DETAILED DESCRIPTION

[0019] In order to make the above-mentioned purpose, features and advantages of the utility model more apparent, obvious, the specific implementation of the utility model is explained in detail below with the accompanying drawings.

[0020] Secondly, the utility model is described in detail in conjunction with the schematic diagram, and when the utility model implementation is in detail, for easy to illustrate, the section view of the device structure will be partially enlarged without the general proportion, and the schematic diagram is only an example, which should not limit the scope of the utility model protection here. In addition, the three-dimensional spatial dimension of length, width and depth should be contained in actual production.

[0021] In order to make the purpose, technical scheme and advantage of the utility model more clear, the implementation of the utility model will be further described in detail below in conjunction with the drawings.

[0022] Please refer to Figs. 1-3 The utility model provides a punching device of anti -theft door, including hydraulic rod 1, both sides of hydraulic rod 1 top are fixedly connected with mounting bracket 4, and mounting bracket 4 end part is equipped with mounting screw hole, is convenient for the positioning of the connection of hydraulic rod 1 and external fixed support.

[0023] The bottom of the telescopic end of the hydraulic rod 1 is fixedly connected with the adapter 2, the bottom of the adapter 2 is provided with the punch 3, the bottom of the adapter 2 is fixedly connected with the hexagonal prism 201, the top of the punch 3 is fixedly connected with the connector 5, the hexagonal groove 501 is formed in the connector 5, the hexagonal groove 501 is correspondingly inserted with the hexagonal prism 201, and the adapter 2 and the connector 5 are threadedly connected with the locking ring 6 on the outer wall, so as to conveniently connect and fix the punch 3 with the telescopic end of the hydraulic rod 1.

[0024] The punch 3 is internally provided with the mounting groove 7, the electromagnet 8 is fixedly connected to the top of the mounting groove 7, the movable rod 9 is slidably connected to the inside of the mounting groove 7, the magnet main body 10 is fixedly connected to the top of the movable rod 9, the magnet main body 10 is correspondingly magnetized with the electromagnet 8, in the initial state, the electromagnet 8 is electrified and attracted to the magnet main body 10, and when punching, the electrification direction of the electromagnet 8 is changed, and repulsion is generated between the electromagnet 8 and the magnet main body 10.

[0025] A slot 15 is provided at the bottom of the mounting groove 7 , and the bottom of the movable rod 9 fits in the slot 15 . The outer wall of the movable rod 9 fits in with the outer walls of the two movable blocks 12 , so as to limit the movable position of the movable rod 9 .

[0026] Slide grooves 11 are provided on both sides of the inner wall of the installation groove 7, and a movable block 12 is slidably connected inside the slide groove 11. A slider 13 is fixedly connected to the side of the movable block 12 close to the movable rod 9, and slide rails 14 corresponding to the slider 13 are provided on both sides of the outer wall of the movable rod 9.

[0027] In this embodiment, the end of the slider 13 is connected to a ball joint, and the ball is located inside the slide rail 14 and fits with its inner wall. When the movable rod 9 moves up and down, the ball rolls accordingly in the slide rail 14, making it easier for the movable block 12 to adapt to the position change of the movable rod 9.

[0028] When in use, the hydraulic rod 1 is installed on an external fixed bracket and connected to the external oil pump, the electromagnet 8 is energized and attracted to the magnet body 10. In the initial state, the movable rod 9 is located at the top position of the mounting groove 7, and the slider 13 at the end of the movable block 12 is restricted by the slide rail 14 on the outer wall of the movable rod 9, so that the movable block 12 is retracted into the slide groove 11.

[0029] When drilling, the anti-theft door to be drilled is placed under the drilling drill 3, and the drilling drill 3 is driven down by the hydraulic rod 1 to drill holes in the anti-theft door.

[0030] After the punch drill 3 drills into the anti-theft door, the current direction of the electromagnet 8 is changed, and the magnetic poles of the electromagnet 8 are changed so that it repels the magnet body 10. At this time, the movable rod 9 slides down under the action of the repulsive force. At this time, the slider 13 at the end of the movable block 12 slides in the slide rail 14 on the outer wall of the movable rod 9, and gradually pushes the movable block 12 out of the outer wall of the punch drill 3.

[0031] Then the hydraulic rod 1 is started again to drive the punch drill 3 to rise and retract. During the retraction process, the movable blocks 12 extending from both sides of the punch drill 3 are used to push back the concave door panel around the hole. When the periphery of the hole is pushed out and leveled, the magnetic poles of the electromagnet 8 are changed again to retract the movable block 12 into the inside of the punch drill 3, and the punch drill 3 can be pulled out of the hole.

[0032] Although the utility model has been described above with reference to the embodiments, various modifications can be made thereto, and equivalent replacements can be made to the components thereof, without departing from the scope of the utility model.
