Abstract

The utility model relates to an electric cabinet door lock, which is composed of a locking part and a transmission part. The utility model is characterized in that a handle is connected with a gear by transmission, and the handle drives a rotating shaft, a transmission shaft and a lock bolt to rotate through the square sleeve joint between shafts. The gear drives an upper rack bar and a lower rack bar to make upward and downward linking, the handle is penetrated with a handle pin, and the inner side of the handle is provided with a pressure spring. Because the square sleeve joint is used between shafts, at the time of installation, the thickness of an electric cabinet door plate is between 1-3 mm to reach the contraction and regulation actions. The handle and a casing back surface of the rotating shaft are provided with clamp springs to ensure the stability of the installation position of the handle. In the transmission mechanism, as long as the installation directions of the transmission shaft, a positioning piece and the lock bolt are changed, the purpose that a door is opened leftwards and rightwards can be realized.

Description

Gear linkage type electricity cabinet door lock (MS828 door lock)

The utility model relates to mechanical five metals field, is a kind of gear linkage type electricity cabinet door lock, also is called the MS828 door lock.

As everyone knows, the kind of door lock is more, but their majorities are " bolt " formula structure.The electricity cabinet door lock, though also be provided with multi-faceted retaining mechanism as door locks such as high and low pressure power distribution cabinet, switch board, numerical control casees, the function design owes reasonable.

The purpose of this utility model is, a kind of gear linkage type electricity cabinet door lock (MS828 door lock) is provided, and owes rational problem to solve electric cabinet door lock retaining mechanism design.Make its locking or unlatching possess the interlock form, the special door lock of simple operation, safe firm type.

Above-mentioned General layout Plan is such: pin electric cabinet with locking bolt, upper rack, following three orientation of tooth bar during locking, pressing button during unlatching, handle is upspring to 90 ° of counter clockwise direction turns again, drive locking bolt, upper rack, tooth bar resets down, and door lock is in opening.Open or locking all by handle with rotating shaft, power transmission shaft, gear, upper rack, the interlock of tooth bar, locking bolt is implemented down, if the door lock orientation that is locked must change, then adjust its orientation by keeper.

The advantage of this electric cabinet door lock is that structure design is comparatively compact, the layout of functor, and interlock is comparatively reasonable, and the operation of configuration design uniqueness in addition, especially handle and button is rich in the new meaning sense.Therefore, the release of this door lock is subjected to user's favor surely.

Referring now to above schematic diagram, and in conjunction with the embodiments its feature is further described: gear linkage type electricity cabinet door lock (MS828 door lock) is made up of locking and transmission two parts, promptly by locking bolt 1, following tooth bar 4, upper rack 5 constitutes lock portion, by handle 2, button 3, decorative panel 6, keeper 7, gear 11, housing 14, rotating shaft 16, power transmission shaft 17, lock core 22 grades constitute running part, handle 2 is in transmission connection with gear 11, be by the moving rotating shaft 16 of between centers square sleeve tape splicing by handle 2, power transmission shaft 17, locking bolt 1 rotates, and gear 11 drives upper rack 5 again, following tooth bar 4 is made interlock up and down; Handle 2 is installed with handle pin 18, is provided with stage clip 19 in handle 2 inboards, is connecting the fixedly locking bolt screw rod 12 of locking bolt 1 usefulness in housing 14 outsides.Decorative panel 6 is provided with sealing mat 21, and its boss is to be close to cabinet plate 24 when installing; Button 3 is arranged on the lower end part of handle 2, is provided with spring 23 in button 3; In the rectangular frame of housing 14 and locking bolt 1, be provided with keeper 7.

Embodiment: this electricity cabinet door lock is applicable to that indoor outer middle and high shelves door cabinet is supporting with lock, the usefulness of closing or opening as door locks such as height piezoelectricity cabinet, switch board, numerical control casees.Handle is by the square 7 * 7mm socket of between centers, it is locking state when handle is in Fig. 1 state just as the connected mode of box spanner, and the between centers square sleeve is a half-twist, locking bolt pins a door cabinet frame work, and upper and lower tooth bar extends respectively to penetrate in the cabinet frame work hole by extension bar locatees.Key is inserted key hole, and the handle key that resets changes half-turn and gets final product.As shown in Figure 4, handle is an ejector button, and handle is gone to 90 ° to the direction of arrow, and upper and lower tooth bar shortens, and the door cabinet promptly is in opening.Lock portion and running part are the one by 2 Bolt Connection, install all simple.Because between centers adopts square socket, the electric cabinet door-plate thickness during installation can play the contraction regulating action between 1-3mm, and does not influence assembling and use.At handle, the corresponding back side of shell of turning cylinder jump ring is housed, to guarantee that handle does not break away from relative position.In transmission mechanism, as long as conversion power transmission shaft, keeper, locking bolt installation direction, can realize that a left side or right open the door.Also can need be mounted to single-point or any door lock at 2, and need not renewal part by the user.The preposition sealing mat of cabinet plate is housed in whole door lock, respectively is provided with an O RunddichtringO, make it possess the waterproof and dustproof function, can when turning handle, reach comfort again because of damping action at rotating shaft, turning cylinder.

Decorative panel (being lock body) is the foursquare arc cuboid, and the ratio design is moderate, and four skew back faces set off out handle and button, and is consistent concavo-convex streamline shape, and uniqueness handsome in appearance is rich in third dimension.Small and exquisite, the succinct and lock body secure and reliable connection of rearmounted housing, volume.

Operation with use: key counterclockwise changes 180 ° with lock core, presses the button, and handle ejects about 45 ° automatically, 90 ° of turning handles (right hand door rotates counterclockwise, and the left hand door is clockwise) again, locking bolt and up and down tooth bar shrink simultaneously, the cabinet door is opened.Otherwise handle goes back to 90 °, and tooth bar restored simultaneously about locking bolt reached, and pinned the cabinet door, again handle was pressed original position, and with 180 ° of lock core up time direction commentaries on classics, handle promptly is lockable with key.

This electricity cabinet door lock is the ideal new product of structure, shape in the present mechanical five metals, and certain application value is arranged.
