Description

Technical Field

[0001] The utility model relates to a DC radiation ring axis positioning device, belonging to the technical field of electronic detection equipment. Background Art

[0002] When testing electronic equipment in motor vehicles, DC radiation rings and Hall antennas are required. The DC radiation ring used by our company is cylindrical, with coaxial circular racks at the front and rear ends, and a coiled coil between the front and rear circular racks. The Hall antenna used by our company is a handheld strip, with the front end as the receiving end of the antenna and the back end connected to the wire. When using it, the receiving end of the front end of the Hall antenna needs to be placed on the axis of the DC radiation ring.

[0003] The traditional way of using it is to hold the Hall antenna and visually place the receiving endpoint of the front end on the axis of the DC radiation ring. Due to hand shaking or visual differences, it is always difficult to align and stably place the receiving endpoint of the Hall antenna on the axis of the DC radiation ring, so the measured detection data always fluctuates greatly. To address this problem, it was thought of placing the DC radiation ring in a rectangular frame, setting intersecting diagonal lines at the front end of the rectangular frame, and the intersection is located on the axis of the DC radiation ring. When using it, the receiving endpoint of the Hall antenna is placed at the intersection for axis alignment, but it still cannot be stably maintained in this position due to hand shaking, and when the receiving endpoint is moved back and forth as needed, it is still easy to deviate from the axis, making it difficult to obtain accurate detection results. Utility Model Content

[0004] The technical problem to be solved by the utility model is: how to stably place the receiving end point of the Hall antenna on the axis of the DC radiation ring and enable it to move back and forth on the axis as required.

The sliding sleeve is sleeved on the sliding beam and can slide along the sliding beam. The placement plate is installed on the sliding sleeve.

[0009] The lifting mechanism comprises two guide columns, and the sliding beam is correspondingly provided with two vertically penetrating sliding holes. The sliding beam is respectively sleeved on the two guide columns through the two sliding holes and can slide up and down along the guide columns.

[0010] A positioning bolt which can be radially screwed into the sliding hole and pressed against the guide column is arranged on the sliding beam.

[0011] The lifting mechanism also includes a threaded column with external threads on the outer circumference, and a vertically penetrating threaded hole with internal threads is provided between the two sliding holes of the sliding beam.

[0023] The utility model is further described below in conjunction with the accompanying drawings: Embodiment 1

[0024] like Figure 1 , 2 As shown, a DC radiation ring axis positioning device comprises a base plate 1, a support seat 2 arranged on the base plate 1 for horizontally placing a DC radiation ring 4, a placement frame 3 arranged on the left or right side of the support seat 2 for placing a Hall antenna 5, the placement frame 3 having a lifting mechanism and an axial sliding mechanism installed on the lifting mechanism, and a placement plate 301 for placing the Hall antenna 5, the placement plate 301 being arranged on the axial sliding mechanism, capable of being lifted and lowered together with the axial sliding mechanism, and capable of sliding forward and backward on the axial sliding mechanism in the direction of the DC radiation ring axis. Before use, the Hall antenna 5 is placed on the placement plate 301, and the receiving end point 501 at the front end of the Hall antenna 5 is adjusted to the same height as the axis 401 of the DC radiation ring 4 by the lifting mechanism, and then the Hall antenna 5 is moved left and right so that its receiving end point 501 is located on the axis 401 of the DC radiation ring 4. In this way, there is no need to temporarily find the position where the receiving end point 501 should be and maintain it by hand each time it is used. When the position of the receiving end point 501 on the axis 401 needs to be adjusted, the placement plate 301 only needs to be slid forward and backward by the axial sliding mechanism. When DC radiation rings 4 of different specifications are used, they can be adjusted by the lifting mechanism.

[0025] The left and right sides of the support base 2 are respectively provided with a left bevel side wall 2011 and a right bevel side wall 2012, which are arranged in a V-shape to form a V-shaped groove 201, and the DC radiation ring 4 is placed in the V-shaped groove 201, and the DC radiation ring 4 is supported by the left bevel side wall 2011 and the right bevel side wall 2012. In this way, when DC radiation rings 4 of different diameters are used, it can be ensured that their axes 401 are all located on the same vertical plane.

[0026] The axial sliding mechanism includes a sliding beam 302 with a rectangular cross section and a sliding sleeve 303 whose inner wall surface matches the outer peripheral surface of the sliding beam 302. The sliding sleeve 303 is sleeved on the sliding beam 302 and can slide along the sliding beam 302. The placement plate 301 is installed on the sliding sleeve 303. The sliding beam 302 with a rectangular cross section can prevent the sliding sleeve 303 with a matching inner wall surface from rotating around the sliding beam 302, thereby ensuring that the placement plate will not deflect.

[0027] The lifting mechanism includes two guide columns 304, and two vertically penetrating sliding holes are correspondingly provided on the sliding beam 302. The sliding beam 302 is respectively mounted on the two guide columns 304 through the two sliding holes and can slide up and down along the guide columns 304. The two guide columns can ensure that the sliding beam 302 will not rotate around one of them.

[0028] A positioning bolt 306 is provided on the sliding beam 302 and can be radially screwed into the sliding hole to press against the guide column 304, so as to fix the sliding beam 302 at a set height.

[0029] The upper surface of the placement plate 301 has a placement groove 3011 facing the axis direction of the DC radiation ring. The Hall antenna 5 is placed in the placement groove 3011 and can move left and right in the placement groove 3011.

[0030] All parts of this device are made of polymer materials to avoid interference of metal materials to electromagnetic waves. Embodiment 2

[0031] like Figure 3 As shown, the difference from the first embodiment is that the lifting mechanism further includes a threaded column 305 with an outer thread 3051 on the outer circumference, and a threaded hole with an inner thread is provided between the two sliding holes of the sliding beam, and the threaded column 305 is screwed into the threaded hole provided on the sliding beam 302 to the lower end to be supported on the base plate 1. In this way, when adjusting the height, only the threaded column 305 needs to be rotated, and the height positioning can be achieved, which is more convenient to use. Embodiment 3

[0032] like Figure 4 As shown, the difference from the second embodiment is that a counterweight block 307 is provided at the rear end of the sliding beam 302 so that the weights of the front and rear ends of the sliding beam 302 are the same or close, which can ensure the smooth lifting of the sliding beam 302.

[0033] The above embodiments are only used to more clearly describe the present invention and cannot be regarded as limiting the protection scope of the present invention. Any modifications in equivalent forms should be regarded as falling within the protection scope of the present invention.
