[0002] In modern factories, some mechanical equipment with potential danger, such as punching machines, shearing equipment, metal cutting equipment, mechanical conveying and handling equipment, etc., are easy to cause personal injury to workers. If a light curtain is installed on these mechanical equipment, the light curtain can emit infrared rays to generate a protective light curtain. When the protective light curtain is blocked, the light curtain sends a light blocking signal to remind the mechanical equipment to stop working, which can avoid safety accidents.

Figure 4 A structural schematic view of a first mounting member and a first connecting member provided for some embodiments of the present application. Referring to Figures 1-4 The light curtain support provided by the embodiments of the present application comprises a first mounting member 01, a second mounting member 02, a first connecting member 03, a second connecting member 04 and a support 05. The first mounting member 01 is connected with the first connecting member 03, and the first mounting member 01 and the first connecting member 03 are perpendicular to each other. The second mounting member 02 is connected with the second connecting member 04, and the second mounting member 02 and the second connecting member 04 are perpendicular to each other. The support 05 is connected with the second connecting member 04, and the support 05 and the second connecting member 04 are perpendicular to each other. The first mounting member 01 is connected with a mounting surface 06, and the second mounting member 02 is connected with a light curtain 07. The first connecting member 03 is provided with a first circular through hole 031. The second connecting member 04 is provided with a second circular through hole. The support 05 is provided with a third circular through hole 051.

[0041] When the light curtain support is installed, the first connecting member 03 is sleeved outside the support 05 through the first circular through hole 031. The first connecting member 03 and / or the second connecting member 04 is / are rotated to a suitable angle and then fixed. A cable 08 connected with the light curtain 07 passes through the second circular through hole, the third circular through hole 051 and the first circular through hole 031 in sequence.

[0042] It should be noted that the first mounting member 01 and the first connecting member 03 can be an integrally formed structure. The second mounting member 02 and the second connecting member 04 can be an integrally formed structure. The shape of the first mounting member 01, the second mounting member 02, the first connecting member 03 and the second connecting member 04 is not limited in the present application.

[0044] In some embodiments, the support member 05 may be formed by extending axially from the side of the second circular through hole near the first connector 03. This axial extension of the support member 05 from the side of the second circular through hole near the first connector 03 is one form in which the support member 05 and the second connector 04 are interconnected.

[0045] For example, support member 05 can be formed by stamping and flanging a second circular through hole.

In some embodiments, reference is made to… Figure 5 The support member 05 may include multiple support arms 052, which are circumferentially spaced and surround a third circular through hole 051. For example, the support member 05 may include four support arms 052, which are circumferentially spaced and surround a third circular through hole 051.

[0047] In some embodiments, the light curtain bracket may further include one or more first bolts 09, the first connector 03 has one or more fourth through holes 032, and the second connector 04 has one or more first threaded holes 041. The first connector 03 and / or the second connector 04 can be rotated to a suitable angle and then fitted together, specifically including: the first connector 03 and / or the second connector 04 rotate to a suitable angle and then fit together, and the first bolt 09 passes through the fourth through hole 032 and is threadedly connected to the first threaded hole 041, so as to fix the first connector 03 and the second connector 04.

[0048] For example, there can be two first bolts 09, four fourth through holes 032, and four first threaded holes 041. The fourth through holes 032 can be evenly spaced along the circumference of the first circular through holes 031, and the two first threaded holes 041 are respectively set to correspond to the two fourth through holes 032, and the two first threaded holes 041 and the fourth through holes 032 are staggered.

For example, the second bolts 10, the first nuts, and the fifth through holes 011 can all be two. The mounting surface 06 is provided with a seventh through hole. The second bolts 10 pass through the fifth through holes 011, the seventh through hole, and are matched with the first nuts to connect the first mounting member 01 and the mounting surface 06.

[0056] In practical applications, the fifth through hole 011 can be a waist-shaped hole. In this way, fine adjustment of the connection between the first mounting member 01 and the mounting surface 06 can be achieved.
