Technical Field
[0001] This utility model relates to the field of solder wire testing, specifically a solder wire tensile testing device. Background Technology
[0002] Solder wire is an important industrial raw material used in the electronics industry, home appliance manufacturing industry, automobile manufacturing industry and other fields to connect electronic components. It is composed of tin alloy and additives. In the soldering process, it plays a role in conducting heat, removing oxidation, and reducing surface tension, thereby achieving reliable electrical connection and mechanical fixation between electronic components. With the continuous development of technology, electronic devices are increasingly developing towards miniaturization, high performance and multi-functionality. This has put forward higher requirements for the quality and performance of solder wire. Tensile strength is one of the important indicators for evaluating the quality of solder wire. Through tensile testing, we can understand the performance of solder wire under tensile force, including parameters such as the maximum tensile force it can withstand and elongation. This allows us to determine whether the solder wire meets relevant standards and usage requirements. Therefore, a solder wire tensile testing device is needed.
[0003] Existing solder wire tensile testing devices are inconvenient for quick installation of the solder wire pulling position and tensile components during operation, and are also inconvenient for fixing the solder wire to prevent loosening. Therefore, there is an urgent need for a solder wire tensile testing device. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a solder wire tensile testing device, comprising a base, wherein a fixing cone is welded to the outer wall of the base, the outer wall of the fixing cone abuts against the solder wire body, and the outer wall of the solder wire body abuts against a tightening cone.
[0006] An elongation measuring bracket is welded to the outer wall of the base. A rotating gear is installed on the inner wall of the elongation measuring bracket. A rubber sleeve is fitted to the outer wall of the rotating gear. A lifting rod is meshed with the outer wall of the rotating gear. Both sides of the lifting rod abut against a locking block. A first spring is welded to one side of the locking block. A tensile tester is welded to the outer wall of the lifting rod. A connecting frame is fixedly connected to the lower end of the tensile tester. A second spring is welded to the inner wall of the connecting frame. A first buckle is welded to one end of the second spring. A second buckle is installed at one end of the first buckle.
[0007] Preferably, the base is threadedly connected to the tightening cone, and the tightening cone is symmetrically arranged about the central axis of the base.
[0008] Preferably, the elongation measuring bracket is engaged with the locking block, and the locking block is symmetrically arranged with respect to the central axis of the elongation measuring bracket.
[0009] Preferably, the outer wall of the rotating gear frame is in close contact with the inner wall of the rubber sleeve, and the diameter of the outer wall of the rotating gear frame is smaller than the diameter of the inner wall of the rubber sleeve.
[0010] Preferably, the tensile tester is threadedly connected to the connecting frame, and the connecting frame is perpendicular to the second spring.
[0011] Preferably, the connecting frame is movably connected to the first buckle, and the inner wall of the connecting frame is designed with openings.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This utility model uses a base to thread-fix the tightening cone. When using the device, the misalignment of the tightening cone and the fixing cone facilitates the tightening of the solder wire body after it is fixed, preventing the solder wire body from loosening and increasing the practicality of the device.
[0014] This utility model uses a connecting frame to enable the first buckle to move. When the device is in use, the first buckle and the second buckle open by contacting the solder wire body. At the same time, after the solder wire body enters the inner wall of the connecting frame, the second spring quickly closes the first buckle and the second buckle by contacting them, which facilitates the rapid installation of the solder wire body at the pulled position and increases the practicality of the device.

The base 1 and the tightening cone 4 are threadedly connected, and the tightening cone 4 is symmetrically arranged about the central axis of the base 1. The base 1 provides a threaded fixation for the tightening cone 4. When using the device, the tightening cone 4 and the fixing cone 2 are staggered to facilitate the fixing and tightening of the solder wire body 3, preventing the solder wire body 3 from loosening and increasing the practicality of the device.

A lifting rod 8 is meshed with the outer wall of the rotating gear 6. Locking blocks 9 abut against both sides of the lifting rod 8. The elongation measuring bracket 5 is engaged with the locking blocks 9, which are symmetrically arranged about the central axis of the elongation measuring bracket 5. The outer wall of the rotating gear 6 is tightly fitted to the inner wall of the rubber sleeve 7, and the diameter of the outer wall of the rotating gear 6 is smaller than the diameter of the inner wall of the rubber sleeve 7. A first spring 10 is welded to one side of the locking blocks 9. A tensile tester 11 is welded to the outer wall of the lifting rod 8. A connecting frame 12 is fixedly connected to the lower end of the tensile tester 11. The inner wall of the connecting frame 12 is welded with… A second spring 13 is provided.

A second buckle 15 is installed on one end of the first buckle 14. By setting the connecting frame 12, the first buckle 14 can be moved. When using the device, the first buckle 14 and the second buckle 15 abut against the solder wire body 3 and open it. At the same time, after the solder wire body 3 enters the inner wall of the connecting frame 12, the second spring 13 abuts against the first buckle 14 and the second buckle 15 and quickly closes it, which facilitates the quick installation of the solder wire body 3 in the pulled position and increases the practicality of the device.
[0025] Working principle: In use, take out the device and place it in the designated position. Secure the tensile tester 11 to the connecting frame 12 with threads.
