Abstract
This utility model relates to a kind of waterproof detonator connectedness, including restraint device and switching device, restraint device axially has intercommunicating pore, described switching device is that circular cone bench-type structure made by elastomeric material, it is interference fit that described switching device inserts restraint device, described intercommunicating pore is the most identical with detonator diameter, and outer material is water-swellable sealing material；This utility model has the beneficial effects that: frustum of a cone elastomeric material restraint device inserts switching device and effectively prevents water entrance generation from not leading quick-fried phenomenon, installs simple and convenient.
Description
Technical field
This utility model relates to a kind of detonator connectedness, particularly relates to a kind of waterproof detonator connectedness.
Background technology
At present, the most frequently used detonator four-way remains a device that simply can be concurrently accessed four detonators,
Bursting work typically utilizes four-way to connect detonator, and two parts use threaded, use more convenient.General fine
When, blasting network is reliable.But, if by chance encountering rainy weather must carry out blasting network connection, generally adopt
Way be to tie up the adhesive tape of certain length at four ports connected, do so not only expends the time much more very the most also can
Occur that the connectedness such as four-way is intake the phenomenon of not propagation of explosion, bring the biggest economic loss to bursting work.
Utility model content
This utility model solves the technical problem that and is: detonator connectedness overcast and rainy water inlet not propagation of explosion, installs troublesome asking
Topic.
The technical scheme that this utility model is provided by the above-mentioned technical problem of solution is:
A kind of waterproof detonator connectedness, including restraint device and switching device, restraint device axially has intercommunicating pore, institute
Stating restraint device is that circular cone bench-type structure made by elastomeric material, and it is interference fit that described restraint device inserts switching device, circular cone
Bench-type restraint device inserts switching device and effectively prevents water from entering switching device.
Described intercommunicating pore is the most identical with detonator diameter, prevents through switching device extruding when detonator inserts intercommunicating pore
Water enters switching device by intercommunicating pore.
Described restraint device circular cone bench-type outer material is water-swellable sealing material, and when meeting water, outer material starts
Expansion prevents water from entering.
Intercommunicating pore on described restraint device is 4, for four-way connector.
The elastomeric material of described restraint device is the similar materials such as rubber.
There is limited step inside described switching device prevents restraint device from deviating from, and its cavity is plum blossom-shaped, operative constraint
Detonator.
This utility model has the beneficial effects that: frustum of a cone elastomeric material restraint device inserts switching device and effectively prevents water from entering
Enter to produce and do not lead quick-fried phenomenon, install simple and convenient.
Accompanying drawing explanation
Fig. 1 is waterproof detonator connectedness schematic diagram；
Wherein, 1, intercommunicating pore, 2, restraint device, 3, switching device.
Detailed description of the invention
Referring to the drawings, during in this utility model, detonator inserts 4 intercommunicating pores 1 on restraint device 2 after, be inserted into
In switching device 3, restraint device 2 and switching device 3 are interference fit, form extruding, and are formed crowded to detonator and intercommunicating pore 1
Pressure, and restraint device 2 outer water-swellable sealing material, effectively prevent water from entering, relatively in the past tightening way, restraint device
2 are inserted directly into switching device 3 convenience.
