Abstract
The invention relates to a bidirectional locking screw which comprises a screw head. An upper screw rod is connected to the upper surface of the screw head, a lower screw rod is connected to the lower surface of the screw head, the upper screw rod and the lower screw rod are full-threaded screw rods, threads on an upper threaded rod are clockwise threads, threads on the lower screw on a lower threaded rod are anticlockwise threads, a threaded head is an outer hexagonal threaded head, a locking rotary hole is formed in the outer surface of the outer hexagonal threaded head, and the screw head, the upper threaded rod and the lower threaded rod form an integral structure. By means of the design, double ends of the bidirectional locking screw can be screwed on two parts to enable the two parts to be combined.
Description
Technical field
The present invention relates to the field of component of machine, especially a kind of reversible lock compact form screw.
Background technique
Screw utilizes the inclined-plane circular rotating of object and the physics of frictional force and mathematical principle, the by easy stages instrument of fastening implements parts.Screw is the general saying of fastening piece, daily pet phrase.Screw is industrial necessity indispensable in daily life: the minimum screw used as photographic camera, glasses, clock and watch, electronics etc.; The general screw of TV, electric product, musical instrument, furniture etc.; Large-scale screw, nut is then used as engineering, building, bridge; Traffic tool, aircraft, electric car, automobile etc. then sized by screw using.Screw industrially bears vital task, as long as the earth also exists industry, then the function of screw is forever important.
The screw of current use is all only possess a lead screw, can only be screwed on a part, due to for some special dimensions, needs to use needed for two lead screw can realize.
Summary of the invention
The technical problem to be solved in the present invention is: in order to overcome above-mentioned middle Problems existing, provides a kind of reversible lock compact form screw, its project organization rationally, can special dimension be applicable to.
The technical solution adopted for the present invention to solve the technical problems is: a kind of reversible lock compact form screw, comprise screw terminal, described screw terminal upper surface is connected with bar of tightening up a screw, screw terminal lower surface is connected with lower lead screw, described bar and the lower lead screw of tightening up a screw is full flight screw, screw thread on upper threaded stem is clockwise thread, screw thread on lower threaded stem is anti-clockwise thread, described thread head is outer-hexagonal thread head, outer-hexagonal thread head outer surface offers locking rotating hole, and described screw terminal, tighten up a screw bar and lower lead screw are structure as a whole.
The invention has the beneficial effects as follows: described a kind of reversible lock compact form screw, adopt the screw of this kind of design, double end can be realized and be screwed on two parts, two parts are combined.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the overall structure schematic diagram of a kind of reversible lock compact form screw of the present invention.
Accompanying drawing acceptance of the bid note is described below: 1, screw terminal, and 2, bar of tightening up a screw, 3, lower lead screw, 4, clockwise thread, 5, anti-clockwise thread, 6, locking rotating hole.
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
A kind of reversible lock compact form screw as shown in Figure 1, comprise screw terminal 1, screw terminal 1 upper surface is connected with bar 2 of tightening up a screw, screw terminal 1 lower surface is connected with lower lead screw 3, and tighten up a screw bar 2 and lower lead screw 3 are full flight screw, and the screw thread on upper threaded stem 2 is clockwise thread 4, screw thread on lower threaded stem 3 is anti-clockwise thread 5, thread head 1 is outer-hexagonal thread head, outer-hexagonal thread head outer surface offers locking rotating hole 6, and screw terminal 1, tighten up a screw bar 2 and lower lead screw 3 are structure as a whole.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to right.
