Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
A kind of campus fence, as depicted in figs. 1 and 2, if including four vertical supporting rods 11, between each supporting rod 11
Spacing for ten centimetres, pedestrian can be prevented to be passed through between supporting rod 11.Supporting rod 11 is fixedly connected with horizontally disposed horizontal stroke
Beam 21 plays the role of reinforcement support bars 11, improves structural stability.11 upper end of supporting rod is equipped with what is be connected with its vertical sliding
Spine spearhead 12, spine spearhead 12 are equipped with sawtooth 14, can have spine spearhead 12 by sawtooth 14 and people is prevented to cross supporting rod
11 function.Supporting rod 11 is equipped with vertical sliding slot 15, and spine spearhead 12, which is fixedly connected with, abuts block 13, and abutting block 13 can be in cunning
Vertical sliding in slot 15 when abutting block 13 moves up and down, can drive spine spearhead 12 to move up and down.
Crossbeam 21 is splitted, as shown in figure 3, level slidably connects sliding bar 22 in crossbeam 21, sliding bar 22, which is fixed, to be connected
Be connected to the wedge block 23 with abutting the clamping of 13 lower end of block, when sliding bar 22 drives wedge block 23 is horizontal to be slided when, abut block 13 with
The mobile drive spine spearhead 12 of wedge block 23 moves up and down.Wedge block 23 is equipped with horizontal low degree 24, and wedge block 23 is equipped with
Horizontal and height is higher than the high plane 25 of low degree 24.When abutting block 13 with the clamping of low degree 24, block 13 and spine lance are abutted
First 12 are in extreme lower position, and spine spearhead 12 is received to inside supporting rod 11.When abutting block 13 with the clamping of high plane 25, support
It connects block 13 and is in extreme higher position with spine spearhead 12, spine spearhead 12 is stretched out out of supporting rod 11, and spine spearhead 12 stretches out support
11 top of bar can play the role of preventing people from crossing supporting rod 11.Meanwhile spine spearhead 12 is by external force when being acted on, spine spearhead 12
Along high plane 25 wedge block 23 cannot be promoted to move, so that spine spearhead 12 can be more stable is maintained at extreme higher position.
As shown in Figure 3 and Figure 4, sliding bar 22 is fixedly connected with horizontally disposed rack 26, and sliding bar 22 is equipped with gear
Structure, linkage mechanism include driving shaft 34 and the drive gear 32 engaged with rack 26, and drive gear 32 is rotatablely connected with crossbeam 21,
When drive gear 32 rotates, it can be moved with carry-over bar 26.Gear, variable-speed motor are equipped between drive gear 32 and driving shaft 34
Structure includes driving gear 35, driven shaft 31 and driven gear 33, and driving gear 35 is fixedly connected with driving shaft 34, driven shaft 31 and
Drive gear 32 is fixedly connected, and driven gear 33 is fixedly connected with driven shaft 31 and is engaged with driving gear 35.Make driving shaft 34
During rotation, driving shaft 34 drives driving gear 35 to rotate, and driving gear 35 drives the driven gear 33 engaged to rotate, driven
Gear 33 drives drive gear 32 to rotate by driven shaft 31 again, so that rack 26 and sliding bar 22 move.
33 reference diameter of driven gear is more than 32 reference diameter of drive gear so that at 32 reference circle of drive gear
Linear velocity is less than the linear velocity at 33 reference circle of driven gear.When driving gear 35 drives the rotation of driven gear 33, driving gear
Linear velocity at 35 reference circles is equal to the linear velocity at 33 reference circle of driven gear, therefore the linear velocity at 32 reference circle of drive gear
Less than the linear velocity at 35 reference circle of driving gear.So as to playing the effect of deceleration, slow down 26 translational speed of rack, meanwhile,
The torque of drive gear 32 can be improved, drive gear 32 is made to have the torque band carry-over bar 26 of bigger and sliding bar 22 to move.
As shown in Figure 4 and Figure 5, driving shaft 34 is equipped with pin hole 36, and driving shaft 34 is equipped with driving portion, and driving portion is to be arranged on pin
Drive pin 41 in hole 36, drive pin 41 are stretched out from 21 inside of crossbeam outside crossbeam 21, and bayonet 37, drive pin are equipped in pin hole 36
41 are equipped with the draw key 42 that can be clamped with bayonet 37.Drive pin 41 is rotated, the draw key 42 on drive pin 41 is made to drive driving shaft
34 rotate, and so as to fulfill by rotating drive pin 41 driving shaft 34 are driven to rotate.
Draw key 42 is slidably connected with drive pin 41, and 42 glide direction of draw key is vertical with 41 length direction of drive pin, drives
Dynamic pin 41 is equipped with the compression spring 43 that both ends are fixedly connected respectively with drive pin 41 and draw key 42, and compression spring 43 drives activity
Key 42 is clamped with bayonet 37, and draw key 42 can be made to keep the state being clamped with bayonet 37, so as to play effect easy to use.
Draw key 42 is equipped with chamfering 44, and when pulling drive pin 41 to 36 outside of pin hole, bayonet 37 can be along chamfering 44 into drive pin 41
Side promotes draw key 42, draw key 42 is made to release the state of clamping with bayonet 37, so as to which drive pin 41 is taken out of pin hole 36
It walks so that wanting the personnel of climbing fence cannot use the common instrument such as hand or spanner to rotate drive pin 41, and people is prevented so as to play
Climb the effect of fence.
Drive pin 41 is fixedly connected with handle 45, by rotating handles 45, drive pin 41 can be driven to rotate.Handle 45 is equipped with
Non-slip texture 46 plays the role of facilitating rotating handles 45.
Specific implementation process：Original state, spine spearhead 12 are located at extreme lower position, and drive pin 41 is located at outside pin hole 36.
Spine spearhead 12 is in supporting rod 11, can easily carry out the carrying or installment work of fence.
When needing to make spine spearhead 12 to stretch out supporting rod 11, drive pin 41 is inserted into pin hole 36, make draw key 42 with
Bayonet 37 is clamped.By swing handle 45 drive pin 41 is driven to rotate, drive pin 41 drives 34 turns of driving shaft by draw key 42
Dynamic, driving shaft 34 drives driving gear 35 to rotate, and driving gear 35 drives driven gear 33 to rotate, and driven gear 33 is by driven
Axis 31 drives drive gear 32 to rotate, then is moved by drive gear 32 with carry-over bar 26 and sliding bar 22.Sliding bar 22 drive with
Its wedge block 23 being fixedly connected moves, and abutting block 13 is made to be pushed up by wedge block 23, abuts the process that block 13 moves up
In, spine spearhead 12 is driven to stretch out 11 top of supporting rod, so as to by spine spearhead 11 people be prevented to cross supporting rod 11.Then
It takes drive pin 41 away, prevents other people from will rotate driving shaft 34, move down spine spearhead 12.
This specific embodiment is only explanation to the utility model, is not the limitation to the utility model, ability
Field technique personnel can as needed make the present embodiment the modification of no creative contribution after this specification is read, but
As long as it is all protected in the right of the utility model be subject to Patent Law.
