Technical field
The present invention relates to electric power and communication cabinet assembling field, specifically a kind of cabinet door opens locking device.
Background technique
Along with the fast development of China's electric power system and communication system, increasing equipment is installed concentratedly in rack, and rack is arranged in outdoor pole or plateau, needs outdoor study or high-lift operation to install.When open air or high-lift operation, because misoperation or large wind effect can cause back and forth rocking of cabinet door, cabinet door is caused to close suddenly and the operating personnel that crushes or damage.
Summary of the invention
In order to solve the problem, the invention provides a kind of cabinet door and opening locking device, locking position problem when cabinet door is opened when solving outdoor study.
The present invention is by the following technical solutions: a kind of cabinet door opens locking device, it is characterized in that, comprise guiding fixed plate, position-limited shaft, connecting plate, attachment screw, guiding fixed plate comprises riser and flat board, chute is provided with in the middle of dull and stereotyped, the right-hand member of chute connects a spacing hole, and the diameter of described spacing hole is greater than the width of chute; Described position-limited shaft is followed successively by limited step, positioning step, guiding step from top to bottom and is connected step, described limited step, positioning step, guiding step be connected step and be cylindrical structural, the diameter of positioning step rounded bottom surface is identical with the diameter of spacing hole, the diameter of guiding step rounded bottom surface is identical with the width of chute, the diameter of limited step rounded bottom surface is greater than the diameter of positioning step rounded bottom surface, and the diameter connecting step rounded bottom surface is less than the diameter of guiding step rounded bottom surface; The left and right two ends of described connecting plate are respectively equipped with the first through hole and the second through hole, the diameter of described first through hole is identical with the diameter connecting step rounded bottom surface, described connection step from top to bottom successively through chute and the first through hole, and is connected with the first nut by screw thread; Described attachment screw comprises nut and screw rod, and the diameter of nut is greater than the diameter of the second through hole, and the lower end of screw rod is passed the second through hole and is connected with the second nut thread.
Preferably, limited step, positioning step, guiding step overlap with the central axis being connected step.
Preferably, described riser and flat board are mutually vertical.
Further, the lower end of described connection step is provided with the first tapped hole traversing and connect stepped cylinder, is connected with the first latch in described first tapped hole.
Further, the lower end of described screw is provided with the second tapped hole traversing and connect stepped cylinder, is connected with the second latch in described tapped hole.
Preferably, the first described nut and the second nut are slotted nut.
Further, described connecting plate and the direct screw of the second nut are provided with annular cushion block.
Further, spacing hole is multiple, and multiple spacing hole is equidistantly distributed on chute.
Further, connecting plate comprises fixed plate and extension board, and fixed plate is the structure of hollow, in the inner chamber of fixed plate, be provided with extension board, and extension board can move in fixed plate inner chamber, between fixed plate and extension board, be provided with lock bolt.
The invention has the beneficial effects as follows:
1, by the diameter difference of the different step of position-limited shaft, realize corresponding function, limited step largest diameter, responsible being fixed on by position-limited shaft on guiding fixed plate does not depart from; Positioning step Ground Diameter is consistent with spacing hole diameter, and therefore when positioning step engages with spacing hole, position-limited shaft is in locking state with guiding fixed plate, and cabinet door can not because of unexpected closedown; The basal diameter of guiding step is consistent with trough width, guiding step can be moved left and right in chute, realize the open and close of cabinet door; Connected unit rank Ground Diameter is minimum and consistent with the first through-hole diameter, can ensure to combine closely between connecting plate and position-limited shaft, both there will not be and rocked, and can realize again the operation of lifting position-limited shaft.
2, dull and stereotyped and connecting plate is in parallel state, when cabinet door is closed, flat board is just in time fitted in plate upper surface, and connecting plate is positioned at the edge of cabinet lower surface, because the spacing of the interior of equipment cabinet of power equipment is larger, therefore can not take the space of cabinet inside, go for the rack of all splendid attire power equipments.
3, for the arrangement environment that cabinet width is different, and the size of internal unit, artificially can adjust the fixed position of guiding fixed plate and attachment screw, thus limit the unlatching maximum angle of cabinet door, because the angle between connecting plate and guiding fixed plate can change between 0-180 degree, cabinet door opening angle can be selected arbitrarily between 0-180 degree.
