Description

Technical Field

[0001] The utility model relates to the technical field of Hall sensors, in particular to a micro-displacement high-precision measurement rebound Hall sensor. Background Technique

[0002] A Hall sensor is a magnetic field sensor made according to the Hall effect. The current Hall sensors include a coil and a Hall element clamped on the coil; when using the Hall sensor for current testing, first pass a cable through the center of the coil, and then apply a target current to the cable through an external power supply. When the current in the cable passes through the coil, the Hall element generates a potential difference, and the coil generates a magnetic field. Under the action of the magnetic field, an output signal is formed. When the magnetic field generated by the coil is the same as the magnetic field generated by the energized cable, the detection is completed by detecting the output current. However, during the use of the Hall sensor, displacement may occur, resulting in magnetic field changes.

[0003] Chinese Patent No. CN209878858U discloses a Hall sensor, which includes a base and an induction ring detachably connected to the base. The base is in a U shape with an opening facing the induction ring, and an induction coil is arranged inside the induction ring; a plug-in block is arranged on the outer circumferential surface of the induction ring; the base is provided with a plug-in hole for cooperating with the plug-in block; connecting holes are opened on the opposite side walls of the plug-in hole, and action rods are arranged in the connecting holes. Through holes are formed in the plug-in block for cooperating with the action rods; one end of the action rod away from the plug-in hole abuts against a plug rod vertically inserted on the base, and a first spring is sleeved on the end of the action rod away from the plug rod; one end of the plug rod close to the action rod is wedge-shaped, and the wedge-shaped end face of the plug rod faces the action rod.

[0004] The above-mentioned Hall sensor in the prior art still has certain deficiencies in actual use. For example, the Hall sensor may still displace through the lower sliding hole and in combination with the elastic limit block at the sliding hole, and it is impossible to monitor the displacement accuracy of the displaced Hall sensor, nor can it guarantee the displacement reset of the Hall sensor body. Therefore, a micro-displacement high-precision measurement rebound Hall sensor is needed now. Content of the Utility Model

Detailed Embodiment

[0024] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] The present utility model provides: a micro-displacement high-precision measurement rebound Hall sensor, as Figures 1-6 shown, which includes a Hall sensor body 1, and the Hall sensor body 1 is installed on the upper part of a first mounting seat 7; two groups of positioning rods 3 are fixedly installed on both sides of the Hall sensor body 1, and a punctuation mark 6 is embedded and installed at the center of the bottom of the Hall sensor body 1; an installation groove 9 is opened in the middle of the first mounting seat 7, and an observation window 12 is penetratedly opened at the position corresponding to the punctuation mark 6 in the center of the installation groove 9, and a monitoring probe 16 is embedded and installed inside the observation window 12; clamping grooves 13 are opened on both sides of the installation groove 9, and a group of electric push rods 19 are arranged inside each group of clamping grooves 13.

[0027] Preferably, a connecting seat 2 is arranged on the front side of the Hall sensor body 1, a group of limiting plates 4 are fixedly installed at the outer ends of each group of positioning rods 3, two groups of bottom grooves 5 are symmetrically opened at the bottom end of the Hall sensor body 1, and two groups of vertical extended punctuation marks are symmetrically installed on the outer arc surface of the punctuation mark 6. The connecting seat 2 installed on the front side of the Hall sensor body 1 is used to connect the circuit to ensure the normal use of the Hall sensor body 1. The positioning rods 3 installed on both sides of the Hall sensor body 1 and the limiting plates 4 installed at the outer ends of the positioning rods 3 are used to cooperate with the electric push rods 19 and the push plate 20 to ensure the accurate reset and rebound of the Hall sensor body 1, so that the Hall sensor body 1 is maintained at a stable working position. The bottom grooves 5 opened at the bottom of the Hall sensor body 1 cooperate with the second mounting seat 10 and the auxiliary rollers 11 to make the positioning of the Hall sensor body 1 more stable during reset. The punctuation mark 6 installed at the bottom of the Hall sensor body 1 and the extended punctuation marks on the outer arc surface of the punctuation mark 6 make the punctuation mark 6 easier to be captured, and better cooperate with the monitoring probe 16 to monitor the displacement distance of the Hall sensor body 1, improving the capture position accuracy.

[0028] Further, a set of positioning holes 8 are respectively formed through the left and right sides of the first mounting base 7. Two second mounting bases 10 are symmetrically installed inside the mounting groove 9 corresponding to the position of the bottom groove 5. A number of auxiliary rollers 11 are installed on the upper part of each group of second mounting bases 10. The Hall sensor body 1 is installed inside the mounting groove 9. The auxiliary rollers 11 are rotatably installed in contact with the inner wall of the bottom groove 5. The positioning holes 8 formed on both sides of the first mounting base 7 limit the use position of the first mounting base 7, and the mounting groove 9 formed in the middle of the first mounting base 7 limits the mounting position of the Hall sensor body 1. The second mounting bases 10 and the auxiliary rollers 11 installed inside the mounting groove 9 further prevent the front and back positions of the Hall sensor body 1 and ensure that the Hall sensor body 1 rebounds and resets more sensitively.

[0029] Specifically, an inclined angle is formed at the upper opening position of the observation window 12. A protection box 14 is inserted and installed inside the observation window 12. A base 15 is installed at the bottom of the protection box 14. The base 15 is hermetically inserted into the observation window 12, and the top end of the protection box 14 is parallel to the lower inclined end of the upper port of the observation window 12.

The protection box 14 and the base 15 limit the monitoring probe 16 and the supplementary light lamps 17, improving the stability of their use. Since the top end of the protection box 14 does not contact the punctuation 6, the supplementary light lamps 17 can better illuminate the punctuation 6, enabling the monitoring probe 16 to capture more precisely.

[0030] It should be noted that a limit box 18 is inserted inside the card slot 13. The electric push rod 19 is installed inside the limit box 18, and a push plate 20 is bolted to the telescopic end of the electric push rod 19. Limiting holes 22 are formed through the corresponding sides of the two limit boxes 18. The limit box 18 limits the electric push rod 19, and the limit plate 4 and the push plate 20 are located inside the limit box 18 in contact with each other, and the surfaces of the limit plate 4 and the push plate 20 are in contact with the inner wall of the limit box 18, further ensuring that the displacement of the Hall sensor body 1 is more precise. The connection head 21 installed at the top end of the electric push rod 19 enables the electric push rod 19 to communicate with the outside, keeping the electric push rod 19 in a standby excitation state all the time, and being able to quickly ensure the displacement reset of the Hall sensor body 1.

[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
