Description

Technical Field

[0001] The utility model relates to a resistance detection device for heating wire production, belonging to the field of heating wire production. Background Art

[0002] Resistance testing is a key process to ensure that the performance of heating wires meets design requirements. It is mainly used to measure parameters such as the resistance value, resistance uniformity, and temperature coefficient of the heating wire, which directly affect the heating efficiency, safety, and service life of the heating wire. Multimeters are commonly used instruments for heating wire resistance testing. Resistance measurement is usually achieved by connecting a test pen with two cables. To accommodate heating wires of different lengths, the cable must be long enough to flexibly adjust the position of the test pen. However, this design has significant disadvantages in actual operation:

[0003] When testing longer heating wires, the lengthy cable can easily shake due to operator activity or equipment vibrations while adjusting the test pen's position. This can cause repeated stress on the cable's connection to the multimeter, resulting in mechanical wear and tear on the plug and socket, leading to measurement errors. Furthermore, a loose connection can cause momentary power outages, disrupting the continuity of test data. For shorter heating wires, excessive cable length can create significant redundancy, and accumulated cables can become entangled in equipment or operators, obstructing operations and impacting the cleanliness of the testing environment. In high-frequency testing scenarios, disorganized cable management can lead to reduced testing efficiency. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a resistance detection device for heating wire production to solve the problems raised in the above background technology. The present invention reinforces the end of the cable close to the multimeter and stores redundant cables.

[0005] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions: a resistance detection device for heating wire production, comprising a multimeter, two cables are plugged into the top of the multimeter, a detection pen is installed at the end of the cable away from the multimeter, and a conductive clamp connected to the detection pen for clamping on the heating wire is sleeved on the end of the detection pen away from the cable, a base plate is plugged into the bottom of the multimeter, side plates are installed at both ends of the base plate, a plurality of pipe columns for limiting the position of the cables are evenly installed on the side of the side plate away from the multimeter, a holding plate is provided on the side of the pipe column away from the side plate, and the holding plate is connected to the side plate by two sets of screws.

[0006] Furthermore, protrusions are processed at the two corners of the bottom of the multimeter, and two supports are installed on the upper surface of the base plate. The upper surface of the support is recessed downward to form a limiting groove, and the protrusions are inserted into the limiting groove.

[0007] Further, a suspension plate is fixedly connected to the upper end of the pressing plate. Two through holes are formed in one side surface of the suspension plate, and two screw holes aligned with the through holes are formed in the surface of the side plate facing the suspension plate. The screw passes through the through hole and is threadedly connected to the screw hole.

[0008] Further, a plurality of transverse grooves are formed by recessing the surface of the multimeter facing the side plate, and one end of the screw extends into the transverse groove.

[0009] Further, two symmetrically arranged L-shaped plates are installed on the lower surface of the bottom plate. A threaded hole is formed in the upper surface of the horizontal portion of the L-shaped plate. A stud is threadedly connected to the threaded hole. A knob head is installed at the lower end of the stud, and a pressing disc is installed at the upper end of the stud.

[0010] Further, a rubber pad is pasted on the upper surface of the pressing disc through glue, and the outer diameter of the rubber pad is the same as the outer diameter of the pressing disc.

[0011] Further, soft rubber strips are provided on both side surfaces of the side plate adjacent to the pipe column. The cross section of the soft rubber strip is semicircular.

[0012] Advantages of the present utility model:

[0014] 2. The redundant parts of the cable during the detection of the short heating wire are stored in an "S" shape on a plurality of pipe columns and limited by the pressing plate, so that the length of the cable that can move is shortened, which is beneficial to maintaining the cleanliness of the working environment.

[0015] 3. The two protruding parts on the multimeter are respectively inserted into the corresponding limiting grooves, and then one end of the screw extends into the transverse groove on the multimeter to limit the position of the multimeter. At this time, the screw limits the position of the multimeter while limiting the pressing plate. The structure formed by the stud and the L-shaped plate limits the bottom plate at the edge of the table, completing the limitation of the position of the multimeter. Description of the drawings

The tube columns 19 on the side plate 2 form spaced support for the cable 9. In cooperation with the pressing plate 4, the cable 9 is fixed into an "S"-shaped path, minimizing the influence of the shaking of the cable 9 on the plugging part of the cable 9 and the multimeter 1 during the detection process, reducing the mechanical wear rate of the plug at one end of the cable 9 and the socket on the multimeter 1. The redundant part of the cable 9 during the detection of the short heating wire is stored in an "S" shape on a plurality of tube columns 19 and limited by the pressing plate 4, so that the movable length of the cable 9 is shortened, which is beneficial to maintaining the cleanliness of the working environment.

[0026] Refer to Figures 1 - 5 , convex portions 15 are processed at both corners of the bottom of the multimeter 1. Two supports 7 are installed on the upper surface of the base plate 8.
