Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and in particular to a portable low-voltage signal detection probe. Background Technology

[0002] Currently, during the installation, commissioning, and maintenance of electrical equipment, it is often necessary to detect low-voltage signals in the circuit to determine whether the line is working properly or if a fault exists. Common testing tools typically include voltage probes, test pens, or low-voltage signal detectors. These devices can meet the testing needs to a certain extent, but they still have some shortcomings in practical use.

[0003] Most existing low-voltage signal detection probes adopt a fixed structure, leaving them exposed when not in use and susceptible to environmental factors such as dust, moisture, or accidental impacts, leading to damage and a shortened lifespan. Furthermore, some devices lack effective sealing and protection during transport, making them vulnerable to humid or water-infiltrated environments, which can affect circuit performance and even cause device failure. In addition, the disassembly and assembly of existing probes are not convenient enough; replacing batteries or maintaining internal components often requires tools, making the process complex and hindering quick on-site handling. Utility Model Content

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a portable weak current signal detection probe, comprising: a shell; a groove formed on the top of the shell, wherein an upper shell is movably embedded inside the groove; a convex ring fixedly installed on the bottom of the upper shell, the size of the convex ring being equal to the size of the inner wall of the groove, the convex ring being located inside the groove; U-shaped blocks being fixedly installed around the top of the shell; threaded rods being movably embedded inside the multiple U-shaped blocks; and circular holes being formed around the upper shell, wherein the multiple threaded rods are movably embedded inside the multiple circular holes for limiting the position of the upper shell.

[0005] The technical effect of adopting the above-mentioned further solution is that by rotating the threaded rod one and moving it inside the U-shaped block, the threaded rod one disengages from the locking holes around the upper shell. At this time, the upper shell can be removed from the top of the outer shell, which is convenient for disassembly and installation. The convex ring is embedded in the groove, which makes the interior of the outer shell more sealed. The convex ring is made of rubber and has a certain sealing effect, preventing water from entering the interior of the outer shell.

[0006] In a preferred embodiment, a battery is detachably installed inside the housing, and a wire is electrically connected to one side of the battery. Two grooves are formed at the bottom of the inner wall of the housing.

[0007] The technical advantage of adopting the above-mentioned further solution is that the battery is installed inside the battery slot inside the casing, and then the power is transmitted to the inside of the conductive tube through the wire, and then transmitted to the inside of the voltage probe for detection through the conductive tube.

[0008] In a preferred embodiment, a movable block is slidably connected inside the two slides, a second spring is fixedly installed on one side of the movable block, one end of the second spring is fixedly installed on the inner wall of the outer shell, and a limit strip is fixedly installed on the top of the movable block.

[0009] The technical effect of adopting the above-mentioned further solution is that the lifting block disengages from one side of the limiting strip. After disengagement, the moving block slides inside the slide groove under the elastic force of the second spring. After sliding, the voltage probe extends out from the inside of the protective tube through the conductive tube for detection. When not detecting, the voltage probe is located inside the protective tube, which is mainly used to protect the voltage probe.

[0010] In a preferred embodiment, a conductive tube is fixedly installed on one side of the movable block, a voltage probe is fixedly installed on one side of the conductive tube, a protective tube is fixedly installed on one side of the outer casing, and the voltage probe is movably embedded inside the voltage probe.

[0011] The technical effect of adopting the above-mentioned further solution is that the voltage is transmitted to the inside of the voltage probe through the conductive tube for detection.

[0012] In a preferred embodiment, a U-shaped strip is fixedly installed on the top of the upper shell, a damper is fixedly installed on the bottom of the U-shaped strip, a spring is fixedly installed on the bottom of the U-shaped strip, and a lifting block is fixedly installed on the bottom of both the damper and the spring.

[0013] The technical effect of adopting the above-mentioned further solution is that when no detection is being performed, the voltage probe is located inside the protective tube, and the spring and damper cooperate to limit the lifting block. At this time, the lifting block is located on one side of the limit bar and is limited thereto.

[0014] In a preferred embodiment, a linkage bar is fixedly installed on one side of the lifting block, a cover is fixedly installed on one end of the linkage bar, the cover is located on one side of the protective tube, the lifting block is located on the outer surface of the limiting bar for limiting its movement, and a linkage rod is fixedly installed on one side of the lifting block.

[0015] The technical effect of adopting the above-mentioned further solution is that the damper and the cover are mainly used to limit the lifting block, so that the lifting block can limit the limit strip. The limit strip limits the voltage probe inside the protection tube through the conductive tube, thereby protecting the voltage probe.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by rotating the threaded rod, it moves inside the U-shaped block. At this time, the threaded rod disengages from the locking holes around the upper shell, allowing the upper shell to be removed from the top of the outer shell for easy disassembly and installation. The convex ring is embedded in the groove, making the interior of the outer shell more sealed. The convex ring is made of rubber and has a certain sealing effect, preventing water from entering the interior of the outer shell.

[0017] This invention involves installing a storage battery inside a battery slot within a casing. Power is then transmitted via wires to a conductive tube, which in turn transmits the power to a voltage probe for detection. Before detection, a linkage rod is moved upwards, causing a lifting block to move upwards. This lifting block, in turn, moves a linkage bar upwards, which in turn moves a cover upwards. The cover then detaches from one side of the protective tube, and the lifting block detaches from one side of the limiting bar. After detachment, the moving block slides within a groove under the elastic force of a second spring. This sliding motion, via the conductive tube, causes the voltage probe to extend from inside the protective tube for detection. When not in use, the voltage probe is located inside the protective tube, with a spring and damper working together to limit the lifting block. The cover moves with the lifting block via the linkage bar. When the voltage probe is not in use, it is located inside the protective tube, with the cover shielding one side of the protective tube to protect the probe from water contact and impacts.

Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Please see Figures 1 to 4 This utility model provides a portable low-voltage signal detection probe, comprising: a housing 101; a groove 113 formed on the top of the housing 101, with an upper housing 104 movably embedded inside the groove 113; a convex ring 121 fixedly installed on the bottom of the upper housing 104, the size of the convex ring 121 being equal to the size of the inner wall of the groove 113, the convex ring 121 being located inside the groove 113; U-shaped blocks 102 fixedly installed around the top of the housing 101, with threaded rods 103 movably embedded inside the multiple U-shaped blocks 102; and the upper housing 104 being fixedly installed around its top. All are provided with round holes, and multiple threaded rods 103 are movably embedded in the multiple round holes to limit the upper shell 104. By rotating the threaded rods 103, they move inside the U-shaped block 102. At this time, the threaded rods 103 disengage from the locking holes around the upper shell 104, and the upper shell 104 can be removed from the top of the outer shell 101 for easy disassembly and installation. The convex ring 121 is embedded in the groove 113 to make the interior of the outer shell 101 more sealed. The convex ring 121 is made of rubber and has a certain sealing effect to prevent water from entering the interior of the outer shell 101.

[0023] like Figures 1 to 4 As shown, a battery 117 is detachably installed inside the housing 101. A wire 118 is electrically connected to one side of the battery 117. Two grooves 123 are opened at the bottom of the inner wall of the housing 101. The battery 117 is installed into the battery slot inside the housing 101. Then, the power is transmitted to the inside of the conductive tube 114 through the wire 118, and then transmitted to the inside of the voltage probe 115 through the conductive tube 114 for detection.

[0024] like Figures 1 to 4As shown, two sliding blocks 119 are slidably connected inside the two sliding grooves 123. A second spring 116 is fixedly installed on one side of the sliding block 119. One end of the second spring 116 is fixedly installed on the inner wall of the outer shell 101. A limit strip 122 is fixedly installed on the top of the sliding block 119. The lifting block 107 disengages from one side of the limit strip 122. After disengagement, the sliding block 119 slides inside the sliding groove 123 under the elastic force of the second spring 116. After sliding, the voltage probe 115 is driven to extend out of the inside of the protective tube 120 for detection through the conductive tube 114. When not detecting, the voltage probe 115 is located inside the protective tube 120, which is mainly used for the protection of the voltage probe 115.

[0025] like Figures 1 to 4 As shown, a conductive tube 114 is fixedly installed on one side of the movable block 119, a voltage probe 115 is fixedly installed on one side of the conductive tube 114, a protective tube 120 is fixedly installed on one side of the outer casing 101, and the voltage probe 115 is movably embedded inside the voltage probe 115. The voltage probe is transmitted to the inside of the voltage probe 115 through the conductive tube 114 for detection.

[0026] like Figures 1 to 4 As shown, a U-shaped strip 106 is fixedly installed on the top of the upper shell 104, a damper 111 is fixedly installed on the bottom of the U-shaped strip 106, and a spring 110 is fixedly installed on the bottom of the U-shaped strip 106. A lifting block 107 is fixedly installed on the bottom of both the damper 111 and the spring 110. When no detection is being performed, the voltage probe 115 is located inside the protective tube 120. The spring 110 and the damper 111 cooperate to limit the lifting block 107. At this time, the lifting block 107 is located on one side of the limiting strip 122 and limits it.

[0027] like Figures 1 to 4 As shown, a linkage bar 109 is fixedly installed on one side of the lifting block 107, and a cover 112 is fixedly installed on one end of the linkage bar 109. The cover 112 is located on one side of the protective tube 120. The lifting block 107 is located on the outer surface of the limiting bar 122 for limiting it. A linkage rod 108 is fixedly installed on one side of the lifting block 107. The damper 111 and the cover 112 are mainly used to limit the lifting block 107, so that the lifting block 107 can limit the limiting bar 122. The limiting bar 122 limits the voltage probe 115 inside the protective tube 120 through the conductive tube 114, thereby protecting the voltage probe 115.

[0028] Working principle: During use, the battery 117 is installed inside the battery slot inside the casing 101. Power is then supplied to the conductive tube 114 via the wire 118, and then to the voltage probe 115 for detection. Before detection, the linkage rod 108 is moved upward, which moves the lifting block 107 upward. The lifting block 107 moves the linkage bar 109 upward, which in turn moves the cover 112 upward. At this point, the cover 112 disengages from one side of the protective tube 120, and the lifting block 107 disengages from one side of the limiting bar 122. After disengagement, the moving block 119 slides inside the slide groove 123 under the elastic force of the spring 116. After sliding, the voltage probe 115 extends out of the protective tube 120 for detection via the conductive tube 114. When not detecting, the voltage probe 115 is located inside the protective tube 120. Spring 110 and damper 111 work together to limit the lifting block 107. At this time, the lifting block 107 is located on one side of the limiting strip 122 and is limited thereto. The cover 112 moves up and down with the lifting block 107 via the linkage strip 109. When the voltage probe 115 is not in use, the voltage probe 115 is located inside the protective tube 120. The cover 112 covers one side of the protective tube 120 to protect the voltage probe 115 and prevent it from being bumped by water. By rotating the threaded rod 103, it moves inside the U-shaped block 102. At this time, the threaded rod 103 disengages from the locking holes around the upper shell 104. The upper shell 104 can then be removed from the top of the outer shell 101 for easy disassembly and installation. The convex ring 121 is embedded inside the groove 113 to make the inside of the outer shell 101 more sealed. The convex ring 121 is made of rubber and has a certain sealing effect to prevent water from entering the inside of the outer shell 101.
