[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Example

[0023] See also Figure 1-3 , this embodiment provides a safety railing, including a base 1, an electric telescopic rod 3 is rotatably connected to the inner side of the base 1, a small curved tube 4 is connected to the top of the electric telescopic rod 3, one end of the small curved tube 4 is threadedly connected to a double-headed screw 5, one end of the double-headed screw 5 is threadedly connected to a large curved tube 6, an alarm 7 is connected to the large curved tube 6, one end of the alarm 7 is connected to a retractable straight tube 8, a protective cover 2 is installed at one end of the base 1, a pressure sensor 21 is installed on the inner side of the protective cover 2, one end of the pressure sensor 21 is fitted with one end of the electric telescopic rod 3, and when the pressure of the electric telescopic rod 3 squeezing the pressure sensor 21 is greater than the set value when the electric telescopic rod 3 rotates, the alarm 7 sounds an alarm when the safety railing is in use, through the electric The railing composed of the movable telescopic rod 3, the small curved pipe 4, the large curved pipe 6 and the straight pipe 8 is used to block the position where the materials are stacked. One end of the material can be placed against the inner side of the railing. At the same time, the railing is installed at a position at the distance of a safe passage at one end between the machine. When the material is moved to one end of the machine, the electric telescopic rod 3 will rotate in the direction of the protective passage 2 under the squeezing of the material. At this time, the electric telescopic rod 3 will squeeze the pressure sensor 21. When the squeezing force at this time exceeds the pressure value set by the pressure sensor 21, the alarm 7 will sound an alarm to remind employees that the material has exceeded the safe placement position and needs to be readjusted, thereby ensuring the distance between the material and the machine, reserving a safe passage for employees to escape, and improving production safety.

[0024] In this embodiment, if Figure 1 and Figure 2As shown, bolts 12 are connected between the two sides of the base 1. The bolts 12 pass through the part of the electric telescopic rod 3 located on the inner side of the base 1. The electric telescopic rod 3 can rotate on the bolts 12. After the bolts 12 are tightened, the rotation angle of the electric telescopic rod 3 can be fixed. Therefore, within a certain pressure range, the electric telescopic rod 3 will not rotate. When the extrusion force exceeds the bearing capacity of the electric telescopic rod 3, the electric telescopic rod 3 will rotate on the inner side of the base 1, thereby preventing the electric telescopic rod 3 from accidentally hitting the pressure sensor 21 frequently and causing the alarm 7 to sound an alarm.

[0025] In this embodiment, if Figure 1 and Figure 2 As shown, one end of the pressure sensor 21 extends into the interior of the base 1 and fits into the vertical electric telescopic rod 3. One end of the pressure sensor 21 is connected to a spring 22, and one end of the spring 22 is fixedly connected to the inner wall of the protective cover 2. When the electric telescopic rod 3 squeezes the pressure sensor 21, the pressure sensor 21 can be squeezed into the protective cover 2 to prevent damage caused by excessive squeezing force.

[0026] In this embodiment, if Figure 1 and Figure 3 As shown, screw rods 51 are installed at both ends of the double-headed screw 5, and the screw rods 51 at both ends of the double-headed screw 5 are respectively threadedly connected to one end of the small bend pipe 4 and the large bend pipe 6. When the double-headed screw 5 is rotated, the distance between the small bend pipe 4 and the large bend pipe 6 can be changed. There are two straight pipes 8, and a sleeve 9 is connected between the two straight pipes 8. The two ends of the sleeve 9 are respectively inserted into one end of the two straight pipes 8 and slidably connected. Therefore, when the double-headed screw 5 is rotated, the distance between the two straight pipes 8 will change with the distance between the small bend pipe 4 and the large bend pipe 6, so that the protection range of the safety railing can be adjusted, thereby improving the applicability of the safety railing.

[0027] Working principle: When the safety railing is in use, the position where the materials are stacked is blocked by a railing composed of an electric telescopic rod 3, a small curved pipe 4, a large curved pipe 6 and a straight pipe 8. One end of the material can be placed against the inner side of the railing. At the same time, the railing is installed at a position at the distance of a safety passage at one end between the machine and the material. When the material is moved toward one end of the machine, the electric telescopic rod 3 will rotate in the direction of the protective passage 2 under the squeezing of the material. At this time, the electric telescopic rod 3 will squeeze the pressure sensor 21. When the squeezing force at this time exceeds the pressure value set by the pressure sensor 21, the alarm 7 will sound an alarm to remind employees that the material exceeds the safe placement position and needs to be readjusted, thereby ensuring the distance between the material and the machine, reserving a safe passage for employees to escape, and improving production safety. At the same time, when the double-headed screw 5 rotates, the distance between the two straight pipes 8 will change with the distance between the small curved pipe 4 and the large curved pipe 6, so that the protection range of the safety railing can be adjusted to improve the applicability of the safety railing.

[0028] All technical features in this embodiment can be freely combined according to actual needs.

[0029] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
