Description

Technical Field

[0001] This utility model relates to the field of solder bar technology, specifically to a structure for an anti-splatter solder bar. Background Technology

[0002] Tin-lead solder bars are soldering electrodes used for soldering. Soldering can be used for sealing metal welding where high temperature and pressure are not required.

[0003] Modern tin-lead solder bars are used by heating them with a soldering gun to melt the tin and lead into the object and fix it in place.

[0004] The prior art patent application with publication number CN209664629U describes a method that releases internal stress during soldering by creating grooves on the upper surface of the solder bar body, thus reducing spatter and improving soldering quality. However, existing solder bars are made by mixing and pressing flux and tin. When the solder bar is melted and soldered at high temperatures, it cannot release internal stress, which can easily cause spatter when the operator handles the solder bar for soldering. This results in molten solder sticks splashing onto the operator's skin and clothing. Utility Model Content

[0016] 1. This utility model, through the cooperation of a movable block, clamping plate, and transparent cover, allows the transparent cover to block molten solder spatter during use without affecting the operator's observation during soldering.

[0026] By employing the coordinated structure of movable block 17, clamping plate 20, and transparent cover 2, the transparent cover 2 can block molten solder spatter during use without affecting the operator's observation during soldering. Before soldering, the solder bar is placed between clamping plate 20 and movable block 17, and the elastic potential energy of spring 19 causes clamping plate 20 to press against the inner wall of movable block 17, thus fixing the solder bar. The length of the solder bar extending inside the transparent cover 2 can be adjusted by pushing adjusting block 4. The position of the extended solder bar can be restricted by the setting of limiting block 8 and roller 9 to prevent the solder bar from skewing after extending and affecting the soldering operation.

The threaded rod 15 can adjust the distance between the two limiting blocks 8 according to the size of the solder bar, so that the device can be used for solder bars of different sizes.

[0029] Specifically, in this embodiment, the limiting block 8 is provided with a rotating hole 11, and a rotating shaft 12 is rotatably installed in the rotating hole 11. The rotating shaft 12 is installed on the threaded rod 15.

[0030] The rotating shaft 12, connected by the rotating hole 11, allows the rotating shaft 12 to rotate along the rotating hole 11 when the threaded rod 15 rotates, without affecting the position of the limit block 8.

[0031] Specifically, in this embodiment, a limiting slide bar 7 is provided inside the transparent cover 2, and two limiting blocks 8 are slidably arranged on the limiting slide bar 7.

[0032] By cooperating with the limiting slide bar 7, the movement direction of the limiting block 8 can be guided and restricted.

[0033] Specifically, in this embodiment, a lighting lamp 6 is provided inside the transparent cover 2, and a hanging ring 10 is provided at the end of the main body 1 away from the transparent cover 2.

[0034] Specifically, in this embodiment, limiting grooves 14 are provided on both sides of the inner wall of the sliding cavity 13, and two mutually symmetrical limiting sliders 16 are provided on the movable block 17 and are adapted to the limiting grooves 14.

[0035] By cooperating with the limiting slide 14, the movement direction of the limiting slide 16 can be guided and the movement range of the limiting slide 16 can be limited.

[0036] Specifically, in this embodiment, the end of the clamping plate 20 away from the connecting rod 18 is provided with an anti-slip rubber sheet 21, which can ensure the friction between the clamping plate 20 and the solder bar and improve the clamping stability.
