In one embodiment, the device further comprises a second spring, and two second springs are connected between the bottom of the pressure plate and the top of the first cross rod.
When the worker needs to install the fence, the worker can move the fence to an installation place firstly, then the first inserted rod is inserted on the ground and fixed, when the height of the fence needs to be increased, the worker can pull the first cross rod upwards, the first cross rod moves upwards to drive the second inserted rod to move upwards, meanwhile, the first cross rod moves upwards to drive the connecting rod to move upwards and the upper part of the connecting rod rotates leftwards, the lower part of the connecting rod rotates rightwards, so that an acute angle formed by the connecting rod and the connecting rod is gradually increased, the height of the fence is increased, the connecting rod moves upwards through the guide sleeve belt-shaped block and the connecting rod, meanwhile, the lower part of the connecting rod rotates rightwards to drive the guide sleeve to slide rightwards, the body-shaped block moves rightwards, the body-shaped block is not matched with the first latch any more, when the connecting rod rotates to a, under the action of gravity, the second inserted bar and the first cross bar move downwards, and simultaneously the body block can move downwards until being matched with the corresponding first latch, so as to achieve the effect of fixing the guide sleeve, thereby fixing the position of the connecting rod, when the height of the fence needs to be reduced and reset, a worker can slightly pull the first cross rod upwards to drive the body-shaped blocks to move upwards and not to be matched with the first latch any more, then, the lower part of the connecting rod is slid leftwards by hand to rotate leftwards, the upper part of the connecting rod rotates rightwards along with the lower part of the connecting rod, so that the acute angle formed by the connecting rod and the connecting rod is gradually reduced, the height of the fence is reduced, when the connecting rod rotates to the minimum angle, the first cross rod is released, under the action of gravity, the first cross rod moves downwards to reset, the body-shaped block moves downwards along with the first cross rod to be matched with the corresponding first latch, the position of the connecting rod is fixed, so that the height of the fence can be conveniently adjusted by workers according to different requirements.
In the in-process of adjusting the rail height, the connecting rod rebound drives second horizontal pole rebound through the sliding shaft, the kelly plays the guide effect to the second horizontal pole, adjust high back, the staff loosens first horizontal pole, the connecting rod drives second horizontal pole rebound through the sliding shaft, when bodily form piece rebound to with corresponding first latch cooperation, the second horizontal pole stops the rebound, the second horizontal pole can prevent that people or animal from passing from the centre of rail, avoid being blocked in the middle of the rail.
When the worker needs to adjust the height of the fence, the worker can press the plate downwards, the pressing plate moves downwards to drive the concave ball to move downwards through the guide rod and extrude the stay wire, the first pulley, the second pulley and the third pulley play a role in guiding the stay wire, the stay wire is tightened to drive the clamping blocks on the left side and the right side to move outwards, so that the clamping block is not matched with the second clamping tooth any more, the first spring is compressed along with the second clamping tooth, at the moment, a worker can stop pressing the plate downwards and keep the current position of the pressing plate, then the steps are repeated to adjust the height of the fence, after the adjustment is finished, a worker can move the pressing plate upwards to reset, the pressing plate moves upwards to drive the concave ball to move upwards through the guide rod to reset, so that the concave ball does not press the pull line downwards any more, under the effect of first spring, the fixture block moves to the inboard and cooperates with the second latch, so, can prevent that passerby from pulling first horizontal pole at will and changing the rail height.
Concave ball downstream passes through the third latch downstream of both sides about the connecting plate drives, when the third latch downstream of both sides about moves and passes the card hole and block first horizontal pole bottom, the staff can loosen the clamp plate, adjust the rail height, adjust the back that finishes, the staff can move the connecting plate of both sides about the inboard earlier, make the third latch no longer block first horizontal pole, after that the rebound clamp plate resets can, so make the staff need not to push down the clamp plate when upwards pulling first horizontal pole always, and is more laborsaving, work burden has been alleviateed.
When adjusting the rail height, the staff is pressed the clamp plate downwards, and the second spring is compressed thereupon, has adjusted high back, and the staff loosens the clamp plate, and the second spring drives the clamp plate rebound thereupon and resets, so need not artifical manual rebound clamp plate, has further alleviateed staff's burden.
The beneficial effects are that: according to the invention, the height of the fence is increased by pulling the first cross rod upwards by a worker, the body-shaped blocks move upwards along with the first cross rod and are not matched with the first clamping teeth, when the height of the fence is adjusted to a proper height, the first cross rod is loosened, the body-shaped blocks move downwards to be matched with the corresponding first clamping teeth, and the position of the connecting rod is fixed, so that the height of the fence can be conveniently and easily adjusted according to requirements; by arranging the second cross bar, people or animals can be prevented from passing through the middle of the fence, and the situation that the people or animals are clamped in the middle of the fence is avoided; the pressing plate is driven to move upwards to reset by the second spring, so that a worker does not need to move the pressing plate upwards, and the pressing device is more labor-saving and convenient.
