[0003] The positions of the transmitting and receiving ends in the existing safety grating are fixed, so that the ray spacing of the safety grating in the vertical direction is fixed. Since the safety grating is used in different scenarios, rays with different spacings are required. If the ray spacing is too small, it is easy to cause high energy consumption problems. If the ray spacing is too large, it is easy to cause security protection loopholes.

[0004] Therefore, an adjustable safety light grid is proposed. Utility Model Content

[0007] Preferably, a through cavity communicated with the mounting groove is formed on one side outer wall of the shell, and a through groove communicated with the storage cover is formed on the other side outer wall of the shell.

[0008] Preferably, a transmitter or a receiver is installed at a central position of an outer wall on a side of the transmitter / receiver mounting platform away from the socket.

[0009] Preferably, the sliding block is located inside the sliding groove, and the sliding block and the sliding groove are slidably connected.

[0010] Preferably, the embedding block and the embedding groove match each other, and the cross-sections of the embedding block and one end of the embedding groove are both isosceles trapezoidal structures.

[0011] Preferably, a limiting hole for the limiting rod to pass through is opened on one side outer wall of the movable plate.

[0012] Preferably, the plug can be inserted into the socket, and the plug and the socket are electrically connected.

[0013] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0014] The positioning of the transmitter / receiver mounting platform at different heights in the mounting groove is achieved by sliding the transmitter / receiver mounting platform in the mounting groove and positioning and limiting the embedded block after it is inserted into the embedded groove. The spacing between adjacent transmitter / receiver mounting platforms is then adjusted as needed, thereby adjusting the ray interval to facilitate adapting to different safety protection needs.

The transmitter or the receiver is used to make the shell 1 have a grating function, and the shell 1 has a grating function. A storage cover 11 is fixedly connected to the outer wall of one side of the housing 1 by bolts, and a threaded rod 12 is screwed and connected to the central position of the outer wall of the storage cover 11 away from the housing 1 by threaded engagement, and one end of the threaded rod 12 is rotatably connected to a movable plate 13, and a plug 14 is provided on the outer wall of the movable plate 13 away from the threaded rod 12.

Through the mutual cooperation of the limit rod 15 and the limit hole, the movable plate 13 can move in a straight line. The outer shell 1 and the top of the storage cover 11 are fixedly connected with a shell cover 17 by bolts.

[0024] It should be noted that since the positions of the transmitter and the receiver in the existing safety grating are fixed, the ray interval in the vertical direction of the safety grating is fixed. Since the safety grating is used in different scenarios, rays with different intervals are required. If the ray interval is too small, it is easy to cause high energy consumption problems. If the ray interval is too large, it is easy to cause security protection loopholes. In this embodiment, the transmitter / receiver mounting platform 5 is positioned at different heights in the mounting groove 2 by sliding the transmitter / receiver mounting platform 5 in the mounting groove 2 and positioning and limiting the embedding block 9 after it is inserted into the embedding groove 4, and then the distance between adjacent transmitter / receiver mounting platforms 5 is adjusted according to needs, thereby adjusting the ray interval to adapt to different safety protection needs. The modular adjustment and assembly of the transmitter / receiver mounting platform 5 is realized through the adjustable combined structure, thereby improving the scenarios in which the safety grating is used.

[0025] Specifically, in this embodiment, this scheme mainly includes a transmitter / receiver mounting platform 5, and the transmitter or the receiver is mounted on the outer wall of the transmitter / receiver mounting platform 5. When adjusting and assembling, the transmitter / receiver mounting platform 5 is inserted into the mounting groove 2, and the transmitter / receiver mounting platform 5 is moved in the mounting groove 2 by sliding the slider 6 in the slide groove 3. When the transmitter / receiver mounting platform 5 moves in the mounting groove 2, the embedded block 9 is squeezed by the inner wall of the slide groove 3 and then stored in the groove 7, and the spring 8 is compressed. When the embedded block 9 moves to one side of the embedded groove 4, the extrusion force on the embedded block 9 disappears, and under the action of the rebound force of the spring 8, the embedded block 9 is pushed and inserted into the embedded groove 4. Slot 4, realizes the positioning of the transmitter / receiver mounting platform 5 in the internal position of the mounting slot 2, adjusts the interval between adjacent transmitter / receiver mounting platforms 5 and performs positioning and limiting according to the spacing of adjacent rays in the vertical direction required by the safety grating, and after completing the installation and positioning of the transmitter / receiver mounting platform 5, rotates the disk 16, and the disk 16 drives the threaded rod 12 to rotate. Through the threaded screw connection between the threaded rod 12 and the storage cover 11, one end of the threaded rod 12 pushes the movable plate 13 to move, and the plug 14 on the movable plate 13 is inserted into the socket 10 on the transmitter / receiver mounting platform 5. The plug 14 is inserted into the socket 10 to provide power for the transmitter or receiver installed on the transmitter / receiver mounting platform 5.

[0026] In a further preferred embodiment of the present invention, Figure 1 , Figure 2 and Figure 5 As shown, a through cavity communicating with the mounting groove 2 is formed on one side of the outer wall of the housing 1 , and a through groove communicating with the storage cover 11 is formed on the other side of the outer wall of the housing 1 .

[0027] In this embodiment, the setting of the through cavity can allow the rays emitted by the transmitter installed on the transmitter / receiver mounting platform 5 to radiate out, and the two shells 1 are combined to form a safety grating. The setting of the through groove can allow the plug 14 to be inserted into the socket 10, thereby providing power to the transmitter or receiver installed on the transmitter / receiver mounting platform 5.

[0028] In a further preferred embodiment of the present invention, Figure 2 and Figure 4 As shown, the embedding block 9 and the embedding groove 4 match and fit together, and the cross-sections of the embedding block 9 and one end of the embedding groove 4 are both isosceles trapezoidal structures.

[0029] In this embodiment, the positioning of the transmitter / receiver mounting platform 5 inside the mounting groove 2 is achieved by embedding the embedding block 9 into the embedding groove 4, and then the distance between adjacent transmitter / receiver mounting platforms 5 is adjusted according to needs, thereby adjusting the ray interval to adapt to different safety protection needs.
