Specific embodiment 1

[0038] See also Figures 1 to 5The utility model is a safe storage device for blasting detonators, comprising a box body 1 and universal wheels 101 installed at four corners of the bottom thereof, both sides of the front end face of the box body 1 are movably connected to the box door 102 through hinges, a placement plate 103 is evenly and fixedly connected to the inside of the box body 1 from top to bottom, the front end and rear end of the upper surface of the placement plate 103 are respectively provided with adjustment grooves 1031 and ball grooves 1032, the inside of the adjustment groove 1031 is evenly and horizontally arranged with front slide seats 105, the front end face of the front slide seat 105 is provided with a pressing groove 1051, a storage box 107 is installed at the bottom of the outer wall of one side of the box body 1, and a limiting component 2 is arranged inside the pressing groove 1051; the limiting component 2 comprises a pressing block 201 and a card plate 202 fixedly connected to its inner wall, and a connecting rod 203 is evenly and fixedly connected to the upper inner wall of the card plate 202 along the horizontal direction.

[0039] Specifically, slots 1033 are evenly spaced along the horizontal direction at the inner front end of the adjustment groove 1031, and rear slide seats 106 are evenly installed along the horizontal direction inside the ball groove 1032. The front and rear adjacent front slide seats 105 and rear slide seats 106 are fixedly connected by a common plate 104. A rolling ball 1061 is embedded in the bottom of the rear slide seat 106. The other end of the connecting rod 203 passes through the through hole on the outer wall of the fixed plate 205 and is connected to the limit plate 206. A compression spring 204 is sleeved on the outer side of the outer wall of the connecting rod 203. The compression spring 204 is located between the clamping plate 202 and the fixed plate 205. The outer wall of the fixed plate 205 is fixed to the inner wall of the pressing groove 1051.

[0040] Furthermore, the box 1 can be adjusted to a suitable position through the universal wheel 101 for easy transportation, the front slide 105 can slide inside the adjustment slot 1031, and the rear slide 106 can slide inside the ball slot 1032. The size of the slot 1033 is larger than the bottom size of the card plate 202, and can play an auxiliary sliding role under the action of the rolling ball 1061. The cross-section of the card plate 202 is L-shaped, and the pressure block 201 and the limit plate 206 are connected by the connecting rod 203, which plays a role of connecting transmission, and can drive the card plate 202 to move under the action of the elastic performance of the compression spring 204.

[0041] The operation process of this embodiment is as follows: first, the blasting detonator is clamped and limited by the clamping mechanism on the surface of the front slide 105 and the rear slide 106, and when the blasting detonators of different sizes are clamped and limited at intervals, the pressing block 201 is pushed inward, and the pressing block 201 is forced to drive the clamping plate 202 to move inside the pressing groove 1051, and the inner wall of the clamping plate 202 is connected to the limiting plate 206 through the connecting rod 203, so when the clamping plate 202 moves, the limiting plate 206 is pushed to move through the connecting rod 203, and the compression spring 204 is squeezed, so that the bottom end of the clamping plate 202 can be moved out of the slot 1033, and then the front slide 105 and the rear slide 106 are connected to the limiting plate 206 through the connecting rod 203. Under the action of the plate 104, the rear slide seat 106 and the rolling ball 1061, they slide and adjust their positions inside the adjustment groove 1031 and the ball groove 1032, and after the position adjustment between the adjacent front slide seat 105, the common plate 104 and the rear slide seat 106 is completed, the force on the pressure block 201 is stopped. At this time, the card plate 202 is ejected under the elastic performance of the compression spring 204, and is inserted into the adjacent slot 1033 to complete the spacing adjustment, thereby facilitating the staff to quickly adjust the spacing of the clamping limit according to the size of the blasting detonator, saving time and effort, and having high work efficiency. At the same time, it is convenient for the staff to store and access the blasting detonator, and it is convenient to use. Specific embodiment 2

[0043] See also Figure 2 , Figure 6 , Figure 7 and Figure 8 On the basis of the specific embodiment 1, what is different from the first embodiment is that: a winding assembly 3 and a locking assembly 4 are provided, the winding assembly 3 includes a lower rotating shaft 301 and a winding roller 302 sleeved at the center position of its outer wall, and a ratchet 303 is arranged at the front end of the outer wall of the lower rotating shaft 301; the locking assembly 4 includes a bracket 401 and a pull plate 402 with a gap arranged just above it, and a connecting rod 403 is fixedly connected to the bottom center position of the pull plate 402, which solves the problem that the existing safe storage device for blasting detonators lacks corresponding anti-static measures for the storage box when in use, thereby posing certain safety hazards during use.

[0044] Specifically, a conductive chain 3021 is wound around the outer side of the outer wall of the winding roller 302, an upper rotating shaft 304 is rotatably connected just above the rear end of the lower rotating shaft 301, a coil spring 305 is wound around the outer wall of the upper rotating shaft 304, the other end of the coil spring 305 is fixed to the rear end of the outer wall of the lower rotating shaft 301, a pull ring 4021 is fixedly connected to the top center position of the pull plate 402, the other end of the connecting rod 403 passes through the through hole on the upper surface of the bracket 401 and is connected to the block 405, a reset spring 404 is sleeved on the outer side of the outer wall of the connecting rod 403, and the reset spring 404 is located between the inner wall of the bracket 401 and the block 405.

[0045] Furthermore, the rotation of the lower shaft 301 will drive the ratchet 303 and the winding roller 302 on its outer wall and one end of the coil spring 305 to rotate. The conductive chain 3021 can be wound on the outer wall of the winding roller 302. Under the action of the connecting rod 403, the pull plate 402 and the block 405 can be connected to play a role in connecting transmission. Under the action of the elastic performance of the reset spring 404, the block 405 can be driven to move. Under the action of the coil spring 305, the lower shaft 301 can be driven to rotate, thereby achieving the purpose of rotating the winding roller 302.

[0046] The operation process of this embodiment is as follows: after the blasting detonator is stored, the box body 1 can be adjusted to a suitable position under the action of the universal wheel 101, and then the conductive chain 3021 is pulled outward, and the conductive chain 3021 is driven by the force to drive the winding roller 302 and the lower shaft 301 on the inner wall to rotate, so that the conductive chain 3021 can be pulled out to a certain length, and the rotation of the lower shaft 301 will drive the ratchet 303 and the coil spring 305 at its rear end to be wound on its outer wall, so that the conductive chain 3021 is in contact with the ground, which plays a role in releasing static electricity to protect the blasting detonator. When the conductive chain 3021 needs to be retracted, the pull ring 4021 is pulled upward, and the pull ring 4021 is driven by the force to pull the pull ring 4021. The plate 402 moves up, and the inner wall of the pull plate 402 is connected to the block 405 through the connecting rod 403. Therefore, when the pull plate 402 moves up, the block 405 will be driven to move under the action of the connecting rod 403 and squeeze the reset spring 404. At this time, the limiting effect of the block 405 on the ratchet 303 can be cancelled, and then the elastic performance of the coil spring 305 will be retracted to the outer wall of the upper rotating shaft 304 and wound around, thereby driving the lower rotating shaft 301 to rotate, so that the winding roller 302 rotates and winds the conductive chain 3021 around its outer wall, completing the recovery of the conductive chain 3021, and then facilitating the staff to quickly recover the conductive chain 3021, saving time and effort, and high work efficiency.
