Abstract

The utility model relates to a marking tool for engineering construction, particularly a switching type scriber ink fountain used for construction parts, such as building sites, carpentry manufacture, stone processing, etc., to mark and take benchmarks. The utility model is characterized in that a coil is arranged in a casing body, a spring is arranged in the coil, the outer diameter of the coil is wound with a pull wire and the other end of the pull wire is connected with a needle body fixing piece. A deformed cam is fixed on a central shaft in the coil, the front end surface of the deformed cam is connected with a turntable, the front end surface of the turntable is provided with a cam level, and the central shaft of the back end surface of the turntable is sheathed with a deformed spline, an ink box is fixed in the casing body and is positioned at the right side of the coil and a needle mouth piece is arranged in the right port of the casing body. The utility model has the advantages of novel structure and convenient use, the ink box is in a seal structure, indian ink in the ink box is not easy to volatilize and pour out and a sponge does not need pressing fixedly by a finger. After the indian ink in the ink box is run out, ink change is convenient, the pull wire convolves back automatically after marking is finished and a datum line is easily eliminated through adopting the needle body fixing piece.

Description

The suitching type ink fountain

[technical field]

The utility model relates to the scoring tool in the engineering construction, is a kind of suitching type ink fountain that benchmark is got in construction part line such as construction site, carpenter's making, processing of stone that is used for specifically.

[background technology]

The existing line to construction part looked for the ink fountain of benchmark, generally is made up of coil and print cartridge, and print cartridge is built-in with the material that holds black sponge or cotton yarn and so on, and backguy is passed from the print cartridge middle part, catches prepared Chinese ink in the backguy in order to the stria that stretches tight out on the needs material processed.Existing print cartridge is a uncovered, in use has very big defective: at first, for prepared Chinese ink is fully caught in backguy, when backguy was passed, the carpenter often needed to push down with finger the material of interior sponge of print cartridge and so on, like this prepared Chinese ink finger of will making dirty; Secondly, the prepared Chinese ink in the print cartridge is easy to volatilization and inclines to, and is very inconvenient when carrying; After having rule, also need hand traverse line wheel that line is regained, the ink fountain of this structure brings very big inconvenience to the carpenter when using undoubtedly.

[summary of the invention]

The utility model provides a kind of suitching type ink fountain in order to overcome above-mentioned defective, and print cartridge is a hermetically-sealed construction, and the prepared Chinese ink in the print cartridge is not easy to volatilization and inclines to, also need not push down sponge with finger, and, after the prepared Chinese ink in the print cartridge uses up, it is very convenient to change China ink, after having rule, and the automatic rollback of backguy.

For achieving the above object, design a kind of suitching type ink fountain, comprise housing, print cartridge, coil, backguy, rotating disk, the needle body fixture is formed, it is characterized in that enclosure interior is equipped with coil, coil inside is provided with clockwork spring, coil outer diameter is wound with backguy, the backguy other end connects the needle body fixture, the distortion cam is fixed on the coil inside central shaft, and distortion cam front end face connects rotating disk, and the rotating disk front end face is provided with cam lever, the central shaft of rotating disk rear end face is with the distortion spline, print cartridge is fixed on the inside of housing, is positioned at the right side of coil, and housing right output port inside is provided with pin mouth spare; Said needle body fixture is made up of needle guard, needle body, spring, rotor plate, and needle guard inside has circular hole, is provided with needle body in the circular hole, is with spring on the needle body, and the right-hand member of needle guard connects rotor plate; Print cartridge is that closed structure and inside are cavity, and the print cartridge rear end face is provided with presses black device.

Housing (3) inside can also be provided with powder box.Powder box can be used for replacing print cartridge, plays the effect of line equally.

The utility model is compared with prior art, and novel structure is easy to use, print cartridge is a hermetically-sealed construction, and the prepared Chinese ink in the print cartridge is not easy to volatilization and inclines to, and also need not push down sponge with finger, and after the prepared Chinese ink in the print cartridge used up, it was very convenient to change China ink, after having rule, the automatic rollback of backguy adopts the easier datum line that goes of needle body fixture, in addition, the utility model manufacturing is simple, and cost is low, practical, be worthy of promotion and application.
