Abstract
The utility model discloses a communication box body and in particular relates to a threshold device applied to the communication box body. The threshold device comprises a mounting plate (1), a movable bolt (2) and a pull rod (3), wherein a fixed screw hole for fixing the mounting plate with a door panel of a communication box is formed in the mounting plate, one end of the pull rod (3) is provided with a fixing plate (5) for fixing the pull rod with the top of the inner side of the communication box, a strip-type hole (4) is also formed in the mounting plate (1), the movable bolt (2) is fixed on one end of the pull rod (3) and is embedded and buttoned in the strip-type hole (4), the strip-type hole (4) is provided with a round hole in the position of the movable bolt (2) when the communication box is opened, and the diameter of the round hole is more than the width of the strip-type hole (4). The threshold device has the function of limiting opening and closing tracks and positions of the door panel of the communication box and is simple in structure, easy to maintain and especially applicable to the communication box in the field.
Description
Technical field
The utility model relates to a kind of communication casing, relates in particular to the threshold device of using on a kind of casing of communicating by letter.
Background technology
In the fiber cable cross connection box, Cabinet etc. needs generally all to be provided with threshold device in the fixing communication casing of door, because that this class casing is mounted in is outdoor, then requires its internal construction to oversimplify, to maintain easily.But often or how existing various threshold device substantially all is the unlatching skew fixed gate Board position and designing with improved that prevents door-plate; its result also becomes increasingly complex; cause this threshold device in the maintenance in later stage, to seem and very trouble and inconvenience are unfavorable for field work.
The utility model content
The purpose of this utility model is the threshold device of using on a kind of casing of communicating by letter is provided, and has solved the problem that the threshold device that is used for the communication casing is at present safeguarded inconvenience.
For addressing the above problem, technical solution adopted in the utility model is:
The threshold device of using on a kind of casing of communicating by letter, comprise installing plate, movable bolt and pull bar, wherein said installing plate is provided with the fixing threaded hole that interfixes for the door-plate with the case of communicating by letter, one end of described pull bar is provided with for the fixed head that interfixes with the case inside top of communicating by letter, also be provided with bar hole on the installing plate, described movable bolt be fixed on the end of pull bar and clasping in bar hole, described bar hole is provided with circular hole at place, movable bolt position when the communication case is opened, and the diameter of circular hole is greater than the width of described bar hole.
Further technical scheme is that the one side that above-mentioned installing plate is provided with fixing threaded hole becomes the L type each other with the one side that is provided with bar hole.
The beneficial effect that adopts technique scheme to produce is: the utility model can not only well play folding track and the position of limiting telecommunication chamber door plate, and itself is simple in structure, and is easy to maintenance, is fit to very much be installed in open-air communication case and uses.
Description of drawings
Fig. 1 is the structure indicator diagram of the embodiment of threshold device that uses on a kind of casing of communicating by letter of the utility model;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Fig. 1 and Fig. 2 show an embodiment of the threshold device of using on a kind of casing of communicating by letter of the utility model: the threshold device of using on a kind of casing of communicating by letter, comprise installing plate 1, movable bolt 2 and pull bar 3, wherein said installing plate 1 is provided with the fixing threaded hole that interfixes for the door-plate with the case of communicating by letter, one end of described pull bar 3 is provided with for the fixed head 5 that interfixes with the case inside top of communicating by letter, also be provided with bar hole 4 on the installing plate 1, described movable bolt 2 be fixed on the end of pull bar 3 and clasping in bar hole 4, described bar hole 4 is provided with circular hole at place, movable bolt 2 positions when the communication case is opened, and the diameter of circular hole is greater than the width of described bar hole 4.
According to a preferred embodiment of the threshold device of using on a kind of casing of communicating by letter of the utility model, the one side that installing plate 1 is provided with fixing threaded hole becomes the L type each other with the one side that is provided with bar hole 4.The installing plate 1 of L type can be fixed on the door-plate of communication case easily, and can the slip between movable bolt 2 and the bar hole 4 not impacted.
The utility model can be installed in installing plate 1 on the door-plate of communication case by fixing threaded hole, pull bar 3 is fixed on the communication case inside top by fixed head 5, and in the moving process of door-plate, movable bolt 2 slidably reciprocates in bar hole 4.The utility model can not only well play folding track and the position of limiting telecommunication chamber door plate, and itself is simple in structure, and is easy to maintenance, is fit to very much be installed in open-air communication case and uses.
