[0022] In order to make the purpose, technical solutions and advantages of the implementation methods of this application clearer, the technical solutions in the implementation methods of this application will be clearly and completely described below in conjunction with the drawings in the implementation methods of this application. Obviously, the described implementation methods are part of the implementation methods of this application, not all of the implementation methods. Based on the implementation methods in this application, all other implementation methods obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] like Figure 1-Figure 4 As shown, a safety grating according to an embodiment of the present application includes a grating body 1, the grating bodies 1 are arranged in pairs, and signal end faces 2 are arranged on the paired grating bodies 1. Specifically, the signal end faces 2 are divided into a signal transmitting end and a signal receiving end, and the signal transmitting end and the signal receiving end are respectively installed on the two grating bodies 1, wherein the paired grating bodies 1 are provided with protective components 3 of the same structure and size, and the protective components 3 are limitedly slid on the side of the grating body 1 where the signal end faces 2 are installed, and the protective components 3 protect the signal end faces 2.

[0024] Furthermore, a mounting groove 11 is provided on one side of the grating body 1 away from the signal end face 2, and a mounting frame 12 is fixed to the mounting groove 11 by bolts, so as to facilitate adjustment of the specific position of the mounting frame 12 on the grating body 1 so as to install the paired grating bodies 1 on actual production equipment for use.

[0025] Furthermore, a receiving groove 13 is provided on one side of the grating body 1 where the signal end face 2 is provided, and the receiving groove 13 is arranged in an arc shape.

[0026] Furthermore, the grating body 1 is provided with a signal end face 2 on one side with limit sliding grooves 14 symmetrically arranged at the top and bottom ends, and the limit sliding grooves 14 are arranged in a U shape.

[0027] Furthermore, the protective assembly 3 includes a protective baffle 31, limit members 32 symmetrically arranged at the top and bottom ends of the protective baffle 31, and a connecting pin 33 fixedly connecting the two limit members 32, wherein the protective baffle 31 and the storage groove 13 are slidably matched, the limit member 32 and the limit slide groove 14 are slidably matched, and the connecting pin 33 slides through the protective baffle 31.

[0028] It should be noted that the protective baffle 31 can be made of a rigid material with elastic deformation, such as a metal sheet made of steel, etc., which has both protective capability and deformation capability so as to be smoothly stored in the storage slot 13.

[0029] Furthermore, the limiting member 32 includes a displacement block 321, a T-shaped slider 322 is fixedly connected to one side of the displacement block 321, the T-shaped slider 322 and the limiting slide groove 14 are slidably matched, and a protrusion 323 is fixedly connected to the side of the displacement block 321 away from the T-shaped slider 322, wherein the protrusion 323 facilitates the staff to pull the displacement block 321 to displace.

[0030] Furthermore, connecting pins 33 are fixedly connected between the symmetrically arranged displacement blocks 321 .

[0031] Furthermore, a tension spring 331 is sleeved on the connecting pin 33 , one end of the tension spring 331 is fixedly connected to the top end surface of the protective baffle 31 , and the other end of the tension spring 331 is fixedly connected to the displacement block 321 at the top.

[0032] It can be understood that when the grating body 1 is not in use, the protrusion 323 is pulled to cause the displacement block 321 to move upward along the vertical end (the two vertical ends of the U-shaped) of the top limiting slot 14, and then move along the lateral end of the limiting slot 14. In this process, since the displacement block 321 moves upward, the tension spring 331 is stretched, and the height of the protective baffle 31 does not change, the tension spring 331 generates a downward pulling force on the displacement block 321. While the displacement block 321 moves, the protective baffle 31 will also move synchronously, and then the protective baffle 31 slides out of the storage slot 13, gradually covering the signal end face 2, until the displacement block 321 moves to the other side of the limiting slot 14 In the vertical end of one side, the displacement block 321 is limited by the vertical end of the U-shaped limiting slide groove 14 and cannot be displaced along the lateral end of the limiting slide groove 14. Under the action of the tension of the tension spring 331, the displacement block 321 cannot be displaced from the vertical end on one side of the limiting slide groove 14 to the vertical end on the other side without external interference. Then, the protective baffle 31 is used to fully cover the signal end face 2 to realize the protection function and prevent foreign objects from hitting the signal end face 2. On the contrary, when the signal end face 2 needs to be used, it only needs to move the displacement block 321 from the vertical end on this side of the limiting slide groove 14 to the vertical end on the other side to leak the signal end face 2.

[0033] It should be noted that the specific model specifications of the grating body 1 and the tension spring 331 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0034] The above are only preferred implementations of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
