Detailed Description

The drawings illustrate specific embodiments of the invention. As shown in fig. 1 to 5, the meter collecting box comprises a box body 1 and a box door 2, wherein the box door 2 is a two-leaf split door, a partition plate 3 is installed at the upper end in the box body 1, a cavity 4 is formed between the partition plate 3 and the upper end of the box body 1, a push-pull tripod 20 is installed in the cavity 4, four rollers 19 are installed on the push-pull tripod 20, the push-pull tripod 20 can be pulled out and pushed in like a drawer, but can not fall out when pulled out (like a keyboard placing plate of a computer desk), two sliding blocks can be installed on two sides of the rear end of the push-pull tripod, two sides of the cavity 4 are respectively a groove with a front end sealed, and the sliding blocks are located in the grooves.

Two reels 7 in the front and back direction are arranged at the upper end of the push-pull tripod 20, one reel 7 is provided with a crank 8, the crank 8 can be in a knob type, gears 9 are respectively arranged at the front end and the back end of the two reels 7, and the two gears 9 at the same end are meshed with each other, so that linkage is formed; the rain cover 11 is arranged above the two scroll shafts 7, the front end and the rear end of the rain cover 11 are respectively arranged on the push-pull tripod 20, meanwhile, the upper surface of the cavity 4 is provided with the rain scraping plate 12, the shapes of the rain scraping plate 12 and the rain cover 11 are the same, the cross section of the rain scraping plate can be arc-shaped or inverted V-shaped, and in the drawing process of the push-pull tripod 20, the rain scraping plate 12 scrapes rainwater or snow on the rain cover 11.

The front end and the rear end of two slopes of the push-pull tripod 20 are respectively provided with a sliding groove 13, the notches of the two sliding grooves 13 are opposite, the bottom of the sliding groove 13 is provided with a blocking plate 18, the closest distance between the two blocking plates 18 is less than the distance between the notches of the two sliding grooves 13, namely, if the notch of the sliding groove 13 faces upwards, the height of the blocking plate 18 is less than the height of the notch.

A sliding cylinder 14 is arranged between the two sliding chutes 13, the sliding cylinder 14 is flat, two ends of the sliding cylinder 14 are overlapped in the sliding chutes 13, two sliding plates 15 are arranged on two sides of the upper end of the sliding cylinder 14, the sliding plates 15 are positioned in the sliding chutes 13 and can slide along the sliding chutes 13, the width of the sliding cylinder 14 is smaller than the nearest distance between the two blocking plates 18, namely, the sliding cylinder 14 can slide down from between the two sliding chutes 13 as a whole, but the blocking plates 18 block the sliding plates 15, so that the length of the sliding chutes 13 is prolonged equivalently.

Two squeezing rollers 16 are arranged at the lower end of the sliding cylinder 14, and the connecting line of the central lines of the two squeezing rollers 16 is vertical to the plane of the sliding cylinder 14.

The winding shaft 7 is wound with the waterproof cloth 10, the waterproof cloth 10 downwards passes through a gap between the sliding cylinder 14 and the two squeezing rollers 16 and then is connected with a gravity rod 17, and the length of the gravity rod 17 is longer than the width of the sliding cylinder 14. The combination of the reel 7 and the waterproof cloth 10 is equivalent to a guardrail for one-meter line arranged in a bank, but the guardrail automatically rebounds, and the embodiment is wound by a crank.

The width of the slide cartridge 14 is such that there is no gap or only a slight gap between the waterproof cloth and the slide groove.

In order to reduce the weight, the push-pull tripod 20, the sliding groove 13, the reel 7, the sliding cylinder 14, the roller 19 and the like are all made of plastic, and the gravity rod 17 can be made of metal or plastic.

The cavity 4 is provided with the slouch door 5, namely the upper end of the slouch door 5 is hinged at the front end of the cavity 4, then the slouch door 5 is provided with the handle 6, the upper end of the box door 2 is slightly higher than the lower end of the slouch door 5, and the slouch door 5 can not be opened as long as the box door 2 is closed.

In order to adapt to dim weather, a solar cell panel 21 is arranged on the box body 1, an emergency lamp 22 is arranged in the box body 1, and the emergency lamp 22 is powered by the solar cell panel 21.

The using process is as follows: after the box door 2 is opened, the door 5 is lifted to slide down, the push-pull tripod 20 is pulled out until the door is immovable, at this time, under the action of the gravity rod 17 and the self gravity of the sliding cylinder 14, the sliding cylinder 14 slides downwards until the door is immovable, the gravity rod 17 continues to drive the rain-proof cloth 10 to slide down until the rain-proof cloth 10 is completely unfolded from the reel 7, and thus the two rain-proof cloths 10 and the rain-proof cover 11 form a rain-proof cover.

After maintenance is finished, the handle 6 is rotated, the waterproof cloth 10 is wound on the reel 7 again, the gravity rod 17 is driven to rise upwards, and in the winding process of the waterproof cloth 10, on one hand, the waterproof cover 11 scrapes rainwater or snow on the waterproof cloth 10, and on the other hand, the two squeezing rollers 16 scrape rainwater (because the part is suspended, snow generally does not exist); when the gravity rod 17 rises to the squeeze roller 16, the gravity rod 17 continues to slide the sliding cylinder 14 upwards until the gravity rod 17 is lifted. Then the push-pull tripod 20 is pushed into the cavity 4, the door 5 hangs down naturally, and the door 2 is closed. If the gravity rod 17 is too light or the squeezing roller 16 is pressed too tightly, the waterproof cloth cannot naturally droop, and the gravity rod 17 can be pulled down manually.

Other technical features than those described in the specification are known to those skilled in the art.
