Abstract
The present invention provides a kind of new-type switchgear lifting door locks, including being located at the limited block jack of doorframe side, the hanging plate of switch cabinet door side being connected to the mating limited block of the limited block jack, door lock rocking handle and sliding up and down, the limited block is fixed on the hanging plate, gear is fixed in shaft on the door lock rocking handle, the rack engaged with the gear is fixed on the hanging plate.The weight of hanging plate is less than the weight of entire doorframe in the present invention, thus lock or open the door lock can be than the more laborsaving convenience of original design, and last a long time.
Description
Technical field
The present invention relates to a kind of switchgear, particularly a kind of new-type switchgear lifting door lock.
Background technology
The lifting door lock used in many switchgears opens the method for door using entire doorframe is promoted at present, and this design exists
It needs operating personnel are relatively elaborate could promote entire doorframe in practical operation, realize the unlatching of door lock and locks.While with
Frequent operation and the passage of time, the larger weight of doorframe itself can damage the component of the door lock and doorframe junction, door lock
Self-strength is also more and more insufficient.
Invention content
The present invention, which provides, a kind of to be easier to open and lock and new-type switchgear lifting door lock that service life is longer.
To achieve these goals, the technical solution taken of the present invention is：
The new-type switchgear lifting door lock, including being located at the limited block jack of doorframe side, being inserted with the limited block
The mating limited block in hole, door lock rocking handle and the hanging plate for being connected to switch cabinet door side is slided up and down, the limited block is consolidated
It is scheduled on the hanging plate, gear is fixed in the shaft on the door lock rocking handle, is fixed on the hanging plate and is nibbled with the gear
The rack of conjunction.
The hanging plate is trough plate, and the both sides of the hanging plate are equipped with several opposite limiting slots；It is set in the cabinet door side
Have a side slot for accommodating the hanging plate, be fixed on the inside of the side slot it is several pass through the hanging plate both sides and with the limiting slot
The location structure being slidably matched.
The location structure includes positioning pin fixing piece and the positioning pin being plugged in the positioning pin fixing piece, described fixed
Position pin fixing piece is fixed on the side slot side, and the side slot opposite side is equipped with the jack for being inserted into the positioning pin, described
The limiting slot of positioning pin fixing piece and the positioning pin respectively with the hanging plate respective side is slidably matched.
The scraper plate bottom is provided with the rectangular opening for accommodating the gear, and is equipped with upright limit in the rectangular opening upper and lower sides
Position plate, the limiting distance between plates are not less than the sum of the gear diameter and the hanging plate movable distance.
The gear is half gear.
The limited block is the L-shaped limited block that end extends downwardly, and the limited block jack is located on the doorframe side
Protrusion top surface.
The positioning pin fixing piece is fixed by hexagon socket head cap screw and the positioning pin.
Using above-mentioned technical proposal, when use, rotates door lock rocking handle, is driven above and below hanging plate by rack and pinion drive mechanism
It slides, the limited block on such hanging plate also inserts or pull out limited block jack therewith.The weight of obvious hanging plate is less than entire doorframe
Weight, therefore lock or open the door lock can be than the more laborsaving convenience of original design, and last a long time.
In order to ensure the intensity of door lock, using the hanging plate of flute profile harden structure, and pass through several position limiting structures and realize that slip is matched
Conjunction and limit effect can improve the reliability and service life of door lock in this way.The concrete structure of position limiting structure is for manufacturer
Just it designs.Limiting plate has limiting and protects the double action of geared parts, and the length of rectangular opening is then to consider gear and hanging plate
Sliding distance design.Also there is limit effect using the engagement of half wheel and rack.

Specific embodiment
Below against attached drawing, by the description of the embodiment, making further details of theory to the specific embodiment of the invention
It is bright, those skilled in the art to be helped to have more complete, accurate and deep understanding to inventive concept of the present invention, technical solution.
As shown in Figs. 1-2, it the present invention provides a kind of new-type switchgear lifting door lock, including limited block jack 8, is plugged into
Limited block 5, door lock rocking handle 2, hanging plate 1 and the location structure of limited block jack 8.Frame side face has upper and lower two protrusions, convex
Go out portion top surface equipped with limited block jack 8.Limited block 5 is fixed on 1 bottom of hanging plate, the L-shaped limited block extended downwardly for end.
Side slot is equipped in switch cabinet door side, side slot is used to accommodate hanging plate 1.Hanging plate 1 be trough plate, bottom court
To cabinet door door-plate.Trough plate both sides are designed with several limiting slots, and the limiting slot of both sides is pairs of.Location structure is mounted on side
It is slidably matched on the inside of slot with limiting slot, and passes through limiting slot both sides.
Location structure includes positioning pin fixing piece 7 and plugged and fixed the positioning pin 6 in positioning pin fixing piece 7.Positioning pin
Fixing piece 7 is fixed on side slot side, and side slot opposite side is equipped with the jack for being inserted into positioning pin 6.Positioning pin 6 is inserted into from jack
In positioning pin fixing piece 7.Positioning pin fixing piece 7 is fixed by hexagon socket head cap screw and the positioning pin 6.7 He of positioning pin fixing piece
Limiting slot of the positioning pin 6 respectively with 1 respective side of hanging plate is slidably matched.
The shaft of door lock rocking handle 2 is fixed with gear 4 across door-plate one end, and half gear with limit effect can be used.Tooth
Item 3 be fixed on the inside of hanging plate 1 and with the engaged transmission of gear 4.1 bottom of hanging plate is provided with the rectangular opening for accommodating gear 4, and in rectangle
Hole upper and lower sides are equipped with upright limiting plate.Limit distance between plates not less than 4 diameter of gear and hanging plate about 1 movable distance it
With.Limiting plate has limiting and protects the double action of 4 component of gear, and limiting plate should not influence tooth when normal condition hanging plate 1 moves
4 rotation of wheel.
When cabinet door is opened in unlock, user rotates door lock rocking handle 2, is driven through 4 rack 3 of gear and drives hanging plate 1 upward, hanging plate
Limited block 5 on 1 is extracted therewith from limited block jack 8.Negative direction Revolving door lock rocking handle 2 can lock the door lock.The weight of hanging plate 1
Less than the weight of entire doorframe, thus lock or open the door lock can than the more laborsaving convenience of original design, and the service life compared with
It is long.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that present invention specific implementation is not by aforesaid way
Limitation, as long as employ the method for the present invention design and technical solution carry out various unsubstantialities improvement or not improved
Present inventive concept and technical solution are directly applied into other occasions, within the scope of the present invention.
