DETAILED DESCRIPTION

[0017] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] In the description of the present utility model, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. The present utility model is further described in detail below in conjunction with the accompanying drawings.

[0019] like Figure 1-4As shown, the utility model proposes a welding frame for a civil air defense door frame, comprising a fixed seat 1, a movable seat 2 and a slide 3, the fixed seat 1 is provided with a spacing adjustment member 4, the movable seat 2 is arranged on the spacing adjustment member 4, the top wall of the movable seat 2 is provided with a positioning seat 6, the slide 3 slides through the movable seat 2, and the slide 3 is provided with a clamping seat 5, the distance between the two movable seats 2 and the distance between the slides 3 are adjusted according to the required width of the door frame, so as to position the steel plates on both sides through the positioning seat, and then the distance between the upper and lower relative slides 3 is adjusted according to the required height of the door frame, so as to facilitate the clamping seat 5 on the slide 3 to position the steel plates at the upper and lower ends.

[0020] The spacing adjustment member 4 includes a bidirectional lead screw 7, a lead screw pair 8 and a connecting seat 9. The bidirectional lead screw 7 rotates through the fixed seat 1 and extends at both ends. The bidirectional lead screw 7 has no threaded connection with the fixed seat 1. A limit rod 10 is provided on the fixed seat 1. The lead screw pair 8 is threadedly connected to the bidirectional lead screw 7 and is slidably sleeved on the limit rod 10. The lead screw pair 8 is relatively provided with two groups. The movable seat 2 is arranged on the lead screw pair 8. The connecting seat 9 is arranged at the end of the limit rod 10. The two ends of the bidirectional lead screw 7 are rotatably arranged on the connecting seat 9. The side wall of the connecting seat 9 is provided with a handle 14. The end of the handle 14 rotates through the connecting seat 9 and is connected to the bidirectional lead screw 7. By rotating the bidirectional lead screw 7, the two lead screw pairs 8 are driven to drive the movable seats 2 thereon to move away from or approach each other, so as to drive the positioning seat 6 thereon to position the steel plates on the left and right sides, so that they can be spliced ​​and approached with the steel plates at the upper and lower ends for easy welding.
