Description
Technical field
The utility model relates to a kind of overlap joint locking mechanism, belongs to oil field equipment auxiliary member technical field.
Background technique
In the oil field equipment that ocean and land use, often relate to the quick mounting locking of the similar products such as rig ladder, ramp, Cargo Lift, platform.In mounting mechanism in the past, there is pure hanger type but its not locking effect or otic placode pinned connection mechanism, there is certain potential safety hazard in pure hook not locking, and otic placode pinned connection mechanism exists the situation of installing difficulty, be also not easy to when some table space are limited realize otic placode pinned connection mode.
Model utility content
The utility model, for above-mentioned the deficiencies in the prior art, provides a kind of structure simple, easy to use and the overlap joint locking mechanism of safety and stability.
The technological scheme that the utility model solves the problems of the technologies described above is as follows: a kind of overlap joint locking mechanism, it is characterized in that, comprise two hook groups, locking plate, flexible fastening pin and running shaft, described pair of hook groups comprises symmetrical two circular arc clamping plate, the side of described circular arc clamping plate is connected as a single entity, opposite side and top and the bottom form open clip slot, and described circular arc clamping plate are provided with the first pin shaft hole and the second pin shaft hole, are also provided with the first spring hanging column, described locking plate is the semi-circle structure adapted with described clip slot, described locking plate is provided with first spacing hole corresponding with described first pin shaft hole and the second pin shaft hole and the second spacing hole, the top of described locking plate is provided with the second spring hanging column, described locking plate is inserted in described clip slot, and by running shaft, described first pin shaft hole and the first spacing hole are hinged, extension spring is provided with between described first spring hanging column and the second spring hanging column, described flexible fastening pin is located at the side of described circular arc clamping plate, and reach in described clip slot by described second pin shaft hole, be pressed on locking plate side.
The beneficial effects of the utility model are: be convenient to install and locking is reliable, be adapted at a few thing table top installing space not enough, use when otic placode cannot be used to connect, automatic locking can be realized, reduce the potential safety hazard produced because forgeing locking, simultaneously when removing locking, utilizing tension spring tension effect to open locking plate, realizing automatically controlling.
On the basis of technique scheme, the utility model can also do following improvement.
Further, described flexible fastening pin comprises housing and is located at the resilient key in described housing, and described housing is also provided with sliding-groove and locking slot, and described resilient key is provided with handle.
The beneficial effect of above-mentioned further scheme is adopted to be, simply easy to operate, play locking effect.

Embodiment
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figures 1 to 4, a kind of overlap joint locking mechanism, comprise two hook groups 1, locking plate 2, flexible fastening pin 3 and running shaft 4, described pair of hook groups comprises symmetrical two circular arc clamping plate 5, the side of described circular arc clamping plate is connected as a single entity, opposite side and top and the bottom form open clip slot 6, and described circular arc clamping plate are provided with the first pin shaft hole 7 and the second pin shaft hole 8, are also provided with the first spring hanging column 9, described locking plate 2 is the semi-circle structure adapted with described clip slot, described locking plate is provided with first spacing hole 11 and second spacing hole 12 corresponding with described first pin shaft hole and the second pin shaft hole, the top of described locking plate is provided with the second spring hanging column 10, described locking plate is inserted in described clip slot, and by described running shaft 4, described first pin shaft hole and the first spacing hole are hinged, extension spring 13 is provided with between described first spring hanging column 9 and the second spring hanging column 10, described flexible fastening pin 3 is located at the side of described circular arc clamping plate, and reached in described clip slot by described second pin shaft hole.
Described flexible fastening pin 3 comprises housing and is located at the resilient key in described housing, and described housing is also provided with sliding-groove and locking slot, and described resilient key is provided with handle.
When locking plate 2 is in non-locking state, described resilient key is reached in described clip slot 6 by described second pin shaft hole 8, and leans in the side of described locking plate; When locking plate 2 is in locking state, described resilient key inserts in described second pin shaft hole 8 and the second spacing hole 12.
As illustrated in Figures 5 and 6, of the present utility model pair of hook groups is fixed on platform, when on ladder 15 drag cylindrical part such as thick stick 14 grade to snap into circular arc clamping plate 5 time, the pressure that its deadweight produces is pressed onto the position that locking plate 2 protrudes from two hook groups 1, locking plate 2 is rotated around running shaft 4, when the second spacing hole of locking plate overlaps with the second pin shaft hole of described pair of hook groups, namely the latch of flexible fastening pin 3 stretches out under the effect of itself spring pressure, realizes blocking effect that ladder drag thick stick together with being locked to by locking plate 2 with two hook groups 1.When needs remove ladder, first move described handle to locking slot by hand, make resilient key deviate from described second spacing hole, above move Tuo Gang, locking plate 2 loses the pressure dragging thick stick, around running shaft revolution under the effect of extension spring 13, realizes removing locking.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
