Detailed Description

The following description is of the preferred embodiments of the utility model and is not intended to limit the scope of the utility model.

As shown in fig. 1-6, an adjustable height-limiting rod device for municipal roads comprises a slotted upright column unit 1, an internal thread support plate unit 2 arranged in the slotted upright column unit 1, a transverse baffle rod unit 3 sleeved on the internal thread support plate unit 2, a winding rope body unit 4 arranged in the slotted upright column unit 1 and used for lifting the transverse baffle rod unit 3 upwards, and a bending column unit 5 arranged on the winding rope body unit 4 and clamped with the internal thread support plate unit 2 and used for rotationally adjusting the height of the internal thread support plate unit 2.

In this embodiment, the general usage method and advantages of the adjustable height-limiting rod device are as follows.

In the first, initial stable state, the internal thread support plate units 2 have a fixed height, the transverse bar units 3 are supported on the two internal thread support plate units 2 at two sides, and are not easy to fall, for example, the limited height of the transverse bar units 3 is 1.9m.

Secondly, when the fire truck needs to pass temporarily, the winding rope body unit 4 is pulled down and held, the transverse baffle rod unit 3 can be lifted temporarily, for example, the height is raised to 2.2m, the general fire truck can pass through, after the fire truck passes through, the winding rope body unit 4 is loosened, and the transverse baffle rod unit 3 can be put back to the height limiting position of 1.9m.

Thirdly, when the road height limiting factor is changed, for example, the height limiting value needs to be adjusted to 1.8m for a long time, at this time, the winding rope body unit 4 is pulled down and held by one hand, the transverse baffle rod unit 3 is lifted away from the internal thread support plate unit 2, the internal thread support plate unit 2 can be rotated and adjusted downwards by rotating the bending cylinder unit 5 by the other hand, the height limiting position of 1.8m is reached, and finally the winding rope body unit 4 is released, and the adjustable height limiting rod device is a new height limiting value of 1.8 m.

In addition, the following points require additional attention.

1. The single bending range of the bending cylinder unit 5 is limited, so that the angle for actually driving the rotation adjustment of the internal thread support plate unit 2 is limited, and therefore, the bending cylinder unit 5 needs multiple bending reset operations to greatly lift and adjust the internal thread support plate unit 2, namely, the final limited height.

2. The vertical lengths of the internal thread support plate unit 2 and the curved column unit 5 are larger, the former ensures that sufficient lifting adjustment space is provided for the transverse gear lever unit 3, and the latter ensures that the internal thread support plate unit 2 is always clamped by the internal thread support plate unit itself in the adjustment operation, so that the internal thread support plate unit 2 can be rotationally adjusted all the time.

The slotted upright column unit 1 comprises a vertical column body 101, a baffle rod groove 102 which is downwards formed from the upper end surface of the vertical column body 101, and a side rope body groove 103 which is downwards formed from the inner bottom surface of the baffle rod groove 102.

In this embodiment, the transverse cross-section of the vertical column 101 may be circular or rectangular, the two vertical columns 101 and the transverse bar unit 3 form an inverted U-shaped structure, that is, the main body of the height-limiting bar device, and the side rope groove 103 is located at the outer side of the inverted U-shaped structure.

The internal thread support plate unit 2 comprises a thread column 201 arranged on the inner bottom surface of the stop rod groove 102, an internal thread ring 202 arranged on the thread column 201, and a vertical slot 203 arranged on the outer ring surface of the internal thread ring 202 and used for clamping the bending column unit 5.

In this embodiment, the internal thread ring 202 is a circular ring, and the upper surface is bonded with an antislip piece, so that the lateral stop lever unit 3 is not easy to slide left and right accidentally, and the vertical length of the thread column 201 is the entire lifting adjustment range of the lateral stop lever unit 3.

Finally, the vertical slot 203 is a force application portion of the internal threaded ring 202 that is rotationally adjusted, the curved cylinder unit 5 is clamped into a certain vertical slot 203, and then is transversely bent to a certain extent, so that the internal threaded ring 202 can be rotated by a small margin, and the lifting adjustment operation of the transverse gear lever unit 3 can be completed through multiple times of bending.

The lateral lever unit 3 includes a lateral plate 301 provided on the internally threaded ring 202, and a mounting opening 302 provided on the lateral plate 301 and adapted to pass through the threaded post 201. The mounting opening 302 is rectangular, and the long side direction of the rectangle is the length direction of the transverse plate 301.

In this embodiment, the shape of the mounting opening 302 is rectangular, the long side of the rectangle is 5-8 times the diameter of the threaded column 201, and the wide side of the rectangle is 1.2-1.5 times the diameter of the threaded column 201, so that the internal threaded support plate unit 2 will not be pulled once the transverse plate 301 is slightly deformed by impact, and therefore the transverse plate 301 can be replaced independently, thereby greatly saving the use cost of the height limiting rod device.

The winding rope unit 4 includes an upper winding rod 401 provided in the stopper rod groove 102 and higher than the lateral plate 301, a lower fixing rod 402 provided in the side rope groove 103, and a lifting rope 403 wound around the upper winding rod 401 and having one end connected to the lateral plate 301 and the other end bound to the lower fixing rod 402.

In this embodiment, the pulling rope 403 is only pulled up when the horizontal plate 301 needs to be lifted up and down, in other words, the pulling rope 403 is in a free falling state for a long period of time, that is, is hung on the upper winding rod 401, and the lower fixing rod 402 is used to ensure that the lower end of the pulling rope 403 does not randomly shake.

In addition, the main function of the pulling rope body 403 is: when the internally threaded ring 202 needs to be rotationally adjusted, the transverse plate 301 is pulled up first, so that the weight of the transverse plate 301 does not press against the internally threaded ring 202, otherwise the rotation of the internally threaded ring 202 needs to be completed with a relatively large weight against the transverse plate 301, which is laborious.

Finally, after the internal thread ring 202 is adjusted up or down to a desired height, the lifting rope 403 is slowly loosened again, and the transverse plate 301 is smoothly placed on the internal thread ring 202, so that the transverse plate 301 needs to be lifted up and then lowered down no matter how up or down is required.

The winding rope unit 4 further includes a pulling rod body 404 provided on the pulling rope body 403.

In this embodiment, the rod 404 for pulling has the following functions and advantages.

First, the pulling-down force-applying part is used for pulling down and keeping the pulling-up rope body 403 in a downward and stretching state, so that the downward pulling action of an operator is more comfortable, and a proper holding soft sleeve or a handle can be arranged in the lower area of the pulling-up rod body 404.

Secondly, the mounting position of the curved column unit 5 ensures that the curved column unit 5 cannot fall off, can be curved, and can be reset again after being curved, and the final purpose is of course to rotationally adjust the internally threaded ring 202.

Thirdly, a counterweight is added to the lifting rope body 403, so that the lifting rope body 403 cannot be greatly blown up and swung by wind even in a non-straightened state.

In addition, the vertical length of the lifting rod 404 is also required to be relatively large, so that an operator can stand on the ground and lift the hand to pull down the lifting rod 404.

The curved column unit 5 includes a rotation tube body 501 fitted over the pulling rod body 404, a radial column 502 provided on an outer circumferential surface of the rotation tube body 501, and a rotation grip column 503 provided on the radial column 502 and adapted to be engaged with the vertical slot 203.

In the present embodiment, the general usage and advantages of the curved column unit 5 are as follows.

First, the curved column unit 5 will swing slightly along with the lifting rope 403 at a high probability at the beginning, and when the horizontal plate 301 needs to be lifted and adjusted, the lifting rod 404 is held and pulled down, that is, the vertical position is not moved, and then the lifting rod 404 is readjusted back and forth, so as to clamp the rotating holding column 503 into one of the vertical slots 203.

The second rod body 404 for pulling is always fixed, then the rotating holding post 503 is bent, that is, the internal thread ring 202 is rotated by a small margin, and then the bending action is reset, that is, the rotating holding post 503 is clamped into the next vertical slot 203, and then the bending is repeated for a plurality of times, so that the internal thread ring 202 can be rotated smoothly.

Third, the radial posts 502 function to ensure that the rotating grip posts 503 are indirectly mounted on the lifting rod 404, and that the rotating grip posts 503 do not fall off during bending.

The bent cylinder unit 5 further includes a return torsion spring 504 provided between the pulling rod body 404 and the rotation pipe body 501.

In this embodiment, two ends of the return torsion spring 504 are inserted into the rod 404 for pulling and the other end is inserted into the inner ring surface of the pipe 501 for rotation, which are also conventional common mounting methods. Then, the return torsion spring 504 acts to make the bending return action of the rotating grip post 503 more labor-saving and orderly.

The radial columns 502 are elastic columns, and are engaged with different vertical slots 203 in a switching manner by means of radial inward deformation or vertical downward deformation.

In this embodiment, if the track of the bending return action of the rotating grip 503 is "original return", the female threaded ring 202 cannot be rotated all the time, so that the bending return action of the rotating grip 503 must be separated from the vertical slot 203, and therefore the radial column 502 is made of a common rubber elastic material, so that when the rotating grip 503 is bent to be separated from the vertical slot 203, the rotating grip 503 can be retracted radially inwards, or the radial column 502 can be tilted upwards and downwards, and the rotating grip 503 can be taken out from the vertical slot 203, and then be reset to be aligned with the vertical slot 203 of the rotating tube 501, that is, the force application position of the next bending action.

Therefore, the rotation holding leg 503 is not "returned to the original path" when being bent to be separated from the previous vertical groove 203, and is a necessary condition that a plurality of bending operations can be superimposed and converted into a relatively large rotation operation of the female screw ring 202.

For example, the vertical slots 203 are uniformly spaced 30 times, the rotating holding post 503 is completely bent 1 time, and the rotating holding post 503 can be pushed to rotate 3 times by the amplitude of the vertical slots 203, and if the internal thread ring 202 needs to rotate 1 turn, the rotating holding post 503 needs to be bent and reset 10 times.

Although the operation times are more, the operator can directly operate the internal thread ring 202 and indirectly operate the transverse plate 301 without any ascending equipment, which is the most basic advantage of the adjustable height-limiting rod device in the embodiment.

The embodiments of the present utility model have been described in detail with reference to the drawings, but the present utility model is not limited to the above embodiments, and various modifications may be made within the knowledge of those skilled in the art without departing from the spirit of the present utility model. These are all non-inventive modifications which are intended to be protected by the patent laws within the scope of the appended claims.
