Description

Technical Field

[0001] The invention relates to the field of light curtain configuration cascade equipment, in particular to a portable quick-detachable light curtain configuration cascade equipment. Background Art

[0002] At present, the application scope of light curtains is very wide, and they have achieved very good results in practical applications, which has promoted the application of light curtains. Affected by the shape of the light curtain shell, it is sometimes necessary to connect multiple light curtain systems to expand the detection range or improve the protection effect. Through cascading, detection of a larger surrounding area can be achieved.

[0003] According to the published patent 201920945089.7, a cascade light curtain includes a light curtain body, a protective shell and a base. A protective shell is provided on the outside of the light curtain body, and a base is provided at the bottom end of the protective shell. One end of the base is connected to a movable rod through a rotating shaft 1, and the movable rod is connected to a fixed seat through a rotating shaft 2. Fixing holes are provided at the four corners of the fixed seat. A clamping device is installed inside the protective shell. In the utility model, because the threads on the threaded rod 1 and the threaded rod 2 are opposite, and the movable block slides along the movable groove, the threaded sleeve 1 and the threaded sleeve 2 are limited, so that the two connecting rods and the clamping plates move relative to each other. When the two clamping plates are close, the two ends of the light curtain body are clamped, and the adjusting bolt is rotated so that the pressure plate fixes the top of the light curtain body, thereby realizing the installation of the light curtain body. The protective shell protects the light curtain body to prevent the light curtain body from being damaged by external force when it is working. In the process of realizing the present invention, the inventor found that at least the following problems in the prior art have not been solved. Although the light curtain body is installed in the protective shell The clamping device is used to clamp the light curtain body. When the clamping device is used, the turntable is rotated to drive the adjusting shaft and the active bevel gear to rotate, so that the driven bevel gear 1 and the driven bevel gear 2 are rotated, so that the threaded rod 1 and the threaded rod 2 are rotated, and the threaded sleeve 1 and the threaded sleeve 2 are moved left and right. Because the threads on the threaded rod 1 and the threaded rod 2 are opposite, and the movable block slides along the movable groove, the threaded sleeve 1 and the threaded sleeve 2 are limited, so that the two connecting rods and the clamping plate move relative to each other. When the two clamping plates are close, the two ends of the light curtain body are clamped, and the adjusting bolt is rotated so that the pressure plate fixes the top of the light curtain body, thereby realizing the installation of the light curtain body. The protective shell protects the light curtain body and prevents the light curtain body from being damaged by external force when working. However, during use, the traditional light curtain configuration cascade device is large in size and heavy in weight. Moreover, when the light curtain is disassembled and connected, the operation process is cumbersome, and multiple bolts need to be disassembled and installed, resulting in a slow speed of disassembly and connection of the light curtain, which affects the efficiency of the cascade deployment of the light curtain and is not conducive to flexible carrying and rapid deployment. Therefore, it is necessary to design a new technical solution. Summary of the invention

[0020] The present invention is further described below in conjunction with the accompanying drawings and embodiments:

[0021] A portable quick-detachable light curtain configuration cascade device, see Figures 1 to 4 , including a device housing 1, a measuring unit 11 is arranged inside the device housing 1, and the measuring unit 11 includes a signal transmitting end and a signal receiving end. The signal transmitting end and the signal receiving end use the signal transmitting tube group and the signal receiving tube group in the measuring unit 11 to complete the transmission and reception of the signal; the two ends of the measuring unit 11 are respectively installed with a spring end 6 and a contact piece end 2, and both the spring end 6 and the contact piece end 2 are built with magnets; a support seat is installed on one side of the bottom of the device housing 1. Since the two ends of the measuring unit 11 are respectively provided with a spring end 6 and a contact piece end 2, a plurality of measuring units 11 can form an integral light curtain circuit after being connected end to end. Different lengths of light curtains can be deployed by selecting different numbers of nodes according to different equipment requirements: the electrical connection is connected by upper and lower rows of 6-pin springs 9, of which 2 pins are power lines and 4 pins are signal lines. Any group of the upper and lower rows of springs 9 can be turned on to achieve electrical connection. The springs 9 have a compression amount of about 2.5 mm, which can redundancy The angle deviation between the measuring units 11 caused by the uneven bottom surface can be redundant.

[0022] For details, see Figure 1 The surface of the contact piece end 2 is raised, and multiple contact pieces 4 are installed at the raised position. Support columns 3 are fixed at the four corners of the contact piece end 2 to protect the raised contact piece 4 structure. The contact piece end 2 adopts a raised design, and the corresponding spring piece end 6 adopts a concave design to protect the spring piece 9 and reduce the probability of damage. At the same time, the combination of the concave and convex structure can achieve an excellent positioning effect to ensure that the contact piece 4 and the spring piece 9 are in full contact and not misaligned, thereby achieving an excellent electrical connection.

[0023] For further information, see Figure 2An embedded groove 8 is provided on the surface of the spring piece end 6, and a plurality of spring pieces 9 are installed in the embedded groove 8. Grooves 7 matching the support column 3 are provided at the four corners of the surface of the spring piece end 6.

[0024] It is worth noting that see Figure 3 The support base includes a support foot pad 5 and a concave limit baffle 10. The support foot pad 5 is integrated with a concave limit baffle 10. After the measuring unit 11 is cascaded, the two sides of the concave limit baffle 10 will have a limiting effect on the connection position shell. The precise tolerance can make the deflection angle of adjacent units less than 1°, thereby ensuring the normal operation of the entire system.

[0025] It is worth noting that see Figure 3 A concave limiting baffle 10 is installed on the top of the supporting foot pad 5, and the concave limiting baffle 10 is used to limit the two ends of multiple docking device housings 1.
