[0033] See also Figure 1-5 The utility model provides a technical solution: a fixed anti-splash blasting fixing device, including a chassis 10, a sleeve 20, a screw rod 201, a pointed cone 202, a horizontal plate 30, a positioning plate 301, a horizontal plate 40, a positioning plate 401, a rotating drum 50, a screw rod 501, a gasket 502, a limit block 503, a telescopic rod 504, a limit block 505, a shock-absorbing rubber 60, a silicone pad 601, an arc plate 602, an arc plate 603, a shock-absorbing rubber 604 and a silicone pad 605;

[0034] The blasting fixing device fixes the explosive pack, and the specific implementation method is as follows:

[0035] The chassis 10 is set as a square plate-shaped structure, and a sleeve 20 is installed on the surface of the chassis 10; a screw rod 201 is embedded in one side surface of the sleeve 20, and a pointed cone 202 is fixedly connected to the bottom surface of the chassis 10. The end of the screw rod 201 is fixedly connected to a horizontal plate 30, and one end of the horizontal plate 30 is fixedly connected to a positioning plate 301, and two horizontal plates 30 are symmetrically set on the surface of the positioning plate 301. The surfaces of the two horizontal plates 30 are both embedded. There is a horizontal plate 40, and the end of the horizontal plate 40 passes through the surface of the horizontal plate 30 and is connected to the positioning plate 401. The interior of the positioning plate 401 is provided with a fixing mechanism, and the fixing mechanism includes: a rotating drum 50 is rotatably installed on the surface of the positioning plate 401, and a screw rod 501 is embedded in the interior of the rotating drum 50. The end of the screw rod 501 passes through the surface of the positioning plate 401 and is connected to a gasket 502. The end of the gasket 502 is fixedly connected to a limiting block 503, and the limiting block The surface of the first 503 is fixedly connected with a telescopic rod 504, the interior of the positioning plate 301 is embedded with a sliding installation limit block 2 505, and the surface of the limit block 2 505 is connected with the telescopic rod 504, the interior of the sleeve 20 is provided with a thread, and the sleeve 20 and the screw rod 201 are threadedly connected, the horizontal plate 1 30 and the horizontal plate 2 40 are slidably connected, and the ends of the two horizontal plates 2 40 are correspondingly set, the positioning plate 301 is set as a hollow structure, and the limit block 1 503 is set Inside the positioning plate 1 301, the outer side of the limit block 1 503 fits against the inner wall of the positioning plate 1 301, and the limit block 1 503 and the positioning plate 1 301 are slidably connected. A cavity is embedded in the surface of the positioning plate 2 401, and the limit block 2 505 is arranged inside the cavity of the positioning plate 2 401, and the limit block 2 505 and the positioning plate 2 401 are slidably connected. A thread is provided inside the rotating drum 50, and the rotating drum 50 is threadedly connected to the screw rod 2 501.

[0036] When the length of the explosive pack is reached, the positioning plate 2 401 is pulled outward, and the positioning plate 2 401 drives the horizontal plate 2 40 to move, so that the horizontal plate 2 40 slides outward on the surface of the horizontal plate 1 30. At this time, the telescopic rod 504 is extended. When the horizontal plate 1 30 and the horizontal plate 2 40 are pulled to a suitable length, the positioning plate 2 401 is stopped, and the explosive pack passes through the hollow of the positioning plate 2 401, so that the end of the explosive pack is placed inside the cavity of the positioning plate 1 301. At this time, the bottom of the explosive pack falls on the surface of the horizontal plate 2 40 on the horizontal plate 1 30. At this time, the other side of the explosive pack is placed inside the positioning plate 2 401. The screw rod 2 501 is rotated downward by hand, so that the screw rod 2 501 moves downward along the thread inside the rotating drum 50. At this time, the screw rod 2 501 pushes the gasket 502 to move downward, and the gasket 502 drives the limit block 1 503 to move downward inside the positioning plate 2 401, so that the end of the limit block 1 503 contacts the surface of the explosive pack. When the explosive pack is fixed in the inner part of the limit block 503 and the positioning plate 2 401, one side of the explosive pack can be fixed at this time. When the limit block 1 503 moves, the limit block 1 503 drives the limit block 2 505 to move downward through the telescopic rod 504, so that the bottom of the limit block 2 505 fits the surface of the explosive pack, and the other side of the explosive pack is fixed to fix the explosive pack inside the device. At this time, the device can be placed on the installation surface, so that the bottom of the chassis 10 fits the installation surface, and the device is pressed downward. At this time, the chassis 10 drives the pointed cone 202 to move downward, so that the end of the pointed cone 202 is inserted into the inner part of the installation surface to fix the position of the device. At this time, the hand-held horizontal plate 2 40 rotates on the horizontal plate 1 30, and the horizontal plate 2 40 drives the screw rod 1 201 to rotate on the horizontal plate 1 30, so that the screw rod 1 201 rotates inside the sleeve 20. When the explosive rotates to the appropriate position, the rotation of the horizontal plate 2 40 stops and the horizontal plate 1 30 is fixed to the horizontal plate 1.

[0037] The blasting fixing device reduces the splashing of explosive bag debris, and the specific implementation method is as follows:

[0039] When the horizontal plate 2 40 slides outward on the surface of the horizontal plate 1 30, the horizontal plate 2 40 drives the arc plate 2 603 to move outward, so that the arc plate 2 603 moves outward inside the arc plate 1 602, and the explosive package is blocked by the arc plate 1 602 and the arc plate 2 603. When the limit block 1 503 moves downward through the telescopic rod 504, the telescopic rod 504 pushes the silicone pad 2 605 and the silicone pad 1 601 to move downward, so that the bottom of the silicone pad 2 605 and the silicone pad 1 601 fits with the surface of the explosive package. When the explosive package explodes, the arc plate 2 603 and the arc plate 1 603 are in contact with each other. The curved plate 1 602 blocks the debris of the explosive package to prevent it from splashing, and transmits the thrust to the surfaces of the silicone pad 2 605 and the silicone pad 1 601. The silicone pad 2 605 transmits the thrust to the shock-absorbing rubber 2 604. At the same time, the shock-absorbing rubber 2 604 transmits the thrust to the surfaces of the curved plate 1 602 and the curved plate 2 603. The silicone pad 1 601 transmits the thrust to the shock-absorbing rubber 1 60, and the shock-absorbing rubber 1 60 transmits the thrust to the surface of the horizontal plate 2 40 on the horizontal plate 1 30. At this time, the thrust is dispersed and the vibration is transmitted to different positions to prevent the device from being damaged and broken.

[0040] Working principle: When using the fixed anti-splash blasting fixture, a limit block 503, a telescopic rod 504 and a limit block 505 are set to fix the explosive package, and an arc plate 602, an arc plate 603, a shock-absorbing rubber 604 and a silicone pad 605 are set to reduce the splash of explosive package debris and increase the overall practicality.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
