DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 to 3 , the present utility model provides a technical solution:

[0022] A workbench for the welding process of a civil air defense door, including a workbench body 1,

[0023] At both ends of the top of the workbench body 1, there are placement seats 5 for placing civil air defense doors, and at the top of the placement seat 5, there is a connection seat 11. Four groups of blowers 12 for ventilation work are installed on the outside of the connection seat 11. A suction head 13 corresponding to the blower 12 is installed inside the connection seat 11. The suction head 13 is connected to one end of the blower 12. Four groups of bumps 10 are installed at the bottom of the connection seat 11. The four groups of bumps 10 are clamped in corresponding grooves 9 opened at the top of the placement seat 5, and the grooves 9 and the bumps 10 are adapted to each other; by providing the grooves 9 and the bumps 10, it is convenient for the connection seat 11 to play the role of disassembly and installation, so as to repair the blower 12 on the connection seat 11, and also facilitate its carrying.

[0024] The present utility model is used in cooperation with components such as the groove 9, the bump 10, the connection seat 11, the blower 12, and the suction head 13, so as to facilitate the ventilation of harmful gases and fumes generated during the welding process of the civil air defense door, so as to eliminate the harmful gases and fumes, and also play a certain role in protecting the health of workers, and further improve the comfort of the working environment.

[0025] By starting the blower 12, the suction head 13 on its absorption end absorbs and ventilates and eliminates the harmful gases and fumes generated during the welding process of the civil air defense door, so as to play a certain role in protecting the health of workers, and also improve the comfort of the working environment.

[0026] When it is necessary to disassemble and repair the ventilation structure, by hand-picking up the connection seat 11, the bumps 10 provided at the bottom thereof are moved upward out of the groove 9, so as to disassemble the connection seat 11 from the placement seat 5, thereby facilitating the repair, replacement and carrying of the ventilation structure on the connection seat 11. On the contrary, by operating in reverse, it can be installed.

[0027] Below the inner side of the placement seat 5, there is a pressing plate 8 for pressing and fixing the civil air defense door. A number of adjusting blocks 7 are installed on one side of the pressing plate 8 close to the placement seat 5. The adjusting blocks 7 are clamped in corresponding adjusting grooves 6 opened below the inner side of the placement seat 5, and the adjusting grooves 6 and the adjusting blocks 7 are adapted to each other.

[0028] By using components such as the adjusting groove 6, the adjusting block 7, and the pressing plate 8 in cooperation, it is convenient for the pressing plate 8 to play the role of height adjustment, so as to press and fix civil air defense doors of different thicknesses, and also facilitate the pressing plate 8 to be disassembled and replaced.

[0029] On both sides of the workbench body 1, electric telescopic rods 2 are installed, and at both ends of the top of the workbench body 1, moving grooves 3 are opened. The output ends of the electric telescopic rods 2 penetrate into the inside of the moving grooves 3 and are fixedly connected with moving blocks 4. The moving blocks 4 are slidably connected with the moving grooves 3, and a placement seat 5 is installed on the top of the moving blocks 4.

[0030] By starting the electric telescopic rod 2, its output end drives the moving block 4 to move left and right in the moving groove 3 for adjustment, so that the moving block 4 drives the placement seat 5 thereon for adjustment. After adjusting to a width suitable for positioning the civil air defense door, stop.

[0031] At the center of the top of the workbench body 1, a storage groove 14 for welding slag collection is opened, and sliding grooves 16 are opened on both side walls at the front end of the storage groove 14. Sliding plates are slidably connected inside the sliding grooves 16, and a baffle 15 is installed on the inner side of the sliding plates.

[0032] By hand-held the baffle 15, the sliding plates provided at both ends thereof are moved upward from the sliding grooves 16 opened on the side wall of the storage groove 14, so as to open the storage groove 14, thereby facilitating the cleaning of the welding slag stored therein. Conversely, by operating, the baffle 15 is installed to block it.

[0033] At the center of the back of the workbench body 1, a double-acting cylinder 17 is installed, and the output end of the double-acting cylinder 17 penetrating into the inside of the storage groove 14 is installed with a cleaning plate 18 for welding slag cleaning. The cleaning plate 18 is in sliding fit with the storage groove 14. By starting the double-acting cylinder 17, its output end drives the cleaning plate 18 to move back and forth in the storage groove 14, so as to push the welding slag stored inside the storage groove 14 to the outside, thereby facilitating the cleaning of the inside of the storage groove 14.

[0034] During specific use, by starting the fan 12, the suction head 13 on its absorption end absorbs and ventilates and eliminates the harmful gases and smoke generated during the welding process of the civil air defense door, so as to provide a certain guarantee for the physical health of the workers, and also improves the comfort of the working environment.

[0035] When it is necessary to disassemble and repair the ventilation structure, by hand-held the connecting seat 11, the convex block 10 provided at its bottom is moved upward from the groove 9, so as to disassemble the connecting seat 11 from the placement seat 5, thereby facilitating the repair, replacement and carrying of the ventilation structure on the connecting seat 11. Conversely, by operating, it can be installed.

[0036] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
