Abstract
The utility model relates to a kind of door-rolling machine slow descending device for preventing rolling door and ground shock from damaging, and comprises shell, spring, piston block, rotating shaft and jump ring; Piston block be connected on the left of rotating shaft and be installed in shell; Spring fitting between piston block and shell bottom plate, side and shell bottom plate affixed; Jump ring is arranged in shell jump-ring slot.Be provided with helicla flute on the left of rotating shaft, be provided with the spiral boss corresponding with helicla flute in piston block, piston block and rotating shaft spiral are socketed.This device can realize slowing down in rolling door decline process, reduces the impact between rolling door and ground, prevents rolling door from damaging.
Description
Technical field
The utility model relates to slow descending device technical field, particularly a kind of slow descending device on door-rolling machine.
Background technology
Rolling door does not generally establish slow descending device in decline process, easily occurs impact thus cause rolling door to be damaged in the process of landing.The utility model is exactly mainly devise a kind of structure, slows down in rolling door decline process, reduces the impact between rolling door and ground, prevents rolling door from damaging.
Utility model content
It is simple that technical problem to be solved in the utility model is to provide a kind of structure, and safe and reliable door-rolling machine slow descending device, can realize slowing down in rolling door decline process, reduce the impact between rolling door and ground, prevent rolling door from damaging.
For solving the problems of the technologies described above, the utility model realizes as follows: a kind of door-rolling machine slow descending device described in the utility model comprises shell, spring, piston block, rotating shaft and jump ring; Piston block be connected on the left of rotating shaft and be installed in shell; Spring fitting between piston block and shell bottom plate, side and shell bottom plate affixed; Jump ring is arranged in shell jump-ring slot.
Be provided with helicla flute on the left of described rotating shaft, be provided with the spiral boss corresponding with helicla flute in piston block, piston block and rotating shaft spiral are socketed.
Good effect of the present utility model: a kind of door-rolling machine slow descending device structure described in the utility model is simple, can be connected in each door-rolling machine rotating shaft easily, can realize slowing down in rolling door decline process, reduce the impact between rolling door and ground, prevent rolling door from damaging, reliability is high, and cost is low, is suitable for extensive popularization.

Detailed description of the invention
As shown in Figure 1 and Figure 2, a kind of door-rolling machine slow descending device described in the utility model comprises shell (1), spring (2), piston block (3), rotating shaft (4) and jump ring (5); Piston block (3) is connected with rotating shaft (4) left side and is installed in shell (1); Spring (2) is arranged between piston block (3) and shell (1) base plate, side and shell (1) base plate affixed; Jump ring (5) is arranged in shell (1) jump-ring slot.
Described rotating shaft (4) left side is provided with helicla flute, and piston block is provided with the spiral boss corresponding with helicla flute in (3), and piston block (3) and rotating shaft (4) spiral are socketed.
The course of work of the present utility model:
A kind of door-rolling machine slow descending device described in the utility model can be connected in each door-rolling machine rotating shaft by shaft coupling, the situation lower rotary shaft (4) declined in rolling door also rotates thereupon, due to piston block (3) and rotating shaft (4) for spiral is socketed, rotating shaft (4) revolving force is converted to the thrust of piston block (3), make piston block (3) mobile to the left and Compress Spring (2), the elastic force formed after spring (2) compression makes the resistance of piston block (3) movement to the left become greatly, cause piston block (3) slowing in axis, the rotating speed of rotating shaft simultaneously (4) is also thereupon slack-off, thus reach rolling door and delay the effect of falling.
Some principles of work and power of a kind of door-rolling machine slow descending device that the utility model that just explains through diagrams recited above is correlated with; be easy to carry out some amendments on this basis due to the technician concerning constructed field; therefore this manual does not really want a kind of door-rolling machine slow descending device described in the utility model to be confined in shown or described concrete mechanism and the scope of application; therefore every corresponding modify that may be utilized and equivalent, all belong to the protection domain of the utility model patent.
Claims (2)
