Description

Technical Field

[0001] The utility model relates to the technical field of low-frequency magnetic field transmitting devices, in particular to an adjustable bracket for low-frequency magnetic field transmitting devices. Background Art

[0002] A low-frequency magnetic field transmitter is a device that can generate a specific low-frequency magnetic field. It usually uses the principle of electromagnetic induction to generate a magnetic field by flowing current in a conductor. Specifically, when a current of a certain frequency and magnitude passes through a conductor such as a coil, a low-frequency magnetic field of the corresponding frequency will be generated in the surrounding space. By adjusting the magnitude, frequency and direction of the current, the intensity, frequency and direction of the generated magnetic field can be controlled.

[0003] The adjustable bracket of existing low-frequency magnetic field transmitting devices often adjusts the angle in a single direction. Adjustment in one direction limits the flexibility and adaptability of the device to a certain extent, and is not convenient for meeting the multi-dimensional requirements of the magnetic field emission angle in different application scenarios. The bracket that can only be adjusted in one direction cannot achieve multi-angle adjustment, which may affect the accuracy and comprehensiveness of the magnetic field emitted by the transmitting device.

DETAILED DESCRIPTION

[0021] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-5 The utility model provides a technical solution: it includes a base 1 and a fixing base 11 connected to the base 1 for installing a low-frequency magnetic field transmitting device, the base 1 is connected to two mounting plates 5 symmetrical to each other with the vertical axis of the base 1 as the center, a worm 6 is mounted between the two mounting plates 5 for relative rotation, a worm wheel 8 is meshed and connected above the worm 6, a third rotating shaft 9 is inserted at the axis of the worm wheel 8, a second adjusting frame 10 is fixedly connected to both ends of the third rotating shaft 9, and the top of the second adjusting frame 10 is fixedly connected to the fixing base 11, wherein,

[0023] The base 1 is provided with two sets of driving components that can respectively drive the fixed seat 11 to rotate parallel to the axis of the worm 6 and perpendicular to the axis of the worm 6. The driving component includes a first rotating shaft 3 and a second gear 7. The first rotating shaft 3 that drives the fixed seat 11 to rotate parallel to the axis of the worm 6 is fixedly connected to the worm 6.

[0024] During specific implementation, a low-frequency magnetic field transmitting device is placed on the top of the fixed seat 11. When the first rotating shaft 3 that drives the fixed seat 11 to rotate parallel to the axis of the worm 6 rotates, the first rotating shaft 3 fixedly connected to the worm 6 rotates, and the worm wheel 8 above the worm 6 engages with the worm 6 to move synchronously. When the worm wheel 8 rotates, it drives the third rotating shaft 9 to rotate synchronously, so that the second adjustment frame 10 rotates with the third rotating shaft 9, and the angle of the low-frequency magnetic field transmitting device is adjusted laterally with the worm wheel 8.

[0025] See Figure 1 The outside of the worm gear 8 is sleeved with a first adjusting frame 4, the bottom of the first adjusting frame 4 is rotatably connected to the mounting plate 5, and one side of the bottom of the first adjusting frame 4 is fixedly connected to the first rotating shaft 3 that drives the fixed seat 11 to rotate perpendicular to the axis direction of the worm 6.

[0026] By fixing one side of the bottom of the first adjustment frame 4 to the first rotating shaft 3 that drives the fixed seat 11 to rotate parallel to the axis of the worm 6, when the first rotating shaft 3 is driven to rotate, the first adjustment frame 4 rotates synchronously with the first rotating shaft 3, and the fixed seat 11 rotates perpendicular to the axis of the worm 6, thereby adjusting the longitudinal angle of the low-frequency magnetic field emission device on the top of the first adjustment frame 4.

[0027] See Figure 1 and Figure 5 The driving assembly also includes a first gear 2, which is meshed with the second gear 7. A second rotating shaft 15 is inserted into the first gear 2, and a third gear 19 is fixedly connected to the coaxial side of the first gear 2.

[0028] By setting the first gear 2 and the second gear 7, the diameter of the first gear 2 is smaller than the diameter of the second gear 7. When the staff makes a preliminary angle confirmation of the device, they can directly manually rotate the second gear 7 to adjust the angle of the low-frequency magnetic field emission device to a large extent, thereby improving work efficiency. When further fine adjustment is required, the first gear 2 is rotated through the second rotating shaft 15 to adjust the angle of the low-frequency magnetic field emission device to a smaller extent.

[0029] See Figure 1 and Figure 5 A pawl 20 is clamped on one side of the third gear 19, and a telescopic spring 21 is fixedly connected to one side of the pawl 20. A mounting block is provided on the base 1, and one end of the telescopic spring 21 is fixedly connected to the mounting block.

[0030] By providing the telescopic spring 21, the pawl 20 is pressed vertically downward by the restoring force of the telescopic spring 21 after the angle is adjusted, and engages the third gear 19, thereby improving the positioning stability of the device after the angle is confirmed.

[0031] See Figure 2 and Figure 3 A mounting groove 17 is provided on the top of the fixing seat 11, and a slider 16 is slidably connected in the mounting groove 17. A rectangular block 14 is fixedly installed on the top of the slider 16, and a fixing plate 13 is fixedly installed on one side of the rectangular block 14.

[0032] By providing two fixing plates 13 , the low-frequency magnetic field transmitting device is placed between the fixing plates 13 , so that the two fixing plates 13 can clamp, fix or remove the low-frequency magnetic field transmitting device.

[0033] See Figure 3 and Figure 4 A threaded rod 12 is rotatably provided in the fixing seat 11 , and the number of the sliders 16 is set to two, and the two sliders 16 are symmetrically arranged on both sides of the mounting groove 17 , and the sliders 16 are threadedly connected to the threaded rod 12 .

[0034] By providing a bidirectional thread on the threaded rod 12, it is convenient for the staff to take and place the low-frequency magnetic field transmitting device. By rotating the threaded rod 12, the two sliders 16 on the threaded rod 12 are relatively close to or away from each other on the threaded rod 12, and the fixing plate 13 is close to or away from the low-frequency magnetic field transmitting device, thereby clamping, fixing or removing the low-frequency magnetic field transmitting device.

[0035] See Figure 2 One end of the threaded rod 12 is fixedly connected to a turntable, and the diameter of the turntable is slightly larger than the diameter of the threaded rod 12.

[0036] By providing a turntable, it is convenient for the staff to hold the turntable and rotate the threaded rod 12, thereby improving the convenience of rotation for the staff.

[0037] See Figure 1 and Figure 5 A mounting shell 18 is fixedly mounted on one side of the base 1 close to the second rotating shaft 15 , and the mounting shell 18 is sleeved on the outside of the third gear 19 .

[0038] The installation shell 18 is provided to protect the third gear 19 and the pawl 20 and ensure their stability after being engaged.

[0039] Working Principle: When the staff needs to adjust the angle of the low-frequency magnetic field transmitter, they can change the horizontal and vertical angles of the transmitter by adjusting the bracket. Rotate the second rotating shaft 15 on one side to rotate the first gear 2, which drives the second gear 7 meshing with it to rotate, causing the first rotating shaft 3 fixedly connected to the first adjustment frame 4 to rotate along with the second gear 7. By moving the first adjustment frame 4 in the longitudinal direction, the longitudinal angle of the low-frequency magnetic field transmitter on the top of the first adjustment frame 4 is adjusted.

[0040] When the first rotating shaft 3 fixedly connected to the worm 6 is rotated, the worm wheel 8 above the worm 6 engages with the worm 6 and moves synchronously. When the worm wheel 8 rotates, it drives the third rotating shaft 9 to rotate synchronously, causing the second adjustment frame 10 to rotate along with the third rotating shaft 9. The angle of the low-frequency magnetic field transmitting device is adjusted laterally along with the worm wheel 8.

[0041] When the staff makes a preliminary angle confirmation of the device, they can manually rotate the second gear 7 to adjust the angle of the low-frequency magnetic field transmitting device to a greater extent, thereby improving work efficiency. The diameter of the first gear 2 is smaller than that of the second gear 7. When further fine adjustment is required, the first gear 2 is rotated through the second rotating shaft 15 to adjust the angle of the low-frequency magnetic field transmitting device to a smaller extent.

[0042] When the staff takes or places the low-frequency magnetic field transmitting device, they can rotate the threaded rod 12 to make the two sliders 16 on the threaded rod 12 relatively close to or away from each other on the threaded rod 12, so as to make the fixing plate 13 close to or away from the low-frequency magnetic field transmitting device, thereby clamping, fixing or removing the low-frequency magnetic field transmitting device.
