Description

A guided positioning probe

Technical Field

The utility model relates to the technical field of probes, and more specifically, to a guiding and positioning probe.

Background Art

The probe is a precision connector used in mobile phones and other electronic products. The spring probe usually includes a needle shaft, a needle tube and a spring. The spring is set in the needle tube, and the needle shaft is inserted in the needle tube. When the needle shaft is squeezed by the components, the spring is compressed and moves axially. The outer surface of the needle shaft contacts the inner surface of the needle tube, and the electrical signal is transmitted from the needle shaft to the needle tube. The existing guided positioning probes require different probe shapes for detection in different scenarios in the studio. Because multiple detections require multiple probes of different forms, it is troublesome to carry and affects efficiency.

To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a guiding and positioning probe, comprising a needle body, a screw hole is opened inside the needle body, a stud is meshed inside the screw hole, a needle head is fixedly installed on the bottom of the stud, a limiting plate 1 is fixedly installed on the top of the needle body, a spring is fixedly installed on the bottom of the limiting plate 1, a limiting plate 2 is fixedly installed on the bottom of the spring, a shell is fixedly installed above the limiting plate 2, and a clamping wheel is fixedly installed on the surface of the shell.

As a preferred technical solution of the utility model, the top diameter of the needle is equal to the diameter of the needle body, and the bottom of the needle is pointed.

As a preferred technical solution of the utility model, the diameter of the limiting plate 1 is greater than the diameter of the needle body, and the spring is located in the upper half of the needle body.

As a preferred technical solution of the utility model, the needle body and the spring are both located inside the shell, and the interior of the shell is hollow.

As a preferred technical solution of the utility model, the diameter of the clamping wheel is greater than the diameter of the housing, and a plurality of anti-slip grooves are provided on the surface of the clamping wheel.

As a preferred technical solution of the utility model, the needle body and the needle head are in contact with each other, and the stud is located inside the needle body.

Compared with the prior art, the beneficial effects of the utility model are as follows:

1. The utility model has a screw hole formed inside the needle body, a stud is meshed inside the screw hole, and a needle is fixedly installed at the bottom of the stud. When different materials need to be tested, needles of different shapes will be used for testing, and it is necessary to carry a lot of probes of different shapes. At this time, the stud is removed from the inside of the needle body, and needles of different shapes are installed, so that the needle can be directly replaced, which improves work efficiency and saves the trouble of carrying.

2. The utility model has a spring sleeved on the surface of the needle body, and the spring is in contact with the surface of the needle body. When the device is working normally, the spring will provide elastic force outward. At the same time, since the needle body is located inside the spring, the spring is effectively prevented from bending around, thereby ensuring that the spring will always provide elastic force forward.

DETAILED DESCRIPTION

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

As shown in Figures 1 to 5, the utility model provides a guiding and positioning probe, including a needle body 1, a screw hole 2 is opened inside the needle body 1, a stud 3 is meshed inside the screw hole 2, a needle head 4 is fixedly installed at the bottom of the stud 3, a limit plate 5 is fixedly installed on the top of the needle body 1, a spring 6 is fixedly installed at the bottom of the limit plate 5, a limit plate 2 7 is fixedly installed at the bottom of the spring 6, a shell 8 is fixedly installed above the limit plate 2 7, and a clamping wheel 9 is fixedly installed on the surface of the shell 8;

The needle body 1 is cylindrical, and its main function is to play a certain guiding role, by guiding data such as current, so as to achieve the detection effect of the material.

The top diameter of the needle 4 is equal to the diameter of the needle body 1, and the bottom of the needle 4 is pointed;

The needle 4 is conical in shape, and its main function is to contact with the test material so as to quickly locate the place where the test is required, thereby improving the accuracy of the test.

The diameter of the limit plate 5 is greater than the diameter of the needle body 1, and the spring 6 is located in the upper half of the needle body 1;

The main function of the limit plate 5 is to limit the spring 6 to a certain extent, to ensure that the elastic force provided by the spring 6 is always present, and to ensure that the spring 6 will not be deformed.

The needle body 1 and the spring 6 are both located inside the housing 8, and the interior of the housing 8 is hollow;

The main function of the shell 8 is to enable the shell 8 to be installed in contact with the detection platform, so as to ensure that the needle body 1 can slide inside, thereby improving the accuracy of the detection.

The diameter of the card wheel 9 is greater than the diameter of the housing 8, and a plurality of anti-skid grooves are provided on the surface of the card wheel 9;

The clamping wheel 9 is clamped with the detection platform to ensure the overall stability of the probe and prevent the probe from rotating internally during detection.

The needle body 1 and the needle head 4 are in contact with each other, and the stud 3 is located inside the needle body 1;

The main function of the stud 3 is to engage with the screw hole 2, thereby ensuring the detachability of the needle 4, thereby ensuring that different needles 4 can be replaced for testing when facing the testing of different materials.

The working principle and use process of this utility model:

First, the needle 4 is engaged with the screw hole 2 through the stud 3, so that the needle 4 contacts the needle body 1, and the needle 4 is installed;

Secondly, the device is installed as a whole on the detection instrument to ensure that the device can complete normal detection. When different materials need to be detected, the needle 4 is removed and then a needle 4 of a different shape is installed, so that the needle 4 can be directly replaced, which improves work efficiency and saves the trouble of carrying.

At this time, since the surface of the needle body 1 is sleeved with the spring 6, when the device is working normally, the spring 6 will not bend in all directions due to the limiting effect of the needle body 1, thereby ensuring the stability of the spring 6.
