Abstract
The invention relates to a pin extractor, which comprises an extracting tube. The pin extractor is characterized in that: an extracting bolt is inserted into the middle of the extracting tube; the lower inner wall of the extracting tube is provided with a baffle ring which is matched with a screw cap of the extracting bolt; the lower part of the extracting bolt is provided with a screw sleeve; a extracting screw is arranged on a through hole of the lower side of the screw sleeve; the lower port of the screw sleeve is provided with an inner edge for blocking the extracting screw; and external threads which are in matched connection with internal threads of a mold pin bush are arranged on the surface of the extracting screw. The pin extractor has the advantages of simple structure and reasonable design, and can extract an internal thread pin in a pin hole in a labor-saving mode.
Description
Technical field
The present invention relates to a kind of pin extractor, particularly a kind of pin extractor of internal thread pin.
Background technology
The internal thread pin enters pin-and-hole by hitting power in use and cooperates with it, does not then have a kind of special instrument will sell in pin-and-hole in the needs dismounting and takes out easily.
Summary of the invention
The object of the present invention is to provide a kind of mould pin extractor, this product structure is simple, and is reasonable in design, can the internal thread pin in the pin-and-hole be taken out convenient and strength-savingly.
Technical program of the present invention lies in: a kind of mould pin extractor, comprise and lift body, it is characterized in that: the described body middle part of lifting is plugged with one and lifts bolt, the described body lower inner wall that lifts is provided with the baffle ring that matches with the nut that lifts bolt, the described bolt bottom that lifts is provided with swivel nut, side port is provided with and lifts screw under the described swivel nut, the lower port of described swivel nut is provided with blocks the inner edge that lifts screw, and the described screw surface that lifts is provided with the external screw thread that is connected with the screw-internal thread fit of internal thread pin.
The described nut bottom surface that lifts bolt is provided with the regular polygon deep gouge, in order to cooperating with throw.
The invention has the advantages that: the present invention is simple in structure, and is easy to use, can the internal thread pin be extracted from pin-and-hole convenient and strength-savingly, internal thread pin for the different-diameter of choosing, only need to change the screw that lifts that adapts with it and get final product, easy to use, have higher utility and promotional value.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a user mode schematic diagram of the present invention.
The specific embodiment
A kind of mould pin extractor, comprise and lift body 1, it is characterized in that: the described body middle part of lifting is plugged with one and lifts bolt 2, the described body lower inner wall that lifts is provided with the baffle ring 4 that matches with the nut 3 that lifts bolt, the described bolt bottom that lifts is provided with swivel nut 5, side port is provided with and lifts screw 6 under the described swivel nut, and the lower port of described swivel nut is provided with blocks the inner edge 7 that lifts screw, and the described screw surface that lifts is provided with the external screw thread that is connected with the screw-internal thread fit of internal thread pin 8.
The described nut bottom surface that lifts bolt is provided with the regular polygon deep gouge, in order to cooperating with throw.
Use of the present invention is as follows: the swivel nut of rotary pulling bolt bottom before using, and swivel nut moves upward, and the lower surface that lifts bolt is closely contacted with the nut that lifts screw, is lifting under the restriction of bolt, lifts screw and is fixed; To lift the screw-internal thread fit of the external screw thread and the internal thread pin of screw, and screw in certain degree of depth, hand-held lift body and upwards lift, the internal thread pin can be extracted from pin-and-hole.Only need change the screw that lifts that adapts with it for the internal thread pin of different size gets final product.
The above only is preferred embodiment of the present invention, and all equalizations of being done according to the present patent application claim change and modify, and all should belong to covering scope of the present invention.
