Description
Technical field
The utility model belongs to high and low voltage electric distribution equipment technical field, more particularly, to a kind of high and low voltage electric distribution equipment box
Door-plate limiting device.
Background technique
With being constantly progressive for society, the quickening of process of industrialization obtains more and more extensive in high-low pressure complete set of equipments
While use, the requirement to production run safety is also higher and higher, and the door of currently widely used high-low pressure complete set of equipments
Plate is all without limiting device, and in open and close door operation or maintenance of equipment, cabinet door can swing back and forth, and is especially influenced family by weather
The outer low voltage complete set used is easy to crush people or damages the component on door and door, influences being normally carried out for work, exist
Great security risk.
Summary of the invention
The purpose of this utility model is that improve prior art deficiency and provide a kind of structure it is simple, it is easy to use, limit
Level really, the reliable door-plate limiting device of door-plate locking.
The purpose of this utility model is achieved in that a kind of door-plate limiting device, including movable doorboard and cabinet body, special
Point is that the open side of u-bracket is fixed on movable doorboard, and the facade of L-type support is fixed on the inside of cabinet body doorframe, in u-bracket
Under have aperture, fixing axle is installed therein in an aperture, in L-type support be equipped with locating shaft, limit connecting rod one end installation
In fixing axle, the other side is equipped with guide groove, and the end of guide groove is equipped with circular hole, and the diameter of circular hole is greater than the width of guide groove,
The locating shaft that lower part is equipped with boss protrudes into guide groove.
Compared with the prior art the utility model has following distinguishing feature and good effect: the utility model u-bracket
It is separately fixed on movable doorboard and cabinet body doorframe with L-type support by bolt, fixing axle is housed, in L-type support in u-bracket
Equipped with locating shaft, limit the both ends of connecting rod by self-locking nut respectively with fixing axle and position axis connection, in process of production, U
Stainless steel materials can also can be selected, using integrated folding according to the high-quality cold-rolled steel sheet of cabinet body material selection in type bracket and L-type support
Roll forming processing technology effectively improves the apparent visual of limiting device, while u-bracket has aperture up and down without welding, when
It above use when aperture, realizes that a movable doorboard left side is opened, when using lower aperture, realizes that the movable doorboard right side is opened, can meet simultaneously
The different enabling direction in left and right；One end of limit connecting rod is mounted in fixing axle, and the other side is equipped with guide groove, the end of guide groove
Equipped with circular hole, the diameter of circular hole is greater than the width of guide groove, and locating shaft protrudes into guide groove, and overall structure is simple, and fixing piece is adopted
With standard fitting, later maintenance is simple, reliably, improves the safety of limiting device, when locating shaft is along on limit connecting rod
When guide groove linear slide is to circular hole, the boss on locating shaft is caught in circular hole, is fixed movable doorboard, is reached the mesh of limit
, only need for limit connecting rod to be lifted up at closing time, it is convenient and efficient, at the same avoid because external force or door-plate fall off and
It causes control to make mistakes, improves safety.

The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is a kind of structural schematic diagram of the utility model.
Fig. 2 is a kind of structural schematic diagram that the utility model limits connecting rod.
Fig. 3 is the utility model u-bracket, L-type support and limit connecting rod attachment structure schematic diagram.
Fig. 4 is the structural schematic diagram that the utility model locating shaft and limit connecting rod are fixed.
Specific embodiment
A kind of door-plate limiting device, referring to Fig.1,2,3,4, including movable doorboard 1 and cabinet body 2, the open side of u-bracket 3
It is fixed on movable doorboard 1, the facade of L-type support 4 is fixed on the inside of cabinet body 2 doorframe, and about 3 u-bracket has aperture, when making
It when with top aperture, realizes that 1 left side of movable doorboard is opened, when using lower aperture, realizes that 1 right side of movable doorboard is opened, fixing axle 5 is mounted on
Above u-bracket in aperture, locating shaft 6 is housed in L-type support 4, one end of limit connecting rod 7 is mounted in fixing axle 5, the other side
Equipped with guide groove 8, the end of guide groove 8 is equipped with circular hole 9, and the diameter of circular hole 9 is greater than the width of guide groove 8, and lower part is equipped with boss
10 locating shaft 6 protrudes into guide groove 8, and locating shaft 6 can be slided in guide groove 8, when locating shaft 6 is along leading on limit connecting rod 7
When sliding into circular hole 9 to slot 8, the boss 10 on locating shaft 6 is caught in circular hole 9, has the function that limit, when needing door-plate 1
When closing, limit connecting rod 7 can be lifted up.
