Scheme and attached drawing.
Fig. 1 is the schematic diagram of the embodiment of the present invention one；
Fig. 2 is the schematic diagram of the embodiment of the present invention two.
Specific embodiment
It is carried out below with reference to technical effect of the embodiment and attached drawing to design of the invention, specific structure and generation clear
Chu is fully described by, to be completely understood by the purpose of the present invention, feature and effect.Obviously, described embodiment is this hair
Bright a part of the embodiment, rather than whole embodiments, based on the embodiment of the present invention, those skilled in the art are not being paid
Other embodiments obtained, belong to the scope of protection of the invention under the premise of creative work.In addition, be previously mentioned in text
All connection relationships not singly refer to that component directly connects, and referring to can be according to specific implementation situation, by adding or reducing connection
Auxiliary, to form more preferably connection structure.Each technical characteristic in the invention, under the premise of not conflicting conflict
It can be with combination of interactions.
It referring to Fig.1, is the embodiment of the present invention one, specifically:
A kind of push rod, including the first screw component, the second screw component, first gear 16, second gear 161；
First screw component includes the first screw rod 13 and covers the first screw rod bushing 14 outside first screw rod 13, institute
The rear end for stating the first screw rod 13 is set in first screw rod bushing 14, and the front end of first screw rod 13 is rotatably connected the
A connection piece 19, first screw rod 13 is coaxial with first connector 19, and first connector 19 is set to described first
14 front of screw rod bushing, first screw rod 13 are threadedly coupled with first screw rod bushing 14, the rear end of first screw rod bushing 14
It is connected with the first secondary connector 17；
Second screw component includes the second screw rod 131 and covers the second screw rod bushing outside second screw rod 131
141, the rear end of second screw rod 131 is set in second screw rod bushing 141, and the front end of second screw rod 131 is rotatable
Ground is connected with the second connector 191, and second connector 191 is set to 141 front of the second screw rod bushing, second screw rod
131 are threadedly coupled with second screw rod bushing 141, and the rear end of second screw rod bushing 141 is connected with the second secondary connector 171,
The screw thread on 131 surface of the second screw rod and the thread pitch on 13 surface of the first screw rod are identical and oppositely oriented；
16 sets of the first gear and with first screw rod 13 affixed, the first gears outer in first screw rod 13
16 are set between first connector 19 and first screw rod bushing 14；161 sets of the second gear in second screw rod
131 is outer and affixed with second screw rod 131, and the second gear 161 is set to second connector 191 and described second
Between rod set 141；The first gear 16 is engaged with the second gear 161.
The working principle of the invention is: first gear 16, the second gear 161 of engagement drive the first screw rod 13, second
131 synchronous backward of bar rotation, since the hand of spiral on 131 surface of the second screw rod is identical as the thread pitch on 13 surface of the first screw rod
Its is contrary, so, when the first screw rod 13, the rotation of the second screw rod 131, the first screw rod bushing 14, the second screw rod bushing 141 are synchronous
Ground moves forwards or backwards, so rotation is become linear motion by the push rod.Since the front end of first screw rod 13 can revolve
It is connected with the first connector 19 with turning, so be unaffected when the rotation of the first screw rod 13 with extraneous connection,
In it is rotatable connection can be the first screw rod 13 front end be arranged cavity, the cavity is inserted into the tail portion of the first connector 19
In, cavity can also be set in the tail portion of the first connector 19 in turn, the front end of the first screw rod 13 is inserted into the cavity, etc.
Mode.
Since the first screw rod bushing 14, the second screw rod bushing 141 are to move synchronously, and the integral strength of screw rod bushing improves, so should
Push rod intensity is higher.It is, of course, also possible to add screw rod and screw rod bushing on the basis of the present embodiment, protection of the invention is also belonged to
Range.
It further, further include motor 12, master gear 15, the center of the output end of the motor 12 and the master gear 15
Affixed, the master gear 15 is engaged with the second gear 161.Above structure drives the push rod with motor 12, is a kind of electronic
The implementation of push rod.
It further, further include shell, the shell includes main casing 11, the tubular shell set on 11 rear end of main casing
Body 18, the main casing 11 is interior to be equipped with main installation cavity, is equipped with tubular cavity, the main installation cavity and institute in the tubular shell 18
State tubulose installation cavity connection, the motor 12, master gear 15, first gear 16, second gear 161, the first screw rod 13 front end,
The front end of second screw rod 131 is set in main installation cavity, the front end of the first screw rod bushing 14, the second screw rod bushing 141 front end be all provided with
In in tubular cavity, glade plane space is equipped between first screw rod bushing 14, the second screw rod bushing 141 and the tubular shell 18,
First connector 19, the second connector 191 are set in front of the shell, the described first secondary connection of secondary connector 17, second
Part 171 is set to the shell rear.Above-mentioned shell makes the push rod shape neat and artistic, can be used as a global facility fortune
Defeated, installation, disassembly.
Further, the shell is equipped with radiating opening.In use, there are many friction for above-mentioned push rod, heat compared with
More, setting radiating opening is conducive to its heat dissipation.
It is the embodiment of the present invention two, the difference with embodiment one is referring to Fig. 2:
Described first secondary connector 17 and the described second secondary connector 171 are affixed.When push rod use so can be improved
Stability.Due to being equipped with glade plane space between the first screw rod bushing 14, the second screw rod bushing 141 and the shell, so first
Opposite movement may be generated between rod set 14, the second screw rod bushing 141, and the described first secondary connector 17 and described second
Secondary connector 171 is affixed can be to avoid this relative movement, to improve stability.
Further, the described first secondary connector 17 is integrally formed with the described second secondary connector 171.After integrated molding
The first secondary connector 17 and the second secondary connector 171 intensity height, also, the integrally formed part can be used as an entirety
It is connect with the external world, in this way, only needing one with extraneous tie point, can simplify connection structure.
Further, first screw rod bushing 14 and second screw rod bushing 141 are affixed.
Further, first screw rod bushing 14 is integrally formed with second screw rod bushing 141.By the first screw rod bushing 14 with
Second screw rod bushing 141 is affixed or integrally formed act on mainly can be improved intensity.
Further, first connector 19 and second connector 191 are affixed.
Further, first connector 19 is integrally formed with second connector 191.By the first connector 19 with
Second connector 191 it is affixed or it is integrally formed effect equally in addition to improve intensity, there are also simplify connection structure effect.
Better embodiment of the invention is illustrated above, but the invention is not limited to the implementation
Example, those skilled in the art can also make various equivalent modifications on the premise of without prejudice to spirit of the invention or replace
