Description

Technical Field

[0001] The utility model relates to the technical field of photoelectric switches, in particular to a photoelectric switch bracket and a photoelectric switch device. Background Art

[0002] During pipeline production, in the related art, a photoelectric switch is often set at a certain height beside the pipeline to identify the highest position of the material accumulation during the production process through the photoelectric switch, so as to judge the storage situation of the incoming material, monitor whether the material is flowing at a stable flow rate during the production process, and then be able to cooperate with the control module to adjust the speed of the material flow from the upstream, so as to maintain the continuity and uniformity of the downstream work of the pipeline, thereby ensuring the product quality. It can be seen that the photoelectric switch plays a very important role in ensuring the production safety and product quality of the production line.

[0003] When it is necessary to adjust the flow requirement of the material, it is necessary to adjust the height of the photoelectric switch to adjust the highest position of the material accumulation suitable for detection by the photoelectric switch, and then adjust the material flow detected by the photoelectric switch. However, the current photoelectric switch is prone to looseness after the position is adjusted, resulting in poor position stability of the photoelectric switch, and then reducing the detection accuracy of the highest position of the material accumulation on the pipeline. The actual material flow on the pipeline has a large gap from the predetermined material flow requirement, and it can further lead to a decrease in the product yield of the production line.

[0037] To make the technical problems solved by the present utility model, the technical solutions adopted and the achieved technical effects clearer, the technical solutions of the embodiments of the present utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

The first feature being "below", "under" and "beneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.

[0040] As Figures 1 to 3 shown, the present utility model provides an optoelectronic switch bracket 1001, which includes a fixing structure 1 and a bearing structure 2. The fixing structure 1 includes a fixing seat 10 and at least three ribs 11 provided on the fixing seat 10. All the ribs 11 are arranged at intervals along a first direction S1. A setting groove 12 is formed between any two adjacent ribs 11. Thus, the fixing structure 1 has a plurality of setting grooves 12 arranged at intervals along the first direction S1. The bearing structure 2 includes a bearing seat 20, a threaded member 21 and a fixing member 22. The bearing seat 20 is used for bearing an optoelectronic switch. The bearing seat 20 is provided with a first hole 201 penetrating along the first direction S1 and a second hole 202 penetrating along a second direction S2. A part of the fixing structure 1 is located in the first hole 201 and is slidably and fit-connectively connected to the first hole 201 along the first direction S1. The second hole 202 includes a first sub-hole 2021 and a second sub-hole 2022 arranged in sequence along the second direction S2. A part of the threaded member 21 is located in the first sub-hole 2021 and is rotatably connected to the first sub-hole 2021. The end of the threaded member 21 extends into the second sub-hole 2022. The second sub-hole 2022 communicates with the first hole 201. The fixing member 22 is slidably and fit-connectively connected to the second sub-hole 2022 along the second direction S2, and the fixing member 22 is provided with a threaded hole 220 extending along the second direction S2. The end of the threaded member 21 is threadedly connected to the threaded hole 220. The end of the fixing member 22 away from the threaded member 21 can be correspondingly inserted into the setting groove 12, wherein the first direction S1 is perpendicular to the second direction S2.

[0041] By making the photoelectric switch bracket 1001 include a fixing structure 1 and a bearing structure 2, forming a plurality of setting grooves 12 in the fixing structure 1, making the bearing structure 2 include a threaded member 21 rotatably connected to the bearing seat 20 and a fixing member 22 slidably connected to the bearing seat 20, and making the fixing member 22 threadedly connected to the threaded member 21, it is possible to drive the fixing member 22 to expand and contract in the second sub-hole 2022 along the second direction S2 by rotating the threaded member 21. When the fixing member 22 retracts into the second sub-hole 2022, the bearing structure 2 can slide relative to the fixing structure 1 along the first direction S1 to adjust the relative position between the bearing structure 2 and the fixing structure 1. When the end of the fixing member 22 extends out of the second sub-hole 2022, the end of the fixing member 22 can be inserted into the setting groove 12 corresponding to the current position, so that the relative position between the bearing structure 2 and the fixing structure 1 is kept stable, and thus the bearing structure 2 can carry the photoelectric switch and stably maintain it at a predetermined position.

[0042] Optionally, the aperture of the first sub-hole 2021 is smaller than the aperture of the second sub-hole 2022. A step surface 2023 facing the inside of the second sub-hole 2022 is formed at the connection between the first sub-hole 2021 and the second sub-hole 2022. The bearing structure 2 further includes a first limiting member 23. The first limiting member 23 is located in the second sub-hole 2022 and fixed to the outer periphery of the threaded member 21. The first limiting member 23 can abut against the step surface 2023, so as to limit the position of the threaded member 21 and prevent the threaded member 21 from moving out of the first sub-hole 2021 along the direction away from the second sub-hole 2022. It can be understood that during the installation process, the threaded member 21 can be first passed through the first sub-hole 2021 so that one end is located in the second sub-hole 2022, and then the first limiting member 23 is placed in the second sub-hole 2022, and the first limiting member 23 and the threaded member 21 are connected by means including but not limited to threaded connection, welding, and bonding.

[0043] Optionally, the first limiting member 23 can be of a structure including but not limited to a ring shape or a block shape. Among them, when the first limiting member 23 is in a ring shape, the first limiting member 23 can be sleeved on the outer periphery of the threaded member 21, and the limiting effect of the first limiting member 23 on the threaded member 21 is more balanced.

[0044] Optionally, the shape of the end of the fixing member 22 can be adapted to the shape of the setting groove 12. Thus, when the end of the fixing member 22 is inserted into the setting groove 12, the connection tightness between the fixing member 22 and the setting groove 12 is better, so that the relative position stability between the fixing member 22 and the fixing structure 1 is better, and further the photoelectric switch bracket 1001 can carry the photoelectric switch and maintain it more stably at a predetermined position.

[0045] Exemplarily, the setting groove 12 may include a first wall surface 121 and a second wall surface 122 spaced apart relatively along a first direction S1, and a third wall surface 123 connected between the first wall surface 121 and the second wall surface 122. The end of the fixing member 22 may have a first surface 221, a third surface 223, and a second surface 222 connected in sequence. When the end of the fixing member 22 is correspondingly inserted into the setting groove 12, the first surface 221 abuts against the first wall surface 121, the second surface 222 abuts against the second wall surface 122, and the third surface 223 abuts against the third wall surface 123.

[0046] Preferably, both the first wall surface 121 and the first surface 221 are perpendicular to the first direction S1. Thus, the photoelectric switch bracket 1001 can be set in a posture with the first direction S1 parallel to the gravity direction. When the end of the fixing member 22 is correspondingly inserted into the setting groove 12, the first wall surface 121 is located below the first surface 221 along the gravity direction, so that the first wall surface 121 is more suitable for supporting the end of the fixing member 22. Furthermore, the photoelectric switch bracket 1001 can carry the photoelectric switch and maintain it more stably at a predetermined position.

[0047] In addition, by setting the photoelectric switch bracket 1001 in a posture with the first direction S1 parallel to the gravity direction, the position height of the photoelectric switch carried by the carrying structure 2 along the gravity direction can also be adjusted by adjusting the relative position of the carrying structure 2 relative to the fixing structure 1 along the first direction S1.

[0048] Optionally, a first setting hole 203 is further provided on the surface of the carrying seat 20, a locking hole 210 is further provided on the outer periphery of the threaded member 21, the locking hole 210 communicates with the first sub-hole 2021, one end of the first setting hole 203 communicates with the first sub-hole 2021. The carrying structure 2 further includes a locking assembly 3. The locking assembly 3 includes a locking member 31, a second limiting member 32, and an elastic member 33. The locking member 31 is detachably connected to the first setting hole 203, and the locking member 31 has an opposite operating end 310 and a locking end 311. The operating end 310 extends out to the outer periphery of the carrying seat 20, and the locking end 311 can enter the first sub-hole 2021 and be inserted into the locking hole 210. The second limiting member 32 is at least partially disposed in the first setting hole 203, and the elastic member 33 is connected between the second limiting member 32 and the locking member 31, so that the locking member 31 always has a tendency to move towards the first sub-hole 2021. Thus, when the carrying structure 2 is in a predetermined position relative to the fixing structure 1, and the end of the fixing member 22 is correspondingly inserted into the setting groove 12, the locking member 31 can make the locking end 311 inserted into the locking hole 210 under the elastic force of the elastic member 33 and remain in the current position, so that the threaded member 21 cannot rotate relative to the carrying seat 20. Furthermore, the fixing member 22 can be more stably maintained in a state where the end is inserted into the setting groove 12.

[0049] When it is necessary to adjust the relative position of the bearing structure 2 and the fixed structure 1, the operator can pull up the operating end 310 to move the locking piece 31 as a whole in a direction away from the first sub-hole 2021 so that the locking end 311 is disengaged from the locking hole 210, and then the threaded member 21 can be rotated to disengage the fixing member 22 from the setting groove 12, and then the bearing structure 2 is moved to a predetermined position relative to the fixed structure 1, and then the threaded member 21 is rotated to make the fixing member 22 inserted into the corresponding setting groove 12, and finally the operator releases the operating end 310, so that the locking piece 31 moves toward the first sub-hole 2021 under the action of the elastic force of the elastic member 33 until the locking end 311 is inserted into the locking hole 210.

[0050] In order to facilitate the operator to operate the operating end 310, optionally, the operating end 310 may be provided with, including but not limited to, an operating ring and an operating handle.

[0051] Optionally, the second limiting member 32 may be a structure including but not limited to a cylindrical, annular, or block-shaped structure, wherein when the first limiting member 23 includes a cylindrical or annular structure, the first limiting member 23 may be sleeved on the outer periphery of the threaded member 21, and the limiting effect of the first limiting member 23 on the threaded member 21 is more balanced.

[0052] Exemplarily, the second limit member 32 can be screwed to the first setting hole 203, and the second limit member 32 can be provided with a through second setting hole 320, so that the second limit member 32 is formed into a cylindrical bolt structure with a central opening, the second setting hole 320 is connected to the first setting hole 203, and the locking member 31 can also be plugged and connected to the second setting hole 320. A protrusion is provided on the outer periphery of the locking member 31, and the protrusion is located between the second limit member 32 and the first sub-hole 2021. The elastic member 33 elastically abuts between the protrusion and the second limit member 32, so that the second limit member 32 is easy to be disassembled and assembled on the bearing seat 20, so as to facilitate the operator to disassemble and assemble the locking assembly 3 on the bearing seat 20.

[0053] like Figure 4 and Figure 5 As shown, optionally, the supporting seat 20 includes a first connecting portion 204 and a supporting portion 205 connected to each other, the first hole 201 and the second hole 202 are both provided on the first connecting portion 204, and the supporting portion 205 is located on one side of the first connecting portion 204 along the third direction S3, wherein the first direction S1 and the second direction S2 are both perpendicular to the third direction S3, so that when the supporting portion 205 carries a photoelectric switch, the photoelectric switch is located on one side of the fixed structure 1 and the first connecting portion 204 along the third direction S3, so that the photoelectric switch is not easy to interfere with the fixed structure 1.

[0054] To facilitate the disassembly and assembly of the first connecting portion 204 to the fixing structure 1, optionally, the first connecting portion 204 includes a first part 2041, a second part 2042, and a locking member 2043. The first part 2041 includes a first flat plate 2041a, a second flat plate 2041b, and a third flat plate 2041c that are sequentially connected. The first flat plate 2041a and the third flat plate 2041c are parallel to each other and spaced apart in the third direction S3. The second flat plate 2041b is perpendicular to the first flat plate 2041a and the third flat plate 2041c. The second part 2042 is disposed between the first flat plate 2041a and the third flat plate 2041c, and the second part 2042 is spaced apart from the second flat plate 2041b, so that a first hole 201 is formed among the second part 2042, the first flat plate 2041a, the second flat plate 2041b, and the third flat plate 2041c. A second hole 202 is provided in the second part 2042. The second part 2042 is locked to both the first flat plate 2041a and the third flat plate 2041c through the locking member 2043. Thus, by unlocking the locking member 2043, an operator can separate the first part 2041 from the second part 2042, thereby removing the first connecting portion 204 from the fixing structure 1. During installation, the first part 2041 and the second part 2042 can be respectively installed on the fixing structure 1 from two opposite sides in the second direction S2 of the fixing structure 1, and the first part 2041 and the second part 2042 are locked and connected into one body through the locking member 2043, so that the first connecting portion 204 can be installed on the fixing structure 1.

[0055] Exemplarily, two opposite sides of the second part 2042 facing the first flat plate 2041a and the third flat plate 2041c may be provided with screw holes. The first flat plate 2041a and the third flat plate 2041c may respectively be provided with through holes corresponding to the corresponding screw holes. The locking member 2043 may include a bolt or a screw. The locking member 2043 may partially pass through the through hole and be screwed into the screw hole to lock the first flat plate 2041a or the third flat plate 2041c to the second part 2042.

[0056] As Figure 2 And Figure 6 As shown, optionally, the fixing base 10 includes a second connecting portion 101 and two third connecting portions 102. A rib 11 is provided on the second connecting portion 101. The two third connecting portions 102 are respectively connected to two opposite ends of the second connecting portion 101 in the first direction S1. The third connecting portion 102 is used to connect to an externally provided structure. By connecting the third connecting portions 102 to both opposite ends of the second connecting portion 101 in the first direction S1, when the fixing base 10 is disposed on the externally provided structure, the supporting effect of the externally provided structure on the entire fixing base 10 is more balanced, stable, and reasonable.

[0057] Exemplarily, through holes may be provided on the third connecting portion 102 for screws or bolts to pass through and connect the third connecting portion 102 to an externally arranged structure.

[0058] In other embodiments, the third connecting portion 102 may also be connected to an externally arranged structure by means including but not limited to snap connection, magnetic attraction connection, etc.

[0059] As Figure 6 shown, optionally, the second connecting portion 101 includes a first side 1011 and a second side 1012 that are opposite to each other in the second direction S2. The rib 11 is provided on the first side 1011. In the second direction S2, the protruding height of the bearing seat 20 from the second side 1012 is h1, and the protruding height of the third connecting portion 102 from the second side 1012 is h2, where h1 < h2. When the third connecting portion 102 is connected to an externally arranged structure, it can make the second side 1012 spaced from the externally arranged structure and also make the bearing seat 20 spaced from the externally arranged structure, avoiding interference between the bearing seat 20 and the second side 1012 and the externally arranged structure.

[0060] Please refer to again Figure 4 , optionally, a bearing hole 2051 may be provided on the bearing portion 205, and the photoelectric switch may be inserted into the bearing hole 2051 to be connected to the bearing portion 205.

[0061] Optionally, an elastic pressing member (not shown in the figure) may be provided on the hole wall of the bearing hole 2051. The elastic pressing member is used to press against the outer periphery of the photoelectric switch to further fix the photoelectric switch and improve the bearing stability of the bearing portion 205 for the photoelectric switch.

[0062] Optionally, a threaded hole (not shown in the figure) may be provided on the outer side surface of the bearing portion 205.
