Description
Technical Field
[0001] This utility model relates to the field of detonator testing technology, specifically a protective device for detonator quality testing. Background Technology
[0002] Detonators are the main initiating material in blasting engineering. Their main function is to generate initiation energy to detonate various explosives, detonating cords, and detonation tubes. They are now widely used in industries such as mineral mining and road construction.
[0003] Currently, at blasting construction sites, before loading detonators and explosives, the quality of detonators must be tested in accordance with national safety regulations. However, during the actual testing process, there is a risk that the detonators to be tested may be detonated. Therefore, in order to prevent detonator explosions from causing harm to people and facilities in the surrounding area, the existing technology usually places the detonators in protective barrels for testing or transportation.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0036] Please see Figures 1-6 A protective device for detonator quality inspection includes a protective barrel 1. A cover plate assembly is hinged to the top of the protective barrel 1, and a honeycomb-shaped partition assembly 2 is installed inside the protective barrel 1. The honeycomb-shaped partition assembly 2 includes a base 21. Several first partitions 22 are arranged from front to back on the top of the base 21, and several second partitions 23 are arranged from left to right on the top of the base 21. The several first partitions 22 and several second partitions 23 are interlocked and assembled with each other. Adjacent first partitions 22 and adjacent second partitions 23 can be combined to form independent storage spaces. Handles 16 are fixed on both sides of the protective barrel 1, and the corners of the handles 16 are all set as rounded corners.
[0037] In use, the honeycomb-shaped partition component 2 forms multiple independent storage spaces, providing independent and separate placement conditions for multiple detonators. The partitioning effect of the honeycomb-shaped partition component 2 can also prevent detonators from detonating against each other. It can also be used to disperse and store detonators during handling and transportation, preventing detonators from detonating against each other due to impact during transportation. After multiple detonators are placed, the whole device will be in a vertical and closed state, ensuring that the detonators will not fall out of the barrel. In the event of an accidental explosion, fragments will not splash out of the barrel and cause damage to the surrounding area.
[0038] Please see Figures 1-11 The bottom of several first partitions 22 is fixed to the fixed part of the base 21. The base 21 is fitted inside the bottom of the protective barrel 1. The top of the first partition 22, which is aligned with the middle of the base 21, is provided with several adjusting screw holes 24 along its own top structure from front to back, thereby providing locking conditions for the subsequent displacement adjustment of the first partition 22 on the base 21.
[0039] Each of the second partition plates 23 has a combination groove and a countersunk hole inside, and the space of the combination groove and the countersunk hole is connected. The second partition plate 23 can be engaged with the top of the corresponding base 21 through the combination groove. The countersunk hole of the second partition plate 23 is fitted with a positioning screw 25 that can be threadedly connected to the corresponding adjusting screw hole 24, thereby ensuring the stability of the combination connection between the base 21 and the first partition plate 22 and thus the structural strength.
[0040] When in use, considering that different sizes of space are needed to store non-standard detonators, the bases 21 are designed to be detachable and replaceable. The specific operation is as follows:
[0041] Adjust the two adjacent first partitions 22 to a suitable distance on the corresponding bases 21, referring to the distance between the two adjacent positioning screws 25. After adjustment, snap the two first partitions 22 and the corresponding bases 21 together, making them coplanar. The combination groove provides space for snapping. Then, fit the positioning screws 25 into the countersunk holes on the top of the first partitions 22 and then thread them into the corresponding adjusting screw holes 24. This achieves the adjustment and installation between the bases 21 and the first partitions 22, forming an independent storage space that can accommodate detonators of different specifications. The remaining bases 21 and first partitions 22 are adjusted in the same way.
[0042] Please see Figures 1-6 The cover assembly consists of a flip support 3, a first cover plate 4, and a torsion spring 5. The bottom side of the flip support 3 is fixed to the surface of the top side of the protective barrel 1. One side of the first cover plate 4 is fitted onto the inner top of the flip support 3 via a pin. The two ends of the torsion spring 5 are respectively fixed to the end surfaces of the pin and the inner wall structure of the top of the flip support 3. In a non-compressed state, the torsion spring 5 can utilize the support of the flip support 3...
[0043] When the first cover plate 4 covers and seals the top port of the protective barrel 1, the bottom surface of the first cover plate 4 can be in contact with the top surface of the first partition plate 22 and the top surface of the second partition plate 23. The bottom of the first cover plate 4 has several first semi-open strip grooves 6 opened laterally along its own structure, thereby providing clearance space for the lead wire connection of multiple subsequent detonators. A limiting structure is provided between the other side of the first cover plate 4 and the other side of the top of the protective barrel 1. The limiting structure includes a ring buckle assembly 7. The ring buckle assembly 7 includes an auxiliary seat 71 and a curved hanging plate 73. One side of the auxiliary seat 71 is fixed to the surface of the other side of the top of the protective barrel 1, and the other side of the auxiliary seat 71 is hinged to a C-type buckle 72 by a bearing. One end of the curved hanging plate 73 is fixed to the surface of the other side of the first cover plate 4, and the other end of the curved hanging plate 73 can be fastened with the C-type buckle 72.
[0044] During use, considering the sealing effect of the entire device during the transportation of detonators, the protective barrel 1 is sealed by the first cover plate 4 and related structures. The specific operation is as follows:
[0045] After multiple detonators are placed, the first cover plate 4 is flipped over and, supported by the flipping support 3 and the corresponding pin, seals the top port of the protective barrel 1. The torsion spring 5 deforms elastically, thereby sealing and protecting the multiple detonators placed inside the honeycomb partition assembly 2. Then, the C-shaped buckle 72 is flipped over so that it engages with the curved hanging plate 73. Subsequently, the elastic reset effect of the torsion spring 5 is activated to lock and limit the connection between the first cover plate 4 and the protective barrel 1.
[0046] Please see Figures 12-15 The cover plate assembly consists of a second cover plate 8 and two hollow seats 9. The two hollow seats 9 are fixedly connected to the surfaces on both sides of the top of the protective barrel 1. Both sides of the bottom of the second cover plate 8 are fixed with screws 10. One end of the screw 10 can pass through the corresponding hollow seat 9 and be threadedly connected to a limit nut 11.
[0047] Preferably, the bottom of the second cover plate 8 has several second semi-open strip grooves 15 opened laterally along its own structure. Both hollow seats 9 are fitted with buffer components. The buffer components include springs 12, damping rings 13, and limiting cylinders 14. The limiting cylinders 14 are fixedly fitted inside the corresponding hollow seats 9 and can be engaged with the corresponding screws 10. Springs 12 and damping rings 13 are both fitted on the top outer side of the corresponding screws 10, and the two ends of springs 12 are fixedly connected to the bottom of damping rings 13 and the inner wall of the bottom of hollow seats 9, respectively.
[0048] During use, considering the possibility of detonator explosion due to accidents during subsequent transportation or testing, in order to minimize losses, the protective barrel 1 will be buffered and sealed using the second cover plate 8 and related structures. The specific operation is as follows:
[0049] After multiple detonators are placed, the second cover plate 8 is placed over the top port of the protective barrel 1. The screws 10 connected to both sides of the second cover plate 8 are respectively fitted with two hollow seats 9 and extend through them. During the fitting process of the screws 10 and the hollow seats 9, the screws 10 are also fitted with the corresponding springs 12, damping rings 13 and limiting cylinders 14. After completion, the two limiting nuts 11 are threadedly connected to the two screws 10 until the bottom of the second cover plate 8 tightly covers and seals the top port of the protective barrel 1. At the same time, the springs 12 and damping rings 13 are simultaneously compressed. When there are detonators to ensure safety, in addition to the mechanical compression resistance of the screws 10, the second cover plate 8 and the limiting nuts 11, the springs 12 and the damping rings 13 will also provide damping and buffering to reduce the damage caused by the explosion.
