Description

A kind of rack advances the wire hole locking device

Technical field

The utility model relates to the equipment of electronic applications, relates in particular to a kind of rack and advances the wire hole locking device.

Background technology

In communication network device; various cable turnover racks are arranged; because the difference in the cabling amount of various products and line footpath; usually stayed certain remaining space at its import and export; haunt and often have mouse in the environment for use of communication equipment, under certain conditions, mouse will enter the rack damage equipment by cabling mouth remaining space; therefore, the sealing to equipment just becomes very necessary.

The version that the rack of existing communication equipment advances the wire hole locking device has following several usually:

A, pyramid-like structure

Pyramid-like structure is according to the size of cable hole, be divided into two kinds in two pagodas and single pagoda, be illustrated in figure 1 as two pagoda structures, be illustrated in figure 2 as single pagoda structure, pagoda 2 is installed on the framework 1, the material of pagoda 2 is generally selected natural rubber for use, flexible, mouse is difficult for breaking by the teeth, and design has the annulus of the different sizes that can cut on the pagoda 2, and big ring is greatly then cut in the many or line footpath of line amount, few or the line of line amount footpath is little then cuts little ring, because rubber is flexible, can seal largely around the turnover cable, its mounting means is for installing by card base 11 and chucking around the rack wire inlet-outlet.

B, stainless steel press strip structure

Be illustrated in figure 3 as stainless steel press strip structure, Figure 4 shows that stainless steel press strip scheme of installation, stainless steel press strip 3 is stuck on the cable-through hole 4 of framework 1 item by item, when needs during line, take off the cable-through hole 4 that one or a few stainless steel press strip 3 wherein exposes the needs size and get final product.

C, drawing and pulling type structure

As shown in Figure 5 and Figure 6, the drawing and pulling type structure mainly realizes adjusting and sealing to cable-through hole 4 by pull plate 5, and design has two chutes 51 on the pull plate 5, guarantees that pull plate 5 is along pull direction 6 pull that moves.

Be illustrated in figure 6 as the pull plate scheme of installation, be screwed with two screws 52 on one side of cable-through hole 4, screw 52 is screwed on the framework 1 through the chute 51 on the pull plate 5, and when not needing cable, pull plate 5 is sealed whole cable-through hole 4; When needing cable, unclamp screw 52, draw back pull plate 5, pull on pull plate 5 again after cable passes and seal around the cable.

Above-mentioned three kinds of structures, because the defective in the design, so when operation, be difficult to all the cable that passes is wherein realized sealing well that concrete shortcoming is described below:

Pyramid-like structure is because outstanding plane is higher, so environment for use is limited to, and annulus all around tears difficulty, and it is regular to be difficult to control openings of sizes and shape;

Stainless steel press strip structure then scratches cable easily, and in addition, metal rigidity greatly also causes the size adjustment in hole to be difficult for, and then causes usually can staying very big neutral under cabling amount situation seldom, can't effectively seal;

Drawing and pulling type mechanism can only be to a direction pull owing to the restriction that is subjected to the rack window frame structure, the position of greatly having limited cabling, and when cable is few, also can't realize effective sealing.

Summary of the invention

The utility model provides a kind of rack to advance the wire hole locking device, to solve the problem that line position is restricted, sealing effect is relatively poor of walking that exists in the prior art.

For addressing the above problem, the technical scheme that the utility model adopted is:

A kind of rack advances the wire hole locking device, comprises framework, it is characterized in that: described framework connects a soft open-bag along periphery, and open-bag is provided with the closing in rope that can tighten described peristome at least away from the peristome of framework one end.

The beneficial effects of the utility model are: by connecting a soft open-bag in framework along periphery, peristome away from framework in the open-bag connects at least one closing in rope that can tighten described peristome, like this, after cable passed by peristome, rope is tightened peristome with closing up, adopt this structure to rule, opening etc., just can effectively seal the neutral around the cable, reach good protection against rodents effect, and the utility model can satisfy the installation needs of the cable in various cross sections, therefore, the utility model can reach good sealing process, have extraordinary operability and maintainability, with low cost, be fit to carry out large-scale production; The shut that the utility model adopted can be used for not cabling or does not need on the standby hole of cabling, advances wire hole and blocks corresponding, makes rack more attractive in appearance, also can have the effect of protection against rodents simultaneously; A plurality of screws are set on framework and the closure panel edge, and the binding that can be used for the utility model and rack is installed, and improves practicality of the present utility model.

Embodiment

With embodiment the utility model is described in further detail with reference to the accompanying drawings below:

According to Fig. 7 and Fig. 8, the utility model comprises that one is tetragonal framework 1, and a plurality of screws 10 are set on the framework 1; Framework 1 connects a soft open-bag 7 along periphery, and this open-bag 7 can be taper or straight barrel-shaped cloth bag.When open-bag 7 was taper, it was away from the opening minimum of the peristome of framework 1; When open-bag 7 is straight when barrel-shaped, its opening away from the peristome of framework 1 is the same with the framework end big.In addition, this open-bag 7 is provided with the closing in rope 71 that can tighten described peristome away from the peristome of framework 1 one ends, and is enough for guaranteeing the firmness of tightening certainly, and several ropes 71 that close up also can be set more.

As shown in Figure 7, the utility model comprises that also one can cover the netted shut 9 of framework 1, and shut 9 edges are provided with a plurality of screws 90.

In use, as shown in Figure 8, sub-thread or multiply cable 8 by in the middle of the framework 1 and after the peristome of open-bag 7 passes, are restricted with closing in and 71 peristome to be tightened got final product.

Shut 9 can be used for not cabling or does not need on the standby hole of cabling, advances wire hole and blocks corresponding, and shut 9 can be installed on the rack by screw 90,10 with framework 1 during installation, and the open-bag 7 on the framework 1 places rack inside.
