[0030] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0031] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solutions of this utility model are further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0032] In the description of this utility model, it should be noted that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are only for illustrative purposes to aid those skilled in the art and to facilitate understanding and reading. They are not intended to limit the implementation conditions of this utility model and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to the size, without affecting the effects and objectives of this utility model, should still fall within the scope of the technical content disclosed in this utility model. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of implementation of this utility model.

[0033] like Figure 1-5 As shown in the figure, this utility model embodiment proposes a corrugated pipe protection device for steel bar welding, including a main protective plate 10, a side protective plate 20, and a snap-fit ​​member 30; the main protective plate 10 is provided with a hand-held member 50; the side protective plate 20 is slidably inserted through one side of the main protective plate 10 in a left-right direction; the snap-fit ​​member 30 is slidably disposed in the corresponding hole of the main protective plate 10, and is snapped or separated from the side protective plate 20 to limit or release the limitation of the side protective plate 20.

[0034] In this embodiment of the invention, during use, the main protective plate 10 can be easily moved using the handheld component 50. The main protective plate 10 is placed outside the corrugated pipe welding area, covering the portion requiring protection to prevent the corrugated pipe from being easily affected by welding sparks and high-temperature slag during rebar welding. Secondly, the position of the side protective plate 20 can be adjusted according to the range of the corrugated pipe welding area using the snap-fit ​​component 30, allowing it to slide left and right to a suitable position to completely cover the welding area. Specifically, by pushing the snap-fit ​​component 30, it snaps into the hole of the main protective plate 10, forming a snap-fit ​​with the side protective plate 20, locking its position and preventing the side protective plate 20 from sliding. This allows workers to safely perform rebar welding under the protection of the device, avoiding damage to the corrugated pipe from sparks or high-temperature slag. After welding is completed, the snap-fit ​​component 30 is released, separating it from the side protective plate 20, allowing the side protective plate 20 to slide and retract for easy storage and future use.

[0035] It is important to know that, such as Figure 1-2 As shown in this embodiment of the utility model, there are two side guard plates 20, which are symmetrically arranged on both sides of the main guard plate 10. There are also two corresponding snap-fit ​​parts 30, which correspond to the two side guard plates 20 respectively. The two side guard plates 20 can provide a larger protection range. Specifically, workers can use only the main guard plate 10 for protection, or they can use the main guard plate 10 plus the left or right side guard plate 20 for protection, or they can open both side guard plates 20 to cooperate with the main guard plate 10 for protection. This realizes the adjustment of various range sizes and makes it more applicable.

[0036] Specifically, such as Figure 3-5 As shown in this embodiment of the present invention, the snap-fit ​​component 30 includes a pressing post 31, the main guard plate 10 has an installation groove 11, the pressing post 31 is slidably disposed in the installation groove 11, the side guard plate 20 has a slot 21, and one side of the slot 21 has an opening 22, the pressing post 31 is adapted to the opening 22, the pressing post 31 has a locking block 32 adapted to the slot 21, the installation groove 11 is provided with a spring piece 33, and the spring piece 33 is connected to the inner top end of the locking block 32.

[0037] In the initial state, the locking block 32 is always engaged with the slot 21 under the action of the spring piece 33. When the pressing post 31 is pressed down until the locking block 32 separates from the slot 21, the side guard plate 20 is released and can be moved and pulled out. At the same time, since the slot 21 has an opening 22, the side guard plate 20 will pass through the pressing post 31 when pulled out without being blocked. Conversely, when it is necessary to store the side guard plate 20 into the main guard plate 10, the pressing post 31 is pressed down so that the opening 22 on the side guard plate 20 passes through the pressing post 31. At this time, the spring piece 33 in the mounting groove 11 provides elasticity, so that the pressing post 31 rebounds after being released, causing the locking block 32 to engage with the slot 21, restricting the movement of the side guard plate 20 and improving stability. In addition, for the convenience of personnel operation, the top of the pressing post 31 is provided with several anti-slip grooves.

[0038] Secondly, such as Figure 4-5 As shown, the main guard plate 10 is provided with a fixing groove 12 along the sliding direction of the side guard plate 20. A spring 40 is provided in the fixing groove 12. The spring 40 is connected to the inner top of the side guard plate 20. The spring 40 enables the side guard plate 20 to automatically extend out of the main guard plate 10 after the limiting of the snap fastener 30 is released, so as to facilitate unfolding and use.

[0039] Again, such as Figure 5 As shown, the side guard plate 20 is provided with a limiting protrusion 23 along its sliding direction, and the main guard plate 10 is provided with a limiting groove 13 that matches the limiting protrusion 23. The limiting protrusion 23 is slidably disposed in the limiting groove 13 so that the sliding process of the side guard plate 20 is more stable and smooth.

[0040] Based on the above solutions, such as Figure 1-2 As shown in the embodiment of this utility model, the cross-section of the main guard plate 10 and the side guard plate 20 is an arc shape that matches the shape of the corrugated pipe. The arc shape can better fit the corrugated pipe, improve stability, and prevent positional displacement during welding.

[0041] Specifically, such as Figure 1-2 As shown in this embodiment of the invention, the handheld component 50 includes a first handle 51 rotatably connected to the main guard plate 10 and a second handle 52 detachably connected to the first handle 51. The rotatable connection allows the handheld component 50 to be adjusted in angle to adapt to different usage needs. The detachable design of the second handle 52 reduces the size of the device when not in use, making it easier to store and carry.

[0042] Specifically, the first handle 51 and the second handle 52 are connected by a connector 53. Both the first handle 51 and the second handle 52 are threaded and are fixed to the connector 53 by the threaded connection to achieve the extension and shortening of the length. The tail end of the second handle 52 is provided with a handle 54, which is provided with a hanging hole for hanging and storage, so as to facilitate quick access when the second handle 52 is not disassembled.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
