Description

The anti-detachment structure of a kind of pluggable module

Technical field

The utility model relates to modules such as the power supply installed or communication, the improvement of making at the latching structure of pluggable module in interpolation frame specifically on cabinets such as electric power screen cabinet.

Background technology

At present, when shielding modules such as power supply, communication are installed cashier's office in a shop, need fix an interpolation frame that matches with module in certain location.After then module being inserted interpolation frame, itself and interpolation frame are fixed with screw.When dismantling module, all need earlier screw to be unclamped so at every turn.Knockout screw has caused temporal waste on the one hand, and on the other hand, the dismounting of screw need realize by instruments such as screwdrivers, generally is difficult to free-hand finishing.Because our module surface all is the plastic-blasting processing, often dismounting also is a kind of damage to the surface simultaneously.

Summary of the invention

The purpose of this utility model is, the above-mentioned deficiency that adopts screw to bring when module such as power supply, communication is installed at existing screen cashier's office in a shop provides a kind of can conveniently plug, again the fixed structure on rapid wear piece module surface not.

Realize above-mentioned purpose, the technical scheme that the utility model adopted is: the anti-detachment structure of a kind of pluggable module, comprise that opening is located at the interpolation frame and the pluggable module on the surface of electric power cabinet, described interpolation frame can be fixed on screen cabinet inside, it is characterized in that, described module is provided with the lock pin that front end can skid off described module side, and described interpolation frame is provided with the lockhole that matches with described lock pin front end.

The fixed structure that above-mentioned lock pin matches with lockhole can replace screw that module is fixed in the interpolation frame.During installation, only need module is inserted interpolation frame to predeterminated position, the lock pin that slides then makes its front end stretch out and insert in the lockhole from the module side and gets final product, and it is very convenient to operate.

The mode that the realization lock pin slides has a variety of, and the simplest a kind of mode is that a push button is set on lock pin, promotes push button to realize skidding off and returning of lock pin.Described push button need be arranged on the position that hand can directly touch, as module exterior surface.Adopt this mode simple in structure, production cost is low, but needs manual operation to realize locking and unblanking, and, desire to make lock pin to remain on and skid off or reset mode, need to increase the dynamic damping that do not have of lock pin, perhaps otherwise designed location structure, otherwise the fixing of module will be very insecure.

The utility model proposes further improvement project on the said structure basis: a goring push spring is installed in the rear end at described lock pin, and establishes a guiding surface at the front end of lock pin towards a side of module direction of insertion.The module that adopts such structure only needs directly module to be inserted interpolation frame and gets final product when mounted.In the process of assigning, described lock pin can be retracted into inside modules at the effect lower compression goring push spring of guiding surface and interpolation frame mutual extrusion, when its front end over against lockhole, under the effect of goring push spring, described lock pin front end skids off and locks lockhole.During dismounting, need promote push button backward, so that lock pin is deviate from lockhole.The operation that the hand push push button is locked has been omitted in above-mentioned improvement; Simultaneously, goring push spring also plays the effect of locating detent at lock-out state, has guaranteed the stability of module at the interpolation frame internal fixation.

Though above-mentioned improvement structure operates easily, establishes push button at outer surface, influence on the one hand attractive in appearancely, especially as socket, the interface module of the part of interior decoration, the aesthetic measure of himself is very big to the influence in room.On the other hand, the push button of protrusion also is easy to be run into by external object, may damage push button when external object is run into push button, also may open lock pin.Be directed to this problem, the utility model proposes again further improvement project: remove the push button on the described lock pin, and be provided with one in described lock pin one side and move back the pin inclined-plane, simultaneously a pull bar that can rotate is being set on the described module in the plane perpendicular to the lock pin glide direction, the outer end of described pull bar can abut on the surface of described module, a side surface of returning direction towards lock pin of its inner was pressed against described moving back on the pin inclined-plane when described pull bar outwards rotated, and force lock pin to be received to move back to inside modules, until lock pin to lower slider release lock hole.In this improvement, the pull bar of fitting with the module surface is not easy to be run into by external object.And the employing of this Tiebar structure, the operation amplitude when having strengthened dismounting even if run into by external object and rotation by a small margin takes place, also can effectively avoid opening lock pin.

In the utility model, described module can only be provided with a described fixed structure in a side, also can respectively be provided with one in relative both sides or four sides in described module.Obviously, a plurality of fixed structures are set and effectively improve module in the stability of drawing together the frame internal fixation.

The utility model utilizes the buckle-type structure to substitute screw fixed structure of the prior art, and maximum beneficial effect is: simplified the installation and removal process of pluggable module on interpolation frame.In addition, the improvement project that the utility model provides also has characteristics such as simple in structure, specious, not fragile, that locking is firm.
