However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these example embodiments are provided so that the description of the present disclosure will be more comprehensive and complete and the concepts of the example embodiments will be fully conveyed to those skilled in the art. The accompanying drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the figures represent the same or similar parts, and thus their repeated description will be omitted.

[0026] In addition, the described features, structures or characteristics may be combined in one or more example embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the example embodiments of the present disclosure. However, those skilled in the art will appreciate that the technical solutions of the present disclosure may be practiced while omitting one or more of the specific details, or other methods, components, steps, etc. may be adopted. In other cases, well-known structures, methods, implementations or operations are not shown or described in detail to avoid obscuring various aspects of the present disclosure.

[0027] The utility model provides a low-cost combined stage, the main purpose of which is to use an auxiliary support structure to adjust the position of steel pipes to be welded in advance, improve the accuracy of steel pipe welding, and reduce the high cost required for subsequent rework.

[0028] Example 1

[0029] like Figure 1-Figure 7 As shown, the utility model mainly includes a stage surface 1, steel pipes 2, connecting mechanisms 3 and stage scenery pieces 4. The bottom of the stage surface 1 is supported by criss-crossed steel pipes 2, and the steel pipes 2 are connected by connecting mechanisms 3. Several stage scenery pieces 4 are detachably placed on the stage surface 1 to achieve the purpose of creating stage atmosphere.

[0030] The connection mechanism 3 includes a clamp 31, a spiral coil 32 and a stud 33. The clamp 31 is generally used in pairs. The clamp 31 is used to be clamped on the steel pipe 2 and fixed to the steel pipe 2. One side of the clamp 31 is rotatably connected to the spiral coil 32, and the two spiral coils 32 are connected to each other through the stud 33. The two ends of the stud 33 are provided with threads with opposite rotation directions. When the two ends of the stud 33 are threadedly connected to the corresponding spiral coil 32, by rotating the stud 33, the clamp 31 can drive the corresponding steel pipe 2 to move closer or farther from each other, thereby achieving the purpose of adjusting the distance between the steel pipes 2.

[0031] Furthermore, the rotational connection relationship between the clamp 31 and the screw coil 32 can be adapted to the connection between the steel pipes 2 with welding angles, and even when the two clamps 31 are no longer coaxial, the two screw coils 32 can still be connected in series using the stud 33, thereby achieving the purpose of synchronously driving the two clamps 31 to drive the corresponding steel pipes 2 to move closer to or away from each other.

[0032] Furthermore, in addition to the method of connecting the two steel pipes 2 by welding, when the overall load-bearing capacity of the stage surface 1 is not high, the purpose of connecting the steel pipes 2 can also be achieved by fixing the clamp 31 and the screw ring 32 .

[0033] In addition, the spiral coil 32 includes a coil body 321 and a pipe 322. The coil body 321 is provided with a pipe 322 for connecting the inner and outer side walls of the coil body 321. The opening of the pipe 322 located on the inner side of the coil body 321 is provided in the thread. The number of openings on the outer side of the coil body 321 is smaller than the number of openings on the inner side of the coil body 321. In this way, the molten glue is poured into the pipe 322 from the outer opening of the coil body 321 through a hot melt gun, and flows out toward the opening on the inner side of the coil body 321 through the pipe 322, and is cooled and solidified in the thread between the coil body 321 and the stud 33, so as to achieve the purpose of fixing the stud 33 and the spiral coil 32, and prevent the stud 33 from resetting and rotating in the spiral coil 32, thereby achieving the purpose of limiting the relative position between the two spiral coils 32.

[0034] When it is necessary to remove the glue from the connection between the ring body 321 and the stud 33, current is passed through the resistance wire buried in the ring body 321, the resistance wire heats up and melts the glue. At this time, the stud 33 is rotated to allow the threaded surfaces of the stud 33 and the spiral ring 32 to rotate relative to each other. Then the power is removed and the stud 33 is kept rotating. This process lasts for about 5 seconds. At this time, because of the continuous rotation of the stud 33, not only can the stud 33 and the spiral ring 32 be separated from each other, but the relative movement of the two threaded surfaces can also be used to shear the cooled hot melt adhesive exposed to the inner side of the ring body 321, thereby achieving the purpose of cleaning up excess hot melt adhesive.

[0035] Preferably, the resistance wire is arranged inside the side wall of the pipe 322 so that the resistance wire can efficiently heat the hot melt adhesive inside the pipe 322 after being energized.

[0036] Example 2

[0037] like Figure 1-Figure 7On the basis of Example 1, a specific shape of the clamp 31 is set, and the clamp 31 includes a clamp body 311, a connecting belt 312 and a clamping block 313. The clamp body 311 and the spiral ring 32 are rotatably connected, one end of the clamp body 311 is fixedly connected to the connecting belt 312 and the other end is installed with a clamping block 313, the clamping block 313 includes a fixed block and a clip, the fixed block and the clamp body 311 are fixedly connected, the clip and the fixed block are elastically rotatably connected, a tooth mouth is fixed on the connecting belt 312, and the tooth mouth and the clip are engaged with each other. When in use, the connecting belt 312 is inserted into the gap between the fixing block and the clip, and the elastic force between the clip and the fixing block is used to automatically clamp it in the tooth mouth to fix the connecting belt 312. When disassembly is required, the clip is opened and the connecting belt 312 is pulled out.

[0038] Alternatively, the teeth of the connecting belt 312 can be equivalently replaced by pin holes, and the clamp block 313 can be correspondingly replaced by pins. When in use, the clamp 31 can wrap the steel pipe 2 by inserting the pins into the corresponding pin holes on the connecting belt 312. A plurality of pin holes are provided along the extending direction of the connecting belt 312.

[0039] Example 3

[0040] like Figure 1-Figure 7 On the basis of Example 1, the clamp 31 includes a clamp body 311 and a connecting belt 312. The clamp body 311 and the spiral ring 32 are fixedly connected, and several clamp bodies 311 and connecting belts 312 are staggeredly connected. The above-mentioned clamp 31 can be inserted from one end of the steel pipe 2 and moved to a specified position of the steel pipe 2.

[0041] Furthermore, the hoop body 311 is a retractable structure, that is, the connecting belt 312 is an elastic cloth; or the hoop body 311 and the connecting belt 312 are elastically slidably connected, and the material of the connecting belt 312 is relatively hard, which is convenient for guiding the sliding of the hoop body 311.

[0042] On the basis of Embodiment 2 and Embodiment 3, an anti-slip sheet is fixed on the inner wall of the hoop body 311 to prevent the position of the clamp 31 from accidentally moving after clamping the steel pipe 2 .

[0043] In contrast, the connecting belt 312 and the hoop body 311 of Example 2 are detachable, which makes it easy to connect to the steel pipe 2 from the middle position of the steel pipe 2. Example 3 is of a sleeve-type and can only be inserted from one end of the steel pipe 2 and moved to a suitable position.

[0044] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
