Description
Technical field
The utility model is related to a kind of automobile tail gate push rod transmission mechanism, specifically a kind of interior guiding screw rod transmission knot
Structure belongs to automobile tail gate pusher structure technical field.
Background technology
With economic development, people's living standards continue to improve, people are to the speed of service of vehicle and its comfortable
The requirement of property is also constantly improving.Existing part push rod can not use caused by the limitation in part three-box car tail-gate region
In the part vehicle, it is therefore desirable to design it is a kind of can be to the tail-gate push rod that three-box car uses.In the prior art, tail-gate push rod
Lead screw transmission mechanism transmission is all generally realized using guide frame outside metal material, use cost is high, operational process
In easily generate mechanicalness noise, and need to separately buy riveting equipment, be not easy to be widely used to promote.Therefore it needs for current institute face
Research and develop a set of economical and practical interior guiding screw rod transmission structure the problem of facing.
Invention content
In place of the purpose of this utility model is to overcome above-mentioned deficiency, screw rod transmission structure is oriented in one kind so as to provide,
Cost can be reduced, it is easy to assembly, and screw can be effectively reduced in the process of running because of the mechanicalness noise that friction generates, increase production
Product service life, it is ensured that push rod is safely and smoothly run, and passenger is made to feel more comfortable.
According to technical solution provided by the utility model, a kind of interior screw rod transmission structure that is oriented to includes interior bar, screw, screw
Nut pipe and guide pipe, it is characterized in that：Connection wire rod in interior bar, screw and interior bar are integrally formed using Shooting Technique；Before screw
End is stretched into feed screw nut's pipe and is connected through a screw thread with feed screw nut's pipe, and interior rod rear end stretches out feed screw nut's pipe；Feed screw nut
Pipe is located in guide pipe, and guide pipe is stretched out in feed screw nut's pipe front end；Guide groove, silk are equipped on guide pipe madial wall along its length
Stem nut tube outer surface is equipped with guide runner, and the guide runner of feed screw nut's pipe is slidably connected in the guide groove of guide pipe.
Further, interior bar is made of metal material.
Further, screw is made of plastic material.
Further, screw front end is equipped with limited block, and the diameter of limited block is more than the diameter of screw ontology.
Further, limiting stand is equipped on the inside of guide pipe, limiting stand can stop that feed screw nut manages end motion backward.
Further, feed screw nut's pipe is made of plastic material.
Further, guide pipe makes for metal material.
Compared with the prior art the utility model has the following advantages：
The utility model is simple in structure, compact, reasonable, can reduce cost, easy to assembly, and can effectively reduce screw and exist
Because of the mechanicalness noise that friction generates in operational process, increase product service life, it is ensured that push rod is safely and smoothly run, and makes to multiply
Visitor feels more comfortable.
Description of the drawings
Fig. 1 is the utility model half sectional view.
Reference sign：1- interior bars, 2- screws, 3- feed screw nut's pipe, 4- guide pipes, 5- limited blocks, 6- limiting stands.
Specific embodiment
The utility model will be further described with reference to the embodiment in attached drawing below：
As shown in Figure 1, the utility model mainly includes interior bar 1, screw 2, feed screw nut's pipe 3 and guide pipe 4.
Connection wire rod 2 in interior bar 1, interior bar 1 are made of metal material, and screw 2 is made of plastic material, 2 He of screw
Interior bar 1 is integrally formed using Shooting Technique.
2 front end of screw is equipped with limited block 5, and the diameter of limited block 5 is more than the diameter of 2 ontology of screw.Limited block 5 ensures
Feed screw nut's pipe 3 will not come off when moving from screw 2.
2 front end of screw is stretched into feed screw nut's pipe 3 and is connected through a screw thread with feed screw nut's pipe 3, and silk is stretched out in 1 rear end of interior bar
Interior bar 1 is attached by 3 personnel easy to operation of stem nut pipe with driving.Feed screw nut's pipe 3 is made of plastic material.
Feed screw nut's pipe 3 is located in guide pipe 4, and guide pipe 4 is stretched out in 3 front end of feed screw nut's pipe.4 madial wall upper edge of guide pipe
Length direction is equipped with guide groove, and 3 outer surface of feed screw nut's pipe is equipped with guide runner, and the guide runner of feed screw nut's pipe 3 slides
It is connected in the guide groove of guide pipe 4.The guide pipe 4 makes for metal material.
4 inside of guide pipe is equipped with limiting stand 6, and limiting stand 6 can stop the end motion backward of feed screw nut's pipe 3.
The operation principle of the utility model is：When screw positive and negative rotation moves, by the spiral lamination on screw by screw
Positive and negative rotation movement be converted to feed screw nut's pipe Linear scaling movement, in order to avoid feed screw nut's pipe linear motion when revolve
Turn, increase the guide pipe for guiding, feed screw nut's pipe is avoided to rotate by the guide frame of guide pipe.Work as feed screw nut
It when pipe reaches maximum rating, is limited by the limited block of screw one end, feed screw nut's pipe is avoided to come off from screw.When
When feed screw nut's pipe is retracted to minimum state, limited by the limiting stand in the end thereof contacts to guide pipe of feed screw nut's pipe
Position.When screw rod transmission structure is run, because its screw and feed screw nut's pipe are plastic material, effectively prevent what friction generated
Mechanicalness noise.
The utility model is simple in structure, compact, reasonable, can reduce cost, easy to assembly, and can effectively reduce screw and exist
Because of the mechanicalness noise that friction generates in operational process, increase product service life, it is ensured that push rod is safely and smoothly run, and makes to multiply
Visitor feels more comfortable.
