[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example: Reference Figure 1-6 The welding protection device shown includes a base 1, a support plate 2 fixed to the upper surface of the base 1, an operating tube 3 fixed to the top of the support plate 2, and a first flame-retardant cloth cover 4 fixed to the left and right ends of the operating tube 3. Two binding ropes 5 are sewn onto the first flame-retardant cloth cover 4. The operating tube 3 has a first reserved groove 6 and two second reserved grooves 8, located to the left and right of the first reserved groove 6 respectively. A glass plate 7 is installed in the first reserved groove 6. The first reserved groove 6 on the operating tube 3 facilitates the installation of the glass plate 7, allowing workers to easily observe the welding points through the glass plate 7. A second flame-retardant cloth cover 9 is installed in the second reserved groove 8. An elastic band 10 is sewn onto one end of the second flame-retardant cloth cover 9 inside the operating tube 3. A second reserved groove 8 is opened on the operating tube 3 to facilitate the installation of the second flame-retardant cloth cover 9. The second flame-retardant cloth cover 9, together with the elastic band 10, allows workers to easily insert their hands, which are wearing protective gloves, into the inside of the operating tube 3 to operate the welding torch and complete the welding operation. A carrier block 11 is fixed at the bottom of the inner side of the operating tube 3. A welding fume purifier 12 and two clamping components are installed on the base 1. The two clamping components are respectively located on the left and right sides of the operating tube 3. A gas supply pipe 13 is fixedly connected between the air inlet of the welding fume purifier 12 and the operating tube 3. An exhaust fan 17 is installed inside the gas supply pipe 13. With the help of the exhaust fan 17, the harmful gases generated by welding inside the operating tube 3 can be better sent to the welding fume purifier 12. The two clamping components are used to clamp the two objects to be welded.

[0024] The welding point is fully wrapped by the operating pipe 3 and two first flame-retardant cloth sleeves 4, so that the sparks and spatter generated during the welding process are blocked inside the operating pipe 3 as much as possible. In this way, the fire hazard can be effectively avoided. In addition, the operating pipe 3 and two first flame-retardant cloth sleeves 4 will block the leakage of harmful gases generated during the welding process as much as possible, so that the harmful gases are absorbed and purified by the welding fume purifier 12 to ensure the safety of the environment and workers.

[0025] The operating tube 3 is provided with a cleaning groove 14, and a cover plate 15 is hinged to the operating tube 3. Two latches 16 are installed on the cover plate 15. The two latches 16 are used to lock the cover plate 15 and the operating tube 3. The cover plate 15 is used to block the cleaning groove 14.

[0026] By opening a cleaning groove 14 on the operating tube 3, it is convenient for workers to clean the glass plate 7 and the inside of the operating tube 3. The cover plate 15, which is hinged to the operating tube 3, can be fixed to the operating tube 3 by means of two latches 16. The cover plate 15 can cover the cleaning groove 14 to prevent sparks, harmful gases and spatters from escaping from the cleaning groove 14 during welding.

[0027] The clamping assembly includes a support plate 18, which is fixedly mounted on the base 1. The top of the support plate 18 is on the same horizontal plane as the top of the carrier block 11. A fixing plate 19 is fixed to the top of the support plate 18. A bolt 20 is threadedly connected to the top of the fixing plate 19. A clamping plate 21 is rotatably connected to the bottom of the bolt 20 through a bearing. Two guide rods 22 are fixed to the top of the clamping plate 21. The two guide rods 22 are symmetrically arranged about the bolt 20. A through hole is provided on the fixing plate 19 for the guide rods 22 to slide. The two guide rods 22 prevent the clamping plate 21 from rotating when it moves in the longitudinal direction.

[0028] Using a wrench to tighten bolt 20 causes bolt 20 to push clamp 21 down. Clamp 21 and support plate 18 cooperate to fix the object to be welded, ensuring that the object will not shake during welding.

[0029] Working principle of this utility model:

[0030] The two objects to be welded are inserted into the inside of the operating tube 3 along the left and right ends of the operating tube 3, so that the welding position is inside the operating tube 3. The two objects to be welded are supported by the carrier block 11 and the two support plates 18. The worker uses a wrench to turn the bolt 20, so that the bolt 20 pushes the clamping plate 21 down. The clamping plate 21, together with the support plate 18, can clamp and fix the objects to be welded. Then, the worker uses the first flame-retardant cloth cover 4 to wrap the objects to be welded, and uses two binding ropes 5 to tie the first flame-retardant cloth cover 4 to the objects to be welded, so as to ensure that the operating tube 3 and the two first flame-retardant cloth covers 4 can form a relatively closed welding cavity.

[0031] Workers inspect the welding points through the glass plate 7, put on protective gloves, and insert their hands into the inside of the operating tube 3 along the second flame-retardant cloth cover 9. The elastic band 10 can tightly wrap the worker's gloves and the second flame-retardant cloth cover 9. Workers operate the welding gun in the operating tube 3, and after putting on goggles, they perform welding operations through the glass plate 7. The sparks and spatter generated during welding are blocked as much as possible inside the operating tube 3. The harmful gases generated during welding are drawn by the exhaust fan 17 and sent to the welding fume purifier 12 along the gas supply pipe 13. The welding fume purifier 12 is used to purify the gases before they are discharged, ensuring the safety of workers and the environment.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
