Utility model content
Technical problem to be solved in the utility model is to provide a kind of solder sucker that can temporarily hold scolding tin.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of solder sucker, comprise suction nozzle, suction tube, piston, push rod, extension spring and position limiting structure, suction nozzle is connected with suction tube head, piston and push rod are coaxially fixing, piston sliding fit is in suction tube cavity, piston and being contained on sealing ring on piston is divided into the cavity of suction tube, cavity of resorption, the cross section of sealing ring is trapezoidal and sealing ring is provided with trapezoidal circular groove away from one end of suction nozzle, position limiting structure is by limit base, the button and the stage clip that are provided with spacer pin form, limit base is fixed on the afterbody of suction tube, push rod is provided with the spacing ring coordinating with spacer pin, extension spring one end is connected with piston, the extension spring other end is connected with limit base, the tail end of described suction nozzle is provided with internal thread, described suction tube head is provided with the external screw thread mating with internal thread, the head of described suction nozzle is provided with appearance molten tin bath.
Compared with prior art, the utility model has the advantage of the syndeton that has changed suction nozzle and suction tube head, and added appearance molten tin bath at the head of suction nozzle, can temporarily hold the scolding tin siphoning away, and run up to a certain amount of after, after detachable suction nozzle and suction tube, scolding tin is concentrated and poured out, kept the clean and tidy of working environment; And the cross section of sealing ring is made as to trapezoidal and sealing ring, away from one end of suction nozzle, be provided with trapezoidal circular groove, make trapezoidal circular groove owing to being subject to the squeezing action of air-flow, opening expands, and can after using the long period, still keep sealing.
As improvement, also comprise and being located in cavity of resorption for scolding tin being imported to the gear tin ring holding in molten tin bath.The scolding tin siphoning away is better rolled in appearance molten tin bath.
As preferably, described gear tin ring comprise outside connecting ring and from lower to upper flare setting lead tin ring, connecting ring with lead the connection strap by a plurality of circle distribution between tin ring and be connected, described gear tin ring is fixing by suction nozzle head and the suction tube ring that is clamped and connected.
As preferably, described gear tin ring is made by silicon rubber.Make suction nozzle and suction tube head form sealing.
As improvement, described limit base is provided with for guiding the axially movable guide ring of push rod.Strengthen guide effect, reduce the wearing and tearing of sealing ring.
