Motor etc. is used as driving source, configures relative complex transmission mechanism and converts linear motion for rotary motion, stretches to realize
Contracting function or linear reciprocating motion function, due to complicated transmission mechanism components itself are numerous and components between connect and close
System is complicated, is easy to appear failure in the process of running, and reliability is lower, meanwhile, complicated transmission mechanism leads to telescopic device
Overall volume is excessive and loosely organized, and application is by great limitation.
Utility model content
For the problems of above prior art, the purpose of the utility model is to provide a kind of telescopic device, structures
Advantages of simple, compact and small in size, high reliablity.
To achieve the goals above, the technical solution of the utility model is:
A kind of telescopic device comprising have: driving mechanism；Reciprocating screw rod, the output axis connection with the driving mechanism；
Pilot sleeve is set on the reciprocating screw rod and connect with the driving mechanism；It offers on the pilot sleeve along it
The guiding strip-shaped hole that length direction extends；Quill is set on the pilot sleeve；Guide runner, one end setting
Between the screw thread of the reciprocating screw rod, the other end is threaded through in the guiding strip-shaped hole and connect with the quill.
The driving mechanism drives the reciprocating screw rod rotation, and the guide runner is between the screw thread of the reciprocating screw rod
Sliding, due to one end of the guide runner be threaded through in the guiding strip-shaped hole of the pilot sleeve and with the movable sleeve
Cylinder connection, the guide runner does reciprocating linear motion along the guiding strip-shaped hole, to drive the quill in institute
It states and makees stretching motion on pilot sleeve.The telescopic device is simple and compact for structure, is not susceptible to failure, and own vol is small.
As a kind of specific embodiment, chassis fixing piece is connected in the driving mechanism；The pilot sleeve and institute
State the connection of chassis fixing piece.The chassis fixing piece provides the fixed bit of the pilot sleeve.
Further, card slot is offered on the chassis fixing piece；The pilot sleeve includes to cooperate with the card slot
The buckle of connection.The card slot and the buckle are equipped with, so that the pilot sleeve is on the chassis fixing piece
It is more convenient to position, and the connection of the chassis fixing piece and the pilot sleeve is also more firm.
As a kind of specific embodiment, window is offered on the quill；The telescopic device further includes being used for
The guide-localization block being sealed on the window；The guide runner is connect with the guide-localization block.Such structure makes institute
Stating guide-localization block and the quill can dismount, so that the connection of the guide runner and the quill is more
It is easy to add, meanwhile, the guide-localization block is easily damaged due to bearing the external force of the guide runner, and such structure can pass through
Replace the guide-localization block quickly to carry out parts damages repair.
As a kind of specific embodiment, the driving mechanism includes motor and the gearbox that connect with the motor.
The gearbox can adjust the revolving speed of the motor, and thus controlling the stretching frequency of the quill.
In order to better understand and implement, according to the present invention will be described in detail below with reference to the accompanying drawings.

Specific embodiment
Please refer to Fig. 1-4, a kind of telescopic device comprising have: driving mechanism, driving mechanism include motor 1 and configuration
Gearbox 2 on motor 1；Reciprocating screw rod 8, the output axis connection with driving mechanism；Pilot sleeve 9 is set in reciprocal
It is connect on screw rod 8 and with driving mechanism；The guiding strip-shaped hole 910 extended along its length is offered on pilot sleeve 9；Activity
Sleeve 10 is set on pilot sleeve 9；Guide runner 7, one end are arranged between the screw thread of reciprocating screw rod 8, and the other end is worn
It is located in guiding strip-shaped hole 910 and is connect with quill 10.
Wherein, chassis fixing piece 4 is fixedly connected with by the first screw 3 on gearbox 2, offers card on chassis fixing piece 4
Slot 410, pilot sleeve 9 then include the buckle 920 matched with card slot 410, and pilot sleeve 9 is fixed on bottom by third screw 11
On disk fixing piece 4.
Driving mechanism drives reciprocating screw rod 8 to rotate, and guide runner 7 slides between the screw thread of reciprocating screw rod 8, due to guiding
One end of sliding block 7 is threaded through in the guiding strip-shaped hole 910 of pilot sleeve 9 and connect with quill 10, and guide runner 7 is along leading
It does reciprocating linear motion to strip-shaped hole 910, so that quill 10 be driven to make stretching motion on pilot sleeve 9.
When being sleeved on pilot sleeve 9 in view of quill 10, it is difficult to guide runner 7 is connect with quill 10,
Preferably, that a part connecting on quill 10 with guide runner 7 can cut, and form a guide-localization, and
A window 1010 is then opened up out on quill 10, guide-localization block 6 can be dismounted quickly on window 1010, be realized
The connection or disassembly of quill 10 and guide runner 7.Certainly, as shown in Figure 1, window 1010 can be designed to along quill
The notch of 10 edges cutting, guide-localization block 6 can be fixed on window 1010 by the second screw 5.
Therefore the thread that reciprocating screw rod 8 has twice opposite helical and intersects, the migration between the threads of guide runner 7 are
Move smooth of guide runner 7 and facilitate guide runner 7 and guiding strip-shaped hole 910 and cooperation, it is preferable that guide runner 7
It is designed as T shape, in guiding strip-shaped hole 910, the spiral shell of reciprocating screw rod 8 is then arranged in horizontal segment for the vertical end setting of guide runner 7
Between line.
