DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0022] Example: Reference Figure 1-4 An arc welding electrode box shown in the figure includes a box body 1 and a box cover 2. The box body 1 and the box cover 2 are hinged. A placement frame 3 is fixedly installed in the box body 1. A plurality of rectangular sliding holes are opened on the side of the placement frame 3. Extrusion slide plates 4 are slidably installed in the plurality of rectangular sliding holes. The plurality of extrusion slide plates 4 are connected by linkage components. A plurality of clamping and fixing components are arranged on the relative inner walls of the plurality of rectangular sliding holes. The clamping and fixing components include two fixing plates 15. The two fixing plates 15 are slidably installed on the side inner walls of the rectangular sliding holes. The two fixing plates 15 are connected by a control unit. The relative sides of the two fixing plates 15 and the sides of the extrusion slide plates 4 are provided with protective pads.

[0023] With the help of the above structure, when in use, first place multiple welding rods in the placement frame 3 respectively, and then drive multiple extrusion slides 4 to move horizontally synchronously through the linkage component. When multiple extrusion slides 4 move to appropriate positions, the control unit is squeezed, and under the action of the control unit, the two corresponding fixing plates 15 are driven to move synchronously toward each other, and the extrusion slides 4 are used to fix the welding rods from four sides to prevent the welding rods from rubbing and colliding inside, causing the flux to fall off.

[0024] like Figure 3 As shown, the linkage assembly includes four screw rods 5, and four slide grooves are opened on the relative inner walls of the box body 1. The two ends of the four screw rods 5 are rotatably installed on the relative inner walls of the four slide grooves, and multiple extrusion slide plates 4 are respectively threadedly installed on the four screw rods 5. The four screw rods 5 are connected by a transmission unit, and a limiting assembly is arranged on one of the screw rods 5. The advantage of such an arrangement is that through the arrangement of the four screw rods 5, multiple extrusion slide plates 4 can be driven to move synchronously.

[0025] Specifically, when the four screw rods 5 rotate, the multiple extrusion slide plates 4 are driven to move horizontally synchronously under the action of the threads, thereby fixing the welding rods.

[0026] like Figure 3 As shown, the transmission unit includes four sprockets 6, which are fixedly sleeved on four screw rods 5 respectively, and chains 7 are installed on the four sprockets 6 in meshing relationship. The inner walls of the sides of the four slide grooves are provided with avoidance grooves, and the chains 7 are located in the avoidance grooves. One end of one of the screw rods 5 extends outside the box body 1 and is fixedly installed with a knob 8. The advantage of such an arrangement is that the function of driving the four screw rods 5 to rotate synchronously can be achieved through the arrangement of the four sprockets 6 and the chains 7.

[0027] Specifically, when the knob 8 is turned, one of the screw rods 5 and the sprocket 6 is driven to rotate, and then the other three sprockets 6 and the screw rods 5 are driven to rotate synchronously under the meshing action of the sprocket 6 and the chain 7, thereby avoiding the extrusion slide plate 4 from getting stuck during the horizontal movement.

[0028] like Figure 3 As shown, the limiting assembly includes a sliding shaft 9, in which a sliding hole is opened on the inner wall of the side of one of the sliding grooves, and the sliding shaft 9 is slidably installed in the sliding hole. An extrusion plate 10 is fixedly installed at one end of the sliding shaft 9, and the extrusion plate 10 is adapted to the screw 5. A compression unit is arranged on the side of the extrusion plate 10, and a pull ring 12 is fixedly installed at the other end of the sliding shaft 9. The advantage of such an arrangement is that, through the arrangement of the extrusion plate 10, the screw 5 can be limited by the extrusion effect to prevent it from rotating at will.

[0029] Specifically, when the control on the pull ring 12 is released, the compression unit drives the extrusion plate 10 to contact the screw 5, and the screw 5 is limited by the extrusion effect to prevent the screw 5 from rotating.

[0030] like Figure 3 As shown, the compression unit includes a compression spring 11, one end of the compression spring 11 is fixedly installed on the side of the extrusion plate 10, and the other end of the compression spring 11 is fixedly installed on the inner wall of the side of the slide groove. The advantage of this arrangement is that through the arrangement of the compression spring 11, the elastic action of the compression spring 11 can realize the resetting function of the extrusion plate 10, thereby improving the stability during limiting.

[0031] Specifically, when the control on the pull ring 12 is released, the squeezing effect on the compression spring 11 disappears synchronously, and the squeezing plate 10 is driven to achieve a reset function under the elastic effect of the compression spring 11, thereby improving the stability during the limiting period.

[0032] like Figure 3 As shown, the control unit includes two sliding plates 14, and two guide shafts 13 are fixedly installed on the relative inner walls of the rectangular sliding hole. The two sliding plates 14 are slidably installed on the two guide shafts 13 respectively, and the sides of the two sliding plates 14 are rotatably installed with connecting rods 16. The other ends of the two connecting rods 16 are rotatably installed on the sides of the two fixed plates 15 respectively, and the sides of the two sliding plates 14 are provided with reset elements. The advantage of such a setting is that, through the setting of the two sliding plates 14 and the two connecting rods 16, the extrusion effect of the extrusion slide plate 4 can be used to drive the two sliding plates 14 to move horizontally, thereby driving the two fixed plates 15 to move synchronously toward each other.

[0033] Specifically, when the extrusion slide plate 4 moves horizontally to a suitable position, the two sliding plates 14 are driven to move horizontally synchronously under the extrusion action thereof, and the two fixing plates 15 are driven to move toward each other synchronously under the connection action of the two connecting rods 16, thereby realizing the fixing function of the welding rod.

[0034] like Figure 3 As shown, the reset element includes a reset spring 17, which is sleeved on the guide shaft 13, one end of the reset spring 17 is fixedly mounted on the side of the sliding plate 14, and the other end of the reset spring 17 is fixedly mounted on the side inner wall of the rectangular sliding hole. The advantage of this arrangement is that, through the arrangement of the reset spring 17, when the extrusion slide plate 4 is reset, the elastic action of the reset spring 17 can drive the sliding plate 14 to achieve the reset function.

[0035] Specifically, when the squeezing slide plate 4 is in the reset motion, the squeezing effect on the sliding plate 14 disappears. At this time, the elastic effect of the reset spring 17 can drive the sliding plate 14, the connecting rod 16, and the fixed plate 15 to achieve the reset function.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
