Description

Technical Field

[0001] The invention relates to a photoelectric switch bracket. Background Art

[0002] Photoelectric switch is a device that detects objects by blocking or reflecting the light beam of the detected object and connecting the circuit through the synchronization circuit. In order to facilitate the use of photoelectric switches, it is necessary to use a photoelectric switch bracket to install the photoelectric switch. Since photoelectric switches need to be used in various working conditions during industrial use, it is always necessary to adjust the position and / or angle of the photoelectric switch to match the position of the detected object.

[0003] For this problem, the Chinese utility model patent "Photoelectric switch bracket" with the publication number CN209943843U discloses a mounting bracket, which includes a fixed block that can be moved up and down on the column, and also includes a mounting plate for mounting the photoelectric switch, the mounting plate protrudes toward one side of the fixed block to form a ball head, so as to form a concave cavity on the side facing away from the fixed block; the surface of the fixed block is provided with a ball socket matching the ball head, and the ball head can be rotatably connected to the ball socket through a connecting assembly. This utility model can only solve the problem of angle adjustment, and in the initial installation process, in order to make the light beam of the photoelectric switch smoothly irradiate the synchronous circuit to the circuit connection position, it is necessary to constantly adjust, and the difficulty of adjustment increases according to the distance between the two. In this way, when the distance between the two is far, it is very difficult to adjust, and the photoelectric switch will deviate if it moves or swings slightly. At the same time, if the position of the photoelectric switch is operated by multiple knobs, the operation is very cumbersome, and it is impossible to provide a bracket that can be fine-tuned and operated after the photoelectric switch is installed in the approximate position, which greatly increases the difficulty of installation.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] See also Figure 1-11 , the present invention provides a technical solution:

[0038] A photoelectric switch with multi-angle change and convenient installation, comprising a fixed structure 1, a rotating mechanism 2 and two auxiliary rotor mechanisms 3 are arranged on the fixed structure 1, a forward driving mechanism 4 and a reverse driving mechanism 5 are respectively connected between the rotating mechanism 2 and the two auxiliary rotor mechanisms 3, a lateral moving mechanism 6 is arranged on the fixed structure 1, a vertical moving mechanism 7 is arranged on the lateral moving mechanism 6, a first linkage mechanism 8 is arranged between one auxiliary rotor mechanism 3 and the lateral moving mechanism 6, a second linkage mechanism 9 is arranged between the other auxiliary rotor mechanism 3 and the vertical moving mechanism 7, a universal articulated ball structure 10 is arranged on the vertical moving mechanism 7, and a photoelectric switch 11 is arranged on the universal articulated ball structure 10;

[0039] The above structural principle:

[0040] During operation, the photoelectric switch 11 is installed to the approximate position of the synchronous circuit, and the fixed structure 1 fixes the photoelectric switch 11. The fixed structure 1 is installed in the approximate position. At this time, if the angle position needs to be adjusted, it is adjusted by swinging the universal articulated ball structure 10, and it swings at multiple angles with strong adaptability. When the position is offset, if the horizontal and vertical positions need to be adjusted, the rotating mechanism 2 is twisted. During the rotation of the rotating mechanism 2, the forward drive mechanism 4 or the reverse drive mechanism 5 is driven to operate. When the rotating mechanism 2 rotates forward, the forward drive mechanism 4 is triggered to rotate. At this time, the forward drive mechanism 4 drives one of the auxiliary rotor mechanisms 3 on one side to rotate, so as to adjust one of the horizontal or vertical positions. When the rotating mechanism 2 reverses, the reverse drive mechanism 5 is triggered to rotate. At this time, the reverse drive mechanism 5 drives an auxiliary rotor mechanism 3 on the other side to rotate, so as to adjust another horizontal or vertical position, which reduces the complexity of the operation and can fine-tune the position.

[0041] The two auxiliary rotor mechanisms 3 of the present invention include two rotating shaft seats 301 arranged in the fixed structure 1, and two rotating shafts 302 are rotatably arranged on each of the two rotating shaft seats 301;

[0042] A specific structure of an auxiliary rotor mechanism 3 is provided, wherein a rotating shaft seat 301 is longitudinally fixedly arranged, and two rotating shafts 302 are also longitudinally arranged.

[0043] The rotating mechanism 2 of the present invention is arranged between two auxiliary rotor mechanisms 3, and the rotating mechanism 2 includes a central axis seat 201 arranged between two rotating axis seats 301, and a central rotating shaft 202 is rotatably arranged in the central axis seat 201;

[0044] A specific structure of a rotating mechanism 2 is provided, wherein a central axis seat 201 is longitudinally arranged, and a central rotating shaft 202 is longitudinally rotatably arranged in the central axis seat 201 .

[0045] The forward driving mechanism 4 of the present invention comprises a forward driving gear 401 arranged at one end of the rotating shaft 202, wherein a forward driven gear 402 is arranged at one end of one rotating shaft 302, the forward driving gear 401 and the forward driven gear 402 are meshed and driven, and the forward driving gear 401 is used to drive the forward driven gear 402 to rotate during the forward rotation of the rotating shaft 202;

[0046] The reverse driving mechanism 5 includes a reverse driving gear 501 arranged at the other end of the rotating shaft 202, and a reverse driven gear 502 is arranged at the other end of the rotating shaft 302. The reverse driving gear 501 and the reverse driven gear 502 are meshed and transmitted. The reverse driving gear 501 is used to drive the reverse driven gear 502 to rotate during the reverse rotation of the rotating shaft 202.

[0047] The above two driving mechanisms are triggered when the rotating shaft 202 rotates forward or reversely, respectively. When the rotating shaft 202 rotates forward, it drives the rotating shaft 302 on one side to rotate, and when the rotating shaft 202 rotates reversely, it drives the rotating shaft 302 on the other side to rotate.

[0048] The forward driving gear 401 of the present invention comprises a first rotating disk 4011 arranged at one end of the central rotating shaft 202, a plurality of first elastically retractable teeth 4012 are uniformly distributed on the circumferential outer wall of the first rotating disk 4011, a first guiding inclined surface 4013 is respectively arranged at the same side corner of the plurality of first elastically retractable teeth 4012, and a first auxiliary fillet 4014 is arranged at one side corner of the teeth of the forward driven gear 402;

[0049] The reverse driving gear 501 includes a second rotating disk 5011 arranged at the other end of the rotating shaft 202, and a plurality of second elastic telescopic teeth 5012 are uniformly distributed on the circumferential outer wall of the second rotating disk 5011, and a second guide surface 5013 is respectively arranged at the same side corner of the plurality of second elastic telescopic teeth 5012, and a second auxiliary fillet 5014 is arranged at a side corner of the teeth of the reverse driven gear 502, and the second guide surface 5013 and the first guide inclined surface 4013 are arranged at opposite positions, and the first auxiliary fillet 4014 and the second auxiliary fillet 5014 are arranged at opposite positions;

[0050] The above provides the specific structures of the forward drive gear 401 and the reverse drive gear 501. The positions between them and the internal structures are just opposite to each other.

[0051] In order to realize one-way drive, during the rotation of the rotating disk, the elastic telescopic teeth and the passive gear are meshed for transmission. Since the elastic telescopic teeth are provided and the passive gear is provided with an auxiliary fillet, since one side of the auxiliary fillet is provided on one side of the passive gear, and the guide surface on the elastic telescopic teeth is provided on the side opposite to the auxiliary fillet, when the rotating disk rotates in one direction, the auxiliary fillet and the guide surface cooperate to compress the elastic telescopic teeth to realize idling. When the rotating disk rotates in the other direction, the opposite is true and the gear operates normally.

[0052] The lateral movement mechanism 6 of the present invention includes a lateral movement track 601 arranged on the fixed structure 1, and a lateral movement block 602 is slidably arranged on the lateral movement track 601, providing a lateral movement structure.

[0053] The vertical moving mechanism 7 of the present invention comprises a vertical moving track 701 arranged on the horizontal moving block 602, and a vertical moving block 702 is slidably arranged on the vertical moving track 701, providing a vertical moving structure.

[0054] The first linkage mechanism 8 of the present invention includes a first rotating disk 801 arranged on the end surface of one of the auxiliary rotor mechanisms 3, a first eccentric shaft 802 arranged on the end surface of the first rotating disk 801, a first hinge shaft 803 is arranged on the lateral moving block 602, and a first connecting rod 804 is hinged between the first eccentric shaft 802 and the first hinge shaft 803;

[0055] According to the above structural principle, when the first turntable 801 rotates, the first eccentric shaft 802 rotates eccentrically around the center of the first turntable 801. At this time, since the first eccentric shaft 802 and the first hinge shaft 803 are driven by the hinged first connecting rod 804, during the rotation of the first eccentric shaft 802, the first connecting rod 804 drives the first eccentric shaft 802 to move laterally according to the different positions of the first eccentric shaft 802, thereby driving the lateral moving block 602 to move left and right. Since the rotating mechanism 2 needs to realize the movement of the four position directions of the photoelectric switch 11 (respectively up, down, left and right directions), the above structure is used to realize the left and right reciprocating motion. That is to say, by continuously driving the rotating mechanism 2 to rotate, the first turntable 801 is rotated cyclically. At this time, the reciprocating movement of the lateral moving block 602 is realized by the first connecting rod 804.

[0056] The second linkage mechanism 9 of the present invention includes a second rotating disk 901 arranged on the end face of another auxiliary rotor mechanism 3, a second eccentric shaft 902 arranged on the end face of the second rotating disk 901, an auxiliary vertical track 903 arranged parallel to the vertical moving track 701 is arranged on the fixed structure 1, an auxiliary slider 904 is slidably arranged in the auxiliary vertical track 903, a transverse sleeve 905 is arranged on the vertical moving block 702, a transverse driving shaft 906 for driving the transverse sleeve 905 to move up and down is arranged on the auxiliary slider 904, the driving transverse sleeve 905 is sleeved in the transverse driving shaft 906 for left and right movement, a second hinge shaft 907 is arranged on the auxiliary slider 904, and a second connecting rod 908 is hinged between the second eccentric shaft 902 and the second hinge shaft 907;

[0057] The principle of the above reciprocating motion structure is the same as the movement of the first linkage mechanism 8. In order to ensure that the vertical moving block 702 can be driven up and down at different lateral positions, the lateral sleeve 905 and the lateral drive shaft 906 are matched so that the lateral sleeve 905 can be adjusted to the left and right position outside the lateral drive shaft 906. At the same time, when the auxiliary slider 904 can move up and down, the lateral sleeve 905 can also be moved up and down regardless of any lateral position within the range.

[0058] An anti-rotation mechanism 12 for preventing the rotating mechanism 2 from rotating is provided between the rotating mechanism 2 and the fixed structure 1 of the present invention to prevent the position from automatically changing when no one is operating, thereby ensuring the stability of the bracket.

[0059] The anti-self-rotation mechanism 12 of the present invention includes a torsion sleeve 121 sleeved on the rotation input shaft end of the rotating mechanism 2, the inner wall of the torsion sleeve 121 is provided with a driving strip 122 along the axial direction of the torsion sleeve 121, the rotation output shaft end of the rotating mechanism 2 is provided with a driving groove 123, the driving strip 122 is movably arranged in the driving groove 123, the end surface of the torsion sleeve 121 close to the fixed structure 1 is provided with a first annular anti-sliding block 124, the surface of the fixed structure 1 outside the circumference of the rotating mechanism 2 is provided with a second annular anti-sliding block 125 for cooperating with the first annular anti-sliding block 124 to limit the rotation of the rotating mechanism 2, and the torsion sleeve 121 and the rotating mechanism 2 are provided with an elastic structure 126 for keeping the surface of the first annular anti-sliding block 124 in contact with the surface of the second annular anti-sliding block 125;

[0060] According to the above structural principle, the cooperation between the driving groove 123 and the driving bar 122 ensures that the rotation of the torsion sleeve 121 can drive the rotation input end of the rotating mechanism 2 to rotate. Due to the elastic structure 126, the first annular anti-slip block 124 and the second annular anti-slip block 125 are in a fitted state in a normal state, ensuring that the torsion sleeve 121 is locked. If adjustment is required, the torsion sleeve 121 is manually pulled out and rotated for adjustment.

[0061] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected.
