Description

Electric box door knob lock

Technical field

The utility model relates to a kind of electric box door knob lock.

Background technology

In the prior art, be used for electric box door knob lock, can be divided into roughly that lockset and door knob are connected with together and two kinds of structures that lockset and door knob separate installing, wherein, lockset and door knob are connected with together, as No. the 233697th, Taiwan utility model patent (Lock set improvement one), it props up rotating shaft with whirlpool type spring one end, the other end props up the articulated section of door knob, when door knob was not subjected to the lockset blocking, door knob was upspring by whirlpool type spring, and user's rotary door is opened drive hook sheet, close the electric box door-plate, this structure must be provided with a room that can hold lockset at an end of door knob, and its press section is to be articulated in the pedestal groove by latch and a spring, relatively rotates thereby press section and pedestal are formed, but when the user firmly pushed the press section, door knob broke away from the press section blocking and upsprings.

Yet this door knob that gets structure must be set up room and hold lockset, and the press section need use latch to articulate, because the complexity of processing assembling causes the lifting of manufacturing cost; On the other hand, if when this structure is used for the water-proof type electric box, owing to do not possess water-proof function, moisture content can infiltrate in the electric box from the position, gap of latch.

The door knob lock that lockset and door knob are installed separately, its structure is roughly similar to the utility model, and the button locking device need be set upspringing or folding of control gate handle, as No. the 451993rd, Taiwan utility model patent communique (structural improvement of door knob lock), the pivot portion of the handle of this door knob lock is positioned at the eccentric position in relative pivot hole and the central siphon of pedestal is being provided with spring and sliding sleeve between the position of hook sheet and pedestal, pull handle the time, the hook sheet can move back and forth.This structure is by the design of spring and sliding sleeve, makes the hook sheet have certain restoring force and because very close to each other with the electric box door-plate, the hook sheet can be all closely blocking live door-plate, and can not become flexible.

Though this structure also has the button locking device, yet the button locking device of this structure is formed comparatively complexity, makes to make and the assembly cost raising; On the other hand, if this door knob is locked when being applied to the water-proof type electric box, must install a waterproof gasket that adapts with floor, seat bottom periphery additional, increased the difficulty of assembling, and waterproof effect is relatively poor, and moisture content infiltrates in the electric box easily, causes the damage of part in the electric box.
