Abstract

The utility model discloses a lock device, especially is used for locking the top cover of a flip type cabinet on the cabinet body. The device comprises a lock body, a lock bolt and a lock catch. The lock body is equipped with a lock core, the lock bolt is provided with a connection hole which is cooperated with and connected to the front end of the lock core, and the front end of the lock bolt has a diagonal plane. The lock catch is a nose-like wing structure, both of the two wings of the lock catch are provided with an installing hole, a guide groove is arranged on both sides of the nose-like part of the lock catch, both sides of the guide groove of the lock catch are respectively provided with a guide surface, and a locking ridge is arranged between the two guide grooves of the lock catch. The utility model, employing the cooperation of the arc lock bolt and the circular arc surface of the lock catch, changes the structure mode of the lock catch, and allows easier processing and more firm fix of lock catches as well as saves equipment investment.

Description

A kind of locking device

Technical field

The utility model relates to a kind of locking device, particularly is applied to the cap lock of cover-lifting type rack is tightened on the cabinet.

Background technology

At present, not enough below the employed locking device ubiquity in the cover-lifting type rack: several metal solder form, and the welding location easily deviates, and the sheet metal insufficient strength; Need the mould punch forming, the mould spending is big, is not suitable for the many variety production of small lot; The pass closed procedure has some setbacks, and the thrust after closing is not enough, causes the rack seal degree not enough.

The utility model content

The utility model adopts the arc dead bolt to cooperate with the arc surface of snap close, has changed the frame mode of snap close, makes snap close processing more convenient, and is fixing more firm, saves equipment investment.

The technical scheme that its technical problem that solves the utility model adopts is, makes a kind of locking device, and this device comprises lock body, dead bolt, snap close; Be furnished with lock core in the lock body, have connecting hole on the dead bolt, the front end of this hole and lock core is connected, and the dead bolt front end also has scarf; Snap close is a nose type band wing structure, the snap close both wings are provided with installing hole, and snap close nose type both sides are provided with gathering sill, and snap close locked groove both sides are provided with spigot surface, be provided with the locking ridge in the middle of the snap close locked groove, aforementioned dead bolt is pressed on the locking ridge at last by gathering sill, the spigot surface of snap close.

Use the rack lock body of above-mentioned locking device to be fixed to by being threaded on the cabinet of rack, snap close is by being threaded, riveting or spot weld on the rack top cover; By the key rotary locking cylinder, lock core drives dead bolt and rotates, and the scarf of dead bolt is positioned in the gathering sill of snap close; Be rotated further, scarf slides along spigot surface, and last scarf slips over the locking ridge, and the locking ridge contacts with the dead bolt cambered surface, forms interference fit, and the rack top cover is compressed.Because the scarf and the spigot surface magnitude of interference are few, locking process leicht fallen D/A, good hand touch.

This buckle structure is simple, and easy making process need not the die sinking tool, good economy performance; The cold hardening effect that bending forms has played the raising effect to structural strength, so the intensity height.

The specific embodiment

In the utility model, a kind of more excellent embodiment is for adopting following a kind of technical scheme, as Fig. 3, Fig. 4, Fig. 5 and shown in Figure 6, dead bolt 6 is provided with connecting hole 61, scarf 62, cambered surface 63, and this dead bolt 6 is riveted on the lock core front end 51 of lock body 5 by perforate 61; Nose type band wing snap close 4 both wings are provided with installing hole 41, and these snap close both sides are provided with gathering sill 42, and this snap close locked groove is made up of spigot surface 43, locking ridge 44; When rotary locking cylinder 51 was locked, front end scarf 62 at first snapped in gathering sill 42 and positions, then rotation, and scarf 62 slips over locking ridge 44 along spigot surface 43, and this moment, cambered surface 66 contacted with the locking ridge; Continue rotation, enter locking state.

Fig. 1 and Fig. 8 have shown that locking device is assembled to the state on rack cabinet 1 and the top cover 2, to be locked before, the arc opening of dead bolt opens, and makes things convenient for the decline of snap close.

Fig. 2 and Fig. 9 have shown locking state, and the locking ridge 44 of snap close forms interference fit with the cambered surface of dead bolt 63, makes top cover be in lock-out state closely.

Fig. 7 has shown the expansion shape of snap close, and its process can be: the common metal plate cuts into shape shown, then along the center 1, center 2, center 3, center 4, center 5 bending successively, form snap close 4 shown in Figure 3.This snap close only needs generic disk metalworking equipment, need not other die sinking; Simple and easy to do.

The above embodiment has only expressed embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
