Description

Lockset

Technical field

The utility model relates to a kind of lockset, particularly a kind of lockset that is used on the products such as door of refrigerator, electric cabinet door, toolbox door.

Background technology

Be not with door lock in the products such as existing refrigerator, electric cabinet, tool box, its shortcoming is to be opened by the infant easily and have an accident or easily Men Zhen is opened in transit and impaired.

Summary of the invention

In order to solve the problem that is opened easily of door in the products such as existing refrigerator, electric cabinet, tool box, the utility model provides a kind of lockset, it can strengthen the said goods safety and simple in structure, cost is low.

Technical scheme:

A kind of lockset, form by lock tube, lock core, dead bolt and key, wherein lock core is positioned at the cylindricality cavity of lock tube, it is polygonal spoon chamber that the lock core front portion has cross section, the lock core rear portion has the barrel-shaped cavity that communicates with the spoon chamber, order is placed spring and apical axis in the barrel-shaped cavity, and it is external to prevent that apical axis from being ejected barrel-shaped cavity by spring to be provided with stopping means between apical axis and lock core; Spoon chamber cross section matches with the key cross section; It is characterized in that apical axis is the little cylindrical body in big middle part, two ends, is provided with the transition circle cone between middle part and afterbody; The lock core rear sidewall has the radial direction through hole of built-in lock pearl, and the axial positions that the lock tube inwall is corresponding with the lock pearl has at least one axial locked groove; When not inserting key, the transition circle cone under the spring force effect on the apical axis will be locked in the locked groove that the pearl outer end heads into lock tube, and lockset is locked; After inserting key, apical axis moves backward, and separate with the lock pearl on the surface of its transition circle cone, and the lock pearl is rotated key and drives the lock core rotation by the spoon chamber in the middle part of apical axis, and the lock integument is pressed in the lock core, and separate with locked groove lock pearl outer end, realizes unblanking.

Described lockset, the dual-side that it is characterized in that locked groove on the lock tube inwall is a hypotenuse.Effect is to be convenient to lock pearl bounce back in lock core when unblanking.

Described lockset, the dual-side that it is characterized in that locked groove on the lock tube inwall are the hypotenuses that is mutually an angle of 90 degrees.In fact its mutual angle can be between 60 to 120 degree, and just 90 effects when spending are best.

Beneficial effect:

Owing to adopted technical scheme described in the utility model, lock structure is simple, cost is low, and after on the door of products such as refrigerator, electric cabinet and tool box this lockset being installed, security performance is improved.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the internal construction schematic diagram of lockset described in the utility model.

Fig. 2 be Fig. 1 along A---the sectional view of A line.

Fig. 3 be among Fig. 1 embodiment apical axis by the schematic diagram of key (not drawing among the figure) when pushing up unlocking condition.

Among the figure 1, lock tube, 101,102, locked groove, 2, lock core, 201, stopper slot, 202, button hole, 203, the spoon chamber, 3, apical axis, 301, cone, 302, the middle part, 4, banking pin, 5, the lock pearl, 6, spring, 7, clasp nail.

The specific embodiment:

As can be seen from Fig. 1, described lockset, form by lock tube 1, lock core 2, dead bolt (not drawing among the figure) and key (not drawing among the figure), lock core 2 is positioned at the cylindricality cavity of lock tube 1, it is polygonal spoon chamber 203 that the lock core front portion has cross section, the lock core rear portion has the barrel-shaped cavity that communicates with the spoon chamber, and order is placed spring 6 and apical axis 3 in the barrel-shaped cavity, and the clasp nail 7 on the apical axis 3 constitutes stopping means with cylinder side to button hole 202; Apical axis 3 is the little cylindrical body in big middle part, two ends 302, is provided with transition circle cone 301 between middle part 302 and afterbody; The lock core rear sidewall has the radial direction through hole of built-in lock pearl 5, and the lock tube inwall has two axial locked

grooves

101 and 102; Locked

groove

101 and 102 dual-side are hypotenuses on the lock tube inwall as can be seen from Fig. 2.

As can be seen from Fig. 3, when apical axis by key (not drawing among the figure) when pushing up unlocking condition, lock core is promptly rotatable, lock core rotates 180 degree back dead bolts (not drawing among the figure) and is in unlocking condition among the figure, can extract key out, cone 301 surfaces will be locked pearl 5 and be headed in the locked groove 102; When locking, insert key again and extract lock core backward rotation 180 degree backs out key, the cone 301 on the apical axis 3 will be locked pearl and head in the locked groove 101 lockset sealed (unillustrated dead bolt and lock core are sealed with the door body synchronously among the figure).

Cone 301 in the utility model has in fact only used its hypotenuse, in fact also can beveling, just cause cone for simplified processing process.

Claims

1, a kind of lockset, form by lock tube, lock core, dead bolt and key, wherein lock core is positioned at the cylindricality cavity of lock tube, it is polygonal spoon chamber that the lock core front portion has cross section, the lock core rear portion has the barrel-shaped cavity that communicates with the spoon chamber, order is placed spring and apical axis in the barrel-shaped cavity, and it is external to prevent that apical axis from being ejected barrel-shaped cavity by spring to be provided with stopping means between apical axis and lock core; Spoon chamber cross section matches with the key cross section; It is characterized in that apical axis is the little cylindrical body in big middle part, two ends, is provided with the transition circle cone between middle part and afterbody; The lock core rear sidewall has the radial direction through hole of built-in lock pearl, and the axial positions that the lock tube inwall is corresponding with the lock pearl has at least one axial locked groove.
