Abstract
A mining explosion-proof pinned coupler consists of a positive pin and a negative pin. The positive pin comprises a positive plug and a positive socket, the negative pin comprises a negative pin and a negative socket, the inner diameter of the positive plug matches with a pin of phi 9mm, and the inner diameter of the negative plug matches with a pin of phi 7mm. Simultaneously, the outer diameter of the positive socket matches with a quick-release-preventive wide guide groove, and the outer diameter of the negative socket matches with another quick-release-preventive wide guide groove. The mining explosion-proof pinned coupler adopts the lasted foolproof structure, is novel in concept and simple in process, and eliminates equipment fault and potential safety hazards caused by positive and negative plugging errors fundamentally.
Description
Technical field
The utility model relates to a kind of pinned coupler, refers in particular to a kind of mining flame-proof latch connector.
Background technology
For a long time, the structure of the mining flame-proof latch connector that the flameproof special type battery locomotive uses mostly is the monotubular acyclic type, and every cover is divided into two of " just ", " bearing ".For preventing that " just ", " bearing " from mispluging, cause the electric locomotive electric fault, employing be that the plug pin is respectively φ 9, φ 7, the anti-pull-off suddenly of socket 0 well width that leads is respectively the anti-mis-insertion design of 10mm, 8mm.This kind structural design is incomplete, can not play foolproof function safely, can not insert negative pole though greatest problem is a positive pole, and negative pole can insert positive pole very easily, and very big potential safety hazard is arranged.
Summary of the invention
The purpose of this utility model is to fundamentally addressing the above problem, and the interior warp and the external diameter of the flameproof joint of latch carried out improving design; A kind of mining flame-proof latch connector is provided, its up-to-date error-proof structure design, novel, technology is simple, fundamentally stop positive and negative mispluging and caused equipment fault and potential safety hazard.
For achieving the above object, the solution that the utility model is taked is: a kind of mining flame-proof latch connector, and it is made of positive latch and negative latch, and positive latch comprises anode plug and positive pole socket, negative latch comprises cathode plug and anode socket, and the internal diameter of anode plug is
Join φ 9mm pin, the internal diameter of cathode plug is
Mm joins φ 7mm pin, simultaneously, and positive pole socket
What external diameter was joined is
Wide anti-pull-off gathering sill suddenly, anode socket
What the mm external diameter was joined is
Wide anti-pull-off gathering sill suddenly.
Like this, large diameter
Anode plug if misplug in little external diameter
Anode socket because the pin of plug φ 9mm is stoped by the wide anti-pull-off gathering sill suddenly of 8mm and can not enter; Otherwise, little internal diameter
The cathode plug of mm is if misplug in big external diameter
Positive pole socket can not enter the big positive pole socket of external diameter because the internal diameter of plug is little.This up-to-date error-proof structure design, novel, technology is simple, fundamentally stop positive and negative mispluging and caused equipment fault and potential safety hazard.

Embodiment
Below in conjunction with embodiment and accompanying drawing thereof the utility model is described again.
Referring to Fig. 1-Fig. 6, a kind of mining flame-proof latch connector, it is made of positive latch 1 and negative latch 2, and positive latch 1 comprises anode plug 3 and positive pole socket 4, and negative latch 2 comprises cathode plug 5 and anode socket 6, and the internal diameter of anode plug 3 is
Join φ 9mm pin, the internal diameter of cathode plug 5 is
Join φ 7mm pin, simultaneously, positive pole socket 4
What external diameter was joined is
Wide anti-pull-off gathering sill 7 suddenly, anode socket 6
What external diameter was joined is
Wide anti-pull-off gathering sill 8 suddenly.
This up-to-date error-proof structure design is applicable to all monotubular acyclic type pinned couplers.
