[0028] 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.
[0029] Refer to 1. Figure 2 The utility model provides an embodiment: a protective barrier for earthwork blasting, comprising a baffle 1, which is a protective plate, used to block the surrounding for protection during earthwork blasting to prevent splashing earth and rocks from injuring workers. The front and rear sides of the baffle 1 are both provided with brackets 2, which support the baffle 1, and a connecting component 5 is provided inside the baffle 1, which is used to connect the baffle 1 and the baffle 2 4. The right side of the connecting component 5 is provided with the baffle 2 4. The baffle 2 4 is the same as the baffle 1, and both of them are protective fences for protection. The front and rear sides of the baffle 2 4 are both provided with supporting components 3, which are used to support the baffle 2 4. The connecting component 5 comprises a U-shaped block 51, which is slidably connected to the inner wall of the baffle 1, and fixed blocks are provided at the front and rear ends of the U-shaped block 51. When sliding to the rightmost side close to the baffle 1, it cannot continue to slide to prevent falling off. The bottom end of the U-shaped block 51 is penetrated and rotatably connected with a round rod 53.
[0030] Reference Figure 2 - Figure 4The connecting assembly 5 also includes a circular sleeve 54, which is fixedly connected to the bottom end of the U-shaped block 51. The outer wall of the U-shaped block 51 is fixedly connected with a circular shell 56, and the inner wall of the circular shell 56 is slidably connected with a supporting ball 58. The supporting ball 58 and the circular shell 56 are elastically connected by a spring 57, and the circular shell 56 and the supporting ball 58 are connected by the spring 57, and the reverse force of the spring 57 makes the supporting ball 58 reset and rebound into the limiting groove 55 to play a supporting role, thereby increasing the working stability of the baffle 1 and the baffle 2 4. One end of the spring 57 is fixedly connected to the inner wall of the circular shell 56, and the other end of the spring 57 is fixedly connected to the left side of the supporting ball 58. The inner wall of the circular sleeve 54 is provided with a plurality of limiting grooves 55, and the limiting grooves 55 are adapted to the supporting balls 58, and the supporting balls 58 will only contact half of the limiting grooves 55, and will not be stuck in the limiting grooves 55, but only play a supporting role.
[0031] Reference Figure 1 , Figure 2 The right side of the round rod 53 is fixedly connected with a connecting rod 52, and two groups of U-shaped blocks 51 and round rods 53 are provided, and the two groups of U-shaped blocks 51 and round rods 53 are symmetrically arranged with the center line of the connecting rod 52 as the symmetry axis. The length of another round rod 53 is shorter than the first round rod 53, and the right side of the other U-shaped block 51 is fixedly connected to the left side of the baffle 2 4.
[0032] Reference Figure 1 , Figure 5 The support assembly 3 includes a rotating shaft 31, which is rotatably connected to the inner wall of the front surface of the baffle plate 4, and the outer wall of the rotating shaft 31 is fixedly connected to a support plate 36, and the inner wall of the bottom end of the support plate 36 is slidably connected to an extension plate 35, and the extension plate 35 and the support plate 36 are elastically connected by a spring 2 34, and the spring 2 34 supports the extension plate 35 and the support plate 36, and the reverse force of the spring 2 34 makes the extension plate 35 extend out to contact the ground to provide a certain support to the baffle plate 4, one end of the spring 2 34 is fixedly connected to the inner wall of the bottom end of the support plate 36, when the baffle plate 4 is in the baffle 1, the spring 2 34 is in a compressed state, and the other end of the spring 2 34 is fixedly connected to the top of the extension plate 35.
[0033] Reference Figure 1 , Figure 5The inner wall of the front surface of baffle plate 2 4 is fixedly connected with a circular ring block 33, and the circular ring block 33 and the rotating shaft 31 are elastically connected by a torsion spring 32. The reverse force of the torsion spring 32 causes the support plate 36 to expand outward. When baffle plate 2 4 is in baffle plate 1 1, the torsion spring 32 is in a compressed state, and when the top end of the support plate 36 rotates and contacts the inner wall of baffle plate 2 4, it cannot continue to rotate and will only rotate to a certain inclination angle so that it can be supported normally. One end of the torsion spring 32 is fixedly connected to the outer wall of the rotating shaft 31, and the other end of the torsion spring 32 is fixedly connected to the inner wall of the circular ring block 33, and the bottom end of the extension plate 35 is set as an inclined surface.
[0034] Working principle: When in use, first move the device to the location where work is required, and then pull the baffle plate 2 4 to the right. When the baffle plate 2 4 moves, it will drive the U-shaped block 51 to move together. When the U-shaped block 51 moves to the rightmost side of the baffle plate 1, it cannot continue to move to the right. At this time, the support plate 36 opens outwards due to the pressure released by the torsion spring 32, and the extended plate 35 moves downward to contact the ground for support due to the compressed pressure of the spring 2 34. At this time, the work of increasing the protection area is completed;
[0035] When the protection angle needs to be adjusted, the baffle plate 2 4 is first rotated. When the baffle plate 2 4 rotates, the U-shaped block 51 on the left side of the baffle plate 2 4 is driven to rotate together, and the U-shaped block 51 drives the connecting rod 52 to rotate together, and the connecting rod 52 drives the round rod 53 to rotate, and the round rod 53 drives the round shell 56 to rotate. When the round shell 56 rotates, the supporting ball 58 will slide out of the limiting groove 55 and will be pressed to move backward to squeeze the spring 1 57. When the supporting ball 58 contacts another limiting groove 55, the reverse force of the spring 1 57 causes it to bounce into the limiting groove 55 and produce a sense of frustration, which plays a stabilizing role. When the baffle plate 24 needs to be retracted, the baffle plate 24 is first reset to the same horizontal plane as the baffle plate 1, and the two support plates 36 are retracted inwardly. When the support plates 36 are retracted inwardly, since the bottom end of the extension plate 35 is set as an inclined surface, when the support plates 36 are retracted inwardly, the bottom surface of the extension plate 35 will be pressurized, causing the extension plate 35 to move upward and compress the spring 2 34. When the support plate 36 is retracted to overlap with the baffle plate 24, the baffle plate 24 is moved to the left, so that the baffle plate 24 slides into the baffle plate 1 to complete the storage work.
[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. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
