Description

Plastic surface lock

Technical field

The utility model relates to electric cabinet locks, are a kind of plastic surface locks.

Background technique

Electric cabinet lock refers to the door lock for electrical cabinet door, such electrical cabinet be usually by steel material be process for The normal work of component is protected, electric cabinet lock is set in the cabinet door of electrical cabinet.The handle of existing some such door locks is set There is button, the application number 201020697653.7 as disclosed in Chinese patent literature, authorized announcement date 2011.08.10 is practical new Type title " pick-proof scratching preventive planar lock "；The flat lock includes pedestal, lock, shaft, handle, button, lock core component, pressing plate, sealing Pad, steel bolt, door bolt, pedestal is interior to be equipped with shaft, lock, button, is equipped with lock core component in handle；Its main points is the pedestal and sealing The gasket for padding junction is equipped with projective table type positioning bar；One end of the button is equipped with latch hook, and latch hook is set to the bottom of handle. The bottom of the handle is equipped with plastics fixed block；The flat lock makes handle locking in pedestal by lock core component or lock；It presses Button is pressed, handle pops up pedestal, rotational handle, and handle drives shaft rotation, and shaft drives the rotation of steel bolt.But the said goods and same Locking mechanism design in class product between button and handle is not good enough, and production cost is higher, most of more difficult use of main component Plastics are made, and door-plate thickness requirement when installation is higher.

Summary of the invention

To overcome above-mentioned deficiency, the purpose of this utility model is that a kind of plastic surface lock is provided to this field, makes its solution Locking mechanism design in existing similar product between button and handle is not good enough, and main component lacks plastics and is made and causes to be produced into This is higher, and the technical problem that installation is more inconvenient.The purpose is to what is be achieved through the following technical solutions.

A kind of plastic surface lock is equipped with shaft, the handle of one end stretching pedestal of shaft in pedestal one end of the flat lock Slot, and connect with handle groove inner handle one end of pedestal by pin, junction is equipped with torsional spring, and the other end of shaft stretches out pedestal Bottom tethered and connect with steel by backing-up screw, the shaft of pedestal, which is stretched out, is equipped with locating piece, the junction of pedestal and shaft at hole Equipped with sealing ring；Its structure designing points is that the pedestal of the handle other end is equipped with button assembly, the lock tongue lid of button assembly The end fastener of inner cover latch hook one end and handle closes, and the other end of cover lock hook and the button of button assembly offset, button in pedestal The spring and button of bottom are fixed in pedestal by button screw and gasket, and the cover lock hook of lock tongue lid is in L-shaped elastic slice, button Positioned at elastic one end of elastic slice.While driving the cover lock hook end of lock tongue lid to move down by button in above structure, lid The latch hook other end generates elastic rotation, the end hook disengaging of cover lock hook and handle, and handle can pass through torsional spring and pop up pedestal, lock tongue The cover lock hook of lid is separate structure or integral structure.

The cover lock hook of the lock tongue lid is linked together with rear cover, and lock tongue lid is fixed on the turret terminal of pedestal by rear cover screw Bottom.Above structure had both been used as the rear cover at pedestal button to use convenient for lock tongue lid, used but also as the lock tongue of handle, and By being used as plastic part integrated injection molding below.

Lower section outer diameter is symmetrically arranged with button and lower button, upper button and the setting of lower button two-by-two at the skirt of the pedestal In in the button frame slot of pedestal.Consequently facilitating the flat lock is suitable for the installation of door-plate mounting hole, i.e., limited by the skirt of pedestal After door-plate mounting hole, pedestal is fixed on door-plate mounting hole by upper button and lower button, and upper button and lower button pass through In the button frame slot of the button part indentation pedestal of button frame one, or being formed below with by way of pedestal one.

The pedestal is plastic part, upper button and lower button and pedestal integrated injection molding.Consequently facilitating the production of pedestal, And upper button and lower button are integrally formed with pedestal.

The button, handle, shaft and/or lock tongue lid are plastic part.To further decrease being produced into for the flat lock The weight of this and the flat lock.

The structure design of the utility model is reasonable, and use, installation are simple, assembles, is convenient for production, production cost is low；It is suitble to It is used as the flat lock with handle and lever knob and the structure of similar product is improved.
