Abstract
The utility model discloses an automatic stop device of optical cable distributing box door plant, including spacing support, spacing connecting piece, set screw, stop screw, be provided with the spout on the spacing support to install at the door plant inboardly, the set screw for the one end of spacing connecting piece installs in the box, it is fixed with the other end of spacing connecting piece that stop screw passes the spout of spacing support. The beneficial effects of the utility model reside in that, control door plant opening angle, it influences the hinge to avoid door plant opening angle to exceed the stroke scope, leads to the fact the door plant to come off, self -service limit locking is opened to the door plant, and operation maintenance is convenient, and the door plant cuts out manual control, avoids appearing the accident.
Description
Technical field
The utility model relates to optical cable joining box door plate automatic limit device in a kind of FTTH construction, can meet automatic spacing function when optical cable joining box door plate is opened, belong to communication network device technical field.
Background technology
During current FTTH builds, front is all adopted to open the door for optical cable for communication cross-connecting box, the unlatching of door-plate and the closed mode adopting hinge Unscrew, after door-plate opening angle is greater than hinge stroke range, hinge easily fractures by external force is excessive, and because fiber cable cross connection box is exterior product, easily swings because of wind-force reason under door-plate opening in operating process, constructing operation is very inconvenient, and easily causes hinge to fracture.
Summary of the invention
For the deficiency of traditional product, the utility model provides a kind of optical cable joining box door plate automatic limit device, because sliding in pilot hole by gravity tenesmus, realizes the function of automatic spacing when door-plate is opened to stop means after certain angle, at closing time, with Hand supplementary locating part upwards held up and close the door.
The technical matters solved: 1, door-plate rotates the hinge adopted has certain limit for angle, easily causes hinge to fracture as excessive, needs a protective device controlling open angle; 2, the installation of stop means needs the convenience considering operation.
In order to realize foregoing invention object, the utility model adopts following technical scheme:
A kind of optical cable joining box door plate automatic limit device, comprise limiting bracket, limit connector, gib screw, stop screw, described limiting bracket is provided with chute, and be arranged on inside door-plate, one end gib screw of described limit connector is arranged in casing, and described stop screw is fixed through the chute of limiting bracket and the other end of limit connector.
Preferably, described stop screw is three-decker, comprises the first thread layer, fixing for stop screw and limit connector; Sliding layer, slides in limiting bracket chute for limit connector; Fixed bed, is opened to the locking of position after certain position for door-plate.
Preferably, described gib screw is double-decker, comprises the second thread layer, fixing for gib screw and limit connector; Rotating layer, rotates for realizing limit connector.
The beneficial effect of the utility model example is: 1: control door-plate opening angle, avoid affecting hinge because door-plate opening angle is exceeded stroke range by artificial origin or unnecessary external force, cause door-plate to come off; 2: self-service limitation locking opened by door-plate, convenient operating maintenance, door-plate cuts out Non-follow control, avoids occurring engineering accidents such as crushing at closing time.
Accompanying drawing explanation
Fig. 1 is the utility model schematic appearance.
Fig. 2 is gib screw side schematic view of the present utility model.
Fig. 3 is stop screw side schematic view of the present utility model.
Wherein: 1-1 is limiting bracket; 1-2 is limit connector; 1-3 is gib screw; 1-4 is stop screw; 2-1 is the second thread layer; 2-2 is rotating layer; 3-1 is the first thread layer, and 3-2 is sliding layer, and 3-3 is fixed bed.
Embodiment
Below in conjunction with accompanying drawing and concrete embodiment, the utility model is described in more detail.
The technical scheme that the utility model adopts is: limit connector one end is fixed on the casing of needs installation by gib screw, limiting bracket is arranged on door-plate side, limiting bracket and limit connector other end stop screw are fixed, stop screw adopts three-decker, gib screw is double-layer structure, realizes automatic spacing function when door-plate is opened.
The utility model schematic appearance as shown in Figure 1, limiting bracket (1-1) screw is arranged on the backboard inside door-plate, limit connector (1-2) one end gib screw (1-3) is arranged in box inside fixed orifice, and stop screw (1-4) is fixed through the chute of limiting bracket (1-1) and the screw hole of limit connector (1-2).
When door-plate is in closed condition, limit connector (1-2) and limiting bracket (1-1) are in parastate, when door-plate is opened, limit connector (1-2) with the fixing one end of limit connector (1-2) and casing for axle center, to inner rotary within the scope of the chute of limiting bracket (1-1), when door-plate is opened to limiting bracket (1-1) end, stop screw (1-4) for fixing limit connector (1-2) falls downwards because of gravity, sliding layer (3-2) is just fallen in fixed hole position, realizes the limit function of door-plate.
Although the utility model with preferred embodiment openly as above; but drawings and Examples are not for limiting the utility model; anyly be familiar with this those skilled in the art; not departing from the spirit and scope of the utility model; from when making various changes or retouch, all same within protection domain of the present utility model.What therefore protection domain of the present utility model should define with the claims of the application is as the criterion.
Claims (3)
