Abstract

The utility model relates to a drawing-type assembly unlock mechanism. A flexible pull ring is connected with a sheet-metal part. The two sides of the front parts of a casing are each provided with a spring groove. A spring is installed in each spring groove respectively. The middle parts of the casing are provided with position limiting grooves. The sheet-metal part has a U-shaped structure. A bending shrapnel is arranged at each inner side of the middle parts of the sheet-metal part. The tail parts of the sheet-metal part are provided with ear-shaped projections. The tail ends of the sheet-metal part are provided with bayonet projections. The bending shrapnels extend into the spring grooves and buckle the bottom parts of the springs so that power for reset of the sheet-metal part is provided. The ear-shaped projections are arranged in the position limiting grooves. The flexible pull ring drives the sheet-metal part which is connected with the flexible pull ring to move forwards and the bayonet projections at the tail ends of the sheet-metal part also move forwards so that a lock mechanism which fixes the casing on the rack is forced to open. The assembly can be taken out freely when the assembly and the rack are at an unlock state and after the assembly is taken out, the sheet-metal part is reset under an action of reverse thrusts of the springs. When the assembly is inserted into the rack again, the lock mechanism of the rack locks the casing. The drawing-type assembly unlock mechanism is used for facilitating taking off the assembly, which is inserted into the rack, from the rack in an auxiliary way and is simple and convenient to operate.

Description

Drawing type assembly release mechanism

Technical field

The utility model relates to the optical module release mechanism, relates in particular to a kind of drawing type assembly release mechanism, takes off from frame for the assembly of the auxiliary frame of planting is convenient.

Background technology

In the optical transport technology field, the optical module miniaturization can increase network connection port density, needs for this, has in the world multiple standards to define modular shape to reduce size.And for the quantity of extension module in unit area, just the module in frame need to be to the storehouse shape arranges, in order in limited space, obtain maximum module numbers, the operating space of corresponding each module need to reduce as much as possible, this just need to have more perfectly module to discharge and latch-up structure, so each module all is provided with the plug operation that a release mechanism will be very beneficial for module.

The shortcomings such as existing assembly release mechanism exists that structure is comparatively complicated, member morely should not be assembled, release is difficult for.

Summary of the invention

The purpose of this utility model is to overcome the deficiency that prior art exists, and provides that a kind of structure body is simplified, drawing type assembly release mechanism simple to operate, is intended to reduce costs and is easy to and realize.

The purpose of this utility model is achieved through the following technical solutions:

Drawing type assembly release mechanism, characteristics are: comprise housing, sheet metal component, spring and flexible draw ring, described flexible draw ring is connected with sheet metal component, the both sides of described housing front portion respectively are provided with a spring groove, one spring is installed respectively in spring groove, the middle part of housing is provided with limited impression, described sheet metal component is U-shaped structure, the inboard at sheet metal component middle part is provided with bent spring plate, the sheet metal component afterbody is provided with ear shape projection, the sheet metal component tail end is provided with bayonet raised, and bent spring plate stretches to spring groove and fastens the power that the spring bottom provides sheet metal component to reset; Ear shape projection is placed in limited impression;

Flexible draw ring drives the sheet metal component reach be attached thereto, the bayonet raised of sheet metal component tail end also moves forward the lockable mechanism of stationary housing on frame is strutted, assembly and frame are in released state, assembly can freely take out, reaction thrust effect by spring after taking-up resets sheet metal component, when assembly reinserted frame, the lockable mechanism of frame pinned housing.

Further, above-mentioned drawing type assembly release mechanism, wherein, described flexible draw ring connects as one by injection moulding mode and sheet metal component.

The substantive distinguishing features of technical solutions of the utility model and progressive being mainly reflected in:

The utility model release mechanism structure body is succinct, simple to operate, and, by a flexible draw ring, has increased the put forth effort area of staff to assembly in the situation that do not increase the frame volume, and assembly is more easily plugged, and appearance looks elegant, and can reduce costs.Assembly for the auxiliary frame of planting is convenient to take off from frame, is easy to realize, is applicable to the optical module release.

The accompanying drawing explanation

Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:

Fig. 1: the schematic diagram of the utility model release mechanism;

Fig. 2: the decomposing schematic representation of the utility model release mechanism.

Embodiment

As Fig. 1, shown in Figure 2, drawing type assembly release mechanism, comprise housing 1, sheet metal component 2, spring 4 and flexible draw ring 3, flexible draw ring 3 connects as one by injection moulding mode and sheet metal component 2, the both sides of housing 1 front portion respectively are provided with a spring groove 5, one spring 4 is installed respectively in spring groove 5, the middle part of housing 1 is provided with limited impression 6, restriction sheet metal component sliding scale, sheet metal component 2 is U-shaped structure, the inboard at sheet metal component 2 middle parts is provided with bent spring plate 7, bent spring plate 7 is be used to fastening the spring 4 in assembly spring groove 5, the sheet metal component afterbody is provided with ear shape projection 8, the effect of ear shape projection 8 is to limit sheet metal component is advanced when moving forward and backward distance, the sheet metal component tail end is provided with bayonet raised 9, after sheet metal component 2 is assembled with housing 1, bent spring plate 7 stretches to spring groove 5 and fastens the power that spring 4 bottoms provide sheet metal component to reset,

When this assembly is used for release, pull flexible draw ring 3, flexible draw ring 3 drives sheet metal component 2 reaches that are attached thereto, the bayonet raised 9 of sheet metal component tail end also moves forward the lockable mechanism of stationary housing on frame is strutted, assembly (housing and lockable mechanism or perhaps module) is in released state with frame, and assembly can freely take out, and the reaction thrust effect due to spring after taking-up resets sheet metal component, when assembly reinserted frame, the lockable mechanism of frame pinned housing.

In sum, the utility model release mechanism structure body is succinct, simple to operate, and, by a flexible draw ring, has increased the put forth effort area of staff to assembly in the situation that do not increase the frame volume, and assembly is more easily plugged, and appearance looks elegant, and can reduce costs.Assembly for the auxiliary frame of planting is convenient to take off from frame, is applicable to the optical module release.

What need to understand is: the above is only preferred implementation of the present utility model; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
