[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figures 1-3 This utility model provides an embodiment of a protective structure for a blasting warning device, comprising a support frame 1, a protective cover 2 slidably connected to the outer wall of the support frame 1, a slot 8 provided inside the support frame 1, a sliding rod 3 fixedly connected inside the protective cover 2, the outer wall of the sliding rod 3 slidably connected to the inside of the support frame 1, a locking post 7 fixedly connected inside the sliding rod 3, the outer wall of the locking post 7 rotatably connected to the inner wall of the slot 8, one end of a first spring 4 fixedly connected to the outer wall of the sliding rod 3, the other end of the first spring 4 fixedly connected to a placement block 9, the outer wall of the placement block 9 fixedly connected to the outer wall of the protective cover 2, the inner wall of the placement block 9 slidably connected to the outer wall of the sliding rod 3, a fixing post 5 slidably connected inside the placement block 9, the outer wall of the fixing post 5 fixedly connected to the outer wall of the sliding rod 3, a handle 6 fixedly connected to the outer wall of the fixing post 5, a horn 10 fixedly connected to the upper surface of the support frame 1, and a support assembly provided on the lower surface of the support frame 1 for auxiliary fixation.

[0024] Specifically, pressing and rotating handle 6 causes the fixed column 5 and slide rod 3 to slide on the inner wall of the storage block 9, and also causes the slide rod 3 to slide inside the support frame 1. The first spring 4 is squeezed by the force of the fixed column 5, and during the rotation, it causes the locking column 7 to be locked on the inner wall of the slot 8 and fixed inside the support frame 1, thus fixing the protective cover 2 and the support frame 1, protecting the speaker 10, and achieving the effect of quick installation.

[0025] Reference Figure 1 The support assembly includes a base 11, the outer wall of which is fixedly connected to the lower surface of the support frame 1, and a support seat 12 is fixedly connected to the lower surface of the base 11.

[0026] Specifically, the base 11 supports the support frame 1, and the support seat 12 fixes the base 11, thus providing stable support.

[0027] Reference Figure 4 A hinge 13 is fixedly connected to the outer wall of the support base 12. A fixing plate 14 is fixedly connected to the outer wall of the hinge 13. A fixing shaft 15 is rotatably connected to the outer wall of the fixing plate 14. A shaped block 16 is fixedly connected to the outer wall of the fixing shaft 15. A connecting column 17 is fixedly connected to the outer wall of the shaped block 16. A second spring 18 is fixedly connected to the outer wall of the connecting column 17. A first support column 19 is fixedly connected to the outer wall of the second spring 18. The outer wall of the first support column 19 is fixedly connected to the outer wall of the fixing plate 14. A connecting plate 20 is fixedly connected to the outer wall of the hinge 13. The upper surface of the connecting plate 20 is in contact with the lower surface of the fixing plate 14. A connecting rod 22 is fixedly connected inside both the connecting plate 20 and the fixing plate 14. A second support column 21 is fixedly connected to the outer wall of the connecting plate 20. The outer wall of the second support column 21 is in contact with the outer wall of the shaped block 16. A wheel 23 is fixedly connected to the lower surface of the connecting plate 20.

[0028] Specifically, pushing the irregularly shaped block 16 causes it to rotate on the outer wall of the fixed plate 14 via the fixed shaft 15, which allows it to detach from the second support column 21. This causes the second spring 18 to extend and retract between the connecting column 17 and the first support column 19. The hinge 13 then rotates the fixed plate 14 and the connecting plate 20, bringing the support base 12 into contact with the ground and providing stable support for the warning device. Pressing down on the fixed plate 14 can lock the irregularly shaped block 16 onto the lower surface of the second support column 21 and cause the support base 12 to detach from the ground. At this point, the wheel 23 can be used to move the device, making it easy to move.

[0029] Working principle: When this structure is needed, the wheel 23 allows the device to be pushed to the required position. Pushing the irregularly shaped block 16 to the left causes it to rotate on the outer wall of the fixed plate 14 via the fixed shaft 15, allowing it to slide off the outer wall of the second support column 21. This, in turn, pulls the second spring 18 via the connecting column 17, causing the fixed plate 14 and connecting plate 20 to rotate via the hinge 13, bringing the support base 12 into contact with the ground and providing stable support for the warning device. When movement is required, pressing the fixed plate 14 downwards causes the irregularly shaped block 16 to press against the second support column 21 on the outer wall of the connecting plate 20, thus securing the irregularly shaped block 16 to the second support column. The lower surface of 21 is pushed, and the support base 12 is lifted off the ground. At this time, the device can be pushed to achieve the effect of easy movement. The protective cover 2 is pushed to slide on the outer wall of the support frame 1. At this time, the handle 6 is pressed and rotated. The handle 6 will drive the fixing column 5 to slide on the inner wall of the block 9. The fixing column 5 will squeeze the first spring 4, and drive the slide rod 3 to slide inside the support frame 1. During the rotation, the locking column 7 will be locked on the inner wall of the locking groove 8, thereby fixing it inside the support frame 1. The protective cover 2 can be quickly installed on the outer wall of the support frame 1 to protect the speaker 10. This structure can not only achieve the effect of easy movement, but also achieve the effect of quick installation of the protective cover 2.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
