[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-3 As shown, a portable lightweight protective device for welding steel tie rods includes a protective plate 1, a locking block 2 on the lower surface of the protective plate 1, and a connecting plate 201 on the rear surface of the protective plate 1. The advantage of this arrangement is that the connecting plate 201 can protect the welding slag generated during the welding of the steel tie rod.

[0023] Furthermore, a limiting slide rod 202 is slidably installed through the surface of the connecting plate 201, and a second locking block 203 is installed at the end of the limiting slide rod 202 near the locking block 2. A return spring 204 is provided on the outer surface of the end of the limiting slide rod 202 away from the locking block 2. The advantage of this setting is that, through the setting of the return spring 204, when welding steel tie rods outdoors, the return characteristic of the return spring 204 can drive the limiting slide rod 202 to slide inward and bring the second locking block 203 close to the locking block 2, so as to quickly clamp and fix the protective plate 1, thereby improving the adaptability of the protective plate 1. At the same time, after use, the second locking block 203 can be pulled open by the pull plate 209, so that the protective plate 1 can be quickly removed for easy carrying and use.

[0024] Furthermore, the outer surface of the end of the limiting slide bar 202 is provided with a threaded groove 205, and a pressure ring 206 is spirally installed on the outer surface of the threaded groove 205. The pressure ring 206 and the return spring 204 are configured to be in frictional connection. The advantage of this configuration is that, by setting the pressure ring 206, the return spring 204 can be compressed by moving spirally along the threaded groove 205, thereby increasing the pressure of the return spring 204 and improving the installation stability of the protective plate 1.

[0025] Furthermore, a limiting groove 207 is provided on the upper surface of the connecting plate 201, and a connecting rod 208 is slidably installed on the inner surface of the limiting groove 207. The lower surface of the connecting rod 208 is fixedly connected to the limiting rod 202, and a pull plate 209 is provided on the outer surface of the connecting rod 208. The advantage of this setting is that, by pulling the connecting rod 208, the limiting rod 202 can be slid to open the second locking block 203.

[0026] like Figure 4 As shown, a second protective plate 301 is rotatably mounted on the inner surface of the first protective plate 1, and a threaded locking rod 3 is screwed onto the outer right side surface of the first protective plate 1. Furthermore, an observation window 302 is provided on the surface of the second protective plate 301. The advantage of this arrangement is that the second protective plate 301 can be fixed by screw fixing after the angle adjustment through the setting of the threaded locking rod 3.

[0027] Furthermore, a third protective plate 401 is slidably installed through the inner surface of the second protective plate 301, and an observation window 2 4 is provided on the surface of the third protective plate 401. The advantage of this design is that, by installing the third protective plate 401, the protected area can be increased on top of the protection provided by the second protective plate 301. When welding steel tie rods outdoors, it can protect welding workers from injury caused by flying weld slag. At the same time, it can also be quickly retracted into the pull plate 403 after welding, reducing the size of the protective device and making it easy to carry and use.

[0028] Furthermore, the protective plate 3 401 has limit plates 402 on both ends of its surface, and the lower surface of the limit plate 402 at the end of the protective plate 3 401 has a pull plate 2 403. The advantage of this arrangement is that the position of the protective plate 3 401 can be restricted by the limit plate 402, preventing it from sliding out of the interior of the protective plate 2 301.

[0029] Furthermore, the inner surface of the limiting plate 402 is provided with a magnetic strip 404, and the magnetic strip 404 is magnetically connected to the second protective plate 301. The advantage of this setting is that the magnetic strip 404 can be used to magnetically fix the third protective plate 401 when it is slid out for use or slid in for storage.

[0030] Working Principle: When using this portable lightweight steel tie rod welding protective device, firstly, when welding the steel tie rod outdoors, pull the pull plate 209 to move the limiting slide rod 202 outward, opening the locking block 203. After placing it on a suitable platform surface, release the pull plate 209. Its return spring 204 will drive the limiting slide rod 202 to return to its original position, causing the locking block 203 to approach the locking block 203 to clamp and fix the protective plate 1. After clamping, the pressure ring 206 can be rotated to press the return spring 204 along the threaded groove 205, making the fixation of the protective plate 1 more secure. Before welding, first release the restriction between the protective plate 201 and the protective plate 1 using the threaded locking rod 3, then adjust the angle of the protective plate 201. After adjusting the angle, use the threaded locking rod 3 to fix the protective plate 201 again. After adjustment, pull the second pull plate 403 to pull the third protective plate 401 and slide it along the inner surface of the second protective plate 301. At the same time, the limiting plate 402 at the end of the third protective plate 401 is attached to the inner surface of the second protective plate 301, and the magnetic strip 404 fixes the third protective plate 401 by magnetic attraction. This completes the installation of the protective device. This is the working principle of the portable lightweight steel tie rod welding protective device.
