Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of detonating switches, in particular to a disposable electronic selective firing module detonating switch. Background Art
[0002] A disposable electronic selective module detonating switch refers to a special type of detonating switch used in the blasting industry. It is usually used for one-time blasting operations. Once used, this detonating switch usually cannot be used again. Currently, detonating switches usually have two types: box type and handheld type. The box type detonating switch is inconvenient to carry, while the handheld type is easy to carry and can be used in areas where it is difficult to walk.
[0003] Compared with box-type detonating switches, handheld detonating switches are less stable and safe. Their switch parts are usually blocked by only a shield. If the shield is accidentally opened during movement, the switch may be accidentally touched, resulting in safety hazards. In addition, when walking in difficult-to-walk areas, operators need to pull the wires, which may cause the wires to detach from the detonating switches, resulting in poor contact of the detonating switches. Poor contact may cause poor or interrupted current transmission, resulting in the inability of the detonating device to trigger the explosion on time, delaying the explosion time or causing the explosion to be ineffective. This will increase the risk of explosion safety, unpredictable explosion effects and the possibility of equipment failure, and will also affect work efficiency. Utility Model Content

A placing ring 14 is fixedly installed at the rear end of the shell 1, and a wire 15 is clamped inside the placing ring 14. A fixing ring 16 is fixedly installed at the rear end of the shell 1, and a slider 17 is slidably connected inside the fixing ring 16. The end of the slider 17 close to the placing ring 14 is rotatably connected to a telescopic rod 18, and the end of the telescopic rod 18 away from the slider 17 is rotatably connected to an abutting rod 19. A bent rod 20 is fixedly installed on the surface of the slider 17, and a rotating plate 21 is rotatably connected to the surface of the bent rod 20.
[0023] As an optimization, a switch is provided at the front end of the housing 1. The switch is located inside the protective plate 2. The protective plate 2 protects the switch. The wire 15 is electrically connected to the switch. After the switch is powered on, the switch can be pulled to perform the detonation operation.
[0024] As an optimization, the clamping block 6 and the clamping slot 3 are adapted and clamped, and the clamping rod 13 and the limiting slot 4 are adapted and clamped, so that the protection plate 2 is limited, thereby increasing the reliability of the switch protection.
[0025] As an optimization, the cross-sectional shape of the inner groove 7 is a cross shape, and the inner groove 7 runs through the upper and lower and front and rear ends of the block 6.
[0026] As an optimization, the pressing rod 11 is slidably connected inside the inner groove 7 and passes through the block 6 and is located at the rear end of the inner groove 7 . The two clamping rods 13 pass through the block 6 and are located at the upper and lower sides of the inner groove 7 .
[0027] As an optimization, the end of the push rod 12 away from the sliding rod 10 is rotatably connected to the end of the clamping rod 13 close to the center of the clamping block 6. When the sliding rod 10 moves, it pushes the push rod 12. At this time, the push rod 12 pushes the clamping rod 13 to clamp inside the limiting groove 4 to limit the position of the protective plate 2.
[0028] As an optimization, the abutment rod 19 and the wire 15 are adapted to be clamped, there are four sliders 17 and bent rods 20 and they are fixedly connected in sequence and staggered, and the end of the rotating plate 21 away from the bent rod 20 is adapted to abut against the inside of the fixed ring 16, and the rotating plate 21 abuts against the inside of the fixed ring 16 so that the slider 17 and the bent rod 20 are confined inside the fixed ring 16.
[0029] Working principle: when in use, the operator rotates the protection plate 2 so that its bottom end abuts against the surface of the housing 1. At this time, the protection plate 2 shields and protects the switch. At the same time, when the bottom end of the protection plate 2 abuts against the surface of the housing 1, the inner wall of the card slot 3 contacts the front end of the card block 6. The card block 6 is clamped in the inside of the card slot 3. In this process, the inner wall of the card slot 3 pushes the driven block 8, so that the driven block 8 moves to the inside of the inner groove 7. During the movement of the driven block 8, the spring 9 is compressed. When the elastic force accumulated after the spring 9 is compressed is greater than the friction between the pressing rod 11 and the inner wall of the inner groove 7, the spring 9 pushes the sliding rod 10 and the pressing rod 11. The rod 11 moves toward the front end of the shell 1 until the pressing rod 11 is separated from the inner groove 7. During the movement of the sliding rod 10, the sliding rod 10 gradually approaches the card rod 13. At this time, the sliding rod 10 pushes the push rod 12 to rotate, so that the push rod 12 pushes the card rod 13 to move to the outside of the block 6. When the end of the card rod 13 away from the push rod 12 is separated from the inner groove 7 and moves to the outside of the block 6, the card rod 13 moves to the inside of the limit groove 4. The card rod 13 further limits the position of the protective plate 2 to prevent the protective plate 2 from separating from the shell 1 during the movement. At this time, the protective plate 2 stably blocks and protects the switch.
[0030] After the operator inserts the wire 15 into the placement ring 14 and energizes the protection plate 2, the operator rotates the slider 17 and the bent rod 20. During the rotation of the bent rod 20, the bent rod 20 will continue to approach the abutment rod 19. At this time, the bent rod 20 will compress the telescopic rod 18 and push the abutment rod 19 to move toward the direction close to the outer skin of the wire 15 until the abutment rod 19 abuts against the outer skin of the wire 15. At this time, multiple abutment rods 19 limit the wire 15. Then the operator rotates the rotating plate 21 to make it abut against the inside of the fixed ring 16. At this time, the slider 17 and the bent rod 20 cannot continue to rotate, that is, the position of the abutment rod 19 is limited, so that the abutment rod 19 is more stable in limiting the wire 15. Then, when the operator moves in a rugged area, the wire 15 will not separate from the placement ring 14 and cause poor contact.
