Two sides are cased with the nut 4 that a corresponding side screw thread matches respectively, and two 4 bilateral symmetries of nut, the rotation of threaded rod 3 can
Drive two nuts 4 towards or away from movement, the bottom of 1 or so two wall surface of cabinet is respectively articulated with a connecting rod 5, under connecting rod 5
End is hinged with the wall surface of cabinet 1, and upper end is equipped with left and right directions to 1 vertical direction centerline dip of cabinet, the bottom level of cabinet 1
The first sliding rail 6, each nut 4 is respectively fixedly connected with first sliding block 7 that can be slided on the first sliding rail 6, each first
A support rod 8, the connecting rod 5 of the corresponding side in one end of support rod 8 are respectively equipped between the connecting rod 5 of the corresponding side of sliding block 7
Intermediate hinged, the first sliding block 7 of the corresponding side of the other end is hinged, and the lower end surface level of plate 2 is equipped with a left and right directions
Second sliding rail 9, the second sliding rail 9 is respectively arranged on the left side and the right side second sliding block 10, and the second sliding block 10 cannot be detached from second and slide
Rail 9,5 upper end of connecting rod that the second sliding block 10 distinguishes corresponding side is hinged, and two the second sliding blocks 10 can be towards or away from sliding, band
Dynamic plate 2 moves up and down.
In order to realize the rotation of threaded rod 3,3 middle position of threaded rod is arranged with a first bevel gear 11, and first
A second bevel gear 12 is engaged with below bevel gear 11, the center of second bevel gear 12 is equipped with a mandrel 13, mandrel 13
The one end for stretching out second bevel gear 12 passes through the bottom of cabinet 1, and is connected with a turntable 14, and the lower end surface of turntable 14 offers
One rectangle square groove 15, the interior dismountable handle 16 of installation of square groove 15, swing handle 16 drive the rotation of second bevel gear 12.
In order to realize that the second sliding block 10 can not be detached from the second sliding rail 9, second sliding rail 9 uses inverted T-shaped sliding rail, and second is sliding
The upper surface of block 10 offers an inverted T-shaped groove, slide the second sliding block 10 can on the second sliding rail 9 and without departing from second
Sliding rail 9.
It in order to realize sliding up and down for plate 2, is set between the plate 2 and cabinet 1 there are two runner 17, runner 17 and flat
Plate 2 is fixedly connected.
In order to realize cabinet 1 and there is gap on ground, set that there are two stabilizer blades 18 on the bottom surface of the cabinet 1.
The specific work process of the utility model is: when the second bevel gear 12 of this protective fence rotates clockwise, driving
First bevel gear 11 rotates clockwise, and first bevel gear 11 is sleeved on threaded rod 3, and first bevel gear 11 rotates clockwise drive
Threaded rod 3 rotates clockwise, since the thread rotary orientation of the left and right sides of threaded rod 3 is on the contrary, therefore two 4 back movements of nut,
Nut 4 is fixedly connected with the first sliding block 7, and the back movement of nut 4 drives the first sliding block 7 to slide opposite to each other on the first sliding rail 6, the
The opposite sliding of one sliding block 7 makes the support rod 8 of respective side by two component horizontally outward and straight up, horizontally outward
Component moves horizontally the connecting rod 5 of respective side and the second sliding block 10 to the direction away from vertical direction center line, straight up
Component moves the connecting rod 5 of respective side and the second sliding block 10 straight up, due to the second sliding block 10 on 2 lower end surface of plate
It is slided on two sliding rails 9, therefore mobile drive plate 2 moves the second sliding block 10 straight up straight up.
When the second bevel gear 12 of this protective fence rotates counterclockwise, first bevel gear 11 is driven to rotate counterclockwise, first
Bevel gear 11 is sleeved on threaded rod 3, and first bevel gear 11, which rotates counterclockwise, drives rotating counterclockwise for threaded rod 3, due to spiral shell
The thread rotary orientation of the left and right sides of rasp bar 3 is on the contrary, therefore two 4 relative motions of nut, nut 4 are fixedly connected with the first sliding block 7, spiral shell
The relative motion of mother 4 drives the opposite sliding on the first sliding rail 6 of the first sliding block 7, and the opposite sliding of the first sliding block 7 makes respective side
For support rod 8 by two component in horizontal direction and straight down, the component in horizontal direction makes the connecting rod 5 of respective side and second sliding
Block 10 is moved horizontally to the direction close to vertical direction center line, and component straight down slides the connecting rod 5 of respective side and second
Block 10 moves straight down, since the second sliding block 10 slides on the second sliding rail 9 on 2 lower end surface of plate, the second sliding block
10 movements straight down drive plate 2 to move straight down.
When 2 hit the ceiling of plate, the acute angle of support rod 8 and connecting rod 5 reaches threshold limit value, acute angle
Threshold limit value is not influence plate 2 to decline the support rod 8 of process and the maximum angle of connecting rod 5.Plate 2 drops to extreme lower position,
When i.e. plate 2 is fully retracted in cabinet 1, the acute angle of support rod 8 and connecting rod 5 reaches minimum limit value, and acute angle is most
Small limit value is not influence the support rod 8 of 2 uphill process of plate and the minimum angle of connecting rod 5.
This protective fence, which compares traditional protective fence, to be advantageous in that, this protective fence solves protection using traditional mechanical structure
The height-limited problem in column, and this protective fence can satisfy user in height model by manually controlling the lifting of its height
Enclose interior arbitrary height.
The utility model is novel, clever structure, practical, passes through driving towards or away from movement for two sliding blocks
Plate moves up and down, and realizes the lifting on protective fence vertical direction, does not influence to transport again while increasing protective fence height.
