapered end 6 is provided with anterior-posterior balance slide-bar 3, and anterior-posterior balance slide-bar 3 correspondence is fixed on left and right handle 1.
The invention course of work is as follows, when head assembly 11 needs to lock, hold left and right handle 1 and down press, contact with locking backer 14 top when tooth bar tapered end 6 starts, tooth bar tapered end 6 bounces back and passes through engagement and drives sector gear 5 counterclockwise to rotate, the energy storage of reduction torsion spring 4 pressurized; When tooth bar tapered end 6 goes downwards to locking draw-in groove 15 position, reduction torsion spring 4 releases energy and drives sector gear 5 to rotate clockwise, sector gear 5 drives tooth bar tapered end automatic spring to insert in locking draw-in groove 15 by engagement, thus reaches the object automatically locking head assembly 11.When head assembly 11 needs to rise unblock, finger driven forward push button 10, push button 10 drives sector gear 5 counterclockwise to rotate by pull bar 8, now reduction torsion spring 4 pressurized energy storage, sector gear 5 drives tooth bar tapered end 6 straight line retraction by engagement and exits from locking draw-in groove 15, and head assembly 11 completes unblock and can rise.
The above; just the specific embodiment of the invention, not makes any pro forma restriction, on the technical scheme basis not departing from the invention to the invention; done simple modification, equivalent variations or modification, all fall into the protection domain of the invention.
