[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 As shown, this utility model discloses a wireless limit switch with adjustable detection distance, comprising a switch body 1. A rectangular ring 2 is attached to the surface of the switch body 1. Limiting rings 3 are attached to both the left and right sides of the rectangular ring 2. The inner wall of the limiting rings 3 is fixedly connected to the surface of the switch body 1. Adjusting brackets 4 are fixedly connected to the upper surface of the rectangular ring 2 and the upper surface of the switch body 1. A guide block 5 is fixedly connected to the back of the switch body 1. A trapezoidal groove 6 is opened on the back of the guide block 5. A trapezoidal column 7 is attached to the inner wall of the trapezoidal groove 6. A mounting plate 8 is fixedly connected to the back of the trapezoidal column 7. A locking groove 9 is opened on the front of the trapezoidal column 7. A locking block 10 is fixedly connected to the back of the rectangular ring 2. The surface of the locking block 10 is attached to the inner wall of the locking groove 9.

[0029] The switch body 1 includes a housing 101, a triggering mechanism 102, a signal detection module 103, a wireless transmission module 104, a power supply module 105, and a control module 106. The left side of the housing 101 is fixedly connected to the right side of the triggering mechanism 102. The surfaces of the signal detection module 103, the wireless transmission module 104, the power supply module 105, and the control module 106 are all fixedly connected to the inner wall of the housing 101. The inner wall of the rectangular ring 2 is attached to the surface of the housing 101. The inner wall of the limiting ring 3 is fixedly connected to the surface of the housing 101. The bottom of the adjusting bracket 4 is fixedly connected to the upper surface of the housing 101. The front of the guide block 5 is fixedly connected to the back of the housing 101.

[0030] The positive and negative terminals of the output terminal of the power supply module 105 are connected to the power interfaces of the control module 106, the signal detection module 103, and the wireless transmission module 104, respectively. The output terminal of the trigger mechanism 102 is electrically connected to the input terminal of the signal detection module 103. The signal output terminal of the signal detection module 103 is amplified and filtered before being connected to the I / O interface or ADC interface of the control module 106. The UART, SPI, or I2C interface of the control module 106 is connected to the corresponding interface of the wireless transmission module 104.

[0031] The adjusting bracket 4 includes a connecting plate 401, a threaded cylinder 402, a bolt 403, a bearing 404, and a connecting block 405. The bottom of the connecting plate 401 is fixedly connected to the upper surface of the rectangular ring 2. The inner wall of the connecting plate 401 is fixedly connected to the surface of the threaded cylinder 402. The inner wall of the threaded cylinder 402 is threadedly connected to the surface of the bolt 403. The surface of the bolt 403 is fixedly connected to the inner ring of the bearing 404. The outer ring of the bearing 404 is fixedly connected to the inner wall of the connecting block 405. The bottom of the connecting block 405 is fixedly connected to the upper surface of the housing 101.

[0032] It should be noted that the limiting ring 3 allows the rectangular ring 2 to move only up and down on the housing 101. When the bolt 403 on the adjusting bracket 4 is rotated, the connecting plate 401 can be moved up or down through the cooperation of the bolt 403 and the threaded cylinder 402. Through the connecting plate 401 and the rectangular ring 2, the locking block 10 can be inserted into the locking groove 9 or separated from the locking groove 9.

[0033] The trapezoidal slot 6 and trapezoidal column 7 work together to allow the housing 101 to move only left and right. When the locking block 10 is inserted into the locking slot 9, the position of the housing 101 on the mounting plate 8 cannot be changed due to the cooperation between the locking block 10 and the locking slot 9. When the locking block 10 is separated from the locking slot 9, the housing 101 can move freely left and right. At this time, the position of the housing 101 on the mounting plate 8 can be changed. Meanwhile, the trapezoidal column 7 is provided with multiple locking slots 9. When the housing 101 moves to the designated position, the housing 101 can be fixed at the designated position by inserting the locking block 10 into the corresponding locking slot 9. Thus, the position of the housing 101 on the mounting plate 8 can be adjusted according to different detection requirements, and the detection distance of the wireless limit switch can be changed by adjusting the position of the housing 101 on the mounting plate 8.

[0034] A vertical plate 11 is fixedly connected to the right side of the housing 101. A circular hole 12 is opened inside the vertical plate 11. A cylinder 13 is fixedly connected to the inner wall of the circular hole 12. A retaining ring 14 is fixedly connected to the inner wall of the cylinder 13. A spring 15 is fixedly connected to the back of the retaining ring 14. A steel ball 16 is fixedly connected to the back of the spring 15. A rectangular plate 17 is fixedly connected to the front of the mounting plate 8. An arc groove 18 is opened on the front of the rectangular plate 17. The inner wall of the arc groove 18 is in contact with the surface of the steel ball 16.

[0035] The number of arc-shaped grooves 18 is equal to the number of locking grooves 9, and the distance between two adjacent arc-shaped grooves 18 is equal to the distance between two adjacent locking grooves 9. The diameter of the arc-shaped groove 18 is equal to the diameter of the steel ball 16, and the depth of the arc-shaped groove 18 is less than the radius of the steel ball 16.

[0036] It should be noted that when the locking block 10 is aligned with the locking groove 9, the steel ball 16 fits against the inner wall of the arc groove 18, and the pushing force of the spring 15 on the steel ball 16 increases the resistance when the switch body 1 moves. Thus, when the user moves the switch body 1, he / she can intuitively judge whether the locking block 10 is aligned with the locking groove 9 by the magnitude of the resistance when moving, so that the user can quickly align the locking block 10 with the locking groove 9.

[0037] The working principle of this utility model is as follows: First, the mounting plate 8 on the wireless limit switch is installed on the mounting bracket. Then, when the controlled object moves to the set position, the controlled object touches the trigger mechanism 102, causing the trigger mechanism 102 to move. After the signal detection module 103 senses the trigger action, it converts the physical displacement into an electrical signal. The control module 106 reads the electrical signal output by the signal detection module 103 through the interface, decodes the signal, performs logical judgment, and identifies whether the object has reached the target position. After encoding the judgment result, the control module 106 sends it to the wireless transmission module 104 through the communication interface, which then sends the signal to the receiving end wirelessly (Bluetooth, WiFi, etc.). At the same time, it can receive the feedback signal from the receiving end to complete the two-way detection and confirmation.

[0038] When the detection distance needs to be adjusted, first rotate the bolt 403 to move the locking block 10 upwards in the cooperation of the bolt 403 and the threaded cylinder 402. After the locking block 10 separates from the locking groove 9, push and pull the housing 101 to change the position of the switch body 1 on the mounting plate 8. After the housing 101 moves to the appropriate position, rotate the bolt 403 to move the locking block 10 downwards in the cooperation of the bolt 403 and the threaded cylinder 402, and insert the locking block 10 into the corresponding locking groove 9. At this time, the housing 101 can be fixed in the designated position by the cooperation of the locking block 10 and the locking groove 9. By adjusting the position of the housing 101 on the mounting plate 8, the detection distance of the wireless limit switch can be changed.

[0039] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
