Description

Technical Field

[0001] The utility model relates to the technical field of detonator initiators, in particular to a detonator initiation device. Background Art

[0002] A detonator initiation device is a device used to detonate explosives. It usually consists of an electronic trigger and one or more detonators. A detonator is a very sensitive device that can be remotely or timed activated by an electrical signal or other means to detonate explosives, and is commonly used in engineering blasting, mine blasting, and military applications.

[0003] For example, in the Chinese patent with the application number 202222839928.1, a detonator initiator that is convenient for maintenance is provided. Each control button on the top of the detonator initiator body can be separately covered by a protective cover. When the box cover is opened, the protection of the buttons can be strengthened. When the corresponding button needs to be operated, only the corresponding protective cover needs to be opened for operation, avoiding the possibility of accidentally touching other buttons.

[0004] However, this type of detonator initiator uses a flip cover for protection. However, in sunny weather, since the detonator initiator needs to be wired, the box cover needs to be opened. In this way, the electronic components inside the detonator initiator will be exposed to strong sunlight, and the flip cover cannot block the sunlight, resulting in possible damage to the electronic components inside the detonator initiator due to overheating under long-term exposure to the sun.

[0005] Therefore, in view of this problem, the utility model provides a detonator initiation device. Summary of the Utility Model

[0006] The purpose of the utility model is to solve the problem in the prior art that the flip cover cannot block sunlight, resulting in possible damage to the electronic components inside the detonator initiator due to overheating under long-term exposure to the sun, and to propose a detonator initiation device.

[0007] To achieve the above purpose, the utility model adopts the following technical scheme:

[0008] A detonator initiation device includes an initiator housing. A top cover is embedded and installed at the top of the initiator housing. An installation shell is fixed to the side of the initiator housing. One end of a rotating rod one is rotatably mounted on the inner wall of the installation shell through a bearing. A circular gear is fixed to the end of the rotating rod one located inside the installation shell. A knob is fixed to the end of the rotating rod one away from the circular gear. A rack is fixed to the bottom of the top cover. The rack is meshed and connected with the circular gear. A limiting mechanism for limiting the knob is arranged on the installation shell. The installation shell is also provided with a supporting mechanism for supporting the initiator housing.

[0009] Preferably, a fixing block is fixed on one side of the detonator housing away from the mounting shell, a lifting strip is fixed at the bottom of the top cover, and the lifting strip is slidably connected to the fixing block.

[0010] Preferably, the limiting mechanism includes two rectangular blocks symmetrically fixed on the outer surface of the mounting shell. A lifting rod is slidably arranged in the middle of each rectangular block. One end of each lifting rod is fixed with an arc-shaped block. A limiting rod is fixed at the top of the arc-shaped block, and the limiting rod is slidably connected to the rectangular block. The top end of the lifting rod is fixed with a groove block, and fixing teeth are fixed on the outer surface of the knob, and the groove block is engaged with the fixing teeth.

[0011] Preferably, the limiting mechanism further includes a spring sleeved on the outer surface of the lifting rod, and two ends of the spring are respectively fixed to the rectangular block and the arc-shaped block.

[0012] Preferably, the limiting mechanism further includes a second rotating rod rotatably connected to the mounting shell through a bearing. Two fixing rods are symmetrically fixed on the outer surface of the second rotating rod. A clamping groove is formed at the center of the arc-shaped block, and the fixing rod is engaged with the corresponding clamping groove.

[0013] Preferably, the supporting mechanism includes a supporting strip fixed at the bottom end of the lower lifting rod. An installation block is fixed on one side of the top cover away from the lifting rod. A limiting strip is fixed at the top of the supporting strip, and the limiting strip is slidably connected to the installation block.

[0014] Compared with the prior art, the utility model provides a detonator initiation device, which has the following beneficial effects:

[0015] In this detonator initiation device, through the arrangement of the first rotating rod, the circular gear, the knob and the rack, the top cover can be used to protect the electronic devices in the detonator housing in a lifting manner. And in strong sunlight, the top cover can be lifted to block the sunlight, avoiding damage to the electronic devices in the detonator housing due to long-term exposure to sunlight, and also preventing sunlight from affecting the operator's line of sight. Through the arrangement of the limiting mechanism, the top cover is prevented from automatically falling under the action of external force, improving stability. Through the arrangement of the supporting mechanism, when preventing the top cover from falling, the supporting strip can be synchronously moved downward to support the detonator housing, preventing the detonator housing from contacting with gravel and reducing the wear on the detonator housing.

[0026] Reference Figures 1 - 5 On one side of the detonator housing 1 away from the mounting shell 3, a fixing block 71 is fixed, and a lifting strip 72 is fixed to the bottom of the top cover 2. The lifting strip 72 is slidably connected to the fixing block 71.

[0027] Reference Figures 1 - 5 As shown in Figures 1 - 5 , the limiting mechanism 8 includes two rectangular blocks 81 symmetrically fixed on the outer surface of the mounting shell 3. Lifting rods 82 are slidably arranged in the middle of the rectangular blocks 81. One end of each lifting rod 82 is fixed with an arc-shaped block 83. A limiting rod 84 is fixed to the top of the arc-shaped block 83. The limiting rod 84 is slidably connected to the rectangular block 81. The top end of the lifting rod 82 is fixed with a groove block 85. Fixed teeth 86 are fixed on the outer surface of the knob 6. The groove block 85 is engaged with the fixed teeth 86.

[0028] Reference Figures 1 - 5 As shown in Figures 1 - 5 , the limiting mechanism 8 further includes a spring 87 sleeved on the outer surface of the lifting rod 82. Two ends of the spring 87 are respectively fixed to the rectangular block 81 and the arc-shaped block 83.

[0029] Reference Figures 1 - 5 As shown in Figures 1 - 5 , the limiting mechanism 8 further includes a second rotating rod 88 rotatably connected to the mounting shell 3 through a bearing. Two fixing rods 89 are symmetrically fixed on the outer surface of the second rotating rod 88. A clamping groove is formed at the center of the arc-shaped block 83. The fixing rod 89 is engaged with the corresponding clamping groove.

[0030] In the present utility model, during use, by rotating the knob 6, the first rotating rod 4 and the circular gear 5 are driven to rotate. Since the circular gear 5 is engaged with the rack 7, the rack 7 and the top cover 2 can be driven to rise. By sliding the lifting strip 72 in the fixing block 71, the stability of the top cover 2 during rising is improved, so that the top cover 2 rises to a certain distance.

The staff operates the button in the detonator housing 1 to carry out blasting.

[0031] When the position of the top cover 2 is adjusted, the second rotating rod 88 can be rotated. The second rotating rod 88 drives the fixing rod 89 to rotate. When the fixing rod 89 abuts against the arc-shaped block 83, the upper arc-shaped block 83, the lifting rod 82 and the limiting rod 84 are driven to rise, squeezing the spring 87. The lifting rod 82 drives the groove block 85 to rise until the fixing rod 89 moves into the clamping groove formed on the outer surface of the arc-shaped block 83, so that the groove block 85 is engaged with the corresponding fixed teeth 86, limiting the knob 6 and preventing the top cover 2 from moving autonomously under the action of external force, improving the stability of the top cover 2.
